摘要： In a machine tool having the spindle (110) supporting a work holder (350), means are provided for automatically operating the work holder to grip or release a workpiece and for automatically securing the work holder to the spindle or release it therefrom. Within the spindle, a compression spring (116C) acts on a slide (116B) which has claws (116) gripping a head (157) provided at one end of a holder housing (152) to draw the latter into engagement with a conical socket (115) of the spindle thereby to secure the holder. Within the holder housing (152), a compression spring (159B) urges a set of jaws (158A) into a conical socket (152A) of the housing (152) thereby to grip a workpiece (51). A hydraulic actuator (M316) mounted on fixed structure (102) is adapted both for opening the jaws and for releasing the holder from the spindle. For opening the jaws, a piston (M316B) of the actuator is moved through an initial distance X thereby to move the jaws in opposition to the spring (159B) in the opening sense. The piston acts through the intermediary of a rod (317) supported in the slide (116B) for free movement relative thereto. For release of the holder from the spindle, the piston is moved further, through a distance Y, to engage and move the slide in the sense causing the claws (116) to abut a shoulder (155B) on the holder housing and release the holder from the socket (115). Toward the end of the piston movement the claws spring radially outwards into a recess (110C) of the spindle to free the holder for removal by an automatic transfer mechanism. Several modifications are described.

摘要： PURPOSE: To index the angular position of a probe surely through a relatively simple structure by turning the probe about a selected axis. CONSTITUTION: A head 10 is secured to a vertical post 12 fitted to move through a bearing 13 in the vertical Z direction. The bearing is fitted to move horizontally in X direction on a beam 14 secured to a bearing 15 to move horizontally in Y direction. They are driven, respectively, by stepping motors 13A, 14A and 15A which are controlled by a 3-channel magnetic tape 16 through a reading head 17. The head 10 is bonded with a probe 18 having a needle 34 for measuring a work 19. When a bore 20 is measured, for example, the needle 34 is aligned with a vertical axis as shown at position 34A and when a bore 21 is measured, the needle 34 is turned to be aligned with a horizontal axis as shown at position 34C. A member 122 forms the arm of the probe 18 and it can be turned through engagement with a fixed structure.

摘要： PURPOSE: To smoothly move a stylus and widen its movement range. CONSTITUTION: A second member 20 is held on a first member 16 by a magnet and an air bearing is formed between both the members 16 and 20 to make the second member 20 movable to and away from the first member in an X and a Y direction. A third member fitted with the stylus is held on the second member 20 by a magnet 56 and an air bearing is formed between both the members 20 and 42 to make the third member 42 movable in a Z direction.

摘要： PURPOSE: To obtain a highly accurate contact probe by solving the problem of lobe and hysteresis in the movement of a stylus. CONSTITUTION: In the contact trigger probe for positioning system having a stylus 14 being biased to a rest position, the stylus 14 has first and second independent supports disposed in a housing 10. The first support has the skirt 18 of a stylus holder 12 restricted in the axial direction on the surface 20 of the housing 10. The second support has the kinematic arrangement of a cylinder 34 and a ball 36 for imparting a lateral restriction in conjunction with a plane spring 30. The first support is biased with lower force than the second support and the friction is reduced significantly. Consequently, the lobe and hysteresis are reduced in the movement of the stylus 14 resulting in a highly accurate probe.

摘要： PURPOSE: To realize a touch probe having a high sensitive mechanism by changing, in response to stylus formation due to the contact between the stylus and a work piece, the state of light reflection surface as a sensor so that changes in optical path length is detected. CONSTITUTION: A stylus 16 is, through a carrier 18, connected to a probe 10, and the carrier 18 is, through three cylinder rollers 20, supported so that it is excited to a kinematical position against a housing 12. When a work piece touches a sensing tip 26 of the stylus 16 to slightly deform the stylus 16, and the carrier 18 is displaced from its standstill position, laser light 102 incident on an interferometer cube 100 mounted on the carrier 118(18) changes the condition of a reflection surface of a mirror 106 provided as a sensor at the tip of the interferometer cube 100. The change in the reflection surface changes the optical path length of the light incident on the reflection surface, so, by detecting the change in the optical path length, a contact between the stylus 16 and the work piece is detected.

摘要： PURPOSE: To easily adjust the posture of a magazine which holds detecting elements by adjusting the relative position relation between the plate member of the magazine and a base by an adjusting means. CONSTITUTION: This mechanism adjusts the posture of the magazine 10 which holds the detecting element 12, 12... in the operation range of a coordinate positioning device. The mechanism is equipped with a base 18 for supporting plate members 20 fixed to the floor part of a device and the magazine 10, a fixing means 14 which fixes the base 18 to the floor part of the device, and the adjusting means 16 which is provided to one plate member 20 and the base 18 and applies an adjusting force to the other plate member 20 and the base 18. Then the relative position relation between the base 18 and plate members 20 is adjusted. Thus, the three-dimensional relation between the plate member 20 fixed to the device and the base 18 fixed to the device by the fixing means 14 is adjusted to adjust the posture of the magazine 10, and the danger of a collision between the device and a movable part of the magazine 10 is minimized to the suppress the danger of the collision.

摘要： PURPOSE: To position a probe easily over a wide range by setting a connector for connecting a probe with a swivel back from a swivel shaft when the probe is directing downward. CONSTITUTION: A rotor 14 is mounted rotatably on a supporting member 12 while a swivel 46 is fixed rotatably to a shaft 48 intersecting a shaft 16 perpendicularly and a probe 50 is connected with the swivel 46 through a connector 54. The connector 54 is set back from the shaft 48 of the swivel 46 when the probe 50 is directing downward. Consequently, the probe 50 can be mounted removably and can be replaced without requiring any additional positioning. When a wheel 108 is operated manually under that state, a coupling rod 90 is lowered through a rotary mechanism 94 and the supporting member 12 is uncoupled from the rotor 14. They can be coupled again by elevating the coupling rod 90 after adjusting the relative position.
