摘要： PURPOSE:To position a tip with high precision by detecting the shift quantity of standard shaft in the case when the standard shaft is pressed onto a throw-a way tip which is installed. CONSTITUTION:After all throw-away tips 2 are installed, a motor 24 is driven to once raise an elevation table 23, and then the table 23 is lowered, and stopped at the higher position than the above-described position. Then, the undersurface of a pressing plate 21a contacts the installed tip 2, accompanied with the lower ing of the table 23, and a standard shaft 12 is pushed up, and shifted upwardly, and the shift quantity (stroke in pushing up) of the standard shaft 2 is detected by a detector 22 and memorized, and the above-described operations are repeated. In this case, if the tip 2 is installed at the higher position than the standard position, the detection value is larger, and if installed at the lower position than the standard position, the detection value reduces, and the pertinent tip 2 and the degree of position deflection can be immediately detected, and when an allowable limit is exceeded, installation work is carried out again.

摘要： PURPOSE:To conduct automatically the work of the exchange of chips, by providing at a bite holder a clamp piece drive means whose purpose is to move in reciprocation a clamp piece in approach/separation directions to a chip fitting seat, and providing a means whose purpose is to push out the chips housed in a chip magazine to the chip fitting seat. CONSTITUTION:In the case of chips being exchanged, a clamp piece 17 is first moved in the direction of separation from a chip fitting seat 19 by means of a clamp piece drive means 51, and the pressure of pushing at the chip 13 pinched between the clamp piece 17 and the chip fitting seat 19, is released. Under this condition, one chip 13 out of a plurality of chips 13 housed in a chip magazine 23 is pushed out to the chip fitting seat 19 by means of a chip pushing out means 37. Next, the clamp piece 17 is moved again in the direction of approach to the chip fitting seat 19 by means of the clamp piece drive means 51. By this movement, the exclusion of the previously furnished chip 13 and the pinching of a new chip 13 between the chip fitting seat 19 and the clamp piece 17, are made.

摘要： PURPOSE:To perform the chip change of a clamp bite without relying on a manual work by arranging a chip extruding means extruding to a chip fitting seat by engaging with the chip of a chip receiving part. CONSTITUTION:In case of changing a chip 13, first, a machine is actuated, a clamp bite is moved to specified position, in succession, one chip 13 is delivered to a chip receiving part 23 by a chip fetch mechanism 62 from a chip magazine 61. Then, a clamp piece 17 is separated from a chip fitting seat 19 by a clamp driving means and the press of the chip 13 fitted to the chip fitting seat 19 is released, and in this state the new chip of the chip receiving part 23 is extruded to the chip fitting seat 19 by a chip extruding means 28. In succession the clamp piece 17 is again moved in the direction approaching to the chip fitting seat 19 by the clamp driving means, the chip 13 previously fitted is removed and a new chip 13 is interposed between the chip fitting seat 19 and clamp piece 17.

摘要： PURPOSE:To automatically chamfer a convex top of a pinion without using a complex control device by providing a chamfering device with a work rotating mechanism, a chamfering tool abutting on the convex top of a work, a moving mechanism for either of the chamfering tool and the work, and a pressing mechanism for the chamfering tool. CONSTITUTION:A pressing mechanism 6 presses a chamfering tool 5 at the starting point of machining on the convex top of a drive pinion 1, and a rotating mechanism 4 rotates the pinion 1 at constant speed, and a moving mechanism 3 moves the pinion 1 at the constant speed to make the chamfering tool 5 move relatively toward the end point of machining on the pinion 1. Thus an uniform lead torsional movement occurs between the chamfering tool 5 and the convex top of the pinion 1 according to the speed ratio of the rotating mechanism 4 to the moving mechanism 3 to generate force to push up the chamfering tool 5, and this force balances with the pressing force of the pressing mechanism 5 to make the chamfering tool 5 trace a nonuniform lead curve on the convex top of the pinion 1. Thus the convex top of the pinion 1 can be chamfered as much as a fixed amount.

摘要： PURPOSE:To make it possible to perform a stable and high-quality slicing, by regulating the opening of a rotary valve by means of the revolution of an electric motor, controlling the oil feed to a hydraulic cylinder and performing a feedback control using a cutting speed detector and a controlling measure. CONSTITUTION:By operating a switch, a CPU 10 gives a speed instruction to an I/O control unit, a d.c. servo-motor 5 runs at a specified speed and the input shaft of a rotary valve 3 rotates in a certain amount. Accordingly, the quantity of oil passing through the rotary valve 3 is controlled, the hydraulic oil is fed to a hydraulic cylinder 2 and a delivery table 1 rises. This rising movement is detected by a linear encoder 8, transmitted to the I/O control unit 9, the rising speed of the delivery table 1 is obtained from the feedback signal, the difference between the rising speed and the said speed instruction makes the d.c. servo-motor 5 to run normally or reversely and changes the opening of the rotary valve 3, and controls so that the real rising speed, that is to say, the cutting speed coincides with the speed instruction.

摘要： PURPOSE:To simplify the constitution of an autoloader and moreover improve the stop accuracy of an arm, by making a casing support an output shaft and providing a bearing to prevent the said shaft from moving in its axial direction. CONSTITUTION:A recess 15 being circular in its section is formed on the tip of a casing 10, and is fitted with a bearing 16 which supports an output shaft 11 rotatably, and moreover prevents it from moving in its axial direction. Therefore, when a thrust load acts on the output shaft 11, the bearing 16 supports the said thrust load to prevent impulse force from acting on a rotor 4. Thus, an arm can be directly fixed to the output shaft and used to simplify the constitution of an autoloader and sharply improve the stop accuracy of the arm.
