摘要： A testing machine includes a stand and a test device. The stand includes a base, box frame, a slide device driven to slide by a motor, and a control system controls the force applied on the test specimen. The test device is coupled at the slide device for performing various hardness tests consisting of Rockwell hardness test, Vickers hardness test, Brinell hardness test, micro-hardness test, and tension-compression test. The test device includes a force sensor and a data processing circuit converting an analog signal of the force sensor into digital data to interface with the control system.

摘要： A modular hardness testing machine has a measuring component and a set of frames. The measuring component includes a housing and locating slot. The measuring component has a locating slot configured to receive a frame. The locating slot allows a user to modularly interchange the frame. The measuring component's housing encloses a presshead, which encloses a load cell having through-holes holding transmission pins. The first end of each transmission pin contacts a displacement measurement sleeve, and a second end contacts a transmission plate. A motor is mounted to the housing. The motor is connected to a reduction drive. The reduction drive reduces speed and drives a lead screw mounted on a bearing mount, and a moveable presshead is driven by the lead screw.

摘要： An indentation type hardness tester applies a predetermined force to an indenter and the indenter produces an indentation on a test specimen, and then measures the shape and size of the indentation. The hardness tester has a tester body and different frames. The tester body has a cavity and a magnetic base. The user selects different frames based on measurement needs and installs the frame into the magnetic base of the tester body. The testing head is equipped with an optical imaging system, the front end of the testing head is equipped with a removable load cell, and the front end of the load cell is equipped with an indenter. The indenter, load cell and optical system are coaxially oriented. A motor moves the tester body to perform the indentation.

摘要： A hardness testing device includes an elongated guiding tube, a test member, an impact actuator, and a transducer. The elongated guiding member has a bottom impact opening for contacting with the work piece surface and a coil seat integrally provided on an outer circumferential surface of the guiding tube at a position close to the impact opening. The impact actuator is provided on an upper portion of the guiding tube for applying an impact force against the test member which is then driven to travel within the guiding tube at an impinging velocity and a rebound velocity. The transducer includes an electric coil coaxially wound on the coil seat, and is adapted to electromagnetically communicate with the test member for detecting the impinging velocity and the rebound velocity when the test member slidably passes through the coil seat so as to determine a hardness of the work piece surface.

摘要： A hardness tester includes a supporting frame having a guiding channel, a driving axle slidably disposed in the supporting frame, and a penetrating pin, having a pin head, coaxially disposed in the guiding channel in a slidably movable manner to coaxially align with the driving axle for the pin head to penetrate on a testing surface of a tested object. A linear displacement device includes a transmission shaft movably disposed in the supporting frame at a position universally contacting between the driving axle and the penetrating pin, and a displacement sensor supported at the transmission shaft, wherein when the driving axle is driven for applying a penetrating force to the penetrating pin through the transmission shaft, the linear sensor detects a linear displacement of the transmission shaft with respect to the penetrating pin for measuring the hardness of the tested object.
