Embodiment 1

[0020] Such as figure 1 , figure 2 As shown, a device for easily measuring the hardness of a workpiece includes a hardness tester 1 and a base 2. The base 2 includes a test bench 3 and a column 4 connected to the test platform 3, wherein the column 4 is a cavity structure with an open end, and the hardness tester 1 is slidingly arranged in the column 4; the hardness tester 1 includes a cylindrical cavity shell, the hardness converter 5 is arranged in the cylindrical cavity shell, and also includes a conduit 6 connected to the cylindrical cavity shell, a test head 9 is slidably arranged in the conduit 6. A hole 7 is opened at the bottom end of the conduit 6, and an electronic coil 8 is wound above the hole 7, wherein the hardness converter 5 is electrically connected to the electronic coil 8. The hardness tester 1 also includes a transmission device 10.

[0021] The hardness tester 1 is slidingly arranged in the column 4. When the workpiece is placed on the test table 3, the...

Embodiment 2

[0023] On the basis of Embodiment 1, this embodiment also includes a handwheel 11 installed on the side of the column 4 . A bevel gear A connected to the hand wheel 11 and a bevel gear B meshed with the bevel gear A are arranged in the cavity of the column 4, wherein the axis of the bevel gear A is perpendicular to the axis of the bevel gear B and is located on the same plane. A rack is engraved on the back of the hardness tester 1, and the rack is meshed with the bevel gear B.

[0024] The hand wheel 11 is connected with the bevel gear A. When the hand wheel 11 is turned, the bevel gear A rotates, and the bevel gear A rotates to drive the bevel gear B to rotate. The bevel gear B meshes with the rack on the back of the hardness tester 1. When the hand wheel 11 turns clockwise, the bevel gear B will drive the hardness tester 1 to move downward. When the hand wheel 11 turns counterclockwise, the bevel gear B will move Drive the hardness tester 1 to move upwards, thus this embod...

Embodiment 3

[0026] This embodiment is on the basis of embodiment 1, as image 3 , Figure 4 As shown, the transmission device 10 includes a releaser 13 located at the top of the transmission device 10, a support tube 14 sleeved outside the conduit 6 and a loading body 15 movable in the conduit 6, and a transmission sleeve sleeved on the loading body 15. sleeve 16 ; the transmission device 10 also includes a spring 12 . The loading body 15 includes a connecting pipe 151 and a gripper 152 connected to the bottom end of the connecting pipe 151. There are at least two grippers 152, and the upper end of the connecting pipe 151 is connected to the releaser 13. There is a hook at the bottom. The transmission sleeve 16 is sleeved on the connecting pipe 151, the middle part of the transmission sleeve 16 is a protruding structure, and one end of the spring 12 is connected to the lower end of the protruding structure of the transmission sleeve. When the loading body 15 is loaded, the other end of ...

Abstract

The invention relates to a device facilitating the measurement of the hardness of a workpiece. The device comprises a hardness meter and a base, wherein the base comprises a testing platform and a vertical column connected with the testing platform; the vertical column is of a cavity structure with an opening at one end; the hardness meter is arranged in the vertical column in a sliding manner and comprises a cylindrical cavity shell; a hardness converter is arranged in the cylindrical cavity shell; the hardness meter also comprises a guide pipe connected on the cylindrical cavity shell; a testing head is arranged in the guide pipe in a sliding manner; the bottom end of the guide pipe is provided with a hole; an electronic coil is wound above the hole; the hardness converter is electrically connected with the electronic coil; and the hardness meter also comprises a transmission device. The device has the beneficial effects that and height adjustment of the hardness meter can be realized by gear-rack meshing when a hand wheel rotates, and the distance between the testing head and the coil is shortest by directly winding the electronic coil on the guide pipe, so that the obtained final testing result is accurate.

Description

technical field [0001] The invention relates to a hardness tester, in particular to a height-adjustable hardness tester. Background technique [0002] In the field of mechanical processing, workers generally use hardness testers to measure the hardness of products, and check whether the products produced are qualified by measuring the hardness of products. However, the distance between the coil group and the impact body in the traditional hardness tester is relatively large, and measurement errors are prone to occur. And because the hardness tester is fixed on the base, its height cannot be adjusted, so it cannot test workpieces of different heights, which seriously affects the work efficiency. Contents of the invention [0003] The invention provides a device for conveniently measuring the hardness of workpieces, aiming to solve the problems of large measurement errors, non-adjustable height and the like. [0004] Technical scheme of the present invention is as follows:...
