Embodiment 1

[0016] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the device that can adjust the level of the test workpiece includes a base 1, a cylinder 2, and the upper end of the cylinder 2 is open. The base 1 is a cylindrical cavity structure. The upper end of the base 1 has a hole smaller than the inner diameter of the base 1. The cylinder 2 is located in the cavity structure of the base 1, and further includes at least three support seats 3 installed at the bottom of the cavity of the base 1. The support seats 3 include a column 4, a lever 5 connected with the column 4 through a rotating shaft, and a through The upper end of the base 1 enters the screw 6 of the cylindrical cavity. The end of the screw 6 falls on one end of the lever 5, and the other end of the lever 5 abuts against the bottom of the cylindrical tube 2.

[0017] In this embodiment, the height of the test workpiece 12 can be adjusted by rotating the screw 6. When one end of the test workpiece 12 is high,...

Embodiment 2

[0019] In this embodiment, on the basis of embodiment 1, the end of the lever 5 in contact with the bottom of the cylinder 2 has a spherical structure.

[0020] The end of the lever 5 in contact with the bottom of the cylindrical barrel 2 is of a spherical structure, and the spherical structure prevents the lever from being damaged during the contact between the lever 5 and the cylindrical barrel 2.

Embodiment 3

[0022] In this embodiment, on the basis of Embodiment 1 or Embodiment 2, a groove 7 is opened at the bottom of the base 1 and a level measuring device 8 is placed in the groove 7.

[0023] A level measuring device 8 is placed in the tank 7, and the level measuring device 8 is taken out when it is needed, and when not in use, the level measuring device 8 is placed in the tank 7. The slot 7 provided on the base 1 saves space and facilitates the placement of the level measuring device 8.

Abstract

The invention provides a device for adjusting the levelness of a testing workpiece. The device comprises a base and a cylinder, wherein an opening is formed in the upper end of the cylinder; the base is of a cylindrical cavity structure; a hole with the diameter less than the inner diameter of the base is formed in the upper end of the base; the cylinder is arranged in the cavity structure of the base; the device further comprises at least three supporting seats which are mounted at the bottom of the cavity of the base; each supporting seat comprises a stand column, a lever connected with the stand column by virtue of a rotating shaft and a screw penetrating through the upper end of the base to enter the cylindrical cavity; the tail end of each screw is arranged at one end of the corresponding lever and the other end of each lever props against the bottom of the cylinder. According to the device, the height of the workpiece is adjusted by rotating the screws so that the surface of the testing workpiece is horizontal and the accuracy of a final testing result is ensured.

Description

Technical field [0001] The invention relates to a height adjustment device, in particular to a device that can adjust the level of a test workpiece. Background technique [0002] In the field of machining, the test body is often given a force to slide in the catheter and impact the surface of the workpiece at a certain speed and then rebound, and then calculate the hardness of the workpiece surface based on the impact and rebound speed. But in real life, because the surface shape of the tested workpiece is not necessarily horizontal, when the test body impacts the surface of the workpiece at a certain speed, the surface of the workpiece bounces back and cannot rebound in the vertical direction, which makes the final test result error. Summary of the invention [0003] In order to solve the defect of inaccurate test results caused by the non-level surface of the workpiece, the present invention provides a device that can adjust the level of the test workpiece. [0004] The technical...
