Embodiment 1

[0032] as attached figure 1 As shown, an adaptive positioning device for hardness testing of workpieces can locate the handwheel position of the starting point of the pressure test of the first workpiece when the hardness testing of a large number of workpieces is performed, and then when the hardness testing of the same batch of workpieces is performed subsequently, Quickly find out the position of the hand wheel to carry out the test work, and solve the problems of low test efficiency and low precision in the existing method of manually adjusting the starting point of the pressure test.

[0033] An adaptive positioning device for workpiece hardness detection, comprising: an adjustment wheel, a limiter and a positioning member; the adjustment wheel is connected to at least one limiter, and the positioning member is fixedly arranged in the direction of movement of the adjustment wheel; The limiting member includes an elastic body with a pre-tightening force, and the elastic bo...

Embodiment approach

[0037] The adjusting wheel is a hand wheel, and the hand wheel includes a center wheel connected with the transmission mechanism and several rods connected with the center wheel. The several rods are arranged radially in equal parts around the center wheel, and the second hollow tube and The rod of the handwheel is socketed, and the cross-section of the rod is circular, square or polygonal; the cross-section of the second hollow cylinder is the same as that of the rod. The transmission mechanism includes but not limited to a screw transmission mechanism, a rack and pinion mechanism, a slider linkage mechanism and a cam mechanism. As a preferred embodiment, the transmission mechanism is a screw transmission mechanism.

[0038] The locating member includes a chassis and a locating block, the chassis has a locating groove, and the locating groove is a groove structure arranged along the direction of the arc; For installing the positioning block, the positioning block is slidably ...

Embodiment 2

[0042] An adaptive positioning device for hardness testing of workpieces, mainly including push rods, cages, springs, handwheels, positioning blocks and bases. When testing the hardness of large quantities of workpieces, the positioning blocks on the bases can The position of the handwheel, and then when the same batch of workpieces are tested later, the position of the handwheel can be quickly found by fixing the position of the push rod and the positioning block, that is, the pressurized test point of the workpiece, thus saving the time of adjusting the handwheel and greatly Improved testing efficiency.

[0043] A circular sliding groove is provided on the 1 / 4 area of ​​the base, and the circular sliding groove is used to place and limit the positioning block, and the position of the positioning block can be fixed by locking the sliding groove.

[0044] The spring is placed in the middle of the push rod and the hand wheel, and is used for moving and positioning up and down i...

Abstract

The invention provides a self-adaptive positioning device and a self-adaptive positioning system for workpiece hardness detection, and methods. The self-adaptive positioning device comprises an adjusting wheel, limiting pieces and a positioning piece. The adjusting wheel is connected with at least one limiting piece, and the positioning piece is fixedly arranged in the moving direction of the adjusting wheel. Each limiting piece comprises an elastic body with A pre-tightening force, and the elastic body with the pre-tightening force released can be matched with the positioning piece to achievepositioning. The problems that when large-batch workpiece detection is conducted, a hand wheel needs to be manually rocked to adjust the starting point of a pressurization test in each test, time andlabor are wasted and the test efficiency is low are solved, and the effects of greatly saving the test time, improving the test efficiency and being suitable for hardness detection of large-batch workpieces are achieved; and the self-adaptive positioning device is high in practicability and can be flexibly disassembled, assembled and maintained, and the test cost is greatly reduced.

Description

technical field [0001] The present disclosure relates to the field of mechanical parts, in particular to an adaptive positioning device, system and method for workpiece hardness detection. Background technique [0002] In order to ensure the quality of production, enterprises will test the mechanical properties of products before leaving the factory, and hardness testing is a convenient method to test the mechanical properties of workpieces. Due to the advantages of small indentation, simple operation and high testing efficiency, the Rockwell hardness tester is widely used in the detection of workpiece hardness. Its test principle is, under specified conditions, firstly lift the sample placed on the anvil to the position where it is in contact with the indenter by shaking the handwheel, and then slowly shake the handwheel until the small pointer on the dial approaches Vertical position, this is the starting point of the pressure test; then turn down the crank clockwise, app...
