Description

Technical Field

[0001] This utility model relates to the field of bearing testing tooling technology, and in particular to a thrust bearing height testing mechanism. Background Technology

[0002] Thrust bearings are special bearings designed to withstand axial forces. When inspecting the height of thrust bearing products, measurements must be taken under standard pressure.

[0003] Existing presses generally come with a built-in height detection function, but in practical applications, it has been found that the height detection module of the press is not accurate enough, resulting in inaccurate detection results. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a thrust bearing height detection mechanism that is convenient for clamping and positioning, has high measurement accuracy, and can effectively guarantee the product qualification rate.

[0005] This utility model is achieved through the following technical solution: a thrust bearing height detection mechanism, including a press and a height detection device. The press is used to apply standard pressure for height detection to the thrust bearing product to be tested, and has a liftable pressure head and a base corresponding to the pressure head. The height detection device is disposed on the base and is used to detect the height of the product.

[0006] To achieve simple and efficient height detection of thrust bearing products in conjunction with a press, while improving measurement accuracy, the height detection device includes a height standard block and a load-bearing platform, a positioning mandrel, and an upper pressure block arranged coaxially from bottom to top. The height standard block is designed and manufactured according to the upper and lower limit dimensions of the product, and has two ends with different thicknesses, namely the upper limit dimension measuring part and the lower limit dimension measuring part, respectively. The upper limit dimension measuring part corresponds to the upper limit dimension of the product height, and the lower limit dimension measuring part corresponds to the lower limit dimension of the product height. The positioning mandrel is sleeved inside the load-bearing platform and is used in conjunction with the load-bearing platform to place and position the product to be tested. The upper pressure block is annular, sleeved outside the positioning mandrel, and presses against the product.

[0007] To ensure more uniform pressure on the product under test, thereby guaranteeing measurement accuracy and facilitating the measurement of the height standard block, the upper pressure block is fitted with the positioning mandrel with a clearance, and the outer diameter of the upper pressure block is larger than the outer diameter of the product.

[0008] To improve the stability and positioning accuracy of the clamping and positioning, and to further ensure the measurement accuracy, the load-bearing platform is provided with a mandrel connection hole, and the positioning mandrel is interference-fitted into the mandrel connection hole.

[0009] Preferably, the inner diameter surface of the upper pressure block is provided with several locking clearance grooves to avoid the locking of the thrust bearing product.

[0010] The beneficial effects of this utility model are as follows: This thrust bearing height detection mechanism, by designing a height standard block with two measuring ends and using it in conjunction with a press, achieves simple and efficient height detection of thrust bearing products, replacing the existing technology of directly detecting product height with a press, greatly improving detection accuracy and ensuring product qualification rate; in addition, this thrust bearing height detection mechanism has high positioning accuracy, simple structure, and low cost.

Detailed Implementation

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0018] like Figure 1-3 The thrust bearing height detection mechanism shown includes a press 1 and a height detection device 2. The press 1 has a liftable pressure head 11 and a base 12 corresponding to the pressure head 11. The height detection device 2 is mounted on the base 12 and includes a height standard block 21 and a support platform 22, a positioning spindle 23, and an upper pressure block 24 arranged coaxially from bottom to top. Figure 5 As shown, the height standard block 21 has two ends with different thicknesses, namely an upper limit dimension measuring part 211 and a lower limit dimension measuring part 212. The upper limit dimension measuring part 211 corresponds to the upper limit dimension of the product height, and the lower limit dimension measuring part 212 corresponds to the lower limit dimension of the product height.

[0019] like Figure 4 As shown, the support platform 22 has a spindle connection hole 221, and the positioning spindle 23 is interference-fitted into the spindle connection hole 221 of the support platform 22.

[0020] The upper pressure block 24 is annular, sleeved on the positioning mandrel 23 and pressing against the product 9. The upper pressure block 24 and the positioning mandrel 23 are in clearance fit, and the outer diameter of the upper pressure block 24 is larger than the outer diameter of the product 9. Several locking clearance grooves 241 are formed on the inner diameter surface of the upper pressure block 24.

[0021] The process of using this thrust bearing height detection mechanism to perform height detection on thrust bearing product 9 is as follows:

[0022] First, place the product 9 to be tested on the load-bearing platform 22 through the positioning mandrel 23. Then, place the upper pressure block 24 through the positioning mandrel 23 and press it onto the upper surface of the product 9. Next, start the press machine 1. The pressure head 11 descends onto the upper pressure block 24 and applies pressure to the upper pressure block 24, thereby applying pressure to the product 9 to the preset standard pressure.

[0023] Finally, a height test is performed. Select the height standard block 21 corresponding to product 9. First, insert one end of the lower limit dimension measuring part 212 between the upper pressure block 24 and the support platform 22. If it cannot be inserted, the height is judged to be below the standard range, and product 9 is judged to be unqualified. If it can be inserted, insert one end of the upper limit dimension measuring part 211 between the upper pressure block 24 and the support platform 22. If it can be inserted, the height is judged to be above the standard range, and product 9 is judged to be unqualified. If it cannot be inserted, product 9 is judged to be qualified.
