[0001] This utility model belongs to the field of product testing technology, and in particular relates to a position detection disc. Background Technology

[0002] Currently, the method for detecting the position of grooves and lug holes on the bottom surface of products to be inspected is coordinate measuring machine (CMM). When inspecting some grooves and holes with low position accuracy requirements, it takes a long time to select several points on the workpiece for each product to be inspected, and sometimes it cannot meet the inspection frequency requirements of some parts. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a testing disc that can significantly shorten the detection time of the bottom groove and ear hole position of the product to be tested.

[0005] Preferably, the positioning surface of the outer positioning retaining ring is set as an arc surface structure with the outer side higher than the inner side, the outer edge of the top surface of the test block is set as an oblique angle structure, and the top surface of the positioning post is set as a spherical structure.

[0006] Preferably, the system also includes a lifting and rotating mechanism, which consists of a telescopic cylinder, a support plate, a rotating platform, and a lifting cone. The cylinder body of the telescopic cylinder is fixedly mounted on the base, the support plate is slidably mounted on the column, the detection plate has a through hole coaxial with the outer positioning retaining ring, the fixed platform at the bottom of the rotating platform is fixedly mounted on the support plate, the rotating platform is coaxial with the through hole, and the lifting cone is fixedly mounted on the upper rotating body of the rotating platform, the lifting cone is coaxial with the rotating platform, and both the rotating platform and the lifting cone can pass through the through hole.

[0007] Preferably, a guide sleeve is fixedly installed on the pallet, and the guide sleeve is slidably fitted onto the column.

[0008] Compared with the prior art, the advantages of this utility model are: this testing plate can quickly detect the position of the groove on the bottom surface and the hole on the lug of the product to be tested. For products with large mass, the angle of the product to be tested can be adjusted after supporting it with a lifting cone, which reduces the difficulty for operators to rotate large mass products to be tested. The lifting cone has the advantage of wide applicability and can meet the support requirements of products with various center hole sizes. When changing to products of different sizes and types, only the testing plate corresponding to the product to be tested needs to be replaced. Attached Figure Description

[0012] Figure 3 This is a 3D view of the product to be tested. Detailed Implementation

[0013] The present invention will now be described in detail with reference to specific embodiments:

[0014] like Figures 1 to 3 The position detection disk shown includes a base 1, a top plate 2, columns 3 and a detection disk 4. Four columns 3 are fixedly installed on the base 1 in a rectangular arrangement. The detection disk 4 is fixedly installed on the top of the columns 3. The top surface of the detection disk 4 is provided with an outer positioning retaining ring 41 arranged in a ring array. The top surface of the detection disk 4 is provided with a test block 42 coaxial with the outer positioning retaining ring 41 arranged in a ring array. The detection disk 4 is also provided with positioning posts 43.

[0015] The positioning surface of the outer positioning retaining ring 41 is set as an arc surface structure with the outer side higher than the inner side. The outer edge of the top surface of the test block 42 is set as an angled structure. The top surface of the positioning post 43 is set as a spherical structure so that the outer surface of the product to be tested 10 can be embedded into the outer positioning retaining ring 41. The bottom groove 101 is embedded into the test block 42, and the hole 102 on the lug is embedded into the positioning post 43 to play a guiding role. During the test, the outer positioning retaining ring 41, the test block 42, and the positioning post 43 serve as the positioning reference for the product to be tested 10, which can greatly shorten the test speed of the product to be tested 10 with low position accuracy requirements.

[0016] It also includes a lifting and rotating mechanism, which consists of a telescopic cylinder 5, a support plate 6, a rotating platform 7, and a lifting cone 8. The cylinder body of the telescopic cylinder 5 is fixedly mounted on the base 1. The support plate 6 is slidably mounted on the column 3. The detection disc 4 is provided with a through hole 20 coaxial with the outer positioning retaining ring 41. The fixed platform at the lower part of the rotating platform 7 is fixedly mounted on the support plate 6. The rotating platform 7 is coaxial with the through hole 20. The lifting cone 8 is fixedly mounted on the upper rotating body of the rotating platform 7. The lifting cone 8 is coaxial with the rotating platform 7. Both the rotating platform 7 and the lifting cone 8 can pass through the through hole 20. The piston rod of the telescopic cylinder 5 extends and pushes the support plate 6, the rotating platform 7, and the lifting cone 8 upward. The center hole of the product 10 to be tested is fitted onto the lifting cone 8. The rotating platform 7 is adjusted... When the angle of the product to be tested 10 is adjusted, the piston rod of the telescopic cylinder 5 retracts, causing the support plate 6, the rotating table 7, and the lifting cone 8 to move downwards. When the bottom groove 101 of the product to be tested 10 is about to fit into the test block 42, the piston rod of the telescopic cylinder 5 stops retracting and the angle of the product to be tested 10 is rotated and finely adjusted again. Then the piston rod of the telescopic cylinder 5 continues to retract, and the outer surface of the product to be tested 10 is embedded in the outer positioning retaining ring 41, its bottom groove 101 is embedded in the test block 42, and the hole 102 on its hanging ear is embedded in the positioning post 43. If the product to be tested 10 does not wobble, then the product to be tested 10 is a qualified product. The piston rod of the telescopic cylinder 5 extends again to push the support plate 6, the rotating table 7, and the lifting cone 8 to move upwards. The lifting cone 8 pushes the product to be tested 10 off the test plate 4 and removes it.

[0017] A guide sleeve 61 is fixedly installed on the pallet 6. The guide sleeve 61 is slidably fitted onto the column 3. The guide sleeve 61 improves the straightness of the pallet 6 when it moves up and down.
