Description

Technical Field

[0001] This utility model relates to the field of hole position detection technology, and more specifically, to a vortex stationary disk hole position detection fixture. Background Technology

[0002] The scroll stationary disc is the core stationary component of the scroll compressor. It is a disc-shaped metal part with scroll-shaped lines machined on its end face, as well as bolt holes and positioning holes distributed for installation and fixing. The scroll stationary disc hole position detection fixture is a special inspection tool. It fixes the stationary disc through a positioning mechanism and uses a vision sensor or contact probe to automatically and quickly measure the position, diameter and other key dimensions of these mounting holes.

[0003] The existing vortex stationary disk hole position detection fixture typically requires a standard detection assembly plate with locating pins installed on it, and a detection unit mounted on the locating pins. The hole position of the stationary disk is detected by using the pre-set locating pins. However, the hole position changes for different specifications of stationary disks, so the fixture is not applicable and a pre-matched detection assembly plate and locating pins need to be prepared and reassembled. This results in limited applicability, the need for disassembly and replacement for different specifications, cumbersome operation, and poor performance. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, this utility model provides a vortex stationary disk hole position detection fixture, including a base 1, a stationary disk fixing mechanism 8 fixedly mounted on the top of the base 1, an assembly frame 3 above the stationary disk fixing mechanism 8, detachable detection assembly plates 4 evenly spaced on the outer side of the assembly frame 3, an assembly hole on the front of the detection assembly plate 4, mounting connectors 5 fixedly connected to both sides of the assembly frame 3, a support plate 6 sleeved on the outer side of the mounting connectors 5, a positioning mechanism 7 fixedly mounted on the front of the support plate 6, the positioning mechanism 7 limiting the position of the mounting connectors 5, and an electric push rod 2 fixedly connected to the top of the base 1, the free end of the electric push rod 2 fixedly connected to the support plate 6.

[0024] The assembly frame 3 has a stepped groove 12 on its outer side. The inspection assembly plate 4 is movably sleeved in the stepped groove 12. One end of the assembly frame 3 is threaded with a locking bolt 13. The inspection assembly plate 4, which is sleeved in the stepped groove 12, is clamped and fixed by the locking bolt 13. A positioning pin is fixedly installed in the assembly hole, and the end of the positioning pin is provided with an inspection unit.

[0025] The stepped groove 12 enables the positioning and fitting of the inspection assembly plate 4, which is then locked in place with the locking bolt 13, facilitating disassembly and replacement.

[0026] The mounting connector 5 includes a connecting plate 51, a connecting shaft 52, a rotating disk 53, and a slot 54. The connecting plate 51 is fixed inside the assembly frame 3, the connecting shaft 52 is fixed on the front of the connecting plate 51, the rotating disk 53 is fixedly sleeved on the outer surface of the connecting shaft 52, and the slots 54 are equally spaced around the rotating disk 53. The number of slots 54 is the same as the number of detection assembly plates 4. The positioning mechanism 7 includes an assembly ring 71, a bottom sleeve 72, an assembly cavity 73, an electromagnet 74, a locking block 75, and a spring 76. The assembly ring 71 is fixed on the front of the support plate 6 and sleeved on the outside of the rotating disk 53. The bottom sleeve 72 is fixedly connected to the bottom of the assembly ring 71. The assembly cavity 73 is opened on the inner wall of the assembly ring 71 and communicates with the bottom sleeve 72. The electromagnet 74 is fixedly installed inside the bottom sleeve 72. The spring 76 is fixed in the bottom sleeve 72 through the support frame connected to the bottom. The upper end of the spring 76 is fixedly connected to the locking block 75, and the locking block 75 is located on the rotation path of the slot 54.

[0027] By installing the connector 5 and cooperating with the positioning mechanism 7, the rotating disk 53 is driven to rotate when the connecting shaft 52 rotates. The positioning of the rotating disk 53 is achieved through the cooperation of the locking block 75 and the locking slot 54, maintaining stability after rotation adjustment. Different inspection assembly plates 4 can be easily switched to achieve different specifications of inspection.

[0028] The stationary plate fixing mechanism 8 includes a fixed curved plate 81, a positioning sleeve 82, and a positioning groove 83. The fixed curved plates 81 are symmetrically distributed on the top of the base 1. The positioning sleeve 82 is fixedly connected between the two sets of fixed curved plates 81. The positioning groove 83 is opened on the top of the positioning sleeve 82. A locking rod is threaded onto the outer side of the positioning sleeve 82.

[0029] The stationary plate fixing mechanism 8 clamps and fixes the stationary plate under test, maintaining stable testing.

[0030] The base 1 has an air supply component 11 on its top, and a purge pipe 9 is symmetrically arranged on the back of the support plate 6. The support plate 6 has a through hole 10 inside, which is connected to the purge pipe 9. The air outlet of the purge pipe 9 is inclined towards the top of the stationary plate fixing mechanism 8. The air supply component 11 includes a distribution frame 111, an air pump 112, and a connecting pipe 113. One end of the connecting pipe 113 is connected to the through hole 10, and the other end of the connecting pipe 113 is connected to the distribution frame 111. The air outlet of the air pump 112 is connected to the distribution frame 111.

[0031] Powered air is output through the air supply component 11, and in conjunction with the outlet through the through hole 10 and the purge pipe 9, the stationary plate is cleaned by blowing, thus avoiding interference from impurities in the hole at the top of the stationary plate.

[0032] The working principle and usage process of this utility model are as follows: In use, the stationary disc to be tested is placed in the positioning sleeve 82 of the stationary disc fixing mechanism 8 and positioned in the positioning groove 83. The locking rod is rotated to lock and fix it. For the specific stationary disc model to be tested, the positioning mechanism 7 is activated, the electromagnet 74 is energized and generates magnetic attraction, magnetically moving the locking block 75 downwards, releasing the locking block 75 from the locking groove 54, pushing the assembly frame 3 to flip. As the connecting shaft 52 in the mounting connector 5 rotates in the support plate 6, the corresponding matching testing assembly plate 4 flips to the desired orientation, and the positioning pin and testing unit installed on it flip to the desired orientation simultaneously. The positioning mechanism 7 is then closed, the electromagnet 74 is de-energized, and the locking block 75, losing its magnetic attraction, is elastically released by the spring 76. Reset and move the sleeve upward into the slot 54. After rotation, fix it. When testing, start the electric push rod 2 to drive the support plate 6 to move downward, and drive the assembly frame 3 and the testing assembly plate 4 to move downward, so that the testing units on the positioning pin face the holes on the stationary plate one by one. The probes and vision units in the testing units perform hole position detection. When testing, as the support plate 6 moves the assembly frame 3 downward, the air supply component 11 is started simultaneously. The air pump 112 inputs pressurized air into the through hole 10 through the distribution frame 111 and the connecting pipe 113, and blows it out through the blow pipe 9 to clean the top hole of the stationary plate to be tested. As the support plate 6 moves downward, the blowing range of the blow pipe 9 changes to achieve cleaning of each group of holes.
