Description

Technical Field

[0001] This utility model relates to the field of compressor assembly technology, and in particular to a positioning fixture for the compressor drive end. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it by driving a piston through the operation of a motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle.

[0003] Most compressors on the market have a drive shaft. The installation of the drive shaft requires positioning. Some drive shaft installations involve fixing the drive shaft and then assembling it. However, most existing drive shaft clamps are fixed, which makes it difficult to adapt to housings of different heights, resulting in limitations of the clamps. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning fixture for the compressor drive end.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning fixture for a compressor drive end includes a base, a support frame fixedly connected to the upper surface of the base, an open sliding hole in the support frame, a threaded tube slidably connected in the sliding hole, a connecting block fixedly connected to the top of the threaded tube extending out of the sliding hole, a second elastic bracket for placing a drive shaft fixedly connected to the top of the connecting block, a lead screw threadedly connected in the threaded tube, a throttle fixedly connected to the bottom of the lead screw, and the throttle extending out of the support frame, a guide assembly for vertical movement of the connecting block provided on the top of the support frame, a connecting frame fixedly connected to one side of the connecting block, a sliding opening on one side of the connecting frame, a slide rail slidably connected in the sliding opening, a first elastic bracket fixedly connected to the top of the slide rail, and an insertion assembly for fixing the slide rail provided on one side of the connecting frame.

[0007] As a further embodiment of this utility model, the guide component includes a slide groove, which is formed on the top of the support frame. A slider is slidably connected in the slide groove, and a connecting plate is rotatably connected to the top of the slider. The connecting plate is rotatably connected to the connecting block.

[0008] As a further embodiment of this utility model, the insertion assembly includes a positioning hole, which is opened on one side of the slide and penetrates through the slide. A bracket is inserted into the positioning hole and passes through the connecting frame. A insertion hole is opened on one side of the slide, and the bracket is inserted into the insertion hole.

[0009] As a further improvement of this invention, a rubber ring is fixedly connected to the outer side of the socket located inside the socket hole.

[0010] As a further improvement of this utility model, two limiting rings are fixedly connected to the outer side of the slide, so that the limiting rings block and limit the slide.

[0011] As a further embodiment of this invention, a pad frame for placing the compressor housing is fixedly connected to the top of the base.

[0012] As a further improvement of this utility model, the base is fixedly connected to support legs at the four corners of its bottom.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model is equipped with a lead screw and a threaded tube. When the lead screw is rotated, the threaded engagement between the lead screw and the threaded tube will cause the threaded tube to push the connecting block upward, thereby changing the height of the drive shaft. This makes it easier for the drive shaft to match the compressor housing of different heights, thus improving the effectiveness of the positioning fixture.

[0015] 2. By providing an engagement assembly, this utility model can fix the slide after the drive shaft is positioned and placed, thereby ensuring stable placement of the drive shaft and improving the stability of the positioning fixture.

[0016] 3. By providing a limiting ring, this utility model can prevent the slide from separating from the connecting frame during the movement of the slide, and at the same time facilitate the alignment of the positioning hole and the insertion hole, thus improving the convenience of using the positioning fixture.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3 A positioning fixture for a compressor drive end includes a base 1, a support frame 2 welded to the upper surface of the base 1, an open sliding hole in the support frame 2, a threaded tube 5 slidably connected within the sliding hole, a connecting block 11 welded to the top of the threaded tube 5 extending out of the sliding hole, a second elastic bracket 10 for placing a drive shaft welded to the top of the connecting block 11, a lead screw 12 threadedly connected within the threaded tube 5, a throttle 6 welded to the bottom end of the lead screw 12, and the throttle 6 extending out of the support frame 2, a guide assembly for vertically moving the connecting block 11 provided at the top of the support frame 2, a connecting frame 7 welded to one side of the connecting block 11, a sliding opening on one side of the connecting frame 7, a slide 8 slidably connected within the sliding opening, a first elastic bracket 9 welded to the top of the slide 8, and an engagement assembly for fixing the slide 8 on one side of the connecting frame 7, so that the engagement assembly no longer... The slide 8 is fixed, and pulling the slide 8 moves it. The slide 8 will drive the first elastic bracket 9 to move, thereby misaligning the first elastic bracket 9 with the second elastic bracket 10. Then, the drive shaft is placed in the second elastic bracket 10, and then the slide 8 is pulled back to reset, so that the drive shaft is locked in the first elastic bracket 9 for positioning. By turning the throttle 6, the lead screw 12 is rotated. The lead screw 12 engages with the threaded tube 5, which pushes the connecting block 11 upward. The connecting block 11 will drive the connecting frame 7 upward, and the connecting frame 7 will drive the slide 8 upward. This will cause the first elastic bracket 9 and the second elastic bracket 10 to move upward, thereby driving the drive shaft upward and changing the height of the drive shaft. This makes it easier for the drive shaft to match the compressor housing of different heights, improving the effectiveness of the positioning fixture.

[0023] In this utility model, the guide component includes a slide groove 13, which is opened on the top of the support frame 2. A slider 4 is slidably connected in the slide groove 13. A connecting plate 14 is rotatably connected to the top of the slider 4, and the connecting plate 14 is rotatably connected to the connecting block 11. When the connecting block 11 moves upward, it will drive the slider 4 to move along the slide groove 13 through the connecting plate 14. At the same time, the connecting plate 14 will rotate with the slider 4 and the connecting block 11, thereby causing the connecting block 11 to move vertically upward.

[0024] Specifically, the mating assembly includes a positioning hole 17, which is located on one side of the slide 8 and extends through the slide 8. A insert 19 is inserted into the positioning hole 17 and passes through the connecting bracket 7. A insertion hole 15 is provided on one side of the slide, and the insert 19 is inserted into the insertion hole 15. Pulling the insert 19 moves it, causing it to disengage from the insertion hole 15 and be pulled out of the positioning hole 17. At this time, the slide 8 can be moved. When the slide 8 returns to its original position, the positioning hole 17 will be aligned with the insertion hole 15. Then, the insert 19 is inserted through the positioning hole 17 into the insertion hole 15 to fix the position of the slide 8, thus stabilizing the drive shaft. A rubber ring 16 is glued to the outside of the insert 19 inside the socket 15. The rubber ring 16 can increase the friction between the insert 19 and the connecting frame 7, so that the insert 19 can be stably inserted into the socket 15. Two limiting rings 18 are welded to the outside of the slide 8, so that the limiting rings 18 can block and limit the slide 8. One limiting ring 18 can prevent the slide 8 from separating from the connecting frame 7, while the other limiting ring 18 can position and reset the slide 8, making it easy to align the positioning hole 17 with the socket 15. The top of the base 1 is fixed with a pad frame 3 for placing the compressor housing by bolts. The bottom of the base 1 is fixed with support legs at the four corners by bolts.

[0025] Working principle: When needed, pull the insert 19 to move it, disengaging it from the socket 15 and pulling it out of the positioning hole 17. Then, the slide 8 can be moved within the sliding groove. The slide 8 will move the first elastic bracket 9, causing it to misalign with the second elastic bracket 10. The drive shaft is then placed in the second elastic bracket 10. Pulling the slide 8 back to its original position allows the drive shaft to engage with the first elastic bracket 9. At this point, the positioning hole 17 aligns with the socket 15, thus positioning the drive shaft. The insert 19 is then inserted through the positioning hole 17 into the socket 15 to fix the position of the slide 8. Finally, the screw 1 is rotated by the throttle 6. 2. The lead screw 12 engages with the threaded tube 5, causing the threaded tube 5 to push the connecting block 11 upward. The connecting block 11 then drives the connecting frame 7 upward, which in turn drives the slide 8 upward. This causes the first elastic bracket 9 and the second elastic bracket 10 to move upward, thus driving the drive shaft upward. During the upward movement of the connecting block 11, the connecting plate 14 drives the slider 4 to move along the slide groove 13. At the same time, the connecting plate 14 rotates with the slider 4 and the connecting block 11, causing the connecting block 11 to move vertically upward. This changes the height of the drive shaft, making it easier for the drive shaft to match the compressor housing of different heights, thus improving the effectiveness of the positioning fixture.

[0026] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
