[0082] Embodiment 8:

[0083] This embodiment provides a processing fixture for a vacuum pump housing. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0084] Installation feet 26 are provided at both ends of the base 1, and two groups of installation holes 27 are opened on the installation feet 26, and threads are provided on the inner ring of each installation hole 27.

[0086] Working principle: First, place the vacuum pump housing on the carrier table 25 and the two clamping seats 7. Start the two driving cylinders 6 to drive the two moving blocks 5 to move. The moving blocks 5 drive the clamping seats 7 and the clamping plates 8 to move, so as to clamp the length of the vacuum pump housing. At this time, rotate the first threaded rod 10 to drive the clamping block 11 to move, so as to clamp the width of the vacuum pump housing. Then move the pressing plate 14 downward to abut against the surface of the vacuum pump housing, and then rotate the nut 15 to press the pressing plate 14, so as to fix the height of the vacuum pump housing.

[0087] When it is necessary to replace the abutting plates 19 of different shapes, they can be pushed inward along the card slots 24, so as to push the card blocks 22 into the installation slots 20, so that the card blocks 22 are no longer engaged with the card slots 24. Then the abutting plates 19 are pulled out from the limiting blocks 18. During installation, slide the abutting plates 19 downward and sleeved on the outside of the limiting blocks 18, so that the cross section of the card blocks 22 is squeezed, so that the card blocks 22 move into the installation slots 20, and the springs 23 and the telescopic rods 21 are compressed. Thus, when the abutting plates 19 are completely sleeved on the limiting blocks 18, the installation slots 20 are aligned with the card slots 24, so that the card blocks 22 are no longer squeezed. Therefore, through the restoring force when the springs 23 rebound, and in cooperation with the telescopic rods 21, the card blocks 22 move outward along the installation slots 20, so as to be engaged in the card slots 24, completing the limiting of the abutting plates 19. The installation and disassembly are simple, and the practicability of the structure is high.
