[0002] Existing pressure sensor assembly fixtures, despite their structural design, are unsuitable for assembling most pressure sensors. Furthermore, during assembly, misalignment of components can easily occur, affecting the sensor's yield rate. For example, Chinese patent CN202121516343.5 discloses a fixture for assembling invasive pressure sensors, comprising a base, a positioning seat for placing a top cover, a first mounting seat for placing a three-way valve, and a second mounting seat for placing a flushing valve. The positioning seat is designed with... It is placed between the first mounting base and the second mounting base, both of which are slidably connected to the base towards the positioning seat. The first mounting base can drive the three-way valve to slide to the first insertion position, and the second mounting base can drive the flushing valve to slide to the second insertion position. With the above structure, it is easy to use. However, it is not suitable for assembling most pressure sensors. During assembly, the various parts are prone to misalignment due to non-concentricity and coaxiality, which affects the pass rate of the pressure sensor and limits its use. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5This utility model embodiment of a pressure sensor assembly fixture includes: a support plate 1, a worktable 2 fixedly connected to the upper surface of the support plate 1, a sliding column 14 slidably connected to the worktable 2, a hydraulic cylinder 19 fixedly connected to the lower surface of the worktable 2, the output end of the hydraulic cylinder 19 fixedly connected to the sliding column 14, a receiving groove provided on the sliding column 14, a sleeve rod 22 provided in the receiving groove, a rotating bar 26 fixedly connected to the side surface of the sleeve rod 22, the rotating bar 26 located on the upper surface of the sleeve rod 22, another receiving groove provided on the sleeve rod 22, a movable rod 23 provided in the other receiving groove, a rotating bar 15 fixedly connected to the side surface of the movable rod 23, the rotating bar 15 located above the rotating bar 26, the rotating bar 15 and the rotating bar 26 being connected to the rotating bar 23. Suction blocks 21 are provided on the lower surface of each of the two components 16. An air pump 34 is fixedly connected to the lower surface of the worktable 2. The input end of the air pump 34 is connected to the suction block 21 through an air pipe. A clamping assembly is provided on the upper surface of the worktable 2. A baffle 9 is provided on the side surface of the worktable 2. A bolt 8 is provided on the side surface of the baffle 9. The bolt 8 passes through the baffle 9 and is threadedly connected to the worktable 2. A fixing block 11 is fixedly connected to the upper surface of the baffle 9. A threaded rod 10 is threadedly connected to the fixing block 11. A connecting block 12 is fixedly connected to the end of the threaded rod 10 away from the baffle 9. A limit plate 13 is slidably connected to the worktable 2. A sliding groove is provided on the worktable 2. A slider 26 is slidably connected in the sliding groove. The slider 26 is fixedly connected to the lower surface of the limit plate 13.

[0024] Specifically, after clamping the pressure sensor housing with the clamping assembly, different parts are placed under the corresponding suction blocks 21. The air pump 34 is used to make the suction blocks 21 adsorb and fix the parts. Since multiple fixing strips 15 and 16 can be set, when different fixing strips are rotated, the suction blocks 21 on them are rotated to be directly above the placement groove 25. By rotating the threaded rod 10, the connecting block 12 is moved, which pushes the limiting plate 13 to move on the worktable 2. Under the action of the slider 26 and the slide groove, it is limited and fits against the side surface of the fixing strip to limit it, so that the subsequent assembly work can be carried out.

[0025] The clamping assembly includes a support block 3, which is fixedly connected to the side surface of the worktable 2. A cylinder 4 is fixedly connected to the upper surface of the support block 3, and a C-shaped block 5 is fixedly connected to the output end of the cylinder 4. A rotating column is provided on the C-shaped block 5, and a connecting plate 6 is provided on the inner side of the C-shaped block 5. The rotating column passes through the connecting plate 6 and extends to the lower surface of the connecting plate 6. A limit ring 31 is fixedly connected to the upper surface of the worktable 2, and a rotating plate 33 is rotatably connected to the outer side of the limit ring 31. The connecting plate 6 is fixedly connected to the side surface of the rotating plate 33, and a movable groove 32 is provided on the rotating plate 33. A movable column 27 is provided in the movable groove 32, and a clamping block is fixedly connected to the upper surface of the movable column 27. 28. A fixing strip 17 is fixedly connected to the upper surface of the worktable 2. A fixing plate 18 is fixedly connected to the side surface of the fixing strip 17. A limiting groove 29 is provided on the side surface of the fixing plate 18. A limiting block 30 is slidably connected in the limiting groove 29. The limiting block 30 is fixedly connected to the side surface of the clamping block 28. A placement groove 25 is provided on the worktable 2. A support plate 24 is slidably connected in the placement groove 25. An electric push rod 20 is fixedly connected to the lower surface of the worktable 2. The output end of the electric push rod 20 is fixedly connected to the lower surface of the support plate 24. A control panel 7 is fixedly connected to the upper surface of the worktable 2. The control panel 7 is electrically connected to the cylinder 4, the electric push rod 20, and the air pump 34.

[0026] Specifically, the electric push rod 20 drives the support plate 24 to rise, lifting the housing. When the cylinder 4 works, it drives the C-shaped block 5 to move. Since the C-shaped block 5 is rotatably connected to the connecting plate 6, and the connecting plate 6 is fixedly connected to the side surface of the rotating plate 33, the rotating plate 33 can rotate around the limiting ring 31 under the action of the limiting ring 31. Since the limiting groove 29 is set on the fixed plate 18, and the fixed plate 18 is fixedly connected to the worktable 2 by the fixing strip 17, when the rotating plate 33 rotates, the movable column 27 moves in the movable groove 32. Through the rotation of the rotating plate 18, the movable column 27 drives the clamping block 28 to move when it moves. The limiting groove 29 limits the clamping block 28, so that the clamping block 28 can only move back and forth. The control panel 7 controls the electronic components.

[0027] Working principle: In use, the pressure sensor housing is placed in the placement groove 25. The cylinder 4 operates, driving the C-shaped block to move, causing the rotating plate 33 to rotate, which in turn moves the clamping block 28 to clamp and fix the housing. Then, each part is placed on the suction block set on the rotating bar 15 or rotating bar 26. When the air pump 34 is working, the parts are sucked up and installed one by one. During installation, since there can be multiple sleeve rods 22 and movable rods 23, the parts on the outermost sleeve rod 22, that is, the parts on the bottom rotating bar 15, are installed first. Rotate them to the top of the placement groove 25. Since the suction block 21 is exactly on the axis of the placement groove 25, by rotating the threaded rod 10, the limiting plate 13 is made to fit with the side surface of the rotating bar 15 to limit it and prevent it from rotating. Then, the hydraulic cylinder 19 drives the sliding column 14 to descend, so that the parts can be placed on the pressure sensor housing for concentric and coaxial installation.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
