[0001] This invention relates to the field of valve body machining technology, specifically to a multi-position valve body turning device for automotive air conditioning compressor control valves. Background Technology

[0002] In the manufacturing process of automotive air conditioning compressors, the machining accuracy of the control valve has a crucial impact on the performance of the entire system. As the core component of the control valve, the machining quality of the valve body directly determines the valve's sealing performance, reliability, and service life. Therefore, the turning process of the valve body requires high-precision machining equipment and techniques to ensure its quality.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0023] Please see Figure 1 - Figure 2 This is the first embodiment of the present invention. This embodiment provides a multi-position valve body turning device for automotive air conditioning compressor control valve. Through the structural design of locking components and clamping components, the valve body can be adjusted to different installation heights on this device to meet the multi-position turning work of the valve body.

[0024] Specifically, the device includes: a base 1, a support frame 2 on top of the base 1, a locking component 3 on the support frame 2, a worktable 4 at one end of the locking component 3, a clamping component 5 on top of the worktable 4, and a telescopic component 6 on the side of the worktable 4 away from the clamping component 5.

[0025] Furthermore, the end of the telescopic component 6 away from the workbench 4 is fixedly connected to the base 1 and abuts against the support frame 2, and the support frame 2, the workbench 4, and the telescopic component 6 form a triangle.

[0026] Preferably, the base 1 is provided with mounting slots and mounting holes, enabling the device to be stably mounted on the machine tool. The support frame 2 provides a stable support base for the locking assembly 3 and the clamping assembly 5. The locking assembly 3 is used to adjust the valve body mounting height. The clamping assembly 5 is used to clamp the valve body to be processed. The telescopic assembly 6, through the triangular structure formed by the support frame 2 and the worktable 4, provides a stable frame for the device during operation.

[0027] In use, first place the valve body on the clamping assembly 5. The clamping assembly 5, in conjunction with the worktable 4, securely mounts the valve body on it. When adjusting the installation height, first release the locking assembly 3 from its limit on the support frame 2, allowing it to move up and down. Since the worktable 4 is connected to both the locking assembly 3 and the clamping assembly 5, the clamping assembly 5 also moves under the influence of the locking assembly 3, thus adjusting the valve body's installation height. After adjusting the height, lock the valve body by rotating the locking assembly 3. Simultaneously, release the telescopic assembly 6 to shorten its overall length. After adjusting the installation height, lock the telescopic assembly 6.

[0028] In summary, this multi-position valve body turning device for automotive air conditioning compressor control valves utilizes the structural design of locking and clamping components to allow the valve body to be adjusted to different installation heights on the device, thereby meeting the requirements for multi-position turning operations and greatly improving the working efficiency of the device. Example

[0029] Please see Figure 1 - Figure 8 In the second embodiment of the present invention, unlike the first embodiment, the device further includes: a first sliding groove 21 is provided on the inner side of the support frame 2, ten sets of rectangular frames 22 are fixedly provided on the left and right sides of the first sliding groove 21, a ramp 23 is fixedly provided in each set of rectangular frames 22, a tooth 24 is fixedly provided on the side of each set of rectangular frames 22 away from the ramp 23, and a limit frame 25 is fixedly provided on the outer side of each set of rectangular frames 22.

[0030] Furthermore, the locking assembly 3 includes a slider 31 slidably connected to the first slide groove 21, a connecting shaft 32 fixedly connected to the slider 31, a bearing 33 sleeved on the end of the connecting shaft 32 away from the slider 31, a gear 34 sleeved on the bearing 33, and two sets of tooth blocks 35 meshing with the gear 34; wherein, a limiting groove 351 is provided on the tooth block 35, a first spring 352 is fixedly installed in the limiting groove 351, and the other end of the first spring 352 is connected to an angled block 353.

[0031] Preferably, the bottom of the angular block 353 is provided with teeth, which cooperate with the toothed part 24.

[0032] Furthermore, the locking assembly 3 also includes a wrench 36 fixedly mounted on the gear 34, and two sets of second slide grooves 37 opened on the upper and lower sides of the slider 31; wherein, the two sets of tooth blocks 35 are slidably connected to the two sets of second slide grooves 37 respectively.

[0033] Furthermore, the side of the slider 31 away from the connecting shaft 32 is fixedly connected to the worktable 4; the worktable 4 is provided with a through hole 41.

[0034] In use, first rotate the wrench 36. The wrench 36 drives the gear 34 to rotate, which in turn drives the two sets of toothed blocks 35 to move outward along the two sets of second sliding grooves 37. When the two sets of toothed blocks 35 move outward from the rectangular frame 22, the locking component 3 is released. Then, hold the wrench 36 and move it up and down. The slider 31 will also move within the first sliding groove 21. The side of the slider 31 away from the connecting shaft 32 is connected to the worktable 4, so the slider 31 will drive the worktable 4 to move. The valve body is mounted on the clamping component 5, which is mounted on the worktable 4. The worktable 4 will drive the clamping component 5 to move, thereby adjusting the installation height of the valve body.

[0035] After adjusting the valve body installation height, the locking assembly 3 needs to be locked. First, rotate the wrench 36 in the opposite direction. The wrench 36 drives the gear 34 to rotate, which in turn drives the two sets of toothed blocks 35 to move along the two sets of second sliding grooves 37 into the rectangular frame 22. At this time, the corner blocks 353 on the toothed blocks 35 gradually approach the slope 23. When they come into contact with the slope 23, the corner blocks 353 are squeezed by the slope 23 and move towards the teeth 24. When the toothed blocks 35 have completely moved into the rectangular frame 22, the teeth on the corner blocks 353 are in complete contact with the teeth 24 in the rectangular frame 22, thus locking the locking assembly 3 and ensuring that the valve body is stably installed at the required height.

[0036] It should be noted that the function of the first spring 352 is: when adjusting the installation height of the valve body, it is necessary to release the locking component 3. As the toothed block 35 moves away from the rectangular frame 22, the first spring 352 will contract, thereby driving the corner block 353 to move away from the toothed part 24.

[0037] Furthermore, the clamping assembly 5 includes a threaded post 51 inserted into the through hole 41, a universal joint 52 fixedly disposed on the threaded post 51, a rotating frame 53 symmetrically disposed on the left and right sides of the universal joint 52, and a threaded sleeve 54 rotatably connected to the threaded post 51.

[0038] Furthermore, the clamping assembly 5 also includes a top block 55 rotatably mounted on the left rotating frame 53, a first clamping block 56 rotatably mounted on the right rotating frame 53, two sets of second springs 57 respectively fixedly mounted on both sides of the first clamping block 56, a second clamping block 58 fixedly mounted on the other end of the second spring 57, and a connecting post 59 fixedly mounted on the second clamping block 58.

[0039] Furthermore, the connecting post 59 passes through the second spring 57 and the first clamping block 56, and the end of the connecting post 59 away from the second clamping block 58 is fixedly connected to the top block 55; a guide rail is provided on the worktable, and the top block 55, the first clamping block 56 and the second clamping block 58 are all slidably connected to the worktable 4.

[0040] In use, the valve body is first placed between the first clamping block 56 and the second clamping block 58. Then, the threaded post 51 is pressed down, and the threaded post 51 moves downward within the through hole 41. The rotating brackets 53 on both sides of the threaded post 51 also rotate. Under the action of the two sets of rotating brackets 53, on the one hand, the top block 55 moves away from the first clamping block 56. Since the two ends of the connecting post 59 are connected to the top block 55 and the second clamping block 58 respectively, the second clamping block 58 moves towards the first clamping block 56 under the drive of the top block 55. On the other hand, the first clamping block 56 also moves closer to the second clamping block 58. The first clamping block 56 and the second clamping block 58 will then form a relative movement, making the valve body securely fixed between them. At the same time, the threaded post 51 will extend out of the through hole 41. Then, the threaded sleeve 54 is screwed into the threaded post 51 and comes into contact with the bottom of the worktable 4, thus completing the installation of the valve body.

[0041] It should be noted that the function of the second spring 57 is to enable the first clamping block 56 and the second clamping block 58 to automatically reset, facilitating the next operation. On the other hand, with the second spring 57, the first clamping block 56, and the second clamping block 58 working together, valve bodies of different sizes can be stably clamped and installed.

[0042] Furthermore, the telescopic assembly 6 includes a telescopic rod 61 movably connected to the bottom of the workbench 4, and a rotating seat 62 located at the other end of the telescopic rod 61; the rotating seat 62 is movably connected to the base 1.

[0043] It should also be noted that the telescopic shaft 61 is equipped with a locking mechanism. When the telescopic shaft 61 needs to be adjusted to a suitable length, simply press the locking mechanism to lock the length of the telescopic shaft 61. (This locking mechanism is existing technology and will not be described in detail here).

[0044] When in use, first unlock the locking mechanism of the telescopic shaft 61 to facilitate the downward movement of the worktable 4; when the installation height of the valve body is adjusted, the length of the telescopic shaft 61 will also be adjusted, and then the telescopic shaft 61 will be locked by the locking mechanism.

[0045] It should also be noted that, regardless of the adjusted installation height, the support frame 2, the telescopic component 6, and the worktable 4 will form a triangular structure, providing a stable frame for the valve body during turning. Another advantage is that it allows the slider 31, the worktable 4, and the clamping component 5 to remain stable while the wrench 36 is rotated, preventing them from rotating due to the rotation of the wrench 36.

[0046] Working Principle: First, the valve body is placed on the clamping assembly 5. Through the cooperation of the clamping assembly 5 and the worktable 4, the valve body is securely mounted on the clamping assembly 5. When the installation height of this device needs to be adjusted, first release the locking assembly 3 from its limit on the support frame 2, allowing the locking assembly 3 to move up and down on the support frame 2. The worktable 4 is connected to the locking assembly 3 and the clamping assembly 5, so the clamping assembly 5 will also move under the influence of the locking assembly 3, thus adjusting the installation height of the valve body on this device. After adjusting the installation height, the locking assembly 3 is then rotated to lock it. Simultaneously, the telescopic assembly 6 must also be released to shorten its overall length. After adjusting the installation height, the telescopic assembly 6 is then locked.

[0047] In summary, this multi-position valve body turning device for automotive air conditioning compressor control valves, through the cooperation of multiple sets of rectangular frames, ramps, teeth, and locking components on the support frame, can achieve stable adjustment and locking of the valve body at different installation heights, thereby meeting the requirements for multi-position turning of the valve body; by using universal joints, rotating frames, and first and second clamping blocks in the clamping components, valve bodies of different sizes can be firmly clamped and the stability of the valve body can be maintained during the machining process.
