Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] Please refer to Figures 1 to 8 Example 1:

[0042] This utility model proposes a multi-functional auxiliary installation tool for assembling valve pump housings, including: a base plate 1;

[0044] In this embodiment of the disclosure,

[0045] A first lead screw 121 and a second lead screw 122 are mounted on the base plate 1 via bearings. The lower ends of the first sliding plate 13 and the second sliding plate 14 are each provided with threaded holes, which are threaded into the first lead screw 121 and the second lead screw 122, respectively. Furthermore, a first motor 1211 and a second motor 1221 are mounted on the base plate 1 via bolts. The output shafts of the first motor 1211 and the second motor 1221 are respectively... The coupling connects to lead screw 121 and lead screw 122. Its function is to engage the lead screw 121 and lead screw 122 on the base plate 1 with the threaded holes at the lower ends of sliding plates 13 and 14, and drive them with motors 1211 and 1221. This allows for precise control of the position of sliding plates 13 and 14 on the rail rod 12, adapting to the assembly requirements of valve and pump housings of different specifications, and improving the versatility and applicability of the device.

[0046] In this embodiment of the disclosure,

The piston rod of the hydraulic rod 221 is fixedly connected to the upper end of the lifting seat 21. The lifting seat 21 has a through hole and two sets of vertical rods 211 are fixed on it. Movable plates 212 are movable on the two sets of vertical rods 211. Springs are fitted on both sets of vertical rods 211. The function of these springs is to allow the extension and retraction of the hydraulic rod 221 to precisely adjust the height of the valve component placed on the lifting seat 21 according to the actual needs of the valve pump housing assembly. The vertical rods 211, the movable plates 212, and the springs fitted on the vertical rods 211 together form a buffer and fine-tuning structure.

[0048] In this embodiment of the disclosure,

[0049] A connecting seat 23 is fixed to the lower end of the movable plate 212. Three sets of hinge arms 231 are installed at the lower end of the connecting seat 23 via pins. Clamping heads 2311 are installed at the lower end of each of the three sets of hinge arms 231 via pins. A second hydraulic rod 232 is fixed to the lower end of the connecting seat 23.

A movable first connecting rod 2332 is connected to the connecting column 2331. A second connecting rod 2333 is threaded onto the first connecting rod 2332. The second connecting rod 2333 is movably connected to the hinge arm 231. Its function is to adjust the position of the connecting plate 233 by extending and retracting the second hydraulic rod 232. The connecting plate 233 drives the three sets of hinge arms 231 to move through the first connecting rod 2332 and the second connecting rod 2333, thereby opening and clamping the clamping heads 2311.

[0050] In this embodiment of the disclosure,

[0051] A No. 3 motor 31 is bolted onto the track plate 3. A pulley is fixed on the output shaft of the No. 3 motor 31. A pulley is mounted on the track plate 3. A transmission belt 32 is connected between the two sets of pulleys. The transmission belt 32 is fixedly connected to the lower end of the moving plate 33. Its function is to run the No. 3 motor 31 to make the transmission belt 32 rotate, and the moving plate 33 can be moved back and forth through the transmission belt 32.

[0052] Example 2, based on Example 1,

[0053] A cylinder seat 3411 is bolted onto the partition plate 341. A third hydraulic rod 3412 is mounted on the cylinder seat 3411. A slider 3413 slides on the partition plate 341. A toothed plate 3414 is fixed on the slider 3413. The slider 3413 is fixedly connected to the piston rod of the third hydraulic rod 3412. A gear is fixed on the rotating rod 342, and the gear meshes with the toothed plate 3414. Its function is to extend and retract the third hydraulic rod 3412 to move the toothed plate 3414, and drive the rotating rod 342 to rotate through the toothed plate 3414, thereby realizing the rotation of the turntable 343.

[0054] Example 3, based on Examples 1 and 2,

[0055] Two sets of No. 4 hydraulic rods 351 are fixed on the positioning seat 35. Each set of No. 4 hydraulic rods 351 is bolted to a hinge seat 3511. A connecting plate 3512 is mounted on the hinge seat 3511 via a pin. A lower pressure arm 3513 is mounted on the upper end of the connecting plate 3512 via a pin. The lower pressure arm 3513 is connected to the piston rod of the No. 4 hydraulic rod 351 via a pin. The positioning seat 35 is equipped with a pump housing body 36. The two sets of lower pressure arms 3513 press down on the pump housing body 36. Their function is to extend the piston rod of the No. 4 hydraulic rod 351. The lower pressure arm 3513 will rotate around the pin connected to the connecting plate 3512 as a fulcrum and finally press down on the pump housing body 36. This prevents the pump housing body 36 from being displaced or shaking due to external factors during the assembly process.

[0056] The working principle of this embodiment is as follows: When the No. 1 motor 1211 and No. 2 motor 1221 on the base plate 1 are started, the output shaft of the No. 1 motor 1211 drives the No. 1 lead screw 121 to rotate via a coupling. Because the threaded hole at the lower end of the No. 1 sliding plate 13 is threadedly engaged with the No. 1 lead screw 121, the No. 1 sliding plate 13 slides on the rail rod 12. Similarly, the No. 2 motor 1221 drives the No. 2 lead screw 122 to rotate, driving the No. 2 sliding plate 14 to slide on the rail rod 12. This allows for flexible adjustment of the various components of the installation device. To accommodate the assembly requirements of valve and pump housings of different specifications, the piston rod of the second hydraulic rod 232 extends and pushes the connecting plate 233 downward. The connecting column 2331 on the connecting plate 233 drives the first connecting rod 2332 and the second connecting rod 2333, causing the hinge arm 231 to rotate around the pin, which in turn drives the clamping head 2311 to close, stabilizing the valve. The extension and retraction of the first hydraulic rod 221 adjusts the height of the clamping head 2311. The two sets of fourth hydraulic rods 351 on the positioning seat 35 are activated, and the piston rod... Extending the push arm 3513, the push arm 3513 rotates around the pin shaft through the cooperation of the connecting plate 3512 and the hinge seat 3511, applying pressure to the pump casing body 36 and stabilizing it on the positioning seat 35. This ensures a tight fit between the valve and the pump casing during assembly, improving assembly quality. The third motor 31 is then activated, and the pulley on its output shaft drives the transmission belt 32. Because the transmission belt 32 is fixed to the lower end of the moving plate 33, the moving plate 33 slides on the track plate 3, driving the mounting cylinder 34 and the positioning seat. 35 moves horizontally, transporting the pump housing body 36 to the assembly position. If the pump housing angle needs to be adjusted, the third hydraulic rod 3412 in the cylinder seat 3411 on the partition 341 is activated. The piston rod pushes the slider 3413, which drives the toothed plate 3414 to slide. The toothed plate 3414 meshes with the gear on the rotating rod 342, causing the rotating rod 342 to rotate. This drives the turntable 343 and the pump housing body 36 on the positioning seat 35 to rotate to the required angle, ensuring that the valve and the pump housing fit tightly during assembly and improving the assembly quality.
