A fixture assembly is symmetrically arranged on the top of the support platform, and a support assembly is symmetrically arranged on the top of the support platform to support the fixture assembly. The outer wall of a mounting plate is slidably sleeved with a mounting housing. An adjusting screw for height adjustment is located inside the mounting housing. The bottom of the adjusting screw's outer wall is rotatably sleeved with the mounting housing. A threaded groove is formed on the bottom of the mounting plate, and the top of the adjusting screw's outer wall is threadedly sleeved with the inner cavity of the threaded groove. This invention utilizes the combined use of the support platform, fixture assembly, and support assembly. By rotating the adjusting screw, the height of the mounting plate and fixture assembly can be changed, allowing the fixture to clamp and fix the submersible pump housing in place. Furthermore, under the action of a positioning rod and elastic rope, the connecting cap can be engaged with the bottom of the mounting housing, ensuring the stability of the adjusting screw and the mounting housing.

[0004] However, the above-mentioned clamps still have some shortcomings in use. Submersible pumps come in a variety of models, and different submersible pumps have different housing sizes. The above-mentioned clamps can only be used to clamp and fix housings of certain specific sizes, and cannot be used for housings of different sizes, resulting in poor applicability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning and fastening jig for submersible pump housing processing. This solves the problem that submersible pumps come in various models with different housing sizes, and the aforementioned jigs can only be used for clamping and fixing housings of specific sizes, thus having poor applicability.

[0006] This utility model provides the following technical solution: a positioning and fastening submersible pump housing processing fixture, including a worktable, the upper surface of the worktable having two grooves, one of which has a bidirectional lead screw rotatably connected between its inner two side walls, and two lead screw sleeves threaded onto the surface of the bidirectional lead screw, the other of which has a slide rod fixedly connected between its inner two side walls, and two slide sleeves slidably connected onto the surface of the slide rod, the top ends of the two slide sleeves and the two lead screw sleeves being fixedly connected to a mounting box;

[0007] Each of the mounting boxes is fixedly connected to one end of a first clamping plate, and each of the first clamping plates is movably hinged to its upper and lower ends with a second clamping plate. Each of the mounting boxes is provided with an adjustment component.

[0008] Preferred technical solution 1: The adjustment component includes a screw rod rotatably installed inside the mounting box, the surface of the screw rod being threaded with a threaded sleeve, and a connecting rod being movably connected between the upper and lower surfaces of the threaded sleeve and the corresponding second clamping plate.

[0009] Preferred technical solution 2: Each of the mounting boxes has a sliding groove on its inner wall, and a slider is slidably installed inside each sliding groove. Each slider is fixedly connected to the corresponding screw sleeve.

[0010] Preferred technical solution 3: A first motor is fixedly installed on the surface of each mounting box, the output end of each first motor extends into the interior of the connected mounting box and is fixedly connected to a first bevel gear, and a second bevel gear is fixedly sleeved on the surface of each screw, with the first bevel gear and the second bevel gear meshing with each other.

[0011] Preferred technical solution four: A second motor is fixedly connected to the side of the worktable, the output end of the second motor extends into the interior of one of the grooves and is fixedly connected to the bidirectional lead screw, and crossbars are fixedly connected between the two lead screw sleeves and the two sliding sleeves respectively.

[0012] Preferred technical solution five: Support columns are fixedly connected to the four corners of the lower surface of the workbench, and an anti-slip pad is provided at the bottom of each support column. The anti-slip pad is made of rubber, and a rubber pad is fixedly adhered to the surface of each first clamping plate and each second clamping plate.

[0013] Compared with the prior art, this utility model provides a positioning and fastening submersible pump housing processing fixture, which has the following beneficial effects: In use, the submersible pump housing to be processed is placed between four first clamping plates. Then, the rotation of the second motor drives the bidirectional lead screw to rotate, thereby driving the two lead screw sleeves and two sliding sleeves to move downward, initially clamping and fixing the housing. Then, by controlling the rotation of the first motor, the screw is driven to rotate, thereby driving the screw sleeve to move. The second clamping plate can then be driven to rotate through the transmission of the connecting rod, so that the second clamping plate further clamps and fixes the housing, making it more stable.

[0014] This clamp can quickly clamp and fix submersible pump housings of different sizes during use, making it highly versatile. Attached Figure Description

Detailed Implementation

[0020] Please see Figure 1-4 ,

[0021] Example 1: A positioning and fastening submersible pump housing machining fixture includes a worktable 1. The upper surface of the worktable 1 has two grooves 2. A bidirectional lead screw 3 is rotatably connected between the two inner side walls of one groove 2. Two lead screw sleeves 4 are threaded onto the surface of the bidirectional lead screw 3. A slide rod 5 is fixedly connected between the two inner side walls of the other groove 2. Two slide sleeves 6 are slidably connected to the surface of the slide rod 5. The top ends of the two slide sleeves 6 and the two lead screw sleeves 4 are fixedly connected to a mounting box 7.

[0022] Each mounting box 7 is fixedly connected to one end of a first clamping plate 8, and each first clamping plate 8 is movably hinged to the upper and lower ends of a second clamping plate 9. Each mounting box 7 is equipped with an adjustment component.

[0023] Example 2: The difference between this example and Example 1 is that the adjusting component includes a screw 10 rotatably installed inside the mounting box 7. A screw sleeve 11 is threaded onto the surface of the screw 10. A connecting rod 12 is movably connected between the upper and lower surfaces of the screw sleeve 11 and the corresponding second clamping plate 9. The screw 10 rotates to move the screw sleeve 11, and the connecting rod 12 drives the second clamping plate 9 to rotate, thereby further clamping and fixing the housing.

[0024] Example 3: The difference between this example and Example 1 is that each mounting box 7 has a groove 13 on its inner wall, and a slider 14 is slidably installed inside each groove 13. Each slider 14 is fixedly connected to the corresponding screw sleeve 11, which facilitates the restriction of the movement of the screw sleeve 11.

[0025] Example 4: The difference between this example and Example 1 is that each mounting box 7 has a first motor 15 fixedly mounted on its surface, the output end of each first motor 15 extends into the interior of the connected mounting box 7 and is fixedly connected to a first bevel gear 16, and a second bevel gear 17 is fixedly sleeved on the surface of each screw 10, with the first bevel gear 16 and the second bevel gear 17 meshing with each other.

[0026] Example 5: The difference between this example and Example 1 is that a second motor 18 is fixedly connected to the side of the workbench 1. The output end of the second motor 18 extends into the interior of one of the grooves 2 and is fixedly connected to the bidirectional lead screw 3. A crossbar 19 is fixedly connected between the two lead screw sleeves 4 and the two sliding sleeves 6 respectively. The rotation of the second motor 18 drives the first clamping plate 8 to move, and initially clamps and fixes the shell.

[0027] Example 6: The difference between this example and Example 1 is that the four corners of the lower surface of the workbench 1 are fixedly connected with support columns 20, and each support column 20 is provided with an anti-slip pad at its bottom. The anti-slip pad is made of rubber. Rubber pads are fixedly adhered to the surface of each first clamping plate 8 and each second clamping plate 9, making the workbench more stable. At the same time, the rubber pads can protect the shell and prevent damage to the shell due to excessive clamping force.

[0028] In summary, when using this positioning and fastening submersible pump housing processing fixture, the submersible pump housing to be processed is placed between the four first clamping plates 8. Then, the rotation of the second motor 18 drives the bidirectional lead screw 3 to rotate, thereby causing the two lead screw sleeves 4 and the two sliding sleeves 6 to move downward, initially clamping and fixing the housing. Then, by controlling the rotation of the first motor 15, the screw 10 is driven to rotate, thereby causing the screw sleeve 11 to move. This allows the second clamping plate 9 to rotate through the transmission of the connecting rod 12, so that the second clamping plate 9 further clamps and fixes the housing, making it more stable.

[0029] This clamp can quickly clamp and fix submersible pump housings of different sizes during use, making it highly versatile.
