Description

Technical Field

[0001] This utility model belongs to the field of oil pump processing technology, specifically an oil pump processing tooling fixture. Background Technology

[0002] An oil pump is a mechanical device used to transport and pressurize liquid oils, widely used in industries such as manufacturing, automotive, shipbuilding, and construction machinery. It uses a motor or other drive unit to rotate internal components such as rotors, gears, or blades, drawing oil from a tank and delivering it to the target system to achieve functions such as lubrication, cooling, and hydraulic transmission. Due to the complex structure of oil pumps, a tooling fixture is required to ensure the positioning accuracy and clamping stability of pump components during processing.

[0003] Oil pump machining fixtures are auxiliary devices specifically used in the machining process of oil pump parts. In traditional technology, oil pump machining fixtures mostly use bolt plates or single-sided clamping mechanisms to fix the workpiece. These fixtures not only require a lot of manual intervention during clamping, but are also prone to workpiece displacement or deformation due to asymmetrical clamping, which affects the machining of oil pump parts. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an oil pump processing tooling fixture, which effectively solves the problem that existing oil pump processing tooling fixtures mostly use bolt pressure plates or single-sided clamping mechanisms to fix the workpiece, which is prone to workpiece displacement or deformation due to asymmetrical clamping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil pump processing fixture, comprising a worktable, a hollow box fixedly connected inside the worktable, an electric push rod fixedly connected inside the hollow box, a shaped frame fixedly connected to the output end of the electric push rod, a toothed plate fixedly connected to the outer wall of the shaped frame, a gear meshing with the toothed end of the toothed plate, a support rod fixedly connected inside the gear, the bottom end of the support rod rotatably connected to the inside of the hollow box, a U-shaped frame fixedly connected to the upper surface of the shaped frame, a sliding rod slidably connected inside the U-shaped frame, both ends of the sliding rod fixedly connected to the inner wall of the hollow box, the outer wall of the U-shaped frame slidably connected to the inside of the hollow box, a fixing block fixedly connected to the outer wall of the U-shaped frame, a clamping block provided on the outer wall of the fixing block, and a protective component provided on the outer wall of the clamping block.

[0006] Preferably, the protective component includes a protective pad, the outer wall of which is fixedly connected to the outer wall of the clamping block, and the outer wall of the protective pad is disposed on the outer wall of the fixed block.

[0007] Preferably, a fixing rod is slidably connected inside the clamping block, and the outer wall of the fixing rod is fixedly connected to the outer wall of the fixing block.

[0008] Preferably, the clamping block is internally threaded with a lead screw, and the outer wall of the lead screw is fixedly connected with a bearing.

[0009] Preferably, the outer wall of the bearing is fixedly connected to the inside of the fixing block, and the outer wall of the lead screw is fixedly connected to a disc.

[0010] Preferably, a connecting rod is slidably connected inside the disk, and the outer wall of the connecting rod is slidably connected inside the fixed block.

[0011] Preferably, a circular block is fixedly connected to the outer wall of the connecting rod, and the outer wall of the circular block is disposed on the outer wall of the fixed block.

[0012] Preferably, a spring is fixedly connected to the outer wall of the circular block, and the outer wall of the spring is fixedly connected to the outer wall of the disc.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, by activating the electric push rod, the irregular frame is pushed or pulled to move, which in turn moves the U-shaped frame and the toothed plate. The toothed plate drives the gear and the support rod to rotate in the forward or reverse direction, causing the toothed plates and the U-shaped frame on both sides to move towards the center of the support rod or towards the outside of the hollow box. The support rod is located at the center of the hollow box, thereby clamping and fixing or releasing the oil pump or oil pump component above the hollow box, ensuring the symmetry and stability of the clamping, making the workpiece positioning more accurate, and improving the consistency of workpiece fixing, thereby reducing manual adjustment time and improving clamping efficiency.

[0014] By pulling the connecting rod, the circular block moves outward, compressing the spring. After the connecting rod slides out of the fixed block, the replacement clamping block slides towards the fixed rod, placing the fixed rod inside the clamping block. Simultaneously, the disc and lead screw rotate. Through the engagement of the lead screw and the internal threads of the clamping block, the clamping block moves towards the fixed block, bringing the outer wall of the clamping block and protective pad into contact with the outer wall of the fixed block. Finally, the connecting rod is released, and under the spring force, it slides into the fixed block, limiting the rotation of the lead screw and disc. This allows for the installation and removal of the clamping block, facilitating the replacement of clamping blocks of appropriate specifications for different models or sizes of oil pumps or their components, improving the versatility of the fixture, and also facilitating timely cleaning and maintenance of the clamping block.

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

[0023] Depend on Figure 1 and Figure 2 The present invention includes a workbench 1, a hollow box 2 fixedly connected inside the workbench 1, an electric push rod 3 fixedly connected inside the hollow box 2, a shaped frame 4 fixedly connected to the output end of the electric push rod 3, a toothed plate 5 fixedly connected to the outer wall of the shaped frame 4, a gear 6 meshing with the toothed end of the toothed plate 5, a support rod 7 fixedly connected inside the gear 6, the bottom end of the support rod 7 rotatably connected to the inside of the hollow box 2, a U-shaped frame 8 fixedly connected to the upper surface of the shaped frame 4, a sliding rod 9 slidably connected inside the U-shaped frame 8, both ends of the sliding rod 9 fixedly connected to the inner wall of the hollow box 2, the outer wall of the U-shaped frame 8 slidably connected to the inside of the hollow box 2, a fixing block 10 fixedly connected to the outer wall of the U-shaped frame 8, a clamping block 11 provided on the outer wall of the fixing block 10, and a protective component provided on the outer wall of the clamping block 11.

[0024] In use, the oil pump or oil pump component is placed above the hollow box 2. The electric push rod 3 is activated to pull the irregular frame 4, which in turn moves the toothed plate 5 and the U-shaped frame 8. The movement of the U-shaped frame 8 is supported and its offset is limited by the fixed sliding rod 9. The movement of the toothed plate 5 drives the support rod 7 and the gear 6 to rotate. The rotation of the support rod 7 and the gear 6 is supported by the inside of the hollow box 2. The toothed plates 5 on both sides of the gear 6 move the U-shaped frame 8 and the toothed plates 5 on both sides towards the center of the support rod 7 as the gear 6 rotates. This causes the fixed blocks 10 and the clamping blocks 11 on both sides to move towards the center of the support rod 7, clamping and fixing the oil pump or oil pump component above the hollow box 2. The worktable 1 has grooves on all four sides for bolting to different processing platforms, allowing for different processing methods for the oil pump or oil pump component. At the same time, the clamping and fixing improves the stability of the oil pump or oil pump component during processing. The movement of the U-shaped frame 8 is limited by the inside of the hollow box 2.

[0025] Depend on Figure 2 The protective assembly includes a protective pad 12, the outer wall of which is fixedly connected to the outer wall of the clamping block 11, and the outer wall of the protective pad 12 is disposed on the outer wall of the fixing block 10.

[0026] The protective pads 12 on the upper and lower sides are made elastic, and the side near the outer wall of the fixing block 10 is made rough, which helps to improve the stability between the clamping block 11 and the fixing block 10 and avoids excessive hard contact between the clamping block 11 and the fixing block 10, thereby protecting the clamping block 11.

[0027] Depend on Figure 3 and Figure 4 As shown, a fixing rod 13 is slidably connected inside the clamping block 11, and the outer wall of the fixing rod 13 is fixedly connected to the outer wall of the fixing block 10; a lead screw 14 is threaded inside the clamping block 11, and a bearing 15 is fixedly connected to the outer wall of the lead screw 14; the outer wall of the bearing 15 is fixedly connected to the inside of the fixing block 10, and a disc 16 is fixedly connected to the outer wall of the lead screw 14; a connecting rod 17 is slidably connected inside the disc 16, and the outer wall of the connecting rod 17 is slidably connected to the inside of the fixing block 10; a circular block 18 is fixedly connected to the outer wall of the connecting rod 17, and the outer wall of the circular block 18 is set on the outer wall of the fixing block 10; a spring 19 is fixedly connected to the outer wall of the circular block 18, and the outer wall of the spring 19 is fixedly connected to the outer wall of the disc 16;

[0028] By pulling the connecting rod 17 to the right, the circular block 18 moves to the right, compressing the spring 19 and causing the connecting rod 17 to slide out of the fixed block 10, no longer limiting the circular block 16. By holding the connecting rod 17, the circular block 16 rotates forward, causing the circular block 16 and the lead screw 14 to rotate under the action of the bearing 15. As the lead screw 14 rotates forward, the clamping block 11 moves to the left under the limitation of the fixed rod 13, thus allowing the clamping block 11 to be disassembled for maintenance or replacement. Through the bearing 15, the lead screw 19... 4. To achieve the supporting effect, the fixed rod 13 and the groove inside the clamping block 11 are used to position and limit the installation of the clamping block 11. At the same time, the clamping block 11 is also limited to facilitate its disassembly. The distance between the round block 18 and the disc 16 limits the range of movement of the connecting rod 17. Without external force driving the connecting rod 17, the elastic force of the spring 19 is used to push the connecting rod 17 into the interior of the fixed block 10, thereby limiting the disc 16 and the lead screw 14 and preventing the lead screw 14 from rotating unexpectedly.
