Description

Technical Field

[0001] This utility model relates to a clamping fixture, specifically a pump body turning clamping fixture, and belongs to the field of clamping fixture technology. Background Technology

[0002] The pump body is the core pressure-bearing and structural component of a hydraulic pump. Internally, it requires precision-machined oil passages to accommodate valve groups and oil flow. Externally, it needs to form assembly structures such as flanges and positioning holes. Its dimensional accuracy, geometric tolerances, and surface roughness directly affect the sealing performance, pressure transmission efficiency, and operational stability of the hydraulic pump. Since the pump body requires precision correction of key parts such as the end face, outer diameter, and inner hole after forming, turning becomes the core manufacturing process to ensure that the dimensional tolerances of each machined surface meet assembly requirements. During turning, the pump body rotates at high speed and must withstand cutting forces, requiring clamping fixtures for fixation. Currently, a two-jaw chuck is commonly used as the basic clamping structure. By replacing clamping blocks of different specifications and shapes, it can be adapted to the irregular structure of the pump body, meeting diverse clamping needs.

[0003] However, the slider and guide rail of the two-jaw chuck are in direct metal-to-metal contact. During the turning process, the slider will slide frequently with the clamping action, which can easily lead to wear on the contact surface. Currently, it only relies on manual periodic lubrication, which often results in untimely lubrication or uneven oil volume. This will not only accelerate the wear of the slider and guide rail, but also shorten the service life of the tooling. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 As shown, a pump body turning clamping fixture includes a mounting base 1, a chuck 2 rotatably connected to the mounting base 1, two sliders 7 slidably connected to the chuck 2, clamping blocks 8 mounted on the sliders 7, a lubrication structure 3 on the chuck 2, the lubrication structure 3 including mounting plates 301, four mounting plates 301 mounted on the chuck 2, sponges 302 fixedly connected to the mounting plates 301, the sponges 302 abutting against the sliders 7, four oil storage chambers 304 on the chuck 2, four pressure boosting boxes 305 fixedly connected to the chuck 2, pistons 306 slidably connected inside the pressure boosting boxes 305, second check valves 307 mounted on the pistons 306, and four first check valves 303 mounted on the chuck 2.

[0026] As a technical optimization of this utility model, four oil filling pipes 308 are installed on the chuck 2, and the four oil filling pipes 308 are respectively connected to four oil storage chambers 304. The piston 306 is driven by the first driving structure 4. The first driving structure 4 includes a fixed rod 401, and the fixed rod 401 is fixedly connected to the piston 306. A sliding rod 402 is fixedly connected between every two fixed rods 401. The sliding rod 402 is slidably connected to the chuck 2. When the first driving member 506 retracts, when the inclined surface of the driving rod 408 slides and engages with the inclined surface of the connecting block 406 on the connecting plate 405, it will push the sliding rod 402 to slide along the guide rod 403 and compress the first spring 404. The sliding rod 402 then drives the piston 306 to slide in the pressure box 305 through the fixed rod 401. At this time, the second one-way valve 307 is closed and the first one-way valve 303 is open. The lubricating oil in the oil storage chamber 304 is forced into the sponge 302 through the first one-way valve 303. The sponge 302 abuts against the slider 7 and can evenly spread the lubricating oil on the sliding contact surface as the slider 7 slides, realizing the synchronous operation of clamping and lubrication, which improves the service life of the slider 7. At the same time, lubricating oil can be added to the oil storage chamber 304 through the oil filling pipe 308. A connecting plate 405 is fixedly connected to the slide rod 402. The connecting plate 405 is slidably connected to the chuck 2. Two drive rods 408 are slidably connected to the chuck 2. A connecting block 406 is fixedly connected to the connecting plate 405. The inclined surface of the drive rod 408 slides and engages with the inclined surface of the connecting block 406. A guide rod 403 is fixedly connected inside the chuck 2. The slide rod 402 is slidably connected to the guide rod 403. A first spring 404 is fixedly connected between the slide rod 402 and the chuck 2.

[0027] As a technical optimization of this utility model, the slider 7 is driven by the second driving structure 5. The second driving structure 5 includes a driving frame 501, and the driving frame 501 is fixedly connected to the slider 7. The driving frame 501 is provided with an inclined driving groove 502. A connecting rod 504 is slidably connected to the chuck 2. Two driving rods 408 are slidably connected to the connecting rod 504. A driving block 503 is fixedly connected to the connecting rod 504. Then, the hydraulic pump body is placed in the center of the chuck 2, and the first driving component 506 (preferably a hydraulic rod) is started. Its driving end pushes the connecting column 505 to move the connecting rod 504. The driving block 503 on the connecting rod 504 slides in the inclined driving groove 502 of the driving frame 501. This causes the two sliders 7 to slide towards each other along the chuck 2. The clamping blocks 8 on the sliders 7 gradually approach and clamp the pump body. The drive block 503 slides in cooperation with the inclined drive groove 502. The connecting rod 504 is fixedly connected to the connecting column 505. The connecting column 505 is driven by the first drive member 506. The first drive member 506 is mounted on the mounting base 1. The connecting column 505 is rotatably connected to the drive end of the first drive member 506. The mounting base 1 is rotatably connected to the rotating shaft 508. The rotating shaft 508 is fixedly connected to the gear 509. The chuck 2 is fixedly connected to the gear ring 507. The gear 509 meshes with the gear ring 507. The mounting base 1 is equipped with the second drive member 510. The rotating shaft 508 is driven by the second drive member 510.

[0028] As a technical optimization of this utility model, the clamping block 8 is mounted on the slider 7 via the mounting structure 6. The mounting structure 6 includes a stop 601, which is fixedly connected to the slider 7. The clamping block 8 is slidably connected to the stop 601, and an mounting block 602 is slidably connected to the stop 601. The mounting block 602 engages with the clamping block 8. By replacing the appropriate clamping block 8, pulling the pull rod 604 causes the mounting block 602 to compress the second spring 605 and disengage from the engagement between the stop 601 and the clamping block 8, thus allowing the appropriate clamping block 8 to engage. The clamping block 8 slides into the stop block 601, the pull rod 604 is released, and the second spring 605 resets and pushes the mounting block 602 to re-engage with the clamping block 8, completing the quick replacement. The clamping block 8 can be disassembled and assembled without tools, improving the adaptability to pump bodies of different specifications. A fixing plate 603 is fixedly connected to the stop block 601, and a pull rod 604 is fixedly connected to the mounting block 602. The pull rod 604 is slidably connected to the fixing plate 603, and a second spring 605 is fixedly connected between the mounting block 602 and the fixing plate 603.

[0029] In use, this utility model first involves replacing the appropriate clamping block 8, pulling the lever 604, which causes the mounting block 602 to compress the second spring 605 and disengage from the stop block 601 and clamping block 8. The appropriate clamping block 8 is then slid into the stop block 601. Releasing the lever 604 causes the second spring 605 to reset, pushing the mounting block 602 and clamping block 8 back into engagement, completing a quick replacement. The clamping block 8 can be installed and removed without tools, improving the compatibility efficiency with pump bodies of different specifications. Next, the hydraulic pump body is placed in the clamping block... At the center of disc 2, the first driving component 506 (preferably a hydraulic rod) is activated. Its driving end pushes the connecting column 505, causing the connecting rod 504 to move. The driving block 503 on the connecting rod 504 slides in the inclined driving groove 502 of the driving frame 501, thereby causing the two sliders 7 to slide towards each other along the chuck 2. The clamping blocks 8 on the sliders 7 gradually approach and clamp the pump body. When the connecting rod 504 moves, it also causes the two driving rods 408 to move synchronously. When the first driving component 506 retracts, the inclined surface of the driving rod 408 and the connecting plate 40 When the inclined surface of the connecting block 406 slides, it pushes the slide rod 402 to slide along the guide rod 403 and compresses the first spring 404. The slide rod 402 then drives the piston 306 to slide in the pressure box 305 through the fixed rod 401. At this time, the second one-way valve 307 is closed and the first one-way valve 303 is open. The lubricating oil in the oil storage chamber 304 is forced into the sponge 302 through the first one-way valve 303. The sponge 302 abuts against the slider 7 and can evenly spread the lubricating oil on the sliding contact surface as the slider 7 slides, realizing clamping. The simultaneous operation of holding action and lubrication improves the service life of slider 7. At the same time, lubricating oil can be replenished to oil storage chamber 304 through oil filling pipe 308. After processing is completed, the driving end of the first driving member 506 retracts, and slider 7 releases the pump body under the action of reverse driving force. During processing, the second driving member 510 (preferably a motor) is started, and its driving end drives the rotating shaft 508 and gear 509 to rotate. Gear 509 meshes with the gear ring 507 on chuck 2, thereby driving chuck 2 to rotate around mounting base 1, realizing the rotation of pump body.
