Early swash plate pumps had a relatively simple structure and relatively low performance and reliability. With the development of materials science, manufacturing processes, and control technology, the performance of swash plate pumps has been greatly improved. Today, swash plate pumps have become an indispensable component of hydraulic systems.

[0003] The swash plate grinding tooling used in swash plate pump machining is a tool specifically used for swash plate grinding. It can ensure the accuracy and stability of the swash plate during the grinding process. When machining swash plates of different models of swash plate pumps, due to changes in the inclination angle, the existing tooling may not meet the requirements, requiring frequent tooling replacement or adjustment, which increases the complexity and time cost of the operation and affects the machining accuracy and stability.

Debris will be generated during the polishing process, and a protective cover is provided to prevent the debris generated by polishing from being scattered in the working environment and polluting the air and the ground.

A circular plate is provided inside the base. In the initial state, the elastic rope is in a taut state. Under the pulling force of multiple elastic ropes, the circular plate is in a horizontal state. When the top of the fixed swash plate is not in a horizontal state, the swash plate drives the round rod inside the middle shaft hole to deviate, so that the round rod drives the circular plate to deviate, and the circular plate rotates on the ball. At this time, extrusion is generated between the limiting plate on the top of the circular plate and the fixed frame, and the limiting plate pushes The movable fixed frame moves, thereby driving the fan-shaped plate and the inclined plate to rotate, so that the top of the inclined plate is in a horizontal state. At the same time, the circular plate is reset under the action of the elastic rope. A groove is provided in the middle of the bottom of the circular plate.

[0013] The present invention provides a swash plate grinding tool for machining a swash plate pump. It has the following beneficial effects:

[0014] The swash plate grinding fixture used in this swash plate pump machining utilizes three fixings and a swash plate to securely clamp the swash plate according to its shape, improving its stability. Simultaneously, a slider drives the fixing block to contact the outer side of the swash plate. The contact plate is forced to move on the fixing block. The spring force of the spring plate causes the contact plate to contact the swash plate, thus elastically clamping the plate to prevent damage to the swash plate caused by excessive clamping force.

[0015] Second, the swash plate grinding tooling for the swash plate pump uses a swash plate and a rotating rod. During the process of fixing the swash plate, the swash plate can be rotated around the rotating rod according to the inclination angle of the swash plate's bevel edge, so that the swash plate and the swash plate fit together. This allows the swash plates with different inclination angles to be clamped, thereby improving the usability of the equipment.

[0016] 3. The swash plate grinding tooling for the swash plate pump utilizes the mutual engagement between the sector plate and the fixed frame, allowing the sector plate and the fixed frame at the bottom to rotate relative to each other, thereby driving the slide rod to slide inside the slide hole. The cooperation between the sector plate and the fixed frame prevents the swash plate from deflecting during the grinding process, resulting in poor grinding results. At the same time, by setting the slide rod and the slide hole, the fixed frame is placed on a horizontal plane.

[0017] Fourth, the swash plate grinding tooling used in the swash plate pump machining uses the swash plate to drive the round rod inside the central shaft hole to deflect, causing the round rod to drive the round plate to deflect. The round plate rotates on the ball. At this time, compression is generated between the limit plate at the top of the round plate and the fixed frame. The limit plate pushes the fixed frame to move, thereby driving the fan plate and the swash plate to rotate, so that the top of the swash plate is in a horizontal state. At the same time, the round plate is reset under the action of the elastic rope.

[0018] 5. The inclined plate grinding tooling for the inclined plate pump is equipped with a protective cover to prevent the debris generated by grinding from scattering in the working environment and polluting the air and the ground. At the same time, the debris falling on the bottom plate enters the lower hopper through the filter holes, which is convenient for the collection of debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The fixing seat 36 includes a base 361, which is fixedly connected to the top of the bottom plate 12. A fixing ring 362 is fixedly connected to the top of the base 361. An inclined groove 363 is provided on the outer side of the fixing ring 362.

[0037] The third embodiment, based on the first and second embodiments, see Figures 8 and 9 As shown, the limiting assembly 37 includes a cylinder 371, which is fixedly connected to the top of the base plate 12, and a ball 372 is fixedly connected to the end of the cylinder 371 away from the base plate 12. A circular plate 373 is provided inside the base 361. In the initial state, the elastic rope 374 is in a taut state. Under the pulling force of multiple elastic ropes 374, the circular plate 373 is in a horizontal state. When the top of the fixed swash plate is not in a horizontal state, the swash plate drives the round rod 381 inside the middle shaft hole to deviate, so that the round rod 381 drives the circular plate 373 to deviate, and the circular plate 373 rotates on the ball 372. At this time, the limiting plate 375 on the top of the circular plate 373 is squeezed with the fixed frame 31, and the limiting The plate 375 pushes the fixed frame 31 to move, thereby driving the fan-shaped plate 34 and the inclined plate 33 to rotate, so that the top of the inclined plate is in a horizontal state. At the same time, the circular plate 373 is reset under the action of the elastic rope 374. A groove is provided in the middle of the bottom of the circular plate 373. The circular plate 373 is rotatably connected to the outer side of the ball 372 through the groove. An elastic rope 374 is fixedly connected to the bottom edge of the circular plate 373. The end of the elastic rope 374 away from the circular plate 373 is fixedly connected to the bottom plate 12. The top of the circular plate 373 is fixedly connected to a limiting plate 375. There are two limiting plates 375. The two limiting plates 375 are symmetrically arranged with the cylinder 371 as the center. The limiting plate 375 is located inside the fixed frame 31.

[0038] The positioning member 38 includes a round rod 381, which is fixedly connected to the middle of the top of the circular plate 373.

When the swash plate is placed, the round rod 381 is located inside the central shaft hole on the swash plate, and extrusion is generated between the positioning plate 385 and the inner wall of the shaft hole of the swash plate. The positioning plate 385 is subjected to the extrusion force to drive the connecting rod 386 to move toward the direction of the limit block 383. At the same time, the return spring 387 is compressed. At this time, the positioning plate 385 is fixed to the inside of the shaft hole. The fixation of the outside and the inside improves the stability of the fixation. The connecting rod 386 is fixed to the limit block 38 3 applies force to move the two limit blocks 383 away from each other, and the mutual attraction between the two limit blocks 383 is used to fix the connecting rod 386 to prevent the connecting rod 386 from sliding during operation. There are two limit blocks 383, and the two limit blocks 383 are symmetrically arranged with the connecting rod 386 as the center. Circular grooves 384 are provided on opposite sides of the limit blocks 383.

[0039] When in use, the inclined end of the swash plate is placed downward so that the inclined side of the swash plate can contact the swash plate 33. The elastic performance of the compression spring 310 is used to make the swash plate 33 fit tightly with the swash plate. At the same time, the motor 39 is connected to an external power supply to work, and the motor 39 drives the connecting plate 322 to move in the direction of the swash plate, so that the connecting plate 322 drives the slider 321 to slide inside the slide groove 364. By providing three fixing members 32 and the swash plate 33, the swash plate is fixed and clamped according to the shape of the swash plate to improve the fixation. At the same time, the slider 321 drives the fixing block 323 to contact the outer side of the swash plate, and the contact plate 325 is forced to move on the fixing block 323. Under the elastic force of the spring plate 326, the contact plate 325 contacts the swash plate, and the elastic clamping prevents the clamping force from being too large to cause damage to the swash plate.

[0040] When the swash plate is placed, the round rod 381 is located inside the central shaft hole on the swash plate, and extrusion is generated between the positioning plate 385 and the inner wall of the shaft hole of the swash plate. The positioning plate 385 is subjected to the extrusion force to drive the connecting rod 386 to move toward the limit block 383. At the same time, the return spring 387 is compressed. At this time, the positioning plate 385 is fixed to the inside of the shaft hole. The fixation of the outside and the inside improves the stability of the fixation. The connecting rod 386 applies force to the limit block 383, so that the two limit blocks 383 move away from each other. The mutual attraction between the two limit blocks 383 is used to fix the limit block 383 to prevent the connecting rod 386 from sliding during operation.

[0041] When the top of the fixed swash plate is not in a horizontal state, the swash plate drives the round rod 381 inside the middle shaft hole to deviate, so that the round rod 381 drives the circular plate 373 to deviate, and the circular plate 373 rotates on the ball 372. At this time, the limiting plate 375 on the top of the circular plate 373 is squeezed with the fixed frame 31. The limiting plate 375 pushes the fixed frame 31 to move, thereby driving the fan-shaped plate 34 and the swash plate 33 to rotate, so that the top of the swash plate is in a horizontal state. At the same time, the circular plate 373 is reset under the action of the elastic rope 374.
