Description

Technical Field

[0001] The present invention relates to the technical field of swashplate processing, and specifically to a fixture for processing the swashplate of a swashplate pump. Background Art

[0002] The swashplate pump is a common type of hydraulic pump. With the continuous development of technology and the rapid progress of society, the application of swashplate pumps is increasing. The working principle of the swashplate pump is based on the angle change of the swashplate to control the reciprocating motion of the plunger, thereby realizing the processes of oil suction and oil discharge. It has the advantages of compact structure, high efficiency, and good flow uniformity. The performance characteristics of the swashplate pump play an important role in industrial production and mechanical engineering, providing a reliable hydraulic power source for the normal operation of various equipment. In practical applications, swashplate pumps are widely used in various hydraulic systems, such as construction machinery, machine tools, and automotive automatic transmissions. In construction machinery, the swashplate pump provides stable power support for the telescopic movement of the boom of a crane and the bucket movement of an excavator.

[0003] At present, when clamping and installing the swashplate of a swashplate pump, it is inconvenient to adjust the angle, which affects the overall use of the equipment. At the same time, during the overall operation of the equipment, vibrations will occur, resulting in instability of the overall mechanism and loosening. In severe cases, it will affect the overall clamping effect and is not conducive to the processing of the swashplate of the swashplate pump. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A fixture for processing the swashplate of a swashplate pump, comprising: A U-shaped frame, the U-shaped frame has a frame body with a supporting function, the opening of the U-shaped frame faces upward, and linear holes are respectively opened at corresponding positions at the bottom of the U-shaped frame; A feeding component, which is used to support and lift the swashplate material, and the feeding component is installed at both ends outside the U-shaped frame; Among them, the feeding component includes a support seat and a hydraulic cylinder. The bottom of the support seat is fixedly installed at the side of the inner wall bottom of the U-shaped frame. The hydraulic cylinder is hinged at the top outside the U-shaped frame. A feeding plate is rotatably installed on the top of the support seat. The output end of the hydraulic cylinder is hinged at the side of the outside of the feeding plate. A rectangular notch is opened at the middle of the bottom of the feeding plate. A centering module is installed at the middle of the outside of the feeding plate. By using the extension and contraction of the output end of the hydraulic cylinder and combining with the support seat to rotationally support the feeding plate, the feeding plate is driven to rotate and adjust the angle, making the angle adjustment convenient. Then, the swashplate material to be processed is placed on the feeding plate, and the swashplate material can be supported and lifted, thus facilitating subsequent clamping and fixing of the swashplate material; The blanking mechanism is used to press and fix the inclined disk material. The blanking mechanism is installed at the bottom of the inner wall of the U-shaped frame and close to the position of the linear hole; Among them, the blanking mechanism includes a cylinder. The cylinder is fixed at the bottom of the inner wall of the U-shaped frame, and the cylinder is installed at a position close to the middle of the U-shaped frame. The output end of the cylinder is fixedly installed with an H-shaped bracket. Both ends of the bottom of the H-shaped bracket are fixedly installed with C-shaped sliders. The C-shaped sliders are slidably installed at the side of the outside of the U-shaped frame. The bottom of the reinforcing rib in the middle of the H-shaped bracket is fixedly installed with a limiting slide bar. A pushing tooth is fixedly installed at the side of the outside of the limiting slide bar. The position of the pushing tooth corresponds to the position of the rectangular notch. The top of the H-shaped bracket is fixedly installed with a clamping component. By extending the output end of the cylinder and under the sliding connection of the C-shaped slider, the H-shaped bracket drives the clamping component and the pushing tooth to move together towards the position close to the blanking plate. Then, the pushing tooth can be inserted into the rectangular notch. By contacting the outside of the rectangular notch with the inner wall of the rectangular notch, the blanking plate can be supported, so that the blanking plate is not easily skewed, and the structures are fully utilized to interact with each other and connect the structures together.

[0005] Preferably, the blanking plate is installed obliquely to facilitate the placement of the inclined disk material. There are two hydraulic cylinders, and the two hydraulic cylinders are symmetrically installed along the central axis of the middle of the blanking plate. The two symmetrically arranged hydraulic cylinders apply a driving force to the blanking plate together, so that the blanking plate is balanced in force.

[0006] Preferably, an arc-shaped guide rail is fixedly installed at the bottom of the inner wall of the U-shaped frame and close to the support seat. The arc-shaped guide rail is installed directly below the blanking plate. Connecting rods are fixedly installed at the corresponding positions at the bottom of the blanking plate. Ball bearings are rotatably installed at the bottom ends of the connecting rods. The ball bearings are rotatably installed inside the arc-shaped guide rail. U-shaped notches are provided at both ends of the outside of the U-shaped frame and close to the hydraulic cylinders. By making the center of the arc-shaped guide rail coincide with the hinge point on the outside of the blanking plate, when the blanking plate rotates to adjust the angle, the connecting rods can be driven to rotate together. Under the rolling of the ball bearings, the connecting rods and the ball bearings act together, so that the blanking plate is supported by rolling, and thus the blanking plate is supported, and the structure is more stable during the rotation operation.

[0007] Preferably, the centering module includes a circular hole and a T-shaped connecting block. The circular hole is located in the middle of the outer side of the blanking plate. A groove is formed in the outer side of the blanking plate near the circular hole. The T-shaped connecting block is slidably installed between the groove and the blanking plate. A connecting square column is fixedly installed at the outer end of the T-shaped connecting block. The connecting square column is installed inside the circular hole. A pointed tapered tooth is fixedly installed at the outer end of the connecting square column. An annular spring is fixedly installed in the middle of the outer side of the connecting square column. By sleeving the central hole of the swashplate material on the pointed tapered tooth, the swashplate material can be supported by the pointed tapered tooth, so that the swashplate material is initially positioned and is not likely to slip.

[0008] Preferably, there are three T-shaped connecting blocks, and the three T-shaped connecting blocks are evenly distributed along the circumferential direction of the axis at the center of the circular hole, which is convenient for positioning the swashplate material. The positions of the T-shaped connecting blocks correspond to the positions of the connecting square columns.

[0009] Preferably, the pushing tooth and the cylinder are installed at the same height. The clamping assembly is installed directly above. The inner wall of the C-shaped slider fits with the side of the outer side of the U-shaped frame.

[0010] Preferably, the clamping assembly includes a mounting base. The bottom of the mounting base is fixedly installed with the top of the H-shaped bracket. A semi-circular clamping block is rotatably installed at the side of the top of the mounting base. A force-bearing clamping tooth is rotatably installed at the clamping surface of the outer side of the semi-circular clamping block. As the output end of the cylinder pushes the H-shaped bracket, the H-shaped bracket can drive the entire clamping assembly to move towards the side close to the blanking plate. The force-bearing clamping tooth can be used to contact the surface of the swashplate material. By applying a continuous pushing force at the output end of the cylinder, the swashplate material can be clamped and fixed.

[0011] Preferably, the mounting base is installed obliquely. There are two semi-circular clamping blocks, and the two semi-circular clamping blocks are symmetrically installed along the central axis in the middle of the mounting base. The force-bearing clamping teeth are evenly distributed at the clamping surface of the outer side of the semi-circular clamping block. By using the force-bearing clamping teeth to contact the surface of the swashplate material, multi-angle adjustment can be performed within the limit range of the arc-shaped guide rail to finely adjust the angle of the blanking plate. As the swashplate material is clamped, and the force-bearing clamping teeth can rotate by themselves, and at the same time, combined with the semi-circular clamping block that can rotate, the semi-circular clamping block can drive the force-bearing clamping teeth to rotate in the circumferential direction, so as to adapt to the uneven surface of the swashplate material. The semi-circular clamping block and the force-bearing clamping teeth act together to promote the adaptation between the structures and improve the clamping and fixing effect.

[0012] Preferably, a pressing mechanism is installed on the outer side of the feeding plate and near the rectangular notch. The pressing mechanism is installed on the side close to the hydraulic cylinder. The pressing mechanism includes a support plate, which is fixedly installed on the outer side of the feeding plate and near the rectangular notch. One end of the support plate away from the feeding plate is hinged with a fan-shaped swing plate. The top of the fan-shaped swing plate is fixedly installed with a zigzag connecting rod. The top of the zigzag connecting rod is fixedly installed with a pressing cone. A reset elastic strip is fixedly installed between the outer circular surface of the zigzag connecting rod and the outer side of the feeding plate. By using the pressing end of the pushing tooth to contact the fan-shaped swing plate, as the pushing tooth continuously moves, the fan-shaped swing plate is subjected to a pressing force, so that the fan-shaped swing plate can drive the zigzag connecting rod to rotate, and the reset elastic strip is compressed, so that the pressing cone moves towards the side close to the connecting square column, thereby applying a pressing force to the end of the connecting square column, facilitating subsequent clamping of the central hole of the swashplate material.

[0013] Preferably, the fan-shaped swing plate is installed obliquely, and the position of the fan-shaped swing plate corresponds to the position of the rectangular notch. The reset elastic strip is bent. When the pressing cone applies a pushing force to the end of the connecting square column, under the sliding connection of the T-shaped connecting block, the connecting square column drives the tip cone teeth to move in all directions, and the annular spring is stretched, and the tip cone teeth are expanded in all directions through three evenly distributed tip cone teeth, so that the surface of the tip cone teeth can contact the inner wall of the central hole of the swashplate material, thereby performing self-centering on the swashplate material, so that the swashplate material always remains in the middle, and it is helpful for mass production.

[0014] The present invention provides a fixture for machining the swashplate of a swashplate pump. It has the following beneficial effects: First, for the fixture for machining the swashplate of the swashplate pump, by using the elongation and contraction of the output end of the hydraulic cylinder and combining with the support seat to rotationally support the feeding plate, the feeding plate is driven to rotate and adjust the angle, so that the angle adjustment is convenient. Then, the swashplate material to be machined is placed on the feeding plate, and the swashplate material can be supported and lifted, thus facilitating subsequent clamping and fixing of the swashplate material.

[0015] Second, for the fixture for machining the swashplate of the swashplate pump, by making the center of the arc-shaped guide rail coincide with the hinge point on the outer side of the feeding plate, when the feeding plate rotates and adjusts the angle, the connecting rod can be driven to rotate, and under the rolling of the balls, the feeding plate can be supported by the combined action of the connecting rod and the balls, so that the feeding plate is supported and the structure is more stable during the rotational operation.

[0016] Third, for the fixture for machining the swashplate of the swashplate pump, by sleeving the central hole of the swashplate material on the tip cone teeth, the swashplate material can be supported by the tip cone teeth, so that the swashplate material is initially positioned and is not likely to slip.

[0017] IV. For the fixture for machining the swash plate of the swash plate pump, when the output end of the air cylinder extends and under the sliding connection of the C-shaped slider, the H-shaped bracket drives the clamping assembly and the pushing tooth to move together towards the position close to the feeding plate. Then, the pushing tooth can be inserted into the rectangular notch, and by contacting the outer side of the rectangular notch with the inner wall of the rectangular notch, the feeding plate can be supported, making it not easy for the feeding plate to be skewed.

[0018] V. For the fixture for machining the swash plate of the swash plate pump, when the top end of the pushing tooth contacts the fan-shaped swing plate and the pushing tooth continues to move, the fan-shaped swing plate is subjected to a top force. Then, the fan-shaped swing plate can drive the zigzag connecting rod to rotate, and the reset elastic strip is compressed. As a result, the top cone moves towards the side close to the connecting square column, thereby applying a top force to the end of the connecting square column, which is convenient for clamping the center hole of the swash plate material subsequently.

[0019] VI. For the fixture for machining the swash plate of the swash plate pump, under the sliding connection of the T-shaped connecting block, the connecting square column drives the tip cone teeth to move in all directions, and the annular spring is stretched. Through the three evenly distributed tip cone teeth expanding in all directions, the surface of the tip cone teeth can contact the inner wall of the center hole of the swash plate material, thereby performing self-centering on the swash plate material, making the swash plate material always remain in the middle, and contributing to batch production.

[0020] VII. For the fixture for machining the swash plate of the swash plate pump, as the output end of the air cylinder pushes the H-shaped bracket, the H-shaped bracket can drive the entire clamping assembly to move towards the side close to the feeding plate. Then, the stress clamping teeth can contact the surface of the swash plate material, and by applying a continuous pushing force from the output end of the air cylinder, the swash plate material can be clamped and fixed.

[0021] VIII. For the fixture for machining the swash plate of the swash plate pump, when clamping the swash plate material and using the stress clamping teeth that can rotate by themselves, and at the same time combined with the semi-circular clamping block that can rotate, the semi-circular clamping block can drive the stress clamping teeth to rotate in the circumferential direction. Thus, it can adapt to the uneven surface of the swash plate material. With the combined action of the semi-circular clamping block and the stress clamping teeth, the structure is promoted to be adapted to each other, improving the clamping and fixing effect.

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0025] The first embodiment, as Figures 1 - 5 shown, the present invention provides a technical solution: A fixture for machining the swash plate of a swash plate pump, comprising: A U-shaped frame 1, which has a supporting frame body, the opening of the U-shaped frame 1 is upward, and linear holes 2 are respectively opened at corresponding positions at the bottom of the U-shaped frame 1; A loading component 3, which is used to support and lift the swash plate material, and the loading component 3 is installed at both ends outside the U-shaped frame 1; Among them, the feeding component 3 includes a support base 31 and a hydraulic cylinder 33. The bottom of the support base 31 is fixedly installed at the side of the bottom inner wall of the U-shaped frame 1. The hydraulic cylinder 33 is hinged at the top of the outside of the U-shaped frame 1. A feeding plate 32 is rotatably installed on the top of the support base 31. The output end of the hydraulic cylinder 33 is hinged at the side of the outside of the feeding plate 32. A rectangular notch 34 is opened at the middle of the bottom of the feeding plate 32. A centering module 35 is installed at the middle of the outside of the feeding plate 32. The staff starts the hydraulic cylinder 33 to work, uses the extension and contraction of the output end of the hydraulic cylinder 33, and combines with the support base 31 to rotatably support the feeding plate 32, so as to drive the feeding plate 32 to rotate and adjust the angle, making the angle adjustment convenient. Then, place the swash plate material to be processed on the feeding plate 32, and the swash plate material can be supported and lifted. The feeding plate 32 is inclined for easy placement of the swash plate material. There are two hydraulic cylinders 33, and the two hydraulic cylinders 33 are symmetrically installed along the central axis of the middle of the feeding plate 32. The two symmetrical hydraulic cylinders 33 are used together to apply a driving force to the feeding plate 32, so that the feeding plate 32 is balanced in force.

[0026] An arc-shaped guide rail 36 is fixedly installed at the bottom of the inner wall of the U-shaped frame 1 and close to the support base 31. The arc-shaped guide rail 36 is installed directly below the feeding plate 32. Connecting rods 37 are fixedly installed at the corresponding positions at the bottom of the feeding plate 32. The bottom ends of the connecting rods 37 are rotatably installed with balls 38, and the balls 38 are rotatably installed inside the arc-shaped guide rail 36. U-shaped notches 39 are opened at both ends of the outside of the U-shaped frame 1 and close to the hydraulic cylinders 33. By making the center of the arc-shaped guide rail 36 coincide with the hinge point on the outside of the feeding plate 32, multi-angle adjustment is carried out within the limit range of the arc-shaped guide rail 36 to finely adjust the angle of the feeding plate 32. When the feeding plate 32 rotates and adjusts the angle, the connecting rods 37 can be driven to rotate together, and under the rolling of the balls 38, the connecting rods 37 and the balls 38 act together to make the feeding plate 32 receive rolling support, so that the feeding plate 32 is supported.

[0027] The centering module 35 includes a circular hole 351 and a T-shaped connecting block 352. The circular hole 351 is at the middle of the outside of the feeding plate 32. A groove is opened on the outside of the feeding plate 32 and close to the circular hole 351, and the T-shaped connecting block 352 is slidably installed with the feeding plate 32 through the groove. A connecting square column 353 is fixedly installed at the outer end of the T-shaped connecting block 352. The connecting square column 353 is installed inside the circular hole 351. A pointed tapered tooth 354 is fixedly installed at the outer end of the connecting square column 353. An annular spring 355 is fixedly installed at the middle of the outside of the connecting square column 353. By sleeving the central hole of the swash plate material on the pointed tapered tooth 354, the swash plate material can be supported by the pointed tapered tooth 354, so that the swash plate material is initially positioned.

[0028] There are three T-shaped connecting blocks 352, and the three T-shaped connecting blocks 352 are evenly distributed along the circumferential direction of the axis at the center of the circular hole 351, which is convenient for positioning the swashplate material. The positions of the T-shaped connecting blocks 352 correspond to the positions of the connecting square columns 353.

[0029] The second embodiment is as follows Figures 1 - 7 shown, based on the first embodiment: A pressing mechanism 4, which is used to press and fix the swashplate material. The pressing mechanism 4 is installed at the bottom of the inner wall of the U-shaped frame 1 and close to the position of the linear hole 2; Among them, the pressing mechanism 4 includes a cylinder 41. The cylinder 41 is fixed at the bottom of the inner wall of the U-shaped frame 1 and is installed close to the middle of the U-shaped frame 1. The output end of the cylinder 41 is fixedly installed with an H-shaped bracket 42. Both ends of the bottom of the H-shaped bracket 42 are fixedly installed with C-shaped sliders 43. The C-shaped sliders 43 are slidably installed at the side of the outside of the U-shaped frame 1. The bottom of the reinforcing rib in the middle of the H-shaped bracket 42 is fixedly installed with a limiting slide bar 44. A pushing tooth 45 is fixedly installed at the side of the outside of the limiting slide bar 44. The position of the pushing tooth 45 corresponds to the position of the rectangular notch 34. The top of the H-shaped bracket 42 is fixedly installed with a clamping assembly 46. The staff starts the cylinder 41 to work, uses the output end of the cylinder 41 to extend, and under the sliding connection of the C-shaped slider 43, the H-shaped bracket 42 drives the clamping assembly 46 and the pushing tooth 45 to move together towards the position close to the feeding plate 32, and then the pushing tooth 45 can be inserted into the rectangular notch 34. By using the contact between the outside of the rectangular notch 34 and the inner wall of the rectangular notch 34, the feeding plate 32 can be supported, so that the feeding plate 32 is not prone to skew.

[0030] The pushing tooth 45 and the cylinder 41 are installed at the same height, the clamping assembly 46 is installed directly above, and the inner wall of the C-shaped slider 43 fits the side of the outside of the U-shaped frame 1.

[0031] The clamping assembly 46 includes a mounting base 461. The bottom of the mounting base 461 is fixedly installed with the top of the H-shaped bracket 42. A semi-circular clamping block 462 is rotatably installed at the side of the top of the mounting base 461. A stress clamping tooth 463 is rotatably installed at the clamping surface outside the semi-circular clamping block 462. As the output end of the cylinder 41 pushes the H-shaped bracket 42, the H-shaped bracket 42 can drive the entire clamping assembly 46 to move towards the side close to the feeding plate 32, and then the stress clamping tooth 463 can be used to contact the surface of the swashplate material. By applying a continuous driving force with the output end of the cylinder 41, the swashplate material can be clamped and fixed.

[0032] The mounting base 461 is installed obliquely. There are two semi-circular clamping blocks 462, and the two semi-circular clamping blocks 462 are symmetrically installed along the central axis in the middle of the mounting base 461. The force-bearing clamping teeth 463 are evenly distributed on the clamping surface outside the semi-circular clamping blocks 462. The force-bearing clamping teeth 463 are used to contact the surface of the swashplate material. As the swashplate material is clamped, and the force-bearing clamping teeth 463 can rotate by themselves, and at the same time combined with the semi-circular clamping blocks 462 that can rotate, the semi-circular clamping blocks 462 can drive the force-bearing clamping teeth 463 to rotate in the circumferential direction, thereby adapting to the uneven surface of the swashplate material. By the combined action of the semi-circular clamping blocks 462 and the force-bearing clamping teeth 463, the adaptation between the structures is promoted, and the clamping and fixing effect is improved.

[0033] The third embodiment is as Figures 1 - 8 shown, based on the first embodiment and the second embodiment: A pressing mechanism 5 is installed outside the discharging plate 32 and near the rectangular notch 34. The pressing mechanism 5 is installed on one side close to the hydraulic cylinder 33. The pressing mechanism 5 includes a support plate 51. The support plate 51 is fixedly installed outside the discharging plate 32 and near the rectangular notch 34. One end of the support plate 51 away from the discharging plate 32 is hinged with a sector-shaped swing plate 52. The top end of the sector-shaped swing plate 52 is fixedly installed with a zigzag connecting rod 53. The top end of the zigzag connecting rod 53 is fixedly installed with a pressing cone 54. A reset elastic strip 55 is fixedly installed between the outer circumferential surface of the zigzag connecting rod 53 and the outside of the discharging plate 32. When the pushing tooth 45 is inserted into the rectangular notch 34, the pushing end of the pushing tooth 45 is used to contact the sector-shaped swing plate 52. As the pushing tooth 45 continuously moves, the sector-shaped swing plate 52 is subjected to a pushing force, and the sector-shaped swing plate 52 can be used to drive the zigzag connecting rod 53 to rotate, and the reset elastic strip 55 is compressed, so that the pressing cone 54 moves toward the side close to the connecting square column 353, thereby applying a pushing force to the end of the connecting square column 353.

[0034] The sector-shaped swing plate 52 is installed obliquely. The position of the sector-shaped swing plate 52 corresponds to the position of the rectangular notch 34. The reset elastic strip 55 is in a bent shape. When the pressing cone 54 applies a pushing force to the end of the connecting square column 353, under the sliding connection of the T-shaped connecting block 352, the connecting square column 353 drives the tip tapered tooth 354 to move in all directions, and the annular spring 355 is stretched, and expands in all directions through the three evenly distributed tip tapered teeth 354. The surface of the tip tapered tooth 354 can be used to contact the inner wall of the central hole of the swashplate material, thereby self-centering the swashplate material and keeping the swashplate material always in the middle.

[0035] During use, first, the staff member starts the hydraulic cylinder 33 to work. By using the elongation of the output end of the hydraulic cylinder 33 and combining with the support base 31 to rotatably support the material discharging plate 32, the material discharging plate 32 is driven to rotate and adjust the angle, making the angle adjustment convenient. Then, the swash plate material to be processed is placed on the material discharging plate 32, and the swash plate material can be supported and lifted. By sleeving the central hole of the swash plate material on the tip conical tooth 354, the swash plate material can be supported by the tip conical tooth 354, enabling the swash plate material to be initially positioned; And by making the center of the arc-shaped guide rail 36 coincide with the hinge point on the outside of the material discharging plate 32, multi-angle adjustment can be performed within the limit range of the arc-shaped guide rail 36 to finely adjust the angle of the material discharging plate 32. When the material discharging plate 32 rotates and adjusts the angle, the connecting rod 37 can be driven to rotate. Under the rolling of the ball 38, the combined action of the connecting rod 37 and the ball 38 enables the material discharging plate 32 to be supported by rolling, thus supporting the material discharging plate 32; At this time, the staff member starts the cylinder 41 to work. By using the elongation of the output end of the cylinder 41 and under the sliding connection of the C-shaped slider 43, the H-shaped bracket 42 drives the clamping assembly 46 and the pushing tooth 45 to move together towards the position closer to the material discharging plate 32. The pushing tooth 45 can be inserted into the rectangular notch 34. By making the outside of the rectangular notch 34 contact with the inner wall of the rectangular notch 34, the material discharging plate 32 can be supported, preventing the material discharging plate 32 from being skewed easily; And when the pushing tooth 45 is inserted into the rectangular notch 34, the top end of the pushing tooth 45 contacts the sector-shaped swing plate 52. As the pushing tooth 45 continues to move, the sector-shaped swing plate 52 is subjected to a pushing force, enabling the sector-shaped swing plate 52 to drive the zigzag connecting rod 53 to rotate, and the reset elastic strip 55 is compressed. As a result, the top cone 54 moves towards the side closer to the connecting square column 353, thereby applying a pushing force to the end of the connecting square column 353; Meanwhile, under the sliding connection of the T-shaped connecting block 352, the connecting square column 353 drives the tip conical tooth 354 to move in all directions. The annular spring 355 is stretched, and the three evenly distributed tip conical teeth 354 expand in all directions. The surface of the tip conical tooth 354 can be made to contact the inner wall of the central hole of the swash plate material, thereby performing self-centering on the swash plate material and keeping the swash plate material always in the middle; Moreover, as the output end of the cylinder 41 pushes the H-shaped bracket 42, the H-shaped bracket 42 drives the entire clamping assembly 46 to move towards the side closer to the material discharging plate 32, By using the force-bearing clamping teeth 463 to contact the surface of the inclined disk material, and as the inclined disk material is clamped, and by using the fact that the force-bearing clamping teeth 463 can rotate by themselves, and combined with the fact that the semi-circular clamping block 462 can rotate, the semi-circular clamping block 462 can drive the force-bearing clamping teeth 463 to rotate in the circumferential direction, thereby adapting to the uneven surface of the inclined disk material. By the combined action of the semi-circular clamping block 462 and the force-bearing clamping teeth 463, the adaptation between structures is promoted, and the clamping and fixing effect is improved. By using the force-bearing clamping teeth 463 to contact the surface of the inclined disk material, a continuous driving force can be applied by the output end of the air cylinder 41, and thus the inclined disk material can be clamped and fixed.
