Technical Field

[0001] The present invention relates to the technical field of swash plate processing, in particular to a clamp for processing the swash plate of a swash plate pump. Background Art

[0002] Swash plate pumps are a common type of hydraulic pump. With the continuous advancement of science and technology and the rapid progress of society, their application is increasing. The operating principle of a swash plate pump is to control the reciprocating motion of the plunger by changing the angle of the swash plate, thereby achieving the oil suction and discharge process. It has advantages such as compact structure, high efficiency, and good flow uniformity. The performance characteristics of swash plate pumps make them 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, swash plate pumps are widely used in various hydraulic systems, such as construction machinery, machine tools, and automatic transmissions in automobiles. In construction machinery, swash plate pumps provide stable power support for crane boom extension and retraction, excavator bucket movement, and other applications.

[0003] At present, when the existing swash plate of the swash plate pump is processed and clamped, it is inconvenient to adjust the angle, which affects the use of the entire equipment. At the same time, when the entire equipment is running, vibration will be generated, resulting in the overall instability of the mechanism and looseness. In serious cases, it will affect the overall clamping effect and is not conducive to the processing of the swash plate of the swash plate pump. Summary of the Invention

[0006] The discharge assembly is used to support and lift the material on the swash plate, and the discharge assembly is installed at both ends of the outer side of the U-shaped frame;

[0007] The discharging assembly comprises a support seat and a hydraulic cylinder, the bottom of the support seat is fixedly installed at the edge of the bottom wall of the inner wall of the U-shaped frame, the hydraulic cylinder is hinged to the top end of the outer side of the U-shaped frame, and a discharging plate is rotatably installed on the top of the support seat, and the output end of the hydraulic cylinder is hinged to the edge of the outer side of the discharging plate, and a rectangular notch is opened in the middle of the bottom of the discharging plate, and a centering module is installed in the middle of the outer side of the discharging plate. The discharging plate is rotated and supported by the extension and contraction of the output end of the hydraulic cylinder and combined with the support seat, so that the discharging plate is driven to rotate and adjust the angle, making the angle adjustment convenient, and then the inclined plate material to be processed is placed on the discharging plate, so that the inclined plate material can be supported and lifted, thereby facilitating the subsequent clamping and fixing of the inclined plate material;

[0008] A pressing mechanism, which is used to press and fix the material on the swash plate, and is installed at the bottom of the inner wall of the U-shaped frame and close to the straight hole;

[0009] The H-shaped bracket can be inserted into the inner wall of the U-shaped bracket by the push tooth, and the outer wall of the H-shaped bracket can be supported by the push tooth, so that the H-shaped bracket is not easily skewed, and the interaction between the structures is fully utilized to connect the structures together.

[0010] Preferably, the discharge plate is installed at an angle to facilitate the placement of materials on the inclined plate. There are two hydraulic cylinders, and the two hydraulic cylinders are installed symmetrically along the central axis in the middle of the discharge plate. The two symmetrical hydraulic cylinders are used to apply a pushing force to the discharge plate so that the force on the discharge plate is balanced.

[0011] Preferably, an arc guide rail is fixedly installed at the bottom of the inner wall of the U-shaped frame and near the support seat, and the arc guide rail is installed just below the discharge plate, and a connecting rod is fixedly installed at the corresponding position of the bottom of the discharge plate, and a ball is rotatably installed at the bottom end of the connecting rod, and the ball is rotatably installed inside the arc guide rail, and U-shaped notches are provided at both ends of the outer side of the U-shaped frame and near the hydraulic cylinder. By coinciding with the center of the arc guide rail and the hinge point of the outer side of the discharge plate, the discharge plate can be used to drive the connecting rod to rotate when adjusting the angle, and under the rolling of the ball, the connecting rod and the ball can work together to make the discharge plate subject to rolling support, thereby making the discharge plate supported, and the structure is more stable during rotation.

[0012] Preferably, the centering module includes a circular hole and a T-shaped connecting block, a groove is provided on the outside of the discharge plate and close to the circular hole in the middle of the outer side of the circular hole discharge plate, and the T-shaped connecting block is slidably installed between the groove and the discharge plate, and a connecting square column is fixedly installed on the end of the outer side of the T-shaped connecting block, and the connecting square column is installed inside the circular hole, and a pointed conical tooth is fixedly installed on the end of the outer side of the connecting square column, and an annular spring is fixedly installed in the middle of the outer side of the connecting square column, and the center hole of the inclined plate material is sleeved on the pointed conical tooth, so that the pointed conical tooth can be used to support the inclined plate material, so that the inclined plate material is initially positioned and not prone to slipping.

[0013] 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 inclined plate material, and the position of the T-shaped connecting block corresponds to the position of the connecting square column.

[0014] Preferably, the pushing teeth and the cylinder are installed at the same height, the clamping assembly is installed directly above them, and the inner wall of the C-shaped slider is in contact with the side of the outer side of the U-shaped frame.

[0015] Preferably, the clamping assembly includes a mounting base, the bottom of the mounting base is fixedly mounted to the top of the H-shaped bracket, a semicircular clamping block is rotatably mounted on the side of the top of the mounting base, and a force-bearing clamping tooth is rotatably mounted on the clamping surface of the outer side of the semicircular clamping block. As the output end of the cylinder pushes the H-shaped bracket, the H-shaped bracket can drive the clamping assembly as a whole to move toward the side close to the discharge plate, and the force-bearing clamping teeth can be used to contact the surface of the inclined plate material, and the output end of the cylinder can be used to apply a continuous pushing force to clamp and fix the inclined plate material.

[0016] Preferably, the mounting base is installed at an angle, and there are two semicircular clamping blocks, and the two semicircular clamping blocks are symmetrically installed along the central axis in the middle of the mounting base, and the force-bearing clamping teeth are evenly distributed on the clamping surface on the outside of the semicircular clamping block. The force-bearing clamping teeth are in contact with the surface of the inclined plate material, and multi-angle adjustment is performed within the limit range of the arc guide rail to fine-tune the angle of the discharge plate. As the inclined plate material is clamped and the force-bearing clamping teeth themselves can be rotated, combined with the rotation of the semicircular clamping block, the semicircular clamping block can drive the force-bearing clamping teeth to rotate in a circumferential direction, thereby adapting to the uneven surface of the inclined plate material, and utilizing the semicircular clamping block and the force-bearing clamping teeth to work together to promote adaptation between structures and improve the clamping and fixing effect.

[0017] The top of the support plate is hinged on the top of the support plate and the top of the support plate is fixedly installed with a fan-shaped swing plate, and the top of the fan-shaped swing plate is fixedly installed with a bending connecting rod, and the top of the bending connecting rod is fixedly installed with a pushing cone, and a reset elastic strip is fixedly installed between the outer circular surface of the bending connecting rod and the outer side of the discharge plate, and the pushing end of the pushing tooth contacts the fan swing plate. As the pushing tooth continues to move, the fan swing plate is subjected to a pushing force, and the fan swing plate can be used to drive the bending connecting rod to rotate, and the reset elastic strip is compressed, so that the pushing cone moves toward the side close to the connecting square column, thereby applying a pushing force to the end of the connecting square column, so as to facilitate the subsequent clamping of the center hole of the inclined plate material.

[0018] Preferably, the fan-shaped swing plate is installed at an angle, and the position of the fan-shaped swing plate corresponds to the position of the rectangular notch. The reset elastic strip is curved. When the top cone applies a pushing force to the end of the connecting square column, the connecting square column drives the tip conical teeth to move in all directions under the sliding connection of the T-shaped connecting block, and the annular spring is stretched and expands in all directions through three evenly distributed tip conical teeth. The surface of the tip conical teeth can be used to contact the inner wall of the center hole of the inclined plate material, thereby self-centering the inclined plate material, so that the inclined plate material is always kept in the middle, and it is conducive to mass production.

[0019] The present invention provides a fixture for machining the swash plate of a swash plate pump. It has the following beneficial effects:

[0020] 1. The swash plate processing fixture of the swash plate pump utilizes the extension and contraction of the hydraulic cylinder output end and the support seat to rotate and support the discharge plate, thereby driving the discharge plate to rotate and adjust the angle, making angle adjustment convenient. The swash plate material to be processed is then placed on the discharge plate, which can support and lift the swash plate material, thereby facilitating the subsequent clamping and fixing of the swash plate material.

[0021] Second, the jig for machining the swash plate of the swash plate pump utilizes the center of the arc guide rail to coincide with the hinge point on the outside of the discharge plate. This allows the discharge plate to be rotated to adjust its angle by driving a connecting rod to rotate. Furthermore, the connecting rod and the ball work together to provide rolling support for the discharge plate, thereby supporting the discharge plate and making the structure more stable during rotation.

[0022] 3. The swash plate processing fixture of the swash plate pump utilizes the center hole of the swash plate material to be sleeved on the tip conical teeth, so that the tip conical teeth can support the swash plate material, so that the swash plate material is initially positioned and not easy to slip.

[0023] Fourth, the jig for machining the swash plate of the swash plate pump utilizes the extension of the output end of the cylinder, and under the sliding connection of the C-shaped slider, the H-shaped bracket drives the clamping assembly and the push teeth to move together toward the position close to the discharge plate. The push teeth can then be inserted into the rectangular notch, and the outer side of the rectangular notch contacts the inner wall of the rectangular notch to support the discharge plate, making it less likely to skew.

[0024] 5. The jig for machining the swash plate of the swash plate pump utilizes the pushing end of the pushing tooth to contact the fan-shaped swing plate. As the pushing tooth continues to move, the fan-shaped swing plate is subjected to a pushing force, which can then be used to drive the zigzag connecting rod to rotate, and the reset elastic strip is compressed, causing the pushing cone to move toward the side close to the connecting square column, thereby applying a pushing force to the end of the connecting square column, facilitating the subsequent clamping of the center hole of the swash plate material.

[0025] 6. The swash plate machining fixture for this swash plate pump utilizes a sliding connection via a T-shaped connecting block, allowing the connecting square column to move the tapered teeth in all directions. This stretches the annular spring, expanding it in all directions through three evenly spaced tapered teeth. The surfaces of the tapered teeth contact the inner wall of the center hole of the swash plate material, self-centering the swash plate material and ensuring it remains centered. This facilitates mass production.

[0026] 7. The swash plate processing fixture of the swash plate pump, as the output end of the cylinder pushes the H-shaped bracket, can drive the H-shaped bracket to move the clamping assembly as a whole toward the side close to the discharge plate, so that the stressed clamping teeth can contact the surface of the swash plate material, and the output end of the cylinder can apply a continuous pushing force to clamp and fix the swash plate material.

[0027] 8. The swash plate processing fixture of the swash plate pump clamps the swash plate material and uses the force-bearing clamping teeth to rotate. At the same time, the semicircular clamping block can rotate, so that the semicircular clamping block can drive the force-bearing clamping teeth to rotate in the circumferential direction, thereby adapting to the uneven surface of the swash plate material. The semicircular clamping block and the force-bearing clamping teeth work together to promote the adaptation between the structures and improve the clamping and fixing effect.

[0045] 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 inclined plate material. The position of the T-shaped connecting block 352 corresponds to the position of the connecting square column 353 .

[0046] The second embodiment, as Figure 1-Figure 7 As shown, based on the first embodiment:

[0047] The pressing mechanism 4 is used to press and fix the material on the swash plate. The pressing mechanism 4 is installed at the bottom of the inner wall of the U-shaped frame 1 and close to the straight hole 2;

[0048] Among them, the pressing mechanism 4 includes a cylinder 41, which is fixed to the bottom of the inner wall of the U-shaped frame 1, and the cylinder 41 is installed near the middle of the U-shaped frame 1. The output end of the cylinder 41 is fixedly installed with an H-shaped bracket 42, and both ends of the bottom of the H-shaped bracket 42 are fixedly installed with a C-shaped slider 43. The C-shaped slider 43 is slidably installed with the side of the outer side of the U-shaped frame 1. The bottom of the reinforcement rib in the middle of the H-shaped bracket 42 is fixedly installed with a limited slide 44. The side of the outer side of the limited slide 44 is fixedly installed with a pushing tooth 45. The position of the pushing tooth 45 is consistent with the rectangular The position of the notch 34 corresponds to that of the clamping assembly 46, and the top of the H-shaped bracket 42 is fixedly installed. The staff turns on the cylinder 41 to work, and 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 to a position close to the discharge plate 32, and the pushing tooth 45 can be used to insert into the rectangular notch 34, and the outer side of the rectangular notch 34 is in contact with the inner wall of the rectangular notch 34, so that the discharge plate 32 can be supported, so that the discharge plate 32 is not easily skewed.

[0049] The pushing teeth 45 and the cylinder 41 are installed at the same height, the clamping assembly 46 is installed directly above them, and the inner wall of the C-shaped slider 43 is in contact with the side of the outer side of the U-shaped frame 1.

[0050] The clamping assembly 46 includes a mounting base 461, the bottom of the mounting base 461 is fixedly mounted on the top of the H-shaped bracket 42, a semicircular clamping block 462 is rotatably mounted on the side of the top of the mounting base 461, and a force-bearing clamping tooth 463 is rotatably mounted on the clamping surface of the outer side of the semicircular 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 clamping assembly 46 as a whole to move toward the side close to the discharge plate 32, and the force-bearing clamping tooth 463 can be used to contact the surface of the inclined plate material, and the output end of the cylinder 41 can be used to apply a continuous pushing force to clamp and fix the inclined plate material.

[0051] The mounting base 461 is installed at an angle, and there are two semicircular clamping blocks 462, and the two semicircular clamping blocks 462 are symmetrically installed along the central axis in the middle of the mounting base 461, and the force-bearing clamping teeth 463 are evenly distributed on the clamping surface on the outside of the semicircular clamping block 462. The force-bearing clamping teeth 463 are used to contact the surface of the inclined plate material, and as the inclined plate material is clamped, the force-bearing clamping teeth 463 themselves can be rotated. At the same time, combined with the rotation of the semicircular clamping block 462, the semicircular clamping block 462 can drive the force-bearing clamping teeth 463 to rotate in a circular direction, thereby adapting to the uneven surface of the inclined plate material, and using the semicircular clamping block 462 and the force-bearing clamping teeth 463 to work together to promote adaptation between structures and improve the clamping and fixing effect.

[0052] The third embodiment, as Figures 1-8 As shown, based on the first and second embodiments:

[0053] The outer side of the discharge plate 32 and the position close to the rectangular notch 34 is provided with a pressing mechanism 5, which is provided on the side close to the hydraulic cylinder 33. The pressing mechanism 5 includes a support plate 51, which is fixed to the outer side of the discharge plate 32 and the position close to the rectangular notch 34. The end of the support plate 51 away from the discharge plate 32 is hinged with a fan-shaped swing plate 52, and the top of the fan-shaped swing plate 52 is fixedly provided with a zigzag connecting rod 53, and the top of the zigzag connecting rod 53 is fixedly provided with a jacking cone 54. The outer surface of the zigzag connecting rod 53 is fixedly provided with a jacking cone 54. A reset elastic strip 55 is fixedly installed between the outer side of the discharge plate 32. When the pushing tooth 45 is inserted into the rectangular notch 34, the pushing end of the pushing tooth 45 contacts the fan-shaped swing plate 52. As the pushing tooth 45 continues to move, the fan-shaped swing plate 52 is subjected to a pushing force, and the fan-shaped swing plate 52 can be used to drive the bending connecting rod 53 to rotate, and the reset elastic strip 55 is compressed, so that the pushing 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.

[0054] The fan-shaped swing plate 52 is installed at an angle, and the position of the fan-shaped swing plate 52 corresponds to the position of the rectangular notch 34. The reset elastic strip 55 is curved. When the top cone 54 applies a pushing force to the end of the connecting square column 353, the sliding connection of the T-shaped connecting block 352 causes the connecting square column 353 to drive the tip conical teeth 354 to move in all directions, and the annular spring 355 is stretched and expands in all directions through three evenly distributed tip conical teeth 354. The surface of the tip conical teeth 354 can be used to contact the inner wall of the center hole of the swash plate material, thereby self-centering the swash plate material, so that the swash plate material is always kept in the middle.

[0055] When in use, the staff first starts the hydraulic cylinder 33 to work, and uses the extension of the output end of the hydraulic cylinder 33 and the support seat 31 to rotate and support the discharge plate 32, thereby driving the discharge plate 32 to rotate and adjust the angle, making the angle adjustment convenient. Then, the swash plate material to be processed is placed on the discharge plate 32, which can support and lift the swash plate material. The center hole of the swash plate material is placed on the tip conical teeth 354, and the tip conical teeth 354 can be used to support the swash plate material, so that the swash plate material is initially positioned.

[0056] The center of the arc guide rail 36 coincides with the hinge point on the outside of the discharge plate 32, and multiple angles can be adjusted within the limit range of the arc guide rail 36 to fine-tune the angle of the discharge plate 32. When the discharge plate 32 is rotated to adjust the angle, the connecting rod 37 can be driven to rotate. Under the rolling of the ball 38, the connecting rod 37 and the ball 38 can work together to support the discharge plate 32 in a rolling manner, thereby supporting the discharge plate 32.

[0057] At this time, the staff starts the cylinder 41 to work, and uses the output end of the cylinder 41 to extend. 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 to a position close to the discharge plate 32. The pushing tooth 45 can then be inserted into the rectangular notch 34. The outer side of the rectangular notch 34 contacts the inner wall of the rectangular notch 34, thereby supporting the discharge plate 32 and preventing the discharge plate 32 from being skewed.

[0058] When the pushing tooth 45 is inserted into the rectangular notch 34, the pushing end of the pushing tooth 45 contacts the fan-shaped swing plate 52. As the pushing tooth 45 continues to move, the fan-shaped swing plate 52 is subjected to a pushing force, which can then drive the zigzag connecting rod 53 to rotate, and the return elastic strip 55 is compressed, so that the pushing 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.

[0059] At the same time, the sliding connection of the T-shaped connecting block 352 causes the connecting square column 353 to move the pointed conical teeth 354 in all directions, and the annular spring 355 is stretched and expanded in all directions through the three evenly distributed pointed conical teeth 354. The surfaces of the pointed conical teeth 354 can then contact the inner wall of the center hole of the swash plate material, thereby self-centering the swash plate material and keeping it in the middle at all times.

[0060] Moreover, as the output end of the cylinder 41 pushes the H-shaped bracket 42, the H-shaped bracket 42 drives the clamping assembly 46 to move as a whole toward the side close to the discharge plate 32.

[0061] By utilizing the stressed clamping teeth 463 to contact the surface of the swash plate material and clamping the swash plate material, and utilizing the stressed clamping teeth 463 to rotate itself, and simultaneously combining with the rotation of the semicircular clamping block 462, the semicircular clamping block 462 can drive the stressed clamping teeth 463 to rotate in the circumferential direction, thereby adapting to the uneven surface of the swash plate material. The semicircular clamping block 462 and the stressed clamping teeth 463 work together to promote the adaptation between the structures and improve the clamping and fixing effect.

[0062] By utilizing the contact between the force-bearing clamping teeth 463 and the surface of the swash plate material, the output end of the cylinder 41 can be utilized to apply a continuous driving force, thereby clamping and fixing the swash plate material.

[0063] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
