Description

Technical Field

[0001] This utility model relates to the field of machining tooling fixtures, and in particular to a precision positioning multi-station industrial pump cover machining tooling fixture. Background Technology

[0002] In modern industrial manufacturing, industrial pumps are core equipment for fluid transportation, and the machining accuracy of their pump covers directly affects the sealing performance, operational stability, and service life of the pump body. As industrial production continues to increase the performance requirements of pump equipment, the structural design of pump covers is becoming increasingly complex, and the need for multi-station machining is becoming more common, placing higher demands on the precise positioning capabilities, adaptability, and automation level of tooling fixtures.

[0003] In existing technologies, the tooling fixtures commonly used in the machining of industrial pump covers mostly employ rigid clamping mechanisms. Their technical principle is primarily based on a combination of fixed-size positioning blocks and manually or pneumatically driven clamping devices. Initial positioning is typically achieved by engaging pre-set positioning pins with the process holes of the pump cover, followed by securing the workpiece on the worktable using bolts, hydraulic cylinders driving pressure plates, or eccentric wheels. The positioning reference and clamping force of these fixtures need to be pre-adjusted according to the specific pump cover model, and corresponding positioning components and clamping parts must be replaced when machining workpieces of different specifications.

[0004] However, the rigid clamping structure of the existing technology has significant limitations. Its clamping size and positioning parameters are fixed and cannot be automatically adjusted to adapt to the slight changes in size or shape of the workpiece caused by material characteristics, processing errors and other factors during the manufacturing process. This leads to problems such as positioning offset and unstable clamping of the workpiece during processing, which ultimately affects the processing accuracy of the pump cover. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a precision positioning multi-station industrial pump cover machining tooling fixture, which aims to improve the problem of decreased machining accuracy caused by the inability to automatically adjust to adapt to slight changes in workpiece size or shape.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision positioning multi-station industrial pump cover processing tooling fixture, including a base, a support column fixedly connected to the top of the base, a support plate fixedly connected to the side wall of the base, and a clamping assembly provided on the inner wall of the support plate;

[0007] The clamping assembly includes a cylinder, the side wall of which is fixedly connected to the inner wall of the support plate, the output end of which is fixedly connected to a first trapezoidal plate, the top of the support column is fixedly connected to a slide rail, the outer wall of the slide rail is slidably connected to a second trapezoidal plate, the top of the second trapezoidal plate is provided with an adaptive component, the bottom of the second trapezoidal plate is slidably connected to the side wall of the first trapezoidal plate, and the bottom of the support column is provided with a spring-loaded component.

[0008] As a further description of the above technical solution:

[0009] The rebound assembly includes a fixing block, the top of which is fixedly connected to the bottom of the support column. A first spring is provided on the side wall of the fixing block, one end of which is fixedly connected to the side wall of the fixing block, and the other end of which is fixedly connected to the side wall of the second trapezoidal plate.

[0010] As a further description of the above technical solution:

[0011] The adaptive component includes a hollow block, the bottom of which is fixedly connected to the inside of a second trapezoidal plate. A second spring is provided on the inner wall of the hollow block, one end of which is fixedly connected to the inner wall of the hollow block, and the other end of which is fixedly connected to a connecting column. The outer wall of the connecting column is slidably connected to the inside of the hollow block.

[0012] As a further description of the above technical solution:

[0013] A connecting plate is fixedly connected to the top of the support column, and a slot is provided inside the connecting plate.

[0014] As a further description of the above technical solution:

[0015] A sliding plate is slidably connected to the side wall of the connecting plate, and a soft block is fixedly connected to the side wall of the sliding plate. The side wall of the soft block is slidably connected to the inner wall of the connecting plate.

[0016] As a further description of the above technical solution:

[0017] A hollow column is fixedly connected inside the sliding plate, and a ball is slidably connected to the inner wall of the hollow column.

[0018] As a further description of the above technical solution:

[0019] A third spring is provided on the inner wall of the hollow column, and both ends of the third spring are fixedly connected to the outer wall of the ball.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the ball is slidably connected to the inner wall of the slot, and the outer wall of the ball is slidably connected to the inner wall of the connecting plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the first trapezoidal plate is driven to move by a cylinder. Then, the movement of the first trapezoidal plate causes its side wall to push the second trapezoidal plate to slide on the outer wall of the slide rail. At the same time, the second trapezoidal plate can be pushed back by the first spring to reset the second trapezoidal plate, thus achieving the effect of adaptive clamping of the workpiece. This solves the problem that the workpiece cannot be automatically adjusted to adapt to small changes in size or shape, which leads to a decrease in processing accuracy. It also improves the diversity of tooling fixtures for processing industrial pump covers.

[0024] 2. In this utility model, by pushing the sliding plate, the soft block is moved to slide on the side wall of the connecting plate. At the same time, the hollow column is moved along with the sliding plate during the process of being stressed. Then, during the movement of the hollow column, the clamping ball is moved to move on the inner wall of the hollow column. Then, the movement of the clamping ball will compress the third spring, which achieves the effect of preventing the workpiece from leaving the clamping range. This solves the problem of workpiece instability caused by leaving the clamping range, and improves the stability of the tooling fixture for processing industrial pump covers.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a precision positioning multi-station industrial pump cover processing tooling fixture, including a base 1, a support column 2 fixedly connected to the top of the base 1, a support plate 3 fixedly connected to the side wall of the base 1, and a clamping component provided on the inner wall of the support plate 3.

[0035] The clamping assembly includes a cylinder 5, which drives the first trapezoidal plate 6 to move horizontally, thereby providing a power source for the clamping action, realizing the subsequent force conversion and transmission, and providing a driving force basis for workpiece clamping. The side wall of the cylinder 5 is fixedly connected to the inner wall of the support plate 3, and the output end of the cylinder 5 is fixedly connected to the first trapezoidal plate 6. The first trapezoidal plate 6 cooperates with the second trapezoidal plate 7 to perform force conversion movement. The inclined side wall of the first trapezoidal plate 6 contacts the inclined surface at the bottom of the second trapezoidal plate 7, converting the horizontal driving force into a lateral thrust perpendicular to the workpiece direction, achieving the effect of pushing the second trapezoidal plate 7 to slide along the slide rail 12. The top of the support column 2 is fixedly connected to the slide rail 12, and the outer wall of the slide rail 12 is slidably connected to the second trapezoidal plate 7. The top of the second trapezoidal plate 7 is provided with an adaptive component, and the bottom of the second trapezoidal plate 7 is slidably connected to the side wall of the first trapezoidal plate 6. The bottom of the support column 2 is provided with a spring-rebound component, which includes a fixing block 8. The top of the fixing block 8 is fixedly connected to the bottom of the support column 2, and the side wall of the fixing block 8 is provided with a first spring 9. The first spring 9 is used to move the second trapezoidal plate 7... The device stores elastic potential energy during sliding. When cylinder 5 resets, it releases the potential energy to pull the second trapezoidal plate 7 to slide in the opposite direction, thereby cooperating with the adaptive component to achieve the clamping action of the workpiece and ensure the reliability of clamping. One end of the first spring 9 is fixedly connected to the side wall of the fixed block 8, and the other end of the first spring 9 is fixedly connected to the side wall of the second trapezoidal plate 7. The adaptive component includes a hollow block 4. The bottom of the hollow block 4 is fixedly connected to the inside of the second trapezoidal plate 7. A second spring 10 is provided on the inner wall of the hollow block 4. One end of the second spring 10 is fixedly connected to the inner wall of the hollow block 4, and the other end of the second spring 10 is fixedly connected to a connecting post 11. The connecting post 11 is used to contact the surface of the workpiece. When subjected to the pressure of the workpiece, it slides along the inner wall of the hollow block 4 and compresses the second spring 10, thereby converting the pressure of the workpiece on the fixture into the elastic potential energy of the spring, realizing the flexible clamping of the workpiece. The outer wall of the connecting post 11 is slidably connected to the inside of the hollow block 4. The adaptive component consists of a hollow block 4, a second spring 10 and a connecting post 11, which achieves the effect of compensating for small errors in the size of the workpiece. Further details are omitted here. The second spring 10 is used to provide elastic force when the connecting column 11 slides under the pressure of the workpiece, thereby compensating for small errors in the size of the workpiece through elastic force, ensuring uniform and stable clamping force, and avoiding workpiece deformation caused by rigid contact.

[0036] Reference Figure 5 and Figure 6A connecting plate 13 is fixedly connected to the top of the support column 2. A slot 16 is provided inside the connecting plate 13. A sliding plate 15 is slidably connected to the side wall of the connecting plate 13. A soft block 14 is fixedly connected to the side wall of the sliding plate 15. The soft block 14 is used to contact the workpiece surface, thereby achieving initial positioning of the workpiece. Simultaneously, the elastic contact of the soft block 14 further buffers the clamping stress, improves positioning accuracy, and avoids damage to the workpiece surface caused by rigid contact. The side wall of the soft block 14 is slidably connected to the inner wall of the connecting plate 13. A hollow column 19 is fixedly connected inside the sliding plate 15. The hollow column 19 is used to accommodate the ball clamp 18 and the third spring 17, thus providing space for the sliding of the ball clamp 18 and the extension and contraction of the spring, ensuring that the ball clamp 18 can move stably between the inner wall of the connecting plate 13 and the slot 16. The ball clamp 18 is slidably connected to the inner wall of the hollow column 19, and the ball clamp 18 cooperates with the... The groove 16 and the third spring 17 perform a positioning and locking movement. When the sliding plate 15 moves, the locking ball 18 is squeezed and compressed by the third spring 17. When it moves to the position of the groove 16, the third spring 17 pushes the locking ball 18 into the groove 16, achieving the effect of quickly locking the position of the sliding plate 15 and reducing manual adjustment time. The inner wall of the hollow column 19 is provided with a third spring 17. The third spring 17 is used to provide elastic thrust for the locking ball 18, so that when the locking ball 18 moves to the position of the groove 16, it pushes it into the groove 16 to achieve locking. At the same time, when the sliding plate 15 moves, the locking ball 18 is allowed to compress the spring and disengage from the groove 16, ensuring that the sliding plate 15 can be flexibly adjusted in position. Both ends of the third spring 17 are fixedly connected to the outer wall of the locking ball 18. The outer wall of the locking ball 18 is slidably connected to the inner wall of the groove 16 and the inner wall of the connecting plate 13.

[0037] Working principle: When clamping the workpiece, cylinder 5 drives the first trapezoidal plate 6 to move horizontally. The inclined sidewall of the first trapezoidal plate 6 contacts the inclined surface at the bottom of the second trapezoidal plate 7, converting the horizontal driving force into a lateral thrust perpendicular to the workpiece direction, pushing the second trapezoidal plate 7 to slide along the slide rail 12. At this time, the second trapezoidal plate 7 compresses the first spring 9 on the sidewall of the fixing block 8, allowing the spring to store elastic potential energy. After the workpiece is placed, cylinder 5 resets, and the first spring 9 releases its potential energy, pulling the second trapezoidal plate 7 to slide in the opposite direction, cooperating with the adaptive component to achieve clamping. In the adaptive component, when the connecting column 11 is subjected to workpiece pressure, it slides along the inner wall of the hollow block 4 and compresses the second spring 10. The elastic force of the second spring 10 compensates for minor errors in workpiece dimensions, ensuring uniform and stable clamping force and avoiding workpiece deformation caused by rigid contact.

[0038] During the positioning and limiting stage, the sliding plate 15 is pushed to drive the soft block 14 to slide along the side wall of the connecting plate 13, and the soft block 14 contacts the workpiece surface to achieve initial positioning. During the sliding process, the hollow column 19 moves with the sliding plate 15, and the retaining ball 18 inside it is squeezed and compressed by the inner wall of the connecting plate 13 to compress the third spring 17. When the retaining ball 18 moves to the position of the retaining groove 16, the third spring 17 resets and pushes the retaining ball 18 into the retaining groove 16, completing the position locking of the sliding plate 15. Through the cooperation of the retaining ball 18 with different retaining grooves 16, the limiting position of the soft block 14 can be quickly adjusted to adapt to the positioning requirements of pump covers of different specifications, reducing manual adjustment time. At the same time, the elastic contact of the soft block 14 further buffers the clamping stress and improves the positioning accuracy.
