Description

Technical Field

[0001] This utility model relates to the field of automotive clutch housing processing technology, and in particular to a hydraulic clamping fixture for automotive clutch housings. Background Technology

[0002] Chinese document CN213592342U discloses an automotive clutch housing positioning fixture, comprising a base plate and multiple positioning units. The base plate is fixed to a worktable. Each positioning unit includes a pressure block, a pressure cap, a positioning reference block, and a thin cylinder. The positioning reference block is mounted on the base plate and is annular. A pressure block is positioned above the positioning reference block, and a pressure cap is mounted on the pressure block. A thin cylinder is positioned inside the positioning reference block and fixed to the base plate. The protruding end of the pressure cap extends from the center of the pressure block into the variable-diameter positioning pin of the thin cylinder. This invention improves the stability of automotive clutch housing positioning, simplifies and speeds up clamping, and ensures reliable repositioning during adjustment or replacement, thereby saving manpower and increasing productivity.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use: The uneven clamping force transmission of this device can easily lead to deformation of the clutch housing. It achieves clamping through multiple independent positioning units and pressure blocks. The forces of each positioning unit are difficult to keep synchronized, resulting in localized force concentration on the housing, which in turn causes slight deformation and affects the machining accuracy.

[0004] In summary, this application proposes a hydraulic clamping fixture for automotive clutch housings to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic clamping fixture for automotive clutch housing, which can solve the problem of uneven clamping force transmission, which easily leads to deformation of the clutch housing. It achieves clamping through multiple independent positioning units and pressure blocks. However, it is difficult to keep the force of each positioning unit synchronized, which causes local force concentration on the housing and thus produces slight deformation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic clamping fixture for an automotive clutch housing, comprising: The box body has a rotating cover on the top. A clamping assembly is mounted on a rotating cover plate. The clamping assembly includes a square base, a connecting rod, a sliding block, a first connecting plate, a second connecting plate, a hydraulic rod, a slide groove, and a clamping seat. A slide groove is provided on the top of the rotating cover plate, and a sliding block is slidably installed inside the slide groove. One end of the connecting rod is hinged to the bottom of the square base, and the other end of the connecting rod is hinged to the bottom of the sliding block. The bottom of the two sets of sliding blocks is fixedly mounted with the first connecting plate and the second connecting plate. One end of the hydraulic rod is fixedly mounted with one side of the first connecting plate, and the free end of the hydraulic rod is fixedly mounted with one side of the second connecting plate. A clamping seat is fixedly mounted on the top of the sliding block.

[0007] Preferably, the connecting rods are arranged in four sets in a circular array. The linkage structure between the components ensures that the clamping force is evenly transmitted to the clutch housing, avoiding housing deformation caused by uneven local force. Combined with the V-shaped anti-slip groove and anti-slip texture of the clamping seat, the clamping stability is greatly improved, effectively preventing displacement or vibration of the housing during processing and ensuring processing accuracy. At the same time, the entire clamping action is driven by a hydraulic rod, eliminating the need for manual adjustment. Only the hydraulic system needs to be controlled to quickly clamp and release the housing, simplifying the operation process and reducing manual labor intensity.

[0008] Preferably, the clamping seat is stepped, and the clamping seat is provided with anti-slip grooves. The anti-slip grooves are V-shaped and have anti-slip textures inside. The stepped structure can be adapted to clutch housings of different specifications, expanding the applicability of the clamp. The anti-slip grooves can increase the friction between the clamping seat and the housing, prevent the housing from sliding during processing, and ensure processing stability.

[0009] Preferably, a motor is fixedly installed on the inner bottom of the housing, and a rotating column is fixedly installed on the output shaft of the motor. The top of the rotating column passes through the square base and is fixedly installed on the bottom of the rotating cover. The motor directly drives the rotating cover to rotate through the rotating column, eliminating the need for an additional transmission mechanism, reducing energy loss, and enabling flexible adjustment of the housing processing angle to meet multi-directional processing needs.

[0010] Preferably, the square base is rotatably mounted on the rotating column. The rotational cooperation between the square base and the rotating column can prevent the rotating cover from driving other fixed components to move together, ensuring the stability of the clamping assembly, reducing wear between components, and extending the service life of the clamp.

[0011] Preferably, the distance from the hinge point of the four sets of connecting rods to the square base and the sliding block to the center of the square base is equal. The four sets of connecting rods are equidistantly distributed, which can evenly transmit the force to each sliding block, ensuring that the clamping seat moves towards the center synchronously and smoothly, avoiding the clutch housing from undergoing slight deformation due to uneven force, and further improving the clamping accuracy and consistency.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This hydraulic clamping fixture for automotive clutch housings utilizes a square base, connecting rods, sliding blocks, connecting plate one, connecting plate two, hydraulic rods, sliding grooves, and clamping seats. The interconnected structure of these components ensures that clamping force is evenly distributed around the clutch housing, preventing deformation caused by uneven localized stress. The V-shaped anti-slip grooves and textured surfaces of the clamping seats significantly improve clamping stability, effectively preventing displacement or vibration of the housing during processing and ensuring machining accuracy. Furthermore, the entire clamping action is driven by the hydraulic rods, eliminating the need for manual adjustment. Simply controlling the hydraulic system allows for rapid clamping and releasing of the housing, simplifying the operation and reducing manual labor intensity. Attached Figure Description

[0015] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Please see Figure 1-4This utility model provides a technical solution: a hydraulic clamping fixture for an automotive clutch housing, comprising a housing 1 and a clamping assembly. The top of the housing 1 is provided with a rotating cover plate 2. The clamping assembly is disposed on the rotating cover plate 2 and includes a square base 3, a connecting rod 4, a sliding block 5, a first connecting plate 6, a second connecting plate 7, a hydraulic rod 8, a slide groove 9, and a clamping seat 10. The top of the rotating cover plate 2 is provided with a slide groove 9, and the sliding block 5 is slidably installed inside the slide groove 9. One end of the connecting rod 4 is hinged to the bottom of the square base 3, and the other end of the connecting rod 4 is hinged to the bottom of the sliding block 5. The bottom of the two sets of sliding blocks 5 is fixedly installed with the first connecting plate 6 and the second connecting plate 7. One end of the hydraulic rod 8 is fixedly installed with one side of the first connecting plate 6, and the free end of the hydraulic rod 8 is fixedly installed with one side of the second connecting plate 7. The top of the sliding block 5 is fixedly installed with the clamping seat 10.

[0017] Furthermore, the connecting rods 4 are arranged in four sets in a circular array. The clutch housing is placed between the four sets of clamping seats 10, with the bottom of the housing in contact with the surface of the rotating cover plate 2. Initial radial positioning is achieved by means of the stepped structure of the clamping seats 10. After the hydraulic system is started, the hydraulic rod 8 extends and pushes the connecting plate 6 and the connecting plate 7 to expand outward. The two sets of connecting plates drive the corresponding sliding blocks to slide outward along the sliding groove. The sliding blocks 5 transmit the force through the connecting rods 4, so that the four sets of clamping seats 10 move towards the center synchronously until the clamping seats 10 are tightly in contact with the outer wall of the clutch housing. The linkage structure between the components can ensure that the clamping force is evenly transmitted to the circumference of the clutch housing, avoiding housing deformation caused by uneven local force. With the V-shaped anti-slip groove and anti-slip texture of the clamping seats, the clamping stability is greatly improved, effectively preventing the housing from shifting or vibrating during processing, ensuring processing accuracy. At the same time, the entire clamping action is achieved by hydraulic rod drive, without the need for manual adjustment. Only the hydraulic system needs to be controlled to complete the rapid clamping and releasing of the housing, simplifying the operation process and reducing the intensity of manual labor.

[0018] Furthermore, the clamping seat 10 is stepped, and an anti-slip groove 11 is provided on the clamping seat 10. The anti-slip groove 11 has a V-shaped structure and anti-slip texture is provided in the groove. The stepped structure can be adapted to clutch housings of different specifications, expanding the application range of the clamp. The anti-slip groove can increase the friction between the clamping seat and the housing, prevent the housing from sliding during processing, and ensure processing stability.

[0019] Furthermore, a motor 12 is fixedly installed on the bottom inner side of the housing 1, and a rotating column 13 is fixedly installed on the output shaft of the motor 12. The top of the rotating column 13 passes through the square base 3 and is fixedly installed on the bottom of the rotating cover 2. The motor 12 directly drives the rotating cover 2 to rotate through the rotating column 13, without the need for an additional transmission mechanism, reducing energy loss, and at the same time realizing flexible adjustment of the housing processing angle to meet multi-directional processing needs.

[0020] Furthermore, the square base 3 is rotatably mounted on the rotating column 13. The rotational cooperation between the square base and the rotating column can prevent the rotating cover from driving other fixed parts to move together, ensuring the stability of the clamping assembly, while reducing wear between parts and extending the service life of the clamp.

[0021] Secondly, the distance from the hinge point of the four sets of connecting rods 4 to the center of the square base 3 and the sliding block 5 is equal. The four sets of connecting rods are equidistantly distributed, which can evenly transmit the force to each sliding block, ensuring that the clamping seat moves towards the center synchronously and smoothly, avoiding the clutch housing from undergoing slight deformation due to uneven force, and further improving the clamping accuracy and consistency.

[0022] Working principle: Before the device is started, the hydraulic rod 8 is in a retracted state, which drives the connecting plate 6 and the connecting plate 7 to move closer to the center. The sliding block 5 moves inward synchronously in the slide groove 9, so that the four sets of clamping seats 10 are in an open state, leaving space for the clutch housing. The clutch housing is placed between the four sets of clamping seats 10, with the bottom of the housing in contact with the surface of the rotating cover plate 2. The stepped structure of the clamping seats 10 is used to achieve initial radial positioning. After the hydraulic system is started, the hydraulic rod 8 extends and pushes the connecting plate 6 and the connecting plate 7 to expand outward. The two sets of connecting plates drive the corresponding sliding blocks to slide outward along the slide groove. The sliding block 5 transmits force through the connecting rod 4, so that the four sets of clamping seats 10 move closer to the center synchronously until the clamping seats 10 are tightly in contact with the outer wall of the clutch housing. If the housing angle needs to be adjusted during the processing, the bottom motor 12 is started. The output shaft of the motor 12 drives the rotating column 13 to rotate, which in turn drives the rotating cover plate 2 and the clamped clutch housing to rotate together.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
