Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to an adaptive assembly component clamping device. Background Technology

[0002] Adaptive assembly fixtures are an important type of fixture in the field of mechanical engineering. By changing or adjusting components, the fixture function can be adapted. They are widely used in various scenarios such as grinding, welding, and assembly in industrial production. They can adapt to the clamping requirements of workpieces of different sizes and shapes, and are especially suitable for production lines that need to process various styles of products with similar shapes.

[0003] However, while existing adaptive assembly fixtures can adapt to clamping various types of products, their adaptive mechanisms still have limitations in their adjustment range. When the size or shape of the products to be clamped varies significantly, the adaptive capabilities of existing fixtures often cannot fully meet the requirements for precise and reliable clamping. This means that for workpieces exceeding their preset adaptation range, existing fixtures may not be able to provide sufficient clamping force or position the workpiece in the ideal location, thus affecting assembly quality and production efficiency.

[0004] This limitation leads to the need for frequent fixture changes or time-consuming manual adjustments when handling diverse products, which becomes a bottleneck, especially in automated production lines. Current technology lacks an adaptive assembly fixture that can further refine its gripping position and force through adjustable functions, building upon its adaptive capabilities, to more effectively handle significant variations in workpiece size and shape.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0006] This utility model discloses an adaptive assembly component fixture device, which aims to solve the technical problem that existing adaptive assembly fixtures have limited adaptability when dealing with large differences in workpiece size and shape, and cannot fully meet the requirements for precise and reliable clamping. This may require frequent fixture replacement or time-consuming manual adjustments, which affects assembly quality and production efficiency.

[0007] The technical solution of this utility model is as follows:

[0008] This utility model discloses an adaptive assembly component clamping device, comprising: a mounting frame; a fixed chuck fixed on the mounting frame; a movable chuck for cooperating with the fixed chuck to clamp a workpiece; an outer tube disposed on the mounting frame; a slide rod slidably disposed within the outer tube, the slide rod moving toward the fixed chuck under the action of a first air pressure; a mounting block connected to the slide rod, the movable chuck slidably disposed on the mounting block; a latch for locking the slide rod when the slide rod drives the movable chuck to abut against the workpiece, thereby restricting the slide rod from moving away from the fixed chuck; a drive block movably disposed on the mounting block, the drive block and the movable chuck having mutually cooperating inclined surfaces; and a cylinder for driving the drive block to move after the slide rod is locked, thereby driving the movable chuck to move toward the fixed chuck through the engagement of the inclined surfaces.

[0009] This technical solution enables the movable chuck to quickly approach the workpiece and adaptively lock its position by first using pneumatically driven slide rods, and then using cylinders to drive the drive block and inclined plane to achieve precise fine-tuning and clamping of the movable chuck, thereby improving the fixture's adaptability and clamping accuracy for workpieces of different sizes.

[0010] Furthermore, the drive block is provided with a linkage rod, and the movable chuck is provided with an inclined groove that cooperates with the linkage rod; when the cylinder retracts, the drive block drives the linkage rod to slide in the inclined groove, so as to drive the movable chuck to move away from the fixed chuck.

[0011] This technical solution enables the automatic reset of the moving chuck when the cylinder contracts, improving the automation level and work efficiency of the fixture.

[0012] More specifically, in some embodiments, a compression spring is also included, disposed between the drive block and the mounting block, the compression spring being used to drive the drive block to move when the cylinder retracts.

[0013] This technical solution can assist or ensure the reliable reset of the drive block when the cylinder contracts, further improving the stability of the fixture's movement.

[0014] Preferably, the slide bar has a slot, which includes an inclined surface and a flat surface; it also includes an elastic rod, one end of which is connected to the mounting bracket and the other end of which is connected to the buckle, so as to drive the buckle to abut against the flat surface of the slot.

[0015] This technical solution enables the elastic rod to drive the buckle to reliably abut against the slot plane on the slide bar, achieving stable locking of the slide bar and ensuring the accuracy of adaptive positioning.

[0016] Furthermore, when the drive block moves under the drive of the cylinder, the drive block abuts against the mounting block to press the mounting block onto the mounting bracket.

[0017] This technical solution utilizes the movement of the drive block to generate a clamping force on the mounting block, enhancing the connection rigidity between the mounting block and the mounting frame and improving the stability of the clamping process.

[0018] Furthermore, it also includes: a drive plate connected to the output end of the cylinder; a vertical rod connected to the drive block; and a limiting block disposed between the drive plate and the vertical rod; the cylinder drives the drive plate to move, and the drive plate drives the vertical rod to move through the limiting block.

[0019] This technical solution provides a specific transmission structure for a cylinder to drive a drive block, enabling the linear motion of the cylinder to be reliably transmitted to the drive block.

[0020] Furthermore, it also includes a diverter tube, which is connected to the outer tube and is used to introduce the first air pressure into the outer tube.

[0021] This technical solution provides a specific air intake structure that introduces initial air pressure into the outer pipe to drive the slide bar, ensuring the initial drive of the slide bar.

[0022] More specifically, in some embodiments, a crossbar is also included, which is detachably connected to the mounting bracket, and the resilient rod is connected to the crossbar.

[0023] This technical solution provides an installation structure for an elastic rod, and the detachable design of the crossbar facilitates the installation and maintenance of the elastic rod.

[0024] Preferably, it also includes a rubber sleeve, which is fitted onto the end of the movable chuck facing the fixed chuck.

[0025] This technical solution utilizes a rubber sleeve to increase the friction between the moving chuck and the workpiece, thereby protecting the workpiece surface and improving clamping stability and workpiece-friendliness.

[0026] Furthermore, the mounting block is provided with a guide groove, and the movable clamp is slidably disposed in the guide groove.

[0027] This technical solution provides precise guidance for the sliding of the moving chuck on the mounting block, ensuring the stability and accuracy of the moving chuck's movement.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] 1. This utility model provides an adaptive assembly component clamping device, which achieves a two-stage clamping process by setting up a sliding rod, a buckle, a drive block, and a cylinder. First, the sliding rod is driven by a first pneumatic pressure to move the movable chuck forward rapidly until it contacts the workpiece surface. At this point, the buckle locks with the sliding rod, completing the initial adaptive positioning of the workpiece. This stage utilizes the rapid response of pneumatic pressure, allowing the clamp to quickly adapt to the approximate position of workpieces of different sizes. Subsequently, with the sliding rod locked, the cylinder drives the drive block to move. Through the inclined surface cooperation between the drive block and the movable chuck, the movable chuck is further driven towards the fixed chuck for precise fine-tuning clamping.

[0030] 2. Compared to existing technologies that have limited adaptability and difficulty in handling workpieces with large dimensions or different shapes, this invention significantly expands the adaptability range of the fixture through a two-stage design of adaptive positioning followed by precise clamping. The initial slide bar movement and locking provide a coarse adaptation to the workpiece position, while the subsequent cylinder-driven inclined plane mechanism provides controllable and precise clamping force and position adjustment capabilities. This allows the fixture to more effectively handle large changes in workpiece size and shape without frequent fixture changes or complex manual adjustments. This technical solution not only improves the fixture's compatibility with diverse products but also ensures clamping accuracy and reliability during assembly through precise secondary clamping, thereby improving production efficiency and product quality and effectively solving the problems mentioned in the background technology.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0037] The adaptive assembly component clamping device proposed in this application is mainly used for clamping products of different sizes or shapes during assembly or processing on industrial production lines. This device achieves adaptive clamping and adjustable clamping force on the workpiece by combining pneumatically driven initial positioning and mechanical locking with cylinder-driven final clamping.

[0038] Specifically, the adaptive assembly component fixture device includes a mounting bracket 1, a fixed chuck 2, a movable chuck 18, an outer tube 6, a slide bar 7, a mounting block 8, a buckle 9, a drive block 17, and a cylinder 11.

[0039] The mounting frame 1 serves as the basic support structure for the entire clamping device and can be fixed to a workbench or production line. The fixed chuck 2 is fixed to the mounting frame 1 and serves as a fixed end for clamping the workpiece. The movable chuck 18 is used to cooperate with the fixed chuck 2 to clamp the workpiece, and it is movable relative to the fixed chuck 2.

[0040] The outer tube 6 is mounted on the mounting bracket 1, providing guidance and support for the slide rod 7. The slide rod 7 is slidably disposed within the outer tube 6 and moves towards the fixed clamp 2 under the action of a first air pressure. This first air pressure can be provided by an external air source, connected to the outer tube 6 through appropriate piping, to push the slide rod 7 forward. The mounting block 8 is connected to the slide rod 7 and moves with it. The movable clamp 18 is slidably disposed on the mounting block 8, meaning that the movable clamp 18 can move relative to the mounting block 8.

[0041] The latch 9 is used to lock into the slide bar 7 when the slide bar 7 moves the chuck 18 to abut against the workpiece, thereby restricting the slide bar 7 from moving away from the fixed chuck 2. The latch 9 can be a mechanical locking mechanism, such as a spring-driven pin, pawl, or wedge. When the slide bar 7 moves to a predetermined position or encounters resistance from the workpiece, the latch 9 engages with a corresponding structure (e.g., a groove or hole) on the slide bar 7, thereby preventing the slide bar 7 from retracting.

[0042] The drive block 17 is movably mounted on the mounting block 8. A mutually engaging inclined surface is provided between the drive block 17 and the movable chuck 18. These inclined surfaces may be one or more inclined surfaces on the drive block 17 in contact with one or more inclined surfaces on the movable chuck 18. When the drive block 17 moves relative to the movable chuck 18, a force component perpendicular to the inclined surface is generated due to the action of the inclined surface, thereby pushing the movable chuck 18 toward or away from the fixed chuck 2.

[0043] Cylinder 11 is used to drive drive block 17 to move after slide bar 7 is locked in place by latch 9. Cylinder 11 can be a pneumatic linear actuator, with its output end connected to drive block 17 or connected to drive block 17 via a transmission mechanism. When cylinder 11 is activated, drive block 17 moves on mounting block 8, and through the inclined surface engagement between it and movable chuck 18, drives movable chuck 18 to move toward fixed chuck 2, thereby applying the final clamping force to the workpiece.

[0044] When using the adaptive assembly component clamping device of this application to clamp a workpiece, the workpiece is first placed between the fixed chuck 2 and the movable chuck 18. Next, a first air pressure is applied to the outer tube 6, which pushes the slide rod 7 towards the fixed chuck 2. Since the mounting block 8 is connected to the slide rod 7, and the movable chuck 18 is slidably mounted on the mounting block 8, the slide rod 7 will cause the mounting block 8 and the movable chuck 18 to move together towards the workpiece. When the movable chuck 18 contacts the workpiece surface, the movement of the slide rod 7 is hindered. At this time, the latch 9 engages with the corresponding position on the slide rod 7, fixing the slide rod 7 in place, thereby initially positioning the movable chuck 18 so that it is in close contact with the workpiece. Subsequently, the cylinder 11 is activated, driving the drive block 17 to move on the mounting block 8. Because of the interlocking inclined surfaces between the drive block 17 and the movable chuck 18, the movement of the drive block 17 transmits force to the movable chuck 18 through the inclined surfaces, driving the movable chuck 18 to move further toward the fixed chuck 2, applying a precise and adjustable clamping force to the workpiece. This two-stage clamping process—first achieving rapid adaptive positioning and locking through pneumatic pressure, and then achieving precise and powerful final clamping through cylinders and inclined surfaces—enables the fixture to effectively clamp workpieces with varying sizes or shapes. Compared to existing technologies that primarily rely on a single mechanism for positioning and clamping, this application significantly improves the fixture's adaptability, clamping reliability, and adjustability by separating the initial positioning and final clamping functions and employing different drive and locking mechanisms. For example, for the same series of products with slightly varying dimensions, the initial positioning driven by the first pneumatic pressure can quickly adapt to the actual size of the workpiece, while the locking of the latch 9 ensures the stability of the positioning. Subsequently, the controllable driving force provided by cylinder 11 is converted into clamping force on the workpiece through the inclined plane. This force can be adjusted as needed to avoid damage to the workpiece or insufficient clamping force. The entire process achieves flexible, efficient, and precise clamping of the workpiece.

[0045] In some embodiments described above in this application, a clamping scheme is proposed in which the driving block 17 is moved by the cylinder 11 to drive the movable chuck 18 to move toward the fixed chuck 2 through the engagement of the inclined surface. However, in its implementation, how to reliably release the clamp, i.e., how to drive the movable chuck 18 to move away from the fixed chuck 2, is not explained in detail. In this regard, this application further proposes an adaptive assembly component clamping device, wherein the driving block 17 is provided with a connecting rod 14, and the movable chuck 18 is provided with an inclined groove 15 that engages with the connecting rod 14; when the cylinder 11 retracts, the driving block 17 drives the connecting rod 14 to slide in the inclined groove 15, thereby driving the movable chuck 18 to move away from the fixed chuck 2.

[0046] Specifically, the linkage 14 refers to a rod-shaped structure disposed on the drive block 17, one end of which can be fixedly connected to the drive block 17. The inclined groove 15 refers to a groove with a certain inclination angle opened on the movable chuck 18. The shape and size of the inclined groove 15 are designed to cooperate with the linkage 14, so that the linkage 14 can slide within the inclined groove 15. The cooperation between the linkage 14 and the inclined groove 15 forms a mechanism that converts the linear motion of the drive block 17 into the linear motion of the movable chuck 18. The direction of motion of the movable chuck 18 relative to the direction of motion of the drive block 17 is affected by the inclination angle of the inclined groove 15.

[0047] The solution of this application, by setting a connecting rod 14 and a slanted groove 15 between the drive block 17 and the movable chuck 18, allows the cylinder 11 to not only drive the movable chuck 18 to perform a clamping action, but also to drive the movable chuck 18 to perform a releasing action through its retraction stroke. Specifically, when the cylinder 11 retracts, its output end drives the drive block 17 to move away from the fixed chuck 2. Since the connecting rod 14 is set on the drive block 17 and cooperates with the slanted groove 15 on the movable chuck 18, the movement of the drive block 17 forces the connecting rod 14 to slide within the slanted groove 15. Because the slanted groove 15 has a specific inclination angle, the sliding of the connecting rod 14 within the slanted groove 15 generates a component force perpendicular to the moving direction of the drive block 17. This component force acts on the movable chuck 18, driving the movable chuck 18 to move away from the fixed chuck 2, thereby realizing the release of the clamp. It is precisely because of the ingenious cooperation between the connecting rod 14 and the inclined groove 15 that the retraction stroke of the cylinder 11 can be effectively used to drive the chuck 18 to retract.

[0048] Through the above technical solution, this application provides a mechanism for bidirectional driving of clamping and releasing of a fixture using the same cylinder 11. Compared with the basic solution that relies solely on external force (such as a spring or manual operation) for releasing, this application actively drives the movable chuck 18 to retract through the contraction stroke of the cylinder 11, ensuring the reliability and controllability of the fixture's releasing action, avoiding incomplete releasing or jamming problems caused by external factors, and improving the working efficiency and stability of the fixture. The cooperation structure between the linkage 14 and the inclined slot 15 is simple and compact, easy to manufacture and integrate, and can effectively convert the linear motion of the drive block 17 into the retraction motion of the movable chuck 18, resulting in a compact structure and high transmission efficiency.

[0049] In some preferred embodiments, the linkage 14 can be a cylindrical pin, one end of which is fixed to the side of the drive block 17. The inclined groove 15 is an inclined straight groove opened at the corresponding position on the side of the movable chuck 18. When the cylinder 11 retracts, the drive block 17 moves backward, driving the cylindrical pin-shaped linkage 14 to move backward. Since the linkage 14 is restricted to sliding within the inclined groove 15 of the movable chuck 18, the backward movement of the linkage 14 will apply a thrust to the movable chuck 18 along the inclined direction of the inclined groove 15. This thrust is decomposed into a component force along the sliding direction of the movable chuck 18 (i.e., away from the fixed chuck 2) and a component force perpendicular to this direction. Among them, the component force along the sliding direction of the movable chuck 18 drives the movable chuck 18 to move backward, realizing the release of the clamp. The inclination angle of the inclined groove 15 can be designed and adjusted according to the required retraction distance of the movable chuck 18 and the retraction stroke of the cylinder 11.

[0050] In some embodiments described above in this application, the drive block 17 is moved by the contraction of the cylinder 11, and then the movable chuck 18 is moved away from the fixed chuck 2 by the cooperation of the inclined plane. However, in practical applications, the movement of the drive block 17 or the movable chuck 18 may be affected by factors such as friction, resulting in its return not being fast or reliable enough.

[0051] In this regard, this application further proposes that, in order to ensure that the drive block 17 and the moving chuck 18 can return to their original positions reliably and quickly, a compression spring 20 is provided between the drive block 17 and the mounting block 8.

[0052] The compression spring 20 is an elastic element capable of storing and releasing mechanical energy. It is disposed between the drive block 17 and the mounting block 8, and can be compressed and installed within this space. The compression spring 20 is used to drive the drive block 17 to move away from the fixed chuck 2 by using the elastic potential energy stored in it when the cylinder 11 contracts.

[0053] The solution of this application provides a compression spring 20 between the drive block 17 and the mounting block 8. When the cylinder 11 retracts to drive the drive block 17, the elastic force of the compression spring 20 assists or actively pushes the drive block 17 to move. It is precisely because the compression spring 20 provides additional driving force that the drive block 17 can overcome any possible frictional resistance, thereby ensuring that the drive block 17 and its linked moving chuck 18 can reliably and quickly return to their initial position.

[0054] Through the above technical solution, by adding the auxiliary driving effect of the compression spring 20, this application can effectively solve the problem of poor or unreliable return that may be caused by relying solely on the contraction of the cylinder 11, significantly improve the stability and efficiency of the return of the moving chuck 18, and thus improve the working reliability of the entire clamping device.

[0055] In some preferred embodiments, the compression spring 20 can be installed in a blind hole in the mounting block 8, with one end abutting the bottom of the blind hole and the other end abutting the corresponding surface on the drive block 17. When the cylinder 11 extends to drive the drive block 17 to move forward, the compression spring 20 is compressed; when the cylinder 11 retracts, the compressed spring 20 releases energy, pushing the drive block 17 to move backward.

[0056] In the present application, when the slide bar 7 moves the chuck 18 to abut against the workpiece, the latch 9 locks the slide bar 7 in place to restrict its movement away from the fixed chuck 2. However, in practical applications, relying solely on the locking mechanism between the latch 9 and the slide bar 7 may result in an unstable lock, especially when clamping workpieces of a certain weight. The slide bar 7 may experience slight displacement due to force, affecting the stability of the clamping. To address this, the present application proposes an improved solution: a slot is formed on the slide bar 7, comprising an inclined surface and a flat surface; an elastic rod 10 is also included, with one end connected to the mounting bracket 1 and the other end connected to the latch 9, driving the latch 9 to abut against the flat surface of the slot.

[0057] The beveled design of the slot facilitates the smooth sliding of the latch 9 into the slot during the movement of the slide bar 7; the flat design is used to abut against the latch 9, providing a stable locking force. The elastic rod 10 can be made of spring steel or other materials with good elasticity, and its function is to provide a continuous thrust to the latch 9, ensuring that it always maintains tight contact with the slot. As a preferred embodiment, the elastic rod 10 can be set to be adjustable, for example, by adjusting the preload of the elastic rod 10 through a threaded connection, thereby adapting to the clamping requirements of different workpieces.

[0058] In this application, when the slide bar 7 moves the chuck 18 to contact the workpiece, the latch 9 automatically engages with the slot on the slide bar 7 under the action of the elastic rod 10. Because the slot has both an inclined surface and a flat surface, the latch 9, guided by the inclined surface, smoothly enters the slot and ultimately abuts against the flat surface, thus reliably locking the slide bar 7. Even if the slide bar 7 is subjected to a certain external force during clamping, the elastic rod 10 ensures close contact between the latch 9 and the slot surface, effectively preventing displacement of the slide bar 7 and ensuring clamping stability.

[0059] The above technical solutions effectively improve the locking reliability and clamping stability of the clamping device. Even when clamping workpieces of a certain weight, the slide bar 7 will not shift, thereby improving assembly accuracy and efficiency. Furthermore, the design of the elastic rod 10 allows the latch 9 to automatically engage with the slot without manual operation, further enhancing the automation level of the clamping device.

[0060] In the adaptive assembly component fixture device of this application, although the drive block 17 can be moved by the cylinder 11, and then the movable chuck 18 can be moved towards the fixed chuck 2 through the engagement of the inclined plane to achieve workpiece clamping, during the clamping process, the mounting block 8 may experience slight deformation or vibration due to uneven force or insufficient structural strength. This will affect the clamping accuracy and stability of the fixture, and thus affect the assembly quality. In response, this application proposes an optimization scheme: when the drive block 17 moves under the drive of the cylinder 11, the drive block 17 abuts against the mounting block 8 to press the mounting block 8 onto the mounting frame 1, thereby improving the overall rigidity and stability of the fixture.

[0061] The movement of the drive block 17 under the drive of the cylinder 11 means that the output end of the cylinder 11 pushes the drive block 17, causing it to move. The drive block 17 abutting against the mounting block 8 means that after the drive block 17 moves to a certain position, its surface contacts the surface of the mounting block 8. The mounting block 8 pressing against the mounting frame 1 means that the pressure applied by the drive block 17 makes the mounting block 8 fit tightly against the mounting frame 1, thereby reducing or eliminating the gap between the mounting block 8 and the mounting frame 1 and improving the rigidity of the connection.

[0062] Specifically, when cylinder 11 operates, its output end pushes drive block 17 to move. During this movement, drive block 17 gradually contacts and applies pressure to mounting block 8. As cylinder 11 continues to push, the pressure of drive block 17 on mounting block 8 gradually increases until mounting block 8 is firmly pressed onto mounting bracket 1. In this way, deformation and vibration of mounting block 8 can be effectively suppressed, improving the clamping accuracy and stability of the fixture.

[0063] The solution proposed in this application effectively improves the overall rigidity and stability of the fixture by using the drive block 17 to press the mounting block 8 during the clamping process. This is because when the drive block 17 abuts against the mounting block 8, it is equivalent to adding an additional support point between the mounting block 8 and the mounting frame 1, thereby dispersing the clamping force and reducing the stress concentration on the mounting block 8. Furthermore, the pressing action of the drive block 17 can effectively suppress minor deformations and vibrations of the mounting block 8, thus improving the clamping accuracy and stability of the fixture.

[0064] The above technical solution can effectively improve the clamping accuracy and stability of the fixture, thereby ensuring assembly quality. Compared with the prior art, the solution of this application does not require the addition of additional structural components; it can be achieved simply by optimizing the structure and motion trajectory of the drive block 17. Therefore, it has the advantages of low cost and ease of implementation.

[0065] In the above embodiments of this application, although the drive block 17 can be moved by the cylinder 11, and then the moving chuck 18 can be moved toward the fixed chuck 2 by the cooperation of the inclined plane, the connection between the drive block 17 and the cylinder 11 is relatively simple, which may result in low driving efficiency or unstable connection.

[0066] To address this, this application provides an improved solution in which the adaptive assembly component fixture device further includes a drive plate 12, a vertical rod 21, and a limiting block 13. The drive plate 12 is connected to the output end of the cylinder 11; the vertical rod 21 is connected to the drive block 17; the limiting block 13 is disposed between the drive plate 12 and the vertical rod 21; the cylinder 11 drives the drive plate 12 to move, and the drive plate 12 drives the vertical rod 21 to move via the limiting block 13.

[0067] Specifically, the drive plate 12 transmits the driving force of the cylinder 11, the vertical rod 21 transmits the driving force to the drive block 17, and the limiting block 13 ensures that the drive plate 12 can effectively drive the vertical rod 21 to move. As a preferred embodiment, the limiting block 13 can be made of an elastic material, such as rubber or elastic plastic, which can reduce impact and vibration, and improve the stability and service life of the device.

[0068] In this application, cylinder 11 drives drive plate 12 to move, drive plate 12 drives vertical rod 21 to move via limit block 13, and vertical rod 21 then drives drive block 17 to move, thereby driving the movable chuck 18. Due to the presence of limit block 13, the connection between drive plate 12 and vertical rod 21 is more reliable, effectively avoiding losses during the transmission of driving force and improving driving efficiency. Furthermore, by adopting the combined structure of drive plate 12, vertical rod 21, and limit block 13, the driving force of cylinder 11 can be dispersed, reducing direct impact on drive block 17, thereby improving the stability and service life of the device.

[0069] The above technical solutions can improve driving efficiency and connection stability, thereby enhancing the overall performance of the adaptive assembly component fixture device.

[0070] In the adaptive assembly component clamping device of this application, although the sliding rod 7 can be driven by the first air pressure to move the movable chuck 18 to achieve contact with the workpiece, if the first air pressure is unstable, it will affect the movement of the movable chuck 18, resulting in unstable clamping effect. To address this, this application proposes an improvement solution, namely, adding a diversion pipe 5, which is connected to the outer pipe 6, to introduce the first air pressure into the outer pipe 6, thereby ensuring stable air pressure.

[0071] The diversion pipe 5 refers to the pipe used to divert airflow. It can be made of materials such as metal or plastic, and its specific shape and size can be designed according to actual needs. As a preferred embodiment, the diversion pipe 5 can adopt a Y-shaped structure, with one port connected to the air source and the other two ports connected to two outer pipes 6 respectively, thereby realizing the simultaneous introduction of the first air pressure into the two outer pipes 6.

[0072] Specifically, when the initial air pressure supplied by the air source passes through the distributor pipe 5, the distributor pipe 5 can evenly distribute the air pressure to each outer pipe 6, ensuring that the air pressure in each outer pipe 6 is stable. As a result, when the slide bar 7 moves within the outer pipe 6, it can obtain a stable driving force, thereby ensuring that the moving chuck 18 can accurately contact the workpiece and improve the stability of the clamping.

[0073] By using the above technical solution to divert air pressure through the diversion pipe 5, the problem of poor clamping effect caused by unstable air pressure can be effectively avoided, thereby improving the reliability and stability of the adaptive assembly component fixture device.

[0074] In the present application, one end of the elastic rod 10 is connected to the mounting bracket 1. Although this enables the snap-lock 9 to be reset, in practical applications, the structure of the mounting bracket 1 is complex and inconvenient for the installation and fixation of the elastic rod 10. Therefore, the present application proposes an improved solution, in which the elastic rod 10 is detachably connected to the mounting bracket 1 via the crossbar 19, thereby facilitating the installation and fixation of the elastic rod 10.

[0075] The crossbar 19 is a rod-shaped structure that can be detachably connected to the mounting bracket 1 by bolts, welding, or other means, facilitating the disassembly and replacement of the crossbar 19. The elastic rod 10 can be an elastic element such as a spring or elastic sheet, with one end fixed to the crossbar 19 and the other end connected to the buckle 9, providing a restoring force for the buckle 9.

[0076] In this application, by setting a crossbar 19 and connecting the elastic rod 10 to it, the installation position of the elastic rod 10 becomes more flexible and adjustable. This allows for easy adjustment of the position and angle of the elastic rod 10 according to actual needs, ensuring that the latch 9 can accurately and reliably engage with the slot on the slide bar 7. This avoids the problem of the latch 9 malfunctioning due to improper installation of the elastic rod 10. Furthermore, by detachably connecting the crossbar 19 to the mounting bracket 1, the replacement and maintenance of the crossbar 19 become more convenient and faster, reducing maintenance costs.

[0077] The above technical solution makes the installation position of the elastic rod 10 more flexible and adjustable, allowing for easy adjustment of its position and angle according to actual needs. This ensures that the buckle 9 can accurately and reliably engage with the slot on the slide bar 7, avoiding the problem of the buckle 9 malfunctioning due to improper installation of the elastic rod 10. Furthermore, by detachably connecting the crossbar 19 to the mounting bracket 1, the replacement and maintenance of the crossbar 19 become more convenient and faster, reducing maintenance costs.

[0078] In some embodiments of the adaptive assembly component clamping device of this application, the movable chuck 18 is in direct contact with the workpiece. During frequent use, this may cause wear or damage to the workpiece surface, which is unacceptable, especially for workpieces with high surface finish requirements. Therefore, this application proposes an improvement: a rubber sleeve 16 is fitted onto the end of the movable chuck 18 facing the fixed chuck 2. Through the buffering effect of the rubber sleeve 16, direct friction and collision between the movable chuck 18 and the workpiece are reduced or even avoided.

[0079] The rubber sleeve 16 is a sleeve-like structure made of an elastic material, whose main function is to provide cushioning and protection. Specifically, the rubber sleeve 16 can be made of natural rubber, synthetic rubber, or other materials with similar elasticity and wear resistance. The shape and size of the rubber sleeve 16 should match the end of the movable chuck 18 to ensure a tight fit and prevent it from falling off during use. As a preferred embodiment, the inner surface of the rubber sleeve 16 can be provided with anti-slip texture to increase the friction between it and the movable chuck 18, further ensuring its stability.

[0080] The solution of this application effectively absorbs the impact and vibration generated during clamping by adding a rubber sleeve 16 as a buffer layer between the moving chuck 18 and the workpiece, thereby preventing the moving chuck 18 from directly contacting the workpiece surface. Because rubber has good elasticity, the rubber sleeve 16 can adapt to workpieces of different shapes and sizes, providing a gentler clamping force and reducing the risk of workpiece deformation or damage caused by uneven or excessive clamping force.

[0081] Through the above technical solution, this application can effectively protect the workpiece surface and improve assembly quality and efficiency. Especially when handling fragile or valuable workpieces, the rubber sleeve 16 can significantly reduce damage caused by the fixture, thereby reducing scrap rate and production costs. In addition, the easy replaceability of the rubber sleeve 16 also allows the fixture to adapt to workpieces of different types and materials, improving the versatility and flexibility of the fixture.

[0082] In the above-described solution of this application, the movable chuck 18 is directly connected to the mounting block 8. During the workpiece clamping process, the movable chuck 18 may shift due to uneven force, affecting the stability and accuracy of clamping. To address this, this application proposes an improved solution: the mounting block 8 is provided with a guide groove, and the movable chuck 18 is slidably disposed within the guide groove. The guide groove constrains the movement trajectory of the movable chuck 18, thereby improving the stability and accuracy of clamping.

[0083] The guide groove refers to a recessed structure formed on the mounting block 8 to guide the movement of the movable chuck 18. The shape of the guide groove can be designed according to actual needs, such as a straight line, an arc, or other shapes, as long as it ensures that the movable chuck 18 does not deviate during movement. The movable chuck 18 is slidably disposed within the guide groove, which can be achieved through sliding fit, rolling fit, or other fitting methods. As a preferred embodiment, the inner wall of the guide groove can be polished to reduce the friction of the movable chuck 18 during movement and improve the smoothness of the movement.

[0084] The solution of this application achieves effective constraint on the movement trajectory of the movable chuck 18 by opening a guide groove on the mounting block 8 and sliding the movable chuck 18 in the guide groove, thereby preventing the movable chuck 18 from deviating during the workpiece clamping process and ensuring the stability and accuracy of clamping.

[0085] The above technical solutions can effectively improve the clamping accuracy and stability of the fixture device, ensure the accurate positioning of the workpiece during the assembly process, and thus improve the assembly quality and efficiency.

[0086] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
