Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to a clamping fixture for processing automotive parts. Background Technology

[0002] Existing technologies for clamping fixtures in automotive parts processing generally have some shortcomings, especially in ensuring the stability and uniformity of clamping when clamping parts of different shapes. Many traditional fixture designs are often customized for parts of a specific shape, which affects clamping accuracy and efficiency when dealing with parts of different shapes and sizes.

[0003] Specifically, when clamping parts of different shapes, existing clamping fixtures mostly rely on static design, which cannot be dynamically adjusted according to the specific shape of the workpiece, resulting in uneven clamping force. For example, poor contact between the clamping plate and the workpiece or excessive clamping can easily lead to deformation, damage, or insecure fixing of the parts, thus affecting machining accuracy and efficiency. In the machining of some more complex parts, it may even be necessary to change multiple fixtures, wasting a significant amount of production time and labor costs.

[0004] Furthermore, the installation and disassembly of modular panels present certain operational inconveniences. In some designs, the fixing methods for modular panels are quite complex, requiring multiple manual adjustments and even the use of specialized tools for disassembly and installation. Each time a part is replaced, manual repositioning and adjustment are necessary, which not only reduces work efficiency but also increases the risk of operational errors. For mass production, this inefficient operating method limits the overall capacity of the production line. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a clamping fixture for processing automotive parts, so as to solve the technical problems mentioned in the background art, such as the difficulty in clamping parts of different shapes and the inconvenience of installing and disassembling different part module plates.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for processing automotive parts, comprising a main frame, a rotary clamping mechanism, a template clamping mechanism, and a clamping auxiliary mechanism. The rotary clamping mechanism includes a push-pull block and a pressure block. A support is installed at the top end of the main frame, and a pressure block is rotatably installed on the support. A first rotating block is rotatably connected to the push-pull block and is rotatably connected to the top end of the main frame. A second rotating block is rotatably connected to one end of the pressure block, and the connection between the first rotating block and the push-pull block is rotatably connected to the second rotating block. The template clamping mechanism includes a clamping tube and a clamping rod. A clamping groove is provided on the outer wall of the clamping rod. An embedded spring rod is slidably provided laterally on the side wall of the clamping tube, and the embedded spring rod can extend into the clamping groove. A rotating sleeve is rotatably installed on the upper limit of the outer wall of the clamping tube, and a rotary push ball is installed on the inner wall of the rotating sleeve. The rotary push ball pushes one end of the spring rod, causing the embedded spring rod to move away from the clamping groove.

[0009] The present invention is further configured such that the snap-fit ​​auxiliary mechanism includes a positioning plate and a threaded ring. The threaded ring is threadedly connected to the outer wall of the snap-fit ​​tube. The positioning plate is installed at the bottom end of the rotating sleeve. A positioning spring is installed on the outer wall of the snap-fit ​​tube, and multiple sets of positioning springs and positioning plates are provided. Different positioning springs are embedded into different positioning plates in stages to make the rotating sleeve rotate stably. A rotary push plate is installed at the bottom end of the threaded ring. A clamping ring is slidably installed on the outer wall of the snap-fit ​​tube. A push plate is installed at the top end of the clamping ring. The rotation of the rotary push plate causes the push plate and the clamping ring to move longitudinally, so that the clamping ring fixes the rotating sleeve to the outer wall of the snap-fit ​​tube.

[0010] The present invention is further configured such that a support frame is installed at the top end of the main frame, and a module plate is installed on the support frame, and the pressure block can press against the parts of the module plate. After the module plate is installed on the support frame, it can serve as a support reference surface for the workpiece and form a clamping space with the pressure block.

[0011] The present invention is further configured such that mounting plates are installed on both sides of the support frame, and side plates are installed on both sides of the module plate, and the mounting plates and side plates are connected by the template snap-fit ​​mechanism.

[0012] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the clamping tube, and the connecting plate is fixedly installed on the side plate. The mounting plate and the side plate are connected by a template clamping mechanism, which can quickly adjust the module plate structure to adapt to different workpiece shapes and sizes.

[0013] The present invention is further configured such that a limiting block is installed at one end of the snap-fit ​​rod, and one end of the snap-fit ​​rod can pass through the side plate and the mounting plate to engage with the snap-fit ​​tube for snap-fit ​​installation.

[0014] The present invention is further configured such that a foot plate is installed at the bottom end of the main frame. The main frame serves as the skeleton of the entire tooling, bearing and supporting the installation and operation of each mechanism, providing stable structural support, and enhancing the overall rigidity and durability of the equipment.

[0015] The present invention is further configured such that a hydraulic cylinder is rotatably mounted on the foot plate, and one end of the hydraulic cylinder is rotatably connected to the push-pull block. The hydraulic cylinder drives the push-pull block to move and controls the action of the pressure block, thereby realizing automated control and improving the efficiency of the clamping process.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a clamping fixture for processing automotive parts, which has the following advantages:

[0018] This invention features a rotary clamping mechanism that, through push-pull blocks, pressure blocks, and a series of rotating connecting parts, provides a more uniform and precise clamping force. The coordinated operation of the pressure blocks and push-pull blocks ensures that the workpiece remains in a stable clamping state during processing, avoiding the problems of uneven clamping and insecure clamping that exist in traditional tooling when clamping parts of different shapes. In addition, the introduction of the rotary mechanism makes the application of clamping force more flexible and can adapt to workpieces of different sizes and shapes.

[0019] This utility model features a template snap-fit ​​mechanism, making installation and disassembly simpler and faster. Through the ingenious cooperation of the snap-fit ​​tube and snap-fit ​​rod, it can quickly switch and adjust between different modules, significantly reducing operation time and labor costs. In particular, the embedded spring rod and rotary push ball structure on the outer wall of the snap-fit ​​tube can ensure stability during snap-fit, and the movement of the rotating sleeve can effectively control the spring rod, thereby optimizing the snap-fit ​​effect and ensuring that the parts are firmly fixed.

[0020] This utility model is equipped with a snap-fit ​​auxiliary mechanism. Through the precise design of components such as the positioning plate, threaded ring, and positioning spring, the stability and flexibility of the tooling are further enhanced. The multi-level nesting design of the positioning spring and positioning plate makes the rotation process of the rotating sleeve more stable, avoiding the offset problem caused by the unstable snap-fit ​​in traditional tooling. At the same time, through the linkage of the rotary push plate and the push plate, the position of the clamping ring can be precisely controlled, ensuring the efficiency and accuracy of the snap-fit ​​process.

[0030] Please see Figures 1-5A clamping fixture for processing automotive parts includes a main frame 1, a rotary clamping mechanism, a template clamping mechanism, and a clamping auxiliary mechanism. The rotary clamping mechanism includes a push-pull block 2 and a pressure block 3. A support 4 is installed at the top end of the main frame 1, and a pressure block 3 is rotatably installed on the support 4. A first rotating block 5 is rotatably connected to the push-pull block 2 and is rotatably connected to the top end of the main frame 1. A second rotating block 101 is rotatably connected to one end of the pressure block 3. The connection between the first rotating block 5 and the push-pull block 2 is rotatably connected to the second rotating block 101. The template clamping mechanism includes a clamping tube 6 and a clamping rod 7. A clamping groove 8 is provided on the outer wall of the clamping rod 7. An embedded spring rod 9 is slidably provided on the side wall of the clamping tube 6 and can extend into the clamping groove 8. A rotating sleeve 10 is rotatably installed on the upper limit of the outer wall of the clamping tube 6, and a rotary push ball 11 is installed on the inner wall of the rotating sleeve 10. The rotary push ball 11 pushes one end of the spring rod, causing the spring rod to move away from the clamping groove 8.

[0031] In this embodiment, the part is clamped by the coordinated work of the push-pull block 2 and the pressure block 3. First, the hydraulic cylinder 24 on the foot plate 25 drives the push-pull block 2 to move. The push-pull block 2 is rotatably connected to the first rotating block 5, which is in turn rotatably connected to the top of the main frame 1. When the push-pull block 2 moves, the first rotating block 5 drives the second rotating block 101 connected to the pressure block 3 to rotate, forming a lever effect. This causes the pressure block 3 to rotate downwards and finally press against the module plate 19 on the support frame 18, firmly clamping the part to be processed. This achieves the transmission of force and the conversion of direction, making the clamping process more stable and powerful, and realizing the module clamping. The quick installation and removal of the plate 19 is suitable for different types of parts. During operation, the locking rod 7 passes through the mounting plate 20 and is inserted into the locking tube 6. The embedded spring rod 9 on the side wall of the locking tube 6 can extend into the slot 8 on the outer wall of the locking rod 7 in its natural state to achieve initial locking. The inner wall of the rotating sleeve 10 on the outer wall of the locking tube 6 is equipped with a rotary push ball 11. When the rotating sleeve 10 is in a specific position, the rotary push ball 11 pushes the embedded spring rod 9 away from the slot 8. At this time, the locking rod 7 can be inserted or removed. Rotate the rotating sleeve 10 to another position, the rotary push ball 11 moves away, and the embedded spring rod 9 springs into the slot 8 to complete the locking.

[0032] The snap-fit ​​auxiliary mechanism includes a positioning plate 12 and a threaded ring 13. The threaded ring 13 is threadedly connected to the outer wall of the snap-fit ​​tube 6. The positioning plate 12 is installed at the bottom end of the rotating sleeve 10. A positioning spring 14 is installed on the outer wall of the snap-fit ​​tube 6, and multiple sets of positioning springs 14 and positioning plates 12 are provided. Different positioning springs 14 are embedded into different positioning plates 12 in stages to make the rotating sleeve 10 rotate stably. A rotary push plate 15 is installed at the bottom end of the threaded ring 13. A clamping ring 16 is directionally slidably installed on the outer wall of the snap-fit ​​tube 6. A push plate 17 is installed at the top end of the clamping ring 16. The rotation of the rotary push plate 15 causes the push plate 17 and the clamping ring 16 to move longitudinally, so that the clamping ring 16 fixes the rotating sleeve 10 to the outer wall of the snap-fit ​​tube 6.

[0033] In this embodiment, the rotating sleeve 10 is provided with stable rotation and final fixation functions. A positioning plate 12 is installed at the bottom of the rotating sleeve 10, which cooperates with the positioning spring 14 on the outer wall of the clamping tube 6. Different positioning springs 14 are embedded into different positioning plates 12 in stages to ensure stable rotation of the rotating sleeve 10. The threaded ring 13 is threadedly connected to the outer wall of the clamping tube 6. The push plate 15 at its bottom contacts the push plate 17 at the top of the clamping ring 16. When the threaded ring 13 is rotated, the push plate 15 pushes the push plate 17, causing the clamping ring 16 to move longitudinally, and finally the rotating sleeve 10 is firmly fixed to the outer wall of the clamping tube 6 to prevent loosening during the processing.

[0034] Please see Figures 1-5 As a supplementary embodiment of a clamping fixture for processing automotive parts, which includes a rotary pressing mechanism, a template clamping mechanism, and a clamping auxiliary mechanism: A support frame 18 is installed at the top end of the main frame 1, and a module plate 19 is installed on the support frame 18. The pressure block 3 can press against the parts on the module plate 19. Mounting plates 20 are installed on both sides of the support frame 18, and side plates 21 are installed on both sides of the module plate 19. The mounting plates 20 and side plates 21 are connected by the template clamping mechanism. A connecting plate 22 is installed at the bottom end of the side wall of the clamping tube 6, and the connecting plate 22 is fixedly installed on the side plate 21. A limiting block 23 is installed at one end of the clamping rod 7, and one end of the clamping rod 7 can pass through the side plate 21 and the mounting plate 20 to engage with the clamping tube 6. A foot plate 25 is installed at the bottom end of the main frame 1, and a hydraulic cylinder 24 is rotatably installed on the foot plate 25. One end of the hydraulic cylinder 24 is rotatably connected to the push-pull block 2.

[0035] More specifically, the parts to be processed are placed on the module plate 19 on the support frame 18 at the top of the main frame 1. The side plates 21 on both sides of the module plate 19 are connected to the mounting plates 20 on both sides of the support frame 18 through the template snap-fit ​​mechanism. Specifically, the snap-fit ​​rod 7 is inserted through the mounting plate 20 into the snap-fit ​​tube 6 fixed on the side plate 21. The rotating sleeve 10 on the outer wall of the snap-fit ​​tube 6 is rotated, so that the embedded spring rod 9 springs into the snap-fit ​​groove 8 of the snap-fit ​​rod 7, achieving initial locking. The threaded ring 13 is rotated, and the pressing ring 16 is pushed by the rotary push plate 15 to rotate the threaded ring 13. The sleeve 10 is firmly fixed to the outer wall of the clamping tube 6 to ensure a stable connection of the module plate 19. The hydraulic cylinder 24 is activated to drive the push-pull block 2 to move. Through the rotational connection of the first rotating block 5 and the second rotating block 101, the pressure block 3 rotates downward and presses against the part on the module plate 19, clamping it firmly. After the part is fixed, various processing operations can be performed. After processing is completed, the hydraulic cylinder 24 moves in the opposite direction to release the pressure, and the pressure block 3 is lifted. Rotating the sleeve 10 causes the embedded spring rod 9 to exit the clamping slot 8, making the module plate 19 detachable and the processed part removed.

[0036] In summary, when the overall equipment is in use or operation: when the rotating clamping mechanism is running, the parts are clamped by the coordinated work of the push-pull block 2 and the pressure block 3. First, the hydraulic cylinder 24 on the foot plate 25 drives the push-pull block 2 to move. The push-pull block 2 is rotatably connected to the first rotating block 5, which is in turn rotatably connected to the top of the main frame 1. When the push-pull block 2 moves, the first rotating block 5 drives the second rotating block 101 connected to the pressure block 3 to rotate, forming a lever effect, causing the pressure block 3 to rotate downwards and finally press against the module plate 19 on the support frame 18, firmly clamping the parts to be processed. This realizes the transmission of force and the conversion of direction, making the clamping process more stable and powerful.

[0037] When the template snap-fit ​​mechanism is in operation, it enables the quick installation and removal of the module plate 19, applicable to different types of parts. During operation, the snap-fit ​​rod 7 passes through the mounting plate 20 and is inserted into the snap-fit ​​tube 6. The embedded spring rod 9 on the side wall of the snap-fit ​​tube 6 can extend into the slot 8 on the outer wall of the snap-fit ​​rod 7 in its natural state, achieving initial locking. The inner wall of the rotating sleeve 10 on the outer wall of the snap-fit ​​tube 6 is equipped with a rotary push ball 11. When the rotating sleeve 10 is in a specific position, the rotary push ball 11 pushes the embedded spring rod 9 away from the slot 8. At this time, the snap-fit ​​rod 7 can be inserted or removed. Rotating the rotating sleeve 10 to another position, the rotary push ball 11 moves away, and the embedded spring rod 9 springs into the slot 8, completing the locking.

[0038] When the clamping auxiliary mechanism is in operation, it provides stable rotation and final fixation of the rotating sleeve 10. The bottom of the rotating sleeve 10 is equipped with a positioning plate 12, which cooperates with the positioning spring 14 on the outer wall of the clamping tube 6. Different positioning springs 14 are embedded into different positioning plates 12 in stages to ensure stable rotation of the rotating sleeve 10. The threaded ring 13 is threadedly connected to the outer wall of the clamping tube 6. The push plate 15 at its bottom contacts the push plate 17 at the top of the clamping ring 16. When the threaded ring 13 is rotated, the push plate 15 pushes the push plate 17, causing the clamping ring 16 to move longitudinally, and finally firmly fixes the rotating sleeve 10 to the outer wall of the clamping tube 6 to prevent loosening during the processing.

[0039] The parts to be processed are placed on the module plate 19 on the support frame 18 at the top of the main frame 1. The side plates 21 on both sides of the module plate 19 are connected to the mounting plates 20 on both sides of the support frame 18 through the template snap-fit ​​mechanism. Specifically, the snap-fit ​​rod 7 is inserted through the mounting plate 20 into the snap-fit ​​tube 6 fixed on the side plate 21. The rotating sleeve 10 on the outer wall of the snap-fit ​​tube 6 is rotated, so that the embedded spring rod 9 springs into the snap-fit ​​groove 8 of the snap-fit ​​rod 7, achieving initial locking. The threaded ring 13 is rotated, and the pressing ring 16 is pushed by the rotary push plate 15, so that the rotating sleeve 10 is locked. 0 is firmly fixed to the outer wall of the clamping pipe 6 to ensure a stable connection of the module plate 19. The hydraulic cylinder 24 is activated to drive the push-pull block 2 to move. Through the rotational connection of the first rotating block 5 and the second rotating block 101, the pressure block 3 rotates downward and presses against the part on the module plate 19, firmly clamping it. After the part is fixed, various processing operations can be performed. After processing is completed, the hydraulic cylinder 24 moves in the opposite direction to release the pressure, and the pressure block 3 is lifted. The rotating sleeve 10 is rotated to make the embedded spring rod 9 exit the clamping slot 8, the module plate 19 can be detached, and the processed part can be taken out.
