Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a flip cover clamping mechanism. Background Technology

[0002] For small product testing (such as tensile testing) or processing auxiliary positioning scenarios, it is necessary to use fixtures to stably hold the product to ensure the accuracy of subsequent operations. In the existing technology, conventional clamping methods mostly rely on independent fixture components. That is, the product is first constrained laterally and vertically by a fixture consisting of multiple sets of positioning blocks, bolts or pneumatic grippers, and then the clamped product and fixture are transferred together to the working platform such as tensile testing equipment, or a complex fixture structure is additionally installed on the equipment.

[0003] On the one hand, the fixture components have a large number of parts and complicated assembly steps. Each time a product is clamped, the position of the positioning block needs to be adjusted repeatedly, the bolts tightened, or the pneumatic components adjusted. The operation is time-consuming and wastes time. On the other hand, the fixtures have high compatibility requirements with the equipment. Different specifications of products require the corresponding fixtures to be replaced. The switching process is complicated, and the fixtures themselves occupy the equipment's working space, which can easily interfere with the testing or processing operations. This seriously limits the improvement of testing capacity and makes it difficult to meet the needs of efficient and batch production operations. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a flip-top clamping mechanism.

[0005] This utility model proposes a flip-top clamping mechanism, including a fixture base. The top of the fixture base has a work station groove to constrain the lateral position of the product. One side of the fixture base is rotatably connected to a cover plate to constrain the vertical position of the product. The top of the other side of the fixture base is equipped with a cover pressing module to prevent the cover plate from flipping freely. The cover pressing module includes a frame body fixed to the top of the fixture base. The frame body has a locking tongue and a locking handle movably arranged inside. The locking tongue rotates to drive the locking tongue to extend out of the frame body and engage with the cover plate.

[0006] Furthermore, a U-shaped clearance groove is provided on the other side of the workstation slot. The first rotating shaft is connected inside the clearance groove. A fifth through hole is provided at the bottom of the lock handle. The first rotating shaft is inserted into the fifth through hole to rotate relative to it.

[0007] Furthermore, a handle is installed at the top of the cover to facilitate flipping the cover.

[0008] Furthermore, a cavity is formed inside the frame body, and the latch moves laterally inside the cavity. Corresponding first through holes are formed at the top and bottom of the frame body, and a fourth through hole is formed inside the latch. The lock handle is inserted into the first and fourth through holes. A second rotating shaft is connected through the middle of the latch. Corresponding second through holes are formed on both sides of the frame body, and the second rotating shaft moves laterally inside the second through holes.

[0009] Furthermore, a sixth through hole and a pin hole are respectively opened inside the lock handle. The second rotating shaft is inserted into the sixth through hole and is relatively movable. A third through hole is opened on both sides of the frame body and above the second through hole. A pin is inserted into the third through hole and the lock handle.

[0010] Furthermore, the second and sixth through holes are both designed as elongated holes, the length of which is adapted to the lateral sliding stroke of the second rotating shaft, and the lengths of the first and fourth through holes are adapted to the swing stroke of the lock handle.

[0011] Furthermore, a base is symmetrically mounted on the top of the fixture base, and the base presses down on the bottom feet of the frame body to fix the frame body.

[0012] The beneficial effects of this utility model are as follows: the work station slot of the fixture base realizes the lateral constraint of the product, and the cover plate realizes the vertical constraint. With the locking tongue and locking handle of the pressure cover module, the product can be quickly locked and formed into an integrated clamping structure. The product can be clamped directly on the working platform such as tensile equipment by pressing the cover plate. There is no need to rely on conventional multi-component fixtures and cumbersome assembly and adjustment steps, which greatly simplifies the product clamping operation process, saves time significantly, and effectively improves the testing capacity. At the same time, the structure is compact, easy to operate and highly adaptable, and can stably meet the high-efficiency clamping needs of small products in testing, processing and other scenarios.

[0015] Reference Figure 1-5 The present invention proposes a flip-top clamping mechanism, including a fixture base 1. At the top of the fixture base 1, a work station groove 11 adapted to the shape of the product 4 to be clamped is provided. The work station groove 11 can form a lateral limiting constraint on the product 4 placed therein, preventing the product 4 from being displaced along the horizontal direction of the fixture base 1 during the clamping process. At the same time, on one side of the work station groove 11 (corresponding to the mounting side of the cap module 3), a "U"-shaped clearance groove 12 is provided. A first rotating shaft 13 is fixedly connected inside the clearance groove 12. The first rotating shaft 13 is used to realize the rotational cooperation with the locking handle 33 in the cap module 3, providing a rotation fulcrum for the swinging action of the locking handle 33. One side of the fixture base 1 (the side away from the capping module 3) is rotatably connected to the cover plate 2. The cover plate 2 can be flipped up to open or flipped down to close around this rotatable connection point. When the cover plate 2 is flipped down to fit the top of the product 4, it can form a vertical limiting constraint on the product 4. Combined with the lateral constraint of the work station slot 11, the product 4 is initially positioned on the fixture base 1. In order to facilitate the operator to manually flip the cover plate 2, a handle 21 is fixedly installed on the top of the cover plate 2. Force can be easily applied through the handle 21, reducing the difficulty of opening and closing the cover plate 2 and improving the convenience of operation. To prevent the cover plate 2 from flipping freely after closing and to ensure that the product 4 is always in a stable clamped state, a pressure cap module 3 is installed at the top of the other side of the fixture base 1 (the side corresponding to the clearance groove 12). The pressure cap module 3 consists of a frame body 31, a locking tongue 32, a locking handle 33, a base 34, a pin 35, and a second rotating shaft 322. The frame body 31 is pressed and fixed by the base 34 symmetrically installed at the top of the fixture base 1. The base 34 can effectively limit the horizontal and vertical displacement of the frame body 31 and ensure the assembly stability between the frame body 31 and the fixture base 1. The frame body 31 has a cavity 311 inside for accommodating the latch 32. The latch 32 can move laterally in the horizontal direction within the cavity 311 (moving towards the cover plate 2 for engaging and away from the cover plate 2 for unlocking). At the top and bottom of the frame body 31, there are corresponding first through holes 312. At the same time, there is a fourth through hole 321 inside the latch 32 corresponding to the position of the first through hole 312. The lock handle 33 is inserted sequentially into the first through hole 312 at the top of the frame body 31, the fourth through hole 321 of the latch 32, and the first through hole 312 at the bottom of the frame body 31, forming a linkage and cooperation structure between the lock handle 33, the latch 32, and the frame body 31. In addition, a second rotating shaft 322 is horizontally connected through the middle of the locking tongue 32. Second through holes 313 adapted to the two ends of the second rotating shaft 322 are provided on the two side walls of the frame body 31. The two ends of the second rotating shaft 322 extend into the second through holes 313 on both sides respectively, and can slide laterally along the length direction of the second through holes 313. This structure not only provides guidance for the lateral movement of the locking tongue 32, but also restricts the range of movement of the locking tongue 32, preventing the locking tongue 32 from coming out of the cavity 311 of the frame body 31. The lock handle 33 is also provided with a sixth through hole 332 and a pin hole 333. The sixth through hole 332 is adapted to the second rotating shaft 322 in the middle of the lock tongue. The second rotating shaft 322 is inserted into the sixth through hole 332 and can move relative to it along its length. Through the cooperation of the two, the swaying action of the lock handle 33 can be converted into the lateral action of the lock tongue 32. The pin hole 333 is opened in the upper area of ​​the lock handle 33. Correspondingly, on the two side walls of the frame body 31, above the second through hole 313, a third through hole 314 adapted to the pin hole 333 is opened. When the lock handle 33 moves to the point that the lock tongue 32 is fully extended and engages the cover plate 2, the axis of the third through hole 314 and the pin hole 333 coincides. At this time, the pin 35 is inserted into the two to lock the position of the lock handle 33 and prevent it from accidentally swaying and causing the lock tongue 32 to retract and unlock. To ensure smooth and interference-free operation of all moving parts, the shape of the key through holes has been adapted. The second through hole 313 and the sixth through hole 332 are both designed as elongated oval holes, and their length is adapted to the maximum lateral sliding stroke of the second rotating shaft 322 to avoid restricting the movement of the second rotating shaft 322. The length of the first through hole 312 and the fourth through hole 321 is adapted to the maximum swing stroke of the lock handle 33 around the first rotating shaft 13 to prevent the lock handle 33 from getting stuck on the through hole wall when it swings.

[0016] The work process is as follows: First, pull out the pin 35, turn the lock handle 33 to the right, and through the cooperation of the second rotating shaft 322 and the sixth through hole 332, drive the lock tongue 32 to retract along the cavity 311 in the direction away from the cover plate 2 until the lock tongue 32 is completely retracted into the cavity 311; then hold the handle 21 and flip the cover plate 2 upward to fully expose the work station slot 11. The product 4 to be clamped is placed in the work station slot 11 of the fixture base 1, and the horizontal positioning of the product 4 is achieved by using the lateral constraint of the work station slot 11. Hold the handle 21 and flip the cover plate 2 downwards until the bottom of the cover plate 2 is in contact with the top of the product 4, thereby achieving vertical constraint of the product 4 through the cover plate 2; Move the lock handle 33 to the left, push the lock tongue 32 along the cavity 311 towards the cover plate 2 until the end of the lock tongue 32 engages with the edge of the cover plate 2. Finally, insert the pin 35 into the third through hole 314 and the pin hole 333 to lock the lock handle 33. At this time, the product 4 is fixed by the horizontal and vertical double constraints and the pressure cap, and can be processed or tested.

[0017] When product 4 needs to be removed, first pull out the pin 35, turn the lock handle 33 to the right to drive the lock tongue 32 back into the cavity 311, release the locking constraint on the cover plate 2, then hold the handle 21 and flip the cover plate 2 upward to remove product 4.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
