Technical Field

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

[0002] In the machining industry, fixtures are crucial process equipment for ensuring workpiece machining accuracy and improving production efficiency; their performance directly impacts machining quality and production benefits. With the rapid development of the manufacturing industry, the demands for machining accuracy, efficiency, and the diversity of workpieces being processed are constantly increasing.

[0003] Currently, the clamping angles of fixtures on the market are fixed, failing to adapt to diverse processing needs. Even those fixtures that can adjust the angle are extremely cumbersome, often requiring multiple complex tools and extensive manual operation. This not only consumes significant time and manpower but also carries the risk of inaccurate angle adjustments due to operational errors, severely limiting processing flexibility and adaptability. Furthermore, once installed and fixed, their position is essentially immovable, making precise positioning according to different workpiece sizes and processing requirements difficult, thus reducing usability. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology that the fixture is not convenient to accurately adjust and position according to the size of different workpieces, and is not convenient to adjust the processing angle after clamping.

[0018] A rotating shaft is rotatably connected to the fixed plate;

[0019] A rocker arm, which is fixed to the top surface of the rotating shaft;

[0020] The worm gear is fixedly sleeved on the rotating shaft;

[0021] A worm gear, which is fixedly sleeved on the rotating rod.

[0022] Preferably, the worm and the worm wheel mesh with each other.

[0023] Preferably, the clamping mechanism includes:

[0024] A slot is formed within the mounting base;

This multi-angle adjustment function enables the fixture to handle complex and diverse machining tasks, enhancing its versatility and applicability.

[0033] 2. This utility model utilizes multiple linearly distributed first screw holes on the fixture base, along with the clamping and bolt fastening method, to flexibly adjust the position of the clamping base according to the workpiece processing requirements, achieving precise positioning.

[0040] 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.

[0041] Reference Figures 1-4A modular fixture includes a fixture base 1, a plurality of grooves 2 are provided on the top surface of the fixture base 1, a clamping seat 3 is engaged in the plurality of grooves 2, a notch 4 is provided on the top surface of the clamping seat 3, a rotating rod 5 is rotatably connected in the notch 4, a mounting seat 6 is fixed on the end side of the rotating rod 5, and a clamping mechanism is installed in the mounting seat 6, the mechanism is convenient for clamping and fixing the workpiece.

[0042] A modular clamp also includes fasteners and rotating parts.

[0043] Fasteners facilitate the secure installation of the clamp 3. The fasteners include a first screw hole 31, a second screw hole 32, and a bolt 33. The first screw hole 31 is located on the fixture base 1, and the second screw hole 32 is located on the clamp 3. The bolt 33 is threaded into the first screw hole 31 and the second screw hole 32. Multiple first screw holes 31 are linearly distributed, and two second screw holes 32 are symmetrically arranged about the clamp 3. The linear distribution of the first screw holes 31 on the fixture base 1 provides multiple options for the installation position of the clamp 3. The symmetrical arrangement of the two second screw holes 32 about the clamp 3, in conjunction with the bolt 33, ensures a more stable installation of the clamp 3 on the fixture base 1, preventing displacement of the clamp 3 during machining.

[0044] The rotating component facilitates the rotation of the rotating rod 5. It includes a fixed plate 51, a rotating shaft 52, a rocker arm 53, a worm gear 54, and a worm wheel 55. The fixed plate 51 is fixed to the clamping seat 3. The rotating shaft 52 is rotatably connected to the fixed plate 51. The rocker arm 53 is fixed to the top surface of the rotating shaft 52. The worm gear 54 is fixedly sleeved on the rotating shaft 52, and the worm wheel 55 is fixedly sleeved on the rotating rod 5. The worm gear 54 and the worm wheel 55 mesh with each other. The fixed plate 51 provides stable support for the rotating shaft 52, ensuring smooth rotation. The rocker arm 53 is designed to facilitate force application by the operator, making rotation easier. The meshing transmission of the worm gear 54 and the worm wheel 55 features a large transmission ratio and compact structure, enabling precise angle adjustment to meet the diverse clamping angle requirements of different workpieces.

[0045] The clamping mechanism includes a slot 61, a double-ended screw 71, a slider 7, and a clamping plate 8. The slot 61 is located within the mounting base 6. The double-ended screw 71 is installed within the slot 61. The slider 7 is threadedly connected to the double-ended screw 71. The clamping plate 8 is fixed to the end of the slider 7. An anti-slip pad is adhered to the inner wall of the clamping plate 8. The double-ended screw 71 is rotatably connected to the mounting base 6. The double-ended screw 71 has symmetrically arranged reverse-facing threaded grooves. Two sliders 7 and two clamping plates 8 are symmetrically arranged about the double-ended screw 71. The internal connections between the two sliders 7 and the double-ended screw 71 have external threads that mate with the screw threads. The two sliders 7 slide in the same direction. The slot 61 provides installation space for the double-ended screw 71, sliders 7, and clamping plate 8. The double-ended screw 71 is rotatably connected to the mounting base 6, ensuring its free rotation. The two sliders 7 slide in the same direction, ensuring the symmetry of the clamping plate 8's grip on the workpiece and preventing damage to the workpiece due to uneven clamping force. The anti-slip mat is fixed to the inner wall of the clamping plate 8 by adhesive bonding, which is convenient to install and effectively prevents the workpiece from sliding during processing.

[0046] The functional principle of this utility model can be explained through the following operation methods:

[0047] When using this fixture, first, the clamping seat 3 is engaged in the groove 2 on the top surface of the fixture base 1, aligning the second screw hole 32 on the clamping seat 3 with the corresponding first screw hole 31 on the fixture base 1. Then, the clamping seat 3 is secured to the fixture base 1 by screwing the bolts 33 into the first screw hole 31 and the second screw hole 32. Since there are multiple first screw holes 31 linearly distributed, the position of the clamping seat 3 on the fixture base 1 can be flexibly adjusted according to the processing requirements of the workpiece to achieve precise positioning.

[0048] The workpiece is then placed between the two clamping plates 8. The double-ended screw 71 is rotated, and the two sliders 7 slide in opposite directions and synchronously along the double-ended screw 71. The sliding of the sliders 7 drives the clamping plates 8 on the end side to move. The two clamping plates 8 move closer or further away from each other, thereby clamping or releasing the workpiece.

[0049] When the angle of the clamping mechanism needs to be adjusted, the rocker arm 53 is rotated, which drives the rotating shaft 52 to rotate. The worm gear 54 sleeved on the outside of the rocker arm 53 rotates synchronously. When the worm gear 54 rotates, it meshes with the worm wheel 55, thereby driving the worm wheel 55 to rotate. The worm wheel 55 then drives the rotating rod 5 to rotate, thus realizing the adjustment of the angle of the mounting base 6 and the clamping mechanism inside the mounting base 6 to adapt to the clamping requirements of workpieces with different shapes.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
