Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a processing clamp with good stability. Background Art

[0002] Aluminum alloy workpiece fixture is a tool or device used to clamp and fix aluminum alloy workpieces. It is usually made of metal and has a specific shape and structure to ensure that the workpiece maintains a stable position and posture during the processing. The main function of aluminum alloy workpiece fixture is to fix the workpiece to ensure processing accuracy and improve work efficiency during processing, assembly or other process operations. At the same time, it can also protect the surface of the workpiece to avoid damage or deformation during the process.

[0003] Existing aluminum alloy workpieces are often clamped and fixed by screws during the clamping process. This clamping and fixing method is difficult to achieve high positioning accuracy, especially in applications that require extremely fine processing. The accuracy may be reduced due to the slight looseness of the screw. When subjected to heavy loads or high-speed movement, screw clamping alone may not provide sufficient stability, and vibration or displacement of the workpiece may easily occur. Screw clamping often applies concentrated force at the contact point, which may cause stress concentration near the clamping point, thereby damaging or deforming the workpiece, especially for brittle materials or thin-walled components. For workpieces of certain shapes or sizes, the clamping method using only screws may not be ideal and needs to be supplemented by additional adapters or fixtures.

[0004] Therefore, the utility model provides a processing fixture with good stability to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a processing fixture with good stability. The fixture provided by the utility model has high positioning accuracy, strong stability and rigidity, and a more uniform and firm clamping force.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A processing fixture with good stability, comprising a clamping body mechanism and a control mechanism, wherein the clamping body mechanism comprises a C-shaped clamping frame, two clamping grooves are provided on one side of the C-shaped clamping frame, extension rods are hingedly provided inside the two clamping grooves near the openings, the clamping rods are fixedly provided on the ends of the two extension rods away from the C-shaped clamping frame, trapezoidal push blocks are fixedly provided on the opposite ends of the two extension rods, limited slots are provided at the centers of the opposite sides of the two trapezoidal push blocks, and fixing holes are provided at the centers of the sides of the C-shaped clamping frame away from the clamping rod;

[0008] The control mechanism comprises an externally threaded rod, one end of which is fixedly provided with a triangular push block, the upper end face and the lower end face center of the triangular push block are fixedly provided with limit clamping strips, an internally threaded sleeve is threadedly sleeved on the rod body of the externally threaded rod away from the triangular push block, and a positioning bearing is fixedly sleeved in the middle of the internally threaded sleeve body;

[0009] Through the above technical solution, the clamp provided in the utility model has high positioning accuracy, strong stability and rigidity, and a more uniform and firm clamping force.

[0010] Furthermore, a clamping plate is fixedly provided on one side of the two clamping rods away from one end of the C-shaped clamping frame, and clamping teeth are provided on one side of the two clamping plates opposite to each other;

[0011] Through the above technical solution, the two clamping plates are brought closer to each other to achieve clamping.

[0012] Furthermore, one of the two clamping teeth is arranged longitudinally and the other is arranged transversely;

[0013] Through the above technical solution, the bidirectional setting increases the friction force and the clamping is more stable.

[0014] Furthermore, the triangular push block is located between the two trapezoidal push blocks, and the limit card strip is movably arranged inside the limit card slot;

[0015] Through the above technical solution, the limiting card strip is arranged inside the limiting card slot to increase the stability of clamping and the stability of displacement.

[0016] Furthermore, the positioning bearing fixing sleeve is arranged inside the fixing hole;

[0017] Through the above technical solution, a positioning bearing is provided to increase the stability of rotation.

[0018] Furthermore, a hand wheel is fixedly sleeved on one end of the internal threaded sleeve away from the triangular push block;

[0019] Through the above technical solution, the hand wheel can be easily rotated.

[0020] Further, the trapezoidal push block has the same inclination as the trapezoidal push block;

[0021] Through the above technical solution, the fit is higher when the inclination is the same.

[0022] The utility model has the following beneficial effects:

[0023] The utility model proposes a processing fixture with good stability. When the utility model is in use, the dovetail structure under the cooperation of the triangular push block and the trapezoidal push block can achieve high-precision positioning by controlling the external threaded rod and the internal threaded sleeve. The dovetail structure can accurately control the position of the workpiece. The dovetail groove allows the fixture to move smoothly along a specific trajectory. This is because the dovetail shape can naturally resist lateral and vertical movement, thereby ensuring the precise positioning of the workpiece. The dovetail structure can enhance the stability during clamping due to its staggered design. This structure is particularly suitable for operations that withstand high rotation speeds and heavy cutting loads because it can effectively resist vibration and sliding. Compared with simple screw clamping, the dovetail structure can distribute the clamping force more evenly, reduce local stress on the workpiece, and avoid deformation or damage. The combination of the screw increases the flexibility of the dovetail structure, and the screw can be adjusted to adapt to workpieces of different sizes while maintaining precise control.

[0034] The clamp provided in the utility model has high positioning accuracy, strong stability and rigidity, and a more uniform and firm clamping force. A clamping plate 106 is fixedly provided on one side of the two clamping rods 107 away from one end of the C-shaped clamping frame 101, and clamping teeth 105 are provided on the opposite side of the two clamping plates 106. The two clamping plates 106 are close to each other to achieve clamping, and one of the two clamping teeth 105 is longitudinally arranged and the other is transversely arranged.

[0035] The two-way setting increases friction and makes the clamping more stable. The triangular push block 202 is located between the two trapezoidal push blocks 103, and the limit strip 201 is movably arranged inside the limit slot 104. The limit strip 201 is arranged inside the limit slot 104 to increase the stability of clamping and the stability of displacement. The positioning bearing 205 is fixedly sleeved inside the fixing hole 102. The positioning bearing 205 is arranged to increase the stability of rotation.

The inclination of the trapezoidal push block 103 is the same as that of the trapezoidal push block 103, and the same inclination has a higher fit.

[0036] High positioning accuracy and stability

[0037] Use of dovetail structure: The dovetail structure of the triangular push block 202 and the trapezoidal push block 103 allows the fixture to move smoothly along a specific trajectory, naturally resisting horizontal and vertical movement. Limiting card strip 201: The limiting card strip 201 movably arranged on the triangular push block 202 is located in the limiting card slot 104 of the trapezoidal push block 103 to improve dynamic stability.

[0038] Strong clamping and evenly distributed pressure

[0039] Design of clamping teeth 105 and clamping plate 106: The design of clamping teeth 105 and clamping plate 106 with transverse and longitudinal directions realizes multi-directional fixing and improves the clamping effect.

[0040] Flexibility and adaptability

[0041] Hand wheel 206 and thread adjustment system: Use hand wheel 206 in conjunction with internal thread sleeve 204 and external thread rod 203 to complete precise adjustment to adapt to various workpieces.

[0050] These technical features confirm the efficiency and practicality of this processing fixture, which is particularly suitable for industrial occasions that require precise control and high stability.

[0051] Working principle: When in use, turn the handwheel 206, and the rotation of the handwheel 206 drives the internal threaded sleeve 204 to rotate in the positioning bearing 205. When the internal threaded sleeve 204 rotates, the external threaded rod 203 makes a linear motion, thereby driving the triangular push block 202 to move to one side or the other side. When the triangular push block 202 moves closer to the handwheel 206, due to the design of the italic structure, the triangular push block 202 pushes the trapezoidal push block 103 upward. When the trapezoidal push block 103 is pushed upward, under the action of the hinge, the two clamping plates 106 can be brought closer to each other to achieve the clamping of the aluminum alloy workpiece.
