Technical Field

[0001] The utility model relates to the technical field of cutting clamps, in particular to a clamp for a cutting machine with multi-angle adjustment. Background Art

[0002] A cutting machine is a mechanical device used to cut various materials. Common cutting machines include laser cutting machines, plasma cutting machines, water jet cutting machines, etc. A cutting machine cuts materials through high-energy beams, plasma arcs or high-pressure water flows, and is used to process various materials such as metals, plastics, and wood. A cutting machine fixture is a device used to fix and clamp the cut material, which is used to ensure that the cut material remains stable during the cutting process and prevent the material from moving or shaking, thereby ensuring the cutting quality and safety. A cutting machine fixture is usually composed of a clamp, a fixture bed, a fixture holder, etc., which can be adjusted and fixed according to the shape and size of the cut material. Using a cutting machine fixture can improve cutting efficiency, accuracy, and safety, and can also reduce material waste and loss during the cutting process. Therefore, the cutting machine fixture plays a very important role in the cutting process.

[0003] In the prior art, the positioning process of cutting workpieces usually adopts workers holding objects for cutting, or fixing the workpieces with simple clamps. However, during the cutting process, the workpieces often need to be adjusted to various heights and angles, and this simple clamping method often cannot meet the adjustment requirements. Therefore, the utility model provides a multi-angle adjustable cutting machine clamp to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multi-angle adjustable cutting machine clamp comprises a stable base, an adjustment mechanism is fixedly arranged at the middle of the upper end of the stable base, a positioning mechanism is arranged at the upper end of the adjustment mechanism, and a padding mechanism is embedded in the middle of the positioning mechanism;

[0007] The adjustment mechanism comprises a rotating lifting base, the upper end of which is hingedly provided with four adjustment push rods, the upper ends of the four adjustment push rods are hingedly provided with adjustment blocks, and a lower support plate is fixedly provided between the four adjustment blocks;

[0008] The positioning mechanism comprises a positioning platform, the cushioning mechanism is arranged through the middle of the positioning platform, the cushioning mechanism comprises a support frame, and a cushioning plate is arranged on the upper end of the support frame for vertical sliding;

[0009] Through the above technical scheme, the fixture can clamp the workpiece through the positioning slider on the positioning mechanism during the positioning process, and the clamping height can be adjusted through the raising mechanism, so that a gap can be left under the workpiece to facilitate cutting. During the cutting process, the positioning table can also be controlled to tilt at a certain angle through the adjusting mechanism, thereby further improving the cutting effect.

[0010] Furthermore, the positioning platform is provided with stable slide grooves at the four sides, and positioning sliders are slidably arranged inside the four stable slide grooves. Electric push rods are arranged through the positioning platform near the four stable slide grooves, and opposite ends of the four electric push rods are fixedly connected to the four positioning sliders respectively.

[0011] Through the above technical solution, the electric push rod can drive the four positioning slide blocks to slide inside the stable slide groove, and then move toward the workpiece through the positioning slide block, thereby clamping and fixing the workpiece.

[0012] Furthermore, lower connecting blocks are fixedly arranged around the lower supporting plate, and four lower connecting blocks are respectively fixedly connected to the lower end of the positioning platform;

[0013] Through the above technical solution, the positioning mechanism can be supported by the lower support plate through the lower connecting block, which facilitates the adjustment mechanism to adjust the angle.

[0014] Furthermore, a support platform is fixedly arranged at the middle of the lower end of the lower support plate and the middle of the upper end of the rotating lifting base, and a stabilizing ball is rolledly arranged between the two support platforms;

[0015] Through the above technical solution, the stabilizing ball can be rotated in any direction between the two support platforms, so that the upper support platform can still be supported by the stabilizing ball after moving to any angle, thereby improving the stability of the upper positioning mechanism.

[0016] Furthermore, an adjusting screw is rotatably arranged at the middle of the lower end of the support frame, a lifting cylinder is fixedly arranged at the lower end of the pad plate, and the adjusting screw is threadedly sleeved inside the lifting cylinder;

[0017] Through the above technical solution, the adjusting screw can rotate at the inner bottom of the support frame. When the adjusting screw rotates, it can drive the upper lifting cylinder to realize the lifting function, thereby driving the raising plate to lift.

[0019] Through the above technical solution, when the adjusting rod rotates, it can drive the second bevel gear to rotate, and the second bevel gear is meshed with the first bevel gear, thereby driving the first bevel gear to rotate at the same time. Then, when the first bevel gear rotates, it will drive the adjusting screw to rotate, and finally realize the lifting and lowering of the lifting cylinder.

[0020] Furthermore, sliding rods are fixedly arranged on both sides of the lower end of the raising plate, and the raising plate is vertically slidably arranged on the upper end of the supporting frame through the two sliding rods;

[0021] Through the above technical solution, the raising plate can stably slide up and down on the upper end of the supporting frame.

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

[0023] 1. The utility model proposes a multi-angle adjustable cutting machine clamp, which has an internal adjustment mechanism that can drive the upper positioning mechanism to achieve multi-angle tilt adjustment. During the adjustment process, the angle of the lower support plate is changed by changing the length of the adjustment push rod, thereby achieving the purpose of adjusting the angle of the positioning mechanism, simplifying the cutting process and ensuring its stability. In addition, during the cutting process, the stabilizing ball can rotate freely between the two support platforms, so that the upper support platform can be supported by the stabilizing ball at any angle, thereby further improving the stability of the upper positioning mechanism.

[0024] 2. The multi-angle adjustable cutting machine clamp proposed by the utility model is equipped with a padding mechanism inside the positioning mechanism. By adjusting the rotation of the rotating rod, the second bevel gear can be rotated. In view of the meshing relationship between the second bevel gear and the first bevel gear, the first bevel gear is driven to rotate synchronously. On this basis, the rotation of the first bevel gear will trigger the movement of the adjusting screw, and finally realize the lifting and lowering control of the lifting cylinder. This design helps to conveniently adjust the clamping height and reserve sufficient space under the workpiece for cutting, thereby further improving the convenience of the cutting operation.
