Especially for special-shaped workpieces, the traditional clamping device is difficult to achieve stable and reliable clamping, and is prone to displacement and loosening of the workpiece during the machining process, thereby causing poor machining surface quality and difficult-to-ensure dimensional accuracy, and even possibly causing the workpiece to be scrapped, thereby increasing the production cost.

[0016] The following will be described in detail with reference to the accompanying drawings Figs. 1-3 The application will be further described in detail.
[0017] The embodiment of the application discloses a machining clamping device. Referring to Figs. 1-3 A machining clamping device mainly comprises a tiltable base 1, a sliding table 2, a fixed jaw body 3, a movable assembly 4, an adjustable pad 5 and jaw teeth 6, realizes accurate and stable clamping of workpieces of different shapes and sizes, and can flexibly adjust the clamping angle to meet the diversified machining process requirements.
[0018] Referring to Fig. 1 The tiltable base 1 is used as the basic support and angle adjusting component of the whole clamping device, is made of high-strength cast iron material, and the mounting plane and positioning pin hole at the bottom ensure that it can be accurately connected with the workbench. The internal precise transmission components, such as the high-precision screw, nut pair and worm gear assembly, realize the accurate inclination adjustment of the sliding table 2 from the horizontal position to the vertical position or other required angles in the horizontal direction, meet the requirements of different postures of workpieces in various machining processes such as milling, drilling and grinding, and greatly expand the application range of the device.
[0019] Referring to Fig. 2The slide table 2 is made of high-quality aluminum alloy, and its high-precision guide rail on the upper surface provides a smooth and accurate sliding guide for the fixed clamp body 3 and the moving component 4, which effectively reduces frictional resistance and positioning error during movement, ensures the positional accuracy of the workpiece during clamping, and thus improves the consistency of processing accuracy and product quality.
[0020] refer to Fig. 2 The movable component 4 consists of a screw 401 and a movable clamp body 402. The screw 401 is made of high-strength threaded steel with high thread precision, which fits tightly with the threaded hole of the movable clamp body 402, driving the movable clamp body to move smoothly to achieve the clamping action. It has good wear resistance and fatigue resistance, ensuring stable and reliable clamping force, reducing downtime and processing errors. A fixed seat is fitted on the screw 401, which is detachably connected to the slide table 2, such as by bolts or dovetail joints, which facilitates installation, adjustment and maintenance. It allows operators to easily replace or fine-tune the movable component 4 according to processing needs, improving the flexibility and adaptability of the device.
[0021] Reference Fig. 3 The fixed clamp body 3 and the movable clamp body 402 are made of high-strength alloy steel. The rotating grooves on the fixed clamp body 3 and the movable clamp body 402 are manufactured using precision machining technology. The diameter and depth of the grooves are precisely matched with the clamping block 601, ensuring that the clamping block 601 can rotate flexibly within the rotating groove to adapt to changes in the shape of the workpiece. At the same time, it avoids excessive gaps that may affect the clamping accuracy, enabling the jaws 6 to clamp the workpiece tightly and stably. Reliable clamping can be achieved for both regular and irregular shaped workpieces, improving the versatility and adaptability of the device for different workpieces and meeting diverse processing needs.
[0022] refer to Fig. 3 The jaws 6 consist of a clamping block 601 and an anti-slip pad 602. The crescent-shaped design of the clamping block 601 adapts to the surface contour of the workpiece, providing uniform clamping force, preventing workpiece damage, and ensuring machining accuracy and stability. The anti-slip pad 602 is made of a high-friction coefficient material and is fixed to the surface of the clamping block 601 by bonding or vulcanization processes, enhancing the clamping stability of the workpiece. It is particularly effective for workpieces with smooth or inclined surfaces, preventing workpiece slippage during machining.
[0023] refer to Fig. 3 The adjustable pad 5 consists of a threaded rod 501 and a pad block 502. The threaded rod 501 is made of threaded steel and fits tightly with the threaded hole of the pad block 502, allowing for flexible rotation and precise adjustment of the pad block position to meet the height requirements of workpieces of different thicknesses, thus expanding the device's clamping capacity for workpieces of different sizes. The pad block 502 is made of aluminum alloy or engineering plastic, is lightweight yet possesses a certain strength and hardness, and its surface is precision-machined to ensure flatness and roughness meet requirements, preventing scratches on the workpiece surface.
[0024] The implementation principle of a machining clamping device according to an embodiment of this application is as follows:
[0025] The workpiece to be processed is placed between the fixed clamp 3 and the movable clamp 402, so that one side of the workpiece initially contacts the jaws 6 on the fixed clamp 3. Then, the operator uses a wrench or other tools to turn the screw 401. The rotation of the screw 401 drives the movable clamp 402 to move towards the fixed clamp 3 along the guide rail on the slide table 2. As the movable clamp 402 approaches, the jaws 6 on it gradually contact the other side of the workpiece. Since the clamping block 601 of the jaw 6 is crescent-shaped and rotatably set in the rotating groove by a pin, when the clamping block 601 contacts the side of the workpiece, as the movable clamp 402 continues to advance, the clamping block 601 will rotate around the pin under the pressure of the workpiece, automatically adjusting its angle to closely fit the surface contour of the workpiece. Whether it is a regular shape such as a plane, cylinder, or curved surface, or various irregular irregular surfaces, good contact and clamping can be achieved, effectively preventing the workpiece from shifting or rotating during processing, and ensuring processing accuracy and surface quality.
[0026] While clamping the workpiece, the operator uses a tool to rotate the threaded rod 501 of the adjustable shim 5 according to the workpiece's thickness. The rotation of the threaded rod 501 causes the shim block 502 to move within the receiving groove of the fixed clamp body 3, thereby adjusting the workpiece's height. Raising the workpiece to a suitable height ensures that the workpiece's machining area is in the optimal machining position, meeting the height requirements of different machining processes and further improving the device's versatility and adaptability.
