Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, specifically a workpiece clamping device for mechanical manufacturing. Background Technology

[0002] Mechanical manufacturing is an industrial production activity that transforms raw materials or semi-finished products into mechanical parts, components, or complete mechanical products with specific shapes, sizes, and performance through processes such as design, processing, and assembly. In mechanical manufacturing, workpiece clamping devices are core tools for ensuring processing accuracy and improving production efficiency. They come in various types, and their design must take into account accuracy, rigidity, ease of operation, and economy.

[0003] Existing workpiece clamping devices for mechanical manufacturing often lack self-adaptive capabilities during use. Firstly, they cannot adapt to workpieces of different specifications, making it inconvenient to clamp workpieces of different sizes. Secondly, they cannot adapt to workpieces of different shapes, making it inconvenient to clamp workpieces with irregular shapes. Because some workpieces have irregular shapes, simple clamping plates or blocks cannot fit the surface of the workpiece, causing the workpiece to easily shift after clamping, resulting in workpiece damage and, in severe cases, safety hazards.

The clamping block 212 can adapt to workpieces of different shapes, ensuring that the clamping block 212 can be in close contact with the surface of the workpiece. The clamping block 212 can be fixed by inserting the card block 216 into the card slot 214, which is convenient for clamping workpieces of different shapes in the future.

[0018] Reference Figure 6A flipping frame 3 is fixedly connected to the front and rear sides of the bottom of the base 201. One end of the flipping frame 3 is rotatably connected to the mounting shell 4 via a rotating shaft. The bottom of the mounting shell 4 is fixedly connected to the base plate 1. A cylinder 5 is fixedly connected to the top of the base plate 1 and to the opposite side of the two mounting shells 4. An adjusting block 6 is fixedly connected to the output end of the cylinder 5. An adjusting frame 7 is rotatably connected to the surface of the adjusting block 6 via a rotating shaft. One end of the adjusting frame 7 is rotatably connected to the bottom of the base 201 via a rotating shaft. By setting the mounting shell 4, the installation of the flipping frame 3 can be facilitated. By setting the rotating shaft, the installation and use of the adjusting frame 7 and the flipping frame 3 can be facilitated. By setting the cylinder 5, it can be used to drive the adjusting block 6 to move. Reference Figure 1 , Figure 3 , Figure 4 and Figure 6 Mounting holes 8 are provided at the four corners of the top of the base plate 1. Two support blocks 9 are fixedly connected to the rear side of the top of the base plate 1. The top of the support blocks 9 contacts the bottom of the base 201. A handwheel 218 is fixedly connected to the top of the second screw 217. The surface of the second screw 217 is connected to the frame 209 by threads. The mounting holes 8 facilitate the fixing of the base plate 1. The support blocks 9 support the base 201. The handwheel 218 facilitates the user to rotate the second screw 217. Reference Figure 2 , Figure 3 and Figure 4 The movable frame 202 is L-shaped, and there are several springs 211. One end of the first screw 204 is rotatably connected to the inner wall of the base 201 through a first bearing, and one end of the second screw 217 is rotatably connected to the top of the lifting plate 215 through a second bearing. By setting the springs 211, it is easy to reset the clamping block 212 and ensure that the clamping block 212 is in close contact with the surface of the workpiece. By setting the first bearing, one end of the first screw 204 can be supported, improving the stability of the first screw 204 and facilitating the rotation of the first screw 204. The second bearing facilitates the connection between the second screw 217 and the lifting plate 215 and also facilitates the rotation of the second screw 217.

[0019] Working principle: The workpiece to be processed is placed on top of the base 201 and between the two movable frames 202. Then, the second screw 217 is rotated by the handwheel 218. The rotation of the second screw 217 drives the lifting plate 215 to move upward. The lifting plate 215 drives the locking block 216 to move upward and move it out of the slot 214, releasing the restriction on the movable block 210. Then, the motor 203 is controlled to run, driving the first screw 204 to rotate. The rotation of the first screw 204 can drive the two screw sleeves 205 to move towards the middle. The screw sleeves 205, through the cooperation of the sliding sleeve 207 and the connecting block 208, can drive the two movable frames 202 to move towards the middle. The movable frames 202 drive the clamping block 212 to move closer to the workpiece. As the movable frames 202 continue to move, due to... The design of spring 211 ensures that the moving block 210, which is in close contact with the workpiece, will not move, while the clamping block 212, which is not in contact with the workpiece, can continue to move until all clamping blocks 212 are in contact with the workpiece surface. Then, the reverse handwheel 218 drives the locking block 216 to insert into the locking slot 214, which can fix the moving block 210 and the clamping block 212. Multiple clamping blocks 212 are designed to adapt to workpieces of different shapes, ensuring the stability of clamping workpieces of different shapes and clamping workpieces of different specifications. When it is necessary to adjust the processing angle of the workpiece, the cylinder 5 can be controlled to move the adjusting block 6. The adjusting block 6, in cooperation with the adjusting frame 7, can drive the base 201 to tilt. By adjusting the angle of the base 201, the angle of the workpiece can be adjusted, which facilitates the subsequent processing of the workpiece.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
