Description

Technical Field

[0001] The utility model relates to the technical field of metal parts processing, in particular to a clamping assembly for metal parts processing. Background Art

[0002] Metal parts processing refers to the use of various mechanical equipment and process methods to cut, form, weld, grind and other processing processes on metal materials to produce metal parts that meet design requirements. Metal parts are widely used in various fields such as automobiles, aerospace, mechanical equipment, and electronic products. Mechanical parts processing fixtures are tools used to clamp workpieces and fix them on machine tools for precision processing. The fixture plays a role in fixing the position of the workpiece and improving processing accuracy and efficiency in mechanical processing. It is an indispensable auxiliary tool in mechanical processing.

[0003] Traditional clamping assemblies for metal parts processing are usually clamped and fixed by a fixed clamp block and a movable clamp block. This fixing method cannot keep the center point of the part roughly in the same position, so the tool stroke will be longer during processing, making it inconvenient to control the processing equipment to process it.

[0004] Therefore, those skilled in the art provide a clamping assembly for metal parts processing to solve the problems raised in the above background technology. Utility Model Content

[0005] The utility model aims to solve the shortcomings existing in the prior art, and proposes a clamping assembly for metal parts processing. The device drives a small driving gear to rotate through the operation of a motor, and the small driving gear drives a large driven gear to rotate, thereby obtaining a larger torque. The driving gear drives a double-headed threaded screw to rotate, so that two clamping blocks move inwards simultaneously along the direction of the slide bar to clamp the metal parts, thereby achieving that the center point of the metal parts is approximately located at the center of the frame when being fixed, which can facilitate processing and shorten the tool setting stroke of the processing machine.

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

[0007] A clamping assembly for processing metal parts comprises a frame, a double-threaded screw is rotatably arranged at the front end of the frame, a sliding rod is fixedly arranged at the rear end of the frame, clamping blocks are threadedly sleeved on both sides of the double-threaded screw, and the rear ends of the two clamping blocks are slidably connected to the sliding rod, a motor is fixedly arranged on one side of the front end surface of the frame, a driving gear is fixedly arranged on the output end of the motor, a driven gear is fixedly arranged on the side of the double-threaded screw close to the motor, and the driving gear is meshed with the driven gear.

[0008] Through the above technical solution, the two clamping blocks can be driven by the rotation of the double-headed threaded screw to move simultaneously along the direction of the slide rod to clamp the metal parts, so that the center point of the fixed part is approximately located at the center of the frame, which can facilitate the processing of the tool by the processing machine, and the device drives the small driving gear and the large driving gear to rotate through the motor, so as to obtain a larger torque and make the clamping more stable.

[0009] Furthermore, a slide groove is provided on one side of the bottom of the frame body, a chip suction box is provided at the bottom of the frame body, a limit plate is fixedly provided on the top of the chip suction box, and the limit plate is slidably connected to the slide groove;

[0010] Through the above technical solution, the chip suction box can be quickly installed and disassembled through the slide groove and the limit plate.

[0011] Furthermore, an iron bottom shell is fixedly arranged at the bottom of the dust suction box, a strong magnet is arranged at the bottom of the iron bottom shell, and the strong magnet is magnetically connected to the iron bottom shell;

[0012] Through the above technical solution, a strong magnet is set at the bottom of the bottom shell. Due to the conductivity of the magnet, the magnetism can be transferred to the iron bottom shell. The iron bottom shell can absorb the iron filings and dust generated by the processing, so that the waste can be concentrated for later processing.

[0013] Furthermore, support blocks are fixedly arranged at the four corners of the bottom end of the frame, mounting blocks are fixedly arranged on the outer sides of the four support blocks, and mounting holes are opened in the middle of the four mounting blocks;

[0014] Through the above technical solution, screws can be inserted through the mounting block and the mounting holes on the mounting block to fix the clamp.

[0015] Furthermore, the opposite sides of the two clamping blocks are in a 120-degree groove shape, and rubber pads are fixedly arranged on the opposite sides of the two clamping blocks;

[0016] Through the above technical solution, the rubber pad can increase the friction and play a buffering role to prevent the fixture from scratching the surface of the part.

[0017] Furthermore, a handle is fixedly provided on one side of the dust suction box;

[0018] Through the above technical solution, the chip suction box can be easily pulled out through the handle, making it easier to exert force.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model proposes a clamping assembly for metal parts processing. The device drives a small driving gear to rotate through the operation of a motor, and the small driving gear drives a large driven gear to rotate, thereby obtaining a larger torque. The driving gear drives a double-headed threaded screw to rotate, so that two clamping blocks move inwards simultaneously along the direction of the slide bar to clamp the metal parts, thereby achieving that the center point of the metal parts is approximately located at the center of the frame when being fixed, which is convenient for processing and shortens the tool setting stroke of the processing machine.

[0021] 2. The utility model proposes a clamping assembly for metal parts processing. After the metal parts are fixed, the strong magnet at the bottom cooperates with the iron bottom shell to absorb the metal chips generated during processing, so that they are adsorbed on the iron bottom shell, which can concentrate the iron chips and iron dust for later centralized processing. The chip suction box can be pulled out through the handle, and the strong magnet can be disassembled to dump the internal waste, which is easy to operate and use. BRIEF DESCRIPTION OF THE DRAWINGS
