Description

Technical Field

[0001] This utility model belongs to the field of CNC tool processing technology, and in particular relates to a polishing device for CNC tool processing that prevents chip splashing. Background Technology

[0002] As the core execution component of CNC machine tools, CNC cutting tools can be divided into various types such as turning tools, milling cutters, boring tools, and drill bits, depending on different machining processes such as turning, milling, boring, and drilling. The manufacturing materials include high-speed steel, cemented carbide, ceramics, cubic boron nitride, etc., and they have key characteristics such as hardness higher than the workpiece material, strong wear resistance, and good hot hardness. In practical applications, it is necessary to scientifically select the type of tool according to the hardness of the workpiece material, the machining accuracy requirements, and the process type. During tool production, the raw material is first subjected to preliminary rough machining such as forging or rolling. After rough machining, in order to improve the surface finish, reduce cutting resistance, and enhance wear resistance, the tool surface needs to be polished. At present, mechanical polishing process is mostly used, which uses a motor to drive the polishing head to rotate at high speed to polish the tool. At the same time, an anti-splash structure is also installed to block metal chips.

[0003] However, existing polishing devices for cutting tools are not convenient for stable clamping of the tools to be polished during use. During high-speed grinding, unstable clamping can easily cause the tool to tilt, resulting in uneven grinding and thus reducing the quality of the tool. Utility Model Content

[0004] The purpose of this utility model is to provide a polishing device for CNC tool processing that prevents chip splashing. By setting up a clamping part, it solves the problem that existing tool processing polishing devices are not convenient to stably clamp the tool to be polished during use. During high-speed grinding, unstable clamping can easily cause the tool to tilt, resulting in uneven grinding and thus reducing the quality of the tool.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a polishing device for CNC tool machining that prevents chip splashing. It includes a machine body and a rotating shaft 1 rotatably connected to the inner wall of the machine body. A rotating shaft 2 is rotatably connected to the inner wall of the machine body.

[0007] Furthermore, the power unit includes two synchronous pulleys located on the left side of the machine body, with a synchronous belt fitted onto the two synchronous pulleys. A power component is located on the left side of the machine body, and a protective cover is slidably connected to the outer wall of the machine body.

The power component includes a motor sleeve fixedly connected to the left side of the machine body, with a motor fixedly connected to the inner wall of the motor sleeve. The output shaft of the motor is fixedly connected to shaft one via a coupling.

[0008] Furthermore, the clamping part includes a rotating assembly disposed within the machine body; and a plurality of gripper assemblies, all of which are located within the machine body; wherein, there are three gripper assemblies arranged in a circumferential array, and all three gripper assemblies are located within the rotating assembly.

[0009] Furthermore, the adjustment unit includes a transmission assembly disposed on the right side of the rotating shaft; and a lifting assembly disposed within the machine body; wherein the lifting assembly is located above the transmission assembly.

[0010] Furthermore, the rotating assembly includes a connecting block rotatably connected to the inner wall of the machine body. A bracket is fixedly connected to the inner wall of the connecting block. A lead screw is rotatably connected to the inner wall of the bracket. A triangular slider is slidably connected to the inner wall of the bracket. A handle is fixedly connected to the outer wall of the lead screw. The lead screw passes through the triangular slider, and the outer wall of the lead screw is threadedly connected to the triangular slider. The lead screw also passes through the handle. The right side of the rotating shaft is fixedly connected to the connecting block. Rotating the handle drives the lead screw to rotate, causing the triangular slider to move linearly along the lead screw, thereby providing a drive for the action of the gripper assembly.

[0011] Furthermore, the gripper assembly includes a limiting groove formed on the triangular slider, a limiting block is provided in the limiting groove, and a gripper is fixedly connected to the outer wall of the limiting block; wherein, the limiting groove passes through the triangular slider, the limiting block is adapted to the limiting groove, the outer wall of the gripper is slidably connected to the connecting block, when the triangular slider moves, the limiting block slides in the limiting groove, driving the gripper to slide along the connecting block, realizing the opening and closing of the gripper for grasping or releasing items.

[0012] Furthermore, the transmission assembly includes a rotating block 1 rotatably connected to the inner wall of the machine body. Two bevel gears are provided at the bottom of the rotating block 1, and a cross groove is formed on the inner wall of the rotating block 1. The outer wall of the rotating shaft 1 is fixedly connected to the lower bevel gear, and the rotating shaft 1 passes through the lower bevel gear. The outer wall of the rotating block 1 is fixedly connected to the upper bevel gear, and the rotating block 1 passes through the upper bevel gear. The two bevel gears mesh with each other, and the cross groove passes through the rotating block 1. Power is transmitted to the lower bevel gear through the rotating shaft 1.

A cross rod is fixedly connected to the bottom of the second rotating block, and a polishing disc is fixedly connected to the outer wall of the second rotating block. The second rotating block penetrates the second bracket, and the cross rod is adapted to a cross groove. The electric telescopic rod drives the second bracket to lift and lower, so that the cross rod engages or disengages from the cross groove, thereby realizing the lifting and rotation of the polishing disc to adapt to different working needs.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a clamping part, when it is necessary to clamp the tool, the tool can be moved to the three jaws. Then the handle can be turned to drive the lead screw to rotate, thereby driving the triangular slider to slide under the action of the bracket. In turn, the jaws will slide under the action of the limiting groove and the limiting block. When the three jaws come close to each other, the tool will be clamped in the center. This can stably clamp the tool that needs to be polished, prevent the tool from tilting during high-speed grinding, avoid uneven grinding, and thus ensure the quality of the tool.

[0016] 2. By setting up an adjustment unit, when the rotating shaft rotates, it drives the rotating block one to rotate through two bevel gears. Under the action of the cross groove and cross rod, the polishing disc is driven to rotate through the rotating block two, thereby polishing the tool. When it is necessary to adjust the height of the polishing disc, the electric telescopic rod can be activated, which drives the rotating block two to move upward through the bracket two, thereby moving the polishing disc. Under the action of the cross groove and cross rod, the transmission is not affected, and the height of the polishing disc can be adjusted. This allows it to be quickly adjusted to the appropriate position when facing tools of different sizes, without affecting the transmission of the device, thus ensuring processing efficiency.
