Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to an anti-shake milling cutter. Background Art

[0002] Many of the tools used in people's production and life involve parts with turning and grinding. Milling cutter tools are rotating tools with one or more teeth used for milling. When working, each tooth cuts off the excess of the workpiece intermittently in turn. Milling cutters are mainly used for processing planes, steps, grooves, formed surfaces and cutting off workpieces on milling machines.

[0003] At present, most of the existing milling cutters are directly fixed to the motor output end of the milling machine by bolts. Since vibration will be generated during long-term use, the bolt fixing method may cause the milling cutter to move under long-term vibration, thereby affecting the processing accuracy. Therefore, the utility model provides an anti-shake milling cutter to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and an anti-shake milling cutter is proposed. By rotating the knob set in the clamping block, the movable plate can be driven to clamp and fix the No. 1 fixed block fixed in the cutter head, thereby improving the stability of the cutter head and making the cutter head more convenient to disassemble. At the same time, the connecting block that is chiseled and connected with the clamping block can drive the threaded block and the threaded embedding groove to be chiseled and connected by rotating the rotating rod, thereby further improving the fixing effect of the cutter head.

At the same time, the No. 2 fixing block fixed on one side of the clamping block can be engaged and connected with the connecting block, so as to further fix the cutter head.

[0009] Furthermore, the lower end surfaces of the two movable plates are fixedly provided with buffer pads, and the lower end surfaces of the two buffer pads are fixedly provided with strip rubber pads;

[0010] Through the above technical solution, the fixed buffer pad and the rubber pad can improve the clamping effect of the movable plate on the No. 1 fixed block.

[0011] Furthermore, a clamping groove is provided at the midpoint of one side of the clamping block, and the first fixing block is embedded in the clamping groove;

[0012] Through the above technical solution, after the clamping groove is opened on one side of the clamping block, it can be engaged and connected with the No. 1 fixing block fixed in the cutter head to fix the cutter head.

[0013] Furthermore, a threaded block is fixedly provided at one end of the two rotating rods located in the connecting block, and the two threaded blocks are respectively threadedly engaged with the two threaded embedding grooves;

[0015] Furthermore, the second fixing block is embedded in the fixing embedding groove, and the cross embedding block is embedded in the cross embedding groove;

[0016] Through the above technical solution, after the second fixing block is embedded in the fixing embedding groove, the cross embedding block and the cross embedding groove can be embedded and connected, thereby improving the embedding effect of the clamping block and the connecting block.

[0017] Furthermore, an annular rubber pad is provided between the clamping block and the connecting block, and the annular rubber pad is movably sleeved on the outer surface of the second fixing block;

[0018] Through the above technical solution, the annular rubber pad clamped between the clamping block and the connecting block can improve the connection effect between the clamping block and the connecting block and also play a certain shock-absorbing role.

[0019] Furthermore, the two movable plates are respectively engaged and connected with the two fixing grooves;
