Description

Technical Field

[0001] The utility model relates to the technical field related to milling cutters, in particular to a quick disassembly and assembly structure for milling cutters. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the excess of the workpiece intermittently in turn. The milling cutter is mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. In the past, milling cutters were usually fixed with bolts. Due to the need to frequently replace milling cutters, the repeated rotation of the bolts can easily damage the threaded holes. In severe cases, thread stripping may occur. At the same time, when replacing, the screws need to be slowly removed to remove the milling cutter. This process is more troublesome and reduces the efficiency of replacing the milling cutter. Therefore, a quick disassembly and assembly structure for milling cutters has been invented, as shown below.

The quick installation structure for machining milling cutters can freely adjust the distance between the two limit plates through the interaction between the limit plate and the fourth spring, so that the milling cutter body can be clamped and fixed to a certain extent, and the milling cutter body can also be quickly disassembled. Since it can be fixed without screws, the problem of slowly removing the screws to disassemble the milling cutter during replacement is avoided.

When disassembling, it is necessary to use matching special tools to eject multiple positioning pins, which makes the disassembly work time-consuming and labor-intensive, and the efficiency is low. Therefore, its structure needs to be improved and its practicality needs to be improved. Utility Model Content

[0022] The elastic clamping structure includes a spring 10 and an abutment plate 11. The spring 10 is provided with two groups. The two groups of springs 10 are respectively fixedly installed on the inner wall of the two mounting grooves 3 away from each other. The opposite sides of the two abutment plates 11 are respectively fixedly connected with the two groups of springs 10. The sides of the two abutment plates 11 that are close to each other abut the inner walls of the two mounting grooves 3 respectively.
