Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a roughing and finishing integrated milling cutter. Background Art

[0002] Nowadays, in the process of mechanical processing, machine tools are generally used to process parts. In order to meet the different processing requirements of parts, corresponding milling tools are needed. Milling cutter is one of them. It 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. It is mainly used for processing planes, steps, grooves, forming surfaces and cutting workpieces on milling machines.

[0003] There are many types of milling cutters, such as cylindrical milling cutters, end milling cutters, ball-end milling cutters, flat-end milling cutters and face milling cutters. In the use of face milling cutters, in order to save milling costs, milling blades are generally installed on the milling cutter handle. During the processing, when the milling blade is worn and the accuracy is poor, only the milling blade needs to be replaced. The installation of the milling blade is fastened with screws. During the installation process, the staff replaces the milling blade by disassembling and assembling the screws. When installing the screws, the operator relies on feeling to determine whether the milling blade is installed firmly, which causes the screw to be too tight or too loose during the locking process. When it is too tight, the operator's knob screwdriver is easy to damage the notch at one end of the screw, causing damage to the edge of the notch, and then the screw cannot be driven to rotate by the screwdriver, affecting the disassembly and assembly of the milling blade. When it is too loose, it is easy for the milling blade to detach from the milling cutter or the milling blade is not properly installed when it contacts the workpiece, resulting in greater wear and consumption.

One ends of the two fastening bolts 10 extend into the two thread grooves 8 respectively and match with the two thread grooves 8 respectively, thereby improving the installation stability of the detection block 9. A positioning block 11 is installed on the detection block 9, and the positioning block 11 extends into the positioning groove 7 and matches with the positioning groove 7. The positioning groove 7 and the positioning block 11 are both T-shaped, which provides better protection for the positioning of the detection block 9. The measuring cylinder 13 is slidably installed on the detection block 9, and one end of the measuring cylinder 13 extends to one side of the detection block 9. Part of the bolt assembly 5 extends into the measuring cylinder 13 and matches with the measuring cylinder 13.

[0024] like Figure 5-Figure 6 As shown, a moving cavity 12 is provided on the detection block 9, and through grooves 1 are provided on the inner walls on both sides of the moving cavity 12, and the two through grooves 1 are coaxial with the threaded hole 13. A measuring cylinder 13 is slidably installed in the moving cavity 12, and the measuring cylinder 13 is arranged in a T-shaped cylindrical shape. Four rectangular sliders are installed on the outer wall of one end of the measuring cylinder 13, and four sliding grooves are provided on the inner wall of the moving cavity 12. The four sliding grooves are slidably connected with four sliders respectively, and a reset spring 14 is sleeved on the measuring cylinder 13 to push the measuring cylinder 13 to return to its original state.

[0025] like Figure 5-Figure 7 As shown, a convex ring 15 is installed on the outer wall of the detection block 9 away from the milling cutter 4.
