Example Embodiment

[0019] Example 1

[0020] See figure 1 with figure 2 As shown, a combined pin milling cutter includes a main shaft 1, a rotating body 3, a cutting edge 6 and a drill bit 9. The main shaft 1 is provided with a slot 2 which is U-shaped, which is convenient for the clamping connection of the transmission device , To avoid sliding during rotation, the upper end of the rotating body 3 is connected with the connecting cylinder 4, the upper end of the connecting cylinder 4 is connected with the connecting nut 5, and the connecting nut 5 is provided with a thread matching one end of the spindle 1 for the connecting nut 5. The rotating body 3 is provided with a cutting and milling edge 6, which is used for cutting and milling of materials, and a chip guide groove 7 is arranged on the rotating body 3. The chip guide grooves 7 are arranged uniformly to lead out the chips of the material , The rotating body 3 is connected with a brush 8. The brush 8 can clean the burrs in the pin milling pr...

[0021] Example 2

[0022] In addition, refer to Figure 1-Figure 3 Based on the above embodiment, one end of the main shaft 1 is provided with a thread, and the thread is matched with the connecting nut 5, so that the main shaft 1 is connected with the connecting nut 5, and the main body of the milling cutter can be freely replaced. The chip guide grooves 7 are provided on both sides of the brush 8. The chip guide grooves 7 are symmetrically distributed, so that the chips in the cutting and milling process of the device can be exported. At the same time, the brush 8 removes the burrs. One end of the rotating body 3 is fixedly connected with the drill bit 9, and a plurality of evenly distributed stoppers are provided on the drill bit 9 10. Make the drill bit 9 and the rotating body 3 firmly connected, a plurality of distributed stoppers 10 can be connected to a plurality of cutting blocks 11, a threaded hole is provided on the stopper 10, and the threaded hole matches the fixing b...

Abstract

The invention discloses a combined type milling cutter. The combined type milling cutter comprises a spindle, a clamping groove, a rotator, a connecting barrel, a connecting unit, a milling edge, scrap guide grooves, a hairbrush, a drilling bit, stoppers, cutting blocks, a fixing bolt, liquid outlets, a channel and branch pipes. The combined type milling cutter has the advantages that one end of the spindle is provided with threads, and the spindle is connected with the rotator through the connecting nut; the rotator is provided with a plurality of the scrap guide grooves uniformly distributed, which can timely guide out material scraps; the rotator is also provided with the hairbrush which can eliminate burrs produced during a milling process to improve the cleanliness of milled surfaces;the drilling bit is provided with a plurality of the stoppers which are connected with a plurality of the high-hardness cutting blocks, which can mill and drill high-hardness materials; the inside ofthe combined type milling cutter is provided with the channel allowing cooling liquid to flow in, which then flow out via the liquid outlets at the tops of the branch pipes to cool down the combinedtype milling cutter and further to avoid excessive wearing.

Description

technical field [0001] The invention relates to a pin milling cutter, in particular to a combined pin milling cutter, which belongs to the technical field of processing equipment. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. Cylindrical milling cutters are used for machining flat surfaces on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter, and are divided into two types: straight teeth and helical teeth according to the tooth shape. According to the number of teeth, there are two kinds of coarse teeth and fine teeth. The helical-toothed coarse-toothed milling cutter has fewer teeth, high tooth strength and large chip space, and is su...
