Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 and figure 2 As shown, a broach of the present invention includes a head 1 and a tail 2. From the head 1 to the tail 2, there are neck 3 for connection, transition cone 4, leading part 5 for guiding and finishing cutting Working cutting teeth, the head 1 is used to clamp the broach and transmit power, the transition cone 4 is used to introduce the leading part 5 of the broach into the workpiece, the cutting teeth include inner ring cutting teeth 6 and pawl cutting teeth 7, the inner ring cutting teeth There are 10-20 rows of teeth 6, and 60-100 rows of pawl cutting teeth 7, and the tooth shape size of each row of cutting teeth increases sequentially from the cutting end to the cutting end.

[0015] In this embodiment, the pawl cutting teeth 7 are in the shape of a dovetail, and there are trapezoidal grooves between the dovetail-shaped cutting...

Abstract

The invention discloses a broach, which comprises a head and a tail, wherein a neck for connecting, a transition cone, a guide part for guiding and cutting teeth for finishing cutting operation are sequentially arranged from the head to the tail; the head is used for clamping the broach and transferring power; the transition cone is used for introducing the guide part of the broach into a workpiece; the cutting teeth comprise 10 to 20 rows of inner ring cutting teeth and 60 to 100 rows of pawl cutting teeth; and the tooth size of each row of cutting teeth is sequentially increased from the cut-in end to the cut-out end. The broach is specially used for machining the inner teeth of a ratcheting pre-buried piece of an intelligent clutch, can finish cutting of triangular teeth and trapezoidal teeth at one time, is high in machining efficiency, meets the requirement for precision, greatly improves the economic benefits of enterprises, and enhances the market competitiveness of products.

Description

technical field [0001] The invention relates to a chip cutting tool for machining, in particular to a broach specially used for machining internal teeth of embedded parts of an intelligent gear ratchet ruler. Background technique [0002] At present, using the driving inertia and downhill potential energy of motorcycles to slide is one of the effective fuel-saving methods recognized today. The sliding of the original motorcycle is realized by the driver operating the clutch or shifting into neutral. Frequently operating the clutch for shifting and sliding increases the labor intensity of the driver and disperses the driving energy. And accelerated the wear and tear of engine and shift gear, clutch and transmission system parts. This operation is very cumbersome and wastes the forward inertial force of the motorcycle, so a good fuel-saving effect cannot be obtained. On the other hand, when the motorcycle is gliding, the engine becomes a resistance load, so that the gliding ...
