Abstract

The utility model discloses a track surface broach which comprises a broach body (5), and a cutting part (1), a calibration part (2) and a clamping handle part (4) sequentially arranged on the broach body (5) from the end part to the tail part. Positioning chutes (3) are arranged at the left side and the right side of the broach body; composite teeth arranged on the cutting part (1) and the calibration part (2) are formed by plane teeth (7) and chamfered teeth (8); and the clamping handle part (4) is provided with a positioning trough (9) and a broaching end surface (10). The track surface broach has the beneficial effects that the planeness of a workpiece to be processed is high, the size consistency of the workpiece is good, the surface roughness of the workpiece is small, and the chamfer cutting of the workpiece can be completed in the process of broaching, thereby reducing the processing procedures and time, and enhancing the production efficiency of track connecting pieces. The track surface broach has a simple structure, is simple to produce, and can be continuously used when a cutter which is rubbed to be blunt is reground, thereby saving the production cost.

Description

The crawler belt surface broach
Technical field
The utility model relates to a kind of cutter of processing the crawler belt connector, particularly a kind of crawler belt surface broach.
Background technology
At present, the method of processing crawler belt connector inner chamber mainly contains: (1) adopts the shaping slotting tool to carry out slotting processing on slotting machine, but the slotting machining accuracy is low, surface roughness is little, and need just can process a crawler belt connector inner chamber by stroke ground feed repeatedly, production efficiency is low, is not suitable for producing in enormous quantities; (2) adopt vertical knee-type milling machine that the crawler belt connector is carried out Milling Process, because the restriction of crawler belt connector inner cavity size, slotting cutter and milling cutter knife bar coupling part all must be less than inner cavity sizes, and crawler belt connector material is again a cast iron, make that the slotting cutter consume is serious, cause Milling Process to be restricted in the application aspect the processing of crawler belt connector inner chamber; (3) adopt the line cutting special process, though this method is easy to process, processing back workpiece stress is big, working (machining) efficiency is lower, processing cost is high, does not satisfy the economy requirement of modern processing enterprise.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of working (machining) efficiency height, precision height, crawler belt surface broach that surface roughness is little are provided.
The purpose of this utility model is achieved through the following technical solutions: the crawler belt surface broach, it comprises cutting tip, calibrated section and the clamping shank that sets gradually on cutter hub and the cutter hub from the end to the afterbody, and be provided with positioning runner in the cutter hub left and right sides, the composite teeth that is located on cutting tip and the calibrated section is made up of plane teeth and chamfered teeth, and the clamping shank is provided with locating groove and broaching end face.
The between cog of described cutting tip composite teeth has on the composite teeth of rise per tooth and cutting tip and is processed with chip dividing groove.
The utlity model has following advantage:
Utilize the high-precision characteristics of broaching machine, can make the crawler belt connector inner chamber flatness height that processes, dimensional uniformity is good, surface roughness is little, has improved the quality of processing work; The existence of chamfered teeth can be implemented in and finish the chamfering cutting in the broaching process on the composite teeth, has reduced manufacturing procedure and process time; A plurality of crawler belt surface broaches can be installed on broaching machine process simultaneously, improve the production efficiency of crawler belt connector; Simple in structure being easy to of the utility model produced, and can continue behind the cutter blunt to use behind regrinding, saved production cost.
Description of drawings
Fig. 1 the utility model structural front view
Fig. 2 the utility model structure vertical view
Fig. 3 the utility model is along the A-A cross-sectional view
Among the figure, 1-cutting tip, 2-calibrated section, 3-positioning runner, 4-clamping shank, 5-cutter hub, 6-composite teeth, 7-plane teeth, 8-chamfered teeth, 9-locating groove, the 10-end face of broaching.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As Fig. 1, Fig. 2, the crawler belt surface broach, it comprises the cutting tip 1 that sets gradually on cutter hub 5 and the cutter hub 5 from the end to the afterbody, calibrated section 2 and clamping shank 4, and be provided with positioning runner 3 in the cutter hub left and right sides, positioning runner 3 connects the cutter hub of whole crawler belt surface broach, has the very high accuracy of form and position, in the broaching process, play guiding and positioning action to the crawler belt surface broach, the composite teeth 6 that on cutting tip 1 and calibrated section 2, is provided with, clamping shank 4 is provided with locating groove 9 and broaching end face 10, the broaching power that broaching end face 10 bears the broaching machine push rod, realize broaching processing, composite teeth 6 between cog of cutting tip 1 have on the composite teeth 6 of rise per tooth and cutting tip 1 and are processed with chip dividing groove.
As Fig. 3, composite teeth 6 is made up of plane teeth 7 and chamfered teeth 8.
Use of the present utility model is as follows:
1, the crawler belt surface broach is installed in the positioning fixture of special broaching machine and the lubricating oil of annotating, the number of packages that the crawler belt surface broach is installed is decided on what of broaching machine station, many crawler belt surface broaches can be installed simultaneously to the processing of broaching of crawler belt connector;
2, the crawler belt connector is installed and fixed;
3, start broaching machine, the processing of broaching: cut earlier plane teeth 7 cutting labor and materials planar sections, the fillet surplus of chamfered teeth 8 cutting labor and materials by 1 pair of workpiece of cutting tip; Partly calibrate and smoothing by the planar section and the fillet of 2 pairs of labor and materials of calibrated section again, finish broaching processing;
4, after cutter reaches normal cutter blunt standard, unload the crawler belt surface broach lip surface of its whole cutting tip 1 is carried out regrinding, can continue behind the regrinding to use, when cutter had met or exceeded normal cutter life (referring to tool life), cutter should in time be scrapped.
