Abstract
The utility model discloses a push broach device for processing an inner gear ring. The push broach device comprises a clamping rod, wherein one end of the clamping rod is connected with a guide bar; and the guide bar is provided with cutting edges formed in parallel. In the adopted technical scheme, the guide bar is provided with the cutting edges formed in parallel, so that cutting is quick and chip discharging is smooth in a gear pushing process of a constructed layered structure, the processing work hour can be shortened effectively, the production efficiency is increased, and the efficiency is increased by over 75 percent than the conventional linear cutting method; and processed product inner gears are of stable and consistent shapes and angle sizes, an error is reduced in comparison to an original design, the surface roughness of the inner gears is high, the product quality is enhanced, and the working difficulty of field random detection is lowered. Moreover, processing can be performed only by connecting the clamping rod of the push broach device with more economical and appropriate ordinary punching equipment, and the running cost is reduced greatly. Furthermore, the push broach device has the advantages of simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to the industrial machinery manufacture field, particularly a kind of push broach device that is used to process internal gear.
Background technology
At present, to the processing of internal tooth part, normally adopt the method for line cutting electric machining in the commercial production.This processing method time spent is longer, and production efficiency is lower; And the shape of product internal tooth, angle are bigger compared to former design error, not only have influence on the quality of product, have also increased the follow-up on-the-spot work difficulty that detects examination at random.In addition, use the wire cutting machine of this method to belong to precision equipment, cost is higher, and the devices consume cost is also bigger during operation.Can not satisfy the fast-developing demand of modern mechanical industry.
Summary of the invention
The technical problem that the utility model will solve is: a kind of simple in structure, push broach device that is used to process internal gear that cost is lower is provided, can shortens the processing time spent, enhance productivity, product quality, reduce operating cost, to overcome the deficiency of prior art.
The utility model is achieved in that it comprises supporting rod 1, and an end of supporting rod 1 is connected with gib block 2, on gib block 2, is provided with the cutting edge 3 that is arranged in parallel.
The above-mentioned push broach device that is used for processing internal gear, the length of described cutting edge 3 each cutting edge are tapered from short to long arrangements, and conical lower portion is positioned near supporting rod 1 one sides.
Owing to adopted technique scheme; Compare with prior art; The utility model is provided with the cutting edge that is arranged in parallel on gib block, the hierarchical structure that constitutes like this cuts in pushing away the tooth process fast, chip removal is smooth, can shorten the processing time spent effectively; Enhance productivity, than the synergy of traditional wire cutting method more than 75%; And the shape of the product internal tooth that processes, Angular Dimension stable and consistent, more former design error is less, and the internal tooth surface roughness is better, has improved product quality, has reduced the work difficulty of on-the-spot detection examination at random.In addition, only need the supporting rod of the utility model is connected with comparatively economic suitable common pressing equipment, can process, significantly reduced the cost of operation.Besides, the utlity model has advantage simple in structure, that cost is lower.
Description of drawings:
Fig. 1 is the sketch map of the utility model structure;
Being labeled as of accompanying drawing: 1-supporting rod, 2-gib block, 3-cutting edge.
The specific embodiment:
The embodiment of the utility model: the structure of the utility model is as shown in Figure 1; It comprises existing supporting rod 1 (shape of supporting rod 1, size can basis and the connection requirement of existing commercially available conventional pressing equipment make); One end of supporting rod 1 is connected gib block 2; The cutting edge 3 (cutting edge 3 is made into cutting edge shape, and its length is pressed the internal tooth dimensional requirement and made, the end parts parallel of cutting edge 3 and gib block 2) that is arranged in parallel is set on gib block 2.Supporting rod 1, gib block 2 and cutting edge 3 can adopt existing conventional method to be made into one.For accurate location; And make and push away in the tooth process that cutting is more quick, chip removal is more smooth; Can the length of cutting edge 3 each cutting edge be made into tapered from short to long arrangement, and conical lower portion (being the longest sword of cutting edge 3) is positioned near supporting rod 1 one sides (the longest sword of cutting edge 3 is pressed the internal tooth dimensional requirement and made).
Add man-hour at the part internal tooth, the supporting rod 1 of the utility model is connected with conventional pressing equipment, through the utility model rectilinear motion, 3 pairs of parts of cutting edge cut and feed processing.
