Abstract

The utility model discloses a broaching tool for a tooth-positioning keyway, which comprises a mandrel, a broaching tool, a tooth-positioning special key block, a pressure plate and a support seat. The mandrel is fixed to the connection frame of a machine tool and the outside of the mandrel is sleeved with a gear. A broaching tool guide groove is arranged on the mandrel. The tooth-positioning special key block arranged inside the broaching tool guide groove is aligned with the center of a gear timing tooth. The pressure plate is fixedly arranged on the upper part of the mandrel tightly presses on the gear. The support seat arranged at the lower part of the mandrel is matched with the broaching tool connected with a driving mechanism arranged on the machine tool. Due to the adoption of the broaching tool, the qualified rate of machined keyways is 99.9 %, so that the qualified rate of products is ensured. Meanwhile, the machining cost is greatly reduced and the machining time is one third of the machining time performed through linear cutting. Therefore, the time of delivery is ensured to be met.

Description

To the alligator groove frock of drawing for sleeping in
Technical field
The utility model relates to a kind of alligator groove is crouched and draws frock, especially relates to a kind ofly being used for gear the alligator groove is crouched and drawing frock, belongs to Gear Processing tool technical field.
Background technology
We know; At present abroad to the keyway on the gear except conventional specification requirement is arranged; Increased the necessary and regularly requirement of tooth central lines of center line of keyway again, and in the face of this requirement, most of processing enterprises accomplish this operation through line cutting; Not only change time-consuming long, and cost is high.
The utility model content
In order to solve deficiency of the prior art, the purpose of the utility model is to provide a kind of processing cost is low, process time the is short alligator groove is crouched to draw frock.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of alligator groove is crouched drawn frock, it is characterized in that, comprises mandrel, broaching tool, to tooth dedicated key piece, pressing plate and bearing; Mandrel is fixed on the connection support of lathe, and its outside is with gear, and also is provided with the broaching tool gathering sill on the mandrel; Described tooth dedicated key piece is installed in the broaching tool gathering sill; And to the center of tooth dedicated key block alignment gear timing tooth, above-mentioned pressing plate then is fixed on the top of mandrel, and it compresses gear; Above-mentioned bearing is arranged on the bottom of mandrel, its be arranged on mandrel top and with lathe on the broaching tool that is connected of driving mechanism cooperate.
The bottom of above-mentioned broaching tool also adds and is lined with certain thickness cushion block.
The beneficial effect of the utility model is: the utility model guarantees the width of keyway through the broaching tool with suitable width; Guarantee the degree of depth of keyway through the certain thickness pad of cushioning; Guarantee the symmetry of keyway through the gap between broaching tool gathering sill and the suitable cutter groove, and the center line through the tooth dedicated key being guaranteed keyway and the central lines of tooth regularly, make that the qualification rate of the keyway that utilizes the utility model processing is 99.9%; Guaranteed the qualification rate of product; Greatly reduce processing cost, and process time be 1/3 of the line cutting processing time, guaranteed delivery date.
Description of drawings:
Fig. 1 is the front view of the utility model one embodiment;
Fig. 2 is the cross sectional view of the utility model one embodiment.
Main Reference numeral implication is among the figure:
1, mandrel 2, gear 3, pressing plate 4, to tooth dedicated key piece
5, connect support 6, bearing 7, broaching tool.
The specific embodiment
Below in conjunction with specific embodiment the utility model is done further description:
Fig. 1 is the front view of the utility model one embodiment; Fig. 2 is the cross sectional view of the utility model one embodiment.
As depicted in figs. 1 and 2: the alligator groove crouched draw frock, comprise mandrel 1, broaching tool 7, to tooth dedicated key piece 4, pressing plate 3 and bearing 6, mandrel 1 is fixed on the connection support 5 of lathe; Its outside is with gear 2, and also is provided with the broaching tool gathering sill on the mandrel 1, described tooth dedicated key piece 4 is installed in the broaching tool gathering sill; And tooth dedicated key piece 4 is aimed at the regularly center of tooth of gear; Above-mentioned pressing plate 3 then is fixed on the top of mandrel 1, and it compresses gear 2, and above-mentioned bearing 6 is arranged on the bottom of mandrel 1; It is arranged on mandrel 1 top and with lathe on the broaching tool that is connected of driving mechanism 7 cooperate, be lined with certain thickness cushion block and can also add in the bottom of broaching tool 7.
The utility model guarantees the width of keyway through the broaching tool 7 with suitable width; Guarantee the degree of depth of keyway through the certain thickness pad of cushioning; Through broaching tool gathering sill and suitable cutter, the symmetry that the groove gap guarantees keyway, and the center line through tooth dedicated key piece 4 being guaranteed keyway and the central lines of tooth regularly.
The course of work of the utility model is:
1, at first on the connection support 5 of lathe, locate and install mandrel 1, and fastening mandrel 1 of while;
2, cogged 2 on mandrel 1, and guarantee on the timing teeth directional of gear 2;
3, pack into to tooth dedicated key piece 4 in the broaching tool gathering sill on mandrel 1, and aim at regularly tooth center;
4, then, load onto pressing plate 3, make it compress gear 2 and location;
5, at last through drive mechanism broaching tool 7 actions of lathe, broach, after the outermost end of broaching tool 7 falls into bearing 6; Lifting broaching tool 7, and turned back to and draw a little, then behind the certain thickness cushion block of the bottom of broaching tool 7 cushioning; Broaching once more; Carry out repeatedly, after broaching for several times, keyway is shaped.
Utilizing the qualification rate of the keyway of the utility model processing is 99.9%, has guaranteed the qualification rate of product, greatly reduces processing cost, and process time be 1/3 of the line cutting processing time, guaranteed delivery date.
The advantage of basic principle of foregoing the utility model and principal character and the utility model; The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
