Abstract

The utility model provides a with broaching frock of parallel keyway of taper hole generating line, including the position sleeve, be equipped with the guiding axle in the inclined hole of position sleeve, through bolted connection between position sleeve and the guiding axle, be equipped with the off-load nut on the screw thread of guiding axle, be equipped with the broach in the guide way of guiding axle, set up the work piece on the guiding axle. The utility model discloses a broaching frock is processed on the broaching machine, with the back on the frock is installed to the work piece, the last generating line of work piece just in time is parallel with the broach guide way, like this the broach once through can process out with the parallel keyway of taper hole, improved greatly with the machining efficiency of the parallel keyway of taper hole generating line, the precision is stable, one-time processing is accomplished on the broaching machine, the cost is reduced.

Description

Broaching tool for key groove parallel to taper hole bus

Technical Field

The utility model belongs to the field of machinery, specifically speaking relate to a broaching frock with parallel keyway of taper hole generating line.

Background

The inner hole key groove is usually machined by a planer, an slotting machine or a broaching machine, the key groove parallel to the taper hole bus is parallel to the taper hole bus, and if no special positioning tool is arranged, the key groove cannot be machined, so that the key groove is always difficult to machine, the tolerance is small, the precision is high, the linear cutting method is adopted in the prior art for machining, the positioning is troublesome, the machining efficiency is low, and the cost is high.

SUMMERY OF THE UTILITY MODEL

The technical scheme of the utility model is realized like this: the broaching tool for the key groove parallel to the taper hole bus comprises a positioning sleeve, wherein a guide shaft is arranged in an inclined hole of the positioning sleeve, the positioning sleeve is connected with the guide shaft through a bolt, an unloading nut is arranged on the thread of the guide shaft, a broach is arranged in a guide groove of the guide shaft, and a workpiece is arranged on the guide shaft.

The utility model has the advantages that: the utility model discloses a broaching frock is processed on the broaching machine, with the back on the frock is installed to the work piece, the last generating line of work piece just in time is parallel with the broach guide way, like this the broach once through can process out with the parallel keyway of taper hole, improved greatly with the machining efficiency of the parallel keyway of taper hole generating line, the precision is stable, one-time processing is accomplished on the broaching machine, the cost is reduced.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic sectional view taken along the line a-a of fig. 1 according to the present invention.

Description of the parts: 1. the device comprises a broach 2, a positioning sleeve 3, a guide shaft 4, an unloading nut 5 and a workpiece.

Detailed Description

For a better understanding and appreciation of the invention, it will be further described in connection with the accompanying drawings: a broaching tool for a key groove parallel to a taper hole bus is characterized in that a positioning sleeve 2 is installed in a positioning hole of a broaching machine, a guide shaft 3 is installed in an inclined hole of the positioning sleeve 2, the positioning sleeve 2 is connected with the guide shaft 3 through a bolt and is provided with a taper pin, an unloading nut 4 is screwed on a thread of the guide shaft 3, a workpiece 5 is placed on the guide shaft 3, a broach 1 is installed in a guide groove of the guide shaft 3, and the key groove parallel to the taper hole bus can be machined.

The guide groove of the guide shaft 3 is vital, the guide sleeve 2 is manufactured firstly, then the guide shaft 3 is installed in the inclined hole of the guide sleeve 2, the guide shaft is fixed through a bolt and matched with a taper pin, then the reference surface on the guide sleeve 2 is aligned in the linear cutting, the depth required to be cut is calculated in advance, and the depth required to be cut is determined when the bus of the guide shaft 3 is overlapped with the cutting wire of the linear cutting.

The working process is as follows:

and (3) assembling the assembly of the positioning sleeve 2 and the guide shaft 3, screwing the unloading nut 4, placing the workpiece 5 on the guide shaft 3, and installing the broach 1 in the guide groove of the guide shaft 3, so that the machining can be carried out. After the machining, the workpiece 5 cannot be detached due to interference deformation, and at this time, the workpiece 5 is ejected by the unloading nut 4, so that the workpiece 5 can be detached.

By using the device, the processing efficiency of the key groove parallel to the taper hole bus is greatly improved, the key groove is processed on the broaching machine at one time, and the cost is reduced.

Claims
