Abstract

The invention provides a single bond broach clamp for a horizontal broaching machine and can be used for solving the problems that an existing single bond broach is likely to have cutter drop off or cutter hitting phenomena, potential safety hazard is possible to cause due to manual cutter assembling and disassembling, and the working intensity is large. The single bond broach clamp for horizontal broaching machine comprises a columnar clamping head, wherein the left end of the columnar clamping head is in threaded connection with a machine tool; a clamping nut which is adhered to the end face of the machine tool tightly is screwed at the left side of the clamping head; a cutter hole is formed at the center of the right side of the clamping head; a positioning hole which is communicated with the upper and lower end faces of the clamping head and communicated with the cutter hole is formed at the right side of the clamping head; a positioning pin which is clamped inside a cutter clamping groove is inserted inside the positioning hole; and a limiting bolt which penetrates inside the cutter hole is screwed at the lower end of the clamping head at the right side of the positioning hole.. With the single bond broach clamp, the problems of cutter drop off and cutter hitting are overcome; the production efficiency is increased for 3 times; and meanwhile the cutter needs not to be taken off and assembled frequently; and the single bond broach clamp has the advantages of being simple in structure, convenient to operate and low in cost.

Description

Horizontal broaching machine Single bond broach clamp

Technical field

The present invention relates to horizontal broaching machine fixture, be specially a kind of horizontal broaching machine Single bond broach clamp.

Background technology

Existing KEYWAY BROACH many employings collet location, after cutter (i.e. KEYWAY BROACH) broaches and terminate, cutter cannot be fixed at chuck, causes cutter to occur falling cutter phenomenon; And because only have point location during cutter withdrawing, cause withdrawing process cutter to forge a knife; To forge a knife situation for reducing cutter, use existing frock to need after cutter has been broached, cutter to be taken off, part to be processed is contained in after in frock, cutter is loaded onto, labour intensity improves greatly again, and during owing to getting cutter, lathe is still in motion process, there is potential safety hazard.

Summary of the invention

In order to solve existing KEYWAY BROACH, the present invention easily occurs falling that cutter is forged a knife phenomenon and adopt artificial handling cutter to there is potential safety hazard and the larger problem of labour intensity, provide a kind of horizontal broaching machine Single bond broach clamp.

The present invention adopts following technical scheme to realize: horizontal broaching machine Single bond broach clamp, comprise the column chuck that left end is threaded with lathe, the binding nut be close to lathe end face is screwed with on the left of chuck, chuck right center has cutter holes, and on the right side of chuck, have locating hole that is through with its upper and lower end face and that communicate with cutter holes, be inserted with the alignment pin be stuck in cutter draw-in groove in locating hole, and the chuck lower end on the right side of locating hole is screwed with the caging bolt penetrated in cutter holes.

Binding nut plays the effect of fixing and locking clip position, prevents the threaded connection place of process chuck left end and lathe from rotating, cause cutter, chuck, workpiece tool three interfere thus the problem of forging a knife; It is movable that alignment pin can only carry out trace left and right in locating hole, thus while the side-to-side movement of restriction cutter, cutter can be made to float, and cutter can not produce location in process; Cutter is positioned at cutter holes, and the motion of cutter above-below direction is restricted; Rotary stopper bolt is used for regulating cutter to level, and ensures that cutter lower surface and workpiece to be processed upper surface are contour.

When carrying out broaching operation, lathe drives chuck to pull left, and now alignment pin right side and locating hole right side are close to, and continue to pull, and alignment pin left side and cutter draw-in groove left side are close to, and realize the broaching operation of cutter; Reverse operating during withdrawing, utilize alignment pin provide cutter broach and withdrawing time clamping force, thoroughly stop to forge a knife and fall cutter problem, therefore process does not need to get cutter, overcomes existing KEYWAY BROACH and easily occurs falling that cutter is forged a knife phenomenon and adopt artificial handling cutter to there is potential safety hazard and the larger problem of labour intensity.

Reasonable in design of the present invention is reliable, thoroughly overcome and forge a knife and fall cutter problem, therefore process does not need to get cutter, time saving and energy saving while stopping potential safety hazard, and process time shortened to 1 minute by original 3 minutes, improving productivity 3 times, adopt alignment pin location, reach the object of changing product when processing different product by changing alignment pin, cutter frequently need not get dress simultaneously, further simplify operational sequence, there is the advantage that structure is simple, easy to operate and with low cost.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

In figure: 1-chuck, 2-binding nut, 3-cutter holes, 4-locating hole, 5-alignment pin, 6-caging bolt.

Detailed description of the invention

Horizontal broaching machine Single bond broach clamp, comprise the column chuck 1 that left end is threaded with lathe, the binding nut 2 be close to lathe end face is screwed with on the left of chuck 1, chuck 1 right center has cutter holes 3, and on the right side of chuck 1, have locating hole 4 that is through with its upper and lower end face and that communicate with cutter holes 3, be inserted with the alignment pin 5 be stuck in broaching tool draw-in groove in locating hole 4, and chuck 1 lower end on the right side of locating hole 4 is screwed with the caging bolt 6 penetrated in cutter holes 3.

In specific implementation process, alignment pin 5 is made up of U-shaped steel part and the connecting rod be fixed on bottom U-shaped steel part, and U-shaped steel part and connecting rod are structure as a whole, and alignment pin 5 inserts in the draw-in groove of both sides before and after cutter from top to down.
