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
Technical field
The present invention relates to horizontal broaching machine and use anchor clamps, be specially a kind of horizontal broaching machine and use the KEYWAY BROACH anchor clamps.
Background technology
Existing KEYWAY BROACH adopts the collet location more, because after cutter (being KEYWAY BROACH) the broaching end, cutter can't be fixed at chuck, causes cutter the cutter phenomenon to occur falling; And during the cutter withdrawing because have only point location, cause withdrawing process cutter to forge a knife; For reducing the cutter situation of forging a knife, use existing frock after the cutter broaching is accomplished, to take off cutter, after part to be processed is contained on the frock; Load onto cutter, labour intensity improves greatly again, and because when getting cutter; Lathe still is in motion process, has potential safety hazard.
Summary of the invention
The present invention is prone to cutter and forges a knife phenomenon and adopt artificial loading and unloading cutter to have potential safety hazard and the bigger problem of labour intensity in order to solve existing KEYWAY BROACH, provides a kind of horizontal broaching machine to use the KEYWAY BROACH anchor clamps.
The present invention adopts following technical scheme to realize: horizontal broaching machine is used the KEYWAY BROACH anchor clamps; Comprise the column chuck that left end is threaded with lathe; The chuck left side is screwed with the binding nut of being close to the lathe end face, and center, chuck right side has the cutter hole, and the chuck right side has the locating hole that connects and communicate with the cutter hole with its upper and lower end face; Be inserted with the alignment pin that is stuck in the cutter draw-in groove in the locating hole, and the chuck lower end on locating hole right side is screwed with the caging bolt that penetrates in the cutter hole.
Binding nut plays the effect of fixing and locking clip position, prevents that the threaded connection place of process chuck left end and lathe from rotating, thereby causes cutter, chuck, workpiece tool three to interfere the problem of forging a knife; Alignment pin can only carry out about trace movable in locating hole, thereby the side-to-side movement of restriction cutter the time, cutter is floated, and cutter can not produce the location in process; Cutter is positioned at the cutter hole, and the motion of cutter above-below direction is restricted; The rotary stopper bolt is used for regulating cutter to level, and guarantees cutter lower surface and workpiece to be processed upper surface height such as grade.
When broaching operation, lathe drives chuck and spurs left, and this moment, alignment pin right side and locating hole right side were close to, and continued pulling, and alignment pin left side and cutter draw-in groove left side are close to, and realize the broaching operation of cutter; Reverse operating gets final product during withdrawing; Clamping force when utilizing alignment pin that cutter broaching and withdrawing are provided; Thoroughly stopped to forge a knife and fall the cutter problem; Therefore process need not got cutter, has overcome existing KEYWAY BROACH and has been prone to cutter and forges a knife phenomenon and adopt artificial loading and unloading cutter to have potential safety hazard and the bigger problem of labour intensity.
Reasonable in design of the present invention is reliable, thoroughly overcome to forge a knife and fall the cutter problem, so process need not got cutter; Time saving and energy saving when stopping potential safety hazard, shortened to 1 minute by original 3 minutes process time, 3 times of improving productivity; Adopt the alignment pin location simultaneously, when the processing different product, can reach the purpose of changing product through changing alignment pin, cutter need not frequently be got dress; Further simplify operational sequence, had advantage simple in structure, easy to operate and with low cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1-chuck, 2-binding nut, 3-cutter hole, 4-locating hole, 5-alignment pin, 6-caging bolt.
The specific embodiment
Horizontal broaching machine is used the KEYWAY BROACH anchor clamps; Comprise the column chuck 1 that left end is threaded with lathe; Chuck 1 left side is screwed with the binding nut of being close to the lathe end face 2, and center, chuck 1 right side has cutter hole 3, and chuck 1 right side has the locating hole 4 that connects and communicate with cutter hole 3 with its upper and lower end face; Be inserted with the alignment pin 5 that is stuck in the broaching tool draw-in groove in the locating hole 4, and chuck 1 lower end on locating hole 4 right sides is screwed with the caging bolt 6 that penetrates in the cutter hole 3.
In the practical implementation process, alignment pin 5 is to be processed by U shaped steel spare and the connecting rod that is fixed on U shaped steel spare bottom, and U shaped steel spare is structure as a whole with connecting rod, and alignment pin 5 inserts in the draw-in groove of both sides before and after the cutter from top to down.
