Slot, places driving key in keyway, the keyway processing of the pull rod, in the past using scribing by bench worker, then in a manner that line is processed, not only
Need scribing process and process keyway when centering non-cutting time, processing efficiency is low, and process after each pull rod keyway size
Uniformity is poor, in order to improve the processing conditions, has developed processing pull rod keyway positioning instrument.
Utility model content
The utility model will solve the keyway processing of existing pull rod using scribing by bench worker, then in a manner that line is processed, need
Want scribing process and process keyway when centering non-cutting time, processing efficiency is low, and process after each pull rod keyway size one
The problem of cause property is poor, and a kind of processing pull rod keyway positioning instrument is provided.
A kind of processing pull rod keyway is made of with positioning instrument clamp body, pressing plate and holding screw；
The clamp body is made of fixture block, first boss and second boss；The working surface of fixture block is from top to bottom successively
Equipped with V-groove, threaded hole and first boss, fixture block lower surface is equipped with second boss；The bottom of the V-groove is fillet, and
The radius of fillet is 5mm；Two working surfaces of the V-groove are set to 90 degrees；
Kidney slot is set below the pressing plate side surface；
Pressing plate fits with first boss side surface, and passes through holding screw and be connected with clamp body.
The beneficial effects of the utility model are：The processing pull rod keyway positioning instrument of the utility model, economic and practical, effect
Fruit is fine, the machining status of design feature and pull rod keyway for pull rod, has developed processing pull rod keyway positioning instrument, profit
During with the tool processes pull rod keyway, pull rod is located in the V-groove of clamp body, not only easy to operate, but also since each part is drawn
Bar is added using the unified processing dimension uniformity for positioning, substantially increasing each part pull rod keyway of V-groove of clamp body by original
Work precision is 0.1mm, is reduced within 0.03mm, due to saving scribing by bench worker and centering process using the tool processes, adds
Work efficiency rate improves more than 50%.

Specific embodiment
Specific embodiment one：Present embodiment is illustrated with reference to Fig. 1-8, present embodiment is a kind of processing pull rod key
Slot positioning instrument is made of clamp body 1, pressing plate 2 and holding screw 3；
The clamp body 1 is made of fixture block 1-1, first boss 1-2 and second boss 1-3；The working surface of fixture block 1-1
V-groove 1-4, threaded hole 1-5 and first boss 1-2 are from top to bottom equipped with successively, and fixture block 1-1 lower surfaces are equipped with second boss 1-3；
The bottom of the V-groove 1-4 is fillet, and the radius of fillet is 5mm；Two working surfaces of the V-groove 1-4 into
90 ° of settings；
Kidney slot 2-1 is set below 2 side surface of pressing plate；
Pressing plate 2 and first boss 1-2 side surfaces fit, and pass through holding screw 3 and be connected with clamp body 1.
Present embodiment second boss 1-3 location and installations are on lathe, location and installation pull rod 4, spiral shell in V-groove 1-4
Pit 1-5 coordinates with holding screw 3, and pull rod 4 is clamped on clamp body 1 using holding screw 3 and pressing plate 2, first boss 1-2
It is used to support pressing plate 2 so that pressing plate 2 can secured compressing pull rod 4；
Present embodiment kidney slot 2-1 is holding screw 3 by hole, using holding screw 3 and pressing plate 2 by pull rod 4
It is clamped on clamp body 1, during using 2 compressing pull rod 4 of pressing plate, 2 upper end compressing pull rod 4 of pressing plate, 2 lower end of pressing plate is supported on first
On boss 1-2.
The advantageous effect of present embodiment is：The processing pull rod keyway positioning instrument of present embodiment, warp
Ji is applicable in, and effect is fine, and the machining status of design feature and pull rod keyway 4-1 for pull rod 4 has developed processing pull rod keyway
4-1 positioning instruments, during using tool processes pull rod keyway 4-1, pull rod 4 is located in the V-groove 1-4 of clamp body 1, not only
It is easy to operate, and since each part pull rod 4 is using the unified positioning of V-groove 1-4 of clamp body 1, substantially increase each part pull rod key
