Abstract
The utility model discloses a pin drawing mechanism for machining a locating hole. The pin drawing mechanism comprises a locating pin, a locating pin bush, a locating pin seat and an oil cylinder, wherein the locating pin bush is mounted in the locating pin bush; the locating pin bush is mounted in the locating pin seat; the locating pin bush is connected with a piston rod of the oil cylinder by a connecting rod; the lower end of the connecting rod is fixedly connected with the piston rod; the upper end of the connecting rod is movably connected with the locating pin bush; the locating pin is connected with the locating pin bush by a limiting screw; a limiting groove matched with the limiting screw is formed in the locating pin; and a spring is arranged between the locating pin and the connecting rod. When the pin drawing mechanism performs machining, the locating pin can be drawn out the locating hole to machine the locating hole, the machining procedures can be reduced, the efficiency is improved, and the cost is saved more effectively.
Description
Technical field
The utility model relates to mach detent mechanism, especially a kind of pumping pin mechanism while processing locating hole.
Background technology
At present in machining processes, for adopting alignment pin locating hole to be positioned to the workpiece of processing, existing fixing dowel mechanism is processing after other machined surfaces, in the time that needs are processed locating hole, workpiece need to be unclamped, machining hole is shifted out to the alignment pin workpiece that is fixedly clamped again outward, then process locating hole.Need to repeatedly unclamp clamping work pieces like this, machining processes is many, and efficiency is low.
Utility model content
The purpose of this utility model is to provide and is a kind ofly adding the processing locating hole pumping pin mechanism that alignment pin can be extracted out to locating hole man-hour.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of locating hole pumping pin mechanism that processes, comprise alignment pin, set pin sleeve, location key seat and oil cylinder, set pin sleeve is contained in set pin sleeve, set pin sleeve is arranged in location key seat, set pin sleeve is connected by connecting rod with the piston rod of oil cylinder, connecting rod lower end is fixedly connected with piston rod, connecting rod upper end is flexibly connected with set pin sleeve, alignment pin is connected with set pin sleeve by stop screw, on alignment pin, be provided with and the stopper slot that limits screw fit, between alignment pin and connecting rod, be provided with spring.
Preferably, on set pin sleeve, be provided with stroke limit groove, be provided with stroke limit screw on location key seat, the trip stop screw stretches in stroke limit groove, in the situation that oil cylinder stroke is satisfied, the length of the stroke limit groove by set pin sleeve limits the stroke of alignment pin.
Preferably, described alignment pin top be shaped as taper, alignment pin can closely cooperate with the locating hole of workpiece like this, realizes workpiece is accurately located.
The utility model adopts after said structure, has the following advantages:
(1) adding man-hour alignment pin can take away in advance, to reach processing locating hole.
(2) use pumping pin structure, can reduce machining processes, raise the efficiency, more effective cost-saving.
(3) pumping pin flexible structure is stable, can select the cylinder (oil cylinder) of different strokes to better meet actual demand according to different pumping pin required distances.
(4) pumping pin structure goes for any machining processes that need to locate with hole that has.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
In figure: 1 alignment pin, 11 stopper slots, 2 set pin sleeves, 21 stroke limit grooves, 3 location key seats, 4 oil cylinders, 5 connecting rods, 6 stop screws, 7 springs, 8 stroke limit screws.
The specific embodiment
Shown in Fig. 1, the pumping pin mechanism of processing locating hole of the present utility model, comprise alignment pin 1, set pin sleeve 2, location key seat 3 and oil cylinder 4, set pin sleeve 2 is contained in set pin sleeve 2, set pin sleeve 2 is arranged in location key seat 3, set pin sleeve 2 is through location key seat 3, set pin sleeve 2 is connected by connecting rod 5 with the piston rod 41 of oil cylinder 4, connecting rod 5 lower ends are fixedly connected with piston rod 41, connecting rod 5 upper ends are flexibly connected with set pin sleeve 2, alignment pin 1 is connected with set pin sleeve 2 by stop screw 6, on alignment pin 1, be provided with and the stopper slot 11 that limits screw 6 and coordinate, between alignment pin 1 and connecting rod 5, be provided with spring 7.On set pin sleeve 2, be provided with stroke limit groove 21, be provided with stroke limit screw 8 on location key seat 3, the trip stop screw 8 stretches in stroke limit groove 21.Described alignment pin 1 top be shaped as taper, the tapering of alignment pin 1 can closely cooperate with the locating hole of workpiece like this, realizes workpiece is accurately located.
Set pin sleeve 2 is with oil cylinder 4 to be rigidly connected, and alignment pin 1 is connected with set pin sleeve 2 elasticity with form of springs and uses stop screw 6 spacing in addition.Entangle set pin sleeve 2 conducts with location key seat 3 and lead, there is higher quality of fit.When use: reset condition, the piston rod 41 of oil cylinder 4 is for pushing away forward to the greatest extent.Starting switch after installation product, the piston rod 41 of oil cylinder 4 drives set pin sleeve 2 toward pulling back, and drive alignment pin 1 together toward pulling back, thereby alignment pin 1 can exit locating hole completely, and reach the object that can process this locating hole.Due to the effect of spring 7, make alignment pin 1 have certain fine adjustment with respect to set pin sleeve 2, this distance of floating fine setting is the length of the stopper slot 11 of alignment pin 1.
The oil cylinder 4 of the utility model pumping pin mechanism also can replace with cylinder.This pumping pin mechanism is applicable to any machining processes that need to locate with hole that has.
