Description
Technical field
The utility model relates to a kind of positioner, a kind of specifically flexible pin fast-positioning device.
Background technology
The existing fixed alignment pin of traditional plane and two pits positioner also has by slider-crank mechanism realizes flexible alignment pin.Though its structure of fixed alignment pin is simple, not flexible when making installing and locating workpiece and dismounting workpiece, need be lifted certain altitude with workpiece, has so just increased the workload that adds man-hour, has reduced operating efficiency.And traditional realize flexible alignment pin by slider-crank mechanism, though can realize freely stretch of alignment pin, complex structure, part is too many, be inconvenient to process, and also is not easy to assemble moulding, manufacturing process and assemble cost height.
Summary of the invention
In order to solve the defective that exists in the prior art, the purpose of the utility model provides a kind of flexible pin fast-positioning device, and this positioning device structure is simple, easy to operate, laborsaving, and the location fast.
The purpose of the utility model realizes through following technical scheme:
A kind of flexible pin fast-positioning device, it is characterized in that: this device comprises hydraulic motor, axle, cam, push rod, clamp body, shank and spring; Hydraulic motor be arranged on clamp body on the axle be connected, cam is arranged on the axle; The lower end and the cam of push rod are suitable, and stretch out outside the clamp body upper end of push rod, and shank is arranged on the top of push rod; Spring housing is contained on the push rod and between the lower end of clamp body and push rod.
In the utility model, when cam turns to peak, for anti-throw-out lever moves, be provided with at the boss middle position of cam and be used for limiting the groove that push rod moves, groove can make push rod be parked in that position, just can move once more under external force.Said push rod bottom is suitable with the shape of cam; Said cam quantity can be provided with quantity as required, on axle, is provided with two cams in the utility model.Cam is arranged on the axle through key.Hydraulic motor is connected with axle through shaft coupling.
During work, hydraulic motor rotates, and drives axle through shaft coupling and rotates, and the key on the axle is connected axle with cam, and cam and then rotates.Cam rotates, and makes push rod move up and down, and the alignment pin on push rod top stretches out, and inserts in the locating hole of workpiece, arrives peak, realizes the location.After machining, primer fluid pressure motor once more, the cam backhaul is to minimum point, and the push rod band pin and is return, and location work is accomplished.
In the utility model,, when shank is in running order or during dormant state, push rod does not have the effect of external force can not do any action, has guaranteed the stability of shank location;
In the utility model, the track of push rod is being controlled in the rotation of cam, makes two pins be in work and dormant state, and the track of cam can design as required, makes stable drive continuous.
The utility model is simple in structure, and the number of parts of positioner is few, low cost of manufacture.The said alignment pin of the utility model is telescopic, when installing and dismantle workpiece, will not lift by workpiece, has reduced workpiece and has processed non-cutting time, and transmission and easy to operate can be located workpiece fast, improves working (machining) efficiency, and is good in economic efficiency.The utility model is applicable in the workpiece location.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A view among Fig. 1.
The specific embodiment
The described flexible pin fast-positioning device of a kind of the utility model, see Fig. 1: this device comprises hydraulic motor 1, axle 5, cam 8, push rod 9, clamp body 4, shank 6 and spring 7; Hydraulic motor 1 is connected with axle 5 through shaft coupling 2.Axle 5 is arranged on the clamp body 4 through bearing 3.Cam 8 is arranged on the axle 5 through key 10.Cam quantity can be provided with as required, on axle 5, is provided with two cams in the present embodiment.The lower end of push rod 9 and cam 8 shapes are suitable, are provided with at the boss middle position of cam 8 and are used for limiting the groove 81 that push rod 9 moves, and groove 81 can make push rod 9 be parked in that position, just can move once more under external force.Stretch out outside the clamp body 4 upper end of push rod 9, and shank 6 is arranged on the top of push rod 9; Spring 7 is sleeved on the push rod 9 and between the lower end of clamp body 4 and push rod 9.Be provided with in spring 7 lower ends and be used for the hold-down nut 11 of mounting spring.
During work, hydraulic motor 1 rotates, and drives axle 5 through shaft coupling 2 and rotates, and the key 10 on the axle 5 is connected axle with cam 8, and cam 8 is along with axle 5 rotates together.Cam 8 rotates, and makes push rod 9 move up and down, and the alignment pin on push rod 9 promotion tops stretches out, and inserts in the locating hole of workpiece, arrives peak, realizes the location.After machining, the primer fluid pressure motor 1 once more, and cam 8 backhauls are to minimum point, and push rod 9 is being with pin to return under the effect of spring 7, and location work is accomplished.
The utility model is simple in structure, and the number of parts of positioner is few, low cost of manufacture.When installing and dismantle workpiece, will not lift by workpiece, reduced workpiece and processed non-cutting time, transmission and easy to operate can be located workpiece fast, improves working (machining) efficiency, and is good in economic efficiency.
