Abstract
A kind of pair of chuck automatic controller, belong to field of machining, the utility model is not have the one side of claw to be provided with ring gear in chuck (4), (6), be installed in the two ends of power transmission shaft (2) with ring gear meshed gears (3), (7), also be fixed with shift fork (1) and worm gear (8) on the power transmission shaft (2), worm gear (8) and worm screw (9) engagement, worm screw (9) links to each other with hydraulic motor.The utility model has the advantages that having solved motor drags the two gripper chuck tense-laxs of the lathe part disadvantage do not opened of pine sometimes that goes into operation, and greatly reduces working strength of workers, convenient during use, safety, reliable simultaneously.
Description
Technical field
The utility model relates to field of machining, particularly a kind of pair of chuck automatic controller.
Background technology
At present, two chuck lathes clamp and unclamp workpiece and divide manually and electronic two kinds, manually clamp with to unclamp the workpiece working strength of workers big, and non-cutting time is long.Electronic clamping with unclamp workpiece because motor rotating output torque equates, also equate with the power of unclamping workpiece so clamp.But because after workpiece clamped, through cutting, temperature can raise, workpiece can expand, and causes the clamping force before the claw processing bigger, and the moment of torsion the when moment of torsion when therefore unclamping workpiece should be greater than clamping work pieces could guarantee the workpiece clamping and unclamps freely.Obviously motor clamps with tripping-gear and does not accomplish to unclamp moment of torsion greater than fastening torque.In addition, motorized clasping mechanism also needs to add overload protecting mechanism, is difficult to realize the in good time adjustment of fastening torque.
Summary of the invention
The purpose of this utility model just provide a kind of safe, reliably, easily by two chuck automatic controllers of fluid motor-driven.
Realize that the utility model purpose solution is to comprise chuck (4), (6) that are installed in the main shaft two ends, it is characterized in that not having the one side of claw to be provided with ring gear in chuck (4), (6), be installed in the two ends of power transmission shaft (2) with ring gear meshed gears (3), (7), also be fixed with shift fork (1) and worm gear (8) on the power transmission shaft (2), worm gear (8) and worm screw (9) engagement, worm screw (9) links to each other with hydraulic motor.
Shift fork (1) is connected with three oil cylinders (10).
The utility model has the advantages that having solved motor drags the two gripper chuck tense-laxs of the lathe part disadvantage do not opened of pine sometimes that goes into operation, and greatly reduces working strength of workers, convenient during use, safety, reliable simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Be separately installed with chuck 4,6 in main shaft 3 both sides, chuck 4,6 does not have the one side of claw to be provided with ring gear, be installed in the two ends of power transmission shaft 2 with ring gear meshed gears 3,7, be fixed with shift fork 1 on the power transmission shaft 2, also be connected with worm gear 8 by slide key on the power transmission shaft 2, worm gear 8 and worm screw 9 engagements, worm screw 9 is driven by hydraulic motor.Shift fork 1 is connected with three oil cylinders 10.
During work, workpiece (bar) is passed spindle hole and passes through chuck 4,6, shift fork 1 shifting shaft 2 moves to a side (as chuck 4 these sides), the gear 3 and the ring gear of chuck 4 are meshed, and at this moment hydraulic motor just drives worm screw 9 rotations, and worm screw 9 drives worm gears 8 rotations, just rotate by slide key axle 2 with worm gear 8, the rotation of axle 2 driven gears 3, the ring gear that gear 3 drives chucks 4 rotates, and just makes claw on the chuck 4 to central motion clamping work pieces (bar).Shift fork 1 shifting shaft 2 moves to opposite side (as chuck 6 these sides) then, the gear 7 and the ring gear of chuck 6 are meshed, at this moment hydraulic motor just drives worm screw 9 rotations, worm screw 9 drives worm gear 8 rotations, just rotate by slide key axle 2 with worm gear 8, the rotation of axle 2 driven gears 7, the ring gear that gear 7 drives chucks 6 rotates, and just makes claw on the chuck 6 to central motion clamping work pieces (bar).After the claw of two chucks 4,6 clamped workpiece, shift fork 1 shifting shaft 2 mediated, and makes the ring gear of gear 3,7 and chuck 4,6 all break away from engagement.Just can start spindle chuck 4,6 this moment and drive the workpiece rotation, the beginning machining.After machining is intact, above-mentioned action is come again, just with the hydraulic motor counter-rotating, just the claw of chuck 4,6 can be unclamped, workpiece just can unload.
Moving of shift fork 1 can be manually, also can be motor-driven.Shown in the drawings is that shift fork 1 is connected with three oil cylinders 10, it is exactly the shift fork 1 that drives by hydraulic jack 10, hydraulic jack 10 has three position left ends, right-hand member and centres, realize shift fork 1 left and right and position intermediate, the i.e. clamping of a side chuck 4 with unclamp, opposite side chuck 6 clamps and unclamps, the gear 3,7 of middle both sides and all out-of-gear position of ring gear of chuck 4,6.
Claims (2)
1, a kind of pair of chuck automatic controller, comprise the chuck (4), (6) that are installed in the main shaft two ends, it is characterized in that not having the one side of claw to be provided with ring gear in chuck (4), (6), be installed in the two ends of power transmission shaft (2) with ring gear meshed gears (3), (7), also be fixed with shift fork (1) and worm gear (8) on the power transmission shaft (2), worm gear (8) and worm screw (9) engagement, worm screw (9) links to each other with hydraulic motor.
2, according to the two automatic clamping and release of the chuck mechanisms of the said lathe of claim 1, it is characterized in that shift fork (1) is connected with three oil cylinders (10).
