Abstract
The utility model relates to a force increasing screw rod of a four-jaw independent chuck, which can realize the reasonable choice of part material under different job requirements, solve the problem that the heat process of the screw rod is not ideal and realize that workpieces are clamped efficiently in lower torque at the same time. The force increasing screw rod comprises a body and is characterized in that a mandril is inserted at one end of the body, and the other end of the body is connected with an outer hexagon shaft which props and presses an inclined sleeve, and the inner conical surface of the inclined sleeve presses a conical block; a connecting sleeve props and presses at a round table surface of the inner wall of the body; the end part of a threaded rod is connected with an addendum cone after the threaded rod is screwed to the outer hexagon shaft; the addendum cone passes through the conical block which presses a spring; the spring presses an inner round table wall of the connecting sleeve.
Description
(1) technical field
The utility model relates to machining frock field, is specially the used reinforcement leading screw of four-jaw chuck.
(2) background technology
Its square body that is used to transmit moment of torsion of the used reinforcement leading screw of existing four-jaw chuck all combines with the threaded portion that is connected with claw.Though it is simple in structure, be convenient to produce, but the heat treatment requirements difference of different parts, cause the part bulk material properties not good, easy to wear, and during holding workpiece, because the moment of torsion transmission is for being rigidly connected, there is the problem that is difficult for clamping work pieces, need to use afterburning long spanner, bring barbarous clamping, cause the problem of part corrupted.
(3) summary of the invention
At existing on the low side, the unfavorable situation of material hot-working of whole leading screw moment of torsion transmission efficiency, the utility model provides a kind of four-jaw chuck used reinforcement leading screw, it can realize the choose reasonable of part material under the different operating requirement, solve the unfavorable problem of whole leading screw hot-working, can be implemented in the effective clamping work pieces under the low moment of torsion simultaneously.
It is realized by following scheme: it comprises body, it is characterized in that: an end of described body is fitted with push rod, the other end of described body connects the outer-hexagonal axle, described outer-hexagonal axle suppresses oblique cover, the inner conical face of described oblique cover press-fits in circular cone, the adapter sleeve roof pressure is in the inwall round table surface of described body, screw rod is connected its end, back and connects addendum cone with the outer-hexagonal male thread, described addendum cone passes described circular cone, described circular cone press-fits in spring, and described pressure mounting of the spring is in the interior round platform wall of adapter sleeve.
Said structure of the present utility model adopts combined type, the structures such as outer-hexagonal axle of screw rod that cooperates with claw and transmission moment of torsion are processed respectively as single component, realize that different operating requires the choose reasonable of part material down, solve the unfavorable problem of whole leading screw hot-working, the inner reinforcement structure that increases, utilize the tiltedly boosting function of cover, circular cone, be implemented in the effective clamping work pieces under the low moment of torsion.
