Abstract
The invention relates to an improved force amplifying lead screw for a four-jaw independent chuck, which can realize reasonable selection of part materials under different working requirements and solve the problem of non ideal hot machining of the overall lead screw, and simultaneously can realize the aim of effectively clamping workpieces under the condition of low torsional moment. The improved force amplifying lead screw for the four-jaw independent chuck comprises a body, and is characterized in that a mandrel is inserted at one end of the body, and the other end of the body is connected with an external hexangular shaft; the external hexangular shaft supports an oblique sleeve; an internal conical surface of the oblique sleeve is pressed on a conical block; a connecting sleeve is pressed on a circular table top of the inner wall of the body; after a screw is in threaded connection with the external hexangular shaft, the end part of the screw is connected with an addendum cone which passes through the conical block; and the conical block is pressed on a spring which is pressed on an internal circular table wall surface of the connecting sleeve.
Description
(1) technical field
The present invention relates to machining frock field, be specially a kind of used reinforcement leading screw of four-jaw chuck of improvement.
(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 invention provides a kind of used reinforcement leading screw of four-jaw chuck of improvement, 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 invention 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.

Fig. 2 is a stereogram of the present invention.
(5) specific embodiment
See Fig. 1, Fig. 2, the present invention includes body 1, an end of body 1 is fitted with push rod 5, and the other end of body 1 is an outer-hexagonal axle 7, outer-hexagonal axle 7 suppresses oblique cover 2, tiltedly the inner conical face of cover 2 press-fits in circular cone 8, and adapter sleeve 12 roof pressures are in the inwall round table surface of body 1, and screw rod 9 is threaded afterwards with outer-hexagonal axle 7 that its end is connected addendum cone 10, addendum cone 10 passes circular cone 8, circular cone 8 press-fits in spring 11, and spring 11 press-fits the interior round platform wall in adapter sleeve 12, and 5 is that push rod, 13 is spring; 6 is that end cap, 3 is that copper nut, 4 is pad.
Claims (1)
