Abstract

The invention discloses an inward contracting type spring sleeve clamp which comprises a shell body with a cavity. A fixed sleeve is arranged in the cavity of the shell body, a conical surface is arranged at the tail end of the fixed sleeve, an elastic sleeve is arranged in the fixed sleeve, the elastic sleeve comprises a sleeve seat, the sleeve seat is connected with a plurality of elastic sections, guide seats matched with the conical surface are arranged at the tails of the elastic sections, and the sleeve seat of the elastic sleeve is connected with a pull rod. The inward contracting type spring sleeve clamp has the advantages of being reasonable in design, simple in structure, convenient to operate, high in centring precision and reliable in clamping, saving time and labor in the workpiece dismounting process, and being low in labor intensity of an operator, high in production efficiency, low in production cost and convenient to popularize and use.

Description

Internal withdraw type spring spool fixture
Technical field
The invention belongs to Machining Technology field, relate to a kind of fixture, be specifically related to a kind of internal withdraw type spring spool fixture.
Background technology
Workpiece as shown in Figure 1, its end cylindrical and arc surface need turning to machine, add and conventionally use man-hour scroll chuck to add to hold workpiece in turning, but run into workpiece in enormous quantities and need to add man-hour, employing scroll chuck adds while holding part existence dismounting part cost, effort, the problems such as operator's labour intensity is high, and production efficiency is low, and crudy is bad.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of internal withdraw type spring spool fixture is provided, and it is reasonable in design, simple in structure, easy to operate, centering precision is high, steps up reliably, and dismounting workpiece is time saving and energy saving, operator's labour intensity is low, production efficiency is high, and production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of internal withdraw type spring spool fixture, comprise the housing with cavity, it is characterized in that: the cavity inside of described housing is provided with fixed cover, described fixed cover tail end is provided with the conical surface, described fixed cover inside is provided with resilient sleeve, described resilient sleeve comprises receiver, described receiver is connected with multiple elasticity lobes, multiple described elasticity lobe afterbodys are provided with the guide holder matching with the conical surface, and the receiver of described resilient sleeve is connected with pull bar.
Above-mentioned internal withdraw type spring spool fixture, is characterized in that: between described fixed cover and described resilient sleeve, be fixedly connected with by holding screw.
Above-mentioned internal withdraw type spring spool fixture, is characterized in that: the number of described elasticity lobe is at least two.
The present invention compared with prior art has the following advantages:
(1) this internal withdraw type spring spool jig Design is reasonable, simple in structure, and operation is very easy.
(2) this internal withdraw type spring spool fixture adopts resilient sleeve self-centering, thereby its centering precision is high, adopts internal withdraw type resilient sleeve to add clamping of workpieces, steps up very reliable.
(3) this internal withdraw type spring spool fixture dismounting workpiece is time saving and energy saving, and operator's labour intensity is very low, and productivity ratio is very high.
(4) a lot of parts of this internal withdraw type spring spool fixture are all convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

The specific embodiment
A kind of internal withdraw type spring spool fixture as shown in Figures 2 to 6, comprise the housing 1 with cavity 1-1, the cavity 1-1 inside of described housing 1 is provided with fixed cover 2, described fixed cover 2 tail ends are provided with conical surface 2-1, described fixed cover 2 inside are provided with resilient sleeve 3, and described resilient sleeve 3 comprises receiver 3-1, and described receiver 3-1 is connected with multiple elasticity lobe 3-2, the number of described elasticity lobe 3-2 is at least two, preferably 3.Multiple described elasticity lobe 3-2 afterbodys are provided with the guide holder 3-3 matching with conical surface 2-1, and the receiver 3-1 of described resilient sleeve 3 is connected with pull bar 4.
As shown in Figure 2, between described fixed cover 2 and described resilient sleeve 3, be fixedly connected with by holding screw 5, screw connects safe and reliable, cheap.
The course of work of internal withdraw type spring spool fixture of the present invention is: first this internal withdraw type spring spool fixture is fixedly mounted on to lathe operating position, workpiece 6 is placed between multiple described elasticity lobe 3-2, when pull bar 4 is during to left movement, on resilient sleeve 3 with the guide holder 3-3 of taper seat and the conical surface 2-1 relative sliding of fixed cover 2 tail ends, drive multiple elasticity lobe 3-2 inwardly to shrink simultaneously, thereby guide holder 3-3 is realized, the centering of workpiece 6 is stepped up.Otherwise, in the time that pull bar 4 moves right, unclamp workpiece 6.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
