Abstract
The utility model discloses an eccentric automobile fixture of an extending shell cover, and the eccentric automobile fixture comprises a fixture body, a first platen device, a second platen device and two elastic eccentric locating devices, wherein the first platen device and the second platen device are successively arranged on the central axis of the fixture body along the longitudinal direction; and the two elastic eccentric locating devices are symmetrically arranged on the fixture body along the central axis of the fixture body and can rotate clockwise or anticlockwise along the circumferential direction. Each elastic eccentric locating device of the eccentric automobile fixture comprises an elastic locating sleeve, a spring, a rotary screw and an eccentric tensioning pin. A longitudinal screw hole is a stair-like screw hole. The eccentric automobile fixture of the extending shell cover has a simple structure, is convenient to operate and is convenient to manufacture, and the clamping precision satisfies the product precision requirement. By utilizing the eccentric tensioning action, the product is firmly clamped and is evenly stressed, the problems of product chatter marks and deformation are eliminated after processing, the lathing processing precision is improved, and the quality loss is reduced.
Description
Technical field
The utility model relates to a kind of extensional shell and covers eccentric vehicle clamper, belongs to the Vehicle Processing field of automobile gearbox extensional shell lid.
Background technology
Automobile gearbox extensional shell cover piece is little, wall thin, shape is unique, is employed in suspended wall place increase supplemental support during Vehicle Processing face operation usually and processes, and chatter mark and distortion appear in machined surface easily after the Vehicle Processing, cannot say for sure to demonstrate,prove the detail drawing requirement.
Summary of the invention
The purpose of the utility model is: in order to improve the Vehicle Processing precision; Reduce the defective work loss; Provide a kind of simple in structure, easy to operate, make the product clamping firm, stressed evenly, the extensional shell that can effectively eliminate product chatter mark and distortion after the processing covers eccentric vehicle clamper.
The technical scheme of the utility model is: comprise frock body, first presser device, second presser device, two eccentric positioners of elasticity; First presser device, second presser device longitudinally are set in turn on the axis of frock body, the eccentric positioner of two elasticity be symmetricly set on the frock body with the axis of frock body and can along circumferential clockwise or be rotated counterclockwise.
The eccentric positioner of the said elasticity of the utility model comprises: elastic locating sleeve, spring, rotary screw, eccentric tensioner pin; Elastic locating sleeve vertically offers in order to vertical screw of eccentric tensioner pin to be set; Eccentric tensioner pin one end is an eccentric end, and the other end is the spiral shell head, and the middle part is threaded with vertical screw and matches; Spring is arranged in vertical screw and is placed on the spiral shell head, and the eccentric end place of eccentric tensioner pin is horizontally arranged with in order to the horizontal screw of rotary screw to be set.
The said vertical screw of the utility model is stepped screw.
The utility model is simple in structure, and is easy to operate, simple for production, and clamping precision satisfies the product required precision;
Utilize eccentric tensioner effect, make the product clamping firm, stressed evenly, eliminated the problem of product chatter mark and distortion after the processing, improved the Vehicle Processing precision, reduced mass loss.

Fig. 2 is the utility model A-A echelon sectional view.
Fig. 3 is the eccentric positioning device structure sketch map of the utility model elasticity.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The utility model comprises frock body 1, first presser device 2, second presser device 3, two eccentric positioners 4 of elasticity.First presser device 2, second presser device 3 longitudinally are set in turn on the axis of frock body 1, two eccentric positioners 4 of elasticity be symmetricly set on the frock body 1 with the axis of frock body 1 and can along circumferential clockwise or be rotated counterclockwise.
The eccentric positioner 4 of elasticity comprises: elastic locating sleeve 5, spring 6, rotary screw 7, eccentric tensioner pin 8.Elastic locating sleeve 5 vertically offers in order to stepped vertical screw 9 that eccentric tensioner pin 8 and diameter do not wait to be set, and eccentric tensioner pin 8 one ends are eccentric end, and the other end is a spiral shell head 10, and the middle part is threaded with stepped screw 9 and matches.Spring 6 is arranged in vertical screw 9 and is placed on the spiral shell head 10.The eccentric end place of eccentric tensioner pin 8 is horizontally arranged with in order to the horizontal screw 11 of rotary screw 7 to be set.
When utilizing the utility model with blank precast hole and hole end surface positioning and clamping product; After compressing first, second presser device; Any direction rotates rotary screw, makes eccentric tensioner pin eccentric excircle tensioner blank precasting hole wall, thereby plays the effect that clamps the product suspending wall part.
