Abstract

The utility model discloses a positioning device for a shearing machine. The positioning device comprises a left turntable and a right turntable, wherein a rotary shaft is connected between the left turntable and the right turntable; a supporting block is distributed on a shaft body of the rotary shaft; material baffling plates are further arranged at the two ends of the rotary shaft; the inner part of the rotary shaft comprises a compression spring, an extension spring and a rotation shaft; the compression spring is mounted at the lower end of the supporting block; and one end of the extension spring is connected with the tail part of the supporting block, and the other end of the extension spring is connected with the rotation shaft. By adopting the manner, the positioning device for the shearing machine can closely fix raw materials, a material barrel does not slide and the performance is stable.

Description

Positioner for cutter

Technical field

The utility model relates to field of machining, particularly relates to a kind of positioner for cutter.

Background technology

In prior art, what for the barrel fixed mount of cutter, adopt is polished rod, and barrel is enclosed within on polished rod and gets final product.Above-mentioned simple bin to the cylinder material when carrying material strip due to inertia, and fixing defective tightness, easily produce displacement or skid, inadequate to the protection of raw material, easily produces waste product or too much leftover pieces when shearing.

The utility model content

The technical problem that the utility model mainly solves is to provide a kind of positioner for cutter, can raw material closely be fixed, and not there will be barrel to skid, stable performance.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of positioner for cutter is provided, comprise: left-hand rotation dish and right-hand rotation dish, connect a rotating shaft between described left-hand rotation dish and right-hand rotation dish, the axle body of described rotating shaft is distributed with back-up block, described rotating shaft two ends also are provided with striker plate, described rotating shaft inside comprises Compress Spring, extension spring and a rotating shaft, described Compress Spring is arranged on the lower end of back-up block, described extension spring one end connects the afterbody of back-up block, and the other end connects rotating shaft.

In of the present utility model one better enforcement, for convenience of countershaft, operated, on described right-hand rotation dish, one handle is installed, described handle is connected with rotating shaft.

The beneficial effects of the utility model are: the utility model adopts between back-up block and barrel and is closely cooperated, back-up block, under the connection of Compress Spring, extension spring and rotating shaft, can carry out activity adjustment with respect to rotating shaft, is suitable for the barrel of different pore size, easy to operate, stability is strong.

The accompanying drawing explanation

Fig. 1 is the structural representation of the utility model for the positioner of cutter;

Fig. 2 is the cross section structure schematic diagram of rotating shaft.

In accompanying drawing, the mark of each parts is as follows: 1, left-hand rotation dish; 2, right-hand rotation dish; 3, rotating shaft; 4, striker plate; 5, rotating shaft; 20, handle; 30, back-up block; 31, Compress Spring; 32, extension spring.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises: a kind of positioner for cutter, comprise: left-hand rotation dish 1 and right-hand rotation dish 2, connect a rotating shaft 3 between left-hand rotation dish 1 and right-hand rotation dish 2, the axle body of rotating shaft 3 is distributed with back-up block 30, rotating shaft 3 two ends also are provided with striker plate 4, rotating shaft 3 inside comprise Compress Spring 31, extension spring 32 and a rotating shaft 5, Compress Spring 31 is arranged on the lower end of back-up block 30, extension spring 32 1 ends connect the afterbody of back-up block 30, and the other end of extension spring 32 connects rotating shaft 5; Compress Spring 31, extension spring 32 and back-up block 30 be one group and form an independent material jacking mechanism, and above-mentioned material jacking mechanism radially can carry out 360 degree respectively around rotating shaft 5, vertically can segmentation respectively in rotating shaft 3.

Furtherly, one handle 20 is installed on right-hand rotation dish 2, described handle 20 is connected with rotating shaft 5.

The utility model is for the positioner of cutter, its operation principle: hand-held handle 20 is rotated, handle driven rotary axle 5 is rotated, rotating shaft 5 drive extension springs 32 enter in rotating shaft 3 extension spring 32 simultaneously, at this moment rotating shaft 3 is an optical axis, unload the infralevoversion dish, barrel is inserted in rotating shaft 3; Then release handle 20, rotating shaft 5 makes back-up block 30 again stretch out outside rotating shaft 3 under the pulling force of extension spring 32, at this moment 30 pairs of barrel inside of back-up block are tightened, 4 pairs of barrel two ends of striker plate position simultaneously, barrel is only slowly carried under the spool that enters the cutter work top, makes barrel can not rotated separately and slide.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
