In order to solve the above technical problems, the technical solution adopted in the utility model is as follows:
A kind of fixture for shape extrusion, including being equipped with the pedestal of sliding slot, bottom is slidably matched by sliding block and sliding slot Left and right clamping plate, the pull rod across left and right clamping plate bottom and the Linear scaling part that is connect by cam with pull rod, it is described it is left, Auxiliary pressing element is respectively equipped in the opposite plate face of right clamping plate, auxiliary pressing element includes two pieces and sets along clamping plate length direction and incline backwards Oblique tabletting, tabletting side are hinged with clamping plate, and opposite side is connect by goring push spring with clamping plate.
Preferably, the opposite sheet body of two tablettings of the auxiliary pressing element is equipped with convex ribs, and convex ribs are made of rubber.
Preferably, described pull rod one end be equipped with spacing block set, the other end pass through left and right clamping plate after with cam pin axis connection, The roundlet segmental arc of cam is hinged with the output terminal axis pin of Linear scaling part.
Preferably, resetting spring is arranged on the pull rod between the left and right clamping plate, resetting spring both ends contradict respectively The plate face of left and right clamping plate.
Preferably, the left and right clamping plate both sides are all equipped with auxiliary pressing plate, and auxiliary pressing plate is equipped with through-hole, and outer diameter is less than logical The pin in hole is connect after passing through through-hole with clamping plate, and holddown spring is arranged in the rivet nut between the top cap of pin and auxiliary pressing plate.
Preferably, the holddown spring moment is in confined state.
Preferably, the Linear scaling part is cylinder, hydraulic cylinder or electric cylinder.
The use process of the utility model is as follows:
Between two clamping plate of the workpiece amount of being put into processed being needed first, it should be noted that should be by it when workpiece is placed It is positioned between two tablettings on clamping plate, overcomes the elastic force of goring push spring using the volume of workpiece to strut two tablettings, so press Piece can carry out workpiece auxiliary compression under the elastic force effect of goring push spring, the rubber system convex ribs in tabletting can improve its with Workpiece is pressed into contact with effect;Then by the way that Linear scaling part is controlled to move so that cam is rotated to drive pull rod axial float, So that left and right clamping plate relative movement, clamps workpiece again.Left and right clamping plate and the compression of tabletting are carried out at the same time.
In order to improve clamping effect again, the utility model is also clamped by the way that pressing plate is assisted to provide perpendicular to left and right clamping plate The pressure of force direction:The elastic force of holddown spring is overcome to pull auxiliary pressing plate so that incline the one end of auxiliary pressing plate far from holddown spring Tiltedly and pressure is on workpiece.
The utility model can efficiently clamp the workpiece with faceted pebble or cylindrical type by the principle of multiple spot clamping. After work pieces process, Linear scaling part reset movement, left and right clamping plate is mobile backwards in the effect of resetting spring, then again The elastic force of holddown spring is overcome to pull auxiliary pressing plate, workpiece is taken out.
The utility model compared with prior art, has the following advantages that:The utility model is simple in sturcture, ingenious in design, right Modification of Clamp is convenient in the prior art, can improve processing stability efficiently to being clamped with faceted pebble shape or columnar workpiece.
Description of the drawings
Fig. 1 is for the structure diagram of the fixture of shape extrusion in specific embodiment.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.
As shown in Figure 1, a kind of fixture for shape extrusion, including be equipped with the pedestal 1 of sliding slot 11, bottom by sliding block with Left clamp 2 that sliding slot 11 is slidably matched, right clamping plate 3, across the pull rod 15 of left and right clamping plate bottom and by cam 12 and pull rod The Linear scaling part 14 of 15 connections:15 one end of pull rod be equipped with spacing block set, the other end pass through left and right clamping plate after with 12 axis pin of cam Connection, the roundlet segmental arc of cam 12 are hinged with the output terminal axis pin of Linear scaling part 14, are covered on the pull rod 15 between left and right clamping plate Equipped with resetting spring 13,13 both ends of resetting spring contradict the plate face of left and right clamping plate respectively.
