Background

The milling clamp for milling machine clamping needs to pay attention to the problems of positioning, clamping and quantity of clamping. The positioning can be solved by the reference surface of the clamp, and the clamping can be solved by increasing the friction coefficient or increasing the torque and the like. When many semi-manufactured goods of convenient processing of needs, because semi-manufactured goods press from both sides tight face and have the deviation, can cause the inhomogeneous phenomenon of many product atress that milling fixture presss from both sides tightly to take place, the semi-manufactured goods clamp force that both can appear is fit for and the not hard up problem of some semi-manufactured goods takes place, at this moment carries out milling process and causes semi-manufactured goods size to beat and size super poor scheduling problem very easily.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned shortcoming and provide a cause not hard up when avoiding milling fixture clamping face size deviation, the location is accurate, efficient movable type milling fixture.

The utility model discloses an aim at and solve its main technical problem and adopt following technical scheme to realize:

the utility model relates to a movable milling fixture, which is characterized in that; the V-shaped plate is sleeved in the middle of the threaded shaft, the spring and the pressing plate are sleeved at the two ends of the threaded shaft respectively, one end of the pressing plate is inserted into the pin shaft B, the other end of the pressing plate is screwed into the nut for connection, the two ends of the pressing plate penetrate into the pressing block respectively and then are inserted into the pin shaft A respectively to penetrate into the cotter for connection, the V-shaped plate is placed on the bottom plate and screwed into the bolt for connection, and the positioning pin arranged on the bottom plate penetrates through the V-shaped plate.

The bottom plate is T-shaped.

The V-shaped plate is provided with a V-shaped groove on the side surface.

The pressing block is trapezoidal, grooves are formed in the pressing block and in the side face of the pressing block respectively, and the pressing block can swing left and right on the pressing plate by taking the pin shaft A as a center.

The middle part of the pressure plate is protruded.

Compared with the prior art, the utility model has obvious beneficial effects; the technical scheme shows that: the V-shaped plate is sleeved in the middle of the threaded shaft, the spring and the pressing plate are sleeved at the two ends of the threaded shaft respectively, one end of the pressing plate is inserted into the pin shaft B, the other end of the pressing plate is screwed into the nut for connection, the two ends of the pressing plate penetrate into the pressing block respectively and then are inserted into the pin shaft A respectively to penetrate into the cotter for connection, the V-shaped plate is placed on the bottom plate and screwed into the bolt for connection, and the positioning pin arranged on the bottom plate penetrates through the V-shaped plate. Put into hollow rivet part in the V font recess that V shaped plate side set up, rotate the nut, the clamp plate at screw thread axle both ends draws close to the V shaped plate respectively, spring compression, the clamp plate drives the briquetting at both ends and draws close to the V shaped plate, the briquetting both ends compress tightly hollow rivet part respectively, there is the deviation when the hollow rivet part clamping surface of briquetting one end, the briquetting uses round pin axle A to swing on the clamp plate as the center, it is even to make the briquetting press from both sides tight hollow rivet part clamping surface atress, prevent that hollow rivet part is not hard up. The size jumping and the size out-of-tolerance of the hollow rivet parts can not be caused, and a plurality of hollow rivet parts are clamped at one time, so that the looseness caused by the size deviation of the clamping surface of the milling clamp can be avoided, the positioning is accurate, and the efficiency is high.

Detailed Description

The following detailed description of the embodiments, structures, features, and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

The utility model relates to a movable milling fixture, which is characterized in that; v-arrangement board 2 cover is in the middle part of threaded shaft 6, and spring 9, clamp plate 7 are sheathe in respectively at threaded shaft 6 both ends, and the round pin axle B5 other end is inserted to one end and is twisted nut 10 and connect, and clamp plate 7 both ends penetrate respectively in briquetting 3 again and insert round pin axle A4 respectively and penetrate the cotter pin and connect, and V-arrangement board 2 is put and is twisted bolted connection on bottom plate 1, and V-arrangement board 2 is passed to locating pin 8 that sets up on bottom plate 1.

The bottom plate 1 is T-shaped.

And a V-shaped groove is formed in the side surface of the V-shaped plate 2.

The pressing block 3 is trapezoidal, the inner part and the side surface of the pressing block are respectively provided with a groove, and the pressing block can swing left and right on the pressing plate 7 by taking the pin shaft A4 as a center.
