Abstract

The utility model discloses a fast clamping device for an end face cam, which belongs to the technical field of mechanical processing, and is composed of a clamp body, a positioning screw, a rotating handle, an end face cam, a round head clamping screw, a pressure plate and a workpiece; it is characterized in that: The clamp body is inverted T-shaped; the positioning screw is installed in the right mounting hole of the clamp body and passes through the middle hole of the end cam; the end cam is installed on the right side of the clamp body through the positioning screw, and the end face There is a gap fit between the middle hole of the cam and the positioning screw; the rotating handle is installed in the threaded mounting hole on the right side of the end cam; the pressure plate is installed on the support column in the middle of the clamp body and connected by a straight pin; the workpiece It is installed between the left side of the clamp body and the pressure plate; the lower end of the round head clamping screw is spherical and installed on the right side of the pressure plate, and the lower end just abuts on the end cam. The utility model has the advantages of fast, accurate and firm clamping of workpieces, simple structure, safety and reliability, and easy operation.

Description

A kind of edge cam fast fixture

Technical field

The utility model relates to a kind of edge cam fast fixtures, belong to technical field of mechanical processing.

Background technique

In mechanical manufacturing technology, the clamping of workpiece is required it is very high, in pincers worker clamping, usually used flat-nose pliers into Luggage folder, when the milling flat on some small parts or keyway, since Milling Force is smaller and steady, for complicated or irregular Part with flat-nose pliers come clamping with regard to relatively time-consuming and clamping loosely, if parts fixation is insecure, in process be easy The phenomenon that existing part falls off, falls off in case of part, has great threat to the safety of process equipment, even, for behaviour It will also result in injury as personnel.If productivity is lower in this way for part comparison is long and produces in enormous quantities, it is Saving production cost improves productivity effect, therefore to design a kind of edge cam fast fixture very necessary.

Utility model content

To solve the above problems, the purpose of this utility model is precisely in order to solve above-mentioned the deficiencies in the prior art, this is practical Novel is designed to provide a kind of edge cam fast fixture.

To solve the above problems, the utility model is achieved through the following technical solutions：A kind of edge cam quickly presss from both sides Tight device, it is made of clamp body, positioning screw, rotating handle, edge cam, round end pinching screw, pressing plate and workpiece；Its It is characterized in that：The clamp body is inverted T font, and clamp body left side work top is zigzag；The positioning screw installation In the interstitial hole in the right mounting hole of clamp body and across edge cam；The edge cam is installed on by positioning screw The right side of clamp body is clearance fit between edge cam interstitial hole and positioning screw；The rotating handle is installed on end face In threaded mounting hole on the right of cam；The pressing plate lower-left end face is zigzag, is installed on clamp body intermediate support column, Coupled by straight pin；The workpiece is installed between the clamp body left side and pressing plate；The round end pinching screw lower end is It is spherical and be installed on the right of pressing plate, under correct and withstand on edge cam.

The utility model has the beneficial effects that：It is excellent that clamping workpiece is fast, quasi-, jail and structure are simple, safe and reliable, easy to operate etc. Point.

Detailed description of the invention

Fig. 1 is a kind of edge cam fast fixture structural schematic diagram.

Specific embodiment

As shown in Figure 1, a kind of edge cam fast fixture, it be by clamp body 1, positioning screw 2, rotating handle 3, Edge cam 4, round end pinching screw 5, pressing plate 6 and workpiece 7 form；It is characterized in that：The clamp body 1 is inverted T font, folder Specific left side work top is zigzag；The positioning screw 2 is installed in the right mounting hole of clamp body 1 and passes through end face The interstitial hole of cam 4；The edge cam 4 is installed on the right side of clamp body 1,4 interstitial hole of edge cam by positioning screw 2 It is clearance fit between positioning screw 2；The rotating handle 3 is installed in the threaded mounting hole on 4 the right of edge cam；Institute The 6 lower-left end face of pressing plate stated is zigzag, is installed on 1 intermediate support column of clamp body, is coupled by straight pin；The work Part 7 is installed between the clamp body left side and pressing plate；5 lower end of round end pinching screw be it is spherical and be installed on 6 the right of pressing plate, Under correct and withstand on edge cam 4.Rotating handle 3 counterclockwise, edge cam is rotated by a certain angle when work, oblique in cam Under the action of face, pinching screw lower peripheral surface in close contact therewith is moved up, makes pressing plate just by work using lever principle Part clamps.When rotating clockwise handle 3,5 lower peripheral surface of round end pinching screw, 4 inclined-plane of edge cam drop in close contact therewith It is low, and in the case where cutting effect again, right to use pressing plate and workpiece unclamp, and can remove workpiece.

The utility model is disclosed with preferable implementation above, so it is all to take not to limit the utility model With replacement or equivalent transformation technical solution obtained, all fall in the protection scope of the utility model.

Claims
