Abstract

The utility model relates to a self-grip clip of equally dividing a circuit, composed of a protruding module, a body channel plate, a cushion plate and a fixing bolt. A plurality of channel openings are arranged at two channels in the direction of the radius of the circle on the body channel plate, and channel bottom openings are arranged at the bottom of each channel. Because of the mutual action of the channel type of the body channel plate, the openings between the channels, the openings at the channel bottom and the materials of the body channel plate, the protruding module is fixed tightly in the channel of the channel plate. The cushion plate is connected with the body channel plate through the fixing bolt. The utility model has reasonable and simple structure, has no an outer sleeve, a combined block or a cushion block, completely breaks away from the tightly goring positioning system of an old clip and is an ideal self-grip clip.

Description

Self-grip clip of circumferencial havling

The utility model belongs to the anchor clamps of branch blanking dies such as circumference and spark machined mould.

In the motor manufacturing, the anchor clamps of the spark-erosion machine tool of the blanking die of punching out electric machine rotor punching and processing blanking die all are the important process equipments of motor manufacturing works.At present, the anchor clamps major part of compound press tool and electric machining mould is made up of parts such as overcoat, body, backing plate, convex modules, and body adopts spacer-type or assembled piece type usually.The basic principle of spacer-type and assembled piece type anchor clamps is identical, the two all is directly to hold out against convex module by overcoat with bolt to be assembled on the body, holding out against in the process of bolt, if the center line of bolt center line and convex module has skew, pressure will cause a moment of torsion, cause the distortion of convex module weakest part, and make cushion block or piece produce microdisplacement, the five equilibrium error that finally causes body frid flute profile, the morpheme error, the scale error of bottom land, simultaneously, in the assembling process of convex module and body, the perpendicularity of convex module and body is difficult to adjust, anchor clamps do not reach expected effect, have influenced the workmanship of motor to a great extent.

It is a kind of from clamping the blanking die of circumference five equilibrium and the anchor clamps of electric machining mould that the purpose of this utility model is to provide.

Design principle of the present utility model adopts the elastic interaction of rigid material, and the interactional principle of organic error that links between each eyelet of circumference five equilibrium, rationally selects bulk material for use, is equipped with rational tolerance, reaches from the purpose that clamps.

The utility model is made up of body frid, backing plate, convex module, set bolt.Directly process grooved on the body frid, whole grooved all uses as localization part.The grooved of body frid is selected rational tolerance for use with cooperating of convex module, and each sharp corner of grooved has small sircle hole, in order to the stress of eliminating material, and the convex module of packing into smoothly, the diameter of small sircle hole is determined according to the concrete geomery of grooved; In order to make the body frid that enough elasticity and clamping force be arranged, between each groove of body frid, some openings of bottom land preparation, a part at bottom land along radial direction, another part between two grooves along radial direction, number of openings between two grooves is assigned to determine that opening length is determined by grooved and bulk material by the stress of material, circumference etc.; Opening is type linearly, and end has small sircle hole, and the effect of small sircle hole is to eliminate stress and can plays the effect that elasticity disappears mutually or grow mutually.These anchor clamps need not overcoat, and convex module is packed in the groove of body frid gently, because the interaction result of opening between groove, convex module and body frid are tight fit and are in non-adjustable state, and the body frid links by set bolt and backing plate and be fastening.

Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.

Fig. 1 is structural representation of the present utility model (Figure of abstract).

Fig. 2 is the left view of the utility model Fig. 1.

As shown in Figure 1 and Figure 2, these anchor clamps are for making the electric spark machine tool anchor clamps that the motor blanking die is used.Fig. 1 is a front view, and Fig. 2 is a left side view, by convex module (1), and body frid (2), set bolt (3), backing plate (4), groove is to opening (5).Bottom land opening (6) is formed.Be processed with several grooves on the body frid (2) along the circumference five equilibrium, be shaped on opening (5) between a groove between two grooves, opening between groove (5) has certain-length along body frid (2) radial direction, there is small sircle hole nearly end, the center of circle, every trench bottom is shaped on a bottom land opening (6) along radial direction, bottom land opening (6) has certain-length one end that small sircle hole is arranged, the other end communicates with bottom land, tongue piece (1) is packed in the groove of body template (2), and body frid (2) connects by set bolt (3) and backing plate (4).

This jig Design is reasonable, simple in structure, do not need overcoat, piece or cushion block have saved the navigation system that holds out against of old-fashioned anchor clamps, the fastening groove that relies on fully on the body frid of convex module and body frid fully, opening between groove, the bottom land opening, the clamping force that forms that interacts between the material of body frid realizes, is a kind of desirable self-clamping fixture.

Claims

1, branch self-clamping fixture such as a kind of circumference, it is characterized in that self-clamping fixture is made up of convex module (1), body frid (2), set bolt (3), backing plate (4), convex module (1) is positioned at the groove of body frid (2), and body frid (2) connects by set bolt (3) and backing plate (4).

2, according to branch self-clamping fixtures such as the described circumference of claim 1, it is characterized in that opening (5) between several grooves that certain-length is arranged along radial direction is arranged between last two grooves of body frid (2), the nearly center of circle of opening between groove (5) one end has small sircle hole.

3, according to branch self-clamping fixtures such as the described circumference of claim 1, it is characterized in that body frid (2) goes up every trench bottom and have several along radial direction the bottom land opening (6) of certain-length to be arranged, bottom land opening (6) one ends communicate with bottom land, and the other end has small sircle hole.

4, according to branch self-clamping fixtures such as the described circumference of claim 1, it is characterized in that each the groove sharp corner on the body frid (2) has small sircle hole.
