Abstract

The utility model discloses a fixture for preventing reverse riveting. The fixture comprises a base body. The fixture is characterized in that: an elastic nail is arranged inside the base body; the upper end of the elastic nail passes through a small hole in the upper part of the base body and then is protruded outside the base body; a recess is formed on an upper surface of the base body on each of two sides of the elastic nail; the lower end of the elastic nail is connected to a spring; the lower end of the spring is connected with a fixing screw; and the fixing screw fixes the spring and the lower part of the base body. By adoption of the fixture, the reverse riveting phenomenon is thoroughly avoided, products can spring out of the recesses after being riveted, difficulty in material taking after the products are riveted is avoided, and a riveting speed is improved by 25 percent.

Description

Prevent riveting contrary treatment tool

Technical field

the utility model relates to the electrical contact manufacturing process, and especially riveted joint process prevents the tool that the rivet riveting is anti-.

Background technology

are at electrical contact or touch in the bridge riveted joint process; Because operating personnel's carelessness is put back contact shoe and is caused the silver contact riveting anti-; This phenomenon can cause the anti-contact of riveting to use, if mistake is put into the serious consequence that appliance switch also not conducting can occur or burn.

Summary of the invention

the utility model purpose is: a kind of tool that prevents that the rivet riveting is anti-is provided.

The technical scheme of the utility model is:

A kind of tool that prevents that riveting is anti-comprises matrix, it is characterized in that, at bullet nail of matrix set inside, said bullet nails on holds the aperture that passes matrix top to protrude in the matrix outside, and the matrix upper face on said bullet nail both sides respectively is provided with a heavy nest;

are further, and said bullet nail lower end is connected with top board, and said top board lower end is connected with spring, and said spring lower end is connected with fixed screw, and said fixed screw is connected spring fixing with matrix underpart.

when riveting operation, the groove in the middle of the product just in time holds bullet nail pressed downward down, and when treating that product two ends projection is put in the heavy nest of matrix, product promptly places can rivet operation.Put back like fruit product, just do not have projection to get in the heavy nest, product cannot fixedly be riveted.After riveted joint was accomplished, bullet was followed closely under the effect of spring, can product be ejected in heavy nest, had avoided the difficulty of getting material after the riveted joint.

The utility model has the advantages that:

The utility model makes it compared with prior art owing to adopt technique scheme, and the good effect that has is:

(1) the utility model has thoroughly been stopped the anti-phenomenon of riveting.

(2) the utility model can eject product after riveted joint in heavy nest, avoided the difficulty of getting material after the riveted joint, and riveted joint speed has improved 25%.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1, the utility model prevent the structural representation of the tool that riveting is anti-;

wherein: 1, matrix, 2, heavy nest, 3, the bullet nail, 4, spring, 5, product, 6, fixed screw, 7, top board, 51, the product groove, 52, the product projection.

Embodiment

Embodiment:

As shown in Figure 1:

A kind of tool that prevents that riveting is anti-; Comprise matrix 1, it is characterized in that, at bullet nail 3 of matrix 1 set inside; Said bullet is followed closely the aperture that passes matrix 1 top in 3 upper ends and is protruded in matrix 1 outside, and matrix 1 upper face of following closely 3 both sides at said bullet respectively is provided with a heavy nest 2;

said bullet is followed closely 3 lower ends and is connected with top board 7, and said top board 7 lower ends are connected with spring 4, and said spring 4 lower ends are connected with fixed screw 6, and said fixed screw 6 is connected spring 4 fixing with matrix 1 bottom.

when riveting operation, the groove 51 in the middle of the product 5 just in time holds bullet and follows closely 3 pressed downward, and when treating that product two ends projection 52 is put in the heavy nest 2 of matrix 1, product 5 promptly places can rivet operation.Put back like fruit product 1, just do not have projection 52 to get in the heavy nest 2, product 5 cannot fixedly be riveted.After riveted joint was accomplished, bullet nail 3 can eject product 5 under the effect of spring 4 in heavy nest 2, avoided the difficulty of getting material after the riveted joint.

Claims

1. tool that prevents that riveting is anti-; Comprise matrix (1); It is characterized in that; At a bullet nail of matrix (1) set inside (3), the aperture that matrix top is passed in said bullet nail (3) upper end protrudes in matrix (1) outside, and matrix (1) upper face on said bullet nail (3) both sides respectively is provided with a heavy nest (2).

2. the tool that prevents that riveting is anti-according to claim 1; It is characterized in that; Said bullet nail (3) lower end is connected with top board; Said top board lower end is connected with spring (4), and said spring (4) lower end is connected with fixed screw (6), and said fixed screw (4) is connected spring (4) fixing with matrix (1) bottom.
