Abstract

The utility model relates to a novel integrated pressed mud guard and shaft pin tool assembly. The novel integrated pressed mud guard and shaft pin tool assembly comprises a rivet head, an installation base, an upper installation seat and a lower installation seat, wherein a spring-back block is arranged between the upper installation seat and the lower installation seat; the upper installation seat, the lower installation seat and the spring-back block are fixed with one another through fourth screws; the lower installation seat is fixed on the installation base through a third screw; a positioning pin is fixed on one side of the installation seat through a first screw; the rivet head is fixed in the lower installation seat through a second screw. The novel integrated pressed mud guard and shaft pin tool assembly has the beneficial effects that (1) a conventional N1 pressed mud guard tool and a conventional N1 pressed shaft pin tool are improved and combined, so that the cost is reduced, and the production efficiency is improved; (2) the tool assembly is easily installed on equipment, and can be used after being easily fixed on the equipment; (3) the tool assembly has automatic returning and error-proof functions, and phenomena that riveted parts are unlikely to be taken down and are unqualified are avoided;(4) the tool assembly is safe to use, and the one-time pressing size is ensured.

Description

A kind of novel press-fit dashboard and pivot pin one frock assembly

Technical field

The utility model relates in the assembling of front overhang brake products such as a kind of N1/N300 of being widely used in, and that mainly plays the function that press-fits pivot pin and dashboard novelly press-fits dashboard and pivot pin one frock assembly.

Background technology

As shown in Figure 1, this frock is directly to be connected hydraulic press to press down on the contiguous block, and by bolt that upper connecting base 22 and hydraulic press contiguous block 21 is fastening after die resilience piece 24 and upper connecting base 22 are installed, hydraulic press contiguous block 21 is fastening with riveted joint 23.

1, operation principle:

1) knuckle counter-rotating is fixed on down on the frock, with that dashboard of hand dashboard is held up in the precompressed position, the whole frock of primer fluid press is carried out riveting point 25 after moving downward dashboard being pressed onto the position.

2) hydraulic press upwards gos up, and riveting point 25 breaks away from knuckle and riveting point 25 with knuckle by fast 24 elasticity of die resilience.

2, shortcoming:

1) be that what to adopt is the mode of back-pressure dress press-fiting, riveted joint back knuckle usually with riveted joint 23 adhesions, can not easily take off;

2) be two stations separately with frock because press-fiting dashboard and press-fiting pivot pin now, so it is long to press-fit the time, generation problem chance is many;

3) consumption personnel, frock, equipment are many, and the maintenance rate height is inconvenient to keep in repair;

4) no error-disable function in use.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of easy and simple to handle, use high novel of safety, production efficiency to press-fit dashboard and pivot pin one frock assembly.

The purpose of this utility model is finished by following technical solution, and it comprises die, mounting seat, upward mount pad reaches mount pad down, and described going up between mount pad and following mount pad is equipped with the resilience piece, and interfixes by the 4th screw between the three; Described mount pad down is fixed on the mounting seat by the 3rd screw, and a side of this mounting seat fixedly has alignment pin by first screw; Described die is fixed in the following mount pad by second screw.

As preferably, built-in mistake proofing cover, stop collar and the spring that return is used in the middle of the described resilience piece, the following bottom of this mistake proofing cover is embedded in down in the mount pad intracardiac, and the upper end that mistake proofing is overlapped is placed in the lower end of spring.

As preferably, described die is embedded in resilience piece and the last mount pad, and carries out guide pad spacing and guiding, and this guide pad be embedded in mount pad in intracardiac, the lower end ladder block of guide pad is placed in the upper end of spring.

1), the utility model presses dashboard frock, N1 last item pin frock to carry out improving used N1 to merge, reduce cost, enhance productivity the beneficial effects of the utility model are:; 2), be easily mounted on the equipment, only simple and easy being fixed on the equipment of frock can need be used; 3), have the effect that automatically replies and misplace, avoided riveted joint back part to be difficult to take off and the defective situation of part; 4), use safety, it is guaranteed once to press-fit size.

Label in the accompanying drawing is respectively: 1, alignment pin; 2, mounting seat; 3, following mount pad; 4, resilience piece; 5, go up mount pad; 6, stop collar; 7, spring; 8, guide pad; 9, die; 10, mistake proofing cover; 11, first screw; 12, second screw; 13, the 3rd screw; 14, the 4th screw; 15, fender; 16, knuckle; 17, pivot pin; 18, hydraulic press pressure head; 21, hydraulic press contiguous block; 22, upper connecting base; 23, riveted joint; 24, die resilience piece; 25, riveting point.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in accompanying

drawing

2,3, the utility model comprises die 9, mounting seat 2, upward mount pad 5 reaches mount pad 3 down, described upward

mount pad

5 and 3 of following mount pads are equipped with resilience piece 4, and interfix by the 4th screw 14 between the three; Described mount pad 3 down is fixed on the mounting seat 2 by the 3rd screw 13, and a side of this mounting seat 2 fixedly has alignment pin 1 by first screw 11; Described die 9 is fixed in the following mount pad 3 by second screw 12.

Built-in mistake proofing cover 10, stop collar 6 and the spring 7 that return is used in the middle of the described resilience piece 4, the following bottom of this mistake proofing cover 10 is embedded in down in the mount pad 3 intracardiac, and the upper end of mistake proofing cover 10 is placed in the lower end of spring 7.

Described die 9 is embedded in resilience piece 4 and the last mount pad 5, and carry out guide pad 8 spacing and the guiding, and this guide pad 8 be embedded in mount pad 5 in intracardiac, the lower end ladder block of guide pad 8 is placed in the upper end of spring 7.

This novel operation principle that press-fits dashboard and pivot pin one frock assembly is (as shown in Figure 4):

One, the preparatory stage: dashboard 15 is placed in the slit that snaps in guide pad 8 and last mount pad 5 on the frock guarantees that dashboard 15 is stable, put knuckle 16 and put pivot pin 17.

Two, pressing stage: primer fluid press, hydraulic press pressure head 18 knuckle 16 when exerting pressure to pivot pin 17 is firm to be moved downward with guide pad 8, this moment, dashboard 15 was press fit on the knuckle 16 stably, along with continuing to move downward, 9 beginnings of four dies are riveting point (this moment, resilience piece 4 and spring 7 began compression) on knuckle 16, and along with continuing to move downward, last mount pad 5 is with after stop collar 6 in the piece contacts, knuckle 16 and dashboard 15 are fixing, are not moving downward.Pivot pin 17 beginning and knuckle 16 carry out interference fit, overwhelm the position to pivot pin 17.

Three, the return stage: press hydraulic press return button, knuckle 16, pivot pin 17 and dashboard 15 components just move upward under the restoring force effect of spring 7 and resilience piece 4, after resilience piece 4 is returned to original shape, continuation is by spring force move upward (knuckle 16 start from die 9 throw off), only be returned to the home position to guide pad 8, the component that presses is taken off get final product.

This is novel to press-fit dashboard and pivot pin one frock assembly has installation and convenient disassembly, fast efficient, once press-fits and finishes, and is press-fit into place and can be automatically and the characteristics of riveting point disengaging.

The utility model is not limited to above-mentioned embodiment; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model all is a kind of distortion of the present utility model, all should think within the utility model protection domain.
