Description
Technical field
This utility model relates to auto parts and components processing technique field, is specifically related to the fixing device of a kind of brake shoe processing.
Background technology
Auto parts and components, as the basis of auto industry, are the necessary factors supporting auto industry sustainable and healthy development.Particularly the current automotive industry independent development carried out vigorous, like a raging fire and innovation, supports with greater need for a powerful parts system.Car load independent brand and technological innovation need parts to make basis, the development of vehicle industry is produced powerful motive force again by the autonomous innovation of parts, they influence each other, interact, there is no the independent brand of car load, the innovation ability of powerful parts system is difficult to burst out, there is no the support of powerful parts system, independent brand to be your writing good general hard to carry on.
Brake shoe refers to that the actuating quantity by brake cam or push rod is pushed to outer expansion compacting brake and heaves the accessory of braking action, is installed on brake rim, is one of breaking piece of key in brake system of car.Brake shoe shape such as semilune, the semi-moon shaped brake shoe of two panels just under the effect of wheel cylinder outer when touching on the brake, props up the rub inwall of brake rim of brake shoe and plays the effect slowed down or stop.
The mode that in prior art, many employings sucker is fixing when processing this brake shoe, but the fixing brake shoe of sucker carries out brake shoe fixing hole and adds man-hour, often shakes, thus causing that fixing hole mismachining tolerance increases, thus have impact on the crudy of brake shoe.
Utility model content
This utility model is intended to provide a kind of brake shoe processing with fixing device, to improve the crudy of brake shoe.
In base case: brake shoe processing is with fixing device, including frame, frame is sequentially arranged clamp arm, tooth bar, button, spring, gear, eccentric, pivot from top to bottom and drives the push rod of tooth bar；Wherein have blind hole on the right side of frame, button slides and is arranged in blind hole, spring is arranged between blind via bottom and button, clamp arm bottom has through hole, eccentric is arranged in through hole, eccentric key is connected on pivot and is articulated in frame by pivot, eccentric center of rotation is misaligned with eccentric geometric center, offset with button in the middle part of clamp arm, gear key is connected on pivot and is articulated in frame by pivot, wheel and rack offsets, and has the groove slided up and down for tooth bar on the right side of frame.
Push rod is by air cylinder driven.During use, workpiece is placed in frame, then control air cylinder driven push rod to move upward, tooth bar moves up therewith, and wheel and rack engages, and gear is counter-clockwise swing therewith, thus driving pivot counter-clockwise swing, pivot band movable eccentric wheel counter-clockwise swing, due to clamp arm under spring load by button against workpiece, now eccentric counter-clockwise swing drive clamp arm be pressed downward against clamping of workpieces.
After machining, controlling air cylinder driven push rod and move down, tooth bar moves down therewith, and gear is clockwise oscillation therewith, thus driving clockwise to swing, thus driving clamp arm upwards to unclamp workpiece.
This utility model is capable of quickly fixedly securing brake shoe, substantially increases efficiency, improves the crudy of brake shoe.
Preferred version one, based on the further optimization of scheme, this groove is dovetail groove；Tooth bar along dovetail groove make mechanical relative motion time, kinematic accuracy is high, stable.
Preferred version two, the preferably further optimization of one, thread connection is passed through in push rod head and tooth bar lower end；Facilitate installing/dismounting.
Preferred version three, the preferably further optimization of two, eccentric includes the tubular rotation section that key is connected on pivot and the eccentric part being wholely set with rotation section, and eccentric part is arranged in through hole；Conveniently process and save material.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: tooth bar 10, push rod 11, button 20, gear 12, spring 21, clamp arm 30, eccentric 31.
Embodiment is substantially as shown in Figure 1: brake shoe processing, with fixing device, including frame, frame has been sequentially arranged clamp arm 30, tooth bar 10, button 20, spring 21, gear 12, eccentric 31, pivot and push rod 11 from top to bottom；Wherein have blind hole on the right side of frame, button 20 slides and is arranged in blind hole, spring 21 is arranged between blind via bottom and button 20, clamp arm 30 bottom has through hole, eccentric 31 is arranged in through hole, eccentric 31 key is connected on pivot and is articulated in frame by pivot, the center of rotation of eccentric 31 is misaligned with the geometric center of eccentric 31, offset with button 20 in the middle part of clamp arm 30, gear 12 key is connected on pivot and is articulated in frame by pivot, gear 12 and tooth bar 10 offset, the groove slided up and down for tooth bar 10 is had on the right side of frame, this groove is dovetail groove, thread connection is passed through in push rod 11 head and tooth bar 10 lower end, clamp arm 30 top is hook-shaped setting.
Eccentric 31 includes the tubular rotation section that key is connected on pivot and the eccentric part being wholely set with rotation section, and eccentric part is arranged in through hole.
Pivot two ends are fixed in frame by bearing.
During use, workpiece is placed in frame, then control air cylinder driven push rod 11 to move upward, tooth bar 10 moves up therewith, and gear 12 engages with tooth bar 10, gear 12 counter-clockwise swing therewith, thus driving pivot counter-clockwise swing, pivot band movable eccentric wheel 31 counter-clockwise swing, due to clamp arm 30 under spring 21 load by button 20 against workpiece, now eccentric 31 counter-clockwise swing drive clamp arm 30 be pressed downward against clamping of workpieces.
After machining, controlling air cylinder driven push rod 11 and move down, tooth bar 10 moves down therewith, gear 12 clockwise oscillation therewith, thus driving clockwise to swing, thus driving clamp arm 30 upwards to unclamp workpiece.
