Description
Technical field
The present invention relates to auto parts and components processing technique field, and in particular to a kind of brake shoe processing fixing device.
Background technology
Auto parts and components as auto industry basis, be support auto industry sustainable and healthy development necessary factor.It is special
It is not vigorous current automotive industry, development like a raging fire independent development and innovation, with greater need for one powerful zero
Part system is supported.Vehicle independent brand needs parts to make basis with technological innovation, and the autonomous innovation of parts is again to whole
The development of car industry produces powerful motive force, and they influence each other, interact, and do not have the independent brand of vehicle, powerful
The innovation ability of parts system is difficult to burst out, the support for not having powerful parts system, independent brand to do your writing strong
Will be hard to carry on.
Brake shoe refers to the actuating quantity by brake cam or push rod and is pushed to and outer launch compacting brake and heave braking action
Accessory, be installed on brake rim, be one of crucial breaking piece in brake system of car.Brake shoe shape such as semilune,
The semi-moon shaped brake shoe of two panels is just outer in the presence of wheel cylinder when touching on the brake, and props up brake shoe and rubs the interior of brake rim
Wall come play a part of slow down or stop.
In the prior art process this brake shoe when more than using sucker fix by the way of, but sucker fixation brake shoe carry out
When brake shoe fixes hole machined, often shake, so as to cause fixing hole mismachining tolerance to increase, so as to have impact on brake shoe
Crudy.
The content of the invention
The invention is intended to provide a kind of brake shoe processing fixing device, to improve the crudy of brake shoe.
In base case：Brake shoe processing fixing device, including frame, have been sequentially arranged folder from top to bottom in frame
The push rod of tight arm, tooth bar, button, spring, gear, eccentric wheel, pivot and driving tooth bar；Wherein frame right side is provided with blind hole,
Button is slided and is arranged in blind hole, and spring is arranged between blind via bottom and button, and clamp arm bottom is provided with through hole, eccentric wheel position
In through hole, eccentric wheel is bonded and is connected on pivot and is articulated in frame by pivot, the center of rotation and eccentric wheel of eccentric wheel
Geometric center it is misaligned, clamp arm middle part offseted with button, gear is bonded and is connected on pivot and is articulated in frame by pivot
On, wheel and rack offsets, and frame right side is provided with the groove slided up and down for tooth bar.
Push rod is by air cylinder driven.When using, workpiece is placed in frame, then controls air cylinder driven push rod to move upwards,
Tooth bar is moved up therewith, wheel and rack engagement, gear counter-clockwise swing therewith, so as to drive pivot counter-clockwise swing, pivot
Axle band movable eccentric wheel counter-clockwise swing, due to clamp arm under spring load by button against workpiece, now eccentric wheel is counterclockwise
Swing and drive the downward workpiece pressing of clamp arm.
After machining, control air cylinder driven push rod is moved down, and tooth bar is moved down therewith, and gear is put clockwise therewith
It is dynamic, so that drive clockwise to swing, so as to drive clamp arm to unclamp workpiece upwards.
The present invention can realize being fixedly secured the quick of brake shoe, substantially increase efficiency, improve the processing of brake shoe
Quality.
Preferred scheme one, based on scheme further optimization, the groove be dovetail groove；Tooth bar makees machine along dovetail groove
During tool relative motion, kinematic accuracy is high, stabilization.
Preferred scheme two, preferably one further optimization, push rod head passes through thread connection with tooth bar lower end；
Facilitate installing/dismounting.
Preferred scheme three, preferably two further optimization, eccentric wheel include be bonded be connected on pivot in cylinder
The rotation section of shape and the eccentric part being wholely set with rotation section, eccentric part are located in through hole；Convenient processing and material-saving.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Specific embodiment
Below by specific embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Tooth bar 10, push rod 11, button 20, gear 12, spring 21, clamp arm
30th, eccentric wheel 31.
Embodiment is substantially as shown in Figure 1：Brake shoe processing fixing device, including frame, in frame from top to bottom according to
It is secondary to be disposed with clamp arm 30, tooth bar 10, button 20, spring 21, gear 12, eccentric wheel 31, pivot and push rod 11；Wherein frame
Right side is provided with blind hole, and button 20 is slided and is arranged in blind hole, and spring 21 is arranged between blind via bottom and button 20, clamp arm 30
Bottom is provided with through hole, and eccentric wheel 31 is located in through hole, and eccentric wheel 31 is bonded and is connected on pivot and is articulated in frame by pivot,
The center of rotation of eccentric wheel 31 is misaligned with the geometric center of eccentric wheel 31, and the middle part of clamp arm 30 offsets with button 20, gear 12
It is bonded and is connected on pivot and is articulated in frame by pivot, gear 12 offsets with tooth bar 10, frame right side is provided with for tooth bar 10
The groove for sliding up and down, the groove is dovetail groove, and the head of push rod 11 is with the lower end of tooth bar 10 by thread connection, the top of clamp arm 30
In hook-shaped setting.
Eccentric wheel 31 includes being bonded the tubular rotation section being connected on pivot and the bias being wholely set with rotation section
Portion, eccentric part is located in through hole.
Pivot two ends are fixed in frame by bearing.
When using, workpiece is placed in frame, then controls the motion upwards of air cylinder driven push rod 11, tooth bar 10 is upward therewith
Mobile, gear 12 is engaged with tooth bar 10, the counter-clockwise swing therewith of gear 12, so that pivot counter-clockwise swing is driven, pivot drive
The counter-clockwise swing of eccentric wheel 31, due to clamp arm 30 under the load of spring 21 by button 20 against workpiece, now eccentric wheel 31 is inverse
Hour hands swing and drive the downward workpiece pressing of clamp arm 30.
After machining, control air cylinder driven push rod 11 is moved down, and tooth bar 10 is moved down therewith, and gear 12 is suitable therewith
Hour hands swing, so that drive clockwise to swing, so as to drive clamp arm 30 to unclamp workpiece upwards.
