Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical scheme is described further.
It as shown in Figure 1, 2, is caliper 9 to be processed, need to process has the circular arc on upper end 9, and the left and right sides is symmetrical
Trunnion 91, and intermediate cylinder holes 94.In order to which three process is combined into a procedure by clamped one time when processing,
A kind of comprehensive fixture is specially designed, the Railway Project point more outstanding of quality problems in first three sequence is combined into a sequence, is added vertical
Manufacture deviation caused by the problem of work center last time clamping is completed, and is avoided because of resetting and multiple clamping.
A kind of synthesis fixture that the caliper accuracy of manufacture can be improved, including pedestal 1, branch earhole positioning seat 2, compressor arm 3, list
Arm rotation auxiliary hold-down cylinder 4, supporting cylinder 5.
The branch earhole positioning seat 2 is symmetrical to be set on pedestal 1, has the first positioning cylinder 21 and diameter smaller
The second positioning cylinder 22, there is positioning surface, it is fixed that second positioning cylinder 22 is located at first on first positioning cylinder 21
On the positioning surface of circle of position column 21,
3 middle part of compressor arm and the rod end for the first hold-down cylinder 31 being mounted on pedestal 1 are rotatablely connected, the downside of rear end
It is provided with the support frame 32 being mounted on pedestal 1, front end is the first compression end 33,
Clamping arm 41 with liftable rotation on the single-arm rotating auxiliary hold-down cylinder 4, the front end of the clamping arm 41
It is downwardly protrude to form third positioning cylinder 42,
The supporting cylinder 5 is horizontally disposed to be installed on bracket 51, and rod end can forward extend out automatic after contact workpiece
Locking is held out against.
It is adapted in hole on the trunnion 91 for the left and right sides that third positioning cylinder 42 can be inserted on caliper 9.
As shown in figure 3, wherein pedestal 1 provides positioning and the connection function of each workpiece, make to coordinate work between component
Make.
Wherein branch earhole positioning seat 2 is formed by two groups, positions caliper two sides branch earhole and end face respectively.Two positioning surfaces are flat
Face degree requires to be less than 0.01mm.Wherein the lower end surface of the trunnion 91 of the left and right sides of caliper 9 is positioned at the first positioning cylinder 21
On the positioning surface of top, while the second positioning cylinder 22 is inserted into the Kong Zhongxiang on the trunnion 91 of the left and right sides of caliper 9 and fits
Match.
Wherein compressor arm 3 belong to main hold-down mechanism, and its rear end is supported on support frame 32, middle part and the first hold-down cylinder
31 rod end rotation connection, rod end pull downward on compressor arm 3, and caliper 9 is compressed downwards downwards, utilized by the first compression end 33
Lever principle increases the stability of clamp system.Simultaneously in view of the error of blank dimension may make the appearance of two points of compressioning by
The situation of power unevenness, the first hold-down cylinder 31 and pressure arm clearance fit, provide certain amount of floating, make to compress point fitting completely.
Wherein single-arm rotating assists hold-down cylinder 4, is made of two groups of hydraulic cylinders, and pre-pressing two sides trunnion 91, makes workpiece respectively
The downside end face of trunnion 91 be bonded completely with the positioning surface of the second positioning cylinder 22, guarantee the position stability of workpiece, propping up
The support rod end work of hydraulic cylinder 5 is supportted in place and after the compression of compressor arm 3, reinstatement state avoids cutter track.
Wherein supporting cylinder 5 are made of two groups of dedicated hydraulic cylinders, and rod end, which protracts, holds out against the rear end face 93 of caliper 9,
The hydraulic cylinder can realize automatic locking after anchor point contact workpiece, keep stress in work pieces process more stable.The hydraulic cylinder is selected
Taiwan joins an an ancient unit of weight equal to 20 or 24 *taels of silver, model RSF-040AL.
Caliper is put on branch earhole positioning seat 2, starting frock clamping controls program, the first step, single-arm rotating auxiliary
Hold-down cylinder 4 executes pre-pressing, is bonded 91 hole end surface of trunnion on caliper completely with branch earhole positioning seat 2.Second step, support
Locking after the support end extension contact workpiece of hydraulic cylinder 5.Third step, compressor arm 3 is rotated in place and workpiece pressing.4th step, it is single
Arm rotation auxiliary hold-down cylinder 4 resets, and avoids cutter track.The processing that trunnion hole end surface in the other side can be achieved on this fixture, hooks pawl end
The processing in face and the processing of cylinder holes, are completed the process by clamped one time, avoid foozle caused by multiple clamping positioning, together
When, it also adequately ensure that geometric tolerance meets the requirements, and further improves the quality stability of product.
Wherein single-arm rotating auxiliary 4 reset position of hold-down cylinder is the position of dotted line, as shown in Figure 3.
Wherein the rotation of compressor arm 3 refers to that, using the rod end of the first hold-down cylinder 31 as the rotation of axis, such rotation mode makes
It must remove after processing is completed very convenient when caliper 9, it is only necessary to which the first hold-down cylinder 31 rises a distance slightly and is
Can, bar 3 can be rotatably compressed at this time, caliper 9 can be taken when the first compression end 33 is left the top of caliper 9
Get off.
Preferably, first compression end 33 is Y shape shape.As shown in Figure 4,5, 6, the first compression end 33 of Y shape shape
It is bigger with the contact surface contact area of 9 upper end of caliper, meanwhile, Y shape shape can get around the circle to be processed of 9 upper end of caliper
Arc will not interfere to process.
Preferably, the bracket 51 is that L shape is installed on pedestal 1, and the supporting cylinder 5 is installed on its vertical plate
On, first hold-down cylinder 31 is installed on the horizontally disposed plate of bracket 51.This mounting means keeps total more compact.
