The specific embodiment
Below be specific embodiment of the present invention and combine accompanying drawing, technical scheme of the present invention is done further to describe, but the present invention is not limited to these embodiment.
As shown in Figure 1, parking brake base seat support 1 of the present invention comprises two identical fins 11, and these two fins 11 are being symmetrical set of the plane of symmetry with a plane, and two fin 11 basic one-tenth are tabular, and its principal plane is parallel with this plane of symmetry.Two fins 11 connect through the roof beam structure between them 12, and roof beam structure 12 two ends are connected the position near fin 11 middle parts.Roof beam structure 12 is tabular basically also, and principal plane mainly plays a part to connect to make two fins 11 be synchronized with the movement perpendicular to the principal plane of two fins 11.Need to prove; Though on structure, parking brake base seat support 1 of the present invention is divided into two fins 11 and a roof beam structure 12; They are actually through die casting or other technology are one-body molded; Be non-removable, help to manufacture the conformability of the mechanical property that strengthens support simultaneously like this.
In order to guarantee the symmetry of structure, roof beam structure 12 self also is " V " shape structure with above-mentioned plane of symmetry symmetry.As shown in Figure 1, for subsequent parts adds convenient location in man-hour, the centre of roof beam structure 12 also is that the position of plane of symmetry process offers two knock holees 13, the parallel and process plane of symmetry of the line of centers of knock hole 13.Hereinafter will talk about the effect of knock hole 13.
As shown in Figure 1; According to parking brake base seat support 1 in actual installation with the situation of other parking brake component assemblys; Need offer five through holes 13 on each fin 11 of this support 1; And the line of centers of each through hole 13 is all perpendicular to the plane of symmetry, and the through hole 13 on two fins 11 is corresponding one by one, and promptly cooresponding two through holes have identical aperture, hole depth and the centerline collineation of the two.These through holes 13 will cooperate with miscellaneous part such as connecting rod, the bearing pin etc. of automobile hand brake, constitute complete parking brake jointly.
In order to reduce material consumption and expendable weight, as shown in Figure 1, in the position that through hole 13 or knock hole 14 are not set, all do indent and handle, promptly only near porose position, stay certain distance to make its thickness of slab with fin 11, elsewhere is all by ironed.
Because the hole of offering on the parking brake base seat support 1 of the present invention is more, and part is the integral die-cast moulding, for guarantee precision holes normally post-production come out, these holes come outbreak out one by one, relatively expend man-hour, influence work efficiency.Therefore, the present invention also protects a kind of driller of processing this parking brake base seat support, and is as shown in Figure 2.
Among Fig. 2, driller of the present invention comprises motor 3, bench board 20, guide pillar 22, guide pillar support 21, cutter, anchor clamps, hydraulic power head 25.
Wherein, all parts all are installed on the bench board 20, and bench board 20 is static relatively.In the middle of the bench board 20 is anchor clamps, the parking brake base seat support 1 of clamps (still undressed go out through hole 13) to be processed in order to clamp on bench board 20.Anchor clamps comprise the positioning fixture 27 that butterfly as shown in Figure 2 is protruding, and the shape complementarity of the female parts of the shape of this butterfly bossing and roof beam structure 12 lower surfaces makes roof beam structure 12 can just be buckled on this butterfly bossing, thereby positions.
Preceding text can know that the centre of roof beam structure 12 is provided with two knock holees 14, and the positioning fixture 27 upper surface correspondence positions here are provided with the locating dowel pin 26 of the identical convexity of quantity.Roof beam structure 12 must make locating dowel pin 26 corresponding with the position of knock hole 14 before being buckled on the positioning fixture 27; Therefore can further improve the particularity of location; Simultaneously mainly be to prevent that when boring, its parking brake base seat support 1 is the front and back sway on positioning fixture 27.
Further; Can know by Fig. 2; The front end of above-mentioned butterfly bossing is provided with two cylinders 23, and the rear end is provided with a cylinder 23, and each cylinder 23 top respectively is connected with a pressing plate 24; Be used for respectively being pressed on the two ends of roof beam structure 12 on the outer end with two fins 11, thereby whole parking brake base seat support 1 is fixed.Cylinder 23 promptly is used for driving corresponding pressing plate 24 and presses down.
Respectively there is a tooling both sides of anchor clamps; As shown in Figure 2; On each fin 11, there are a plurality of through holes 13 to drill through; Corresponding a plurality of milling cutters that are used for holing 28 can be installed on then every cover cutter, require simultaneously each milling cutter 28 must with each fin 11 on will to process the position of through hole corresponding, i.e. axis/the centerline collineation of the two.The application of milling cutter 28 simultaneously also must be satisfied the dimensional characteristic of respective through hole 13.
The outside of every cover cutter is equipped with a hydraulic power head 25, in order to promote or to spur cutter along its axis direction feed or withdrawing, much all can realize this function in the hydraulic efficiency pressure system of the prior art.The rotation of each milling cutter 28 can realize through motor 3 driven gear groups, and realize the rotation in the same way of all milling cutters 28 through gear cluster.
As shown in Figure 2; Between cutter and cooresponding hydraulic power head 25, also be installed with guide pillar support 21; One guide pillar 22 passes hydraulic power head, the guide pillar support in left side, the cutter in left side, the cutter on right side, the guide pillar support on right side and the hydraulic power head on right side in left side successively; And the parallel axes of guide pillar 22 is in the axis of milling cutter, thereby guarantees the axial unanimity of all parts.The setting of guide pillar support 21 and guide pillar 22 helps improving the cutter working accuracy, improves the quality of trestle component.
The driller of installing behind the parking brake base seat support is as shown in Figure 3, and based on the structure design of above-mentioned driller, above-mentioned support will be easy to be mounted and locate, and helps directly carrying out of hole processing.
In sum, parking brake base seat support of the present invention has a plurality of through holes, adopts traditional boring method to be unfavorable for the efficient of part processing, therefore adopts many milling cutters of the present invention method for processing simultaneously, can increase work efficiency greatly; Simultaneously, the frock of multiple-cylinder multi-platen designs on the anchor clamps, can effectively guarantee the location of part, improves machining accuracy, reduces the off-grade amount.
Specific embodiment described herein only is that spirit of the present invention is made casehistory.Person of ordinary skill in the field of the present invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used terms such as parking brake, support, through hole, knock hole, driller morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; It all is contrary with spirit of the present invention being construed to any additional restriction to them.
