Abstract
An automobile hollow brake disc fast positioning and clamping device comprises a hydraulic clamp disc, three sliders, and clamp claws which are respectively fixed on the three sliders and are provided with support pins, and the improvement is that each clamp claw is fixedly provided with two clamp pins with the heads with conical surfaces; the head of the clamp pin aligns with the centre line of the hydraulic clamp disc; and the centre lines of the six clamp pins are on the same plane. Through the chamfered surface left two outer side disc surfaces of the ventilated rib of the hollow brake disc, six conical surfaces matched with the chamfered surface are served as the clamp point to finish positioning and clamping at a time, and to limit five degrees of freedom of the workpiece, when in clamping, the conical surface is in touch the chamfered surface of the workpiece, so the touch area is greatly reduced, the discordance of the positioning caused by the high point of the positioning surface of the workpiece and the looseness when in machining are avoided, and the machining precision is ensured.
Description
Technical field
The utility model relates to the quick positioning clamping device of the hollow brake disc of a kind of automobile, is applied to the processing of the hollow brake disc part of automotive brake, belongs to the part processing technical field.
Background technology
The most of disk braking system, particularly car of adopting of automotive brake adopts the front and back four-wheel all to adopt disk brake usually at present.And brake disc and wheel rotate synchronously in the disk brake, and automobile brake is that the rotation by the control brake disc realizes car deceleration or parking.As seen, brake disc is one of vehicle key part, and the brake disc part processing is directly connected to running car performance and security performance.
It is the fillet surface realization of blocking the brake disc ventilated rib by three circular arcs that the location of the existing hollow brake disc of automobile clamps, its contact area is big, because blank is more coarse, its ventilated rib fillet surface is smooth inadequately, may deposit several places has high point, when arc surface steps up the ventilated rib fillet surface, if there is high point just in time to be positioned at this contact-making surface, then can cause the brake disc positioning accuracy to descend, can't satisfy high-end vehicle's brake disc processing needs; And the part locating surface is when having high point, can cause locating inconsistent and adds the loosening phenomenon in man-hour, causes to collapse cutter, damage cutter.
Summary of the invention
The purpose of this utility model is: at above the deficiencies in the prior art, the quick positioning clamping device of the hollow brake disc of a kind of automobile is proposed, it utilizes the taper seat at place, pressing pin location, clamp with hollow brake disc workpiece ventilation slot two outside disc surface chamfers location, it is accurate, efficient that this kind part processing is realized.
In order to reach the above object: the utility model provides the hollow brake disc of a kind of automobile quick positioning clamping device, its composition comprises: oild chuck, three slide blocks, be individually fixed on described three slide blocks and have a nail claw, it is characterized in that: the clamped spiked of fixing two head band conical surfaces on each claw, the head of clamped spiked is aimed at the center line of described oild chuck, and the center line of six clamped spiked is positioned at same plane.
And the bus of the clamped spiked head conical surface equates with the chamfer angle of the angle of clamped spiked center line with brake disc ventilated rib fillet surface.
Utilize the course of work of this quick positioning clamping device processing brake disc as follows: under the positioning clamping device releasing orientation, hollow brake disc part to be processed is placed on supporting nails on, adjust the supporting nail and make hollow brake disc ventilation slot center and pressing pin center contour (initial workpiece is adjusted during batch process); Thereafter press the clamping button, six pressing pins (locating pin) are under claw (oild chuck) drives, brake disc workpiece ventilation slot fillet surface is positioned clamping, part processing (cutter moves cutting) is finished in workpiece rotation under oild chuck drives, press release button, the part of processing is finished in taking-up, and once mounting machines.
The fillet surface that the utility model utilizes hollow brake disc part ventilated rib two outside cards to leave, with six taper seats with this fillet surface coupling as clamping point, disposablely finish quick location and clamp, 5 frees degree of workpiece have been limited, the upper and lower bus of taper seat contacts with the workpiece fillet surface during clamping, significantly reduced contact area, avoided causing the location inconsistent and add the loosening phenomenon in man-hour, guaranteed machining accuracy because of the workpiece locating surface has high point.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model releasing orientation structural representation.
Fig. 2 is the utility model clamped condition structural representation.
The specific embodiment
The quick positioning clamping device of the hollow brake disc of the automobile of present embodiment as shown in Figure 1 and Figure 2, the quick positioning clamping device of the hollow brake disc of automobile, its composition comprises: oild chuck 8, three slide blocks 7, be individually fixed on described three slide blocks 7 and claw 6, its improvements of having a nail are: the clamped spiked 2 of fixing two head band conical surfaces on each claw 6, the head of clamped spiked 2 is aimed at the center line (axis) of described oild chuck 8, and the center line of six clamped spiked 2 is positioned at same plane; The bus of the clamped spiked 2 head conical surfaces equates that with the chamfer angle of brake disc 1 ventilated rib fillet surface the angle of the bus of the clamped spiked head conical surface and clamped spiked center line is 45 ° in this example with the angle of clamped spiked 2 center lines.
As shown in Figure 1 and Figure 2, in the present embodiment, clamped spiked 2 by holding screw 3 be fixed on the claw 6, a nail 5 is fixed on the claw by adjusting nut 6, a nail 5 can be realized Height Adjustment by adjusting nut 6.
Utilize the detail operations process of this device processing parts as follows:
(1), hollow brake disc part to be processed is put into supporting nails on this moment pressing pin center and hollow brake disc ventilation slot center contour (needing to adjust the supporting staple height first);
(2), press the clamping button, oild chuck moves to the center under the oil pressure effect, under three slide blocks drove, three claws moved to the center;
(3), two pressing pins that distribute on each claw, entad move with claw, its taper seat contacts the location with hollow brake disc ventilated rib two outside disc surface chamfers;
(4), hollow brake disc rotates synchronously with oild chuck, cutter moves to be finished the workpiece processing action;
(5), after part finishes processing, oild chuck stops operating, and presses release button, oild chuck drives three claws separately under the oil pressure effect, pressing pin unclamps hollow brake disc workpiece, takes off the part after the processing.
So far, a part is located, clamps, is machined.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection domain of the utility model requirement.
