Abstract
The utility model discloses a novel clamp mechanism of a wheel hub which comprises an inner expansion cylinder clamp, screws and a locating disc. One end of the inner expansion cylinder clamp is in an open mouth structure, and the other end of the inner expansion cylinder clamp is provided with external threads. The open mouth end is connected with the wheel hub. The threaded end is connected with a pitch circle diameter (PCD) locating disc which is connected to a machine tool main shaft. The PCD locating disc is provided with locating holes matched with the positions, the sizes and the number of wheel hub PCD holes. The PCD locating disc is enabled to be correspondingly connected with the wheel hub PCD holes one by one through the inner expansion cylinder clamp. Each locating hole in the PCD locating disc is fixed through four screws to limit the axial movement of the wheel hub. The PCD locating disc is fixed on the machine tool main shaft through a central hole.
Description
Technical field
The utility model belongs to wheel hub processing unit (plant) field, is specifically related to a kind of clamping device of aluminium alloy wheel hub lathe processing.
Background technology
In the machining processes of aluminium wheel hub, adopt Digit Control Machine Tool to carry out turning processing.At present, in lathe scroll chuck clamping, although scroll chuck has the self-centering function, clamping is easy to operate, but can only one-way force applying during every claw clamping, causes the clamp precision of three jaws of clamping wheel hub different, turning is circular during Vehicle Processing, but the complete jaw of Vehicle Processing unclamps that rear wheel hub can become non-circular because chucking power disappears, and its circularity can not satisfy required precision.In addition, because the position of scroll chuck clamping is the outer rim of wheel hub, tool sharpening continues turning operation after needing to change clip position to the clip position again during Vehicle Processing.Like this, wheel hub just produces twice distortion because of two times of clamping, and the closing line that causes processing can't align, and wheel rim is not positive circle, and this will be so that wheel hub can not be by the detection of dynamic balancing and amplitude.
And the scroll chuck long axiality that can occur afterwards service time reduces and the horn mouth phenomenon, directly affects clamping reliability and machining accuracy, thereby affects the turning quality of wheel hub.
Based on the insurmountable problem of above-mentioned clamping technology, in order to ensure wheel hub Vehicle Processing quality, the utility model provides a kind of high-precision Vehicle Processing method of clamping.
Summary of the invention
In order to reduce manufacturing procedure, to enhance productivity and machining accuracy, the utility model is designed a kind of new car processing method of clamping of wheel hub, realizes that accurate to dimension is high, the wheel hub out of roundness is high, beat is beated purpose little, that balance is good.
Advantage of the present utility model and beneficial effect:
1. add and once to reach the maximum range of work man-hour, reduced operation.
2. reduce the deflection that wheel rim causes because of clamping.
Description of drawings
Fig. 2 is the PCD ring;
Fig. 3 is the front view of interior collet chuck,
Fig. 4 is the left view of interior collet chuck.
Among the figure: 1. collet chuck in, 2. screw, 3.PCD positioning disk, 4. flange, 5. locating hole, 6. centre bore, 7. screw hole.
The specific embodiment
Such as accompanying drawing 1, Fig. 2, Fig. 3, shown in Figure 4, the Novel clamping mechanism of described wheel hub, collet chuck 1, screw 2 and PCD positioning disk 3 in comprising.The design of an interior collet chuck 1 matches with wheel hub PCD hole, and the locating hole 5 on the PCD positioning disk 3 is complementary with the PCD hole of wheel hub.Make the one by one corresponding connection of PCD hole of locating hole 5 and wheel hub on the PCD positioning disk 3 by interior collet chuck 1.Interior collet chuck 1 one end are the structure of dehiscing, and an end has external screw thread, and the end of dehiscing connects wheel hub, and the end of thread connects PCD positioning disk 3.During assembling, interior collet chuck 1 dehisces foundry goods to be felt relieved and step up.A collet chuck 1 has screw hole with flange 4 on the flange 4 in described, and described PCD positioning disk 3 is provided with the locating hole 5 that is complementary with clamping wheel hub PCD hole and the screw hole 7 that is complementary with flange 4 screwing holes.Each locating hole 5 is fixed by four screws 2 on the PCD positioning disk 3, reinforces the bonding strength of PCD locating hole 5, limits moving axially of wheel hub.
The Novel clamping mechanism of the utility model wheel hub utilizes the PCD hole on the hub body to position, and need not the circumference of clamping wheel hub, has reduced the distortion that wheel hub causes because of clamping, and the out of roundness of wheel hub is high.This device is simple, and production cost is low.The out of roundness of wheel hub is high, and dynamic balance is good, reduces trembling of automobile when running at high speed so that take advantage of in the driving process drive steadily comfortable.
Claims (2)
1. the Novel clamping mechanism of this wheel hub is characterized in that: collet chuck, screw and PCD positioning disk in comprising, wherein in collet chuck one end be the structure of dehiscing, one end has external screw thread, dehisce to hold to connect wheel hub, the end of thread connects the PCD positioning disk, and the PCD positioning disk is connected in lathe spindle.
2. the Novel clamping mechanism of wheel hub according to claim 1, it is characterized in that, a collet chuck has screw hole with flange in described on the flange, and described PCD positioning disk is provided with the locating hole that is complementary with clamping wheel hub PCD hole and the screw hole that is complementary with flange screwing hole.
