A kind of wheel radial location device
The present invention relates to a kind of positioner, specifically a kind of wheel radial location device.
In the process of automotive wheel, often need be positive as axial and radial location benchmark with wheel, wheel rim or wheel rim position are carried out the measurement of axiality.Owing to be streamline production, so will guarantee the quick-clamping of wheel; Simultaneously must adapt to the wheel that varies in size, so require the stroke of anchor clamps should be enough greatly, stroke have increased the manufacture difficulty of anchor clamps undoubtedly greatly accordingly.High, the low precision of traditional big stroke pneumatic chuck cost, in the wheel alignment application field poor operability, be not suitable for the different wheel type of various moulding, and inefficiency.
Summary of the invention
The objective of the invention is to provide a kind of wheel radial location device, it can adapt to the quick-clamping location of various different wheel types.
To achieve these goals, technical scheme of the present invention is: a kind of wheel radial location device, form by base, bearing, disk, slide, master jaw, jacking block, spring, apical axis, cylinder, end face locating piece, flat key and top.Be uniformly distributed with three slides and three end face locating pieces on the disk, cylinder is connected on the base through bearing, and disk is fixed on the cylinder, and slide and end face locating piece are installed on the disk, and apical axis is a guiding to be installed in slide two inboard flat keys, through spring reset.The top is fixed on the take-off lever end of cylinder, and master jaw is installed in an end of apical axis, and jacking block directly inserts in its locating hole.
Earlier the wheel face down is lain on the end face locating piece during actual the use, realized the end face location; Cylinder promotes to come directly towards and moves upward then, promotes the outwards motion synchronously of three apical axis, and this moment, three jacking blocks can clamp wheel with the mode trailing wheel lip inboard of three-point fix, the realization radial location.Realize the rotation of wheel then with setting stick motor-car wheel or disk.Change wheel greatly for the wheel molded dimension, can be through regulating the stroke that the position of jacking block on master jaw reduces apical axis.
The present invention in use can satisfy the quick-clamping location of all size and variform wheel, have simultaneously stroke little, simple in structure, be convenient to that processing and fabricating, stable performance, positioning accuracy can meet the demands, the characteristics of low cost of manufacture.

Among the figure, 1-base, 2-bearing, 3-disk, 4-slide, 5-master jaw, 6-jacking block, 7-spring, 8-apical axis, 9-top, 10-end face locating piece, 11-cylinder, 12-flat key.
The specific embodiment
Below in conjunction with details and the working condition of description of drawings according to the concrete device of the present invention's proposition.
This device is by base 1, bearing 2, disk 3, slide 4, master jaw 5, jacking block 6, spring 7, apical axis 8, cylinder 11, end face locating piece 10, flat key 12 and come directly towards 9 and form; Cylinder 11 is connected on the base 1 through bearing 2; Disk 3 is fixed on the cylinder 11; Slide 4 is installed on the disk 3 with end face locating piece 10, and apical axis 8 is a guiding with the flat key 12 that is installed in 4 liang of inboards of slide, resets through spring 7; Top 9 is fixed on the take-off lever end of cylinder 11, and master jaw 5 is installed in an end of apical axis 8, and jacking block 6 directly inserts in its locating hole.
In the course of the work, earlier the wheel face down is lain on the end face locating piece 10, realized the end face location; Cylinder 11 promotion tops 9 move upward then, promote three apical axis 8 outwards motion synchronously, and three jacking blocks 6 can clamp wheel with the mode trailing wheel lip inboard of three-point fix at this moment, realize radial location.Change wheel greatly for the wheel molded dimension, can be through regulating the stroke that the position of jacking block 6 on master jaw 5 reduces apical axis 8.
