Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bench centering device used in an automobile final inspection process.

In the final inspection process of a car, for example, when toe measurement is carried out, the car is mounted on the stand of the measuring device, but in this case it is difficult to align the center of the car with the center of the machine stand. The measurement is performed without aligning the centers, which has the disadvantage that the measurement cannot be performed accurately. The present invention has been made to improve such inconveniences, and provides a device that allows the center of the vehicle body of a vehicle mounted on the machine base to easily align with the center of the machine base at the front and rear of the vehicle body. There is something to do.

To explain this with reference to the illustrated embodiment, reference numeral 1 indicates a machine base, and a front center drive unit 2 consisting of a cylinder in the front and back direction is attached to the front frame 1a of the machine base 1 at the center of the lower part thereof. Attach the shaft 3 in the direction, and attach the front arm 4 fixed to the lower end of the shaft 3 to the front center drive part 2.
Rolls 9, 9 for mounting a front wheel are connected to a slider supported by a piston rod 5 via a turnbuckle 7, and a front swinging arm 8 fixed to the upper end of the shaft 3 is provided on the machine base 1. Roller 1 that extends upward and presses the outside of the tire on its tip
0 is set.

Further, the rear frame 1b of the machine base 1 has a horizontal shaft 11 horizontal to the machine base 1, and a vertical lifting cylinder 14 having a piston rod 13 connected to one end of the horizontal shaft 11 via an arm 12. A support plate 15 is attached to the upper surface of the horizontal shaft 11, and a rear center drive section 16 consisting of an opening/closing cylinder is attached to the center of the plate 15, and a rear swing arm 17 is pivotally supported on both left and right sides. The arm 17
is moved up and down by the rotation of the horizontal shaft 11, and a fixed plate 18 protruding from the base thereof is connected to the piston rod 20 of the rear central drive section via an intermediate plate 19 pivotally supported by the support plate 15. In addition, the arm 17 is formed into a bending arm 17a that is bent up and down at its intermediate portion, and has a guide roller 21 that contacts the lower surface of the floor at its tip and a floor side panel. A contact piece 23 consisting of an attachment 22 that contacts the protrusion is provided.

Next, the operation will be explained. When a car is mounted on the machine platform 1, the cylinder 2 is activated and pulls the slider 6, thereby moving the front arm 4 and the shaft 3.
The front swinging arm 8 retracts toward the center of the machine frame through the mechanism and presses both sides of the front wheels inward to align the center of the front of the vehicle body with the center of the machine frame 1. At the same time, the lift cylinder 14 By operating the horizontal shaft 11 and rotating the horizontal shaft 11, the rear swing arm 17, which is pivotally supported by the support plate 15 of the shaft 11, is raised, and the guide roller 21 at the tip thereof is brought into contact with the lower surface of the floor, and then the rear swing arm 17 is rotated. By operating the center drive unit 16 and expanding the rear swing arm 17 outward via the intermediate plate 19, the attachment 22 at the tip comes into contact with the left and right protrusions of the floor side panel, thereby moving the center of the rear of the vehicle body. It is also made to coincide with the center of the machine base 1. In this way, according to the present invention, the front part of the machine base 1 having the rolls 9, 9 on which the wheels of the automobile are mounted is located below the center line of the machine base 1 and is movable forward and backward. A front center drive section 2, a pair of left and right front swing arms 8, 8 connected to the tips of the front center drive section 2 via a pair of left and right turnbuckles 7, and a front swing arm. Rollers 10, 10 which are pivotally supported at the tips of the arms 8, 8 and contact the outer surfaces of the front wheels of the automobile are provided, and rollers 10, 10 are provided at the rear of the machine base 1, parallel to the rolls 9, 9 of the machine base 1. A movable horizontal shaft 11 is provided, and a rear center drive section 16 is provided on the horizontal shaft 11 that can move forward and backward in the front and back direction via a support plate 15. A pair of left and right rear swinging arms 17, 17 are provided which are connected to each other, and at the tips of the rear swinging arms 17, 17, a guide roller 21 that contacts the lower surface of the floor panel of the vehicle and a left and right convex portion of the floor panel of the vehicle are provided. Since the attachment 22 is provided in pressure contact with the base, the vehicle on the machine platform 1 can be moved through the pair of left and right front wheels and the pair of left and right protrusions on the floor side panel at the rear of the vehicle. Since the centering is performed accurately, the front swinging arm can freely adjust its swinging angle to facilitate the work, and the front swinging arm and rear swinging arm can be easily adjusted. Since the arm is located below the vehicle body, centering work can be performed without interfering with other work.
