Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a vehicle body support stand that floats the vehicle body above the floor and fixes it immovably when the vehicle body is being repaired.

``Prior art'' Conventionally, when repairing a car body that has been deformed due to a collision, etc., the car body is generally lifted to the ground using a lift and fixed so that it cannot be moved. The four lower edges are clamped and fixed by clamps provided on a plurality of supports that slide within a pair of rails laid parallel on the floor.

``Problems to be Solved by the Invention'' However, such conventional support stands have columns installed vertically on the bottom plate that slides within the rails, and the upper ends of the columns are placed in a horizontal plane and in a direction perpendicular to the rails. It consisted of a fixed arm member and a clamping device for clamping the lower edge of the vehicle body attached to the arm member. However, the lift that lifts the entire car body cannot always maintain a horizontal state, and on the other hand, the height of each support stand, especially the clamping tools, is constant and cannot be expanded or contracted vertically. It was difficult to clamp the side edges, and since the clamping tool was fixed almost parallel to the rail and could not rotate in a horizontal plane to change its orientation, When the car body was dented and deformed, there was a problem that the lower edge was not parallel to the rail and the clamping tool could not clamp it firmly.

Therefore, the purpose of this invention is to allow the height of the clamping tool to be easily adjusted by rotating the screw shaft, and to allow the mounting tool to be oriented freely in the horizontal plane according to the deformation of the side edge of the vehicle. The purpose of the present invention is to provide a vehicle body support base that can be turned and adjusted.

``Means for Solving the Problems'' The vehicle body support stand of the present invention has a column erected on a bottom plate that slides in a groove in a rail laid on the floor, and an arm member attached to the upper end of the column. The arm member is supported so as to be movable forward and backward in a horizontal plane and in a direction perpendicular to the rail, and furthermore, a female screw hole is vertically provided in one end of the arm member, and a screw shaft is screwed into the female screw hole so as to be able to move up and down. This device has a structure in which a clamping device for clamping the lower edge of the vehicle body is attached to the upper end of the screw shaft so as to be rotatable in a horizontal plane.

"Function" A female screw hole is vertically passed through one end of the arm member, and the height position can be freely adjusted according to the vehicle height by raising and lowering a screw shaft that is screwed into the female screw hole. Then, by rotating the clamping tool in a horizontal plane, the direction can be freely changed according to the deformation of the side edge of the vehicle body, and the clamping tool can be easily clamped and firmly fixed.

``Embodiment'' In the figure, reference numeral 1 denotes a vehicle body support stand of the present invention, two of which are placed on each of a pair of parallel rails 2, 2 laid on a floor surface. Each vehicle body support stand 1
supports an arm member 4 so as to be movable in a horizontal plane and in a direction perpendicular to the rail at the upper end of a support column 3 that is slidably movable in a state in which it is erected within the rail 2, and one end of the arm member 4 A jacking member 5 is attached to the jacking member 5 so that it can be raised and lowered, and a clamping tool 6 that clamps the lower edge of the vehicle body is rotatably supported on the upper end of the jacking member 5 in a horizontal plane.

At the lower end of the support column 3, a cross section is provided on the rail 2.
A bottom plate 8 is fixed to be loosely inserted into the groove 7 of the shape, and a plurality of bolts 9 are passed through the bottom plate 8 to the bottom surface, and by tightening these bolts 9, the top surface of the bottom plate 8 is connected to the bottom surface of the top of the groove 7. The position of the support column 3 is fixed by bringing it into contact with the support column 3. Further, cylinders 10, 10 are fixed to both side edges of the upper end of the support column 3 horizontally and at right angles to the rail 2, so that the pair of support rods 4', 4' of the arm member 4 are fixed in a horizontal plane and at right angles to the rail 2. Each cylinder 10, 10
Tightening bolts 11, 11 are passed through the side wall surfaces of the arm member 4, and the position of the arm member 4 is fixed by tightening the tightening bolts 11, 11.

The jack member 5 is constructed by fixing a receiving plate 12 to one end of the arm member 4, vertically penetrating a female threaded hole 13 through the center of the receiving plate 12, and screwing a screw shaft 14 so as to be able to move up and down. , a small diameter portion 5 is provided around the upper protruding portion of the screw shaft 14, leaving a head portion 14a.

The clamping tool 6 has a vertical plate 17 established in the longitudinal direction of the upper surface of a rectangular base plate 16, and a pair of clamping pieces 18, 18 are fastened to both ends of the vertical plate 17 with tightening bolts 19, 19, respectively. Furthermore, a short cylinder 20 is fixed to the center of the lower surface of the substrate 16, and screw holes 21 are formed through the short cylinder 20 so as to face each other on the side wall of the short cylinder 20. ,22
is screwed through. Then, the short cylindrical body 20 is attached to the head 14a at the upper end of the screw shaft 14, and the thumbscrew 2
2 and 22 are tightened and engaged with the small diameter portion 15 to prevent it from coming off, and by loosening the thumb screws 22 and 22, the direction of the clamping tool 6 in the horizontal plane can be freely adjusted.

FIG. 4 shows how the vehicle body support stand 1 constructed in this manner is used. First, the vehicle body B is driven along a pair of rails 2, 2 laid parallel to the floor surface, and the lift 23 disposed between the rails 2, 2 is raised to lift the vehicle body B to the position shown by the chain line.

Two car body support stands 1 are arranged along the left and right side edges of the car body B, and are used to support the lower edge of the car body B at four places on the front, back, left and right sides. The bottom plate 8 is loosely fitted into the groove 7 of the rail 2 and slid, and the bolts 9 are tightened and fixed at the front, rear, left, and right positions of the vehicle body B, respectively, and the tightening bolts 11 are loosened to cause the arm members 4 to protrude outward, respectively. , Tighten the tightening bolt 11 with the screw shaft 14 screwed through the female threaded hole 13 of the receiving plate 12 positioned at the lower edge of the vehicle body B. Next, raise and lower the screw shaft 14 to determine the height position of the clamping tool 6, loosen the wing screw 22 to align the orientation of the clamping tool 6 in the horizontal plane with the lower edge of the vehicle body B, and adjust the clamping piece 18. , 18, tighten the tightening bolt 19, and further tighten the wing screws 22, 22 to fix the jack member 5.

It should be noted that the arm member 4 is made to protrude outward in accordance with the width of the vehicle, but this was decided from the viewpoint of ease of use in various vehicle bodies of different widths, from light vehicles to large vehicles. When used in a wide vehicle body such as a large vehicle, the auxiliary strut 24 may be made parallel to the strut 3 and stand upright on the lower surface of the receiving plate 12, as shown by the chain line in FIG. In this case, it can sufficiently withstand the load of the car and can be used safely.

"Effects of the Invention" As stated above, the height of the vehicle body support stand of the present invention can be freely adjusted by raising and lowering the screw shaft threaded through the female screw hole provided in the receiving plate of the arm member, and By rotating the clamping tool supported on the upper end of the shaft, the direction can be freely adjusted according to the deformation of the lower edge of the vehicle body, making it easy and quick to attach the clamping tool to the vehicle body. .

Furthermore, by adjusting the length of the arm member's outward protrusion, the arm member can be used for vehicle bodies of different widths.

Since the height and orientation of the clamping tool can be easily adjusted in this manner, the work efficiency for fixing the vehicle body can be dramatically improved.
