Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a vehicle body support and fixing device for horizontally and immovably supporting and fixing the vehicle body in order to repair a vehicle that has been deformed due to a collision or the like.

[Conventional technology]

When repairing damage to a car body that has been severely dented due to a collision, this is generally done by fixing the car body immovably to the ground, then grasping the dent with a clamp and pulling it outward. . The device for supporting and fixing the vehicle body during such repair work is disclosed in Japanese Utility Model Application No. 59-5456, which was previously filed by the present applicant.
There is a technique shown in the above publication (hereinafter referred to as the first prior art). This method involves placing four screws on a concrete floor, connecting the screws with two pipe-shaped horizontal and vertical rods to form a cross-shaped support, and then connecting the support with a chain. It was fixed to the floor and had a clamp member attached to the support base to receive the vehicle body.

Generally speaking, there is a jack for supporting a part of a vehicle body as disclosed in Japanese Utility Model Application Publication No. 49-94366 (hereinafter referred to as the second prior art). In this jack, a base metal fitting of the jack is loosely fitted into a slide groove provided on a slide table for lateral movement, and a jack main body that moves up and down is attached to the base metal fitting, and the jack body is attached to the center line of the slide table. The inserted spiral shaft is rotated by a crank handle, and the jack body can be moved left and right by the rotation of the spiral shaft.

[The problem that the idea attempts to solve]

Normally, when repairing this type of car body, various measuring machines are used to measure whether the recessed part has returned to its original state while proceeding with the pulling process. It needs to be fixed. Furthermore, when repairing a number of damaged cars, it may be necessary to move to a different workshop.

However, in the support fixing device of the first prior art, if the concrete floor surface is not kept flat and horizontal, when the screw jack is moved to match the size of the vehicle body, the screw jack may tilt or the height may increase. As the body moves up and down, it is impossible to horizontally support the car body without readjustment, and this time-consuming process poses a problem of poor operability. In addition, since each screwdriver is only placed on the floor, even if a fixing chain is stretched on the floor, the pulling direction will be in three-dimensional directions such as front and back, left and right, and up and down, so it will not work on the car body. could not be firmly fixed, causing problems in the tensioning work.

Further, since the jack of the second prior art is used simply by being installed on the floor, the same problems as those described above remain. In addition, the base metal fitting of the jack is difficult to move because it is moved by rotating the spiral shaft.
Moreover, since it is only installed on the floor surface, the fixing force for the vehicle body is weak, and there is a problem in that it is unsuitable for repair work of the vehicle body where tensile forces are applied in the front and rear, left and right, and up and down directions.

[Means to solve the problem]

Therefore, the present invention aims to solve all of the above-mentioned problems.In order to solve these problems, a pair of mounting plates each having a groove having a cross-sectional shape and having a plurality of horizontally protruding mounting pieces on both sides through which mounting bolts are inserted are provided. Lay the mounting rails horizontally and parallelly on the floor surface, insert the mounting bolts into each of the mounting pieces to removably fix each mounting rail to the floor surface, and insert the mounting rails into the grooves of each mounting rail. Two screw jacks that slide freely by loosely fitting rectangular seat plates at the lower ends of each screw jack are installed, and both ends of the two horizontal bars that are spanned between both mounting rails are connected to the upper ends of the respective screw jacks. A clamp member for receiving the vehicle body is mounted on the inner side of each screw jack of each of the horizontal bars so as to be slidable along each of the horizontal bars.

[Effect]

A plurality of anchor shafts are fixedly planted horizontally at appropriate positions on the floor surface, and a desired place is selected from among the anchor shafts, and a pair of mounting rails are respectively installed and fixed in parallel and horizontally using mounting bolts. If it is made removable in this way, it can be easily removed and moved to the required location for work. Furthermore, since the screwdriver is moved on the mounting rail, there is no need for readjustment even if the screwdriver is moved as long as the mounting rail is kept level.

By loosely fitting the seat plate of the screw jack into the groove of the mounting rail, it can be easily placed in a fixed position in the vertical direction under the vehicle body, and the vertical position can also be continuously adjusted by moving the screw jack up and down in the same place. It can be easily done within a few minutes. In addition, since the four screws are supported in the mounting rail, they are stable against tension in the vertical, horizontal, and longitudinal directions, and are superior in that they fully perform the function of supporting the vehicle body, contributing to improved work efficiency. do.

Furthermore, a total of four screw jacks are arranged on the mounting rail, and horizontal rods are connected to the left and right screw jacks, and in order to attach a clamp member to each screw jack, a clamping means is attached by pulling in the upward or longitudinal direction of the vehicle body. Parts of the image are not raised or distorted. Therefore, the vehicle body is securely fixed, and the tensile force necessary for correcting the deformed portion of the vehicle body is not wasted.

[Effect of idea]

Since the vehicle body support and fixing device for sheet metal repair of the present invention has the above configuration, if a horizontal level is set in advance at an appropriate position on the floor surface and multiple anchor bolts are firmly planted, the mounting rail can be secured by the mounting bolts. Because it is horizontally and removably fixed to the floor, it is easy to remove and can be moved to any desired location.
Work space can be used effectively by removing it when it is not needed.

In addition, since the screwdriver is moved on the mounting rail, keeping only the rail horizontal makes it easier to keep the screwdriver and therefore the clamping member horizontal, eliminating the need to maintain the floor surface flat and level. , which has the advantage of improved workability.

Furthermore, since each screw is housed within the mounting rail fixed to the floor surface, it is extremely stable and fully performs the function of supporting the vehicle body, so no additional support means are required and the configuration is simple. .
In addition, together with the integrated action of the cross-shaped vertical and horizontal rods connected to the screws, it is possible to firmly fix the vehicle body, so it can withstand tension in the vertical, horizontal, and longitudinal directions. This has the advantage that it can be corrected efficiently without wasting any data.

In addition, the screwdriver that slides on the mounting rail can adjust the lengthwise position of the screwdriver itself and the clamp member attached to the side beam according to the size of the vehicle body, as well as adjust the vertical position of the clamp member. Furthermore, the horizontal position of the vehicle body can be adjusted at the same place during the connection work, which has the advantage of improving work efficiency, and has many other beneficial effects.
