[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle body fixing device stand that immobilizes a vehicle body when repairing the vehicle body.

[Conventional technology]

To correct deformation caused by a car accident, the car body is immobilized and restored by pulling the deformed part of the car vertically or horizontally. As shown in Figs. 7 and 8, two screw jacks 9a are arranged along both side edges of the vehicle body, and the screw jacks 9 are attached to both ends of the pipes 30, 30 provided in the vehicle width direction.
It is inserted into the annular receiving piece 28 provided in a. Reference numeral 15a denotes a vehicle support fitting fixed to the pipe 30, and a plate-shaped body 17a in a direction perpendicular to the annular body 31 through which the pipe 30 is inserted is fixed by welding.
A pair of clamping pieces 18a, 18a are provided near both ends so that they can be tightened with tightening bolts 19a, 19a, and a bracket 22 is provided in the middle part.
A is fixed with a stopper bottle 23a, and through holes 20a and 21a are formed in the bracket 22a. 3
Reference numeral 32 indicates a stopper bottle screwed onto the annular body 31 to tighten the pipe 30. The through hole 20a has pipes 33, 33 arranged along both side edges of the vehicle body.
Insert both ends and connect these four pipes 30, 3.

Then, by rotating the operating rod 37 inserted into the screw shaft 14a of the screw jack 9a, the pipe 30 is lifted and the support fitting 15a is raised, thereby raising the entire pipe frame, and the clamping pieces 18a, 18a of each support fitting 15a are raised. The vehicle body was fixed by abutting against a predetermined location on the lower surface of both side edges of the vehicle body and sandwiching a part of the vehicle body.

[Problem that the invention aims to solve] In this way, the position of the screws is determined according to the width of the car, and the frame is assembled by passing more pipes and fixing them with screws. This required a great deal of effort and time, making it impossible to work efficiently. Furthermore, when repairing, to measure whether the car body has been restored to its original dimensions, reference points such as multiple drainage holes on the bottom of the car body are used, and a long and narrow measuring device is placed along the bottom of the car body. This was carried out by measuring between the respective reference points, but pipes in the vehicle width direction often became obstacles and interfered with the measurement.

[Means to solve the problem]

The present invention solves this problem by laying and fixing a pair of parallel pillars on the floor, and forming longitudinal guide holes along the central axis at both the front and rear ends of each pillar. At the same time, a side frame body having a narrow groove communicating with the longitudinal guide hole is fixed to the outer wall, and the base end fits and slides into the longitudinal guide hole, and the bottom plate of the screw jack is inserted. It has a structure in which a distal end receiving portion having a cross-sectional shape is projected outward from the proximal end, and screw receiving plates having downwardly inclined inclined plates fixedly attached to the front and rear sides of the proximal end are removably provided.

[Effect]

Place the car on the car body fixing device stand and temporarily float it above the floor using a table lifter, etc. In this state, screw jack receiving plates are fitted into the vertically elongated guide holes at the four corners, and screw jacks are further fitted into the screw jack receiving plates. Then, the screw jack is slid together with the screw jack receiving plate, and the clamping metal fitting attached to the head thereof is fixed at a predetermined location on the lower surface of both front side edges of the vehicle by clamping a part of the vehicle body. Once fixed, lower the table lifter. In this way, the vehicle body can be fixed easily and quickly.

〔Example〕

An embodiment of the present invention will be described below based on the drawings. Reference numerals 1a and 1b are a pair of pillars laid parallel to each other on the floor, and the distance between them is set to be slightly narrower than the width of a normal light vehicle. In addition, both pillar bodies 1a, 1b
are connected to each other by a seat plate 2 fixed to the floor surface with anchor bolts 3 at the front and rear ends and at an intermediate position. Then, side frames 4 of a predetermined length are fixed to the outer surfaces of both the front and rear ends of the columns 1a and 1b.
Each of the side frame bodies 4 has a longitudinally elongated guide hole 5 formed along the central axis, and a longitudinally elongated guide hole 5 is formed along the longitudinally elongated guide hole 5 on the outer wall opposite to the column bodies 1a, 1b.
A narrow groove 7 is opened which communicates with the groove and has a narrow width with vertical walls 6, 6 remaining at the top and bottom.

Reference numeral 8 denotes a screw jack receiving plate which is inserted into the longitudinal guide hole 5 and on which the screw jack 9 for supporting the vehicle body is placed. Tip receiving part 8 extending from 8a
b protrudes outward along the floor surface. The tip receiving portion 8b is formed into a substantially round-shaped cross section with flanges 8'b and 8'b left on both sides of the top wall and a notch in the center so that the bottom plate 10 of the screw jack 9 can be fitted therein. Then, downwardly inclined inclined plates 38, 38 are fixed to the front and rear sides of the tip receiving portion 8b, respectively. Further, screw holes 8'a, 8'a are provided horizontally through both left and right ends of the base end portion 8a, and stop bolts 11, 11 are screwed therein. The screw jack 9 is attached to the cylinder 12 on the top surface of the bottom plate 10.
is vertically established by welding, a female screw member 13 is fixed to the inner wall of the cylinder 12, and a screw shaft 14 is provided in the cylinder 12 so as to be movable up and down by being screwed into the female screw member 13. Further, the bottom plate 10 has a screw hole 10.
A, 10a are vertically penetrated, and stop bolts 10'a,
Screw on 10'a. Reference numeral 15 denotes a vehicle support fitting, in which a plate-shaped body 17 is vertically established on a flat plate 16, and a pair of clamping pieces 18, 18 can be tightened at both ends of the plate-shaped body 17 with tightening bolts 19, 19. A bracket 22 with through holes 20 and 21 formed in the middle portion thereof is fixed by a stop bolt 23, and a cap-shaped body 24 is fixed to the lower surface of the flat plate 16. Then, the cap-shaped body 24 fixed to the lower surface of the vehicle support fitting 15 is attached to the screw shaft 14 of the screw jack 9.
It is constructed by attaching it by placing it over the upper end.

In addition, in the present invention, a pair of columns 1a, 1b
In between, a table lifter T is installed under the floor to temporarily support the vehicle body in a lifted state.

Therefore, when fixing the vehicle body in a suspended state, a screw receiving plate 8 is inserted into the narrow guide hole 5.
, pull the car along the longitudinal direction of the pair of pillars 1a and 1b, place the car body directly above the pillars 1a and 1b, and operate the table lifter T to raise the car body to an appropriate height. Let it rise for a while. At this time, the car rides on each screw jack receiving plate 8 and is pulled in. However, since the screw jack receiving plate 8 is placed low on the floor and moves smoothly by the front and rear inclined plates 38, 38, the screw jack receiving plate 8 is pulled in. The plate 8 does not pose an obstacle. Next, the four screw receiving plates 8 are slid and placed at predetermined positions on the lower surface of both side edges of the vehicle body, and the stop bolts 11, 11 are tightened to fix them immovably. Next, insert and slide the bottom plate 10 of the screw jack 9 into each end receiving portion 8b having a cross-sectional shape, position the screw jack 9 on the lower surface of both side edges of the vehicle body, and similarly tighten the stop bolts 10'a, 10'a. After tightening and fixing, the vehicle support fitting 15 at the upper end is moved upward to sandwich a part of the vehicle body and firmly support it. Then, the table lifter T is lowered to complete the work of fixing the vehicle body, and a side length machine (not shown) is placed on the bottom of the vehicle body to carry out repairs while taking measurements.

In this way, the vehicle body can be easily fixed by simply sliding the screw jack receiving plate 8 and the screw jack 9, and the fixing work can be done easily and quickly regardless of the vehicle type, especially from narrow to wide vehicles. can be done.
