Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a measuring device that is used for repairing silver and gold by applying an external force such as a tensile force to the body of an automobile that has been deformed due to a collision or the like. Regarding.

[Prior art and its problems] When repairing a car that has been deformed due to a collision, it is generally done by fixing the car body immovably on the ground, placing a clamp on the deformed part, and pulling it with a repair machine. Conventionally, in such repair work, in order to measure whether the car body has been repaired to its original dimensions, it was necessary to measure the dimensions between each reference point by applying a tension rod and a tape measure between multiple reference points on the bottom of the car body. It was very time consuming.

[Object and Structure of the Invention] Therefore, the present invention aims to provide a measuring machine for sheet metal repair that can improve the workability of silver and gold repair. A flexible horizontal rod is disposed perpendicular to the central vertical rod, and a reference point display is movably disposed on the vertical horizontal rod, so that it can be freely rotated in a horizontal plane at one end of the central vertical rod. It is characterized by being equipped with a telescopic length measuring rod and a protractor for reading its turning angle.

[Example] In the figure, l is a central vertical rod made of a square pipe on which a measuring scale 2 is displayed by pasting a measuring tape on the surface, and 2 on the central vertical rod 1 is perpendicular to the central vertical rod l. The book's movable horizontal rods 3 are disposed so as to be movable along the central vertical rod 1. That is, a receiving plate 4 is fixed to the lower surface of the center of the universal horizontal rod 3, and two rollers 5 are rotatably supported on the receiving plate 1 so as to sandwich the central vertical rod 1 from both sides. Therefore, the horizontal horizontal rod 3 can freely move along the central vertical rod 1 while maintaining a state perpendicular to the central vertical rod 1. A length measurement scale 6 is displayed on the surface of the universal horizontal rod 3, similar to the surface of the central vertical rod 1. Reference numeral 7 denotes a reference point display body that is vertically expandable and retractable, and a branch-shaped base 8 is disposed on the upper surface of the universal horizontal lever 3 so as to be movable along the universal horizontal lever 3. A pipe 9 is established, a small diameter pipe 10 is loosely fitted into the round pipe 9, a rod 11 is loosely fitted into the small diameter pipe 10, and a cone 12 is fixed to the upper end of the rod 11. In addition, 13 is a thumbscrew that stops the free movement of the base 8 on the flexible horizontal rod 3, 14 is a thumbscrew provided at the end of the round pipe 9 to stop the expansion and contraction of the small diameter pipe 10, and 15 is a thumbscrew that prevents the rod 11 from expanding and contracting. This is a thumbscrew provided at the end of the small diameter □ pipe 10 to stop it. An extension rod 16 is provided at the tip of the universal horizontal rod 3 so as to be extendable and retractable, and a reference point indicator 7' is also provided at the tip of the extension rod 16.

That is, a small diameter pipe 17 is connected to a thumbscrew 18 at the tip of an extension rod 16.
A retractable rod 19 is loosely fitted into the small diameter pipe 17, and a cone 20 is fixed to the upper end of the rod 19. 2
1 is a thumbscrew provided at the end of the small diameter pipe 17 to stop the rod 19 from expanding and contracting. Note that a length measurement scale 22 is also displayed on the surface of the extension rod 16.

On the other hand, reference numeral 31 denotes a square pipe-shaped horizontal support rod that supports the central vertical rod 1, and both ends of the central vertical rod 1 are fixed to the lower surface of the center of the horizontal support rod 31. In addition to pulleys 32 provided at both ends of the support horizontal rod 31, a screw shaft 33 for supporting legs is vertically supported and can be rotated by operating a handle 34 fixed to the upper end of the screw shaft 33. moves up and down so that its lower end can come into contact with the floor.

As shown in FIG. 2, a vertical shaft 35 is attached to a bearing 36.
6, a swivel base 37 is provided on the vertical axis 35, and a length measuring rod 38, which is extendable and retractable like a well-known rod antenna, is installed on the swivel base 37. That is, the measuring rod 38 has a medium diameter pipe 4o slidably inserted into a large diameter pipe 39, a small diameter pipe 41 further slidably inserted into the medium diameter pipe 40, and a large diameter pipe 39. Base end lower part 39a
is fixed to the upper surface of the swivel table 37, and the large diameter pipe 3
The base end upper part 39b of the winding drum 4 is opened.
A flexible measuring tape 45 is wound around the winding drum 42, and a window hole 46 is formed in the casing 44 so that the scale of the measuring tape 45 can be seen through. .

At the tip of the small-diameter pipe 41, there is a length measuring pointer 4 that can be expanded and contracted up and down.
7 is provided. That is, the length measuring pointer 47 is the small diameter pipe 41.
A pipe 48 is fixed vertically to the tip of the pipe 48, and a rod 5o having a cone 49 fixed to the upper end thereof is inserted through the pipe 48. 51 is a pipe 4 to stop the rod 50 from freely expanding and contracting.
It is a thumbscrew screwed into one side of 8. The lead-out part of the measuring tape 45 from the casing 44 is inserted into the small-diameter pipe 41, and its tip is anchored to the buried part of the pipe 48.

Therefore, when the length measuring rod 38 is expanded or contracted, the measure 45 is paid out or wound up from the winding drum 42, and the length measuring pointer is inserted into the window hole 46 from the vertical axis 35, which is the center of rotation of the length measuring rod 38. The distance on the horizontal plane up to 47 is displayed. 52 is a protractor provided at the center of the horizontal support rod 31 to detect the direction of rotation of the length measuring rod 3B, and 53 is an angle pointer provided on the swivel table 3). When the direction of the long rod 38 is changed, the angle can be read on the protractor 52 using the pointer 53.

However, in the measuring device constructed in this way, each reference point indicator 7,7' is first aligned with the measurement reference position of the vehicle according to a frame chart determined for each type of vehicle. To do this, the horizontal horizontal rod 3 is moved along the central longitudinal rod 1, the base 8 is moved on the horizontal horizontal rod 3, and the extension rod 1 is moved.
Expand/contract 6.

Then, the height of each reference point display body 7, 7' is adjusted to match the floor height of the car under repair, and the measuring device is inserted under the floor of the accident car by rolling the pulley 32. Then, move each reference point indicator 7°7' to the reference position I! of the underfloor surface of the accident vehicle. ! (Usually, the reference position is the drain hole or bolt head on the underside of the vehicle body.) Then operate the handle 34 to lower the supporting leg screw shaft 33 and place the lower end on the floor. By making contact, the slider 32 is floated from the floor surface to keep the measuring instrument horizontal and to prevent free movement. On the other hand, in an accident vehicle that has been deformed due to a collision, the reference position of the underfloor surface of the deformed part has shifted, but the length rod 38 is extended to the drain hole at the reference position where the shift occurred, as shown in Figure 3. The conical body 49 of the sub-length pointer 47 is made to match. Then, the deformed part is gripped by the clamp 54 and the tension cheno 56 is strongly pulled by a well-known pulling tool 55 to correct the deformed part. Returning to the original reference position can be measured using the measuring rod 38.

In other words, the restored state of the accident vehicle A can be seen from the window hole 46 of the length measuring rod 38.
This can be known by the dimensions read from the angle pointer 53 and the angle on the protractor read by the angle pointer 53. For this reason, while monitoring the restoration state, pull the tension chain 5 with the necessary force.
6 can be towed and work can be carried out accurately.

[Effect of the invention] By means of a vice-length rod at one end of the central vertical rod.

By detecting the distance and direction from that point,
Since the reference position of the accident vehicle can be determined accurately and easily, the workability of silver and gold repairs is greatly improved.
