Description

[Detailed Description of the Invention] (Industrial Application Field) This invention particularly relates to a positioning block for vehicle body parts in the prototype stage of an automobile.

(Prior art) Conventionally, in the assembly process of body production at the prototype stage of an automobile, there was no dedicated assembly jig for the parts sent from the production process of each body part, since the specifications of each body part were different. Therefore, various methods were used to set the mounting positions of parts and perform assembly work.

(Problem to be Solved) Therefore, since there are no fixed mounting standards for the body parts of the prototype vehicle, it takes time and effort to set the mounting position, resulting in an extremely inefficient problem.

The mounting attachment includes a mounting plate having a mounting hole that matches the screw hole of the vehicle body part, and a split circle-shaped support shaft having a locking surface at the tip of the support shaft extending from the mounting plate. A receiving plate is integrally attached, and a fitting hole is formed in the center of the receiving plate along the axis of the support shaft, and the mounting reference attachment is the same as the board attached to the jig support. A receiving plate having approximately the same diameter as the receiving plate of the mounting attachment is provided at the tip of the support shaft extending from the board, and a contact surface and abutting surface of the receiving plate of the mounting attachment are provided on the receiving plate. A locking piece having a locking surface that fits is attached, a receiving portion for a mounting attachment is provided on the receiving plate, and a fitting shaft that fits into the fitting hole is formed protruding from the center of the receiving plate. Moreover, the support shaft has a connecting member consisting of a mounting board movably provided along the same axis and a connecting arm rotatably mounted on the board and sandwiching the receiving plates of both attachments.

Similarly, for the rear side member assembly (left) 33, the screw hole 35 for mounting the striker on the rear door 42 is d.
Attachments 20 are attached to locations e of the screw holes 36 for attaching the striker of the back door 43, respectively. Note that the attachment 20 is similarly attached to the right side member assembly 37 side. Each of the vehicle body parts 31, 34, 36 to which the attachment 20 is attached in this way
is sent to the assembly process.

On the other hand, in the assembly process, the jig supports 39 are erected at predetermined locations on the assembly surface plate 38, and the jig supports 39 are installed at predetermined height positions from the upper surface of the surface plate 38, that is, the left and right front side members are mounted. Each assembly 31 and rear side member assembly 34 with mounting attachments attached.
Attachment reference attachments 2 are installed at the relevant height positions at locations e, for example, with the locking surfaces 7 of the locking pieces 6 being vertical. Therefore, the vehicle body parts 31, 34, 3 sent from each manufacturing process
7 fits the fitting shafts 9 of the related mounting reference attachments 2 into the fitting holes 27 of the attached attachments 20 at the locations a to e, respectively, and attaches the locking surface 22 and the locking piece to the receiving plate 21. By engaging with the locking surface 7 of 6, the receiving plate 21 is housed in the receiving part 8 and is prevented from rotating, and each vehicle body part 31, 34, 3
7 is attached to a predetermined setting position, and the connecting member 10
By rotating the connecting arm 15 to sandwich the receiving plates 5, 21 of both attachments 2, 20, each vehicle body part 31, 34, 37 can be positioned and fixed. When the position is fixed in this way,
The mutual welding points 40 between each part are abutted, and welding work can be easily performed, and left and right sand member assemblies can be formed as assembly standards, and these left and right sand member assemblies can be Each vehicle body part, such as a roof panel, underbody, cowl top, etc., is then assembled using welding means and fastening members. When the assembly of each vehicle body part for the left and right side members was completed in this way, the connecting arm 15 was rotated to release the clamping state of the receiving plates 5 and 21, and the mounting attachment 20 was attached to the body side. In this state, remove the body from the assembly surface plate 38. After that, after removing the mounting bolt 28 of the mounting attachment 20, the mounting bolt 28 is inserted into each mounting screw hole 32, 33, 3.
