Embodiment Construction

[0024] Combine below figure 2 , 3 The present invention will be specifically described.

[0025] A hasp 4 is provided on the body mother part 1 installed on the threaded plate 2, and the hasp 4 is used as the pre-positioned parent body of the threaded plate 2, and a hasp through hole 3 or other for pre-positioning is processed on the threaded plate 2. Pre-positioning structure. The buckle 4 is integrated with the body mother part 1, and the buckle 4 is punched out on the body mother part 1.

[0026] On the production site, the threaded plate 2 is directly installed on the body mother part 1 and the buckle 4, such as figure 2 As shown, the buckle 4 is passed through the through hole 3 of the threaded plate, and then the buckle 4 is bent and flanged by means of hammering or welding a clamping device, such as image 3 As shown, the final pre-positioning purpose is achieved.

[0027] A sufficient adjustment gap is left between the hasp 4 and the through hole 3 on the thread...

Abstract

The invention discloses a method for pre-positioning a thread plate, comprising the following steps: 1) arranging hasps on a mother piece of a vehicle body; using the hasp and the mother piece as mother bodies for pre-positioning the thread plate (pre-positioning is finished by the combined action of the mother piece, the hasp and the thread plate); 2) processing hasp passing holes for pre-positioning or other pre-positioning structures on the thread plate; 3) installing the thread plate on the mother piece and the hasps to enable the hasps on the mother piece to pass through the passing holesof the thread plate or other pre-positioning structures; and 4) bending and flanging the hasps to finish the pre-positioning of the thread plate. The method has the advantages of obvious effects of low cost, light weight and simple operation and the method can be instantly applied to new vehicle types to realize the value of the method.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, in particular to the pre-positioning of an automobile mounting part-a threaded plate. Background technique [0002] At present, the pre-positioning of the threaded plate of the body-in-white is to place the threaded plate in a specially designed nut box, and then weld the nut box to the body panel, specifically as follows figure 1 As shown, but the existing pre-positioning scheme has the following defects: [0003] 1) The cost is increased, and the nut box is specially designed to pre-fix the threaded plate, which increases the cost (including stamping, welding and other manufacturing costs and management costs, etc.); [0004] 2) The weight of the body is increased. The nut box itself has a certain quality, but basically has no contribution to the rigidity and strength of the body. Canceling this part will have a certain significance for reducing the weight of the body and improving fuel...
