Description

Technical Field

[0001] This utility model relates to the field of automotive parts welding technology, specifically to a limiting fixture for the upper front panel parts. Background Technology

[0002] The front bulkhead is a partition between the engine compartment and the passenger compartment of a car, and it is fixedly connected to the floor and front pillars of the chassis. The front bulkhead is a large stamped part, typically consisting of an upper and lower assembly. The upper assembly provides support and mounting points for components such as the windshield wipers, air conditioning system, hood hinges, and dashboard assembly, playing a crucial role in ensuring the torsional rigidity of the vehicle body, improving cabin comfort, and enhancing collision safety. The upper bulkhead assembly is generally welded together from components such as the upper front panel, lower front panel, and reinforcing plates. It typically employs a box-section structure with high torsional rigidity. The upper front panel is welded to the front pillars on the left and right side panels of the vehicle body via end plates on both sides, and is a major structural component determining the torsional rigidity of the vehicle body. A thin plate part, such as..., is located on the upper front panel of a certain model of car. Figure 1 As shown, the part is a sheet metal part, which is made by stamping and bending. The part has multiple through holes and bends on both sides. The bends on both sides are symmetrically arranged. There is a protrusion in the middle of one side of the part. When welding the part to the upper plate of the front bulkhead, it needs to be positioned. In the existing technology, the part is welded by hand, which makes it difficult to ensure its accurate position. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem solved by this utility model is to provide a limiting tooling for the upper part of the front bulkhead, so as to solve the problem of inaccurate positioning caused by hand welding of existing parts.

[0004] To solve the above problems, the technical solution adopted by this utility model is: a front upper plate part limiting fixture, including a limiting base, a positioning plate, a positioning block and a clamping block. The limiting base is used to place the part, and the limiting base is provided with a groove for cooperating with the middle part of the part. The positioning plate is fixedly installed above the limiting base by a bracket, and the side of the positioning plate corresponds to the position of the bent part of the part, and is used to position the bent parts on both sides of the part. The positioning block is fixedly set on the limiting base and abuts against the side of the part. The inner side of the positioning block is aligned with the edge of the groove of the limiting base. The clamping block is detachably installed on the base for clamping the part.

[0005] Furthermore, the groove of the limiting base is provided with a limiting groove corresponding to the protrusion in the middle of the part.

[0006] Furthermore, the positioning block has an inclined surface on its inner side.

[0007] Furthermore, the width of the groove is consistent with the width of the middle part of the part.

[0008] Furthermore, the positioning plate is generally rectangular in shape, and is horizontally positioned above the limiting base, with the outer side of the positioning plate abutting against the inner side of the bent portion of the part.

[0009] Furthermore, the clamping block is mounted on the base by screws, the clamping block has through holes for mounting screws, and the base has threaded holes for engaging with screws.

[0010] The beneficial effects of this solution are as follows: Compared with the prior art, the front upper plate part limiting fixture of this utility model limits the part in the vertical and horizontal directions by setting a limiting base, positioning the part in the length and width directions by setting a positioning plate and positioning block, and clamping the part by setting a clamping block. This limiting fixture can ensure the accurate positioning of the part and can also determine whether the length and width dimensions of the part meet the requirements. Positioning and clamping the part before welding can ensure the accurate welding position and improve the welding quality. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Implementation, for example, attached Figures 2 to 3As shown: A front upper plate part limiting fixture includes a limiting base 1, a positioning plate 2, a positioning block 3, and a clamping block 4. The limiting base 1 is used to place the part. The limiting base 1 has a groove 101 for mating with the middle of the part. The groove 101 of the limiting base 1 has a limiting groove 102 in the middle, which corresponds to the protrusion in the middle of the part, positioning the middle of the part and limiting the left and right directions of the part. The width of the groove 101 is the same as the width of the middle of the part. If the middle of the part cannot be placed in the groove 101 or the gap between the middle of the part and the groove 101 is too large, the part size is unqualified and rework is required. The positioning plate 2 is fixedly installed above the limiting base 1 by a bracket. The side of the positioning plate 2 corresponds to the position of the bent part of the part and is used to position the bent parts on both sides of the part. The positioning plate 2 is generally rectangular and is horizontally set on the limiting base 1. Above the base 1, the outer side of the positioning plate 2 abuts against the inner side of the bent part. If the distance between the bent part and the positioning plate 2 is large, the part size does not meet the requirements and needs to be reworked. The positioning block 3 is fixedly set on the limiting base 1 and abuts against the side of the part. The inner side of the positioning block 3 is aligned with the edge of the groove 101 of the limiting base 1. The inner side of the positioning block 3 is provided with a slope. If the part size meets the requirements, it can be smoothly placed into the groove 101 of the limiting base 1. If the part width is too large, it will be stuck on the slope of the positioning block 3. The clamping block 4 is detachably installed on the base for clamping the part. The clamping block 4 is installed on the base by screws 5. The clamping block 4 is provided with a through hole for installing the screws 5. The base is provided with a threaded hole that mates with the screws 5. After the part is positioned, the clamping block 4 and the base are used to clamp the part to ensure accurate welding position.

[0014] The specific implementation process is as follows: In use, place the protrusion in the middle of the part into the limiting groove 102 in the groove 101 of the limiting base 1, and rotate the part downwards so that the side of the part away from the protrusion is close to the positioning block 3. If the part can be placed in the groove 101 and the gap between the part and the side of the groove 101 meets the requirements, the part is qualified. If the part is stuck on the inclined surface inside the positioning block 3, the width of the part does not meet the requirements and rework can be carried out in time. If the distance between the bent part on both sides of the part and the positioning plate 2 is large during the process of placing the part into the groove 101, the length of the part does not meet the requirements and rework is required. If the part is placed in the groove 101 and its length and width both meet the requirements, use screws 5 to install clamping blocks 4 on the limiting base 1 so that clamping blocks 4 and limiting base 1 clamp the part, completing the positioning and clamping of the part, and the subsequent welding operation can be carried out. The limiting fixture can ensure the accurate welding of the part and improve the processing quality.
