Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of positioning tooling, in particular to a device for preventing deformation of A-pillar foam parts. Background Technique
[0002] After the welding of the A-pillar foam part is completed, due to the U-shaped positioning design of the foam part, when the tooling is opened, the cylinder drives the U-shaped block to slide, and the foam part cannot be separated from the positioning block, resulting in deformation of the foam part and scrapping of the workpiece. The prior art cancels the overall structure of the original U-shaped structure of the foam part and decomposes the U-shaped structure into three sections. During the opening process of the tooling, the two-side positioning is respectively driven by cylinders to withdraw from the workpiece, avoiding the deformation of the foam part caused by the parallel sliding of the overall structure and the workpiece before. However, compared with the previous integral structure, the three-section structure is more complex, adding two groups of cylinders and increasing the manufacturing cost. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a device for preventing deformation of A-pillar foam parts, which changes the opening mode of workpiece positioning and avoids the deformation of workpieces during the production process.
[0004] Based on the above problems, the technical solution proposed by the utility model is a device for preventing deformation of A-pillar foam parts, including a base platform and a moving platform. On the moving platform, a first positioning block, a second positioning block and a third positioning block for clamping the U-shaped foam part are arranged. The outer sides of the first positioning block and the third positioning block are respectively connected with a first cylinder and a third cylinder. A second cylinder is arranged on the base platform, and the telescopic end of the second cylinder is fixedly connected with the moving platform and drives the moving platform to move up and down.
[0005] First inclined surfaces, third inclined surfaces and second inclined surfaces are respectively arranged on the opposite sides of the first positioning block and the third positioning block and the upper end part of the second positioning block, and the first inclined surface, the second inclined surface and the third inclined surface are respectively in contact with the outer sides of the U-shaped foam part first.
[0006] Sensors for detecting whether the foam part is placed in place are installed on both the first positioning block and the third positioning block.
[0007] Advantages and beneficial effects of the utility model: This application does not change the structure of the U-shaped foam part, decomposes the positioning of the U-shaped foam part into three-section positioning. After the tooling is opened, each positioning part is separated from the foam part respectively, that is, through the opening mode of workpiece positioning, the deformation of the workpiece during the production process is avoided, the scrapping caused by deformation is reduced, and the work efficiency is improved.

[0010] The following will describe in detail the specific implementation mode of the present utility model in conjunction with the attached drawings.
[0011] As Figure 1 shown, the technical solution proposed by the present utility model is:
[0012] An anti-deformation device for an A-pillar foaming part, comprising a base 10 and a moving table 9. On the moving table 9, a first positioning block 1, a second positioning block 2 and a third positioning block 3 for clamping the U-shaped foaming part 4 are arranged. The outer sides of the first positioning block 1 and the third positioning block 3 are respectively connected to a first cylinder 6 and a third cylinder 7. A second cylinder 8 is arranged on the base 10. The second cylinder 8 is located at the lower end of the moving table. The telescopic end of the second cylinder 8 is connected to the moving table 9 and drives the moving table 9 to move up and down.
[0013] Among them, the above-mentioned cylinder and the above-mentioned positioning block are fixedly connected, and can be, but not limited to, connected by means of screw connection, splicing connection or welding connection.
[0014] First inclined surfaces, third inclined surfaces and second inclined surfaces are respectively arranged on the opposite sides of the first positioning block 1 and the third positioning block 3 and the upper end part of the second positioning block 2. The first inclined surface, the second inclined surface and the third inclined surface are respectively first attached to the outer sides of the U-shaped foaming part 4.
[0015] Sensors 5 for detecting whether the foaming part is placed in place are installed on both the first positioning block 1 and the third positioning block 3. Preferably, a second sensor for detecting the moving distance of the moving table 9 is arranged on the base 10. The second sensor is arranged opposite to the bottom surface of the moving table 9.
[0016] When the tooling is opened, first, the first cylinder 6 and the third cylinder 7 drive the first positioning block 1 and the third positioning block 3 to move respectively, disengaging from the foaming part. Then, the second cylinder 8 moves, pulling the whole moving plate downward to disengage from the workpiece.
