Description

Technical Field

[0001] This utility model relates to the field of welding aluminum protective brackets for anti-collision beams, and in particular to a secondary feeding device for aluminum protective brackets. Background Technology

[0002] like Figure 7 In the prior art shown, the energy-absorbing box and the base plate are connected by welding to form a second weld, and the bracket and the base plate are connected by welding to form a first weld. In order to ensure the connection strength between the energy-absorbing box and the base plate, the bracket and the energy-absorbing box do not contact each other and leave a certain distance to accommodate the second weld. The top of the bracket is welded to the anti-collision beam on the top of the energy-absorbing box. In the welding process of the first and second welds in the prior art described above, since the bracket will block the welding of the second weld, the second weld needs to be welded first, and then the bracket needs to be clamped to weld the first weld and the anti-collision beam. Therefore, the base plate energy-absorbing box needs to be clamped before welding. After welding, the bracket is clamped and fixed by other fixtures before welding. However, this method has the following drawbacks: 1. Insufficient bracket positioning accuracy: Traditional single-feeding devices are difficult to achieve accurate bracket positioning; 2. Low efficiency of secondary clamping: Bracket welding requires two independent clampings, which require multiple manual adjustments and are time-consuming. Utility Model Content

[0014] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0015] Example: Figure 7 As shown, the base plate 5 is welded to the energy-absorbing box 4, and a second weld 402 is formed between the energy-absorbing box 4 and the base plate 5. An anti-collision beam (not shown) is provided above the energy-absorbing box 4. The bracket 3 is placed on the base plate 5 and welded to the base plate 5 and the anti-collision beam. A first weld 401 is formed between the bracket 3 and the base plate 5. Based on the positions and connections of the bracket 3, energy-absorbing box 4, and base plate 5, if the first weld 401 is welded first, the robot welding gun, due to its limited position, cannot weld the second weld 402. Therefore, the second weld 402 must be welded first, followed by the first weld 401. This necessitates the development of an additional fixture to weld the other parts first, and then weld the bracket 3 last, increasing development costs and worker loading / unloading time. The long welding interval for bracket 3 also increases the impact of thermal deformation. Therefore, a secondary aluminum feeding device is needed to solve these problems. Among them, according to Figure 7 In this application, the direction in which the bracket 3 faces the energy-absorbing box 4 is considered front, and vice versa; the direction in which the bracket 3 faces the base plate 5 is considered bottom, and vice versa; and the side refers to the left or right side, the specific side being determined by... Figures 1-7 For reference, one side and the other side have the same corresponding relationship as the left and right sides, and the overall symmetry will not affect the function of the feeding device; Furthermore, in this application, the bolt fixing method can be, but is not limited to, the following: one part has a stepped hole and another part has a threaded hole, and the two parts are connected by hexagon socket head cap screws. The specific number of hexagon socket head cap screws is determined to be sufficient to stably fix the two parts; and the design of the bolts will not affect the connection and operation of other parts. like Figures 1-3As shown, the feeding device includes a flipping structure 1, which includes a flipping cylinder body 101. Before welding, the base plate 5 and the energy-absorbing box 4 are positioned and fixed. After the support 3 is fixed by the feeding device of this application, the position of the support 3 is adjusted so that the support 3 moves to the designated position. The fixing method of the flipping cylinder body 101 and the welding device is based on the fact that the support 3 can accurately match the energy-absorbing box 4 and the base plate 5. For example, the flipping cylinder body 101 can be fixed by a three-axis slide table. The specific fixing method of the flipping cylinder body 101 can be appropriately adjusted according to the prior art. This application will not elaborate further. like Figures 1-3 As shown, a rectangular rotating shaft 102 is provided on the side of the tilting cylinder body 101. The rectangular rotating shaft 102 can be rotated by the drive of the internal structure of the tilting cylinder body 101. Tilting frames 103 are sleeved on both ends of the rectangular rotating shaft 102 extending outside the tilting cylinder body 101, so that the tilting cylinder body 101 can drive the tilting frame 103 to rotate 90 degrees. The front end of the tilting frame 103 is fixed with an L-shaped support frame 104 by screws, so that the tilting cylinder body 101 and the L-shaped support frame 104 form a tilting structure, thereby changing the position of the support 3 and switching the support 3 between the vertical state and the horizontal state. like Figures 1-3 As shown, the feeding device includes a support structure 7, which includes an L-shaped large support block 701. The front end of the tilting cylinder body 101 is fixed to the L-shaped large support block 701 by bolts. The horizontal block of the L-shaped large support block 701 faces upward, forming a horizontal platform. The upper part of the L-shaped large support block 701 is fixed to an L-shaped small support block 702 by bolts. One side of the L-shaped small support block 702 is vertical. The top of the L-shaped small support block 702 is fixed to a convex support block 703 by bolts. The lower part of the L-shaped support frame 104 is fixed to a concave support block 704 by bolts. When the support frame 3 is in a vertical state, the convex support block 703 and the concave support block 704 are in a vertical position. Figure 3 The vertical state of the bracket 3 is made more stable by the cooperation of the convex support block 703 and the concave support block 704. like Figure 4 and Figure 5As shown, a connecting cross block 201 is bolted to the side of the L-shaped support frame 104. A T-shaped connecting block 202 is bolted to the lower part of the connecting cross block 201. The cross block of the T-shaped connecting block 202 faces the front end and is arranged laterally. An installation cross block 203 is bolted to the front end of the T-shaped connecting block 202. A positioning pin 204 passes through the part of the installation cross block 203 that extends beyond the cross block of the T-shaped connecting block 202. The positioning pin 204 can cooperate with the hole on the bracket 3. A first positioning block 205 is integrally formed on the top of the installation cross block 203. The first positioning block 205 can serve as a reference block. When the bracket 3 is attached to the first positioning block 205, the upper part of the bracket 3 can stably contact the anti-collision beam. An L-shaped mounting plate 209 is bolted to one side of the L-shaped support frame 104. The L-shaped mounting plate 209 and the... The connecting horizontal block 201 is on the same side. One side plate of the L-shaped mounting plate 209 is located near the bracket 3. The outward bend of the L-shaped mounting plate 209 is fixed with a Z-shaped positioning side plate 206 by bolts. An adjusting bolt 207 is threaded onto the forward-extending side plate of the Z-shaped positioning side plate 206. By rotating the adjusting bolt 207, the length of the adjusting bolt 207 extending out of the Z-shaped positioning side plate 206 can be adjusted, thereby fine-tuning the angle of the bracket 3 so that the bracket 3 can fit with the energy-absorbing box 4. A second positioning block 208 is fixed to the front end of the L-shaped mounting plate 209. When the bracket 3 passes through the positioning pin 204, the bracket 3 is pushed so that the rear side of the bracket 3 initially fits with the first positioning block 205 and the second positioning block 208. The connecting horizontal block 201 and the L-shaped mounting plate 209 form a positioning structure to position the bracket 3. like Figure 6 As shown, the feeding device also includes a clamping structure 6, which includes an L-shaped support side plate 605. The L-shaped support side plate 605 is located at the inner bend of the L-shaped mounting plate 209, and the L-shaped support side plate 605 and the L-shaped mounting plate 209 are fixedly connected by bolts. A trapezoidal reinforcing rib plate 606 is welded to the rear side of the L-shaped support side plate 605. A clamping cylinder 601 is fixed to the front edge of the L-shaped support side plate 605. A push block 602 is fixed to the telescopic end of the clamping cylinder 601. A concave pressing plate 603 is fixed to the front end of the push block 602. The two protruding corners of the concave clamping plate 603 face the Z-shaped positioning side plate 206, and the rear edge of the protruding corner of the concave clamping plate 603 is provided with a bevel. Thus, when the clamping cylinder 601 pushes the concave clamping plate 603 to move towards the bracket 3, the bracket 3 can be pushed towards the first positioning block 205 through the bevel structure of the concave clamping plate 603. The rear side of the concave clamping plate 603 is integrally formed with a top clamping block 604. When the clamping cylinder 601 extends, the top clamping block 604 can act as a pushing structure to press the bracket 3 onto the Z-shaped positioning side plate 206.
