Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture for welding motor brackets. Background Technology

[0002] When installing the motor inside the outdoor unit of an air conditioner, a bracket is needed to secure the motor and ensure its stability. During the production of the bracket, the bent parts need to be welded. Nowadays, robotic arms are used for automated welding, requiring only manual loading, unloading, and fixing of the bracket by workers. However, when the bracket is placed on a workbench for welding, it still needs to be manually fixed by workers. This manual fixing can easily lead to displacement of the bracket, causing deviations in the welded parts and reducing the quality of the finished bracket. Utility Model Content

[0003] This utility model discloses a fixture for welding motor brackets, which solves the problem that manual fixing during bracket welding can easily cause the bracket to shift, resulting in deviations at the welded parts of the bracket.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A fixture for welding motor brackets includes a support platform and a bracket. The support platform has a worktable with a positioning post that can be inserted into a through hole in the bracket. The worktable has an opening. A push plate that can pass through the opening is provided below the worktable. A hydraulic rod for driving the push plate is fixed on the support platform. Upright plates are provided on both sides of the worktable, and rubber blocks that contact the bracket are fixed on the upright plates.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After placing the bracket on the workbench, insert the positioning pin into the through hole on the bracket to position it. Simultaneously, two rubber blocks contact both sides of the bracket to secure it. Then, the welding device mounted on the external robotic arm begins welding the bent parts of the bracket. Once welding is complete, the hydraulic rod drives the push plate upwards, lifting the bracket and separating the positioning pin from the through hole. The worker can then remove the bracket. This invention effectively secures the bracket, preventing displacement during processing, ensuring the accuracy of the welded parts, and eliminating the need for manual fixing, thus reducing the workload of workers.

[0012] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a fixture for welding a motor bracket, including a support platform 1 and a bracket 9. The support platform 1 has a worktable 2, on which a positioning post 22 can be inserted into a through hole in the bracket 9. The worktable 2 has an opening 24. Below the worktable 2 is a push plate 3 that can pass through the opening 24. A hydraulic rod 31 for driving the push plate 3 is fixed on the support platform 1. Vertical plates 4 are provided on both sides of the worktable 2, and rubber blocks 41 that contact the bracket 9 are fixed on the vertical plates 4. After the bracket 9 is placed on the worktable 2, the top of the positioning post 22 passes through the through hole in the bracket 9, completing the positioning of the bracket 9. At the same time, the vertical parts on both sides of the bracket 9 contact the rubber blocks 41 on the two vertical plates 4 respectively, and the two rubber blocks 41 can fix the bracket 9. The vertical plate 4 on the right side is higher than the vertical plate 4 on the left side (e.g., ...). Figure 1 (As shown in the image); when the staff starts the welding device installed on the external robotic arm, the support 9 can be welded. After the support 9 is welded, the hydraulic rod 31 can be started to drive the push plate 3 to move upward, so that the push plate 3 passes through the opening 24 and lifts the support 9 upward, so that the support 9 is separated from the positioning column 22. The staff can then remove the welded support 9.

[0014] like Figure 1 , Figure 2 and Figure 3As shown, the workbench 2 is rectangular, with a fixed beam 21 fixed to its inner side. Positioning posts 22 and openings 24 are respectively positioned on the fixed beam 21. A support rod 25 is fixed between the workbench 2 and the support platform 1. The horizontal section of the bracket 9, which fits onto the workbench 2, is also rectangular. The inner side of the bracket 9 has reinforcing beams corresponding to the fixed beam 21. Therefore, after the bracket 9 is placed on the workbench 2, the fixed beam 21 and the reinforcing beam inside the bracket 9 correspond to each other. The through holes on the bracket 9 are located on the reinforcing beams to facilitate the insertion of the positioning posts 22 into the through holes. When the push plate 3 passes through the opening 24, it can push the reinforcing beams on the inner side of the bracket 9 upwards, separating the positioning posts 22 from the through holes on the reinforcing beams. The support rod 25 can fix the workbench 2 onto the support platform 1.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, there are two fixed beams 21, which are symmetrically distributed from left to right. The push plate 3 is U-shaped, with its two ends corresponding to the two openings 24. The bracket 9 also has two reinforcing beams. The positioning posts 22 on the two fixed beams 21 are staggered from left to right, so that when the two positioning posts 22 are inserted into the holes on the two reinforcing beams, the bracket 9 can be effectively fixed, preventing displacement. The push plate 3 is U-shaped, so that when its two ends pass through the two openings 24, it can better lift the bracket 9 upwards, separating it from the worktable 2, allowing the worker to remove the bracket 9 from the worktable 2.

[0016] like Figure 2 and Figure 3 As shown, a screw 23 is fixed to the top of the fixed beam 21, and a positioning post 22 is threaded onto the screw 23. The diameter of the positioning post 22 increases from top to bottom. Depending on the inner diameter of the through hole on the inner side of the reinforcing beam of the bracket 9, the positioning post 22 can be removed, and then a positioning post 22 that matches the through hole on the reinforcing beam can be threaded onto the screw 23. The increasing diameter of the positioning post 22 from top to bottom facilitates smoother insertion of the positioning post 22 into the through hole on the reinforcing beam.

[0017] like Figure 1 and Figure 2As shown, two telescopic rods 5 are fixed on the support platform 1. The telescopic ends of the telescopic rods 5 are connected to the upright plate 4, and the upright plate 4 is slidably connected to the support platform 1. Two fixing blocks 32 that are symmetrical from left to right and penetrate the support platform 1 are fixed on the push plate 3. The opposite sides of the two fixing blocks 32 are inclined. Push rods 6 are fixed on the opposite sides of the two upright plates 4. The close ends of the two push rods 6 are in contact with the inclined sides of the two fixing blocks 32 respectively. The fixed end of the hydraulic rod 31 passes through the bottom of the support platform 1, and the telescopic end of the hydraulic rod 31 is fixed to the bottom of the push plate 3. When the hydraulic rod 31 is activated to drive the push plate 3 to move upward, the two fixed blocks 32 move upward as well. The fixed blocks 32 can then push the upright plate 4 away from the worktable 2 through the push rod 6. The upright plate 4 can then compress the telescopic end of the telescopic rod 5, causing the rubber block 41 to separate from the bracket 9. This allows the bracket 9 to be pushed upward more effectively when the top of the push plate 3 contacts the reinforcing beam on the bracket 9 (the reinforcing beam is not shown in the figure), thus avoiding the rubber block 41 from obstructing the movement of the bracket 9. The telescopic rod 5 includes a sleeve fixed to the support platform 1, a spring fixed inside the sleeve, and a sliding rod fixed to the spring inside the sleeve. The sliding rod is fixed to the upright plate 4.

[0018] like Figure 1 As shown, a support plate 7 fixed to the support rod 25 is provided below the workbench 2. A collection frame 8 is placed on the support plate 7, and an opening is provided on the upright plate 4 for one side of the collection frame 8 to pass through. After the bracket 9 is welded, the resulting welding slag and other impurities fall onto the workbench 2. When the bracket 9 is moved, the workers can clean the impurities into the collection frame 8 for centralized collection. Subsequently, the workers can pull the collection frame 8 out through the opening on the upright plate 4 to clean the impurities inside the collection frame 8.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
