Description

Technical Field

[0001] This application relates to the field of welding tooling technology, and in particular to a sheet metal welding positioning tooling. Background Technology

[0002] When processing sheet metal, positioning pieces need to be welded to it to increase its strength, and positioning fixtures are required during welding.

[0003] In existing technologies, welding the positioning piece to the sheet metal requires manual welding by workers. Hand welding is inefficient, unstable, prone to deviation after welding, and unsafe. Therefore, this application proposes a sheet metal welding positioning fixture to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a sheet metal welding positioning fixture, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a sheet metal welding positioning fixture, including a base plate, two pressing components symmetrically installed on the top of the base plate, two positioning components installed on the top of the base plate, and limit components installed on the inner walls of the two positioning components.

[0006] In a preferred embodiment, the crimping assembly includes a rotary crimping cylinder, which is fixedly installed on the top of the base plate. A connecting strip is fixedly connected to the output end of the rotary crimping cylinder, and a crimping strip is fixed to the bottom of the connecting strip.

[0007] By adopting the above technical solution, when the sheet metal is placed on top of the two positioning components, the connecting strip can be rotated to be above the sheet metal first, and then the pressing strip can be moved to be on top of the sheet metal. Thus, the two pressing components can be used to position the two sides of the sheet metal, ensuring that the sheet metal will not easily shake during welding.

[0008] In a preferred embodiment, the positioning component includes a positioning strip, which is fixedly installed on the top of the base plate. Two baffles are symmetrically fixedly installed on the outer side of the positioning strip. Two side plates are symmetrically welded to the outer side of the positioning strip, and a rotating plate is rotatably connected to the inner wall of the two side plates. Two magnetic columns are fixedly fixed on the outer side of the rotating plate, and two locking blocks are fixedly installed on the side of the rotating plate near the magnetic columns.

[0009] By adopting the above technical solution, after the pressing assembly positions the sheet metal, the positioning piece can be snapped onto the inner wall of the clamping block. Then, by rotating the rotating plate, the positioning piece can be stably positioned on the inner wall of the sheet metal, thereby ensuring the convenience of the robotic arm during welding and eliminating the need for hand-held operation, thus improving safety.

[0010] In a preferred embodiment, the positioning strip has two holes at its top, and the positioning strip is made of magnetic material.

[0011] By adopting the above technical solution, when the rotating plate positions the positioning piece on the inner wall of the sheet metal, the magnetic column can be inserted into the inner wall of the insertion hole. Then, the rotating plate can be stably positioned above the positioning strip by means of magnetic attraction, ensuring that it will not easily shift its position.

[0012] In a preferred embodiment, a pull rod is fixedly installed on the outer side of the rotating plate, and slots are formed on the inner wall of each of the locking blocks.

[0013] By adopting the above technical solution, the pull rod makes it easy for the user to press the rotating plate to make it rotate, and the slot makes it easy to position the positioning piece to be welded, ensuring that it will not shift its position during welding.

[0014] In a preferred embodiment, the limiting component includes a square groove, which is formed at the top of the positioning strip. A guide groove is formed at the bottom of the square groove. A slider is slidably connected to the inner wall of the guide groove. An abutment rod is fixedly installed at the top of the slider. One end of a return spring is fixedly connected to the outer side of the slider. The other end of the return spring is fixedly connected to the inner wall of the guide groove. A sliding rod is fixedly connected to the outer side of the slider.

[0015] By adopting the above technical solution, the pull connecting plate can simultaneously drive the two sliding rods to slide, thereby driving the slider and the abutment rod to slide on the inner walls of the guide groove and the square groove respectively. This can be used to limit the sheet metal placed on the top of the positioning strip, ensuring the stability of the sheet metal. Moreover, with the help of the elastic force of the return spring, the slider and the abutment rod can be pushed to move in time, thus facilitating the contact between the abutment rod and the sheet metal.

[0016] In a preferred embodiment, the slide rod is slidably connected to the inner wall of the positioning strip, and the ends of the two slide rods away from the slider are fixedly connected to a connecting plate.

[0017] By adopting the above technical solution, pulling the sliding rod can drive the slider and the abutment rod to slide on the inner walls of the guide groove and the square groove respectively, which can be used to limit the sheet metal placed on the top of the positioning strip, ensuring that it will not slide freely on the top of the positioning strip, and is suitable for positioning sheet metal of different sizes.

[0018] The beneficial effects of this application are: This sheet metal welding positioning fixture positions the positioning piece on the inner wall of the slot by placing the positioning piece to be welded to the sheet metal, and then rotating the rotating plate to insert the magnetic column into the inner wall of the insertion hole. This ensures that the positioning piece will not shift during welding, and eliminates the need for manual operation, thus improving accuracy and safety.

[0019] This sheet metal welding positioning fixture uses two sliding rods to drive a slider and abutment rod to slide on the inner walls of a guide groove and a square groove, respectively, by pulling a connecting plate. This can be used to limit the sheet metal placed on top of the positioning strip. The rotating pressing cylinder is driven to rotate the connecting strip to the top of the sheet metal, and then the pressing strip can be moved to the top of the sheet metal. Thus, the two pressing components can be used to position the two sides of the sheet metal, ensuring that the sheet metal will not easily shake during welding. Attached Figure Description

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] Reference Figure 1-4 A sheet metal welding positioning fixture includes a base plate 1, two pressing components 2 symmetrically installed on the top of the base plate 1, two positioning components 3 installed on the top of the base plate 1, and limit components 4 installed on the inner walls of the two positioning components 3.

[0024] See Figure 1The pressing assembly 2 includes a rotary pressing cylinder 201, which is fixedly installed on the top of the base plate 1. A connecting strip 202 is fixedly connected to the output end of the rotary pressing cylinder 201, and a pressing strip 203 is fixedly fixed to the bottom of the connecting strip 202. This allows the connecting strip 202 to be rotated to be above the sheet metal when the sheet metal is placed on top of the two positioning assemblies 3, and then the pressing strip 203 to be moved to be on top of the sheet metal. This allows the two pressing assemblies 2 to position the two sides of the sheet metal, ensuring that the sheet metal will not easily shake during welding.

[0025] See Figure 1 - Figure 3 The positioning component 3 includes a positioning strip 301, which is fixedly installed on the top of the base plate 1. Two baffles 302 are symmetrically fixedly installed on the outer side of the positioning strip 301. Two side plates 303 are symmetrically welded to the outer side of the positioning strip 301, and a rotating plate 304 is rotatably connected to the inner wall of the two side plates 303. Two magnetic columns 305 are fixedly fixed on the outer side of the rotating plate 304. Two locking blocks 308 are fixedly installed on the side of the rotating plate 304 near the magnetic columns 305. This allows the positioning piece to be locked onto the inner wall of the locking block 308 after the pressing component 2 has positioned the sheet metal. Then, the rotating plate 304 can be rotated to stably position the positioning piece on the inner wall of the sheet metal, thereby ensuring the convenience of the robot arm during welding and eliminating the need for hand-held operation, thus improving safety.

[0026] See Figure 2 The top of the positioning strip 301 has two insertion holes 307. The positioning strip 301 is made of magnetic material, so that when the rotating plate 304 positions the positioning piece on the inner wall of the sheet metal, the magnetic column 305 can be inserted into the inner wall of the insertion hole 307. Then, the rotating plate 304 can be stably positioned above the positioning strip 301 by means of magnetic attraction, ensuring that it will not easily shift its position.

[0027] See Figure 1 - Figure 3 A pull rod 306 is fixedly installed on the outer side of the rotating plate 304, and slots are provided on the inner wall of the locking block 308. The pull rod 306 makes it easy for the user to press the rotating plate 304 with their hand to make it rotate, and the slots facilitate the positioning of the positioning piece to be welded, ensuring that the position will not be offset during welding.

[0028] See Figure 1The limiting component 4 includes a square groove 401, which is formed at the top of the positioning strip 301. A guide groove 402 is formed at the bottom of the square groove 401. A slider 403 is slidably connected to the inner wall of the guide groove 402. An abutment rod 404 is fixedly installed at the top of the slider 403. One end of a return spring 405 is fixedly connected to the outer side of the slider 403. The other end of the return spring 405 is fixedly connected to the inner wall of the guide groove 402. A sliding rod 406 is fixedly connected to the outer side of the slider 403, so that pulling the connecting plate 5 can simultaneously drive the two sliding rods 406 to slide, thereby driving the slider 403 and the abutment rod 404 to slide on the inner walls of the guide groove 402 and the square groove 401, respectively. This can be used to limit the sheet metal placed on the top of the positioning strip 301, ensuring the stability of the sheet metal. With the help of the elastic force of the return spring 405, the slider 403 and the abutment rod 404 can be pushed to move in time, thus facilitating the contact between the abutment rod 404 and the sheet metal.

[0029] See Figure 3 and Figure 4 The slide rod 406 is slidably connected to the inner wall of the positioning strip 301. The ends of the two slide rods 406 away from the slider 403 are fixedly connected to the connecting plate 5. This allows the slider 403 and the abutment rod 404 to slide on the inner walls of the guide groove 402 and the square groove 401, respectively. This can be used to limit the sheet metal placed on the top of the positioning strip 301, ensuring that it does not slide freely on the top of the positioning strip 301. It is also suitable for positioning sheet metal of different sizes.

[0030] Working principle: First, the sheet metal can be placed on top of the positioning component 3. At the same time, the connecting plate 5 can be pulled to drive the slider 403 and the abutment rod 404 to slide on the inner walls of the guide groove 402 and the square groove 401 respectively using the two sliding rods 406. This can be used to limit the sheet metal placed on top of the positioning strip 301. Then, the rotary pressing cylinder 201 can be driven to rotate the connecting strip 202 to be above the sheet metal. Then, the pressing strip 203 can be moved to be on top of the sheet metal. Thus, the two pressing components 2 can be used to position the two sides of the sheet metal to ensure that the sheet metal will not easily shake during welding. Then, the positioning piece that needs to be welded to the sheet metal can be placed on the inner wall of the slot of the card block 308. Then, the rotating plate 304 is rotated to insert the magnetic column 305 into the inner wall of the insertion hole 307, which can position the positioning piece on the inner wall of the sheet metal to ensure that it will not shift during welding.
