Description

Technical Field

[0001] This utility model relates to the technical field of clamping and positioning devices, and in particular to a clamping and positioning device for welding metal templates. Background Technology

[0002] Metal formwork is an important tool widely used in construction and industrial manufacturing. It is usually made of metal materials such as steel and aluminum alloys. With its high strength, high rigidity and good durability, it can accurately shape concrete structures in the construction industry, ensuring the forming quality and construction efficiency of buildings such as high-rise buildings and bridges. In industrial manufacturing, it serves as a mold or tooling fixture, providing precise shape and size standards for the processing of parts of various products. It is also reusable, effectively reducing production costs. It plays an indispensable role in promoting the development of construction and industrial production.

[0003] When welding metal templates, clamping and positioning devices are often used to position the templates to ensure the quality of the welding. In the existing technology, magnetic positioning devices are often used to adhere to and position the welding joints of the two templates when welding between templates. However, due to their own adsorption properties, magnetic positioning devices often adhere to nearby steel materials when in use. At the same time, it takes a lot of force to remove them from the metal templates, which makes them inconvenient to use. Therefore, a clamping and positioning device for welding metal templates has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping and positioning device for welding metal templates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping and positioning device for welding metal templates includes an L-shaped plate. A rectangular hole is formed at one end of the top of the L-shaped plate. A guide rod is fixedly connected to one end of each side of the rectangular hole. Rectangular blocks are slidably fitted onto both ends of the guide rod. A circular hole adapted to the guide rod is formed at one end of each of the two rectangular blocks. A bidirectional screw is rotatably connected between the ends of the rectangular holes away from the guide rod, and both ends of the bidirectional screw are threaded through the rectangular blocks. A screw nut adapted to the bidirectional screw is fixedly fitted onto one end of each of the two rectangular blocks. A knob is fixedly connected to one end of the bidirectional screw through the L-shaped plate. An oblique hole is formed on each of the two rectangular blocks, and a sliding rod is slidably connected into each of the two oblique holes. A T-shaped block is fixedly connected to the top of each of the two sliding rods. A clamping plate is fixedly connected to the bottom of each of the two sliding rods. A first rubber pad is fixedly connected to the side of each clamping plate that is close to it. By moving the rectangular blocks closer together or further apart, the initial position of the two clamping plates can be adjusted, facilitating the clamping and positioning of different second templates.

[0007] Preferably, a rectangular strip is provided at the rectangular hole at the top of the L-shaped plate, a T-shaped groove is provided at the bottom of the rectangular strip, and two T-shaped blocks are slidably connected in the T-shaped groove. Sliding rods are slidably fitted at both ends of the rectangular strip, and round holes adapted to the sliding rods are provided at both ends of the rectangular strip. Protrusions are fixedly connected to both ends of the two sliding rods, and four protrusions are fixedly connected to the top of the L-shaped plate.

[0008] Preferably, L-shaped side plates are fixedly connected to both sides of the top of the rectangular strip near the middle, and the same round rod is fixedly connected between the other ends of the two L-shaped side plates.

[0009] Preferably, a driving mechanism is provided at the end of the L-shaped plate away from the rectangular hole. The driving mechanism includes two vertical plates fixedly connected to the top of the L-shaped plate. The two vertical plates are rotatably connected to the same rotating rod. The rotating rod is fixedly connected to a rotating plate on the circumferential surface of the two vertical plates. A handle is fixedly connected to the top of the rotating plate, and a strip-shaped hole is opened in the middle of the rotating plate. A round rod is slidably connected in the strip-shaped hole. Both ends of the rotating rod are fixedly connected to ratchet wheels through the vertical plates. Both vertical plates are provided with round holes adapted to the rotating rod. By rotating the rotating plate, the rectangular strip moves closer to one side of the second rubber pad, thereby fixing and pressing the second template with the two clamping plates.

[0010] Preferably, the driving mechanism further includes two ratchet plates respectively disposed at the bottom of the two ratchet wheels. Vertical rods are slidably fitted at both ends of the two ratchet plates, and circular holes adapted to the vertical rods are opened at both ends of the two ratchet plates. The bottoms of the four vertical rods are fixedly connected to the top of the L-shaped plate, and protrusions are fixedly connected to the tops of the four vertical rods. Springs are fitted at the bottom of the four vertical rods. The ends of the two ratchet plates away from the rectangular holes are fixedly connected to the same U-shaped rod. Through the cooperation between the ratchet plates and the ratchet wheels, the rotating plate will not spring back when driving the rectangular bar to move, and will automatically lock.

[0011] Preferably, a second rubber pad is fixedly connected to the bottom of the L-shaped plate near the clamping plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By employing technologies such as clamping plates, sliding rods, T-blocks, driving mechanisms, rectangular bars, T-slots, and round rods, this device enables the second template to be clamped and pressed closer to the first template when the second template is vertically welded to the first template. This ensures a tight fit and positioning between the two templates, preventing wobbling during welding. Furthermore, pressing the U-shaped rod releases the device, effectively solving the inconvenience issues mentioned in the background technology. This allows for quick clamping and positioning of the second template with a simple push of the handle, ensuring a tight fit with the first template and providing stable working conditions for welding. The device is also simple and easy to understand to operate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-6 A clamping and positioning device for welding metal templates includes an L-shaped plate 1. A rectangular hole 101 is formed at one end of the top of the L-shaped plate 1. A guide rod 7 is fixedly connected to one end of both sides of the rectangular hole 101. Rectangular blocks 702 are slidably fitted onto both ends of the guide rod 7. A circular hole adapted to the guide rod 7 is formed at one end of each rectangular block 702. A bidirectional lead screw 701 is rotatably connected between the ends of the rectangular hole 101 away from the guide rod 7. Both ends of the bidirectional lead screw 701 are threaded through the rectangular blocks 702. A lead screw nut adapted to the bidirectional lead screw 701 is fixedly fitted onto one end of each rectangular block 702. One end of the bidirectional lead screw 701 passes through the L-shaped plate 1. A knob 704 is fixedly connected to the rectangular plate 1. Two oblique holes 703 are provided on each of the two rectangular blocks 702. Sliding rods 402 are slidably connected to the two oblique holes 703. T-shaped blocks 403 are fixedly connected to the top of each of the two sliding rods 402. Clamping plates 4 are fixedly connected to the bottom of each of the two clamping plates 4. A first rubber pad 401 is fixedly connected to the side of each clamping plate 4 that is close to it. The first rubber pad 401 can increase the friction between the clamping plates 4 and the second template 3. By rotating the knob 704, the two rectangular blocks 702 can move closer or further apart, thereby adjusting the initial position of the two clamping plates 4 and allowing for real-time adjustment according to the thickness of the second template 3.

[0023] In this utility model, a rectangular strip 6 is provided at the top of the L-shaped plate 1 where a rectangular hole 101 is opened. A T-shaped groove 601 is opened at the bottom of the rectangular strip 6, and two T-shaped blocks 403 are slidably connected in the T-shaped groove 601. Through the setting of the T-shaped groove 601, the rectangular strip 6 can drive the clamping plate 4 to move when it moves, and the two clamping plates 4 can move closer to each other. Sliding rods 602 are slidably sleeved at both ends of the rectangular strip 6. Round holes that match the sliding rods 602 are opened at both ends of the rectangular strip 6. Protrusions are fixedly connected to both ends of the two sliding rods 602, and four protrusions are fixedly connected to the top of the L-shaped plate 1.

[0024] In this utility model, L-shaped side plates 603 are fixedly connected to both sides of the top of the rectangular strip 6 near the middle, and the same round rod 604 is fixedly connected between the other ends of the two L-shaped side plates 603.

[0025] In this utility model, a driving mechanism 5 is provided at the end of the L-shaped plate 1 away from the rectangular hole 101. The driving mechanism 5 includes two vertical plates 501 fixedly connected to the top of the L-shaped plate 1. The two vertical plates 501 are rotatably connected to the same rotating rod 502. The rotating rod 502 is located on the circumferential surface of the two vertical plates 501 and is fixedly connected to a rotating plate 503. A handle 505 is fixedly connected to the top of the rotating plate 503. A strip hole 504 is opened in the middle of the rotating plate 503, and a round rod 604 is slidably connected in the strip hole 504. Both ends of the rotating rod 502 pass through the vertical plates 501 and are fixedly connected to ratchet 507. Both vertical plates 501 are provided with round holes that are adapted to the rotating rod 502.

[0026] In this utility model, the drive mechanism 5 also includes two ratchet plates 508 respectively disposed at the bottom of the two ratchet wheels 507. Vertical rods 509 are slidably sleeved at both ends of the two ratchet plates 508. Round holes adapted to the vertical rods 509 are opened at both ends of the two ratchet plates 508. The bottoms of the four vertical rods 509 are fixedly connected to the top of the L-shaped plate 1. Protrusions are fixedly connected to the tops of the four vertical rods 509. Springs 510 are sleeved at the bottom of the four vertical rods 509 located on the ratchet plates 508. The ends of the two ratchet plates 508 away from the rectangular hole 101 are fixedly connected to the same U-shaped rod 506. Through the configuration of the drive mechanism 5, when the rotating plate 503 drives the rectangular bar 6 to move, the rotating plate 503 will not spring back during operation. When disassembly is required, the ratchet plates 508 can be separated from the ratchet wheels 507 by pressing the U-shaped rod 506, allowing the rotating plate 503 to rotate freely.

[0027] In this utility model, a second rubber pad 102 is fixedly connected to the bottom of the L-shaped plate 1 near the clamping plate 4. The friction between the L-shaped plate 1 and the first template 2 can be increased by the second rubber pad 102.

[0028] Working principle: When welding the first template 2 and the second template 3, the second template 3 is first placed vertically to the first template 2. The L-shaped plate 1 is placed between the top intersections of the first template 2 and the second template 3, with the bottom of the L-shaped plate 1 flush with the top of the first template 2. The second rubber pad 102 of the L-shaped plate 1 contacts the side of the first template 2 away from the second template 3, and the two clamping plates 4 are located on both sides of the second template 3. Then, the handle 505 on the top of the rotating plate 503 is pulled towards one side of the second rubber pad 102. During this process, the round rod 604 slides in the strip hole 504, causing the rectangular strip 6, along with the two T-shaped blocks 403, the sliding rod 402, and the clamping plates 4, to move closer to one side of the second rubber pad 102. At the same time, under the action of the inclined hole 703, the two clamping plates... The holding plates 4 are brought close together and clamp the second template 3, while simultaneously pressing it towards one end of the first template 2 to facilitate welding. With the cooperation of the ratchet plate 508 and the ratchet wheel 507, the rotating plate 503 will not spring back when it rotates to a certain extent, thus locking itself. This ensures that the first template 2 and the second template 3 are tightly attached and will not shift, facilitating welding. After welding is completed, the U-shaped rod 506 is pressed to separate the ratchet plate 508 from the ratchet wheel 507. The rotating plate 503 is no longer limited, and the holding plates 4 will release the second template 3, allowing the device to move. When the thickness of the second template 3 is different, the initial position of the two holding plates 4 can be adjusted by rotating the knob 704 to bring the two rectangular blocks 702 closer together or further apart, improving practicality.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
