Description

Technical Field

[0001] This application relates to the field of welding tooling equipment technology, and more specifically, to an L-shaped steel welding tooling fixture. Background Technology

[0002] L-shaped steel structures are highly industrialized and have good load-bearing performance, making them increasingly widely used in building structures. In the processing and utilization of L-shaped steel, it is usually necessary to splice two or more pieces together. The splicing of steel requires welding technology. To ensure that L-shaped steel of different sizes does not move during the welding process, welding fixtures for L-shaped steel have emerged.

[0003] Currently, most L-shaped steel welding fixtures on the market focus on facilitating welding. For example, Chinese patent (authorization announcement number CN214978896U) discloses an L-shaped steel welding fixture, including a base. Two symmetrical first rotating shafts are fixedly connected to the upper surface of the base. A bidirectional threaded rod is fixedly connected to the inner rings of the two first rotating shafts. A first throttle is fixedly connected to the right end of the bidirectional threaded rod. Two symmetrical internal threaded collars are provided on the outer ring of the bidirectional threaded rod. The inner rings of both internal threaded collars mesh with the outer surface of the bidirectional threaded rod. A linkage rod is fixedly hinged to the upper surface of each of the two internal threaded collars via a pin. A connecting support platform is fixedly connected to the upper surface of the base. This L-shaped steel welding fixture, by setting the bidirectional threaded rod and rotating the first throttle, allows the two internal threaded collars to move left and right, thereby raising and lowering the load-bearing rod. The addition of a spring enhances the lifting force, saving effort. The rotating plate allows the L-shaped steel to be rotated during welding, facilitating the welding process.

[0004] Regarding the aforementioned technologies, the inventors believe that the welding process of welding clamps on the market is cumbersome and the welding position is prone to shift during welding, affecting production quality and construction efficiency. At the same time, the clamp size of L-shaped steel welding fixtures is limited and cannot meet the construction needs of modern buildings with diverse building materials. Utility Model Content

[0005] To address the aforementioned problems, this application provides an L-shaped steel welding fixture.

[0006] The L-shaped steel welding fixture provided in this application adopts the following technical solution:

[0007] A welding fixture for L-shaped steel includes a main board. A control panel and a mounting frame are mounted on the upper surface of the main board. A slot is formed on the upper surface of the control panel. A cylinder is housed inside the control panel. A first reciprocating rod is movably connected to the output end of the cylinder. A welding head is sleeved on the outer side of the first reciprocating rod. A support frame is fixedly connected to the other side of the control panel. A second reciprocating rod is mounted on the side of the support frame closest to the control panel. A first moving block is movably connected to the other side of the second reciprocating rod. A welding clamp is mounted at the other end of the first moving block. The welding clamp includes a clamping block. A threaded rod is movably connected inside the clamping block. A gripper is drivenly connected to the outer side of the threaded rod. A sliding groove is formed on the outer side of the clamping block. A knob is mounted at the end of the threaded rod extending to the outer side of the clamping block. A rubber layer is fixedly connected to the inner wall of the gripper.

[0008] Furthermore, a controller is fixedly connected to the outside of the control panel, and the cylinder, the second reciprocating rod, and the third reciprocating rod are all electrically connected to the controller.

[0009] By using the above technical solution, the cylinder, the second reciprocating rod, and the third reciprocating rod are electrically connected by a controller, which can control their switching and movement, thereby achieving the overall operation of the device.

[0010] Furthermore, a third reciprocating rod is provided on the side of the mounting bracket near the control panel, and a placement plate is fixedly connected to the other end of the third reciprocating rod, which is movably connected to the other side of the second moving block.

[0011] Through the above technical solution, the controller can control the back-and-forth movement of the third reciprocating rod, thereby driving the reciprocating movement of the second moving block mounted on its outer side. A placement plate is fixedly connected to the outer side of the second moving block, and the L-shaped rod to be welded is placed on it. By driving the back-and-forth movement of the placement plate, the L-shaped rod is transferred to the area directly below the welding head, thus realizing the welding of the L-shaped rod.

[0012] Furthermore, the welding head extends to the outside of the slot and is located between the gripper and the limiting plate.

[0013] The above technical solution enables the reciprocating movement of the welding head inside the control panel by using a cylinder. The welding head is positioned between the gripper and the limiting plate. When the L-shaped steel to be welded is transported to fit against the L-shaped steel in the gripper, it can be welded into one piece by the welding head.

[0014] Furthermore, the placement plate has a recess inside, and the size of the groove is the same as the size of the recess.

[0015] With the above technical solution, the recesses and slots inside the placement plate are of the same size. When the L-shaped steel to be welded is transported to fit with the L-shaped steel in the clamp, the welding head moves to the welding position in the slot under the control of the cylinder to complete the welding work of the steel body.

[0016] Furthermore, the upper surface of the placement plate is provided with limiting plates, and six sets of limiting plates are provided and located on the side away from the support frame.

[0017] The above technical solution utilizes a limiting plate to prevent the welding position from shifting during the welding of L-shaped steel, thus ensuring the accuracy of the welding.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] Turning the knob rotates the threaded rod, which in turn causes the clamps mounted on its outer side to close. After the L-shaped steel to be welded is clamped by the clamps, it is moved to the top of the groove near the welding head. The controller can control the back-and-forth movement of the third reciprocating rod, which in turn drives the reciprocating movement of the second moving block mounted on its outer side. A placement plate is fixedly connected to the outer side of the second moving block. The L-shaped steel to be welded is placed on it. By driving the back-and-forth movement of the placement plate, the L-shaped steel is transferred to the bottom of the welding head. The limiting plate can prevent the welding position from shifting during the welding operation of the L-shaped steel to be welded, thus ensuring the accuracy of the welding.

[0029] Example 1:

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses an L-shaped steel welding fixture; please refer to [link / reference]. Figure 1The system includes a main board 1, a control panel 2 and a mounting bracket 3 on the upper surface of the main board 1, a slot 201 on the upper surface of the control panel 2, a cylinder 202 inside the control panel 2, a first reciprocating rod 203 movably connected to the output end of the cylinder 202, a welding head 204 sleeved on the outer side of the first reciprocating rod 203, a support frame 205 fixedly connected to the other side of the control panel 2, a second reciprocating rod 206 on the side of the support frame 205 near the control panel 2, a first moving block 207 movably connected to the other side of the second reciprocating rod 206, a welding clamp 4 at the other end of the first moving block 207, a clamp 4 including a clamping block 401, a threaded rod 402 movably connected inside the clamping block 401, a gripper 403 drivingly connected to the outer side of the threaded rod 402, a sliding groove on the outer side of the clamping block 401, a knob at the end of the threaded rod 402 extending to the outer side of the clamping block 401, and a rubber layer fixedly connected to the inner wall of the gripper 403.

[0032] A controller 208 is fixedly connected to the outside of the control panel 2. The cylinder 202, the second reciprocating rod 206, and the third reciprocating rod 301 are all electrically connected to the controller 208. By using the controller 208 to electrically connect the cylinder 202, the second reciprocating rod 206, and the third reciprocating rod 301, it is possible to control their switching and movement, thereby achieving the overall operation of the device.

[0033] A third reciprocating rod 301 is provided on the side of the mounting bracket 3 near the control panel 2. The other side of the third reciprocating rod 301 is movably connected to the second moving block 302, and the other end is fixedly connected to the placement plate 303. The controller 208 can control the back-and-forth movement of the third reciprocating rod 301, thereby driving the reciprocating movement of the second moving block 302 mounted on its outer side. The placement plate 303 is fixedly connected to the outer side of the second moving block 302. The L-shaped rod to be welded is placed on it. By driving the back-and-forth movement of the placement plate 303, the L-shaped rod is transferred to the area directly below the welding head 204, thereby achieving the welding of the L-shaped rod.

[0034] The welding head 204 extends to the outside of the slot 201 and is located between the gripper 403 and the limiting plate 304. It can be driven by the cylinder 202 to reciprocate within the control panel 2. The welding head 204 is positioned between the gripper 403 and the limiting plate 304. When the L-shaped steel to be welded is transported to fit against the L-shaped steel in the gripper 403, it can be welded into one piece by the welding head 204.

[0035] The placement plate 303 has a recess inside, and the size of the slot 201 is the same as the size of the recess. Since the recess and slot 201 inside the placement plate 303 are the same size, when the L-shaped steel to be welded is transported to fit with the L-shaped steel in the clamp 403, the welding head 204 moves to the welding position in the slot 201 under the control of the cylinder 202 to complete the welding work of the steel body.

[0036] The upper surface of the placement plate 303 is provided with a limiting plate 304. There are six sets of limiting plates 304, which are located on the side away from the support frame 205. The limiting plates 304 can prevent the welding position from shifting when welding L-shaped steel, thus ensuring the accuracy of welding.

[0037] The implementation principle of the L-shaped steel welding fixture in this application embodiment is as follows: turning the knob drives the threaded rod 402 to rotate, which in turn drives the clamp 403 installed on its outer side to close. After the L-shaped steel to be welded is clamped by the clamp 403, it is moved to the top of the slot 201 and close to the welding head 204. The controller 208 can control the back-and-forth movement of the third reciprocating rod 301, which in turn drives the reciprocating movement of the second moving block 302 installed on its outer side. The outer side of the second moving block 302 is fixedly connected to the placement plate 303. The L-shaped rod to be welded is placed on it. By driving the back-and-forth movement of the placement plate 303, the L-shaped rod is transferred to the bottom of the welding head 204. The limiting plate 304 can ensure that the welding position does not shift during the welding operation of the L-shaped steel to be welded, thereby ensuring the accuracy of welding.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
