Description

Technical Field

[0001] This utility model relates to the technical field of component welding, specifically to a special welding equipment for L-shaped plates. Background Technology

[0002] When assembling the wall-hung toilet bracket, the corresponding nuts 1 need to be pre-welded onto the L-shaped plate 2 of the wall-hung bracket (see...). Figure 1 Currently, the assembly process involves placing L-shaped plates on a flat surface and manually placing nuts into their corresponding positions. Then, a handheld welding machine is used to assemble and weld the wall mount and nuts. This process requires precise manual positioning of the nuts before welding, and in practice, the nuts are prone to displacement. Furthermore, manual welding is relatively inefficient, leading to insufficient production capacity and an inability to meet the demands of large-scale production. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a dedicated welding equipment for L-shaped plates. It mechanically feeds L-shaped plates and nuts, and then automatically welds the components together, achieving high dimensional accuracy and high production efficiency.

[0004] A special welding equipment for L-shaped plates, characterized in that it comprises:

[0005] Base plate;

[0006] The nut feeding mechanism is specifically a first linear feeder, which is equipped with a nut feeding track, and the first linear feeder steps to deliver the nut.

[0007] A nut transfer mechanism includes a first clamping mechanism and a first Y-axis feeding module. The first clamping mechanism is fixedly mounted on the first Y-axis feeding module at the end position facing the nut feeding track. The first clamping mechanism is used to clamp the nut located at the end of the nut feeding track.

[0008] The L-shaped sheet material feeding mechanism is specifically a second linear conveying mechanism, which is equipped with an L-shaped sheet material feeding track, and the bottom plate of the L-shaped sheet material is supported on the L-shaped sheet material feeding track for conveying.

[0009] The L-shaped plate transfer mechanism includes an L-shaped plate positioning frame, a first lifting mechanism, an X-direction pushing mechanism for the L-shaped plate, and an L-shaped plate clamping mechanism.

[0010] A positioning fixture assembly includes a lower positioning base plate and an upper pressing assembly, wherein the pressing block of the upper pressing assembly presses the nut onto the upper surface of the base plate of the L-shaped plate.

[0011] The positioning fixture transfer mechanism includes a second Y-axis track and a second Y-axis pushing mechanism;

[0012] The welding assembly includes a welding base plate, a welding machine, and a welding machine moving module. The welding base plate is equipped with the welding moving module, and the welding machine is mounted on the welding machine moving module. The welding machine moving module drives the welding head of the welding machine to complete the welding operation on the L-shaped plate and the nut.

[0013] Its further features are:

[0014] The L-shaped plate feeding track of the L-shaped plate feeding mechanism will step-transport the L-shaped plate to the upper surface of the L-shaped plate positioning frame and limit it by the outer baffle limiting mechanism. The lower part of the L-shaped plate positioning frame is provided with the first lifting mechanism. The first lifting mechanism drives the L-shaped plate positioning frame to rise. The claw end of the L-shaped plate clamping mechanism clamps the upper convex area of ​​the upright plate of the L-shaped plate. The X-direction pushing mechanism of the L-shaped plate drives the L-shaped plate clamping mechanism to move in the X direction, so that the L-shaped plate enters the contour positioning stop area of ​​the lower positioning base plate of the positioning fixture assembly.

[0015] The welding assembly includes two sets of welding machines. The two sets of welding machines weld the corresponding side connecting edges of the nut and the base plate of the L-shaped plate, respectively. The welding on both sides is carried out simultaneously to ensure efficient and stable welding.

[0016] Each welding machine is installed on a corresponding deflection moving seat. The deflection moving seats on both sides are supported by the X-direction translation seat body. The X-direction translation seat body is externally connected to an X-direction drive assembly. The X-direction drive assembly, the X-direction translation seat body, and the two sets of deflection moving seats are combined to form a welding machine moving module.

[0017] The second Y-axis pushing mechanism moves the positioning fixture assembly back and forth along the second Y-axis track from the positioning installation station and the welding station.

[0018] The welding station is provided with a pusher cylinder on the outer side of the positioning fixture assembly in the X direction, and a material box is provided on the inner side of the welding station in the X direction. The pusher cylinder pushes the welded component away from the positioning fixture assembly and into the material box.

[0019] The nut feeding track has openings on both sides at its ends, and the gripper ends of the first clamping mechanism clamp the nut through the openings on both sides.

[0020] The nut transfer mechanism also includes an X-axis drive mechanism. After the nut is gripped by the jaws of the first clamping mechanism, the X-axis drive mechanism retracts the nut in the X direction. When the nut is transferred to the corresponding position in the Y direction of the positioning fixture assembly, the X-axis drive mechanism drives the nut to move in the X direction until it is accurately placed in the corresponding position on the bottom plate of the L-shaped plate. Then, the Z-axis pressing mechanism of the upper pressing assembly drives the pressing block to press down and press the nut to stabilize it. After that, the first clamping mechanism is released, and the X-axis drive mechanism drives the first clamping mechanism to retract in the X direction and then reset to the initial position of clamping the nut.

[0021] After adopting the above technical solution, the L-shaped plate is transferred to the corresponding position of the lower positioning base plate of the positioning fixture assembly by the L-shaped plate transfer mechanism. Then, the nut is transferred to the corresponding position of the upper surface of the bottom of the L-shaped plate of the positioning fixture assembly by the nut transfer mechanism. Then, the pressure block presses the nut onto the upper surface of the base plate of the L-shaped plate. After that, the L-shaped plate transfer mechanism and the nut transfer mechanism are reset. The positioning fixture transfer mechanism transfers the positioning fixture assembly to the corresponding position of the welding station. The welding machine moving module drives the welding head of the welding machine to complete the welding operation of the L-shaped plate and the nut. The L-shaped plate and the nut are mechanically conveyed and fed. Then, the assembly is completed by automated welding. The assembly has high dimensional accuracy and high production efficiency.

[0037] The positioning fixture transfer mechanism 70 includes a second Y-axis track 71 and a second Y-axis pushing mechanism 72;

[0038] The welding assembly 80 includes a welding base plate 81, a welding machine 82, and a welding machine moving module 83. The welding base plate 81 is equipped with a welding moving module 83, and the welding machine 82 is equipped on the welding machine moving module 83. The welding machine moving module 83 drives the welding head of the welding machine 81 to complete the welding operation on the L-shaped plate 2 and the nut 1.

[0039] In a specific embodiment, the L-shaped plate feeding track 41 of the L-shaped plate feeding mechanism 40 steps and transports the L-shaped plate 2 to the upper surface of the L-shaped plate positioning frame 51, and is limited by the outer baffle limiting mechanism 511. The lower part of the L-shaped plate positioning frame 51 is provided with a first lifting mechanism 52. The first lifting mechanism 52 drives the L-shaped plate positioning frame 51 to rise. The claw end of the L-shaped plate clamping mechanism 54 clamps the upper convex area of ​​the upright plate of the L-shaped plate 2. The X-direction pushing mechanism 53 of the L-shaped plate drives the L-shaped plate clamping mechanism 54 to move in the X direction, so that the L-shaped plate 2 enters the contour positioning stop area of ​​the lower positioning base plate 61 of the positioning fixture assembly 60.

[0040] In a specific embodiment, the welding assembly 80 includes two sets of welding machines 82. The two sets of welding machines 82 respectively weld the corresponding side connecting edges of the bottom plate of the nut 1 and the L-shaped plate 2.

[0045] After the X-axis drive mechanism 33 clamps the nut 1 at the claw end of the first clamping mechanism 31, it retracts the nut in the X direction. When the nut 1 is transferred to the corresponding position in the Y direction of the positioning fixture assembly 60, the X-axis drive mechanism 33 drives the nut 1 to move in the X direction until it is accurately placed in the corresponding position on the bottom plate of the L-shaped plate 2.

After that, the first clamping mechanism 31 is released, and the X-axis drive mechanism 33 drives the first clamping mechanism 31 to retract in the X direction and then reset to the initial position of clamping the nut.

[0046] Its working principle is as follows: The L-shaped plate is transferred to the corresponding position of the lower positioning base plate of the positioning fixture assembly by the L-shaped plate transfer mechanism. Then, the nut is transferred to the corresponding position of the upper surface of the bottom of the L-shaped plate of the positioning fixture assembly by the nut transfer mechanism. Then, the pressure block presses the nut onto the upper surface of the base plate of the L-shaped plate. After that, the L-shaped plate transfer mechanism and the nut transfer mechanism are reset. The positioning fixture transfer mechanism transfers the positioning fixture assembly to the corresponding position of the welding station. The welding machine moving module drives the welding head of the welding machine to complete the welding operation of the L-shaped plate and the nut. The L-shaped plate and the nut are mechanically conveyed and fed. Then, the assembly is completed by automated welding. It has high assembly dimensional accuracy and high production efficiency.
