Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and in particular relates to a lamp housing welding device. Background Technology

[0002] The lamp housing is a trumpet-shaped structure that covers the outside of the light source. It not only regulates the light but also provides protection. The lamp housing is formed by bending a fan-shaped plate, then joining the two ends together and welding them together using a welding torch.

[0003] However, since the lamp housing has a trumpet-shaped structure after bending, positioning often relies on manual force applied to both sides to splice the two ends of the fan-shaped plate. This is not only inefficient, but also causes inconsistent gaps at the splicing points of the two ends of the fan-shaped plate due to different force applied each time. Consequently, the weld size is inconsistent during welding, resulting in a large error in the diameter of the lamp housing after welding, which affects subsequent assembly. Furthermore, the lack of limiting components in the axial direction of the lamp housing during welding can easily lead to misalignment at the splicing point, affecting the welding quality. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a lamp housing welding device that automatically limits the outer wall of the lamp housing during welding, ensuring that the joint remains in contact, reducing errors in the formed lamp housing, and improving welding quality.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed: A lamp housing welding device, comprising: The support includes a base, one end of which is vertically provided with a vertical plate, the middle of which is provided with a through hole, and the top of which is provided with a notch that communicates with the through hole. The clamping component includes three sets of clamping assemblies arranged in a circumferential array along the outer periphery of the through hole and a limiting assembly that moves along the length of the base. The clamping assembly includes a support on which a clamping block for clamping the outer wall of the lamp housing is rotatably mounted. A limiting rod is provided on one side of the clamping block. The limiting assembly includes a limiting plate for abutting the large end of the lamp housing. The welding machine includes a vertically arranged lifting rod with a horizontal plate at the top and a welding torch at one end of the horizontal plate, the welding torch corresponding to the top of the notch.

[0006] Furthermore, the clamping block has a C-shaped structure, with its vertical middle section rotatably connected to the support. The C-shaped clamping block is used to abut against the outer wall of the lamp housing, and the limiting rod is located between the connection between the clamping block and the support and the connection between the support and the vertical plate.

[0007] Furthermore, the top surface of the base is provided with a first sliding groove, the length direction of the first sliding groove is consistent with the length direction of the base, the lower end of the limiting plate is provided with a sliding block, the sliding block is slidably connected to the first sliding groove, and the other end of the base is provided with a cylinder, the output end of the cylinder is connected to one side of the sliding block.

[0008] Furthermore, the top surface of the limiting plate is higher than the center of the through hole.

[0009] Furthermore, a second sliding groove is provided on one side of the upright plate, and the length of the second sliding groove is greater than the length of the lamp housing splice. The lower end of the lifting rod is slidably connected to the second sliding groove.

[0010] The beneficial effects of this utility model are as follows: The rotating clamping blocks can be adapted to the inclination of the outer wall busbar of the lamp housing, so that the three clamping blocks form three clamping lines on the outer wall of the lamp housing. Together with the function of the limiting plate, the lamp housing splice is kept in contact during the welding process, while avoiding misalignment at the splice. This not only improves welding efficiency but also ensures welding quality. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-5 As shown, this embodiment provides a lamp housing welding device, including a support 10, a clamping member 20, and a welding machine 30. The support 10 is used to install the clamping member 20 and the welding gun 30. The clamping member 20 is used to clamp the lamp housing 1 and keep the joint of the lamp housing 1 in contact during the welding process. The welding gun 30 is used to weld the joint of the lamp housing 1.

[0020] Specifically, such as Figure 1 , Figure 5 As shown, the support member 10 includes a base 11 and an upright plate 12. The base 11 is fixedly connected to a frame or to the ground, and its length dimension is greater than its width dimension. A first groove 111 is provided on the long axis of the top surface of the base 11, and the length direction of the first groove 111 is consistent with the length direction of the base 11. The upright plate 12 is vertically arranged and is perpendicularly connected to one end of the top surface of the base 11. A second groove 112 parallel to the long axis of the base 11 is provided on one side of the upright plate 12. The length of the end of the second groove 112 away from the direction of the first groove 111 extends beyond the position of the upright plate 12 on the base 10. A through hole 121 is provided at the upper end of the upright plate 12, and the axis of the through hole 121 is parallel to the axis of the base 11. A notch 122 is recessed downward in the middle of the top surface of the upright plate 12, and the lower end of the notch 122 communicates with the through hole 121.

[0021] like Figures 1-3 The clamping component 20 shown includes a clamping assembly 21 and a limiting assembly 22. The clamping assembly 21 is provided in three sets. The three sets of clamping assemblies 21 are arranged in a circular array along the outer periphery of the through hole 121. The clamping assembly 21 is vertically disposed on the side of the upright plate 12 facing the other end of the base 11. One clamping assembly 21 corresponds to the side directly below the notch groove 122, and the other two clamping assemblies 21 are respectively located on both sides below the notch groove 122.

[0022] The clamping assembly 21 includes a support 211, a clamping block 212, and a limiting rod 213. The support 211 includes two parallel and spaced-apart support plates. The clamping block 212 has a C-shaped structure, with a rotating pin passing through the middle section of its vertical part. The two ends of the rotating pin are rotatably connected to the corresponding support plates. The opening of the C-shaped clamping block 212 faces the axial direction of the through hole 121. The two end arms of the clamping block 212 are used to limit the outer wall of the lamp housing 1. The limiting rod 213 is located on the side of the rotating pin facing the connection between the support 211 and the vertical plate 12. The two ends of the limiting rod 213 are distributed on the connection of the support plates. The limiting rod 213 is used to limit the outer wall of the clamping block 212 so that the clamping block 212 maintains stability when limiting the lamp housing 1.

[0023] The limiting assembly 22 includes a limiting plate 221, a slide block 222, and a cylinder 223. The lower end of the slide block 222 is slidably connected to the first slide groove 111. The limiting plate 221 is vertically disposed on the upper end of the slide block 222, and the distance between the top surface of the limiting plate 221 and the top surface of the base 11 is greater than the distance between the center of the through hole 121 and the top surface of the base 11. This allows the limiting plate 221 to abut against the larger end of the lamp housing 1 during welding, which not only limits the axial movement of the lamp housing 1 but also ensures that the end of the lamp housing 1 facing the larger end is flush, preventing misalignment at the joint and thus improving welding accuracy. The cylinder 223 is disposed on the top surface of the end of the base 11 away from the vertical plate 12. The cylinder 223 is arranged along the length of the base 11, and its output end is perpendicularly connected to the side of the slide block 222 away from the vertical plate 12.

[0024] like Figure 1 , Figure 4 As shown, the welding 30 includes a lifting rod 31, a horizontal plate 32, and a welding torch 33. The lifting rod 31 is set vertically to accommodate the inclination of the inclined line formed at the splicing point of the lamp housing 1. Its lower end is slidably connected to the second sliding groove 112. One end of the horizontal plate 32 is set vertically on the top surface of the lifting rod 32, and the other end of the horizontal plate 32 extends into the upper part of the base 11. The welding torch 33 is set below the other end of the horizontal plate 32, and the output end of the welding torch 33 is perpendicular to the direction of the axis of the through hole 121.

[0025] Specific operating procedures: Insert the small end of the bent lamp housing 1 into the through hole 121 along the direction of the first sliding groove 111 toward the direction of the upright plate 12, with the splice facing upwards. Make the end of the clamping block 212 facing the through hole 121 abut against the outer wall of the small end of the lamp housing 1, and the end of the clamping block 212 facing the limiting plate 221 abut against the outer wall of the large end of the lamp housing. Activate the cylinder 223 to push the slide block 222 toward the large end of the lamp housing 1 until the limiting plate 221 abuts against the end face of the large end of the lamp housing 1. The lamp housing 1 is then completely limited, and the outer wall of the end of the clamping block 212 facing the upright plate 12 is limited by the limiting rod 213 to keep the clamping block 212 stable during the clamping process.

[0026] Start the lifting rod 31, and move the welding gun 33 vertically downward to one end of the lamp housing 1 splice. Then start the welding gun 33 and simultaneously move the lifting rod 31 along the second slide 112 toward one end of the first slide 111 to the other end. During the movement, lower the lifting rod 31 so that the welding gun 33 can maintain welding at the lamp housing 1 splice.

[0027] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
