Detailed implementation manners

[0026] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0028] As Figure 1-7 shown in the figure, the present utility model provides a welding machine for lighting fixture decorative parts, including a workbench 100, a welding equipment 200 for welding is fixedly installed on the top of the workbench 100, two brackets 300 are fixedly connected to the top of the workbench 100 and are respectively located on both sides of the welding device, a transmission assembly 400 is arranged between the two brackets 300, and positioning assemblies 500 are respectively installed on the two brackets 300;

[0029] Among them, the positioning component 500 includes a moving screw 501. A positioning block 502 is provided at the bottom end of the moving screw 501. The transmission component 400 is used to drive the moving screw 501 downward and drive the positioning block 502 to contact the lighting fixture decorative part when the welding device 200 is working.

[0030] In this embodiment, a cavity 505 is formed at the bottom end of the moving screw 501. A plurality of chutes 506 are arranged in a circumferential array on the inner wall of the cavity 505. A connecting rod 507 is slidably arranged inside the chute 506. The bottom end of the connecting rod 507 passes through the cavity 505 and is fixedly connected to the top of the positioning block 502. A spring 508 is fixedly arranged between the cavity 505 and the positioning block 502.

[0031] By adopting the above technical solution, under the action of the spring 508, the positioning block 502 has a certain amount of expansion and contraction, which is suitable for positioning lighting fixture decorative parts with different thicknesses and is flexible to use.

[0032] In this embodiment, an anti-slip pad 509 is fixedly connected to the bottom of the positioning block 502. The anti-slip pad 509 is made of elastic rubber material, and the bottom of the anti-slip pad 509 is serrated.

[0033] By adopting the above technical solution, the anti-slip pad 509 plays an anti-slip role, and it can undergo elastic deformation itself. With the serrated setting at the bottom, it can better press the lighting fixture decorative part and will not scratch the surface of the lighting fixture decorative part.

[0034] In this embodiment, the welding device 200 includes a machine body 201. A lifting cylinder 202 is installed on the machine body 201. A welding point 203 is fixedly installed at the movable end of the lifting cylinder 202. The lifting cylinder 202 pushes the welding point 203 to move up and down for welding.

[0035] By adopting the above technical solution, the lifting cylinder 202 pushes the welding point 203 to move up and down to achieve welding.

[0036] In this embodiment, the transmission component 400 includes a rotating shaft 401 rotatably arranged between two brackets 300. A rack 402 is fixedly connected to the front side of the welding point 203. A rotating gear 403 meshing with the rack 402 is fixedly sleeved on the outer wall of the rotating shaft 401. Main bevel gears 404 are fixedly connected to both ends of the rotating shaft 401.

[0037] By adopting the above technical solution, when the lifting cylinder 202 pushes the welding point 203 to move, it drives the rack 402 to move. The cooperation between the rack 402 and the rotating gear 403 causes the rotating gear 403 to drive the rotating shaft 401 to rotate.

[0038] In this embodiment, the two positioning components 500 further include an internally threaded tube 503 rotatably arranged on the bracket 300. The moving screw 501 passes through the internally threaded tube 503 and is threadedly connected therein. A secondary bevel gear 504 meshing with the main bevel gear 404 is fixedly sleeved on the outer wall of the internally threaded tube 503.

[0039] By adopting the above technical solution, the rotating shaft 401 drives the main bevel gear 404 to rotate, and then drives the secondary bevel gear 504 to drive the rotation of the internally threaded tube 503. The internally threaded tube 503 realizes the movement of the moving screw 501 through screw drive.

[0040] In this embodiment, a clamp 301 is fixedly connected to the side of the bracket 300. A limiting rod 5010 is fixedly connected to the top end of the moving screw 501. One end of the limiting rod 5010 away from the moving screw 501 passes through the clamp 301 and is slidably matched with the clamp 301.

[0041] By adopting the above technical solution, when the internally threaded tube 503 realizes the movement of the moving screw 501 through screw drive, the movement is limited by the sliding fit between the limiting rod 5010 and the clamp 301, restricting the tendency of the moving screw 501 to rotate circumferentially, so that the moving screw 501 can only move vertically up and down.

[0042] In this embodiment, a limiting plate 5011 is fixedly connected to one end of the limiting rod 5010 away from the moving screw 501. When the limiting plate 5011 contacts the clamp 301, the bottom end of the moving screw 501 is located below the bottom end of the internally threaded tube 503.

[0043] By adopting the above technical solution, when the moving screw 501 moves upward, the movement is limited by the cooperation between the limiting plate 5011 and the clamp 301, avoiding the separation between the moving screw 501 and the internally threaded tube 503.

[0044] Usage method and working principle of this device:

[0045] When the device is in use, first place the lighting decoration to be welded on the workbench 100, specifically, it can be placed in a receiving mold (not shown). Start the welding equipment 200, and the lifting cylinder 202 drives the welding point 203 to move downward for welding. During the downward movement of the welding point 203, it can drive the rack 402 to move. The rack 402, through cooperation with the rotating gear 403, causes the rotating gear 403 to drive the rotating shaft 401 to rotate. The main bevel gears 404 at both ends of the rotating shaft 401 rotate accordingly and drive the driven bevel gear 504 to rotate. The driven bevel gear 504 drives the internally threaded tube 503 to rotate and, through screw drive, causes the moving screw 501 to move downward. The moving screw 501 drives the positioning block 502 to move into contact with the lighting decoration. As the welding point 203 continues to move downward, the positioning block 502 always contacts the lighting decoration. The distance between the moving screw 501 and the positioning block 502 decreases and compresses the spring 508, causing the elastic force of the spring 508 to act on the positioning block 502. Therefore, during the welding process, the positioning block 502 presses the lighting decoration tightly, preventing the lighting decoration from loosening during welding and causing welding failure. Moreover, it does not require manual operation, reduces safety risks, has a stable process and precise welding, thus improving the welding quality.

[0046] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
