Description

Technical Field

[0001] The utility model relates to the technical field of handle welding, and particularly relates to a handle welding fixture and a flipping platform. Background Art

[0002] A welding wire is a welding material in the form of a metal wire used as a filler metal or simultaneously as a conductive material. In gas welding and tungsten inert gas arc welding, the welding wire is used as a filler metal; in submerged arc welding, electroslag welding, and other gas metal arc welding processes, the welding wire is both a filler metal and a conductive electrode. The surface of the welding wire is not coated with a flux for anti-oxidation.

[0003] In the prior art, it is necessary to manually or use auxiliary equipment to align the crossbar of the handle and the frame of the handle before welding. After welding in the above manner, due to insufficient clamping force between the crossbar of the handle and the frame of the handle, the welding position of the crossbar is prone to deviation, resulting in general or poor welding processing consistency and affecting the quality of the handle finished product. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a handle welding fixture and a flipping platform, improve the welding processing quality and processing consistency of the handle, realize the assembly-line welding of the handle, and improve the processing efficiency of the handle.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a handle welding fixture, which includes a loading platform, a first clamping structure arranged on the loading platform for fixing the handle frame, a second clamping structure for fixing the handle crossbar, and a crossbar welding hole and a frame welding hole opened on the loading platform. The second clamping structure is located inside the handle frame, the first clamping structure is arranged outside the two side frames of the handle frame, the crossbar welding hole is located below the contact position between the handle crossbar and the two side frames of the handle frame, and the frame welding hole is located below the contact position between the two side frames of the handle frame.

[0007] Further, the first clamping structure includes a first fixing column arranged outside the first side frame of the handle frame, a first sliding hole opened on the loading platform, and a first sliding column slidably connected in the first sliding hole. The first sliding column is arranged outside the second side frame of the handle frame to drive the second side frame to approach the first side frame.

[0008] Further, the second clamping structure includes a second fixing column, a second sliding hole opened on the loading platform, a second sliding column slidably connected in the second sliding hole, and a crossbar pushing component arranged on the loading platform. The second sliding column acts on the crossbar pushing component, and a crossbar clamping position is formed between the crossbar pushing component and the second fixing column.

[0009] Further, the crossbar pushing component includes a spring, a third fixed column, a third sliding column, a long dial and a short dial. The connection part of the long dial and the short dial is rotatably connected to the loading platform. The spring is connected between the third fixed column and the third sliding column. The third sliding column is fixedly connected to the end of the long dial. The second sliding column acts on the spring. A crossbar clamping position is formed between the short dial and the second fixed column.

[0010] Further, the crossbar fixing dial includes a long dial and a short dial. The connection part of the long dial and the short dial is rotatably connected to the loading platform. The second sliding column acts on the long dial. A crossbar clamping position is formed between the short dial and the second fixed column.

[0011] Further, it further includes positioning columns arranged on the loading platform for positioning the handle frame.

[0012] Further, it further includes a cylinder for controlling the first clamping structure and the second clamping structure to clamp the handle crossbar and the handle frame. The cylinder is arranged below the loading platform.

Several handle welding fixtures are arranged in an array on the platform base.

[0014] For a handle welding fixture of the present utility model, the first clamping structure is used to fix the handle frame, and the second clamping structure is used to fix the handle crossbar. The first clamping structure squeezes the two frames of the handle frame, so that the two frames of the handle frame are joined. When the two frames of the handle frame are joined, the crossbar is clamped along its length direction. At the same time, the second clamping structure longitudinally clamps the handle crossbar to prevent the handle crossbar from longitudinally shifting. After the first clamping structure and the second clamping structure clamp the handle, the contact positions between the handle crossbar and the two frames of the handle frame and the contact positions of the two frames of the handle frame are respectively located above the crossbar welding hole and the frame welding hole, so as to facilitate the corresponding welding machine to pass through the crossbar welding hole and the frame welding hole to weld the handle crossbar and the handle frame, improving the welding processing quality and processing consistency of the handle.

[0015] For a handle welding fixture flipping platform of the present utility model, after the handle welding fixture clamps the handle, the speed reducer rotates, driving the platform base to flip. Several handle welding fixtures are arranged in an array on the platform base, clamping several handles at a time. During welding, the welding components above the platform base weld the clamped several handles in sequence, thus realizing the assembly line welding of the handles and improving the processing efficiency of the handles.

[0023] As Figures 1 to 3A handle welding fixture as shown includes a loading platform 1, a first clamping structure 2 provided on the loading platform 1 for fixing the handle frame, a second clamping structure 3 for fixing the handle crossbar, and a crossbar welding hole 4 and a frame welding hole 5 opened on the loading platform 1. The second clamping structure 3 is located inside the handle frame, the first clamping structure 2 is arranged outside the two side frames of the handle frame, the crossbar welding hole 4 is located below the contact position between the handle crossbar and the two side frames of the handle frame, and the frame welding hole 5 is located below the contact position between the two side frames of the handle frame. The shape of the handle welded by the utility model is as shown in the figure. When the handle needs to be clamped, the handle frame is placed inside the first clamping structure 2, and the handle crossbar is placed inside the second clamping structure 3. The first clamping structure 2 and the second clamping structure 3 are started. The first clamping structure 2 squeezes the two side frames of the handle frame, making the two side frames of the handle frame meet. When the two side frames of the handle frame meet, the crossbar is clamped along its length direction. At the same time, the second clamping structure 3 longitudinally clamps the handle crossbar to prevent the handle crossbar from having longitudinal deviation. After the first clamping structure 2 and the second clamping structure 3 clamp the handle, the contact positions between the handle crossbar and the two side frames of the handle frame and the contact positions of the two side frames of the handle frame are respectively located above the crossbar welding hole 4 and the frame welding hole 5, so as to facilitate the corresponding welding machine to pass through the crossbar welding hole 4 and the frame welding hole 5 to weld the handle crossbar and the handle frame, improving the welding processing quality and processing consistency of the handle.

[0024] Specifically, as Figure 3 shown, the first clamping structure 2 includes a first fixed column 21 arranged outside the first side frame of the handle frame, a first sliding hole 22 opened on the loading platform 1, and a first sliding column 23 slidably connected in the first sliding hole 22. The first sliding column 23 is arranged outside the second side frame of the handle frame to drive the second side frame to approach the first side frame. When the handle frame is placed inside the first clamping structure 2 and clamping is required, the first sliding column 23 slides inward and interacts with the first fixed column 21 to squeeze the handle side frame.

[0025] Specifically, as Figure 3As shown in the figure, the second clamping structure 3 includes a second fixed column 31, a second sliding hole 32 opened on the loading platform 1, a second sliding column 33 slidably connected in the second sliding hole 32, and a crossbar pushing assembly arranged on the loading platform 1. The second sliding column 33 acts on the crossbar pushing assembly, and a crossbar clamping position is formed between the crossbar pushing assembly and the second fixed column 31. The crossbar pushing assembly includes a spring 341, a third fixed column 342, a third sliding column 343, a long dial 344 and a short dial 345. The connection part of the long dial 344 and the short dial 345 is rotatably connected to the loading platform 1. The spring 341 is connected between the third fixed column 342 and the third sliding column 343. The third sliding column 343 is fixedly connected to the end of the long dial 344. The second sliding column 33 acts on the spring 341, and a crossbar clamping position is formed between the short dial 345 and the second fixed column 31. When the first clamping structure 2 operates, the second sliding column 33 pushes the spring 341. After being pushed by the second sliding column 33, the spring 341 bends, thereby pulling the third sliding column 343 to slide. The third sliding column 343 drives the long dial 344 and the short dial 345 to rotate towards the crossbar. The short dial 345 rotates and pushes the crossbar towards the second fixed column 31 until the crossbar contacts the fixed column and clamps the crossbar.

[0026] Specifically, as Figure 3 shown, it further includes a positioning column 6 arranged on the loading platform 1 for positioning the handle frame. The positioning column 6 is arranged at the middle-upper position and the bottom position of the frame of the handle frame. The positioning column 6 and the first fixed column 21 jointly determine the initial position of the placement of the handle frame.

[0027] Specifically, as Figure 2 shown, it further includes a cylinder 7 for controlling the first clamping structure 2 and the second clamping structure 3 to clamp the handle crossbar and the handle frame. The cylinder 7 is arranged below the loading platform 1. The telescopic end of the cylinder 7 is connected to the first sliding column 23 and the second sliding column 33, and simultaneously pushes the first sliding column 23 and the second sliding column 33.

[0028] The present utility model further provides a handle welding fixture flipping platform, which includes the above-mentioned handle welding fixture, and further includes a support seat 8, a reducer 9, and a platform base 10. One end of the platform base 10 is fixedly connected to the rotating shaft of the reducer 9, and the other end is rotatably connected to the support seat 8. A plurality of handle welding fixtures are arranged in an array on the platform base 10 to clamp a plurality of handles at one time, thereby realizing the assembly line welding of the handles and improving the processing efficiency of the handles; after the handle welding fixture clamps the handle, the reducer 9 rotates, driving the platform base 10 to flip. The welding assembly of the handle is located above the platform base 10, and the welding assembly above the platform base 10 welds the plurality of clamped handles in sequence during welding.

[0029] The above further describes the present utility model by means of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
