Description

Technical Field

[0001] The utility model belongs to the technical field of thermos cup welding machines and relates to a four-station universal-mouth automatic welding machine. Background Art

[0002] A welding machine is a device used to weld objects. Because the thermos cup has an inner liner and an outer liner, the thermos cup must undergo a welding process. And because the shape of the thermos cup is round, generally speaking, the welding end of the welding gun only needs to be aligned with the edge of the inner liner and the outer liner, and then the thermos cup is rotated to complete the welding process. Therefore, the workpiece is generally switched to a welding point as the spindle rotates.

[0003] At present, the functionality of the thermos cup welding machines on the market is limited. They do not have working functions such as pressing round bottoms and arc bottoms. They can usually only weld one type of thermos cups, and the working efficiency of the welding machine at a single workstation is still very low. Utility Model Content

DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figures 1 to 3 As shown, four workstation groups aligned vertically are formed between the bottom bracket 1 and the top bracket 2, and each workstation group has welding components. Four workstation groups aligned vertically are formed between the bottom bracket 1 and the top bracket 2, and each workstation group has welding components. The welding components include an upper spindle 4, a lower spindle 5, an upper shaft driving component 6, a lower shaft driving component 7, and a pressing component. The upper spindle 4 and the lower spindle 5 are respectively detachably provided with an upper mold 8 and a lower mold 9. The upper mold 8 and the lower mold 9 are connected to the thermos cup workpiece to form a processing station.

[0019] The profiling components include a profiling bracket 10 fixedly arranged on the top bracket 2 and having a lifting track, a lifting platform 11 lifted and lowered in the lifting track and having a horizontal slide rail, a profiling rod 12 slidably arranged on the horizontal slide rail, a profiling cylinder 13 fixed on the lifting platform 11 and having an output end fixed to one end of the profiling rod 12, and a profiling wheel 14 fixed at the outer end, and the profiling wheel 14 is oriented from the side toward the processing station.

[0020] An adjusting screw 15 is vertically arranged on the profile bracket 10 , and an adjusting screw hole is arranged on the lifting platform 11 . The adjusting screw 15 cooperates with the adjusting screw hole, and the height of the lifting platform 11 relative to the profile bracket 10 can be adjusted by rotating the adjusting screw 15 .

[0021] A locking screw hole is opened laterally on the profiled bracket 10, in which a locking screw is rotatably arranged. A wrench 16 is arranged at the outer end of the locking screw. By adjusting the locking screw, the end of the locking screw and the adjusting screw 15 are squeezed or relaxed.

[0022] The pressing wheel 14 can be freely replaced according to the cup shape requirements. After designing this pressing wheel 14, if the inner and outer liner of the thermos cup need to be welded, they can be pressed from the side, and the pressing pressure is provided by the pressing cylinder 13. When in use, the pressing cylinder 13 will always provide pressure to the pressing rod 12 to ensure that the pressing wheel 14 at the end of the pressing rod 12 can be firmly attached to the side of the thermos cup workpiece.

[0023] Because different thermos cups have different heights, the molding wheel 14 also needs to have height adjustment capabilities. This device uses the rotation of the adjusting screw 15 to drive the lifting platform 11 to move up and down relative to the molding bracket 10. Before moving, the wrench 16 needs to be rotated to loosen the locking screw. After the movement is completed, the wrench 16 needs to be rotated to lock the locking screw.

[0024] The upper shaft driving component 6 includes an upper shaft driving motor arranged on the top bracket 2, an upper shaft driving wheel fixedly mounted on the output end of the upper shaft driving motor, an upper shaft driven wheel mounted on the upper main shaft 4 through a keyway and a key bar docking form, and an upper shaft conveyor belt tightly mounted between the upper shaft driving wheel and the upper shaft driven wheel.

[0025] The lower shaft driving component 7 includes a lower shaft driving motor arranged on the bottom bracket 1, a lower shaft driving wheel fixedly mounted on the output end of the lower shaft driving motor, a lower shaft driven wheel fixedly mounted on the lower main shaft 5, and an upper shaft conveyor belt tightly mounted between the lower shaft driving wheel and the lower shaft driven wheel.

[0026] A lifting plate 17 is provided on the upper bracket for lifting, and the upper shaft driving motor is fixed on the lifting plate 17. A compensation driving motor 18 and a fixed body 19 are fixed on the top bracket 2. A compensation screw hole is vertically penetrated in the fixed body 19, and a compensation screw 20 is rotatably provided on the compensation screw hole. The compensation screw 20 is driven to rotate by the upper shaft driving motor. During the rotation process, the compensation screw 20 realizes lifting and lowering movement due to the existence of the compensation screw hole, and the bottom of the compensation screw 20 is rotatably docked with the bottom of the upper main shaft 4 (that is, they can be lifted and lowered synchronously by docking together, but they are independent of each other and do not interfere with each other during the rotation process).

[0027] Because different types of thermos cups have different heights, after replacing the upper mold 8 and the lower mold 9, it is also necessary to readjust the maximum moving range of the upper spindle 4 and the lower spindle 5 so that the upper mold 8 and the lower mold 9 can be completely consistent with the height of the thermos cup workpiece. Therefore, this equipment uses a compensation drive motor 18, a compensation screw 20, and a compensation screw hole to realize the height position adjustment of the upper spindle 4 relative to the upper bracket.

[0029] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
