Description

Technical Field

[0001] The present application relates to the technical field of multi-spot welding machines, and in particular to a four-station rotary feeding mechanism. Background Art

[0002] A multi-spot welding machine is a mechanical device that uses the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode through the other electrode, an instantaneous heat weld is formed at the two contact resistance points. The welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the workpiece being welded. A feeding mechanism is required when using a multi-spot welding machine.

[0003] After checking the announcement number: CN204135578U, a spot welding machine feeding mechanism is disclosed. This technology discloses "including a bracket, a rotating shaft is rotatably connected to the bracket, a feeding reel is rotatably connected to the rotating shaft, a slide groove is provided on the bracket, the rotating shaft is slidably arranged in the slide groove, the slide groove includes an outlet groove and a feeding groove, and a driving device for driving the rotating shaft to reciprocate between the feeding groove and the outlet groove is provided on one side of the bracket. The utility model has the technical effects of being able to easily install and disassemble the feeding reel";

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing feeding mechanism has a low feeding efficiency, and the feeding mechanism does not have a uniform lifting component. Since the raw material needs to be continuously pushed out of the material frame at a uniform speed when feeding the spot-welded workpiece, there is no uniform lifting component, which makes it inconvenient to feed well and reduces the efficiency of the feeding process; secondly, the existing feeding mechanism does not have a positioning component. Since this feeding mechanism is a four-station feeding mechanism, during the feeding process of one of the stations, a component for positioning the disc is not set, and it is easy for the station on the disc to rotate during feeding, affecting the feeding effect of the feeding mechanism. There is no positioning component, which makes it inconvenient to position the disc and reduces the practicality of the feeding mechanism. Utility Model Content

A first motor 9 is fixedly connected to one side of the bottom end of the connecting plate 8. The output end of the first motor 9 passes through the bottom end of the connecting plate 8 and is fixedly connected to a spindle 6, so that the output end of the first motor 9 drives the spindle 6 to rotate. The top end of the spindle 6 passes through the bottom end of the workbench 1 and is fixedly connected to a disc 4, so that the spindle 6 rotates and drives the disc 4 to rotate. Positioning components 3 used in conjunction with the disc 4 are commonly provided at both ends of the workbench 1. The positioning components 3 serve to facilitate the positioning of the disc 4. Four material frames 5 are fixedly connected to the top of the disc 4. The material frames 5 serve to facilitate the placement of raw materials. A lifting component 2 is commonly provided at the bottom end of the workbench 1 and inside the material frame 5. The lifting component 2 serves to facilitate the uniform feeding of the raw materials.

[0034] Reference Figure 2The jacking assembly 2 includes a mounting plate 23, the top of which is fixedly connected to the bottom of the workbench 1, and one end of the mounting plate 23 is fixedly connected to a second motor 29, which drives the jacking assembly 2. The output end of the second motor 29 passes through one end of the mounting plate 23 and is fixedly connected to a gear 21, so that the output end of the second motor 29 drives the gear 21 to rotate, and the outer surface of the gear 21 is meshedly connected to a rack 27, so that the gear 21 rotates and drives the rack 27 to move. The bottom end of the workbench 1 is fixedly connected to a vertical plate 22, and the bottom end of the vertical plate 22 is fixedly connected to a positioning sleeve 28 used in conjunction with the rack 27. The positioning sleeve 28 facilitates the positioning of the rack 27 when it moves, and one end of the rack 27 is slidably connected to an inner wall of one side of the positioning sleeve 28. The top end of the rack 27 passes through the bottom end of the workbench 1 and the disc 4 in sequence and is in active contact with a moving plate 202, so that the moving plate 202 is lifted up at a uniform speed when the rack 27 moves upward, so that the raw materials are fed evenly.

[0035] Reference Figure 2 The bottom end of the rack 27 is fixedly connected to the limit plate 26, one end of the vertical plate 22 is fixedly connected to the long plate 24, and the lower part of one end of the long plate 24 is fixedly connected to a limit seat 25 used in conjunction with the limit plate 26.

[0038] The implementation principle of the embodiment of the present application is as follows: first, the raw materials to be processed are placed in four material frames 5 in advance, and then the first motor 9 is started. The output end of the first motor 9 drives the main shaft 6 to rotate, and the rotation of the main shaft 6 drives the disc 4 to rotate, so that the material frame 5 on the disc 4 rotates to a suitable feeding position, and then the disc 4 is positioned by the positioning component 3, and then the second motor 29 is started through the lifting component 2. The second motor 29 is a settable motor. The output end of the second motor 29 drives the gear 21 to rotate, and the rotation of the gear 21 drives the rack 27 to move. At the same time, the positioning sleeve 28 plays a role in facilitating the positioning of the rack 27 when it moves. When the rack 27 moves upward, the moving plate 202 is lifted at a uniform speed. At the same time, the guide groove 201 cooperates with the moving plate 202 to guide the moving plate 202 when it moves. The movement of the moving plate 202 allows the raw materials to be fed evenly, thereby improving the utilization efficiency of the feeding mechanism.
