Description

Technical Field

[0001] This application relates to the field of welding processing technology, and in particular to a rotary worktable for welding. Background Technology

[0002] Existing welding processes for motor housings or molecular pump housings typically involve placing the workpiece on a workbench, with the worker holding a welding torch in one hand and a protective mask in the other. When welding the curved circumference of the workpiece's housing, after completing one weld, the worker must put down the welding torch and mask, manually adjust the workpiece's angle, and then pick up the tools again to weld the next position. This process is repeated until all welded areas on the workpiece are completed. This traditional welding method is still widely used in many factories and is a relatively standard operating procedure.

[0003] However, in the traditional welding process, each adjustment of the workpiece's placement angle relies on manual movement by the worker. This not only increases the worker's labor intensity but also leads to frequent interruptions in the welding process, greatly reducing welding efficiency. Therefore, further improvements are needed. Utility Model Content

[0004] To improve the welding efficiency of workpieces, this application provides a rotary worktable for welding.

[0005] The rotary worktable for welding provided in this application adopts the following technical solution: A rotary welding worktable includes a worktable plate, on which a turntable for placing workpieces is rotatably connected. The worktable plate is provided with a rotating assembly that drives the turntable to rotate around its own axis. A vertical rod is provided on the turntable, and a limiting seat is slidably connected to the vertical rod along the vertical direction. The limiting seat is provided with a pressure rod that abuts against the upper end face of the workpiece. Multiple pressure rods are provided and distributed around the axis of the limiting seat. The vertical rod is provided with a first adjusting assembly that adjusts the lifting and sliding movement of the limiting seat.

[0006] By adopting the above technical solution, after the workpiece is placed on the turntable, the first adjustment component drives the limit seat to move down, so that the pressure rod on the limit seat abuts against the upper end face of the workpiece, thereby pressing the workpiece. When the angle of the workpiece needs to be adjusted, the rotating component drives the turntable to rotate, thereby rotating the workpiece, avoiding manual adjustment of the workpiece angle and improving welding efficiency.

[0007] Preferably, the vertical rod is a threaded rod, and the limiting seat is coaxially provided with a through hole for the vertical rod to pass through. The first adjusting component includes an upper nut threaded to the vertical rod and located above the limiting seat, and a lower nut threaded to the vertical rod and located below the limiting seat. The upper nut abuts against the upper end face of the limiting seat, and the lower nut abuts against the lower end face of the limiting seat.

[0008] By adopting the above technical solution, the vertical rod is set as a threaded rod, and the upper and lower nuts abut against the upper and lower end faces of the limiting seat, so as to easily adjust the lifting and sliding of the limiting seat on the vertical rod to adapt to workpieces of different heights.

[0009] Preferably, the outer peripheral wall of the limiting seat has a notch that communicates with the through hole for the vertical rod to slide through, and the notch is located between two adjacent pressure rods.

[0010] By adopting the above technical solution, a notch with a through hole is opened on the outer peripheral wall of the limiting seat, and the notch is located between two adjacent pressure rods, which facilitates the installation of the limiting seat through the vertical rod, and also facilitates the installation and disassembly of the limiting seat.

[0011] Preferably, the upper end face of the turntable is coaxially provided with a recessed groove, and a rotating shaft is coaxially fixedly inserted through the turntable. The upper end of the rotating shaft extends into the recessed groove and is rotatably inserted through the worktable. The upper end face of the rotating shaft is coaxially provided with a sliding hole, and a vertical rod is slidably inserted into the sliding hole. The rotating shaft is provided with a second adjustment component for adjusting the sliding position of the vertical rod.

[0012] By adopting the above technical solution, the groove on the turntable can better place the workpiece, and the vertical rod can slide in the sliding hole of the rotating shaft. With the help of the second adjustment component, the sliding position of the vertical rod can be adjusted to adapt to workpieces of different heights.

[0013] Preferably, the vertical rod is a threaded rod, and the second adjusting component is a threaded sleeve coaxially fixed to the upper end of the rotating shaft, with the lower part of the vertical rod threaded through the threaded sleeve.

[0014] By adopting the above technical solution, the feed amount of the vertical rod relative to the screw sleeve can be adjusted by rotating the vertical rod, thereby fine-tuning the height of the adjusting vertical rod and thus adjusting the height of the limit seat.

[0015] Preferably, the lower end face of the workbench is fixedly connected to a bracket, and the rotating assembly includes a rotary motor fixedly connected to the bracket, a drive gear coaxially fixedly sleeved on the output shaft of the rotary motor, and a driven gear coaxially fixedly sleeved on the lower part of the rotating shaft, with the drive gear meshing with the driven gear.

[0016] By adopting the above technical solution, the rotary motor is fixed on the bracket, and the rotary motor drives the driving gear to rotate. The driving gear meshes with the driven gear, thereby driving the driven gear fixed coaxially at the lower part of the rotating shaft to rotate, so that the rotating shaft and the turntable connected to it rotate, realizing the automatic drive of the turntable to rotate around its own axis.

[0017] Preferably, the bracket includes a top plate fixedly connected to the lower end face of the workbench, a pair of side plates fixedly connected to both sides of the top plate, and a support plate located below the top plate and connected between the two side plates. The lower part of the rotating shaft rotatably passes through the top plate, and the rotating motor is fixedly connected to the support plate.

[0018] Preferably, the side plate has a groove, the length of which is vertical, and the side plate has a fixing bolt that passes through the groove and is threaded to the support plate, with the end face of the fixing bolt abutting against the outer wall of the side plate.

[0019] By adopting the above technical solution, the vertical position of the support plate on the side plate can be flexibly adjusted, making it easy to adjust the height of the rotary motor according to actual needs, so that the driving gear and the driven gear are in a meshing state.

[0020] In summary, this utility model has the following beneficial effects: 1. After the workpiece is placed on the turntable, the first adjustment component drives the limit seat to move down, so that the pressure rod on the limit seat abuts against the upper end face of the workpiece, thereby pressing the workpiece. When the angle of the workpiece needs to be adjusted, the turntable is driven to rotate by the rotation component, which drives the workpiece to rotate, avoiding manual adjustment of the workpiece angle and improving welding efficiency. 2. The feed amount of the vertical rod relative to the screw sleeve can be adjusted by rotating the vertical rod, thereby fine-tuning the height of the adjusting vertical rod and thus adjusting the height of the limit seat.

The side plates 122 are provided with fixing bolts 125 that pass through the sliding groove 124 and are threaded to the support plate 123. The end face of the fixing bolt 125 abuts against the outer side wall of the side plate 122.

[0026] The support plate 123 is provided with a rotating assembly 13 that drives the turntable 2 to rotate around its own axis. Specifically, the lower end of the rotating shaft 3 is coaxially fixedly connected to a connecting rod 31. The rotating assembly 13 includes a rotary motor 131 fixedly connected to the lower end face of the support plate 123, a drive gear 132 coaxially fixedly sleeved on the output shaft of the rotary motor 131, and a driven gear 133 coaxially fixedly sleeved on the connecting rod 31 and located between the support plate 123 and the top plate 121. The output shaft of the rotary motor 131 rotatably passes through the support plate 123, and the drive gear 132 meshes with the driven gear 133. The rotary motor 131 is a servo motor, and the rotary motor 131 is electrically connected to a control switch. In this embodiment, the control switch is a foot switch.

[0027] Reference Figure 2 , Figure 4 The upper end face of the rotating shaft 3 is coaxially provided with a sliding hole 32. The rotating shaft 3 is provided with a vertical rod 4 that is coaxially slidably inserted into the sliding hole 32.

Specifically, the limiting seat 42 has a through hole coaxially provided for the vertical rod 4 to pass through. The limiting seat 42 is provided with a pressure rod 43 that abuts against the upper end face of the workpiece.

[0029] The implementation principle of a welding rotary worktable according to an embodiment of this application is as follows: After the workpiece is placed on the turntable 2, the height of the limiting seat 42 is first roughly adjusted by rotating the upper nut 441 and the lower nut 442. Then, the upper nut 441 and the lower nut 442 are tightened so that the upper nut 441 abuts against the upper end face of the limiting seat 42 and the lower nut 442 abuts against the lower end face of the limiting seat 42 to clamp the limiting seat 42. Then, the vertical rod 4 is rotated by the handle 41 to move the vertical rod 4 down as a whole for fine adjustment, so that the pressure rod 43 on the limiting seat 42 abuts against the upper end face of the workpiece, thereby pressing the workpiece. During the welding process, when the angle of the workpiece needs to be adjusted, the worker starts the rotary motor 131 by the foot switch and drives the turntable 2 to rotate through the driving gear 132 and the driven gear 133, thereby driving the workpiece to rotate, avoiding manual adjustment of the workpiece angle and improving welding efficiency.
