Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to a welding device for a bed plate frame of a moxibustion therapy bed. Background Art

[0002] Moxibustion therapy bed is a professional bed used for moxibustion therapy, usually used in Chinese medicine therapy, massage and acupressure, etc. When producing the bed frame of moxibustion therapy bed, in order to enhance the stability of the bed and meet the needs of aesthetics and safety, the bed frame is usually welded.

[0003] When welding the bed board frame, some manufacturers will first manually splice the bed board frame components, and then press and weld the spliced ​​bed board frame. However, manually splicing the bed board frame will consume a long time and have low work efficiency. Therefore, some manufacturers will use positioning devices to splice components to improve efficiency. Refer to the Chinese patent application document with publication number CN114671610A, entitled Bed Frame Positioning Device and Welding Method. In the patent application document, during the working process, the outer frame is first placed on the main positioning block and the auxiliary positioning block, and the main positioning groove on the main positioning block and the auxiliary positioning groove on the auxiliary positioning block support and limit the outer frame. Then the grid assembly is placed on the support plate and the limiting block passes through the grid assembly of the bed frame assembly, so that the grid assembly of the bed frame assembly is positioned and the bed frame assembly is positioned as a whole. Then, the sliding mechanism is controlled by the external control system switch to transfer the bed frame assembly to the welding area of ​​the welding mechanism. The pre-stressing part first realizes sufficient pre-stressing between the grid assembly of the bed frame assembly and the outer frame. Secondly, under the action of the welding telescopic part, the welding head of the welding mechanism correspondingly abuts against the left welding point area and the right welding point area of ​​the bed frame assembly to realize symmetrical welding on both sides of the bed frame assembly.

[0004] Referring to the above technical solution, the positioning device in the above solution cannot position the bed board frame composed of transverse rods and longitudinal rods, and workers are required to manually splice and press the transverse rods and longitudinal rods, which is labor-intensive, time-consuming and inefficient. Summary of the invention

[0005] In order to solve the technical problems of lack of positioning fixtures, high labor intensity and low work efficiency due to manual splicing, the present application provides a welding device for the bed board frame of a moxibustion therapy bed.

[0006] The present application provides a welding device for a bed plate frame of a moxibustion therapy bed, which adopts the following technical scheme: a welding device for a bed plate frame of a moxibustion therapy bed, comprising a frame, a workbench rotatably arranged on the frame, and a mechanical arm for welding, wherein the mechanical arm is located on one side of the workbench, and two workstations are symmetrically arranged on the workbench, the workstation away from the side of the mechanical arm is a loading station, and the workstation close to the side of the mechanical arm is a welding station, each of which is provided with a pair of transverse loading ports and four longitudinal loading ports, the pair of transverse loading ports and the four longitudinal loading ports are used for loading transverse rods and longitudinal rods of the bed plate frame, and first limit plates are arranged on the outer sides of the four longitudinal loading ports A second limit plate is provided at both ends of a pair of horizontal feeding ports, a first tightening mechanism is provided on the inner sides of the four longitudinal feeding ports, and multiple second tightening mechanisms are provided on the outer sides of the pair of horizontal feeding ports, and the first tightening mechanism and the second tightening mechanism cooperate to splice the horizontal rod and the longitudinal rod into a complete bed board frame; a placement rack is provided below the loading station through track movement, and six placement bins for storing horizontal rods or longitudinal rods are provided on the placement rack, and the six placement bins correspond one by one to a pair of horizontal feeding ports and four longitudinal feeding ports of the loading station, and a loading plate is provided on a common vertical sliding sleeve on the six placement bins, and a lifting mechanism for driving the loading plate to rise and fall is provided at the bottom of the placement rack.

[0007] By adopting the above technical solution, when the bed board frame needs to be welded, the lifting mechanism first drives the loading plate to move, and the loading plate pushes the transverse rod and the longitudinal rod through the transverse loading port and the longitudinal loading port to the top of the workbench. The transverse rod and the longitudinal rod can be directly loaded through the movement of the loading plate, which reduces manual operation and reduces work intensity. Then the first tightening mechanism pushes the longitudinal rod to move, and the second tightening mechanism pushes the transverse rod to move. The longitudinal rod first presses against the first limit plate, and then the second tightening mechanism pushes the transverse rod to be pressed on the longitudinal rod. At this time, the bed board frame is spliced ​​and pressed.

[0008] After completing the splicing and pressing of the bed board frame, the lifting mechanism first drives the loading plate to move downward, and the downward movement of the loading plate drives the transverse rods and longitudinal rods in the placement bin to move downward. The transverse rods and longitudinal rods are driven downward by the lifting mechanism, thereby reducing the risk of interference between the transverse rods and longitudinal rods and the workbench. Then the rotation source drives the workbench to rotate, so that the bed board frame that has completed the splicing and pressing is rotated to the welding station, and the robotic arm welds the bed board frame. At the same time, the bed board frame that has completed welding is rotated to the loading station, and the second tightening mechanism first cancels the tightening of the transverse rods, and the transverse rods cancel the tightening of the longitudinal rods. The first tightening mechanism then cancels the tightening of the longitudinal rods, and the welded bed board frame is removed. After that, the loading plate continues to move to transport the transverse rods and longitudinal rods, and the first tightening mechanism and the second tightening mechanism continue to push and press the transverse rods and longitudinal rods.

[0009] By pressing the end of the longitudinal rod with the transverse rod, the longitudinal rod can limit the position of the transverse rod, thereby improving the fitting effect between the longitudinal rod and the transverse rod, which is beneficial to improving the welding effect, and facilitating the clamping of longitudinal rods of different lengths, which is beneficial to improving the versatility of the welding device.

The entire process does not require manual operation, which is conducive to saving manpower and reducing labor intensity. In addition, the present application can complete the disassembly of the welded bed board frame and the positioning and clamping of the bed board frame to be welded during the welding process, thereby further improving work efficiency.

[0040] Among them, refer to Figure 2 and Figure 3 Each workstation is provided with a pair of movable frames 35, which are slidably connected to the frame 1. Each movable frame 35 is composed of a pair of transverse connecting rods and two longitudinal connecting rods. The two longitudinal connecting rods are correspondingly arranged on the inner side of the longitudinal feeding port 23. A support block 32 is connected to a longitudinal connecting rod. Two linear actuators are arranged at the middle position of each workstation of the workbench 2. The telescopic ends of the two linear actuators are arranged back to back. Each linear actuator is fixedly connected to a movable frame 35, and this linear actuator can be a cylinder.

[0041] When the longitudinal rod needs to be compressed, the cylinder drives the movable frame 35 to move, and the movement of the movable frame 35 drives the support block 32, the first return spring 34 and the first push plate 31 to move. The first push plate 31 pushes the longitudinal rod, and then the longitudinal rod abuts against the first limit plate 25.

The two ends of the rope 452 are respectively fixedly connected to the end of the moving frame 35 and the side wall of the second push plate 41 close to the fixed plate 42. Before the second push plate 41 pushes the transverse rod to press the longitudinal rod, the longitudinal rod is first pressed against the first limit plate 25 by the first push plate 31.

[0046] The guide roller 451 can guide the movement of the rope 452 .

[0047] Reference Figure 5 and Figure 7 , a welding device for a moxibustion therapy bed frame also includes a clamping mechanism 7. The clamping mechanism 7 is arranged on the frame 1, and the clamping mechanism 7 is used to clamp the placement rack 5 on the frame 1.

[0048] Reference Figure 7 The clamping mechanism 7 includes a clamping block 13, a mounting seat 71, a moving seat 72, a pressure roller 721 and a third return spring 73. The clamping block 13 is fixedly connected to the frame 1, the mounting seat 71 is provided with a pair of mounting seats 71 respectively arranged at the upper and lower positions of the clamping block 13, the pair of mounting seats 71 are respectively fixedly connected to the frame 1 and the placement frame 5, each mounting seat 71 is vertically provided with a guide groove 711, the moving seat 72 is provided with a pair, each moving seat 72 is slidably connected to the guide groove 711 of a mounting seat 71, a pair of pressure rollers 721 are provided, each pressure roller 721 is rotatably connected to a moving seat 72, the third return spring 73 is arranged between the mounting seat 71 and the moving seat 72, the moving seat 72 is fixedly connected with a third guide rod, the end of the third guide rod away from the moving seat 72 is slidably connected to the mounting seat 71, and the third return spring 73 is sleeved on the third mounting seat 71.

[0049] When the placement rack 5 needs to cooperate with the frame 1, the placement rack 5 is pushed, and the placement rack 5 moves along the track 12, and then the clamping block 13 enters between the two pressure rollers 721 and is clamped under the action of the restoring force of the third reset spring 73; through the setting of the pressure roller 721 and the third reset spring 73, the placement rack 5 and the frame 1 can be positioned quickly and conveniently, and the operation is convenient.

[0050] The implementation principle of the welding device for the bed plate frame of a moxibustion therapy bed in the embodiment of the present application is as follows: When it is necessary to weld the bed frame, first, the telescopic end of the linear actuator installed on the placement frame 5 moves upward to drive the loading plate 52 to move upward. The loading plate 52 moves upward to push the transverse rod and the longitudinal rod. The transverse rod and the longitudinal rod are moved to the top of the workbench 2 through the transverse loading port 24 and the longitudinal loading port 23 respectively. Then, the telescopic end of the linear actuator on the workbench 2 extends and drives the moving frame 35, the support block 32 and the rope 452 to move. The movement of the support block 32 drives the first push plate 31 to move. The first push plate 31 moves The longitudinal rod is pushed to move, and at the same time, the rope 452 moves so that the second push plate 41 can push the transverse rod to slide along the second limit plate 26 under the action of the restoring force of the second return spring 44, and then the longitudinal rod abuts against the first limit plate 25, and the movable frame 35 and the support block 32 continue to move. The movement of the support block 32 compresses the first return spring 34, and the first push plate 31 presses the longitudinal rod. Subsequently, the transverse rod presses the longitudinal rod under the action of the restoring force of the second return spring 44, and the transverse rod remains in a compressed state, and the bed board frame is spliced.

[0051] After the splicing is completed, the telescopic end of the linear drive installed on the placement frame 5 moves downward and drives the loading plate 52 to move downward. The loading plate 52 moves downward to drive the transverse rod and the longitudinal rod to move out of the transverse loading port 24 and the longitudinal loading port 23. Then the workbench 2 rotates. The rotation of the workbench 2 drives the spliced ​​bed board frame to move to the welding station 22. The welded bed board frame moves to the loading station 21. Then the robot arm 11 welds the bed board frame.

[0052] When the welded bed frame moves to the loading station 21, the telescopic end of the linear drive located on the workbench 2 contracts to drive the moving frame 35, the support block 32 and the rope 452 to move, and the pressure of the first return spring 34 gradually decreases. At the same time, the rope 452 moves to drive the second push plate 41 to move and compress the second return spring 44. The second push plate 41 cancels the pressure on the transverse rod, and then the telescopic end of the linear drive located on the workbench 2 continues to contract to drive the moving frame 35, the support block 32 and the rope 452 to move. The first push plate 31 cancels the contact with the longitudinal rod, and the welded bed frame is removed. Then, the telescopic end of the linear drive installed on the placement frame 5 moves upward and drives the loading plate 52 to move upward. The loading plate 52 moves upward and drives the transverse rod and the longitudinal rod to return to the initial positions in the transverse loading port 24 and the longitudinal loading port 23.

[0053] Example 2 The second tightening mechanism 4 can also adopt another structure, the difference is: instead of adopting a structure in which the movable frame 35 and the second push plate 41 are connected by a pull rope assembly 45, a linear driver is used to directly drive the second guide rod 43 to move linearly.

[0054] Example 3 Another structure can be used to drive the support block 32 to move. The difference is that instead of using a structure in which the moving frame 35 drives the two support blocks 32 at one end to move, a linear driver is used to directly drive one support block 32 to move linearly.

[0055] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
