Description

Technical Field

[0001] This utility model relates to the field of massage chair processing equipment, and in particular to a welding device for massaging chair processing. Background Technology

[0002] Massage chair frame structures often include curved rod-like components, especially large curved support parts. Welding of these components has traditionally relied on manual labor or general-purpose welding equipment. Manual welding suffers from high labor intensity, inconsistent weld quality, and low efficiency. General-purpose welding equipment often struggles to meet the clamping and positioning requirements of the specific curved workpieces in massage chairs, particularly during circumferential welding. This requires stable support, precise rotation, and flexible, multi-angle adjustment of the welding torch. Existing equipment cannot simultaneously meet these requirements, resulting in low welding precision, poor weld consistency, and negatively impacting the overall structural strength and appearance of the massage chair. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a welding device for processing massage chairs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A welding device for processing massage chairs includes a first side support, a second side support, and a connecting top beam for connecting the two. A guide rod is provided at the top inner side of the connecting top beam, and a ball screw is provided below the guide rod. The outward-facing side of the ball screw is connected to a first motor. A slider is movably mounted on the ball screw, and a fixing block is provided below the slider. A hemispherical groove is provided at the bottom of the fixing block, and a rotating ball is movably mounted inside the hemispherical groove. The outer surface of the rotating ball is fixedly connected to one end of a sleeve. A connecting rod is movably mounted inside the sleeve, and a welding gun is fixedly connected to the other end of the connecting rod. An inverted U-shaped lifting rod is provided at the top of the slider, and the lifting rod is suspended from the guide rod.

[0006] The first side bracket and the second side bracket are provided with a support platform in the center, and the support platform is set in an upward open semi-circular shape;

[0007] The support platform has symmetrical extension barrels on both sides. A rotating shaft is provided on the outward side of the extension barrel. A first pulley is sleeved on the rotating shaft. The first pulley and the second pulley are connected by a belt. The second pulley is installed at the output shaft end of the second motor.

[0008] One side of the extension barrel facing the support table is detachably assembled with a limit ring, and one end of the extension barrel facing the limit ring is hollow. The limit ring is a circular hollow structure, and a threaded sleeve is fixedly installed circumferentially on the limit ring. There are at least three threaded sleeves. During assembly, a screw is screwed into the threaded sleeve, and the workpiece to be welded is fixed in the middle by screwing in the screw.

[0009] Preferably, the connecting top beam is in a shape similar to "冂" and wraps above the first side bracket and the second side bracket. Specifically, it is in a 冂 shape externally, but the two side edges face inward and are fixedly connected to the first side bracket and the second side bracket respectively.

[0010] Preferably, the first motor is fixedly installed at the outer end of the connecting top beam.

[0011] Preferably, a welding control switch and a motor control switch are arranged on the handle of the welding torch. The welding control switch and the motor control switch are electrically connected to an external power supply. It should be noted that there is an external power supply in this solution, but it is not drawn in the figure, and all structures that need to be electrically connected are externally electrically connected to the external power supply.

[0012] Preferably, the bottom of the support table is supported by a support frame, and the top of the support table is evenly provided with balls to facilitate the rotation of the workpiece to be welded.

[0013] Preferably, the two extension barrels are respectively arranged on the first side bracket and the second side bracket, and there are also two second motors, which are respectively arranged on the outer sides of the first side bracket and the second side bracket facing outward, facilitating the rotary welding of the workpieces to be welded on the corresponding two sides.

[0014] Preferably, one side of the extension barrel facing the limit ring is provided with a step, and through holes are provided at the edge of the step. The positions of the through holes are the same as the positions of the mounting holes of the limit ring. During assembly, an external bolt passes through the through hole and the mounting hole to lock the extension barrel and the limit ring into one body.

[0015] Preferably, an anti-slip pad made of rubber material is arranged at the contact end on the inner side of the screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This welding equipment achieves stable linear movement of the welding torch by connecting the guide rod and ball screw on the top beam in conjunction with the slider. The connection between the fixed block below the slider, the rotating ball, and the sleeve allows for flexible adjustment of the welding torch at multiple angles. The lifting rod ensures smooth operation of the slider. The central upward-opening semi-circular support platform, in conjunction with its top ball bearing, effectively supports the arc-shaped workpiece and reduces movement resistance. The extension barrels on both sides of the support platform are driven by a second motor through pulleys to rotate the workpiece on the support platform. The detachable limiting rings at the ends of the extension barrels can quickly and firmly clamp the middle of workpieces of different sizes through circumferentially distributed threaded sleeves and screws. This equipment integrates the precise translation and angle adjustment of the welding torch, the stable support and automatic rotation of the workpiece, and the quick clamping function, significantly improving the welding accuracy, weld uniformity, and production efficiency of the arc-shaped workpieces for massage chairs, while reducing the labor intensity of workers.

Detailed Implementation

[0022] Reference Figures 1-4 A welding device for processing massage chairs includes a first side support 1, a second side support 2, and a connecting top beam 3 for connecting the two. See details. Figure 1 and 2, the connecting top beam 3 is in a shape like "冂" and wraps above the first side bracket 1 and the second side bracket 2. A guide rod 31 is provided at the inner top of the connecting top beam 3. A ball screw 41 is provided below the guide rod 31. The outer side of the ball screw 41 is connected to the first motor 4. During installation, the first motor 4 is fixedly installed at the outer end of the connecting top beam 3. A slider 32 is movably installed on the ball screw 41. A fixing block 33 is provided below the slider 32. A hemispherical groove is provided at the bottom of the fixing block 33. A rotating ball 35 is movably installed inside the hemispherical groove. The outer surface of the rotating ball 35 is fixedly connected to one end of a sleeve 36. An activity installation connecting rod 37 extends outward inside the sleeve 36. The other end of the connecting rod 37 is fixedly connected to a welding torch 30. In order to better control the welding torch 30, a welding control switch 39 and a motor control switch 38 are provided on the handle of the welding torch 30. The welding control switch 39 and the motor control switch 38 are electrically connected to an external power supply. The motor control switch 38 is electrically connected to the first motor 4. The motor control switch 38 includes a motor forward rotation switch and a motor reverse rotation switch, and both the motor forward rotation switch and the motor reverse rotation switch are point switches. The point switch is convenient for controlling the rotation of the first motor 4 and is convenient for welding operations. The driving motor can be controlled by the motor control switch 38, and the start or shutdown of the welding torch can be controlled by the welding control switch 39. A hanging rod 34 in an inverted U shape is provided upward at the top of the slider 32. The hanging rod 34 is hung on the guide rod 31, which is convenient for achieving the effect of limiting sliding;

[0023] A support table 5 is provided at the center of the first side bracket 1 and the second side bracket 2. The support table 5 is in a semi-arc shape with an upward open mouth. The bottom of the support table 5 is supported by a support frame 51. A plurality of balls 52 are evenly provided at the top of the support table 5, which is convenient for supporting the workpiece 8 to be welded;

[0024] On both sides of the support table 5 symmetrically, extension barrels 7 are provided. Specifically, see Figure 1 , the two extension barrels 7 are respectively provided on the first side bracket 1 and the second side bracket 2. A rotating shaft 71 is provided on the outer side of the extension barrel 7. A first pulley 72 is sleeved on the rotating shaft 71. The first pulley 72 and the second pulley 74 are connected by a belt 73. The second pulley 74 is installed at the output shaft end of the second motor 75. In order to better cooperate with the use of the extension barrel 7, two second motors 75 are also provided, which are respectively correspondingly provided on the outer sides of the first side bracket 1 and the second side bracket 2;

[0025] The extension barrel 7 is detachably fitted with a limiting ring 6 on the side facing the support platform 5. In order to effectively cooperate with the limiting ring 6 and the extension barrel 7, the side of the extension barrel 7 facing the limiting ring 6 is provided with a step. The edge of the step is provided with a through hole. The position of the through hole is consistent with the position of the mounting hole 61 of the limiting ring 6. During assembly, the external bolt passes through the through hole and the mounting hole 61 to lock the extension barrel 7 and the limiting ring 6 into one piece. The end of the extension barrel 7 facing the limiting ring 6 is hollow. The limiting ring 6 is a circular hollow structure. Threaded sleeves 62 are fixedly installed circumferentially on the limiting ring 6. At least three threaded sleeves 62 are provided. During assembly, a screw 63 is screwed into the threaded sleeve 62. The workpiece 8 to be welded is fixed in the middle by screwing in the screw 63. In order to avoid the screw 63 affecting the surface of the workpiece 8 to be welded and to increase the friction during contact, a rubber anti-slip pad is provided on the contact end of the screw 63 on the inward side.

[0026] In use, the two arc-shaped massage chair workpieces 8 to be welded are first placed on the central support 5 at one end, and the other end of the workpieces is inserted into the limiting rings 6 on both sides. It should be noted that the limiting rings 6 are already assembled onto the extension barrel 7 at this time, that is, they are locked and fixed by external bolts passing through the through hole on the step of the extension barrel 7 and the mounting hole 61 of the limiting ring 6. The other end of the workpiece is limited by the screw 63 on the limiting ring 6. Specifically, the screw 63 is screwed into the circumferential threaded sleeve 62 of the limiting ring 6, so that the anti-slip pad at the end of the screw 63 presses against the workpiece 8, and firmly clamps it in the middle of the limiting ring 6. After the assembly is completed, the two workpieces to be welded are limited by the limiting rings at both ends, and the part to be welded is limited to the support.

[0027] Start the second motor 75. The switch of the second motor 75 is externally connected and not shown in the figure. It drives the rotating shaft 71 to rotate through the second pulley 74, belt 73 and first pulley 72, thereby driving the entire extension barrel 7 and the clamped workpiece 8 to rotate smoothly on the support table 5. This can also drive the workpiece 8 to be welded to rotate at the same time.

[0028] At this time, the rotation of the first motor 4 is controlled by the motor control switch 38. The first motor 4 drives the ball screw 41 to rotate, which in turn drives the slider 32 and the upper and lower connected structural components to move. The rotation of the slider 32 driven by the first motor 4 facilitates the welding operation. The welding control switch 39 can control the start or stop of the welding torch 30 to weld the workpiece. During the welding process, the sliding of the slider 32 on the ball screw 41 and the rotation of the rotating ball in the hemispherical groove can adjust the position of the welding torch horizontally. The rotation of the rotating ball 35 in the hemispherical groove can adjust the position of the welding torch 30 in the vertical direction, which is convenient for the operator to control the welding torch. The operator operates the welding torch 30 to perform welding operations. The first motor 4 is started by the motor control switch 38 on the welding torch 30 handle. The first motor 4 drives the ball screw 41 to rotate, which drives the slider 32 and the lifting rod 34 to move horizontally along the guide rod 31, thereby adjusting the horizontal position of the welding torch 30. The angle and height of the welding torch 30 can be flexibly adjusted by the movement of the rotating ball 35 in the hemispherical groove of the fixed block 33 and the extension and retraction of the connecting rod 37 in the sleeve 36.

[0029] During the rotation of the workpiece 8 to be welded, the operator controls the welding gun 30 to perform welding through the welding control switch 39, realizing semi-automatic welding of the workpiece circumferential seam, and high-quality welding operation can be completed in one clamping.
