DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 , Figure 2 As shown, a rotary workbench for welding a motorcycle frame comprises a base plate 1, a first motor 2 is fixedly connected to the axis center of the upper surface of the base plate 1, a rotating frame 3 is fixedly connected to the output end of the first motor 2, four annular fixed platforms 4 are fixedly connected to the outer wall of the rotating frame 3, two symmetrically distributed fixing mechanisms 5 are fixedly connected to the upper sides of the four fixed platforms 4 through columns, a cleaning mechanism 6 is fixedly connected to the upper sides of the four fixed platforms 4, a support frame 7 is fixedly connected to the upper surface of the base plate 1 near the middle, and the lower side of the rotating frame 3 is overlapped on the upper side of the support frame 7.

[0026] It should be noted that the support frame 7 is used to support the rotating frame 3 to prevent the rotating frame 3 from bearing too much weight and causing its own deformation. The first motor 2 drives the rotating frame 3 to rotate, and when the rotating frame 3 rotates, it drives the four fixed platforms 4 to revolve.

[0027] like Figure 1 , Figure 3As shown, the fixing mechanism 5 includes a mechanism frame 51, the lower side of the mechanism frame 51 is fixedly connected to the upper surface of the fixing platform 4 near the edge through a column, one end of the mechanism frame 51 is fixedly connected to a second motor 52, the output end of the second motor 52 is fixedly connected to a screw rod 53, and two screw rods 53 are symmetrically distributed on the inner side of the mechanism frame 51, the outer wall of the screw rod 53 is threadedly connected to two symmetrically distributed moving seats 54, and the upper surfaces of the two moving seats 54 are fixedly connected to symmetrically distributed clamping blocks 55.

[0028] It should be noted that the second motor 52 drives the screw rod 53 to rotate. When the screw rod 53 rotates, the moving seat 54 moves along the screw rod 53. The screw rod 53 is a bidirectional screw rod, which contains two threads in opposite directions. The two moving seats 54 are threadedly connected to the threads in different directions, so that the two moving seats 54 move in opposite directions along the screw rod 53. When the moving seat 54 moves, it drives the clamping block 55 to move, so that the clamping block 55 clamps the motorcycle frame.

[0029] like Figure 3 As shown, the ends of the outer walls of the two screw rods 53 away from the second motor 52 are fixedly connected to sprocket wheels 56 , and the side surfaces of the sprocket wheels 56 are meshingly connected to chains 57 .

[0030] It should be noted that when the screw rod 53 on the second motor 52 rotates, the sprocket 56 thereon is driven to rotate, and by means of the chain 57, the two chains 57 are caused to rotate synchronously in the same direction, so that the forces on both sides of the moving seat 54 are balanced.

[0031] like Figure 3 As shown, a rubber pad 59 is fixedly connected to the sides of the two clamping blocks 55 that are close to each other.

[0032] It should be noted that the rubber pad 59 is used to enhance the friction between the clamp block 55 and the motorcycle frame, and to prevent the clamp block 55 from squeezing and deforming the motorcycle frame due to excessive movement of the clamp block 55 .

[0033] like Figure 4 As shown, the cleaning mechanism 6 includes a blowing fan 62 and a collecting box 63. The lower side of the blowing fan 62 is fixedly connected to the upper side of the fixed table 4 near the first motor 2, and the lower side of the collecting box 63 is fixedly connected to the upper side of the fixed table 4 away from the first motor 2, and the blowing fan 62 and the collecting box 63 are both semi-circular in shape.

[0034] It should be noted that the blowing fan 62 blows a breeze toward the collecting box 63 , so that the welding slag is blown into the inner side of the collecting box 63 , so that the upper side of the rotating frame 3 is kept clean.

[0035] like Figure 4 , Figure 5As shown, the bottom of the collecting box 63 is movably sleeved with a collecting cylinder 67, the outer wall of the collecting cylinder 67 is movably sleeved with a fixing seat 66 near the bottom, the outer side of the fixing seat 66 is movably sleeved with a mechanism cylinder 64 near the bottom, the outer wall of the mechanism cylinder 64 is slidably connected to the annular groove opened on the upper side of the base plate 1 near the bottom, the inner side of the mechanism cylinder 64 is movably sleeved with a spring 65, and the spring 65 is located on the inner side of the fixing seat 66.

[0036] It should be noted that the welding slag in the collection box 63 falls to the inner side of the collection tube 67, and the welding slag is collected. The spring 65 pushes the fixing seat 66 upward, causing the fixing seat 66 to push the collection tube 67 upward, causing the outer wall of the collection tube 67 to be movably sleeved on the lower side of the collection box 63 near the upper side. When removing the collection tube 67, you only need to push the collection tube 67 downward, causing the collection tube 67 to detach from the lower side of the collection box 63, so that the collection tube 67 is removed.

[0037] like Figure 5 As shown, the lower side of the mechanism cylinder 64 is rotatably connected to a plurality of evenly distributed balls 68 .

[0038] It should be noted that the ball bearings 68 are used to reduce the friction between the base plate 1 and the mechanism tube 64 , thereby extending the service life of the mechanism tube 64 and the ball bearings 68 .

[0039] like Figure 4 As shown, a protective pad 61 is fixedly connected to the upper surface of the fixing platform 4 .

[0040] It should be noted that the protective pad 61 is made of high temperature resistant material to prevent welding slag from falling directly onto the fixing platform 4 , thereby reducing the service life of the fixing platform 4 .

[0041] The working principle of the utility model is as follows: first, the protective pad 61 is made of high temperature resistant material to prevent welding slag from falling directly on the fixed platform 4, which reduces the service life of the fixed platform 4. The blowing fan 62 blows a breeze to the collection box 63, so that the welding slag is blown into the inner side of the collection box 63, and the welding slag in the collection box 63 falls to the inner side of the collection tube 67 to collect the welding slag. The spring 65 pushes the fixed seat 66 upward, so that the fixed seat 66 pushes the collection tube 67 upward, so that the outer wall of the collection tube 67 is close to the upper side and is movably sleeved on the collection tube. When removing the collecting tube 67, it is only necessary to push down the collecting tube 67, so that the collecting tube 67 is separated from the lower side of the collecting box 63, so that the collecting tube 67 is removed, and the breeze is blown out by the blowing fan 62 to blow the welding slag on the fixed platform 4 into the inner side of the collecting box 63, so that the upper side of the fixed platform 4 is kept clean to avoid affecting the welding efficiency. At the same time, the blown welding slag falls into the inner side of the collecting tube 67, and the welding slag is collected to avoid the welding slag falling everywhere and affecting the subsequent sorting. Finally, the second motor 52 drives the screw rod 53 to rotate, and the screw rod 5 When the moving seat 54 rotates, it moves along the screw rod 53. The screw rod 53 is a bidirectional screw rod, which has two threads in opposite directions. The two moving seats 54 are respectively threadedly connected with threads in different directions, so that the two moving seats 54 move in opposite directions along the screw rod 53. When the moving seat 54 moves, it drives the clamping block 55 to move, so that the clamping block 55 clamps the motorcycle frame. When the screw rod 53 on the second motor 52 rotates, it drives the sprocket 56 thereon to rotate. Relying on the chain 57, the two chains 57 rotate synchronously in the same direction, so that the moving seat 54 moves in the opposite direction along the screw rod 53. The forces on both sides of the seat 54 are balanced, and the rubber pad 59 is used to enhance the friction between the clamp block 55 and the motorcycle frame, while preventing the clamp block 55 from squeezing and deforming the motorcycle frame due to excessive movement of the clamp block 55. The second motor 52 drives the screw rod 53 to rotate, causing the two clamp blocks 55 to move in the opposite direction along the screw rod 53, so that the clamp blocks 55 clamp the motorcycle frame. The two fixing mechanisms 5 respectively fix two positions of the motorcycle frame, so that the motorcycle frame is fixed on the fixing platform 4, so as to avoid shaking of the motorcycle frame during welding or rotation, which affects welding.
