[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A three-dimensional view of the main structure of the fixture for the mold-saving processing of vehicle lights provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the enlarged structure of shown; Figure 3 This is a plan view of the main structure of the clamping fixture for the mold-saving processing of vehicle lights provided by the utility model.

[0021] In the specific implementation process, Figure 1-Figure 3 As shown, it includes a fixed tray 1, two support seats 2 are fixed above the fixed tray 1 at intervals, a first support shaft 3 is movably arranged between the two support seats 2 through bearings, a load-bearing seat 4 is fixed on the first support shaft 3, and a servo motor 10 is installed above the fixed tray 1. The specific model of the servo motor is 10130-15025, which has the advantages of high precision, large torque and fast response. A first gear 11 is installed at the output end of the servo motor 10, one end of the first support shaft 3 extends out of the support seat 2 and is installed with a second gear 12, and the first gear 11 is meshed with the second gear 12.

[0022] A second supporting shaft 5 is fixed on the load-bearing seat 4, a trapezoidal supporting frame 6 is fixed above the load-bearing seat 4, the second supporting shaft 5 passes through the trapezoidal supporting frame 6, and the second supporting shaft 5 is movably connected to the trapezoidal supporting frame 6 through a bearing, a plurality of first clamping blocks 13 are fixed at circumferential intervals on the top of the second supporting shaft 5, a first limiting seat 14 is fixed on one side of the trapezoidal supporting frame 6, a sliding column 15 is penetrated by the first limiting seat 14, a second clamping block 16 is fixed at one end of the sliding column 15, a support plate 17 is installed at the other end of the sliding column 15, a limiting spring 18 is sleeved on the sliding column 15, one end of the limiting spring 18 is fixed on the first limiting seat 14, and the other end of the limiting spring 18 is fixed to the surface of the support plate 17.

[0023] A third support shaft 7 is movably arranged between the trapezoidal support frames 6 through bearings, a support pallet 8 is arranged above the trapezoidal support frame 6, the bottom of the support pallet 8 is fixedly connected to the third support shaft 7, a workpiece magnetic tray 9 is fixed above the support pallet 8, one end of the third support shaft 7 passes through the trapezoidal support frame 6 and is provided with a worm gear 19, two second limit seats 20 are fixed at intervals on one side of the trapezoidal support frame 6, a worm 21 is movably arranged between the two second limit seats 20, the worm 21 is meshed with the worm wheel 19, and a crank 22 is installed on the worm 21 to facilitate the staff to rotate the worm 21.

[0024] Working principle of the utility model: When the device is used, the workpiece can be fixed on the workpiece magnetic tray 9. When the height of the workpiece needs to be adjusted, it is only necessary to start the supporting cylinder at the bottom of the fixed tray 1. By starting the servo motor 10, under the transmission action of the first gear 11 and the second gear 12, the first supporting shaft 3 rotates and drives the workpiece to rotate;

[0025] The staff can adjust the horizontal orientation of the workpiece according to actual needs. They only need to pull the support plate 17 to drive the second clamping block 16 to disengage from between the two first clamping blocks 13. At this time, the orientation of the trapezoidal support frame 6 can be rotated. After the adjustment is completed, the support plate 17 is released. Under the action of the limit spring 18, the second clamping block 16 is reset, so that the position of the trapezoidal support frame 6 is fixed;

[0026] When the workpiece needs to be rotated left or right, the staff only needs to turn the crank 22 to drive the worm 21 to rotate. Under the transmission action of the worm 21 and the worm wheel 19, the support plate 8 rotates along with the third support shaft 7. After the crank 22 is released, the support plate 8 stops at this position because the worm wheel 19 and the worm 21 are meshed and have a self-locking effect.

[0027] In summary, this clamping fixture can rotate forward and backward, left and right, and horizontally. When processing mold-saving workpieces, the product surface is consistent with the processing direction of the operator, and the operator can use appropriate processing techniques, thereby reducing the operator's repeated clamping and improving processing efficiency.
