[0023] The utility model provides an alloy metal surface laser shock strengthening device through improvement. Figure 1-Figure 4As shown, it includes a frame 1, in which an adjustment mechanism is arranged, a clamping mechanism and a laser processing mechanism are arranged above the frame 1, and the laser processing mechanism includes a column 2, a screw slide 3, a cross plate 1 4, a cross plate 2 5, a laser head 6, a hydraulic rod 7, a spray head 8, a flexible pipe 9 and a water tank 10, a column 2 is fixedly installed on the outer wall of one side of the frame 1, a screw slide 3 is fixedly installed on the outer side wall of the column 2 opposite to the frame 1, a cross plate 1 4 is fixedly installed on the movable end of the screw slide 3, a group of symmetrically arranged hydraulic rods 7 are fixedly installed on the bottom side of the cross plate 1 4, a cross plate 2 5 is fixedly installed on the side of the two hydraulic rods 7 away from the cross plate 1 4, a laser head 6 is rotatably connected to the bottom of the cross plate 2 5, a water tank 10 is installed on the top position of the column 2 by bolts, a flexible pipe 9 is connected to one side of the water tank 10, and the flexible pipe 9 The end away from the water tank 10 is installed on the outer side of the horizontal plate 2 5, and the flexible tube 9 is connected to the spray head 8 on the side adjacent to the laser head 6; when the device is used, the alloy metal to be processed is first fixed on the supporting plate 13 and the distance between it and the laser head 6 is adjusted, and the motor of the screw slide 3 drives its moving end to drive the horizontal plate 1 4 below to move horizontally in the horizontal direction, and the hydraulic rod 7 drives the horizontal plate 2 5 together with the laser head 6 below to adjust to a suitable processing distance with the alloy metal to be processed, and the light beam of the laser head 6 irradiates the surface of the alloy metal, and impact-strengthens the outer surface of the alloy metal to improve the strength and fatigue resistance of the alloy metal; during the strengthening process, the spray head 8 uses the water flow derived from the water tank 10 through the flexible tube 9 to spray and cool the laser head 6 to avoid excessively high temperature during continuous working of the laser head 6, thereby effectively extending the fatigue life of the laser head 6 working at high temperature.

[0024] Specifically, the adjustment mechanism includes a screw 11, a first motor 12, a supporting plate 13 and a connecting block 14. The inner cavity of the frame 1 is equipped with a screw 11 through a bearing, and the outer side of the frame 1 is equipped with a first motor 12. The output end of the first motor 12 is fixedly connected to the end key of the screw 11. The screw 11 is threadedly fitted with a connecting block 14. The connecting block 14 slides with an inner wall of one side of the frame 1, and the supporting plate 13 is fixedly installed on the connecting block 14. The first motor 12 drives the screw 11 to rotate. Since the connecting block 14 slides with the inner wall of the frame 1 to guide, it can drive the supporting plate 13 above the connecting block 14 to move back and forth along the direction of the screw 11, thereby adjusting the distance between the alloy metal to be processed and the laser head 6, and improving the convenience of loading and unloading.

[0025] Specifically, the clamping mechanism includes a vertical plate 19, an electric push rod 20 and a limit plate 21. A vertical plate 19 is fixedly installed on both sides of the upper surface of the supporting plate 13, and an electric push rod 20 is fixedly installed on the opposite side of the two vertical plates 19. The limit plates 21 are fixedly installed on the side of the two electric push rods 20 away from the vertical plate 19. The alloy metal to be processed is placed on the supporting plate 13, and then the two hydraulic rods 7 respectively drive the limit plates 21 to fit the outer wall of the alloy metal to avoid displacement or shaking of the alloy metal during processing, thereby further improving the strengthening effect of alloy metal processing.

[0026] Specifically, flexible pads 15 are fixedly installed on opposite sides of the two limit plates 21. By providing the flexible pads 15, the friction coefficient between the limit plates 21 and the outer surface of the alloy metal can be increased, thereby improving the clamping effect; irregular or special-shaped alloy metals can also be clamped, thereby further improving the flexibility of the device application.

[0027] Specifically, a wastewater recovery chamber 16 is provided in the inner cavity of the frame 1, and lower water tanks 17 connected to the inner cavity of the wastewater recovery chamber 16 are provided on the four side positions of the upper surface of the frame 1.

[0028] Specifically, shock-absorbing pads 18 are fixedly installed at the four corners of the bottom side of the frame 1; the provision of the shock-absorbing pads 18 is helpful to improve the stability of the device operation.

[0029] Working principle: When the device is used, the alloy metal to be processed is placed on the supporting plate 13, and then the two hydraulic rods 7 respectively drive the limit plates 21 to fit the outer wall of the alloy metal to prevent the alloy metal from being displaced or shaken during the processing, further improving the strengthening effect of alloy metal processing.

[0030] Then the first motor 12 drives the screw 11 to rotate. Since the connecting block 14 slides with the inner wall of the frame 1 to guide, the supporting plate 13 above the connecting block 14 can be driven to move back and forth along the direction of the screw 11, thereby adjusting the distance between the alloy metal to be processed and the laser head 6, and improving the convenience of loading and unloading.

[0031] Secondly, the motor of the screw slide 3 drives its moving end to drive the horizontal plate 1 4 below to move horizontally in the horizontal direction, and the hydraulic rod 7 drives the horizontal plate 2 5 together with the laser head 6 below to adjust to a suitable processing distance with the alloy metal to be processed. The light beam of the laser head 6 irradiates the surface of the alloy metal, performs impact strengthening treatment on the outer surface of the alloy metal, and improves the strength and fatigue resistance of the alloy metal; during the strengthening process, the spray head 8 sprays the laser head 6 with water flow derived from the water tank 10 through the flexible pipe 9 to cool it down, so as to avoid the laser head 6 from being overheated during continuous working, thereby effectively extending the fatigue life of the laser head 6 working at high temperature;

[0032] The spray water for cooling the laser head 6 flows through the lower water tank 17 to the waste water recovery chamber 16 below, and the waste water can be recovered and reused, thereby improving the waste water utilization rate.
