[0002] Laser shock strengthening technology is a new type of laser application surface treatment technology. Compared with traditional surface modification technologies, laser shock strengthening technology can introduce a deeper residual stress layer into materials, refine the surface grains of materials or even produce nanocrystals, and at the same time greatly improve the fatigue life of materials.

[0003] For example, a laser shock strengthening equipment disclosed in the authorized CN 219972401 U. By placing one end of the workpiece between two arc-shaped plates, or placing the two arc-shaped plates on the inner wall of the workpiece and simultaneously abutting against the outer end of the rotating plate, then using the first motor to control the rotation of the screw rod to drive the moving block to move, forcing the two arc-shaped plates to move relatively closer or relatively farther away, so as to clamp the workpiece, and it can clamp hollow tubular and solid tubular workpieces, expanding the application range of the device.

[0004] However, during the use process, it is necessary for the staff to carry the workpiece between the two arc-shaped plates. Since the workpiece is usually made of metal, a large amount of manpower and material resources are consumed during the handling process, and the manual handling speed is slow and the efficiency is low. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a laser shock strengthening device that can realize automatic feeding of workpieces and has higher working efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A laser shock strengthening device, including a workpiece, a bottom plate, and a laser head placed above the bottom plate. A feeding device is provided on the side of the bottom plate. The feeding device includes a conveyor belt and a placement box connected to the conveyor belt.

[0008] On the upper end surface of the bottom plate, there are a first support rod and a second support rod. A first chute is opened on the side wall of the first support rod, and a second chute is opened on the side wall of the second support rod. An adjusting member is provided in the first chute and the second chute. The adjusting member in the first chute is connected to a pushing cylinder. The output end of the pushing cylinder is connected to a rotating shaft, and the rotating shaft is connected to a clamping plate. The adjusting member in the second chute is connected to a rotating cylinder, and the end surface of the rotating cylinder is connected to the clamping plate. The workpiece is placed between the two clamping plates.

[0009] One end of the conveyor belt extends into the bottom plate, and the end face of the conveyor belt is connected to the end face of the bottom plate. A placement box is provided with a receiving cavity for accommodating workpieces. A feeding port is opened on the placement box, and the feeding port is connected to the end face of the conveyor belt and is arranged opposite to the bottom plate.

[0010] The present utility model is further configured as follows: One side of the placement box has an inclined surface, and the inclined surface is placed above the conveyor belt for feeding the conveyor belt. A groove is opened on the bottom surface of the receiving cavity, and a hydraulic cylinder is arranged in the groove. A limiting groove is opened on the upper end surface of the bottom plate, and the output end is connected with a flat plate. The workpieces are stacked on the flat plate, and an electric push rod is arranged on the side wall of the receiving cavity.

[0011] The present utility model is further configured as follows: The adjusting member includes a ball screw, a fixed seat and a stepping motor. The stepping motor and the fixed seat are arranged at both ends of the sliding groove, the ball screw is arranged between the stepping motor and the fixed seat, and a sliding seat is sleeved on the outer wall of the ball screw. The pushing cylinder and the rotating cylinder are connected to the corresponding sliding seats.

[0012] The present utility model is further configured as follows: An infrared sensor I is arranged on the support rod, and an infrared sensor II is arranged on the inner wall of the receiving cavity.

[0015] Compared with the deficiencies of the prior art, the beneficial effects of the present utility model are as follows:

[0016] By adding a conveyor belt and a placement box, the operator only needs to place the workpiece on the flat plate in the receiving cavity. When processing is required, the hydraulic cylinder pushes the flat plate to rise. When the flat plate rises to the inclined surface, the electric push rod pushes the workpiece out, so that the workpiece falls onto the conveyor belt. Since the other end of the conveyor belt is connected to the bottom plate, the workpiece will move onto the bottom plate under the influence of inertia and fall into the limiting groove for limiting. One end of the clamping plate is placed in the limiting groove, and then the pushing cylinder pushes to clamp the workpiece. Finally, it is lifted by the ball screw to perform impact strengthening on the workpiece, and the rotating cylinder can drive the workpiece to rotate for all-round strengthening, reducing manpower and increasing work efficiency at the same time.

The adjusting member in the chute two 9 is connected with a rotating cylinder 13, and the end face of the rotating cylinder 13 is connected with a second clamp. The workpiece 1 is placed between the two clamping plates 12. A limiting groove for the workpiece 1 to be placed is provided on the upper end face of the bottom plate 2. One end of the clamping plate 12 extends into the limiting groove. The pushing cylinder 10 pushes out the clamping plate 12, so that both ends of the workpiece 1 are in contact with the clamping plate 12, and the workpiece 1 is fixed. The rotating cylinder 13 drives the workpiece 1 to rotate, so that the workpiece 1 is comprehensively strengthened.

[0027] The adjusting member includes a ball screw 20, a fixed seat 21 and a stepping motor 22. The stepping motor 22 and the fixed seat 21 are placed at both ends of the chute.

[0030] Working principle: When in use, the operator places the workpiece 1 into the accommodating cavity 14, and then turns on the laser head 3 and the loading device through the controller 26. When processing is required, the hydraulic cylinder 17 pushes the flat plate 18 to rise. When the flat plate 18 rises to the inclined surface 16, the electric push rod 19 pushes out the workpiece 1, causing the workpiece 1 to fall onto the conveyor belt 4. Since the other end of the conveyor belt 4 is connected to the bottom plate 2, the workpiece 1 will move onto the bottom plate 2 under the influence of inertia and fall into the limiting groove for positioning. One end of the clamping plate 12 is placed in the limiting groove, and then the pushing cylinder 10 is pushed to clamp the workpiece 1. Finally, it is lifted by the ball screw 20 to perform impact strengthening on the workpiece 1. The rotating cylinder 13 can drive the workpiece 1 to rotate for all-round strengthening. After processing is completed, the pushing cylinder 10 resets, and the operator removes the processed workpiece 1.
