[0030] Reference Figures 1 to 3 According to the tunnel shot peening equipment of the embodiment of the utility model, the shot peening device includes a frame 100, a shot peening mechanism 200, a bearing assembly 300 and a feeding mechanism 400. The shot peening mechanism 200 is arranged on the frame 100, and the shot peening mechanism 200 is provided with a shot peening chamber, and the shot peening chamber has a feed port 210 and a discharge port 220. The bearing assembly 300 is arranged on the frame 100, and the bearing assembly 300 is provided with a bearing groove 301 for bearing a spring 600. The bearing assembly 300 is penetrated through the feed port 210 and the discharge port 220. The feeding mechanism 400 is located at the front side of the feed port 210, and the feeding mechanism 400 includes a feeding seat 410, a conveying wheel 42 0 and a driving member 430, a feeding seat 410 is arranged on the frame 100, a driving member 430 is arranged on the feeding seat 410, and the driving member 430 is used to drive the conveying wheel 420 to rotate, and the outer peripheral side of the conveying wheel 420 can abut against the spring coil of the spring 600, so that the spring 600 enters the shot blasting chamber through the feed port 210, so that the feeding seat 410, the driving member 430 and the conveying wheel 420 can be arranged on the outside of the shot blasting chamber to avoid the feeding seat 410, the driving member 430 and the conveying wheel 420 being worn by high-strength shot particles, which can increase the service life of the feeding mechanism 400, thereby reducing the maintenance cost of the tunnel shot blasting equipment.

[0031] Specifically, when the tunnel-type shot peening equipment is working, high-strength shots are continuously ejected from the shot peening chamber, and the spring 600 is placed on the bearing slot 301 by a manipulator. Thereafter, the driving member 430 drives the conveying wheel 420 to rotate to push the spring 600 located on the bearing slot 301 into the shot peening chamber through the feed port 210 to increase the fatigue life of the spring 600. Since the bearing assembly 300 runs through the shot peening chamber, adjacent springs 600 on the bearing slot 301 can abut against each other, and there is no need to arrange the feeding seat 410, the driving member 430 and the conveying wheel 420 in the shot peening chamber to avoid the feeding seat 410, the driving member 430 and the conveying wheel 420 being worn by high-strength shots, which can increase the service life of the feeding mechanism 400 and reduce the maintenance cost of the tunnel-type shot peening equipment.

[0032] It should be noted that shot peening refers to hitting the surface of the spring 600 with high-strength and high-speed pellets, causing the surface of the spring 600 to undergo work hardening, while reducing or eliminating surface defects of the spring 600, thereby effectively increasing the fatigue life of the spring 600, which will not be described in detail here.

[0033] It should be pointed out that a feeding mechanism 400 is also provided at the rear side of the discharge port 220, which can increase the discharge speed of the tunnel-type shot blasting equipment, which will not be described in detail here.

[0035] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of the present invention, the conveying wheel 420 can move in a direction close to the bearing groove 301, so that the conveying wheel 420 can push the spring 600 to abut against the side wall of the bearing groove 301, so that the conveying wheel 420 can stably push the spring 600 into the shot blasting chamber.

[0036] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of the utility model, the frame 100 is provided with a connecting shaft 110, and the feeding seat 410 is rotatably mounted on the connecting shaft 110. Under the action of the gravity of the driving member 430, the output end of the driving member 430 can rotate downward, so that the conveying wheel 420 can push the spring 600 to abut against the side wall of the bearing groove 301, so that the conveying wheel 420 can stably push the spring 600 into the shot blasting chamber.

[0037] Specifically, the gravity of the portion of the driving member 430 located between the output end and the connecting shaft 110 is greater than half of the gravity of the driving member 430. The side of the driving member 430 close to the output end can rotate downward, which can drive the conveying wheel 420 to move in a direction close to the bearing groove 301, so that the conveying wheel 420 can push the spring 600 to abut against the side wall of the bearing groove 301, so that the conveying wheel 420 can stably push the spring 600 into the shot peening chamber.

[0038] It should be noted that a slide and a linear cylinder can also be set on the feeding seat 410. The feeding seat 410 is fixedly connected to the frame 100. The slide can move in the up and down directions. The linear cylinder drives the slide to move in the up and down directions. The driving member 430 is set on the slide, and the conveying wheel 420 can also move in the direction close to the supporting groove 301. It will not be described in detail here.

[0039] It should be pointed out that since the feeding seat 410 is rotatably connected to the frame 100, the minimum distance between the conveying wheel and the bearing groove 301 can be increased or decreased, and can be compatible with springs 600 of different outer diameters to improve the versatility of the tunnel shot peening equipment, which will not be described in detail here.

[0041] Specifically, the lower end of the buffer 500 abuts against the frame 100, and the upper end of the buffer 500 abuts against the feeding seat 410, which can buffer the conveying wheel 420 to prevent the conveying wheel 420 from damaging the surface of the spring coil of the spring 600, thereby improving the yield rate of the spring 600.

[0042] It should be noted that the buffer member 500 is a member capable of axial elastic deformation, such as a linear spring 600 , and is not limited here.

[0046] It should be noted that there are two positioning parts 122, which are spaced apart along the length direction of the support part 121, and two buffers 500 are correspondingly configured, so that the buffers 500 can effectively buffer the force of the conveying wheel 420 on the spring 600. Of course, in some specific embodiments, the buffers 500 can also be configured with one, three or four, etc., which will not be described in detail here.

The first bearing shaft 310 and the second bearing shaft 320 are arranged side by side and spaced apart. The axial surface of the first bearing shaft 310 and the axial surface of the second bearing shaft 320 form a bearing groove 301, which can reduce the contact area between the bearing assembly 300 and the spring 600, so that the spring 600 can be more fully shot peened, which can increase the service life of the spring 600.

[0051] Specifically, the minimum distance between the first bearing shaft 310 and the second bearing shaft 320 is smaller than the maximum diameter of the spring 600, and the axial surface of the first bearing shaft 310 and the axial surface of the second bearing shaft 320 are both circular structures, which can reduce the contact area between the bearing assembly 300 and the spring 600, so that the spring 600 can be more fully shot peened, thereby increasing the service life of the spring 600.

[0052] In some embodiments of the utility model, at least two supporting components 300, feed ports 210 and discharge ports 220 are respectively configured, and the supporting components 300, feed ports 210 and discharge ports 220 correspond one to one, so that the tunnel-type shot peening equipment can perform the shot peening process on multiple springs 600 at the same time, which can improve the processing efficiency of the tunnel-type shot peening equipment.
