[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 3According to the tunnel shot peening equipment of the embodiment of the utility model, it 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 500. 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. The feeding mechanism 400 includes a feeding frame 410, a slide seat 420 and a pushing assembly 430, the feeding rack 410 is arranged on the frame 100, the slide 420 is movably arranged on the feeding rack 410 and is connected with the driving assembly 440, the pushing assembly 430 is arranged on the slide 420, and the pushing assembly 430 is used to abut against the spring coil of the spring 500 to push the spring 500 into the shot blasting chamber through the feed port 210. In this way, the driving assembly 440, the slide 420 and the pushing assembly 430 can be arranged on the outside of the shot blasting chamber to avoid the driving assembly 440, the slide 420 and the pushing assembly 430 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.

[0032] Specifically, when the tunnel-type shot peening equipment is working, high-strength shots are continuously ejected from the shot peening chamber, and the spring 500 is placed on the bearing slot 301 by a manipulator. Then, the driving component 440 drives the slide 420 to move in a direction close to the feed port 210, so that the pushing component 430 pushes the spring 500 located on the bearing slot 301 into the shot peening chamber through the feed port 210 to increase the fatigue life of the spring 500. Then, the driving component 440 drives the slide 420 to move in a direction away from the feed port 210 to push the next spring 500 into the shot peening chamber. Since the bearing component 300 runs through the shot peening chamber, adjacent springs 500 on the bearing slot 301 can abut against each other, and there is no need to set them in the shot peening chamber to avoid the drive component 440, the slide 420 and the pushing component 430 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.

[0033] It should be noted that shot peening refers to hitting the surface of the spring 500 with high-strength and high-speed pellets, causing the surface of the spring 500 to undergo work hardening, while reducing or eliminating surface defects of the spring 500, thereby effectively increasing the fatigue life of the spring 500, which will not be described in detail here.

[0034] 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] It should be pointed out that the shot blasting chamber has a shot inlet and a shot outlet, and the shot blasting mechanism 200 includes a supply component 230 and a recovery component. The supply component 230 is connected to the shot inlet to provide shot particles, and the recovery component is connected to the shot outlet to recover the shot particles, which will not be described in detail here.

[0036] Reference Figures 4 to 6 In some embodiments of the utility model, the pushing assembly 430 includes a pushing seat 431 and a pushing piece 432. The pushing seat 431 is rotatably connected to the slide 420. One end of the pushing piece 432 is connected to the pushing seat 431. When the driving assembly 440 drives the slide 420 to move, the other end of the pushing piece 432 can enter or exit between adjacent spring coils of the spring 500, which can facilitate pushing the spring 500 into the shot peening chamber.

[0037] Specifically, when the driving component 440 drives the slide 420 to move in a direction close to the feed port 210, the end of the pushing piece 432 away from the pushing seat 431 enters between adjacent spring coils of the spring 500, so that the end of the pushing piece 432 away from the pushing seat 431 can abut against the side of the spring coil facing the feed port 210 to push the spring 500 to move in a direction close to the feed port 210. When the driving component 440 drives the slide 420 to move in a direction away from the feed port 210, the end of the pushing piece 432 away from the pushing seat 431 exits from between adjacent spring coils of the spring 500 to move to the next spring 500. Thereafter, the driving component 440 drives the slide 420 to move in a direction close to the feed port 210. In this way, the spring 500 can be continuously pushed to move in a direction close to the feed port 210, so that the spring 500 can continue to enter the shot peening chamber.

[0038] It can be understood that the pushing seat 431 can also be slidably arranged on the sliding seat 420 along the up and down directions. The pushing seat 431 is connected to a cylinder, and the cylinder can slide along the up and down directions through the pushing seat 431, or one end of the pushing member 432 can enter or exit between adjacent spring coils of the spring 500, which is not described in detail here.

[0039] Reference Figures 4 to 6 In some embodiments of the utility model, a limiting structure is provided between the pushing seat 431 and the slide seat 420, and the limiting structure is used to limit the pushing seat 431 from rotating in a direction away from the feed port 210, so that the pushing member 432 can stably push the spring 500 to move in a direction close to the feed port 210.

[0040] It should be noted that the limiting structure can also be disposed between the slide seat 420 and the pusher 432 , which will not be described in detail herein.

[0041] Reference Figures 4 to 6In some embodiments of the utility model, the limiting structure includes a limiting member 450 arranged on the slide seat 420, one end of the limiting member 450 can abut against the pushing seat 431, and can limit the pushing seat 431 from rotating in a direction away from the feed port 210, so that the pushing member 432 can stably push the spring 500 to move in a direction close to the feed port 210.

[0042] Specifically, when the driving component 440 drives the slide 420 to move in a direction close to the feed port 210, one end of the limit member 450 can abut against the push seat 431. When the driving component 440 drives the slide 420 to move in a direction away from the feed port 210, one end of the limit member 450 can separate from the push seat 431, and can limit the push seat 431 from rotating in a direction away from the feed port 210, so that the push member 432 can stably push the spring 500 to move in a direction close to the feed port 210.

[0043] It should be noted that the limiting structure can also be a structure in which a waist-shaped hole and a limiting pin are coordinated. The waist-shaped hole is arranged on the slide 420. The waist-shaped hole is an arc-shaped structure and is concentrically arranged with the rotating connection position of the slide 420. The limiting pin is arranged on the pusher seat 431. The limiting pin passes through the waist-shaped hole and can abut against the side wall of the waist-shaped hole. It can also limit the pusher seat 431 from rotating in the direction away from the feed port 210. It will not be described in detail here.

[0044] Reference Figures 4 to 6 In some embodiments of the utility model, the slide 420 includes a first connecting member 421 and a second connecting member 422 connected to the first connecting member 421, the first connecting member 421 is connected to the output end of the driving assembly 440, the second connecting member 422 is rotatably connected to the pushing seat 431, the limit member 450 is connected to the first connecting member 421, and the limit member 450 is located below the second connecting member 422, which can facilitate the assembly of the feeding mechanism 400.

[0045] Specifically, the first connecting member 421 and the second connecting member 422 are overall L-shaped structures, and the end of the first connecting member 421 away from the second connecting member 422 is connected to the output end of the driving component 440, and the end of the second connecting member 422 away from the first connecting member 421 is rotatably connected to the pushing seat 431 through a connecting shaft. There are two limit members 450, and the two limit members 450 are arranged side by side and spaced apart, and the two limit members 450 are located on opposite sides of the output end of the driving component 440. The end of the limit member 450 away from the first connecting member 421 can abut against the pushing seat 431, which can facilitate the assembly of the feeding mechanism 400.

[0046] It should be pointed out that the limiting member 450 may be configured with one, three, or four, etc., which is not limited here.

[0047] In some embodiments of the present invention, the first connecting member 421 is connected to the second connecting member 422 by bolting or clamping, which can facilitate the assembly of the slide seat 420.

[0048] It should be pointed out that the first connecting member 421 and the second connecting member 422 may also be an integrated structure, which can reduce the number of molds to reduce the production cost of the molds, thereby reducing the production cost of the tunnel-type shot peening equipment.

[0049] Of course, in some specific implementations, the first connection member 421 may also be connected to the second connection member 422 by welding, wherein the welding method includes but is not limited to resistance welding, laser welding or ultrasonic welding.

[0050] In some embodiments of the present invention, the pushing seat 431 and the pushing member 432 are located above the bearing assembly 300 , so that the pushing member 432 can automatically enter between adjacent coils of the spring 500 under the action of its own gravity.

[0051] Reference Figure 1 In some embodiments of the utility model, the bearing assembly 300 includes a first bearing shaft 310 and a second bearing shaft 320. 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 500, so that the spring 500 can be more fully shot peened, which can increase the service life of the spring 500.

[0052] 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 500, 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 500, so that the spring 500 can be more fully shot peened, thereby increasing the service life of the spring 500.

[0053] In some embodiments of the present invention, 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 500 at the same time, which can improve the processing efficiency of the tunnel-type shot peening equipment.

[0054] In some embodiments of the present invention, the driving assembly 440 is a linear cylinder, which can reduce the production cost of the tunnel-type shot peening equipment.

[0055] Of course, in some specific implementations, the driving assembly 440 can also be a structure in which a motor and a lead screw cooperate, and can drive the slide 420 to move, which is not limited here.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
