[0002] Cylinder head casting is an important component of engine, and its manufacturing process and material selection have a direct impact on the performance of the engine, and the commonly used materials of cylinder head casting include gray cast iron, alloy cast iron or aluminum alloy. Gray cast iron is widely used due to its good casting performance and cost-effectiveness, and the cylinder head casting usually needs to use a shot blasting machine to project shot particles to the surface of the casting during the machining process to remove dirt, oxides, coatings and the like.

[0003] At present, the existing shot blasting machine is fixed in position inside the shot blasting mechanism, in order to more comprehensively process the surface of the cylinder head casting, the casting is usually fixed by a clamping mechanism, and then the casting is rotated by the rotation of the clamping mechanism to make the casting fully contact with the shot particles, but since the clamping mechanism contacts the casting, the contact area cannot be treated by shot blasting, and the casting needs to be re-treated by shot blasting later, which not only is troublesome to operate but also wastes time, resulting in low efficiency of casting treatment.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 In this embodiment of the utility model, the shot blasting equipment for cylinder head casting includes a housing 1, a shot blasting mechanism 2, a conveying mechanism 3, a moving mechanism 4, and a clamping mechanism 5. The housing 1 is installed on the ground, and one side of the housing 1 is an open structure. A door panel is hinged to the edge of the open side of the housing 1. The shot blasting mechanism 2 is located at the inner top of the housing 1. The conveying mechanism 3 is located on one side of the housing 1. The feed port of the conveying mechanism 3 is connected to the inner bottom of the housing 1, and the discharge port of the conveying mechanism 3 is connected to the inside of the shot blasting mechanism 2 through a connecting pipe. The moving mechanism 4 is located at the inner top of the housing 1 and can control the movement of the shot blasting mechanism 2. The clamping mechanism 5 is rotatably connected between the two opposite sides of the housing 1 and located below the shot blasting mechanism 2. It can clamp and fix the casting. The clamping mechanism 5 includes two vertically symmetrical C-shaped plates 51 that move inside the housing 1. Grooves 511 are provided at both ends of the opposite sides of the two C-shaped plates 51. A rotating shaft is rotatably connected inside the grooves 511, and a round roller 512 is fixedly connected to the outer wall of the rotating shaft.

[0033] Specifically, the casting is first placed between two U-shaped plates 51, which clamp and fix the casting in place. Then, driven by the conveying mechanism 3 and the shot blasting mechanism 2, shot blasting particles are sprayed onto the casting. Simultaneously, the moving mechanism 4 drives the shot blasting mechanism 2 to move, and the rotation of the two U-shaped plates 51 causes the casting to rotate inside the housing 1, allowing the shot blasting particles to be sprayed onto the surface of the casting more comprehensively (to prevent the casting from being thrown out and to ensure that the casting is processed more thoroughly, the rotation speed of the U-shaped plates 51 is relatively slow). The area in contact with the roller 512 cannot be treated by shot blasting particles. Therefore, by rotating the two rollers 512 at the same mold plate 51 in the same direction and the upper and lower rollers 512 in opposite directions, the four rollers 512 can move the casting. When the area on the surface of the casting that was originally in contact with the roller 512 is exposed, the shot blasting particles sprayed by the shot blasting mechanism 2 can treat the area that was originally blocked, so that the casting can be treated more comprehensively. There is no need to treat the blocked area separately later, thereby improving the processing efficiency of the cylinder head.

[0034] Example 1

[0035] like Figure 5As shown, in this embodiment, one end of the rotating shaft passes through the side of the C-shaped plate 51 at the corresponding position and is fixedly connected to a worm gear 513. Both ends of one side of the C-shaped plate 51 are fixedly connected to support blocks 514. The opposite sides of the two support blocks 514 at opposite positions are rotatably connected to worms 515 that mesh with the worm gear 513 at the corresponding position. A connecting rod 516 is fixedly connected between the two worms 515 at opposite positions. A gear 517 is fixedly connected to the outer wall of the connecting rod 516. A motor housing 518 is fixedly connected to one side of the C-shaped plate 51. A second drive motor is installed inside the motor housing 518. The output end of the second drive motor passes through the motor housing 518 at the corresponding position and is fixedly connected to a second gear 519 that meshes with the gear 517.

[0036] In this embodiment, the second motor drives the second gear 519 to drive the first gear 517 at the corresponding position to rotate the connecting rod 516 at the corresponding position. The rotating connecting rod 516 can rotate the two worm gears 515 at the corresponding position, thereby rotating the two worm wheels 513 at the corresponding position, and thus rotating the two rollers 512 at the corresponding position. Since the two rollers 512 at the same molded plate 51 rotate in the same direction, the two worm gears 515 at the same connecting rod 516 rotate in opposite directions.

[0037] like Figure 4 As shown, in this embodiment, through holes 11 are provided on both opposite sides of the housing 1. A turntable 55 rotates through the inside of the through holes 11. A rectangular frame 52 is fixedly connected to one side of each of the two turntables 55. A fixing plate 53 is slidably connected to both ends of the rectangular frame 52 and fixedly connected to the corresponding C-shaped plate 51. An electric push rod 54 is fixedly connected to both ends of the rectangular frame 52 and fixedly connected to the corresponding fixing plate 53. A fixing block 12 is fixedly connected to the top of one side of the housing 1. A connecting shaft is fixedly connected to one side of the turntable 55 near the fixing block 12. A worm gear 56 is fixedly connected to the outer wall of the connecting shaft. A drive motor 57 is fixedly connected to the bottom of one side of the housing 1. A worm gear 58 that meshes with the worm gear 56 is fixedly connected to the output end of the drive motor 57.

[0038] In this embodiment, the casting is clamped and fixed by two C-shaped plates 51 by the driving of four electric push rods 54. Then, the worm gear 58 drives the worm wheel 56 to rotate by the driving of the third drive motor 57. The rotating worm wheel 56 can rotate the turntable 55 at the corresponding position. The rotating turntable 55 can drive the two C-shaped plates 51 to rotate through the fixing plate 53, so that the casting can rotate inside the housing 1, thereby improving the processing efficiency of the cylinder head.

[0039] Example 2

[0040] like Figure 3 As shown, in this embodiment, the moving mechanism 4 includes a moving plate 41, two symmetrical connecting blocks 42, a lead screw 43, and a drive motor 44. The moving plate 41 is located inside the housing 1 and moves back and forth. The moving plate 41 is fixedly connected to the top surface of the shot blasting mechanism 2. The two symmetrical connecting blocks 42 are fixedly connected to the two ends of the top surface of the moving plate 41. The lead screw 43 is rotatably connected between two opposite sides inside the housing 1 and is screwed through and engaged with the connecting block 42 at the corresponding position. The drive motor 44 is fixedly connected to one side of the housing 1. The output end of the drive motor 44 passes through the side of the housing 1 and is fixedly connected to the lead screw 43. A limiting rod 45 that slides through another connecting block 42 is fixedly connected between two opposite sides inside the housing 1.

[0041] In this embodiment, the drive motor 44 drives the lead screw 43 to move the moving plate 41 inside the housing 1. The moving plate 41 can drive the shot blasting mechanism 2 to move. By rotating the drive motor 44 in both directions, the shot blasting mechanism 2 moves back and forth inside the housing 1, thereby making the cylinder head treatment more comprehensive.
