[0002] The crankcase is an important component in internal combustion engines (such as engines used in cars, motorcycles, ships, etc.). It is a box structure that houses the crankshaft. The crankshaft is a key component that converts the reciprocating linear motion of the piston in the cylinder into rotational motion, and the crankcase provides a space for the crankshaft to be installed and operated, and is usually divided into two parts: the upper crankcase (also called the cylinder head) and the lower crankcase.

[0003] At present, in the crankcase processing process, an automated horizontal conveyor belt is usually used to transport the workpiece to the entrance of the processing equipment. When there is a large height difference between the output end of the conveyor belt and the entrance of the processing equipment, especially when facing a heavy crankcase, the traditional manual assisted loading method is not only time-consuming and labor-intensive, but may also cause damage to the workpiece or personal injury due to improper operation, seriously affecting production efficiency and safety.

[0010] Preferably, the outer walls at the bottom ends of both sides of the auxiliary frame and the outer walls at both sides of the end of the horizontal conveyor belt are provided with threaded barrels, and locking screws are interspersed and connected between the threaded barrels in the same group.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides a technical solution: a feeding device for crankcase processing, comprising a horizontal conveyor belt 1, the horizontal conveyor belt 1 is used as a basic transmission platform for continuously transporting workpieces, and an auxiliary frame 2 is detachably installed at the end of the horizontal conveyor belt 1, the auxiliary frame 2 is a rectangular frame structure, a horizontally distributed carrying plate 3 is provided on the auxiliary frame 2, and a support plate 4 is welded and fixed at the bottom end of the auxiliary frame 2, a plunger hydraulic cylinder 5 for driving the carrying plate 3 to rise and fall vertically is provided on the top of the support plate 4, the bottom end of the plunger hydraulic cylinder 5 is fixed to the middle of the top of the support plate 4 by bolts, and the output end of the top of the plunger hydraulic cylinder 5 is welded and fixed to the middle of the bottom of the carrying plate 3 by a connecting piece, and vertically distributed protective plates 6 are provided on both sides of the top of the carrying plate 3, and the protective plates 6 An elastic pressure block 9 is provided on each corresponding side. The elastic pressure block 9 can be made of rubber material, and a cylinder 12 for pushing the protective plate 6 to move laterally is fixedly installed at the bottom of the supporting plate 3 by bolts. The horizontal conveyor belt 1 of this structure is used for subsequent vertical lifting when the crankcase is loaded by installing an auxiliary frame 2 at the end. When the plunger hydraulic cylinder 5 is driven, it will drive the supporting plate 3 to move vertically, so that the heavy crankcase can be lifted smoothly during the transfer process, reducing vibration and potential damage during the transportation process, improving safety, and the cylinder 12 can push the protective plate 6 to move laterally, so as to adjust the position of the elastic pressure block 9 during the crankcase loading process, so as to achieve better guidance and protection of the crankcase, and ensure the smoothness of the loading process. The protective plate 6 is symmetrically fixed with positioning shafts 10 at the upper and lower ends, and the upper and lower ends of the back side of the elastic pressure block 9 are fixed with connecting ports 13, and the outer end of the connecting port 13 is provided with a pressure column 14 that can be movably extended into the inner part of the outer end of the positioning shaft 10, and the outer sleeve of the connection between the pressure column 14 and the connecting port 13 is provided with a compression spring 15. The integration of the elastic pressure block 9 and the connecting port 13, the pressure column 14 and the compression spring 15 of this structure forms a dynamic buffer system, which can absorb impact through the elastic action of the compression spring 15 when the workpiece is placed or removed. In order to protect the workpiece from damage, it also ensures the stable positioning of the workpiece on the carrier plate 3 to prevent slipping. A rectangular recess is provided in the middle of the top of the carrier plate 3, and a plurality of rollers 16 are rotatably connected to the rectangular recess on the top of the carrier plate 3. The inner walls on both sides of the rollers 16 are connected to the inner walls on both sides of the rectangular recess of the carrier plate 3 through a rotating shaft. The rollers 16 of this structure can rotate in the rectangular recess of the carrier plate 3, so that the crankcase can roll smoothly when being lifted or lowered, reducing friction and reducing wear on the crankcase surface, while improving working efficiency. A push rod running through the carrier plate 3 is provided in the middle of the bottom of the protective plate 6, and a through port matching the push rod at the bottom end of the protective plate 6 is symmetrically provided on the carrier plate 3. Two cylinders 12 are provided, and the output ends are both facing outwards.The output end is fixedly connected with the corresponding push rod at the bottom of the protective plate 6. When the cylinder 12 of this structure is driven, it can push the push rod at the bottom of the protective plate 6 to move in the opening on the carrier plate 3 to achieve the effect of driving the two protective plates 6 to move away from or close each other. Guide blocks 11 are welded and fixed on both sides of the carrier plate 3, and the inner walls on both sides of the auxiliary frame 2 are provided with guide grooves that match the guide block 11 structure. The carrier plate 3 of this structure can drive the guide blocks 11 to slide in the guide grooves on the inner walls on both sides of the auxiliary frame 2 during vertical lifting, ensuring that the carrier plate 3 remains stable during the vertical lifting process and prevents deflection. The outer walls of the bottom ends of both sides of the auxiliary frame 2 and the outer walls on both sides of the end of the horizontal conveyor belt 1 are welded and fixed with threaded barrels 7, and the threaded barrels 7 are interspersed and connected with locking screws 8 in the same group. The threaded barrels 7 of this structure cooperate with the locking screws 8 to ensure the firm connection between the auxiliary frame 2 and the horizontal conveyor belt 1, and the stability and safety of the structure can be maintained even when handling heavy-loaded workpieces to prevent accidental loosening.

[0019] Working principle: When using the crankcase processing feeding device, first, the auxiliary frame 2 is firmly installed at the end of the horizontal conveyor belt 1 by using the threaded tube 7 and the locking screw 8. When the horizontal conveyor belt 1 transports the crankcase to the end and places it on the carrier plate 3, the two cylinders 12 are started. When the cylinders 12 are driven, the two protective plates 6 are driven to move laterally until the two protective plates 6 are closed together and drive the elastic pressure blocks 9 to press on both sides of the crankcase. At this time, the elastic pressure blocks 9 will drive the pressure column 14 to generate a certain degree of compression on the outer end of the positioning shaft 10 through the connecting port 13, and the pressure column 14 will also compress the compression spring 15 when it is compressed. A force is generated, so that the crankcase is dynamically and stably limited, and then the plunger hydraulic cylinder 5 is started. When the plunger hydraulic cylinder 5 is driven, it can drive the carrying plate 3 to rise and fall vertically smoothly, and the carrying plate 3 will also drive the guide block 11 to slide in the guide groove on the inner wall on both sides of the auxiliary frame 2 when it is lifted vertically, providing guidance for vertical lifting. When the carrying plate 3 is raised to be flush with the entrance of the processing equipment, the cylinder 12 pushes the protective plate 6 to move horizontally as needed, and the crankcase is properly buffered and positioned through the elastic pressure block 9. The crankcase is then smoothly rolled by a number of rollers 16 on the carrying plate 3 to complete the loading, thereby completing a series of work.
