Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts production equipment, specifically a grease spraying device for casting transmission housings. Background Technology

[0002] The transmission housing is an important component of the transmission. It is usually made of high-strength aluminum alloy or cast iron and has a complex structure and high-precision machining requirements. It is mainly used to house and protect various gears, shafts, bearings, synchronizers and other components inside the transmission, providing them with a stable mounting position and a good working environment. At the same time, it can withstand various forces and torques generated during transmission operation. The transmission housing also plays a sealing role to prevent lubricating oil leakage and ensure normal lubrication and heat dissipation of the transmission. In addition, the housing usually has various mounting holes, oil passages, vents and other structures to meet the connection requirements of the transmission with the engine, drive shaft and other components, as well as the functions of lubrication and heat dissipation.

[0003] A search revealed Chinese patent publication number CN211275095U, which discloses a grease spraying device for casting transmission housings. During the spraying process, the transmission housing is simply placed between the lower and upper mesh frames and secured by fixing rings and blocks. Lacking a dedicated clamping mechanism, it is difficult to accurately and stably position and clamp transmission housings of different sizes and shapes. When the rotating platform drives the housing to rotate for spraying, the housing is prone to shaking or even displacement, leading to deviations in the grease spraying position and uneven spraying, affecting the spraying quality and subsequent casting process. Furthermore, this fixing method has poor versatility and cannot meet the reliable fixing requirements of diverse transmission housings, limiting the device's application range and production efficiency.

[0021] Reference Figures 1 to 4In this embodiment of the present invention, a grease spraying device for casting a transmission housing includes: a housing 1, a rotating plate 2 connected to the inner side of the housing 1, the rotating plate 2 being driven by a motor on the outer side of the housing 1, an electric push rod 3 inside the rotating plate 2, a push block 4 fixedly connected to the pushing end of the electric push rod 3; a movable block 5 is provided in a slot on the outer side of the rotating plate 2, a push limiting groove 6 is provided on the inner side of the movable block 5, a push limiting block 7 is fixedly connected to the side of the push block 4; a sliding limiting groove 8 is provided in a slot on one side of the rotating plate 2, a sliding limiting block 9 is fixedly connected to the side of the movable block 5, the contact surface between the push block 4 and the movable block 5 is an inclined surface, and the push limiting block 7 is adapted to the sliding limiting groove 8, the sliding limiting groove 8 is adapted to the sliding limiting block 9, and a clamping claw 10 is fixedly connected to the side of the movable block 5. The device comprises a rotating plate 2, an electric push rod 3, a push block 4, and a movable block 5. The clamping mechanism, consisting of the push limiting groove 6, the push limiting block 7, the sliding limiting groove 8, the sliding limiting block 9, and the clamping claw 10, is provided in two sets, symmetrically arranged on both upper sides inside the housing 1. Each set of clamping mechanisms has two sets of movable blocks 5. The working principle is as follows: after the transmission housing to be sprayed is placed in the designated position between the two sets of clamping mechanisms, the electric push rod 3 is activated, and its pushing end drives the push block 4 to move backward. Using the inclined contact surface between the push block 4 and the movable block 5, the linear motion of the push block 4 is converted into the lateral sliding of the movable block 5 in the slot on the outside of the rotating plate 2. During this process, the push limiting block 7 slides in the sliding limiting groove 8, and the sliding limiting block 9 plays a guiding role in the sliding limiting groove 8 to ensure the stable movement of the movable block 5. The movable blocks 5 on both sides drive the clamping claw 10 to move towards each other, thereby achieving a firm clamping of the transmission housing.

[0022] A recovery chamber 11 is provided inside the housing 1. A lower oil mesh 12 is fixedly connected to the upper end of the recovery chamber 11. A splash guard side 13 is fixedly connected to the upper end of the outer side of the housing 1. An oil drain port 14 is provided inside the splash guard side 13. The lower oil mesh 12 is located below the clamping mechanism, and the oil drain port 14 extends through the recovery chamber 11. During the grease spraying process, the splash guard side 13 blocks the splashed excess grease. The grease flows downward through the oil drain port 14 inside the splash guard side 13, is filtered by the lower oil mesh 12, and enters the recovery chamber 11.

[0023] A top plate 15 is fixed to the top of the housing 1 via four sets of support rods. An atomizing nozzle 16 is fixed below the top plate 15. An oil reservoir 17 is fixed above the top plate 15. A return oil pipe 18 is fixed to the side of the oil reservoir 17. One end of the return oil pipe 18 is connected to the oil pump inside the oil reservoir 17, and the other end is connected to the inside of the recovery chamber 11. When the housing is clamped and fixed, the motor on the outside of the housing 1 drives the rotating plate 2 to rotate at a constant speed inside the housing 1, thereby driving the transmission housing to rotate synchronously. At the same time, the oil pump on the side of the oil reservoir 17 pumps oil from the reservoir. Grease is transported to the top plate 15 via the return oil pipe 18, and then atomized by the atomizing nozzle 16 below the top plate 15, and evenly sprayed onto the rotating transmission housing surface. Finally, the return oil pipe 18 draws the grease in the recovery chamber 11 back to the storage tank 17, realizing the recycling of grease. After the spraying operation is completed, the electric push rod 3 retracts in the reverse direction, driving the push block 4 to move back, so that the movable block 5 and the clamping claw 10 are reset and the housing is released. The motor starts again, driving the rotating plate 2 to rotate and send out the sprayed transmission housing for the next spraying operation.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] The working principle of this utility model is as follows: The transmission housing is placed at a designated position between two clamping mechanisms consisting of a rotating plate 2, an electric push rod 3, a pushing block 4, a movable block 5, a pushing limit groove 6, a pushing limit block 7, a sliding limit groove 8, a sliding limit block 9, and a clamping claw 10. The electric push rod 3 is activated, and its pushing end drives the pushing block 4 to move backward. The inclined contact surface between the pushing block 4 and the movable block 5 allows the movable block 5 to slide laterally in the groove on the outside of the rotating plate 2. The pushing limit block 7 slides in cooperation within the sliding limit groove 8, and the sliding limit block 9 is guided within the sliding limit groove 8. The movable blocks 5 on both sides drive the clamping claw 10 to move towards each other to complete the clamping of the transmission housing. Then, the motor on the outside of the housing 1 drives the rotating plate 2... The shell rotates at a constant speed. The oil pump on the side of the oil tank 17 delivers grease to the top plate 15 via the return oil pipe 18. The grease is then atomized by the atomizing nozzle 16 below the top plate 15 and evenly sprayed onto the rotating shell surface. During the spraying process, the splash guard 13 blocks excess splashed grease, which flows down through the internal oil drain 14. After being filtered by the lower oil screen 12 at the upper end of the recovery chamber 11, the grease in the recovery chamber 11 is drawn back to the oil tank 17 via the return oil pipe 18 for recycling. When the spraying operation is completed, the electric push rod 3 retracts in the reverse direction, pushing the block 4 back to reset the movable block 5 and the clamping claw 10, releasing the shell. The motor then drives the rotating plate 2 to rotate again and send out the sprayed shell, ready for the next spraying.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
