Description

Technical Field

[0001] This utility model relates to a pump shaft production equipment, and more particularly to an automated cleaning equipment for pump shaft production. Background Technology

[0002] The water pump shaft is one of the core components of a water pump. Its main function is to transmit the torque input from the engine to the impeller and fan, providing them with the energy needed to perform their work. Its manufacturing process generally includes: initial machining, heat treatment, finish machining, keyway milling, cleaning, and inspection. The cleaning process is specifically designed to remove residual metal debris and heavy oil stains from the shaft. To improve production efficiency and automation, and to save labor costs, the water pump shaft manufacturing industry urgently needs to develop equipment that can automate the cleaning of water pump shafts. Summary of the Invention

[0003] This invention provides an automated cleaning equipment for pump shaft production, solving the problem of insufficient efficiency in the existing pump shaft cleaning process.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: an automated cleaning equipment for water pump shaft production, comprising:

[0005] The shaft conveyor belt consists of a first sprocket, a first chain plate, a first chain shaft, and two rubber rollers coaxially fixed on the first chain shaft. The first chain shaft is rotatably connected to the first chain plate. One end of the first chain shaft extends outward and is coaxially fixed with a first gear. The upper segments of the shaft conveyor belt are horizontally distributed.

[0006] The brush chain belt consists of a second sprocket, a second chain plate, a second chain shaft, and a brush roller coaxially fixed on the second chain shaft. The second chain shaft is rotatably connected to the second chain plate. One end of the second chain shaft extends outward and is coaxially fixed with a second gear. The lower segments of the brush chain belt are parallel and spaced above the shaft conveyor chain belt. The circulation directions of the brush chain belt and the shaft conveyor chain belt are the same.

[0007] A double-sided rack is fixed horizontally between the brush chain and the shaft conveyor chain. Racks are provided on its upper and lower sides respectively. When the first gear and the second gear move and come into contact with the double-sided rack, the two gears can achieve rolling engagement with the corresponding racks.

[0008] The spray assembly consists of a spray pipe and a spray head, and is entirely covered above the brush chain belt;

[0009] A drive assembly for driving the first sprocket and the second sprocket to rotate in the same direction;

[0010] The feeding mechanism is located at the front end of the conveyor chain of the shaft;

[0011] The feeding slide rail is located at the rear end of the shaft conveyor chain.

[0012] The working principle of this utility model is as follows: the spray assembly continuously sprays cleaning agent downwards, covering the entire shaft conveyor chain; the feeding mechanism can intermittently feed the water pump shafts to be cleaned onto the shaft conveyor chain; the area between every two first chain shafts on the shaft conveyor chain can be used to place the water pump shafts; four rubber rollers on every two first chain shafts are used to roll and support the water pump shafts; during the uniform speed operation of the shaft conveyor chain, when the first gear meshes with the double-sided rack, the first gear will drive the first chain shafts to rotate synchronously, thus the first chain shafts located on the upper segment of the shaft conveyor chain will maintain a rotating state, thereby driving the water pump shafts in the opposite direction. Similarly, the brush rollers on the lower segment of the brush chain also rotate during operation. Since the brush chain and the shaft conveyor chain have the same circulation direction, their adjacent sides move in opposite directions. That is, the shaft conveyor chain drives the water pump shaft to move backward, while the brush rollers on its upper side move in the opposite direction. When the brush rollers contact the water pump shaft, they can remove oil and debris from the shaft surface through rotation. Furthermore, during the return journey, the brush rollers pass through the spray assembly again, achieving a cleaning effect. Therefore, as the water pump shaft is transported backward, the corresponding brush rollers become cleaner, thus ensuring a good cleaning effect. Finally, the cleaned brush rollers roll off the shaft conveyor chain onto the unloading rail.

[0013] Furthermore, the feeding mechanism includes a discharge ramp, a feeding ramp, a motor, and a transfer plate. An arc surface connects the rear end of the discharge ramp and the front end of the feeding ramp. This arc surface is concentrically arranged with the transfer plate. Several slots are arranged in a circular array on the circumferential sidewall of the transfer plate. The motor drives the transfer plate to rotate at a constant speed. The feeding principle of the feeding mechanism is as follows: Several pump shafts to be cleaned are arranged on the discharge ramp. Because the entire structure is tilted backward, the pump shafts tend to roll downward until they contact the transfer plate. The transfer plate rotates at a constant speed. When the slots on the transfer plate rotate to the position of the pump shaft, the pump shaft can roll into the slot and move along the arc surface with the transfer plate until it enters the feeding ramp. The feeding ramp is also tilted backward, so the pump shaft can roll off the feeding ramp onto the shaft conveyor belt.

[0014] Furthermore, this invention also includes a single-sided rack, which is horizontally fixed above the double-sided rack. The second gear located on a segment of the brush chain can mesh with the single-sided rack. Through this technical solution, when the second gear meshes with the single-sided rack, it can drive the brush roller to rotate, thus enhancing the cleaning effect and ensuring that debris on the brush is thoroughly rinsed away.

[0015] Therefore, this utility model has the following characteristics compared with the prior art: 1. The water pump shaft is transported by a shaft conveyor chain. During the transport process, the water pump shaft is in a rotating state. At the same time, the brush chain on the upper side can drive the brush roller to move in a cycle. The direction of movement of the brush roller is opposite to that of the water pump shaft. At the same time, the brush roller is also in a rotating state. Therefore, the water pump shaft can be cleaned better. The feeding mechanism realizes automated feeding. The whole equipment has a high degree of automation. Attached Figure Description

[0023] Example 1: See Figure 1 and Figure 5 An automated cleaning device for pump shaft production, comprising: a frame;

[0024] See Figure 2The shaft conveyor chain 100 is composed of a first sprocket 110, a first chain piece 120, a first chain shaft 130 and two rubber rollers 140 coaxially fixed on the first chain shaft. The first chain shaft is rotatably connected to the first chain piece. One end of the first chain shaft extends outward and is coaxially fixed with a first gear 150. The upper section of the shaft conveyor chain is horizontally distributed.

[0025] See Figure 2 The brush chain belt 200 is composed of a second sprocket 210, a second chain plate 220, a second chain shaft 230, and a brush roller 240 coaxially fixed on the second chain shaft. The second chain shaft is rotatably connected to the second chain plate. One end of the second chain shaft extends outward and is coaxially fixed with a second gear 250. The lower segments of the brush chain belt are parallel and spaced above the shaft conveyor chain belt. The frame is equipped with a drive assembly that drives the first sprocket and the second sprocket to rotate in the same direction, so that the circulation direction of the brush chain belt and the shaft conveyor chain belt is consistent. The main power source of the drive assembly is two low-speed motors, which drive the first sprocket and the second sprocket respectively.

[0026] The double-sided rack 300 is fixed horizontally between the brush chain and the shaft conveyor chain. Racks 310 are respectively provided on its upper and lower sides. When the first gear and the second gear move and contact the double-sided rack, the two gears can achieve rolling engagement with the corresponding racks.

[0027] The spray assembly 400 consists of a spray pipe 410 and a spray head 420, and is completely covered above the brush chain. The spray pipe is connected to a pumping assembly, which can continuously pump cleaning liquid into the spray pipe.

[0028] The feeding mechanism 500 is located at the front end of the shaft conveyor chain;

[0029] The feeding slide rail 600 is located at the rear end of the shaft conveyor chain.

[0030] See Figure 4The working principle of this embodiment is as follows: the spraying assembly continuously sprays cleaning agent downwards, covering the entire shaft conveyor chain. The feeding mechanism can periodically feed the water pump shafts 10 to be cleaned onto the shaft conveyor chain. The area between every two first chain shafts on the shaft conveyor chain can be used to place the water pump shaft. The four rubber rollers on every two first chain shafts are used to roll and support the water pump shaft. During the uniform speed operation of the shaft conveyor chain, when the first gear meshes with the double-sided rack, the first gear will drive the first chain shaft to rotate synchronously. Therefore, the first chain shaft located on the upper segment of the shaft conveyor chain will remain in a rotating state, thereby driving the water pump shaft to rotate in the opposite direction. Similarly, the brush rollers on the lower segment of the brush chain also rotate during operation. Since the brush chain and the shaft conveyor chain have the same circulation direction, their adjacent sides move in opposite directions. That is, the shaft conveyor chain drives the water pump shaft to move backward, while the brush rollers on its upper side move in the opposite direction. When the brush rollers contact the water pump shaft, they can remove oil and debris from the shaft surface through rotation. Furthermore, during the return journey, the brush rollers pass through the spray assembly again, achieving a cleaning effect. Therefore, as the water pump shaft is transported backward, the corresponding brush rollers become cleaner, thus ensuring a good cleaning effect. Finally, the cleaned brush rollers roll off the shaft conveyor chain onto the unloading rail.

[0031] See Figure 1 The feeding mechanism includes a discharge ramp 510, a feeding ramp 520, a motor, and a transfer plate 530. The discharge ramp, feeding ramp, and motor are all fixed to the frame. An arc surface 540 connects the rear end of the discharge ramp to the front end of the feeding ramp. The arc surface is concentric with the transfer plate. Several slots 531 are distributed in a circular array on the circumferential sidewall of the transfer plate. The motor drives the transfer plate to rotate at a constant speed. The feeding principle of the feeding mechanism is as follows: Several pump shafts to be cleaned are arranged on the discharge ramp. Because the entire structure is tilted backward, the pump shafts tend to roll downward until they contact the transfer plate. The transfer plate rotates at a constant speed. When the slots on the transfer plate rotate to the position of the pump shaft, the pump shaft can roll into the slot and move along the arc surface with the transfer plate until it enters the feeding ramp. The feeding ramp is also tilted backward, so the pump shaft can roll off the feeding ramp onto the shaft conveyor belt.

[0032] See Figure 3 In this embodiment, a single-sided rack 700 is also provided, which is horizontally fixed above the double-sided rack. The second gear located on the segment of the brush chain can mesh with the single-sided rack. Through the above technical solution, when the second gear meshes with the single-sided rack, it can drive the brush roller to rotate, which can enhance the cleaning effect and ensure that the debris on the brush is washed away.

[0033] See Figure 1 This embodiment also includes a waste liquid collection tank 800, the bottom of which is provided with a waste liquid outlet 810 and a filter 820 located on the upper side of the waste liquid outlet.

[0034] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
