Description

Technical Field

[0001] This utility model relates to the field of linear conveyor technology, specifically to a conveyor line for surface treatment of constant velocity universal joint parts. Background Technology

[0002] A constant velocity joint (CV joint) is a mechanical device in an automotive transmission system that achieves constant velocity transmission. It primarily addresses the problem of power transmission when the angle changes. Its core function is to maintain the same angular velocity between the output and input shafts, preventing speed fluctuations and vibrations caused by changes in transmission angle. A CV joint consists of multiple parts, including a bell-shaped housing, a star-shaped sleeve, steel balls, and a cage. These parts work together to ensure constant velocity transmission at various angles.

[0003] The bell-shaped shell, star-shaped sleeve, steel ball, and cage of the universal joint are all metal parts. The manufacturing process includes forging, turning, milling, drilling, precision grinding, cleaning, and assembly. In the existing technology, the surface of the parts is usually cleaned only before assembly. However, in the preceding process steps, there are metal shavings, particles, dust and other substances on the surface of the parts. If cleaning is only carried out at the end, the surface quality can easily be affected by the metal shavings, particles, dust and other substances attached to the surface during the transfer between intermediate steps and during the processing. For example, it can cause scratches, affect the accuracy, and affect optical quality inspection. Utility Model Content

[0004] This invention provides a constant velocity universal joint parts surface treatment conveyor line, which is used to clean metal shavings, particles, dust and other substances attached to the surface of parts in a timely and preliminary manner during the conveying of adjacent processes, thereby reducing the adverse effects on the processing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A constant velocity universal joint parts surface treatment conveying line includes a mesh chain conveyor for conveying parts via a conveying mesh chain. Air supply pipes are respectively provided above the frame and inside the frame of the mesh chain conveyor. The air supply pipes are parallel to the conveying direction of the mesh chain. The air supply pipe inside the frame of the mesh chain conveyor is located between the upper and lower chains of the conveying mesh chain. The two air supply pipes are staggered along the conveying direction of the mesh chain.

[0007] Multiple rotating nozzles facing the conveyor belt are equidistantly installed on the air supply pipe. Multiple flat nozzles are obliquely installed on the air blowing surface of the rotating nozzles, and the multiple flat nozzles on each rotating nozzle are arranged in a ring array.

[0008] Preferably, two air supply pipes are fixedly installed on the top of the frame and inside the frame of the mesh conveyor by multiple fixing brackets and multiple fixing rods, respectively. The fixing brackets and fixing rods are located on the corresponding air supply pipes near the rotating nozzles.

[0009] Preferably, the rotating nozzle inside the mesh conveyor is fixed above the mesh conveyor frame by a support frame with a fixed groove that is perpendicular to the conveying direction of the mesh conveyor and has a downward opening. The height of the fixed groove, the support frame, the fixed frame, and the bottom flat nozzle of the rotating nozzle above the mesh conveyor are all higher than the height of the part.

[0010] Preferably, two upper guide plates are symmetrically fixed in the fixed groove. The lower edges of the two upper guide plates intersect each other and the upper edges extend to the top of the inner wall at both ends of the fixed groove, and the edges of the upper guide plates are connected to the inner wall of the fixed groove.

[0011] Preferably, air outlets are provided on both sides of the frame of the mesh conveyor corresponding to the rotating nozzle above the mesh conveyor. The air outlets are located between the upper and lower chains of the conveying mesh chain, and a connecting groove perpendicular to the conveying direction of the mesh chain and with its opening facing upward is fixed between the air outlets and the inner walls of both sides of the frame of the mesh conveyor.

[0012] Preferably, two lower guide plates are symmetrically fixed inside the connecting groove. The upper edges of the two lower guide plates intersect each other and the lower edges extend to the bottom of the air outlet, and the edges of the lower guide plates are connected to the inner wall of the connecting groove.

[0013] Preferably, one end of each of the two air supply pipes is fitted with a plug and the other end is connected to an industrial fan. The end of the air supply pipe inside the frame of the mesh conveyor that is away from the plug passes through the frame and extends to the outside of the frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention uses a mesh conveyor to transport parts between adjacent processes or workstations. Air is supplied to rotating nozzles through an air supply pipe provided by an industrial fan or air pump. Two sets of rotating nozzles above and below the upper chain of the conveyor mesh rotate while blowing air, blowing air onto the conveyor mesh and the upper and lower surfaces of the parts, causing the adhering substances on the surface of the parts to fall off, achieving a preliminary cleaning effect. At the same time, the conveyor mesh is also cleaned. By cleaning the parts in a timely manner, the product quality can be improved. Attached Figure Description

[0024] 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.

[0025] like Figure 1-7 As shown, this utility model provides a technical solution: a constant velocity universal joint parts surface treatment conveying line, including a mesh chain conveyor 3 that conveys parts 2 through a conveying mesh chain 1. Air supply pipes 4 are respectively provided above the frame and inside the frame of the mesh chain conveyor 3. One end of the two air supply pipes 4 is fitted with a plug, and the other end is connected to an industrial fan, air pump or other pressure air generating equipment. The end of the air supply pipe 4 inside the frame of the mesh chain conveyor 3 away from the plug passes through the frame and extends to the outside of the frame.

[0026] The air supply pipe 4 is parallel to the conveying direction of the conveyor chain 1. The air supply pipe 4 inside the frame of the mesh chain conveyor 3 is located between the upper and lower chain belts of the conveyor chain 1. The two air supply pipes 4 are staggered along the conveying direction of the conveyor chain 1. The upper blowing dust removal and the lower blowing dust removal positions are staggered to avoid the wind force canceling out and affecting the dust removal effect.

[0027] Multiple rotating nozzles 5 are equidistantly installed on the air supply pipe 4, facing the upper chain belt of the conveyor belt 1. The rotating nozzles 5 can be purchased directly on the market. They are equipped with a spiral component inside. When squeezed by fluid, that is, when squeezed by air, they can rotate along with the air supply. Multiple flat nozzles 6 are installed obliquely on the air blowing surface of the rotating nozzles 5, and the multiple flat nozzles 6 on each rotating nozzle 5 are arranged in a ring array. By rotating and blowing, the surface of the part 2 can be blown in all directions, avoiding the existence of cleaning dead corners.

[0028] Two air supply pipes 4 are fixedly installed on the top of the frame and inside the frame of the mesh conveyor 3 by multiple fixing brackets 7 and multiple fixing rods 8. The fixing brackets 7 and fixing rods 8 are located on the corresponding air supply pipes 4 near the rotating nozzles 5. When the rotating nozzles 5 rotate, there is vibration. By installing and fixing the air supply pipes 4 with the fixing brackets 7 and fixing rods 8, the vibration of the air supply pipes 4 and the rotating nozzles 5 can be reduced.

[0029] The rotating nozzle 5 inside the mesh conveyor 3 is fixed above the frame of the mesh conveyor 3 by a support frame 9. The fixed groove 10 is perpendicular to the conveying direction of the conveying mesh chain 1 and has an opening facing downward. The height of the fixed groove 10, the support frame 9, the fixed frame 7, and the flat nozzle 6 at the bottom of the rotating nozzle 5 above the mesh conveyor 3 are all higher than the height of part 2. All components are designed based on the existing mesh conveyor 3 and are offset from the original internal mesh chain rollers, frame reinforcement frames, and other components (the original components are not shown in the figure) to avoid interfering with the drive conveying.

[0030] Two upper guide plates 11 are symmetrically fixed inside the fixed groove 10. The lower edges of the two upper guide plates 11 intersect each other and the upper edges extend to the top of the inner walls at both ends of the fixed groove 10. The edges of the upper guide plates 11 are connected to the inner walls of the fixed groove 10. They guide and exhaust air to the upper sides of the mesh conveyor 3 to prevent dust and debris blown upward from falling back down onto the upper chain belt of the conveyor mesh 1 and parts 2 due to gravity, thus avoiding ineffective cleaning.

[0031] The rotating nozzle 5 above the mesh conveyor 3 is provided with air outlets 12 on both sides of the frame of the mesh conveyor 3. The air outlets 12 are located between the upper and lower chains of the conveying mesh chain 1, and the air outlets 12 are fixed with connecting grooves 13 that are perpendicular to the conveying direction of the conveying mesh chain 1 and have upward openings between the inner walls of the frame on both sides of the mesh conveyor 3.

[0032] Two lower guide plates 14 are symmetrically fixed inside the connecting groove 13. The upper edges of the two lower guide plates 14 intersect each other and the lower edges extend to the bottom of the air outlet 12 respectively. The edges of the lower guide plates 14 are connected to the inner wall of the connecting groove 13 to guide and exhaust air to both sides of the mesh conveyor 3, so as to avoid the air falling directly down onto the lower chain of the conveyor mesh 1 and causing ineffective cleaning of the conveyor mesh 1.

[0033] Working principle:

[0034] The conveyor belt 1 of the mesh conveyor 3 transports part 2 from left to right to the adjacent processing station. During the conveying process, the air supply pipe 4 rotates and blows air through the rotating nozzle 5 and the flat nozzle 6, blowing air on the upper and lower surfaces of the conveyor belt 1 and the upper and lower surfaces of part 2 to clean surface dust and impurities. The blown air and the dust and impurities carried away are blown to both sides of the mesh conveyor 3 by the upper guide plate 11 and the lower guide plate 14, so that part 2 is cleaned in a timely and preliminary manner between adjacent processes, avoiding long-term adhesion to paper making and affecting processing accuracy and inspection accuracy, thereby improving the product quality of part 2 to a certain extent.
