Description

Technical Field

[0001] This utility model relates to the field of bar stock processing technology, and more specifically, to a bar stock outer diameter finishing device. Background Technology

[0002] In the field of machining, the finishing of the outer diameter of bar stock has always been an important process. The finishing of the outer diameter of bar stock is used to reduce surface roughness and make the outer diameter of the bar stock smooth. The accuracy of the outer diameter of the bar stock after machining has extremely strict requirements for the assembly of its parts.

[0003] A search revealed Chinese patent CN220074123U, which discloses a bar stock processing equipment. Addressing the issue that current processing devices, due to increased automation, are typically equipped with robotic arms that slide on a truss mounted on two grinding machines, require disassembly for relocation, leading to inconvenience in both moving and reassembly. This new equipment addresses this problem by using a floor-mounted truss with a first and second grinding machine on either side. The first and second robotic arm components can simultaneously grip and load the corresponding workpieces onto these two grinding machines for processing, resulting in high efficiency. Furthermore, the crossbeams are fixed to the floor-mounted truss, facilitating relocation. The entire truss can be moved during relocation without disassembly, reducing the installation requirements for the first and second grinding machines.

[0004] In the grinding process of this bar stock processing equipment, the grinding wheel rotates at high speed and comes into contact with the bar stock. Due to the high grinding speed and intense friction, a lot of heat is generated. Relying solely on natural cooling or simple air cooling cannot quickly and evenly reduce the temperature of the bar stock. Excessive temperature will cause thermal deformation of the bar stock, damaging its dimensional and shape accuracy, making it difficult to guarantee the dimensional and shape accuracy of the bar stock. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides a bar stock outer diameter finishing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bar stock outer diameter finishing device, comprising a processing table, a bar stock fixing machine fixedly installed on the top of the processing table, and a processing cooling mechanism provided on the side of the top of the processing table near the bar stock fixing machine.

[0007] The processing and cooling mechanism includes an electric slide table, which is fixed to the top of the processing table. A movable table is slidably connected to the top of the electric slide table. A fixed block is fixedly installed on the top of the movable table. A bar grinding head is fixedly installed on one side of the fixed block. A water pipe is provided on one side of the fixed block. A connecting water pipe is fixedly connected inside the fixed block. The water pipe and the connecting water pipe are connected. An atomizing nozzle is fixedly installed on one side of the water pipe. A water tank is provided at one end of the connecting water pipe. A water pump is fixedly installed between the connecting water pipe and the water tank. A water replenishment pipe is fixedly connected to the top of the water tank. A dust collection mechanism is provided on the outside of the fixed block.

[0008] Preferably, the dust collection mechanism includes a dust collection box, which is fixed to the top of the processing table. A telescopic hose is fixedly connected to one side of the dust collection box, and a protective cover is fixedly connected to one end of the telescopic hose. A filter screen is fixedly installed on one side of the protective cover.

[0009] Preferably, the bottom of the dust collection box extends through the processing table and to the bottom of the processing table, and an exhaust fan is fixedly installed at the bottom of the dust collection box.

[0010] Preferably, a dust discharge pipe is fixedly connected to the bottom of the dust collection box, the top of the dust discharge pipe passes through the dust collection box and extends into the interior of the dust collection box, and a valve is fixedly installed inside the dust discharge pipe.

[0011] Preferably, one end of the connecting water pipe passes through the fixing block and extends to one side of the fixing block, and the number of atomizing nozzles is set to multiple.

[0012] Preferably, the number of the dust collection box, the telescopic hose, and the protective cover is set to two.

[0013] Preferably, the protective cover has an arc-shaped cross-section and is a hollow structure.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up a processing cooling mechanism, the temperature during the grinding process can be effectively reduced by spraying coolant through atomizing nozzles, preventing the bar stock from deforming due to overheating, ensuring the dimensional and shape accuracy of the bar stock, and avoiding minor deformation of the bar stock during grinding that could prevent parts from being properly assembled or used. Multiple atomizing nozzles can provide uniform cooling to the processing area, making the surface temperature distribution of the bar stock more uniform, further improving processing accuracy, and improving shape accuracy indicators such as the cylindricity of the outer circle of the bar stock.

[0016] 2. By setting up a dust collection mechanism, dust and debris generated during processing can be cleaned up in a timely manner, avoiding the impact of dust accumulation on the continuity of processing. This reduces the number of interruptions in the processing process and improves processing efficiency. The combined use of the protective cover and the dust collection mechanism can effectively collect dust and debris generated during processing, reducing pollution to the working environment. The filter screen can prevent larger particles of debris from entering the dust collection box, reducing the risk of operators inhaling dust and protecting the health of operators.

A movable table 4 is slidably connected to the top of the electric slide table 3. A fixed block 5 is fixedly installed on the top of the movable table 4. A bar grinding head 6 is fixedly installed on one side of the fixed block 5. A water pipe 7 is provided on one side of the fixed block 5. A connecting water pipe 8 is fixedly connected inside the fixed block 5. The water pipe 7 and the connecting water pipe 8 are connected. An atomizing nozzle 9 is fixedly installed on one side of the water pipe 7. A water tank 11 is provided at one end of the connecting water pipe 8. A water pump 10 is fixedly installed between the connecting water pipe 8 and the water tank 11. A water supply pipe 12 is fixedly connected to the top of the water tank 11. A dust collection mechanism is provided on the outside of the fixed block 5.

[0027] As attached Figure 1 , 2 As shown in Figures 3 and 5, the dust collection mechanism includes a dust collection box 13, which is fixed to the top of the processing table 1. A telescopic hose 14 is fixedly connected to one side of the dust collection box 13, and a protective cover 15 is fixedly connected to one end of the telescopic hose 14. A filter screen 16 is fixedly installed on one side of the protective cover 15 to filter larger debris. The bottom of the dust collection box 13 penetrates through the processing table 1 and extends to the bottom of the processing table 1. An exhaust fan 17 is fixedly installed at the bottom of the dust collection box 13, and a dust discharge pipe 18 is fixedly connected to the bottom of the dust collection box 13. The top of the dust discharge pipe 18 penetrates through the dust collection box 13 and extends into the interior of the dust collection box 13. A valve 19 is fixedly installed inside the dust discharge pipe 18 to facilitate the suction of dust generated during processing. At the same time, the dust can be collected and discharged through the dust discharge pipe 18.

[0028] As attached Figure 2 , 3 As shown in Figures 4 and 6, one end of the water pipe 8 passes through the fixing block 5 and extends to one side of the fixing block 5. The number of atomizing nozzles 9 is set to multiple to improve the cooling effect.

[0029] As attached Figure 1 , 2 As shown in Figures 3 and 5, the number of dust collection box 13, telescopic hose 14 and protective cover 15 are all set to two. The cross-sectional shape of the protective cover 15 is set to arc shape. The protective cover 15 has a hollow structure to improve the dust collection effect and allow dust to enter the dust collection box 13 through the protective cover 15 and telescopic hose 14.

[0030] Working principle of this utility model: In the use of the bar stock outer diameter precision machining device provided by this utility model, the bar stock to be processed is fixed on the bar stock fixing machine table 2 to ensure that the bar stock will not move during the processing. When the processing is started, the bar stock grinding head 6 grinds the bar stock. Since a lot of heat is generated during the grinding process, the cooling system is started at this time. The water pump 10 works and delivers the cooling water in the water tank 11 to the connecting water pipe 8 in the fixing block 5 through the connecting water pipe 8. The cooling water flows from the connecting water pipe 8 into the water pipe 7, and then is sprayed out through multiple atomizing nozzles 9. The atomizing nozzles 9 atomize the cooling water into tiny particles and spray them evenly onto the bar stock grinding area to quickly remove the heat generated by the grinding, reduce the temperature of the bar stock and the grinding head, ensure the processing accuracy, and prevent the bar stock from deforming due to overheating. The electric slide table 3 can drive the moving table 4 and the fixing block 5 and the bar stock grinding head 6 fixed on it to move in a specific direction to realize the processing of different positions of the bar stock.

[0031] During processing, a large amount of dust and debris are generated. The exhaust fan 17 is started, creating negative pressure in the dust collection box 13. A protective cover 15, connected to the dust collection box 13 via a telescopic hose 14, covers the processing area. Because the protective cover 15 is arc-shaped and hollow, it can better fit the bar stock and surround the processing area, preventing dust and debris from spreading to the surroundings. Under the action of negative pressure, the dust and debris are filtered by the filter screen 16 on one side of the protective cover 15 and then sucked into the dust collection box 13 through the telescopic hose 14. When the dust in the dust collection box 13 accumulates to a certain level, the valve 19 inside the dust discharge pipe 18 can be opened to discharge the dust for centralized treatment.

[0032] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
