[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] This application provides a precision mechanical parts polishing machine, mainly used to solve the problem that the polishing process of cylindrical precision parts is often slow and requires manual loading and unloading, which limits the capacity for mass production. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-11 Please provide a detailed explanation:

[0042] A precision mechanical parts processing and polishing machine mainly includes: a rough grinding mechanism 1, which includes a rough grinding box 11 and a rough grinding assembly 12 disposed inside the rough grinding box 11. The rough grinding assembly 12 includes a grinding part 121 and an assisting rotation part 122 respectively disposed on the top and bottom walls of the rough grinding box 11. The grinding part 121 is responsible for preliminary grinding of the surface of the parts, and the assisting rotation part 122 is used to assist the mechanical parts to rotate so as to achieve comprehensive grinding; and a fine grinding mechanism 2, which includes a fine grinding box 21 disposed on one side of the rough grinding box 11 and a fine grinding assembly 22 disposed inside the fine grinding box 21. The fine grinding box 21 and the rough grinding box 11 have a through-connecting processing channel in the middle to ensure a smooth transition of the parts from rough grinding to fine grinding. The grinding assembly 22 is used for fine grinding of mechanical parts. The fine grinding assembly 22 includes two adjusting members 221 located on the same horizontal line and several fine grinding rollers 222 arranged in a rotating array. The two adjusting members 221 control the fine grinding rollers 222 to move closer or further apart, adjusting the distance between them to accommodate parts of different sizes and achieve precise clamping. The circulating material conveying mechanism 3 consists of two symmetrically arranged components. Each circulating material conveying mechanism 3 includes two support frames 31 located on opposite sides of the coarse grinding box 11 and the fine grinding box 21. A vertical support rod 32 is rotatably mounted on the top of each support frame 31, and a transmission wheel 33 is fixed to the top of each support rod 32. Two transmission wheels 33... A transmission belt 34 is fitted between the driving wheels 33, and the transmission belt 34 passes through the processing channel. Several evenly distributed clamping members 35 are fixed on the outer periphery of the transmission belt 34. The clamping members 35 on the two transmission belts 34 correspond one-to-one. One of the support frames 31 is equipped with a driving member 36 for driving the support rod 32 to rotate. The two corresponding clamping members 35 are used to clamp the mechanical parts. The circulating material conveying mechanism 3 also includes a limiting member 37 for limiting the clamping members 35 on the same transmission belt 34. The clamping members 35 fixed on the transmission belt 34 are used to clamp and transfer the mechanical parts. The limiting member 37 ensures the stability of the clamping members 35 during the transmission process. When the device is in use, after the mechanical parts are put into the polishing machine, they are clamped by two phases. The corresponding clamping member 35 clamps the part, and the transmission belt 34 drives the clamping member 35 to move. Inside the rough grinding box 11, the grinding part 121 performs rough grinding on the part and assists the rotating part 122 to rotate the part to ensure uniform grinding. After rough grinding, the part moves to the fine grinding box 21 through the processing channel. The fine grinding assembly 22 adjusts the spacing of the fine grinding rollers 222 according to the part size to perform fine grinding. The part is transported back to the terminal position, and the clamping member 35 opens to release the part, completing the entire polishing process. The automated circulating material conveying mechanism 3 significantly reduces the time for manual loading and unloading and improves the processing speed. The coordinated work of the rough grinding mechanism 1 and the fine grinding mechanism 2 ensures high-quality polishing of the part surface. Through automated design, manual operation is reduced and the production process is simplified.

[0043] For details, please refer to Figure 2The clamping component 35 includes a mounting block 351 fixed to the outer periphery of the transmission belt 34. A horizontal electric push rod 352 is fixed on the mounting block 351. A clamping block 353 is rotatably mounted on the output end of the electric push rod 352. The rotatable connection of the clamping block 353 facilitates rotation during rough and fine grinding, improving polishing efficiency. It is designed to drive the clamping block 353 to move horizontally. The cooperation of two corresponding electric push rods 352 realizes the clamping and release of mechanical parts. A rubber friction pad 354 is installed on one end of the clamping block 353 to increase the friction during clamping, ensuring the stability of the mechanical parts during polishing and preventing slippage. In specific operation, the two corresponding electric push rods 352 are activated, causing their output ends to push the clamping block 353. The clamping block 353 and the rubber friction pad 354 clamp the mechanical parts, ready for polishing. When the transmission belt 352 is activated, the mechanical parts are clamped. 4. When rotation begins, the clamping block 353 on the clamping member 35 moves together with the clamped mechanical parts, passing through the processing channel from the rough grinding mechanism 1 to the fine grinding mechanism 2. After polishing is completed, the electric push rod 352 retracts, the clamping block 353 is released, and the rubber friction pad 354 releases the mechanical parts. The parts can then be removed from the polishing machine or enter the next production stage. The precise control of the electric push rod 352 makes the clamping force adjustable, adapting to mechanical parts of different sizes and shapes, reducing damage to the parts. The automated operation of the electric push rod 352 reduces manual intervention, improving the ease and repeatability of operation. The design of the clamping member 35 makes the loading and unloading of mechanical parts faster, shortening the production cycle and improving production efficiency. The use of the rubber friction pad 354 increases the friction during clamping, ensuring the stability of the parts during polishing and improving the polishing quality.

[0044] Further, please refer to Figure 4 and Figure 7 The driving component 36 includes a motor 361 mounted on a support frame 31. A worm gear 362 is fixed to the output end of the motor 361. A worm wheel 363, meshing with the worm gear 362, is fixedly sleeved on the support rod 32. When the transmission belt 34 needs to be driven, the motor 361 is started, and the rotational motion of the motor is transmitted through the worm gear 362. When the worm gear 362 rotates, it drives the worm wheel 363 to rotate through meshing with the worm wheel 363. The rotation of the worm wheel 363 causes the support rod 32, which is fixedly sleeved with it, to rotate, thereby driving the transmission belt. The transmission belt 34 moves, and the movement of the transmission belt 34 drives the clamping component 35 fixed on it to realize the clamping and transportation of mechanical parts. The motor 361 can precisely control the moving speed and acceleration of the bearing rod 32, and realize precise control of the transmission belt 34 and the clamping component 35. The meshing transmission structure of the worm 362 and worm wheel 363 is compact and occupies little space, making it suitable for achieving efficient transmission in a limited space. The transmission of the worm 362 and worm wheel 363 has high transmission efficiency, which can ensure that the power of the motor 361 is effectively transmitted to the bearing rod 32.

[0045] Furthermore, please refer to Figure 1 and Figure 7 The limiting component 37 includes a support frame 371 and a limiting frame 372. The top side of the support frame 371 and the bottom side of the limiting frame 372 are both arranged along the movement trajectory of the transmission belt 34. The transmission belt 34 is located between the top side of the support frame 371 and the bottom side of the limiting frame 372. The mounting block 351 slides between the top side of the support frame 371 and the bottom side of the limiting frame 372. These two components work together to ensure that the transmission belt 34 and the clamping component 35 run stably along the predetermined trajectory. When the bearing rod 32 is driven by the driving component 36, the transmission belt 34 begins to move. The mounting block 351 on the clamping component 35 slides between the support frame 371 and the limiting frame 372. The support frame 371 and the limiting frame 372 restrict the lateral displacement of the transmission belt 34, ensuring that the clamping component 35 correctly clamps and transports mechanical parts. The design of the limiting component 37 ensures the stability of the transmission belt 34 during operation and prevents failures or accidents caused by deviation.

[0046] In this embodiment, please refer to Figure 8 and Figure 9 The grinding section 121 includes an electric push rod 1211 vertically fixed to the top wall inside the coarse grinding box 11. An arc-shaped, downward-opening coarse grinding plate 1212 is fixed to the bottom end of the electric push rod 1211, allowing the coarse grinding plate 1212 to perform vertical grinding on the mechanical parts below. The arc-shaped design of the coarse grinding plate 1212, with its downward opening, facilitates covering a wider area during grinding. The arc design also helps adapt to the surfaces of mechanical parts with different shapes. During operation, the electric push rod 1211 is activated, causing the coarse grinding plate 1212 at its bottom end to... The grinding plate 1212 descends to the position of contact with the mechanical parts. Under the control of the electric push rod 1211, the grinding plate 1212 grinds the mechanical parts vertically to remove burrs and unevenness from the surface. The advantages are: the automatic control of the electric push rod 1211 reduces the time and labor intensity of manual grinding, significantly improving grinding efficiency; the precise control of the electric push rod 1211 ensures that the pressure and position are consistent for each grinding, improving the consistency of grinding quality; and the arc-shaped grinding plate 1212 can adapt to parts of different shapes, increasing the applicability of the grinding section 121.

[0047] Further, please refer to Figure 8 and Figure 9The assisting rotation unit 122 includes an electric push rod 1221 vertically fixed to the bottom wall inside the coarse grinding box 11. A connecting block 1222 is fixed to the top of the electric push rod 1221. An auxiliary roller 1223 is rotatably mounted on the connecting block 1222. A motor 1224 with its output end fixed to one end of the shaft of the auxiliary roller 1223 is mounted on the connecting block 1222. In specific operation, the electric push rod 1221 is started to move upward, positioning the auxiliary roller 1223 at a suitable working height. The top side of the auxiliary roller 1223 is disconnected from the bottom side of the machine. The motor 1224 is started to make the auxiliary roller 1223 start to rotate, assisting the mechanical parts to rotate during the coarse grinding process. With the cooperation of the coarse grinding plate 1212, the mechanical parts are coarsely ground.

[0048] To reduce the impact of dust on human activity and the environment during the coarse grinding process, please refer to [link / reference]. Figure 3 , Figure 5 , Figure 8 and Figure 9 On both opposite sides of the coarse grinding box 11, there are circulation pipes 13. Several suction pipes 14 are connected to the circulation pipes 13 and penetrate into the interior of the coarse grinding box 11. A connecting pipe 15 connects two circulation pipes 13. The other end of the connecting pipe 15 is connected to an external industrial vacuum cleaner. When the mechanical parts are being coarsely ground, the industrial vacuum cleaner is turned on at the same time. During the grinding process, the suction pipes 14 transport dust and debris to the external vacuum cleaner through the circulation pipes 13 and the connecting pipe 15. Through the effective dust collection system, the accumulation of dust in the grinding area is reduced, the working environment is significantly improved, the opportunity for operators to be exposed to dust is reduced, and their respiratory health is protected.

[0049] Please refer to this solution. Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11Two adjusting components 221 are respectively installed on the two vertical inner walls of the grinding box 21. The adjusting component 221 includes a cross mounting bracket 2211 fixed on the inner wall of the grinding box 21. One side of the cross mounting bracket 2211 has four cross-shaped sliding grooves 2212. A rotating disk 2213 is movably arranged on one side of the cross mounting bracket 2211. The rotating disk 2213 has four arc-shaped grooves 2214 arranged in an array. The four arc-shaped grooves 2214 correspond one-to-one with the four sliding grooves 2212. Sliding blocks 2215 are slidably installed inside the sliding grooves 2212. A connecting groove 23 communicating with the sliding grooves 2212 is opened through one side of the grinding box 21. A connecting rod is rotatably installed through the sliding block 2215. 2216, one end of the connecting rod 2216 movably passes through the corresponding arc-shaped groove 2214, and the other end of the connecting rod 2216 movably passes through the connecting groove 23. The rotation of the rotating disk 2213 causes the connecting rod 2216 to slide along the arc-shaped groove 2214, thereby causing the sliding block 2215 to slide along the sliding groove 2212. The four sliding blocks 2215 slide synchronously. The four connecting rods 2216 in the two adjusting components 221 correspond one-to-one. The fine grinding roller 222 is fixedly connected between two corresponding connecting rods 2216, realizing the mutual convergence or diffusion of the four fine grinding rollers 222. A motor 3 2217 is installed on the outer wall of the fine grinding box 21. The output end of the motor 3 2217 movably passes through the fine grinding box 21 and the cross mounting bracket 22. 11. Fixed to the center of the rotating disk 2213, the outer wall of the fine grinding box 21 is constructed with a limiting groove 24 along the length of the sliding groove 2212. Several connecting rods 2216 have motors 2218 that slide inside the limiting groove 24 fixed to their ends for limiting the motors 2218. In specific operation, the two corresponding clamping parts 35 first move the coarsely ground mechanical parts between the four fine grinding rollers 222. By controlling the motors 2217, the rotating disk 2213 is rotated, which in turn drives the arc groove 2214 and the connecting rods 2216 to adjust the position of the fine grinding rollers 222. The four fine grinding rollers 222 clamp the mechanical parts, and the motors 2218 drive the connecting rods 2216 in the sliding groove 2212. The internal sliding mechanism adjusts the grinding pressure by changing the distance between the grinding roller 222 and the workpiece. After the grinding roller 222 is adjusted to the appropriate position and pressure, the motor 2218 of the grinding box 21 is started, driving the grinding roller 222 to rotate and perform fine grinding on the mechanical parts. The advantages of this component are: the design of the adjusting component 221 allows for precise adjustment of the position and pressure of the grinding roller 222 to accommodate mechanical parts of different sizes and shapes; the driving method of the motors 2217 and 2218 makes the adjustment and grinding process simple and quick, improving operating efficiency; by precisely controlling the position and pressure of the grinding roller 222, the surface grinding quality of the mechanical parts can be improved; and the motor-driven adjustment system is more energy-efficient and effective than hydraulic or pneumatic systems.

[0050] In this solution, for better precision grinding of mechanical parts, please refer to... Figure 5 , Figure 10 and Figure 11 The top of the fine grinding box 21 is equipped with a liquid storage tank 25 for storing polishing liquid. The bottom of the liquid storage tank 25 is connected to a liquid outlet pipe 26 that extends into the interior of the fine grinding box 21. A solenoid valve is installed on the liquid outlet pipe 26 to form a liquid delivery channel. The solenoid valve is used to control the flow of polishing liquid. A spray head 27 is installed at the bottom of the liquid outlet pipe 26 to spray the liquid evenly onto the fine grinding roller 222 and mechanical parts. The use of polishing liquid can reduce the heat generated during the fine grinding process and improve the processing quality. The bottom of the fine grinding box 21 has a liquid outlet 28, and a waste liquid collection tank 29 is installed below the liquid outlet 28. The used liquid is discharged through the liquid outlet 28 and collected by the waste liquid collection tank 29 below. The design of the waste liquid collection tank 29 facilitates the collection and replacement of waste liquid and simplifies the maintenance of the equipment.
