Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to a polishing device for manufacturing agricultural and forestry machinery parts. Background Technology

[0002] Polishing refers to a processing method that uses mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the workpiece surface. Polishing does not improve the dimensional or geometric accuracy of the workpiece; rather, it aims to achieve a smooth surface or mirror-like gloss. Sometimes it is also used to eliminate gloss (matte finish). Polishing wheels are typically used as polishing tools. Publication number CN212444680U discloses a polishing device based on the production of mechanical parts, relating to the field of mechanical parts manufacturing technology. It includes a frame device for supporting polishing and a power device for the polishing operation. The frame device is equipped with a fixing device. The polishing device based on the production of mechanical parts uses a multi-station rotating setting of the fixing device to facilitate the changing of mechanical parts while polishing, saving time and improving the efficiency of polishing operations. The sliding connection of the power device makes it easy to adjust the height of the polishing disc according to the mechanical parts. The setting of the fixing device avoids manual holding for polishing, increasing safety. Although the above device improves processing efficiency by setting a rotating processing station, if the polishing precision or material is different when a polishing mechanism processes multiple workpieces, it is necessary to manually change the polishing wheel, which wastes a lot of time and reduces processing efficiency. Improvements are needed. Utility Model Content

[0004] This utility model adopts the following technical solution: a polishing device for manufacturing agricultural and forestry machinery parts, including a base, a polishing mechanism, and a clamping mechanism. The polishing mechanism includes a movable base, a rotating cylinder rotatably connected inside the movable base, a gear cover fixedly connected to the upper surface of the rotating cylinder, a motor B fixedly connected to the surface of the gear cover, a gear A fixedly connected to the output end of the motor B, a gear B rotatably connected to the surface of the rotating cylinder, a rotating shaft fixedly connected inside the gear B, a polishing wheel fixedly connected to the surface of the rotating shaft, a gear C fixedly connected to the lower surface of the rotating cylinder, a support plate B fixedly connected to the surface of the movable base, a motor C fixedly connected to the surface of the support plate B, and a gear D fixedly connected to the output end of the motor C.

[0005] Preferably, a support plate A is fixedly connected to the surface of the base, a motor A is fixedly connected to the surface of the support plate A, a screw A is fixedly connected to the output end of the motor A, and a slide rod is fixedly connected inside the base. Here, the motor A drives the screw A to rotate, and using the principle of threaded transmission, the moving seat makes linear reciprocating motion along the slide rod, realizing the horizontal position adjustment of the polishing mechanism. The slide rod provides stable guidance for the moving seat, avoiding deviation during movement and ensuring the accuracy of the polishing position.

[0006] Preferably, the interior of the movable seat is threadedly connected to the surface of the screw A, and the interior of the movable seat is slidably connected to the surface of the slide rod. Here, the interior of the movable seat has a threaded hole that matches the screw A, and the side of the movable seat has a through hole that matches the diameter of the slide rod. The combination of threaded and sliding connections allows the movable seat to move smoothly and accurately along the slide rod under the drive of the screw A.

[0007] Preferably, gear A and gear B mesh with each other, the surface of the rotating shaft is rotatably connected to the interior of the rotating cylinder, and gear C and gear D mesh with each other. Here, there are a total of six gears, including gear B, rotating shaft, and polishing wheels, evenly distributed around gear A. Driven by motor B, all six polishing wheels can rotate simultaneously. The polishing wheels are divided into three specifications and symmetrically distributed to meet the requirements of different materials and polishing precision.

[0008] Preferably, the clamping mechanism includes a fixed block, a cylinder fixedly connected to the surface of the fixed block, a clamping platform fixedly connected to the output end of the cylinder, a motor D fixedly connected to the surface of the clamping platform, a screw B fixedly connected to the output end of the motor D, and a clamping plate threadedly connected to the surface of the screw B. Here, the cylinder can quickly push the clamping platform closer to or further away from the polishing mechanism, facilitating convenient clamping and unloading of parts. The motor D drives the screw B to rotate, causing the clamping plate to slide along the clamping platform via threaded transmission. The clamping distance can be adjusted according to the size of the parts, achieving stable clamping of agricultural and forestry machinery parts of different specifications.

[0009] Preferably, the lower surface of the fixing block is fixedly connected to the surface of the base, the surface of the screw B is rotatably connected to the interior of the clamping platform, and the surface of the clamping plate is slidably connected to the interior of the clamping platform. Here, the rotatable connection between the screw B and the interior of the clamping platform ensures that the screw B remains stable during rotation, and the clamping platform further improves the stability of the clamping plate's movement. This robust fixing method ensures that the clamping mechanism remains stable during operation and will not displace due to polishing force.

The polishing mechanism 5 includes a movable base 51, a rotating cylinder 52 rotatably connected inside the movable base 51, and a gear cover 53 fixedly connected to the upper surface of the rotating cylinder 52. Here, the gear cover 53 can provide protection. A motor B54 is fixedly connected to the surface of the gear cover 53, and a gear A55 is fixedly connected to the output end of the motor B54. Gears B56 are rotatably connected to the surface of the rotating cylinder 52. Here, there are six gears B56, which are evenly distributed around the gear A55 and mesh with it. An internal rotating shaft 57 is fixedly connected, and a polishing wheel 58 is fixedly connected to the surface of the rotating shaft 57. Here, the polishing wheel 58 is made of three different materials to meet the polishing requirements of mechanical parts made of different materials. A gear C59 is fixedly connected to the lower surface of the rotating cylinder 52. A support plate B510 is fixedly connected to the surface of the movable seat 51, and a motor C511 is fixedly connected to the surface of the support plate B510. A gear D512 is fixedly connected to the output end of the motor C511. A support plate A2 is fixedly connected to the surface of the base 1, and a motor A3 is fixedly connected to the surface of the support plate A2. A screw A4 is fixedly connected to the output end of the motor A3. A sliding rod 7 is fixedly connected internally to the base 1. Here, the motor A3 drives the screw A4 to rotate, and using the principle of threaded transmission, the movable seat 51 makes linear reciprocating motion along the sliding rod 7, realizing the horizontal position adjustment of the polishing mechanism 5. The slide bar 7 provides stable guidance for the movable seat 51, preventing deviation during movement and ensuring the accuracy of the polishing position. The interior of the movable seat 51 is threadedly connected to the surface of the screw A4, and the interior of the movable seat 51 is slidably connected to the surface of the slide bar 7. Here, the bottom of the movable seat 51 has a threaded hole that matches the screw A4, and the side of the movable seat 51 has a through hole that matches the diameter of the slide bar 7. The combination of threaded and sliding connections allows the movable seat 51 to move smoothly and accurately along the slide bar 7 under the drive of the screw A4. The movable seat 51 is a T-shaped block that matches the slot in the base 1. Gear A55 and gear B56 mesh with each other, the surface of the rotating shaft 57 is rotatably connected to the interior of the rotating cylinder 52, and gear C59 and gear D512 mesh with each other. Here, there are a total of six gears B56, rotating shaft 57, and polishing wheels 58, which are evenly distributed around gear A55.

[0024] Example 2

[0025] Please see Figure 1 , Figure 5The clamping mechanism 6 includes a fixed block 61, a cylinder 62 fixedly connected to the surface of the fixed block 61, a clamping platform 63 fixedly connected to the output end of the cylinder 62, a motor D64 fixedly connected to the surface of the clamping platform 63, a screw B65 fixedly connected to the output end of the motor D64, and a clamping plate 66 threadedly connected to the surface of the screw B65. Here, the cylinder 62 can quickly push the clamping platform 63 closer to or further away from the polishing mechanism 5, enabling convenient clamping and unloading of parts. The motor D64 drives the screw B65 to rotate, causing the clamping plate 66 to slide along the clamping platform 63 via threaded transmission. The clamping distance can be adjusted according to the size of the parts, achieving stable clamping of agricultural and forestry machinery parts of different specifications. The bidirectional thread design allows the clamping plates 66 to clamp synchronously, ensuring the symmetry and stability of the parts clamping and preventing the parts from shaking during polishing, which would affect the polishing effect. The lower surface of the fixing block 61 is fixedly connected to the surface of the base 1, the surface of the screw B65 is rotatably connected to the interior of the clamping table 63, and the surface of the clamping plate 66 is slidably connected to the interior of the clamping table 63. Here, the rotatable connection between the screw B65 and the interior of the clamping table 63 ensures that the screw B65 remains stable during rotation, and the clamping table 63 further improves the stability of the movement of the clamping plate 66. The firm fixing method keeps the clamping mechanism 6 stable during operation and will not be displaced by the polishing force. At the same time, the two clamping mechanisms 6 are symmetrically arranged on both sides of the polishing mechanism 5, which can perform multiple workpiece polishing tasks simultaneously, further improving the working efficiency of the equipment.

[0026] Working principle: First, the agricultural and forestry machinery parts to be polished are placed on the clamping table 63. The motor D64 is started, and its drive screw B65 rotates. Utilizing the thread transmission principle, the clamping plate 66 slides along the clamping table 63. The clamping distance is adjusted according to the size of the parts. The bidirectional thread design ensures that the clamping plates 66 clamp synchronously, guaranteeing the symmetry and stability of the parts clamping. Subsequently, the cylinder 62 is activated, and its output end pushes the clamping table 63 to move, adjusting the workpiece to the appropriate polishing position. If different polishing wheels 58 of different fineness are required, start motor C511. The output gear D512 drives the meshing gear C59 to rotate, thus rotating the drum 52. Adjust the position of the polishing wheel 58. After selecting the polishing wheel 58, start motor B54. The output gear A55 drives multiple meshing gears B56 to rotate, thereby driving multiple rotating shafts 57 and the polishing wheel 58 fixedly connected to the surface to rotate synchronously for polishing. Simultaneously, start motor A3, which drives screw A4 to rotate. Under the threaded transmission of screw A4 and the guidance of slide rod 7, the moving seat 51 makes a linear reciprocating motion in the horizontal direction, allowing the polishing wheel 58 to polish the workpiece on the clamping mechanism 6. Because two clamping mechanisms 6 are symmetrically arranged on both sides of the polishing mechanism 5, multiple workpieces can be polished simultaneously, further improving the equipment's working efficiency.
