Description
Technical Field
[0001] This utility model belongs to the field of parts processing technology, specifically relating to a polishing device for processing precision metal parts. Background Technology
[0002] Previously, most machinery consisted of wooden structures handcrafted by carpenters. Metal was only used to manufacture instruments, clocks, locks, pumps, and small parts for wooden machinery. With the widespread use of steam engines and the subsequent development of large machinery such as mines, metallurgy, ships, and locomotives, the demand for shaped and machined metal parts increased. The metal materials used evolved from copper and iron to steel. Machining (including casting, forging, welding, heat treatment, and related technologies and equipment, as well as cutting techniques, machine tools, cutting tools, and measuring instruments) developed rapidly, thus ensuring the supply of various mechanical equipment needed for production development.
[0003] A precision mechanical parts processing and polishing device with patent publication number CN214025115U in the prior art includes a polishing box, a support leg fixedly connected to the bottom of the polishing box, a protective cover movably connected to the top of the polishing box, a rotating handle fixedly connected to the right end of a clamping mechanism located on the right side of the polishing box, a polishing machine movably connected inside the slide groove, a polishing disc fixedly connected to the bottom of the polishing machine, a push handle fixedly connected to the outer wall of the right side of the polishing machine, a filter screen and an air pump fixedly connected inside the polishing box, and an air inlet pipe and an air outlet pipe fixedly connected to the outer wall of the air pump.
[0004] However, when this device is used to process and polish precision metal parts, if multiple locations on the outer surface of the precision metal parts need to be polished, the workers need to remove the parts and re-fix them, which is very tedious and repetitive. Therefore, a polishing device for processing precision metal parts is needed to solve the problems existing in the prior art. Utility Model Content
[0005] The purpose of this invention is to provide a polishing device for machining precision metal parts, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for machining precision metal parts, comprising a device base plate, supporting side plates fixedly connected to the left and right sides of the top of the device base plate, a connecting top plate fixedly connected to the top of the two supporting side plates, three polishing tables arranged in a rectangular array fixedly connected to the top of the device base plate, two moving grooves respectively opened on the top of the three polishing tables, a drive motor fixedly connected to the outer side of the outer surface of each of the three polishing tables, and a lead screw fixedly connected to the output end of each of the three drive motors.
[0007] In a preferred embodiment, the lead screw passes through the side wall directly outside the polishing table and rotates inside the two moving slots. The front and rear sides of the outer surface of the lead screw are respectively provided with a forward thread groove and a reverse thread groove, which are respectively located inside the two moving slots.
[0008] In a preferred embodiment, the front and rear sides of the outer surface of the lead screw are respectively threaded with movable columns, and the two movable columns move back and forth inside the two movable slots respectively. A rotating motor is fixedly connected to the top of the outer side of the outer surface of the movable column directly in front.
[0009] In a preferred embodiment, the output end of the rotary motor is fixedly connected to a drive shaft, which is rotatably connected to the top of the moving column directly in front, and a driven shaft is rotatably connected to the inner side of the top of the moving column directly behind. The inner tops of the drive shaft and the driven shaft are respectively fixedly connected to a fixing frame.
[0010] In a preferred embodiment, electric push rods are fixedly connected to the top ends of the two fixed frames, support rods are fixedly connected to the output ends of the two electric push rods, and pressing plates are fixedly connected to the bottom ends of the two support rods.
[0011] In a preferred embodiment, the output end of the rotary motor is fixedly connected to a drive shaft, which is rotatably connected to the top of the front moving column. A driven shaft is rotatably connected to the inner side of the top of the rear moving column. Fixed frames are fixedly connected to the inner tops of the drive shaft and the driven shaft, and electric push rods are fixedly connected to the tops of the two fixed frames. Support rods are fixedly connected to the output ends of the two electric push rods, and pressing plates are fixedly connected to the bottom ends of the two support rods.
[0012] In a preferred embodiment, a polishing motor is fixedly connected to the bottom end of the adjusting block, a fixed column is fixedly connected to the output end of the polishing motor, a telescopic column is slidably connected to the bottom end of the fixed column, a fixed base is fixedly connected to the bottom end of the telescopic column, and a polishing sand disc is provided at the bottom end of the fixed base.
[0013] In a preferred embodiment, the bottom end of the fixed base is provided with a threaded groove, and the top of the outer surface of the polishing sand disc is fixedly connected with a connecting thread, which is engaged with each other inside the threaded groove.
[0014] Compared with the prior art, the advantages of this utility model are:
[0015] (1) This utility model uses a moving column, a fixed frame, and a pressing plate to start the drive motor, which causes the output end of the drive motor to drive the lead screw to rotate, so that the moving columns on both sides move towards the center inside the two moving slots respectively. After moving to the appropriate position, the left and right sides of the parts to be polished are placed inside the fixed frames on both sides respectively, and the left and right sides of the parts are fixed by the fixed frames. At this time, the electric push rod is started, so that the output end of the electric push rod slides down with the support rod, which causes the support rod to slide down with the pressing plate, so that the bottom end of the pressing plate abuts against the top ends of both sides of the parts and is fixed inside the fixed frame. Thus, the parts are fixed inside the fixed frame, so that the parts will not move and cause polishing failure when the device polishes the parts, thereby improving the stability of the device and further improving the polishing efficiency of the device.
[0016] (2) This utility uses a drive shaft and a driven shaft to fix the parts firmly inside the fixed frame, and then polishes the outer surface of the parts. When other parts on the outer surface of the parts need to be polished during the polishing process, the rotating motor can be started to drive the drive shaft to rotate. Since the fixed frames on both sides fix the parts firmly, the driven shaft rotates with inertia when the drive shaft rotates. This causes the drive shaft and the driven shaft to drive the fixed frame and the fixed parts to rotate, so that the parts on the outer surface of the parts that need to be polished face upwards, which is convenient for polishing. This improves the convenience of the device and further improves its practicality. Attached Figure Description

[0024] The present invention will be further described below with reference to the embodiments.
[0025] Please see Figure 1-6 This utility model provides a polishing device for machining precision metal parts, including a device base plate 1, with supporting side plates 2 fixedly connected to the left and right sides of the top of the device base plate 1, and a connecting top plate 3 fixedly connected to the top of the two supporting side plates 2. Three polishing tables 4 arranged in a rectangular array are fixedly connected to the top of the device base plate 1. Two moving grooves 5 are opened on the top of the three polishing tables 4 respectively. A drive motor 6 is fixedly connected to the outer side of the outer surface of each of the three polishing tables 4, and a lead screw 7 is fixedly connected to the output end of each of the three drive motors 6.
[0026] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the lead screw 7 passes through the side wall directly outside the polishing table 4 and rotates inside the two moving slots 5. The front and rear sides of the outer surface of the lead screw 7 are respectively provided with a forward threaded groove 8 and a reverse threaded groove 9, which are respectively located inside the two moving slots 5.
[0027] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the front and rear sides of the outer surface of the lead screw 7 are respectively threaded with moving columns 10. The two moving columns 10 are respectively located inside the two moving slots 5 and move back and forth. The top of the outer side of the outer surface of the moving column 10 at the front is fixedly connected to a rotating motor 11.
[0028] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the output end of the rotating motor 11 is fixedly connected to the drive shaft 12, which is rotatably connected to the top of the front moving column 10. The inner side of the top of the rear moving column 10 is rotatably connected to the driven shaft 13, and the inner top of the drive shaft 12 and the driven shaft 13 are respectively fixedly connected to the fixed frame 14.
[0029] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that electric push rods 15 are fixedly connected to the top of the two fixed frames 14, and support rods 16 are fixedly connected to the output ends of the two electric push rods 15. Pressing plates 17 are fixedly connected to the bottom ends of the two support rods 16. This utility model uses the moving columns 10, fixed frames 14, and pressing plates 17 to start the drive motor 6, causing the output end of the drive motor 6 to drive the lead screw 7 to rotate. This causes the moving columns 10 on both sides to move towards the center inside the two moving slots 5, so that after moving to the appropriate position, the parts to be polished are placed on the left and right sides of the fixed frames 14 on both sides. The component is fixed inside the frame 14, thus securing the left and right sides of the component. Then, the electric push rod 15 is activated, causing its output end to slide downwards along with the support rod 16. This causes the support rod 16 to slide downwards along with the pressing plate 17, resulting in the bottom end of the pressing plate 17 contacting the tops of both sides of the component and fixing it vertically and vertically inside the frame 14. This secures the component within the frame 14, preventing it from moving and causing polishing failure during the polishing process. This improves the stability of the device and further enhances its polishing efficiency.
[0030] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that two sliding grooves 18 are provided at the bottom of the connecting top plate 3. An adjusting motor 19 is fixedly connected to the outer side of the top of the left support side plate 2. A threaded rod 20 is fixedly connected to the output end of the adjusting motor 19. The threaded rod 20 passes through the left support side plate 2 and is rotatably connected to the inner side of the top of the right support side plate 2. An adjusting block 21 is threadedly connected to the outer surface of the threaded rod 20. Two limiting sliders 22 are fixedly connected to the top of the adjusting block 21. The two limiting sliders 22 slide left and right inside the two sliding grooves 18 respectively.
[0031] Further as Figure 1 , Figure 2 and Figure 6As shown, it is worth noting that the bottom end of the adjusting block 21 is fixedly connected to a polishing motor 23, the output end of the polishing motor 23 is fixedly connected to a fixed column 24, the bottom end of the fixed column 24 is slidably connected to a telescopic column 25, the bottom end of the telescopic column 25 is fixedly connected to a fixed base 26, and the bottom end of the fixed base 26 is provided with a polishing sand disc 28.
[0032] Further as Figure 1 , Figure 2 and Figure 6 As shown, it is worth noting that the bottom of the fixed base 26 has a threaded groove 27, and the top of the outer surface of the polishing sand disc 28 is fixedly connected with a connecting thread 29. The connecting thread 29 is engaged with each other inside the threaded groove 27. This utility model uses the drive shaft 12 and the driven shaft 13 to firmly fix the parts inside the fixed frame 14, thereby polishing the outer surface of the parts. When other parts on the outer surface of the parts need to be polished during the polishing process, the rotating motor 11 can be started to drive the drive shaft 12 to rotate. When the drive shaft 12 rotates, the driven shaft 13 rotates with inertia. This causes the drive shaft 12 and the driven shaft 13 to rotate, thereby causing the fixed frame 14 and the fixed parts to rotate. This makes the parts on the outer surface of the parts that need to be polished face upwards, which is convenient for polishing. This improves the convenience of the device and further enhances its practicality.
[0033] This solution has the following working process: First, the drive motor 6 is started, causing its output end to drive the lead screw 7 to rotate. This causes the moving columns 10 on both sides to move towards the center within the two moving slots 5. After moving to the appropriate position, the left and right sides of the part to be polished are placed inside the two fixed frames 14 on both sides, thus fixing the left and right sides of the part in place by the fixed frames 14. At this time, the electric push rod 15 is started, causing its output end to slide downward with the support rod 16. This causes the support rod 16 to slide downward with the pressing plate 17, so that the bottom end of the pressing plate 17 abuts against the top ends of both sides of the part and is fixed vertically and horizontally inside the fixed frames 14. This fixes the part vertically, horizontally, and horizontally inside the fixed frames 14. According to the polishing requirements, the polishing sand disc 28 of appropriate size is connected and fixed to the fixed base 26. At this time, start the adjusting motor 19 so that its output end drives the threaded rod 20 to rotate, so that the threaded rod 20 drives the adjusting block 21 to move left and right, so that the adjusting block 21 drives the polishing sand disc 28 at the bottom to move to the appropriate polishing position. Stop the adjusting motor 19 and start the polishing motor 23 so that the output end of the moving polishing motor 23 drives the polishing sand disc 28 to rotate. With the help of the telescopic column 25, the polishing sand disc 28 polishes the parts. When other parts on the outer surface of the parts need to be polished during the polishing process, the rotating motor 11 can be started so that its output end drives the drive shaft 12 to rotate. When the drive shaft 12 rotates, the driven shaft 13 rotates with inertia. Thus, the drive shaft 12 and the driven shaft 13 drive the fixed frame 14 and the fixed parts to rotate, so that the parts on the outer surface of the parts that need to be polished face upwards.
[0034] According to the above working process, this utility model uses the moving column 10, fixed frame 14, and pressing plate 17 to start the drive motor 6, causing the output end of the drive motor 6 to drive the lead screw 7 to rotate. This causes the moving columns 10 on both sides to move towards the center inside the two moving slots 5, respectively. After moving to the appropriate position, the left and right sides of the part to be polished are placed inside the fixed frames 14 on both sides, thus fixing the left and right sides of the part in place by the fixed frames 14. At this time, the electric push rod 15 is activated, causing the output end of the electric push rod 15 to slide downward with the support rod 16. This causes the support rod 16 to slide downward with the pressing plate 17, so that the bottom end of the pressing plate 17 abuts against the top ends of both sides of the part and is fixed vertically and horizontally inside the fixed frame 14. This fixes the part vertically, horizontally, and horizontally inside the fixed frame 14, allowing the device to polish the part. During polishing, the components will not move, thus preventing polishing failure and improving the stability of the device. This further enhances the polishing efficiency. The device uses a drive shaft 12 and a driven shaft 13 to securely fix the components within the fixed frame 14, allowing for polishing of the component's outer surface. If other areas on the component's outer surface need polishing during the process, the rotating motor 11 can be started, causing its output to drive the drive shaft 12. As the drive shaft 12 rotates, the driven shaft 13 follows suit due to inertia. This causes the drive shaft 12 and driven shaft 13 to rotate, rotating the fixed frame 14 and the fixed components. This ensures that the areas on the component's outer surface requiring polishing face upwards, facilitating polishing and improving the device's convenience and practicality.
