Description

Technical Field

[0001] This utility model relates to the field of metal parts manufacturing technology, specifically a polishing device for metal parts manufacturing. Background Technology

[0002] As we all know, there are many types of metal fittings, which can be divided into several categories according to their use, such as construction, furniture, automobiles, and electronic appliances. These include door and window hinges, furniture handles, automobile engine parts, and electronic equipment radiators. They play an important role in connecting, fixing, and ensuring performance in various fields. During the production of metal fittings, polishing equipment is needed to grind and polish the workpieces.

[0003] In the existing polishing equipment, changing workpieces requires the polishing wheel to stop completely and be raised. The workpiece on the processing table can only be changed when the equipment is completely stopped. The whole process involves stopping, changing parts, and restarting. The frequent start-stop operations not only prolong the processing cycle of a single workpiece, but also cause energy waste and mechanical wear due to repeated equipment starts, affecting production continuity and processing efficiency.

[0028] First, refer to Figure 1 and Figure 7 In this embodiment, two sets of first electric push rods 9 are provided on the outer side of the fixed platform 4. The output end of the first electric push rod 9 extends into the fixed platform 4 and is keyed to the clamping block 11. After the workpiece is placed in the fixed platform 4, the first electric push rod 9 is turned on so that its output end drives the clamping block 11 to move and clamp the workpiece. Two sets of springs 8 are provided on the outer side of the fixed platform 4. The end of the spring 8 away from the fixed platform 4 is provided with a mounting platform 7. The mounting platform 7 is fixedly set on the outer side of the machine body 1. Thus, when the fixed platform 4 is pushed, the spring 8 will be squeezed by the fixed platform 4. When the fixed platform 4 is no longer pushed, the spring 8 will bounce the fixed platform 4 back, thereby causing the fixed platform 4 to move the workpiece to the bottom of the grinding disc 14. Two sets of buffer pads 10 are provided on the top of the machine body 1. The buffer pads 10 are rubber buffer pads. When the fixed platform 4 contacts the buffer pads 10, it will be blocked and unable to move. At this time, the workpiece in the fixed platform 4 will be located below the grinding disc 14.

[0029] Then, refer to Figures 2 to 5In this embodiment, the adjusting assembly 2 includes a horizontal plate 201 disposed on the inner wall of the movable groove 6 and a balance bar 204 slidably connected within the movable groove 6. A support column 203 is welded to the top of the balance bar 204, and the top of the support column 203 is bolted to the bottom of the fixed platform 4. Two sets of parallel fixed shafts 207 are welded to the top of the horizontal plate 201. A swing plate 206 is rotatably disposed on the outer side of the fixed shafts 207. The swing plate is inclined. A connecting column 202 is rotatably disposed on the side of the swing plate 206 away from the fixed shafts 207. Both sets of connecting columns 202 are slidably connected to the outer side of the balance bar 204. One side of the horizontal plate 201 is welded with There are two sets of fixed plates 209. The fixed plates 209 are rotatably connected to a movable shaft 208. Two sets of discs are provided on the outside of the movable shaft 208, and the two sets of discs are located on both sides of the fixed plates 209. The discs can prevent the movable shaft 208 from detaching from the fixed plates 209. A movable plate 211 is welded to the top of the movable shaft 208. The movable plate 211 is inclined. A gear 210 is provided on the outside of the movable shaft 208. A central shaft 212 is welded to the side of the movable plate 211 away from the movable shaft 208. A pulley 213 is rotatably connected to the outside of the central shaft 212. The pulley 213 and the swing plate 206 are in contact on the side away from the movable shaft 208.

[0030] Secondly, see Figure 4 In this embodiment, both ends of the balance bar 204 are welded with baffle plates 205. The baffle plates 205 can block the connecting column 202 and prevent the connecting column 202 from detaching from the balance bar 204.

[0031] When gear 210 is pushed, it will drive the movable shaft 208 to rotate. The rotation of the movable shaft 208 will drive the movable plate 211 to rotate around the movable shaft 208. When the movable plate 211 is moving, it will drive the pulley 213 to move by driving the central shaft 212 and push the swing plate 206. When the swing plate 206 is pushed, it will swing around the fixed shaft 207. At this time, the side of the swing plate 206 away from the fixed shaft 207 will push the connecting column 202 to move outside the balance bar 204. At the same time, the movement of the connecting column 202 will push the balance bar 204 to move laterally. The lateral movement of the balance bar 204 will drive the fixed table 4 to move laterally by driving the support column 203, thereby causing the fixed table 4 to lift the workpiece inside it out of the grinding disc 14, which facilitates the operator to change the workpiece.

[0032] Finally, see Figure 2 , Figure 3 and Figure 6In this embodiment, the drive assembly 3 includes a rotary motor 301 disposed on the inner wall of the movable groove 6 and a rotating column 304 rotatably connected within the movable groove 6. The rotary motor 301 is a bidirectional motor, and its output end can rotate forward or backward. The two ends of the rotating column 304 are respectively provided with a first threaded tube 302 and a second threaded tube 306. The threads on the outer sides of the first threaded tube 302 and the second threaded tube 306 are in opposite directions. The end of the first threaded tube 302 away from the rotating column 304 is keyed to the output end of the rotary motor 301. The outer sides of both the first threaded tube 302 and the second threaded tube 306 are screwed together. There is a sleeve 303, and two sets of racks 305 are provided on the outside of the sleeve 303. The racks 305 mesh with the gear 210. After the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the first threaded tube 302 to rotate. The rotation of the first threaded tube 302 will drive the second threaded tube 306 to rotate by driving the rotating column 304. The rotation of the first threaded tube 302 and the second threaded tube 306 will drive the two sets of sleeves 303 to linear displacement. The movement of the sleeves 303 will drive the racks 305 to move. When the racks 305 move, they will push the gear 210 to rotate.

[0033] This polishing device for producing metal parts, through the cooperation between pulley 213 and swing plate 206, when pulley 213 moves and pushes the swing plate 206, the swing plate 206 will push the balance bar 204 to move during the swing. The movement of the balance bar 204 will change the position of the fixed table 4, so that the workpiece on the fixed table 4 can be removed from the polishing structure without stopping the machine, avoiding the situation of stopping the machine to change parts, and ensuring the processing efficiency of metal parts.

[0034] Working principle:

[0035] When using this polishing device for metal parts production, first place the device in the desired position, then install the metal workpiece. The specific operation is as follows: turn on the rotary motor 301 so that its output end drives the first threaded tube 302 to rotate. The rotation of the first threaded tube 302 will drive the second threaded tube 306 to rotate by driving the rotating column 304. The rotation of the first threaded tube 302 and the second threaded tube 306 will drive the two sets of sleeves 303 to move linearly. The movement of the sleeves 303 will drive the rack 305 to move. When the rack 305 moves, it will push the gear 210 to rotate.

[0036] When gear 210 is pushed, it will drive the movable shaft 208 to rotate. The rotation of the movable shaft 208 will drive the movable plate 211 to rotate around the movable shaft 208. When the movable plate 211 is moving, it will drive the pulley 213 to move by driving the central shaft 212 and push the swing plate 206. When the swing plate 206 is pushed, it will swing around the fixed shaft 207. At this time, the side of the swing plate 206 away from the fixed shaft 207 will push the connecting column 202 to move outside the balance bar 204. At the same time, the movement of the connecting column 202 will push the balance bar 204 to move laterally. The lateral movement of the balance bar 204 will drive the fixed table 4 to move laterally by driving the support column 203, so that the fixed table 4 is separated from the grinding disc 14. Then the workpiece is placed in the fixed table 4 and the first electric push rod 9 is turned on so that its output end drives the clamping block 11 to move and clamp the workpiece.

[0037] Then, the output end of the rotating motor 301 is reversed, causing the rack 305 to move back and push the gear 210 to rotate. At this time, the pulley 213 will no longer push the swing plate 206. Then the spring 8 will bounce the fixed table 4 back, so that the fixed table 4 will drive the workpiece back to the bottom of the grinding disc 14. Then, the second electric push rod 12 is turned on, so that its output end drives the grinding motor 13 and the grinding disc 14 to move down by driving the placement block to move down, so that the grinding disc 14 contacts the workpiece. After the grinding motor 13 is turned on, the output end of the grinding motor 13 will drive the grinding disc 14 to rotate and polish the workpiece, thus completing the grinding work of the workpiece.
