Description

Technical Field

[0001] This invention relates to the field of polishing machine technology, and in particular to a polishing device for the surface of tin-phosphor bronze plates. Background Technology

[0002] Bronze is one of the earliest alloys used by mankind. It is corrosion-resistant and has good mechanical and technological properties, making it widely used in steam boilers and ship parts. During the processing and polishing of bronze plates, the carved parts need to be polished in detail. However, the current fine polishing process may require changing the angle or the polishing head, which not only delays the processing progress, but also the polishing machines available on the market have a simple structure and cannot meet the requirements of multi-angle polishing.

[0003] Patent publication number CN209579103U discloses a small grinder with easy-to-change grinding needles, a drive mechanism, and grinding needles. The drive mechanism includes a motor cylinder, a motor, a power cord, and a rear cover. The motor is installed inside the motor cylinder, and the power cord is connected to the rear end of the motor. The rear cover is installed at the rear end of the motor cylinder. A half-iron is threaded to the front end of the motor cylinder. A fourth spring and a lifting sleeve are installed inside the half-iron in sequence. A rotating sleeve is sleeved on the outside of the half-iron. A front nozzle is threaded to the end of the half-iron away from the drive mechanism. An outer collar is installed on the front nozzle. A coupling is installed at the other end of the front nozzle. An adjusting screw is connected to the front nozzle through the coupling. A third spring is sleeved on the end of the adjusting screw near the coupling.

[0004] By configuring the grinding needle, clamping shaft, hollow shaft, lifting sleeve, and motor, when the grinding needle needs to be replaced, the rotation... The rotating sleeve and lifting sleeve lift the adjusting screw, thereby pushing the clamping shaft to loosen the grinding needle, remove the old grinding needle, insert the new grinding needle into the three-lobed chuck of the clamping shaft, and then rotate the rotating sleeve in the opposite direction. The lifting sleeve retracts, loosens the adjusting screw, and the second spring regains its elasticity, tightening the clamping shaft again and re-clamping the grinding needle. This existing technology has very limited functionality and requires frequent changes of grinding heads to achieve various grinding effects. Frequent grinding head changes are time-consuming and labor-intensive. Therefore, a grinding and processing device for the surface of tin-phosphor bronze plates is being developed. Summary of the Invention

[0005] This invention provides a surface grinding and processing device for tin phosphor bronze plates that does not require frequent replacement of grinding heads, thereby overcoming the shortcomings of existing small grinding machines that have limited functionality and require frequent replacement of grinding heads, which is time-consuming and labor-intensive.

The guide components have two ends that are rotatably connected to the guide ring.

[0007] Furthermore, it also includes a gear ring, which is fixedly connected to the drive shaft of the grinder, and the gear ring meshes with the gear.

[0008] Furthermore, it also includes a clamping frame, the bottom of which is rotatably connected to the surface of the worktable, and the two ends of the clamping frame that extend outward have grooves respectively; The clamping components are slidably connected to the inside of the two grooves of the clamping frame; A storage spring is connected between the clamping part and the groove.

[0009] Furthermore, it also includes a grinding rod, which is fixedly connected to the front end of the rotating component; Guide ring, the guide ring is slidably connected to the grinding rod; The retaining ring is fixedly connected to the grinding rod; The second telescopic rod, several of which are fixedly connected to the fixed ring; The second grinding block is connected to the end of the second telescopic rod. Connectors are all connected to the second grinding block; The connecting plates are rotatably connected between the guide ring and the connector. The first grinding block is connected to the connecting plate.

[0010] Furthermore, it also includes a connecting rod, the front end of which extends into the interior of the grinding rod until it reaches the position of the guide ring and extends upward to be fixedly connected to the guide ring; The kala component is slidably connected to the rotating component, and the tail of the kala component extends into the interior of the rotating component and is fixedly connected to the tail of the connecting rod.

[0011] Furthermore, it also includes fixing brackets, with two fixing brackets respectively connected to the rotating component; The barrier components are slidably connected to the ends of the fixed frame, and the sides of the two barrier components that are close to each other have an inclined surface. Compression springs are connected between the fixing bracket and the blocking component.

[0012] Furthermore, it also includes a pressing sleeve, which is connected to the tail of the grinder, with the front inner wall of the pressing sleeve suspended above the outer wall of the grinder.

[0013] Furthermore, it also includes a second sliding frame, which is fixedly connected to the pressing member; The lower pressing component and the pressing plate are provided. The tail of the lower pressing component is fixedly connected to the pressing plate inside the pressing sleeve, and the front end of the lower pressing component is slidably connected to the second sliding frame. The lower pressing component is provided with a protruding rod. The pressure springs are connected between the lower pressing member and the pressing member; The toothed brackets are fixedly connected to the rotating ring.

[0014] Furthermore, it also includes a fixing ring, which is fixedly connected to the bracket extending outward from the rotating ring, and the surface of the fixing ring is provided with several holes; The lower pressure frame and the extrusion block are connected by sliding the tail of the lower pressure frame through the tail of the toothed frame. The extrusion block is squeezed into the hole on the fixed ring. The ends of the lower pressure frame pass through the teeth on the toothed frame. Linear springs are connected between the toothed frame and the compression block.

[0015] The present invention has the following advantages: 1. The present invention adjusts the grinding angle of the grinding part by pushing the pressing part. Because the pressing part is fixedly connected to the first sliding frame, the front end of the first sliding frame is connected to the connecting ring, the connecting ring is connected to the gear, and the first sliding frame is slidably connected to the rotating ring, so pushing the pressing part back and forth can make the telescopic part extend and retract, and the grinding part can change its angle under the action of the telescopic part, thereby realizing the change of the grinding angle of the grinding part.

[0016] 2. In this invention, the karaoke piece is moved to the rear of the blocking piece. As the karaoke piece moves backward, the connecting rod moves backward as well. The guide ring is slidably connected to the grinding rod. Therefore, when the guide ring moves backward, the connecting plate will cause the second telescopic rod to extend outward. As the second telescopic rod extends outward, it will also cause the second grinding block to extend outward together. Finally, it will form a circular grinding head of different sizes, so as to perform fine grinding on different parts of the carving.

[0017] 3. In this invention, the user holds a pressing sleeve, and by pressing the pressing plate, the pressing plate moves the lower pressing component. The movement of the lower pressing component first compresses the pressure spring, and then the lower pressing component compresses the lower pressing frame, causing the lower pressing frame to move. The lower pressing frame then moves the pressing block, which in turn stretches the linear spring, finally causing the pressing block to engage with the hole on the fixing ring. By locking the fixing ring with the lower pressing frame, the rotation of the fixing ring is prevented, thus preventing the rotating ring from rotating and achieving a locking effect on the rotating ring. The lower pressing component engages with the tooth groove of the toothed frame, thereby preventing the first sliding frame from moving back and forth. This locks the position of the first sliding frame, thus preventing accidental changes in the angle of the grinding part. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention. Example 1

[0031] A grinding and polishing device for tin-phosphor bronze plates, see [link / reference] Figures 1 to 3It includes a worktable 1, a clamping frame 11, a storage spring 12, a clamping component 13, a support frame 14, a grinder 15, a rotating component 16, a rotating frame 17, a first sliding frame 18, a pressing component 19, a gear 110, a connecting ring 111, a universal joint 112, a telescopic component 113, a grinding component 114, a guide component 115, a gear ring 116, a rotating ring 117, and a guide ring 119. The bottom of the clamping frame 11 is rotatably connected to the surface of the worktable 1. The clamping frame 11 is oriented towards... The two protruding ends each have grooves. Two clamping parts 13 are slidably connected to the inside of the two grooves of the clamping frame 11. A storage spring 12 is connected between the clamping parts 13 and the grooves. Two support frames 14 are fixedly connected to the right edge of the worktable 1. The grinder 15 is placed on the support frame 14. The front end of the grinder 15 is provided with a drive shaft. A rotating part 16 is fixedly connected to the drive shaft of the grinder 15. A rotating frame 17 is fixedly connected to the front end of the grinder 15. The rotating frame 17 has four outwardly extending brackets. The rotating ring 117 is rotatably connected to the outwardly extending brackets of the rotating frame 17. Two first sliding frames 18 are slidably connected to the top and bottom of the rotating ring 117, respectively. Pressing parts 19 are fixedly connected to the first sliding frames 18, and connecting rings 111 are rotatably connected to the front end of the first sliding frames 18, respectively. The tail of the gear 110 is fixedly connected to the connecting ring 111, respectively. Universal joints 112 are fixedly connected to the front end of the gear 110, respectively. The tail of the telescopic part 113 is connected to the universal joint 112, respectively. The tail of the grinding part 114 is connected to the front end of the telescopic part 113, respectively. The tail of the guide part 115 is rotatably connected to the front end of the grinding part 114, respectively. The guide ring 119 is rotatably connected to the rotating part 16, respectively. The ends of the two guide parts 115 are rotatably connected to the guide ring 119, respectively. The gear ring 116 is fixedly connected to the drive shaft of the grinder 15, and the gear ring 116 meshes with the gear 110.

[0032] During the processing and polishing of bronze plates, fine polishing of the carved parts is required. However, this fine polishing process may require changing angles or polishing heads, which delays the processing progress and necessitates constant adjustment of the polishing piece 114 to find a better polishing angle, which is very troublesome. Therefore, this application addresses the above-mentioned situation by taking the following measures: When fine polishing of a bronze plate is required, the bronze plate to be polished is first placed in the clamping frame 11. The bronze plate is fixed on the clamping frame 11. The storage spring 12 fixes the clamping part 13 to the bronze plate, preventing it from wobbling during subsequent polishing. After the bronze plate is fixed, the clamping frame 11 can be manually rotated to change the angle of the bronze plate. After the bronze plate is fixed, the polisher 15 is lifted from the support frame 14 and the switch of the polisher 15 is turned on. The motor inside the polisher 15 drives the drive shaft at the front end of the polisher 15 to rotate. The gear ring 116 is connected to the front end of the polisher 15. Driven by the drive shaft at the front end of the polisher 15, the gear ring 116 rotates. The gear ring 116 meshes with the gear 110, which in turn rotates. The gear 110 is connected to the universal joint 112, which in turn rotates the telescopic component 113. The telescopic component 113 is connected to the polishing component 114, which in turn rotates the polishing component 114. The rotation of the polishing component 114 polishes the bronze plate. The polishing component 114 needs to be adjusted according to the shape and structure of the carved parts on the bronze plate. The grinding angle is adjusted to facilitate grinding of the carved parts. The pressing part 19 can be pushed. Since the pressing part 19 is fixedly connected to the first sliding frame 18, the front end of the first sliding frame 18 is connected to the connecting ring 111, and the connecting ring 111 is connected to the gear 110. The first sliding frame 18 is slidably connected to the rotating ring 117. Therefore, pushing the pressing part 19 back and forth can extend and retract the telescopic part 113. The grinding part 114 can change its angle under the action of the telescopic part 113, thereby realizing the change of the grinding angle of the grinding part 114 to meet various needs. Example 2

[0033] Based on Example 1, see Figures 4 to 7It also includes a guide ring 2, a first grinding block 22, a second grinding block 23, a connector 24, a second telescopic rod 25, a connecting rod 26, a clasp 27, a fixing frame 28, a blocking component 29, a compression spring 210, a grinding rod 211, and a fixing ring 212. The grinding rod 211 is fixedly connected to the front end of the rotating component 16. The guide ring 2 is slidably connected to the grinding rod 211. The front end of the connecting rod 26 extends into the interior of the grinding rod 211 until it reaches the position of the guide ring 2, then extends upward and is fixedly connected to the guide ring 2. The fixing ring 212 is fixedly connected to the grinding rod 211. Several second telescopic rods 25 are fixedly connected to the fixing ring 212. The second grinding blocks 23 are respectively connected to... Connecting to the end of the second telescopic rod 25, the connecting piece 24 is connected to the second grinding block 23, the connecting plate 21 is rotatably connected between the guide ring 2 and the connecting piece 24, the first grinding block 22 is connected to the top and bottom of the connecting plate 21, the karaoke piece 27 is slidably connected to the rotating piece 16, the tail of the karaoke piece 27 extends into the interior of the rotating piece 16 and is fixedly connected to the tail of the connecting rod 26, one end of the two fixing brackets 28 is respectively connected to the rotating piece 16, the blocking piece 29 is slidably connected to the other end of the fixing bracket 28, the two blocking pieces 29 have a slope on the side that is close to each other, and a compression spring 210 is slidably connected between the fixing bracket 28 and the blocking piece 29.

[0034] When polishing the carved areas of bronze plates, fine polishing is required, and the need for polishing heads is also diverse. Different sized polishing heads are needed for bronze plate carvings with different structures, and changing them back and forth is very troublesome. Based on this, this application takes the following measures to deal with the above situation: When encountering a bronze surface where it is necessary to change the polishing head, the inclined surfaces of the carabiner 27 and the blocking member 29 can be pulled backward to make contact. This will squeeze the blocking member 29 to move in a position away from each other, and the blocking member 29 and the fixed... A compression spring 210 is connected between the frames 28. The compression spring 210 is compressed inwards due to the movement of the blocking member 29. When the karaoke piece 27 moves behind the blocking member 29, the compression spring 210 returns to its original position, causing the blocking member 29 to move closer together and lock the karaoke piece 27 in place. Therefore, the blocking member 29 acts as a barrier to the karaoke piece 27. As the karaoke piece 27 moves backward, it also causes the connecting rod 26 to move backward. The guide ring 2 is slidably connected to the grinding rod because of the fixed connection 212. On the grinding rod 211, several second telescopic rods 25 are fixedly connected to the fixing ring 212. The bottom of the second grinding block 23 is connected to the end of the second telescopic rod 25. The connecting piece 24 is connected to the second grinding block 23. The connecting plate 21 is rotatably connected between the guide ring 2 and the connecting piece 24. The first grinding block 22 is connected to the connecting plate 21. When the guide ring 2 moves backward, it drives the connecting plate 21 to move outward. The outward movement of the connecting plate 21 drives the second telescopic rods 25 to extend outward. As the second telescopic rods 25 extend outward, they simultaneously drive the second telescopic rods 25 to extend outward. The second polishing block 23 extends outward together, eventually forming a circular polishing head. If it is necessary to restore the original polishing head, the carabiner 27 needs to be pushed out of the obstruction of the blocking member 29 and returned to its original position. The carabiner 27 drives the connecting rod 26 to move forward, and the connecting rod 26 drives the guide ring 2 to move forward. The guide ring 2 drives the second telescopic rod 25 to retract through the connecting plate 21. By adjusting the position of the second polishing block 23, different sizes of polishing heads can be switched so as to perform fine polishing on different parts of the carving.

[0035] See Figures 8 to 11It also includes a lower pressing member 3, a fixing ring 31, a toothed frame 32, a lower pressing frame 33, a pressing block 34, a pressure spring 35, a linear spring 36, a pressing plate 37, and a pressing sleeve 38. The pressing sleeve 38 is connected to the tail of the grinder 15, and the front inner wall of the pressing sleeve is suspended above the outer wall of the grinder 15. The tail of the lower pressing member 3 is fixedly connected to the pressing plate 37 located inside the pressing sleeve 38. The pressing sleeve 38 and the pressing plate 37 are mutually pressed and engaged. The second sliding frame 39 is fixedly connected to the pressing member 19, and the front end of the lower pressing member 3 is slidably connected to the second sliding frame 39, so that the lower pressing member 3 can slide on the second sliding frame. The pressing member 39 slides on top of the pressing member 19. The pressing member 3 has a protruding rod. The pressure springs 35 are all connected between the pressing member 3 and the pressing member 19. The fixing ring 31 is fixedly connected to the bracket extending outward from the rotating frame 17. The surface of the fixing ring 31 has several holes. The two toothed frames 32 are fixedly connected to the rotating ring 117 respectively. The tail of the pressing member 33 slides through the tail of the toothed frame 32 and connects to the extrusion block 34. The extrusion block 34 is squeezed and fitted with the holes on the fixing ring 31. The ends of the pressing member 33 all pass through the teeth on the toothed frame 32. The linear springs 36 are all connected between the toothed frame 32 and the extrusion block 34.

[0036] During the polishing process using the polisher 15, the first sliding frame 18 and the rotating ring 117 are slidably connected. Since the rotating ring 117 is rotatably connected, pushing the pressing piece 19 can adjust the horizontal and oblique angles of the polishing piece 114, achieving precise polishing of the bronze plate carvings. However, when a person holds the polisher 15, their hand can easily accidentally touch the first sliding frame 18, causing it to shift. This displacement can easily alter the angle of the polishing piece 114, affecting the already adjusted angle and hindering fine polishing. Furthermore, if a person accidentally touches the rotating ring 117, it will rotate, causing the already adjusted angle of the polishing piece 114 to rotate again, which is detrimental to polishing. Therefore, this application takes the following measures to address the above situations: When the positions of the first sliding frame 18 and the rotating ring 117 are adjusted, the person holds the pressing sleeve 38... When the hands press the pressing plate 37 through the pressing sleeve 38, the pressing plate 37 moves to one side closer to each other. The movement of the pressing plate 37 to one side closer to each other will drive the lower pressing member 3 to move to one side closer to each other. The movement of the lower pressing member 3 to one side closer to each other will first compress the pressure spring 35, and then the lower pressing member 3 will compress the lower pressing frame 33. The lower pressing frame 33 will then move to one side closer to each other, and at the same time drive the pressing block 34 to move to one side closer to each other. The movement of the pressing block 34 to one side closer to each other will stretch the linear spring 36, and finally make the lower pressing frame 34 engage with the hole on the fixing ring 31. By locking the fixing ring 31 with the lower pressing frame 34, the rotation of the fixing ring 31 can be prevented, thereby preventing the rotation of the rotating ring 117 and locking the rotating ring 117. The movement of the lower pressing member 3 to one side closer to each other will engage with the tooth groove of the toothed tooth frame 32, thereby preventing the first sliding frame 18 from moving back and forth. In this way, the position of the first sliding frame 18 can be locked back and forth, thus preventing the above-mentioned problems from occurring.
