Description

Technical Field

[0001] This utility model relates to the field of edge grinding device technology, specifically to an edge grinding device for metal parts. Background Technology

[0002] Metal parts are core components in industries such as machinery manufacturing, automotive, electronic equipment, and aerospace. The quality of their edges directly affects the assembly accuracy, safety, and appearance of products. Edge processing is a crucial step in ensuring product quality, and edge grinding equipment is the core equipment for achieving this process.

[0003] Chinese Patent Announcement No. CN220279158U discloses a metal parts grinding device, including a worktable. The worktable is equipped with a transverse movement device, a lifting device, and a grinding device. The transverse movement device includes a support frame, a lead screw, a first motor, a moving seat, and a guide rail. Two support frames are provided, both of which are set on the worktable. The two ends of the lead screw are rotatably connected to the two support frames respectively. The two ends of the guide rail are fixedly connected to the support frames. The moving seat is threaded onto the lead screw and slides with the guide rail. The first motor is connected to one of the support frames, and its output end passes through the support frame and is connected to the lead screw. This utility model is equipped with a transverse movement device and a pneumatic clamp to facilitate the clamping and fixing of the workpiece, preventing relative displacement between the workpiece and the moving seat during the grinding process. The guide rail guides the moving seat, improving the accuracy of the workpiece's forward direction and preventing it from deviating.

[0004] In the prior art, during the use of a metal parts grinding device, metal shavings generated during grinding accumulate on the worktable, in the contact area between the grinding device and the workpiece, and cannot be discharged in time. The shavings are also rolled into the friction surface as the grinding mechanism operates, which accelerates the wear rate of the grinding mechanism (such as the grinding head and grinding wheel), reduces the service life of the device and the grinding accuracy. At the same time, metal shavings (especially fine dust-like shavings) are dispersed into the working environment during the grinding process, and long-term inhalation by operators can easily cause respiratory diseases and other health problems. Therefore, we have made improvements to this and proposed a metal parts grinding device. Utility Model Content

[0031] Example 1: Please refer to the appendix of the instruction manual. Figure 1 -3, a metal fitting edge grinding device, comprising a base 1, a U-shaped base 2 disposed above the base 1, the U-shaped base 2 being U-shaped, an edge grinding structure mounting groove 3 being formed on one side of the top of the base 1, a pressure plate 4 being slidably connected to the inner wall of the U-shaped base 2, a collection box 9 being fixedly installed on the bottom side of the U-shaped base 2 near the edge grinding structure mounting groove 3, and the collection box 9 being slidably connected to the base 1, a sliding plate 5 being slidably connected inside the U-shaped base 2, and the sliding plate 5 passing through the U-shaped base 2 and being slidably connected to it, two L-shaped support rods 7 being fixedly installed on one side of the sliding plate 5, a collection cylinder 6 being disposed between the two L-shaped support rods 7, and the two L-shaped support rods 7 being fixedly connected to the collection cylinder 6, and a negative pressure pump 1 being fixedly installed on the side of the collection box 9 away from the collection cylinder 6. A guide pipe 8 is fixedly installed on one side of the collection cylinder 6 and at the bottom of one of the L-shaped support rods 7. A through groove is opened on the collection cylinder 6 to cooperate with the guide pipe 8. The guide pipe 8 is inserted into the inside of the collection box 9 and slidably connected to it. Several filter plates 11 are fixedly installed inside the collection box 9. The aperture of the filter plates 11 gradually increases on the side close to the guide pipe 8. A box plate is opened on the side of the collection box 9 away from the annular cover 19. The box plate is inserted into the inside of the collection box 9 and slidably connected to it. Fixing screws are provided at the four corners of the side of the box plate away from the collection box 9. Several fixing screws pass through the box plate and are threaded to it. Several fixing screws are inserted into the inside of the collection box 9 and are threaded to it. Several auxiliary structures are provided on the collection cylinder 6.

[0032] In this embodiment of the utility model, the metal part to be ground is placed at the bottom of the inner wall of the U-shaped base 2, and the part is pressed and fixed by the sliding of the pressure plate 4 along the inner wall of the U-shaped base 2; according to the grinding position of the part, the sliding position of the slide plate 5 in the U-shaped base 2 is adjusted, which drives the L-shaped support rod 7 and the collection cylinder 6 to move, so that the opening of the collection cylinder 6 is aligned with the contact point between the grinding mechanism and the part in the grinding structure mounting groove 3, while ensuring that the guide tube 8 is stably inserted into the collection box 9.

[0033] When the negative pressure pump 10 is started, a negative pressure environment is formed inside the collection box 9, which generates suction on the collection cylinder 6 through the guide pipe 8. Metal shavings generated during the edge grinding mechanism are sucked into the collection cylinder 6 under the action of negative pressure, enter the guide pipe 8 through the through groove, and then flow into the collection box 9. After entering the collection box 9, the shavings pass through the filter plates 11 with gradually increasing pore size in sequence. Small particles of shavings are intercepted by the filter plates 11 with smaller pore size, while large particles of shavings are received by the subsequent filter plates 11 with larger pore size, realizing the stratified filtration and collection of shavings. After the edge grinding is completed, the negative pressure pump 10 is turned off, the fixing screws at the four corners of the box plate are unscrewed, and the box plate is pulled out to clean or recycle the stratified shavings in the collection box 9.

[0034] In this embodiment of the invention, the negative pressure adsorption structure of "collecting cylinder 6 + guide pipe 8 + negative pressure pump 10" can accurately capture metal shavings generated during edge grinding, avoiding shavings splashing and polluting the working environment, while reducing secondary damage to the surface of the edge grinding mechanism and accessories, thus improving the edge grinding quality. Several filter plates 11 with gradually changing pore sizes can achieve layered collection of shavings, which is convenient for subsequent recycling according to particle size (e.g., small particles can be used for metal smelting and reuse, while large particles can be directly reprocessed). The box plate adopts a sliding design with screw fixing, which is convenient to disassemble, reduces cleaning difficulty, and improves the maintenance efficiency of the device. The collecting box 9 is slidably connected to the base 1, and the guide pipe 8 is slidably engaged with the collecting box 9, which not only ensures the stability of the collecting components during device operation, but also provides flexible space for the sliding plate 5 to drive the collecting cylinder 6 to adjust its position, adapting to the edge grinding needs of accessories of different sizes.

[0035] Example 2: Please refer to the appendix of the instruction manual. Figure 1 -5. As a preferred embodiment of the present invention, the auxiliary structure includes a feed pipe 20, which is fixedly installed on the top of the outer side of the collecting cylinder 6. The top of the collecting cylinder 6 is provided with a feed groove that cooperates with the feed pipe 20. A fixed cylinder 21 is fixedly installed at the bottom of the inner wall of the collecting cylinder 6 and below the feed pipe 20. A piston 22 is provided at the top of the fixed cylinder 21. The piston 22 is inserted into the interior of the fixed cylinder 21 and slidably connected to it. A return spring 23 is fixedly installed at the bottom of the piston 22. The end of the return spring 23 away from the piston 22 is fixedly connected to the collecting cylinder 6. The piston 22 is composed of a conical block, a sliding rod, and a square plate. The sliding rod and the square plate are slidably connected to the fixed cylinder 21.

[0036] The U-shaped base 2 is internally fixedly equipped with a first servo motor 12 and a guide rod. The output end of the first servo motor 12 is fixedly equipped with a first threaded rod 13, and the first threaded rod 13 is rotatably connected to the U-shaped base 2. The first threaded rod 13 passes through the slide plate 5 and is threadedly connected to it. The guide rod passes through the slide plate 5 and is slidably connected to it. A sealing ring is embedded on one side of the collection box 9 and at the junction of the collection box 9 and the guide pipe 8.

[0037] The top of the pressure plate 4 is provided with a second threaded rod 14. The inside of the U-shaped base 2 is rotatably connected to two gears 15, which mesh with each other. The top of the U-shaped base 2 is embedded with a second servo motor 16. The output end of the second servo motor 16 is fixedly connected to one of the gears 15. The inside of the other gear 15 is provided with a threaded cylinder, which passes through the other gear 15 and is fixedly connected to it. The threaded cylinder also passes through the top of the pressure plate 4 and is rotatably connected to it. The second threaded rod 14 passes through the threaded cylinder and is threadedly connected to it. The second threaded rod 14 is inserted into the inside of the pressure plate 4 and is rotatably connected to it. The inside of the pressure plate 4 is rotatably connected to a connecting plate 17. The second threaded rod 14 is fixedly connected to the connecting plate 17. A rubber pad is fixedly installed at the bottom of the pressure plate 4. The diameter of the connecting plate 17 is larger than the diameter of the second threaded rod 14.

[0038] Two fixing holes are provided on the top of the base 1 and on both sides corresponding to the edge grinding structure mounting groove 3. Several fixing holes are provided on the bottom of the inner wall of the U-shaped base 2 to facilitate the installation of the limiting plate, so that the limiting plate fits against the side of the metal part that needs to be edged for limiting. An L-shaped limiting block is provided on the side of the U-shaped base 2 away from the collecting cylinder 6, and the L-shaped limiting block is inserted into the interior of the U-shaped base 2 and slidably connected to it. A fixing screw is provided on the side of the U-shaped base 2 away from the edge grinding structure mounting groove 3, and the fixing screw is inserted into the interior of the U-shaped base 2 and threadedly connected to it. The fixing screw passes through the L-shaped limiting block and is threadedly connected to it.

[0039] An annular cover 19 is fixedly installed at the bottom of the U-shaped base 2. The annular cover 19 is inserted into the interior of the base 1 and slidably connected to it. A rubber pad is embedded at the top of the base 1 and at the junction of the base 1 and the annular cover 19. A third servo motor 18 is fixedly installed inside the base 1. A fixing rod is fixedly installed at the output end of the third servo motor 18 and is fixedly connected to the U-shaped base 2. The base 1 is rotatably connected to the fixing rod. A controller 24 is embedded on one side of the base 1. The controller 24 is electrically connected to the negative pressure pump 10, the first servo motor 12, the second servo motor 16 and the third servo motor 18.

[0040] In this embodiment of the invention, when the negative pressure pump 10 is started and a negative pressure is formed inside the collection cylinder 6, the negative pressure exerts a downward suction force on the piston 22, overcoming the elastic force of the return spring 23, and causing the piston 22 to slide downward along the inner wall of the fixed cylinder 21. At this time, the conical block at the top of the piston 22 separates from the bottom opening of the feed pipe 20, and the feed pipe 20 is connected to the inside of the collection cylinder 6. In addition to being directly sucked into the opening of the collection cylinder 6, some of the scattered fine debris generated by the edge grinding can enter the collection cylinder 6 through the feed pipe 20, further improving the debris collection range. After the edge grinding is completed, the negative pressure pump 10 is turned off, the negative pressure inside the collection cylinder 6 disappears, the return spring 23 returns to its deformation, and pushes the piston 22 upward, so that the conical block tightly fits the bottom opening of the feed pipe 20, sealing the feed pipe 20. At the same time, the slide rod and the square plate slide upward along the inner wall of the fixed cylinder 21 to ensure the stability of the piston 22's movement and prevent the debris already collected in the collection cylinder 6 from flowing back to the outside through the feed pipe 20.

[0041] Based on the size and grinding position of the metal parts to be ground, the first servo motor 12 is started by the controller 24. The output of the first servo motor 12 drives the first threaded rod 13 to rotate around its own axis. Since the first threaded rod 13 is threadedly connected to the slide plate 5 and the slide plate 5 is restricted from rotating by the guide rod, the rotation of the first threaded rod 13 is converted into linear motion of the slide plate 5 along the axis of the guide rod, which in turn drives the L-shaped support rod 7 and the collecting cylinder 6 to move synchronously, so as to achieve precise alignment between the opening of the collecting cylinder 6 and the grinding contact point. When the collecting cylinder 6 moves with the slide plate 5, the guide tube 8 slides synchronously in the collecting box 9. The sealing ring at the junction of the collecting box 9 and the guide tube 8 is always tightly attached to the outer wall of the guide tube 8, filling the gap between the two, preventing the negative pressure in the collecting box 9 from leaking, and ensuring that the collecting cylinder 6 has a stable adsorption force on the debris.

[0042] In this embodiment of the invention, the second servo motor 16 is started, and its output end drives the gear 15 connected to it to rotate. Through the meshing transmission of the gear 15, the other gear 15 and the threaded cylinder fixed inside rotate synchronously. Since the threaded cylinder is rotatably connected to the top of the pressure plate 4, and the second threaded rod 14 is threadedly connected to the threaded cylinder and fixed to the connecting plate 17 inside the pressure plate 4 at its bottom, the rotation of the threaded cylinder is converted into the downward movement of the second threaded rod 14 along the axial direction of the threaded cylinder. This pushes the connecting plate 17 to drive the pressure plate 4 to slide downward along the inner wall of the U-shaped base 2 until the rubber pad at the bottom of the pressure plate 4 is tightly attached to the top of the metal part to be ground, thereby achieving the clamping and fixing of the part. The second servo motor 16 is started in the opposite direction, and the gear 15 drives the threaded cylinder to rotate in the opposite direction. The second threaded rod 14 moves upward along the axial direction of the threaded cylinder, pulling the connecting plate 17 and the pressure plate 4 to slide upward synchronously, releasing the fixing of the part. The diameter of the connecting plate 17 is larger than the diameter of the second threaded rod 14, which can prevent the second threaded rod 14 from coming out of the pressure plate 4 and ensure the structural stability.

[0043] Based on the width of the metal part to be ground, select a suitable spacing of fixing holes at the bottom of the inner wall of the U-shaped base 2, and fix the two limiting plates to the corresponding fixing holes with bolts, so that the inner sidewall of the limiting plate fits tightly with the left and right sides of the part, limiting the lateral swaying or displacement of the part; if the part is large (exceeding the limiting range of the bottom of the inner wall of the U-shaped base 2), L-shaped limiting blocks can be used or replaced to further expand the lateral limiting range and ensure the stability of large parts.

[0044] When a metal part to be ground needs to undergo multi-sided grinding (such as grinding the four sides of a rectangular part in sequence), the controller 24 starts the third servo motor 18. The output of the third servo motor 18 drives the fixed rod to rotate around its own axis. Since the fixed rod is fixedly connected to the U-shaped base 2, and the U-shaped base 2 is slidably connected to the base 1 through the annular cover 19, the rotation of the fixed rod will drive the U-shaped base 2 and the parts, pressure plate 4, collection cylinder 6 and other components above it to rotate synchronously around the axis of the fixed rod. According to the grinding requirements, the controller 24 sets the rotation angle of the third servo motor 18. The motor drives the U-shaped base 2 to rotate to the preset angle and then stops automatically, so that the next surface to be ground of the part is facing the grinding mechanism in the grinding structure mounting groove 3. Multi-sided grinding can be completed without manual disassembly and adjustment of the part position.

[0045] The controller 24, acting as the "control center" of the device, enables the coordinated operation of various components: when starting the edge grinding operation, the controller 24 sequentially activates the second servo motor 16 (driving the pressure plate 4 to fix the accessories), the third servo motor 18 (adjusting the orientation of the edge grinding surface of the accessories), the first servo motor 12 (moving the collection cylinder 6 to align with the edge grinding point), and the negative pressure pump 10 (starting the chip collection). Each component is linked according to preset logic, reducing manual operation steps. During the edge grinding process, the controller 24 can adjust the rotation speed of the first servo motor 12 in real time (controlling the collection cylinder 6 to follow the edge grinding mechanism) and the rotation speed of the third servo motor 18 (adapting to different edge grinding rhythms). After the edge grinding is completed, the controller 24 can shut down all components with one click, improving operational convenience. At the same time, the controller 24 has a built-in overload protection module. When a component (such as the servo motor or the negative pressure pump 10) is overloaded, it will automatically cut off the power supply to that component and issue an alarm, protecting the device from damage.

[0046] When the U-shaped base 2 rotates, the annular cover 19 at the bottom slides synchronously along the annular groove of the base 1. The sliding fit between the annular cover 19 and the base 1 ensures smooth rotation and prevents external dust from entering the interior of the base 1. The rubber pad at the top of the base 1 fits tightly against the bottom of the annular cover 19. On the one hand, the elastic deformation of the rubber fills the tiny gap between the two, enhancing the sealing effect and preventing the third servo motor 18 and other components inside the base 1 from being contaminated by debris. On the other hand, the rubber pad can absorb the vibration generated when the U-shaped base 2 rotates, reducing the impact of vibration on the base 1 and the edge grinding mechanism, and improving the stability of the device operation.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
