Description

Technical Field

[0001] This invention relates to the field of workpiece processing, specifically to a polishing device for hardware workpieces. Background Technology

[0002] Hardware components refer to parts or products made of metal materials through processes such as stamping, casting, and cutting. They are core components of machinery, furniture, building structures, and daily necessities. They not only need precise dimensions and stable functionality, but their surface finish, such as smoothness, corrosion resistance, and aesthetics, directly determine the final quality and value of the product.

[0003] In the polishing process of hardware workpieces, a step-by-step processing method is often adopted to balance efficiency and effect: First, rough polishing is carried out using a sisal wheel with strong cutting force and a grease-like coarse polishing paste (commonly known as "butter") to quickly remove macroscopic defects such as tool marks and oxide scale on the surface; then fine polishing is carried out, using a soft and delicate impeller with a solid fine wax containing micro-abrasives to eliminate the fine scratches left by rough polishing, thereby obtaining a smooth and mirror-like high-gloss surface.

[0004] The above polishing process has defects: the workpiece needs to be physically transferred between two independent stations, rough polishing and fine polishing. This means that the same workpiece needs to be clamped, positioned and disassembled multiple times. At the same time, it is also necessary to frequently change lubricants and other tools. This repetitive interruption and preparation action reduces the pace of continuous production and makes the overall process cumbersome and inconvenient.

[0005] Therefore, a polishing device for hardware workpieces is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A metal workpiece polishing device according to this invention includes a worktable. The top of the worktable is slidably equipped with a trolley for controlling workpiece feeding, a turntable, a first power source for driving the turntable to rotate, a fixed housing, and a pair of suction ends both connected to the housing. The outer wall of the turntable is equipped with a pair of polishing wheels for polishing workpieces, a second power source for driving the polishing wheels to rotate, and a lubrication assembly for applying a coating to the polishing wheels. A fan is fixedly installed on the side of the housing away from the suction ends, and a mesh plate is fixedly installed inside. Through the combined action of the turntable and the pair of polishing wheels, the workpiece can be loaded on the trolley and then directly subjected to coarse and fine polishing at the turntable. This reduces the cumbersome operations caused by traditional station changes and repeated clamping, and also saves the workpiece's turnaround time between stations, making the polishing process more seamless.

[0008] Preferably, the lubrication assembly includes a fixed cavity fixedly disposed on the outer wall of the turntable; a pair of first sliding plates are symmetrically disposed on the inner wall of the fixed cavity; a lubricating component is fixedly disposed on one side of the pair of first sliding plates that are opposite to each other, and a spring is fixedly disposed between the other side and the inner wall of the fixed cavity; through the cooperative action of the first sliding plates, the spring, and the lubricating component, the first sliding plates and the lubricating component can apply wax to the polishing wheel under the combined action of gravity and the elastic force of the spring, so that when each polishing wheel is switched to the work station with the turntable, the corresponding type of lubricating component can be automatically preloaded, reducing the cumbersome operation of traditionally requiring the selection of lubricating components.

[0009] Preferably, the top of the fixed cavity is provided with a lifting plate and a third power source for controlling the radial movement of the lifting plate; the bottom of the lifting plate is fixedly provided with a pair of pull ropes respectively fixedly connected to the adjacent first slide plate; the pair of first slide plates and the retraction of the lubricant during waxing are controlled by a single power source. It is worth mentioning that the movement stroke of the lifting plate is limited. On the basis of ensuring that the lubricant is disengaged from the polishing wheel, it should be ensured that the compression amplitude of the spring is not too large, so as not to affect the service life of the spring.

[0010] Preferably, the inner wall of the fixed cavity is fixedly provided with a limiting ring for constraining the pull rope; by setting the limiting ring, the limiting ring can provide a limiting and isolation function for the pull rope when it is being pulled in or out, so as to reduce the direct contact between a pair of pull ropes and the resulting wear and entanglement.

[0011] Preferably, the fixing cavity has a Y-shaped structure with its end facing the center of the polishing wheel; the end face of the lubricant will contact the outer wall of the polishing wheel, and the contact method between the lubricant and the polishing wheel can be changed from the traditional line contact of waxing at the edges to the surface contact of waxing on the end face, which increases the waxing area of ​​the lubricant on the polishing wheel. On the one hand, it can make the consumption of the lubricant surface due to waxing more uniform and flat, and on the other hand, it can also improve the uniformity of the waxing area of ​​the lubricant on the polishing wheel.

[0012] Preferably, a pair of diamond dressers are symmetrically fixed on the top of the worktable; a pair of sliders for supporting the polishing wheel are slidably provided on the inner wall of the turntable; the sliders are controlled to slide to control the feed of the polishing wheel relative to the diamond dresser. During the process, the polishing wheel can be driven to rotate by controlling the second power source, so that the rough surface of the diamond dresser can dress the outer edge of the polishing wheel.

[0013] Preferably, the turntable has a second sliding plate and a fourth power source for driving the second sliding plate to slide radially on the side away from the polishing wheel; the outer wall of the second sliding plate is symmetrically provided with a connecting rod; the connecting rod and the outer wall of the adjacent slider are rotatably connected; after each working cycle, the polishing wheel can be dressed and its outer diameter reduced by a range B. On the one hand, this can keep the outer edge quality of the polishing wheel at its best and ensure the cutting force of the polishing wheel on the workpiece. On the other hand, it can quantify the service life of the polishing wheel by the remaining outer diameter, thereby making the life cycle of the polishing wheel more controllable and facilitating maintenance operations during the production process.

[0014] Preferably, the turntable has a pointer fixedly connected to the second slide plate on the side near the polishing wheel, and has multiple scales. The pointer is directly connected to the second slide plate, and the operator can determine the number of times the polishing wheel has been dressed by observing the readings on the scales on both sides of the pointer. This allows for a rough estimate of the remaining working life of the polishing wheel, so as to remind the operator to purchase polishing wheels in time or prepare to replace them.

[0015] Preferably, the suction end has a triangular cross-section; the suction end has a triangular cross-section with two straight sides and one arc side. The arc shape prevents the polishing wheel from interfering with the suction end during rotation. The top and side walls of the suction end are open. The top opening is used to absorb the debris generated when the diamond dresser trims the polishing wheel, and the side wall opening is used to absorb the debris generated when the polishing wheel polishes the workpiece. This configuration allows for dust removal from both processes using a single purification device.

[0016] Preferably, the top of the box is provided with a deflectable maintenance door; by providing a maintenance door, after the screen plate has been working for a long time, a layer of filter cake with accumulated debris will be attached to the surface. The staff can open the maintenance door to clean the outer wall of the screen plate, thus extending the service life of the screen plate.

[0017] The advantages of this invention are: 1. The hardware workpiece polishing equipment of the present invention, through the cooperation of a turntable and a pair of polishing wheels, allows the workpiece to be loaded on the trolley and then directly rough and fine polished at the turntable. On the one hand, it reduces the cumbersome operation caused by traditional station changes and repeated clamping, and on the other hand, it saves the turnaround time of the workpiece between stations, making the polishing process more closely connected.

[0018] 2. The hardware workpiece polishing equipment of the present invention, through the cooperation of the first slide plate, spring and lubricant, the first slide plate and lubricant can apply wax to the polishing wheel under the combined action of gravity and spring force, so that when each polishing wheel is switched to the work station with the turntable, the corresponding type of lubricant can be automatically preloaded, reducing the cumbersome operation of traditionally requiring the selection of lubricants.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 10As shown in the figure, a hardware workpiece polishing device according to an embodiment of the present invention includes a worktable 1. The top of the worktable 1 is slidably provided with a trolley 12 for controlling the workpiece feed, a turntable 13 and a first power source for driving the turntable 13 to rotate, a housing 16 and a pair of suction ends 15 both communicating with the housing 16 are fixedly provided; the outer wall of the turntable 13 is provided with a pair of polishing wheels 14 for polishing the workpiece, a second power source for driving the polishing wheels 14 to rotate, and a lubrication assembly for applying a coating to the polishing wheels 14; a fan 17 is fixedly provided on the side of the housing 16 away from the suction ends 15, and a mesh plate 18 is fixedly provided inside. During operation, the workpiece can be loaded and clamped by the trolley 12. The top of the trolley 12 can be equipped with an electric / pneumatic gripper to clamp the workpiece, and the X-axis movement module (such as a linear slide) can be used to feed the workpiece along the worktable 1. The top of the trolley 12 can be equipped with corresponding Y and Z axis movement modules (such as electric push rods) to control the feed of the workpiece in the Y and Z axes. The structures involved in the movement of the trolley 12 mentioned above are all mature technologies, so they will not be elaborated here. by Figure 1 and Figure 2 For example, the workpiece moves to turntable 13 and is braked. First, through the lubrication assembly and starting the second power source (such as a motor), wax (such as grease) is applied to the bottom rotating polishing wheel 14 (such as a sisal wheel). After waxing, the workpiece can be controlled by Y-axis feed to contact the bottom polishing wheel 14 and be coarsely polished. After coarse polishing, the workpiece can be controlled to move down and reset, and the turntable 13 can be controlled to rotate by starting the first power source (such as a stepper motor). Figure 2 For example, rotate 120° clockwise to replace the position of a pair of polishing wheels 14. Then repeat the above steps to apply wax (such as fine wax) to the polishing wheel 14 (such as a wind cloth wheel) that is rotating at the bottom. After the wax is applied, drive the workpiece to be finely polished by the polishing wheel 14. This completes all the polishing processes in a single clamping process of the workpiece. In addition, during the polishing process, the blower 17 can be turned on to drive the box 16 and the directly connected suction end 15 to generate negative pressure. The pair of suction ends 15 can absorb the debris generated when polishing the polishing wheel 14 and the workpiece through the opening in the outer wall. The debris can enter the box 16 through the suction end 15 and be intercepted by the mesh plate 18. It is worth mentioning that the bottom height of the suction end 15 should be higher than the lowest point of the polishing wheel 14, that is, the suction end 15 will not cause spatial interference with the workpiece. Through the combined action of the turntable 13 and a pair of polishing wheels 14, the workpiece can be loaded on the trolley 12 and then directly polished at the turntable 13. This reduces the tedious operations caused by traditional station changes and repeated clamping, and also saves the turnaround time of the workpiece between stations, making the polishing process more closely connected.

[0025] Please see Figures 4 to 9As shown, the lubrication assembly includes a fixed cavity 2 fixedly disposed on the outer wall of the turntable 13; a pair of first sliding plates 22 are symmetrically disposed on the inner wall of the fixed cavity 2; a lubricating element 24 is fixedly disposed on one side of the pair of first sliding plates 22 that are opposite to each other, and a spring 23 is fixedly disposed between the other side and the inner wall of the fixed cavity 2. by Figure 8 For example, when the spring 23 is in a compressed state, the component consisting of the first sliding plate 22 and the lubricant 24 located near the bottom polishing wheel 14 can press against the outer wall of the polishing wheel 14 under the combined action of gravity and the elastic force of the spring 23. Here, the pair of lubricants 24 correspond to the types required for polishing adjacent polishing wheels 14. That is, in the rough polishing process, the polishing wheel 14 and the lubricant 24 correspond to the sisal wheel and grease wheel, respectively. In the fine polishing process, the polishing wheel 14 and the lubricant 24 correspond to the air cloth wheel and fine wax wheel, respectively. Before polishing the workpiece, the first sliding plate 22 can be controlled to move down and the second power source can be started to drive the polishing wheel 14 to rotate idling. During the process, the lubricant 24 can be coated with wax by squeezing the outer wall of the rotating polishing wheel 14. After the waxing is completed, the first sliding plate 22 can be controlled to move up and reset so that the lubricant 24 moves away from the polishing wheel 14 and stops the waxing. It is worth mentioning that the lubricant 24 and the first sliding plate 22 can be connected by a clamp to hold the lubricant 24 and then fixed to the first sliding plate 22 by rivets. This will not be elaborated here. Through the combined action of the first slide plate 22, spring 23, and lubricant 24, the first slide plate 22 and lubricant 24 can apply wax to the polishing wheel 14 under the combined action of gravity and the elastic force of spring 23. This allows the corresponding type of lubricant 24 to be automatically preloaded when each polishing wheel 14 is switched to the work station with the turntable 13, reducing the tedious operation of traditionally requiring the selection of lubricant 24.

[0026] Please see Figures 7 to 9 As shown, the top of the fixed cavity 2 is provided with a lifting plate 3 and a third power source for controlling the radial movement of the lifting plate 3; the bottom of the lifting plate 3 is fixedly provided with a pair of pull ropes 32 respectively fixedly connected to the adjacent first slide plate 22. When it is necessary to control the first sliding plate 22 to move upward, the lifting plate 3 can be controlled to move upward by activating a third power source (such as a cylinder). Figure 9 For example, when the lifting plate 3 moves upward, the lifting rope 32 can be pulled to simultaneously pull a pair of first sliding plates 22, so that the first sliding plates 22 can drive the lubricating component 24 into the fixed cavity 2 and away from the polishing wheel 14. This setting can control the retraction of a pair of first sliding plates 22 and the lubricating component 24 when waxing with a single power. It is worth mentioning that the moving stroke of the lifting plate 3 is limited. On the basis of ensuring that the lubricating component 24 is disengaged from the polishing wheel 14, it should be ensured that the compression amplitude of the spring 23 is not too large, so as not to affect the service life of the spring 23.

[0027] Please see Figures 7 to 9As shown, a limiting ring 4 for constraining the pull rope 32 is fixedly provided on the inner wall of the fixed cavity 2; By setting a limiting ring 4, the limiting ring 4 can provide a limiting and isolation function for the pull rope 32 when it is being pulled in or out, so as to reduce the direct contact between a pair of pull ropes 32 and the resulting wear and entanglement.

[0028] Please see Figure 8 As shown, the fixing cavity 2 has a Y-shaped structure, and its end faces the center of the polishing wheel 14; When the lubricant 24 applies wax to the polishing wheel 14, the central axis of the lubricant 24 is a ray from the center of the polishing wheel 14. That is, the end face of the lubricant 24 will contact the outer wall of the polishing wheel 14. The contact method between the lubricant 24 and the polishing wheel 14 can be changed from the traditional line contact of waxing at the edges to the surface contact of waxing on the end face. This increases the waxing area of ​​the lubricant 24 on the polishing wheel 14. On the one hand, it can make the consumption caused by waxing on the surface of the lubricant 24 more uniform and smooth. On the other hand, it can also improve the uniformity of the waxing area of ​​the lubricant 24 on the polishing wheel 14.

[0029] Please see Figures 1 to 4 As shown, a pair of diamond dressing tools 6 are symmetrically fixed on the top of the workbench 1; a pair of sliders 62 are slidably provided on the inner wall of the turntable 13 for supporting the polishing wheel 14. After prolonged use, the outer edge of polishing wheel 14 may become uneven, reducing its roundness. A certain working time period (the specific time can be determined by the actual usage frequency, for example, 4 days for the lifting plate 3 and the limiting ring) is used as a cycle. After the cycle period ends, the outer edges of the two polishing wheels 14 can be dressed using the diamond dresser 6. Specifically, this can be achieved by controlling the first power source to drive the turntable 13 to rotate, so that the pair of polishing wheels 14 are in a horizontal position (e.g., from...). Figure 2 Switch to Figure 5 Turntable 13 rotates 60° clockwise, and then slider 62 can be controlled to slide to control the feed of polishing wheel 14 relative to diamond dresser 6. During the process, the polishing wheel 14 can be rotated by controlling the second power source so that the rough surface of diamond dresser 6 can dress the outer edge of polishing wheel 14.

[0030] Please see Figures 1 to 5 As shown, the turntable 13 is provided with a second slide plate 7 and a fourth power source for driving the second slide plate 7 to slide radially on the side away from the polishing wheel 14; the outer wall of the second slide plate 7 is symmetrically provided with a connecting rod 72; the connecting rod 72 and the outer wall of the adjacent slider 62 are rotatably connected. When polishing wheel 14 needs to be dressed, Figure 3For example, the second slide plate 7 can be moved downward by one range A by starting the fourth power source (e.g., an electric cylinder). During the downward movement of the second slide plate 7, the connecting rods 72 on both sides can be driven to deflect outward and push the sliders 62 on both sides to slide outward by one range B. This drives the rotating polishing wheel 14 to contact the diamond dresser 6 and be dressed by it. After the dressing is completed, the outer diameter of the polishing wheel 14 will be reduced by one range B. With this setting, the polishing wheel 14 can be dressed and its outer diameter reduced by one range B after each work cycle. On the one hand, the outer edge quality of the polishing wheel 14 can be kept at its best to ensure the cutting force of the polishing wheel 14 on the workpiece. On the other hand, the service life of the polishing wheel 14 can be quantified by the remaining outer diameter, thereby making the life cycle of the polishing wheel 14 more controllable and facilitating maintenance operations during the production process.

[0031] Please see Figure 4 As shown, the turntable 13 is provided with a pointer 8 fixedly connected to the second slide plate 7 on the side near the polishing wheel 14, and has multiple scales 82. The pointer 8 is directly connected to the second slide plate 7. By observing the readings on the scale 82 indicated by the pointer 8, the staff can determine how many times the polishing wheel 14 has been dressed. This allows them to roughly estimate the remaining working life of the polishing wheel 14 and remind the staff to purchase polishing wheels 14 in a timely manner or prepare to replace them.

[0032] Please see Figure 5 and Figure 6 As shown, the cross-section of the suction end 15 is arranged in a triangular shape; The suction end 15 has a triangular cross-section with two straight sides and one curved side. The curved design prevents the polishing wheel 14 from interfering with the suction end 15 during rotation. The top and side walls of the suction end 15 are open. The top opening is used to absorb the debris generated by the diamond dresser 6 when trimming the polishing wheel 14, and the side wall opening is used to absorb the debris generated by the polishing wheel 14 when polishing the workpiece. This design allows for dust collection for both processes using a single purification device.

[0033] Please see Figure 5 and Figure 6 As shown, the top of the box 16 is provided with a deflectable access door 10; By setting up the inspection door 10, after the screen plate 18 has been working for a long time, a layer of filter cake with accumulated debris will be attached to its surface. The staff can open the inspection door 10 to clean the outer wall of the screen plate 18 and extend the service life of the screen plate 18.

[0034] Based on the above, the working logic of this application during workpiece polishing is as follows: S1. Workpiece fixing and feeding: The workpiece is manually placed above the trolley 12, and the workpiece is clamped by the electric gripper integrated on the top of the trolley 12. Then, the trolley 12 is moved to the turntable 13 by the X-axis moving module and then braked. S2, Coarse Polishing: Start the first power source to switch the polishing wheel 14 responsible for coarse polishing to the bottom. After switching, start the third power source to release the active traction of the lifting plate 3 and the pull rope 32 on the first slide plate 22, drive the lubricating component 24 to press against the polishing wheel 14 under the action of the spring 23 and its own weight, and start the second power source to drive the polishing wheel 14 to idle, so that the lubricating component 24 can apply wax to the polishing wheel 14. After the waxing is completed, the third power source can be started to reset and move the lubricating component 24 away from the polishing wheel 14. Then, the workpiece is lifted by the Z-axis moving module integrated on the trolley 12 and coarsely polished by the polishing wheel 14. The X-axis moving module drives the workpiece to move laterally relative to the polishing wheel 14 to polish the workpiece surface evenly. When the workpiece is wide, the Y-axis moving module can be used to polish the other surfaces of the workpiece. S3. Fine polishing: After coarse polishing is completed, the first power source is started to switch the polishing wheel 14 responsible for fine polishing to the bottom. After the switch is completed, the same as in S2, the third power source is started to drive the lubricating component 24 to apply wax to the polishing wheel 14. The lubricating component 24 is then moved away from the polishing wheel 14 by the third power source. Then, the workpiece can be moved in a plane relative to the polishing wheel and fine polishing can be performed by the X, Y, and Z axis moving modules on the trolley 12. After fine polishing is completed, the polishing process of the workpiece can be completed. S4. Polishing wheel dressing: When the polishing wheel 14 needs to be dressed, the first power source can be started to adjust the pair of polishing wheels 14 to the same horizontal height. Then, the second slide plate 7 can be controlled to move radially through the fourth power source, and the pair of rotating polishing wheels 14 can be controlled to move outward toward the diamond dresser 6 and be dressed by it. After dressing is completed, the pair of polishing wheels 14 can be reset through the fourth power source.

[0035] The above working logic can be centrally scheduled and controlled by a PLC, which is a mature application of system control in this field, so it will not be elaborated here.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
