Description

Technical Field

[0001] This application relates to the field of polishing and grinding, and in particular to a high-precision wooden handle curved surface polishing and grinding device. Background Technology

[0002] Polishing refers to the process of polishing and grinding the surface of a workpiece to reduce its roughness and achieve a bright, smooth finish. Workers typically use polishing equipment to perform this process.

[0003] In related technologies, polishing equipment includes a frame with an abrasive mechanism mounted on it. The abrasive mechanism includes a fixing component for securing the workpiece and a polishing assembly for polishing the workpiece. The operator places the workpiece on the fixing component, and then the polishing assembly polishes it. After polishing, the operator removes the workpiece and places it in a storage area. The polishing assembly includes a first rotating motor, a transmission wheel, a tensioning wheel, and a sanding belt. The shaft of the first rotating motor is connected to the transmission wheel. The sanding belt is fitted onto both the transmission wheel and the tensioning wheel, with its outer surface in contact with the workpiece. Starting the first rotating motor rotates the transmission wheel, which in turn rotates the sanding belt and the tensioning wheel. The transmission wheel and the tensioning wheel work together to tension the sanding belt, thereby polishing the surface of the workpiece, particularly wood.

[0004] Regarding the aforementioned technologies, the inventors believe that the typical tensioning wheel is a common cylindrical shape, which is easy to polish into a flat surface, but not easy to polish into a smooth curved surface. Summary of the Invention

[0005] To improve the polishing effect of curved surfaces, this application provides a high-precision wooden handle curved surface polishing device.

[0006] The abrasive device provided in this application adopts the following technical solution:

[0007] A high-precision wooden handle curved surface polishing device includes a frame, on which an abrasive mechanism is mounted. The abrasive mechanism includes a polishing component for polishing the workpiece and a fixing component for fixing the workpiece. The polishing component includes a first rotating motor, a transmission wheel, a tensioning wheel, and an abrasive belt. The shaft of the first rotating motor is connected to the transmission wheel. The abrasive belt is simultaneously fitted onto the transmission wheel and the tensioning wheel. The outer surface of the abrasive belt abuts against the workpiece. The tensioning wheel contracts inward from the middle to both ends along its own axial direction, and the peripheral sidewall of the tensioning wheel is arc-shaped. There are at least two tensioning wheels.

[0008] By adopting the above technical solution, because the tensioning wheel contracts inward from the center to both ends along its own axial direction, and the peripheral wall of the tensioning wheel is arc-shaped, the surface of the tensioned abrasive belt is also curved. Furthermore, the surface of the abrasive belt moves away from the workpiece surface from the center to both sides along the width of the abrasive belt, thus reducing the contact area between the abrasive belt and the workpiece. While a conventional cylindrical tensioning wheel results in surface contact between the abrasive belt and the workpiece, the arc-shaped tensioning wheel results in line contact, improving the polishing accuracy. In addition, the ends of a regular cylindrical tensioning wheel are angular. The ends of a regular cylindrical tensioning wheel are always in contact with the workpiece surface through the abrasive belt, which can easily affect the polishing of the curved surface of the workpiece. However, the tensioning wheel contracts inward from the middle to both ends along its own axial direction, making room for the contact between the abrasive belt and the workpiece surface, reducing the impact of the ends of the tensioning wheel on the polishing of the curved surface of the workpiece. Moreover, its own arc shape ensures that the contact between the abrasive belt and the workpiece is always arc-shaped, which facilitates polishing a smooth curved surface and improves the polishing effect of the workpiece surface.

[0009] Optionally, the polishing assembly further includes a mounting housing, on which the first rotating motor is mounted, and the transmission wheel, tension wheel, and sanding belt are all disposed inside the mounting housing. A processing opening is provided on the side wall of the mounting housing, the processing opening facing the workpiece, and the contact surface between the sanding belt and the workpiece is located outside the mounting housing. The mounting housing is slidably disposed, and can slide along the length direction of the workpiece, and can also slide towards or away from the peripheral side wall of the workpiece.

[0010] By adopting the above technical solution, the mounting shell carries the sanding belt and slides along the length of the workpiece, so that the sanding belt can automatically process the length of the workpiece. The distance that the mounting shell carries the sanding belt and slides along the length of the workpiece is set according to the actual situation, and the sanding belt is controlled to move along the length of the workpiece while moving towards or away from the workpiece, so that the contact time between the sanding belt and different parts of the workpiece surface is different, which makes it easier for the sanding belt to polish the surface of the workpiece into a curved surface.

[0011] Optionally, the mounting housing is provided with an adjusting wheel, which is slidably disposed. The adjusting wheel can slide to abut against the peripheral wall of the adjusting wheel and the surface of the sanding belt to tension the sanding belt. The adjusting wheel can also slide to a state where the sanding belt is untensioned.

[0012] By adopting the above technical solution, when it is necessary to replace the sanding belt, the adjusting wheel is slid to disengage from the surface of the sanding belt and the tension of the sanding belt is released, making it easier to remove and replace the sanding belt. After the sanding belt is fitted onto the tensioning wheel and the drive wheel, the adjusting wheel is slid to disengage from the surface of the sanding belt and the sanding belt is tensioned, so that the sanding belt is stably installed.

[0013] Optionally, the fixing member includes opposing abutments, which slide toward each other or toward each other. When the two abutments slide toward each other, the abutment surfaces that are close to each other abut against the two ends of the workpiece along its length. The abutments are rotatably configured.

[0014] By adopting the above technical solution, the two abutment rods are first slid away from each other, and then the worker places the workpiece at the abutment rods. Then the two abutment rods are driven to slide away from each other, which can hold the workpiece in place. The sliding distance of the abutment rods can be set according to the actual situation to adapt to workpieces of different lengths. The rotation of the abutment rods drives the workpiece to rotate, so that the circumference of the workpiece can be polished.

[0015] Optionally, the frame is provided with a feeding device, which includes a storage component, a baffle mechanism, and a feeding component for sending the workpiece to the polishing assembly. The storage component is located on the side of the abutment away from the sanding belt. The storage component is a storage plate, which is vertically arranged. The storage plate includes a first plate and a second plate. The first plate is arranged opposite to each other, and the second plate is correspondingly arranged on both sides of the first plate in the width direction. The distance between the two second plates is adapted to the width of the workpiece. The second plates are located on the side of the first plates that are close to each other.

[0016] The material blocking mechanism is located below the storage component, and the material blocking mechanism is used to lower a specified number of workpieces at the storage component each time.

[0017] By adopting the above technical solution, the workers can put multiple workpieces down from the top of the first plate along the space between the two second plates. The two ends of the workpieces are located at the opposite ends of the first plate. The material blocking mechanism causes a specified number of workpieces to fall down from the storage part each time. Then, the feeding component transports the workpieces to the stop bar. This eliminates the need for workers to manually load the workpieces every time they process them, saving manpower, improving the degree of automation, and increasing the loading efficiency.

[0018] Optionally, the feeding assembly includes a pneumatic gripper and a support plate. The pneumatic gripper is disposed on the support plate, the support plate is slidably disposed, the support plate slides toward the side wall of the push rod, and the pneumatic gripper is raised and lowered.

[0019] By adopting the above technical solution, the pneumatic gripper clamps the workpiece after sliding and lifting, and then moves to the stop bar by sliding and lifting, thus realizing the feeding process of the feeding component. The stop bar first slides away from each other. When the workpiece moves to the stop bar, the stop bar slides towards each other and stops the workpiece. Then the pneumatic gripper moves back to its original position.

[0020] Optionally, each of the first plates corresponds to a material blocking mechanism. The material blocking mechanism includes a first baffle, a second baffle, a push rod, and a linkage assembly. The first baffle is located below the second plate. The distance between the top surface of the first baffle and the bottom surface of the second plate is consistent with the total thickness of the specified number of workpieces that will fall. A clearance slot is provided on the top surface of the first baffle. One end of the push rod is connected to the support plate through the linkage assembly, and the other end of the push rod passes through the clearance slot. The push rod pushes the specified number of workpieces on the first baffle toward the direction close to the abutment rod.

[0021] The push rod passes through the clearance groove and is connected to a support plate. The support plate is located on the side of the first baffle away from the push rod. The support plate is used to support the workpieces behind a specified number of workpieces.

[0022] The second baffle is located below the first baffle. The second baffle is slidably disposed. The second baffle can slide until the workpiece pushed by the push rod is on the second baffle. The second baffle can also slide until it is no longer in contact with the workpiece pushed by the push rod. The pneumatic gripper is located below the workpiece after it has passed the second baffle.

[0023] By adopting the above technical solution, the linkage component drives the push rod to slide within the clearance groove. The push rod pushes a specified number of workpieces on the first baffle towards the direction close to the abutment. At this time, the support plate supports the workpieces behind the specified number of workpieces, reducing the impact of the workpieces behind the specified number of workpieces on the push rod returning to its original position. After the specified number of workpieces fall onto the second baffle, the pneumatic gripper is driven to move to the second baffle to clamp the specified number of workpieces. Then, the second baffle is slid to disengage from the workpieces pushed by the push rod. Then, the pneumatic gripper moves the workpieces to the abutment for polishing. This achieves the goal of the material blocking mechanism causing a specified number of workpieces to descend from the storage position each time.

[0024] Optionally, the first plate is slidably configured such that the first plate can slide toward each other in a direction that brings them closer together, or the first plate can slide toward each other in a direction that moves them further apart.

[0025] By adopting the above technical solution, when the length of the workpiece changes, the distance between the two opposing first plates can be adjusted by sliding the first plate, which is convenient to adapt to workpieces of different lengths.

[0026] Optionally, the first plate has a first adjusting groove, the length direction of the first adjusting groove is parallel to the width direction of the first plate, the end of the second plate near the first plate extends outward in a direction away from each other, the edge is connected to the edge, the length of the first adjusting groove is greater than the distance between the two first adjusting bolts, the rod of the first adjusting bolt passes through the edge and the first adjusting groove and is threaded to a first adjusting nut, the first adjusting nut abuts against the first plate.

[0027] By adopting the above technical solution, when the width of the workpiece changes, the first adjusting nut and the first adjusting bolt are disengaged, the first adjusting bolt is disengaged from the first adjusting slot, the second plate is moved to a suitable position according to the width of the workpiece, the first adjusting bolt is passed through the edge and the first adjusting slot, and the first adjusting nut is rotated onto the first adjusting bolt and the first adjusting nut and the first plate are abutted, thereby fixing the edge and the first plate.

[0028] Optionally, the mounting housing is provided with a dust collection component, which includes a fan and a connecting pipe. One end of the connecting pipe is connected to the inside of the mounting housing, and the other end of the connecting pipe is connected to the air inlet of the fan.

[0029] By adopting the above technical solution, the blower is started to suck away the waste generated during the polishing process, reducing the impact of waste on the polishing process and improving the cleanliness of the working environment.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Because the tensioning wheel contracts inward from the center to both ends along its own axial direction, and its peripheral sidewalls are arc-shaped, the surface of the tensioned abrasive belt is also curved. Furthermore, the surface of the abrasive belt moves away from the workpiece surface from the center to both sides along the width of the belt, reducing the contact area between the abrasive belt and the workpiece. With a standard cylindrical tensioning wheel, the contact between the abrasive belt and the workpiece is surface contact, while with a tensioning wheel whose surface is arc-shaped, the contact between the abrasive belt and the workpiece is line contact, improving the polishing accuracy. Additionally, the ordinary cylindrical tensioning wheel... The ends of the cylindrical tensioning wheel are angular. The ends of a regular cylindrical tensioning wheel are always in contact with the workpiece surface through the abrasive belt, which can easily affect the polishing of the curved surface of the workpiece. However, the tensioning wheel contracts inward from the middle to both ends along its own axial direction, making room for the contact between the abrasive belt and the workpiece surface. This reduces the impact of the ends of the tensioning wheel on the polishing of the curved surface of the workpiece. In addition, its own arc shape ensures that the contact between the abrasive belt and the workpiece is always arc-shaped, which facilitates the polishing of a smooth curved surface and improves the polishing effect of the workpiece surface.

[0032] 2. When the sanding belt needs to be replaced, slide the adjusting wheel until the side wall of the adjusting wheel and the surface of the sanding belt are no longer in contact and release the tension of the sanding belt, so that the sanding belt can be removed and replaced. After the sanding belt is fitted onto the tensioning wheel and the drive wheel, slide the adjusting wheel until the side wall of the adjusting wheel and the surface of the sanding belt are in contact and the sanding belt is tensioned, so that the sanding belt is stably installed.

[0033] 3. The worker places multiple workpieces from the top of the first plate along the space between the two second plates. The two ends of the workpieces are located at the opposite ends of the first plate. The material blocking mechanism causes a specified number of workpieces to descend from the storage position each time. Then, the feeding component transports the workpieces to the stop bar. This eliminates the need for the worker to manually load the workpieces every time they are processed, saving labor, improving automation, and increasing loading efficiency.

[0044] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0045] This application discloses a high-precision wooden handle curved surface polishing device. (Refer to...) Figure 1 and Figure 2The high-precision wooden handle curved surface polishing equipment includes a frame 1, on which an abrasive mechanism 2 and a feeding device 3 are mounted. The feeding device 3 is used to feed the workpiece to the abrasive mechanism 2. The abrasive mechanism 2 includes a polishing assembly 21 for polishing the workpiece and a fixing component 22 for fixing the workpiece. The polishing assembly 21 includes a mounting shell 211, a first rotating motor 212, a transmission wheel 213, a tension wheel 214, and a sanding belt 215. A first mounting plate 4 is fixedly connected to the side wall of the mounting shell 211. The first rotating motor 212 is fixedly mounted on the first mounting plate 4. The transmission wheel 213, the tension wheel 214, and the sanding belt 215 are all located inside the mounting shell 211. The transmission wheel 213 and the tension wheel 214 are rotatably connected to the side wall of the mounting shell 211. A processing port 2111 is opened on the side wall of the mounting shell 211, facing the workpiece. The contact surface between the sanding belt 215 and the workpiece is located on the mounting shell 211. In addition, the shaft of the first rotating motor 212 passes through the side wall of the mounting shell 211 and is fixedly connected to the transmission wheel 213. The first rotating motor 212 and the mounting shell 211 are rotatably connected. In this embodiment, there are three tensioning wheels 214. The three tensioning wheels 214 and one transmission wheel 213 form a triangle. The three tensioning wheels 214 are arranged in a vertical array and are closer to the workpiece than the transmission wheel 213. The sanding belt 215 is simultaneously sleeved on the transmission wheel 213 and the tensioning wheels 214. One transmission wheel 213 and three tensioning wheels 214 work together to tension the sanding belt 215 so that the surface of the sanding belt 215 abuts against the surface of the workpiece.

[0046] Reference Figure 2 The mounting shell 211 is designed to slide along the length of the workpiece during processing, allowing the abrasive belt 215 to automatically process the workpiece along its length. The mounting shell 211 can also slide towards or away from the workpiece's sidewall. The distance and time the mounting shell 211, carrying the abrasive belt 215, slides along the workpiece's length can be set according to actual conditions. This controls the abrasive belt 215 to move along the workpiece's length while simultaneously moving towards or away from it, resulting in varying contact times between the abrasive belt 215 and different parts of the workpiece surface. This facilitates the abrasive belt 215 polishing the workpiece surface to create curved surfaces. The first rotating motor 212 is started, driving the transmission wheel 213 to rotate, which in turn drives the abrasive belt 215 and the tension wheel 214. The transmission wheel 213 and the tension wheel 214 work together to tension the abrasive belt 215, which polishes the workpiece surface as it rotates.

[0047] Reference Figure 2The tensioning wheel 214 contracts inward from the center to both ends along its own axial direction, forming an elliptical shape. The peripheral walls of the tensioning wheel 214 are also arc-shaped, causing the surface of the tensioned abrasive belt 215 to also be curved. Furthermore, the surface of the abrasive belt 215 moves away from the workpiece surface from the center to both sides along the width direction of the abrasive belt 215, reducing the contact area between the abrasive belt 215 and the workpiece. While a conventional cylindrical tensioning wheel 214 results in surface contact between the abrasive belt 215 and the workpiece, the arc-shaped tensioning wheel 214 results in line contact, improving the polishing efficiency. In addition to improving grinding precision, the ends of a conventional cylindrical tension wheel 214 are angular. Since the ends of a conventional cylindrical tension wheel 214 are always in contact with the workpiece surface via the abrasive belt 215, this can easily affect the polishing of curved surfaces. However, the tension wheel 214, by contracting inwards from the center towards both ends along its axial direction, allows more space for the abrasive belt 215 to contact the workpiece surface, reducing the impact of the ends of the tension wheel 214 on the polishing of curved surfaces. Furthermore, its arc shape ensures that the contact between the abrasive belt 215 and the workpiece remains arc-shaped, facilitating the polishing of smooth curved surfaces. In this embodiment, the shape of the transmission wheel 213 matches the shape of the tension wheel 214, further facilitating the polishing of smooth curved surfaces and improving the polishing effect on the workpiece surface.

[0048] Reference Figure 2 An adjusting wheel 216 is installed on the mounting housing 211. The adjusting wheel 216 is located on the side away from the workpiece and is slidably set. A first telescopic cylinder 2161 is fixedly installed on the inner wall of the mounting housing 211. A positioning plate 2162 is fixedly connected to the piston rod of the first telescopic cylinder 2161. The adjusting wheel 216 and the positioning plate 2162 are rotatably connected. The adjusting wheel 216 can slide to abut against the surface of the sanding belt 215 on its peripheral side wall and tighten the sanding belt 215. The adjusting wheel 216 can also slide to release the tension of the sanding belt 215. When the sanding belt 215 needs to be replaced, the first telescopic cylinder 2161 is driven to retract, causing the adjusting wheel 216 to slide until it disengages from the surface of the sanding belt 215 and releases the tension of the sanding belt 215, making it easier to remove and replace the sanding belt 215. After the sanding belt 215 is fitted onto the tensioning wheel 214 and the transmission wheel 213, the first telescopic cylinder 2161 is driven to extend, causing the adjusting wheel 216 to slide until it abuts against the surface of the sanding belt 215 and tensions the sanding belt 215, ensuring a stable installation of the sanding belt 215.

[0049] Reference Figure 2As shown in Figure 3, the side wall of the mounting shell 211 on one side in the width direction is rotatably connected to the main body of the mounting shell 211 to form an opening and closing door 2112. A fixing rod 2113 is fixedly connected to the inner wall of the mounting shell 211 near the machining port 2111. The fixing rod 2113 is "L" shaped. A fixing hole 2114 is opened on the inner wall of the opening and closing door 2112 near the machining port 2111. The horizontal section of the fixing rod 2113 passes into the fixing hole 2114 to close the opening and closing door 2112. The opening and closing door 2112 is opened by rotating the opening and closing door 2112 until the fixing rod 2113 is disengaged from the fixing hole 2114, which facilitates the replacement of the sanding belt 215.

[0050] Reference Figure 4 A dust collection assembly 5 is installed on the mounting housing 211. The dust collection assembly 5 is located on the side away from the processing port 2111. The dust collection assembly 5 includes a fan 51 and a connecting pipe 52. The connecting pipe 52 is connected to the side of the mounting housing 211 away from the processing port 2111. One end of the connecting pipe 52 is connected to the inside of the mounting housing 211, and the other end of the connecting pipe 52 is connected to the air inlet of the fan 51. When the fan 51 is started, the waste generated during the polishing process is sucked away, reducing the impact of waste on the polishing process and improving the cleanliness of the working environment.

[0051] Reference Figure 4 and Figure 5The frame 1 is equipped with a first sliding assembly 41 for driving the polishing assembly 21 to slide along the length of the workpiece. The first sliding assembly 41 includes a second rotary motor 411, a first screw 412, and a first slider 413. The second rotary motor 411 is fixedly mounted on the top surface of the frame 1. A second mounting plate 414 is fixedly mounted on the top surface of the frame 1. The second mounting plate 414 is arranged along the length of the workpiece during processing. A first groove 415 is formed on the top surface of the second mounting plate 414 along its own length. The shaft of the second rotary motor 411 passes through the second mounting plate. The side wall of 414 is fixedly connected to one end of the first screw 412. The shaft of the second rotating motor 411 is rotatably connected to the second mounting plate 414. The end of the first screw 412 away from the second rotating motor 411 is rotatably connected to the inner wall of the first slide groove 415 on the side away from the second rotating motor 411 in the length direction. The first slider 413 is T-shaped. The vertical section of the first slider 413 slides in the first slide groove 415. The end of the first screw 412 away from the second rotating motor 411 passes through the vertical section of the first slider 413 and is threadedly connected to the first slider 413. A second slide groove 4131 is provided on the top surface of the first slider 413. The second slide groove 4131 is in the shape of an inverted T. A sliding block 4132 is fixedly connected to the bottom surface of the first mounting plate 4. The sliding block 4132 is in the shape of an inverted T. The second slide groove 4131 and the sliding block 4132 are adapted to each other. The sliding block 4132 slides in the second slide groove 4131. A second telescopic cylinder 416 is fixedly installed on the side wall of the first slider 413 away from the workpiece during processing. The piston rod of the second telescopic cylinder 416 is fixedly connected to the side wall of the first mounting plate 4.

[0052] Start the second rotary motor 411 to drive the first screw 412 to rotate, which in turn drives the first slider 413 to slide along the length of the workpiece, and drives the first mounting plate 4 to slide along the length of the workpiece, so that the mounting shell 211 carrying the sand belt 215 slides along the length of the workpiece; start the second telescopic cylinder 416 to drive the first mounting plate 4 to move toward or away from the workpiece.

[0053] Reference Figure 2 and Figure 4The fixing member 22 includes two opposing abutment rods 221, which are located at both ends of the workpiece along its length. The two abutment rods 221 can slide towards each other or away from each other. When the two abutment rods 221 slide towards each other, the surfaces of the two abutment rods 221 that are close to each other abut against the two ends of the workpiece along its length, thereby fixing the workpiece along its length. When the two abutment rods 221 slide away from each other, the abutment rods 221 disengage from the workpiece, releasing the workpiece. The sliding distance of the abutment rods 221 can be set according to the actual situation to facilitate fixing workpieces of different lengths. Two third sliders 222 are slidably connected to the frame 1. One third slider 222 corresponds to one abutment 221. A positioning block 223 is fixedly installed on the top surface of the frame 1. One positioning block 223 corresponds to one abutment 221. A third groove 2231 is opened on the top surface of the positioning block 223. One third groove 2231 corresponds to one third slider 222. The third slider 222 is "T" shaped. The vertical section of the third slider 222 slides within the third groove 2231. Each third slider 222... A support block 224 is fixedly connected to the top surface of the three sliders 222. The abutment rod 221 passes through the support block 224 along its own length and is rotatably connected to the support block 224. A third telescopic cylinder 225 is fixedly installed on the side of the third slider 222 that is far away from each other. The piston rod of the third telescopic cylinder 225 is fixedly connected to the side of the third slider 222 that is far away from each other, so as to drive the third slider 222 to slide. The sliding of the third slider 222 causes the support block 224 to slide, thereby causing the abutment rod 221 to slide. A feeding groove 11 is opened on the top surface of the frame 1. The feeding groove 11 is located directly below the space between the two abutment rods 221. When the workpiece is processed, the two abutment rods 221 slide in a direction far away from each other, so that the workpiece falls on the bottom wall of the feeding groove 11, making it easy for the operator to pick up the processed workpiece.

[0054] Reference Figure 2 , Figure 4 and Figure 6Of the two abutment rods 221, a third rotary motor 226 is installed on one of them. The third rotary motor 226 is located above the third telescopic cylinder 225. The shaft of the third rotary motor 226 passes through the support block 224 and is fixedly connected to the end of one of the abutment rods 221. The shaft of the third rotary motor is rotatably connected to the support block 224. The workpiece is placed between the two abutment rods 221, and then both third telescopic cylinders 225 are activated simultaneously, causing the two abutment rods 221 to hold the workpiece in place. Then, the third rotary motor 226 is activated, driving one abutment rod 221 to rotate. Since the two abutment rods 221 hold the workpiece in place, the rotation of one abutment rod 221 drives the other abutment rod 221 to rotate synchronously with the workpiece, enabling the workpiece to rotate and allowing its circumferential direction to be polished. In this embodiment, the workpiece is a wooden handle. Each abutment 221 has multiple protrusions 2211 fixedly installed on the side of each abutment 221 that is close to each other. The multiple protrusions 2211 are arranged in a circumferential array along the abutment 221. The end of the multiple protrusions 2211 that is close to the workpiece is pointed, which makes it easy to insert into both ends of the workpiece and improves the fixing effect of the abutment 221 on the workpiece.

[0055] Reference Figure 1 and Figure 6 The feeding device 3 includes a storage component 31, a blocking mechanism 32, and a feeding component 33 for feeding workpieces to the polishing assembly 21. The storage component 31 is located on the side of the abutment 221 away from the abrasive belt 215. The storage component 31 is a storage plate, which is vertically arranged and includes a first plate 311 and a second plate 312. The first plate 311 is arranged opposite to each other, and the second plate 312 is detachably connected to both sides of the first plate 311 in the width direction. The distance between the two second plates 312 is adapted to the width of the workpiece, and the second plates 312 are located on the side of the first plate 311 that is close to each other. The blocking mechanism 32 is located below the storage component 31 and is used to lower a specified number of workpieces from the storage component 31 each time. In this embodiment, one workpiece is lowered from the storage component 31 each time. Workers place multiple workpieces from the top of the first plate 311 along the space between the two second plates 312. The two ends of the workpieces are located at the opposite ends of the first plate 311. The material blocking mechanism 32 causes one workpiece to descend at a time from the storage part 31. Then, the feeding assembly 33 transports the workpieces to the stop bar 221. This eliminates the need for workers to manually load the workpieces every time they are processed, saving labor, increasing automation, and improving loading efficiency.

[0056] Reference Figure 1 and Figure 6The first plate 311 is slidably configured, and can slide towards each other or away from each other. When the length of the workpiece changes, the distance between the two opposing first plates 311 is adjusted by sliding the first plates 311, which can easily accommodate workpieces of different lengths. A second sliding assembly 313 and a fixed base 314 are mounted on the frame 1. Each first plate 311 corresponds to a set of second sliding assemblies 313, and each set of second sliding assemblies 313 corresponds to a fixed base 314. The second sliding assemblies 313 are located on the fixed base 314.

[0057] Reference Figure 1 and Figure 6 The second sliding assembly 313 includes a fixed block 3131, a hand crank 3132, a hand crank 3133, a second screw 3134, and a second slider 3135. The fixed block 3131 is fixedly installed on the top surface of the fixed base 314. The fixed block 3131 is located at both ends of the second screw 3134 along its length. One end of the hand crank 3133 is fixedly connected to the hand crank 3132. One end of the second screw 3134 passes through the fixed block 3131 away from the first plate 311 and is fixedly connected to the side of the hand crank 3132 away from the hand crank 3133. The end of the second screw 3134 away from the hand crank 3132 passes through the second slider 3135 and is threadedly connected to the second slider 3135. The end of the second screw 3134 away from the hand crank 3132 is rotatably connected to the fixed block 3131 near the first plate 311. The second screw 3134 is rotatably connected to both corresponding fixed blocks 3131. The second sliding assembly 313 also includes fixing bars 3136, which are located on both sides of the second screw 3134 in the radial direction. A sliding space is formed between the two fixing bars 3136. The second slider 3135 is T-shaped. The two ends of the horizontal section of the second slider 3135 rest on the top surface of the corresponding fixing bars 3136, and the vertical section of the second slider 3135 is within the sliding space formed between the two fixing bars 3136. The second slider 3135 slides along the length of the fixing bars 3136 under the limiting action of the fixing bars 3136. A connecting plate 315 is fixedly connected to the side of the first plate 311 that is far apart from each other. The end of the connecting plate 315 that is far away from the first plate 311 is fixedly connected to the second slider 3135. By holding the hand crank 3133 and rotating the hand crank 3132, the second screw 3134 is rotated, which causes the second slider 3135 to slide, thereby causing the first plate 311 to slide.

[0058] Reference Figure 1 and Figure 6The first plate 311 has a first adjustment groove 3111, the length direction of the first adjustment groove 3111 is parallel to the width direction of the first plate 311, the end of the second plate 312 near the first plate 311 extends outwards in a direction away from each other, making the second plate 312 "L" shaped, the edge 3122 is connected to the edge 3121, the length of the first adjustment groove 3111 is greater than the distance between the two first adjustment bolts 3122, the screw of the first adjustment bolt 3122 passes through the edge 3121 and the first adjustment groove 3111 and is threaded to the first adjustment nut 3123, when the second plate 312 and the first plate 311 are fixed, the first adjustment nut 3123 and the side of the first plate 311 away from each other abut. When the width of the workpiece changes, the first adjusting nut 3123 and the first adjusting bolt 3122 are disengaged, and the first adjusting bolt 3122 is disengaged from the first adjusting slot 3111. The second plate 312 is then moved to a suitable position according to the width of the workpiece. The first adjusting bolt 3122 is then passed through the edge 3121 and the first adjusting slot 3111. The first adjusting nut 3123 is then rotated onto the first adjusting bolt 3122 and abuts against the first plate 311, thereby fixing the second plate 312 and the first plate 311.

[0059] Reference Figure 6The feeding assembly 33 includes a pneumatic gripper 331 and a support plate 332. A fourth telescopic cylinder 333, a guide rod 334, and a guide block 335 are fixedly installed on the top surface of the frame 1. The length directions of the guide rod 334 and the guide block 335 are perpendicular to the length direction of the abutment rod 221. A guide groove 3351 is opened on the side of the guide block 335 along its length direction. The guide groove 3351 penetrates the bottom surface of the guide block 335. The length of the guide rod 334 is greater than the length of the guide block 335. The guide rod 334 is located in the guide groove. Within the groove 3351, guide blocks 335 slide on guide rods 334. Guide blocks 335 are located at both ends of the support plate 332 along its length. The top surface of guide blocks 335 is fixedly connected to the bottom surface of the support plate 332, allowing the support plate 332 to slide. The piston rod of the fourth telescopic cylinder 333 extends or retracts towards or away from the abutment rod 221. The piston rod of the fourth telescopic cylinder 333 is fixedly connected to the side of the support plate 332 away from the abutment rod 221, allowing the support plate 332 to slide towards or away from the abutment rod 221. A fifth telescopic cylinder 336 is fixedly connected to the side of the support plate 332 near the abutment rod 221. Pneumatic grippers 331 are connected to the support plate 332 via the fifth telescopic cylinder 336. The piston rod of the fifth telescopic cylinder 336 is fixedly connected to the pneumatic grippers 331, and the fifth telescopic cylinder 336 drives the grippers to lift and lower. The pneumatic gripper 331 grips the workpiece by sliding and lifting, and then moves to the stop bar 221 by sliding and lifting, thus realizing the feeding process of the feeding component 33. The stop bar 221 first slides away from each other. When the workpiece moves to the stop bar 221, the stop bar 221 slides towards each other and stops the workpiece. Then the pneumatic gripper 331 moves back to its original position.

[0060] Refer to Figure 7 and Figure 8Each first plate 311 corresponds to a material-blocking mechanism 32. The material-blocking mechanism 32 includes a first baffle 321, a second baffle 322, a push rod 323, and a linkage assembly 324. The sidewall of the first baffle 321 and the side of the first plate 311 that are close to each other are detachably connected. The first baffle 321 is located below the second plate 312. The distance between the top surface of the first baffle 321 and the bottom surface of the second plate 312 is consistent with the total thickness of a specified number of workpieces falling. In this embodiment, the distance between the top surface of the first baffle 321 and the bottom surface of the second plate 312 is consistent with the thickness of a workpiece. An adjusting plate 3211 is fixedly connected to the bottom surface of the first baffle 321. A second adjusting groove 3212 is provided on the side of the first plate 311 that is close to each other, corresponding to the adjusting plate 3211. The second adjusting groove 3212 is vertically arranged. The adjusting plate 3211 is in the shape of a "7". The horizontal section of the adjusting plate 3211 is fixedly connected to the bottom surface of the first baffle 321. A second adjusting bolt 3213 is connected to the vertical section of the adjusting plate 3211. The second adjusting bolt 3213 passes through the vertical section of the adjusting plate 3211 and the second adjusting groove 3212 and is threadedly connected to a second adjusting nut 3214. When the first baffle 321 and the first plate 311 are fixed, the second adjusting nut 3214 abuts against the side of the first plate 311 that is far away from each other. When the thickness of the workpiece changes, the second adjusting nut 3214 and the second adjusting bolt 3213 are disengaged, and the second adjusting bolt 3213 is disengaged from the second adjusting slot 3212. The first baffle 321 is then moved to a suitable position according to the thickness of the workpiece. The second adjusting bolt 3213 is then passed through the adjusting plate 3211 and the second adjusting slot 3212. The second adjusting nut 3214 is then rotated onto the second adjusting bolt 3213 and abuts against the first plate 311, thereby fixing the first baffle 321 and the first plate 311.

[0061] Reference Figure 7 The top surface of the first baffle 321 has a clearance groove 3215. One end of the push rod 323 is connected to the support plate 332 via a linkage assembly 324, and the other end of the push rod 323 passes through the clearance groove 3215. The push rod 323 pushes a specified number of workpieces on the first baffle 321 toward the abutment rod 221. A support plate 3231 is fixedly connected to one end of the push rod 323 that passes through the clearance groove 3215. The support plate 3231 is located on the side of the first baffle 321 away from the abutment rod 221 and is used to support the workpieces behind the specified number of workpieces.

[0062] Reference Figure 7A limiting assembly 6 is connected to the first plate 311. The limiting assembly 6 includes a first limiting plate 61, a second limiting plate 62, and a third limiting plate 63. The first limiting plate 61 is fixedly connected to the side wall of the first plate 311 near the abutment 221. The second limiting plate 62 is fixedly connected to the side wall of the first limiting plate 61 near the abutment 221. The third limiting plate 63 is fixedly connected to the side wall of the first baffle 321 near the abutment 221. The surface of the first limiting plate 61 is parallel to the surface of the first plate 311. The surface of the second limiting plate 62 is parallel to the surface of the second plate 311. The surfaces of the body 312 are parallel, the surface of the third limiting plate 63 is coplanar with the surface of the second body 312, and the second baffle 322 is located between the second limiting plate 62 and the third limiting plate 63. The distance between the second limiting plate 62 and the third limiting plate 63 is set according to the actual situation so that it is greater than the width of the workpiece being processed. The first limiting plate 61, the second limiting plate 62 and the third limiting plate 63 work together to guide and limit the movement path of the workpiece, so that the workpiece can be quickly and accurately dropped from the first baffle 321 onto the second baffle 322 by the push rod 323.

[0063] Reference Figure 7 and Figure 9 The second baffle 322 is located below the first baffle 321. The length of the second baffle 322 is set to be relatively long, so that the workpiece can be stably positioned on the second baffle 322. The second baffle 322 is slidably arranged. A sixth telescopic cylinder 3221 for driving the second baffle 322 to slide is fixedly installed on the side of the first limiting plate 61 that is far away from each other. A mounting base 3222 is fixedly installed on the side of the first limiting plate 61 that is far away from each other. A first sliding groove 611 is opened on the surface of the first limiting plate 61, and the first sliding groove 611 penetrates the side of the first plate 311 near the first limiting plate 61. A second sliding groove 612 is opened on the surface of the first plate 311. 12 passes through the side of the first limiting plate 61 near the first plate 311. The first sliding groove 611 and the second sliding groove 612 are connected and located on the same plane. The second baffle 322 passes through the first sliding groove 611 and the second sliding groove 612 and is fixedly connected to the piston rod of the sixth telescopic cylinder 3221. The second baffle 322 can slide until the workpiece pushed by the push rod 323 is located on the second baffle 322. The second baffle 322 can also slide until it is no longer in contact with the workpiece pushed by the push rod 323. The pneumatic gripper 331 is located below the workpiece after passing the second baffle 322, which facilitates the pneumatic gripper 331 to rise directly to grip the workpiece and facilitates the support plate 332 to slide directly toward the abutment rod 221 after the pneumatic gripper 331 grips the workpiece.

[0064] The linkage component 324 drives the push rod 323 to slide within the clearance slot 3215. The push rod 323 pushes a specified number of workpieces on the first baffle 321 toward the direction close to the abutment rod 221. At this time, the support plate 3231 supports the workpieces behind the specified number of workpieces, reducing the impact of the workpieces behind the specified number of workpieces on the push rod 323 when it returns to its original position. After the specified number of workpieces fall onto the second baffle 322, the pneumatic gripper 331 is driven to move to the second baffle 322 to clamp the specified number of workpieces. Then, the second baffle 322 is slid to disengage from the workpieces pushed by the push rod 323. Then, the pneumatic gripper 331 moves the workpieces to the abutment rod 221 for polishing. This realizes that the material blocking mechanism 32 causes a specified number of workpieces to fall from the storage part 31 each time.

[0065] Reference Figure 6 and Figure 7 The linkage component 324 includes a first rack 3241, a first gear 3242, a second rack 3243, and a second gear 3244. The first rack 3241 is fixedly connected to the top surface of the support plate 332. The first gear 3242 meshes with the first rack 3241. The second gear 3244 and the first gear 3242 are coaxially arranged. A rotating shaft 3245 is rotatably connected to the top surface of the frame 1. Both the second gear 3244 and the first gear 3242 are fixedly connected to the rotating shaft 3245. Both the second gear 3244 and the first gear 3242 are connected by rotation. Shaft 3245 is rotatably connected to frame 1. The second rack 3243 and the second gear 3244 mesh. The first rack 3241 and the second rack 3243 are located on the same side, so that the first rack 3241 and the second rack 3243 move in the same direction. The push rod 323 is L-shaped. The vertical section of the push rod 323 passes through the clearance groove 3215. The horizontal section of the push rod 323 is fixedly connected to the second rack 3243. The top surface of the second gear 3244 is lower than the top surface of the second rack 3243, reducing the friction between the second gear 3244 and the push rod 323 during rotation.

[0066] Based on the distance the pneumatic gripper 331 moves from the second baffle 322 to the abutment 221 and the distance the push rod 323 needs to move to push the workpiece on the first baffle 321 onto the second baffle 322, the diameters of the first gear 3242 and the second gear 3244 are set. In this embodiment, the distance the push rod 323 needs to move to push the workpiece on the first baffle 321 onto the second baffle 322 is less than the distance the pneumatic gripper 331 moves from the second baffle 322 to the abutment 221. Therefore, the diameter of the second gear 3244 is set smaller than the diameter of the first gear 3242, so that the moving distance of the second rack 3243 is less than the moving distance of the first rack 3241. Ultimately, when the pneumatic gripper 331 moves from the second baffle 322 to the abutment 221, the push rod 323 can slide to push the workpiece on the first baffle 321 onto the second baffle 322.

[0067] When the support plate 332 slides towards the abutment rod 221, it drives the first gear 3242 to slide towards the abutment rod 221, causing the first gear 3242 to rotate, which in turn drives the rotating shaft 3245 to rotate, which in turn drives the second gear 3244 to rotate, causing the second rack 3243 to slide. Since the second rack 3243 and the first rack 3241 are on the same side, they move in the same direction, causing the push rod 323 to slide towards the abutment rod 221, thereby pushing the workpiece on the first baffle 321 to move onto the second baffle 322. At this time, the support plate 3231 will hold a specified number of workpieces. The pneumatic gripper 331 holds the workpiece behind it. After the pneumatic gripper 331 picks up the workpiece, it drives the second baffle 322 to slide away from the workpiece. After the workpiece is picked up, it drives the second baffle 322 to slide away again. When the support plate 332 slides away from the abutment rod 221, it drives the second gear 3244 to move in the opposite direction, drives the push rod 323 back to its original position, and drives the support plate 3231 to gradually detach from the workpieces behind the specified number of workpieces. At this time, under the limiting action of the second plate 312, the workpieces behind fall onto the first baffle 321. This process is repeated until the next workpiece falls onto the second baffle 322, so that the pneumatic gripper 331 picks up one workpiece at a time.

[0068] The implementation principle of a high-precision wooden handle curved surface polishing device according to an embodiment of this application is as follows: First, the first workpiece to be processed is manually placed on the pneumatic gripper 331 and gripped by the pneumatic gripper 331. Then, the fifth telescopic cylinder 336 is activated, driving the support plate 332 to slide towards the abutment rod 221, which in turn drives the first gear 3242 to slide towards the abutment rod 221, causing the first gear 3242 to rotate, which in turn drives the rotating shaft 3245 to rotate, which in turn drives the second gear 3244 to rotate, which in turn drives the second rack 3243 to slide towards the abutment rod 221, which in turn drives the push rod 323 to slide towards the abutment rod 221, thereby pushing the workpiece on the first baffle 321 to move onto the second baffle 322. At this time, the support plate 3231 holds the workpieces behind the specified number of workpieces. After the pneumatic gripper 331 grips the workpiece, the sixth telescopic cylinder 3221 drives the second baffle 322 to slide until it is separated from the workpiece. After the workpiece is gripped away, the second baffle 322 extends again to block the next workpiece.

[0069] After the pneumatic gripper 331 moves the workpiece to the stop bar 221, the pneumatic gripper 331 rises until the workpiece is at the same height as the stop bar 221. Then, the third telescopic cylinder 225 is activated to drive the stop bar 221 to hold the workpiece in place. Then, the first rotary motor 212 is activated to drive the sanding belt 215 to rotate. Then, the first telescopic cylinder 2161 is activated to drive the sanding belt 215 to slide. Then, the third rotary motor 226 is activated to drive the stop bar 221 to rotate, thereby rotating the workpiece and achieving polishing of the workpiece.

[0070] When the pneumatic gripper 331 returns to below the second baffle 322, it drives the push rod 323 and the linkage assembly 324 to return to their original positions, and the next workpiece falls onto the first baffle 321.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
