Description

Technical Field

[0001] This application relates to the field of workpiece polishing technology, and more particularly to an automatic polishing device. Background Technology

[0002] Currently, the most common precision metal polishing process in China still relies on manual labor. Manual polishing wastes a lot of labor and causes high levels of fatigue. Workers in this job need to be replaced and retrained regularly before they can start working. Moreover, manual polishing cannot guarantee timeliness, accuracy, flatness, levelness, etc., and relies entirely on experience. Visual inspection is followed by spot checks for confirmation. If the work is not up to standard, batch rework is required, wasting a lot of manpower, material resources, and time. In addition, repeating the same action requires workers to endure high levels of fatigue, which can lead to physical fatigue and diseases due to non-ergonomic design. Summary of the Invention

[0003] This application provides an automatic polishing device. A consumable fixing component secures the polishing consumable to the moving end of a moving component, causing the moving component to drive the polishing consumable. A workpiece fixing component is installed at the telescopic end of a telescopic mechanism to fix the workpiece, allowing the telescopic mechanism to lift and lower the workpiece. This allows the workpiece to contact the polishing consumable for polishing or to separate and disassemble, thus achieving automatic polishing of the workpiece. This polishing device is easy to operate and highly efficient, solving the problems of current manual polishing of workpieces, which is time-consuming and laborious, and cannot meet the requirements for timeliness, precision, flatness, and levelness of polished parts.

[0004] This application provides an automatic polishing device, including a housing, a motion component, a telescopic mechanism, a consumable fixing component, a workpiece fixing component, and a control panel;

Two connecting plates are respectively connected to the moving parts of the two X-axis guide rails, and the two connecting plates are parallel. Two Y-axis guide rails are respectively fixed on the two connecting plates. Each Y-axis guide rail has two moving parts. The slide plate is fixed on the two Y-axis guide rails. The moving parts of the two Y-axis guide rails are connected to the slide plate. The middle of the slide plate has a blind hole facing the lower base plate. The consumable fixing assembly is fixed on the slide plate.

[0014] The motor is fixed to the side of the lower base plate opposite to the slide plate via a motor mount. The output end of the motor is connected to one end of the eccentric shaft, and the other end of the eccentric shaft passes through the transmission hole and is connected to the blind hole. The switch assembly is fixed to the housing. The control panel, the switch assembly, and the motor are electrically connected in sequence.

[0015] In one feasible implementation, the motion component further includes a shaft fixing member;

[0016] The shaft fixing member is fixed on the lower base plate and corresponds to the transmission hole. The shaft fixing member is sleeved on the eccentric shaft.

[0018] The fixing block is fixed to the lifting plate, and the fixing block is provided with a sliding groove. The length direction of the sliding groove is consistent with the extension direction of the telescopic mechanism. The telescopic cylinder is fixed to the inner wall of the top of the housing through the fixing seat, and the piston rod of the telescopic cylinder is slidably connected to the sliding groove.

[0019] In one feasible implementation, the automatic polishing equipment further includes a limiting component, which includes a mounting plate and multiple limiting posts;

[0020] The mounting plate is fixed inside the housing. The mounting plate is provided with clearance holes corresponding to the transmission holes. The bottom plate is fixed on the mounting plate. The first ends of the multiple limiting posts are all fixed to the outside of the mounting plate, and the second ends of the multiple limiting posts are all fixed to the top of the housing.

[0021] The pressure plate is provided with a plurality of first limiting holes corresponding to the limiting posts, and each of the plurality of first limiting holes is provided with a first sliding member.

[0024] In one feasible implementation, the bottom of the housing is provided with several brakeable casters, and the outer wall of the housing is provided with a folder.

[0025] This application provides an automatic polishing device that uses a consumable fixing component to fix the polishing consumable to the moving end of a moving component, allowing the moving component to drive the polishing consumable to move. A workpiece fixing component is set at the telescopic end of a telescopic mechanism to fix the workpiece, allowing the telescopic mechanism to lift and lower the workpiece, enabling the workpiece to contact and polish or separate from the polishing consumable, thereby achieving automatic polishing of the workpiece. This polishing device is easy to operate and highly efficient, solving the problems of current manual polishing of workpieces, which is time-consuming and laborious, and cannot meet the requirements for timeliness, precision, flatness, and levelness of polished parts.

[0026] This automatic polishing equipment has multiple second through holes set on the clamping plate, through which workpieces are inserted. Multiple elastic pressing components are set on the pressure plate, which fix multiple workpieces to the pressure plate, thereby polishing multiple workpieces at the same time and improving polishing efficiency.

[0027] During polishing, the telescopic mechanism extends, bringing the workpiece into contact with the polishing consumable. This causes the elastic pressing component to deform and store force, applying pressure to the workpiece towards the polishing consumable. As polishing progresses, the workpiece size gradually decreases, and the workpiece's locking end gradually moves towards the polishing consumable. This application controls the length of the telescopic mechanism so that when the workpiece's locking end engages with the clamping plate, and the workpiece just reaches the standard size, it cannot continue to move towards the polishing consumable, thus ensuring the dimensional accuracy of the workpiece after polishing.

Detailed Implementation

[0042] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0043] The specific structure of the automatic polishing equipment provided in this application will be described in detail below with reference to the accompanying drawings.

[0044] Reference Figure 1-6 As shown, this application embodiment provides an automatic polishing device, including a housing 100, a motion component 200, a telescopic mechanism 300, a consumable fixing component 400, a workpiece fixing component 500, and a control panel 800;

[0045] The housing 100 is composed of components such as the head housing, frame and sheet metal door. The control panel 800 is set on the housing 100. The control panel 800 includes a touch screen and several controllers. The control panel 800 controls the operation of this polishing equipment.

[0046] like Figure 1 As shown, both the motion component 200 and the telescopic mechanism 300 are disposed within the housing 100. The motion component 200 is disposed in the lower middle part of the housing 100, and the telescopic mechanism 300 is disposed in the upper part of the housing 100. The moving end of the motion component 200 and the telescopic end of the telescopic mechanism 300 are opposite to each other. The consumable fixing component 400 is fixed to the moving end of the motion component 200. The motion component 200 drives the consumable fixing component 400 and the polishing consumable to move synchronously. The workpiece fixing component 500 is fixed to the telescopic end of the telescopic mechanism 300. The workpiece fixing component 500 fixes the workpiece. The workpiece can move up and down under the drive of the telescopic mechanism 300. When the workpiece moves downward, it comes into contact with the polishing consumable in motion, and the workpiece can be polished.

[0047] The workpiece fixing assembly 500 includes a lifting plate 510, multiple connecting columns 520, multiple elastic pressing assemblies 530, connectors 540, clamping plates 550, and pressure plates 560.

[0048] The lifting plate 510 is a horizontal square plate. The lifting plate 510 is fixed to the telescopic end of the telescopic mechanism 300. The lifting plate 510 is connected to the pressure plate 560 through multiple connecting columns 520. The connecting columns 520 are columns with a certain height. There are four connecting columns 520, which are located at the four corners of the lifting plate 510.

[0049] like Figure 6 As shown, the pressure plate 560 is provided with a plurality of first through holes 561. The first through holes 561 are round holes. The twelve first through holes 561 are arranged in three rows and four columns. The plurality of first through holes 561 correspond one-to-one with a plurality of elastic pressing components 530. That is, there are twelve elastic pressing components 530. The twelve elastic pressing components 530 are all fixed on the pressure plate 560 and pass through the corresponding first through holes 561 respectively.

[0050] The pressure plate 560 is connected to the clamping plate 550 via the connector 540. The clamping plate 550 has a groove with twelve second through holes 551 inside. The second through holes 551 can be round holes. The polishing end of the workpiece passes through the second through hole 551. The snap-fit ​​part of the workpiece snaps into the clamping plate 550. For example, for a T-shaped workpiece, the bottom end of the vertical part of the T-shaped workpiece is the polishing surface, and the horizontal part of the T-shaped workpiece is the snap-fit ​​part. The vertical part of the T-shaped workpiece is inserted into the second through hole 551, and the horizontal part of the T-shaped workpiece is snapped into the clamping plate 550. Under the action of the telescopic mechanism, the elastic pressing component 530 presses down on the horizontal part of the T-shaped workpiece, so that the polishing surface of the T-shaped workpiece comes into contact with the polishing consumable in motion, and the polishing surface is polished. Of course, this application is also applicable to the polishing of L-shaped workpieces, flange rings, flanges and other tools.

[0051] This application provides an automatic polishing device that uses a consumable fixing component 400 to fix polishing consumables to the moving end of a moving component 200, causing the moving component 200 to drive the polishing consumables to move. A workpiece fixing component 500 is set at the telescopic end of a telescopic mechanism 300 to fix the workpiece, causing the telescopic mechanism 300 to drive the workpiece to rise and fall, allowing the workpiece to contact the polishing consumables for polishing or to separate and disassemble, thereby achieving automatic polishing of the workpiece. This polishing device is easy to operate and highly efficient, solving the problems of manual polishing of workpieces, which is time-consuming and laborious and cannot meet the requirements of timeliness, accuracy, flatness, and levelness of polished parts.

[0052] This automatic polishing equipment has multiple second through holes 551 on the clamping plate 550, through which workpieces are inserted. Multiple elastic pressing components 530 are set on the pressure plate 560, so that multiple workpieces are fixed to the pressure plate 560. This allows multiple workpieces to be polished at the same time, thereby improving polishing efficiency.

[0053] During polishing, the telescopic mechanism 300 extends, bringing the workpiece into contact with the polishing consumable. This causes the elastic pressing component 530 to deform and store force, applying pressure to the workpiece toward the polishing consumable. As polishing progresses, the workpiece size gradually decreases, and the workpiece's locking end gradually moves toward the polishing consumable. This application controls the length of the telescopic mechanism 300 so that when the workpiece's locking end engages with the clamping plate 550, the workpiece just reaches the standard size. At this point, the workpiece cannot continue to move toward the polishing consumable, thus ensuring the dimensional accuracy of the workpiece after polishing.

[0054] Reference Figure 3 and Figure 4 As shown, in some embodiments, the elastic pressing assembly 530 includes a flange disk 531, a spring cylinder 532, a spring 533, a locking block 534, a connecting shaft 535, and a workpiece pressing component 536.

[0055] The flange plate 531 is flange-shaped. The upper part of the flange plate 531 is fixed to the pressure plate 560, and the lower part of the flange plate 531 is inserted into the first through hole 561. The spring cylinder 532 is fixed on the upper surface of the flange plate 531. The spring 533 and the locking block 534 are both located inside the spring cylinder 532. The locking block 534 can be square or disc-shaped. The locking block 534 is locked to the flange plate 531. The spring 533 is vertically set, and its upper and lower ends are respectively in contact with the bottom inner wall of the spring cylinder 532 and the lower surface of the locking block 534. The spring 533 is always in a compressed state, applying a downward elastic force to the locking block 534, so that the locking block 534 and the flange plate 531 fit tightly together.

[0056] One end of the connecting shaft 535 is fixedly connected to the lower surface of the clamping block 534, and the other end of the connecting shaft 535 passes through the flange disc 531 and the first through hole 561 in sequence and is connected to the workpiece pressing member 536. When the workpiece is a flange, the workpiece pressing member 536 can be a cylindrical fixing member with the opening facing downward. The workpiece pressing member 536 is sleeved on the top of the flange. When the workpiece is a T-shaped plate, the workpiece pressing member 536 can be a square groove fixing member. The workpiece pressing member 536 is sleeved on the upper horizontal part of the T-shaped plate. Of course, the workpiece pressing member 536 can also be designed into other shapes according to the actual workpiece structure, which will not be described in detail again.

[0057] Reference Figure 3 As shown, in some embodiments, the workpiece fixing assembly 500 further includes a plurality of limiting blocks 570;

[0058] The limiting block 570 is a rectangular limiting block. The two limiting blocks 570 are respectively fixed at both ends of the pressure plate 560 facing the clamping plate 550. The pressure plate 560 and the clamping plate 550 clamp the limiting block 570, thereby avoiding damage to the workpiece pressing part 536 or the workpiece due to excessive pressure on the workpiece caused by the excessive length of the telescopic mechanism.

[0059] Reference Figure 7 As shown, in some embodiments, the automatic polishing equipment further includes a limiting component 600, which includes a mounting plate 610 and a plurality of limiting posts 620.

[0060] Mounting plate 610 is a horizontal plate that matches the size of housing 100. Mounting plate 610 is fixed inside housing 100. Mounting plate 610 is provided with clearance hole 611 corresponding to transmission hole 211. Lower base plate 210 is fixed on mounting plate 610.

[0061] The limiting post 620 is a vertical rod with a smooth outer wall. The first end of multiple limiting posts 620 is fixed to the outside of the mounting plate 610, and the second end of multiple limiting posts 620 is fixed to the top of the housing 100.

[0062] The pressure plate 560 is provided with a plurality of first limiting holes 562 corresponding to the limiting posts 620. Each of the plurality of first limiting holes 562 is provided with a first sliding member 563. Each of the plurality of first sliding members 563 is slidably connected to the corresponding limiting post 620. The clamping plate 550 is provided with a plurality of second limiting holes 552 corresponding to the limiting posts 620. Each of the plurality of second limiting holes 552 is provided with a second sliding member 553. Each of the plurality of second sliding members 553 is slidably connected to the corresponding limiting post 620. Both the first sliding member 563 and the second sliding member 553 can be high-temperature resistant silicone tubes. The pressure plate 560 and the clamping plate 550 are limited by the plurality of limiting posts 620, so that the pressure plate 560 and the clamping plate 550 can only move up and down.

[0063] In some embodiments, the limiting component 600 further includes a limiting plate 630;

[0064] The limiting plate 630 is fixed on the mounting plate 610. The limiting plate 630 is set vertically and its height can be adjusted according to the size of the workpiece. The limiting plate 630 is engaged with the clamping plate 550 so that the clamping plate 550 does not contact the consumable fixing component 400. During polishing, the bottom end of the workpiece rubs against the polishing consumable. When the top end of the workpiece is engaged with the clamping plate 550, although the workpiece is subjected to downward pressure from the elastic pressing component 530, the workpiece cannot continue to move downward. At this time, the size of the workpiece is fixed. By adjusting the height of the limiting plate 630, it is easy to ensure the standard size of workpieces of different sizes.

[0065] To facilitate the installation or disassembly of the workpiece, the connector 540 can be a connecting chain or a bolt. The bolt is inserted into the round hole on the pressure plate 560 and the clamping plate 550, so that the distance between the pressure plate 560 and the clamping plate 550 can be adjusted within a certain range.

[0066] Taking flange polishing as an example, before polishing, the telescopic mechanism 300 shortens, causing the pressure plate 560 to pull the clamping plate 550 upward through the connecting piece 540. At this time, the distance between the pressure plate 560 and the clamping plate 550 is at its maximum value. At this time, the workpiece pressing piece 536 and the clamping plate 550 have a certain distance, which allows the flange to be easily placed in the second through hole 551, so that the upper part of the flange is engaged with the clamping plate 550. During polishing, polishing consumables such as sandpaper are fixed by the consumable fixing component 400. The moving component 200 drives the consumable fixing component 400 and the polishing consumables to move. The telescopic mechanism 300 extends, and the pressure plate 560 and the clamping plate 550 move downward, and the bottom end of the flange... After contact with the polishing consumable, the flange, workpiece pressing part 536, connecting shaft 535 and clamping block 534 can no longer move downward, while clamping plate 550 and pressure plate 560 continue to move downward. The upper end of the flange separates from clamping plate 550. Then, workpiece pressing part 536 is sleeved on the upper end of the flange. Clamping plate 550 stops moving after clamping limit plate 630. Pressure plate 560 drives flange disc 531 and spring cylinder 532 to continue to move downward, so that the upper end of connecting shaft 535 extends into spring cylinder 532. Spring 533 is compressed and deformed, applying downward elastic force to the workpiece, so that the bottom end of the flange is tightly fitted with the polishing consumable, and the bottom end of the flange is polished.

[0067] As polishing progresses, the flange height gradually decreases, and the flange top gradually moves downward until it engages with the clamping plate 550 and can no longer move downward, thus ensuring the dimensional accuracy of the flange after polishing. The telescopic mechanism 300 shortens, and the pressure plate 560 pulls the clamping plate 550 upward through the connecting piece 540. The workpiece lower pressure piece 536 separates from the flange, making it easier to remove the flange and complete the flange polishing.

[0068] Reference Figure 8 and Figure 9 As shown, in some embodiments, the motion assembly 200 includes a lower base plate 210, two X-axis guide rails 220, two connecting plates 230, two Y-axis guide rails 240, a slide plate 250, a motor 260, an eccentric shaft 270, and a switch assembly 280.

[0069] The lower base plate 210 is a horizontally arranged square plate, which is fixed inside the housing 100. The lower base plate 210 is provided with a transmission hole 211, which is a round hole. Two X-axis guide rails 220 are respectively fixed on both sides of the lower base plate 210 in the Y-axis direction. Each of the two X-axis guide rails 220 has two moving parts. Two connecting plates 230 are respectively connected to the moving parts of the two X-axis guide rails 220, and the two connecting plates 230 are parallel. Two Y-axis guide rails 240 are respectively fixed on the two connecting plates 230. Each of the two Y-axis guide rails 240 has two moving parts. The slide plate 250 is fixed on the two Y-axis guide rails 240. The moving parts of the two Y-axis guide rails 240 are connected to the slide plate 250. The middle of the slide plate 250 is provided with a blind hole 251 facing the lower base plate 210. The consumable fixing assembly 400 is fixed on the slide plate 250.

[0070] The motor 260 is fixed to the side of the lower base plate 210 opposite to the slide plate 250 via a motor mount. The output end of the motor 260 is connected to one end of the eccentric shaft 270, and the other end of the eccentric shaft 270 passes through the transmission hole 211 and is connected to the blind hole 251. The switch assembly 280 is fixed on the housing 100. The control panel 800, the switch assembly 280 and the motor 260 are electrically connected in sequence. The motor 260 drives the slide plate 250, the consumable fixing assembly 400 and the polishing consumable to rotate around the output shaft of the motor 260, thereby causing the moving polishing consumable to polish the workpiece.

[0071] In some embodiments, the motion component 200 further includes a shaft retainer 290;

[0072] The shaft fixing member 290 is fixed on the lower base plate 210 and corresponds to the transmission hole 211. The shaft fixing member 290 is sleeved on the eccentric shaft 270. The inner wall of the shaft fixing member 290 is rotatably connected to the lower outer wall of the eccentric shaft 270, thereby facilitating the stable fixing of the eccentric shaft 270.

[0073] Reference Figure 10 As shown, in some embodiments, the automatic polishing equipment also includes an anti-drop mechanism 700, which can prevent the workpiece fixing assembly 500 from falling. The anti-drop mechanism 700 includes a fixing block 710, a telescopic cylinder 720, and a fixing seat 730.

[0074] The fixing block 710 is fixed on the lifting plate 510. The fixing block 710 is a vertically arranged fixing plate. The fixing block 710 is provided with a sliding groove 711. The length direction of the sliding groove 711 is consistent with the extension direction of the telescopic mechanism 300. The telescopic cylinder 720 is fixed to the inner wall of the top of the housing 100 through the fixing seat 730. The extension end of the telescopic cylinder 720 faces the sliding groove 711. The control panel 800 controls the extension and retraction of the telescopic cylinder 720.

[0075] Before polishing the workpiece, the control panel 800 controls the extension of the telescopic cylinder 720, so that the piston rod of the telescopic cylinder 720 is inserted into the slide groove 711. Then, when the workpiece is installed and polished, the telescopic mechanism drives the fixed block 710 to rise and fall. The piston rod of the telescopic cylinder 720 is slidably connected to the slide groove 711, and the piston rod is engaged with the upper or lower end of the slide groove 711, thereby preventing the workpiece fixing assembly 500 and the fixed workpiece from falling.

[0076] In some embodiments, the telescopic mechanism 300 includes a pressing cylinder 310;

[0077] The fixed end of the pressing cylinder 310 is fixed to the inner wall of the bottom end of the machine housing 100, and the telescopic end of the pressing cylinder 310 is connected to the workpiece fixing assembly 500. The control panel 800 controls the telescopic extension of the pressing cylinder 310.

[0078] Reference Figure 1 As shown, in some embodiments, the bottom of the housing 100 is provided with several brakeable casters 110, which facilitates the movement and fixation of the polishing equipment, and the outer wall of the housing 100 is provided with a folder 120, which facilitates the storage of files.
