Description

Technical Field

[0001] This invention belongs to the field of deburring instrument technology, specifically relating to a high-precision deburring device for housings. Background Technology

[0002] Burrs refer to the residual shavings and extremely fine microscopic metal particles on the surface of metal parts. The more burrs there are, the lower the quality standard. Therefore, deburring is a very important step in the mechanical manufacturing process. Burrs have a great impact on the appearance and use of products. They should be avoided as much as possible during processing. If they cannot be avoided, there should be a subsequent deburring process.

[0003] The utility model patent with authorization announcement number CN218284969U discloses a deburring device for die castings, including a clamping part and a grinding part; a roller is rotatably installed between two ear plates, and a sanding belt for grinding burrs on die castings is installed between the two rollers; a dust filter screen for filtering dust is installed at the air holes on the baffle, and a fan is installed at each air hole on the baffle.

[0004] When in use, this deburring device can only deburr parts with a flat outer surface. It cannot grind and deburr parts with uneven surfaces, and the grinding surface is limited to a single type, making it unsuitable for complex parts. Furthermore, the device has low efficiency in absorbing debris, limiting its use and making it inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision deburring device for housings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-precision deburring device for housings, comprising:

[0008] The main housing has an outer shell installed on its upper outer side for protection and sealing. A work plate is provided at the top of the main housing, and a mounting platform is provided in the middle of the upper end of the work plate for mounting and fixing the workpiece to be processed. The workpiece to be processed is installed on the upper end of the mounting platform. An automatic robotic arm, which is an electric robotic arm in the prior art, is installed at the top of the inner part of the outer shell. A mounting box is provided at the lower end of the automatic robotic arm, and a main grinding wheel is provided at the lower end of the mounting box. The main grinding wheel is located above the mounting platform.

[0009] The main housing is equipped with a drive component 1, which drives the main grinding wheel to rotate, which is beneficial for grinding and removing burrs from the surface of the housing. The drive component 1 includes a drive motor and a drive rod. The drive motor is installed at the top of the main housing. The output end of the drive motor is connected to the drive rod. The lower end of the drive rod passes through the main housing and is connected to the main grinding wheel. The drive motor is started by an external controller, which drives the drive rod and the main grinding wheel to rotate, which can grind and remove burrs from the surface of the workpiece.

[0010] The main housing is also equipped with a second driving component. One end of the second driving component is connected to an auxiliary grinding wheel. The auxiliary grinding wheel is driven to rotate by the second driving component, which can grind the side edge or recessed part of the workpiece. It can extend and retract relative to the main grinding wheel, which is beneficial for removing burrs in special parts and improving deburring efficiency.

[0011] The upper end of the work plate is also provided with a side baffle. The side baffle is configured in multiple sets, and all sets of the side baffle are located on the outside of the mounting table. By providing the side baffle on the outside of the mounting table, it can play a protective role and prevent the grinding debris from flying around. Each side of the work plate is provided with a suction port, which can extract the fine debris generated by grinding. Combined with the airflow blown downward from the auxiliary box, it can further prevent the grinding debris from flying around.

[0012] Preferably, the second driving component includes a driver, a driven rod, and a linkage. The driver is also provided inside the main housing. The output end of the driver is connected to the driven rod. The driver can drive the driven rod to move telescopically, thereby facilitating the adjustment of the grinding depth of the auxiliary grinding wheel and facilitating the removal of burrs. The lower end of the driven rod is connected to the auxiliary grinding wheel, and the linkage is provided at the outer end of the driven rod. The driving motor drives the main rod and the main grinding wheel to rotate, and through the linkage, it can drive the driven rod to rotate, so that the driven rod drives the auxiliary grinding wheel to rotate, which is beneficial for grinding and deburring.

[0013] The actuator is a cylinder used to drive the driven rod to reciprocate. Alternatively, the actuator can be a telescopic rod or the like.

[0014] Preferably, the linkage includes a first fitting sleeve and a second fitting sleeve. The first fitting sleeve is provided at the outer end of the driving rod, and a gear tooth is fixedly connected to the outer end of the first fitting sleeve. The second fitting sleeve is provided at the outer end of the driven rod, and a gear tooth meshing with the gear tooth is provided at the outer end of the second fitting sleeve. When the driving rod rotates, it can drive the first fitting sleeve at its outer end to rotate. The gear teeth at the outer ends of the first and second fitting sleeves mesh, thereby causing the second fitting sleeve and the driven rod to rotate, which in turn drives the auxiliary grinding wheel to rotate.

[0015] Preferably, the length of the first mating sleeve is greater than the length of the second mating sleeve, so that while the driver drives the driven rod to extend and retract, the second gear tooth at the outer end of the second mating sleeve can slide along the tooth groove of the first gear tooth at the outer end of the first mating sleeve. That is, while the driven rod and the second mating sleeve are extending and retracting, the second gear tooth at the outer end of the second mating sleeve is always engaged with the first gear tooth at the outer end of the first mating sleeve, so as to prevent them from disengaging from each other.

[0016] The diameter of the first fitting sleeve is larger than that of the second fitting sleeve, which means that when the fitting sleeve rotates, the rotation speed of the second fitting sleeve is greater than that of the first fitting sleeve. This results in the second fitting sleeve driving the auxiliary grinding wheel to rotate faster than the main grinding wheel, thus improving the grinding effect of the auxiliary grinding wheel and enhancing the grinding quality.

[0017] Preferably, the linkage further includes a linkage groove, a first suction block, a return spring, and a second suction block. The outer end of the driven rod has multiple sets of linkage grooves, which are arranged in an array around the axis of the driven rod. The first suction block is installed inside each linkage groove. The second mating sleeve has an installation groove that mates with the linkage groove. The return spring is installed inside the installation groove, and one end of the return spring is connected to the second suction block.

[0018] The driven rod and the second mating sleeve are rotatably connected, which is beneficial when the auxiliary grinding wheel does not need to rotate, the first mating sleeve drives the second mating sleeve to rotate while the driven rod does not rotate.

[0019] The first attraction block is a magnetic block, and the second attraction block has an electromagnet inside that cooperates with the magnetic block. In use, when it is necessary to assist the rotation of the grinding wheel, the electromagnet is energized, causing it to overcome the tension of the return spring and attract the first attraction block. This attraction force moves one end of the second attraction block into the corresponding linkage groove, causing the second attraction block to simultaneously engage with both the linkage groove and the mounting groove. This secures the driven rod and the second mating sleeve, facilitating the mating sleeve's movement. The driven rod rotates, which in turn drives the main grinding wheel to rotate and the auxiliary grinding wheel to perform grinding. After the electromagnet is de-energized, the reset spring drives the second suction block back to the mounting slot, thereby releasing the linkage between the driven rod and the second fitting sleeve. This ensures that the rotation of the second fitting sleeve will not drive the driven rod to rotate, which is beneficial for the main grinding wheel to work independently. It should be noted that both the driven rod and the second fitting sleeve are made of materials that are not attracted by the electromagnet, thus preventing the electromagnet from attracting the driven rod and the second fitting sleeve after being energized, and avoiding affecting the movement of the second suction block.

[0020] The total length of the second suction block and the first suction block is greater than the length of the linkage groove. This means that when the second suction block extends into the linkage groove, it will not enter the linkage groove entirely. Instead, half of it will enter the linkage groove while the other half remains inside the mounting groove. This allows the second suction block to engage with both the linkage groove and the mounting groove simultaneously, thus fixing the driven rod and the second mating sleeve. This makes it easier for the second mating sleeve to drive the driven rod to rotate.

[0021] Preferably, one end of the suction block two is connected to a locking block, and the inside of the suction block one is provided with a locking groove that cooperates with the locking block, which is conducive to the suction block two locking into the inside of the linkage groove;

[0022] The end of the card block is provided with a smooth arc surface, which facilitates the sliding of the card block and the suction block into the corresponding linkage groove;

[0023] Both ends of the second suction block are provided with mating inclined surfaces, and the outer end of the linkage groove is provided with a guide inclined surface that mates with the mating inclined surfaces. The outer diameter of the linkage groove is larger than the inner diameter, that is, the opening is relatively large. Through the above-mentioned arrangement, the second suction block can be moved into the corresponding linkage groove more easily. With the help of the set locking block, the end of the second suction block can be further prevented from getting stuck between two adjacent sets of linkage grooves, thus preventing the second suction block from not entering the corresponding linkage groove.

[0024] Preferably, a limiting sleeve is fixedly connected to the lower end of the second fitting sleeve. The limiting sleeve is rotatably connected to the driven rod. A limiting block is fixedly connected inside the limiting sleeve. A limiting groove that mates with the limiting block is opened at the outer end of the driven rod. The limiting sleeve is rotatably connected to the driven rod through the limiting block, so that the limiting sleeve can limit the second fitting sleeve while preventing the second fitting sleeve from sliding up and down along the driven rod and preventing it from obstructing the rotation of the second fitting sleeve and the driven rod. A ball bearing is also provided at the outer end of the limiting block, which is beneficial for rolling along the inside of the limiting groove and reducing friction. (This is omitted in the figure.)

[0025] Preferably, auxiliary boxes are provided on both sides of the mounting box. The auxiliary boxes are equipped with rotating parts and fan blades. The rotating parts drive the fan blades to rotate, so that while deburring, the fan blades rotate and generate airflow, which blows away the burrs and prevents the burrs from accumulating on the surface of the workpiece and affecting the subsequent grinding effect. In addition, the rotation of the fan blades can also blow air from top to bottom, which can prevent the debris from flying upward.

[0026] The rotating component includes a driven gear, a connecting rod, a mounting rod, and a mounting sleeve. The mounting sleeve is installed inside the auxiliary box via the mounting rod. The connecting rod is rotatably connected inside the mounting sleeve. The lower end of the connecting rod is connected to the fan blade plate, and the upper end of the connecting rod is connected to the driven gear. The outer end of the driving rod is also provided with a driving gear that meshes with the driven gear. The outer side of the driving gear extends into the interior of the auxiliary box. In use, the driving rod drives the driving gear to rotate. The driving gear meshes with the driven gear and drives it to rotate, thereby causing the connecting rod to drive the fan blade plate to rotate. This is beneficial for grinding while blowing away the grinding debris, resulting in a better grinding effect.

[0027] The diameter of the driving gear is larger than that of the driven gear. Since the driving gear and the driven gear mesh and drive each other to rotate, the rotational speed of the driven gear driving the connecting rod and the fan blade is greater than the rotational speed of the driving gear driving the driving rod and the main grinding wheel. This makes it easier for the fan blade to rotate faster, generate more wind, and have a better blowing effect.

[0028] A connecting pipe is provided between the mounting box and the auxiliary box. The connecting pipe is located on the lower side of the auxiliary box, allowing the lower end of the auxiliary box to communicate with the interior of the mounting box. This allows the airflow generated by the rotation of the fan blades to enter the interior of the mounting box through the connecting pipe, increasing airflow inside the mounting box and providing ventilation and heat dissipation. This facilitates heat dissipation for the electrical components inside the mounting box. Furthermore, the airflow blown out through the connecting pipe can also be blown downwards through the through-hole at the bottom of the mounting box, preventing the accumulation of debris or dust inside the mounting box and avoiding any impact on the operation of its internal components, such as affecting the meshing and rotation of gears.

[0029] Preferably, the lower end of each side baffle is fixedly connected to a movable slider, and the upper end of the working plate is provided with a movable groove that cooperates with the movable slider. In use, the side baffle drives the movable slider to slide inside the movable groove and approach the mounting table and the workpiece to be processed, so as to play a role in shielding and protecting.

[0030] A downward pressure rod is slidably connected to the middle of the work plate. The upper end of the downward pressure rod passes through the mounting platform and extends above it. A rotating sleeve is rotatably connected to the lower end of the downward pressure rod. A base plate is provided inside the main housing. A support rod is installed on the upper end of the base plate. A fixed rod that cooperates with the rotating sleeve is connected to the upper end of the support rod. The rotating sleeve and the fixed rod are helically connected. The outer end of the rotating sleeve is connected to the movable slider through connecting parts. During installation, the workpiece to be processed is installed on the upper end of the mounting platform. The weight of the workpiece presses down the downward pressure rod, and the worker manually presses it down. Then, the workpiece is fixed, allowing the downward pressure rod to move downwards. The lower end of the downward pressure rod moves downwards. The rotating sleeve rotates and moves downwards, causing one end of the connecting piece to wrap around the outside of the rotating sleeve. The other end of the connecting piece moves the corresponding sliding block towards the mounting table, thereby moving the side baffles closer to the mounting table. This allows the multiple sets of side baffles to approach the workpiece when it is installed, facilitating the shielding of grinding debris. The combination of the pressing rod, rotating sleeve, and fixing rod ensures that the side baffles automatically approach the workpiece when it is installed and pressed down, reducing the use of electrical components, saving costs, and allowing the side baffles to effectively shield debris. It also allows the suction port of the side baffles to approach the workpiece and suck up the debris.

[0031] The connector is configured as a connecting belt, so that when the rotating sleeve rotates, one end of the connecting belt can be wound around its outer end, and the other end can exert a traction effect on the side baffle. Furthermore, the connector can also be configured as a hinge rod group composed of multiple sets of small hinge rods, that is, it can be wound around the outer end of the rotating sleeve and pull the opposite side baffle.

[0032] The bottom end of the movable slide is provided with a through slide, and the bottom end of the through slide penetrates the working plate, which is conducive to the passage of the connecting parts. This allows the connecting parts to move inside the movable slide and the through slide while the movable slider slides, without affecting the movement of the connecting parts. It also facilitates the falling of debris to the upper end of the base plate through the through slide.

[0033] One side of the movable slider is connected to an inclined block, and one side of the inclined block is provided with an inclined surface. When the movable slider moves inside the movable slide groove, it can drive the inclined block to move inside the movable slide groove, so that the inclined block can scrape off some of the debris accumulated inside the movable slide groove, thus avoiding affecting the movement of the movable slider inside the movable slide groove.

[0034] Each of the movable slides on the side away from the mounting platform is provided with an elastic reset band. One end of the elastic reset band is connected to the movable slider, so that when the workpiece is ground and removed from the mounting platform, the corresponding movable slider and side baffle can be reset, and the pressure rod can be reset.

[0035] The upper outer side of the rotating sleeve is connected to a limiting top plate, which limits the connecting parts that are wound around the outer end of the rotating sleeve, and facilitates the connecting parts to be wound around the outer end of the rotating sleeve.

[0036] The upper end of the work plate is also provided with multiple sets of through holes, which facilitates the falling of grinding debris to the upper part of the bottom plate inside the main box. The rotation of the fan blades also helps to blow the debris on the work plate and make it pass through the through holes. Furthermore, the airflow blown downward by the auxiliary box and the side baffles set on the outside of the mounting platform of the work plate to block the airflow, and the suction port of the side baffles to draw in the air, can form a relatively sealed space, which can prevent grinding debris from flying around.

[0037] Preferably, the side baffle has a connecting channel inside, and the connecting channel is connected to the suction port. A suction device is installed at the bottom of the main body. The suction device is located below the bottom plate. The suction device is a machine with suction function in the prior art, such as a vacuum cleaner. The bottom of the connecting channel is connected to a connecting pipe. The connecting pipe passes through the movable slider and is connected to the suction device. The connecting pipe passes through the working plate through the through groove, which also facilitates the movement of the connecting pipe by the side baffle and the movement of the connecting pipe inside the through groove. The connecting pipe is a telescopic pipe.

[0038] Each suction port is equipped with a filter screen to filter out large debris and prevent clogging of the suction port and connecting pipe.

[0039] The suction port is designed in the shape of a funnel, that is, the inner wall of the suction port is arc-shaped, which helps the debris filtered by the filter screen to slide down the arc-shaped inner wall of the suction port and avoids the debris from accumulating inside the suction port.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] This invention utilizes a main grinding wheel and an auxiliary grinding wheel that rotate simultaneously, enabling simultaneous grinding of the upper surface and sidewall edges of the workpiece. This results in higher grinding efficiency. The auxiliary grinding wheel can also extend and retract to grind recessed areas, facilitating the removal of burrs in specific locations and improving high-precision deburring efficiency. Furthermore, the auxiliary grinding wheel rotates at a higher speed, resulting in better grinding and facilitating fine grinding. Simultaneously, the grinding process drives the fan blades inside the auxiliary chamber to rotate, causing airflow from top to bottom. This helps to blow away grinding debris, further enhancing the grinding effect. Side baffles and suction ports on their sides can both shield and extract grinding debris, further preventing it from scattering. When the workpiece is installed, the side baffles can be simultaneously moved closer to it, reducing the need for electrical components and improving usability. Attached Figure Description

[0061] 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.

[0062] Example: Please refer to Figures 1-12 As shown, a high-precision deburring device for housings includes:

[0063] The main housing 10 has an outer shell 11 installed on its upper outer side for protection and sealing. A work plate 20 is provided at the top of the main housing 10. A mounting platform 21 is provided in the middle of the upper end of the work plate 20 for mounting and fixing the workpiece 22 to be processed. The workpiece 22 is installed on the upper end of the mounting platform 21. An automatic robotic arm 23 is installed at the top inside the outer shell 11. It is an electric robotic arm in the prior art. A mounting box 24 is provided at the lower end of the automatic robotic arm 23. A main grinding wheel 25 is provided at the lower end of the mounting box 24. The main grinding wheel 25 is located above the mounting platform 21.

[0064] The main housing 10 is equipped with a drive component 1, which drives the main grinding wheel 25 to rotate, which is beneficial for grinding and removing burrs from the surface of the housing. The drive component 1 includes a drive motor 241 and a drive rod 242. The drive motor 241 is installed at the top of the main housing 10. The output end of the drive motor 241 is connected to the drive rod 242. The lower end of the drive rod 242 passes through the main housing 10 and is connected to the main grinding wheel 25. The drive motor 241 is started by an external controller, which drives the drive rod 242 and the main grinding wheel 25 to rotate, which can grind and remove burrs from the surface of the workpiece 22.

[0065] The main housing 10 is also equipped with a second drive unit. One end of the second drive unit is connected to an auxiliary grinding wheel 26. The second drive unit drives the auxiliary grinding wheel 26 to rotate, which can grind the side edge or recessed part of the workpiece 22. It can move telescopically relative to the main grinding wheel 25, which is beneficial for removing burrs from special parts and improving deburring efficiency.

[0066] The upper end of the work plate 20 is also provided with a side baffle 30. The side baffle 30 is configured in multiple sets, and all sets of side baffle 30 are located on the outside of the mounting table 21. By providing the side baffle 30 on the outside of the mounting table 21, it can play a protective role and prevent the grinding debris from flying around. Each side of the work plate 20 is provided with a suction port 302, which can extract the fine debris generated by grinding. Combined with the airflow blown downward from the auxiliary box 248, it can further prevent the grinding debris from flying around.

[0067] refer to Figures 1-12As shown, the second driving component includes a driver 243, a driven rod 244, and a linkage. The driver 243 is also installed inside the main housing 10. The output end of the driver 243 is connected to the driven rod 244. The driver 243 can drive the driven rod 244 to move telescopically, thereby facilitating the adjustment of the grinding depth of the auxiliary grinding wheel 26 and facilitating the removal of burrs. The lower end of the driven rod 244 is connected to the auxiliary grinding wheel 26, and the outer end of the driven rod 244 is provided with a linkage. The drive motor 241 drives the driving rod 242 and the main grinding wheel 25 to rotate. At the same time, through the linkage, it can drive the driven rod 244 to rotate, so that the driven rod 244 drives the auxiliary grinding wheel 26 to rotate, which is beneficial for grinding and deburring.

[0068] The actuator 243 is a cylinder used to drive the driven rod 244 to reciprocate. Furthermore, the actuator 243 can also be a telescopic rod, etc.

[0069] refer to Figures 1-12 As shown, the linkage includes a first fitting sleeve 245 and a second fitting sleeve 246. The outer end of the driving rod 242 is provided with the first fitting sleeve 245, and the outer end of the first fitting sleeve 245 is fixedly connected with a gear tooth. The outer end of the driven rod 244 is provided with the second fitting sleeve 246, and the outer end of the second fitting sleeve 246 is provided with a gear tooth that meshes with the gear tooth. When the driving rod 242 rotates, it can drive the first fitting sleeve 245 at its outer end to rotate. The gear teeth at the outer ends of the first fitting sleeve 245 and the second fitting sleeve 246 engage, thereby causing the second fitting sleeve 246 and the driven rod 244 to rotate, which in turn drives the auxiliary grinding wheel 26 to rotate.

[0070] refer to Figures 1-12 As shown, the length of the first fitting sleeve 245 is greater than the length of the second fitting sleeve 246, so that while the driver 243 drives the driven rod 244 to move telescopically, the gear tooth 2 at the outer end of the second fitting sleeve 246 can slide along the tooth groove of the gear tooth 1 at the outer end of the first fitting sleeve 245. That is, while the driven rod 244 and the second fitting sleeve 246 are moving telescopically, the gear tooth 2 at the outer end of the second fitting sleeve 246 is always engaged with the gear tooth 1 at the outer end of the first fitting sleeve 245, so as to prevent them from disengaging from each other.

[0071] The diameter of the first fitting sleeve 245 is larger than the diameter of the second fitting sleeve 246. As a result, when rotating, the rotation speed of the second fitting sleeve 246 is greater than that of the first fitting sleeve 245. Consequently, the second fitting sleeve 246 drives the auxiliary grinding wheel 26 to rotate faster than the main grinding wheel 25. This results in a better grinding effect of the auxiliary grinding wheel 26, achieving high-precision deburring and improving the grinding quality.

[0072] refer to Figures 1-12As shown, the linkage also includes a linkage groove 2442, a first suction block 2443, a return spring 2444, and a second suction block 2445. Multiple sets of linkage grooves 2442 are provided at the outer end of the driven rod 244. The multiple sets of linkage grooves 2442 are arranged in an array around the axis of the driven rod 244. The first suction block 2443 is installed inside each linkage groove 2442. The second fitting sleeve 246 has an installation groove that mates with the linkage groove 2442. The return spring 2444 is installed inside the installation groove. One end of the return spring 2444 is connected to the second suction block 2445.

[0073] The driven rod 244 and the mating sleeve 246 are rotatably connected, which is beneficial when the auxiliary grinding wheel 26 does not need to rotate. The mating sleeve 245 drives the mating sleeve 246 to rotate without driving the driven rod 244 to rotate.

[0074] The first attraction block 2443 is a magnetic block, and the second attraction block 2445 has an electromagnet inside that cooperates with the magnetic block. In use, when it is necessary to assist the rotation of the grinding wheel 26, the electromagnet is energized, causing it to overcome the tension of the return spring 2444 and attract the first attraction block 2443. This attraction force moves one end of the second attraction block 2445 into the corresponding linkage groove 2442, causing it to simultaneously engage with both the linkage groove 2442 and the mounting groove. This fixes the driven rod 244 and the mating sleeve 246, facilitating the movement of the driven rod by the mating sleeve 246. Rotating rod 244 facilitates the rotation of the main grinding wheel 25 and also drives the auxiliary grinding wheel 26 to rotate and perform grinding. After the electromagnet is de-energized, the reset spring 2444 drives the second suction block 2445 back to the mounting slot, thereby releasing the linkage between the driven rod 244 and the second mating sleeve 246. This ensures that the rotation of the second mating sleeve 246 will not drive the driven rod 244 to rotate, which is beneficial for the main grinding wheel 25 to work independently. It should be noted that the driven rod 244 and the second mating sleeve 246 are both made of materials that are not attracted by the electromagnet, thus preventing the electromagnet from attracting the driven rod 244 and the second mating sleeve 246 after being energized, and avoiding affecting the movement of the second suction block 2445.

[0075] The total length of the second suction block 2445 and the first suction block 2443 is greater than the length of the linkage groove 2442. This means that when the second suction block 2445 extends into the linkage groove 2442, it will not enter the linkage groove 2442 entirely. Instead, half of it will enter the linkage groove 2442 while the other half remains inside the mounting groove. This allows the second suction block 2445 to engage with both the linkage groove 2442 and the mounting groove simultaneously, thus enabling the driven rod 244 and the mating sleeve 246 to be fixed. This facilitates the mating sleeve 246 in driving the driven rod 244 to rotate.

[0076] refer to Figures 1-12 As shown, one end of the suction block 2445 is connected to the locking block 2448, and the inside of the suction block 2443 is provided with a locking groove that cooperates with the locking block 2448, which is conducive to the suction block 2445 being locked inside the linkage groove 2442.

[0077] The end of the locking block 2448 is provided with a smooth arc surface, which facilitates the sliding of the locking block 2448 and the suction block 2445 into the interior of the corresponding linkage groove 2442;

[0078] Both ends of the suction block 2445 are provided with mating inclined surfaces 2447. The outer end of the linkage groove 2442 is provided with a guide inclined surface 2446 that mates with the mating inclined surfaces 2447. The outer diameter of the linkage groove 2442 is larger than the inner diameter, that is, the opening is relatively large. Through the above-mentioned arrangement, the suction block 2445 can move better into the interior of the corresponding linkage groove 2442. In addition, the locking block 2448 further prevents the end of the suction block 2445 from getting stuck between two adjacent sets of linkage grooves 2442, and prevents the suction block 2445 from not entering the interior of the corresponding linkage groove 2442.

[0079] refer to Figures 1-12 As shown, a limiting sleeve 247 is fixedly connected to the lower end of the second fitting sleeve 246. The limiting sleeve 247 is rotatably connected to the driven rod 244. A limiting block 2471 is fixedly connected inside the limiting sleeve 247. A limiting groove 2441 that mates with the limiting block 2471 is provided at the outer end of the driven rod 244. The limiting sleeve 247 is rotatably connected to the driven rod 244 through the limiting block 2471, so that the limiting sleeve 247 can limit the second fitting sleeve 246 while preventing the second fitting sleeve 246 from sliding up and down along the driven rod 244, and also preventing it from obstructing the rotation of the second fitting sleeve 246 and the driven rod 244. A ball is also provided at the outer end of the limiting block 2471, which is conducive to rolling along the inside of the limiting groove 2441 and reducing friction. This is omitted in the figure.

[0080] refer to Figures 1-12 As shown, auxiliary boxes 248 are provided on both sides of the mounting box 24. A rotating component is provided inside the auxiliary box 248, and the rotating component is connected to the fan blade 2485. The rotating component drives the fan blade 2485 to rotate, so that while grinding and deburring, the fan blade 2485 rotates and generates air force, which blows away the ground burrs and prevents the ground burrs from accumulating on the surface of the workpiece 22 and affecting the subsequent grinding effect. In addition, the rotation of the fan blade 2485 can also blow air from top to bottom, which can prevent the debris from flying upward.

[0081] The rotating components include a driven gear 2482, a connecting rod 2483, a mounting rod, and a mounting sleeve 2484. The mounting sleeve 2484 is mounted inside the auxiliary box 248 via the mounting rod. The connecting rod 2483 is rotatably connected inside the mounting sleeve 2484. The lower end of the connecting rod 2483 is connected to the fan blade 2485, and the upper end of the connecting rod 2483 is connected to the driven gear 2482. The outer end of the driving rod 242 is also provided with a driving gear 2481 that meshes with the driven gear 2482. The outer side of the driving gear 2481 extends into the interior of the auxiliary box 248. In use, the driving rod 242 drives the driving gear 2481 to rotate. The driving gear 2481 meshes with the driven gear 2482 and drives it to rotate, which in turn causes the connecting rod 2483 to drive the fan blade 2485 to rotate. This is beneficial for grinding and also blows away the grinding debris, resulting in a better grinding effect.

[0082] The diameter of the driving gear 2481 is larger than that of the driven gear 2482. Since the driving gear 2481 meshes with the driven gear 2482 and drives it to rotate, the rotational speed of the driven gear 2482 driving the connecting rod 2483 and the fan blade 2485 is greater than the rotational speed of the driving gear 2481 driving the driving rod 242 and the main grinding wheel 25. This is beneficial for the fan blade 2485 to rotate faster, generate greater wind power, and have a better blowing effect.

[0083] A connecting pipe 2486 connects the mounting box 24 and the auxiliary box 248. The connecting pipe 2486 is located on the lower side of the auxiliary box 248, allowing the lower end of the auxiliary box 248 to communicate with the interior of the mounting box 24. This allows the airflow generated by the rotation of the fan blade 2485 to enter the interior of the mounting box 24 through the connecting pipe 2486, increasing airflow inside the mounting box 24 and providing ventilation and heat dissipation. This facilitates heat dissipation for the electrical components inside the mounting box 24. Furthermore, the airflow from the connecting pipe 2486 can also be blown downwards through the through hole 201 at the bottom of the mounting box 24, preventing the accumulation of debris or dust inside the mounting box 24 and avoiding any impact on the operation of its internal components, such as affecting the meshing and rotation of gears.

[0084] refer to Figures 1-12 As shown, the lower end of the side baffle 30 is fixedly connected with a movable slider 34, and the upper end of the working plate 20 is provided with a movable groove 33 that cooperates with the movable slider 34. When in use, the side baffle 30 drives the movable slider 34 to slide inside the movable groove 33 and approach the mounting table 21 and the workpiece 22 to be processed, so as to play a role in shielding and protecting.

[0085] A downward pressing rod 35 is slidably connected to the middle of the work plate 20. The upper end of the downward pressing rod 35 passes through the mounting platform 21 and extends above the mounting platform 21. The lower end of the downward pressing rod 35 is rotatably connected to a rotating sleeve 36. A base plate 39 is provided inside the main housing 10. A support rod 391 is installed on the upper end of the base plate 39. A fixing rod 37 that cooperates with the rotating sleeve 36 is connected to the upper end of the support rod 391. The rotating sleeve 36 and the fixing rod 37 are spirally connected. The outer end of the rotating sleeve 36 is connected to the movable slider 34 through a connector 38. During installation, the workpiece 22 to be processed is installed on the upper end of the mounting platform 21. The weight of the workpiece 22 to be processed is used to press down the downward pressing rod 35, and the worker manually presses it down. Then the workpiece 22 is fixed, which allows the downward pressing rod 35 to move down. The lower end of the downward pressing rod 35 moves down and drives the rotating sleeve 36 to move. 6. Rotate and move downward. The rotating sleeve 36 rotates, which in turn drives one end of the connecting piece 38 to wrap around the outside of the rotating sleeve 36. The other end of the connecting piece 38 drives the corresponding moving slider 34 to move towards the mounting table 21, which in turn drives the side baffles 30 to approach the mounting table 21. This allows the multiple sets of side baffles 30 to approach the workpiece 22 when it is installed, which is convenient for blocking the debris generated during grinding. Through the cooperation of the pressing rod 35, the rotating sleeve 36 and the fixing rod 37, the side baffles 30 can be automatically driven to approach the workpiece 22 when it is installed and pressed down. This reduces the use of electrical components, saves costs, and helps the side baffles 30 to block debris. It also helps the suction port 302 of the side baffles 30 to approach the workpiece 22 and suck up the debris.

[0086] The connector 38 is configured as a connecting belt, so that when the rotating sleeve 36 rotates, one end of the connecting belt can be wound around its outer end, and the other end can exert a traction effect on the side baffle 30. Furthermore, the connector 38 can also be configured as a hinge rod group composed of multiple sets of small hinge rods, that is, it can be wound around the outer end of the rotating sleeve 36 and exert traction on the opposite side baffle 30.

[0087] The bottom end of the movable slide 33 is provided with a through slide 341, and the bottom end of the through slide 341 penetrates the working plate 20, which facilitates the passage of the connecting piece 38. This allows the movable slider 34 to slide while driving the connecting piece 38 to move inside the movable slide 33 and the through slide 341 without affecting the movement of the connecting piece 38. It also facilitates the falling of debris through the through slide 341 to the upper end of the base plate 39.

[0088] One side of the movable slider 34 is connected to an inclined block 342. One side of the inclined block 342 is provided with an inclined surface. While the movable slider 34 moves inside the movable slide 33, it can drive the inclined block 342 to move inside the movable slide 33, so that the inclined block 342 can scrape off some of the debris accumulated inside the movable slide 33, so as to avoid affecting the movement of the movable slider 34 inside the movable slide 33.

[0089] The movable slide 33 is equipped with an elastic reset band 301 on the side away from the mounting table 21. One end of the elastic reset band 301 is connected to the movable slider 34, so that when the workpiece 22 is ground and removed from the mounting table 21, the corresponding movable slider 34 and side baffle 30 can be reset, and the pressure rod 35 can be reset.

[0090] A limiting top plate 361 is connected to the outer side of the upper end of the rotating sleeve 36, which limits the connecting piece 38 that is wound around the outer end of the rotating sleeve 36, and facilitates the connecting piece 38 to be wound around the outer end of the rotating sleeve 36.

[0091] The upper end of the work plate 20 is also provided with multiple sets of through holes 201, which facilitates the falling of grinding debris to the upper end of the bottom plate 39 inside the main housing 10. The rotation of the fan blade 2485 also helps to blow the debris on the work plate 20 and make it pass through the through holes 201. Furthermore, the airflow blown downward by the auxiliary box 248, and the side baffle 30 provided on the outside of the mounting platform 21 of the work plate 20 to block the airflow, and the suction port 302 of the side baffle 30 to suck up the airflow, can form a relatively sealed space to prevent grinding debris from flying around.

[0092] refer to Figures 1-12 As shown, the side baffle 30 has a connecting channel 303 inside, and the connecting channel 303 is connected to the suction port 302. The suction device 32 is installed at the bottom of the main body 10. The suction device 32 is located below the bottom plate 39. The suction device 32 is a machine with suction function in the prior art, such as a vacuum cleaner. The bottom of the connecting channel 303 is connected to a connecting pipe 31. The connecting pipe 31 passes through the movable slider 34 and is connected to the suction device 32. It passes through the working plate 20 through the through groove 341, which also facilitates the side baffle 30 to drive the connecting pipe 31 to move. It is also beneficial for the connecting pipe 31 to move inside the through groove 341. The connecting pipe 31 is a telescopic pipe.

[0093] Each suction port 302 is equipped with a filter screen 304 to filter large debris and prevent clogging of the suction port 302 and the connecting pipe 31.

[0094] The suction port 302 is designed in the shape of a funnel, that is, the inner wall of the suction port 302 is arc-shaped, which makes it easier for the debris filtered by the filter screen 304 to slide down the arc-shaped inner wall of the suction port 302, and avoids the debris from accumulating inside the suction port 302.

[0095] This invention utilizes a main grinding wheel 25 and an auxiliary grinding wheel 26 that rotate simultaneously, enabling simultaneous grinding of the upper surface and sidewall edges of the workpiece 22. This results in higher grinding efficiency. The auxiliary grinding wheel 26 can also extend and retract to grind recessed areas, facilitating the removal of burrs in specific locations and improving deburring efficiency. Furthermore, the auxiliary grinding wheel 26 rotates at a higher speed, resulting in better grinding and facilitating fine grinding. Simultaneously, the grinding process drives the fan blades 2485 inside the auxiliary housing 248 to rotate, causing airflow from top to bottom. This helps to blow away grinding debris while grinding, further enhancing the grinding effect. The side baffles 30 and the suction port 302 on their sides can both shield and extract grinding debris, further preventing it from scattering. When the workpiece 22 is installed, the side baffles 30 can be moved closer to it simultaneously, reducing the need for electrical components and improving usability.

[0096] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
