Description

Technical Field

[0001] This invention relates to the field of wheel hub deburring technology, specifically a wheel hub deburring device. Background Technology

[0002] Wheel hubs are important load-bearing components of automobiles. Currently, most automobile wheels are made of aluminum alloy. After the aluminum alloy wheels are cast, due to the gaps in the mold and processing, many burrs and flashes are left on the surface of the aluminum alloy wheels. Therefore, the burrs need to be treated after the wheels are formed.

[0003] Currently, when workers manually remove burrs from wheel hubs, they need to move the hubs up and down. Because car wheel hubs are large and heavy, workers are prone to fatigue from moving them back and forth, which affects subsequent deburring operations. In addition, some workshop workers need to wear masks and gloves when removing burrs from wheel hubs, and the dust floating in the air is not treated, polluting the air environment and endangering the health of workers. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a wheel hub deburring device.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a deburring device for wheel hubs, including a worktable, a rotating structure on the worktable, an adjusting structure on the worktable, a feeding structure on one side of the worktable, a lifting structure on the feeding structure, a dust removal structure on the worktable, and a placement structure on the worktable;

[0006] The rotating structure includes fixed sleeves. Two fixed sleeves are slidably connected to both sides of the worktable. Rotating shafts are rotatably connected inside the fixed sleeves on both sides. Feed rollers are fixedly connected between two of the rotating shafts, and discharge rollers are fixedly connected between the other two rotating shafts. Ball bearings are rotatably connected inside the multiple rotating shafts, and the ball bearings are in rolling connection with the fixed sleeves.

[0007] Specifically, the adjustment structure includes a screw, a screw is rotatably connected to one side of the worktable via a bearing, a lead screw is rotatably connected to the other side of the worktable via a bearing, a threaded block is threadedly connected to the screw and the lead screw, the threaded block is slidably connected to the worktable, a fixing rod is fixedly connected to one side of the threaded block, and the fixing rod is fixedly connected to a fixing sleeve.

[0008] Specifically, a connecting rod is fixedly connected between the two threaded blocks, the connecting rod is slidably connected to the worktable, gears are fixedly connected to the bottom ends of the screw and lead screw, and a rack ring is slidably connected inside the worktable, with the gears meshing with the rack ring.

[0009] Specifically, the feeding structure includes a fixed frame, a fixed frame is provided on one side of the workbench, fixed plates are fixedly connected to both sides of the fixed frame, a feeding plate is installed at the center of the fixed frame, an mounting plate is fixedly connected to the bottom of the fixed frame, a slide rail is fixedly connected to the mounting plate, a slide rod is slidably connected to the slide rail, a support rod is slidably connected to one side of the slide rod, the top of the support rod is fixedly connected to the feeding plate, a limit plate is fixedly connected to the mounting plate, a rotating rod is rotatably connected to the limit plate, a sliding column is slidably connected to the rotating rod, the sliding column is slidably connected to the limit plate, and the sliding column is fixedly connected to the support rod.

[0010] Specifically, the lifting structure includes a cylinder, the cylinder is fixedly connected to the fixed frame, a horizontal plate is fixedly connected to the top of the cylinder, and abutment plates are fixedly connected to both sides of the horizontal plate. The abutment plates are movably connected to the fixed frame, and a rotating plate is rotatably connected to one end of the feeding plate. The abutment plates and the bottom ends of the rotating plates abut against each other.

[0011] Specifically, a guide plate is fixedly connected to the side of the workbench near the fixed frame. The guide plate is inclined, and protective plates are fixedly connected to both sides of the guide plate.

[0012] Specifically, an inclined plate is fixedly connected to the other side of the workbench, and the top of the inclined plate is set at an angle below the surface of the workbench.

[0013] Specifically, the dust removal structure includes a dust collection box, which is installed at the bottom of the workbench. A fan is fixedly connected to the workbench, and the fan is connected to the dust collection box through a pipe.

[0014] Specifically, a back plate is fixedly connected to the side of the workbench, and multiple air suction holes are arranged in a rectangular array on the back plate. The back plate is connected to a dust collection box through a pipe.

[0015] Specifically, the placement structure includes a placement plate, which is rotatably connected to one side of the workbench. The placement plate has a placement groove, and multiple protrusions are linearly distributed and fixedly connected to the side end of the placement plate. The workbench has multiple grooves, and the protrusions and grooves engage with each other.

[0016] The beneficial effects of this invention are:

[0017] (1) The deburring device for wheel hubs described in this invention has a rotating structure, an adjusting structure, and a placing structure on the worktable. The rotating structure facilitates rotating the wheel hub to grind the burrs on it. The adjusting structure facilitates fixing the wheel hub during feeding and removing it after grinding, avoiding manual handling of the wheel hub and reducing the labor intensity of workers. The placing structure can hold tools, allowing workers to use external tools to drive the adjusting structure. Specifically, by pulling the placing plate through the slot on the placing plate, the protrusion on the placing plate is no longer engaged with the groove on the worktable, opening the placing plate, taking out the tool in the placing slot, and rotating the screw on one side of the worktable with the tool. At the same time, the engagement of the gear and rack ring drives the lead screw to rotate, causing the screw and the threaded block on the lead screw to move downward. Then, the fixing rod drives the fixing sleeve to move downward, which in turn drives the feeding roller downward. When the surface of the feed roller is lower than the surface of the worktable, the hub falling onto the worktable can continue to roll forward until it comes into contact with the discharge roller and stops. Then, the screw is reversed, causing the screw and lead screw to rotate and drive the threaded block to move upward, thus moving the feed roller upward. When the feed roller and the hub come into contact, the feed roller and discharge roller can limit the hub. When the hub is turned, the feed roller and discharge roller can rotate through the ball bearings. By turning the hub, the burrs on the hub can be polished. After the burrs on the hub are removed, another screw on the worktable can be rotated by a tool. Through the meshing of the gear and rack ring, the screw rotates and drives the lead screw to rotate. This drives the discharge roller to move downward through the fixed rod. Then, the hub can continue to rotate and detach from the worktable without manual removal, reducing labor intensity. Then, the screw can be reversed, and the screw and lead screw can drive the threaded block and discharge roller to reset, which facilitates limiting the next hub that needs to be processed.

[0018] (2) The deburring device for wheel hubs described in this invention has a feeding structure on one side of the worktable, and a lifting structure on the feeding structure. The feeding structure and the lifting structure work together to facilitate the automatic feeding of new wheel hubs after grinding, avoiding manual back-and-forth movement of the wheel hubs and reducing labor intensity. That is, the wheel hubs to be processed can be gradually transported to the empty slots on the fixed plate and the feeding plate. When feeding is required, the motor on the fixed frame can be started. The motor rotation drives the rotating rod to rotate, and at the same time, the sliding column is limited by the limiting plate, so that the sliding column can slide in the rotating rod and slide along the rectangular slot on the limiting plate. When the rotating rod rotates and drives the sliding column to slide upward on one side of the rectangular slot in the limiting plate, the sliding column and the support rod are fixedly connected, which can drive the support rod to move upward along the sliding rod, and then drive the feeding plate fixed at the top of the support rod to move upward, which can lift the wheel hub fixed on the feeding plate. As the rotating rod continues to rotate, the sliding column can slide horizontally along the rectangular slot on the limiting plate. When the sliding column slides horizontally, the sliding connection between the support rod and the sliding rod is maintained. The sliding rod can slide horizontally on the slide rail, which in turn drives the support rod and the feeding plate to move horizontally. When the rotating rod drives the sliding column to slide downward along the other side of the rectangular groove, the support rod drives the feeding plate to slide downward, placing the hub on the feeding plate onto the fixed plate, allowing the hub to move forward and completing the feeding. Subsequently, the rotating rod rotates, causing the sliding column to slide horizontally, which in turn drives the support rod to move the feeding plate horizontally, allowing the feeding plate to reset. When the feeding plate rises again, it can lift and send the new hub forward. The hub sent forward by the feeding plate is located on the fixed plate. One end is in contact with the rotating plate on the fixed plate. When it needs to be polished, the cylinder on the fixed frame can be activated. The cylinder drives the horizontal plate to move downward, which in turn causes the contact plate on the horizontal plate to move downward. The contact plate no longer contacts the rotating plate and supports it. At this time, the rotating plate can rotate outward, and the hub that is in contact with the rotating plate also rolls forward from the fixed plate and falls onto the worktable. The hub is guided by the guide plate and the inclined plate on the worktable so that it continues to roll forward on the worktable until it is limited by the feed roller and the discharge roller.

[0019] (3) The deburring device for wheel hubs described in this invention has a dust removal structure on the workbench. The dust removal structure facilitates the collection and treatment of dust generated during grinding, preventing dust from escaping into the air and polluting the air environment, thus endangering the health of workers. Specifically, when processing the burrs on the wheel hub, the fan on the workbench is activated to suck the dust generated during grinding into the dust collection box, preventing the dust from escaping into the air. At the same time, the dust can be absorbed from the side through the suction holes on the back plate on one side of the workbench, preventing the dust from accumulating in the holes of the wheel hub and being unable to be absorbed from below.

[0033] Specifically, the adjustment structure 3 includes a screw 301. The screw 301 is rotatably connected to one side of the worktable 1 via a bearing, and a lead screw 302 is rotatably connected to the other side of the worktable 1 via a bearing. Threaded blocks 303 are threadedly connected to the screw 301 and the lead screw 302. The threaded blocks 303 are slidably connected to the worktable 1.

This facilitates the adjustment of the height of the feed roller 203 and the discharge roller 204, and facilitates the limiting of the wheel hub.

[0034] Specifically, the feeding structure 4 includes a fixed frame 401. A fixed frame 401 is provided on one side of the workbench 1. Fixed plates 402 are fixedly connected to both sides of the fixed frame 401. A feeding plate 403 is installed at the center of the fixed frame 401. An mounting plate 404 is fixedly connected to the bottom of the fixed frame 401. A slide rail 405 is fixedly connected to the mounting plate 404.

Fixed Connection; The lifting structure 5 includes a cylinder 501, which is fixedly connected to the fixed frame 401. A horizontal plate 502 is fixedly connected to the top of the cylinder 501, and abutment plates 503 are fixedly connected to both sides of the horizontal plate 502. The abutment plates 503 and the fixed frame 401 are movably connected. A rotating plate 504 is rotatably connected to one end of the feeding plate 403, and the bottom ends of the abutment plates 503 and the rotating plate 504 abut against each other. A guide plate 505 is fixedly connected to the side of the worktable 1 near the fixed frame 401. The guide plate 505 is inclined, and protective plates 506 are fixedly connected to both sides of the guide plate 505. An inclined plate 507 is fixedly connected to the other side of the worktable 1. The top of the inclined plate 507 is lower than the surface of the worktable 1 and is inclined. This facilitates the automatic feeding of the wheel hubs that need to be ground, eliminating the need for workers to move them and reducing labor intensity.

[0035] Specifically, the dust removal structure 6 includes a dust collection box 601, which is installed at the bottom of the workbench 1. A fan 602 is fixedly connected to the workbench 1, and the fan 602 is connected to the dust collection box 601 through a pipe. A back plate 603 is fixedly connected to the side of the workbench 1. Multiple suction holes 604 are arranged in a rectangular array on the back plate 603, and the back plate 603 is connected to the dust collection box 601 through a pipe. This facilitates the collection and treatment of dust generated during grinding, preventing dust from escaping into the air, polluting the air environment, and endangering the health of workers.

[0036] Specifically, the placement structure 7 includes a placement plate 701, which is rotatably connected to one side of the workbench 1. The placement plate 701 is provided with a placement groove 702, and multiple protrusions 703 are linearly distributed and fixedly connected to the side end of the placement plate 701. The workbench 1 is provided with multiple grooves 704, and the protrusions 703 and grooves 704 engage with each other; thereby placing tools and facilitating workers to rotate the screw 301 using external tools.

[0037] In use, the wheel hub to be processed is first transported to the empty slots on the fixed plate 402 and the feeding plate 403. When feeding is required, the motor on the fixed frame 401 is started, which drives the rotating rod 409 to rotate. At the same time, the sliding column 410 is limited by the limiting plate 408, allowing the sliding column 410 to slide within the rotating rod 409 and along the rectangular slot on the limiting plate 408. When the rotating rod 409 rotates and drives the sliding column 410 to slide upward on one side of the rectangular slot in the limiting plate 408, the sliding column 410 is fixedly connected to the support rod 407, which drives the support rod 407 to move upward along the sliding rod 406. This, in turn, drives the feeding plate 403, which is fixed to the top of the support rod 407, to move upward. The hub fixed on the feeding plate 403 can be lifted. As the rotating rod 409 continues to rotate, the sliding column 410 can slide horizontally along the rectangular groove on the limiting plate 408. When the sliding column 410 slides horizontally, the sliding rod 406 can be driven to slide horizontally on the slide rail 405 through the sliding connection of the support rod 407 and the sliding rod 406. This, in turn, drives the support rod 407 and the feeding plate 403 to move horizontally. When the rotating rod 409 drives the sliding column 410 to slide downward along the other side of the rectangular groove, the support rod 407 drives the feeding plate 403 to slide downward, placing the hub on the feeding plate 403 onto the fixed plate 402, allowing the hub to move forward and completing the feeding. Subsequently, the rotating rod 409 rotates, driving the sliding column 410 to slide horizontally, causing the support rod 407 to move horizontally. The feeding plate 403 moves horizontally to reset. When the feeding plate 403 rises again, a new hub can be lifted and fed forward. The hub fed forward by the feeding plate 403 is located at one end of the fixed plate 402 and abuts against the rotating plate 504 on the fixed plate 402. When grinding is required, the cylinder 501 on the fixed frame 401 can be activated, which drives the horizontal plate 502 to move downward, thereby causing the abutting plate 503 on the horizontal plate 502 to move downward. The abutting plate 503 no longer abuts against the rotating plate 504 and supports the rotating plate 504. At this time, the rotating plate 504 can rotate outward, and the hub abutting against the rotating plate 504 also rolls forward from the fixed plate 402 and falls onto the guide plate 505 on the worktable 1. Guided by the protective plate 506, it continues to roll forward. When the cylinder 501 works and drives the horizontal plate 502 to move downward, the placement plate 701 can be pulled through the slot on the placement plate 701, so that the protrusion 703 on the placement plate 701 is no longer engaged with the groove 704 on the worktable 1. The placement plate 701 is opened, and the tool in the placement groove 702 is taken out. The screw 301 on one side of the worktable 1 is rotated by the tool. At the same time, the lead screw 302 is rotated through the meshing of the gear 306 and the rack ring 307, so that the screw 301 and the threaded block 303 on the lead screw 302 move downward. Then, the fixed sleeve 201 is moved downward through the fixed rod 304, which in turn drives the feed roller 203 to move downward. When the surface of the feed roller 203 is lower than the surface of the worktable 1,The hub, which rolls forward past the guide plate 505 and the protective plate 506, can continue forward past the feed roller 203 and stop when it comes into contact with the discharge roller 204. Then, the screw 301 is reversed, causing the screw 301 and the lead screw 302 to rotate and drive the threaded block 303 to move upward, thus moving the feed roller 203 upward. When the feed roller 203 comes into contact with the hub, the feed roller 203 and the discharge roller 204 can limit the hub. When the hub is turned, the feed roller 203 and the discharge roller 204 can rotate through the ball bearings 205. By turning the hub, the burrs on the hub can be ground. When the burrs on the hub are being processed, the fan 602 on the worktable 1 is started to suck the dust generated by grinding into the dust collection box 601 to prevent the dust from escaping into the air. At the same time, the dust is also drawn through the side of the worktable 1. The suction holes 604 on the back plate 603 can absorb dust from the side, preventing dust from accumulating in the holes of the hub and making it impossible to absorb from below. After the burrs on the hub are removed, another screw 301 on the worktable 1 can be rotated using a tool. The gear 306 and rack ring 307 mesh together, causing the lead screw 302 to rotate as the screw 301 rotates. This, in turn, causes the discharge roller 204 to move downwards via the fixed rod 304. The hub can then continue to rotate, rolling forward along the inclined plate 507 on the worktable 1 and detaching from it without manual removal, reducing labor intensity. The screw 301 can then be reversed, causing the threaded block 303 and discharge roller 204 to reset via the screw 301 and lead screw 302, facilitating the positioning of the next hub to be processed.
