Description

Technical Field

[0001] This invention belongs to the field of mechanical grinding technology, specifically a device for mechanically grinding and homogenizing the surface of a metal support. Background Technology

[0002] During the processing of metal brackets, oxide scale, welding slag and burrs will be generated on the surface, which need to be polished to meet the surface quality requirements. In the existing technology, gantry-type polishing equipment is usually used. The polishing head is moved in the horizontal and vertical directions by the sliding mechanism on the gantry to achieve the polishing operation on the surface of the metal bracket.

[0003] CN217143469U discloses a gantry-type workpiece grinding equipment, including a support platform, a working platform, a clamping device, a gantry frame, and a grinding device. The clamping device is located on the working platform and reciprocates along the Y-axis; the clamping device has at least one clamping mechanism; the gantry frame is located on the support platform; the grinding device is located on the gantry frame and above the clamping device, configured to reciprocate along the gantry frame in the X-axis direction and reciprocate along the Z-axis direction to grind the workpiece at the clamping device. The working platform has only one direction of movement, i.e., only a third drive mechanism is provided, which can reduce the thickness in the height direction and avoid the leakage of waste at the junction of the two interactive drive mechanisms in traditional systems. The combined arrangement of the gantry frame and the grinding device enables the grinding device to move in the X and Z axes, facilitating position adjustment.

[0004] This device can move the grinding head horizontally and vertically to grind the workpiece by means of a gantry frame. However, it cannot adjust the angle of the grinding head according to the curved shape of different parts of the metal bracket, resulting in poor grinding uniformity on the surface of irregular brackets. In addition, the debris generated during the grinding process cannot be effectively collected and quickly cleaned. Therefore, a mechanical grinding uniformization device for metal brackets is proposed. It can adjust the angle of the grinding head to adapt to different curved surfaces through a worm gear transmission mechanism, and can collect grinding debris and quickly disassemble and clean it through a dust collection mechanism.

The grinding mechanism includes a support platform, a first cylinder, and a support plate. The support platform is fixed to the drive end of the second electric slide, the first cylinder is fixed to one end of the support platform, and the support plate is fixed to the drive end of the first cylinder. The dust collection mechanism includes a mounting plate, a recycling box, and a mounting base. The mounting plate is fixed to the top of the workbench, the recycling box is located at one end of the mounting plate, and the mounting base is fixed to one end of the recycling box.

[0008] Preferably, the worm gear is rotatably connected to one end of the support plate, and the first motor and the second motor are symmetrically distributed about the central axis of the support plate.

[0009] Preferably, the inner wall of the adjusting frame is fitted to the outer wall of the worm gear, and the adjusting frame and the worm gear are rotatably connected.

[0010] Preferably, the transmission gear has several sets of teeth fixed to its exterior, and the worm and the transmission gear are meshed together.

[0011] Preferably, a first limiting plate is fixed to one end of the mounting base, a second limiting plate is slidably connected to one end of the mounting base, a slot is provided at one end of the mounting plate, a limiting rod is slidably connected inside the mounting plate, a return spring is installed outside the limiting rod, and a limiting block is fixed to one end of the limiting rod.

[0012] Preferably, four sets of mounting bases are provided, and the mounting bases are symmetrically distributed about the central axis of the recycling box. One end of the first limiting plate has an arc surface adapted to the limiting block, and one end of the second limiting plate has an arc surface adapted to the limiting block. The outer diameter of the second limiting plate is larger than the outer diameter of the first limiting plate.

[0013] Preferably, four sets of slots are provided, and the slots are symmetrically distributed about the central axis of the mounting plate. Two sets of limiting rods are provided, and the limiting rods are symmetrically distributed about the central axis of the slots.

[0014] Preferably, one end of the return spring is fixedly connected to the mounting plate, and the other end of the return spring is fixedly connected to the limiting rod. The return spring is used to press the limiting rod.

[0015] Preferably, a support frame is fixed to the top of the workbench, a second cylinder is fixed to the top of the support frame, a pressure block is fixed to the driving end of the second cylinder, and a funnel is fixed to one end of the support frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the combination of a support platform, a first cylinder, and a support plate, enables the device to achieve multi-dimensional angle adjustment of the grinding head and constant pressure grinding. This solves the core problems of existing gantry grinding equipment, such as its inability to adapt to the curved surfaces of irregularly shaped metal supports and poor grinding uniformity. The first cylinder drives the support plate to lift and lower to adjust the grinding height, and the first motor drives the worm gear to rotate. Through meshing with the transmission gear, the worm gear drives the support seat to rotate around the adjustment frame, realizing continuous adjustment of the grinding head angle. The second motor drives the adjustment frame to deflect in another direction to achieve bidirectional angle adjustment. The grinding angle can be adjusted in real time according to the curved surface shape of different parts of the metal support, ultimately achieving the effects of adapting to the complex curved surface of irregularly shaped supports, ensuring consistent grinding amount in all parts, and improving surface grinding uniformity.

[0017] This invention, through the coordinated arrangement of a mounting plate, a recycling box, and a mounting base, enables the device to achieve efficient collection of grinding debris and tool-free, rapid disassembly and cleaning of the dust collection component. This solves the core problems of existing grinding equipment, such as incomplete debris collection, cumbersome cleaning processes, and long downtime. The mounting plate provides stable support for the recycling box, which connects to the funnel via the mounting base. Grinding debris falls through the funnel into the recycling box for centralized storage. During disassembly, pressing the second limiting plate pushes the limiting block to compress the reset spring, disengaging it from the slot, allowing the recycling box to be removed. During installation, the reset spring automatically locks the box after insertion. Ultimately, this achieves the effects of improving debris collection efficiency, shortening cleaning and maintenance time, and ensuring continuous equipment operation. Attached Figure Description

[0023] like Figures 1 to 7As shown, the grinding mechanism 5 includes a support platform 501, a first cylinder 502, and a support plate 503. The support platform 501 is fixed to the drive end of the second electric slide table 4. The first cylinder 502 is fixed to one end of the support platform 501. The support plate 503 is fixed to the drive end of the first cylinder 502. A first motor 504 is fixed to the bottom end of the support plate 503.

Several sets of teeth are fixed on the outside of the transmission gear 508. The worm 505 and the transmission gear 508 are meshed together.

[0025] like Figures 1 to 7As shown, the dust collection mechanism 6 includes a mounting plate 601, a collection box 602, and a mounting base 603. The mounting plate 601 is fixed to the top of the workbench 1. The collection box 602 is located at one end of the mounting plate 601, and the mounting base 603 is fixed to one end of the collection box 602. A first limiting plate 604 is fixed to one end of the mounting base 603, and a second limiting plate 605 is slidably connected to one end of the mounting base 603. A slot 606 is provided at one end of the mounting plate 601. A limiting rod 607 is slidably connected inside the mounting plate 601. A return spring 608 is installed outside the limiting rod 607. A limiting block 609 is fixed to one end of the limiting rod 607. The mounting base 603 is provided with four sets of... The central axis of the recycling box 602 is symmetrically distributed. One end of the first limiting plate 604 has an arc surface that matches the limiting block 609. One end of the second limiting plate 605 has an arc surface that matches the limiting block 609. The outer diameter of the second limiting plate 605 is larger than the outer diameter of the first limiting plate 604. There are four sets of slots 606, which are symmetrically distributed about the central axis of the mounting plate 601. There are two sets of limiting rods 607, which are symmetrically distributed about the central axis of the slots 606. One end of the return spring 608 is fixedly connected to the mounting plate 601, and the other end of the return spring 608 is fixedly connected to the limiting rod 607. The return spring 608 is used to press the limiting rod 607.

[0026] The above scheme is adopted as follows: A mounting plate 601 is fixed to the top of the workbench 1 to provide a mounting base for the dust collection mechanism 6. A collection box 602 is set at one end of the mounting plate 601 to collect debris. A mounting base 603 is fixed to one end of the collection box 602 and has four sets of symmetrically distributed about the central axis of the collection box 602. A first limiting plate 604 is fixed to one end of the mounting base 603. A second limiting plate 605 is slidably connected to one end of the mounting base 603, and the outer diameter of the second limiting plate 605 is larger than the outer diameter of the first limiting plate 604. A slot 606 is opened at one end of the mounting plate 601 and has four sets of symmetrically distributed about the central axis of the mounting plate 601. A limiting rod 607 is slidably connected inside the mounting plate 601 and has two sets of symmetrically distributed about the central axis of the slot 606. One end of a return spring 608 is connected to the mounting plate. The other end of 601 is fixedly connected to the limiting rod 607 and is used to squeeze the limiting rod 607. The limiting block 609 is fixed to one end of the limiting rod 607. During installation, the recycling box 602 is inserted into the mounting plate 601. The first limiting plate 604 squeezes the two sets of limiting blocks 609. The limiting blocks 609 retract to allow the first limiting plate 604 to pass through. At this time, the limiting blocks 609 are reset by the return spring 608 to limit and fix the first limiting plate 604 and the recycling box 602. When removing, continue to press the recycling box 602. The second limiting plate 605 squeezes the two sets of limiting blocks 609. The limiting blocks 609 retract to allow the second limiting plate 605 to pass through. At this time, the second limiting plate 605 is in contact with the first limiting plate 604. Pull the recycling box 602 to remove it, realizing the quick disassembly and assembly of the dust collection mechanism and the debris cleaning effect.

[0027] The working principle and usage process of this invention are as follows: When in use, place the metal support to be polished on the worktable 1 with the polishing surface of the metal support facing upwards, start the second cylinder 8, the drive end of the second cylinder 8 extends and pushes the pressure block 9 downwards, the pressure block 9 contacts the surface of the metal support and presses the metal support tightly and fixes it on the worktable 1, preventing the metal support from shifting under force during the polishing process, the support frame 7 provides fixed support for the second cylinder 8, and keeps the pressing direction of the pressure block 9 on the metal support vertical.

[0028] Start the first electric slide 3. The first electric slide 3 moves horizontally along the crossbeam of the gantry 2, driving the second electric slide 4 and the grinding mechanism 5 mounted on it to move along the X-axis to above the area to be ground on the metal support. The gantry 2 provides horizontal guide support for the first electric slide 3. Start the second electric slide 4. The second electric slide 4 moves vertically, driving the grinding mechanism 5 to descend along the Z-axis, so that the grinding head 510 is close to the surface of the metal support.

[0029] The first cylinder 502 is activated, and the drive end of the first cylinder 502 extends to push the support plate 503 downward along the support platform 501. The support platform 501 is fixed to the drive end of the second electric slide 4 to provide the mounting base for the entire grinding mechanism 5. The support plate 503 drives the first motor 504, worm gear 505, second motor 506, adjustment frame 507, transmission gear 508, support seat 509 and grinding head 510 to feed downward as a whole, so that the grinding head 510 contacts the surface of the metal support. The contact pressure of the grinding head 510 on the surface of the metal support is adjusted by controlling the air intake of the first cylinder 502. When the pressure is constant, the grinding depth is uniform.

[0030] When the metal bracket is flat, the grinding head 510 grinds the surface in a vertical direction. The first electric slide 3 drives the grinding head 510 to move line by line along the X-axis. The first cylinder 502 controls the downward pressure of the grinding head 510 to keep it constant, so that the grinding head 510 moves evenly along the plane to complete the grinding operation.

[0031] When the part of the metal bracket to be ground is a curved or inclined surface, the first motor 504 is started. The drive end of the first motor 504 drives the worm gear 505 to rotate. The worm gear 505 is rotatably connected to one end of the support plate 503. The worm gear 505 meshes with the transmission gear 508. The rotation of the worm gear 505 drives the transmission gear 508 to rotate inside the adjusting frame 507. The transmission gear 508 drives the support seat 509 and the grinding head 510 to deflect, realizing the angle adjustment of the grinding head. The adjusting frame 507 drives the support seat 509 and the grinding head 510 to deflect synchronously, so that the axial direction of the grinding head 510 is consistent with the normal direction of the curved surface of the metal bracket. The grinding head 510 is in contact with the curved surface for grinding. The second motor 50 is then started. 6. The driving end of the second motor 506 drives the adjusting frame 507 to deflect in another direction, which cooperates with the deflection direction driven by the first motor 504 to realize the angle adjustment of the grinding head 510 in two directions. The first motor 504 and the second motor 506 are symmetrically distributed about the central axis of the support plate 503. The driving torque in both directions is evenly transmitted to the adjusting frame 507. The inner wall of the adjusting frame 507 is attached to the outer wall of the worm 505 and is rotatably connected to the worm 505, which guides and limits the deflection of the adjusting frame 507. The meshing of the worm 505 and the transmission gear 508 has a self-locking characteristic. When the first motor 504 stops rotating, the position of the adjusting frame 507 is locked, and the tilt angle of the grinding head 510 remains fixed to avoid the angle changing due to force during the grinding process.

[0032] When the metal bracket to be polished transitions from a flat surface to a curved surface, the first electric slide 3 drives the polishing mechanism 5 to move along the X-axis. At the same time, the first motor 504 drives the worm gear 505 to rotate according to the curvature change of the curved surface to adjust the tilt angle of the polishing head 510, so that the polishing head 510 tracks the change of the curved surface shape during the movement. The first cylinder 502 adjusts the downward pressure according to the undulation of the curved surface to keep the contact pressure between the polishing head 510 and the curved surface constant, so that the polishing depth of different parts is consistent, and uniform polishing of the surface of the metal bracket is achieved.

[0033] During the grinding process, the grinding head 510 grinds the surface of the metal support. The resulting debris and dust fall down into the dust collection mechanism 6 along the funnel 10. The funnel 10 is fixed to one end of the support frame 7 to collect and guide the debris. The debris enters the recycling box 602 through the funnel 10 for centralized collection. The mounting plate 601 is fixed to the top of the workbench 1 to provide support and connection base for the recycling box 602.

[0034] When debris accumulates inside the recycling box 602 and needs to be cleaned, continue pressing the recycling box 602 inward. The second limiting plate 605 on the mounting base 603 presses against the two sets of limiting blocks 609. The limiting blocks 609 drive the limiting rod 607 to slide along the inside of the mounting plate 601, compressing the return spring 608 and retracting. This causes the second limiting plate 605 to pass through the position of the limiting blocks 609. At this time, the second limiting plate 605 is in contact with the first limiting plate 604, and the limiting blocks 609 no longer obstruct the first limiting plate 604. Pulling the recycling box 602 outward will remove the recycling box 602 along with the mounting base 603 from the slot 606 of the mounting plate 601. Pour out the debris inside the recycling box 602. After cleaning, insert the recycling box 602 back into the mounting plate 601. When the first limiting plate 604 moves to the position of the limiting block 609 in the insertion direction, it squeezes the two sets of limiting blocks 609. The limiting blocks 609 drive the limiting rod 607 to slide and compress the reset spring 608, causing it to contract and allowing the first limiting plate 604 to pass through. After the first limiting plate 604 passes through, the reset spring 608 releases its elastic force and pushes the limiting rod 607 back to its original position. The limiting block 609 resets and locks behind the first limiting plate 604, limiting and fixing the first limiting plate 604 and the recycling box 602. The mounting base 603 is provided with four sets of symmetrically distributed about the central axis of the recycling box 602. The limiting rods 607 are provided with two sets of symmetrically distributed about the central axis of the slot 606. The locking force is evenly distributed around the mounting plate 601 to prevent the recycling box 602 from falling off due to the loosening of one side of the mounting base 603.
