Description

Technical Field

[0001] The present invention relates to the technical field of hardware processing, and in particular to a drilling and grinding integrated combined processing device and method for hardware processing. Background Art

[0002] A drilling device is a mechanical device specifically designed to create holes in various materials. Its core function is to precisely drill a hole of the desired size and shape using a rotating drill bit, acting at a specific speed and pressure on the material being processed. This device is widely used in various fields, including construction, manufacturing, and maintenance, and is an indispensable tool in industrial production and daily life.

[0003] Patent application number CN118848560A discloses a drilling device for metal product processing, comprising a machine platform, an L-shaped frame disposed on top of the machine platform, a base disposed on the top of the machine platform in front of the frame, a cylinder disposed on the base, an electromagnet layer disposed on the inner sidewall of the cylinder, rectangular notches disposed on the top of each end of the base, a drive roller driven by a motor I disposed in the notch, and a driven roller disposed directly above the drive roller; a hydraulic rod disposed on the frame, wherein the hydraulic rod is connected to a drilling mechanism, the drilling mechanism comprising a box body accommodating a motor II, a sleeve disposed on the output shaft of the motor II, a fixing rod bolted to the sleeve, a drill bit disposed at the bottom end of the fixing rod below the sleeve, a grinding tube disposed on the fixing rod between the drill bit and the sleeve, and an annular grinding seat disposed at the top end of the grinding tube. The present invention can not only drill a hole in a product, but also grind the sidewalls of the hole.

[0004] In the drilling process, the formation of hole burrs (especially exit burrs) is closely related to the plastic deformation of the material. When the drill is about to penetrate the workpiece, the material undergoes plastic bending under the action of the axial cutting force, and the outer material curls along the drill bit edge to form burrs. Tough materials and thin plates are more prone to this problem due to their weak deformation resistance. Moreover, when cooling the plate during drilling, it is often the top of the plate that is affected, while the bottom of the plate is prone to deformation due to the increase in temperature.

[0018] The drilling and grinding method for hardware processing includes the following steps:

[0019] Step 1: A clamping device is provided on the top of the fixing frame, and the plate is fixed by the clamping device;

[0020] Step 2: Start the lifting device to descend, so that the drill rod at the bottom of the drilling equipment drills holes in the plate. At the same time, adjust the multiple fixing frames inside the rotating drum so that the mounting frames on the fixing frames are close to the drilling positions of the plate.

[0021] Step 3: During the drilling process, the flattening member inside the mounting frame is driven by the rotating drum and the transmission member to support and flatten the bottom of the plate;

[0022] Step 4: When the mounting frame contacts the bottom of the panel, the temperature of the panel rises, and the memory metal rod recovers through heat, so that the memory metal rod drives the cooling part through the traction part to automatically increase the spraying dosage, and the reciprocating movement of the flattening part continuously squeezes the cooling part for spraying.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. During the drilling process, the flattening parts inside the mounting frame are driven by the rotating drum and the transmission parts to support and flatten the bottom of the plate, so as to avoid the outer material curling along the drill bit edge to form burrs during the drilling process of the drill rod. The mounting frame and the flattening parts are rotated around the aperture of the plate through the action of the transmission parts. The flattening parts continuously push toward the middle of the aperture, pushing the plate at the outward-expanding aperture toward the middle, thereby ensuring support for the plate during drilling.

[0025] 2. When the contact frame is away from the center of the drill hole, it is located at the lower part of the circulation groove, reducing the outward expansion of the aperture caused by friction. The annular fixed frame in the rotating drum realizes circumferential support of the drilling site through the mounting frame. The flattening part performs radial reciprocating motion driven by the transmission part, effectively suppressing the curling of the material during drilling. When the contact frame moves toward the center of the drill hole, it is located at the upper part of the circulation groove and applies vertical pressure; when it moves away, it drops to the lower part to release the pressure, forming a periodic flattening action to suppress the outward expansion and deformation of the material.

[0026] 3. When the contact frame moves toward the center of the circle, the third gear meshes with the rack, forcing the torsion spring to store force and form elastic potential energy. At this time, the torsion force of the torsion spring will drive the connecting shaft to reverse. When the contact frame reaches the edge of the aperture, the toothless section of the rack releases the torsion spring instantly, driving the grinding wheel to reverse its speed, which can remove drilling burrs, grind the burrs that appear during drilling, and quickly process them around the aperture, avoiding the need to grind the bottom hole of the plate in the subsequent processing process.

[0027] 4. As the temperature of the plate rises, the memory metal rod recovers due to heat, causing the memory metal rod to drive the cooling part through the traction part to automatically increase the spray dosage, and the reciprocating movement of the flattening part continuously squeezes the cooling part for spraying. The memory metal rod recovers its spiral bending shape in response to temperature changes, and then pulls the traction part. The memory metal rod recovers its spiral deformation due to heat, and the spray volume is accurately controlled by the traction part, so that the coolant flow rate is positively correlated with the temperature gradient.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0043] like Figures 1 to 11 As shown, the drilling and grinding integrated processing device and method for hardware processing include the following embodiments: Example 1

[0044] The operating platform 1 includes a support arm 2 on the top, a lifting device 101 for lifting is provided on the outside of the support arm 2, a drilling device 201 is fixedly connected to the outside of the support arm 2, and a drill rod 202 is provided at the bottom of the drilling device 201.

[0045] A fixing frame 3 is fixedly connected to the top of the operating table 1. A through slot is provided on the top of the fixing frame 3. A rotating drum 4 is fixedly connected to the bottom of the fixing frame 3. A plurality of fixing frames 5 are arranged inside the rotating drum 4. The plurality of fixing frames 5 are arranged in a ring around the center of the fixing frame 3. A mounting frame 501 is fixedly connected to the top of each of the plurality of fixing frames 5. The mounting frame 501 extends into the through slot and contacts the bottom of the hardware. A flattening member is provided inside the mounting frame 501. A transmission member is provided between the fixing frame 5 and the rotating drum 4. When the rotating drum 4 rotates, the flattening member inside the fixing frame 5 is driven to move back and forth.

[0046] In specific implementation, during drilling processing, the formation of hole burrs, especially exit burrs, is closely related to the plastic deformation of the material. When the drill bit is about to penetrate the workpiece, the material undergoes plastic bending under the action of the axial cutting force, and the outer material curls along the drill bit edge band to form burrs. Tough materials and thin plates are more prone to this problem due to their weak deformation resistance. Therefore, this solution: by setting a clamping device on the top of the fixed frame 3, the clamping device can be set as a conventional hydraulic clamp, which will not be further elaborated here. The plate is fixed by the clamping device, and then the lifting device 101 is started to descend, so that the drill rod 202 at the bottom of the drilling equipment 201 is used to drill the plate. During drilling, the multiple fixed frames 5 inside the rotating drum 4 are adjusted so that the mounting frame 501 on the fixed frame 5 is close to the drilling position of the plate. During the drilling process, the rotating drum 4 and the transmission member drive the flattening member inside the mounting frame 501 to support and flatten the bottom of the plate to avoid the outer material curling along the drill bit edge band to form burrs during the process of drilling the plate with the drill rod 202. The mounting frame 501 and the flattening member are rotated around the aperture of the plate through the action of the transmission member, and the flattening member continuously pushes toward the middle of the aperture, pushing the plate at the outward-expanding aperture toward the middle to ensure support when drilling the plate.

[0047] In this embodiment, a rotating ring gear 401 is rotatably connected to the top of the rotating drum 4, and a plurality of first sliding grooves 400 are opened on the outside of the rotating ring gear 401. The tops of the plurality of fixed frames 5 are fixedly connected with sliding shafts 500, and the sliding shafts 500 extend into the inside of the first sliding groove 400 and are slidingly connected to the first sliding groove 400. The outside of the rotating ring gear 401 is meshedly connected with the first gear 402, and the first gear 402 is rotatably connected to the inside of the rotating drum 4. The inside of the rotating drum 4 is fixedly connected with a first motor, and the output shaft of the first motor is fixedly connected to the first gear 402. The bottom end of the rotating drum 4 is fixedly connected with a storage box 405. The outside of the rotating drum 4 is fixedly connected with a second ring gear 403, and the outside of the second ring gear 403 is meshedly connected with the second gear 404. The bottom of the fixed frame 3 is fixedly connected with a second motor, and the output shaft of the second motor is fixedly connected to the second gear 404. The bottom of the fixed frame 3 is fixedly connected with a bevel gear ring 301.

[0048] During specific implementation, when it is necessary to adjust the mounting bracket 501 to move to the vicinity of the plate drilling hole for support, by starting the first motor inside the rotating drum 4, the output shaft of the first motor drives the first gear 402 to rotate, and the first gear 402 drives the rotating ring gear 401 to rotate. At this time, the sliding shaft 500 on the top of the fixed frame 5 extends into the first slide groove 400, so that when the rotating ring gear 401 rotates, it drives the fixed frame 5 to move toward the center of the rotating ring gear 401, and adjusts according to different hole sizes. The mounting bracket 501 supports the vicinity of the drilling position, and the second motor drives the second gear 404 to rotate, the second gear 404 drives the second ring gear 403 to rotate, and the second ring gear 403 drives the rotating drum 4 to rotate, so that the mounting bracket 501 rotates in a circle around the plate drilling hole to support and protect the bottom of the plate.

[0049] Embodiment 2: The flattening member includes a contact frame 502, a first telescopic rod 503 is fixedly connected to the bottom of the contact frame 502, a moving block 504 is fixedly connected to the bottom of the first telescopic rod 503, guide plates 508 are provided on both sides of the contact frame 502, the guide plates 508 are fixedly connected to the mounting frame 501, and circulation grooves 5081 are provided on opposite sides of the two guide plates 508, and connecting shafts are fixedly connected on both sides of the contact frame 502, and the connecting shafts extend into the interior of the circulation groove 5081 and are slidably connected to the circulation groove 5081.

[0050] The transmission part includes a reciprocating screw 509, which passes through one end of the fixed frame 5 and is rotatably connected to the fixed frame 5, and the moving block 504 is threadedly connected to the reciprocating screw 509 through a ball nut pair. A second telescopic rod 505 is provided at one end of the fixed frame 5, and the second telescopic rod 505 passes through the fixed frame 5 and the rotating drum 4, and its two ends are rotatably connected to the fixed frame 5 and the rotating drum 4 respectively. The reciprocating screw 509 is fixedly connected to the second telescopic rod 505, and the other end of the second telescopic rod 505 is fixedly connected to a bevel gear 507, and the bevel gear 507 is meshed with the bevel gear ring 301.

[0051] In specific implementation, when the drum 4 rotates, since the two ends of the second telescopic rod 505 are respectively connected to the drum 4 and the fixed frame 5 for rotation, the bevel gear 507 at one end of the second telescopic rod 505 will mesh with the bevel gear ring 301, and the bevel gear 507 rotates. When the bevel gear 507 rotates, the reciprocating screw rod 509 is driven to rotate through the second telescopic rod 505, and the reciprocating screw rod 509 drives the moving block 504 to move back and forth. The moving block 504 drives the contact frame 502 to move back and forth horizontally in the middle of the guide plate 508 through the first telescopic rod 503, so that the top of the contact frame 502 continuously contacts the bottom of the plate. At the same time, a circulation groove 5081 is opened on the outside of the guide plate 508, and the contact frame 502 moves along the circulation groove 5081. The trajectory of the groove 5081 performs a circular motion. When the contact frame 502 moves toward the center of the drill hole, the contact frame 502 is at the upper part of the circulation groove 5081. When the contact frame 502 moves away from the center of the drill hole, the contact frame 502 is at the lower part of the circulation groove 5081, reducing the outward expansion of the aperture caused by friction. The annular fixed frame 5 in the rotating drum 4 realizes circumferential support of the drilling site through the mounting frame 501. The flattening part performs radial reciprocating motion driven by the transmission part, effectively suppressing the curling of the material during drilling. When the contact frame 502 moves toward the center of the drill hole, it is at the upper part of the circulation groove and applies vertical pressure; when it moves away, it drops to the lower part to release the pressure, forming a periodic flattening action to suppress the outward expansion and deformation of the material.

[0052] In this embodiment, the flattening part also includes a grinding wheel 6, which is arranged inside the contact frame 502, and both sides of the grinding wheel 6 are fixedly connected with a connecting shaft 601, which passes through the contact frame 502 and is rotatably connected to the contact frame 502. A torsion spring is provided on the connecting shaft 601, and the two ends of the torsion spring are respectively fixed to the connecting shaft 601 and the contact frame 502. One end of the connecting shaft 601 is fixedly connected to the third gear 602, and the outer side of the third gear 602 is meshed with a rack 603, and the rack 603 is fixedly connected to the mounting frame 501.

[0053] During specific implementation, a grinding wheel 6 is provided inside the contact frame 502. When the contact frame 502 moves toward the center of the drill hole, the third gear 602 on the connecting shaft 601 on both sides of the grinding wheel 6 engages with the rack 603. At this time, the torsion spring fixedly connected between the connecting shaft 601 and the contact frame 502 will store force. When the contact frame 502 moves toward the center of the circle, the third gear 602 engages with the rack 603 to force the torsion spring to store force, forming elastic potential energy storage. At this time, the torsion force of the torsion spring will drive the connecting shaft 601 to reverse. When the contact frame reaches the edge of the aperture, the toothless section of the rack 603 releases the torsion spring instantly, driving the grinding wheel 6 to reverse its speed, thereby removing drilling burrs, grinding the burrs that appear during drilling, and quickly processing around the aperture, avoiding the need to grind the bottom hole of the plate in the subsequent processing process.

[0054] Embodiment 3: A placement groove is provided on the top of each of the multiple mounting frames 501, and a memory metal rod 701 is provided inside the placement groove. A cooling component is provided inside the mounting frame 501, and a traction component is provided between the memory metal rod 701 and the cooling component. When the memory metal rod 701 is heated, it resets and contracts, and the traction component is adjusted to increase the spraying amount of the cooling component.

[0055] During specific implementation, the hole outlet area heats up due to friction, which intensifies the softening of the material. Bottom cooling can balance the temperature gradient and reduce the expansion of microcracks caused by thermal stress. If the bottom of the plate is directly sprayed for cooling, since the temperature change of the drilled hole does not rise directly, the large amount of spraying in the early stage will not be effective, so it is necessary to adjust according to the temperature change. Therefore, in this solution, when the mounting frame 501 contacts the bottom of the plate, the temperature of the plate rises and the memory metal rod 701 is heated and recovered, so that the memory metal rod 701 drives the cooling part to automatically increase the spraying dosage through the traction part, and continuously squeezes the cooling part for spraying through the reciprocating movement of the flattening part. The memory metal rod 701 restores the spiral bending shape to the temperature change, and then pulls the traction part. The memory metal rod 701 is heated and deformed spirally and restored. The spraying amount is accurately controlled by the traction part, so that the coolant flow rate is positively correlated with the temperature gradient.

[0056] In this embodiment, the cooling component includes an injection head 711 fixedly connected to one side of the sliding plate 702, a movable plate 703 is arranged between the two guide plates 508, a foldable capsule 707 is fixedly connected to one side of the movable plate 703, a push plate 708 is fixedly connected to one end of the foldable capsule 707, a third spring 710 is fixedly connected between the push plate 708 and the movable plate 703, the third spring 710 is sleeved on the outside of the foldable capsule 707, a liquid outlet pipe 709 is fixedly connected between the foldable capsule 707 and the injection head 711, and a liquid inlet pipe is fixedly connected between the third spring 710 and the storage box 405.

[0057] The traction part includes a fixed seat 704, which passes through the movable plate 703 and is slidingly connected, and a first spring 705 is sleeved on the outside of the fixed seat 704, and the two ends of the first spring 705 are respectively fixedly connected to the fixed seat 704 and the movable plate 703, one end of the memory metal rod 701 is fixedly connected to the sliding plate 702, and one end of the sliding plate 702 is fixedly connected to the traction rope 700, and the traction rope 700 passes through the mounting frame 501 and is fixedly connected to the movable plate 703.

[0058] In a specific implementation, when the cooling element is spraying, each time the contact frame 502 reciprocates, the push plate 708 between the guide plates 508 is squeezed, and the push plate 708 squeezes the foldable capsule 707, and the coolant inside the foldable capsule 707 is discharged through the liquid outlet pipe 709 and the spray head 711, thereby cooling the bottom of the plate. At the same time, the third spring 710 pushes the push plate 708 to automatically reset, so that the foldable capsule 707 opens to extract the coolant inside the storage box 405, thereby achieving the effect of automatic spraying, and is used in conjunction with the flattening element to reduce burrs and pore expansion.

[0059] At the same time, as the temperature changes caused by drilling, the memory metal rod 701 will bend after recovering from the rod shape. At this time, the memory metal rod 701 pulls the traction rope 700, and the traction rope 700 drives the movable plate 703 through the action of the guide wheel, so that the movable plate 703 moves on the fixed seat 704, thereby adjusting the extrusion distance of the contact frame 502 on the foldable capsule 707. When the movable plate 703 is close to the contact frame 502, the extrusion amount of the foldable capsule 707 inside the contact frame 502 will also increase. When the temperature drops, the memory metal rod 701 will reset, and the first spring 705 will pull the movable plate 703 to reset, automatically adjusting the dosage of each spray.

[0061] In specific implementation, when the drilling equipment 201 descends, the protective cover 9 will first contact the plate, and the protective cover 9 will block the waste chips when the drill rod 202 is drilling. When the drill rod 202 is drilling, and by starting the third motor to drive the fourth gear 905, the fourth gear 905 drives the meshing third gear ring 904, and the third gear ring 904 drives the protective cover 9 to rotate together through the second spring 903 and the collecting ring 907. The water pump in the water cylinder 900 inside the protective cover 9 delivers water to the multiple connecting pipes 1005, and sprays it out through the nozzle, and passes through the rotating plate 10. The electromagnet in the inner part continuously adjusts the magnetic force, pushing the sliding block 1003 away from the center of the rotating plate 10, and forming a barrier through the rotation of the protective cover 9, continuously pushing the waste chips away from the center of the protective cover 9, avoiding the waste chips from being squeezed and affecting the drilling of the drill rod 202. At the same time, when the sliding block 1003 moves to one end of the second slide groove 1002, it contacts the second switch 1006. At this time, the water pump and the electromagnet are powered off. At this time, the sliding block 1003 is reset under the action of the second switch 1006 to avoid bringing the waste chips back. The operation is repeated continuously to prevent the waste chips from flowing into the aperture and causing scratches.

[0066] Step 1: A clamping device is provided on the top of the fixing frame 3, and the plate is fixed by the clamping device;

[0067] Step 2: The lifting device 101 is then started to descend, so that the drill rod 202 at the bottom of the drilling equipment 201 drills holes in the plate. At the same time, the multiple fixing frames 5 inside the rotating drum 4 are adjusted so that the mounting brackets 501 on the fixing frames 5 are close to the drilling positions of the plate.

[0068] Step 3: During the drilling process, the rotating drum 4 drives the flattening member inside the mounting frame 501 through the transmission member to support and flatten the bottom of the plate;
