Description

Technical Field

[0001] This utility model belongs to the field of metal rack processing technology, and specifically relates to a drilling device for metal rack processing. Background Technology

[0002] Metal rack processing refers to the process of using metal materials such as steel and aluminum alloys as raw materials, and processing metal sheets or profiles into rack products with specific structures and functions through processes such as cutting, stamping, bending, welding, and grinding. This processing requires precise control of the connection hole positions of the metal rack according to the design drawings to facilitate the assembly of the metal rack, ultimately forming a metal frame for carrying and storing materials in scenarios such as warehousing, logistics, and production. Its processing quality directly affects the load-bearing capacity, stability, and service life of the rack.

[0003] In the existing metal rack processing drilling device, the metal rack is first fixed on the worktable, and then the drilling position is precisely calibrated. The drill bit rotates at high speed under the drive of the power system and is pushed downward by the feed mechanism to perform drilling operations on the metal rack. After drilling is completed, the drill bit returns to its original position, completing the drilling process of the metal rack.

[0004] However, in the processing of existing metal racks, since the raw materials for metal racks are mostly long rectangular or cylindrical, and multiple racks need to be connected to the surface of a single rack during assembly, it is necessary to drill holes on multiple sides of the long rectangular or cylindrical metal rack to ensure the subsequent assembly of the metal racks. However, when existing drilling devices perform multi-sided drilling, the metal rack must first be fixed, and after drilling is completed, the metal rack must be loosened and switched to another side, and then repositioned before drilling can continue. The operation steps are relatively cumbersome and the practicality is poor. Utility Model Content

[0005] In view of the problem that when processing multi-faceted holes in related technologies, it is necessary to loosen the metal rack, switch to the other side, reposition it, and then continue drilling, which is a cumbersome operation and has poor practicality, this utility model proposes a drilling device for processing metal racks to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a drilling device for processing metal racks, including a frame, a pneumatic clamping mechanism is provided on the surface of the frame, a rotation adjustment mechanism is provided inside the pneumatic clamping mechanism, two support clamping mechanisms are provided on both sides of the frame, a drive feeding mechanism is provided inside the support clamping mechanism, and a drilling mechanism is provided on the surface of the frame. The pneumatic clamping mechanism is used to clamp and fix the metal rack. The clamping end of the pneumatic clamping mechanism is driven to rotate by the rotating end of the rotary adjustment mechanism, so that the clamping end of the pneumatic clamping mechanism drives the metal rack to rotate.

[0007] Furthermore, the pneumatic clamping mechanism includes a placement plate, which is fixedly mounted on the surface of the frame. A drive ring is rotatably connected inside the placement plate, and a clamping plate is slidably connected inside the drive ring. A piston is fixedly connected to one end of the clamping plate. An air passage is provided inside the drive ring, which communicates with and compresses the piston. An air inlet pipe is fixedly connected to one side of the placement plate, and one end of the air inlet pipe communicates with the air passage on the side of the drive ring. A ball bearing is movably connected to one end of the clamping plate.

[0008] Furthermore, the rotation adjustment mechanism includes a drive gear, which is rotatably connected inside the placement plate. The surface of the drive ring is provided with a toothed groove, which meshes with the drive gear. One end of the placement plate is fixedly mounted with a motor, and the output shaft of the motor is fixedly connected to the drive gear.

[0009] Furthermore, an ash storage trough is provided in the middle of the placement plate.

[0010] Furthermore, the support and clamping mechanism includes a mounting base, which is fixedly connected inside the frame. A bidirectional screw is rotatably connected inside the mounting base, and a movable frame is threadedly connected to the surface of the bidirectional screw. An arc-shaped roller is rotatably connected inside the movable frame. A second motor is fixedly connected to one side of the mounting base, and the output shaft of the second motor is fixedly connected to the bidirectional screw.

[0011] Furthermore, the driving feeding mechanism includes a driving rod, which is rotatably connected inside the mounting base. A bevel gear one is splined on the surface of the driving rod. The bevel gear one is rotatably connected inside the movable frame. A bevel gear two meshes on the surface of the bevel gear one. The bevel gear two is fixedly connected to one end of the arc-shaped roller. A rubber strip is fixedly connected to the surface of the arc-shaped roller. A motor three is fixedly connected to one side of the mounting base. The output shaft of the motor three is fixedly connected to the driving rod.

[0012] Furthermore, the drilling mechanism includes a fixed frame, which is fixedly connected to the surface of the machine frame. A motor is fixedly connected to one end of the fixed frame, and a lead screw is fixedly connected to the output shaft of the motor. The lead screw is rotatably connected inside the fixed frame, and a lifting plate is threadedly connected to the surface of the lead screw. The drilling machine body is fixedly installed on the surface of the lifting plate.

[0013] This utility model has the following beneficial effects: This invention uses a pneumatic clamping mechanism to clamp and fix a metal rack. The rotating end of the rotary adjustment mechanism drives the clamping end of the pneumatic clamping mechanism to rotate, so that the clamping end of the pneumatic clamping mechanism drives the metal rack to rotate. This design achieves automatic face changing during multi-face processing of the metal rack by dynamically rotating the metal rack, solving the problems of cumbersome procedures, low efficiency and poor practicality caused by repeated disassembly and repositioning in traditional methods.

[0014] This invention uses a motor to drive a drive rod to rotate, which in turn drives a bevel gear and a bevel gear to rotate an arc-shaped roller. By utilizing the friction of the rubber strip on the arc-shaped roller and the guiding effect of the ball bearings at the end of the clamping plate, the metal rack can be precisely translated and positioned, allowing the rack to automatically move to the bottom of the drilling mechanism according to the processing hole position, ultimately forming a rapid processing flow of dynamic feeding and multi-faceted processing.

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-6 As shown, this utility model is a drilling device for processing metal racks, including a frame 1, a pneumatic clamping mechanism 2 is provided on the surface of the frame 1, a rotation adjustment mechanism 3 is provided inside the pneumatic clamping mechanism 2, two support clamping mechanisms 4 are provided on both sides of the frame 1, a drive feeding mechanism 5 is provided inside the support clamping mechanism 4, and a drilling mechanism 6 is provided on the surface of the frame 1. The pneumatic clamping mechanism 2 is used to clamp and fix the metal rack. The clamping end of the pneumatic clamping mechanism 2 is driven to rotate by the rotating end of the rotary adjustment mechanism 3, so that the clamping end of the pneumatic clamping mechanism 2 drives the metal rack to rotate.

[0022] The metal rack passes sequentially through the support end of the support clamping mechanism 4 and the clamping end of the pneumatic clamping mechanism 2. The support end of the support clamping mechanism 4 supports both ends of the metal rack, and the clamping end of the pneumatic clamping mechanism 2 clamps and fixes the middle of the metal rack. The drilling mechanism 6 is then driven to complete the drilling of the metal rack. When drilling is required on other sides of the metal rack, the rotary adjustment mechanism 3 is driven to rotate the clamping end of the pneumatic clamping mechanism 2, causing the clamping end of the pneumatic clamping mechanism 2 to rotate the metal rack. Then, the other sides of the metal rack are drilled. After completion, the feeding mechanism 5 drives the metal rack to slide inside the pneumatic clamping mechanism 2, so that the next drilling position of the metal rack reaches below the drilling mechanism 6.

[0023] The metal rack is clamped and fixed by the pneumatic clamping mechanism 2. The rotating end of the rotary adjustment mechanism 3 drives the clamping end of the pneumatic clamping mechanism 2 to rotate, so that the clamping end of the pneumatic clamping mechanism 2 drives the metal rack to rotate. This design realizes automatic face changing when the metal rack is processed on multiple sides by dynamically rotating the metal rack, which solves the problems of cumbersome process, low efficiency and poor practicality caused by repeated disassembly and repositioning in the traditional method.

[0024] In one embodiment, the pneumatic clamping mechanism 2 includes a placement plate 201, which is fixedly mounted on the surface of the frame 1. A drive ring 202 is rotatably connected inside the placement plate 201, and a clamping plate 203 is slidably connected inside the drive ring 202. A piston 204 is fixedly connected to one end of the clamping plate 203. An air passage 205 is provided inside the drive ring 202, which communicates with and compresses the piston 204. An air inlet pipe 206 is fixedly connected to one side of the placement plate 201, and one end of the air inlet pipe 206 communicates with the air passage 205 on the side of the drive ring 202. A ball bearing 207 is movably connected to one end of the clamping plate 203.

[0025] By connecting the air inlet pipe 206 to the air delivery end of the air pump, the metal rack passes through the support clamping mechanism 4 and the drive ring 202 in sequence. The support clamping mechanism 4 limits and clamps the metal rack. The air pump is started to input air into the air inlet pipe 206, so that the air enters the drive ring 202 through the air passage pipe 205 and squeezes the piston 204 inside the drive ring 202. The piston 204 drives the clamping plate 203 to slide inside the drive ring 202, so that one end of the clamping plate 203 contacts and presses the metal rack, thus completing the fixation of the metal rack.

[0026] The air pump drives the core components inside the pump to move through mechanical means, periodically changing the gas volume in the sealed chamber. When the volume increases, it draws in outside air, and when the volume decreases, it compresses the air forcefully, causing the distance between gas molecules to shrink and the pressure to increase. The compressed gas then enters the air inlet pipe 206.

[0027] In one embodiment, the rotary adjustment mechanism 3 includes a drive gear 301, which is rotatably connected inside the placement plate 201. A toothed groove 302 is formed on the surface of the drive ring 202, and the toothed groove 302 meshes with the drive gear 301. A motor 303 is fixedly installed at one end of the placement plate 201, and the output shaft of the motor 303 is fixedly connected to the drive gear 301. An ash storage trough 304 is formed in the middle of the placement plate 201.

[0028] After the metal rack is fixed, the motor 303 drives the drive gear 301 to rotate, which in turn drives the drive ring 202 to rotate through the tooth groove 302. The drive ring 202 rotates inside the placement plate 201, causing the metal rack to rotate. The ash storage trough 304 facilitates the collection of processing debris from the metal rack.

[0029] When the drive ring 202 rotates inside the placement plate 201, the air passage 205 on one side of the drive ring 202 is always in contact with the inside of the placement plate 201 and is connected to the air inlet pipe 206, so as not to affect its air intake; the connection between the drive ring 202 and the inside of the placement plate 201 is equipped with a sealing ring and an oil seal, which can be referred to as the sealing structure of the air valve.

[0030] In one embodiment, the support and clamping mechanism 4 includes a mounting base 401, which is fixedly connected inside the frame 1. A bidirectional screw 402 is rotatably connected inside the mounting base 401. A movable frame 403 is threadedly connected to the surface of the bidirectional screw 402. An arc-shaped roller 404 is rotatably connected inside the movable frame 403. A second motor 405 is fixedly connected to one side of the mounting base 401. The output shaft of the second motor 405 is fixedly connected to the bidirectional screw 402.

[0031] The metal rack is passed between the arc-shaped rollers 404. The bidirectional screw 402 is driven to rotate by the motor 405. The bidirectional screw 402 drives the movable frame 403 to slide inside the mounting base 401. At the same time, the movable frame 403 drives the arc-shaped rollers 404 to move towards the metal rack for self-centering, thereby clamping and limiting the metal rack.

[0032] In one embodiment, the aforementioned drive feeding mechanism 5 includes a drive rod 501, which is rotatably connected inside the mounting base 401. A bevel gear 502 is splined on the surface of the drive rod 501. The bevel gear 502 is rotatably connected inside the movable frame 403. A bevel gear 503 meshes with the surface of the bevel gear 502. The bevel gear 503 is fixedly connected to one end of the arc-shaped roller 404. A rubber strip 504 is fixedly connected to the surface of the arc-shaped roller 404. A motor 505 is fixedly connected to one side of the mounting base 401. The output shaft of the motor 505 is fixedly connected to the drive rod 501.

[0033] When feeding is required, motor 3 505 drives drive rod 501 to rotate, which in turn drives bevel gear 1 502 to rotate, which in turn drives bevel gear 2 503 to rotate, thereby driving arc roller 404 to rotate. The rubber strip 504 on the surface of arc roller 404 enhances the friction between the arc roller 404 and the metal rack, thereby moving the metal rack on the surface of arc roller 404. At the same time, the metal rack slides on the surface of ball bearing 207 at one end of clamping plate 203, achieving the effect of fixed-point feeding. According to the position of the machining hole, the metal rack is moved to below the drilling mechanism 6.

[0034] In one embodiment, the drilling mechanism 6 includes a fixed frame 601, which is fixedly connected to the surface of the frame 1. A motor 602 is fixedly connected to one end of the fixed frame 601. A lead screw 603 is fixedly connected to the output shaft of the motor 602. The lead screw 603 is rotatably connected inside the fixed frame 601. A lifting plate 604 is threadedly connected to the surface of the lead screw 603. A drilling machine body 605 is fixedly installed on the surface of the lifting plate 604.

[0035] Open the drilling machine body 605, and drive the lead screw 603 to rotate through the motor 602. The lead screw 603 drives the lifting plate 604 to move, and the lifting plate 604 drives the drilling machine body 605 to process and drill holes in the metal rack in the placement plate 201.

[0036] The drilling machine body 605 consists of a drill bit and a power source. The power source drives the drill bit to rotate at high speed, and the cutting edge of the drill bit applies pressure to the material and cuts continuously to form a hole.

[0037] Through the above technical solution, 1. By passing the metal rack sequentially through the arc-shaped roller 404 and the drive ring 202, the double-headed screw 402 is driven to rotate by the motor 405, causing the double-headed screw 402 to drive the movable frame 403 to slide inside the mounting base 401. Simultaneously, the movable frame 403 drives the arc-shaped roller 404 to move towards the metal rack for self-centering, thus clamping and limiting the metal rack. The air pump is then started, inputting air into the air inlet pipe 206, allowing the air to enter the drive ring 202 through the air passage pipe 205. This air compresses the piston 204 inside the drive ring 202, causing the piston 204 to drive the clamping plate 203 inside the drive ring 202. The sliding mechanism causes one end of the clamping plate 203 to contact and press the ball bearing 207 against the metal rack, thus fixing the middle of the metal rack. The motor 303 drives the drive gear 301 to rotate, which in turn drives the drive ring 202 to rotate through the tooth groove 302. The drive ring 202 rotates inside the placement plate 201, causing the metal rack to rotate and allowing it to rotate to any side. This design achieves automatic face changing during multi-face processing of the metal rack by dynamically rotating it, solving the problems of cumbersome procedures, low efficiency, and poor practicality caused by repeated disassembly and repositioning in traditional methods.

[0038] 2. The drive rod 501 is driven to rotate by the motor 3 505, which in turn drives the bevel gear 1 502 to rotate. The bevel gear 1 502 then drives the bevel gear 2 503 to rotate, thereby driving the arc roller 404 to rotate. The rubber strip 504 on the surface of the arc roller 404 enhances the friction between the metal rack and the roller, thus moving the metal rack on the surface of the arc roller 404. At the same time, the metal rack slides on the surface of the ball bearing 207 at one end of the clamping plate 203, achieving the effect of fixed-point feeding. According to the position of the machining hole, the metal rack is moved to the bottom of the drilling mechanism 6. This design, through automatic feeding and dynamic rotation, realizes the automatic and precise positioning of the metal rack in the drilling station, thereby completing continuous multi-faceted processing in conjunction with the dynamic rotation mechanism.
