Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to an environmentally friendly drilling equipment for precision hardware processing. Background Art

[0002] Hardware refers to tools made by processing and casting metals such as gold, silver, copper, iron, and tin. They are used to fix things, process things, and decorate, such as mold hardware, mechanical hardware, daily hardware, pipe hardware, etc. In the processing of hardware, drilling is a very important link.

[0003] The environmentally friendly drilling equipment currently on the market for hardware processing requires manual rotation of the pipe to the desired drilling position for adjustment when drilling holes at different circumferential positions of the pipe, resulting in low accuracy. Summary of the invention

[0004] The invention provides an environmentally friendly drilling device for precision hardware processing, which can overcome certain defects of the prior art.

[0005] An environmentally friendly drilling device for precision hardware processing according to the present invention comprises an operating table, a rotating assembly is provided at one end of the operating table, the rotating assembly comprises a fixed ring seat fixedly provided at the operating table, an outer gear ring is rotatably provided at the fixed ring seat, and a drilling mechanism for drilling is fixedly provided at the side wall of the outer gear ring;

[0006] A limit assembly is fixedly provided at the operating table, and the limit assembly includes a fixed seat fixed at the bottom of the operating table, a gear meshing with the outer gear ring is rotatably provided at the fixed seat, and a locking piece is provided between the fixed seat and the gear, and the locking piece is used to lock or unlock the gear.

[0007] Preferably, two positioning components with adjustable spacing are symmetrically provided on the operating table, and the two positioning components are used to limit the side walls of the pipe fitting.

[0008] Through the above structure, the side wall of the pipe is limited by two positioning components with adjustable spacing, which can ensure that the pipe maintains a stable posture during the drilling process and will not shift due to external force or vibration. At the same time, it can adapt to pipes of different diameters or sizes, so that the same device can be used to process pipes of various specifications without frequent replacement of equipment or adjustment of fixtures, thereby improving the scope of use of the equipment.

[0009] Preferably, the drilling mechanism includes a shell fixedly arranged at the side wall of the outer gear ring, a mounting cavity is arranged in the shell, a sleeve is arranged in the mounting cavity, a connecting rod is rotatably arranged in the sleeve, a worm gear is arranged above the connecting rod and slides along the length direction of the connecting rod; a worm gear meshing with the worm gear is also arranged at the mounting cavity, and one end of the worm gear is fixed at the output end of the motor; a ring-shaped groove is formed on the inner wall of the sleeve, and a convex portion matching the groove is formed on the side wall of the connecting rod.

[0010] Through the above structure, the connecting rod can be adjusted in the height direction, thereby controlling the feed depth and angle of the drill bit, so that the drilling mechanism can adapt to the drilling requirements of different thicknesses and angles.

[0011] Preferably, a fixing block is provided at the side wall of the sleeve, a slide groove corresponding to the fixing block is formed at the inner wall of the installation cavity, the fixing block is slidably arranged in the slide groove, and a first telescopic component for driving the fixing block to reciprocate is fixed at the bottom of the fixing block.

[0012] Through the above structure, by accurately controlling the position and moving speed of the casing, it is possible to ensure that the drill bit maintains a stable posture and speed during the drilling process, thereby improving the drilling accuracy and helping to reduce drilling deviation and surface roughness problems caused by workpiece movement or vibration.

[0013] Preferably, the connecting rod has a telescopic portion located above the sleeve, a spline is formed at the side wall of the telescopic portion, and a spline groove matching the spline is formed at the worm gear; a drill chuck is fixedly provided at the bottom of the connecting rod, and a drill bit is detachably mounted at the bottom of the drill chuck.

[0014] The telescopic part design of the connecting rod allows it to telescope above the casing, so that the feed depth of the drill bit can be accurately controlled. At the same time, by adjusting the extended length of the telescopic part, the feed amount of the drill bit can be conveniently adjusted to meet the requirements of drilling depth for different processing needs.

[0015] The splines on the side wall of the telescopic part cooperate with the spline grooves at the worm gear to form a stable transmission connection. This connection method can not only withstand large torque and axial force, but also ensure the accuracy and stability during the transmission process. At the same time, the close cooperation between the splines and the spline grooves reduces the gap and vibration during the transmission process, which helps to improve the accuracy and surface quality of drilling.

[0016] Preferably, a guide plate for guiding is fixedly provided on the inner wall of the installation cavity, and a spline groove for the telescopic part to movably penetrate is formed on the guide plate.

[0017] Through the above structure, the guide plate is fixedly arranged on the inner wall of the installation cavity, providing precise guidance for the telescopic part of the connecting rod. When the telescopic part performs telescopic movement, the guide plate can ensure that it moves smoothly on a predetermined trajectory, avoiding processing errors caused by offset or shaking, and improving drilling accuracy. At the same time, the guide plate not only plays a guiding role, but also serves as a supporting structure between the connecting rod and the installation cavity, increasing the stability of the connecting rod during the telescopic process, reducing deviations caused by vibration or external force interference, and helping to maintain the stability of the drill bit during the drilling process, thereby improving processing quality and efficiency.

[0018] Preferably, the limiting assembly includes two fixing seats symmetrically fixed along the outer gear ring at the bottom of the operating table, and the two fixing seats are rotatably provided with gears meshing with the outer gear ring near the side walls of the outer gear ring.

[0019] Through the above structure, by symmetrically arranging two fixing seats on both sides of the outer gear ring and rotatably installing a gear meshing with the outer gear ring on each fixing seat, accurate and stable locking of any position of the outer gear ring after rotation is achieved.

[0020] Preferably, an extension column is fixedly provided on one side of the fixed seat away from the gear, and a sliding cavity is provided in the extension column for installing a locking piece. A connecting plate is provided between the two locking pieces, and a second telescopic component for driving the connecting plate to move back and forth is fixedly provided at the bottom of the operating table.

[0021] Through the above structure, an extension column is arranged on the side of the fixing seat away from the gear, and a sliding cavity is designed inside the extension column to install a locking piece, so that a more flexible limit control of the outer gear ring is realized. When the rotation of the outer gear ring needs to be adjusted, that is, the drilling position of the drilling mechanism, the gear can be limited by controlling the locking piece, thereby realizing the limit of the gear on the outer gear ring. Not only the accuracy of the limit is improved, but also the flexibility of adjustment is increased.

[0022] Preferably, a handle for holding is fixedly provided on the outer wall of the shell, and a push switch electrically connected to the first telescopic component is provided on the inner wall of the handle.

[0023] Through the above structure, the handle is fixedly arranged on the outer wall of the shell, providing the user with a stable and comfortable gripping point, so that the user can easily rotate the drilling mechanism. At the same time, the push switch is arranged on the inner wall of the handle and is electrically connected to the first telescopic component, so that the user can control the telescopic action of the first telescopic component by simply pressing the switch, thereby achieving precise control of the casing and the drill bit, which not only improves the convenience of operation, but also helps to improve processing accuracy and efficiency.

[0024] Preferably, the locking member comprises a mounting plate slidably arranged in the sliding cavity, a connecting rod is fixedly arranged at one end of the mounting plate away from the fixing seat, the connecting rod movably passes through one end of the extension column and is fixedly arranged at the connecting plate, a spring is fixedly arranged between the mounting plate and the inner wall of the sliding cavity on one side close to the connecting plate, and the spring is used to provide elastic force to press the mounting plate toward the fixing seat;

[0025] The locking piece has two rotatably connected mounting tubes, which are respectively arranged at the gear and the fixing seat, with spline grooves formed at the inner walls of the mounting tubes, and a latch matched with the spline grooves at the mounting tubes fixedly arranged at one side of the mounting plate away from the connecting rod.

[0026] Through the above structure, the mounting plate is slidably arranged in the sliding cavity and is connected to the connecting plate through a connecting rod. When the second telescopic component drives the connecting plate to move, the connecting rod will drive the mounting plate to move back and forth in the sliding cavity, so that the locking member can respond quickly with the movement of the connecting plate, thereby realizing the locking and unlocking of the external gear ring. At the same time, a spring is fixed between the mounting plate and the inner wall of the sliding cavity close to the connecting plate. The elastic force of the spring acts on the mounting plate, so that it always has a tendency to be pressed toward the fixed seat, which not only helps to maintain the stability of the mounting plate in the sliding cavity, but also ensures the close fit between the latch and the spline groove in the mounting tube, thereby improving the reliability of the locking.

[0027] Specifically, the locking member has two rotatably connected mounting tubes, which are respectively arranged at the gear and the fixed seat. The spline groove on the inner wall of the mounting tube cooperates with the latch to form a stable transmission connection. When the mounting plate moves, the latch will be inserted into or pulled out of the spline groove of the mounting tube, thereby locking or unlocking the transmission relationship between the gear and the outer gear ring.

[0028] The beneficial effects of the present invention are as follows:

[0029] When the present invention is in use, the pipe fitting to be drilled is placed on the operating table, and the pipe fitting is then fixed directly under the drilling mechanism. The drilling mechanism can then be rotated to adjust the drilling mechanism around the axis of the pipe fitting to the drilling position, thereby ensuring a high degree of accuracy in the drilling position. The drilling operation can be performed immediately when the drilling mechanism is rotated to any desired position, and there is no need to manually rotate the pipe fitting to the desired drilling position for adjustment, thereby improving the accuracy of the drilling.

DETAILED DESCRIPTION

[0038] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0042] When the present invention is in use, the pipe fitting to be drilled is placed on the operating table 100, and then the pipe fitting is fixed directly under the drilling mechanism 120. The drilling mechanism 120 can then be rotated to adjust the drilling mechanism 120 to the drilling position around the axis of the pipe fitting, thereby ensuring a high degree of accuracy in the drilling position. The drilling operation can be performed immediately when the drilling mechanism 120 is rotated to any desired position, without the need to manually rotate the pipe fitting to the desired drilling position for adjustment, thereby improving the accuracy of the drilling.

[0043] In this embodiment, two positioning components 140 with adjustable spacing are symmetrically provided on the operating table 100, and the two positioning components 140 are used to limit the side walls of the pipe fitting.

[0044] Through the above structure, the side wall of the pipe is limited by two positioning components 140 with adjustable spacing, which can ensure that the pipe maintains a stable posture during the drilling process and will not shift due to external force or vibration. At the same time, it can adapt to pipes of different diameters or sizes, so that the same device can be used to process pipes of various specifications without frequent replacement of equipment or adjustment of fixtures, thereby improving the scope of use of the equipment.

[0045] In this embodiment, the drilling mechanism 120 includes a shell 310 fixedly arranged on the side wall of the outer gear ring 220, and an installation cavity is provided in the shell 310, and a sleeve 410 is provided in the installation cavity. A connecting rod 440 is rotatably provided in the sleeve 410, and a worm gear 460 is provided above the connecting rod 440 and slides along the length direction of the connecting rod 440; a worm 510 meshing with the worm gear 460 is also provided at the installation cavity, and one end of the worm 510 is fixedly arranged at the output end of the motor 520; an annular groove is formed on the inner wall of the sleeve 410, and a convex portion 443 cooperating with the groove is formed on the side wall of the connecting rod 440.

[0046] Through the above structure, the connecting rod 440 can be adjusted in the height direction, thereby controlling the feed depth and angle of the drill bit, so that the drilling mechanism can adapt to the drilling requirements of different thicknesses and angles.

[0047] In this embodiment, a fixed block 420 is provided on the side wall of the sleeve 410, and a sliding groove corresponding to the fixed block 420 is formed on the inner wall of the installation cavity. The fixed block 420 is slidably arranged in the sliding groove, and a first telescopic component 430 for driving the fixed block 420 to reciprocate is fixed at the bottom of the fixed block 420.

[0048] Through the above structure, by accurately controlling the position and moving speed of the casing 410, it is possible to ensure that the drill bit maintains a stable posture and speed during the drilling process, thereby improving the drilling accuracy and helping to reduce drilling deviation and surface roughness problems caused by workpiece movement or vibration.

[0049] In this embodiment, the connecting rod 440 has a telescopic portion 442 located above the sleeve 410, a spline is formed at the side wall of the telescopic portion 442, and a spline groove matching the spline is formed at the worm gear 460; a drill chuck 441 is fixedly provided at the bottom of the connecting rod 440, and a drill bit 340 is detachably installed at the bottom of the drill chuck 441.

[0050] The telescopic portion 442 of the connecting rod 440 is designed to allow it to perform telescopic movement above the sleeve 410, so that the feed depth of the drill bit 340 can be precisely controlled. At the same time, by adjusting the extended length of the telescopic portion 442, the feed amount of the drill bit can be conveniently adjusted to meet the requirements of different processing needs for drilling depth.

[0051] The splines on the side wall of the telescopic part 442 cooperate with the spline grooves at the worm wheel 460 to form a stable transmission connection. This connection method can not only withstand large torque and axial force, but also ensure the accuracy and stability during the transmission process. At the same time, the close fit between the splines and the spline grooves reduces the gap and vibration during the transmission process, which helps to improve the accuracy and surface quality of drilling.

[0052] In this embodiment, a guide plate 450 for guiding is fixedly provided on the inner wall of the installation cavity, and a spline groove is formed on the guide plate 450 for the telescopic portion 442 to movably penetrate.

[0053] Through the above structure, the guide plate 450 is fixedly arranged on the inner wall of the installation cavity, providing precise guidance for the telescopic part 442 of the connecting rod 440. When the telescopic part 442 performs telescopic movement, the guide plate 450 can ensure that it moves smoothly on a predetermined trajectory, avoiding processing errors caused by offset or shaking, and improving drilling accuracy. At the same time, the guide plate 450 not only plays a guiding role, but also serves as a supporting structure between the connecting rod 440 and the installation cavity, increasing the stability of the connecting rod 440 during the telescopic process, reducing the deviation caused by vibration or external force interference, and helping to maintain the stability of the drill bit during the drilling process, thereby improving the processing quality and efficiency.

[0054] In this embodiment, the limiting assembly 130 includes two fixing seats 610 symmetrically fixed along the outer gear ring 220 at the bottom of the operating table 100 , and the two fixing seats 610 are rotatably provided with gears 620 meshing with the outer gear ring 220 near the side walls of the outer gear ring 220 .

[0055] Through the above structure, by symmetrically setting two fixing seats 610 on both sides of the outer gear ring 220 and rotatably installing a gear 620 meshing with the outer gear ring 220 on each fixing seat 610, accurate and stable locking of the outer gear ring 220 at any position after rotation is achieved.

[0056] In this embodiment, an extension column 630 is fixedly provided on the side of the fixed seat 610 away from the gear 620. The extension column 630 has a sliding cavity for installing a locking member. A connecting plate 640 is provided between the two locking members. A second telescopic component 650 for driving the connecting plate 640 to move back and forth is fixedly provided at the bottom of the operating table 100.

[0057] Through the above structure, an extension column 630 is arranged on the side of the fixing seat 610 away from the gear 620, and a sliding cavity is designed inside the extension column 630 to install a locking member, so that a more flexible limit control of the outer gear ring 220 is realized. When the rotation of the outer gear ring 220 needs to be adjusted, that is, the drilling position of the drilling mechanism 120, the gear 620 can be limited by controlling the locking member, thereby realizing the limit of the outer gear ring 220 by the gear 620. Not only the accuracy of the limit is improved, but also the flexibility of adjustment is increased.

[0058] In this embodiment, a handle 320 for holding is fixedly provided on the outer wall of the housing 310 , and a push switch 330 electrically connected to the first telescopic component 430 is provided on the inner wall of the handle 320 .

[0059] Through the above structure, the handle 320 is fixedly arranged on the outer wall of the shell 310, providing a stable and comfortable gripping point for the user, so that the user can easily rotate the drilling mechanism 120. At the same time, the press switch 330 is arranged on the inner wall of the handle 320 and is electrically connected to the first telescopic component 430, so that the user can control the telescopic action of the first telescopic component 430 by simply pressing the switch, thereby achieving precise control of the casing 410 and the drill bit 340, which not only improves the convenience of operation, but also helps to improve processing accuracy and efficiency.

[0060] In this embodiment, the locking member includes a mounting plate 730 slidably disposed in the sliding cavity, a connecting rod 750 is fixedly disposed at one end of the mounting plate 730 away from the fixing seat 610, the connecting rod 750 movably passes through one end of the extension column 630 and is fixedly disposed at the connecting plate 640, a spring 760 is fixedly disposed between the mounting plate 730 and the inner wall of the sliding cavity on the side close to the connecting plate 640, and the spring 760 is used to provide an elastic force to press the mounting plate 730 toward the fixing seat 610;

[0061] The locking member has two rotatably connected mounting tubes 710, which are respectively arranged at the gear 620 and the fixing seat 610. A spline groove is formed on the inner wall of the mounting tube 710, and a latch 740 matching the spline groove of the mounting tube 710 is fixedly provided on the side of the mounting plate 730 away from the connecting rod 750.

[0062] Through the above structure, the mounting plate 730 is slidably arranged in the sliding cavity and is connected to the connecting plate 640 through the connecting rod 750. When the second telescopic component 650 drives the connecting plate 640 to move, the connecting rod 750 will drive the mounting plate 730 to reciprocate in the sliding cavity, so that the locking member can respond quickly with the movement of the connecting plate 640, thereby realizing the locking and unlocking of the external gear ring 220. At the same time, a spring 760 is fixed between the mounting plate 730 and the inner wall of the sliding cavity close to the connecting plate 640. The elastic force of the spring 760 acts on the mounting plate 730, so that it always has a tendency to be pressed toward the fixed seat 610, which not only helps to maintain the stability of the mounting plate 730 in the sliding cavity, but also ensures the close fit between the latch pin 740 and the spline groove in the mounting tube 710, thereby improving the reliability of the locking.

[0063] Specifically, the locking member has two rotatably connected mounting tubes 710, which are respectively arranged at the gear 620 and the fixed seat 610. The spline groove on the inner wall of the mounting tube 710 cooperates with the latch 740 to form a stable transmission connection. When the mounting plate 730 moves, the latch 740 will be inserted into or pulled out of the spline groove of the mounting tube 710, thereby realizing the locking or unlocking of the transmission relationship between the gear 620 and the outer gear ring 220.

[0064] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0065] The present invention and its implementation methods are described schematically above, and the description is not restrictive. The embodiments shown in the embodiments are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the embodiments and designs a structure and an implementation method similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
