Description

Technical Field

[0001] This utility model relates to the field of magnetic drill technology, and in particular to a rotating mechanism with a fast adjustable shaft hole fit. Background Technology

[0002] In the field of machining, magnetic drills, thanks to the adsorption properties of electromagnetic chucks on metal workpieces, can be fixed to the surface of metal workpieces without additional clamps, achieving efficient drilling operations. They are widely used in steel structure manufacturing and equipment maintenance.

[0003] Traditional magnetic drills typically have a rigid connection between the drilling mechanism and the magnetic base, which can only achieve drilling in the vertical or horizontal direction. Therefore, when facing inclined workpieces (such as bridge truss nodes, ship curved bulkheads) or other workpieces that require oblique drilling, it is necessary to manually move the equipment and reposition it multiple times. Each repositioning takes a long time and may also cause deviations in drilling accuracy due to secondary adsorption errors. Utility Model Content

[0004] The purpose of this invention is to address the poor adaptability of magnetic drills to oblique drilling in the existing technology, which urgently needs improvement, and proposes a fast-adjustable shaft-hole mating rotating mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-adjustable shaft-hole mating rotating mechanism includes a magnetic base and a drilling mechanism. The drilling mechanism is located on top of the magnetic base and includes a drive unit, a drill shaft, and a height adjustment assembly. A drill bit is provided at the bottom end of the drill shaft.

[0007] The bottom of the magnetic base is equipped with an electromagnetic chuck;

[0008] The height adjustment component is used to drive the drive unit to move up and down, adjust the height of the drill bit, and thus control the drilling depth of the drill bit.

[0009] In some embodiments, the height adjustment assembly includes a vertical plate, a limiting slide rail, and a limiting slider, wherein the limiting slider is slidably connected to the limiting slide rail.

[0010] The vertical plate is provided with a support seat, and a threaded shaft is rotatably connected to the middle of the support seat. The support seat is used to maintain the horizontal height of the threaded shaft.

[0011] In some embodiments, an internal thread block is provided on one side of the drive unit, and the threaded shaft passes through the internal thread block. When the threaded shaft rotates, it drives the drive unit to move up and down through the internal thread block.

[0012] In some embodiments, an adjustment mechanism is provided between the magnetic base and the drilling mechanism, the adjustment mechanism being used to adjust the angle of the drill spindle;

[0013] The vertical plate has a side plate on its outer side, which partially surrounds the drilling mechanism and provides protection for the drilling mechanism.

[0014] In some embodiments, the adjusting mechanism includes a rotating part and a locking part, wherein the rotating part is used to adjust the drill spindle angle and the locking part is used to fix the drill spindle angle.

[0015] In some embodiments, the rotating part includes a rotating plate and a fixed plate, and the top of the fixed plate is provided with a hinge block, which is rotatably connected to the rotating plate by bolts.

[0016] In some embodiments, the locking part includes a fixing box and a fixing block. The top of the fixing box has a slot, and the bottom of the fixing block has a swing plate. The fixing box is provided with a locking member, which is used to lock the swing plate.

[0017] In some embodiments, the locking member includes an electromagnet disposed on the fixing box, and the swing plate is a magnetically responsive plate.

[0018] In some embodiments, the magnetic base is provided with a first power switch and a second power switch, the first power switch being used to control the electromagnetic chuck to be powered on and off, and the second power switch being used to control the electromagnet to be powered on and off.

[0019] In some embodiments, the fixed box is provided with a swing groove, and the swing plate is provided with a swing column that corresponds to and cooperates with the swing groove;

[0020] The fixed box is provided with an angle reference line, which corresponds to the swing groove, and the swing column is provided with a connecting line.

[0021] Compared with the prior art, this utility model provides a quick-adjustable shaft-hole mating rotation mechanism, which has the following beneficial effects.

[0022] 1. This utility model, through the hinged cooperation between the rotating plate and the hinge block in the rotating part, and the magnetic fixation between the electromagnet and the swing plate, can quickly adjust the angle of the drill bit without re-attaching the magnetic seat. The single angle adjustment time is greatly reduced compared with the traditional method of multiple adsorption and positioning, thereby significantly improving the processing efficiency of inclined and curved workpieces.

[0023] 2. In this utility model, the swing groove of the fixed box and the swing column of the swing plate form a trajectory constraint, which avoids the drilling mechanism from shaking during adjustment and ensures the verticality accuracy of the inclined drilling.

[0024] 3. This utility model, through the coordination of the angle reference line and the docking line, allows operators to intuitively read the drill spindle deflection angle, improving angle positioning accuracy compared to traditional visual estimation. It is especially suitable for batch processing of holes with multiple angles.

[0025] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Reference Figure 1-11 A quick-adjustable shaft-hole mating rotating mechanism includes a magnetic base 1 and a drilling mechanism 2. The drilling mechanism 2 is located on the top of the magnetic base 1. The drilling mechanism 2 includes a drive unit 201, a drill shaft 202 and a height adjustment component 3. The bottom end of the drill shaft 202 is provided with a drill bit 203.

[0041] The drive unit 201 is equipped with a motor and a gearbox. The motor is connected to the drill spindle 202 through the gearbox, and the motor drives the drill spindle 202 to drill.

[0042] The height adjustment component 3 is used to drive the drive unit 201 to move up and down, adjust the height of the drill bit 203, and thus control the drilling depth of the drill bit 203.

[0043] The height adjustment component 3 includes a vertical plate 301. A limiting slide rail 302 is provided on the side of the vertical plate 301 near the drive unit 201. A limiting slider 303 is provided on the side of the drive unit 201 near the vertical plate 301. The limiting slider 303 is slidably connected to the limiting slide rail 302.

[0044] A support base 304 is provided on the vertical plate 301. A threaded shaft 305 is rotatably connected to the middle of the support base 304. A crank 306 is provided at the top of the threaded shaft 305. An internal threaded block 307 is provided on the side of the drive unit 201 near the limiting slide rail 302. The threaded shaft 305 passes through the internal threaded block 307. The threaded shaft 305 and the internal threaded block 307 are adapted to each other. When the threaded shaft 305 rotates, it drives the drive unit 201 to move up and down through the internal threaded block 307. As another embodiment of the threaded shaft 305, the threaded shaft 305 can be driven by a lifting motor. The output end of the lifting motor is fixedly connected to the threaded shaft 305. The lifting motor is fixedly connected to the vertical plate 301, and the motor drive replaces manual operation.

[0045] The bottom of the magnetic base 1 is provided with an electromagnetic chuck 101. The magnetic base 1 is provided with a first power switch 102, which is used to control the power supply to and from the electromagnetic chuck 101.

[0046] In this invention, when the first power switch 102 is turned on, the electromagnetic chuck 101 at the bottom of the magnetic base 1 is energized to generate magnetic force, which adsorbs onto the surface of the metal workpiece, ensuring that the drilling mechanism 2 is firmly fixed on the metal workpiece, thereby improving the drilling accuracy.

[0047] During drilling, the motor inside the drive unit 201 is energized and started, driving the drill spindle 202 and drill bit 203 to rotate. Simultaneously, the height adjustment component 3 controls the distance between the drill bit 203 and the metal workpiece. Specifically, after the electromagnetic chuck 101 is magnetically fixed to the metal workpiece, the threaded shaft 305 is rotated by the crank handle 306. Under the limiting action of the limiting slide rail 302 on the limiting slider 303, as the threaded shaft 305 rotates, the drive unit 201, through the threaded shaft 305 and the internal thread... The threaded engagement of the threaded block 307 allows it to move up and down along the limiting slide rail 302. When the crank handle 306 rotates forward, the threaded engagement between the threaded shaft 305 and the internal threaded block 307 causes the drive unit 201 to move vertically downward. Similarly, when the crank handle 306 rotates in the reverse direction, the threaded engagement between the threaded shaft 305 and the internal threaded block 307 causes the drive unit 201 to move vertically upward. This adjusts the distance between the drill bit 203 and the metal workpiece, and thus adjusts the drilling depth of the drill bit 203 into the metal workpiece.

[0048] The support base 304 has a rotating groove inside, and a rotating disk is provided on the threaded shaft 305 at a position corresponding to the rotating groove. The rotating disk is movably connected inside the rotating groove. As another way of rotating connection between the threaded shaft 305 and the support base 304, a bearing is provided inside the support base 304. The outer ring of the bearing is fixed to the support base 304, and the inner ring of the bearing is fixedly connected to the threaded shaft 305.

[0049] During use, when drilling vertically downwards into a metal workpiece, the magnetic base 1 is vertically magnetically attached to the workpiece using the electromagnetic chuck 101 for drilling. When drilling horizontally into a metal workpiece, the magnetic base 1 is horizontally magnetically attached to the workpiece using the electromagnetic chuck 101 for drilling. However, when drilling at an angle into a metal workpiece, or when the angled surface of the workpiece cannot be directly magnetically fixed using the electromagnetic chuck 101, drilling becomes difficult. Therefore, the following improvements are made:

[0050] An adjustment mechanism is provided between the magnetic base 1 and the drilling mechanism 2. The adjustment mechanism is used to adjust the angle of the drill spindle 202.

[0051] A side plate 204 is provided on the outside of the vertical plate 301. The side plate 204 partially surrounds the drilling mechanism 2 and provides protection for the drilling mechanism 2.

[0052] Specifically, the adjustment mechanism includes a rotating part 4 and a locking part 5. The rotating part 4 is used to adjust the angle of the drill shaft 202, and the locking part 5 is used to fix the angle of the drill shaft 202.

[0053] In one embodiment, the rotating part 4 includes a rotating plate 401 located at the bottom of the side plate 204 and a fixed plate 402 located inside the magnetic base 1. The fixed plate 402 has a hinge block 403 at its top, a rotating groove 404 corresponding to and cooperating with the rotating plate 401 in its center, and a through hole 405 in its center. The rotating plate 401 has a through hole through which a bolt 406 passes, and the bolt 406 is installed inside both the through hole 405 and the through hole. The magnetic base 1 has an opening at its top, corresponding to the rotating plate 401, for the rotation of the rotating plate 401. Under the support of the rotating plate 401, a gap exists between the side plate 204 and the upper surface of the magnetic base 1, preventing the drilling mechanism 2 from contacting the magnetic base 1 during angle adjustment.

[0054] As one embodiment of the locking part 5, the locking part 5 includes a fixing box 501, which is fixedly connected to the magnetic base 1. The fixing box 501 and the magnetic base 1 are fixedly connected by a screw, and the magnetic base 1 is provided with a thread that corresponds to the screw.

[0055] The top of the fixed box 501 has a slot 502, and the side plate 204 has a fixing block 504 on the side near the fixed box 501. The bottom of the fixing block 504 has a swing plate 505. The fixed box 501 has a locking component for locking the swing plate 505. The locking component includes an electromagnet 507 on the fixed box 501, and the swing plate 505 is a magnetic response plate.

[0056] The magnetic base 1 is equipped with a second power switch 104, which is used to control the electromagnet 507 to be powered on and off.

[0057] When drilling a metal workpiece at an angle, before the metal workpiece contacts the drill bit 203, the crank handle 306 is first rotated around the bolt 406 to adjust the angle of the drill bit 203 to correspond to the angled part of the metal workpiece. Then, by turning on the second power switch 104, the electromagnet 507 is magnetically fixed to the swing plate 505, thereby fixing the angles of the side plate 204, the height adjustment component 3, the drive unit 201, and the drill spindle 202. Then, by turning the crank handle 306 clockwise, the distance between the drill bit 203 and the angled part of the metal workpiece is adjusted, thus realizing the drilling of the angled part of the metal workpiece and improving the adaptability of the magnetic drill to different metal workpieces during use.

[0058] As an optional solution, a swing groove 503 is provided on the fixed box 501, and a swing column 506 corresponding to the swing groove 503 is provided on the swing plate 505. During use, when the rotating plate 401 adjusts the angle with the bolt 406 as the center, the swing column 506 also moves along the path of the swing groove 503 with the bolt 406 as the center while the rotating plate 401 swings. The stability of the drive unit 201 and the drill shaft 202 during angle adjustment is improved by the swing groove 503 and the swing column 506.

[0059] Furthermore, an angle reference line 5011 is provided on the fixed box 501, which corresponds to the swing groove 503. A connecting line 5061 is provided on the swing column 506. When the drive unit 201 and the drill spindle 202 adjust their angles around the bolt 406, the angle reference line 5011 on the fixed box 501 and the connecting line 5061 on the swing column 506 facilitate the determination of the current rotation angle of the drive unit 201 and the drill spindle 202, thereby improving the machining accuracy of the drill bit 203 on the metal workpiece.
