Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of metal product drilling machines, and specifically relates to a metal product drilling machine. Background Technology
[0002] Metal drilling machines are a type of equipment that uses a drill bit to make holes in metal materials. Through rotation or impact cutting, the drill bit makes holes in the metal surface. Common metal drilling machines include bench drills, vertical drills, and radial drills.
[0003] In the existing technology, most metal product drilling machines mainly use corresponding fixtures to clamp and fix the metal product to be processed, and then drill holes in the metal product through the cooperation of the drill bit and the drive mechanism. When drilling is carried out in this way, it is usually only possible to drill one side of the metal product. When it is necessary to drill the other side or the side at different angles, the metal product needs to be disassembled and repositioned. This makes the actual application flexibility of metal product drilling machines poor and unsuitable for multi-sided drilling of metal products, especially for pipe or rod-shaped metal products.
[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a drilling machine for metal products.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0006] The purpose of this utility model is to provide a metal product drilling machine that can perform multi-face drilling on the metal product to be processed according to the processing requirements.
[0007] To achieve the above objectives, a specific embodiment of this utility model provides a metal product drilling machine, including: a frame, a processing table, an active clamping assembly, and an auxiliary clamping assembly.
[0008] A processing table is mounted on top of the frame.
[0009] The active clamping assembly is fixedly mounted above the processing table. The active clamping assembly includes a fixed base, which is fixedly mounted above the processing table. An active limiting cylinder is rotatably mounted on the fixed base. A worm gear is engaged below the active limiting cylinder. An active clamping plate is mounted inside the active limiting cylinder.
[0010] The auxiliary clamping assembly is fixedly mounted on one side of the active limiting cylinder. The auxiliary clamping assembly includes a slide rail, which is fixedly mounted above the processing table. A slider is slidably mounted above the slide rail, and a driven limiting cylinder is rotatably mounted above the slider. A driven clamping plate is mounted inside the driven limiting cylinder.
[0011] In one or more embodiments of this utility model, the outer side of the active limiting cylinder is integrally formed with multiple worm gear teeth, all of which mesh with a worm. By engaging the worm with the worm gear teeth, the rotation of the worm can be used to move the worm gear teeth, thereby facilitating rotational control of the active limiting cylinder.
[0012] In one or more embodiments of this utility model, both ends of the worm gear are rotatably connected to limit plates, and the limit plates are fixedly connected to the fixed base. The limit plates serve to limit the assembly of the worm gear. An adjusting end is fixedly connected to one end of the worm gear outside the limit plates. The worm gear is rotated by controlling the rotation of the adjusting end.
[0013] In one or more embodiments of this utility model, both sides of the active limiting cylinder are integrally formed with supporting rings, and a pair of guide frames are fixedly connected above the fixed base. The pair of supporting rings and guide frames are rotatably engaged. The rotatable engagement between the supporting rings and guide frames can support and limit the movement of the active limiting cylinder.
[0014] In one or more embodiments of this utility model, marking scale lines are provided on the outer sides of both the pair of supporting rings and the guide frame. Users can observe and judge the rotation angle of the active limiting cylinder by observing the marking scale lines. A first anti-slip pad is fixedly attached to the side of the active limiting cylinder that is in contact with the active clamping plate. This ensures the stability and reliability of the clamping of the active limiting cylinder and the active clamping plate on the metal product to be processed.
[0015] In one or more embodiments of this utility model, a drive screw is rotatably mounted above the active clamping plate. The drive screw is threadedly connected to the active limiting cylinder, and a drive end is fixedly connected to one end of the drive screw outside the active limiting cylinder. By controlling the rotation of the drive end, the drive screw is rotated, thereby driving the worm gear to move up and down under the action of the internal and external threads. This allows the worm gear to cooperate with the active limiting cylinder to clamp and fix the metal product to be processed.
[0016] In one or more embodiments of this utility model, a locking bolt is threaded onto one side of the slider, and one end of the locking bolt located inside the slider contacts the outer surface of the slide rail. The locking bolt locks and positions the slider by pressing against the outer surface of the slide rail.
[0017] In one or more embodiments of this utility model, auxiliary support rings are fixedly connected to both sides of the driven limiting cylinder, and a pair of auxiliary guide frames are fixedly connected above the slider. Each pair of auxiliary guide frames is rotatably engaged with the auxiliary support rings. The driven limiting cylinder can be supported and limited by the rotatable engagement of the auxiliary support rings and the auxiliary guide frames.
[0018] In one or more embodiments of this utility model, auxiliary marking lines are provided on the outer sides of both the pair of auxiliary support rings and the auxiliary guide frame. The rotation angle of the driven limiting cylinder is observed and judged by observing the auxiliary marking lines. A second anti-slip pad is fixedly attached to the side of the driven limiting cylinder that is in close contact with the driven clamping plate. The provision of the second anti-slip pad improves the anti-slip performance of the driven limiting cylinder and the driven clamping plate, ensuring the stability and reliability of the driven limiting cylinder and the driven clamping plate in clamping and fixing the metal product to be processed.
[0019] In one or more embodiments of this utility model, an auxiliary screw is rotatably mounted above the driven clamping plate. The auxiliary screw passes through the driven limiting cylinder and is threadedly connected to the driven limiting cylinder. An auxiliary drive block is fixedly connected to one end of the auxiliary screw outside the driven limiting cylinder. By controlling the rotation of the auxiliary drive block, the auxiliary screw is driven to rotate, thereby allowing the auxiliary screw to drive the driven clamping plate to move up and down under the action of internal and external threads.

Detailed Implementation
[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0031] like Figures 1 to 6 As shown, a metal product drilling machine according to one embodiment of the present invention includes: a frame 1, a processing table 101, an active clamping assembly 2, and an auxiliary clamping assembly 3.
[0032] like Figure 1 As shown, a processing table 101 is mounted on top of the frame 1. The processing table 101 is used to assemble and limit the active clamping assembly 2 and the auxiliary clamping assembly 3, providing a processing platform for the metal products to be processed.
[0033] like Figures 1 to 3As shown, the active clamping assembly 2 is fixedly mounted above the processing table 101. The active clamping assembly 2 includes a fixed base 201, which is fixedly mounted above the processing table 101. The fixed base 201 supports and fixes the limiting plate 206 and the guide frame 209, thereby supporting and limiting the active limiting cylinder 202 and the supporting ring 208.
[0034] like Figures 1 to 2 As shown, an active limiting cylinder 202 is rotatably mounted on the fixed base 201. The active limiting cylinder 202 can support and limit the metal product to be processed.
[0035] like Figures 1 to 2 As shown, the outer side of the active limiting cylinder 202 is integrally formed with multiple worm gear teeth 205, all of which mesh with the worm 203. By engaging the worm 203 with the worm gear teeth 205, the rotation of the worm 203 can be driven to move the worm gear teeth 205, thereby facilitating the rotational control of the active limiting cylinder 202.
[0036] It is worth noting that the helix angle of the worm 203 is smaller than the equivalent friction angle between the multiple worm gear teeth 205, which allows the worm 203 to self-lock with the multiple worm gear teeth 205. The active limiting cylinder 202 can only be rotated and adjusted by driving the worm 203 to ensure the stability of the angle adjustment of the active limiting cylinder 202.
[0037] like Figures 1 to 2 As shown, both sides of the active limiting cylinder 202 are integrally formed with support rings 208, and a pair of guide frames 209 are fixedly connected to the top of the fixed base 201. The pair of support rings 208 and the guide frames 209 are rotatably engaged. The rotatable engagement between the support rings 208 and the guide frames 209 can support and limit the active limiting cylinder 202.
[0038] Specifically, both the outer sides of the pair of support rings 208 and the guide frame 209 are marked with scale lines. Users can observe and judge the rotation angle of the active limit cylinder 202 by observing the scale lines.
[0039] like Figure 5 As shown, a worm gear 203 is engaged below the active limiting cylinder 202. By controlling the rotation of the worm gear 203, the multiple worm gear teeth 205 are moved, thereby adjusting the angle of the active limiting cylinder 202.
[0040] like Figures 1 to 2As shown, both ends of the worm gear 203 are rotatably connected to limit plates 206, which are fixedly connected to the fixed base 201. The limit plates 206 serve to limit the assembly of the worm gear 203. An adjusting end 207 is fixedly connected to one end of the worm gear 203 outside the limit plates 206. The worm gear 203 is rotated by controlling the rotation of the adjusting end 207.
[0041] like Figure 3 As shown, the active limiting cylinder 202 is equipped with an active clamping plate 204. The active clamping plate 204 and the active limiting cylinder 202 cooperate to clamp and fix the metal product to be processed.
[0042] like Figure 3 As shown, a first anti-slip pad 210 is fixedly attached to the side of the active limiting cylinder 202 that is in close contact with the active clamping plate 204. This ensures the stability and reliability of the active limiting cylinder 202 and the active clamping plate 204 in clamping the metal product to be processed.
[0043] like Figures 1 to 3 As shown, a drive screw 211 is rotatably mounted above the active clamping plate 204. The drive screw 211 is threadedly connected to the active limiting cylinder 202, and a drive end 212 is fixedly connected to one end of the drive screw 211 outside the active limiting cylinder 202. By controlling the rotation of the drive end 212, the drive screw 211 is driven to rotate, thereby allowing the drive screw 211 to drive the worm gear 203 to move up and down under the action of the internal and external threads. This allows the worm gear 203 to cooperate with the active limiting cylinder 202 to clamp and fix the metal product to be processed.
[0044] like Figures 3 to 5 As shown, the auxiliary clamping assembly 3 is fixedly mounted on one side of the active limiting cylinder 202. The auxiliary clamping assembly 3 includes a slide rail 301, which is fixedly mounted above the processing table 101. A slider 302 is slidably mounted above the slide rail 301. By sliding the slider 302 on the slide rail 301, the driven limiting cylinder 303 is horizontally adjusted, thereby allowing the auxiliary clamping assembly 3 to be adaptively adjusted according to the specific processing requirements of the metal product to be processed, thus improving the applicability of the metal product drilling machine.
[0045] like Figure 1 As shown, a locking bolt 305 is threadedly connected to one side of the slider 302. One end of the locking bolt 305 located inside the slider 302 contacts the outer surface of the slide rail 301. By pressing the locking bolt 305 against the outer surface of the slide rail 301, the locking bolt 305 can lock and position the slider 302.
[0046] like Figures 1 to 4As shown, a driven limiting cylinder 303 is rotatably mounted above the slider 302. The driven limiting cylinder 303 serves to connect the slider 302 and the auxiliary guide frame 307.
[0047] like Figures 1 to 4 As shown, auxiliary support rings 306 are fixedly connected to both sides of the driven limiting cylinder 303, and a pair of auxiliary guide frames 307 are fixedly connected above the slider 302. Both auxiliary guide frames 307 are rotatably engaged with the auxiliary support rings 306. The driven limiting cylinder 303 can be supported and limited by the rotatable engagement of the auxiliary support rings 306 and the auxiliary guide frames 307.
[0048] Specifically, auxiliary marking lines are provided on the outer sides of both the pair of auxiliary support rings 306 and the auxiliary guide frame 307. The rotation angle of the driven limit cylinder 303 is observed and judged by observing the auxiliary marking lines.
[0049] like Figures 3 to 5 As shown, a driven clamping plate 304 is installed inside the driven limiting cylinder 303. The metal product to be processed is clamped and fixed by the cooperation between the driven clamping plate 304 and the driven limiting cylinder 303.
[0050] like Figures 3 to 5 As shown, a second anti-slip pad 308 is fixedly attached to the side of the driven limiting cylinder 303 that is in close contact with the driven clamping plate 304. By setting the second anti-slip pad 308, the anti-slip performance of the driven limiting cylinder 303 and the driven clamping plate 304 is improved, ensuring the stability and reliability of the driven limiting cylinder 303 and the driven clamping plate 304 in clamping and fixing the metal product to be processed.
[0051] like Figures 3 to 5 As shown, an auxiliary screw 309 is rotatably mounted above the driven clamping plate 304. The auxiliary screw 309 passes through the driven limiting cylinder 303 and is threadedly connected to the driven limiting cylinder 303. An auxiliary drive block 310 is fixedly connected to one end of the auxiliary screw 309 outside the driven limiting cylinder 303. By controlling the rotation of the auxiliary drive block 310, the auxiliary screw 309 is driven to rotate, thereby allowing the auxiliary screw 309 to drive the driven clamping plate 304 to move up and down under the action of internal and external threads.
[0052] In practical use, the distance between the active limiting cylinder 202 and the driven limiting cylinder 303 is adjusted by sliding the slider 302 on the slide rail 301 according to the actual size of the metal product to be processed, and the slider 302 is locked and fixed by tightening the locking bolt 305.
[0053] During drilling, the metal product to be processed can be inserted into the active limiting cylinder 202 and the driven limiting cylinder 303. The active clamping plate 204 and the driven clamping plate 304 can be moved by controlling the rotation of the drive end 212 and the first anti-slip pad 210. The active limiting cylinder 202 and the active clamping plate 204, and the driven limiting cylinder 303 and the driven clamping plate 304 can clamp and fix both sides of the metal product to be processed. Then, the drilling process can be performed on the metal product to be processed by controlling the rotation and movement of the drill bit.
[0054] When drilling is required at different angles on a metal product, the worm gear 203 can be driven to rotate by controlling the rotation of the adjusting end 207. The active limiting cylinder 202 can rotate under the action of the worm gear teeth 205 and the worm gear 203. The angle of the metal product to be processed is adjusted by rotating the active limiting cylinder 202. During the adjustment process, the angle adjustment status of the active limiting cylinder 202 can be observed and judged by observing the marking scale lines. Then, drilling can be performed at different angles on the metal product to be processed.
[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
