Description

Technical Field

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

[0002] Furniture manufacturing is the process of transforming various raw materials into practical furniture products through a series of processes such as design, cutting, forming, surface treatment, and assembly. The manufacturing process includes raw material pretreatment, structural processing, surface treatment, assembly, and inspection. For example, a backrest office chair consists of a metal frame, seat, backrest, armrests, and foam padding. The metal frame is made by bending or assembling multiple sections of metal tubes and has multiple holes for mounting bolts. Then, bolts are used to assemble the metal frame, seat, backrest, and armrests through the holes in the metal frame.

[0003] In the current technology, before bending or assembling a metal frame, it is necessary to use a drilling device to open multiple holes in the metal tube. Usually, it is necessary to use a clamp to fix the metal tube, and then control the drill to go down and mark the position of the metal tube to carry out the drilling operation. In actual processing, symmetrical clamps hold metal tubes, and the clamping plates on both sides exert compressive stress on the surface of the metal tube, causing the compressive stress to concentrate locally and resulting in depressions on the surface of the metal tube. For thin-walled tubes or large-diameter tubes, the cross-section of the tube will be compressed from a circle to an ellipse. When the metal tube deforms, the originally marked drilling marks will be misaligned with the actual structural reference of the tube, thus affecting the alignment of screws during subsequent assembly. Moreover, the rigid clamping of the clamping plates can easily scratch the surface of the metal tube, thus affecting the subsequent painting effect. Therefore, a drilling device for furniture processing is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a drilling device for furniture processing. It offers the advantage of supporting the non-drilling areas of metal tubes, solving the problem of clamps generating compressive stress on the metal tube surface, causing stress concentration and resulting in surface depressions. For thin-walled or large-diameter tubes, this can cause the tube's cross-section to be compressed from a circle to an ellipse. Furthermore, as the drill moves downwards, axial force exerts downward pressure on the drilling location, causing the tube around the hole to deform. This deformation leads to misalignment between the original drilling marks and the actual structural reference of the tube, resulting in misaligned screws during subsequent assembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for furniture processing, comprising two mounting platforms disposed on the drilling device and symmetrically distributed thereon, wherein each of the two mounting platforms is provided with a fixing structure; The fixing structure includes a positioning component for positioning the metal tube, and the positioning component is set on the mounting platform. The mounting platform is provided with a connecting component for driving the positioning component to move in the direction of the metal tube. An electric push rod for controlling the connecting component is fixedly installed on the mounting platform, and the telescopic end of the electric push rod is connected to the connecting component. The positioning component includes an F-type bracket that is slidably connected to the mounting platform. A rubber roller is fixedly installed on the side of the F-type bracket near the metal tube. An anti-detachment base is fixedly installed at the end of the F-type bracket, and the anti-detachment base is connected to the connector. The connector includes a connecting ring disposed on one side of the mounting platform, and the telescopic end of the electric push rod is fixedly connected to the connecting ring. A connecting seat is fixedly installed on the connecting ring, and a connecting rod is hinged to the connecting seat and the anti-detachment base. A limiting groove is provided on the mounting platform, and the end of the F-type bracket passes through the limiting groove, with the end of the F-type bracket slidably connected to the limiting groove.

[0006] Furthermore, the number of positioning components, connecting seats, and connecting rods are all six, and they are symmetrically distributed around the central axis of the mounting platform. The mounting platform is provided with a tube slot to facilitate the passage of metal tubes.

[0007] Furthermore, the mounting platform has three mounting slots, and the included angle between two adjacent mounting slots is 120 degrees. The number of electric push rods is the same as the number of mounting slots, and the electric push rods are fixedly connected to the mounting slots.

[0008] Furthermore, three guide rods are fixedly installed on the connecting ring, which are symmetrically distributed around the central axis, and one end of each guide rod passes through the mounting platform.

[0009] Furthermore, the mounting platform has three guide holes, and the included angle between two adjacent mounting slots is 120 degrees. One end of the guide rod passes through the guide hole, and the guide rod is slidably connected to the guide hole.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This drilling device for furniture processing uses the rubber roller of the positioning component to flexibly contact the metal tube, which can buffer the clamping pressure and prevent the surface of the metal tube from being dented due to rigid extrusion. At the same time, multiple sets of F-type brackets work together to clamp and disperse stress, preventing the cross-section of thin-walled tubes or large-diameter tubes from being pressed from a circle to an ellipse. The F-type brackets are slidably connected to the limiting groove of the mounting platform, which restricts the movement trajectory of the F-type brackets, prevents the positioning component from shifting, and ensures that the drilling mark is aligned with the tube body structural reference. 2. The drilling device for furniture processing has six positioning parts, six connecting seats, and six connecting rods, which are symmetrically distributed along the central axis of the mounting platform. It can apply uniform clamping force to the metal tube from six directions, further improving clamping stability and completely avoiding deformation caused by local stress concentration. The tube placement groove of the mounting platform provides a dedicated tube passage for the metal tube, which can quickly position the metal tube to the processing position without repeated adjustments. 3. The drilling device for furniture processing has three mounting slots with an included angle of 120 degrees on the mounting table, so that the three electric push rods are distributed in an equilateral triangle. This layout ensures that the electric push rods output power to the connecting ring symmetrically, avoids the offset of the connecting parts, and ensures that all positioning parts clamp the metal tube synchronously and evenly. In addition, one end of the guide rod passes through the mounting table, which can forcibly restrict the movement direction of the connecting ring and prevent the connecting ring from offset radially.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: Please refer to Figure 1-5 In this embodiment, a drilling device for furniture processing includes two mounting platforms 1 that are symmetrically distributed on the drilling device, and each mounting platform 1 is provided with a fixing structure 2.

[0015] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the fixing structure 2 includes a positioning member 21 for positioning the metal tube, and the positioning member 21 is set on the mounting platform 1. The mounting platform 1 is provided with a connecting member 22 for driving the positioning member 21 to move in the direction of the metal tube. An electric push rod 23 for controlling the connecting member 22 is fixedly installed on the mounting platform 1, and the telescopic end of the electric push rod 23 is connected to the connecting member 22. The positioning component 21 includes an F-type bracket 211 that is slidably connected to the mounting platform 1. A rubber roller 212 is fixedly installed on the side of the F-type bracket 211 near the metal tube. An anti-detachment base 213 is fixedly installed at the end of the F-type bracket 211, and the anti-detachment base 213 is connected to the connector 22. The connector 22 includes a connecting ring 221 disposed on one side of the mounting platform 1, and the telescopic end of the electric push rod 23 is fixedly connected to the connecting ring 221. A connecting seat 222 is fixedly installed on the connecting ring 221, and a connecting rod 223 is hinged to the connecting seat 222 and the anti-detachment base 213. A limiting groove 11 is provided on the mounting platform 1, and the end of the F-type bracket 211 passes through the limiting groove 11, and the end of the F-type bracket 211 is slidably connected to the limiting groove 11.

[0016] The mounting platform 1 has three mounting slots 12, and the included angle between two adjacent mounting slots 12 is 120 degrees. The number of electric push rods 23 is the same as the number of mounting slots 12. The electric push rods 23 are fixedly connected to the mounting slots 12. The mounting platform 1 has three mounting slots 12 with an included angle of 120 degrees, and the number of electric push rods 23 matches the number of mounting slots 12, so that the three electric push rods 23 are distributed in an equilateral triangle. This layout ensures that the power output of the electric push rods 23 to the connecting ring 221 is symmetrical, avoids the offset of the connecting parts 22, and ensures that all positioning parts 21 clamp the metal tube synchronously and evenly.

[0017] In addition, three guide rods 224 are fixedly installed on the connecting ring 221, which are symmetrically distributed around the central axis. One end of the guide rod 224 passes through the mounting platform 1. The three guide rods 224 fixed on the connecting ring 221 and symmetrically distributed around the central axis, with one end of the guide rod 224 passing through the mounting platform 1, can forcibly restrict the movement direction of the connecting ring 221, prevent the connecting ring 221 from radially deviating, ensure the precise transmission of the connecting piece 22, and ensure that the positioning piece 21 can accurately contact and clamp the metal tube.

[0018] It should be noted that the mounting platform 1 has three guide holes 13, and the included angle between two adjacent mounting slots 12 is 120 degrees. One end of the guide rod 224 passes through the guide hole 13, and the guide rod 224 is slidably connected to the guide hole 13. The mounting platform 1 has three guide holes 13 with an included angle of 120 degrees, and the guide rod 224 is slidably engaged with the guide hole 13. On the one hand, the guide hole 13 further regulates the sliding path of the guide rod 224 and eliminates shaking. On the other hand, the matching structure between the guide hole 13 and the guide rod 224 can reduce sliding friction, ensure the smooth and stable movement of the connecting ring 221, and ultimately improve the clamping accuracy and stability of the positioning component 21.

[0019] Using the above technical solution, the electric push rod 23 is activated, and its telescopic end extends outward, pushing the connecting ring 221 fixedly connected to it to move towards the mounting platform 1. When the connecting ring 221 moves, it drives the connecting seat 222 fixed on it to move synchronously. The connecting seat 222 squeezes the anti-detachment base 213 through the hinged connecting rod 223. The anti-detachment base 213 drives the F-type bracket 211 to slide along the limiting groove 11 of the mounting platform 1, so that the F-type bracket 211 gets close to the metal tube until the rubber roller 212 on the F-type bracket 211 makes flexible contact with the surface of the metal tube and applies uniform pressure. The metal tube is stably clamped by multiple sets of positioning parts 21.

[0020] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, the number of positioning components 21, connecting seats 222 and connecting rods 223 are all six, and they are symmetrically distributed around the central axis of the mounting platform 1. The mounting platform 1 is provided with a tube slot 14 to facilitate the passage of metal tubes.

[0021] Using the above technical solution, six positioning components 21, six connecting seats 222, and six connecting rods 223 are provided and symmetrically distributed along the central axis of the mounting platform 1. This allows for the application of uniform clamping force to the metal tube from six directions, further improving clamping stability and completely avoiding deformation caused by local stress concentration. The tube placement groove 14 of the mounting platform 1 provides a dedicated tube passage for the metal tube, allowing the metal tube to be quickly positioned in the processing position without repeated adjustments, significantly improving feeding efficiency.

[0022] The working principle of the above embodiments is as follows: When using this drilling device for furniture processing, the metal tube to be drilled is passed through the tube slots 14 on the two mounting platforms 1, so that the drilling mark on the metal tube is aligned with the bottom of the drill bit to complete the initial positioning. When the electric push rod 23 is activated, its telescopic end extends outward, pushing the connecting ring 221, which is fixedly connected to it, to move towards the mounting platform 1. When the connecting ring 221 moves, it drives the connecting seat 222 fixed on it to move synchronously. The connecting seat 222 presses the anti-detachment base 213 through the hinged connecting rod 223. The anti-detachment base 213 drives the F-type bracket 211 to slide along the limiting groove 11 of the mounting platform 1, so that the F-type bracket 211 gets close to the metal tube until the rubber roller 212 on the F-type bracket 211 makes flexible contact with the surface of the metal tube and applies uniform pressure, and the metal tube is stably clamped by multiple sets of positioning parts 21. The drill bit descends and drills a hole at the marked position on the metal tube. After drilling is completed, the telescopic end of the electric push rod 23 retracts, and through the connector 22, it drives the positioning piece 21 away from the metal tube along the limiting groove 11, releasing the clamp. Finally, the drilled metal tube is taken out from the tube placement groove 14, completing a single processing operation.
