Description

Technical Field

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

[0002] A hinge is a mechanical device used to connect two solid objects (such as doors, windows, cabinets, etc.) and allow relative rotation between them. It is a common hardware accessory in daily life, widely used in construction, furniture, industrial equipment, and other fields. Its core function is to enable the opening, closing, rotation, or folding of objects. Hinge manufacturing is the process of transforming raw metal materials (such as iron, stainless steel, aluminum alloy, copper, etc.) into hinges with specific shapes and functions through a series of processes. During hinge manufacturing, the lack of a high-precision guiding structure in the hinge positioning device makes dynamic correction impossible during automated drilling. Operators must frequently interrupt the processing flow to manually fine-tune the hinge's axial position to compensate for positioning errors. This process not only increases the processing time per piece, but also, due to the lack of quantitative control over parameters such as operating force and dwell time during manual adjustment, causes non-normal distribution fluctuations in the hole position axis offset within the same batch of products, reducing the hinge's pass rate.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202322141589.4, application date 2023-08-10) provides a drilling positioning mechanism for hinge processing, including a processing platform and a drilling machine; a square frame is fixedly connected to the top of the processing platform, and a positioning component is provided on the inner wall of the square frame. The positioning component includes a long rod and two sets of short rods, with the two sets of short rods slidably connected to both sides of the long rod, and a bidirectional screw is provided inside the long rod; the beneficial effects of this drilling positioning mechanism for hinge processing are as follows: first, the handle and the rotary handle are rotated respectively to push the long rod and the short rods to the size of the hinge, then the hinge is placed on the inner wall of the positioning component, and then the drilling machine is operated to perform the drilling operation. This solves the problem that existing hinge drilling devices cannot accurately position and fix the hinge, and are prone to drilling deviation during the drilling process, thus meeting the needs of users.

[0004] Rapid positioning ensures the continuity and smoothness of the production process. As a key starting point of the entire processing flow, rapid positioning allows subsequent steps such as drilling and inspection to be closely connected, avoiding process interruptions caused by positioning delays, thereby optimizing the overall production rhythm and improving production efficiency. However, the aforementioned device cannot achieve rapid positioning of the hinges during use, resulting in reduced output per unit time and causing significant positioning errors in the hinges, which reduces product quality and lowers the overall production efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to provide a positioning drilling device for hinge processing, in order to solve the problems mentioned in the background art, such as the inability to quickly position the hinge, which leads to reduced output per unit time, large positioning errors in the hinge, reduced product quality, and reduced overall production efficiency of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning hinge drilling device, comprising a base, a worktable fixedly connected to the upper surface of the base, and a drilling assembly fixedly connected to the end of the upper surface of the base away from the worktable; a sliding groove is provided inside the base, and a fixing block is fixedly connected to the end of the upper surface of the base near the worktable; a lubricant tank is fixedly connected to the end of the upper surface of the base near the drilling assembly, and a fixed shaft is provided inside the base through a reciprocating sliding structure; a support frame is fixedly connected to the surface of the fixed shaft, and the support frame is rotatably disposed at the lower end of the base; a clamping plate is slidably connected to the surface of the sliding groove, and the clamping plates are symmetrically distributed about the center of the base; and a fixing plate is fixedly connected to the lower surface of the base away from the fixed shaft.

[0007] Preferably, a motor is fixedly connected to one end of the lower surface of the base near the fixed plate, and a rotating shaft is fixedly connected to the output end of the motor, and the rotating shaft is rotatably disposed inside the base.

[0008] Preferably, both the fixed shaft surface and the rotating shaft surface are fitted with belts, and the reciprocating sliding structure includes a limiting rod fixedly connected to the surface of the fixed plate.

[0009] Preferably, one end of the connecting rod is slidably connected to the surface of the support frame, and the other end of the connecting rod is slidably connected to the clamping plate, and the limiting rod is slidably connected through the clamping plate.

[0010] Preferably, a drive shaft is rotatably mounted inside the fixed block, a rotating frame is fixedly connected to the surface of the rotating shaft, and one end of a connecting frame is slidably connected to the surface of the rotating frame.

[0011] Preferably, the other end of the connecting frame is slidably connected to the drive shaft, and the drive shaft is rotatably mounted on the upper end of the base.

[0012] Preferably, a nozzle is fixedly connected to the surface of the drive shaft, and one end of a connecting pipe is fixedly connected to the upper end of the nozzle, while the other end of the connecting pipe is fixedly connected to the lubricant tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the drilling device for positioning hinge processing adopts a novel structural design, the specific details of which are as follows: This positioning drilling device for hinge processing achieves rapid positioning of hinges through a clamping plate and sliding groove, shortening the time required for positioning each hinge. This allows for the processing of more hinges per unit time, improving overall production efficiency. At the same time, it prevents hinge displacement during drilling, ensuring that each hole is in the precise position.

[0014] Furthermore, this ensures that the hinges will not shift at all during the drilling process due to the impact force or vibration of the drill bit, thus guaranteeing that each drill hole will be precisely positioned as required by the design.

[0015] This positioning hinge drilling device, through its lubricant tank and connecting pipes, effectively reduces the friction between the drill bit and the hinge, decreases the heat generated by friction, thereby slowing down the wear rate of the drill bit. At the same time, it ensures the accuracy and surface quality of the drilling, reduces the frequency of drill bit replacements due to excessive wear, and improves production efficiency.

[0016] Furthermore, it enables drilling operations to be carried out without interruption, greatly improving production efficiency, shortening processing time, increasing capacity, and enhancing the reliability and stability of equipment, thus ensuring the continuity of production.

[0017] (3) The positioning hinge drilling device ensures stable operation of the device through the fixed plate and the limiting rod, which makes the stress on each component more uniform and stable, avoids component fatigue damage caused by frequent vibration and impact, and significantly extends its service life, reducing equipment maintenance costs and downtime.

[0025] 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.

[0026] Example 1: The fixed plate 19, sliding groove 9, and fixed block 12 improve the stability of the device during operation, making the stress on each component more uniform and stable. Figure 1 As shown: It includes a base 1, a workbench 2 fixedly connected to the upper surface of the base 1, and a drilling assembly 3 fixedly connected to the end of the upper surface of the base 1 away from the workbench 2. A sliding groove 9 is provided inside the base 1. A fixing block 12 is fixedly connected to the end of the upper surface of the base 1 near the workbench 2. A lubricant tank 15 is fixedly connected to the end of the upper surface of the base 1 near the drilling assembly 3. A fixed shaft 10 is provided inside the base 1 through a reciprocating sliding structure. A support frame 6 is fixedly connected to the surface of the fixed shaft 10. The support frame 6 is rotatably set at the lower end of the base 1. A clamping plate 8 is slidably connected to the surface of the sliding groove 9. The clamping plates 8 are symmetrically distributed about the center of the base 1. A fixing plate 19 is fixedly connected to the lower surface of the base 1 away from the fixed shaft 10.

[0027] The worker places the hinge to be processed on the upper part of the workbench 2, and then starts the motor 4. The motor 4 drives the clamping plate 8 to slide on the surface of the sliding groove 9 (e.g., Figure 1 As shown), and fixes the hinges to be processed on the upper end of the workbench 2, shortening the time required for positioning each hinge, thereby processing more hinges per unit time and improving overall production efficiency. At the same time, the lubricant inside the lubricant tank 15 is sprayed out from the nozzle 17 through the connecting pipe 16 (as shown). Figure 6 As shown), spraying is applied to the processing area to reduce friction and heat generation, thereby slowing down the wear rate of the drill bit, ensuring drilling accuracy and surface quality. Furthermore, the fixed plate 19 and limiting rod 18 ensure stable operation of the device, resulting in more uniform and stable stress distribution across the components (e.g., ...). Figure 2 and Figure 3As shown in the figure, it avoids component fatigue damage caused by frequent vibration and impact, and can significantly extend its service life, reduce equipment maintenance costs and downtime.

[0028] In Example 2, unlike Example 1, the motor 4, connecting rod 7, and clamping plate 8 ensure that the hinge does not shift at all during drilling due to the impact force or vibration of the drill bit, thus guaranteeing that each drill hole falls precisely in the designed position. Figures 2-3 As shown: A motor 4 is fixedly connected to one end of the lower surface of the base 1 near the fixed plate 19, and a rotating shaft 5 is fixedly connected to the output end of the motor 4. The rotating shaft 5 is rotatably disposed inside the base 1. A belt is sleeved and connected to both the surface of the fixed shaft 10 and the surface of the rotating shaft 5. The reciprocating sliding structure includes a limiting rod 18 fixedly connected to the surface of the fixed plate 19. One end of a connecting rod 7 is slidably connected to the surface of the support frame 6, and a clamping plate 8 is slidably connected to the other end of the connecting rod 7. The limiting rod 18 is slidably connected through the clamping plate 8.

[0029] When the motor 4 is working, it drives the output shaft 5 to rotate inside the base 1 (e.g., Figure 3 As shown), belts are fitted on both the rotating shaft 5 and the fixed shaft 10. Through belt drive, the motor 4 drives the fixed shaft 10 to rotate inside the base 1 when it is working (as shown). Figure 5 As shown in the figure, the fixed shaft 10 drives the surface support frame 6 to rotate, so that the support frame 6 pulls the surface connecting rod 7 to slide at the lower end of the base 1. At the same time, the connecting rod 7 pulls the clamping plate 8 at the other end to slide on the surface of the limiting rod 18, thereby quickly positioning the hinges on the surface of the worktable 2, shortening the time required for positioning each hinge, so that more hinges can be processed per unit time, improving the overall production efficiency, and preventing the hinges from shifting during drilling, ensuring that each hole is in the precise position.

[0030] In Example 3, unlike Example 2, the use of the rotating shaft 5, transmission shaft 14, and lubricant tank 15 enables uninterrupted drilling operations, significantly improving production efficiency, shortening processing time, and increasing capacity. Figures 4-6 As shown: A drive shaft 14 is rotatably mounted inside the fixed block 12. A rotating frame 11 is fixedly connected to the surface of the rotating shaft 5. One end of a connecting frame 13 is slidably connected to the surface of the rotating frame 11. The other end of the connecting frame 13 is slidably connected to the drive shaft 14. The drive shaft 14 is rotatably mounted on the upper end of the base 1. A nozzle 17 is fixedly connected to the surface of the drive shaft 14. One end of a connecting pipe 16 is fixedly connected to the upper end of the nozzle 17. The other end of the connecting pipe 16 is fixedly connected to a lubricant tank 15.

[0031] As the motor 4 drives the rotating shaft 5 to rotate inside the base 1, it causes the upper end of the rotating frame 11 on the surface of the base 1 to rotate, and the rotating frame 11 causes the connecting frame 13 on the surface to slide inside the rotating frame 11 (e.g., Figure 5 As shown), with the rotation of the rotating frame 11, the connecting frame 13 drives the transmission shaft 14 at the other end to rotate inside the fixed block 12, while the transmission shaft 14 drives the nozzle 17 on the surface to slide back and forth (as shown). Figure 6 As shown in the figure, the lubricant tank 15, through the connecting pipe 16 and the nozzle 17, allows the lubricant inside the lubricant tank 15 to be evenly sprayed on the working area of ​​the device, forming a lubricating film on the contact surface, reducing friction and heat generation, thereby slowing down the wear rate of the drill bit, ensuring the accuracy and surface quality of the drilling, reducing the number of times the drill bit needs to be replaced due to excessive wear, improving production efficiency, improving the reliability and stability of the equipment, and ensuring the continuity of production.

[0032] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
