Description

Technical Field

[0001] This utility model relates to the technical field of metal parts drilling equipment, and specifically discloses a high-precision metal parts drilling equipment. Background Technology

[0002] In the field of metal processing, drilling holes in metal parts is a common and crucial process, as the drilling accuracy directly affects the assembly performance of the parts and the overall product quality. Currently, metal part drilling equipment on the market suffers from numerous problems in practical applications. Existing drilling equipment mostly uses a single drilling tool for operation. When multiple holes need to be machined on a part, the operator needs to repeatedly adjust the position of the part or the drilling angle of the tool. This not only makes the operation process cumbersome and consumes a lot of time, reducing production efficiency, but also easily causes positioning errors during multiple adjustments, making it difficult to guarantee the accuracy of the holes. Especially for precision parts with high precision requirements, such errors may directly lead to the scrapping of the parts. Meanwhile, the drilling process generates a large amount of metal shavings. Existing equipment lacks an effective shavings handling mechanism, and the shavings easily accumulate on the worktable or component surface. This not only affects the smooth progress of subsequent drilling operations but may also cause scratches on the machined holes during component movement or tool operation, further affecting drilling accuracy. Therefore, a high-precision metal component drilling device is needed to solve the above problems. Utility Model Content

[0003] This utility model proposes a high-precision metal parts drilling equipment. The centering positioning mechanism accurately centers the parts through a V-groove positioning plate and a limiting plate to prevent upward movement. Combined with the drilling tool moving from bottom to top, the debris falls off naturally. This double protection greatly improves the drilling accuracy. The drilling mechanism uses gear transmission to realize the synchronous rotation of multiple tools, eliminating repeated adjustment steps and significantly improving production efficiency while further improving accuracy.

[0004] This utility model is implemented as follows: a high-precision metal parts drilling device includes a support, and a drilling mechanism and a centering positioning mechanism are arranged above the support. The drilling mechanism includes a mounting frame disposed above the bracket. A motor is installed inside the mounting frame. A drive gear is fixedly connected to the output end of the motor. Multiple driven gears are meshed with the outer wall of the drive gear. A drive shaft passing through the mounting frame is fixedly connected to the upper ends of the multiple driven gears and the drive gear. A drilling tool is installed on the upper end of the multiple drive shafts. The centering positioning mechanism includes a support plate disposed above the bracket. Multiple evenly distributed mounting plates are fixedly connected to the upper end of the support plate. First electric push rods are installed on the outer walls of the multiple mounting plates. The output ends of the multiple first electric push rods pass through the mounting plates and are fixedly connected to positioning plates with V-grooves. Limiting plates are fixedly connected to the upper ends of the multiple positioning plates.

[0005] As a preferred embodiment of the high-precision metal parts drilling equipment of this utility model, the lower end of the bracket is equipped with a second electric push rod whose output end is fixedly connected to the mounting bracket.

[0006] As a preferred embodiment of the high-precision metal parts drilling equipment of this utility model, the upper end of the mounting frame is equipped with a conical disc that is sleeved on the outer wall of multiple drive shafts through multiple through holes.

[0007] As a preferred embodiment of the high-precision metal parts drilling equipment of this utility model, the lower end of the mounting bracket is fixedly connected to two symmetrically distributed first limiting shafts, and the lower ends of the two first limiting shafts pass through the bracket and are slidably connected to the bracket.

[0008] As a preferred embodiment of the high-precision metal parts drilling equipment of this utility model, the outer walls of the plurality of positioning plates are all fixedly connected with second limiting rods, and the output ends of the plurality of second limiting rods all penetrate through the support plate and are movably connected to the support plate.

[0009] In a preferred embodiment of this high-precision metal parts drilling device, the diameter of the conical disc is larger than the diameter of the mounting bracket.

[0010] As a preferred embodiment of the high-precision metal parts drilling equipment of this utility model, a fixing plate is fixedly connected between the support plate and the bracket, and a control panel and controller are installed at the rear end of the fixing plate.

[0011] The beneficial effects of this utility model are: (1) In the centering positioning mechanism, multiple positioning plates with V-grooves approach the parts synchronously under the drive of the first electric push rod. The V-grooves can adapt to parts of different shapes and achieve precise centering positioning. At the same time, the limiting plate at the top of the positioning plate limits the parts from above, which can effectively prevent the parts from moving upward during drilling, thus initially improving the drilling accuracy. Since the centering positioning mechanism is located above the drilling mechanism, the drilling tool adopts a bottom-up movement method for drilling. The generated debris will fall directly due to gravity, avoiding the accumulation of debris in the drilling area or scratching the processed hole. This reduces the factors affecting the drilling accuracy from the source and further ensures the accuracy of hole processing. (2) The drilling efficiency is significantly improved. The drilling mechanism drives the drive gear to rotate through the motor, which in turn meshes with and drives multiple driven gears, so that all drive shafts and drilling tools rotate synchronously. Multiple drilling tools can drill holes in different positions of parts at the same time, realizing multi-station synchronous operation. There is no need to repeatedly adjust the position of parts or tools, which further improves the drilling accuracy, reduces the operation steps and working time, and significantly improves the production efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-4 A high-precision metal parts drilling device includes a support 1, with a drilling mechanism and a centering positioning mechanism arranged above the support 1. The drilling mechanism includes a mounting frame 9 mounted above the bracket 1. A motor 10 is installed inside the mounting frame 9. A drive gear 11 is fixedly connected to the output end of the motor 10. Multiple driven gears 12 are meshed with the outer wall of the drive gear 11. A drive shaft 13 passing through the mounting frame 9 is fixedly connected to the upper ends of the multiple driven gears 12 and the drive gear 11. A drilling tool 14 is installed on the upper end of the multiple drive shafts 13. The centering positioning mechanism includes a support plate 3 set above the bracket 1. Multiple evenly distributed mounting plates 4 are fixedly connected to the upper end of the support plate 3. First electric push rods 5 are installed on the outer walls of the multiple mounting plates 4. The output ends of the multiple first electric push rods 5 pass through the mounting plates 4 and are fixedly connected to positioning plates 6 with V-grooves. Limiting plates 7 are fixedly connected to the upper ends of the multiple positioning plates 6.

[0020] In this embodiment: During operation, the metal part to be drilled is first placed on the support plate 3. Then, the centering positioning mechanism is activated, and the first electric actuators 5 on multiple mounting plates 4 extend and retract synchronously, pushing the positioning plate 6 with V-grooves closer to the part. Due to the V-groove design, it can adapt to parts of different shapes, and the multiple positioning plates 6 work together to accurately center and position the part. At the same time, the limiting plate 7 at the upper end of the positioning plate 6 can limit the part from above, preventing the part from moving upwards during the drilling process. After positioning is completed, the drilling mechanism begins operation. Motor 10 starts, its output driving the drive gear 11 to rotate. The drive gear 11 meshes with multiple driven gears 12, thereby driving all drive shafts 13 to rotate synchronously. The drilling tool 14, mounted on the upper end of the drive shaft 13, rotates at high speed accordingly. The mounting bracket 9 moves upwards as a whole, causing the rotating drilling tool 14 to contact the component and perform the drilling operation. Multiple drilling tools 14 can simultaneously drill holes at different positions on the component, achieving multi-station synchronous drilling without repeated position adjustments. During the drilling process, because the centering positioning mechanism is located above the drilling mechanism, the drilling tool 14 moves from bottom to top to drill, and debris falls directly due to gravity, preventing accumulation at the drilling site and affecting drilling accuracy.

[0021] As a technical optimization of this utility model, a second electric push rod 8 with its output end fixedly connected to the mounting frame 9 is installed at the lower end of the bracket 1.

[0022] In this embodiment, the mounting bracket 9 can be moved by the second electric actuator 8.

[0023] As a technical optimization of this utility model, a conical disk 15 is installed on the upper end of the mounting bracket 9, which is sleeved on the outer wall of multiple drive shafts 13 through multiple through holes.

[0024] In this embodiment, the conical disc 15 can guide the falling debris and prevent it from accumulating above the mounting frame 9.

[0025] As a technical optimization of this utility model, the lower end of the mounting bracket 9 is fixedly connected to two symmetrically distributed first limiting shafts 17, and the lower ends of the two first limiting shafts 17 pass through the bracket 1 and are slidably connected to the bracket 1.

[0026] In this embodiment, the mounting bracket 9 can be moved stably via the first limiting shaft 17.

[0027] As a technical optimization of this utility model, the outer walls of multiple positioning plates 6 are all fixedly connected with second limiting rods 16, and the output ends of multiple second limiting rods 16 all penetrate through the support plate 3 and are movably connected to the support plate 3.

[0028] In this embodiment, the use of multiple second limiting rods 16 facilitates the stable movement of multiple positioning plates 6.

[0029] As a technical optimization of this utility model, the diameter of the conical disk 15 is larger than the diameter of the mounting bracket 9.

[0030] In this embodiment, the larger diameter conical disk 15 can cover the mounting frame 9 and a larger area around it, forming an effective protective barrier. This reduces the amount of debris splashing onto key components such as the motor 10, drive gear 11, and driven gear 12 inside the mounting frame 9, preventing these components from being affected by debris accumulation or impact, thereby ensuring the stable operation of the drilling mechanism.

[0031] As a technical optimization of this utility model, a fixing plate 2 is fixedly connected between the support plate 3 and the bracket 1, and a control panel and controller are installed at the rear end of the fixing plate 2.

[0032] In this embodiment, the operator can intuitively set drilling parameters (such as drilling depth, tool speed, etc.) and monitor the equipment's operating status through the control panel. When the equipment malfunctions, the controller can respond promptly and issue prompts through the control panel, facilitating quick handling by the operator. The combination of these two mechanisms makes equipment operation more convenient and automated, effectively improving the accuracy and reliability of equipment operation and ensuring that the entire drilling process proceeds in an orderly manner according to the preset program.

[0033] The working principle and usage process of this utility model are as follows: During operation, the metal part to be drilled is first placed on the support plate 3. Then, the centering positioning mechanism is activated, and the first electric push rods 5 on multiple mounting plates 4 extend and retract synchronously, pushing the positioning plate 6 with V-grooves closer to the part. Due to the V-groove design, it can adapt to parts of different shapes, and the multiple positioning plates 6 work together to accurately center and position the part. At the same time, the limiting plate 7 at the upper end of the positioning plate 6 can limit the part from above, preventing the part from moving upwards during the drilling process. After positioning is completed, the drilling mechanism begins operation. Motor 10 starts, its output driving the drive gear 11 to rotate. The drive gear 11 meshes with multiple driven gears 12, thereby driving all drive shafts 13 to rotate synchronously. The drilling tool 14, mounted on the upper end of the drive shaft 13, rotates at high speed accordingly. The second electric actuator 8 drives the mounting bracket 9 to move upwards, causing the rotating drilling tool 14 to contact the component and perform the drilling operation. Multiple drilling tools 14 can simultaneously drill holes at different positions on the component, achieving multi-station synchronous drilling without repeated position adjustments. During drilling, because the centering positioning mechanism is located above the drilling mechanism, the drilling tool 14 moves from bottom to top, and debris falls directly due to gravity, preventing accumulation at the drilling site and affecting drilling accuracy.
