Description

Technical Field

[0001] This utility model belongs to the technical field of spindle positioning devices, specifically relating to a high-precision spindle positioning device for a C-type moving column six-axis machine tool. Background Technology

[0002] The high-precision spindle positioning device is one of the core components of a C-type moving column six-axis machine tool. Its main function is to ensure that the spindle can be accurately positioned during machining, thereby guaranteeing machining accuracy and quality. This device typically consists of a spindle, a positioning system, and related support structures. Through complex mechanical and electronic control methods, it achieves stable operation and precise position control of the spindle in multi-axis linkage machining to meet the stringent accuracy requirements of machining complex parts.

[0003] However, existing high-precision spindle positioning devices for C-type moving column six-axis machine tools have some shortcomings. On the one hand, the method of fixing the tool head is relatively cumbersome, and the disassembly and assembly process is time-consuming and labor-intensive. This not only reduces the efficiency of machine tool maintenance and tool replacement, but may also lead to the tool head not being firmly fixed due to improper operation, thereby affecting the machining accuracy and safe operation of the machine tool. On the other hand, during the spindle rotation process, there is a lack of real-time and accurate monitoring methods for the tool head position, making it impossible to detect small deviations in the tool head position in time. This makes it difficult to ensure the stability of the spindle rotation process, which can easily lead to the accumulation of machining errors, affecting the dimensional accuracy and surface quality of the machined parts, and failing to meet the requirements of high-precision machining applications.

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.

[0021] Example 1

[0022] Please see Figure 1-5This utility model provides the following technical solution: a high-precision spindle positioning device for a C-type moving column six-axis machine tool, including a machine base 1, an mounting plate 6 on the upper side of the machine base 1, a C-type moving column six-axis machine tool body 2 on the side of the mounting plate 6, an mounting head 5 on the lower end of the C-type moving column six-axis machine tool body 2, a spindle 8 on the side of the mounting head 5, a flange 10 on the other end of the spindle 8, a tool head mounting and fixing mechanism 3 on the side of the flange 10, and a bolt 9 for fixing the flange 10 to the tool head mounting and fixing mechanism 3. A spindle positioning monitoring mechanism 4 is provided on the side of the tool head mounting and fixing mechanism 3.

[0023] Specifically, the cutter head mounting and fixing mechanism 3 includes a gear box 31, a motor 32, a driving gear 33, a driven gear 34, a rotating shaft 35, a positioning plate 36, a mounting post 37, a fixing component 38, and a mounting sleeve 310. The gear box 31 is located on the side of the flange 10. The motor 32 is housed inside the gear box 31. The driving gear 33 is located at the output end of the motor 32. The driven gear 34 is meshed with the side of the driving gear 33. The rotating shaft 35 is located on the side of the driven gear 34. The rotating shaft 35 is rotatably connected to the gear box 31 via a bearing. The positioning plate 36 is located at the other end of the rotating shaft 35. The mounting post 37 is located on the side of the positioning plate 36. The fixing component 38 is located inside the side of the mounting post 37. The mounting sleeve 310 is located at the other end of the cutter head body 7.

[0024] By adopting the above technical solution, the tool head can be quickly installed and fixed. The motor 32 drives the rotating shaft 35 to rotate through the driving gear 33 and the driven gear 34, which in turn causes the positioning plate 36 and the mounting column 37 to rotate, thereby realizing the quick positioning and fixing of the tool head body 7 and greatly improving the installation efficiency of the tool head.

[0025] Specifically, the cutter head mounting and fixing mechanism 3 also includes a socket 39, a tie rod 311, and a nut 312. The mounting post 37 and the mounting sleeve 310 are fixedly connected by the tie rod 311. The mounting post 37 has a socket 39 inside that corresponds to the tie rod 311. Nuts 312 are threaded onto the two ends of the tie rod 311.

[0026] By adopting the above technical solution, the connection stability between the cutter head body 7 and the mounting post 37 is further enhanced. The pull screw 311 passes through the mounting post 37 and the mounting sleeve 310, and the fastening effect of the nut 312 ensures that the cutter head body 7 will not loosen during the processing, thus improving the reliability of the processing.

[0027] Specifically, the fixing component 38 includes a fixing pin 381, a limiting plate 382, ​​a circular groove 383, a spring 384, and a fixing hole 385.

The other end of the spring 384 is provided with a limiting plate 382, ​​and the other end of the limiting plate 382 is provided with a fixing pin 381. The mounting sleeve 310 has a fixing hole 385 corresponding to the fixing pin 381 on its side.

[0028] By adopting the above technical solution, the quick fixing and release of the cutter head body 7 is realized. When the cutter head body 7 is installed in place, the fixing pin 381 is automatically inserted into the fixing hole 385 under the action of the spring 384 to ensure the stable fixing of the cutter head body 7. When it is necessary to disassemble the cutter head, simply press the fixing pin 381, and the fixing pin 381 can be withdrawn from the fixing hole 385 to achieve quick disassembly.

[0029] In this embodiment, the mounting sleeve 310 of the cutter head body 7 is first aligned with the mounting post 37. The cutter head body 7 is then fixed to the mounting post 37 by the pull screw 311 and nut 312. Then, the motor 32 is started. The motor 32 drives the rotating shaft 35 to rotate through the driving gear 33 and the driven gear 34, causing the positioning plate 36 and the mounting post 37 to rotate, thereby achieving rapid positioning and fixing of the cutter head body 7. During the processing, the fixing pin 381 in the fixing assembly 38 is automatically inserted into the fixing hole 385 under the action of the spring 384, ensuring the stable fixing of the cutter head body 7. When it is necessary to disassemble the cutter head, simply press the limit plate 382, ​​and the fixing pin 381 can be withdrawn from the fixing hole 385, achieving rapid disassembly. This design not only improves the efficiency of cutter head installation and disassembly but also ensures the stability during the processing.

An infrared sensor 45 is located at the other end of the telescopic rod 43. A controller 46 is located at the lower side of the mounting plate 6.

[0032] By adopting the above technical solution, real-time monitoring and precise control of the position of the spindle 8 are achieved. The infrared sensor 45 can monitor the position change of the positioning disk 36 in real time and transmit the monitoring signal to the controller 46. The controller 46 controls the running status of the C-type moving column six-axis machine tool body 2 according to the processed signal, thereby ensuring the precise positioning and stability of the spindle 8 during the machining process.

[0033] Specifically, the infrared sensor 45 is electrically connected to the controller 46. The controller 46 can receive and process the signals transmitted by the infrared sensor 45.

The controller 46 can control the operating status of the C-type moving column six-axis machine tool body 2 according to the processed signals, so as to achieve precise monitoring and control of the spindle 8 positioning.

[0034] By adopting the above technical solution, the positioning accuracy and reliability of the spindle 8 are further improved. The controller 46 can adjust the position of the spindle 8 in real time according to the feedback signal of the infrared sensor 45, ensuring high precision and stability in the machining process.

[0035] In this embodiment, the infrared sensor 45 is installed at the other end of the telescopic rod 43, and the position of the infrared sensor 45 is adjusted by bolt 3 44 to enable it to accurately monitor the position changes of the positioning plate 36. Then, the infrared sensor 45 is electrically connected to the controller 46 to ensure the stability of signal transmission. During the machining process, the infrared sensor 45 monitors the position changes of the positioning plate 36 in real time and transmits the monitoring signal to the controller 46. The controller 46 controls the running state of the C-type moving column six-axis machine tool body 2 according to the processed signal, thereby ensuring the precise positioning and stability of the spindle 8 during the machining process. This design not only improves the positioning accuracy of the spindle 8, but also ensures the high efficiency and high quality of the machining process.

[0037] The controller 46 in this invention is a publicly available technology, and the selected model is Arduino Mega2560.

[0038] The working principle and usage process of this utility model are as follows: When using this utility model, first align the mounting sleeve 310 of the cutter head body 7 with the mounting post 37. Then, fix the cutter head body 7 to the mounting post 37 using the pull screw 311 and nut 312. Next, start the motor 32. The motor 32 drives the rotating shaft 35 to rotate via the driving gear 33 and driven gear 34, causing the positioning plate 36 and mounting post 37 to rotate, achieving rapid positioning and fixing of the cutter head body 7. During processing, the fixing pin 381 in the fixing assembly 38 automatically inserts into the fixing hole 385 under the action of the spring 384, ensuring the stable fixing of the cutter head body 7. When it is necessary to disassemble the cutter head, simply press the limit plate 382, ​​and the fixing pin 381 will exit from the fixing hole 385, achieving rapid disassembly. This design not only… This design improves the efficiency of tool head installation and removal, and ensures stability during machining. An infrared sensor 45 is installed at the other end of the telescopic rod 43, and its position is adjusted using bolt 3 44 to accurately monitor changes in the position of the positioning disc 36. The infrared sensor 45 is then electrically connected to the controller 46 to ensure stable signal transmission. During machining, the infrared sensor 45 monitors the position changes of the positioning disc 36 in real time and transmits the monitoring signal to the controller 46. The controller 46 controls the operation of the C-type moving column six-axis machine tool body 2 based on the processed signal, thereby ensuring precise positioning and stability of the spindle 8 during machining.
