[0022] The present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Example

[0024] See also Figure 1-5 The utility model is an automated denture processing equipment, including a frame 1, a three-axis mobile platform 8 is arranged on the top of the frame 1, and the three-axis mobile platform 8 is matched with a base 6, and an electric spindle 4 is arranged at the bottom of the base 6, and the electric spindle 4 is adapted to be installed with a motor 1 7; a panel 2 is fixed on the front of the frame 1, and the panel 2 is connected to the fixture 3 through a shaft sleeve 10, and the shaft of the fixture 3 is adapted to be installed with a motor 2 11, and the motor 2 11 is fixed to the back of the panel 2; a hidden tool magazine 9 is arranged on the back of the panel 2, and the hidden tool magazine 9 includes a bottom plate 92 fixed to the back of the panel 2, a limit seat 96 fixed to the front side of the bottom plate 92, a cylinder 91 fixed to the tail of the upper side of the bottom plate 92, a tool holder 93 that moves synchronously with the telescopic end of the cylinder 91 through a connecting piece, a guide rail 94 fixed to the side of the tool holder 93, and a tool handle 95 and a tool setting instrument 97 arranged inside the tool holder 93.

[0025] Further description of the above structure is as follows:

[0026] In order to prevent the dust and cutting fluid caused by processing from affecting the accuracy of tool setting, the tool setting instrument 97 is placed on a tool seat in the tool holder 93 and moves with the tool holder 93. When changing the tool, the tool holder 93 has only two states: extending to the specified position and returning to the fixed position. Therefore, the cylinder 91 is used to push the tool holder 93 to complete the movement, and the moving position of the tool holder 93 is detected by the photoelectric switch.

[0027] The three-axis mobile platform 8 includes an X-axis linear guide seat 81 fixed to the top of the frame 1, a Y-axis linear guide seat 82 assembled on the upper part of the X-axis linear guide seat 81, and a Z-axis linear guide seat 84 adapted to the Y-axis linear guide seat 82 via a receiving seat 83. The machine base 6 is fixed to the vertical moving end of the Z-axis linear guide seat 84. The three-axis mobile platform 8 is a common drive system in current mechanical processing. The three-axis mobile platform 8 here is used to drive the multi-position movement of the electric spindle 4 to meet the processing requirements of different positions, and it is also convenient for subsequent tool changing. The specific structural composition and driving principle of the three-axis mobile platform 8 are not described here one by one.

[0028] The electric spindle 4 is located above the fixture 3, and the tapered hole at the bottom of the electric spindle 4 cooperates with the tool holder 95. Taking into account the small size of the processing object, the complex and changeable processing surface morphology, the thin wall and the high processing quality requirements, the high-speed milling processing method is adopted, which can not only meet the above requirements, but also reduce the speed of tool wear. The high-speed electric spindle 4 used here can complete the cutting operation stably and efficiently, and the tool holder 95 is directly powered by the electric spindle 4.

[0029] The electric spindle 4 includes a body and a rotating shaft, and the main body of the rotating shaft is embedded in the body. The rotating shaft is exposed to the outside and is easily affected by the outside world, which reduces the processing accuracy. The processing of materials requires lubrication and cooling of cutting fluid. The hidden installation of the rotating shaft in the digital denture processing equipment not only solves the contact problem between the cutting fluid and the rotating shaft, but also increases the aesthetics of the equipment to a certain extent. At the same time, the hidden design of the rotating shaft effectively reduces the space occupied by the equipment, facilitates the maintenance and maintenance work of the maintenance personnel on the equipment, reduces the parts that the maintenance personnel need to disassemble and install, saves maintenance time and labor costs, and improves the equipment operation efficiency.

[0030] A tool magazine door 5 is fixed to the front end of the tool holder 93, and the tool magazine door 5 is sealed with the outlet opened on the side of the panel 2, the guide rail 94 is matched with the inner guide block of the limit seat 96, and the bottom plate 92 and the side of the limit seat 96 are provided with photoelectric switches. Two photoelectric limit switches are used. When the detected object passes through the U-shaped groove, the photoelectric switch detects the signal and limits the tool magazine from leaving and returning, so as to achieve precise braking under the push of the cylinder 91. The design of the hidden tool magazine 9 can improve the space utilization and automation level of the equipment, reduce manual intervention, and improve production efficiency. At the same time, it improves the management of the tool, making the replacement and maintenance of the tool more efficient and convenient; when processing the workpiece, dust and cutting fluid cannot enter the tool magazine, so it is necessary to ensure the sealing of the tool magazine, while making the structure simple and reducing the control circuit. Therefore, a baffle can be designed at the front end of the tool holder 93 as the tool magazine door 5.

[0031] In summary, the digital denture processing equipment integrates functions such as high-precision processing, efficient cutting, and automatic tool change, and is particularly suitable for processing small, high-precision, and complex workpieces such as dentures. When in use, the denture workpiece to be processed is placed on the fixture 3, and the motor 11 drives the fixture 3 axis to clamp the workpiece. According to the processing requirements, the corresponding tool is selected through the control system, and the cylinder 91 drives the tool holder 93 to extend to the specified position. The tapered hole at the bottom of the electric spindle 4 cooperates with the selected tool handle 95 to complete the tool change operation. The control system controls the three-axis mobile platform 8 to drive the electric spindle 4 to move to multiple positions to achieve precise processing of the workpiece. During the processing, the cutting fluid lubricates and cools the workpiece to ensure the processing quality and tool life. After the processing is completed, the cylinder 91 drives the tool holder 93 to return to the fixed position, and the tool magazine door 5 is closed. The tool is cleaned, inspected, and maintained regularly to ensure the normal use of the tool and extend its service life.
