[0041] See Figure 1 , Figure 2 A first linear motor 104 is provided at the top rear end of the base 101, and a second linear motor 105 is installed at the moving end of the first linear motor 104. The arrangement of the first linear motor 104 and the second linear motor 105 enables the machining center to achieve vertical and horizontal translational movements, thereby expanding the machining range and improving the flexibility and accuracy of machining.

The first linear motor 104 drives the second linear motor 105 to move up and down, and the second linear motor 105 drives the mounting plate 106 to move left and right. This double linear motor arrangement allows the machining center to move flexibly in three-dimensional space, further improving the machining range and precision.

[0043] Referring to Figure 1 , Figure 2 , Figure 1 , Figure 2 The loading assembly 1 is made of stainless steel, and the mounting frame 201, the connecting rod 202, and the storage seat 203 are made of aluminum alloy. The loading assembly 1 is made of stainless steel, which ensures the firmness and durability of the machining center. The mounting frame 201, the connecting rod 202, and the storage seat 203 are made of aluminum alloy, which not only reduces the weight but also ensures the stability and strength of the structure. This material selection makes the machining center both firm and light, improving the service life and machining efficiency.

[0044] Referring to Figure 3 , Figure 4 The output end of the second linear motor 105 is installed with the mounting plate 106, and the outer surface of the mounting plate 106 is installed with the drilling machine 107. The output end of the second linear motor 105 is installed with the mounting plate 106, and the outer surface of the mounting plate 106 is installed with the drilling machine 107. This arrangement allows the machining center to perform drilling and other machining operations, further enriching the machining functions.

[0045] Referring to Figure 1 , Figure 2 The bottom of the drilling machine 107 is provided with a plurality of mounting seats 108, and the bottom of each mounting seat 108 is installed with a plurality of drill bits. The bottom of the drilling machine 107 is provided with a plurality of mounting seats 108, and the bottom of each mounting seat 108 is installed with a plurality of drill bits. This arrangement allows the machining center to adapt to different machining requirements, improving the diversity and flexibility of machining.

[0046] Referring to Figure 1 , Figure 2 Figure 1 Figure 2 The plurality of mounting seats 108 at the bottom of the drilling machine 107 can be independently driven, and the plurality of independently driven mounting seats 108 can be driven according to the requirements of different drill bits. The plurality of mounting seats 108 at the bottom of the drilling machine 107 can be independently driven, and the plurality of independently driven mounting seats 108 can be driven according to the requirements of different drill bits. This arrangement allows the machining center to be more flexible in machining operations, improving the machining efficiency and precision, and also facilitates the replacement and management of drill bits during machining.

[0047] The implementation principle of the utility model is: firstly, the machining center starts working, the clamping mechanism 103 clamps multiple workpieces, ensures that they are stable and unmoved in the machining process, and the rotating mechanism 102 is responsible for driving these workpieces to rotate, so as to process different parts of the workpiece without replacing the tool bit, thereby improving the flexibility and efficiency of machining;

[0048] When a group of tool bits need to be replaced or checked after being used for one day, the first linear motor 104 starts working, it drives the second linear motor 105 and all components thereon, including the mounting plate 106 and the drilling machine 107, to slide to the right, this sliding action is to move the tool bit to the position of the storage seat 203, so as to be stored and detected;

[0049] Subsequently, the various tool bits at the bottom of the drilling machine 107 will enter the storage seat 203 through the storage groove 204, the storage seat 203 is arranged so that it can store and manage various tool bits, facilitate replacement and protect the tool bits from external damage;

[0050] At this time, the sensing mechanism 2 starts to play its role, the laser displacement sensor 205 in it starts to work, it penetrates through the storage seat 203 and extends into the storage groove 204, the laser displacement sensor 205 emits a laser beam through the emission head 206, for measuring the displacement and integrity of the tool bit, and the reflecting sheet 207 cooperates with the emission head 206, reflects the laser beam, helps the sensor to more accurately measure the state of the tool bit;

[0051] The working principle of the sensing mechanism 2 is based on the precise ranging function of the laser displacement sensor 205, which emits a beam of laser light through its internal emitter 206. The laser light is focused by a lens to form a small spot and is directed towards the tool bit in the receiving groove 204. When the laser beam strikes the surface of the tool bit, a portion of the light is reflected back and is received by the receiver inside the laser displacement sensor 205. The received reflected light is converted into an electrical signal and is amplified and filtered by the signal processing module to meet the requirements of subsequent processing. Since the intensity of the reflected light changes with the distance between the tool bit and the emitter, the signal processing module needs to amplify these weak signals to an appropriate level. The processed electrical signal is sent to the calculation module for analysis and calculation, which uses the triangulation method to calculate the distance between the tool bit and the emitter. By comparing the actual measurement value with the preset reference value, the wear degree or integrity of the tool bit can be determined. The final calculation result is output to indicate the status of the tool bit. If the tool bit is severely worn or has other defects, the sensing mechanism will issue an alarm or stop signal to prompt the operator to replace or repair the tool bit in time. Therefore, the sensing mechanism 2 realizes effective monitoring of the integrity of various tool bits by combining the precise ranging function of the laser displacement sensor 205 with signal processing and displacement calculation technology, thereby improving the automation level and production efficiency of the machining center and ensuring the accuracy and safety of the machining process.
