[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0025] Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.
[0026] As Figures 1 to 6 shown, the present application provides an embedded tool detection device, which is arranged on the main shaft 9 and can move with the main shaft 9. In the present application, the embedded tool detection device is not only embedded in the working space 101, but also embedded on the main shaft. It is directly arranged on the main shaft stand for installing the main shaft, can move with the main shaft and detect the tool group in the working space, thereby greatly improving the efficiency and eliminating the independent position arranged on the machine body. Moreover, by using the moving range of the main shaft, the tool group can be approached before detection to further improve the detection efficiency.
[0027] Specifically, the embedded tool detection device in the present application comprises: a second telescopic arm 31 arranged on the main shaft stand 90 and located on one side of the main shaft 9; a tool detection assembly 32 arranged on the second telescopic arm 31, the second telescopic arm 31 can drive the tool detection assembly 32 to be stored in the main shaft stand 90, and in the working state, the second telescopic arm 31 extends to the working space 101, so that the tool detection assembly 32 detects the tool group 91 in the working space 101. By the telescopic arrangement, the tool detection assembly can be stored in the main shaft stand during the workpiece machining process, and the automatic machining in the working space is not affected, thereby effectively protecting the tool detection assembly.
[0028] In the embodiment of the utility model, the second telescopic arm 31 is extended from the lower end of the main shaft support 90 to the working space 101, and is consistent with the direction of clamping workpiece of the main shaft 9. Moreover, when the second telescopic arm 31 is extended, the tool detection assembly 32 is located at one side of the workpiece and close to the tool set 91. The position and direction of the tool detection assembly 32 are set, which is beneficial to quickly positioning the position of the main shaft. After detecting the tool set, it can be understood that, since the tool directly processes the workpiece on the main shaft, the present scheme processes through the main shaft moving to the tool set, and the system needs to judge the initial position of the main shaft 9 and the position of the processing tool bit on the tool set. The second telescopic arm 31 of the present scheme is directly extended from one side of the workpiece, that is, it is located at the preset position of the main shaft 9 when it is extended, and the position is close to the workpiece, that is, the processing position, so that the detection program can be simplified.
[0029] Therefore, in the present scheme, the main shaft needs to move in the working space. Generally, there is a transverse moving assembly for transverse movement and a lifting assembly 81 for longitudinal movement. It can be understood that the main shaft support 90 of the present scheme is arranged on the lifting assembly 81, and the second telescopic arm 31 rises and falls with the main shaft support 90. Thus, the second telescopic arm 31 is simplified, that is, the second telescopic arm 31 is first moved to the position close to the tool set 91 with the main shaft support 90, and then extended, so that the required length of the second telescopic arm 31 is reduced. Moreover, the structure is more compact, the distance is shortest when the second telescopic arm 31 is extended and works, and the speed is faster, so that the efficiency is further improved.
[0030] Specifically, in the storage state, the second telescopic arm 31 is retracted into the main shaft support 90, and the main shaft support 90 has an opening communicating with the working space 101. When extended, the second telescopic arm 31 is directly extended from the opening to the working space, so that the extension distance of the second telescopic arm 31 is shortened.
[0031] Further, the second telescopic arm 31 of the present scheme can be stored, which avoids hindering the processing in the working space 101 and protects the tool detection assembly 32, so that the tool detection assembly 32 is prevented from being splashed by debris during processing. Therefore, the present scheme further provides a cover member arranged at the opening, and the opening is covered by the cover member. When the second telescopic arm 31 needs to be extended, the opening is only needed to be opened. In the present scheme, the main shaft support 90 is further provided with a cover member for covering the opening. The cover member can be a baffle 9011 which is opened by rotating or sliding.
[0032] Specifically, in this embodiment of the invention, the built-in tool detection device has the following structure: the second telescopic arm 31 includes a second mounting base 311 and a second driving member 312 connected to the second mounting base 311. The second driving member 312 is used to drive the second mounting base 311 to move vertically. In this design, the second mounting base 311 has a long strip-shaped structure, which is equivalent to a telescopic arm. Its length supports the extended tool detection component 32. It can also be configured as a sleeve-type telescopic structure to achieve the above-mentioned storage or extension.
[0033] This solution incorporates a directly mounted second mounting base 311 within the tool holder 90, which does not require excessive extension. The second mounting base 311 is preferably an integral unit, and it is slidably mounted within the tool holder 90. Specifically, a second fixed seat is provided within the inner tool holder 90, located on one side of the second mounting base 311. A slider is mounted on the second fixed seat, and a corresponding guide rail is provided on one side of the second mounting base 311, allowing the second fixed seat to slidably support the second mounting base 311. The guide rail is positioned at the second mounting base 311 to accommodate its elongated structure, thus saving space.
[0034] This solution uses a second driving component 312 to drive the second mounting base 311 to move vertically. This can be achieved using a power system such as a motor, cylinder, or hydraulic system. Alternatively, the second driving component 312 can directly move the second mounting base 311, or it can move the second mounting base 311 through a transmission component. Preferably, the second driving component 312 can be a cylinder, with its output shaft connected to the second mounting base 311. This results in a simpler and more compact structure.
[0035] Specifically, in this design, the cylinder body is mounted inside the spindle frame 90 via a mounting bracket 3112, and its output end is connected to the connecting part on the second mounting base 311.
[0036] In this embodiment of the utility model, the mounting box 30 can be directly provided on one side of the spindle frame 90, so that the above-mentioned tool detection device can be directly assembled in the mounting box 30.
[0037] In the embodiment of the utility model, the cutter detection assembly 32 is arranged on the lower side of the second mounting seat 311, the cutter detection assembly 32 has multidirectional detection head 320, the multidirectional detection head 320 at least includes first detection head 3201 and second detection head 3202 with the horizontal direction of second mounting seat 311 movement, third detection head 3203 and fourth detection head 3204 with the vertical direction of second mounting seat 311 movement, fifth detection head 3205 with the direction of first detection head 3201, second detection head 3202, third detection head 3203, fourth detection head 3204 are all perpendicular. Considering the machining center, the cutter group is generally provided with multiple cutters to realize multiple types of work and different demand machining, thus the cutter edge position and orientation on different cutters are different, the scheme is provided with multiple directional detection heads to adapt to the corresponding directional detection head according to the cutter edge on the cutter group in different orientations and different directions, and the complex environment use is satisfied. Taking the scheme as an example, the orientations of first detection head 3201 and second detection head 3202 are respectively up and down, the orientations of third detection head 3203 and fourth detection head 3204 are respectively left and right, and fifth detection head 3205 is perpendicular to up, down, left and right, and such structure can basically satisfy the range use of the whole working space.
[0038] Of course, according to the use demand, the five detection heads can also be mounted on the rotating seat 3200, so that first detection head 3201 and second detection head 3202, third detection head 3203 and fourth detection head 3204 can also rotate with the rotating seat 3200 to realize multidirectional and multi-angle detection.

Therefore, machining center also has same beneficial effect.
