[0041] Embodiment

[0042] The embodiment provides a gantry machine tool tool detection mechanism, which refers to Figure 1 and Figure 2 As shown in the drawings, it comprises a guide rail 1, a moving seat 2, a tool detection instrument 3, a movable door 4, a fixed door 5 and a two-stage electric push rod 6. The guide rail 1 is installed on a machine tool base 7, the moving seat 2 is movably installed on the guide rail 1, so that the moving seat 2 can move along the length direction of the guide rail 1. The tool detection instrument 3 is installed on the moving seat 2 and moves with the moving seat 2. The movable door 4 is connected with the moving seat 2 through elastic members 41; a first containing space extending along the length direction of the guide rail 1 is formed in the movable door 4, and the first containing space is used for containing the moving seat 2. The elastic members 41 have elastic potential energy for driving the movable door 4 to move towards the direction close to the moving seat 2. The fixed door 5 is installed on a machine tool gantry 8 and is located above the guide rail 1. A second containing space extending along the length direction of the guide rail 1 is formed in the fixed door 5; the second containing space is used for containing the movable door 4.

[0043] The two-stage electric push rod 6 comprises a first push rod 61 and a second push rod 62, the first push rod 61 is sleeved outside the second push rod 62; the end of the first push rod 61 is connected with the moving seat 2 and is used for driving the moving seat 2 to move along the length direction of the guide rail 1; the second push rod 62 penetrates through the moving seat 2 and is used for pushing the movable door 4 to move away from the moving seat 2. It is to be noted that the two-stage electric push rod 6 is prior art, which is not described in detail in the embodiment. In addition, the two-stage electric push rod 6 is at least divided into synchronous telescopic type and asynchronous telescopic type according to its telescopic mode, and the asynchronous telescopic type two-stage electric push rod 6 is selected in the embodiment. When the asynchronous telescopic type two-stage electric push rod 6 is elongated, the first push rod 61 is elongated first and then the second push rod 62 is elongated; the contraction process is opposite. Therefore, in the embodiment, the moving seat 2 is first moved out of the fixed door 5 by the first push rod 61, and then the movable door 4 is pushed to move by the second push rod 62.

[0044] It is to be noted that in the embodiment, the tool detection instrument 3 comprises a tool detection instrument body 31, a tool detection instrument base 32, a tool detection instrument connecting rod 33, a tool detection instrument connecting rod 34 and a tool detection instrument connecting rod 35. Figure 4As shown, the length of the movable door 4 does not need to be greater than the length of the moving seat 2, that is, the moving seat 2 can be partially accommodated in the movable door 4, and correspondingly, the moving seat 2 can be partially accommodated in the fixed door 5, and only needs to ensure that the movable door 4 can partially overlap with the fixed door 5 to form comprehensive protection for the tool setting gauge 3. By using the above structure design, the size of the tool setting detection mechanism in the unfolded state can also be as small as possible, the space occupation in the unfolded state is reduced, and the stroke requirement of the secondary electric push rod 6 can also be reduced.

[0045] The tool setting detection mechanism of the gantry machine tool provided in the embodiment can comprehensively protect the tool setting gauge 3 by cooperation of the fixed door 5 and the movable door 4, so as to avoid damage of the tool setting gauge 3 by machining debris; and the moving seat 2 and the movable door 4 can be unfolded or folded by the secondary electric push rod 6, so that the overall volume of the tool setting detection mechanism in the folded state is reduced, and the interference of the tool setting stroke is reduced.

[0046] Specifically, referring to Figure 5 As shown, the moving seat 2 is provided with a through hole 21 extending along the length direction of the guide rail 1, and the through hole 21 accommodates the second push rod 62. The end of the through hole 21 is provided with a mounting groove 22; the end of the first push rod 61 is connected with a mounting seat 63; and the mounting seat 63 is mounted in the mounting groove 22. When the secondary electric push rod 6 is elongated, the moving seat 2 is pushed by the first push rod 61 to the position of the tool setting gauge 3, and the movable door 4 is moved by the second push rod 62 to completely expose the tool setting gauge 3. When the secondary electric push rod 6 is shortened, the movable door 4 is retracted by the elastic member 41 after the second push rod 62 is retracted, the moving seat 2 is moved by the first push rod 61, and the movable door 4 overlaps with the moving seat 2, and the movable door 4 overlaps with the fixed door 5.

[0047] As shown in Figure 3 and Figure 6 As shown, the movable door 4 is provided with a contact 42; the moving seat 2 is provided with a detection switch for detecting the contact 42. The detection switch includes a first detection switch 23 and a second detection switch 24; the first detection switch 23 and the second detection switch 24 are arranged along the length direction of the guide rail 1. The first detection switch 23 is close to the machine tool gantry 8, and the second detection switch 24 is away from the machine tool gantry 8; when the first detection switch 23 detects the contact 42, it indicates that the tool setting detection mechanism is in a state of not exposing the tool setting gauge 3, and the tool setting detection cannot be performed; when the second detection switch 24 detects the contact 42, it indicates that the tool setting detection mechanism is in a state of exposing the tool setting gauge 3, and the tool setting detection can be performed. Thus, the state of the tool setting detection mechanism can be easily distinguished.

[0048] Specifically, the movable door 4 is provided with a first opening 43 facing the fixed door 5, and the fixed door 5 is provided with a second opening 51 facing the movable door 4, so that the movable door 4 enters the second containing space of the fixed door 5 along the second opening 51. During the folding process of the tool detection mechanism, the moving seat 2 enters the first containing space through the first opening 43, and the movable door 4 enters the second containing space through the second opening 51.

[0049] Specifically, the moving seat 2 is further provided with a tool tip blowing seat 9. By blowing air flow through the tool tip blowing seat 9, impurities on the surface of the tool can be cleaned.

[0050] Specifically, the tool detection instrument 3 is a laser tool detection instrument 3, and other forms of tool detection instruments 3 can also be selected in other embodiments.

[0051] Specifically, the guide rail 1 is provided with a limiting step 11, which is used to limit the movement of the moving seat 2 along the length direction of the rail. The moving seat 2 is positioned by the limiting step 11, so as to ensure the position accuracy of the tool detection instrument 3 and the accuracy of the centering tool detection.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0053] The above-mentioned embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
