[0046] refer to Figure 1 A spring plate 18 is fixedly connected to the right side of the detection device body 1. The spring plate 18 is located inside the shielding cover 3. The side of the spring plate 18 away from the detection device body 1 contacts the top of the inner wall of the shielding cover 3. The spring plate 18 is elastic, and the top of the spring plate 18 is slidably connected to the inner surface of the shielding cover 3.

[0047] As a technical optimization solution of the present invention, by providing a spring plate 18, the shielding cover 3 can be supported so that the shielding cover 3 has a reset effect, saving the user the operation steps of reciprocatingly moving the shielding cover 3.

[0048] refer to Figure 2 A shock absorbing ring 19 is fixedly connected to the left side of the shielding cover 3. The side of the shock absorbing ring 19 away from the shielding cover 3 contacts the right side of the detection device body 1. The shock absorbing ring 19 is made of damping silicone material, and the thickness of the shock absorbing ring 19 is greater than one centimeter.

[0049] As a technical optimization solution of the present invention, by providing a shock-absorbing ring 19, the impact force generated when the shielding cover 3 is reset can be weakened, and the shielding cover 3 and the detection device body 1 can be protected to avoid dry collision between the shielding cover 3 and the detection device body 1.

[0050] refer to Figure 1 The bottom of the detection device body 1 is fixedly connected to an airbag 20, the bottom of the airbag 20 is fixedly connected to a bottom plate 21, the front and back of the detection device body 1 are fixedly connected to a connecting plate 22, the top of the bottom plate 21 is fixedly connected to a guide rod 23, the top of the guide rod 23 passes through the connecting plate 22 and is slidably connected to the connecting plate 22, the airbag 20 is plastic, and the surface of the airbag 20 is composed of a plurality of protrusions and depressions arranged at intervals.

[0051] As a technical optimization solution of the present invention, by providing the airbag 20, the base plate 21, the connecting plate 22 and the guide rod 23, it is convenient for the user to effectively adjust the height of the detection device body 1 to meet the detection requirements of different types of tools and machining centers, thereby greatly improving the scope of application of the detection device body 1.

[0052] refer to Figure 1 The front and rear sides of the top of the bottom plate 21 are fixedly connected with an elastic frame 24, the elastic frame 24 is sleeved on the surface of the guide rod 23 and is slidably connected to the guide rod 23, the top of the elastic frame 24 is fixedly connected to the bottom of the connecting plate 22, and the elastic frame 24 is elastic.

[0053] As a technical optimization solution of the present invention, by providing an elastic frame 24 , the detection device body 1 can be supported to prevent the airbag 20 from shaking.

[0054] The working principle and use process of the present invention are as follows: when in use, the user connects the bottom plate 21 with the machining center, and then inflates the inside of the airbag 20, the airbag 20 expands and pushes the detection device body 1 to rise through the guidance of the guide rod 23, and according to the inflation amount of the airbag 20, the user can flexibly adjust the height of the detection device body 1, and then the user connects the transmission cable 2 with the connecting end of the detection device body 1. When the transmission cable 2 is installed, the user rotates the rotating wheel 8, the rotating wheel 8 drives the screw 9 to rotate, and the screw 9 uses the thread to push the extrusion rod 10 to move to the right, and the extrusion rod 10 releases to the shielding cover 3 through the extension plate 6 during the movement. The shielding cover 3 releases the pressure, and rotates with the pin shaft inside the connecting block 5 as the axis. When the shielding cover 3 is sleeved on the surface of the connecting end of the detection device body 1 and the transmission cable 2 is located inside the opening 4, the connecting end of the transmission cable 2 and the detection device body 1 is protected. The shielding cover 3 can use the support plate 16 to squeeze the transmission cable 2 during the rotation process, thereby improving the connection stability between the transmission cable 2 and the detection device body 1. During use, the tool inside the tool magazine of the machining center can contact the top of the detection device body 1 and judge the length of the tool under automatic tool alignment. The judgment result can be transmitted to an external computer through the transmission cable 2.

[0055] To sum up: the broken tool detector of the tool magazine of the machining center machine tool drives the screw 9 to rotate through the rotating wheel 8, and the screw 9 uses the thread to push the extrusion rod 10 to move to the right. During the movement, the extrusion rod 10 releases pressure to the shielding cover 3 through the extension plate 6, and the shielding cover 3 rotates around the pin shaft inside the connecting block 5. When the shielding cover 3 is sleeved on the surface of the connecting end of the detection device body 1 and the transmission cable 2 is located inside the opening 4, the connection end between the transmission cable 2 and the detection device body 1 is protected, which solves the problem that the structure of the existing broken tool detector is relatively simple and does not have the effect of shielding and protecting the structural part of the equipment. The connection exposed to the outside is easily affected by the coolant and short-circuited, which seriously affects the operating stability and detection accuracy of the broken tool detector and cannot meet the needs of various environments.
