[0025] Figure 2-Figure 3 The utility model discloses a tool magazine broken tool detection structure, which includes a driving member 10 , a linear module 20 , a bracket 30 , a sensor 40 , a drag chain 50 , a fixing frame 60 , a shield 70 and a mounting seat 80 .

[0026] In this embodiment:

[0027] The driving member 10 is in transmission connection with the linear module 20, and the driving member 10 drives the slider 22 of the linear module 20 to perform linear motion. In this embodiment, the driving member 10 is a servo motor.

[0028] The linear module 20 includes a slide rail 21 and a slider 22. The slide rail 21 is fixed on the machine tool. The length direction of the slide rail 21 is parallel to or on the same straight line as the length direction of the tool 100. The linear module 20 moves at a fast speed, and the position is accurately, quickly and safely detected, which effectively improves the working efficiency of the machine tool.

[0029] The bracket 30 includes a connecting bracket 31 and a supporting bracket 32. The connecting bracket 31 is arranged at the bottom of the slide rail 21 and is fixedly connected to the slider 22 of the linear module 20. The length direction of the connecting bracket 31 is perpendicular to the length direction of the slide rail 21. The supporting bracket 32 ​​is vertically installed below the connecting bracket 31 and is detachably fixedly connected to the connecting bracket 31, so as to lengthen the overall length of the bracket 30 and facilitate contact sensing between the sensor 40 and the tool 100.

[0030] The sensor 40 is mounted on the support frame 32 and is connected to the control system for communication. The slider 22 of the linear module 20 drives the sensor 40 to move back and forth in a direction parallel to the slide rail 21. In this embodiment, the sensor 40 is a contact sensor 40. When working, the parameters of the tool 100 are set by the control system to determine the current moving distance of the sensor 40. After moving to the position, the sensor 40 contacts the tip of the tool 100. The sensor 40 gives a signal and feeds it back to the system to confirm the broken tool detection result. The tool magazine broken tool detection structure can realize the broken tool detection of the tool 100 with a maximum tool length of 500mm.

[0031] One end of the drag chain 50 is connected to the sensor 40, and the other end is connected to the slider 22, which is used to accommodate the wires of the sensor 40 to prevent the wires from being worn during the operation of the linear module 20, thereby affecting the use of the sensor 40 and reducing the detection efficiency and accuracy. In this embodiment, the drag chain 50 is a tank chain, which has a better protection effect.

[0032] The fixing frame 60 is arranged above the slide rail 21 and is used to fix the slide rail 21 on the machine tool, which is convenient for installation and maintenance. In this embodiment, the cross-section of the fixing frame 60 is L-shaped.

[0033] The shield 70 is disposed on and below the slide rail 21 , and is used to protect the linear module 20 , preventing chips from piling up on the slide rail 21 during tool changing, thereby affecting the movement efficiency and accuracy of the slider 22 .

[0034] The mounting seat 80 is disposed on one side of the slide rail 21 for mounting the driving member 10. In this embodiment, the length direction of the mounting seat 80 is perpendicular to the length direction of the slide rail 21.

[0035] When the present application is in use, when the old tool 100 on the spindle is replaced on the tool magazine 90, the driving part 10 drives the linear module 20 to drive the sensor 40 to move quickly to the tool changing position, align with the tool tip position point of the old tool 100 currently to be detected, touch and give a signal to complete the broken tool detection. After completing the detection, the linear module 20 quickly returns to the origin position, and the control system determines whether the old tool 100 is broken according to the detection result. In this way, the detection point and the tool changing point are at the same position, and will not affect the operation and processing of the new tool 100 on the spindle, and will not cause damage to the new tool 100, thereby improving the detection efficiency and having higher safety. The tool magazine broken tool detection structure can form an independent component, which can be detachably installed on the machine tool, so that disassembly and maintenance are more convenient, and the overall working efficiency of the machine tool is improved.

[0036] The present application also relates to a machine tool, including a tool magazine 90, a tool 100 and the above-mentioned tool magazine broken tool detection structure. Several tools 100 are installed on the tool magazine 90. Specifically, a tool magazine disk is provided on the tool magazine 90, and several tools 100 are installed on the tool magazine disk. When the tool magazine disk rotates, it drives the tool 100 to rotate to realize the spindle tool change. After the tool change action, the spindle returns the old tool 100 to the tool magazine 90. The slider 22 of the linear module 20 drives the sensor 40 to move into position and contact with the tip of the old tool 100. The sensor 40 gives a signal and feeds back to the system to confirm the broken tool detection result. After completing the detection, the linear module 20 quickly returns to the origin position, and the new tool 100 on the spindle continues to operate and process.

[0037] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
