[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This Swiss-type lathe tool breakage detection device uses the moving module of the Swiss-type lathe to move the mounting head and contact head, inserting the contact head deep into the drilled hole of the workpiece and contacting the bottom of the drilled hole. This pushes the moving disk to slide on the inner wall of the receiving hole, compressing the return spring.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A broken tool detection device for a Swiss-type lathe includes a mounting head 1, a housing 8 mounted on the bottom of the mounting head 1, a receiving hole 9 on the inner wall of the housing 8, a fixed plate 10 mounted on the top of the receiving hole 9, a return spring 11 fixedly connected to the bottom of the fixed plate 10, a movable plate 12 fixedly connected to the other end of the return spring 11, the movable plate 12 being adapted to slide on the inner wall of the receiving hole 9, a pressure sensor 13 mounted on the bottom of the fixed plate 10, a transmission rod 15 mounted on the bottom of the movable plate 12, an abutment post 14 mounted inside the movable plate 12, a stud 16 threadedly connected to the inner wall of the transmission rod 15, and a contact 17 mounted on the bottom of the stud 16.

[0023] In the above structure, when the contact 17 penetrates into the drill hole of the workpiece and contacts the bottom of the drill hole, it pushes the moving disk 12 to slide on the inner wall of the receiving hole 9, which further exerts a squeezing force on the return spring 11. Consequently, the end of the abutment column 14 away from the moving disk 12 exerts a squeezing force on the pressure sensor 13, which is further used to identify that there is no broken tool in the drill hole and that the drill hole is in a normal state.

[0024] In a preferred embodiment, a ring 2 is mounted on the outer edge of the mounting head 1, a Swiss-type machine tool holder 5 is mounted on the top of the mounting head 1 and the ring 2, three nuts 3 are mounted on the bottom of the ring 2, a bolt 4 is passed through the inner wall of the ring 2, the bottom end of the bolt 4 is threaded to the inner wall of the nut 3, and the nut of the bolt 4 abuts against the top of the Swiss-type machine tool holder 5.

[0025] In the above structure, the nut 3 and bolt 4 are used to stably install the mounting head 1 on the bottom of the Swiss Army machine tool holder 5, and to stably connect the ring 2 with the Swiss Army machine tool holder 5, which further ensures the stability after installation.

[0026] In a preferred embodiment, the top of the Swiss Army machine tool holder 5 is provided with three through holes 6, and the positions of the three through holes 6 and the three nuts 3 correspond to each other, and the three bolts 4 are inserted into the inner wall of the three through holes 6.

[0027] In the above structure, the three through holes 6 allow the bolt 4 to pass through the Swiss-type machine tool holder 5 and be threaded to the inner wall of the nut 3, thus achieving the connection between the ring 2 and the Swiss-type machine tool holder 5.

[0028] In a preferred embodiment, a plurality of protrusions 18 are mounted on the outer edge of the contact 17. Both the protrusions 18 and the contact 17 are made of rubber, which improves the ease with which the user can rotate the contact 17. Furthermore, it ensures that the contact 17 can be easily rotated to drive the stud 16 to rotate and disengage from the inner wall of the transmission rod 15, thereby enabling the disassembly and replacement of the contact 17.

[0029] In a preferred embodiment, the bottom of the housing 8 is provided with a through hole communicating with the receiving hole 9, and the transmission rod 15 is adapted to slide and connect to the inner wall of the through hole;

[0030] In the above structure, the through hole allows the transmission rod 15 to slide on the inner wall of the through hole, thereby pushing the moving disk 12 to slide on the inner wall of the receiving hole 9. Furthermore, it can push the end of the abutment post 14 away from the moving disk 12 to contact the pressure sensor 13 to transmit pressure.

[0031] In a preferred embodiment, a voice announcer 7 is mounted on the bottom of the ring 2, and a controller is mounted on the bottom of the ring 2. The voice announcer 7, the controller, and the pressure sensor 13 are all electrically connected.

[0032] In the above structure, the voice broadcaster 7, the controller, and the pressure sensor 13 are all electrically connected, so that when the pressure sensor 13 senses pressure, it can transmit a signal to the controller, and then the controller can transmit a signal to the voice broadcaster 7 in a timely manner, so that the voice broadcaster 7 can emit a qualified alarm sound, and further identify the workpiece as a qualified product.

[0033] In a preferred embodiment, the Swiss Army machine tool holder 5 is detachably mounted to the Swiss Army machine's moving module;

[0034] In the above structure, the moving module can drive the Swiss-type lathe tool holder 5 to move synchronously with the contact 17 to perform a tool breakage detection operation on the workpiece during drilling.

[0035] Working principle: First, the Swiss-type headstock 5 is securely connected to the mounting head 1 using bolts 4. Then, the Swiss-type headstock 5 is connected to the moving module of the Swiss-type headstock. The moving module then moves the mounting head 1 and the contact 17 until the contact 17 is inserted deep into the drilled hole of the workpiece and contacts the bottom of the drilled hole. This pushes the moving disk 12 to slide on the inner wall of the receiving hole 9, further exerting a compressive force on the return spring 11. Consequently, the end of the abutment column 14 away from the moving disk 12 exerts a compressive force on the pressure sensor 13, which is further used to identify the drill bit. If there is no broken tool in the hole and the drilling is in a normal state, the pressure sensor 13 can transmit a signal to the controller when it senses pressure. The controller can then transmit a signal to the voice announcer 7 in a timely manner, causing the voice announcer 7 to emit a qualified alarm sound. This further confirms that the workpiece is a qualified product. However, if there is a broken tool inside the hole, the contact 17 cannot penetrate to the bottom of the hole, and therefore cannot push the abutment post 14 to contact the pressure sensor 13. Consequently, the pressure sensor 13 cannot sense the pressure, cannot transmit a signal to the controller, and therefore cannot emit a qualified alarm sound.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
