At the same time, the grinding device can also be used to grind the worn tool to make the blade of the cutter head smooth. At the same time, by monitoring and maintaining the tool after connecting the tool, the tool can be maintained without disassembling, which can increase the functionality of the locking device and improve its practicality to a certain extent.

[0016] 2.

[0017] 3. After the tool body is fixed, the present invention starts the mechanical clamp to drive the limit block to move, and then the limit block can be pushed upward under the action of the mechanical clamp, so that the slot on the limit block can be engaged with the protrusion on the surface of the tool body, and in the subsequent use process, the engagement of the slot and the protrusion on the limit block can effectively prevent the tool from falling off due to vibration.

The modular welding tool quick locking device according to claim 2, characterized in that: The slide groove (9) is internally slidably connected with a support block (13), the top of the support block (13) is connected to an outer wall of one side of the connecting block 2 (11), and the bottom of the support block (13) is welded to the top of the cemented carbide substrate (3).

9. A method for using a modular welding tool quick locking device, applicable to a modular welding tool quick locking device according to any one of claims 1 to 6, characterized in that: The method of using the quick locking device is as follows: S1. When installing the modular welding tool, first use the clamping device to insert the tool body (2) into the interior of the connector (1), then start the micro electric push rod (26) to drive the insert block (27) to insert into the interior of the connecting hole (30), and energize the electromagnet three (28) so that the electromagnet three (28) can be attracted to the iron block two; S2, then starting the mechanical gripper (22) to drive the limit block (23) to move, so that the slot (24) on the limit block (23) can engage with the protrusion (20) on the tool body (2); S3, after the tool body (2) is fixed in the connecting head (1), the use of the tool head (4) is monitored by the control system, and when the tool head (4) is detected to be worn, the connecting plate (6) is controlled to move downward by the telescopic device, and then the storage ring (7) is driven to move downward by the connecting block (5) until the storage ring (7) is flush with the tool head (4); S4. When the storage ring (7) is flush with the cutter head (4), the diameter reducing rod assembly drives the four groups of limit plates (10) and the stopper (12) to expand outwards in four different directions or gather inwards to form a circular structure, and then drives the tool diameter adjustment assembly to adjust the spacing between the four groups of carbide substrates (3) until the cutter head (4) can be located in the grinding device, and then the worn cutter head (4) can be ground by the grinding device.

10. The method for using a modular welding tool quick locking device according to claim 9, characterized in that: In S4, it also includes: when the diameter-changing rod assembly is used to drive the storage blocks (15) to expand outward, the electromagnet (18) is powered off, so that each storage block (15) will expand outward under the action of the connecting plate (17), thereby increasing the diameter of the tool.
