DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application solves the problem that the overall structure of the current tool magazine is usually simple, the tool is clamped in the slot inside the tool magazine, and the tool magazine is used to adjust the position of the tool magazine to align the tool changing spindle with different tools for replacement. However, when the robot arm drives the tool changing spindle to change the tool, the tool changing process is often prone to excessive force, resulting in a large impact force between the tool changing spindle and the tool magazine, thereby causing wear on the tool and the tool changing spindle, thereby reducing the stability of the tool and the service life of the equipment.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses an anti-collision mechanism for installing a tool change spindle.

[0026] The buffer table 2 is provided with an adjustment mechanism for driving the tool magazine rotating disk 3 to rotate and limit;

[0027] A first buffer mechanism is provided on the tool magazine base 1 for providing anti-collision protection for the buffer table 2;

[0028] The second sleeve 4 is provided with a second buffer mechanism for providing anti-collision protection to the tool clamping sleeve 5 .

[0029] Furthermore, the first buffer mechanism includes a vertical plate 101 fixedly connected to the tool magazine base 1, a first sleeve 102 fixedly connected to the vertical plate 101, a first sliding rod 103 slidably connected inside the first sleeve 102, the first sliding rod 103 is fixed to the buffer table 2, a first spring 104 is fixedly connected between the first sliding rod 103 and the inner cavity of the first sleeve 102, and the overall structure of the first buffer mechanism is compact. When an impact force is generated between the tool changing spindle, the buffer table 2 and the tool magazine rotating disk 3, the tool changing spindle will push the tool magazine rotating disk 3 and the buffer table 2 to move as a whole, and the buffer table 2 will drive the first sliding rod 103 to move along the inside of the first sleeve 102 and squeeze the first spring 104, thereby achieving buffering of the impact force and reducing the wear of the equipment caused by the impact force during the tool changing process.

[0030] Furthermore, the second buffer mechanism includes a second sliding rod 401 slidably connected to the inside of the second sleeve 4, the second sliding rod 401 is fixed to the tool clamping sleeve 5, and a second spring 402 is fixedly connected between the second sliding rod 401 and the inner cavity of the second sleeve 4. The second buffer mechanism has a simple structure, and the second spring 402 is used to provide buffering for the position of the second sliding rod 401 and the tool clamping sleeve 5. When an impact force is generated between the tool changing spindle and the tool and the tool clamping sleeve 5, the impact force will drive the tool clamping sleeve 5 and the second sliding rod 401 to move and squeeze the second spring 402 to achieve buffering.

[0031] Furthermore, the second sliding rod 401 passes through the second sleeve 4 and is fixedly connected with a baffle 403. The baffle 403 is provided to provide a limit for the second sliding rod 401 and the tool clamping sleeve 5. When the tool clamping sleeve 5 is not subjected to force, the second spring 402 pushes the tool clamping sleeve 5, the second sliding rod 401 and the baffle 403 to move as a whole, and makes the baffle 403 fit the second sleeve 4.

The overall structure of the adjustment structure is simple, and it is convenient to realize the rotational drive of the tool magazine rotating disk 3. The motor body 202 provides power, the motor body 202 drives the worm 203 to rotate, the worm 203 drives the worm wheel 301 to rotate, and the worm wheel 301 drives the tool magazine rotating disk 3 to rotate.

[0033] The tool changing spindle is installed with an anti-collision mechanism. During the tool changing process of the tool changing spindle, the tool magazine rotating disk 3 is adjusted to a rotation adjustment position through the adjustment mechanism to change the tool. After changing to the target tool, during the tool changing process, when the tool changing spindle contacts and squeezes the tool, the first buffer mechanism and the second buffer mechanism are used to provide anti-collision protection for the tool changing spindle, thereby reducing the wear of the tool and the tool changing spindle, thereby improving the stability of the tool changing spindle when changing tools and increasing the life of the equipment.
