Then, the mounting plate 41 is placed close to the swing head 3, and at the same time, the positioning pin 46 is made to slide along the slide groove 45 in the direction away from the mounting plate 41. When the positioning plate is close to the swing head 3, it can be directly fixed and installed with bolts without having to adjust the position.

[0027] Specifically, a limiting groove 47 is provided on the surface of the slide groove 45 . The surface of the limiting groove 47 is slidably connected to a limiting block 48 . The limiting block 48 is fixedly connected to the surface of the positioning pin 46 .

[0028] The effect achieved by the above components is that the provided limiting groove 47 and limiting block 48 prevent the positioning pin 46 from being separated from the swing head 3 while not affecting the sliding of the positioning pin 46 .

[0029] Specifically, a spring 49 is fixedly connected to the surface of the limiting groove 47 , and the other end of the spring 49 is fixedly connected to the surface of the limiting block 48 .

[0030] The effects achieved by the above components are: the positioning pin 46 and the spring 49 can also play an auxiliary role in fixing and reducing shock for the installed tool 44 .

[0031] Specifically, the number of the mounting plate 41 , the L-shaped plate 42 , the positioning hole 43 , the sliding groove 45 , the positioning pin 46 , the limiting groove 47 , the limiting block 48 and the spring 49 are all four groups and are arranged in a circular symmetrical manner.

[0032] The effects achieved by the above components are as follows: the multiple sets of mounting plates 41 are provided so as to be able to mount multiple sets of cutting tools 44 on the swing head 3 for easy rotation and switching.

[0033] Specifically, a dust collection device 5 is provided on the surface of the mounting plate 41. The dust collection device 5 includes a dust collecting box 51. The dust collecting box 51 is fixedly mounted on the surface of the mounting plate 41. A telescopic rod 52 is fixedly connected to the surface of the dust collecting box 51. The other end of the telescopic rod 52 is fixedly connected to a dust collection hood 53.

[0034] The effect achieved by the above components is: the dust box 51 is set to collect dust and debris in a centralized manner for easy regular cleaning. The dust collection device 5 can be installed on any set of mounting plates 41. When the swing head 3 rotates to switch the tool 44, dust can be collected near the processing position.

[0035] Specifically, a dust suction pump 54 is fixedly installed on the surface of the dust collecting box 51 , a dust suction pipe 55 is fixedly connected to the surface of the dust suction pump 54 , and the dust suction pipe 55 is connected to the surface of the dust collection cover 53 .

[0037] Specifically, a plurality of fixing holes 56 are provided on the surface of the telescopic rod 52 , and a fixing bolt 57 is threadedly connected to the surface of any fixing hole 56 .

[0038] The effect achieved by the above components is: the length of the telescopic rod 52 can be adjusted using the fixing hole 56 and the fixing bolt 57, so that the position of the dust hood 53 can be adjusted according to the length of the tool 44 and the size of the workpiece, and it can be as close to the processing area as possible to facilitate dust collection without affecting the processing.

[0039] Working principle: By setting the positioning device 4, various types of tools 44 are first fixedly installed on multiple groups of mounting plates 41. When a certain tool 44 needs to be installed on the swing head 3 for operation, the positioning hole 43 on the mounting plate 41 can be directly aligned with the positioning pin 46 on the swing head 3, and the positioning pin 46 can be inserted into the positioning hole 43. Then the mounting plate 41 is close to the swing head 3, and the positioning pin 46 slides along the slide groove 45 in the direction away from the mounting plate 41 and compresses the spring 49. When the positioning plate is close to the swing head 3, it can be directly fixed and installed with bolts without having to adjust the position. The set limit groove 47 and limit block 48 prevent the positioning pin 46 from separating from the swing head 3 without affecting the sliding of the positioning pin 46. The set positioning pin 46 and spring 49 can also play an auxiliary fixing and shock absorbing role for the installed tool 44. The multiple groups of mounting plates 41 are set to be able to install multiple groups of tools 44 on the swing head 3. By setting the positioning device 4, when installing the tool 44 Auxiliary positioning is provided to improve efficiency and avoid frequent alignment and adjustment. It can also install multiple sets of tools 44 for switching and using and perform auxiliary fixation and shock absorption, which effectively improves the convenience of the equipment. In addition, by setting up a dust suction device 5, the dust suction pump 54 is started to suck the dust and debris generated by processing from the dust suction hood 53 through the dust suction pipe 55 into the dust collection box 51. The dust suction device 5 can be installed on any set of mounting plates 41. When the swing head 3 rotates to switch the tool 44, the dust near the processing position can be sucked at the same time. The length of the telescopic rod 52 can be adjusted by using the fixing hole 56 and the fixing bolt 57, so that the position of the dust suction hood 53 can be adjusted according to the length of the tool 44 and the size of the workpiece. It is as close to the processing area as possible without affecting the processing for easy dust suction. By setting up the dust suction device 5, dust suction can be performed at the same time during the process of switching the tool 44, avoiding the dust and debris generated by the processing from affecting the subsequent operations, which effectively improves the usability of the equipment.
