[0025] As Figure 1 And Figure 2 , laser cutting head 11 is installed on cutting head mounting plate 12, cutting head mounting plate 12 is installed to mounting seat 13 by the adsorption force of magnetic block 131 and mounting column 132, when laser cutting head 11 collides with workpiece, the impact force is greater than the adsorption force of magnetic block 131 and mounting column 132, and then makes cutting head mounting plate 12 displace from mounting seat 13, reduces the damage to laser cutting head 11, since the diameter of mounting column 132 is greater than the diameter of magnetic block 131, if the impact force is small, makes mounting column 132 and magnetic block 131 still adsorbed, only mounting column 132 moves, makes cutting head mounting plate 12 and mounting seat 13 misplacement distribution, reduces the damage to laser cutting head 11, the setting of guide facilitates operator to install cutting head mounting plate 12 on mounting seat 13, cutting head mounting plate 12 and mounting seat 13 are still coaxial distribution, facilitate the adsorption of magnetic block 131 and mounting column 132.

[0026] As Figure 1 And Figure 2The cutting head mounting plate 12 is provided with mounting holes 133 for mounting columns 132, the mounting columns 132 are threadedly connected with the mounting holes 133, facilitating mounting of the mounting columns 132 on the cutting head mounting plate 12, and the mounting columns 132 are provided with hexagonal recesses (not shown in the figure) on the side away from the mounting base 13, facilitating the operator to rotate the mounting columns 132 out of the mounting holes 133.

[0027] As Figure 3 and Figure 4 The guide member includes a mounting groove 134 provided on the side of the mounting base 13 facing the cutting head mounting plate 12, a sleeve 135 is slidingly connected in the mounting groove 134, the end of the sleeve 135 away from the groove bottom is tapered, and the end with smaller taper is close to the cutting head mounting plate 12, the groove bottom of the mounting groove 134 is provided with a compression spring 136, the end of the compression spring 136 away from the groove bottom of the mounting groove 134 is fixed on one end of the sleeve 135, when the compression spring 136 is in the original state, the end with taper of the sleeve 135 extends out of the slot of the mounting groove 134, the cutting head mounting plate 12 is provided with a guide groove 137 for the end with taper of the sleeve 135 to enter, the groove wall of the guide groove 137 is provided with a guide block 138 sliding on the outer wall of the sleeve 135, the outer wall of the sleeve 135 is provided with a guide groove 14 for the guide block 138 to slide, the guide groove 14 is distributed along the length direction of the outer wall of the sleeve 135, the guide groove 14 facilitates the guide block 138 to slide in the guide groove 14, and when the guide block 138 slides into the guide groove 14, each mounting column 132 is distributed corresponding to the magnetic block 131, and the mounting base 13 is provided with a driving member for driving the sleeve 135 to move.

[0028] As Figure 3 and Figure 4 When the cutting head mounting plate 12 is hit, the operator needs to mount the cutting head mounting plate 12 on the mounting base 13 again, at this time, one end of the sleeve 135 extends out of the slot of the mounting groove 134, the operator makes the guide groove 137 on the cutting head mounting plate 12 to be sleeved on the outer wall of the sleeve 135, and then pushes the cutting head mounting plate 12 to the mounting base 13, at this time, the sleeve 135 is gradually moved into the mounting groove 134 under pressure, so that the cutting head mounting plate 12 gradually approaches the mounting base 13, in this process, the guide block 138 slides in the guide groove 14, until the cutting head mounting plate 12 is tightly abutted against the mounting base 13, at this time, the magnetic block 131 generates an attractive force on the mounting column 132, thereby fixing the cutting head mounting plate 12 on the mounting base 13; then the driving member drives one end of the sleeve 135 to move out of the guide groove 137, so that the cutting head mounting plate 12 and the mounting base 13 are not rigidly connected.

[0029] As Figure 2 and Figure 3 and Figure 4The driving member comprises an L-shaped driving slot 15 formed on the outer wall of the mounting base 13, the long side of the driving slot 15 is distributed along the length direction of the mounting base 13, and the short side is distributed away from the cutting head mounting plate 12, the driving slot 15 is communicated with the mounting slot 134, and the outer wall of the sleeve 135 is provided with a driving rod 151 extending out of the driving slot 15, when the driving rod 151 slides into the short side of the driving slot 15, one end of the sleeve 135 is separated from the guide slot 137.

[0030] As Figure 2 and Figure 3 and Figure 4 When it is needed to move one end of the sleeve 135 out of the mounting slot 134, the driving rod 151 is slid into the long side of the driving slot 15 from the short side, at this time, under the action of the compression spring 136, one end of the sleeve 135 moves out of the notch of the mounting slot 134, so that the cutting head mounting plate 12 is coaxially mounted with the mounting base 13, and then the magnetic block 131 is connected with the mounting column 132. When the cutting head mounting plate 12 is coaxially mounted with the mounting base 13, the driving rod 151 is pulled into the short side of the driving slot 15 by the operator, at this time, the sleeve 135 continuously moves towards the bottom of the mounting slot 134, and then one end of the sleeve 135 moves out of the guide slot 137 of the cutting head mounting plate 12 and completely enters the mounting slot 134.

[0031] The outer wall of the one end of the driving rod 151 extending out of the mounting base 13 is threadedly connected with a hexagonal nut (not shown in the figure), and the hexagonal nut is in abutment with the outer wall of the mounting base 13. After the driving rod 151 moves to the short side of the driving slot 15, the hexagonal nut is arranged to limit the position of the driving rod 151.

[0032] As Figure 2 Alternatively, the outer wall of the one end of the driving rod 151 extending out of the mounting base 13 is threadedly connected with a locking cylinder 152, a limiting slot is formed on the outer wall of the mounting base 13 for the one end of the locking cylinder 152 to enter, and the outer wall of the locking cylinder 152 is threadedly connected with the slot wall of the limiting slot. At this time, after the driving rod 151 moves to the short side of the driving slot 15, the locking cylinder 152 is rotated, so that the lower end of the locking cylinder 152 enters the limiting slot and is threadedly connected with the limiting slot, thereby further limiting the position of the locking cylinder 152 and further limiting the position of the driving rod 151 in the driving slot 15.

[0033] As Figure 2 and Figure 3When the cutting head mounting plate 12 is separated from the mounting base 13, in order to reduce the falling of the cutting head mounting plate 12, a spring rope 16 is arranged at the bottom of the mounting groove 134, and the end of the spring rope 16 away from the mounting groove 134 is fixed at the bottom of the guide groove 137. At this time, after the cutting head mounting plate 12 is separated from the mounting base 13, the spring rope 16 is in a tensioned state, and a pulling force is generated on the cutting head mounting plate 12. When the cutting head mounting plate 12 is connected with the mounting base 13, the spring rope 16 is in a relaxed state.

[0034] Obviously, various modifications and variations of the present application can be made by those skilled in the art without departing from the spirit and scope of the present application. Thus, it is intended that the present application include modifications and variations of this application within its scope.
