[0051] The linear drive mechanism 3 of the vertical column is arranged vertically; the linear drive mechanism 3 of the transverse movement assembly is arranged horizontally.

[0052] The vertical column is installed on the transverse movement assembly to provide movement adjustment for the horizontal transverse position of the vertical column; the vertical column is used to drive the turret mounting seat 5 and the turret body 6 to move vertically together. In summary, the vertical and horizontal adjustment of the turret body 6 is realized.

[0053] The linear drive mechanism 3 further includes a motor 303 and a lead screw 304; the moving seat 302 is slidably connected to the inside of the strip-shaped shell 301 along the length direction of the strip-shaped shell 301, and one end of the moving seat 302 extends out from the opening of the strip-shaped shell 301. The lead screw 304 is rotatably installed in the strip-shaped shell 301, and the lead screw 304 is threadedly connected to a nut arranged on the moving seat 302. The motor 303 is fixedly installed on the outer wall of one end of the strip-shaped shell 301, and the output shaft end of the motor 303 is fixedly connected to one end of the lead screw 304.

[0054] Among them, the linear drive mechanism 3 of the transverse movement assembly is fixed to the outer wall of the strip-shaped shell 301 of the linear drive mechanism 3 of the vertical column through the moving seat 302, and the strip-shaped shell 301 of the linear drive mechanism 3 of the transverse movement assembly is fixedly connected to the lathe base 1.

[0055] Among them, the linear drive mechanism 3 operates as follows. The motor 303 drives the lead screw to rotate. The lead screw is screwed with the nut on the moving seat 302, and with the guiding function provided by the strip-shaped housing 301 for the moving seat 302, the moving seat 302 moves along the length direction of the strip-shaped housing 301.

[0056] The motor 303 is preferably a servo motor 303.

[0057] As Figures 2-4 As shown, the number of the protective shielding mechanisms 7 is four, and the four protective shielding mechanisms 7 are respectively installed at both ends of the two linear drive mechanisms 3; the protective shielding mechanism 7 includes a fixed cover 701, a soft belt 702, a rotating roller 703 and a clockwork spring 704; the fixed cover 701 is fixedly connected to the outer end wall of the strip-shaped housing 301, and a rotating roller 703 is rotatably installed inside the fixed cover 701. The soft belt 702 is wound around the rotating roller 703. The soft belt 702 passes through a through groove 3011 opened at the end of the strip-shaped housing 301, and a connecting strip 8 is fixedly connected to the end of the soft belt 702. The connecting strip 8 is connected to the detachable mechanism 9; a clockwork spring 704 is arranged on the rotating roller 703; the clockwork spring 704 is sleeved on the end of the rotating roller 703. One end of the clockwork spring 704 is fixedly connected to the cylindrical surface of the rotating roller 703, and the other end of the clockwork spring 704 is fixedly connected to the inner end surface of the fixed cover 701.

[0058] When the moving seat 302 slides along the length direction inside the strip-shaped housing 301, it will move away from one end of the strip-shaped housing 301. The moving seat 302 will drag and pull the soft belt 702 of the protective shielding mechanism 7 at this end, so that the soft belt 702 is pulled out, automatically adapting to shield the gradually increasing distance between the moving seat 302 and this end. When the soft belt 702 is pulled out, the rotating roller 703 rotates automatically, increasing the torsional force of the clockwork spring 704.

[0059] In the above, the moving seat 302 will approach the other end of the strip-shaped housing 301, and the distance between this end and the moving seat 302 gradually decreases. Among them, through the torsional elastic force of the clockwork spring 704, a force for winding the soft belt 702 is provided for the rotating roller 703, so that the excess soft belt 702 is automatically wound onto the rotating roller 703 to achieve automatic adaptive shielding.

[0060] It should be noted that when the moving seat 302 is at any position of the strip-shaped housing 301, the clockwork spring 704 is in a deformed state, always providing a force for winding the soft belt 702 for the rotating roller 703.

[0061] The soft belt 702 is preferably made of rubber or silica gel.

[0062] As Figures 5-6As shown, the detachable mechanism 9 includes a second cylinder 903 rotatably connected to the connecting bar 8; a stopper 904 is fixedly connected to the cylindrical surface of one end of the second cylinder 903 away from the connecting bar 8; one end of the second cylinder 903 is fixedly connected to a first cylinder 902, and the first cylinder 902 is fixedly connected to a screwing head 901. The screwing head 901, the first cylinder 902, and the second cylinder 903 are coaxially arranged. The screwing head 901 is attached to the surface of the connecting bar 8 facing away from the moving seat 302, and the end face of the second cylinder 903 is attached to the surface of the connecting bar 8 facing the moving seat 302. The first cylinder 902 is in fit connection with a circular through hole opened on the connecting bar 8; the diameter of the first cylinder 902 is smaller than the diameters of the screwing head 901 and the second cylinder 903; a circular insertion hole 10 for the second cylinder 903 to be inserted into is opened on the moving seat 302. An arc groove 12, a vertical groove 11, and an end groove 13 for the stopper 904 to slide are opened on the cylindrical surface of the circular insertion hole 10. The vertical groove 11 and the end groove 13 are both vertically arranged, and the bottom ends of the vertical groove 11 and the end groove 13 are respectively communicated with both ends of the arc groove 12. One end of the vertical groove 11 away from the arc groove 12 is open. A spiral spring 4 is arranged inside the circular insertion hole 10, and one end of the spiral spring 4 is fixedly connected to the circular insertion hole 10.

[0063] As Figure 5 shown, at this time, the detachable mechanism 9 installs the connecting bar 8 on the moving seat 302. At this time, there is a distance between the connecting bar 8 and the moving seat 302, the spiral spring 4 is in a compressed state, and the stopper 904 is located at one end of the end groove 13 away from the arc groove 12; when performing the disassembly operation, by pressing down the connecting bar 8 until the connecting bar 8 is attached to the moving seat 302. During this process, the connecting bar 8 drives the screwing head 901, the first cylinder 902, the second cylinder 903, and the stopper 904 to move together, so that the stopper 904 moves along the length direction of the end groove 13 and enters the junction of the arc groove 12 and the end groove 13. Then, rotate the screwing head 901 counterclockwise, so that the screwing head 901, the first cylinder 902, the second cylinder 903, and the stopper 904 rotate counterclockwise together. The stopper 904 moves along the length direction of the arc groove 12 and moves from the junction of the arc groove 12 and the end groove 13 to the junction of the arc groove 12 and the vertical groove 11. By repeating the above operations, the stoppers 904 of all the detachable mechanisms 9 on the connecting bar 8 move to the junction of the vertical groove 11 and the arc groove 12. Pull the connecting bar 8 to separate the connecting bar 8 from the moving seat 302, pull out the second cylinder 903 from the circular insertion hole 10, and pull out the stopper 904 from the open end of the vertical groove 11 away from the arc groove 12 to complete the disassembly.

[0064] When reconnecting, by bringing the connecting bar 8 close to the moving seat 302, all the second cylinders 903 on the connecting bar 8 are inserted into the circular jacks 10, and the stoppers 904 enter from the open end of the vertical groove 11 and move along the length direction of the vertical groove 11 to the junction of the arc groove 12 and the vertical groove 11. At the same time, the connecting bar 8 is in contact with the moving seat 302, and the compression coil spring 4 is compressed. Manually hold the connecting bar 8 in a state of being pressed against the moving seat 302, and then use the other hand to turn the screwing head 901 clockwise one by one, so that the stopper 904 moves along the arc groove 12 and enters the junction of the arc groove 12 and the end groove 13. Then release the connecting bar 8. Due to the elastic force of the coil spring 4 and the elastic force of the clockwork spring 704, the entire detachable mechanism 9 and the connecting bar 8 move away from the moving seat 302 and return to the state as shown in Figure 5 the figure shows, and there is a spacing between the connecting bar 8 and the moving seat 302.

[0065] It should be noted that the connecting bar 8 is an L-shaped bar with sufficient width. After the connecting bar 8 is disconnected from the moving seat 302, the clockwork spring 704 drives the rotating roller 703 to wind up the flexible belt 702, and the connecting bar 8 cannot enter the fixed cover 701 through the through groove 3011. After disconnection, the connecting bar 8 abuts against the inner end face of the strip-shaped shell 301.

[0066] The present utility model is not limited to the above embodiments. No matter what changes are made in its shape or structure, they all fall within the protection scope of the present utility model. The protection scope of the present utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principle and essence of the present utility model, but these changes and modifications all fall within the protection scope of the present utility model.
