[0038] Embodiment 1:

[0039] See also Figure 1 - Figure 7 As shown, this embodiment provides a connection sleeve assembly for a suction nozzle, comprising:

[0040] The connecting sleeve body 1 is composed of a base 10, a positioning area 11, a knob area 12 and a limiting area 13, and the base 10, the positioning area 11, the knob area 12 and the limiting area 13 are an integrally formed structure.

A vent hole 25 adapted to the inner diameter of the leak-proof tube 24 is provided on the positioning area 11 and at a coaxial position with the leak-proof tube 24. A through groove 26 connected to the inner cavity of the limiting area 13 is provided in the knob area 12. Threaded holes 20 are symmetrically provided on the circumferential outer wall of the base 10 and close to the movable groove 19. The threaded holes 20 are threadedly connected with fastening bolts 21;

[0041] A suction nozzle assembly, which is located directly above the connecting sleeve body 1 and is plugged into and matched with the connecting sleeve body 1, and is used to absorb and take the machine tool workpiece;

[0042] A limiting component, which is located on the limiting area 13 and is used to constrain and limit the nozzle assembly and the connecting sleeve body 1;

[0043] In this embodiment, the nozzle assembly includes:

[0044] A connector 2, the bottom of which is a cone-shaped structure, the upper part of which is cylindrical, and the upper part of which is matched with the inner diameter of the inner cavity wall of the limiting area 13, a positioning groove 3 is provided between the upper and lower parts of the connector 2, a cylindrical through hole is provided in the connector 2, and a limiting groove 4 communicating with the outside is provided on the inner wall of the through hole of the connector 2, a straw 5 with a T-shaped interface is installed in the through hole of the connector 2, a pipe sleeve 6 is sleeved on the circumferential outer wall of the straw 5, and the pipe sleeve 6 is fixed to the straw 5, a limiting protrusion 7 slidably connected to the limiting groove 4 is fixed on the circumferential outer wall of the pipe sleeve 6, a conical nozzle head 8 is inserted and fixed on the upper surface of the straw 5, and a return spring 9 is fixed between the lower surface of the annular protrusion on the upper part of the straw 5 and the upper surface of the connector 2;

[0045] In this embodiment, the limiting component includes:

[0046] An annular groove 14 is provided on the circumferential outer wall of the limiting area 13. A plurality of circular holes 15 equidistantly distributed around the circumference are provided on the annular groove 14. Steel balls 16 are placed in the circular holes 15. Anti-skid grooves 17 are symmetrically provided on the upper surface of the limiting area 13. A limiting ring 18 is sleeved on the limiting area 13 and located at the position of the annular groove 14. A protrusion matching the anti-skid groove 17 is provided on the limiting ring 18. The protrusion on the limiting ring 18 is plugged into the anti-skid groove 17.

[0047] Among them, the working principle of this device is as follows:

[0048] During installation, when fixing the nozzle assembly, directly insert the lower part of the connector 2 in the nozzle assembly into the circular cavity of the limiting area 13. During this process, the circumferential outer wall of the connector 2 squeezes the steel balls 16, and multiple steel balls 16 move outward and squeeze the limiting ring 18. When the positioning grooves 3 on the connector 2 are completely inserted into the positions of multiple steel balls 16, under the elastic effect of the limiting ring 18, the steel balls 16 move toward the inner cavity of the limiting area 13 and are inserted into the positioning grooves 3, thereby achieving the fixation of the connector 2. When fixing the air pipe, insert one end of the air pipe into the insertion hole 22 from the bottom of the base 10, and press it inward with force, and then tighten the two fastening bolts 21. Under the action of the two fastening bolts 21, the two ends of the base 10 separated by the movable groove 19 approach the center side and squeeze the air pipe, thereby achieving fixation with the air pipe.

[0049] When using, refer to Figure 1-3 , the small hole on the upper end of the suction nozzle head 8 faces the material, and the connecting sleeve and the suction nozzle assembly are squeezed toward the material under the drive of the machine tool equipment. The suction nozzle head 8 is squeezed and moves downward and pushes the suction tube 5 to move downward. The suction tube 5 is squeezed and pushes the reset spring 9, causing the reset spring 9 to produce compression deformation. At this time, the limiting protrusion 7 slides in the limiting groove 4 until the lower surface of the limiting protrusion 7 fits with the lower edge of the inner cavity of the limiting groove 4. At this time, the air pipe works and generates negative pressure by suction. The air in the inner cavity of the suction tube 5 enters the inner cavity of the leak-proof tube 24 along the air vent 25 and passes through the air The suction pipe 5 is drawn out to the outside world by the action of the air pipe. At this time, there is a large negative pressure at the position where the top of the suction nozzle head 8 fits the material, so that the suction nozzle head 8 sucks up the material and completes the material replacement or loading and unloading operation. In this process, the return spring 9 plays a buffering role to prevent the top of the suction nozzle head 8 from damaging the material when it contacts the surface of the material. Furthermore, when it is not necessary to use the suction nozzle assembly to suck the material, it is only necessary to replenish air into the suction pipe 5 through the air pipe to make the negative pressure in the suction pipe 5 disappear. At this time, the suction nozzle head 8 loses its adsorption force on the material, thereby completing the unloading.

[0050] When disassembling, you only need to loosen the two fastening bolts 21 to pull the air pipe out from the bottom of the base 10. When replacing the suction nozzle assembly, you only need to pinch the main part of the connecting piece 2 with your hand and pull it toward the side away from the connecting sleeve body 1 to separate the suction nozzle assembly from the connecting sleeve body 1.

[0051] By setting a limit assembly, the elasticity of the limit ring 18 is used to wrap and reset the steel balls 16 located in the multiple circular holes 15, and the multiple steel balls 16 are snap-fitted with the positioning grooves 3 on the connecting piece 2 to constrain and limit the suction nozzle assembly and the connecting sleeve body 1, so that it is convenient for operators to install and disassemble the suction nozzle assembly. Compared with the traditional method of completely fixing the suction nozzle and the connecting sleeve into an integrated structure, the maintenance cost of the device is lower, and when the assembly fails, the suction nozzle assembly can be quickly disassembled and reinstalled, which greatly saves the maintenance time of the operator and improves the maintenance efficiency; by setting the connecting sleeve body 1, and opening a movable groove 19 at the position of the base 10 on the connecting sleeve body 1, the two parts of the base 10 divided by the movable groove 19 are fastened by two fastening bolts 21, so that the device can be directly connected to the air pipe without an external suction nozzle pipe, which greatly improves the convenience of the device when in use and reduces the overall use cost of the device.
