[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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] When implementing: Figure 1-5 As shown, a four-axis suction rotary tailstock comprises a disc base 1, a support frame 2 and a support plate 5: the upper end of the disc base 1 is provided with a support frame 2, the upper end of the disc base 1 is provided with a support plate 5, and the side of the support plate 5 is provided with an exhaust structure 20;

[0024] The air extraction structure 20 includes an air suction pipe 10 and a mounting kit 8. The mounting kit 8 is disposed inside the support frame 2, and the air suction pipe 10 is disposed inside the support plate 5.

[0025] When the device is in use and the workpiece needs to be adsorbed and fixed, the suction pipe 10 is connected to a high-pressure air pump. The air pump then draws air to allow the suction pipe 10 to suck air into the interior of the installation kit 8, so that the installation kit 8 can be connected to the air pipe 14 and the product sample 11 to draw air, and then the workpiece is placed on the surface of the product sample 11 to be adsorbed and fixed.

[0026] The air intake pipe 10 passes through the support plate 5, the installation kit 8 passes through the support frame 2, and the inner wall of the support frame 2 is provided with a connecting rod 7;

[0027] A bearing 9 is provided on the side of the connecting rod 7, a mounting kit 8 is connected to the outer ring of the bearing 9, and an air intake pipe 10 is connected to the inner ring of the bearing 9;

[0028] When the device is in use, after the workpiece is fixed, the workpiece is rotated by the four-axis turntable. At this time, the installation kit 8 rotates with the air pipe 14, and the installation kit 8 drives the outer ring of the bearing 9 to rotate. At this time, the suction pipe 10 is connected to the inner ring of the bearing 9, so when the installation kit 8 rotates, it will not drive the suction pipe 10 to rotate, so as to prevent the suction pipe 10 from rotating with the workpiece, causing the suction pipe 10 to break, resulting in the disappearance of suction, and the workpiece falls from the surface of the product sample 11.

[0029] The inner wall of the support frame 2 is provided with a support fixing frame 19, and the interior of the support fixing frame 19 is provided with a rotating shaft body 6, and the rotating shaft body 6 is rotatably connected to the support frame 2;

[0030] A rotating disc 3 is provided on the side of the support frame 2, and the rotating disc 3 is rotatably connected to the support frame 2, and a mounting groove 15 is provided on the surface of the rotating disc 3;

[0031] When the device is in use, the workpiece is driven to rotate by the four-axis turntable of the device, and the product sample 11 is driven to rotate by the workpiece, so that the product sample 11 drives the supporting base plate 4 to rotate, and the rotating disk 3 is driven to rotate by the supporting base plate 4, and the rotating shaft 6 is driven to rotate by the rotating disk 3, so as to realize the rotation processing of the workpiece.

[0032] A fixing member 13 is disposed inside the mounting groove 15, and the fixing member 13 is slidably connected to the mounting groove 15. A supporting base plate 4 is disposed on the side of the rotating disc 3, and a fixing screw 12 is disposed on the side of the supporting base plate 4, and the fixing screw 12 is threadedly connected to the fixing member 13.

[0033] When the device is in use and the supporting base plate 4 needs to be installed, first insert the fixing member 13 into the installation groove 15, fit the supporting base plate 4 with the rotating disk 3, and align the holes on the surface of the fixing member 13 with the holes on the side of the supporting base plate 4, then screw the fixing screws 12 into the fixing member 13 to fix the supporting base plate 4 and the product sample 11.

[0034] An air connection pipe 14 is disposed on the side of the supporting bottom plate 4, a product sample 11 is disposed on the side of the air connection pipe 14, and an air hole 18 is opened on the surface of the product sample 11;

[0035] A fixing plate 16 is provided at the upper end of the support frame 2, and an oil filling hole 17 is provided at the upper end of the fixing plate 16;

[0036] When the device is in use and needs to adsorb and fix the workpiece, a high-pressure air pump is connected to the suction pipe 10 to allow the air pump to evacuate the suction pipe 10, so that the suction pipe 10 evacuates the installation kit 8, and the installation kit 8 is connected to the connecting air pipe 14 to evacuate the air. At this time, the air holes 18 on the surface of the product sample 11 are evacuated through the connecting air pipe 14 to adsorb and fix the workpiece, so as to prevent scratches on the surface of the workpiece during clamping and fixing, resulting in poor product quality. Lubricating oil can be injected into the rotating shaft 6 inside the support frame 2 through the oil filling hole 17 to prevent the friction between the support frame 2 and the rotating shaft 6 from increasing, resulting in damage to the device.

[0037] When the utility model is in use, firstly, the device is installed on the workbench through the disc base 1 and aligned with the four-axis turntable, and then the suction pipe 10 is connected to the high-pressure air pump. At this time, the air pump draws air to make the suction pipe 10 draw air to the installation kit 8, and make the installation kit 8 draw air to the connecting air pipe 14, so that the connecting air pipe 14 draws air to the air holes 18 on the surface of the product sample 11, so that the air holes 18 generate suction to adsorb and fix the workpiece on the surface of the product sample 11, and connect the other end of the workpiece to the four-axis turntable to process the surface of the workpiece. When the workpiece needs to be rotated, the workpiece is driven to rotate by the four-axis turntable, so that the workpiece drives the product sample 11 to rotate, and the rotating disc 3 is driven to rotate by the product sample 11, so that the rotating disc 3 is rotated through the rotating shaft 6, so as to achieve the purpose of rotating processing of the workpiece.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
