Description

Technical Field

[0001] The utility model relates to the technical field of numerical control processing, and relates to an axis displacement structure of a vertical lathe. Background Art

[0002] The tool post of a vertical lathe usually adopts a horizontal rail structure for tool displacement and positioning switching, and relies on the positioning of the processing platform to perform vertical milling and other processing.

[0003] The displacement of the lathe is usually controlled by the CNC system to control the action sequence, movement amount and feed speed of the feed motion parts of the lathe's X and Z coordinate axes, and then combined with the spindle speed and positive and negative rotation, various shapes of shaft and disk-type rotating parts can be processed. The axial transmission and steering movement of the existing shaft displacement are usually completed at the docking position of the shaft, so that the switching gap between positive and negative rotation is often accompanied by a large amount of radial reaction force, which makes the shaft connection end prone to greater wear during high-intensity movement, resulting in limited transmission efficiency of the existing shaft displacement structure.

DETAILED DESCRIPTION

[0020] See also Figure 1-3 , the embodiments of the utility model are further described;

[0021] A vertical lathe shaft displacement structure comprises a shaft cylinder frame 1, wherein a main shaft 3 and a displacement shaft 4 are respectively penetrated at both ends of the shaft cylinder frame 1, and a plug handle seat 10 is embedded at one end of the shaft cylinder frame 1 close to the displacement shaft 4, and the main shaft 3 and the displacement shaft 4 are axially butted and fixed in the plug handle seat 10;

[0022] An inner cylinder 2 is embedded in one end of the shaft cylinder frame 1 close to the main shaft 3. A strip-shaped displacement groove 8 is axially opened at the junction of the inner cylinder 2 and the main shaft 3, and a matching sliding handle protrudes from the main shaft 3 into the displacement groove 8.

[0023] A pressure contact plate 11 is separated between the connector handle seat 10 and the shaft tube frame 1, and a shaft tube 12 is adjacent to the pressure contact plate 11 in the inner end of the shaft tube frame 1. A compression shaft rod 13 extends from the pressure contact plate 11 into the shaft tube 12, and the compression shaft rod 13 is slidably connected to the shaft tube 12.

[0024] The two ends of the axial structure of the lathe shaft displacement structure use the main shaft 3 and the displacement shaft 4 as the butt joint structure of the shaft body transmission end. In the structure, the shaft bodies of the main shaft 3 and the displacement shaft 4 are both rotatably matched with the shaft tube frame 1, wherein the main shaft 3 and the displacement shaft 4 are linked by a fixed butt joint connector 10. At the butt joint end thereof, the axial butt joint of the pressure contact plate 11 and the shaft tube 12 structure is used to adjust the axial butt joint position of the pressure contact plate 11 and the shaft tube frame 1 through the sliding match of the compression shaft rod 13 and the shaft tube 12 when the shaft displacement structure generates a radial reaction force, so as to avoid the situation where the radial structural force of the rigid fixed structure in the shaft body movement affects the shaft body movement;

[0025] At the same time, at the movable ends of the main shaft 3 and the displacement shaft 4, the relative axial displacement of the main shaft 3 in the displacement groove 8 is utilized to adapt to the axial displacement changes of the pressure contact plate 11 and the displacement shaft 4 through the displacement groove 8 adapted to the inner cylinder 2. While ensuring the docking activity of the shaft structure, the influence of the radial force during the axial transmission switching process is further avoided. Compared with the existing shaft displacement structure, the activity stability and safety of the shaft displacement structure are improved.

[0026] On the basis of the above, a shaft handle 5 is fixed to one end of the main shaft 3 relative to the shaft cylinder frame 1, and a semi-convex tooth is protruded from the inner edge of the shaft handle 5. The end of the shaft handle 5 serves as the docking shaft part between the main shaft 3 and the lathe shaft body, wherein the protruding semi-convex tooth is fixedly docked with the shaft body to adapt to the rotation of the main shaft 3.

[0027] Preferably, a flange 15 is fixed to one end of the displacement shaft 4 relative to the shaft cylinder frame 1, and a screw tube kit 14 is sleeved on the middle part of the displacement shaft 4. The displacement shaft 4 uses the flange 15 as an elbow docking end, and the screw tube kit 14 serves as an external threaded connection structure to adapt to the steering adjustment structure of the lathe. The axial displacement adjustment is carried out by cooperating with the lathe through the rotational activity of the screw tube kit 14.

[0028] Preferably, a bearing seat 6 is axially matched between the inner cylinder 2 and the main shaft 3, and a ball ring tube 7 is movably arranged in the bearing seat 6, the main shaft 3 and the ball ring tube 7 are rotationally matched, and the main shaft 3 and the inner cylinder 2 structure are rotationally matched through the arranged bearing seat 6, so that the main shaft 3 can perform relative axial rotation along the inner cylinder 2 and the shaft cylinder frame 1, wherein the ball ring tube 7 maintains the position accuracy of the axial structure while ensuring the rotation of the main shaft 3 and the inner cylinder 2.

[0029] Preferably, a slewing ring 9 is rotatably engaged between the main shaft 3 and the inside of the shaft cylinder frame 1. The slewing ring 9 is relatively located between the inner cylinder 2 and the shaft tube 12. The slewing ring 9 is a metal crank structure, which is mounted relatively outside the inner cylinder 2 and the shaft tube 12 to isolate the inner cylinder and the shaft tube 12 structures while cooperating with the rotation structure of the main shaft 3, thereby ensuring the independence of the movements of the main shaft 3 and the displacement shaft 4.

[0030] Preferably, the intersection of the shaft tube 12 and the compression shaft rod 13 is interference fit, and the interference fit of the shaft tube 12 and the end of the compression shaft rod 13 is used to limit the maximum feed position of the compression shaft rod 13 to avoid slipping and displacement of the compression shaft rod 13, thereby ensuring the displacement accuracy of the shaft tube 12 and the pressure contact plate 11.

[0031] The implementation method of the device is to use the end of the main shaft 3 as the rotating end of the axial structure, and the end of the displacement shaft 4 as the axial horizontal displacement structure end. The main shaft 3 and the displacement shaft 4 are respectively docked and fixed with the lathe shaft drive shaft. The rotational activity of the main shaft 3 and the relative displacement activity of the displacement shaft 4 will be isolated by the inner cylinder 2 and the slewing ring 9. At the same time, during the axial movement, the axial docking activity of the pressure contact plate 11 and the connector handle seat 10 is used to axially compress the shaft tube 12 and the compression shaft rod 13. At the same time, the relative axial movement of the main shaft 3 and the displacement groove 8 is used to match the activity of the docking end of the connector handle seat 10, so as to avoid the influence of radial force accumulation on the activity during axial movement and positive and reverse steering switching.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
