As fig. 1 to 4, the utility model relates to a safe tailstock of high accuracy for automizing lathe, including tailstock seat 1, main shaft 2, top 3, spring 4, pull rod 5, stop nut 6 and displacement sensor 7, main shaft 2 rotates to be connected in tailstock seat 1, and pull rod 5 wears to locate in main shaft 2, and outside main shaft 2 was stretched out respectively at the both ends of pull rod 5, top 3 and stop nut 6 fixed respectively at the both ends of pull rod 5. The spring 4 is sleeved on the pull rod 5, one end of the spring 4 is abutted on the inner wall of the main shaft 2, the other end of the spring 4 is abutted on the pull rod 5, the limiting nut 6 is abutted on the outer end face of the main shaft 2 under the elastic force action of the spring 4, and the displacement sensor 7 is fixed on the tailstock base 1 and is arranged on one side of the limiting nut 6.
The utility model provides a pull rod 5 includes connecting rod portion 51 and centering 52, and the both ends of connecting rod portion 51 are equipped with the external screw thread, and the one end and the 6 threaded connection of stop nut of connecting rod portion 51, the other end and centering 52 threaded connection, spring 4 cover are established on connecting rod portion 51, and spring 4's one end is contradicted on centering 52.
The centering portion 52 includes a conical portion 521 and a cylindrical portion 522 which are integrally formed, and the conical portion 521 is screwed to the link portion 51.
A hole for inserting the pull rod 5 is arranged in the axis direction of the main shaft 2, and one side of the hole is of a taper hole structure matched with the taper part 521. Through the mutual cooperation of the conical part and the conical hole, the automatic centering of the pull rod 5 in the main shaft 2 can be realized (namely, the pull rod 5 is coaxial with the main shaft 2.
The head and the tail of the main shaft 2 are rotatably supported in the tailstock base 1 through bearings 8. Wherein the bearing mounting means of 2 head ends of main shaft is current conventional bearing location mounting structure, so the utility model discloses do not give unnecessary details to this content.
The bearing mounting structure at the tail end of the main shaft 2 is as follows: the tail end of the main shaft 2 is provided with a compression nut 21, a pressure spring 22 and a positioning plate 23, the compression nut 21 is in threaded connection with the main shaft 2, the pressure spring 22 and the positioning plate 23 are both sleeved on the main shaft 2, one end of the pressure spring 22 abuts against the compression nut 21, the other end of the pressure spring abuts against the positioning plate 23 on an inner ring of the tail end bearing, and an outer ring of the tail end bearing abuts against an inner wall surface of the tailstock base 1.
The tail part of the main shaft 2 is provided with a pressure spring 22, the main shaft can bear the axial force of a larger load, the high-precision requirement of long-term use can be ensured, and the precision change caused by expansion with heat and contraction with cold of the main shaft due to external heat conduction can be prevented.
The centre is arranged on the main shaft, the spring is arranged on the centre, the centre is movable back and forth, and the conical surface is centered. The movable center drives the pull rod to axially displace, and the distance of the axial displacement of the pull rod 5 in the main shaft 2 is 1-2 mm. The conical surface of the center is centered, the precision is high, hard alloy is embedded at the conical tip of the center 3, and the strength is high.
