The economic society develops rapidly, and the demand of mechanical production type enterprises on linear cutting equipment is increasing. On the one hand, solutions are needed to reduce costs; on the one hand, it is also desirable to improve the overall performance of the wire cutting machine. The wire cutting machine on the market at present has the following defects:
1. the stepping motor used by the traditional linear cutting machine has slow response and low precision;
2. the common thread screw rod used by the traditional linear cutting machine has large friction resistance and short service life;
3. the common bearing used by the traditional linear cutting machine has low axial precision, and the screw rod pair is easy to move.
Disclosure of Invention
The invention aims to provide a linear cutting lifting shaft system which is high in precision, quick in response and long in service life.
In order to achieve the purpose, the invention provides the following technical scheme: a wire-cut lifting shaft, comprising: the device comprises a servo motor, a bearing seat, a screw rod pair and a lifting rod; the screw rod pair penetrates through the center of the bearing and is directly connected with the servo motor through a coupling; the screw rod pair is arranged in the lifting rod; the bearing is embedded in the center of the bearing seat; the bearing block is fixedly connected with the lifting rod.
Further, the bearing is preferably an angular contact ball bearing, and the lead screw pair is prevented from moving.
Further, the screw pair is preferably a ball screw pair, eliminating axial play.
Furthermore, a lifting rod sleeve is fixedly connected and installed below the lifting rod, and the lifting rod is fastened.
Furthermore, a travel switch is fixedly connected and installed on the lifting rod to control the lifting rod to lift.
Further, the fixed connection mode is screw connection.
Compared with the prior art, the invention has the following beneficial effects:
1. the servo motor replaces the original stepping motor, and the servo motor is directly connected with the screw rod pair, so that the gap is greatly reduced, and the response is fast.
2. The ball screw pair replaces a common thread screw pair, so that the service life is prolonged, and the friction resistance is small.
3. The centripetal reasoning ball bearing replaces a common bearing, improves the axial precision and prevents the lead screw pair from moving.

Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
As shown in fig. 1, a screw pair 5 passes through the center of a bearing 3 and is directly connected with a servo motor 1 through a coupling 2; the screw pair 5 is arranged in the lifting rod 7; the bearing 3 is embedded in the center of the bearing seat 4; the bearing block 4 is connected with the lifting rod 7 through a screw; a travel switch 6 is arranged on the lifting rod 7 through a screw; a lifting rod sleeve 8 is arranged below the lifting rod 7 through a screw, and the effect of fastening the lifting rod is achieved.
When the servo motor is used, the servo motor 1 is started to be electrified and rotated, the servo motor 1 drives the coupling 2 to rotate, and meanwhile, the screw rod pair 5 arranged in the center of the bearing 3 in the bearing block 4 is driven to rotate. The screw pair 5 is preferably a ball screw pair, compared with a threaded screw pair in the prior art, balls in the ball screw pair are in gapless fit with a screw, and errors are greatly reduced. The bearing 3 is preferably a radial thrust ball bearing, and compared with a common bearing used in the prior art, the radial thrust ball bearing has no clearance, improves the precision and prevents the play. Compared with a stepping motor used in the prior art, the stepping motor is connected with the screw rod pair 5 through a gear, errors are amplified to a certain extent, the servo motor 1 is directly connected with the screw rod pair 5, the servo motor 1 is in gapless connection with the screw rod pair 5, and the equipment precision is greatly improved. The lifting rod 7 in threaded connection with the screw rod pair 5 starts to operate, when the lifting rod 7 moves to one end in a single direction, the travel switch 6 in a normally open state is closed, the lifting rod 7 moves in the opposite direction, lifting is achieved, and the lifting rod sleeve 8 below the lifting rod 7 plays a role in further fastening and preventing movement.
The service life of the wire-electrode cutting lifting shaft system in the traditional technology reaches 2-3 years, the service life of the wire-electrode cutting lifting shaft system adopting the novel linear cutting lifting shaft system can reach 5-8 years, and the service life is prolonged by 90%.
The errors of the linear cutting lifting shaft system in the prior art are in the percentage level, the errors of the linear cutting lifting shaft system adopting the method are reduced to the thousand level, and the actual errors are greatly reduced.
It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
