Technical Field

The invention is applied to the technical field of electric cylinders, and particularly relates to a novel guide rail device.

Background

The electric cylinder is a modularized product which integrates a servo motor and a lead screw, converts the rotary motion of the servo motor into linear motion, and simultaneously converts the best advantages of the servo motor, namely accurate rotating speed control, accurate revolution control and accurate torque control into accurate speed control, accurate position control and accurate thrust control; realizing a brand new revolutionary product of a high-precision linear motion series. Wherein the lead screw part still generally includes the base that is used for installing the lead screw and the inside slider that is equipped with screw-nut, usually sets up the linear guide with slider complex at the interior bottom surface of base in traditional lead screw part for it is spacing to the slider, however this kind of guide structure bears the position of torsion and concentrates, appears becoming flexible easily after using a period, can't work under the environment of big torsion for a long time.

Disclosure of Invention

The invention aims to solve the technical problem of overcoming the defects of the prior art and provides a novel guide rail device which is large in bearing torque and long in service life.

The technical scheme adopted by the invention is as follows: the guide rail device comprises a base, a motor, a screw rod and a slide block, wherein first guide strips are arranged on two sides of the inner wall of the base, second guide strips matched with the first guide strips are correspondingly arranged on two sides of the slide block, ball grooves are formed in the first guide strips and the second guide strips, balls are arranged between the first guide strips and the second guide strips, the screw rod is rotationally matched in the base, the motor is fixed at one end of the base, an output shaft of the motor is in transmission connection with one end of the screw rod, and the slide block is in transmission connection with the screw rod through a screw rod nut.

According to the scheme, the first guide strips are arranged on the two sides of the base, so that the structures bearing the torsion are distributed on the two sides of the sliding block, the torsion is effectively dispersed, the service life of the guide structure is prolonged, and the maximum bearing torsion is improved. Simultaneously through adopting the ball as guide structure, and then remove the wearing and tearing that sliding friction brought from, effectively prolong novel guide rail device's life.

One preferred scheme is, novel guide rail device still includes the push rod, the slider with push rod fixed connection, the push rod is hollow structure, the internal diameter of push rod is less than the biggest external diameter of lead screw, the lead screw is kept away from the one end cooperation of motor has the bearing, the bearing with the inner wall sliding fit of push rod, be provided with on the base with the slide bearing of push rod looks adaptation.

According to the scheme, the push rod is used for pushing and pressing articles, so that the novel guide rail device can perform press fitting, pressing and other work, the first guide strip arranged on the side face is used as a guide structure, and therefore the stable operation of the sliding block can be still ensured when the motor outputs large torque force to push and press the articles.

One preferred scheme is that one end of the push rod, which is far away from the screw rod, is provided with a threaded connector.

According to the scheme, the threaded connector is used for connecting an external pressing block or other connecting components.

Preferably, the first guide bar is embedded in the base.

According to the scheme, the first guide strip works more stably by adopting an embedded structure. Meanwhile, the number of the bulges is reduced, so that the sliding block is more attached to the inner wall of the base, and the sliding block works more stably.

Preferably, the novel guide rail device further comprises an upper cover fixedly connected with the base, and the upper cover and the base are matched to encapsulate the screw rod.

Preferably, both ends of the ball groove of the second guide strip are closed.

According to the scheme, the ball is prevented from derailing by adopting a design with two closed ends.

Detailed Description

As shown in fig. 1 to 4, in this embodiment, the present invention includes a base 1, a motor 2, a screw rod 3, and a slider 4, wherein both sides of an inner wall of the base 1 are provided with first guide bars 5, both sides of the slider 4 are correspondingly provided with second guide bars 6 matched with the first guide bars 5, both the first guide bars 5 and the second guide bars 6 are provided with ball grooves 7, balls 8 are arranged between the first guide bars 5 and the second guide bars 6, the screw rod 3 is rotatably matched in the base 1, the motor 2 is fixed at one end of the base 1, an output shaft of the motor 2 is in transmission connection with one end of the screw rod 3, and the slider 4 is in transmission connection with the screw rod 3 through a screw rod nut 9.

In this embodiment, the novel guide rail device further includes a push rod 10, the slider 4 is fixedly connected with the push rod 10, the push rod 10 is a hollow structure, the inner diameter of the push rod 10 is smaller than the maximum outer diameter of the lead screw 3, the lead screw 3 is far away from one end of the motor 2 is matched with a rotating bearing 11, the rotating bearing 11 is in sliding fit with the inner wall of the push rod 10, and a sliding bearing 12 matched with the push rod 10 is arranged on the base 1.

In this embodiment, a threaded connector 13 is disposed at one end of the push rod 10 away from the screw rod 3.

In the present embodiment, the first guide bar 5 is embedded in the base 1.

In this embodiment, the novel guide rail device further includes an upper cover 14 fixedly connected to the base 1, and the upper cover 14 and the base 1 cooperate to enclose the lead screw 3.

In this embodiment, both ends of the ball groove 7 of the second guide strip 6 are closed.

The working principle of the invention is as follows:

when the motor 2 drives the screw rod 3 to rotate, the screw rod nut 9 drives the sliding block 4 to do reciprocating linear motion under the driving of the screw rod 3, and the first guide strip 5 limits the second guide strip 6 through the ball 8, so that the sliding block 4 does linear motion.

When the sliding block 4 moves, the push rod 10 is driven to stretch, and then the pressing action is realized.
