The technical scheme of the utility model is that criss-cross bearing of swing arm back-and-forth movement adds rack device, including setting up motor and the fixing base in the frame, the fixing base is located the below of motor, and the output shaft of motor passes the fixing base, is equipped with glide machanism on the fixing base, and the output shaft of motor is connected with glide machanism through rack and pinion mechanism, is equipped with the swing arm on the glide machanism.

The sliding mechanism comprises fixed sliding rails and sliding seats, the fixed sliding rails are symmetrically arranged on the fixed seat, and the sliding seats are located between the fixed sliding rails which are symmetrically arranged and are matched with the fixed sliding rails.

And a transmission groove is formed in the sliding seat, a rack is arranged on the wall of the transmission groove, and a pinion is arranged on an output shaft of the th motor and meshed with the rack.

The inner wall of the fixed slide rail is provided with a slide groove, the side wall of the slide seat is fixedly provided with a slide block, the slide block is positioned in the slide groove and matched with the slide groove, and the slide block is provided with a ball which is contacted with the slide groove.

And an output shaft of the th motor is perpendicular to a sliding seat of the sliding mechanism to form cross transmission.

The utility model discloses the motor drives the seat of sliding and removes along fixed slide rail under rack and pinion mechanism's effect, realizes the translation of swing arm, and whole transmission is stable, can not appear undulantly, and only drives the swing arm motion through the seat of sliding, and the momentum is little, and the direction is stable nimble the utility model discloses the slider on the seat of sliding is roll connection with the spout of fixed slide rail, reduces frictional force, reduces rack and pinion mechanism's load, improves driven stability and life.

Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of , but not all embodiments.

As shown in fig. 1-2, in embodiment 1, crossed bearing rack-adding devices with swing arms moving back and forth include a motor 2 and a fixed seat 3 disposed on a frame 1, a motor is vertically disposed on the frame, the fixed seat is disposed on the frame as required, and is connected to rotate or fixedly connected to the fixed seat.a fixed seat 3 is disposed below a motor 2, an output shaft of the motor 2 passes through the fixed seat 3, i.e., a through hole is disposed in the middle of the fixed seat, an output shaft of the motor passes through the through hole and extends out of the fixed seat, a sliding mechanism 4 is disposed on a lower end face of the fixed seat 3, an output shaft of the motor 2 is connected to the sliding mechanism 4 through a rack-and-pinion mechanism, and a swing arm 5 is fixedly disposed on the sliding mechanism 4. the motor 2 drives the sliding mechanism to move on a plane of the fixed seat through the rack.

, the sliding mechanism 4 includes two fixed slide rails 401 and sliding seats 402, the fixed slide rails 401 are symmetrically arranged on the fixed base 3, the fixed slide rails 401 are fixed on the fixed base through bolts, the sliding seats 402 are located between the fixed slide rails 401 symmetrically arranged and are matched with the fixed slide rails 401, namely, under the action of a motor and a rack-and-pinion mechanism, the sliding seats are driven to move along the fixed slide rails, so that the swing arm is translated, the sliding seats are only moved by the sliding seats, the weight is light, and the stability is good.

As shown in fig. 3-4, in the crossed bearing and rack device with swing arms moving back and forth in embodiment 2, the output shaft of the motor 2 is perpendicular to the sliding seat 402 of the sliding mechanism 4 to form crossed transmission, that is, the rotation of the motor is converted into the translation of the sliding seat through the pinion and the rack, the transmission mode is stable, no fluctuation occurs, and the swing arms are driven to move only through the sliding seat, the momentum is small, and the guiding is stable and flexible.

The other structure is the same as embodiment 1.
