The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1 and 2, the automatic timber pushing device includes a base 10, a driving assembly and two limit switch assemblies, wherein a workpiece table 20 is arranged on the base 10, and the workpiece table 20 can reciprocate along a pushing direction under the driving of the driving assembly. In this embodiment, the pushing direction is the longitudinal direction of the base 10.

Specifically, the driving assembly comprises a mounting seat, a motor 31, a gear 32 and a rack 33, the rack 33 is mounted on the machine base 10, the gear 32 is meshed with the rack 33, the motor 31 is mounted on the mounting seat, and a rotating shaft of the motor 31 is synchronously connected with the gear 32; the mounting seat is arranged on the workpiece table 20; the two limit switch assemblies are respectively arranged at two ends of the machine base 10 in the pushing direction, namely, the two ends of the machine base 10 in the length direction are respectively provided with the limit switch assemblies.

The limit switch assembly comprises a limit switch plate 41 and a limit switch 42, the limit switch 42 is fixedly connected to the machine base 10, the limit switch 42 is installed on the limit switch plate 41, and the limit switch 42 can be used for detecting the pushing position of the workpiece table 20; the limit switch 42 is electrically connected to the motor 31.

It should be noted that the installation positions of the two limit switch assemblies on the machine base 10 may be the starting end and the tail end of the workpiece table 20, and in the initial state, the workpiece table 20 may be located at the starting end of the machine base 10.

On the basis of the structure, when the automatic timber pushing device of the utility model is used,

the wood can be placed on the workpiece table 20, after the wood is placed, the motor 31 can be started to drive the gear 32 to rotate, the gear 32 can rotate to move along the rack 33 meshed with the gear 32, the gear 32 is pivoted on the mounting seat, and the mounting seat is connected with the workpiece table 20, so that the gear 32 can move along the rack 33 to drive the workpiece table 20 to move along the rack 33, and the workpiece table 20 can be pushed in the length direction of the machine base 10. Specifically, when the workpiece table 20 moves to the position of the limit switch assembly at the end position of the machine base 10, the limit switch 42 may detect that the workpiece table 20 moves in place, and then send a signal to control the motor 31 to stop, and at this time, start the machining operation.

After the machining is finished, the motor 31 can rotate reversely, the gear 32 can move reversely along the rack 33, the resetting of the workpiece table 20 is realized, and in the resetting process, when the workpiece table 20 moves to the position of the limit switch assembly at the starting end position of the machine base 10, the limit switch 42 can detect that the workpiece table 20 moves in place, and then sends a signal to control the motor 31 to stop, and the transmission of the next workpiece is started.

It should be noted that, since the pushing manner of the workpiece stage 20 is realized by the meshing transmission of the gear 32 and the rack 33, the gear 32 and the rack 33 control the stroke by the meshing of the tooth grooves, the transmission precision is high, and the pushing speed is stable. In addition, the movement stroke of the gear 32 along the rack 33 is formed by matching the teeth of the gear 32 in the grooves of the rack 33, so that the movement stroke is easy to control, and the device is suitable for driving the workpiece table 20 with a small movement stroke.

Further, the driving assembly in this embodiment further includes a reduction box 34, and the rotatable shaft of the motor 31 is synchronously connected with the gear 32 through the reduction box 34, so that the rotating speed of the motor 31 is reduced by the transmission of the reduction box 34, and the gear 32 is driven to rotate stably, so that the pushing movement of the workpiece table 20 is more stable.

Furthermore, two limiting plates 11 may be disposed on the machine base 10, and the two limiting plates 11 are respectively disposed at two ends of the machine base 10 in the pushing direction. The bottom that corresponds at work piece platform 20 is equipped with stopper 21, and when work piece platform 20 moved along the propelling movement direction, stopper 21 can with limiting plate 11 butt.

Specifically, above-mentioned two limiting plates 11 can be located frame 10 initiating terminal and end on the propelling movement direction respectively, and when work piece platform 20 moved to initiating terminal or end, the stopper 21 that corresponds the position can carry out the butt cooperation with limiting plate 11, and the machinery that realizes work piece platform 20 through limiting plate 11 stops, and cooperation limit switch 42's use limiting displacement is better.

More specifically, a limiting groove 12 may be provided on the base 10, and the limiting groove 12 extends along the pushing direction. Two limiting plates 11 are respectively arranged at two ends of the limiting groove 12, and the limiting block 21 is arranged at the bottom end of the workpiece table 20 and moves in the limiting groove 12. Because the stopper 21 of work piece platform 20 bottom is protruding to be established, if do not set up the spacing groove 12 structure, need to have certain space to accomodate stopper 21 on the frame 10, therefore stopper 21 can only set up the lateral part at frame 10, and the both sides of frame 10 are provided with rack 33 and limit switch subassembly respectively, in order to prevent to produce the interference, therefore set up spacing groove 12 in the middle part of frame 10 in this embodiment and supply stopper 21 to slide, prevent to produce the interference in the slip process.

Furthermore, a slide rail 13 is arranged on the machine base 10, the top ends of the two side walls of the limiting groove 12 are provided with the slide rails 13, and the slide rails 13 extend along the pushing direction. The two sides of the bottom end of the workpiece table 20 are provided with sliding blocks 22, and the sliding blocks 22 are in sliding fit with the sliding rails 13.
