The work conveying apparatus of the present invention includes: the tool plate 100, the tool plate 100 is used for bearing the target workpiece; a first conveyance line 1 for conveying the tooling plate 100; the second conveying line 2 is used for conveying the tooling plate 100, and the extending direction of the second conveying line 2 and the extending direction of the first conveying line 1 form a preset included angle; the transfer structure 3 is positioned at the discharging end of the first conveying line 1, and the transfer structure 3 is positioned at the feeding end of the second conveying line 2; the transfer structure 3 is provided with a driving component for driving the tooling plate 100 to move; the transfer structure 3 is rotatably arranged to have a first state of abutment with the first conveyor line 1 and a second state of abutment with the second conveyor line 2. Like this, when transfer structure 3 is in the first state, can receive frock board 100 from first transfer chain 1, and when transfer structure 3 rotated to the second state, through frock board 100 transfer to the second transfer chain 2 on drive assembly drive is last, thereby realize the transfer of frock board 100 between first transfer chain 1 and second transfer chain 2, the work piece conveyor of this kind of structure has not only realized turning smoothly of transfer chain, and has reduced area effectively, the inconvenient problem of transfer chain turn among the prior art has been solved.

Specifically, the transfer structure 3 is provided with a stopper 34 to prevent the movement of the tooling plate 100 by the stopper 34 when the tooling plate 100 moves to a predetermined position on the transfer structure 3; the drive assembly includes: a drive shaft 31, the drive shaft 31 being rotatably provided; a rolling member 32, the rolling member 32 having a shaft hole, the driving shaft 31 passing through the shaft hole, the rolling member 32 being rollably disposed with respect to the driving shaft 31; the friction member 33, the friction member 33 are in contact with both the drive shaft 31 and the rolling member 32. Thus, when the tool plate 100 is conveyed, the friction member 33 can restrict the relative rotation between the rolling member 32 and the driving shaft 31, and smooth conveyance of the tool plate 100 can be ensured. When the tooling plate 100 moves to a predetermined position on the transfer structure 3, the blocking part 34 contacts with the tooling plate 100 to prevent the tooling plate 100 from moving, at this time, the static friction force between the rolling member 32 and the tooling plate 100 becomes large, and when the static friction force exceeds the maximum static friction force between the friction member 33 and the rolling member 32, the rolling member 32 and the driving shaft 31 rotate relatively, so that the rolling member 32 is kept in a static state, and the sliding friction between the rolling member 32 and the tooling plate 100 is avoided.

In this way, the rolling members 32 can be effectively fixed by the first friction plate 331 and the second friction plate 332, and by providing the elastic member 37, the reliability of the pressing of the first friction plate 331 and the second friction plate 332 against the rolling members 32 can be ensured, that is, the pressing and locking of the rolling members 32 can be ensured even in long-term repeated operation, thereby avoiding the situation of pressing failure caused by long-term friction between the first friction plate 331 and the rolling members 32 and the second friction plate 332, and ensuring smooth conveying of the tooling plate 100.
