Detailed Description
The present invention will be further described with reference to fig. 1 to 3, in which a single motor is first used to drive the motor to rotate, the motion is transmitted to the input shaft worm 1 through the belt pulley 2, the worm 1 drives the worm wheel 4 to rotate, the end surface of the worm wheel 4 is provided with a groove, and forms a cam mechanism with the first roller 6 sliding inside the cam mechanism, the first roller 6 moves in the groove on the end surface of the worm wheel 4, and drives the connecting rod 11 to transmit the motion to the connecting shaft of the mechanical arm 3, so as to complete the transverse feeding; meanwhile, the worm wheel 4 is in threaded connection with the continuous operation space cam 5, the continuous operation space cam 5 is in key connection with the processing shaft 10, the continuous operation space cam 5 is driven to rotate when the worm wheel 4 rotates, the second roller 8 moves in the groove of the continuous operation space cam to drive the output shaft 9 to rotate, and the gear on the output shaft 9 is meshed with the gear 7 on the connecting shaft of the mechanical arm 3, so that the rotation of the mechanical arm 3 is completed.
The utility model discloses a mechanical structure operation principle as follows:
s1, the motor operates to transmit motion to the input shaft worm 1 through belt drive.
And S2, transmitting the motion to the processing shaft 10 through the worm wheel 4 and the worm 1.
S3, the end face of the worm wheel 4 is provided with a groove, the groove and the first roller 6 sliding in the groove form a cam mechanism, and the movement is transmitted to the connecting shaft of the mechanical arm 3 through the connecting rod 11 connected to the first roller 6, so that the transverse feeding movement of the mechanical arm 3 is realized.
S4, and the worm wheel 4 on the processing shaft 10 and the special continuous operation space cam 5 are connected by screw thread in S2, so as to realize the simultaneous rotation of the two. The continuous running space cam 5 transmits the motion from the second roller 8 running in its groove to the output shaft 9.
S5, the gear 7 on the output shaft 9 is meshed with the gear on the connecting shaft of the mechanical arm 3, and the rotary motion is transmitted to the connecting shaft of the mechanical arm 3, so that when the cam 5 rotates in the continuous operation space, the mechanical arm 3 also rotates along with the rotation, and the rotary motion of the mechanical arm is realized.
