The working process is described as follows:
Firstly, after selecting a position needing hammering, starting a bottom motor 5 of a bottom moving system, and enabling a portal frame 7 to move on a left bottom guide rail 2 and a right bottom guide rail 4 through the action of a gear 6 and a rack 3 to finish transverse positioning; starting a longitudinal motor 8 on the portal frame system, and enabling the hammering system 1 to move on the cross beam 10 through the action of a longitudinal lead screw 9 and a right sliding block 24 so as to finish longitudinal positioning; the linear motor 33 of the lifting system is started, the height of the hammering system 1 is adjusted through the butt strap 45, and vertical positioning is completed. It should be noted that the linear motor 33 is only one moving mode provided in this example, and the structural replacement of the hydraulic cylinder with the same function is also included in the protection scope of the present invention.
After the positioning is completed, the left motor 28 and the right motor 31 are started, so that the lower chain wheel shaft 41 rotates, and the lower chain wheel 40 drives the chain 25 to rotate in a clockwise direction. When the second stop 23 on the chain 25 rotates past the lower sprocket 40, the second stop 23 just contacts with the stop piece 43 on the hammer head assembly, and the hammer head assembly is dragged upwards by the stop piece 43, meanwhile, the spring 18 of the force adjusting assembly is compressed, when the chain 25 moves up to the upper sprocket 36, the second stop 23 is separated from the stop piece 43, and the hammer head assembly instantaneously drops under the action of gravity of the hammer head and the elasticity of the spring 18 to hammer the workpiece. At this time, the first stop 22 just rotates to the vicinity of the lower sprocket 40, the chain 25 continues to rotate, and the first stop 22 contacts the blocking piece 23 to drive the hammer head assembly to continue to move upwards, so as to prepare for the next hammering.
Continuous hammering can be realized by continuously running the left motor 28 and the right motor 31, the hammering time interval depends on the motor rotation speed, the diameter of the middle chain wheel 38 is slightly larger than that of the upper chain wheel 36 and the lower chain wheel 40, so that the distance between the first stop block 22 and the second stop block 23 can be adjusted, and when the rotation speed is high, the first stop block 22 rotating to the lower part can not rotate through the lower chain wheel 40 until the stop piece 23 falls to the lowest point after being separated from the second stop block 22 at the highest position, so that hammering components are not fallen to the lowest point, and hammering is influenced.
The upper motor 11 is started, the vertical screw rod 17 is rotated through the coupler 13, the upper and lower positions of the spring fixing seat 16 are changed by utilizing the action of screw rod nuts, and the compression amount of the spring 18 when the hammer head assembly is lifted to the highest point can be changed, so that the hammering force is adjusted.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the invention in any way, and any person skilled in the art may make modifications or alterations to the disclosed technical content to the equivalent embodiments. However, any simple modification, equivalent variation and variation of the above embodiments according to the technical substance of the present invention still fall within the protection scope of the technical solution of the present invention.
