Embodiment 1
[0043] like Figure 1-5 As shown, the present invention provides a processing equipment for large cylinder diameter steel piston ring groove, including a base 1, a column 2, a carriage 3, a worktable 4, a static electric spindle 5, a rotating spindle 7 and a motor 8, wherein,
[0044] A column 2 is arranged on the upper side of the base 1, a carriage 3 is slidably arranged on the column 2, a worktable 4 is slidably arranged on the carriage 3, a static electric spindle 5 is arranged on the workbench 4, and a grinding wheel 15 is arranged at the lower end of the electrostatic electric spindle 5. A rotating spindle 7 is set on the 1, a piston 21 is set on the rotating spindle 7, and the rotating spindle 7 is connected to the motor 8.
[0045] An on-line detection and tool setting mechanism 6 is arranged on the static electric spindle above the grinding wheel 15 , and the distance between the grinding wheel 15 and the piston is detected by the on-line detection and tool setting me...
Embodiment 2
[0057] A processing equipment for a large cylinder diameter steel piston ring groove, the structure is as described in Embodiment 1, the difference is that a fixing mechanism is arranged in the piston, and the fixing mechanism is as follows: Image 6 As shown, the piston is mounted to the rotating spindle by a fixed mechanism.
[0058] The fixing mechanism includes a pin shaft 16, a pull ring 17, a stop plate 18, a pull rod 19 and a rotary hydraulic cylinder 20. The rotary hydraulic cylinder 20 is arranged at the lower end of the rotating main shaft 7, and the rotary hydraulic cylinder 20 is provided with a pull rod 19. A stop plate 18 is provided, and the piston is clamped by the stop plate. A pull ring 17 is provided at the other end of the pull rod 19, and the pin shaft 16 passes through the pull ring 17 and is disposed on the pin holes 26 at both ends of the piston. The rotary hydraulic cylinder rotates and pulls the tie rod down, which in turn drives the pin shaft to move...
Embodiment 3
[0061] A processing equipment for a large cylinder diameter steel piston ring groove, the structure is as described in Embodiment 1, the difference is that a knife sharpener is arranged on one side of the rotating main shaft 7, and the knife sharpener is as Figure 7 As shown in the figure, when the grinding wheel is worn, it can be repaired directly on the sharpener, which is convenient and quick.
[0062] The grinder includes a grinder seat 22, a grinding port 27 is provided on the grinder seat 22, an upper end face cutter 24 of a grinding wheel is provided on the upper end of the grinding port 27, a bottom end face tool 25 of the grinding wheel is provided at the lower end of the grinding port 27, and a cylindrical surface of the grinding wheel is provided on the upper end of the grinding port 22 Cutter 23. The upper end face, lower end face and side face of the grinding wheel are repaired by the tool on the upper end face of the grinding wheel, the tool on the lower end fa...
