DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-2 This application is described in further detail.

[0019] A grinding mechanism 3 is symmetrically arranged on both sides of the clamping mechanism, and the grinding mechanism 3 includes a servo linear guide slide 31, a bracket 32, a steering gear 33, a turntable 34, a mounting frame 35, a grinding motor 36, a grinding stone 37 and a distance sensor 38. The servo linear guide slide 31 is fixed to the workbench 1 and is arranged along the length direction of the piston rod. The bracket 32 ​​is fixed to the slide of the servo linear guide slide 31. The turntable 34 is rotatably connected to the bracket 32. The steering gear 33 is fixed in the bracket 32 ​​and is used to drive the turntable 34 to rotate. The mounting frame 35 is fixed on the turntable 34. The grinding motor 36 and the distance sensor 38 are respectively fixed on the mounting frame 35. The distance sensor 38 can be coaxially arranged with the piston rod. The grinding stone 37 is detachably fixed on the output shaft of the grinding motor 36;

[0020] An electric control cabinet 4 is also provided on the workbench 1, in which a single chip microcomputer (not shown in the figure) is installed. The distance measuring sensor 38 is electrically connected to the input end of the single chip microcomputer, and the servo linear guide slide 31 and the steering gear 33 are electrically connected to the output end of the single chip microcomputer respectively.

[0023] The implementation principle of a double-head grinding device for processing a cylinder piston rod forging in the embodiment of the present application is as follows:

At this time, the distance sensors 38 located at both ends of the piston rod forging respectively measure the position of the end of the piston rod forging, and transmit the position signal to the single-chip microcomputer. The servo 33 drives the turntable 34 to rotate so that the grinding motor 36 is facing the piston rod forging. The single-chip microcomputer controls the number of rotations of the servo motors in the servo linear guide slides 31 on both sides according to the position signal, so that the grinding stone 37 just abuts against the end face of the piston rod forging. The grinding stones 37 on both sides can grind the two end faces of the piston rod forging respectively, with good grinding effect and high efficiency.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
