The stable clamping can be realized without arranging grooves at two ends of the piston rod, and a more reliable clamping scheme is provided for the piston rod which is not grooved. The first center 22 is driven to rotate by the first motor 23, and the efficient polishing treatment on the outer wall of the piston rod can be realized by combining polishing of the grinding wheel. The stable clamping mode ensures the safety in the polishing process and avoids the safety accident caused by the falling of the piston rod. In the process of clamping the piston rod, a proper clamping mode is selected according to the type of the piston rod and the polishing requirement. Then, the piston rod is placed in the fixed structure 2, and stable clamping of the piston rod is achieved by adjusting the movable support plate 24, the fastening three-jaw chuck 25 and the like. Then, the first motor 23 is started to drive the first center 22 to rotate, and the grinding wheel is started to polish the outer wall of the piston rod. In the polishing process, the position and the rotating speed of the grinding wheel can be adjusted according to the requirement so as to obtain the optimal polishing effect.
When the three-jaw chuck is used, when the two ends of a piston rod are required to be clamped, one end of the piston rod is firstly abutted against the first center 22, the jacking mechanism 26 is fixed through the three-jaw chuck 25, then the jacking mechanism 26 on the movable support plate 24 is abutted against the other end of the piston rod, the first center 22 and the end of the jacking mechanism 26 are respectively inserted into grooves at the end of the piston rod, then the piston rod is stably arranged between the first center 22 and the jacking mechanism 26, when the end of the piston rod is required to be clamped, firstly, one end of the piston rod is abutted against the first center 22, then the jacking mechanism 26 on the movable support plate 24 is abutted against the other end of the piston rod through the movable support plate 24, then the movable support plate 24 is continuously moved, the jacking mechanism 26 is moved towards the inside of the three-jaw chuck 25 under the extrusion of the piston rod, the movable support plate 24 is stopped until the end of the piston rod is inserted into the inside of the three-jaw chuck 25, and then the end of the piston rod is stably arranged on the three-jaw chuck 25 through fastening the three-jaw chuck 25, so that the clamping stability of the piston rod is ensured.

In order to conveniently adjust the position of the movable support plate 24, an adjusting structure 3 for adjusting the position of the movable support plate 24 is arranged on the base 1, the adjusting structure 3 comprises a guide frame plate 31 sleeved on the movable support plate 24, a driving screw rod 32 which is inserted on the movable support plate 24 in a threaded manner and is rotationally connected with the guide frame plate 31, and a second motor 33 which is fixedly arranged on the guide frame plate 31 and is used for driving the driving screw rod 32 to rotate, and the fixed support plate 21 is fixed at one end of the guide frame plate 31. The second motor 33 drives the driving screw rod 32 to rotate, so that the position of the movable support plate 24 can be accurately regulated, and the requirements of different clamping positions of the piston rod are met. The design of the adjusting structure 3 makes the adjustment of the position of the movable support plate 24 simple and quick, and reduces the operation difficulty and the labor intensity. The guide frame plate 31 provides stable guide for the movement of the movable support plate 24, ensuring stability and reliability in the adjustment process.

By controlling the steering and rotational speed of the second motor 33, precise control of the direction and speed of movement of the movable support 24 can be achieved. When the movable support plate 24 moves to a required position, the rotation of the second motor 33 is stopped, and at the moment, the supporting mechanism 26 on the movable support plate 24 can be matched with the first center 22 on the fixed support plate 21, so that the piston rod can be clamped and fixed. In the clamping process, a proper clamping mode can be selected according to the type of the piston rod and the polishing requirement, such as two-center clamping or three-jaw chuck 25 and the center matched clamping.
Example 2
Unlike embodiment 1, in order to facilitate the movement of the piston rod in a direction approaching the grinding wheel, the base 1 is provided with a driving structure 4 for driving the guide frame plate 31 to rotate circumferentially, and the driving structure 4 includes two support plates 41 symmetrically fixedly provided on the base 1, a hinge plate 42 hinged inside the support plates 41 and fixedly connected to the lower end of the guide frame plate 31, and a worm gear combiner 43 fixedly installed on one of the support plates 41, and a worm gear shaft of the worm gear combiner 43 is fixedly connected to a hinge shaft of the hinge plate 42. Can carry out circumference to the guide frame board 31 through driving structure 4 and adjust, conveniently make the piston rod of fixing on the guide frame board 31 to be close to or keep away from the direction removal of emery wheel, then conveniently polish the outer wall of piston rod. The adjustment of the position of the piston rod becomes simple and quick through the design of the driving structure 4, and the operation difficulty and the labor intensity are reduced. The design of the support plate 41 and hinge plate 42 provides stable support and guidance for the movement of the guide frame plate 31 and piston rod, ensuring stability and reliability during adjustment. The design of the drive structure 4 enables the device to be suitable for piston rods with different lengths and diameters, and improves the universality and adaptability of the device. When circumferential adjustment of the position of the piston rod is required, the worm and gear combiner 43 is first activated to drive the hinge plate 42 to hinge about the support plate 41. Since the hinge plate 42 is fixedly connected to the lower end of the guide frame plate 31, the guide frame plate 31 and the piston rod fixed thereto are also adjusted in the circumferential direction in accordance with the rotation of the hinge plate 42. By controlling the steering and rotational speed of the worm gear combiner 43, precise control of the direction and speed of movement of the piston rod can be achieved. During grinding, the worm and gear combiner 43 may be configured to rotate in a forward direction, moving the piston rod in a direction toward the grinding wheel until the piston rod contacts the grinding wheel and begins grinding. When the piston rod is polished, the worm and gear combiner 43 is driven in the reverse direction, so that the piston rod moves away from the grinding wheel, and the whole polishing process is completed.
The worm shaft of the worm gear and worm combiner 43 is fixedly connected with a hand wheel 431. The worm and gear combiner 43 is conveniently driven by the hand wheel 431 to drive the hinged plate 42 to hinge and rotate around the supporting plate 41, so that the piston rod can be enabled to circumferentially rotate, and the piston rod can be conveniently moved to a direction close to the grinding wheel.
