[0027] Please refer to Figures 1-5 , the present utility model is a runner structure of a chuck for a valve cone surface grinding machine, including a protective plate 101. A grinding head 102 is arranged on the top of the protective plate 101, and a hook 103 is fixedly connected to the side of the protective plate 101;

[0028] A clamping device 2 is arranged on the top of the protective plate 101. The clamping device 2 includes a fixed block 201. The bottom of the fixed block 201 is fixedly connected to the bottom of the protective plate 101. An electric telescopic rod 202 is fixedly connected to the top of the fixed block 201. The telescopic end of the electric telescopic rod 202 is fixedly connected to a fixing plate 203. A chute 204 is opened on the top of the fixing plate 203. A positioning rod 205 is arranged on the inner wall of the chute 204. An installation block 206 is fixedly connected to the circumferential surface of the positioning rod 205. A fixing rod 207 is fixedly connected to the side of the installation block 206. A positioning block 208 is fixedly connected to the side of the fixing rod 207.

[0029] The number of the fixing rods 207 is set to two and is symmetrically arranged along the vertical central axis of the protective plate 101. The number of the chutes 204 is set to two and is symmetrically arranged along the vertical central axis of the fixing plate 203, which can ensure the height accuracy and stability of the fixture during the clamping process, reduce the dependence on manual operation, and improve the consistency and accuracy of processing.

[0030] A runner 209 is arranged on the top of the protective plate 101. A hydraulic cylinder 210 is arranged on the top of the protective plate 101. One end of the hydraulic cylinder 210 is slidably connected to a force-bearing rod 212 through a piston, and the other end of the hydraulic cylinder 210 is slidably connected to a hydraulic rod 213 through a piston. One end of the hydraulic rod 213 is fixedly connected to a pressing plate 215, and one end of the force-bearing rod 212 is fixedly connected to a mounting plate 211.

[0031] A spring 214 is fixedly connected to the side of the hydraulic cylinder 210. One end of the spring 214 far from the hydraulic cylinder 210 is fixedly connected to the circumferential surface of the force-bearing rod 212. This flexibility enables the valve cone surface grinding machine to adapt to diverse processing requirements and reduces the equipment replacement and adjustment time.

[0032] The initial state of the spring 214 is a relaxed state. The mounting plate 211 is located on the movement trajectory of the fixed rod 207. This automatic clamping system can quickly and accurately clamp and release workpieces during the machining process, reducing the need for manual operation, improving production efficiency and consistency.

[0033] The number of positioning blocks 208 is set to two and they are symmetric with respect to the vertical central axis of the protective plate 101. This improves operational safety, reduces the risk of accidental damage, ensures machining consistency and quality, and reduces the defective product rate.

[0034] The number of rotating wheels 209 is set to two and they are symmetric with respect to the vertical central axis of the protective plate 101. This is crucial for ensuring the stability and accuracy of the workpiece during the machining process, especially in the case of high-precision machining.

[0035] A specific application of this embodiment is as follows: In this application, the electric telescopic rod 202 drives the fixed plate 203 to move, and then the movement of the fixed plate 203 drives the sliding groove 204 to move. When the inclined groove direction of the sliding groove 204 contacts the circumferential surface of the positioning rod 205, the two positioning rods 205 are in an open state. When the electric telescopic rod 202 drives the fixed plate 203 to contract, the movement of the fixed plate 203 drives the sliding groove 204 to move, and then the movement of the sliding groove 204 squeezes the positioning rod 205. The two positioning rods 205 move towards each other. The movement of the positioning rod 205 drives the two mounting blocks 206 to move towards each other, and then the movement of the mounting blocks 206 drives the two fixed rods 207 to move towards each other. The movement of the fixed rod 207 drives the positioning block 208 to move towards each other, realizing the function of fixedly clamping the valve. The movement of the fixed rod 207 squeezes the mounting plate 211 to move, and then the movement of the mounting plate 211 squeezes the force-bearing rod 212, causing the force-bearing rod 212 to move inward and squeeze the piston inside the hydraulic cylinder 210. The piston inside the hydraulic cylinder 210 pushes the liquid inside it, and the liquid inside the hydraulic cylinder 210 pushes another piston to move. The piston drives the hydraulic rod 213 to move, and the movement of the hydraulic rod 213 drives the pressing plate 215 to move, realizing pressing the valve into the space between the two rotating wheels 209, thereby fixedly clamping the valve from the bottom.
