[0033] Specifically, a material discharge cover 103a is provided at the edge of one side of the top of the finished product box 103, a material discharge box 105 is installed on one side of the top of the discharge cylinder 104, the bottom side of the material discharge box 105 is connected to the top side of the discharge cylinder 104 through an inclined tube 105a, a rotating plate 204 is sleeved on the middle part of the outer wall of the first rotating shaft 202a, a slide groove 204a is opened on the upper part of the interior of the rotating plate 204, and a second electric slide 205 is slidably connected inside the slide groove 204a, a second motor 206 is installed on one side of the outer wall of the second electric slide 205, the output shaft of the second motor 206 is connected to the second rotating shaft 206a through a coupling, and the other end of the second rotating shaft 206a passes through the bearing on the second electric slide 205 and is connected to the second grinding column 207.
[0034] Furthermore, the first electric slide 101, the drive box 102, the finished product box 103, the discharge barrel 104, the discharge box 105 and the structures thereon are all prior arts, so they will not be elaborated here. The operation of the first motor 202 can drive the first rotating shaft 202a to rotate under the action of the coupling, and make the first grinding column 203 and the rotating plate 204 on the outer wall rotate synchronously. The position of the second grinding column 207 can be adjusted under the action of the second electric slide 205 and the slide groove 204a.

[0036] Example 2
[0037] See also Figure 2 , Figure 4 and Figure 5 On the basis of Example 1, what is different from the first example is that: a clamping assembly 3 is provided, the clamping assembly 3 includes an electric push rod 301 and a mounting frame 302 installed at its telescopic end, a third motor 303 is installed inside the mounting frame 302, and the output shaft of the third motor 303 is connected to the threaded rod 303a through a coupling, which solves the problem that the existing grinding device for sealing valve seat maintenance clamps the valve seat by an electric clamp opened to the outside when in use, and this method will occupy a large amount of surrounding space when opened to the outside, which will affect the clamping range of the clamp, resulting in a smaller scope of application, and will also affect the spatial layout of subsequent devices.
[0038] Specifically, the other end of the threaded rod 303a passes through the bearing on the inner wall of the mounting frame 302 and the threaded hole on the moving block 305 and is connected to the bearing on the inner wall of the connecting plate 304 in sequence, and support blocks 306 are evenly spaced along the circumferential direction on the outer side between the moving block 305 and the connecting plate 304. The four ends of the connecting plate 304 are fixed on the outer wall of the mounting frame 302, and an anti-slip pad is bonded to the outer wall of the support block 306. The center positions of the outer walls on both sides of the support block 306 are respectively connected to the first connecting rod 306a and the second connecting rod 306b by hinges, the other end of the first connecting rod 306a is movably connected to the outer wall of the connecting plate 304 by a hinge, and the other end of the second connecting rod 306b is movably connected to the outer wall of the moving block 305 by a hinge.
[0039] Furthermore, the operation of the third motor 303 can drive the threaded rod 303a to rotate under the action of the coupling, and the connecting plate 304 is fixedly connected to the mounting frame 302. In order to adapt to various different environments and situations, the accompanying drawings do not show how the connecting plate 304 is connected to the mounting frame 302 to increase its scope of application. The external thread on the outer wall of the threaded rod 303a is spirally connected to the internal thread in the wall of the threaded hole on the moving block 305, which plays a transmission role. The movement of the support block 306 can be adjusted under the action of the first connecting rod 306a, the second connecting rod 306b and the hinge.
[0040] The operation process of this embodiment is as follows: multiple sealing valve seats that need to be polished are stored inside the discharge box 105, and the sealing valve seats fall into the discharge barrel 104 one by one through the inclined tube 105a, and are inserted into the outer side of the outer wall of the threaded rod 303a under the action of the inclined tube 105a. First, the sealing valve seats are stored vertically in the discharge box 105, that is, the hollow holes of the sealing valve seats are vertically arranged, so when the sealing valve seats move downward under the guidance of the inclined tube 105a, the hollow holes of the sealing valve seats move downward with the tilt of their body, so that the hollow holes of the sealing valve seats are inserted into the outer ends of the threaded rod 303a and multiple support blocks 306, and then the multiple support blocks 306 are used to support the inner wall of the hollow holes of the sealing valve seats, and the third motor 303 is started. The output shaft of the third motor 303 rotates to drive the threaded rod 303a to rotate through the coupling, and the threaded rod 303a rotates. The external thread on the outer wall of the threaded rod 303a is spirally matched with the internal thread in the wall of the threaded hole on the moving block 305, so when the threaded rod 303a rotates, it will drive the moving block 305 to move in the horizontal direction. Since four groups of support blocks 306 are arranged on the outer side of the threaded rod 303a, and the two ends of the support blocks 306 are movably connected to the connecting plate 304 and the moving block 305 through hinges with the first connecting rod 306a and the second connecting rod 306b respectively, when the support blocks 306 move, the support blocks 306 on all sides can be expanded outward under the action of the first connecting rod 306a and the second connecting rod 306b, and supported on the inner wall of the sealing valve seat, playing a role of limiting clamping, and supporting the inner wall of the sealing valve seat from the inside to play a role of limiting, and the clamping structure has a small operating range and will not affect the layout of the entire device, which is convenient for limiting clamping of sealing valve seats of different sizes.
