However, the existing FRP has different shapes. When performing repeated polishing operations, the operator needs to use a polishing device to gradually polish the outer side of the workpiece, which will slow down the polishing efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] The existing FRP has different shapes. When repeated grinding is performed, the operator needs to use a grinding device to gradually grind the outside of the workpiece, which will slow down the grinding efficiency. Figure 1-Figure 3 This embodiment provides a multi-station grinding machine for glass fiber reinforced plastic membrane shells, which solves the technical problem of a narrow single-time grinding range. The device includes a support table 1 as a support base, a wrap-around grinding mechanism 2 for grinding a workpiece disposed on the support table 1, and a clamping and fixing mechanism 3 for clamping and fixing the workpiece. The workpiece is clamped and fixed by the clamping and fixing mechanism 3, and the workpiece is polished by the wrap-around grinding mechanism 2.

[0025] In order to be able to grind workpieces of more specifications and improve the efficiency of single grinding. The wrapped grinding mechanism 2 includes a support frame 201 fixedly connected to the middle of the top of the support table 1, and a transmission motor 202 is installed on one side of the top of the support frame 201 through a base. The top of the support table 1 is fixedly connected to a fixed frame 203 below the support frame 201, and the middle of the inner side of the fixed frame 203 is rotatably connected to an active transmission pulley 204. The outer ends of the fixed frame 203 are fixedly connected to buffer slide rails 205, and the inner side of the buffer slide rails 205 is slidably connected to a slider rod 206. The ends of the two slider rods 206 are both connected to a connecting frame 208, and the connecting frame 208 is rotatably connected to a driven pulley 209 at one end away from the buffer slide rail 205. A return spring 207 is connected between the slider rod 206 and the inner wall of the buffer slide rail 205. The active transmission pulley 204 and the two driven pulleys 209 are connected by a grinding belt 210, and the transmission end of the transmission motor 202 passes through the support frame 201 and is connected to the top of the active transmission pulley 204.

[0026] First, the workpiece is clamped and fixed by the clamping and fixing mechanism 3, and then the driving transmission motor 202 is started to drive the active transmission pulley 204 connected to its transmission end to rotate, and the active transmission pulley 204 will drive the other two driven pulleys 209 to rotate through the grinding belt 210 sleeved on its outer side, thereby realizing the grinding of the clamped and fixed workpiece.

[0027] Example 2

[0028] On the basis of Example 1, Example 1 solves the technical problem of narrow single grinding range, but there is still the problem of limited clamping parts. Figure 1-Figure 3 As shown, the specific implementation process is as follows: In order to fully utilize the power transmitted by the wrapped grinding mechanism 2, the clamping and fixing mechanism 3 includes a support tray 301 rotatably connected to one side of the top of the support table 1. The bottom ends of the support tray 301 and the active transmission pulley 204 pass through the support table 1 and are fixedly connected to a connecting bevel gear rod 302. The bottom end of the support table 1 is rotatably connected to a connecting gear rod 303 through a bracket. The two ends of the connecting gear rod 303 are respectively engaged with two connecting bevel gear rods 302.

[0029] In order to be able to clamp and fix according to different workpieces. The top of the support frame 201 is spirally connected to the side of the transmission motor 202 through a threaded sleeve with an adjusting screw 305, the bottom end of the adjusting screw 305 is rotatably connected to the clamping top plate 304, and the top end of the adjusting screw 305 is fixedly connected to a turntable 306. First, the operator places the workpiece on the top of the support tray 301, and then drives the adjusting screw 305 fixed at its bottom end to spirally move downward by rotating the turntable 306, thereby driving the clamping top plate 304 rotatably connected at its bottom end to clamp and fix the top of the workpiece. During the operation of the wrapped grinding mechanism 2, the active transmission pulley 204 will drive the connecting bevel gear rod 302 connected to its bottom end to rotate, and the connecting bevel gear rod 302 will drive the connecting gear rod 303 meshing with it to rotate, and the connecting gear rod 303 will drive another connecting bevel gear rod 302 to rotate. The connecting bevel gear rod 302 will drive the supporting tray 301 fixed to its top to rotate, and at the same time drive the workpiece and the clamping top plate 304 to rotate. Due to the irregular shape of the workpiece, the raised part on the outside of the workpiece will interfere with the grinding belt 210 during the rotation of the workpiece. At that time, the grinding belt 210 will sink inward and pull the two driven pulleys 209 connected to it inward for clamping and moving. The driven pulley 209 will drive the slider rod 206 connected to it through the connecting frame 208 to clamp and slide inside the buffer slide rail 205, thereby adapting to the shape of the irregular workpiece. At the same time, large-area contact grinding can improve the grinding efficiency, and after the raised part of the workpiece rotates away from the grinding belt 210, the return spring 207 inside the buffer slide rail 205 will push the slider rod 206 to reset.
