[0028] The upper end of the U-shaped connecting rod 29 is provided with a plurality of balls II 211. The balls I 1973 and II 211 facilitate the sliding of the clamping plate 197 and the U-shaped connecting rod 29 on the surface of the composite material 3 product to avoid scratches caused by friction.

[0029] The outer end of the U-shaped connecting rod 29 away from the fixing plate 25 is set as an arc surface, and the end is provided with an arc groove, and the roller II 211 is connected to the arc groove through the shaft II 212.

[0030] A method for using a composite material molding fixture, the method comprising the following steps:

[0031] Step 1: Place the composite material 3 on the U-shaped connecting rod 29, and then rotate the threaded cylinder 193 to clamp the composite material 3 with the U-shaped connecting rod 29 and the clamping plate 197;

[0032] Step 2: After grinding, start the motor 21 to drive the composite material 3 to flip 180 degrees for easy grinding.

[0033] The working principle of the present invention is: when using the device, one end of the composite material 3 product is pressed against the side of one of the limit blocks 198, and then the limit block 198 is pushed to move, and the limit block 198 drives the screw rod II 191 connected thereto to move. Since the screw rod II 191 is slidably matched with the insertion rod 26, and the insertion rod 26 is arranged horizontally, the screw rod II 191 drives the connecting ring 192 and then drives the connecting rod 110 to move in the horizontal direction, and the connecting rod 110 drives the upper end of the rotating rod 17 to move toward the direction of the support rod 12, and the lower end of the rotating rod 17 drives the slide plate 15 to slide downward and compress the spring I 13; the slide plate 15 moves downward, drives the other rotating rod 17 to move, and then drives the other screw rod II 191 to move, The distance between the two screw rods II 191 is increased. When the distance between the two screw rods II 191 is greater than the length of the composite material 3 product, the composite material 3 product is placed on the upper ends of the two U-shaped connecting rods 29. Then, under the action of the elastic force of the spring I 13, the slide plate 15 is pushed upward, and then the screw rod II 191 is driven to move through the rotating rod 17, the connecting rod 110, and the connecting ring 192, and the composite material 3 product is clamped by the limit block 198; then the screw rod I 14 is rotated, and the screw rod I 14 moves downward relative to the slide plate 15, and finally cooperates with the threaded hole on the base 11 to fix the relative position of the slide plate 15 and the base 11, and then fix the position of the screw rod II 191 to avoid random shaking during grinding;

[0034] Then, the threaded cylinder 193 is rotated, and the threaded cylinder 193 moves downward on the screw rod II 191, thereby driving the rotating ring 194, the connecting rod I 195, the connecting rod II 196 and the clamping plate 197 to move downward, so that the clamping plate 197 is close to the upper end surface of the composite material 3 product;

[0035] During grinding, when the grinding tool moves to contact with the splint 197, the grinding tool will drive the belt 1975 to move through friction, and then drive the roller I 1973 to rotate, reducing the damage of the grinding tool to the splint 197. At the same time, when the grinding tool moves on the upper end of the composite material 3 product, it will push the splint 197 to move together, so that the splint 197 drives the rotating ring 194 to rotate relative to the threaded cylinder 193 through the connecting rod I 195 and the connecting rod II 196. The rotating ring 194 rotates and drives the connecting rod I 195 and the connecting rod II 1973 to rotate. 6 The other clamping plates 197 connected to the outside of the rotating ring 194 move to the upper end of the composite material 3 product. The length of the clamping plates 197 is greater than the diameter of the grinding disc on the grinding tool, so that the grinding disc pushes one of the clamping plates 197 to move, and when the clamping plate 197 is not separated from the upper end surface of the composite material 3 product, the other clamping plate 197 moves to the upper end of the composite material 3 product, so that the clamping plate 197 can automatically move to the upper end of the composite material 3 product, avoiding the need for manual control by workers when flipping the composite material 3 product, and is more convenient to use;

[0036] After the upper end surface of the composite material 3 product is polished, the motor 21 is started, and the motor 21 drives the rotating shaft 23 to rotate, and then drives the connecting plate 24 to rotate, the connecting plate 24 drives the fixing plate 25 to rotate, the fixing plate 25 drives the plug rod 26 and the U-shaped connecting rod 29 to rotate, the plug rod 26 drives the screw Ⅱ191 to rotate, and after rotating 180°, the motor 21 is turned off; at this time, the U-shaped connecting rod 29 is located at the upper end of the composite material 3 product, when the polishing tool is polishing, it contacts the end of the U-shaped connecting rod 29 with the roller Ⅱ211, drives the roller Ⅱ211 to rotate, and then pushes the polishing tool along the setting direction of the U-shaped connecting rod 29, so that the polishing tool drives the U-shaped connecting rod 29 and the plug rod 26 to move into the corresponding slideway 27, and the plug rod 26 compresses the spring Ⅱ28. After the polishing is completed, the polishing tool is removed, and the plug rod 26 and the U-shaped connecting rod 29 are pushed to move to the original position under the action of the spring Ⅱ28.
