[0030] A method for using a post-molding grinding device for composite material manufacturing, the method comprising the following steps:

[0031] Step 1: placing the composite material 9 on the stage 5;

[0032] Step 2: Then the upper horizontal end of the Z-shaped slide bar 69 is disengaged from the slot 86, and then the control device 6 and the grinding device 7 are moved downward until the grinding block 77 and the wheel I 71 contact the upper end surface of the composite material 9, and then the upper horizontal end of the Z-shaped slide bar 69 is inserted into the corresponding slot 86;

[0033] Step 3: Start motor I 76 to drive the grinding block 77 to rotate; start a motor II 16 to drive the control device 6, the grinding device 7 and the connecting device 8 to slide along the moving direction of the connecting rod 15, thereby driving the grinding block 77 to grind the surface of the composite material 9.

[0034] The working principle of the present invention is: the composite material 9 is placed on the stage 5; the insertion rod 83 is pulled out, and the connecting ring 82 is rotated to drive the vertical rod 85 to move to the front end of the travel direction, thereby driving the grinding device 7 and the control device 6 to rotate together, and the control device 6 moves to the front end of the travel direction, and then the insertion rod 83 is inserted into the limiting connecting ring 82 to rotate;

[0035] Then, the wheel II 61 is pushed upward, so that the wheel II 61 drives the sliding rod 62 to move upward, thereby compressing the spring II 66, and driving the slider 67 upward through the elastic force, so that the connecting hole 612 is exposed and connected to the inside of the fixed cylinder 65, and the Z-shaped sliding rod 69 moves upward under the elastic force of the spring IV 613. Figure 1The right side of the state shown is moved, the upper horizontal end of the Z-shaped slide bar 69 is disengaged from the slot 86, and then the control device 6 and the grinding device 7 are moved downward until the grinding block 77 and the wheel I 71 contact the upper end surface of the composite material 9, and then the wheel II 61 is released, so that the wheel II 61 is closely pressed against the upper end surface of the composite material 9 under the action of the spring I 64 and the spring II 66. The elastic force of the spring I 64 is greater than the elastic force of the spring II 66, and the spring II 66 drives the slide bar 7 to move downward, pushing the lower horizontal end of the Z-shaped slide bar 69 to move to the left, so that the upper horizontal end of the Z-shaped slide bar 69 is inserted into the corresponding slot 86;

[0036] Start the motor I 76 to drive the grinding block 77 to rotate; start a motor II 16, the motor II 16 drives the corresponding screw 13 to rotate, and then drives the corresponding connecting rod 15 to move, the connecting rod 15 drives the connecting block 14 to move, and then drives the control device 6, the grinding device 7 and the connecting device 8 to slide along the moving direction of the connecting rod 15, and then drives the grinding block 77 to grind the surface of the composite material 9;

[0037] When the wheel I 61 moves to the downward slope of the composite material 9 (such as Figure 8 As shown in the figure, since the control device 6 is at the front end of the travel direction of the grinding block 77, when the grinding block 77 is still on the plane of the composite material 9, the wheel I 61 first contacts the downward inclined surface, and since the spring I 64 is in a compressed state, the spring I 64 drives the wheel I 61 to move downward along the inclined surface, thereby driving the sliding rod 62 to move downward, the sliding rod 62 drives the spring II 66 to move downward, the spring II 66 drives the slider 67 to move downward, and the slider 67 drives the spring III 68 to stretch, so that the connecting hole 612 is exposed above the slider 67, and under the action of the spring IV 613, the horizontal end below the Z-shaped slider 69 moves to the right, driving the horizontal end above the Z-shaped slider 69 to disengage from the slot 86. With the continuous movement, due to the wheel I 71 and the grinding block There is a gap between the wheels 1 and 77, so when the wheel 1 71 contacts the inclined surface of the composite material 9, the motor 1 76, the motor bracket 74 and the slide bar 75 are driven to move downward under the action of gravity, and the grinding block 77 is suspended at the same time, so as to avoid the edge of the grinding block 77 from contacting the inclined surface during the downward movement, resulting in damage to the inclined surface; when the wheel 1 71, the grinding block 77 and the wheel 2 61 contact the plane below the inclined surface at the same time, the slide bar 62 pushes the spring 2 66 to compress, and the spring 2 66 pushes the slide bar 67 to move upward, and the slide bar 67 pushes the inclined surface of the horizontal end below the Z-shaped slide bar 69, so that the Z-shaped slide bar 69 moves to the left, so that the horizontal end above the Z-shaped slide bar 69 is inserted into the corresponding slot 86, so as to achieve the purpose of automatically lowering the height of the grinding block 77;

[0038] The Z-shaped slide bar 69 is limited to move up and down through the slot 86 on the vertical rod 85, thereby limiting the upward and downward movement of the fixed cylinder 65. The fixed cylinder 65 is fixedly connected to the cross bar 79, which can limit the upward and downward movement of the grinding device 7, thereby preventing the grinding block 77 from moving upward when encountering a protrusion, resulting in a poor grinding effect.

[0039] When the wheel Ⅰ61 moves to the upward inclined surface of the composite material 9 (such as Fig. 9 As shown in the figure, wheel I 61 first contacts the upward inclined surface. Since the Z-shaped slide bar 69 is located in the slot 86, the fixed cylinder 65 cannot move upward. Therefore, wheel I 61 drives the slide bar 62 to move upward, compressing spring I 64 and spring II 66. Spring II 66 drives the slider 67 to move upward. The slider 67 compresses spring III 68, so that the connecting hole 62 is exposed below the slider 67. The Z-shaped slide bar 69 is separated from the slot 86 by the action of spring IV 613, and no longer restricts the upward and downward movement of the fixed cylinder 65 (and a gap is left between the grinding block 77 and the upward inclined surface). At this time, the fixed cylinder 65 is driven to move upward by the elastic force of springs I 64, II 66 and III 68, and the fixed cylinder 65 drives the motor bracket 74, motor I 76 and the grinding block through the cross bar II 79. 77 moves upward relative to the connecting cylinder 81, and at the same time, the fixed cylinder 65 moves upward to drive the Z-shaped slide bar 69 to move upward, so that the horizontal end below the Z-shaped slide bar 69 contacts the slider 67, and pushes the Z-shaped slide bar 69 to move leftward, so that the horizontal end above the Z-shaped slide bar 69 is inserted into the corresponding slot 86, thereby preventing the fixed cylinder 65 and the grinding block 77 from moving downward, and the grinding block 77 is suspended in the air to avoid contact with the upward inclined surface and cause damage; repeating the above operation can move on the upward inclined surface, when the wheel I 61 passes the upward inclined surface and moves to the plane, because the fixed cylinder 65 is restricted by the Z-shaped slide bar 69 to move up and down, the height of the grinding block 77 is the same as the lowest point height of the wheel I 61, and the plane can be directly ground as it continues to move;

[0040] When the wheel Ⅰ61 moves to the upward protrusion of the composite material 9 (such as Fig.10 As shown); wheel Ⅰ61 moves upward a short distance, compressing spring Ⅰ64 and spring Ⅱ66. Since wheel Ⅰ61 drives the sliding rod 62 to move a short distance, the deformation of spring Ⅱ66 is small, and the distance of driving the slider 67 to move upward is small, so that the horizontal end below the Z-shaped sliding rod 69 is still in contact with the slider 67, and the upward and downward movement of the fixed cylinder 65 is restricted, thereby restricting the upward and downward movement of the grinding block 77, so that the lower end surface of the grinding block 77 is kept at the same height, avoiding the upward and downward movement of the grinding block 77, resulting in poor grinding effect of the raised position on the plane; when wheel Ⅰ61 passes over the raised position on the plane, it returns to its original state under the action of spring Ⅰ64;

[0041] At the same time, the worker only needs to manually polish the inclined surface and the plane close to the inclined surface on the composite material 9, and the two work at the same time, thereby improving work efficiency.
