[0024] Refer to the instruction manual Figure 1-5 The utility model provides a rapid repair device for the surface of an injection molded part, comprising a mounting shell 1 and a packaging shell 2 provided on the top of the mounting shell 1. A processing table 3 for placing the injection molded part is provided inside the mounting shell 1, and a positioning component for fixing and limiting the injection molded part is provided outside the processing table 3;

[0025] like Figure 4 and 5 As shown, the positioning assembly includes a groove 4 opened at the bottom of the processing table 3, and a threaded rod 5 is provided inside the groove 4 and is movably connected by a bearing. The threads at both ends of the threaded rod 5 are in opposite directions, and the external ends of the threaded rod 5 are threadedly connected to a movable seat 6. A connecting bracket 7 is installed on the side away from the bottom ends of the two movable seats 6, and the end of the connecting bracket 7 away from the movable seat 6 extends to the top of the processing table 3 and is installed with a positioning member 8; a packaging member 9 is installed on the side of the bottom of the processing table 3 corresponding to the groove 4, and the packaging member 9 is sleeved on the two movable seats 6 and the two connecting brackets. 7, a mounting groove 10 is provided on one side of the groove 4 corresponding to one end of the processing table 3, and a motor 11 is installed inside the mounting groove 10. The output shaft of the motor 11 passes through the processing table 3 and is fixed to the threaded rod 5; a dustproof net 12 is provided on the side of the motor 11 away from the processing table 3 and installed inside the mounting groove 10. Through the connection between the output shaft of the motor 11 and the threaded rod 5, the motor 11 can drive the two movable seats 6 on the threaded rod 5 to move inward or outward at the same time, thereby adjusting the distance between the two positioning parts 8 according to the size of the injection molded part.

[0026] like Figure 3As shown, a support shaft 13 movably connected by a bearing is installed on the top of the inner cavity of the packaging shell 2, and a polishing piece 14 for repairing the injection molded part is installed at the bottom end of the support shaft 13; a servo motor 22 is installed on the top of the packaging shell 2, and the output shaft of the servo motor 22 passes through the packaging shell 2 and is fixed to the top of the support shaft 13. Through the connection between the output shaft of the servo motor 22 and the support shaft 13, the servo motor 22 can drive the polishing piece 14 to rotate, and the surface of the injection molded part is repaired by the polishing piece 14. A fan 15 is provided on the top of the polishing piece 14, which is sleeved on the outside of the support shaft 13 and is used to blow away debris adhered to the surface of the processing table 3. Through the connection between the fan 15 and the support shaft 13, the fan 15 can be rotated with the support shaft 13, so that the fan 15 can blow away debris adhered to the surface of the injection molded part or the surface of the processing table 3, thereby avoiding the accumulation of debris affecting the processing accuracy or causing pollution to the surface of the processing table 3.

[0027] like Figure 1-3 As shown, a mounting frame 16 is installed on the outside of the bottom end of the mounting shell 1, and a packaging frame 17 is provided on the top of the mounting frame 16 and is sleeved on the outside of the packaging shell 2, and a plurality of spaced electric push rods 18 are installed between the mounting frame 16 and the packaging frame 17. By extending and contracting the electric push rods 18, the height of the packaging shell 2 can be adjusted up and down, thereby facilitating the staff to adjust the connection between the packaging shell 2 and the mounting shell 1.

[0028] like Figure 2 As shown, an exhaust fan 19 is provided at the rear side of the bottom end of the mounting shell 1, and an air duct 23 for connecting to the mounting shell 1 is installed at the front end of the exhaust fan 19, and a fixing bracket 20 for connecting to the bottom of the mounting shell 1 is installed at the bottom end of the exhaust fan 19. The debris in the mounting shell 1 is discharged through the air duct 23 by the exhaust fan 19, thereby preventing the debris from accumulating inside the mounting shell 1.

[0029] like Figure 3 and 4 As shown, a plurality of pillars 21 for connecting to the bottom of the inner cavity of the mounting shell 1 are installed at the bottom of the processing table 3. The arrangement of the plurality of pillars 21 can enhance the stability of the processing table 3.

[0030] First, the staff places the injection molded part on the processing table 3, and then drives the threaded rod 5 by the motor 11 to drive the two movable seats 6 limited by the groove 4 to move inward at the same time. The two movable seats 6 then drive the positioning members 8 on the corresponding connecting brackets 7 to move inward to clamp and fix the injection molded part, thereby ensuring the stability of the injection molded part when it is repaired. The threaded rod 5, connecting bracket 7 and movable seat 6 and other structures in the positioning assembly are all arranged at the bottom of the processing table 3 and encapsulated inside the encapsulation 9. This can prevent debris from adhering to the performance stability of the positioning assembly, and also make the surface of the processing table 3 smooth, improving the convenience of handling debris.

[0031] After the injection molded part is fixed, the package shell 2 is moved downward by the contraction of the electric push rod 18, thereby allowing the polishing piece 14 to contact the injection molded part. Then, the servo motor 22 is started to drive the polishing piece 14 and the fan 15 on the support shaft 13 to rotate. The polishing piece 14 polishes and repairs the injection molded part, while the fan 15 blows away the debris adhering to the surface of the injection molded part and the surface of the processing table 3, preventing the debris from adhering to the surface of the injection molded part and affecting the repair accuracy of the injection molded part, and also preventing the debris from accumulating on the surface of the processing table 3 and causing contamination.

[0032] The blown debris is then discharged to the outside of the installation shell 1 through the air duct 23 on the exhaust fan 19, thereby preventing the debris from accumulating inside the installation shell 1 and reducing the workload of the staff in subsequent maintenance of the installation shell 1.

[0033] After the polishing process is completed, the electric push rod 18 pushes the packaging shell 2 connected to the packaging frame 17 to move upward, so that the packaging shell 2 can be separated from the mounting shell 1, making it easier for the staff to take the repaired injection molded part on the processing table 3.

[0034] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
