Description

Technical Field

[0001] This invention belongs to the field of civil defense door technology, specifically relating to a processing equipment and processing method for a civil defense door leaf pivot shell. Background Technology

[0002] Civil defense doors are the doors at the entrances and exits of civil defense projects. Civil defense doors are classified in a relatively clear way, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, and other civil defense equipment. Because of the heavy weight of the air-raid shelter door, it is connected to the wall by a hinge to facilitate opening and closing. The outer wall of the hinge needs to be fitted with a hinge shell, which is connected to the wall, while the inner wall is connected to the hinge of the air-raid shelter door.

[0003] Because the shaft housing is subjected to a large force and its interior is constantly rubbing against the shaft, the inner wall of the shaft housing needs to be polished using processing equipment. However, after polishing, the shaft housing still needs to be removed and transported to another location for electroplating or other wear-resistant treatment of its inner wall. Summary of the Invention

[0013] In another aspect, the present invention provides a method for processing a protective shell for the hinge of a civil defense door leaf, which is implemented using the aforementioned processing equipment for the protective shell of the hinge of a civil defense door leaf, and the steps are as follows: S1, the rotating shaft housing body is placed between the fitting cones in the second clamping frame and the first clamping frame for fixation. The rotating disk rotates and generates centrifugal force, causing the rotating disk to drive the grinding ring to move outward and fit against the inner wall of the rotating shaft housing body to grind the rotating shaft housing body. S2, After the inner wall of the rotating shaft housing is polished, the clamping structure moves the rotating shaft housing to the top of the electroplating solution placement box, and the electric telescopic rod moves the electroplating solution placement box upward, so that the chromium inside the electroplating solution placement box comes into contact with the inner wall of the rotating shaft housing, improving the wear resistance of the inner wall of the rotating shaft housing.

Beneficial effects The technical solution provided by this invention has the following advantages compared with the prior art: The present invention can clamp the rotating shaft housing body through the clamping structure. Then the clamping structure can move the rotating shaft housing body to the top of the electroplating solution placement tank at different positions, so that the rotating shaft housing body with the inner diameter polished can enter the interior of the electroplating solution placement tank for electroplating, thereby increasing the wear resistance and corrosion resistance of the rotating shaft housing body. When the inner diameter grinding structure rotates, the rotating disk generates centrifugal force, causing the grinding ring on the outer wall of the rotating disk to move outward and contact the inner wall of the rotating shaft housing. The drive shaft is a hollow tube, and one end of the drive shaft is connected to the coolant delivery pipe structure, allowing the coolant to enter the interior of the inlet tank and spray out to clean the grinding debris.

The clamping structure 8 includes a crossbar 801 with threaded holes on both sides inside the crossbar 801. The crossbar 801 is connected to the first transmission screw 7 through the threaded holes. The two sides of the crossbar 801 are rotatably connected to the second transmission screw 802. The bottom of the second transmission screw 802 is rotatably connected to the roller 803. The bottom of the roller 803 is in contact with the inner wall of the guide groove 2. The top of the second transmission screw 802 is provided with a servo motor 804.

[0022] Furthermore, in the above technical solution, an electroplating solution placement box 5 is provided inside the mounting groove 3, and electric telescopic rods 4 are provided on both sides of the electroplating solution placement box 5. The electric telescopic rods 4 are bolted to the outer wall of the housing 1. The electric telescopic rods 4 can drive the electroplating solution placement box 5 to move upward, and then the electroplating solution inside the electroplating solution placement box 5 comes into contact with the inner wall of the rotating shaft protective housing body 9.

[0023] Furthermore, in the above technical solution, a slide bar 805 is provided on one side of the crossbar 801, and a first clamping frame 806 and a second clamping frame 807 are provided between the slide bar 805 and the second transmission screw 802. A contact cone 808 is provided on the inner side of the first clamping frame 806 and the second clamping frame 807. The threads at both ends of the second transmission screw 802 on one side of the crossbar 801 have opposite directions, and the threads at both ends of the second transmission screw 802 respectively cooperate with the first clamping frame 806 and the second clamping frame 807. A lifting frame 10 is provided on the outer wall of the second transmission screw 802 on the other side of the crossbar 801. A drive motor 11 is provided in the middle of the frame 10. The output end of the drive motor 11 is provided with a drive gear 12. The servo motor 804 drives the second transmission screw 802 to rotate, so that the second transmission screw 802 drives the first clamping frame 806 and the second clamping frame 807 to move relative to each other. Then, the fitting cones 808 in the first clamping frame 806 and the second clamping frame 807 fit with both ends of the rotating shaft protective shell body 9 to fix the rotating shaft protective shell body 9. There are multiple fitting cones 808 and the fitting cones 808 are set to be conical. While reducing the contact area between the fitting cones 808 and the rotating shaft protective shell body 9, the rotating shaft protective shell body 9 is stably fixed.

[0024] Furthermore, in the above technical solution, a drive shaft 13 is rotatably connected to one side of the lifting frame 10. A driven gear 14 is provided on the outer wall of the drive shaft 13. The driven gear 14 meshes with the driving gear 12. A retaining ring 15 is provided at the bottom of the driven gear 14. The driven gear 14 is connected to the inner diameter grinding structure 16 through the retaining ring 15. The top of the drive shaft 13 is connected to the connecting pipe through a rotary sealing ring. One end of the connecting pipe is connected to a water pump. The water pump can draw coolant into the interior of the drive shaft 13 and pump it out through the inner diameter grinding structure 16 to clean the debris produced by the inner diameter grinding structure 16.

[0025] Furthermore, in the above technical solution, the inner diameter grinding structure 16 includes a rotating disk 1601, with a liquid inlet groove 1602 formed in the middle of the top of the rotating disk 1601. A retaining groove 1603 is formed inside the liquid inlet groove 1602, and the retaining groove 1603 fits against the retaining ring 15. A liquid outlet groove 1604 is formed inside the rotating disk 1601, with one end connected to the liquid inlet groove 1602. Limiting grooves 1605 are formed at the top and bottom of the rotating disk 1601, and a return spring 1606 is provided inside the limiting groove 1605. One end of the positioning spring 1606 is provided with a movable block 1607, which is slidably connected to the inside of the limiting groove 1605. The outer wall of the movable block 1607 is provided with a grinding ring 1608, which is in contact with the inner wall of the rotating shaft housing body 9. During the rotation of the rotating disk 1601, the rotating disk 1601 generates centrifugal force, and then the rotating disk 1601 drives the movable block 1607 to slide on the inner wall of the limiting groove 1605 and squeeze the return spring 1606, so that the grinding ring 1608 moves outward to fit against the inner wall of the rotating shaft housing body 9.

[0026] In another aspect, the present invention provides a method for processing a protective shell for the hinge of a civil defense door leaf, which is implemented using the aforementioned processing equipment for the protective shell of the hinge of a civil defense door leaf, and the steps are as follows: S1, the rotating shaft housing body 9 is placed between the fitting cone 808 in the second clamping frame 807 and the first clamping frame 806 for fixation. The rotating disk 1601 rotates to generate centrifugal force, causing the rotating disk 1601 to drive the grinding ring 1608 to move outward and fit against the inner wall of the rotating shaft housing body 9 to grind the rotating shaft housing body 9. S2, after the inner wall of the rotating shaft housing body 9 is polished, the clamping structure 8 moves the rotating shaft housing body 9 to directly above the electroplating solution placement box 5, and the electric telescopic rod 4 moves the electroplating solution placement box 5 upward, so that the chromium inside the electroplating solution placement box 5 comes into contact with the inner wall of the rotating shaft housing body 9, thereby improving the wear resistance of the inner wall of the rotating shaft housing body 9. Then, nickel is plated on the inner wall of the rotating shaft housing body 9 to prevent the rotating shaft housing body 9 from rusting. S3. Finally, the rotating shaft protective shell body 9 is taken out from the electroplating solution placement box 5 and then polished to keep the inside of the rotating shaft protective shell body 9 smooth.

[0027] Working principle of this invention: Refer to the instruction manual appendix Figure 1-6First, when it is necessary to process the pivot housing body 9 of the door leaf pivot connection of the air defense door, the pivot housing body 9 is placed between the first clamping frame 806 and the second clamping frame 807, so that the fitting cone 808 in the first clamping frame 806 and the second clamping frame 807 fits against the top and bottom of the pivot housing body 9. Then, the servo motor 804 drives the second transmission screw 802 to rotate. The threads at both ends of the second transmission screw 802 turn in opposite directions, so that the second transmission screw 802 drives the first clamping frame 806 and the second clamping frame 807 to move relative to each other, so that the first clamping frame 806 and the second clamping frame 807 clamp the pivot housing body 9. Then, the servo motor 804 on the other side of the crossbar 801 drives the second transmission screw 802 to rotate. The second transmission screw 802 drives the lifting frame 10 to rise and fall, so that the lifting frame 10 drives the inner diameter grinding structure 16 to rise and fall on the inner wall of the rotating shaft protective shell body 9 through the transmission shaft 13, and grinds the inner wall of the rotating shaft protective shell body 9. The drive motor 11 drives the drive gear 12 to rotate, and the drive gear 12 drives the drive shaft 13 to rotate through the driven gear 14. The drive shaft 13 drives the rotating disk 1601 to rotate. During the rotation, the rotating disk 1601 generates centrifugal force. Then, the rotating disk 1601 drives the moving block 1607 to slide outward on the inner wall of the limiting groove 1605 and squeeze the return spring 1606. Then, the moving block 1607 drives the grinding ring 1608 to unfold outward and fit against the inner wall of the rotating shaft housing body 9. At the same time, the drive shaft 13 is connected to the pipe through the rotating sealing ring. The water pump pumps the coolant into the interior of the drive shaft 13 through the pipe. The drive shaft 13 is connected to the liquid inlet 1602. The coolant enters the interior of the liquid inlet 1602 and flows out through the liquid outlet 1604 to clean the debris on the inner wall of the rotating shaft housing body 9. After the inner wall of the rotating shaft housing body 9 is cleaned, the motor drives the first transmission screw 7 to rotate. Then, the first transmission screw 7 drives the rotating shaft housing body 9 to move directly above the electroplating solution placement box 5 through the clamping structure 8. The electric telescopic rod 4 pushes the electroplating solution placement box 5 upward, so that the electroplating solution inside the electroplating solution placement box 5 comes into contact with the rotating shaft housing body 9. After the electroplating of the rotating shaft housing body 9 is completed, the inner wall of the rotating shaft housing body 9 is polished to keep the inner wall of the rotating shaft housing body 9 flat, so as to prevent the rotating shaft housing body 9 from rusting and being unable to rotate when it comes into contact with the rotating shaft of the air defense door.

[0028] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
