[0029] When disassembling and assembling the knife claw, it is necessary to overcome the inner cooling sealing rod and the spring to twist the screw. Since the sealing requirements of the knife claw are very high and the spring force is large, the existing disassembly and installation method is to use an extended hexagonal rod to overcome the spring force, and multiple people work together to twist out the knife claw screw before the knife claw can be removed. However, when disassembling and assembling the knife claw screw, there is no guide and the force is uneven, which makes installation and disassembly very difficult, and it is easy to damage the inner cooling rod sealing ring. The entire disassembly and assembly process takes a long time and the success rate is low, making it difficult to advance the maintenance work.

[0030] Based on this, the present application provides a disassembly and assembly tool for the spindle claw, which can effectively solve the problems of no spring guidance and uneven force, and facilitate the disassembly and installation of the claw screws, thereby facilitating the disassembly and installation of the claw. It is very simple and convenient to use, and will not cause damage to the internal cooling rod sealing ring. It can reduce the disassembly and assembly time, increase the success rate, and help the smooth progress of maintenance work.

[0031] See also Figures 1 to 3 , the present application provides a disassembly and assembly tool for a spindle jaw, comprising: a base plate 1, a fastening nut 2, an extension screw 4, a spring 9, a sleeve connecting rod 3, a spring connecting assembly, a T-type spacer 5 and a sleeve 8;

[0032] The T-shaped spacer 5 is installed in the middle position of the base plate 1, one end of the sleeve connecting rod 3 is arranged on the base plate 1 through the T-shaped spacer 5, and the other end of the sleeve connecting rod 3 is installed with the sleeve 8 piece. The spring connecting assembly is movably installed on the sleeve connecting rod 3, one end of the spring 9 is connected to the T-shaped spacer 5, and the other end of the spring 9 is connected to the spring connecting assembly. The extension screw 4 is installed on both sides of the base plate 1, and the fastening nut 2 is connected to the extension screw 4 and is arranged at the upper end of the base plate 1. The spring connecting assembly is used to adjust the elastic force of the spring 9. The base plate 1 cooperates with the fastening nut 2 and the extension screw 4 to drive the T-shaped spacer 5 to move downward. The T-shaped spacer 5 compresses the spring 9 so that the spring 9 pushes the sleeve connecting rod 3 to move downward. When the spring 9 has a reaction force feedback, the sleeve 8 rotating rod is rotated and cooperated with the sleeve 8 piece to realize the disassembly and installation of the knife claw.

[0033] In the embodiment of the present application, an opening is provided at the middle position of the base plate 1, a T-shaped spacer 5 is placed at the lower end of the opening, and the sleeve connecting rod 3 penetrates the T-shaped spacer 5. Specifically, a head cover 31 and a connecting rod 32 are provided at the upper end of the sleeve connecting rod 3. The head cover 31 and the connecting rod 32 are integrally formed, which means that the connection between the head cover 31 and the connecting rod 32 is a non-detachable connection, such as welding or casting, which is not specifically limited here. The cross-sectional area of ​​the connecting rod 32 is smaller than the cross-sectional area of ​​the head cover 31. The connecting rod 32 penetrates the T-shaped spacer 5. The head cover 31 is clamped on the top of the base plate 1. One end of the spring 9 is connected to the bottom of the T-shaped spacer 5, and the other end of the spring 9 is connected to the spring connecting assembly. The spring 9 cooperates with the spring connecting assembly and the connecting rod 32 to fix the T-shaped spacer 5 at the lower end of the base plate 1, thereby preventing the T-shaped spacer 5 from falling down.

[0034] The two ends of the bottom plate 1 are connected to the lengthened screw 4. Specifically, rectangular through holes are provided on both sides of the opening. The upper end of the lengthened screw 4 is provided with a first external thread 41, and the lower end of the lengthened screw 4 is provided with a second external thread 42. An empty area is provided between the first external thread 41 and the second external thread 42. The spring connection assembly includes a spacer 7 and a hexagon socket nut 6. The spacer 7 is sleeved in the sleeve connecting rod 3. The other end of the spring 9 is connected to the spacer 7. The hexagon socket nut 6 is installed in the spacer 7. The spacer 7 can be fixed in the sleeve connecting rod 3 by the hexagon socket nut 6. Since the spring 9 is arranged between the T-type spacer 5 and the spacer 7, when the position of the spacer 7 on the sleeve connecting rod 3 is adjusted, the elastic force of the spring 9 can be adjusted. When the distance between the spacer 7 and the T-type spacer 5 is shortened, the spring 9 is in a compressed state. At this time, under the action of the spring 9, the T-type spacer 5 is in a fixed state and cannot be moved.

[0035] The rectangular through hole on the base plate 1 is used to connect with the first external thread 41 on the extension screw 4. Specifically, after the base plate 1 is placed on the extension screw 4 through the rectangular through hole, the fastening nut 2 is installed on the first external thread 41 and is set on the upper end of the base plate 1. Under the action of the fastening nut 2, the base plate 1 can be pressed downward so that the base plate 1 has a downward pressing force. When the spring 9 is in a compressed state, the T-shaped spacer 5, the spring 9 and the spring connecting assembly can push the base plate 1 upward, so that the base plate 1 has an upward pushing force, thereby fixing the base plate 1 on the extension screw 4.

[0036] Among them, it should be noted that the matching connection mode between the connecting rod 32 and the T-shaped spacer 5 is a clearance fit, that is, the connecting rod 32 part on the sleeve connecting rod 3 can be rotated on the T-shaped spacer 5, and the head cover 31 of the T-shaped spacer 5 is provided with a hexagonal countersunk hole for facilitating connection with an external rotating tool. By rotating the head cover 31 through the rotating tool, the sleeve connecting rod 3 can be rotated.

[0037] In practical applications, first adjust the position of the spring connection assembly on the sleeve connecting rod 3, that is, shorten the distance between the spacer 7 and the T-type spacer 5, so that the spring 9 is in a compressed state. Specifically, first turn the hexagonal nut 6 to separate the spacer 7 from the connecting rod 32, and then move the spacer 7 upward. After moving to a suitable position, the spring 9 is in a compressed state, and then the hexagonal nut 6 is screwed to fasten the spacer 7 to the connecting rod 32. The compressed spring 9 has a certain overcoming force. After the installation is completed, the second external thread 42 on the extension screw 4 is connected to the screw hole on the end face of the main shaft. After the two extension screws 4 are fixed, the two rectangular through holes on the bottom plate 1 are respectively inserted into the corresponding extension screws 4, and the fastening nut 2 is placed above the bottom plate 1, and then the sleeve 8 on the sleeve connecting rod 3 is inserted into the orifice of the main shaft. After the insertion is completed, turn the fastening nut 2 on the extension screw 4. Under the action of turning the fastening nut 2, the base plate 1 can be moved downward. During the downward movement of the base plate 1, the T-type spacer 5 will be driven downward, thereby further compressing the spring 9. The force of the spring 9 will act on the spring connecting assembly. Since the spring connecting assembly is fixedly connected to the sleeve connecting rod 3, the force will act on the sleeve connecting rod 3, thereby driving the sleeve connecting rod 3 to move downward. When the spring 9 is adjusted to have reaction force feedback, stop turning the fastening nut 2. At this time, it means that the spring force inside the spindle has been overcome. Finally, the ratchet wrench is connected to the hexagonal countersunk hole on the head cover 31, and the sleeve connecting rod 3 is rotated to realize the removal or installation of the knife claw.

[0038] It can be further known that by using the disassembly and assembly tools, the problems of no spring guidance and uneven force can be effectively solved, and the knife claw screws can be easily disassembled and installed, thereby facilitating the disassembly and installation of the knife claws. It is very simple and convenient to use, and will not cause damage to the inner cooling rod sealing ring. It can reduce the disassembly and assembly time, increase the success rate, and help the smooth progress of maintenance work.

Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application.
