Abstract

The utility model relates to the technical field of disassembly and assembly in the maintenance process of mechanical equipment, in particular to a device capable of damaging a rusted nut. The nut clamping groove and the connecting cylinder are welded into a whole, the connecting cylinder is provided with an internal thread, the push rod is provided with an external thread, the push rod and the connecting cylinder are connected through the threads and can push the steel ball forwards to move, the steel ball pushes the cutter body to move forwards, and the cutter body and the cutter head are connected through the screw. Therefore, the tool bit is driven to move forwards. During use, a nut is sleeved with the nut clamping groove, then the push rod is driven by the electric wrench to move in advance, the push rod pushes the steel ball, the steel ball pushes the cutter body, the cutter body drives the cutter head, and finally the nut is damaged by the cutter head. After the nut is damaged, the push rod is sequentially rotated by an electric wrench, and the spring clamped between the cutter body and the nut clamping groove rebounds to reset the cutter head. The device is simple in structure and convenient to operate, rusted nuts of different sizes can be effectively disassembled, the nut disassembling difficulty is reduced, and the mechanical equipment maintenance efficiency is improved.

Description

TECHNICAL FIELD

[0001] The utility model relates to the device that nut is used in the process of mechanical equipment maintenance is dismantled, specifically a device that can destroy the rusted nut. BACKGROUND

[0002] Any mechanical equipment is assembled and coupled by various parts, and the bolt coupling as the most commonly used fastener can not only obtain great coupling force, but also is convenient and reliable to disassemble, so it is widely used in mechanical engineering. However, because the bolt needs to be in contact with oxygen, water and other substances in the air for a long time, chemical reaction occurs, leading to surface rust, and the nut is difficult to disassemble after a long time, even cannot be disassembled, increasing the difficulty of mechanical equipment maintenance. SUMMARY

[0003] The utility model discloses a device that can destroy the rusted nut, can destroy the rusted nut, the device is simple to operate, practical and convenient, reduces the difficulty of nut disassembly, and improves the mechanical equipment maintenance efficiency.

[0004] The utility model discloses a device that can destroy the rusted nut, can destroy the rusted nut, the device is simple to operate, practical and convenient, reduces the difficulty of nut disassembly, and improves the mechanical equipment maintenance efficiency.

[0005] The structure is composed of a push rod, a connecting barrel, a steel ball, a spring, a cutter body, a cutter head, a screw and a nut clamping groove. One end of the connecting barrel is connected with the nut clamping groove to form an integral body, the connecting barrel is provided with an internal thread, and the push rod is provided with an external thread, so that the push rod can move forward and backward in the connecting barrel. The push rod is provided with a steel ball in front, the steel ball is provided with a cutter body in front, the cutter body is connected with the cutter head through a screw, the electric wrench drives the push rod to move forward to push the steel ball, the steel ball pushes the cutter body, the nut clamping groove is provided with a guide groove, so that the cutter head moves forward without rotating until the nut clamping in the nut clamping groove is destroyed. After the nut is destroyed, the push rod rotates backward, and the spring clamped between the cutter body and the nut clamping groove rebounds to reset the cutter head. ADVANTAGEOUS EFFECTS

[0006] The utility model discloses simple and practical structure, safe and reliable, simple and fast operation, strong destructive force, greatly improve the bolt disassembly efficiency.

[0007] The technical scheme of the utility model is described completely and clearly in combination with the drawings as follows: DRAWINGS

[0008] Figure 1 It is the structure schematic drawing of the utility model;

[0009] Figure 2 It is the schematic drawing of the nut is sleeved;

[0010] Attached Figure Numbers: 1 Push Rod; 2 Connecting Cylinder; 3 Steel Ball; 4 Spring; 5 Blade Body; 6 Blade Head; 7 Screw; 8 Nut Slot; 9 Nut. Detailed Implementation

[0011] like Figure 1 As shown, the connecting cylinder 2 and the nut groove 8 are welded together as one piece. The connecting cylinder 2 has an internal thread, and the push rod 1 has an external thread. The push rod 1 can move back and forth inside the connecting cylinder 2. A spring 4 is installed on the cutter body 5. One end of the cutter body has a shoulder, and one end of the spring is fixed at the shoulder of the cutter body. The cutter body 5 and the cutter head 6 are connected by screws 7. The cutter head can be replaced in time if it is damaged. A square hole is opened in the middle of the nut groove 8. A nut is placed in the square hole, and a cutter head guide groove is provided at the same time, so that the cutter head can move back and forth along the guide groove.

[0012] During operation, first, the nut 9 is fitted into the nut slot 8. Then, an electric wrench is used to rotate the push rod 1. The push rod 1 moves forward, pushing the steel ball 3. The steel ball 3 pushes the cutter body 5 forward. Under the push of the cutter body 5, the cutter head 6 moves forward along the guide groove to break the nut. After the nut is broken, the electric wrench rotates in the opposite direction, the push rod 1 moves backward, the spring 4 rebounds, causing the cutter body 5 to move backward. At the same time, the cutter head 6 moves backward to reset. Finally, the nut breaker is removed, completing the nut breaking process.
