Description

Technical Field

[0001] The utility model relates to the field of production auxiliary tools, in particular to a demolition tool and a demolition system. Background Technique

[0002] Riveting is to connect two riveted parts by the deformation of the rivet itself or interference fit. When it is necessary to disassemble the rivet, generally, a screwdriver is first used to pry the rivet loose. After the rivet is loosened to have a gap, a pair of needle-nose pliers is used to clamp it upward, or a pair of strong-jaw pliers is used to cut off the rivet connecting rod and then pull it out, and the rivet can be easily pulled out.

[0003] However, for some special riveting structures, such as Figure 1 and Figure 2 As shown, due to the relatively complex structure of the riveting structure, the above disassembly method cannot be used for disassembly. Therefore, a demolition tool is urgently needed. Content of the Utility Model

[0004] The first object of the utility model is to provide a demolition tool that can take out the rivets in a special riveting structure.

[0005] The second object of the utility model is to provide a demolition system including the above demolition tool.

[0006] To achieve the above first object, a demolition tool provided by the utility model includes a sleeve, an elastic member and a sliding member. A cavity is arranged in the sleeve, an opening is arranged at the first end of the sleeve facing the cavity, a blade is arranged on the outer periphery of the opening of the sleeve, and the blade protrudes from the end face of the first end of the sleeve; the elastic member is arranged in the cavity; the first end of the sliding member is inserted into the opening and arranged on the side of the elastic member close to the opening, the second end of the sliding member is provided with a positioning portion, and in the axial direction of the sleeve, the positioning portion protrudes beyond the blade, and the sliding member can move relative to the blade along the depth direction of the cavity, so that the positioning portion can be recessed into the blade.

[0007] As can be seen from the above solution, by arranging a positioning portion on the sliding member for positioning connection with the hole of the rivet in the riveting structure to be demolished, it is beneficial to ensure the accuracy of the demolition position; by arranging an elastic member, before demolition, the positioning portion protrudes from the blade, which is convenient for positioning connection with the riveting structure to be disassembled. During the demolition process, the sliding member can gradually retract into the cavity, which is convenient for the blade to protrude and embed into the riveting structure to be demolished for demolition.

[0008] A further solution is that the moving distance of the sliding member is greater than or equal to the distance that the blade protrudes from the end face of the first end of the sleeve.

[0009] As can be seen from the above solution, under normal conditions, the positioning portion protrudes from the blade, which is convenient for positioning connection; during the disassembly process, the sliding member moves a certain distance into the cavity, so that the blade protrudes from the sliding member, ensuring that the blade can be embedded into the riveting structure to be demolished.

[0010] A further solution is that a pin shaft is provided at the first end of the sliding member, a sliding hole is axially formed in the middle of the sleeve, and the end of the pin shaft is inserted into the sliding hole and can slide along the extending direction of the sliding hole.

[0011] As can be seen from the above solution, by providing the pin shaft and the sliding hole, during the movement of the sliding member, it can move along the extending direction of the sliding hole, playing a guiding role. On the one hand, it prevents the sliding member from rotating, and on the other hand, it can prevent the sliding member from being accidentally separated from the sleeve.

[0012] A further solution is that the positioning portion is coaxially arranged with the sleeve, and the positioning portion is a cylinder or a groove.

[0013] A further solution is that an installation hole is provided at the first end of the sleeve, one end of the blade is arranged in the installation hole, the cutting edge of the blade protrudes outside the installation hole, the cutting edge extends along the radial direction of the sleeve, and the extending distance of the cutting edge is greater than or equal to the wall thickness of the sleeve.

[0014] As can be seen from the above solution, through the above setting, when the demolition tool rotates for demolition, the cutting edge can form an annular groove on the riveting structure to be demolished, and the sleeve can extend into the annular groove.

[0015] A further solution is that the number of blades is set to be multiple, and the multiple blades are arranged at equal intervals along the circumferential direction of the sleeve.

[0016] A further solution is that a connection portion is provided at the second end of the sleeve, and the connection portion is used to connect with a rotary tool.

[0017] In order to achieve the above second object, a demolition system provided by the present utility model includes an electric drill and the above demolition tool, the electric drill is connected with the demolition tool, and the electric drill can drive the demolition tool to rotate around its own axis.

A positioning hole or a convex column is provided at the end of the first riveting member 64 and / or the second riveting member 65, preferably a positioning hole.

[0027] Embodiment of the demolition tool:

[0028] See Figures 3 to 5 and in combination with Figure 2 In this embodiment, a demolition tool is provided, which includes a sleeve 1, an elastic member 2 and a sliding member 3.

[0029] A cavity is provided inside the sleeve 1. An opening is provided at the first end of the cavity facing the sleeve 1, and a closed end is provided at the second end of the cavity facing the sleeve 1. A blade 4 is provided on the outer periphery of the sleeve 1 at the opening. The number of the blades 4 is preferably set to be multiple. The multiple blades 4 are arranged at equal intervals along the circumferential direction of the sleeve 1, and the cutting edges of the blades 4 protrude from the end face of the first end of the sleeve 1.

[0030] The first end of the sliding member 3 is inserted into the opening. The elastic member 2 is provided inside the cavity and elastically abuts between the first end of the sliding member 3 and the closed end of the cavity, so that the sliding member 3 can move back and forth relative to the blade 4 along the depth direction of the cavity. A positioning portion 31 for cooperating with the positioning hole of the riveting structure 6 to be demolished is provided at the second end of the sliding member 3 to improve the accuracy of the demolition position of the demolition tool.

[0031] Under normal conditions, the positioning portion 31 of the sliding member 3 protrudes from the cavity and outside the blade 4; during demolition, the positioning portion 31 is connected to the rivet. As the sliding member 3 gradually retracts into the cavity, the positioning portion is recessed with the blade, that is, the blade 4 protrudes from the positioning portion 31, so that the blade 4 can directly contact the riveted structure 6 to be demolished, and a circular groove is cut on the riveted structure 6 to be demolished through the rotation of the demolition tool.

[0032] Furthermore, the moving distance of the sliding member 3 is greater than or equal to the distance that the blade 4 protrudes from the first end face of the sleeve 1. In this embodiment, it is preferably that the moving distance of the sliding member 3 is greater than the distance that the blade 4 protrudes from the first end face of the sleeve 1, which is beneficial to increasing the demolition depth and facilitating the complete removal of the rivet of the riveted structure 6 to be demolished.

[0033] The positioning portion 31 is coaxially arranged with the sleeve 1, and the positioning portion 31 is a cylinder or a groove. When the riveted structure 6 to be demolished has a positioning hole, the positioning portion 31 is a cylinder that is connected in cooperation with the positioning hole; when the riveted structure 6 to be demolished has a convex column, the positioning portion 31 is a groove that is connected in cooperation with the convex column. In this embodiment, the former is preferably used.

[0034] In order to prevent the sliding member 3 from rotating during movement, a through hole 32 and a pin shaft 33 are provided at the first end of the sliding member 3. The through hole 32 penetrates both sides of the sliding member 3. The middle part of the pin shaft 33 is arranged in the through hole 32, and both ends of the pin shaft 33 protrude outside the through hole 32. Two sliding holes 11 are provided in the middle of the sleeve 1. The two sliding holes 11 are symmetrically arranged on both sides of the sleeve 1, and the sliding holes 11 extend along the axial direction of the sleeve 1. The end of the pin shaft 33 is inserted into the corresponding sliding hole 11 and can slide along the extending direction of the sliding hole 11. The arrangement of the pin shaft 33, on the one hand, plays a guiding role and prevents the relative rotation of the sliding member 3, and on the other hand, can prevent the accidental separation of the sliding member 3 from the sleeve 1.

[0035] A plurality of mounting holes 12 are provided on the first end of the sleeve 1, and the mounting holes 12 penetrate the wall thickness of the sleeve 1. One end of the blade 4 is fixedly arranged in the mounting hole 12 by glue bonding or interference fit, and the cutting edge 41 of the blade 4 protrudes outside the mounting hole 12. The length direction of the cutting edge 41 extends along the radial direction of the sleeve 1, and the extending distance of the cutting edge 41 is greater than or equal to the wall thickness of the sleeve 1, that is, on the radial projection plane, the projection of the sleeve 1 falls within the projection of the cutting edge 41, so as to ensure that when rotating and demolishing, the blade 4 can form a circular groove on the riveted structure 6 to be demolished, and the sleeve 1 can be embedded in the circular groove. Generally, the diameter of the circular groove is greater than the diameter of the rivet, so that the rivet is located within the circular groove, and as the demolition depth gradually deepens, the rivet can enter the inside of the sleeve 1.

[0036] A connecting portion 13 is provided at the second end of the sleeve 1, and the connecting portion 13 is used to connect with a rotating tool, and the rotating tool can be an electric drill or a manipulator.

[0037] Example of a demolition system:

[0038] Refer to Figure 6 and Figure 7 , this embodiment provides a demolition system, including a drill and the demolition tool of the above embodiment. The chuck 5 on the drill is connected to the demolition tool, preferably detachably connected, and the drill can drive the demolition tool to rotate around its own axis.

[0039] In summary, the utility model sets a positioning portion on the sliding member for positioning connection with the hole in the riveting structure, which is beneficial to ensuring the accuracy of the demolition position; by setting an elastic member, before demolition, the positioning portion protrudes from the blade, facilitating positioning connection with the riveting structure to be disassembled. During the demolition process, the sliding member can gradually retract into the cavity, facilitating the blade to protrude and contact the demolition structure for demolition actions.

[0040] Finally, it should be emphasized that the above are only the preferred embodiments of the utility model and are not used to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications.
