Description

Technical Field

[0001] This invention relates to a pneumatic disassembly device. Background Technology

[0002] In general industrial disassembly operations, a pry bar is used to lift the object to be disassembled. However, this disassembly method requires the pry bar to be pressed against the reference object on which the object is mounted. This can easily cause the reference object to be damaged by the pressure of the pry bar. If a pry bar is not used for disassembly, manual pulling is required, which is very laborious and inefficient. There are shortcomings that urgently need to be improved.

[0003] Therefore, it is necessary to provide a novel and progressive pneumatic disassembly device to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide a pneumatic disassembly device that can perform disassembly operations with minimal effort and without contacting or damaging other objects.

[0005] To achieve the above objectives, the present invention provides a pneumatic disassembly device, comprising a body and a disassembly assembly. The body includes a chamber, a valve chamber, an air inlet, and a connecting portion. The valve chamber is located between the chamber and the connecting portion. A hammer is slidably mounted in the chamber. The valve chamber has a valve body, and the air inlet communicates with the valve chamber. When a high-pressure gas source is connected through the air inlet, the valve body actuates the hammer to reciprocate. The disassembly assembly includes a limiting member and a connecting member. The connecting member is rotatably mounted on the connecting portion. The limiting member is connected to the connecting portion and stops and limits the connecting member. The connecting member is for connection with a disassembly tool.

[0022] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

[0023] Please refer to Figures 1 to 5 This illustrates a preferred embodiment of the present invention, in which the pneumatic disassembly device comprises a body 1 and a disassembly assembly 3.

[0024] The main body 1 includes a chamber 11, a valve chamber 12, an air inlet 13, and a connecting part 14. The valve chamber 12 is located between the chamber 11 and the connecting part 14. A hammer block 111 is slidably disposed in the chamber 11. The valve chamber 12 is provided with a valve body 121. The air inlet 13 is connected to the valve chamber 12. When a high-pressure gas source is supplied through the air inlet 13, the valve body 121 actuates the hammer block 111 to reciprocate, so as to provide the impact force of reciprocating hammering.

[0025] The disassembly assembly 3 includes a limiting member 31 and a set of connectors 32. The set of connectors 32 is rotatably disposed on the set of connectors 14. The limiting member 31 is connected to the set of connectors 14 and stops and limits the set of connectors 32. The set of connectors 32 is for connection with a disassembly tool 9.

[0026] In this embodiment, the main body 1 includes a first air intake channel 181 and a second air intake channel 182. The first air intake channel 181 is connected to one end of the chamber 11 facing the assembly portion 14, and the second air intake channel 182 is connected to the side of the chamber 11. The valve body 121 is provided with a valve plate 122. The valve plate 122 reciprocates to control the first air intake channel 181 and the second air intake channel 182 to alternately communicate with the air intake portion 13, so that the hammer block 111 can reciprocate to provide the impact force of reciprocating hammering.

[0027] In actual use, the assembly 32 is connected to a disassembly tool 9 (in this embodiment, the disassembly tool 9 is a disassembly sleeve) so that the disassembly tool 9 is connected to an object to be disassembled (not shown). When the hammer 111 moves back and forth to provide a reciprocating hammering impact force, the operator can hold the main body 1 and smoothly pull out the object to be disassembled by the reciprocating hammering impact force of the hammer 111. Therefore, it can not only save effort in disassembly operations, but also avoid contact with other external objects and prevent damage to other external objects, making it more convenient to use.

[0028] Specifically, the assembly part 14 has a first annular wall 141 protruding in a direction away from the chamber 11. The assembly part 32 is rotatably housed in the first annular wall 141. The limiting member 31 is assembled to the first annular wall 141. The assembly part 32 can rotate relative to the first annular wall 141 to prevent the disassembly tool 9 from rotating when the operator rotates the body 1, thus avoiding accidental breakage of the object to be disassembled.

[0029] The first annular wall 141 is provided with a first external thread 142, and the limiting member 31 is provided with an internal thread 314 screwed to the first external thread 142, so as to facilitate the disassembly and assembly of the limiting member 31, and thus the assembly 32 can be quickly replaced when it is damaged.

[0030] Furthermore, the connector 32 includes a head 322 with a larger diameter and a connecting segment 323 with a smaller diameter. The head 322 is rotatably accommodated in the connector portion 14. The limiting member 31 has a through hole 311. The connecting segment 323 passes through the through hole 311 and extends out of the limiting member 31. The limiting member 31 stops the head 322 to prevent the connector 32 from disengaging from the connector portion 14. In this embodiment, the limiting member 31 includes a second annular wall 312 and a baffle 313. The baffle 313 has the through hole 311, and the second annular wall 312 has the internal thread portion 314. The baffle 313 is used to stop the head 322.

[0031] Preferably, the assembly section 323 is further provided with a second external thread 324, which is used for screwing the disassembly tool 9 so that the disassembly tool 9 can be securely fixed to the assembly section 323.

[0032] Additionally, a set of connection holes 15 are provided at one end of the chamber 11 away from the assembly portion 14. These connection holes 15 can be selectively fitted with a cover 16. In this embodiment, a third external thread portion 17 is provided at one end of the body 1 away from the assembly portion 14. The cover 16 is screwed onto the third external thread portion 17. At least one pin 161 is also transversely inserted through the cover 16. Each pin 161 abuts against the body 1 to securely cover the cover 16 with the connection hole 15 and effectively prevent gas leakage from the connection hole 15. In other embodiments, the connection hole 15 can also be used to mount a hammering tool, thus providing a hammering function.

[0033] The air intake 13 extends laterally to the chamber 11 so as to smoothly connect with the valve.

[0034] The above description describes the preferred embodiments of the present invention and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
