Description

Technical Field

[0001] The utility model relates to the field of disassembly and assembly tools, in particular to a disassembly and assembly tool for a middle barrel. Background Art

[0002] The recoil machine, high-level machine and recoil machine all have the same mechanism, with a middle cylinder inserted in the outer cylinder. Both the outer cylinder and the middle cylinder are very heavy and large in size, and must be disassembled and assembled with the assistance of tools during maintenance. Currently, relevant schemes such as the patent document with publication number CN219562963U discloses a recoil spring disassembly tool. This scheme rotates the screw rod to push the insertion rod, and the insertion rod drives the guide rod in and out of the slide tube. When using this scheme, the screw rod needs to be turned to drive the insertion rod to move, that is, the wrench must always be matched with the screw rod, and the screw rod needs to move axially while rotating. When the operator turns the wrench, it needs to change position with the screw rod. The use scenarios of military equipment usually race against time, and this scheme will obviously affect the efficiency of disassembly and assembly. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a tool for disassembling and assembling the middle cylinder, which can more conveniently drive the screw to move axially, thereby pushing and pulling the middle cylinder from the outer cylinder. This solution is more convenient to operate and can significantly improve the efficiency of assembling and disassembling the middle cylinder.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a tool for disassembling and assembling a middle barrel, comprising a support seat, a screw rod and a support rod;

The front end of the support rod is clamped in the side ear groove of the fixed sleeve, and the position of the side ear groove is locked relative to the position of the support rod by the two sets of positioning nuts.

[0013] Preferably, the front section of the support rod is provided with a fixing structure so as to be connected with the outer cylinder.

[0014] Preferably, the fixing structure is two positioning nuts, and the front section of the support rod is provided with external threads adapted to the two positioning nuts. The front end of the support rod is clamped in the side ear groove of the fixing sleeve, and the position of the side ear groove is locked relative to the position of the support rod by two sets of positioning nuts.

[0015] Preferably, the second screwing head is configured as an external hexagon screwing head, so as to facilitate fixing the screw rod and prevent the screw rod from rotating together when the first screwing head is rotated.

[0016] Advantages of the utility model:

[0017] The above solution can more conveniently drive the screw to move axially, thereby pushing and pulling the middle tube from the outer tube. This solution is more convenient to operate and can significantly improve the efficiency of assembling and disassembling the middle tube. BRIEF DESCRIPTION OF THE DRAWINGS
