[0030] The utility model is further described in conjunction with the following embodiments.

[0031] Example 1.

[0032] like Figure 1-4 As shown, a tool for processing and positioning a movable groove of a grenade support locking nut handle comprises an external positioning block 1. The external positioning block 1 is a rectangular parallelepiped structure. A processing guide groove 2 is opened along the length direction of the external positioning block 1. The processing guide groove 2 runs through the length direction of the positioning block. A plurality of matching clamping ring groove groups 3 are opened on the external positioning block 1 above and below the processing guide groove 2. A locking nut handle 4 is movably installed inside the clamping ring groove group 3.

[0033] The present application is used to process and position the movable groove of the locking nut handle 4 on the 35 grenade support. First, the overall positioning is achieved through the external positioning block 1, and then the processing guide groove 2 is used to guide the processing equipment to move horizontally from the groove to achieve the processing of the movable groove of the handle. The snap-in ring groove group 3 is composed of an arc groove on the external positioning block 1 above the processing guide groove 2 and an arc groove on the external positioning block 1 below the processing guide groove 2. The snap-in ring groove group 3 cooperates with the processing guide groove 2 to movably insert and install the grenade support locking nut handle 4. Several snap-in ring groove groups 3 are opened at the same horizontal height. Cooperating with the processing guide groove 2, the unified processing of several movable grooves of the locking nut handles 4 can be achieved, thereby improving the processing efficiency of the movable groove of the locking nut handle 4.

[0034] The end of the clamping ring groove group 3 away from the open end of the processed guide groove 2 is connected to the interior of the external positioning block 1 and is provided with a screw through hole 5, the end of the screw through hole 5 away from the clamping ring groove group 3 is connected to a nut clamping hole 6, and the end of the locking nut handle 4 close to the screw through hole 5 is provided with a positioning screw hole 7, and a locking bolt 8 is movably installed inside the screw through hole 5 and the nut clamping hole 6, and the locking bolt 8 is spirally locked with the positioning screw hole 7.

[0035] When the locking nut handle 4 is inserted and installed inside the snap ring groove group 3, since the diameter of the screw through hole 5 is smaller than the snap ring groove group 3, one end of the locking nut handle 4 will be snapped at the intersection of the screw through hole 5 and the snap ring groove group 3. At the same time, a positioning screw hole 7 is opened at one end of the locking nut handle 4 close to the screw through hole 5, and a locking bolt 8 is installed inside the nut clamping hole 6. The screw of the locking bolt 8 passes through the screw through hole 5 and spirally cooperates with the positioning screw hole 7, so that the locking nut handle 4 can be snap-locked and locked inside the snap ring groove group 3, thereby realizing the fixation of the locking nut handle 4 and improving the processing accuracy of the movable groove of the grenade support locking nut handle 4.

[0036] The horizontal heights of the plurality of snap ring groove groups 3 are the same, and a chip removal groove 9 is provided between adjacent snap ring groove groups 3 .

[0037] Several clamping ring groove groups 3 have the same height to achieve unified processing. The processing equipment can process a large number of items in one horizontal movement, thereby improving the processing efficiency of the movable groove of the locking nut handle 4. Processing debris can be discharged through the chip removal groove 9.

[0038] A hexagonal positioning screw hole 107 is formed on the nut of the locking bolt 8 .

[0039] The hexagonal positioning screw hole 107 can facilitate the rotation of the locking bolt 8 .

[0040] The screw rod length of the locking bolt 8 is D1, and the length of the screw rod through the hole 5 is D2, and D1 and D2 satisfy D1>D2.

[0041] The screw rod length of the locking bolt 8 is sufficient to allow the locking bolt 8 to pass through the screw rod through hole 5 and to be spirally engaged with the positioning screw hole 7 .

[0042] The locking nut handle 4 is movably fitted with the clamping ring groove set 3 .

[0043] The locking nut handle 4 is snap-fitted into the interior of the snap-fit ​​ring groove set 3 to prevent the locking nut handle 4 from being displaced.

[0044] The utility model clamps the locking nut handle 4 of the grenade support through the clamping ring groove group 3, and at the same time cooperates with the locking bolt 8 to spirally cooperate with the positioning screw hole 7 on the external positioning block 1 to spirally lock one end of the locking nut handle 4 of the grenade support, and then horizontally moves from the processing guide groove 2 to process a plurality of movable grooves of the locking nut handle 4 through processing equipment, thereby improving the processing efficiency and processing accuracy of the movable grooves of the locking nut handle 4 of the grenade support.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
