[0035] The utility model is further described in conjunction with the following embodiments.

[0036] Example 1.

[0037] like Figure 1-2 As shown, a rotary tooling for processing a conversion positioning hole of a machine gun locking base comprises a fixed base 1, on which two positioning vertical plates 13 are installed, a positioning outer tube body 2 is installed between the two positioning vertical plates 13, telescopic sleeves 3 are rotatably installed at both ends of the inner part of the positioning outer tube body 2 through two deep groove ball bearings, one end of the telescopic sleeve 3 is bolted to a rear positioning sleeve 4, the other end of the telescopic sleeve 3 is bolted to a front positioning plate 5, two clamping positioning plates 6 are fixedly installed on the side of the front positioning plate 5 away from the telescopic sleeve 3, and a rotating telescopic mechanism 7 is installed inside the telescopic sleeve 3 and the rear positioning sleeve 4.

[0038] The present application is used to rotationally clamp the machine gun locking base 83, which is convenient for processing the conversion positioning holes of the thousands of locking bases. First, the overall equipment is supported and fixed by the fixed base 1, and then the telescopic sleeve 3 is rotationally fixed by the positioning outer tube body 2. The rear positioning sleeve 4 and the front positioning plate 5 are bolted on both ends of the telescopic sleeve 3, and the rotary output transmission is realized by rotating the telescopic mechanism 7.

[0039] The rotating telescopic mechanism 7 includes a telescopic head 71, which is movably installed inside the telescopic sleeve 3. An internal threaded hole 72 is provided at one end of the telescopic head 71 close to the rear positioning sleeve 4. A threaded rotating shaft 73 is spirally installed inside the internal threaded hole 72. An end of the threaded rotating shaft 73 away from the internal threaded hole 72 rotates through the rear positioning sleeve 4 and is fixedly installed with a handwheel 74. The outside of the threaded rotating shaft 73 is rotatably installed inside the rear positioning sleeve 4 through an angular contact ball bearing 75 and a thrust ball bearing 76 and the rear positioning sleeve 4. The end of the telescopic head 71 away from the rear positioning sleeve 4 passes through the front positioning plate 5 and is movably installed with a rotating clamping mechanism 8.

[0040] The rotating telescopic mechanism 7 drives the threaded rotating shaft 73 to rotate by rotating the hand wheel 74. At the same time, the threaded rotating shaft 73 realizes axial positioning and radial positioning through the angular contact ball bearing 75 and the thrust ball bearing 76. It will only rotate inside the telescopic sleeve 3 without causing displacement, driving the telescopic head 71 that is spirally matched with it to realize telescopic activities inside the telescopic sleeve 3. At the same time, the telescopic head 71 drives the rotating clamping mechanism 8 to clamp and release the machine gun locking seat.

[0041] The rotating clamping mechanism 8 includes a bending rotating clamping claw 81 which is hingedly mounted on two clamping positioning plates 6 and cooperates with each other. The end of the bending rotating clamping claw 81 close to the telescopic sleeve 3 is hingedly mounted with a connecting plate 82, and the connecting plate 82 is also hinged to the telescopic head 71. The ends of the two bending rotating clamping claws 81 away from the telescopic sleeve 3 are movably clamped with a machine gun locking base 83.

[0042] The rotating clamping mechanism 8 drives the two connecting plates 82 hinged thereto to move through the telescopic head 71, and at the same time, the connecting plate 82 drives the bending rotating clamping claw 81 hinged thereto to realize clamping rotation. The middle part of the bending rotating clamping claw 81 is hinged on the two clamping positioning plates 6. When one end of the bending rotating clamping claw 81 close to the connecting plate 82 receives a pulling force, the other end will buckle back to clamp the machine gun locking base 83.

[0043] The tops of the two positioning vertical plates 13 are each provided with a locking positioning portion 9, on which a rotation locking assembly 10 is movably mounted, and a positioning top block 11 is fixedly mounted on the clamping positioning plate 6 close to the locking positioning portion 9, and the rotation locking assembly 10 and the positioning top block 11 are plug-fitted.

[0044] The front positioning plate 5 and the positioning vertical plate 13 are fixed to each other through the plug-in cooperation of the rotation locking assembly 10 and the positioning top block 11, thereby realizing the rotation locking of the machine gun locking base 83.

[0045] The rotary locking assembly 10 includes a locking shaft 101, which movably passes through the two locking positioning parts 9. A hexagonal rotating cap 102 is fixedly installed at one end of the locking shaft 101 close to the rear positioning sleeve 4, and a locking head 103 is movably provided at one end of the locking shaft 101 close to the front positioning plate 5. The locking head 103 is movably inserted into the interior of the positioning top block 11.

[0046] The rotary locking assembly 10 is locked at two locking positioning parts 9 through the locking shaft 101, and the locking shaft 101 is turned through the hexagonal rotating cap 102. At the same time, the locking shaft 101 is inserted into the interior of the positioning top block 11 through the locking head 103 to achieve rotational locking, thereby facilitating the processing of the conversion positioning hole of the machine gun locking base 83.

[0047] Protective side plates 12 are installed on both sides of the two clamping and positioning plates 6 .

[0048] The protective side plate 12 can protect the connection portion between the telescopic head 71 and the bending and rotating clamping claw 81 .

[0049] A limit screw 104 is screwed onto the locking shaft 101 .

[0050] The installation of the limit screw 104 can ensure that when the locking head 103 is fully inserted into the interior of the positioning top block 11, it is engaged with one of the positioning vertical plates 13 to prevent the locking shaft 101 from falling off. At the same time, when the locking head 103 is fully pulled out from the interior of the positioning top block 11, it is also engaged with the positioning vertical plate 13 to prevent the locking head 103 from being stuck in the interior of the positioning top block 11.

[0051] The utility model realizes rotation and extension through the rotation and extension mechanism 7, drives the rotation clamping mechanism 8 to clamp the machine gun locking base 83, and at the same time, the rotation of the machine gun locking base 83 can be realized through the rotation installation test of the deep groove ball bearing and the telescopic sleeve 3, and then the rotation locking is realized through the rotation locking component 10 and the positioning top block 11, so that the clamping and rotation of the gun locking base are realized, and the processing efficiency of the conversion positioning hole is improved.

[0052] 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.
