[0039] The utility model is further described in conjunction with the following embodiments.

[0040] Example 1.

[0041] like Figure 1-6 As shown, a howitzer sighting guide lock sliding limit hole processing clamping tool includes a positioning chassis 1, a drilling seat 2 is fixedly installed on the positioning chassis 1, two end bolts of the drilling seat 2 are installed with two bent positioning plates 3, the bent positioning plate 3 is formed by a first positioning plate 31 and a second positioning plate 32 and installed vertically, the two first positioning plates 31 are installed with the two end bolts of the drilling seat 2, the second positioning plate 32 is provided with a positioning slide 4, and an elastic clamping mechanism 5 is installed inside the positioning slide 4 for sliding.

[0042] The present application is used for processing the sliding limit hole of the sighting guide lock of the 35 howitzer. First, the overall tooling is positioned by positioning the chassis 1, and then the sighting guide lock rotating shaft 8 is limited and fixed by the drilling seat 10 and then the sliding limit hole is processed. The elastic clamping mechanism 5 is slidably installed on one side of the drilling seat 10 by bending the positioning plate 3, and the sighting guide lock rotating shaft 8 is axially limited by the elastic clamping mechanism 5 at one end.

[0043] A movable groove 6 is provided on the drilling seat 2 along the length direction, and a plurality of workpiece positioning through holes 7 are also provided on the drilling seat 2. An observation guide lock rotating shaft 8 is movably installed inside the workpiece positioning through hole 7. A drill sleeve 9 is installed on the top of the drilling seat 2, and a drill hole 10 is provided inside the drill sleeve 9. The drill hole 10 is connected to the workpiece positioning through hole 7.

[0044] The drilling seat 10 2 facilitates the installation of the sighting guide lock rotating shaft 8 through the movable groove 6, and the sighting guide lock rotating shaft 8 is inserted into the inside of the workpiece positioning hole to achieve the limitation of the workpiece, and the sliding limiting hole of the sighting guide lock rotating shaft 8 is processed at the top of the sighting guide lock rotating shaft 8 by extending the drill bit into the drilling hole 10.

[0045] The elastic clamping mechanism 5 includes a pressure cover 51, both ends of which are slidably installed inside the positioning slide 4 through a sliding bolt assembly 52. ​​The pressure cover 51 slides and fits on the side of the drilling hole 10 seat 2 close to the movable groove 6. A plurality of limiting through holes 53 are opened inside the pressure cover 51. A rear top block 54 is spirally installed at one end of the limiting through hole 53 away from the drilling hole 10 seat 2.

The front top block 56 is movably installed inside the limiting through hole 53, and the front top block 56 is movably fitted with the sighting guide lock rotating shaft 8.

[0046] The elastic clamping mechanism 5 realizes the lifting and lowering of the pressure cover 51 through the sliding installation of the pressure cover 51 and the positioning slide 4. When the pressure cover 51 drops to the bottom, the workpiece positioning through hole 7 is completely exposed, which is convenient for the installation of the aiming guide lock rotating shaft 8. When the aiming guide lock rotating shaft 8 is installed in the workpiece positioning through hole 7, the pressure cover 51 is slid and lifted.

[0049] A positioning strip 13 is installed inside the movable groove 6, and a fixing bolt 14 is spirally installed on the drilling seat 10 between the workpiece positioning through holes 7. The fixing bolt 14 is bolted to the positioning strip 13, and the sighting guide lock rotating shaft 8 is movably connected to the positioning strip 13.

[0050] The interior of the movable groove 6 is engaged with the sighting guide lock rotating shaft 8 through a positioning strip 13 to achieve axial limitation of the other end of the sighting guide lock rotating shaft 8. The positioning strip 13 is fixed to the drilling seat 10 2 through a fixing bolt 14, fixedly installed in the movable groove 6, and engaged with the sighting guide lock rotating shaft 8.

[0051] The sliding bolt assembly 52 includes a sliding screw 521 , which slides through the positioning slide 4 . Two limiting nuts 522 are spirally mounted on the sliding screw 521 on both sides of the positioning slide 4 . The two limiting nuts 522 are movably fitted with the second positioning plate 32 .

[0052] The sliding bolt assembly 52 slides inside the positioning slideway 4 through the sliding screw 521, and at the same time, the lateral limitation is achieved on both sides of the positioning slideway 4 through the limiting nut 522, ensuring that the sliding screw 521 and the pressure cover 51 slide vertically.

[0053] The utility model limits the howitzer sighting guide lock and clamps one end thereof through the workpiece positioning through hole 7 and the positioning strip 13, and then realizes the axial limitation of the front top block 56 and the other end of the sighting guide lock rotating shaft 8 through the lifting and lowering of the positioning slide 4 by the elastic clamping mechanism 5, and then the drill bit processes the sliding limiting hole of the sighting guide lock rotating shaft 8 through the drill hole 10 on the drill sleeve 9, thereby ensuring the stable fixation of the howitzer sighting guide lock and improving the accuracy of the sliding limiting hole of the howitzer sighting guide lock.
