Description

Technical Field

[0001] The utility model relates to the technical field of fuze drilling, in particular to a fuze test auxiliary drilling device based on a drilling machine. Background Art

[0002] In the process of carrying out fuze testing and other work, ammunition technical support agencies, test sites and other units often need to use drilling machines to drill holes in fuze components and fuze bodies to release the safety of fuze components or to fix the firing pin in fuze strike method tests.

[0003] At present, drilling machine supporting fixtures are usually used to constrain fuze components and fuze bodies for drilling. In view of the many varieties, large quantities and small components of fuze tests, different types of fuze samples will be drilled when conducting different types of fuze tests. The center line of the drilling machine supporting fixture needs to be repeatedly adjusted to be concentric with the drill bit of the drilling machine before drilling. When conducting the same type of fuze test, the amount of fuze samples taken in each batch is too large, and multiple fuze samples of the same type need to be drilled. Each time a fuze sample is drilled, the loosening and restraining process of the drilling machine supporting fixture needs to be repeated, which may lead to low efficiency of the fuze test. Some tiny fuze components do not have fixtures for restraint, and usually need to be manually restrained for drilling, which may cause major safety hazards. Fuzes have high sensitivity characteristics, and the test steps should be simplified as much as possible during the test. The current drilling process of the drilling machine is cumbersome and there are certain safety hazards. Utility Model Content

[0004] In order to solve the technical problem that when conducting different types of fuze tests, the center line of the drilling machine's supporting fixture must be repeatedly adjusted to be concentric with the drill bit of the drilling machine before drilling can be performed, the utility model provides a fuze test auxiliary drilling device based on a drilling machine.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A fuze test auxiliary drilling device based on a drilling machine includes a base, a sample constraint seat and a drill template cover plate; the sample constraint seat is detachably connected to the drill template cover plate and the base, and is provided with a constraint hole, the drill template cover plate is provided with a drill hole, the drill hole is connected to the constraint hole, and the base is fixed with a clamping block.

[0007] Furthermore, an upper plug rod is fixedly provided on the drilling template cover plate, an upper plug hole is opened on the sample restraining seat, and the upper plug rod is plugged into the upper plug hole.

[0008] Furthermore, a lower plug rod is fixedly provided on the sample restraining seat, a lower plug hole is provided on the base, and the lower plug rod is plugged into the lower plug hole.

[0009] Furthermore, the sample restraint seat is a rotating body restraint seat, and the restraint hole is cylindrical.

[0010] Furthermore, the sample constraint seat is a component constraint seat, and a pressure block is fixedly arranged at the bottom end of the drill template cover plate, the pressure block is provided with a through hole and two upper grooves, and two upper protrusions are fixedly arranged, the constraint hole is provided with two lower grooves and a through hole, and two lower protrusions are fixedly arranged, the through hole is connected to the drill hole, the upper protrusion is slidably connected to the lower groove, the lower protrusion is slidably connected to the upper groove, and the pressure block is slidably connected to the constraint hole.

[0011] Furthermore, the sample restraint seat is a fuze body restraint seat, the restraint hole includes an upper hole section and a lower hole section, the upper hole section and the lower hole section are both cylindrical, the width of the upper hole section is greater than the width of the lower hole section, and the upper hole section connects the borehole and the lower hole section.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model adopts a base, a sample restraint seat, a drilling template cover plate and a clamping block, so that when testing different types of fuzes, it is only necessary to adjust the center of the base once to be concentric with the sample restraint seat, the drilling template cover plate and the drill bit of the drilling machine. When drilling holes in different types of fuze samples, it is only necessary to replace the sample restraint seat and the drilling template cover plate to realize the drilling function of the drilling machine, which solves the problem that the center line of the drilling machine supporting fixture must be repeatedly adjusted to be concentric with the drilling machine drill bit before drilling when conducting different types of fuze tests. It also avoids the need to repeat the loosening and restraining process of the drilling machine supporting fixture each time the fuze is drilled when conducting the same type of fuze test, thereby improving the efficiency of the fuze test;

[0014] 2. The utility model adopts a component restraint seat, a pressure block and a restraint hole to restrain the tiny components of the fuze, avoiding the need to manually restrain the tiny components of the fuze for punching holes, thereby reducing safety hazards; the fuze test auxiliary punching device based on a drilling machine of the utility model effectively simplifies the test process and steps, and greatly increases the test efficiency.

The clamp block 4 is in the shape of a rectangular parallelepiped. The base 3, the sample constraint seat 2 and the drilling template cover plate 1 are all in the shape of a cylinder. When the fuze sample is to be drilled, the sample constraint seat 2 is first connected to the base 3, and then the fuze sample is placed in the constraint hole 6. Then the drilling template cover plate 1 is connected to the sample constraint seat 2, and then the drilling machine drill bit is started. The drilling machine drill bit will pass through the borehole 5 and enter the constraint hole 6 to drill the fuze sample. When drilling holes for different types of fuze samples, it is only necessary to perform the drilling according to the above steps, and replace the sample restraint seat 2 and the drill template cover plate 1 with the sample restraint seat 2 and the drill template cover plate 1 corresponding to the type of the fuze sample; when drilling holes for multiple fuze samples of the same type, it is only necessary to remove the drill template cover plate 1 from the sample restraint seat 2, then take out the punched fuze sample, put the new fuze sample into the restraint hole 6, and then connect the drill template cover plate 1 to the sample restraint seat 2 to perform the drilling.

[0030] like Figure 3 As shown, an upper plug rod 7 is fixedly provided on the drilling template cover plate 1 , an upper plug hole 8 is opened on the sample restraining seat 2 , and the upper plug rod 7 is plugged into the upper plug hole 8 .

[0031] When the jig cover plate 1 and the sample restraining seat 2 are to be connected, the jig cover plate 1 is moved to allow the upper insertion rod 7 to be inserted into the upper insertion hole 8. The number of the upper insertion rod 7 and the number of the upper insertion hole 8 can be four.

When the tiny parts of the fuze are to be constrained, the tiny parts of the fuze are first placed into the constraint hole 6 of the parts constraint seat 12. The two lower protrusions 14 and the two lower grooves 13 will limit the tiny parts of the fuze to prevent the tiny parts of the fuze from rotating. Then, the drilling template cover plate 1 is placed on the parts constraint seat 12, and the upper insertion rod 7 is inserted into the upper insertion hole 8. The upper protrusion 21 will slide into the lower groove 13, and the lower protrusion 14 will slide into the upper groove. 22, the pressing block 19 will slide into the constraint hole 6 and press the tiny parts of the fuze, so as to facilitate the drilling of the tiny parts of the fuze and avoid the misalignment of the tiny parts of the fuze, resulting in eccentric drilling and safety hazards; when drilling, the drill bit of the drilling machine is started, the drill bit of the drilling machine will pass through the drill hole 5 and the through hole 20 and enter the constraint hole 6 to drill the tiny parts of the fuze. After the drilling of the tiny parts of the fuze is completed, the drill bit of the drilling machine will pass through the tiny parts of the fuze and enter the through hole 11. Both the constraint hole 6 and the through hole 11 can be blind holes.
