Description

Technical Field

[0001] The utility model relates to the technical field of fin-stabilized armor-piercing discarding sabot projectile technology, in particular to a processing auxiliary device for a fin-stabilized armor-piercing discarding sabot projectile support. Background Art

[0002] The sabot of an armor-piercing discarding sabot projectile is generally made of lightweight materials such as aluminum alloy and adopts a multi-petal structure so that it can be quickly separated after firing. The interior of the sabot is designed with a structure that is closely integrated with the core, such as a belt or a fastening ring, to ensure that the sabot can stably support the core during firing. It mainly plays the role of supporting the core to prevent the core from deformation or damage in the barrel. It is an important component of the armor-piercing projectile. Its design, material and processing have an important influence on the performance of the armor-piercing projectile. When processing it, a processing auxiliary device for the sabot of a tail-stabilized armor-piercing discarding sabot projectile is required for use in conjunction with it.

[0003] Existing armor-piercing discarding sabot cartridges often have a multi-petal structure, so during processing, it is easy to produce problems with the inner and outer roundness distortion, which will lead to the problem of low coaxiality of the combined assembly after the subsequent processing is completed. In addition, during processing, different petals need to be clamped before processing. Such multiple operations are likely to cause large errors in the subsequent process, and corresponding processing measures are required. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a processing auxiliary device for a tail-stabilized armor-piercing projectile sabot, including:

[0021] A cylinder 1 is provided with a rotating shaft 2 in the cylinder 1, the rotating shaft 2 is rotatably connected to the side wall of the cylinder 1 through a bearing, a No. 1 bevel gear 3 is fixedly connected to the circumference of the rotating shaft 2, and a plurality of clamping and splicing mechanisms are provided. The clamping and splicing mechanisms include a splicing assembly and a clamping assembly. The splicing assembly includes a No. 1 threaded rod 4 provided in the cylinder 1, the No. 1 threaded rod 4 is rotatably connected to the inner wall of the cylinder 1 through a bearing, a No. 2 bevel gear 5 is fixedly connected to the bottom end of the No. 1 threaded rod 4, and the No. 2 bevel gear 5 is meshed with the No. 1 bevel gear 3. A nut 6 is threadedly connected to the No. 1 threaded rod 4, and a fixing plate 7 is fixedly connected to the side wall of the nut 6. A plurality of guide rods 12 are equidistantly fixedly connected to the circumferential side wall of the cylinder 1, and guide plates 13 are slidably sleeved on the plurality of guide rods 12. The plurality of guide plates 13 are respectively fixedly connected to the side walls of the plurality of nuts 6 to ensure that the plurality of splicing assemblies can operate normally, and a rotating handle is fixedly connected to the end of the rotating shaft 2 away from the No. 1 bevel gear 3 to facilitate operation by the staff;

[0022] The clamping assembly includes a No. 1 arc-shaped clamping plate 8 fixedly connected to the side wall of the fixed plate 7 and a mounting plate 9. A threaded through hole is provided on the upper surface of the mounting plate 9. A No. 2 threaded rod 10 is threadedly connected to the inner thread of the threaded through hole. The bottom end of the No. 2 threaded rod 10 is rotatably connected to the No. 2 arc-shaped clamping plate 11 through a bearing. A plurality of No. 2 threaded rods 10 are fixedly connected with knobs at one end away from the No. 2 arc-shaped clamping plate 11 for the convenience of operation by the staff. The side walls of the plurality of No. 2 arc-shaped clamping plates 11 close to the fixed plate 7 are all in contact with the side wall of the fixed plate 7, so that the plurality of No. 2 arc-shaped clamping plates 11 have sufficient stability when moving.

[0023] The detailed working process of the utility model is as follows:

[0024] When in use, first complete the clamping and fixing of multiple support parts. Here, a three-petal support is applicable. Multiple support components are fixed by multiple clamping assemblies. Here, a clamping assembly is taken as an example. According to the splicing state of the support, a single support component is placed between the first arc clamping plate 8 and the second arc clamping plate 11. Then, the second threaded rod 10 is rotated by the knob. The rotation of the second threaded rod 10 will engage with the threaded through hole, thereby causing the second threaded rod 10 to move relative to the mounting plate 9, thereby driving the second arc clamping plate 11 to move. When clamping and fixing is required, the second arc clamping plate 11 will gradually approach the first arc clamping plate 8, thereby achieving the clamping and fixing of the support components between the two.

[0025] After completing the fixation of the above-mentioned multiple support parts, the rotating shaft 2 is rotated by turning the handle, thereby driving the No. 1 bevel gear 3 to rotate, and then driving the multiple No. 2 bevel gears 5 to rotate through meshing transmission. Here, taking a spliced ​​component as an example, the rotation of the No. 2 bevel gear 5 drives the No. 1 threaded rod 4 to rotate. When the No. 1 threaded rod 4 rotates, the nut 6 will be threadedly meshed with the No. 1 threaded rod 4 under the restriction of the guide plate 13 and the guide rod 12, and then move along the No. 1 threaded rod 4, thereby driving the clamping component to move through the fixing plate 7, and realizing the movement of the support component. The multiple spliced ​​components run synchronously, and then the multiple support components move synchronously close to each other, thereby realizing the splicing of the entire support. Subsequent processing in this state can increase the processing accuracy and processing quality, thereby improving the quality of subsequent support products.

[0026] 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 it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
