Among them, the medicine pressing component 8 includes a bracket 81 and a medicine pressing cylinder 82. The bracket 81 is a door-type frame. The bracket 81 is arranged on the side of the annular charge column 00. The medicine pressing cylinder 82 is arranged on the top of the bracket 81. The lower end of the piston rod of the medicine pressing cylinder 82 is provided with a pressing plate 83 for pressing and fixing the annular charge column 00. The pressing plate 83 is arranged above the annular charge column 00. A medicine pressing assembly is used to press and fix one side of the annular medicine column, and a cutter driving component is used on the other side to drive the cutter downward to realize the cutting operation of the annular medicine column.

[0020] In a specific embodiment of the present invention, Figure 1 , 4 -6, the equidistant feeding assembly 7 includes a gear-shifting cylinder 71, a rack 72 and a gear-shifting mechanism 73.

A cushion block 734 is provided between the lever II 732 and the lever I 731 and between the mating surfaces of the lever II 732 and the support rod 733. The support rod 733 and the lever I 731 are arranged on the same side of the lever II 732. Figure 6 The double-direction arrow in the middle indicates the movement direction of lever I and lever II, and the unidirectional arrow below indicates the movement direction of the slide. The connecting rod working principle is used to make the pusher claw drive the rack to make linear motion, thereby pushing the slide to move. The moving distance (4mm, 10mm) is determined by the rack spacing.

[0021] During specific operation, the upper end of the lever I731 is rotatably connected to the movable end of the push-pull cylinder 10, and the push-pull cylinder 10 is connected to the piston rod of the gear-shifting cylinder 71 through the connecting rod 11. Among them, the lower end of the piston rod of the push-pull cylinder 10 is hinged with a connecting rod with a long strip slide groove, and the upper end of the lever I731 is slidably matched with the long strip slide groove of the connecting rod through a connecting pin, and the push-pull cylinder 10 can drive the connecting rod to rise and fall, and drive the lever I731 to swing up and down.

[0022] During assembly, height-adjustable legs are installed at the bottom of the charge sample making machine, and the levelness of the bottom plate can be adjusted by the legs. Before operation, the charge sample making machine is adjusted to a level by adjusting the legs.

[0023] The present invention also provides a composite solid propellant annular grain sample preparation method, which adopts the composite solid propellant annular grain sample preparation device to prepare samples. In this embodiment, the propellant annular grain with a height greater than 150 mm and less than 270 mm is cut into 150 mm fixed heights, and then the 150 mm high annular grain is cut into two semi-cylindrical annular grains, and finally the semi-cylindrical annular grains are cut into mechanical or burning rate tablets of a certain thickness. Specifically, the following steps are included: Step 1, fix the slide 1 and the bottom plate 2, so that the distance between the bracket of the medicine pressing assembly 8 and the cutter 6 is consistent with the fixed height size of the annular medicine column 00. In this embodiment, it can be adjusted according to a distance of 150-160mm. First, the operator marks the position of the cutter and the position of the knife holder on the slide of the sample making machine, and marks the dividing line on the annular medicine column.

[0024] Step 2, personnel enter the isolation room, place the annular charge 00 with a height greater than 150 mm and less than 270 mm horizontally on the slide 1, position one end of the annular charge 00 close to the bracket 81 of the medicine pressing assembly 8, and fix the other end of the annular charge 00 close to the right-angle fixing piece 14 to fix the front section of the annular charge, and the right-angle fixing piece 14 is fixed to the slide 1 by screws; Step 3: Personnel evacuate the isolation room, and personnel in the control room observe through video surveillance, control the cutter drive component on the central console, drive the cutter 6 to cut the end of the annular charge column 00, and complete the height setting of the annular charge column 150mm. For cutters or annular charges of different sizes, you can choose to cut once or multiple times according to the actual situation. Figure 8 Shown is a schematic diagram of four rotation positioning and cutting to remove excess height of the annular grain column.

[0025] Step 4, after the cutter is reset, the personnel enter the isolation room, put the annular charge column upright on the slide, adjust the position, use the medicine pressing assembly 8 to fix one side of the annular charge column 00, start the cutter driving component 5 to drive the cutter 6 to split the annular charge column 00. For annular charge columns with larger diameters, a single-knife one-time splitting process is used, which has higher requirements on the tool and driving force. Therefore, the method of first decomposing the cylinder and then slicing is adopted. The decomposition of the annular charge column is to decompose the annular charge column into two semi-cylindrical square billets by two clamping and two cutting methods.

[0026] like Fig. 9 , 10 As shown, a 150mm high annular column 00 is fixed on the slide 1, and the sample cylinder 51 pushes the knife holder 52 to cut one side of the annular column 00. Then the annular column is positioned and split for the second time to achieve the purpose of cutting the annular column into two pieces. During the process, after the first split, the personnel enter the isolation room, rotate the annular column 180 degrees, adjust the position and fix it; the personnel leave and cut the column again by remote operation in the living room.

[0027] Step 5, fix the divided semicircular medicine column in batches, start the cutter driving component 5 to drive the cutter 6 to slice the annular medicine column 00, and use the equidistant feeding component 7 to achieve equidistant slicing.

[0028] In this embodiment, the semicircular medicine column 01 is processed into a 10 mm or 4 mm thick tablet. Fig.11 , 12 As shown, the semicircular medicine column 01 is placed on the slide 1, and the operator adjusts the position of the semicircular medicine column 01 and uses the rear end medicine pressing cylinder 82 to press the semicircular medicine column. The operator leaves and remotely controls the cutter to cut in the control room. Each time a cut is made, the gear mechanism 73 pushes the slide 1 forward by 10 mm or 4 mm until the cutting of the required medicine column sample is completed.

[0029] Example 1: According to the above sample preparation process, the annular grain column at the rear of the front combustion chamber is sampled, and the specifications of the mechanical tablets (10mm) and burning rate tablets (4mm) are as follows:

[0030] The thickness requirement of burning rate tablets is (4±0.5) mm; the thickness requirement of mechanical tablets is (10±0.5) mm. The specifications of 20 burning rate tablets and 20 mechanical tablets were analyzed, and the qualified rate was 100%, and the dimensional error was very small.

[0031] Example 2: According to the above sample preparation process, the annular grain column at the tail of the afterburner is sampled. The specifications of the mechanical tablets (10 mm) and burning rate tablets (4 mm) are as follows:

[0032] From the table above, we can see that the thickness requirement of the burning rate tablet is (4±0.5) mm; the thickness requirement of the mechanical tablet is (10±0.5) mm. The specifications of 20 burning rate tablets and 20 mechanical tablets were analyzed, and the qualified rate was 100%, and the dimensional error was very small.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
