Description

Technical Field

[0001] The utility model relates to the technical field of melt-cast explosive technology, in particular to a cutting frame for shaping explosive surfaces. Background Art

[0002] When used, cast explosives are loaded into warheads of different shapes and sizes according to different destructive purposes to achieve corresponding destructive effects. During the manufacturing and post-processing of the charge, the end faces of the cast and poured charge need to be shaped with high precision to facilitate their subsequent assembly and application.

[0003] Due to the explosiveness of explosives, the surface trimming of explosives is highly dangerous. Since the performance of the explosive column is highly sensitive to the end face shaping accuracy, the existing cutting equipment has the problem of low end face shaping accuracy.

[0004] For example, the prior art application number: 201620106311.0 is a CNC equipment for shaping solid rocket engine grains. However, when its structure realizes the end face cutting of the grain surface through the cooperation of the X-axis moving mechanism and the Y-axis moving mechanism, the edge of the grain surface is not taken into account, resulting in the problem of low-precision shaping of the end face. Utility Model Content

[0005] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages to be described hereinafter.

[0006] In order to achieve these purposes and other advantages according to the present invention, a cutting frame for shaping a medicine surface is provided, comprising:

[0007] The slewing support is a hollow disc, and the structure of the slewing support includes:

[0008] a chassis, which is a hollow disc;

[0009] an electric turntable, which is provided with a first set of servo motors and is slidably mounted on the chassis;

[0010] An X-axis electric screw slide, the base of which is mounted on the electric turntable;

[0011] A Z-axis electric screw slide, the base of which is mounted on the slide of the X-axis electric screw slide;

[0012] A milling cutter group is arranged on the base of the Z-axis electric screw slide, the slide of the Z-axis electric screw slide is vertically fixed to the slide of the X-axis electric screw slide, and two groups of slides of the Z-axis electric screw slide are symmetrically arranged about the milling cutter group.

[0013] Preferably, the structure of the milling cutter assembly includes:

[0014] a hollow main shaft on which a second set of servo motors is mounted;

[0015] an air inlet, which is arranged on a side of the hollow main shaft;

[0016] A hollow tool is arranged at the bottom end of the hollow spindle, and the hollow tool is communicated with the air inlet.

[0017] Preferably, a dust suction cover is provided on the hollow tool, and a hollow dust suction channel is provided on the side of the dust suction cover, and the dust suction channel is connected to the dust suction port pipe of the water bath explosion-proof vacuum cleaner.

[0018] The utility model has at least the following beneficial effects:

[0019] The adoption of rotary support, X-axis electric screw slide, and Z-axis electric screw slide can achieve multi-angle trimming of the medicine surface without dead angles;

[0020] The milling material is dangerously hot, so the milling cutter is hollow and has cooling air flowing through the center to cool the cutting tool and the powder surface, thus avoiding overheating and explosion hazard in the contact area between the cutter head and the powder column.

[0021] A dust collection cover is designed above the shaping hollow main shaft, which uses micro-negative pressure to automatically collect the powder chips. The water bath explosion-proof vacuum cleaner in the dust collection channel can achieve real-time dust absorption, avoiding the danger caused by the flying of explosive dust.

[0036] The following is a detailed description of this experimental model with reference to the accompanying drawings:

[0037] Figure 1-8 The present invention shows a cutting frame for shaping the medicine surface, comprising:

[0038] The rotary support 10 is a hollow disc, and the structure of the rotary support 10 includes:

[0039] The chassis 101 is a hollow disc;

[0040] An electric rotary disk 102 is provided with a first set of servo motors 103 and is slidably mounted on the chassis 101;

[0041] The X-axis electric screw slide 20, whose base 201 is installed on the electric rotary disk 102;

[0042] The Z-axis electric screw slide 30, whose base 301 is installed on the slide 202 of the X-axis electric screw slide 20;

[0043] The milling cutter group 40 is arranged on the base 301 of the Z-axis electric screw slide. The slide 302 of the Z-axis electric screw slide is vertically fixed to the slide 202 of the X-axis electric screw slide, and the slides 302 of the Z-axis electric screw slide are symmetrically arranged in two groups about the milling cutter group 40.

[0044] Working principle:

[0045] Before using the device of the utility model, the cutting frame for shaping the medicine surface is fixed on the end face of the medicine column through the external support frame.

[0046] The rotary support 10 can drive the electric rotary disk 102 through the first group of servo motors 103, and perform circular motion around the medicine column with the end face of the medicine column as the center of the circle to achieve the precision trimming of the end face of the medicine column. The electric rotary disk 102 cooperates with the X-axis electric screw slide 20 to achieve the two-dimensional precision trimming of the X·Y plane of the medicine column end face. The X-axis electric screw slide 20, the electric rotary disk 102 and the Z-axis electric screw slide 30 cooperate to achieve the three-dimensional precision trimming of the X·Y·Z stereoscopic end face of the medicine column. Specifically:

[0047] By driving the second set of servo motors 402 on the hollow spindle 401, the hollow tool 404 rotates to start the surface trimming operation. At this time, the entire device, the slide 302 on the Z-axis electric screw slide 30 is vertically fixed to the slide 202 of the X-axis electric screw slide. At this time, the base 301 of the Z-axis electric screw slide moves vertically up and down along the slide 302, so that the milling cutter group 40 moves vertically along the Z axis in the vertical direction of the end face of the medicine column, and then the slide 202 of the X-axis electric screw slide drives the Z-axis electric screw slide 30, so that the milling cutter group 40 moves horizontally along the X axis on the water surface. By connecting the electric turntable 102 to the base 201 of the X-axis electric screw slide, the milling cutter group 40 makes a circular motion around the medicine column with the end face of the medicine column as the center of the circle, thereby completing high-precision trimming of the end face of the medicine column.

[0048] The three sets of mechanisms of the X-axis electric screw slide 20, the Z-axis electric screw slide 30, and the electric rotary disk 102 of the utility model are linked together with the rotation of the hollow tool 404 to achieve complex repair of the end face of the grain column;

[0049] Among them, the X-axis electric screw slide 20 and the Z-axis electric screw slide 30 are both existing technologies or commercially available products, and their specific structures will not be elaborated in detail herein.

[0050] As in the above solution, the structure of the milling cutter group 40 includes:

[0051] A hollow main shaft 401 is provided with a second set of servo motors 402;

[0052] An air inlet 403 is provided on a side of the hollow main shaft 401;

[0053] The hollow tool 404 is disposed at the bottom end of the hollow spindle 401 , and the hollow tool 404 is connected to the air inlet 403 .

[0054] Working principle:

[0055] The second servo motor 402 can drive the hollow tool 404 connected to the bottom end of the hollow spindle 401 to rotate, and through the cooperation of the slide 202 of the X-axis electric screw slide, the electric rotary disk 102 and the slide 302 of the Z-axis electric screw slide, the hollow tool 404 is controlled to achieve three-dimensional precision trimming of the end surface of the grain in X, Y and Z directions;

[0056] The milling cutter assembly 40 is controlled to move downward by the Z-axis displacement mechanism 30, and is controlled to move horizontally along the X-axis by the slide 202 of the X-axis electric screw slide. Then, the electric rotary disk 102 is used to continue to make circular motion in the radial direction to the edge of the medicine surface. This process is repeated until the trimming depth reaches the set total trimming depth of the medicine surface. The cutting three-dimensional displacement assembly 1 returns to the origin, and the medicine surface trimming is completed.

[0057] The workpiece is reshaped by milling. According to the use requirements, the hollow tool 404 is a rotary milling cutter, and is made of copper material. The specially designed special milling cutter has the function of anti-collision edge.

[0058] The high temperature generated by the hollow tool 404 during cutting also needs to be protected. The milled material has a high temperature hazard. Therefore, in actual use, an infrared temperature sensor 407 can be added to the bottom of the rotary milling cutter to monitor the temperature change of the tool tip during the milling process. At the same time, the rotary milling cutter has a hollow structure. Cooling air is passed to the center of the hollow tool 404 through the air inlet 403 connected to the side of the hollow spindle 401 to cool the cutting tool and the powder surface, thereby avoiding overheating and explosion risk in the contact area between the tool head and the powder column.

[0059] As in the above solution, the hollow tool 404 is provided with a dust suction cover 405, which is sleeved on the hollow tool 404, and a hollow dust suction channel 406 is provided on the side of the dust suction cover 405, and the dust suction channel 406 is connected to the dust suction port pipe of the water bath explosion-proof vacuum cleaner.

[0060] Working principle:

[0061] During the milling process, the milling chips need to be processed. A dust collection cover 405 is designed on the hollow tool 404, which uses a slight negative pressure to automatically collect the chips. The milling chips pass through the hollow dust collection channel 406 and enter the dust collection port of the water bath explosion-proof vacuum cleaner connected to the pipeline. The dust collection channel is made of 406 stainless steel to prevent static electricity accumulation during the adsorption process.

[0062] The vacuum cleaner is a water-bath explosion-proof vacuum cleaner. This type of vacuum cleaner uses vacuum to absorb dust. Dust is then deposited into a sealed dust chamber within the vacuum cleaner through a vacuum line. No dust escapes during the entire operation, thus achieving the goal of dust absorption and environmental purification. The absorbed dust is deposited in a sealed environment and can be directly deposited in water, fully meeting the high standards of powder explosion protection.

[0063] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
