[0002] Grain is an important component in rocket engines, made of a mixture of fuel and oxidizer. In order to ensure the safety and stability of the grain during transportation and use, it is necessary to take edge sealing measures for the grain. Generally speaking, the edge sealing process includes the following steps:

[0003] 1. Prepare edge banding materials: Select appropriate materials, such as metal foil, plastic film, etc., for edge banding.

[0004] 2. Wrap the medicine column: Wrap the medicine column tightly in the edge sealing material to ensure there is no gap or looseness.

[0005] 3. Fix the edge sealing material: Use appropriate fixing methods, such as welding, gluing, etc., to fix the edge sealing material on the powder column.

[0006] 4. Check the edge sealing effect: Check the medicine column after edge sealing to ensure that the edge sealing effect is good and there is no leakage or looseness.

[0007] In the prior art, such as Figure 6 As shown in the figure, the edge-sealed propellant usually has flash. In the process of removing the flash of the adhesive layer, most of the time, workers still use handheld methods, which has low pass rate and efficiency and poses certain safety hazards. Some processing devices can fix the propellant and drive the propellant to rotate, but before driving the propellant to rotate, no measures are taken to center the propellant, so the quality of the edge sealing cannot be guaranteed, and the safety and stability of the propellant during transportation and use cannot be ensured.

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a drug column clamping and rotating mechanism is provided, comprising a driving portion 301, a transmission portion, a rotating member 201 and a clamping portion, wherein a central placement position is provided on the rotating member 201, and the clamping portion comprises at least two clamping members, and at least two clamping members are arranged circumferentially along the central placement position, and the driving portion 301 is connected to the clamping member through the transmission portion to drive the clamping member to move synchronously toward the central placement position to clamp the drug column 503, and the rotating member 201 is connected to the driving portion 301 through the transmission portion so that the driving portion 301 drives the rotating member 201 to rotate.

[0034] By providing the driving part 301 and the transmission part, it is possible to provide power for the movement of the rotating part 201 and the clamping part. By providing the clamping part, and making the clamping part include at least two clamping members arranged along the circumference of the central placement position, and driving the clamping members to move synchronously toward the central placement position through the driving part 301 and the transmission part, it is possible to push the drug column 503 to the central placement position when the drug column 503 deviates from the central placement position, so that the drug column 503 is centered, and at the same time, the drug column 503 can be firmly clamped, thereby ensuring that the drug column 503 remains in the central placement position. By setting the rotating part 201, a centering position is provided for the medicine column 503, and the medicine column 503 can also be driven to rotate. The rotating part 201 cooperates with the clamping part to ensure that the medicine column 503 rotates stably in the centering position, and then the flash 501 on the glue layer 502 of the medicine column 503 can be cut by a cutting tool. There is no need to manually center the medicine column 503 and rotate the medicine column 503. It is convenient and quick to use, improves the cutting effect of the flash 501, ensures the quality of the edge sealing, and ensures the safety and stability of the medicine column 503 during transportation and use.

[0035] Among them, the rotating part 201 can be a disc-shaped part, and the center position is the center position of the rotating part 201, that is, the center position is concentric with the rotating part 201. When the rotating part 201 rotates, the medicine column 503 on the center position can rotate with the axis of the center position as the rotation center.

[0036] Specifically, the drug column 503 is cylindrical, and the drug column 503 is coaxially placed on the central placement position, that is, the drug column 503, the central placement position, and the rotating member 201 are all coaxially arranged. The rotating member 201 rotates with its own central axis as the rotation center, and when rotating, the drug column 503 in the central placement position rotates with its own central axis as the rotation center.

[0037] Among them, the number of clamping members is at least two, and the distance between each clamping member and the center of the central placement position is the same, and when the clamping member moves, it also maintains the same distance from the center of the central placement position, so that when each clamping member moves synchronously, the medicine column 503 can be pushed to the center position of the central placement position, so that the medicine column 503 is coaxial with the central placement position.

[0038] The clamping members are evenly arranged along the circumference of the central placement position, so that the clamping members can push the medicine column 503 to the central placement position and clamp the medicine column 503.

[0039] Specifically, in the present embodiment, the number of the clamping members is three, the three clamping members are evenly arranged along the circumference of the central placement position, and the three clamping members maintain the same distance from the center of the central placement position, that is, before, during and after movement, the three clamping members are at the same distance from the center of the central placement position.

[0040] The driving part 301 includes a driving motor, which is connected to the clamping member through a transmission part, and the output shaft of the driving motor can rotate in a first direction to drive the clamping member to move synchronously toward the central placement position through the transmission part. The output shaft of the driving motor can rotate in a second direction to drive the clamping member to move synchronously in a direction away from the central placement position through the transmission part. The first direction is opposite to the second direction.

[0041] By setting a driving motor and driving the rotating member 201 to rotate in the first direction and the second direction, the transmission part can drive the clamping member to move synchronously toward the central placement position and in a direction away from the central placement position, so that the clamping member clamps or releases the drug column 503.

[0042] The first direction and the second direction are two opposite circumferential directions of the motor shaft. For example, the first direction is the forward rotation direction of the motor shaft, and the second direction is the reverse rotation direction of the motor shaft.

[0043] When the output shaft of the driving motor can rotate in the first direction, it can drive the rotating member 201 to rotate in the second direction. When the output shaft of the driving motor can rotate in the second direction, it can drive the rotating member 201 to rotate in the first direction.

[0044] The stator and rotor ends of the driving motor are arranged on a carrier that does not rotate with the rotating member 201, and the motor shaft of the driving motor is arranged vertically. The first direction and the second direction are two opposite horizontal circumferential directions of the motor shaft.

[0045] The transmission part includes a driving bevel gear 302 and a lead screw 209. The driving bevel gear 302 is connected to the driving part 301. The lead screw 209 is provided with a driving bevel gear 303. The driving bevel gear 303 is meshed with the driving bevel gear 302. The clamping part is threadedly sleeved on the outer peripheral side of the lead screw 209 so that the driving part 301 can drive the clamping part to move in a direction toward or away from the central placement position through the driving bevel gear 302, the transmission bevel gear 303 and the lead screw 209.

[0046] By providing the driving bevel gear 302 , the transmission bevel gear 303 and the lead screw 209 , it is possible to stably transmit the power generated by the driving part 301 to the clamping part, and drive the clamping part to move in a direction toward or away from the central placement position.

[0047] The driving bevel gear 302 is coaxially arranged with the output shaft of the driving motor, so that the driving bevel gear 302 rotates coaxially and synchronously with the output shaft of the driving motor.

[0048] Specifically, in this embodiment, the axial directions of the driving bevel gear 302 and the output shaft of the driving motor are both vertical.

[0049] The transmission bevel gear 303 is coaxially sleeved on the lead screw 209 .

[0050] Specifically, in this embodiment, the axial directions of the transmission bevel gear 303 and the corresponding lead screw 209 are both horizontal.

[0051] The transmission bevel gear 303 and the lead screw 209 form a group, and each group of the transmission bevel gear 303 and the lead screw 209 is arranged in one-to-one correspondence with the clamping piece of the clamping part.

[0052] Specifically, the clamping portion includes at least two clamping members, the number of the clamping members is the same as the number of the lead screws 209 and they are arranged in one-to-one correspondence, and each lead screw 209 is sleeved with a transmission bevel gear 303 .

[0053] More specifically, in this embodiment, there are three clamping members, and there are also three lead screws 209. The clamping members are arranged in one-to-one correspondence with the lead screws 209, and each lead screw 209 is sleeved with a transmission bevel gear 303. The clamping members are threadedly sleeved on the corresponding lead screws 209, and the lead screws 209 are connected to the driving bevel gear 302 through the corresponding transmission bevel gears 303. The driving motor drives the driving bevel gear 302 to rotate, and synchronously drives the three transmission bevel gears 303 that are simultaneously meshed with the driving bevel gear 302 to rotate, and then can drive the three lead screws 209 to rotate, so that the three clamping members that are respectively threadedly sleeved on the lead screws 209 move synchronously in the direction toward or away from the central placement position.

[0054] The three lead screws 209 and the corresponding three transmission bevel gears 303 are evenly arranged along the circumference of the driving bevel gear 302. That is, the angle between adjacent lead screws 209 is 120°.

[0055] The transmission bevel gear 303 is sleeved on the outer peripheral wall of one end of the lead screw 209 close to the driving bevel gear 302. The outer peripheral wall of the lead screw 209 close to the driving bevel gear 302 is provided with a first ratchet structure 210. The inner peripheral wall of the transmission bevel gear 303 is provided with a second ratchet structure 211 matched with the first ratchet structure 210. The tooth tip of the first ratchet structure 210 is inclined along the first circumferential direction, and the tip angle of the second ratchet structure 211 is inclined along the second circumferential direction, so that the second ratchet structure 211 can drive the first ratchet structure 210 to rotate along the second circumferential direction. The first ratchet structure 210 is provided with a clamping hook 212, and the second ratchet structure 211 is provided with a clamping groove. The clamping hook 212 can extend into the clamping groove, so that the second ratchet structure 211 can drive the first ratchet structure 210 to rotate along the first circumferential direction.

[0056] By setting the first ratchet structure 210 and the second ratchet structure 211, the transmission bevel gear 303 can drive the screw 209 to rotate along the second circumferential direction. By setting the clamping hook 212 and the clamping groove, the transmission bevel gear 303 can drive the screw 209 to rotate along the first circumferential direction, that is, drive the clamping part to move synchronously in the direction toward or away from the central placement position, so as to realize automatic clamping or loosening of the drug column 503 and avoid manual operation of reversing.

[0057] Among them, the driving part 301 drives the driving bevel gear 302 to rotate along the first direction, and the driving bevel gear 302 drives the transmission bevel gear 303 to rotate along the second circumferential direction. The transmission bevel gear 303 exerts pressure on the first ratchet knot along the second circumferential direction through the second ratchet structure 211, thereby driving the first ratchet structure 210 and the screw 209 to rotate along the second circumferential direction, and at this time drives the clamping part to move synchronously in the direction away from the central placement position.

[0058] Among them, the driving part 301 drives the driving bevel gear 302 to rotate along the second direction, and the driving bevel gear 302 drives the transmission bevel gear 303 to rotate along the first circumferential direction. The transmission bevel gear 303 applies pressure along the first circumferential direction to the clamping hook 212 extending into the clamping groove through the clamping groove, thereby driving the first ratchet structure 210 and the lead screw 209 to rotate along the first circumferential direction, and at this time drives the clamping part to move synchronously in the direction toward the center placement position.

[0059] The engaging hook 212 may be disposed on the tooth wall at the tip of the first ratchet structure 210. The engaging groove may be disposed at the groove bottom of the tooth groove of the second ratchet structure 211. When the first ratchet structure 210 and the second ratchet structure 211 are meshed, the engaging hook 212 is inserted into the engaging groove.

[0060] The transmission part also includes a driven bevel gear 304, which meshes with the transmission bevel gear 303 so that the driving bevel gear 302 can drive the driven bevel gear 304 to rotate through the transmission bevel gear 303, and the driven bevel gear 304 is connected to the rotating member 201 so that the rotating member 201 and the driven bevel gear 304 rotate synchronously.

[0061] By providing a driven bevel gear 304 and making the driven bevel gear 304 mesh with the transmission bevel gear 303, the rotating member 201 can be stably rotated synchronously with the driven bevel gear 304, the transmission bevel gear 303 and the driving bevel gear 302, and then the clamping part and the rotating member 201 can be driven to rotate by one driving motor, thereby saving the number of driving motors and reducing the manufacturing cost.

[0062] The driven bevel gear 304 is coaxially arranged with the driving bevel gear 302 .

[0063] The transmission bevel gear 303 is disposed between the driven bevel gear 304 and the driving bevel gear 302 , and the transmission bevel gear 303 is meshed with both the driven bevel gear 304 and the driving bevel gear 302 .

[0064] The axes of the driven bevel gear 304 and the driving bevel gear 302 are both vertical, and the axis of the transmission bevel gear 303 is horizontal.

[0065] The sizes and the numbers of teeth of the driven bevel gear 304 and the driving bevel gear 302 may be equal or different, and can be flexibly set according to requirements.

[0066] The clamping hook 212 is made of elastic material. When the clamping member clamps the medicine column 503 and the second ratchet structure 211 applies force to the first ratchet structure 210 along the first circumferential direction, the clamping hook 212 can escape from the clamping groove, so that the driving bevel gear 302 can drive the driven bevel gear 304 to rotate through the transmission bevel gear 303 when the lead screw 209 does not rotate with the transmission bevel gear 303.

[0067] By setting the snap-on hook 212 to be made of an elastic material, when the pressure applied by the second ratchet structure 211 to the first ratchet structure 210 along the first circumferential direction is greater than the elastic force that keeps the snap-on hook 212 in shape unchanged, the snap-on hook 212 can be disengaged from the snap-on groove, and then the driving bevel gear 302 can drive the driven bevel gear 304 to rotate through the transmission bevel gear 303 without the lead screw 209 rotating with the transmission bevel gear 303, and then the medicine column 503 can be driven to rotate while the medicine column 503 is clamped.

[0068] Among them, although the clamping hook 212 is out of the clamping groove, the clamping hook 212 rotates continuously with the transmission bevel gear 303, and can still enter different clamping grooves in sequence and continuously escape from the clamping grooves, thereby intermittently applying force to the first ratchet structure 210 along the first circumferential direction, so that the clamping member can clamp the medicine column 503. In addition, the clamping hook 212 is pressed against the second ratchet structure 211, and friction is continuously generated between the clamping hook 212 and the second ratchet structure 211. Through the friction between the clamping hook 212 and the second ratchet structure 211, the clamping member can also clamp the medicine column 503.

[0069] Among them, a sufficient number of clamping hooks 212 and clamping grooves can be set according to needs, and with the appropriate rotation speed of the transmission bevel gear 303, the powder column 503 can be clamped.

[0070] Among them, all the engaging hooks 212 are arranged opposite to each other in the circumferential direction of the lead screw 209 , and all the engaging grooves are arranged opposite to each other in the circumferential direction of the lead screw 209 .

[0071] The clamping hook 212 is made of a material with suitable elastic force, and the clamping force on the drug column 503 is determined by the elastic force of the clamping hook 212 itself.

[0072] Specifically, the snap hook 212 may be made of rubber.

[0073] The clamping member includes an arc plate 202 and an air cushion 203. The arc opening of the arc plate 202 is arranged toward the medicine column 503. The air cushion 203 is arranged on the arc inner wall of the arc plate 202, so that the air cushion 203 is located between the arc plate 202 and the medicine column 503 when the medicine column 503 is clamped. By arranging the arc plate 202 and arranging the arc opening of the arc plate 202 toward the medicine column 503, the clamping member can be more closely fitted to the outer peripheral wall of the medicine column 503, thereby ensuring a good clamping effect. By arranging the air cushion 203 on the arc inner wall of the arc plate 202, the clamping member can be further closely fitted to the medicine column 503.

[0074] The arc-shaped plates 202 and the air cushions 203 of each clamping member are identical.

[0075] The arc-shaped inner wall of the arc-shaped plate 202 is also the groove wall of the groove formed by the arc-shaped plate 202 , that is, the wall surface of the arc-shaped plate 202 facing the medicine column 503 .

[0076] The air pressure in the air cushion 203 is adjustable.

[0077] Specifically, the arc plate 202 is bent in the horizontal direction to form an arc, and the curvature of the arc plate 202 is adapted to the medicine column 503 .

[0078] After each arc-shaped plate 202 clamps the drug column 503 , gaps may be left between adjacent arc-shaped plates 202 .

[0079] A plurality of protrusions 204 are provided on one side of the air cushion 203 facing the medicine column 503 , so as to facilitate the deformation of the air cushion 203 and thereby fit the surface of the medicine column 503 .

[0080] A plurality of grooves are arranged in the transverse and longitudinal directions on the surface of the air cushion 203 facing the medicine column 503 , thereby separating a plurality of protrusions 204 on the surface of the air cushion 203 .

[0081] The plurality of protrusions 204 are evenly arranged on the surface of the air cushion 203 facing the medicine column 503 .

[0082] The internal gas of the air cushion 203 of each clamping member is connected through the conduit 205, so that the internal air pressure of the air cushion 203 of each clamping member is the same, and then the clamping force of each clamping member on the medicine column 503 is the same, ensuring that the medicine column 503 is in the middle of the central placement position and ensuring that the medicine column 503 is evenly stressed and not damaged.

[0083] The internal gases of the air cushions 203 of adjacent clamping parts are connected through the conduit 205 to form a ring.

[0084] Multiple groups of air cushions 203 are arranged on each arc plate 202, and each group of air cushions 203 is respectively provided with an elastic mechanism, and the elastic mechanism applies an elastic force to the corresponding air cushion 203 in the direction toward the medicine column 503. The elastic mechanism includes a support block 401 and an elastic telescopic rod 402, and the support block 401 extends along the extension direction of the corresponding air cushion 203, and is used to abut against the corresponding air cushion 203. The support block 401 is arranged at the movable end of the elastic telescopic rod 402, and the elastically telescopic fixed end is connected to the arc plate 202. By arranging the support block 401 and the elastic telescopic rod 402, it can be further ensured that each arc plate 202 has a good fitting effect on the medicine column 503. When the medicine column 503 is an arc cone-shaped medicine column 503 or a frustum-shaped medicine column 503, the contact area and friction force can be increased as much as possible, thereby improving the stability of the shaping of the flash 501 of the medicine column 503.

[0085] Among them, the elastic telescopic rod 402 includes an inner tube sleeve and an outer tube sleeve. The inner tube sleeve can be provided with elastic force by a spring, and then the air cushion 203 is pressed against the medicine column 503 through the support block 401, so that the air cushion 203 can fit the outer wall of the medicine column 503 of different shapes to increase stability.

[0086] The support block 401 is roughly similar in shape to the corresponding air cushion 203 , so that the support block 401 can provide good support and compression for the air cushion 203 .

[0088] More specifically, in this embodiment, each group of air cushions 203 extends in the horizontal direction into a long strip, and the corresponding support block 401 extends in the horizontal direction into a long strip.

[0089] It is understandable that each protrusion 204 can correspond to an elastic mechanism, that is, each protrusion 204 can form a group of air cushions 203. It is not only applicable to arc cone-shaped medicine column 503, but also to frustum-shaped medicine column 503. By increasing the contact area and friction, the movement and deformation of medicine column 503 during processing can be reduced, thereby improving production efficiency and product quality. It can also reduce the impact of manual operation on medicine column 503, reduce the impact of human factors on product quality, and meet the requirements of modern mechanical processing, can adapt to the needs of large-scale production, can improve the stability of the shaping of flash 501 of medicine column 503, and improve production efficiency and product quality.

[0091] By providing the slide groove, a guide is provided for the movement of the clamping member. By providing the sliding block 207 and the ball 208, the friction force during sliding is reduced and the smoothness of sliding is increased.

[0092] The clamping member includes a bracket 206 , one end of the bracket 206 is fixedly connected to the arc plate 202 , and the other end of the bracket 206 passes through a slide groove and is connected to the lead screw 209 .

[0094] The sliding block 207 is disposed on the top surface of the rotating member 201 .

[0095] Specifically, the sliding block 207 abuts against the top surface of the rotating member 201 through the ball bearing 208 .

[0096] In another aspect of the present embodiment, a device for shaping the flash edge of the drug column glue layer is provided, comprising the drug column clamping and rotating mechanism as described above.

[0097] The drug column glue layer flash shaping device includes a cutting mechanism and a base 101, a driving part 301 and a rotating part 201 are arranged on the base 101, a transmission part and a clamping part are arranged on the rotating part 201, and a cutting mechanism is arranged on the base 101 and can move toward or away from the drug column 503.

[0098] By setting up a medicine column clamping and rotating mechanism, and the multiple clamping parts in the medicine column clamping and rotating mechanism can move synchronously, the medicine column 503 can be clamped in the center and driven to rotate. The flash 501 of the medicine column 503 can be removed and shaped by pushing the tool 104 into cutting. There is no need to manually center the medicine column 503 and rotate the medicine column 503, which is convenient and quick to use.
