Description

Technical Field

[0001] This utility model belongs to the field of solid rocket motor manufacturing technology, specifically relating to a transfer system in the manufacturing and forming process of an engine end cover layer. Background Technology

[0002] End cap coating involves adding a pre-mixed end cap coating slurry to the part of the engine where the end cap coating needs to be made. Through a cross-linking and curing reaction, an end cap coating with certain mechanical properties, ablation resistance, flame retardancy, and sealing is formed, which is an important guarantee for the safe flight of the engine.

[0003] Vertical casting is one of the main molding methods for end cap coatings. The process is as follows: after the operator places the engine vertically, the pre-mixed end cap coating slurry is added to the coating area, and cross-linking and curing occur under the process environment conditions to complete the manufacturing of the end cap coating.

[0004] Currently, vertical casting molding of end-face coatings is mainly an in-situ operation. This involves placing the engine vertically at the work station, adding pre-mixed end-face coating slurry to the coating area, and then leaving the engine in place until the slurry undergoes a cross-linking reaction, completing the end-face coating manufacturing. Because the cross-linking and curing reaction of the end-face coating slurry requires high temperatures, performing the slurry addition operation in situ poses certain safety hazards. Therefore, it is necessary to separate the end-face coating slurry addition operation from the cross-linking and curing operation area.

[0005] The end-coating slurry has high fluidity. When initially added to the engine coating area, its high fluidity causes slurry overflow into non-coated areas during manual engine transfer. Furthermore, the vertically cast end-coating requires high flatness (circumferential dimensional difference ≤0.1mm). Manual engine transfer causes the slurry to bounce upon initial addition to the coating area, failing to meet the flatness requirements of the formed end-coating surface. Therefore, there is an urgent need to research an end-coating forming and transfer system that enables vertical casting, cross-linking, and zoned curing of the engine, allowing for stable and automatic transfer of the engine after the addition of the end-coating slurry. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] The technical problem to be solved by this utility model is: how to realize the zoned transfer of the engine in the vertical casting and cross-linking curing process.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides an end-face coating forming and transfer system, including a bracket 1, an adjustment platform 2, a platform trolley 3, a trolley track 4, and a servo motor 5; the platform trolley 3 is set on the trolley track 4 and is connected to the servo motor 5 through a chain mechanism; the adjustment platform 2 is horizontally fixed on the top of the platform trolley 3 and is used to place the engine; several brackets 1 are fixed between the columns on the top of the platform trolley 3; the brackets are "V" shaped plates; a locking device is installed on the bracket 1 to constrain the side of the vertically placed engine to the "V" shaped plate.

[0010] Furthermore, the adjustment platform 2 includes a support base plate 9 and an adjustment nut 10; the support base plate is fitted onto the adjustment nut by four equal-height pads at the four corners, and the horizontal accuracy of the support base plate is adjusted by adjusting the position of the adjustment nut on the fixing bolt.

[0011] Furthermore, the entire "V"-shaped plate is covered with rubber or cowhide.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: it can realize the smooth operation of the end coating slurry after it is added to the engine coating area to the cross-linking and curing zone, thereby completing the end coating manufacturing.

[0014] The workers installed the leveling pads on the four corners of the support base plate onto the fixing bolts. By adjusting the adjusting nuts on the fixing bolts, the workers ensured that the surface of the support base plate was level enough to meet the covering requirements. After confirming that the plate was level, the workers placed the engine vertically on the support base plate, relying on the "V" shaped plate of the bracket. Based on the engine height, the workers installed the corresponding locking device on the bracket to fix the engine to the adjustment platform.

[0015] The platform trolley is connected to the adjustment platform via fixing bolts at the top and to the chain via a connecting device at the bottom. During engine transfer, the servo motor rotates, driving the chain to rotate on the sprocket, thus meeting the transfer requirements of the platform trolley for forward and backward movement. The platform trolley runs smoothly within the trolley track, effectively ensuring the molding quality of the end-face coating and meeting the requirement that the circumferential spatial dimension deviation of the end-face coating after molding is ≤0.1mm. The servo motor and the platform trolley are designed separately; the servo motor is independent of the platform trolley and installed in the vertical casting area, effectively preventing the servo motor from entering the cross-linking curing zone with the platform trolley and extending the service life of the servo motor.

[0020] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0021] The end-face coating forming and transfer system of this embodiment mainly consists of a bracket 1, an adjustment platform 2, a platform trolley 3, a trolley track 4, a servo motor 5, a chain 6, a sprocket 7, and a connecting device 8. The adjustment platform 2 consists of a support base plate 9, an adjustment nut 10, and a fixing bolt 11.

[0022] The bracket, adjustment platform, platform trolley, servo motor and chain, and sprocket are connected in sequence from top to bottom.

[0023] The support bracket serves as the base for the engine when placed vertically, providing support during engine transport and ensuring it does not tip over. The bracket is equipped with upper and lower locking devices, which can be installed separately or simultaneously depending on the engine height, ensuring the engine remains upright, does not tip over, and does not fall during transport. The bracket is a "V"-shaped plate mounted sideways on the platform trolley's uprights. The "V"-shaped opening is entirely covered with soft materials such as rubber or leather. The "V"-shaped plate design accommodates engines of different diameters, and the soft covering effectively prevents damage to the engine casing during transport. The locking device uses straps to restrain the engine, allowing it to rest on the adjustment platform.

[0024] The adjustment platform serves as the base for vertical engine mounting, providing support for this configuration. The platform consists of a support base plate, adjusting nuts, and fixing bolts. The support base plate is fitted onto the adjusting nuts via four equal-height shims at its four corners. By adjusting the position of the adjusting nuts on the fixing bolts, the required levelness of the support base plate can be achieved.

[0025] The platform trolley is a single unit, assembled with the adjustment platform at the top using fixing bolts, and connected to the chain at the bottom via a connecting device. A servo motor provides power, driving the sprockets and chain to move the platform trolley smoothly within the trolley track.

[0026] The working process is as follows: The transfer system is moved to the end-coating slurry feeding area. The transfer system is then stopped. The positions of the adjusting bolts are pre-adjusted to ensure the support base plate is level. The engine is placed vertically on the horizontal support base plate, with one side of the engine resting against the "V"-shaped plate of the bracket. Upper and lower locking devices are installed separately or simultaneously according to the engine height to ensure the engine is securely fixed to the platform trolley. The pre-mixed end-coating slurry is added to the coating area. The transfer system is then activated, and the servo motor drives the chain and sprockets, causing the engine to enter the cross-linking curing zone. After the end-coating slurry cross-links and cures, the end-coating manufacturing is complete.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
