Description

Technical Field

[0001] This invention belongs to the field of aerospace spinning equipment technology, specifically, it relates to a multifunctional composite spinning equipment for forming rocket tube-like structural components. Background Technology

[0002] Spinning has become an important process in rocket structure manufacturing in recent years. Previously, parts such as end frames, shell sections, skins, and stringers to be riveted were pre-assembled on a jig, then manually drilled and countersunk, followed by manual insertion of rivets, and finally manual riveting. Driven by the urgent need for automated drilling and riveting technology, aerospace manufacturing companies have gradually begun to introduce automated drilling and riveting equipment in recent years, striving to replace manual riveting and improve rocket production efficiency. However, rocket cabin parts have large roundness errors during machining, and drilling and riveting based on forced deformation of the parts is unsuitable for thick, difficult-to-deform parts (such as shell sections). Automated drilling and riveting equipment also frequently experiences problems such as stuck rivets, misaligned rivets, and rivets failing to insert, leading to downtime.

[0003] Patent document CN119608918A discloses a pipe forming equipment, relating to the field of pipe forming technology, including a base, a control box, and pipes. The control box has an installation groove, in which a spinning auxiliary component is installed. A reciprocating screw is rotatably mounted on the control box. A support block is fixedly mounted on the base, and one end of the reciprocating screw passes through the control box and is rotatably mounted on the support block. A transmission component is installed between the reciprocating screw and the spinning auxiliary component.

[0004] However, the forming equipment described in patent document CN119608918A is not suitable for parts that are thick and difficult to deform, and lacks the ability to perform strong spinning operations on pipes.

[0005] To address this issue, an integrated equipment was developed for the strong spinning forming of tubular structural components such as rocket ducts and gas cylinders, as well as the conventional spinning forming of gas cylinder necks. This equipment features both hot and wet spinning modes to handle thick, difficult-to-deform parts. Therefore, this invention designs a composite spinning equipment for forming rocket tube structural components, solving the aforementioned problems. Summary of the Invention

It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0055] The main spindle box 11, the closing spindle box 12, the tailstock 13, and the spinning wheel frame 15 are mounted on the bed 14;

[0056] The main spindle box 11 has active power and can achieve controllable rotation;

[0066] The hydraulic station 9 provides high-pressure oil to the main spindle box 11, the closing spindle box 12, and the tail jack 13 to realize the functions of shifting, clamping, and tightening.

[0067] The circulating filter device 111 sprays cutting fluid onto the workpiece and realizes the circulating filtration of the cutting fluid, thereby achieving wet strong spinning and improving the spinning quality.

[0068] When strong rotation is required, the mold and product are clamped between the main spindle box 11 and the tail 13. The main spindle box 11 drives the mold and product to rotate, and the tail 13 follows the main spindle box 11. The rotating wheel frame 15 drives the rotating wheel to achieve strong rotation of the product.

[0069] When it is necessary to perform general spinning such as closing and pressing, the closing spindle box 12 is hoisted to the corresponding position on the bed 14, and the main spindle box 11 and the closing spindle box 12 are connected by the coupling 1206 to realize the controllable rotation of the closing spindle box 12. The spinning wheel frame 15 drives the spinning wheel to realize the closing and pressing of the product.

[0070] See Figure 3 The main spindle box 11 includes a power unit 1101, a first housing 1102, a main shaft 1103, a first gear 1104, a first clutch 1105, a transmission shaft bearing assembly 1106, a faceplate 1107, a rotary cylinder 1108, a first transmission shaft 1109, a second transmission shaft 1110, a main spindle bearing assembly 1111, a second clutch 1112, a second gear 1113, a third gear 1114, a fourth gear 1115, a fifth gear 1116, and a sixth gear 1117.

[0071] The first clutch 1105, the third gear 1114, and the fifth gear 1116 are sequentially mounted on the first drive shaft 1109. The two ends of the first drive shaft 1109 rotate within the first housing 1102 via the drive shaft bearing assembly 1106. The drive shaft bearing assembly 1106 bears axial force, radial force, and tangential force. The power component 1101 inputs power to the first drive shaft 1109.

[0072] The fourth gear 1115, the second gear 1113, the sixth gear 1117, and the second clutch 1112 are sequentially mounted on the second drive shaft 1110. The two ends of the second drive shaft 1110 rotate within the first housing 1102 via the drive shaft bearing assembly 1106. The drive shaft bearing assembly 1106 bears axial force, radial force, and tangential force.

[0073] The flower disc 1107, the first gear 1104, and the rotary cylinder 1108 are sequentially arranged on the main shaft 1103. The two ends of the main shaft 1103 rotate within the first housing 1102 through the main shaft bearing assembly 1111. The main shaft bearing assembly 1111 bears axial force, radial force, and tangential force.

[0074] The first gear 1104 and the second gear 1113 are always meshed, the third gear 1114 and the fourth gear 1115 are always meshed, and the fifth gear 1116 and the sixth gear 1117 are always meshed.

[0075] The transmission ratio is changed by controlling the engagement and disengagement of the first clutch 1105 and the second clutch 1112, thereby realizing the spindle speed change. When both the first clutch 1105 and the second clutch 1112 are disengaged, the main spindle box 11 is in neutral. When the first clutch 1105 is disengaged and the second clutch 1112 is engaged, the main spindle box 11 is in high gear. When the first clutch 1105 is engaged and the second clutch 1112 is disengaged, the main spindle box 11 is in low gear. During the gear shifting process, since all transmission gears are always in a meshed state, there is no meshing impact.

[0076] See Figure 5 The closing spindle box 12 includes a second box body 1201, a closing spindle 1202, a closing bearing assembly 1203, a push-pull shaft 1204, a push-pull rod 1205, a coupling 1206, and a closing clamp;

[0079] See Figure 4 , Figure 5 The main shaft 1103 is a hollow shaft, and the coupling 1206 is hollow, allowing the push-pull rod 1205 to pass through. The push-pull rod 1205 is connected to the end rotary cylinder 1108, and the push-pull rod 1205 is connected to the push-pull shaft 1204 by screws or other means. By controlling the rotary cylinder 1108, the push-pull rod 1205 can move forward and backward, driving the push-pull shaft 1204 to move forward and backward, thereby realizing the clamping and releasing of the product by the closing clamp.

[0080] See Figure 6 The tail top 13 includes a third housing 1301, a clamping cylinder 1302, a clamping bearing assembly 1303, a motor 1304, a clutch 1305, a clamping head 1306, a limit cylinder 1307, a limit block 1308, and a limit rack 1309.

The clamping head 1306 can rotate relative to the clamping cylinder 1302 through the clamping bearing assembly 1303 and move with the main spindle box 11.

[0083] The rear of the third housing 1301 is equipped with a motor 1304, a clutch 1305, a limit cylinder 1307, and a limit block 1308. The motor 1304 enables the tailstock 13 to move automatically along the axial direction on the bed 14 via a gear and rack transmission. After reaching a certain limit position, the limit cylinder 1307 drives the limit block 1308 to move downward. At this time, the limit block 1308 is located at the notch of the limit rack 1309 set on the bed 14. At this time, the clutch 1305 works to disengage the motor 1304 from the end gear in the torque transmission state, and the clamping force on the tailstock is borne by the limit rack 1309.

[0084] The power component 1101 can be driven by a servo motor, a regular motor or other equipment, and a speed reducer can be configured according to the speed and torque requirements. The power component 1101 drives the first transmission shaft 1109 to rotate.

[0085] The first housing 1102 and the second housing 1201 are sealed. Under the action of the oil cooler 3, the cooling oil in the first housing 1102 and the second housing 1201 achieves circulating cooling of the internal components.
