Description

Technical Field

[0001] The present application relates to the technical field of aerospace material spray painting, and specifically to an aerospace material spray painting device. Background Art

[0002] High-temperature alloys generally have high room temperature and high temperature strength, good oxidation resistance and hot corrosion resistance, excellent creep and fatigue resistance, good organizational stability and reliability. Therefore, high-temperature alloys are not only key materials for high-temperature parts of aerospace engines, but also indispensable and important materials in industrial fields such as ships, energy, and petrochemicals. They need to be painted during production.

[0003] The prior art also proposes an improved solution for the spray painting of aerospace materials. For example, the application with publication number CN115155889A discloses a spraying robot for aerospace materials, including a base frame and a connecting plate. The connecting plate is mounted on the base frame, and a plurality of spraying mechanical arms are mounted on the connecting plate. The spraying mechanical arms are mounted on guide rails and can move along the guide rails. A No. 1 electric slide rail is mounted on both sides of the base frame, and a hot air device that can move along the No. 1 electric slide rail is mounted on the No. 1 electric slide rail, and the hot air device faces the two sides of the base frame. The present invention can effectively achieve timely drying of the paint after spraying, greatly reducing the subsequent work intensity; it is conducive to the spraying of aviation materials around, and improves the spraying efficiency. While rotating the spraying, the sliding support rod connects the placement table to the connecting plate, and it can rotate in the No. 1 annular groove and the No. 2 annular groove, which not only increases the stability, but also improves the support effect.

[0004] Although the above technical solution is conducive to spraying aviation materials around, there are still other problems in specific use. For example, when spraying aviation materials, the aviation materials need to be fixed, which makes it difficult to spray the fixed parts, affecting the subsequent use of the aviation materials.

[0005] Therefore, it is necessary to provide an aerospace material painting equipment to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] The technical solution adopted by the present application to solve its technical problems is: an aerospace material painting equipment, including a paint spraying seat, a placing plate is installed above the paint spraying seat, and the aerospace material to be painted is placed above the placing plate; an annular paint spraying tube 1 is arranged above the paint spraying seat, and an annular paint spraying tube 2 is arranged above the paint spraying seat and located on the inner side of the annular paint spraying tube 1, the length of the annular paint spraying tube 1 is greater than the length of the annular paint spraying tube 2, the annular paint spraying tube 1 and the annular paint spraying tube 2 are both connected to an external paint spraying hose, and the connecting part is rotatably arranged; a plurality of paint outlet grooves are provided on the surfaces of the annular paint spraying tube 1 and the annular paint spraying tube 2; a positioning mechanism is arranged above the paint spraying seat, and the positioning mechanism is used to fix the aerospace material to be painted, and a driving mechanism is arranged above the paint spraying seat, and the driving mechanism is used to drive the annular paint spraying tube 1, the positioning mechanism and the aerospace material to rotate.

[0008] Furthermore, the positioning mechanism includes two L-shaped support plates installed above the paint spray seat, and electric push rods are installed at the ends of the two L-shaped support plates. The telescopic end of the electric push rod is spherical in shape, and a rubber sleeve is sleeved on the outer side of the sphere.

[0009] Furthermore, the driving mechanism includes a side support plate installed on the upper end surface of the paint spray seat, two side support plates are provided, and are symmetrically arranged relative to the placement plate, the side walls of the two side support plates are rotatably installed with a rotating shaft, the outer peripheral surface of the rotating shaft is fixedly installed with a gear, and the end of the rotating shaft away from the side support plate is provided with an intermittent unit, and the intermittent unit is used to drive the annular paint spray pipe to rotate intermittently; a crown-shaped gear ring is rotatably provided above the paint spray seat, and the crown-shaped gear ring is meshingly connected with the gear, and the two L-shaped support plates are installed on the upper end surface of the crown-shaped gear ring.

[0010] Furthermore, the intermittent unit includes a cross bar rotatably arranged on the outer wall of the gear, a limiting ring is fixedly installed on the outer peripheral surface of the cross bar, and the annular paint spray tube 2 is installed on the side wall of the limiting ring through a fixing block; a limiting groove is provided on the outer surface of the limiting ring, a rubber strip is provided on the inner wall of the limiting groove, and a limiting rod is installed on the side wall of the gear.

[0011] Furthermore, a limiting torsion spring is arranged at the contact position between the cross bar and the gear, and an installation groove matched with the limiting torsion spring is arranged inside the gear; during operation, when the cross bar rotates following the limiting ring, the cross bar will simultaneously drive the limiting torsion spring on its outside to contract, and when the limiting rod is separated from the groove wall of the limiting groove, that is, the limiting ring and the annular paint spray tube are no longer rotating, the limiting torsion spring recovers under the action of elastic force, and drives the limiting ring and the annular paint spray tube to rotate in the opposite direction again, so that the shell-type aerospace material can be sprayed with paint for the second time, and the crown-shaped toothed ring below will always rotate with the gear, thereby improving the simultaneous spraying effect on the outer wall and inner wall of the shell-type aerospace material.

[0012] Furthermore, a circular groove is opened inside the gear, the outer wall of the cross bar is arranged inside the circular groove through the rotation of the circular ring, and the limiting torsion spring is arranged inside the circular groove; during operation, when the cross bar rotates, the cross bar will simultaneously drive the circular ring to rotate inside the circular groove, and under the mutual limitation of the circular ring and the circular groove, the limiting ring and the annular paint spray tube can rotate in the forward and reverse directions conveniently.

[0013] Furthermore, the placement plate is connected via an external electric pull rod, and the surface of the paint spray seat is provided with a slide groove adapted to the placement plate; because at the beginning, the shell-shaped aerospace material is placed on the placement plate, when the positioning mechanism completes the fixation of the shell-shaped aerospace material, the placement plate is driven away from the bottom of the shell-shaped aerospace material by controlling the electric pull rod to avoid contact between the upper end surface of the placement plate and the bottom end surface of the shell-shaped aerospace material, resulting in the problem that the subsequent annular paint spray tube 2 is difficult to spray paint liquid on the bottom end surface of the shell-shaped aerospace material.

[0014] Furthermore, an electric telescopic rod is installed on the upper end of the crown-shaped toothed ring, the bottom end of the L-shaped support plate contacts the telescopic end of the electric telescopic rod, and a through groove adapted to the electric telescopic rod is opened on the surface of the crown-shaped toothed ring.

[0015] Furthermore, contact one is provided on the side wall of the L-shaped support plate, contact two is installed on the surface of the crown gear ring, contact one and contact two are arranged correspondingly, and a thermal tube is installed on the surface of the crown gear ring; during operation, when the L-shaped support plate moves with the electric telescopic rod, the L-shaped support plate will simultaneously drive contact one to move, and then contact one and contact two will come into contact, at which time the external circuit is connected, and the external controller will control the hot air to blow out from the inside of the thermal tube, and along with the rotation of the crown gear ring, the hot air can accelerate the molding of the paint liquid on the outside of the shell-shaped aerospace material, and the operation is more convenient.

[0016] Furthermore, a limiting circular frame is installed above the paint spraying seat, and the bottom of the crown gear ring is rotatably arranged inside the limiting circular frame through a limiting circular rod. The limiting circular frame can facilitate the rotation of the crown gear ring itself.

[0017] The beneficial effects of the present application are as follows: the present application provides an aerospace material painting equipment, which drives two L-shaped support plates and a fixed shell-type aerospace material to rotate through a crown-shaped gear ring, and while the position of the annular paint spraying tube 2 remains unchanged, the annular paint spraying tube 2 will perform all-round paint treatment on the inner wall of the shell-type aerospace material, thereby avoiding the problem of many arc-shaped parts on the inner wall, which makes it difficult to paint completely; and the annular paint spraying tube 1, under the action of the intermittent unit, can intermittently rotate on the outer wall of the shell-type aerospace material, and cooperate with the self-rotation of the shell-type aerospace material to improve the painting effect of the shell-type aerospace material, and the painting of the shell-type aerospace material can be completed through two to three reciprocating sprayings.

[0018] The electric push rod is controlled to be away from the side wall of the shell-type aerospace material, and the electric telescopic rod is controlled to drive the L-shaped support plate and the electric push rod to move downward, so that the electric push rod does not block the shell-type aerospace material. Subsequently, with the continued rotation of the crown gear ring, the shell-type aerospace material is no longer fixed at this time, so it will not rotate. Therefore, during the subsequent painting of the annular paint spraying tube 2, the fixed part of the shell-type aerospace material by the electric push rod can be painted. This ensures that every position of the shell-type aerospace material can be painted, solving the problem of difficulty in completely painting the fixed parts in the prior art.

[0019] In addition to the above-described purposes, features and advantages, the present application also has other purposes, features and advantages. The present application will be further described in detail with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The positioning mechanism comprises two L-shaped support plates 5 installed above the spray paint seat 1, and electric push rods 6 are installed at the ends of the two L-shaped support plates 5. The telescopic end of the electric push rod 6 is spherical, and a rubber sleeve is sleeved on the outer side of the sphere; During operation, after the shell-shaped aerospace material is placed on the placement plate 2, the shell-shaped aerospace material will be located between the two electric push rods 6. The telescopic end of the electric push rod 6 is then controlled to move so that the spherical surface of the telescopic end is pressed against the surface of the shell-shaped aerospace material. In this way, the shell-shaped aerospace material can be initially fixed, thereby facilitating the subsequent painting of the shell-shaped aerospace material.

[0026] The driving mechanism includes a side support plate 7 installed on the upper end surface of the paint spraying seat 1, two side support plates 7 are provided, and are symmetrically arranged relative to the placement plate 2, the side walls of the two side support plates 7 are rotatably installed with a rotating shaft 8, the outer peripheral surface of the rotating shaft 8 is fixedly installed with a gear 9, and the end of the rotating shaft 8 away from the side support plate 7 is provided with an intermittent unit, and the intermittent unit is used to drive the annular paint spraying pipe 3 to rotate intermittently; a crown gear ring 10 is rotatably provided above the paint spraying seat 1, and the crown gear ring 10 is meshed and connected with the gear 9, and the two L-shaped support plates 5 are installed on the upper end surface of the crown gear ring 10; During operation, after the shell-shaped aerospace material is fixed by two electric push rods 6, one of the rotating shafts 8 is driven to rotate by the motor, and the rotating shaft 8 drives the gear 9 on its outer circumference to rotate, and the gear 9 will drive the crown gear ring 10 meshing with it to rotate, and the crown gear ring 10 will drive the two L-shaped support plates 5 and the fixed shell-shaped aerospace material to rotate, and while the position of the annular paint spraying tube 2 4 remains unchanged, the annular paint spraying tube 2 4 will perform all-round paint treatment on the inner wall of the shell-shaped aerospace material to avoid the problem of many arc-shaped parts on the inner wall, which makes it difficult to paint completely; and the annular paint spraying tube 1 3, under the action of the intermittent unit, can make it intermittently rotate on the outer wall of the shell-shaped aerospace material, and cooperate with the self-rotation of the shell-shaped aerospace material to improve the painting effect of the shell-shaped aerospace material, and the shell-shaped aerospace material can be painted after two or three reciprocating sprayings.

[0027] The intermittent unit includes a cross bar 11 rotatably arranged on the outer wall of the gear 9, a limiting ring 12 is fixedly installed on the outer circumference of the cross bar 11, and the annular paint spraying tube 13 is installed on the side wall of the limiting ring 12 through a fixing block; a limiting groove 121 is provided on the outer surface of the limiting ring 12, and a rubber strip 122 is provided on the inner wall of the limiting groove 121, and a limiting rod 13 is installed on the side wall of the gear 9; When working, in the initial state, the placement position of the annular paint spraying tube 3 is as follows: Figure 4 As shown, the limiting rod 13 is located inside the limiting groove 121; when the gear 9 is rotating, the gear 9 will simultaneously drive the limiting rod 13 to rotate, and because the limiting rod 13 is located inside the limiting groove 121, the limiting rod 13 will drive the limiting ring 12 to rotate under the limitation of the limiting groove 121, and the limiting ring 12 drives the annular paint spray tube 3 to rotate through the fixed block of its side wall, and slowly rotates nearly 180 degrees along the outer side of the shell-shaped aerospace material, refer to the attached Figure 5 As shown, when the limiting rod 13 and the limiting groove 121 are rotated to the position shown in the figure, the limiting rod 13 will be separated from the groove wall of the limiting groove 121, that is, the limiting ring 12 and the annular paint spray tube 3 will no longer rotate, so as to avoid the problem that the annular paint spray tube 3 continues to rotate downward and touches the crown gear ring 10 below, thereby improving the painting effect of the shell-type aerospace material. The rubber strip 122 plays a certain limiting role, which facilitates the annular paint spray tube 3 to rotate nearly one hundred and eighty degrees along the outside of the shell-type aerospace material.

[0028] A limit torsion spring 14 is arranged at the contact position between the cross bar 11 and the gear 9, and a mounting groove matched with the limit torsion spring 14 is arranged inside the gear 9; during operation, when the cross bar 11 rotates following the limit ring 12, the cross bar 11 will simultaneously drive the limit torsion spring 14 on its outer side to contract, and when the limit rod 13 is separated from the groove wall of the limit groove 121, that is, the limit ring 12 and the annular paint spraying tube 3 are no longer rotating, the limit torsion spring 14 recovers under the action of elastic force, and drives the limit ring 12 and the annular paint spraying tube 3 to rotate in the opposite direction again, so that the shell-type aerospace material can be sprayed with paint for the second time, and the crown-shaped toothed ring 10 below will always rotate following the gear 9, thereby improving the simultaneous spraying effect on the outer wall and the inner wall of the shell-type aerospace material.

[0029] A circular groove 15 is provided inside the gear 9, and the outer wall of the cross bar 11 is rotatably arranged inside the circular groove 15 through the circular ring 111, and the limiting torsion spring 14 is arranged inside the circular groove 15; during operation, when the cross bar 11 rotates, the cross bar 11 will simultaneously drive the circular ring 111 to rotate inside the circular groove 15, and under the mutual limitation of the circular ring 111 and the circular groove 15, the limiting ring 12 and the annular paint spray tube 3 can rotate forward and reversely.

[0030] The placement plate 2 is connected by an external electric pull rod, and the surface of the paint spray seat 1 is provided with a slide groove adapted to the placement plate 2; because at the beginning, the shell-shaped aerospace material is placed on the placement plate 2, when the positioning mechanism completes the fixation of the shell-shaped aerospace material, at this time, the placement plate 2 is driven away from the bottom of the shell-shaped aerospace material by controlling the electric pull rod to avoid the upper end surface of the placement plate 2 from contacting the bottom end surface of the shell-shaped aerospace material, resulting in the problem that the subsequent annular paint spray tube 3 is difficult to spray paint liquid on the bottom end surface of the shell-shaped aerospace material.

[0031] An electric telescopic rod 16 is installed at the upper end of the crown gear ring 10, and the bottom end of the L-shaped support plate 5 is in contact with the telescopic end of the electric telescopic rod 16. A through groove compatible with the electric telescopic rod 16 is opened on the surface of the crown gear ring 10. When working, after the bottom end surface of the shell-shaped aerospace material is painted, the external electric pull rod is first controlled to drive the placement plate 2 to move up, so that the placement plate 2 supports the shell-shaped aerospace material with the bottom end surface painted again, and then the electric push rod 6 is controlled to move away from the side wall of the shell-shaped aerospace material, and the electric push rod 6 is controlled to move away from the side wall of the shell-shaped aerospace material. The movable telescopic rod 16 drives the L-shaped support plate 5 and the electric push rod 6 to move downward, so that the electric push rod 6 does not block the shell-type aerospace material. Subsequently, with the continued rotation of the crown gear ring 10, the shell-type aerospace material is no longer fixed at this time, so it will not rotate. Therefore, during the subsequent painting of the annular paint spraying tube 13, the fixed part of the shell-type aerospace material by the electric push rod 6 can be painted. This ensures that every position of the shell-type aerospace material can be painted, solving the problem of difficulty in completely painting the fixed parts in the prior art.

[0032] The side wall of the L-shaped support plate 5 is provided with a contact 17, and the surface of the crown gear ring 10 is installed with a contact 2 18, and the contact 1 17 and the contact 2 18 are correspondingly arranged, and the surface of the crown gear ring 10 is installed with a thermal tube 19; during operation, when the L-shaped support plate 5 moves with the electric telescopic rod 16, the L-shaped support plate 5 will simultaneously drive the contact 1 17 to move, and then the contact 1 17 and the contact 2 18 will contact, at this time the external circuit is connected, and the external controller will control the hot air to blow out from the thermal tube 19, and with the rotation of the crown gear ring 10, the hot air can accelerate the molding of the paint liquid on the outside of the shell-shaped aerospace material, and the operation is more convenient.

[0033] A limiting circular frame 20 is installed above the paint spraying seat 1, and the bottom of the crown gear ring 10 is rotatably arranged inside the limiting circular frame 20 through a limiting circular rod. The limiting circular frame 20 is arranged to facilitate the self-rotation of the crown gear ring 10.

[0034] Working principle: Place the shell-shaped aerospace material to be painted on the placement plate 2, then fix the shell-shaped aerospace material through the positioning mechanism, then pass the paint liquid into the annular paint spraying pipe 1 3 and the annular paint spraying pipe 2 4 through the external paint spraying hose, and spray the paint to the outer wall and inner wall of the shell-shaped aerospace material through the paint outlet grooves on the surface of the annular paint spraying pipe 1 3 and the annular paint spraying pipe 2 4, respectively, to achieve simultaneous painting of the outer wall and the inner wall, and through the action of the driving mechanism, the annular paint spraying pipe 1 3 and the shell-shaped aerospace material can be rotated to improve the spraying effect of the inner and outer walls of the shell-shaped aerospace material, avoid the problem that the inner wall of the shell is difficult to be sprayed, and the operation is relatively convenient; After the shell-shaped aerospace material is fixed by the two electric push rods 6, one of the rotating shafts 8 is driven to rotate by the motor, and the rotating shaft 8 drives the gear 9 on its outer circumference to rotate, and the gear 9 drives the meshing crown gear ring 10 to rotate, and the crown gear ring 10 drives the two L-shaped support plates 5 and the fixed shell-shaped aerospace material to rotate, and the position of the annular paint spraying tube 2 4 remains unchanged, and the annular paint spraying tube 2 4 will perform all-round paint spraying on the inner wall of the shell-shaped aerospace material to avoid the problem that there are many arc-shaped parts on the inner wall, which makes it difficult to paint completely; and the annular paint spraying tube 1 3 can be made to rotate intermittently on the outer wall of the shell-shaped aerospace material under the action of the intermittent unit, and the shell-shaped aerospace material Under the rotation, the painting effect of the shell-shaped aerospace material is improved, and the shell-shaped aerospace material can be painted after two or three reciprocating sprayings; In the initial state, the placement position of the annular paint spraying tube 3 is as follows Figure 4 As shown, the limiting rod 13 is located inside the limiting groove 121; when the gear 9 is rotating, the gear 9 will simultaneously drive the limiting rod 13 to rotate, and because the limiting rod 13 is located inside the limiting groove 121, the limiting rod 13 will drive the limiting ring 12 to rotate under the limitation of the limiting groove 121, and the limiting ring 12 drives the annular paint spray tube 3 to rotate through the fixed block of its side wall, and slowly rotates nearly 180 degrees along the outer side of the shell-shaped aerospace material, refer to the attached Figure 5As shown, when the limiting rod 13 and the limiting groove 121 are rotated to the position shown in the figure, the limiting rod 13 will be separated from the groove wall of the limiting groove 121, that is, the limiting ring 12 and the annular paint spraying tube 3 will no longer rotate, so that the problem of the annular paint spraying tube 3 continuing to rotate downward and touching the crown gear ring 10 below can be avoided, thereby improving the painting effect of the shell-type aerospace material. The rubber strip 122 plays a certain limiting role, which facilitates the annular paint spraying tube 3 to rotate nearly 180 degrees along the outer side of the shell-type aerospace material; when the cross bar 11 follows the limiting ring 12 When rotating, the cross bar 11 will simultaneously drive the limiting torsion spring 14 on its outer side to contract. When the limiting rod 13 is separated from the groove wall of the limiting groove 121, that is, the limiting ring 12 and the annular paint spraying tube 3 are no longer rotating, the limiting torsion spring 14 is restored under the action of elastic force, and drives the limiting ring 12 and the annular paint spraying tube 3 to rotate in the opposite direction again, so that the shell-type aerospace material can be sprayed with paint for the second time, and the crown gear ring 10 below will always rotate with the gear 9, thereby improving the simultaneous spraying effect on the outer wall and the inner wall of the shell-type aerospace material; After the bottom end surface of the shell-shaped aerospace material is painted, the external electric pull rod is first controlled to drive the placement plate 2 to move upward, so that the placement plate 2 can support the shell-shaped aerospace material with the bottom end surface painted again, and then the electric push rod 6 is controlled to move away from the side wall of the shell-shaped aerospace material, and the electric telescopic rod 16 is controlled to drive the L-shaped support plate 5 and the electric push rod 6 to move downward, so that the electric push rod 6 does not block the shell-shaped aerospace material, and then the crown gear ring 10 continues to rotate, and the shell-shaped aerospace material is no longer fixed at this time, so it will not rotate, so it can be painted by the subsequent annular paint spraying tube 3. At the beginning, the electric push rod 6 is used to spray paint the fixed parts of the shell-type aerospace material, which ensures that every position of the shell-type aerospace material can be painted, solving the problem of fixed parts being difficult to completely paint in the prior art; when the L-shaped support plate 5 moves with the electric telescopic rod 16, the L-shaped support plate 5 will simultaneously drive the contact 1 17 to move, and then the contact 1 17 and the contact 2 18 will come into contact. At this time, the external circuit is connected, and the external controller will control the hot air to blow out from the inside of the thermal tube 19, and with the rotation of the crown gear ring 10, the hot air can accelerate the molding of the paint liquid on the outside of the shell-type aerospace material, and the operation is more convenient.
