Description

Technical Field

[0001] The invention relates to the field of intelligent manufacturing technology, and in particular to a cockpit painting clamping suspension device. Background Art

[0002] Intelligent manufacturing is a human-machine integrated intelligent system composed of intelligent machines and human experts. It can perform intelligent activities such as analysis, reasoning, judgment, conception and decision-making during the manufacturing process. Through the cooperation between people and intelligent machines, the mental labor of human experts in the manufacturing process can be expanded, extended and partially replaced. With the advancement of science and technology, the cockpit painting process is also constantly developing in the direction of intelligent manufacturing.

[0003] When the cockpit is suspended for painting, a steel rope and a hook are often used to suspend the cockpit, and then the painting operation is carried out. For example, a Chinese patent (Announcement No.: CN106622770A) discloses a clamping suspension device for cockpit painting, including a base, a pillar, a flange cross bar, a concave flange sleeve, a nut fixing block, a thin steel wire rope, a barb, a gear plate, a rotating gear plate, a clamping block, a round hole, and a threaded hole. The base is provided with a hole for fixing. The pillar is welded to the base and reinforced with a reinforcing rib. The flange cross bar is arranged between the two pillars. The concave flange sleeve is sleeved on the flange cross bar, and the nut fixing block is arranged thereon. One end of the thin steel wire rope is placed in the nut fixing block and fixed by a bolt through the threaded hole, and the other end is provided with the barb. The round hole and the threaded hole are vertically connected structures. The gear plate, the rotating gear plate and the clamping block are arranged on one side of the pillar.

[0004] In the above technical solution, the painting process is convenient, and the painting of the inside and outside is carried out at the same time. It is easy to use, solves the process of double-sided painting at the same time, saves the time of the process flow and reduces the production cost, but it still has the following defects:

[0005] 1) When the cockpit is being painted, excess paint tends to flow onto the ground, which not only pollutes the environment and is not environmentally friendly, but also makes it impossible to recycle the paint, increasing costs;

[0006] 2) After the cockpit is suspended, it cannot be rotated. When painting multiple surfaces, workers need to move back and forth to paint, which reduces the painting efficiency and is time-consuming and labor-intensive;

[0007] 3) If a paint recovery tank is provided under the suspension device, the top surface of the paint recovery tank must be in an open shape to facilitate the entry of the paint. However, the open paint recovery tank is prone to dust entry, which increases the subsequent paint purification steps and affects the recycling effect.

[0008] 4) After the cockpit is suspended by the suspension device, if the cockpit is rotated, it is difficult to ensure the stability of the cockpit only by the suspension structure in the vertical direction.

[0009] Based on this, a cockpit painting clamping suspension device is proposed to solve the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1In this embodiment, a cockpit painting clamping suspension device includes a paint recovery tank 1 for recovering excess paint liquid, a rotating mechanism 2 is provided on the paint recovery tank 1, a bracket 3 is provided on the rotating mechanism 2, the rotating mechanism 2 is used to drive the bracket 3 and the cockpit to rotate and adjust, the bracket 3 is provided with a fixing mechanism 4 for assisting in fixing the cockpit, a dustproof mechanism 5 for dustproofing is provided inside the paint recovery tank 1, a plurality of electric hoists 6 are fixed to the top end of the bracket 3, and an L-shaped hook 7 for hanging the cockpit is fixed to the bottom end of the electric hoist 6.

[0034] It should be noted that the L-shaped hook 7 and the cockpit are raised and lowered by the electric hoist 6, and the cockpit is suspended, and then the cockpit is auxiliary fixed by the fixing mechanism 4. During the painting process, the rotating mechanism 2 drives the cockpit to rotate, and the excess paint liquid can be recovered and filtered by the paint liquid recovery tank 1. When the suspension device is not used, the opening of the paint liquid recovery tank 1 can be blocked by the dustproof mechanism 5 to prevent dust from entering the paint liquid recovery tank 1, thereby reducing the subsequent paint liquid recovery and purification process.

[0035] See also Figure 1-2 In order to facilitate painting, the rotating mechanism 2 in this embodiment includes a rotating motor 201 fixed to the inner bottom surface of the paint liquid recovery tank 1, and the rotating mechanism 2 also includes a rotating rod 202 rotatably connected to the center of the inner bottom surface of the paint liquid recovery tank 1. A transmission component 203 is provided between the outer surface of the rotating rod 202 and the output shaft of the rotating motor 201. A support plate 204 rotatably connected to the top surface of the paint liquid recovery tank 1 is fixed to the top of the rotating rod 202, and a guide ring 205 is fixed to the bottom surface of the support plate 204. A filter screen 206 is fixed to the inner wall of the paint liquid recovery tank 1, and the filter screen 206 is located between the transmission component 203 and the dustproof mechanism 5. A collecting groove 207 corresponding to the filter screen 206 is fixed to the outer surface of the paint liquid recovery tank 1, and a plurality of discharge holes connected to the collecting groove 207 are opened on the outer surface of the paint liquid recovery tank 1.

[0036] Among them, the transmission component 203 includes a driving gear fixed on the output shaft of the rotating motor 201, and the transmission component 203 also includes a driven gear fixed to the bottom of the outer surface of the rotating rod 202, and the driven gear is meshed with the driving wheel. The output shaft of the rotating motor 201 drives the driving gear to rotate, and cooperates with the driven gear, so that the rotating rod 202 can drive the support plate 204 to rotate and adjust.

[0037] At the same time, the support plate 204 includes an outer ring, multiple inner rings, multiple support rods and a disc. The outer ring, multiple inner rings, multiple support rods and the disc are arranged in sequence from the outside to the inside, and the outer ring, multiple inner rings and the disc are connected and fixed by multiple support rods. The guide ring 205 is fixed to the bottom surface of the outer ring. The setting of the support plate 204 can provide support while facilitating the paint liquid to enter the paint liquid recovery tank 1.

[0038] Moreover, an annular groove is provided at the top of the paint liquid recovery tank 1 , and the guide ring 205 is rotatably connected in the annular groove, thereby guiding the rotation. The cross-section of the filter screen 206 is trapezoidal, which is convenient for collecting impurities on the filter screen 206 .

[0039] It can be understood that a liquid guiding tube for guiding the paint liquid is fixed at the bottom of the outer surface of the paint liquid recovery tank 1, a boss is fixed on the bottom surface of the inner cavity of the paint liquid recovery tank 1, and the rotating mechanism 2 is arranged on the boss. The setting of the boss can facilitate the flow of the paint liquid.

[0040] The rotating mechanism 2 in this embodiment can rotate through the output shaft of the rotating motor 201, and cooperate with the transmission assembly 203 to rotate the support plate 204 and drive the cockpit to rotate, thereby facilitating the painting operation of the cockpit. In addition, the excess paint liquid can be recovered through the paint liquid recovery tank 1 and filtered by the filter screen 206.

[0041] See also Figure 3-5 In order to achieve auxiliary fixation of the cockpit, the fixing mechanism 4 in this embodiment includes a slider 401 slidably connected to the left and right ends of the outer surface of the bracket 3, the front end of the slider 401 is threadedly connected with a fixing bolt 402, the opposite ends of the two sliders 401 are fixed with a connecting head 403, the end of the connecting head 403 away from the slider 401 is slidably connected with a universal ball 404, the end of the universal ball 404 away from the connecting head 403 is fixed with a connecting rod 405, the outer surface of the connecting rod 405 is slidably connected with a slide plate 406, the left and right ends of the bottom surface of the slide plate 406 are fixed with guide rods 407, the bottom end of the connecting rod 405 is fixed with a fixing plate 408 slidably connected to the outer surfaces of the two guide rods 407, the outer surface of the connecting rod 405 is sleeved with a spring 409, the bottom ends of the two guide rods 407 are fixed with a connecting plate 410, and the bottom end of the connecting plate 410 is fixed with a hook 411.

[0042] In addition, the two ends of the spring 409 are respectively in contact with the lower surface of the slide plate 406 and the upper surface of the fixed plate 408. A semicircular groove is provided inside the connecting head 403 for the universal ball 404 to move, and a cross groove is provided at the end of the connecting head 403 away from the slider 401 for the connecting rod 405 to move. The universal ball 404 can perform multiple adjustments in the semicircular groove. The setting of the cross groove makes it convenient for the connecting rod 405 and the universal ball 404 to be adjusted and moved according to the position of the holes on the cockpit.

[0043] The fixing mechanism 4 in this embodiment moves by pulling the hook 411, so that the slide plate 406 squeezes the spring 409 to move, and the hook 411 is hung in the hole on the cockpit, so that the cockpit can be pulled by the hook 411 and auxiliary fixed.

[0044] See also Figure 6In order to achieve dust prevention of the paint liquid recovery tank 1, the dust prevention mechanism 5 in this embodiment includes a fixed ring 501 fixed to the inner wall of the paint liquid recovery tank 1, the left end of the inner side of the fixed ring 501 is rotatably connected to a plurality of evenly distributed rotating shafts 502, the right end of the rotating shaft 502 penetrates to the outside of the fixed ring 501 and the paint liquid recovery tank 1, the outer surface of the rotating shaft 502 is fixed with a baffle 503 located on the inner side of the fixed ring 501, and the right end of the rotating shaft 502 is fixed with a worm gear 504. The dust prevention mechanism 5 also includes mounting plates 505 fixed to the front and rear ends of the paint liquid recovery tank 1, one end of one of the mounting plates 505 away from the paint liquid recovery tank 1 is fixed with an adjusting motor 506, the output shaft of the adjusting motor 506 is fixed with a worm 507 meshing with a plurality of worm gears 504, and the end of the worm 507 away from the adjusting motor 506 is rotatably connected to another mounting plate 505.

[0045] The dustproof mechanism 5 in this embodiment, when the suspension device is not used, can drive the worm 507 to rotate by adjusting the output shaft of the motor 506, so that the multiple worm gears 504 drive the baffle 503 to rotate to a vertical state and block the position of the paint liquid recovery tank 1 to prevent dust from entering.

[0046] It is understandable that the dust on the surface of the baffle 503 after it is closed can be removed by an external dust removal device, which is a relatively conventional technical content in the prior art.

[0047] It should be noted that the control method of the present invention is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0048] The working principle of the above embodiment is:

[0049] The cockpit is lifted and lowered by the electric hoist 6, and then hung in the hole on the cockpit by the L-shaped hook 7, so as to suspend the cockpit. After that, the position of the hook 411 is adjusted according to the position of the hole on the cockpit and the size of the cockpit by pulling the hook 411. The movement of the hook 411 can cause deformation by squeezing the spring 409 through the connecting plate 410 and the slide plate 406. The spring 409 provides auxiliary pulling force to the cockpit, thereby realizing auxiliary fixation of the cockpit, and then the painting operation is carried out. During the painting process, the output shaft of the rotating motor 201 drives the driving gear to rotate, and cooperates with the driven gear to realize that the rotating rod 202 drives the support plate 204 to rotate, and the guide ring 205 rotates in the annular groove to adjust the position of the cockpit. There is no need for the staff to walk back and forth to perform the painting operation. In addition, excess paint liquid generated by spraying can enter the paint liquid recovery tank 1 through the support plate 204, then be filtered through the filter screen 206, and then be discharged through the liquid guide tube. Larger impurities on the filter screen 206 can be collected by the collection tank 207. Finally, when the suspension device is not in use, the worm 507 can be driven to rotate by adjusting the output shaft of the motor 506. The worm 507 is meshed with the worm gear 504, so that multiple worm gears 504 drive the rotating shaft 502 to rotate, so that multiple baffles 503 are in a horizontal state and block the opening of the paint liquid recovery tank 1 to prevent dust from entering the paint liquid recovery tank 1. The dust on the baffle 503 can be cleaned by an external dust removal device. When the device needs to be used, the baffle 503 can be rotated to a vertical state.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
