Description

Technical Field

[0001] The utility model relates to the technical field of large-scale parts spraying devices, in particular to a large-scale parts spraying device. Background Art

[0002] In industrial production, surface treatment of large parts is an important link, especially for large parts that need to be sprayed. Spraying can not only provide a protective layer to prevent parts from corrosion and wear, but also provide a beautiful surface effect. However, the size and weight of large parts make their double-sided spraying operations complicated and difficult.

[0003] Traditional spraying operations usually require large parts to be placed on a support table installed, and the visible surfaces are sprayed using a gantry-type spraying structure. For example, Chinese patent announcement number "CN110665709A" discloses a large component spraying device, which mainly includes a conveyor positioning system, an external axis movement system, a robotic arm control system and a paint spraying system; the robotic arm control system is installed on the external axis movement system, and the paint spraying system is installed on the robotic arm control system; the conveyor positioning system pulls the product to be painted to the middle of the external axis movement system.

[0004] Since the spraying of parts has two sides, when dealing with large parts, due to their size and weight, it is difficult for traditional spraying mechanisms to turn over the parts after spraying them, which causes certain inconveniences when spraying parts on both sides. Based on this, in order to further optimize the convenience of existing spraying devices in dealing with double-sided spraying, we propose a large parts spraying device. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 An embodiment of the utility model discloses a large-scale parts spraying device, which includes a gantry 1, and a displacement mechanism 2 is arranged above the gantry 1. Specifically, the displacement mechanism 2 includes an X-direction driving mechanism, a Y-direction driving mechanism and a Z-direction driving mechanism. A nozzle 3 is arranged on the displacement mechanism 2. The nozzle 3 described in this embodiment is installed on the Z-direction driving mechanism. The specific displacement method and principle have been disclosed in the prior art and will not be repeated here.

[0023] Among them, the lower inner side of the gantry 1 is slidably connected to a frame 5 through a guide rail 4, that is, in this embodiment, a walking wheel cooperating with the guide rail 4 is rotatably connected to the bottom of the frame 5. Preferably, the walking wheel described in this embodiment can be driven by a reduction motor to realize automatic controlled walking of the entire frame 5. A support plate 6 is rotatably connected to the frame 5, and a driving member 7 for driving the support plate 6 to flip is also provided on the frame 5. A lifting device 8 is also fixed at the tail end of the gantry 1. The lifting device 8 described in this embodiment is configured as a winch, and its cable end is connected to a hook for lifting. This structure is a prior art and will not be elaborated here.

[0024] In some embodiments, the driving member 7 in the utility model is configured as a cylinder, and two cylinders are provided and are pinned to both sides of the frame 5 respectively, and the axial ends of the cylinders are rotatably connected to the support plate 6, that is, in this embodiment, after spraying of one side of the part is completed, the entire support plate 6 can be driven by two cylinders to flip. Preferably, the maximum flipping angle of the support plate 6 in this embodiment is 80° to avoid the part tipping over due to excessive flipping angle. After flipping, the part can be lifted by the above-mentioned lifting equipment, rotated one circle after lifting and placed on the support plate 6 again to complete the flipping of the part. Thereafter, the support plate 6 is reset and moved to the bottom of the nozzle 3 to realize processing on the other side of the part.

[0025] Furthermore, the support plate 6 in this embodiment is of an L-shaped structure, and a support column 61 is fixed at the upper end of the support plate 6. A flexible member 62 is fixedly installed on the top of the support column 61. The flexible member 62 is configured as a rubber pad, which is used to achieve flexible contact with the part to avoid the problem of damage to the outer wall of the part caused by hard contact.

[0026] In some embodiments, a counterweight assembly 9 is further provided on the side of the frame 5 in the utility model, and the counterweight assembly 9 is arranged on the front side of the flipping direction of the support plate 6. When the support plate 6 is flipped, considering the heavy weight of large parts, the center of gravity of the entire frame 5 will be shifted. Therefore, the counterweight assembly 9 provided in this embodiment is used to achieve counterweighting to prevent the entire frame 5 from tipping over.

[0027] Specifically, the counterweight assembly 9 in this embodiment includes two first connecting rods 91 pinned to the frame 5, a second connecting rod 92 is pinned to the free end of the first connecting rod 91, a cross bar 93 is pinned between the ends of the two second connecting rods 92, wherein a spring 94 is fixedly connected between the cross bar 93 and the frame 5, and a fixing part 95 is provided on the cross bar 93.

[0028] On the basis of the above-mentioned embodiment, the fixing member 95 in this embodiment is an adjusting foot threadedly connected to the cross bar 93, and two adjusting feet are arranged on the cross bar 93 at intervals. In specific operation, when the frame 5 moves outward to the bottom of the lifting device 8, the cross bar 93 is pulled outward. During this process, the first connecting rod 91 and the second connecting rod 92 are rotated and unfolded at the same time to form a certain force length. Thereafter, the adjusting foot on the cross bar 93 is rotated to make it contact with the ground to bear force, and the configuration adjustment can be completed, so that the force arm in the flipping direction of the support plate 6 increases to avoid the occurrence of flipping.

[0029] On the basis of the above-mentioned embodiment, in the present embodiment, a positioning glass bead 96 is provided at the end of the first connecting rod 91, and a positioning hole 97 which is clamped with the telescopic end of the positioning glass bead 96 is provided at the end of the second connecting rod 92. The structure of the positioning glass bead 96 is a prior art and will not be elaborated herein. In the present embodiment, the telescopic end of the positioning glass bead 96 is clamped into the positioning hole 97 of the second connecting rod 92 so as to fix the unfolded positions of the first connecting rod 91 and the second connecting rod 92 when unfolding them, so as to avoid the problem that the tension of the spring 94 pulls the cross bar 93 to move during the fixing process. Of course, when storing, the first connecting rod 91 and the second connecting rod 92 can be folded and stored by only pressing the telescopic end of the positioning glass bead 96 to disengage it from the positioning hole 97.

[0030] In summary, the utility model aims to simplify the double-sided spraying process of large parts. The core of the solution is that a reversible support plate 6 is installed on the frame 5. This design cleverly overcomes the difficulties of double-sided processing of large parts in traditional spraying operations. During the spraying process, once one side of the large part is sprayed, the support plate 6 can be started to smoothly flip the part to the appropriate angle. Then, the lifting device 8 intervenes and cooperates with the support plate 6 to accurately lift and rotate the part to ensure that each side of the part can be evenly sprayed. After the rotation, the part is stably placed on the support plate 6 again. After the support plate 6 is reset, the flipping operation is successfully completed, and preparations are made for the spraying operation on the other side. The device design not only simplifies the operation process and improves the spraying efficiency, but also reduces the safety risks in the operation, providing an efficient and convenient solution for the double-sided processing of large parts.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
