Description

TECHNICAL FIELD

[0001] The utility model relates to engine cylinder body surface paint spraying technical field especially relates to a kind of engine cylinder body protective paint layer uniform paint spraying device. BACKGROUND

[0002] Engine cylinder body is the core component of engine, and the quality of its surface protective paint layer directly affects the performance, service life and corrosion resistance of engine. Coating uniform and dense protective paint layer on the surface of cylinder body can not only improve the wear resistance and corrosion resistance of cylinder body, but also effectively reduce the energy loss during engine operation. However, the traditional paint spraying method has many shortcomings, which limits the further improvement of the quality of cylinder body protective paint layer. At present, the common cylinder body surface paint spraying methods mainly include manual paint spraying and traditional mechanical paint spraying equipment. Although manual paint spraying is flexible, it is easily affected by factors such as worker's operation experience, paint spraying distance and angle, resulting in uneven thickness of protective paint layer, and even causing paint spraying dead angle. At the same time, manual paint spraying is low in efficiency and difficult to meet the needs of industrial mass production. The traditional mechanical paint spraying equipment realizes paint spraying by fixed spray head, but due to the limited number of spray heads, the paint spraying range is relatively narrow, the equipment adjustment process is complex, and for the surface of cylinder body with complex structure, paint spraying may not be in place.

It is convenient and fast to operate, and at the same time, the speed reducer motor is started, the carrier plate is slowly rotated, drives the cylinder head to rotate, can avoid the operator to hold the spray gun to rotate around the cylinder head, can save the physical strength of operator.

[0004] Although the prior art 1 can help the operator to save physical strength through a series of settings, and try to keep the standardization and standardization of operation as much as possible, so that the operator can maintain a relatively stable state when performing tasks, but the essence of manual operation still cannot completely avoid some inherent problems, such as shaking and non-standard operation habits in the operation process. The existence of these problems often leads to uneven distribution of thickness in the process of spraying or paint spraying, and further affects the quality of the final product, so that the product cannot reach the ideal quality standard.

[0029] Embodiment 1

[0030] Referring to Figure 1 The engine cylinder body protective paint layer uniform paint spraying device provided by the embodiment of the utility model can effectively solve the problem of uneven paint spraying in the prior art. In addition, the paint spraying device of the embodiment can also solve the problem of lack of good support for the paint spraying device when adapting to a cylinder body of a larger size.

[0031] Referring to Figure 1 and Figure 2 In the embodiment, the engine cylinder body 400 protective paint layer uniform paint spraying device comprises a lifting mechanism 100 and a mounting rack 200, and the mounting rack 200 is arranged above the lifting mechanism 100. The mounting rack 200 can be lifted or lowered correspondingly with the lifting operation of the lifting mechanism 100. The main function of the lifting mechanism 100 is to realize all-around paint spraying of the cylinder body, so as to avoid uneven phenomena in the paint spraying process. The mounting rack 200 is used for mounting various components of the paint spraying mechanism 300, so that the paint spraying mechanism 300 can move with the movement of the cylinder body, thereby realizing uniform paint spraying operation of the cylinder body.

[0032] Referring to Figure 2 and Figure 5 On the mounting rack 200, a paint spraying mechanism 300 and a ring-shaped paint spraying pipeline are arranged, and the ring-shaped paint spraying pipeline 310 is arranged above the paint spraying mechanism 300. By using the ring-shaped paint spraying pipeline for paint spraying operation, it can be ensured that the entire circumference range of the cylinder body is sprayed at the same time, so that the paint spraying operation is more uniform.

[0033] The ring-shaped paint spraying pipeline can have various shapes, including but not limited to a circular ring, an elliptical ring, a rectangular ring, a triangular ring, etc. The arrangement of these shapes can meet different types of paint spraying requirements and provide customized solutions for different working environments.

[0034] Taking the circular ring-shaped paint spraying pipeline 310 as an example, its equidistantly distributed nozzles make it particularly suitable for cylindrical or nearly circular cylinder bodies. The pipeline structure of the circular ring-shaped paint spraying pipeline 310 is simpler, and the paint spraying pressure distribution is more uniform. This type of paint spraying pipeline is particularly suitable for circular or nearly circular cylinder bodies, such as common engine cylinder bodies 400 or liquid storage tanks, etc. When a high consistency of paint spraying thickness is required, the circular ring-shaped paint spraying pipeline 310 can provide the best paint spraying effect and ensure uniform coverage. In addition, the maintenance of the equipment and the cleaning of the pipeline are relatively convenient.

[0035] The elliptical annular paint spray pipe 310 offers high adaptability, making it particularly suitable for cylinders with elliptical or near-elliptical cross-sections. This pipe design allows for variable-width painting, enabling adjustments to the paint width to cover different cylinder cross-sectional dimensions. It is especially suitable for special containers or irregularly shaped cylinders with elliptical cross-sections, such as elliptical cylinders in fluid power equipment. When a portion of the cylinder has a unique curved surface that is difficult to completely cover, the paint spray area can be adapted to the complex shape, thereby reducing repainting and improving the painting efficiency of cylinders with asymmetrical cross-sections.

[0036] The rectangular annular spray nozzle 310 offers a wide coverage area, making it ideal for rectangular or flat cylinders. Directional spraying allows for targeted spraying angles to be set for corner areas, achieving efficient coverage of large flat surfaces. This type of nozzle is particularly suitable for containers with rectangular or square cross-sections, such as flat cylinder surfaces, large enclosures, and straight structures in specialized equipment. The clean and simple spray path design contributes to improved efficiency, especially for cylinders requiring focused coverage of straight edges.

[0037] The triangular annular paint spray pipe 310 is highly adaptable to special shapes, making it particularly suitable for cylinders with triangular or irregular cross-sections. Its compact structure saves paint material when painting small cylinders. This pipe is especially suitable for containers with triangular or acute-angled polygonal cross-sections, such as compact special industrial containers. It is ideal for precise painting of complex edges or corners, saving paint material and making it perfect for small, high-precision painting needs. Furthermore, the spray angle can be individually set to accommodate the special requirements of complex edges.

[0038] Furthermore, the annular spray painting pipe 310 is provided with at least one inlet 321 and several evenly distributed outlets 322. The inlet 321 is connected to each outlet 322, ensuring that the paint material can be fed and discharged simultaneously, thereby improving the efficiency of the spray painting operation. Each outlet 322 is equipped with a nozzle 323. The nozzles 323 allow the paint material to be sprayed evenly and powerfully onto the surface of the cylinder. In addition, by using high-pressure spray nozzles 323, the spraying force is greater, thereby enhancing the adhesion of the paint material and ensuring the durability and reliability of the paint effect.

[0039] During use, the operator only needs to drive the annular paint spray pipe 310 to move along the vertical direction of the engine block 400 to easily achieve uniform paint spraying on the surface of the engine block 400. This process does not require any movement of the engine block 400 itself, greatly simplifying the operation process and making the entire painting operation very convenient and efficient.

[0040] Referring to Figure 1 In this embodiment, the bottom of the lifting mechanism 100 is provided with a mounting seat 110 to facilitate the installation of the engine cylinder block 400. The engine cylinder block 400 can be fixed on the mounting seat 110 with the aid of a clamp or directly using its own weight. When using the direct installation method, the weight of the cylinder itself is sufficient to ensure that it remains stable and immobile during the painting process; when using a clamp for installation, the clamping force of the clamp will ensure that the cylinder also remains stable and does not move during the painting process.

[0041] In addition, the annular painting pipeline 310 is arranged to completely wrap the engine cylinder block 400, forming an annular space with an adapted inner diameter. This arrangement allows the painting pipeline to move up and down synchronously with the lifting mechanism 100, thereby achieving complete coverage of the engine cylinder block 400 in the vertical direction. To accommodate different sizes of cylinder block outer diameters, the inner diameter of the annular painting pipeline 310 is designed to be replaceable or adjustable, ensuring uniformity and consistency of the painting effect. With this arrangement, the moving painting pipeline can easily cover the vertical direction of the cylinder block, thereby achieving efficient and uniform painting work.

[0042] Referring to Figure 2 In this embodiment, the lifting mechanism 100 includes a stable base, and a first lifting frame 120 and a second lifting frame 130 arranged on both sides of the base, respectively. The tops of the two lifting frames are fixedly connected together by a connecting plate 140, ensuring the stability of the overall structure. In particular, the first lifting frame 120 and the second lifting frame 130 are each equipped with a pair of oppositely arranged support rods 121, and the two pairs of support rods 121 form a lifting space 122 therebetween, providing the necessary space for the operation of the lifting mechanism 100. In addition, the inner side of each pair of support rods 121 is provided with a slide rail 123, which provides important guidance for the smooth sliding of the lifting mechanism 100.

[0043] Referring to Figure 3 and Figure 4In the lifting mechanism 100, the two sides of the mounting frame 200 are respectively provided with a first sliding part 210 and a second sliding part 220 which are in sliding connection with the first lifting frame 120 and the second lifting frame 130. The design of these sliding parts enables the lifting mechanism 100 to flexibly perform vertical lifting movement. Specifically, the first sliding part 210 is provided with a first pulley 211 and a second pulley 212, and the two pulleys are respectively matched with the slide rails 123 of a pair of support rods 121 on the first lifting frame 120; similarly, the second sliding part 220 is provided with a third pulley 221 and a fourth pulley 222, and the pulleys are also respectively matched with the slide rails 123 of a pair of support rods 121 on the second lifting frame 130. Through such a design, when the mounting frame 200 is driven to move, the first sliding part 210 and the second sliding part 220 can drive the first pulley 211 and the second pulley 212, the third pulley 221 and the fourth pulley 222 arranged thereon to smoothly slide along the slide rails 123 on the first lifting frame 120 and the second lifting frame 130, thereby realizing stable lifting of the lifting mechanism 100.

[0044] Please refer to Figure 2 In this embodiment, the retractable lifting mechanism 100 comprises a cylinder 141 which is used to drive the mounting frame 200 to perform lifting operation. In addition, the lifting mechanism 100 is also provided with a pulley which is installed at the end of the piston rod 142 of the cylinder 141. On the pulley, an lifting belt 143 is arranged, that is, a belt connected with the mounting frame 200. The two ends of the lifting belt 143 are respectively connected with the mounting frame 200 and the bottom of the cylinder 141.

[0045] The retractable cylinder 141 drives the piston rod 142 to perform lifting operation, so that the lifting belt 143 based on the pulley presents a state of contraction or release. This change of state drives the lifting operation of the mounting frame 200. When the piston rod 142 of the cylinder 141 is retracted inward, the belt is released, and the mounting frame 200 is displaced downward due to the action of gravity; on the contrary, when the piston rod 142 of the cylinder 141 extends outward, the belt is contracted and tightened, the contracted mounting frame 200 is subjected to external force and moves upward based on the sliding connection with the first lifting frame 120 and the second lifting frame 130. Through such upward or downward movement, uniform painting operation is realized for the cylinder 141.

[0046] Please refer to Figure 2 In this embodiment, the mounting frame 200 is composed of two main parts, namely a first mounting plate 231 and a second mounting plate 232; the two mounting plates are designed in an "L" type structure so that they can be connected and supported at a specific angle.

[0047] The paint spraying mechanism 300 is arranged at the outer side of the lifting mechanism 100; in addition, a through hole 233 for mounting the annular paint spraying pipeline 310 is arranged on the second mounting plate 232. The through hole 233 can be circular or rectangular, which can adapt to paint spraying pipelines of different shapes and sizes, thereby ensuring that the paint spraying mechanism 300 can be flexibly applied to various working environments.

[0048] In the arrangement of the paint spraying mechanism 300, the redundancy of the supply pipeline 324 needs to be considered so that the supply pipeline 324 can adapt to the change of the paint spraying range. The paint spraying mechanism 300 is arranged at the outer side of the lifting mechanism 100, which contains multiple key components such as a paint tank, an air compressor and the supply pipeline 324. The supply pipeline 324 is designed to have a large redundancy, which makes the supply pipeline 324 can be flexibly stretched to the highest or lowest point of the lifting mechanism 100, thereby ensuring that the paint spraying operation can be carried out throughout the range of the lifting mechanism 100, achieving comprehensive coverage, improving the operation efficiency and quality.

[0049] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
