Description

Technical Field

[0001] This utility model relates to the technical field of cylinder block production, and in particular to a mounting structure for cylinder block powder spraying. Background Technology

[0002] As a crucial automotive component, the engine block is complex in structure and shape, with numerous machined end faces and holes, uneven wall thickness, and high precision requirements, making it a typical box-type machined part. The coating process for engine block castings involves spraying a coating onto the surface. The coating requires a clean surface free of oxide scale, rust, sand, dust, and contaminants. Currently, powder coating of engine blocks requires a fixture to feed the block into the powder coating system or equipment. However, current powder coating fixtures for engine blocks may have the following drawbacks:

[0003] First, there are too few hanging positions, resulting in low powder spraying efficiency;

[0004] Secondly, the original hanging point of the hanger was in contact with the product surface, which prevented the powder from adhering to the product surface. Because the hanger and the product were very close, the hanger and the product competed for powder, resulting in uneven powder spraying on the product surface and thin coating in some areas, which increased the product defect rate and increased the turnaround time.

[0005] Third, the original hanging fixtures had a simple structure and could not meet the needs of varying product specifications and changes in product structure.

[0006] Fourth, the limited number of available hanging spaces requires more manpower, which can easily lead to staff fatigue and waste of human and material resources, thus increasing company costs.

[0007] In view of this, the inventor has designed a mounting structure for cylinder powder spraying, which leads to this invention. Utility Model Content

There are two first crossbars 20, which are located on both sides of the main support column 10. There are two secondary support columns 30, which are respectively arranged on the two first crossbars 20, that is, the two secondary support columns 30 are located on both sides of the main support column 10. There are several sets of hook structures 40, which are arranged between the main support column 10 and the secondary support columns 30. The two first crossbars 20 are arranged perpendicular to the main support column 10. The hook structure 40 includes a first hook 41 arranged on both sides of the main support column 10 and a second hook 42 arranged on the inner side of the two secondary support columns 30. The first hook 41 and the second hook 42 hang the cylinder 001. The hanger structure of this utility model enables multiple cylinders 001 to be powder-coated by setting multiple hook structures 40, thereby improving the powder coating efficiency of the cylinders 001. At the same time, the first hook 41 and the second hook 42 can hold the cylinders 001, thus reducing the contact area between the hanger structure and the cylinders 001 and improving the yield of powder coating.

[0040] Please refer to the details. Figure 1 , 2 The number of hook structures 40 on both sides of the main support column 10 is the same. In this utility model, a total of six sets of hook structures 40 are provided, which can spray powder on six cylinders 001 at one time. Three sets of hook structures 40 are provided on both sides of the main support column 10.

[0041] Please refer to the details. Figure 1 , 2The first crossbar is used to install the secondary support column 30, which can be directly fixed to the first crossbar 20. A second crossbar 50 is set on the main support column 10 and above the first crossbar 20 to facilitate the removal of the entire hanger structure. One end of the second crossbar 50 can be directly welded to the main support column 10. At the same time, a hook part 11 is provided at the upper end of the main support column 10 so that after the entire hanger structure is hung in the designated position, the cylinder 001 can be powder sprayed.

[0042] Please refer to the details. Figure 1 , 2 The main support column 10, secondary support column 30, first crossbar 20, and second crossbar 50 can be made of square tubing, although the second crossbar 50 can be made of round tubing for easy handling of the entire hanging structure. The others are made of square tubing for easy connection. The secondary support column 30 is fixedly mounted on the first crossbar 20. Specifically, it can be fixed by welding or bolts. For example, the secondary support column 30 can be placed below the first crossbar 20, and bolts can be threaded through the first crossbar 20 to connect it to the secondary support column 30. Alternatively, the secondary support column 30 can be fixed to the first crossbar 20 by a bushing 31. The bushing 31 is welded to the first crossbar 20, and the secondary support column 30 is welded below the bushing 31.

[0043] Please refer to the details. Figure 1 , 2 The first hook 41 and the second hook 42 have the same structure 40, both including a support base 43 set on the side wall of the main support column 10 / secondary support column 30 and a column 44 set above the support base 43; the cylinder body 001 has a hole 002 that can be fitted onto the column 44.

[0044] Please refer to the details. Figure 3-5Another embodiment of this utility model is as follows: Since the spacing between the holes 002 of different cylinder block 001 specifications is different, only the position of the secondary support column 30 needs to be adjusted. That is, the secondary support column 30 is slidably connected to the first crossbar 20, so as to facilitate powder spraying for cylinder blocks 001 of different specifications and improve the applicability of the hanger structure. Specifically, a bushing 31 is provided above the secondary support column 30 for slidably connecting with the first crossbar 20. The bushing 31 is sleeved on the first crossbar 20 and slidably connected to the first crossbar 20. The secondary support column 30 is fixed to the lower part of the bushing 31 by welding. Further, it is also provided that: it includes an adjustment device 60 for adjusting the position of the secondary support column 30. Through the adjustment device 60, the distance between the secondary support column 30 and the main support column 10 changes to adapt to cylinder blocks 001 of different specifications. The adjusting device 60 includes an adjusting rod 61 disposed on the side wall of the main support column 10, and a limiting member 62 disposed on the adjusting rod 61 for limiting the position of the secondary support column 30. The secondary support column 30 is slidably connected to the adjusting rod 61. The limiting member 62 is located outside the secondary support column 30 and is threadedly connected to the adjusting rod 61. The end of the adjusting rod 61 furthest from the main support column 10 has an external thread, and the limiting member 62 can be a bolt, thus limiting the position of the secondary support column 30 through the screw connection.

[0045] Please refer to the details. Figure 3-5 A further configuration includes: the adjusting device 60 also includes a spring 63 sleeved on the adjusting rod 61 and located between the main support column 10 and the secondary support column 30. Under the action of the spring 63, the secondary support column 30 is always pressed against the limiting member 62 to facilitate the rapid insertion of the cylinder body 001. A shim 64 is also provided between the limiting member 62 and the secondary support column 30.

[0046] The usage of this utility model's hanging structure is as follows:

[0047] The main support column 10 of the hanger structure is placed and fixed on the assembly platform. Two auxiliary support columns 30 are inserted from both sides of the main support column 10. Next, the product (i.e., cylinder 001) is hung horizontally on the hanger structure. The hanger is manually lifted and placed in the upper hanging area. The start button is pressed, and the product is sequentially fed into the powder spraying area. The hanger structure effectively improves product qualification rate, increases production efficiency, enhances employee motivation, and improves overall profitability, depending on the product specifications. This utility model's hanger structure provides a high-efficiency, high-quality production mode for qualified products, reducing employee workload, increasing employee motivation, and saving production costs.

[0048] In summary, the hanging fixture structure of this utility model, by setting multiple hook structures, enables powder spraying onto multiple cylinders, thereby improving the powder spraying efficiency of the cylinders. Simultaneously, the first and second hooks can hold the cylinders, thus reducing the contact area between the hanging fixture structure and the cylinders, improving the yield rate of powder spraying. Furthermore, the distance between the secondary support column and the main support column of this utility model is adjustable, i.e., the distance between the first and second hooks is adjustable, to accommodate powder spraying of cylinders of different specifications. Therefore, the improved hanging fixture structure of this utility model is structurally stable, increases the adjustment distance, allows for easy handling of products of different specifications, and enhances applicability; it increases the number of hanging points, improving production efficiency and reducing labor costs; it increases the distance between the hanging fixture and the product, reducing the defect rate and saving production costs; and it reduces operational intensity and increases employee motivation.
