Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a support device for a cylindrical shell. Background Art

[0002] At present, the spraying of cylinders and cylindrical shells with small diameters and small lengths is usually completed by vertical spraying in one pass, while the spraying of large-diameter and long cylindrical shells is completed by horizontal placement and spraying in two passes. Because one side needs to be in contact with the shell support when placed horizontally and cannot be sprayed, it is necessary to wait for drying after spraying one side and then change to the other side for spraying. This spraying method will form an interface defect, where the coating thickness is uneven at the interface of the two sprays, resulting in poor coating bonding force and poor adhesion.

[0003] In view of the problem of uneven coating thickness at the interface during the spraying process of large cylindrical shells in the prior art, there is currently no effective solution. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides a support device for a cylindrical shell. By horizontally placing the cylinder on this device, connecting the two ends of the cylinder through a connecting piece, and setting the edge of the connecting piece on the top roller group of the support roller frame assembly, the cylinder can be rotated while spraying to ensure 360° overall spraying of the shell, so as to solve the problem of uneven coating thickness at the interface during the split-surface spraying process in the prior art.

[0005] To achieve the above object, the utility model provides a support device for a cylindrical shell, including: a connecting piece, with the connecting piece connected to both ends of the shell to be processed, and the cross-section of the connecting piece being circular; a support roller frame assembly, the support roller frame assembly being correspondingly arranged with the connecting piece, the support roller frame assembly including a bracket and a roller group movably connected to the top of the bracket, and the roller group being in contact with the outer edge of the connecting piece.

[0006] Further optionally, the bracket includes: vertical plates, connecting plates and first connecting columns; two vertical plates form a support plate group, the two vertical plates in the support plate group are arranged face to face and are connected through the first connecting columns; the two support plate groups are connected through the connecting plates; and a roller group is movably connected to the top of the support plate group.

[0007] Further optionally, an adsorbent is provided at the bottom of the connecting plate.

[0008] Further optionally, the adsorbent is a magnet or a suction cup.

[0009] Further optionally, the roller set includes: side plates, roller shafts, rollers and second connecting columns; two side plates are arranged face to face and connected by the second connecting columns; the rollers are movably connected between the two side plates through the roller shafts, and the outer surface of the rollers protrudes from the top of the side plates.

[0010] Further optionally, the rotating shaft sequentially passes through the centers of the two side plates arranged face to face, and the two ends are respectively movably connected to the brackets.

[0011] Further optionally, two rollers are arranged between the two side plates; the two rollers are symmetrically arranged with the central axis of the rotating shaft as the axis of symmetry.

[0012] Further optionally, side retaining wheels are provided at the tops of the side plates.

[0013] Further optionally, the rollers are made of rubber.

[0014] Further optionally, the connecting member has different diameters at both ends. The end with the smaller diameter is connected to the end of the shell to be processed, and the outer edge of the end with the larger diameter contacts the top of the support roller frame assembly.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] To solve the problem that in the prior art, it is difficult to spray a cylindrical shell in one time during the spraying process, resulting in uneven coating at the spraying interface, the present invention provides a support device for a cylindrical shell. Figure 1 It is a structural schematic diagram of the support device for a cylindrical shell provided by the embodiment of the present invention during assembly, as Figure 1 shown. The device includes: a connecting piece 2, with connecting pieces 2 connected to both ends of the housing 1 to be processed. The cross-section of the connecting piece 2 is circular; a supporting roller frame assembly 3, the supporting roller frame assembly 3 is correspondingly arranged with the connecting piece 2, and the supporting roller frame assembly 3 includes a roller group 301 movably connected to the top of the bracket 302, and the roller group 301 contacts the outer edge of the connecting piece 2.

[0024] As Figure 1 shown, the device includes a connecting piece 2 and a supporting roller frame assembly 3, where there are two connecting pieces 2 with the same structure. As Figure 2 shown, the two connecting pieces 2 are respectively installed on the two end faces of the cylindrical shell through bolts.

[0025] Since there may be various types of cylindrical shells to be sprayed during actual processing, the connecting piece 2 with corresponding dimensions can be set according to the diameters of different types of cylindrical shells.

[0026] As Figure 1 shown, there are also two identical supporting roller frame assemblies 3 on the left and right. The two supporting roller frame assemblies 3 respectively support the two connecting pieces 2. Specifically, as Figure 3As shown, the support roller frame assembly 3 includes a bracket 302 and a roller group 301. The bottom of the bracket 302 is stably arranged on the workbench, and the top is movably connected with the roller group 301. The roller group 301 can rotate within a certain range relative to the bracket 302 to adapt to the support requirements of different models of shells and shells under different conditions, ensuring stable support for the connecting piece 2.

[0027] When spraying operations are carried out, the staff can perform spraying operations from the side of the shell, and while spraying, rotate the shell to the unsprayed area, thus completing the one-time spraying of the shell.

[0028] As an alternative implementation, as Figure 3 shown, the bracket 302 includes: a vertical plate 3021, a connecting plate 3022 and a first connecting column 3023; the two vertical plates 3021 form a support plate group, and the two vertical plates 3021 in the support plate group are arranged face to face and connected by the first connecting column 3023; the two support plate groups are connected by the connecting plate 3022; the top of the support plate group is movably connected with the roller group 301.

[0029] As Figure 3 shown, the bracket 302 includes a vertical plate 3021, a connecting plate 3022 and a first connecting column 3023. The two vertical plates 3021 are arranged parallel to each other face to face and connected by the first connecting column 3023. There is a certain space between the two vertical plates 3021, and the roller group 301 is arranged at the top position between the two vertical plates 3021.

[0030] Each bracket 302 includes two groups of vertical plates 3021, and the two groups of vertical plates 3021 are connected by the connecting plate 3022. In this way, the roller groups 301 of the two groups of vertical plates 3021 can jointly provide stable support for the connecting piece 2 on one side.

[0031] The two support roller frame assemblies 3 have a total of four roller groups 301, and the four roller groups 301 jointly provide stable support for the shell.

[0032] As an alternative implementation, an adsorbent 3024 is provided at the bottom of the connecting plate 3022.

[0033] An adsorbent 3024 is provided at the bottom of the connecting plate 3022, and the support roller frame assembly 3 can be quickly removed from the workbench or quickly installed on the workbench through the adsorbent 3024. And for shells of different sizes, the distance between the two support roller frame assemblies 3 can be adjusted adaptively.

[0034] As an alternative implementation, the adsorbent 3024 is a magnet or a suction cup.

[0035] If the workbench is made of metal, an electromagnet can be selected as the adsorbent, and it can be quickly disassembled when not in use, without occupying the workbench.

[0036] In addition, if the workbench is not made of metal, a suction cup can be used as the suction attachment, and the purpose of quick disassembly can also be achieved.

[0037] As an alternative embodiment, Figure 4 is a schematic structural diagram of the roller set provided by the embodiment of the present invention. As Figure 4 shown, the roller set 301 includes: side plates 3011, roller shafts 3013, rollers 3012 and second connecting columns 3014; two side plates 3011 are arranged face to face and connected by second connecting columns 3014; the rollers 3012 are movably connected between the two side plates 3011 through roller shafts 3013, and the outer surface of the rollers 3012 protrudes from the top of the side plates 3011.

[0038] As Figure 4 shown, the roller set 301 includes two side plates 3011 arranged parallel to each other face to face. Combining Figure 3 it can be known that the outer surface of one of the side plates contacts the inner surface of a vertical plate of the bracket, and the outer surface of the other side plate contacts the inner surface of the other vertical plate of the bracket. The two side plates 3011 are connected by second connecting columns 3014.

[0039] The rollers 3012 are fixed between the two side plates 3011 through axially arranged roller shafts 3013 and can rotate around the roller shafts 3013. The top of the rollers 3012 protrudes from the top of the side plates 3011, and the connecting member 2 contacts the rollers 3012, so as to ensure that when the control housing rotates, the connecting member 2 can rotate relative to the workbench under the action of the rollers 3012.

[0040] As an alternative embodiment, the rotating shaft 3015 sequentially passes through the centers of the two side plates 3011 arranged face to face, and the two ends are respectively movably connected to the bracket 302.

[0041] The rotating shaft 3015 sequentially passes through the two side plates 3011, and the two ends are respectively connected to the two vertical plates 3021 of the bracket 302, so that the whole roller set 301 can rotate around the rotating shaft 3015.

[0042] As an alternative embodiment, two rollers 3012 are provided between the two side plates 3011; the two rollers 3012 are symmetrically arranged with respect to the central axis of the rotating shaft 3015.

[0043] Two rollers 3012 are provided between the two side plates 3011, and the two rollers 3012 are symmetrically arranged with respect to the central axis of the rotating shaft 3015, ensuring the balance of the roller set 301 when not stressed, and can jointly complete stable support for the supporting connecting member 2, and can adapt to the support requirements of different sizes of the housing.

[0044] In addition, since the roller group 301 is installed on the vertical plate 3021 through the rotating shaft 3015, and each roller group 301 has two rollers 3012, according to the upper open design of the support roller frame assembly 3, by replacing the connecting pieces 2 of different sizes, the device can also be adapted to cylindrical shells with larger different diameters.

[0045] As an alternative embodiment, a side retaining wheel 3016 is provided at the top of the side plate 3011.

[0046] As Figure 4 shown, a side retaining wheel 3016 is provided at the top of the side plate 3011. In this embodiment, a baffle is provided at the center of the top of one of the vertical plates 3021 of each roller group 301, and side retaining wheels 3016 are symmetrically provided on both sides of the baffle. The side retaining wheel 3016 can ensure that the cylindrical shell will not roll off the support roller frame assembly 3 even if it leans against one side. At the same time, since the side retaining wheel 3016 is rotatable, the spraying work can be continuously completed.

[0047] As Figure 3 shown, when each support roller frame assembly 3 has two roller groups 301, the side retaining wheels 3016 in the two roller groups 301 are provided on the vertical plates 3021 on different sides.

[0048] Of course, side retaining wheels 3016 can also be provided at the top of each side plate 3011.

[0049] As an alternative embodiment, the roller 3012 is made of rubber.

[0050] The roller 3012 being made of rubber can not only increase the friction with the support member, but also ensure that the connecting piece 2 will not be worn, so as to avoid the problem of unbalanced shell caused by different center of gravity of the connecting pieces 2 on both sides.

[0051] As an alternative embodiment, the connecting piece 2 has different diameters at both ends. The small-diameter end is connected to the end of the shell 1 to be processed, and the outer edge of the large-diameter end contacts the top of the support roller frame assembly 3.

[0052] As Figure 2 shown, the connecting piece 2 has different diameters at both ends, generally in a trumpet shape. The diameter of the small port is the same as the end face diameter of the shell, and the diameter of the large port is larger than the end face diameter of the shell, and has a certain thickness, and can rotate stably on the roller group 301. Since the other end of the connecting piece 2 has a larger diameter, the shell can be placed randomly whether it is in the original state, the grinding state or the state where the paint is not dry, without causing damage such as scratches, bumps or paint adhesion to the outer surface of the shell.

[0053] The above technical solution has the following beneficial effects: it improves the spraying integrity, can ensure the adhesion of the paint, and realizes the ability to serve underwater for a long time; it can improve the production efficiency to a certain extent, shortening the time required for at least two sprayings to one spraying time, and reducing the time occupied by the production platform for paint drying and air drying; due to the setting of the connecting piece, the advantages of convenient random placement and hoisting of the shell are realized.

[0054] The specific implementation manners of the above utility model further elaborate on the purpose, technical solution and beneficial effects of the utility model. It should be understood that the above content is only the specific implementation manner of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
