[0048] Currently, the thermal control coating is one of the main temperature control means for spacecraft. It is a substrate material that is most widely used and has the most significant effect in spacecraft. It regulates the diffuse reflection of sunlight by spacecraft components and the absorption and radiation of energy in the infrared band, enabling the spacecraft to maintain the operating temperature of internal instruments and equipment within its maximum temperature range during the internal and external heat exchange process, ensuring the normal operation of spacecraft equipment. In order to ensure full contact between the aerospace equipment and the coating during spraying, before spraying, it is often necessary to use a corresponding grinding mechanism to fully grind the surface of the parts to remove the burrs on the outer surface of the tubular parts.

[0049] However, currently, before spraying the tubular parts, it is still necessary to use a corresponding grinding mechanism to fully grind the surface of the tubular parts. When grinding them, the position of the grinding roller cannot be fully adjusted. As a result, when grinding the surface of cylindrical parts, it is necessary to adjust the position of the surface to be processed of the parts according to the positions that the grinding roller cannot reach, which consumes more labor during grinding and cannot fully grind the outer surface of the tubular parts.

[0050] Based on this, the embodiments of this specification propose a processing solution: As Figure 1 shown, a surface grinding device for tubular devices of the present utility model, through the meshing transmission of the transmission gear 50 and the transmission tooth block 22, and by slidably arranging the sliding frame 40 on the guide ring 20, when the driving motor 52 rotates, the transmission gear 50 can drive the sliding frame 40 to rotate circumferentially along the guide ring 20, so that the grinding part 60 moves circumferentially along the guide ring 20 to circumferentially grind the outer surface of the tubular device inserted on the insertion part 30, solving the problem in the prior art that it is necessary to manually adjust the grinding surface of the tubular device or the position of the grinding mechanism, and realizing the automatic grinding of the outer surface of the tubular device.

[0051] The following will describe the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

[0052] As Figures 1 to 3As shown in the figure, a surface grinding device for a tubular device of the present utility model includes a base 10, a guide ring 20, a plug-in part 30, a sliding frame 40, a transmission gear 50, and a grinding part 60. Among them, the guide ring 20 is fixedly installed at the first end of the base 10 through a support rod 21, and a transmission tooth block 22 is arranged on the outer surface of the guide ring 20 along the circumferential direction of the guide ring 20; the plug-in part 30 is fixedly installed at the second end of the base 10 through a fixing plate 32, and an anti-slip part 31 is further arranged on the outer surface of the plug-in part 30. The plug-in part 30 and the anti-slip part 31 are used to insert into the interior of the tubular device; the sliding frame 40 is set as a cavity structure 41, and the sliding frame 40 is slidably arranged on the guide ring 20 along the circumferential direction of the guide ring 20; the transmission gear 50 is axially installed in the cavity structure 41 of the sliding frame 40 along the guide ring 20 through a transmission rod 51, and is meshed and connected with the transmission tooth block 22 arranged on the outer surface of the guide ring 20. Both ends of the transmission rod 51 are rotatably arranged on the two side walls of the cavity structure 41, and at least one end of the transmission rod 51 is connected to a driving motor 52; one end of the grinding part 60 is fixedly connected to the side wall of the sliding frame 40, and the other end extends to be vertically corresponding to the plug-in part 30 for grinding the tubular device.

[0053] Among them, the base 10 is used to provide an installation and support function.

[0054] Among them, the guide ring 20 is used to provide a slide rail and a support function, so that the sliding frame 40 can be installed on the guide ring 20 and the sliding frame 40 can rotate along the circumferential direction of the guide ring 20.

[0055] In some embodiments, the guide ring 20 can be fixed to the first end of the base 10 through the support rod 21 arranged at the bottom. At this time, the sliding frame 40 makes a reciprocating motion along the circumferential direction of the guide ring 20 under the action of the transmission gear 50 and the driving motor 52. For example, when the sliding frame 40 slides to the support rod 21 of the guide ring 20, it can move in the reverse direction.

[0056] Among them, when the sliding frame 40 makes a reciprocating motion, it is necessary for the staff to manually adjust the rotation of the tubular device to achieve grinding of the entire outer surface of the tubular device.

[0057] In some embodiments, the support rod 21 is set as an L-shaped structure. One end of the support rod 21 is connected to the inner wall of the guide ring 20, and the other end is connected to the base 10, so that the sliding frame 40 can rotate along the guide ring 20 for at least one week.

[0058] When the sliding frame 40 rotates along the guide ring 20 for at least one week, the structure of the support rod 21 can be set according to actual needs, such as being set as an n-shaped.

[0059] Among them, when one end of the support rod 21 is connected to the inner wall of the guiding ring 20, the height of the support rod 21 does not affect the insertion of the tubular element into the guiding ring 20. For example, when the support rod 21 is L-shaped, the side wall of the support rod 21 facing the guiding ring 20 is connected to the inner side wall at the lowest part of the bottom end of the guiding ring 20.

[0060] Among them, the insertion part 30 is used to insert into the interior of the tubular device to fix at least one end of the tubular device.

[0061] Among them, the insertion part 30 is arranged horizontally, and the fixing plate 32 is arranged longitudinally on the base 10.

[0062] Among them, the anti-slip part 31 is detachably arranged on the insertion part 30, such as being adhesively arranged on opposite sides of the insertion part 30.

[0063] In some of these embodiments, when the length of the insertion part 30 is sufficient, the insertion part 30 can completely fix the tubular device.

[0064] Among them, the thickness of the anti-slip part 31 can be flexibly set according to the inner diameter of the tubular device, so that at least one end of the tubular device can be fixed to the insertion part 30.

[0065] Among them, the anti-slip part 31 can be an anti-slip friction pad, and different thicknesses or layers of anti-slip friction pads can be set on the insertion part 30 according to the inner diameter of the tubular device, so as to enable the insertion and fixation of pipeline devices with different inner diameters.

[0066] For example, the anti-slip part 31 includes multiple layers of magic tapes.

[0067] Among them, the anti-slip part 31 can be wound around the insertion part 30 or can be adhesively attached to the insertion part 30.

[0068] Among them, when the pipeline device is inserted onto the anti-slip part 31 and the insertion part 30, the outer surface of the anti-slip part 31 is in close fit with the inner surface of the pipeline device.

[0069] Among them, the sliding frame 40 is used to provide installation support and a slider function, such as for installing the transmission gear 50 and the grinding part 60.

[0070] Furthermore, the sliding frame 40 is integrally arranged in a U-shaped structure.

[0071] Among them, the transmission rod 51 can be connected to the driving motor 52 through a coupling, so that the driving motor 52 can drive the transmission gear 50 to rotate through the transmission rod 51.

[0072] Among them, both ends of the transmission rod 51 are rotatably arranged on the two side walls of the cavity structure 41 through bearings.

[0073] Among them, the transmission tooth blocks 22 provided on the outer surface of the guiding ring 20 can be inserted into the cavity structure 41 to engage with the transmission gear 50.

[0074] Among them, the grinding part 60 is used to grind the outer surface of the tubular device.

[0075] Specifically, when grinding the tubular device, first paste or wind an anti-slip part 31 with an appropriate thickness on the insertion part 30, then insert one end of the tubular part onto the insertion part 30 and the anti-slip part 31, and turn on the drive motor 52. The drive motor 52 drives the transmission gear 50 to rotate through the transmission rod 51. Since the transmission gear 50 meshes with the transmission tooth blocks 22 and the sliding frame 40 is slidably connected to the guiding ring 20, the rotation of the transmission gear 50 can drive the sliding frame 40 to move circumferentially along the guiding ring 20. Furthermore, the sliding frame 40 drives the grinding part 60 to move circumferentially along the guiding ring 20 to grind the outer surface of the tubular device, so that the outer surface of the tubular device can be ground without rotating the tubular device multiple times.

[0076] In some of the embodiments, guiding grooves 23 are circumferentially formed on both side walls of the guiding ring 20; the opposite two side walls at the bottom end of the sliding frame 40 extend downward to form two opposite ear elements, and guiding blocks cooperating with the guiding grooves 23 are provided on both of the opposite ear elements. The guiding blocks are located in the guiding grooves 23 to slidably arrange the sliding frame 40 on the guiding ring 20.

[0077] Among them, the cross-section of the guiding groove 23 has the same shape and approximate size as that of the guiding block.

[0078] Furthermore, rollers are provided on the outer surface of the guiding block or the inner wall of the guiding groove 23 to facilitate the movement of the guiding block in the guiding groove 23.

[0079] Furthermore, the center of the insertion part 30 and the center of the cross-section of the guiding ring 20 are located on the same straight line, so that when the pipeline device is inserted onto the insertion part 30, the center of the pipeline device and the center of the guiding ring 20 are on the same straight line, which further facilitates the grinding part 60 to grind the outer surface of the pipeline device.

[0080] Among them, the transmission tooth blocks 22 and the support rod 21 are arranged side by side in the axial direction of the guiding ring 20 so that the support rod 21 does not encroach on the transmission tooth blocks 22.

[0081] In some of the embodiments, such as Figure 1 、 4As shown in the figure, the grinding part 60 includes a connecting plate 61, a telescopic member 62, and a grinding element 63. Among them, one end of the connecting plate 61 is fixedly connected to the side wall of the sliding frame 40, and the other end extends to correspond to the plug-in part 30 up and down. A driving hole 611 is formed in the connecting plate 61; the telescopic member 62 is arranged on the connecting plate 61, and the telescopic shaft of the telescopic member 62 passes through the driving hole 611 and extends to the outside of the connecting plate 61; the grinding element 63 is fixedly connected to the telescopic shaft of the telescopic member 62 and is used to move under the action of the telescopic member 62.

[0082] Among them, the connecting plate 61 is used to install the telescopic member 62 to support the telescopic member 62.

[0083] Among them, the connecting plate 61 can be a frame-type structure or a plate-type structure.

[0084] Among them, the telescopic member 62 can be an electric push rod.

[0085] Specifically, when grinding tubular devices with different inner diameters, the telescopic member 62 can adjust the position of the grinding element 63 so that the grinding element 63 can abut against the outer surface of the tubular device.

[0086] For example, when the outer diameter of the tubular device is small, the telescopic shaft of the telescopic member 62 can be extended outward so that the grinding element 63 is close to the outer surface of the tubular device; when the outer diameter of the tubular device is large, the telescopic shaft of the telescopic member 62 can be contracted inward so that the grinding element 63 abuts against the outer surface of the tubular device.

[0087] Furthermore, the grinding part 60 further includes a mounting bracket 64. The mounting bracket 64 is mounted on the driving hole 611 of the connecting plate 61. The mounting bracket 64 is connected to the bottom base of the telescopic member 62. The mounting bracket 64 is used to install the telescopic member 62 so that the telescopic member 62 can be fixed above the connecting plate 61.

[0088] Among them, the mounting bracket 64 can be an inverted U-shaped structure.

[0089] Furthermore, the grinding element 63 includes a driving frame 631 and a grinding roller 632. Among them, the driving frame 631 is fixedly connected to the telescopic shaft of the telescopic member 62, and the driving frame 631 has two oppositely arranged mounting parts; the grinding roller 632 is rotatably arranged between the two mounting parts, and one end of the grinding roller 632 is in transmission connection with a grinding motor. The grinding roller 632 is used to grind the tubular device when the grinding motor rotates.

[0090] In some of the embodiments, both the driving hole 611 and the telescopic member 62 are multiple to increase the supporting ability for the grinding element 63.

[0091] The working principle of the present utility model is as follows:

[0092] The thickness of the anti-slip portion 31 will be set according to the inner diameter of the tubular device, and then the tubular device will be inserted onto the anti-slip portion 31 and the insertion portion 30;

[0093] Adjust the telescopic shaft of the telescopic member 62 to extend outward or contract inward so that the grinding roller 632 is in close contact with the outer surface of the tubular device with different outer diameter sizes;

[0094] Start the drive motor 52 to drive the transmission gear 50 to rotate. Since the transmission gear 50 meshes with the transmission tooth block 22 on the guide ring 20 and the transmission gear 50 is fixedly arranged on the transmission rod transmission gear 50, at this time, the rotation of the transmission gear 50 can drive the sliding frame 40 to rotate along the guide ring 20, and the grinding roller 632 grinds the outer surface of the tubular device.

[0095] A surface grinding device for a tubular device of the present utility model can always fit the outer side of tubular aviation parts of different sizes and fully rotate and grind the outer surface of the tubular parts, reducing the labor consumption required for the staff to replace the grinding surface and also improving the grinding quality of the surface of the aviation tubular parts.

[0096] In this specification, the same or similar parts among the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments. In particular, for the product embodiments described later, since they correspond to the methods, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiments.

[0097] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
