[0032] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0034] See also Figure 1-Figure 5 As shown, the utility model is a polishing device for aerospace accessories, comprising a polishing table 1, a polishing frame 2 is arranged on the top of the polishing table 1, a polishing assembly 3 is arranged on the outer surface of the polishing frame 2, a transverse guide rail 4 is arranged on the upper surface of the polishing table 1, a transverse slide seat 5 is slidably connected to the outer surface of the transverse guide rail 4, a support block 6 is fixedly connected to one side of the transverse slide seat 5, a driving assembly 7 is rotatably connected to one side of the support block 6, and a first gear 8 is arranged on the other side of the support block 6;

[0035] One end of the driving assembly 7 passes through the supporting block 6 and is fixedly connected to one side of the first gear 8. The top of the transverse sliding seat 5 is fixedly connected to a supporting plate 9. One side of the supporting plate 9 is rotatably connected to a second gear 10. The first gear 8 and the second gear 10 are meshed with each other. The outer surface of the second gear 10 is fixedly connected to a first supporting assembly 11, and the outer surface of the transverse guide rail 4 is slidably connected to a second supporting assembly 12.

[0036] When in use, one end of the pipe to be polished is sleeved on one end of the first support component 11, and the other end is sleeved on the outside of the end of the second support component 12. At this time, the second support component 12 is restricted by the pipe and cannot slide outside the transverse guide rail 4. When the pipe needs to be polished, the driving component 7 is started to rotate around the circumference. The rotation of the driving component 7 drives the first gear 8 fixed at one end to rotate. At the same time, the driving component 7 rotates around the circumference to push the first gear 8 to drive the support block 6 to move, thereby driving the transverse slide seat 5 to slide outside the transverse guide rail 4. At this time, the first gear 8 continues to rotate. The second gear 10 meshing with it is driven to rotate. The second gear 10 is driven to rotate and at the same time drives the first first support assembly 11 in front of it to rotate slowly. Since the pipe is supported between the first first support assembly 11 and the second support assembly 12, the rotation of the first first support assembly 11 drives the pipe to rotate on its own. At this time, the horizontal slide seat 5 continues to move toward the grinding assembly 3, and the grinding assembly 3 is started. The horizontal slide seat 5 continues to slide and displace while pushing the pipe toward the grinding assembly until the surface of the pipe continues to displace and rotates close to the outside of the grinding assembly 3 to contact with its outer surface for grinding.

[0037] The utility model fixes the first supporting assembly 11 and the second gear 10 respectively. When it is necessary to grind the pipe fitting, the first gear 8 can be driven to rotate by starting the driving assembly 7, while driving the horizontal sliding seat 5 fixed to the bottom of the supporting block 6 to slide, and the first gear 8 simultaneously drives the second gear 10 to rotate to drive the first supporting assembly 11 to rotate, thereby driving the pipe fitting supported by its end to self-rotate. Therefore, when the grinding assembly 3 is started, the driving assembly 7 indirectly drives the horizontal sliding seat 5 and the first supporting assembly 11 to automatically approach the grinding position of the grinding assembly 3, and at the same time drives the pipe fitting to self-rotate and contact with the grinding assembly 3 for grinding, so as to realize automatic pushing of the material for grinding after the pipe fitting is fixed, and at the same time make it self-rotate and change the surface evenly for grinding, thereby preventing the situation of low grinding efficiency and operation risks in manual fixed feeding grinding, and improving the grinding quality and efficiency of accessories.

[0038] In one embodiment, for the above-mentioned first motor 301, the grinding assembly 3 includes a first motor 301, the output end of the first motor 301 is fixedly connected to a rotating shaft, the inner wall of the grinding frame 2 is provided with a grinding wheel 302, and the rotating shaft passes through the inner wall of the grinding frame 2 and is fixedly connected to the grinding wheel 302.

[0039] The first motor 301 is located on the outer side of the grinding frame 2, which is obliquely above the first motor 301. The grinding frame 2 supports the first motor 301 at a certain height. By starting the first motor 301, the rotating shaft is driven to rotate, thereby driving the grinding wheel 302 to rotate at a high speed. When the pipe fitting approaches, its surface contacts the center position of the outer side of the grinding wheel 302 to cause friction, and the pipe fitting is ground and polished.

[0040] By fixing the first motor 301 on the outside of the grinding frame 2 and parallel to the grinding wheel 302, the grinding wheel 302 can be located above the first support assembly 11 and the second support assembly 12, so as to provide displacement space for pipe fixing or self-feeding grinding, and to grind and polish pipe accessories of different lengths.

[0041] In one embodiment, for the above-mentioned rotating plate 701, the driving assembly 7 includes a rotating plate 701, a second motor 702 is fixedly installed on the top of the grinding table 1, a second rotating shaft 703 is fixedly installed on the output end of the second motor 702, one end of the second rotating shaft 703 is fixedly connected to a guide plate 704, and one end of the guide plate 704 is rotatably connected to the rotating plate 701 and fits with one side thereof.

[0042] One side of the connecting plate 701 is fixed to the first gear 8. When the second motor 702 is started to drive the second rotating shaft 703 to rotate, the second rotating shaft 703 drives the guide plate 704 to rotate, and then drives the connecting plate 701 to rotate. After the connecting plate 701 rotates, it drives the first gear 8 on the other side to rotate. The guide plate 704 and the connecting plate 701 move in a circle, pushing the first gear 8 and the horizontal sliding seat 5 fixed to it to slide and displace, thereby driving the first first support assembly 11 to synchronously displace on the outside of the horizontal guide rail 4. The second gear 10 is driven to rotate by the first gear 8, driving the first first support assembly 11 in front and the pipe fitting fixed at the end to rotate.

[0043] The second motor 702 drives the second rotating shaft 703 to rotate, driving the guide plate 704 to rotate and cooperate with the connecting plate 701 to drive the second gear 10 to rotate and push the first support assembly 11 to slide and move closer to the grinding wheel 302, so that the displacement and rotation are synchronized through the same driving source, and the pipe is quickly fed and polished.

[0044] In one embodiment, for the above-mentioned cross support rod 1102, the first support assembly 11 comprises a cross support rod 1102, and one end of the cross support rod 1102 is fixedly connected to a first locking sleeve 1103;

[0045] The second support assembly 12 includes a guide slider 1202, the top of which is fixedly connected to a support frame 1203, one end of the support frame 1203 is rotatably connected to a second locking sleeve 1204, and the first locking sleeve 1103 and the second locking sleeve 1204 are symmetrically arranged above the transverse guide rail 4.

[0046] The cross support rod 1102 supports the first locking sleeve 1103 above the cross guide rail 4, and the first locking sleeve 1103 is symmetrically supported on the end of the support frame 1203. When the pipe fitting needs to be fixed, the first locking sleeve 1103 is passed through the inner hole at one end of the pipe fitting. At this time, the sliding guide slider 1202 adjusts its position outside the cross guide rail 4 according to the length of the pipe fitting until the second locking sleeve 1204 extends to the inside of the inner hole at the other end of the pipe fitting and is squeezed and locked with the inside. When the second gear 10 is driven to rotate by the first gear 8, the cross support rod 1102 in front of it is driven to rotate, thereby driving the first locking sleeve 1103 and the pipe fitting in front to rotate. The second locking sleeve 1204 is restricted by the inside of the pipe fitting and drives it to rotate synchronously. When the pipe fitting moves, it pushes the guide slider 1202 to slide and move on the outside of the cross guide rail 4 at the same time.

[0047] By fixing the first locking sleeve 1103 and the cross support rod 1102 symmetrically with the second locking sleeve 1204, and the guide sliding block 1202 can drive the support frame 1203 and the second locking sleeve 1204 to slide, the polishing pipe fittings can be fixed and locked at both ends, and the distance between the second locking sleeve 1204 and the first locking sleeve 1103 can be adjusted according to the length of the pipe fitting, so as to fix and support polishing pipe fittings of different lengths.

[0048] In one embodiment, for the above-mentioned first locking sleeve 1103, the material of the first locking sleeve 1103 and the second locking sleeve 1204 are both elastic rubber, and the inside of the first locking sleeve 1103 and the second locking sleeve 1204 are both provided with an inner shrinkage hole 1104, the top of the horizontal sliding seat 5 is fixedly connected with a support sleeve rod 1105, and the horizontal support rod 1102 passes through the inside of the support sleeve rod 1105.

[0049] The first locking sleeve 1103 and the second locking sleeve 1204 are both made of elastic rubber material. When the pipe fitting needs to be fixed, the first locking sleeve 1103 and the second locking sleeve 1204 are squeezed to make their ends shrink inwardly of the shrinkage hole 1104 until they are completely clamped in the inner hole of the pipe fitting to lock it. The support sleeve rod 1105 is supported on the outside of the cross support rod 1102 and its bottom is fixed on the top of the cross sliding seat 5 to support the middle section of the cross support rod 1102.

[0050] Through the cooperation of the first locking sleeve 1103 and the second locking sleeve 1204 with a certain elasticity, the two ends of the pipe fitting can be quickly locked and fixed, so that it can be suspended above the horizontal guide rail 4, and the support sleeve rod 1105 plays an auxiliary supporting role for the middle section of the horizontal support rod 1102, thereby improving the stability of the end of the first locking sleeve 1103. When the pipe fitting is polished, the first locking sleeve 1103 and the second locking sleeve 1204 can be squeezed and twisted again to remove the pipe fitting, making it more convenient and flexible when fixing and disassembling.

[0051] In one embodiment, for the above-mentioned square connecting groove 13 , a square connecting groove 13 is opened on the upper surface of the grinding table 1 , and the square connecting groove 13 is located directly below the guide plate 704 .

[0052] The square connecting groove 13 is located below the guide plate 704. Since the guide plate 704 continuously moves in a circle, the square connecting groove 13 can provide a connection and proximity between the movement trajectory of the guide plate 704 and the connecting plate 701 to prevent friction damage between them and the grinding table 1.

[0053] In one embodiment, for the above-mentioned lifting gear plate 14, the transverse guide rail 4 is U-shaped, and the lifting gear plates 14 are fixedly installed at both ends of the transverse guide rail 4, the outer surface of the lifting gear plate 14 is meshed with a rotating gear 15, and one side of the rotating gear 15 is fixedly connected to a rocker 16.

[0054] The lifting tooth plate 14 is located outside the two ends of the transverse guide rail 4. The rotating gear 15 can be driven to rotate by rotating the rocker 16. When the rotating gear 15 rotates, it drives the lifting tooth plate 14 on one side to move so that the transverse guide rail 4 can be lifted and lowered.

[0055] By arranging lifting tooth plates 14 on the outer sides of both ends of the transverse guide rail 4, when the thickness of the pipe fittings is inconsistent and cannot contact the grinding surface of the grinding wheel 302, the lifting tooth plate 14 is driven to move by rotating the gear 15, thereby adjusting the height of the transverse guide rail 4 extending above the grinding table 1, and then the support height of the first support assembly 11 and the second support assembly 12 can be adjusted, respectively providing suitable support positions for pipe fittings of different thicknesses so that they can contact and grind the grinding surface at the center of the outer side of the grinding wheel 302.

[0056] In one embodiment, for the gear slot 17 , the rocker arm 16 extends to the outside of the grinding table 1 , and the gear slot 17 is opened inside the grinding table 1 .

[0057] The rocker 16 extends to one side of the grinding table 1, and the gear slot 17 is located inside the grinding table 1. When the cross guide rail 4 needs to be raised or lowered, the operator can rotate the rocker 16 on the outside of the grinding table 1 to drive the rotating gear 15 to rotate and drive the lifting gear plate 14 to lift or lower, which is convenient for the operator to operate. The gear slot 17 provides a built-in space for the rotating gear 15.

[0058] In one embodiment, for the above-mentioned embedded groove 18, the top of the grinding table 1 is provided with an embedded groove 18, the inner wall of the embedded groove 18 is slidably connected with a bottom slider 19, and the top of the bottom slider 19 is fixedly connected to the bottom of the grinding machine frame 2.

[0059] The embedded groove 18 is located directly below the bottom of the grinding frame 2, providing a bottom slider 19 that can drive the bottom of the grinding frame 2 to slide on the inner wall of the embedded groove 18, driving the grinding frame 2 to move forward and backward to shorten or increase the distance between it and the transverse guide rail 4.

[0060] By setting the bottom slider 19 slidably connected to the inside of the embedded groove 18, the grinding machine frame 2 can be driven to perform longitudinal displacement, so as to adjust the distance between it and the cross guide rail 4 according to the different thicknesses of the pipes, and synchronously adjust the lateral distance between the grinding wheel 302 and the cross guide rail 4, so as to adjust the distance difference of the polishing contact surface for the pipes of different thicknesses.

[0061] In one embodiment, for the above-mentioned side fixing plate 20, the two side surfaces of the grinding machine frame 2 are fixedly connected with the side fixing plate 20, and a fixed side plate 21 is provided at the bottom of the side fixing plate 20, and one end of the fixed side plate 21 extends to the upper surface of the grinding table 1, and the tops of the two ends of the fixed side plate 21 are threadedly connected with fixed bolt rods 22.

[0062] One end of the fixed side plate 21 is connected to the bottom of the side fixing plate 20 in an upward tilted manner. When the grinding machine frame 2 needs to be moved, the fixing bolt rod 22 above the top of the side fixing plate 20 and the other end of the fixed side plate 21 is rotated at the same time to make the fixed side plate 21 loose and rotatable, and the grinding machine frame 2 can be moved.

[0063] By threading the loose fixed side plate 21 and the side fixing plate 20 through the fixing bolt rod 22, the side of the grinding frame 2 can be restricted. When the fixed side plate 21 is in a loose state, the grinding frame 2 can be displaced forward and backward while driving the fixed side plate 21 to rotate. The fixed side plate 21 and the side fixing plate 20 are always coaxially arranged, so that the grinding frame 2 can be fixed and loosened, so that its supporting position can be flexibly adjusted.

[0064] In addition, in a specific application, after the grinding machine frame 2 is displaced, the fixing bolt rod 22 is rotated again to lock the fixing side plate 21 with the side fixing plate, and the position of the grinding machine frame 2 is locked.

[0065] In summary, with the aid of the above technical solution of the utility model, a transverse guide rail 4 is arranged at the lower side of the grinding wheel 302, and the two ends of the pipe fitting are locked and fixed by the elastic first locking sleeve 1103 and the second locking sleeve 1204. When the pipe fitting needs to be polished and ground, the second motor 702 is started to drive the guide plate 704 to rotate, and then the connecting plate 701 is driven to drive the first gear 8 to rotate, and then the connecting plate 701 is continuously rotated and the second gear 10 is driven to rotate under the cooperation of the first gear 8. At the same time, the first gear 8 is pushed to drive the transverse sliding seat 5 to slide on the outside of the transverse guide rail 4, and the first motor 301 is started to drive the grinding wheel 302 to rotate at a high speed. At this time, the transverse sliding seat 5 drives the upper pipe fitting to continuously move toward the grinding wheel. The wheel 302 approaches and self-rotates to grind, so that the grinding wheel 302 evenly grinds and polishes its surface, and through the setting of the lifting tooth plate 14, when it is necessary to polish the pipe fittings of different thicknesses, the lifting tooth plate 14 is driven to lift and lower by rotating the rocker 16 to drive the rotating gear 15 to rotate and drive the lifting tooth plate 14 to lift and lower, and adjust the support height of the cross guide rail 4 and the corresponding first first support assembly 11 and second support assembly 12 to adapt to pipe fittings of different thicknesses, and the longitudinal position of the grinding frame 2 is adjusted by the bottom slider 19 sliding on the inner wall of the embedded groove 18, and the longitudinal spacing is synchronously adjusted in coordination with the liftable cross guide rail 4 to meet the processing conditions of pipe fittings of different thicknesses, and polish pipe fittings of different thicknesses and lengths respectively.

[0066] Through the above technical scheme, 1. By fixing the first supporting assembly 11 and the second gear 10 respectively, when it is necessary to grind the pipe fitting, by starting the driving assembly 7, the first gear 8 can be driven to rotate and at the same time drive the horizontal sliding seat 5 fixed to the bottom of the supporting block 6 to slide, and the first gear 8 simultaneously drives the second gear 10 to rotate and drive the first supporting assembly 11 to rotate, thereby driving the pipe fitting supported at its end to self-rotate. Therefore, when the grinding assembly 3 is started, the driving assembly 7 indirectly drives the horizontal sliding seat 5 and the first supporting assembly 11 to automatically approach the grinding position of the grinding assembly 3, and at the same time drives the pipe fitting to self-rotate and contact with the grinding assembly 3 for grinding, so as to achieve the fixing of the pipe fitting. 1.
