Technical Field

[0001] The utility model relates to the field of auxiliary components for thin-walled part processing, and particularly relates to a support device for thin-walled part processing. Background Technique

[0002] There are a large number of thin-walled cylindrical parts with relatively large sizes in major equipment in the aerospace field. During the process of machining the outer surface, it is required to be clamped and fixed by internal support highly reliably to avoid loosening and deformation.

[0003] Specifically in actual production, the commonly used internal support clamping methods mainly include integral rigid support of the inner tire and filling type internal support, etc. Currently, the commonly used support method is integral rigid support of the inner tire. However, in the specific design of the existing integral rigid support device of the inner tire, since its outer surface (i.e., the support surface) of the inner tire is usually designed to be in the same state as the inner surface of the part (i.e., the surface to be supported), this causes certain limitations in the use of the integral rigid support device of the inner tire and cannot reliably support thin-walled cylindrical parts with different cylinder diameter specifications. Content of the Utility Model

[0004] The purpose of the utility model is to provide a support device for thin-walled part processing to solve the above problems. It is provided with a plurality of inner support driving components and an internal support component evenly distributed in the circumferential direction. In this way, the buffer support block of the internal support component can be driven by the inner support driving component to move, so as to tightly support the thin-walled workpiece body from the inside. The details are described below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A support device for thin-walled part processing provided by the utility model includes a base and a thin-walled workpiece body.

[0008] Safety limit components are installed at positions where all the top parts of the inner support driving components are far from each other, so as to limit the internal support component from accidentally moving after tightly supporting the thin-walled workpiece body through the safety limit component.

[0009] Preferably, each of the inner support driving assemblies includes a fixed seat, a cylinder body, and a moving seat. The fixed seats are fixedly installed at both sides and front and rear positions of the top surface of the base. A plurality of the fixed seats are evenly distributed in the circumferential direction. The fixed seats at both sides are arranged horizontally, and the fixed seats at the front and rear positions are arranged longitudinally. A chute is formed on the top surface of each fixed seat along its own direction, and the ends of all the chutes close to each other are open. The ends of all the chutes far from each other are fixedly closed with sealing plates. The outer end faces of all the sealing plates far from each other are fixedly provided with the cylinder bodies along the direction of the corresponding chutes. The inner ends of the push rods of the cylinder bodies all pass through the corresponding sealing plates in a sliding fit manner and enter the chutes. The inner ends of the push rods are fixedly installed with the moving seats through connecting sleeves, and the moving seats are horizontally slidably matched with the corresponding chutes. The inner support assemblies are installed at the positions where the tops of all the moving seats are close to each other, and the safety limit assemblies are installed at the positions where the tops of all the moving seats are far from each other.

[0010] Preferably, each of the chutes is one of a dovetail groove or an I-shaped groove, and the top surface of each moving seat is not lower than the top of the corresponding chute.

[0011] Preferably, each of the inner support assemblies includes a vertical plate and a mounting plate. The vertical plates are fixedly erected at the positions where the tops of all the moving seats are close to each other. The vertical plates at both sides are vertically arranged longitudinally, and the vertical plates at the front and rear positions are vertically arranged horizontally. A plurality of adjusting grooves are vertically formed in each vertical plate, and the adjusting grooves are through grooves in the horizontal direction. A mounting plate is arranged outside each vertical plate. The adjusting studs are horizontally inserted into the adjusting grooves in a sliding fit manner. Locking nuts are coaxially engaged with the outer peripheral positions of the inner ends of all the adjusting studs close to each other. The outer ends of all the adjusting studs far from each other are fixed to the inner end faces of the corresponding mounting plates. At the same time, buffer support blocks are fixedly installed on the outer end faces of all the mounting plates far from each other.

[0012] Preferably, each of the adjusting grooves is a vertically arranged long waist-shaped groove, and handles are coaxially fixed to the end positions of the inner ends of all the adjusting studs close to each other.

[0013] Preferably, each of the locking nuts is a hand-twist knurled nut, and each of the buffer support blocks is a rubber block and the horizontal cross-sectional shape is an isosceles trapezoid with the upper base facing outwards.

[0014] Preferably, a support plate is horizontally extended and fixed to the bottom of the outer end faces of all the vertical plates far from each other, and the outer edges of the support plates do not interfere with the adjacent safety limit assemblies.

[0015] Preferably, the safety limit components each include a mating hole and a pressing stud. The tops of all the moving seats are vertically provided with the mating holes at positions away from each other, and the mating holes are through holes in the vertical direction. The mating holes are coaxially penetrated by the pressing studs in a threaded fit manner, and the bottom ends of the pressing studs are close to the bottom of the chute.

[0016] Preferably, the top end of the pressing stud is coaxially fixed with a handle for convenient gripping, and the bottom end of the pressing stud is coaxially fixed with an elastic pressing block whose outer diameter is smaller than the aperture of the mating hole.

[0017] Using the above-mentioned thin-walled part processing support device, specifically during the internal support of the thin-walled workpiece body, since a plurality of circumferentially evenly distributed internal support components are provided on the top of the base, the buffer support blocks of the internal support components can be driven to move by the internal support driving component, and the thin-walled workpiece body can be tightened from the inside in this way. The internal support method for the thin-walled workpiece body is simple and easy to operate. Specifically during operation, the air cylinder body is connected to an external air supply pipeline to conduct air and work. The air cylinder body drives the moving seat to horizontally slide along the sliding groove through the push rod. During the sliding of the moving seat, the corresponding internal support driving component is driven to move, and then the thin-walled workpiece body can be tightened and loosened from the inside. At the same time, since the buffer support blocks can be adjusted to extend and retract by moving, and the buffer support blocks are all rubber blocks in the shape of isosceles trapezoids, the buffer support blocks can be adjusted by moving and elastically pressed against the inner surface of the thin-walled workpiece body, so as to reliably internally support the thin-walled workpiece body with different cylinder diameter specifications, improving the flexibility of use of the internal support component. Before the internal support and fixation of the thin-walled workpiece body, the locking nut is screwed, and then the adjusting stud slides vertically along the adjusting groove and is pressed against the surface of the corresponding vertical plate by screwing the locking nut again, so as to adjust the support position of the buffer support block inside the thin-walled workpiece body, so that the internal support component can be adjusted to a suitable internal tightening position inside the thin-walled workpiece body, and then the internal support component can be adjusted to a position close to the processing position to provide reliable support for the processing position, further improving the flexibility of use of the internal support component. After the thin-walled workpiece body is tightened and fixed by the internal support component, by screwing the pressing stud to press the elastic pressing block against the bottom of the sliding groove, the situation that the internal support component moves due to the accidental operation of the air cylinder body can be prevented, realizing the safety limit of the internal support component, and avoiding the deformation and damage of the thin-walled workpiece body caused by accidental movement of the internal support component during the process of supporting the thin-walled workpiece body. It should be noted that during the internal support and fixation of the thin-walled workpiece body, it must be ensured that the elastic pressing blocks all leave the bottom of the sliding groove to prevent the elastic pressing blocks from interfering with the smooth movement of the moving seat along the sliding groove, and avoid the situation that the internal support component cannot tighten and fix the thin-walled workpiece body from the inside.

[0018] The beneficial effects are as follows: 1. The utility model is provided with a plurality of circumferentially evenly distributed internal support driving components and internal support components. In this way, the buffer support blocks of the internal support components can be driven to move by the internal support driving component, and the thin-walled workpiece body can be tightened from the inside. The internal support method for the thin-walled workpiece body is simple and easy to operate;

[0019] 2. Since the buffer support block can be adjusted to extend and retract by moving, and the buffer support blocks are all rubber blocks in the shape of isosceles trapezoids, the buffer support block can be adjusted by moving and elastically pressed against the inner surface of the thin-walled workpiece body, so as to provide reliable internal support for thin-walled workpiece bodies with different cylinder diameter specifications, improving the flexibility of use of the internal support assembly;

[0020] 3. By adjusting the vertical sliding of the adjusting stud along the adjusting groove and tightening the locking nut, the supporting position of the buffer support block inside the thin-walled workpiece body can be adjusted, so that the internal support assembly can be adjusted to a suitable internal tightening position inside the thin-walled workpiece body, and then the internal support assembly can be adjusted to a position close to the processing position to provide reliable support for the processing position, further improving the flexibility of use of the internal support assembly;

[0021] 4. After the thin-walled workpiece body is tightened and fixed by the internal support assembly, by turning the pressing stud to press the elastic pressing block against the bottom of the sliding groove, it is possible to prevent the internal support assembly from moving due to the accidental operation of the cylinder body, realizing the safety limit of the internal support assembly, and avoiding the deformation and damage of the thin-walled workpiece body caused by accidental movement of the internal support assembly during the process of supporting the thin-walled workpiece body.

[0035] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope protected by the present utility model.

[0036] Refer to Figures 1 - 10 ​​​​​As shown in the figure, the utility model provides a support device for processing thin-walled parts, which includes a base 3 and a thin-walled workpiece body 1. The base 3 is horizontally arranged. Inner support driving components 2 are installed on both sides and at the front and rear positions of the top surface of the base 3, and a plurality of the inner support driving components 2 are evenly distributed in the circumferential direction. Specifically, each inner support driving component 2 includes a fixed seat 204, a cylinder body 201 and a moving seat 205. Fixed seats 204 are fixedly installed on both sides and at the front and rear positions of the top surface of the base 3, and a plurality of the fixed seats 204 are evenly distributed in the circumferential direction. The fixed seats 204 at both sides are arranged horizontally, and the fixed seats 204 at the front and rear positions are arranged longitudinally. A chute 207 is formed on the top surface of each fixed seat 204 along its own direction, and the ends of all the chutes 207 close to each other are open. Sealing plates 203 are fixedly closed at the ends of all the chutes 207 away from each other. Outer end faces of all the sealing plates 203 away from each other are fixedly provided with the cylinder bodies 201 along the direction of the corresponding chutes 207. Inner ends of push rods 202 of the cylinder bodies 201 all pass through the corresponding sealing plates 203 in a sliding fit manner and enter the chutes 207. Inner ends of the push rods 202 are fixedly installed with the moving seats 205 through connecting sleeves 206. Preferably, the connecting sleeves 206 are welded to the outer surfaces of the corresponding moving seats 205. At the same time, the connecting sleeves 206 are in interference fit with the push rods 202 coaxially. And the moving seats 205 are all in horizontal sliding fit with the corresponding chutes 207. Inner support components 4 are installed at positions where the tops of all the moving seats 205 are close to each other. Safety limit components 5 are installed at positions where the tops of all the moving seats 205 are away from each other. The purpose of such a setting is that the cylinder body 201 drives the moving seat 205 to horizontally slide along the chute 207 through the push rod 202. During the sliding process of the moving seat 205, the corresponding inner support driving component 2 is driven to move, and then the thin-walled workpiece body 1 can be tightened and loosened from the inside.

[0037] See Figures 1 - 6As shown, internal support components 4 are installed at the tops of all the inner support drive components 2 at positions close to each other, so as to support the thin-walled workpiece body 1 from the inside by driving the internal support components 4 to move through the inner support drive components 2. Specifically, each internal support component 4 includes a vertical plate 401 and a mounting plate 404. Vertical plates 401 are fixedly erected at the tops of all the moving seats 205 at positions close to each other. The vertical plates 401 at both side positions are vertically arranged longitudinally, and the vertical plates 401 at front and rear positions are vertically arranged transversely. A plurality of adjustment slots 402 are vertically formed in each vertical plate 401, and the adjustment slots 402 are through slots in the horizontal direction. A mounting plate 404 is arranged outside each vertical plate 401. Adjustment studs 407 are horizontally inserted into the adjustment slots 402 in a sliding fit manner. Locking nuts 405 are coaxially engaged with the outer peripheral positions of the inner ends of all the adjustment studs 407 close to each other. The outer ends of all the adjustment studs 407 away from each other are fixed to the inner end faces of the corresponding mounting plates 404. At the same time, buffer support blocks 403 are fixed to the outer end faces of all the mounting plates 404 away from each other. The function of such a setting is that, firstly, the buffer support blocks 403 of the internal support components 4 can be driven by the inner support drive components 2 to move to tightly support the thin-walled workpiece body 1 from the inside. At the same time, since the buffer support blocks 403 can be adjusted to extend and retract by moving, then by moving and adjusting the buffer support blocks 403 and elastically pressing them against the inner surface of the thin-walled workpiece body 1, reliable internal support can be provided for thin-walled workpiece bodies 1 with different cylinder diameter specifications. Moreover, by vertically sliding the adjustment studs 407 along the adjustment slots 402 and tightening the locking nuts 405, the support positions of the buffer support blocks 403 inside the thin-walled workpiece body 1 can be adjusted, so that the internal support components 4 can be adjusted to appropriate internal tightening positions inside the thin-walled workpiece body 1.

[0038] See Figures 1 - 6As shown, safety limit components 5 are installed at the tops of all the inner support drive components 2 at positions away from each other to prevent the internal support component 4 from accidentally moving after tightening the thin-walled workpiece body 1 through the safety limit components 5. Specifically, each safety limit component 5 includes a mating hole 502 and a compression stud 503. Mating holes 502 are vertically formed at the tops of all the moving seats 205 at positions away from each other, and the mating holes 502 are through holes in the vertical direction. The compression studs 503 are coaxially inserted into the mating holes 502 in a threaded fit manner, and the bottom ends of the compression studs 503 are close to the bottom of the chute 207. The advantage of this setting is that after the thin-walled workpiece body 1 is tightened and fixed by the internal support component 4, the compression studs 503 can be screwed to press against the bottom of the chute 207 to prevent the internal support component 4 from moving due to the accidental operation of the cylinder body 201.

[0039] See Figures 1 - 6 As shown, the inner support drive component 2, the internal support component 4, and the safety limit component 5 are respectively optimized as follows. Specifically for the inner support drive component 2, each chute 207 is either a dovetail groove or an I-shaped groove, and the top surface of each moving seat 205 is not lower than the top of the corresponding chute 207. In this way, first, it is ensured that the moving seat 205 can only slide horizontally along the chute 207 and cannot escape from other directions. At the same time, by setting the top surface of the moving seat 205 not lower than the top of the chute 207, it can also ensure that the internal support component 4 can move smoothly above the top of the chute 207.

[0040] Specifically for the internal support component 4, the adjustment slots 402 are all vertically arranged waist-shaped long slots. At the end positions of the inner ends of all the adjustment studs 407 close to each other, a handle 406 is coaxially fixed. With such a setting, it is convenient for the adjustment slot 402 to have a sufficiently wide adjustment range in the vertical direction, and at the same time, it is convenient to drive the adjustment stud 407 to slide vertically along the adjustment slot 402 by holding the handle 406. Optionally, the lock nuts 405 are all hand-tightening knurled nuts, so that it is convenient to directly hold the lock nuts 405 for tightening and loosening operations. The buffer support blocks 403 are all rubber blocks and the horizontal cross-sectional shapes are all isosceles trapezoids with the upper base facing outwards. With such a setting, by moving and adjusting the buffer support blocks 403 and elastically pressing them against the inner surface of the thin-walled workpiece body 1, reliable internal support can be provided for the thin-walled workpiece bodies 1 with different cylinder diameter specifications. Further optionally, at the bottom of the outer end faces of all the vertical plates 401 away from each other, a support plate 408 is horizontally extended and fixed, and the outer edges of the support plate 408 do not interfere with the adjacent safety limit components 5. Preferably, the outer edges of the support plate 408 do not interfere with the handles 406 and the pressing studs 503 of the corresponding safety limit components 5. With such a setting, it is convenient to support the thin-walled workpiece body 1 well by supporting the bottom end face of the thin-walled workpiece body 1 with the support plate 408.

[0041] Specifically for the safety limit component 5, at the top of the pressing stud 503, a head 501 for convenient holding is coaxially fixed, so as to drive the pressing stud 503 to perform forward and reverse rotation operations by applying force by holding the head 501. At the same time, at the bottom of the pressing stud 503, an elastic pressing block 504 with an outer diameter smaller than the aperture of the mating hole 502 is coaxially fixed. With such a setting, by directly contacting the bottom of the chute 207 with the elastic pressing block 504, the bottom of the chute 207 can be prevented from being damaged. At the same time, by the elastic deformation of the elastic pressing block 504, the reliability of restricting the accidental movement of the moving seat 205 along the chute 207 can also be improved.

[0042] With the above structure, specifically during the process of internally supporting the thin-walled workpiece body 1, since a plurality of the internal support components 4 evenly distributed in the circumferential direction are provided on the top of the base 3, the buffer support blocks 403 of the internal support components 4 can be driven by the internal support driving component 2 to move, and in this way, the thin-walled workpiece body 1 can be tightened from the inside. The internal support method for the thin-walled workpiece body 1 is simple and easy to operate. Specifically during operation, the air cylinder body 201 is connected to an external air supply pipeline to conduct air and work. The air cylinder body 201 drives the moving seat 205 to horizontally slide along the sliding groove 207 through the push rod 202. During the sliding process of the moving seat 205, the corresponding internal support driving component 2 is driven to move, and then the thin-walled workpiece body 1 can be tightened and loosened from the inside. At the same time, since the buffer support blocks 403 can be adjusted to extend and retract by moving, and the buffer support blocks 403 are all rubber blocks in the shape of isosceles trapezoids, then by adjusting the movement of the buffer support blocks 403 and elastically pressing the buffer support blocks 403 against the inner surface of the thin-walled workpiece body 1, reliable internal support can be provided for the thin-walled workpiece body 1 with different cylinder diameter specifications, improving the flexibility of use of the internal support component 4. Before internally supporting and fixing the thin-walled workpiece body 1, the locking nut 405 is screwed, and then the adjusting stud 407 slides vertically along the adjusting groove 402 and is pressed against the surface of the corresponding vertical plate 401 by screwing the locking nut 405 again, so as to adjust the supporting position of the buffer support block 403 inside the thin-walled workpiece body 1. In this way, the internal support component 4 can be adjusted to a suitable internal tightening position inside the thin-walled workpiece body 1, and then the internal support component 4 can be adjusted to a position close to the processing position to provide reliable support for the processing position, further improving the flexibility of use of the internal support component 4. After the thin-walled workpiece body 1 is tightened and fixed by the internal support component 4, by screwing the pressing stud 503 to press the elastic pressing block 504 against the bottom of the sliding groove 207, the situation that the internal support component 4 moves due to the accidental operation of the air cylinder body 201 can be prevented, realizing the safety limit of the internal support component 4, and avoiding the deformation and damage of the thin-walled workpiece body 1 caused by accidental movement of the internal support component 4 during the process of supporting the thin-walled workpiece body 1. It should be noted that during the process of internally supporting and fixing the thin-walled workpiece body 1, it must be confirmed first that the elastic pressing blocks 504 all leave the bottom of the sliding groove 207 to prevent the elastic pressing blocks 504 from interfering with the smooth movement of the moving seat 205 along the sliding groove 207, and avoiding the situation that the internal support component 4 cannot tighten and fix the thin-walled workpiece body 1 from the inside.

[0043] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims described above.
