Description

Technical Field

[0001] This invention relates to the field of machine tool equipment technology, specifically a grinding device for the inner surface of an arc-shaped thin-walled part. Background Technology

[0002] Grinding is a surface modification technique. It generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of a material surface through friction. Its main purpose is to obtain a specific surface roughness.

[0003] When grinding, ordinary CNC machine tools need to fix the parts to be ground. However, when clamping and fixing curved workpieces, the curved workpieces are prone to deformation, which affects the grinding effect. In addition, ordinary CNC machine tools cannot continuously feed curved workpieces in a cyclic manner, which can easily lead to a decrease in grinding efficiency. Ordinary CNC grinding machines require multiple grinding operations when grinding curved surfaces, resulting in low efficiency. Summary of the Invention

[0013] As a further embodiment of the present invention: there are two sets of toothed push plates, two sets of adjusting gear blocks, and a storage clamp groove is fixedly connected to the inner wall of the feeding cavity of the arc-shaped thin-walled part.

[0018] Compared with the prior art, the beneficial effects of the present invention are: it facilitates continuous feeding of material into the grinding mechanism during the grinding process, which is conducive to improving the grinding efficiency of arc-shaped thin-walled parts, facilitating rapid grinding of arc-shaped thin-walled parts, and preventing deformation of arc-shaped thin-walled parts during the grinding process.

[0019] 1. Through the feeding clamp mechanism, during use, the first motor drives the drive gear fixedly connected to the output end to rotate, thereby driving the meshing adjustment and positioning gear ring to rotate. The rotating adjustment and positioning gear ring drives the adjustment gear block meshing on the inner side of the bottom end to rotate clockwise. The clockwise rotating adjustment gear block drives the toothed push plate meshing on the outer side of the bottom to slide to one end, thereby pulling the discharge plate fixedly connected to one end of the toothed push plate to slide to one end. At the same time, it drives the partition plate fixedly connected to the top of the discharge plate to slide into the feeding cavity of the arc-shaped thin-walled part, thereby separating the arc-shaped thin-walled part clamped between the discharge plate and the partition plate from the arc-shaped thin-walled part on the partition plate. As the discharge plate slides, it drives the first auger to rotate. This rotation, in turn, drives the engaged second auger to rotate. The rotating second auger causes the telescopic pressure rod, slidably connected to the outside, to slide downwards, pressing down on one end of the first folding push plate. This causes the first folding push plate to extend and open, causing the grinding wheel mounting plate, fixedly connected to one end of the first folding push plate, to slide to one side. During this sliding process, the grinding wheel mounting plate, via the arc-shaped toothed cavity plate rotatably connected to its bottom end, pulls the second folding push plate, also fixedly connected to one end, to extend and open. As the second folding push plate extends, it causes the first track limiting plate to slide along the track groove fixedly connected to one side of the second track limiting plate. Sliding towards one end of the second track limiting plate, when the discharge plate slides and retracts into the wall cavity of the arc-shaped thin-walled part's feeding chamber, the separated arc-shaped thin-walled part slides down and gets stuck in the anti-deformation arc plate after losing drag. The support block fixedly connected to the bottom of the grinding wheel mounting plate holds the arc-shaped thin-walled part in place. When the first folding push plate drives the grinding wheel mounting plate to slide to one end and clamp onto one end of the arc-shaped thin-walled part, it causes the grinding wheel, which is rotated and connected to the middle of one end of the grinding wheel mounting plate, to get stuck on the inner wall of the arc-shaped thin-walled part. When the adjusting gear block contacts the tooth block in the inner wall of the adjusting positioning gear ring, it drives the meshing adjusting gear block to rotate counterclockwise. The counterclockwise rotating adjusting gear block drives the meshing... The discharge plate, fixedly connected to one end of the toothed push plate, slides into the feeding cavity of the arc-shaped thin-walled part. At the same time, it drives the partition plate fixedly connected to the top of the feeding cavity to slide outward. This causes the arc-shaped thin-walled part supported by the hoop in the feeding cavity to slide down and be stuck to the top of the discharge plate. This cyclical pushing facilitates rapid feeding and distribution, and helps prevent other arc-shaped thin-walled parts from scattering out of the feeding cavity during the feeding process. This facilitates continuous feeding into the grinding mechanism during the grinding process, thereby improving the grinding efficiency of the arc-shaped thin-walled part.

[0020] 2. Through the established grinding clamping mechanism, during grinding, the second motor drives the bevel gear rod fixedly connected to the output end to rotate. The rotating bevel gear rod drives the double-headed bevel gear rod meshing at one end to rotate. The rotating double-headed bevel gear rod drives the bevel gear block meshing at one end to rotate. The rotating bevel gear block drives the second folding push plate fixedly connected to the outside of the fixed turntable to rotate clockwise through the fixed connecting turntable at the top. The rotating second folding push plate drives the arc-shaped toothed cavity plate fixedly connected at one end to rotate clockwise. The clockwise rotation of the arc-shaped toothed cavity plate drives the grinding wheel meshing at the top to rotate, grinding the inner wall of the arc-shaped thin-walled part. When the tooth groove on the conical drive block fixedly connected to the top of the conical gear rod rotates clockwise and engages with the conical gear ring at the bottom of the stacked gear ring plate, the stacked gear ring plate rotates. The rotating stacked gear ring plate causes the meshing anti-deformation arc plate to rotate by a specified angle, thereby causing the arc-shaped thin-walled component of the inner clamp of the anti-deformation arc plate to move to a certain position with the rotation of the anti-deformation arc plate. The moved position is then ground. When the second motor drives the conical gear rod fixedly connected to the output end to rotate in the opposite direction, the reverse-rotating conical gear rod drives the double-headed conical gear rod meshing at one end to rotate in the opposite direction. The reverse-rotating double-headed conical gear rod drives the conical gear block meshing at one end of the double-headed conical gear rod to rotate in the opposite direction. The conical gear block rotates in the opposite direction, driving the second folding push plate fixed to the outside of the fixed turntable to rotate counterclockwise via the fixed connecting turntable at the top. This counterclockwise rotation of the second folding push plate drives the arc-shaped toothed cavity plate fixed at one end to rotate counterclockwise. The counterclockwise rotation of the arc-shaped toothed cavity plate drives the grinding wheel, which is meshed at the top, to rotate counterclockwise to grind the inner wall of the arc-shaped thin-walled part. As the toothed groove on the conical drive block fixed at the top of the conical gear rod rotates counterclockwise, it engages with the conical toothed ring at the bottom of the stacked toothed ring plate, thus driving the stacked toothed ring plate to rotate counterclockwise. This counterclockwise rotation of the stacked toothed ring plate drives the meshed anti-deformation arc plate to rotate by a specified angle, thereby... The curved thin-walled component with the inner clamp of the anti-deformation arc plate moves to a certain position as the anti-deformation arc plate rotates counterclockwise. The moved position is then ground. During grinding, the powder and slag falling off are separated by the anti-deformation arc plate and the grinding wheel mounting plate, which helps prevent the slag from splashing out during grinding. The slag slides into the dust collection box at one end of the bottom of the grinding wheel mounting plate along the inclined angle of the bottom of the grinding wheel mounting plate. This facilitates the rotation and adjustment of the position of the curved thin-walled component during the rapid grinding process, and prevents the slag from splashing everywhere during grinding. This facilitates the rapid grinding of the curved thin-walled component and helps prevent deformation of the curved thin-walled component during grinding. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0031] A grinding device for the inner surface of an arc-shaped thin-walled part, please refer to [link / reference]. Figures 1-7 In this embodiment of the invention, the first motor 412 drives the discharge plate 44 on the feeding clamp mechanism 4 to slide open, allowing the arc-shaped thin-walled part in the feeding cavity 41 to slide down into the anti-deformation arc plate 55. The first folding push plate 410 extends and drives the grinding wheel mounting plate 513 to move to one end, thereby causing the grinding wheel 510 mounted on the grinding wheel mounting plate 513 to slide to one end and lock onto the inner wall of the arc-shaped thin-walled part. Then, the second motor 51 drives the grinding wheel 510 to rotate and grind the inner wall of the arc-shaped thin-walled part. The dust from the grinding is guided by the inclined angle at the bottom of the grinding wheel mounting plate 513 and slides into the dust collection box 512. This facilitates rapid and cyclical feeding while preventing the arc-shaped thin-walled part to be ground from deforming during the grinding process.

[0032] During feeding, the first motor 412 drives the drive gear 414, which is fixedly connected to the output end, to rotate. This, in turn, drives the meshing adjustment and positioning gear ring 46 to rotate. The rotating adjustment and positioning gear ring 46 drives the adjustment gear block 413, which is meshed on the inner side of the bottom end, to rotate clockwise. The clockwise rotation of the adjustment gear block 413 drives the toothed push plate 45, which is meshed on the outer side of the bottom, to slide to one end. This pulls the discharge plate 44, which is fixedly connected to one end of the toothed push plate 45, to slide to one end. At the same time, it drives the partition plate 42, which is fixedly connected to the top of the discharge plate 44, to slide into the feeding cavity 41 of the arc-shaped thin-walled part. This separates the arc-shaped thin-walled part clamped between the discharge plate 44 and the partition plate 42 from the arc-shaped thin-walled part on the partition plate 42. As the discharge plate 44 slides, it drives the first spiral rod 43 to rotate. The first spiral rod 43, in turn, drives the meshing second spiral rod 48 to rotate. The rotating second spiral rod 48 causes the telescopic pressure rod 49, slidably connected on the outside, to slide downwards and push one end of the first folding push plate 410, causing the first folding push plate 410 to extend and open. This causes the grinding wheel mounting plate 513, fixedly connected to one end of the first folding push plate 410, to slide to one end. During this sliding process, the grinding wheel mounting plate 513, through the arc-shaped toothed cavity plate 59 rotatably connected at its bottom end, pulls the second folding push plate 58, fixedly connected to one end, to extend and open. As the second folding push plate 58 extends, it drives the first track limiting plate 514 along the first... The track groove fixedly connected to one side of the second track limiting plate 516 slides towards one end of the second track limiting plate 516. When the discharge plate 44 slides and retracts into the wall cavity of the arc-shaped thin-walled part feeding chamber 41, the separated arc-shaped thin-walled part slides down and gets stuck in the anti-deformation arc plate 55 after losing drag. The support block fixedly connected to the bottom of the grinding wheel mounting plate 513 holds the arc-shaped thin-walled part in place. When the first folding push plate 410 drives the grinding wheel mounting plate 513 to slide to one end and clamp onto one end of the arc-shaped thin-walled part, the grinding wheel 510, which is rotated and connected to the middle of one end of the grinding wheel mounting plate 513, gets stuck on the inner wall of the arc-shaped thin-walled part. When the adjusting gear block 413 contacts the tooth block in the inner wall of the adjusting positioning gear ring 46, it engages. The connecting adjusting gear block 413 rotates counterclockwise. The counterclockwise rotation of the adjusting gear block 413 drives the meshing toothed push plate 45, one end of which is fixedly connected to the discharge plate 44, to slide into the arc-shaped thin-walled part feeding cavity 41. At the same time, it drives the partition plate 42, which is fixedly connected to the top of the arc-shaped thin-walled part feeding cavity 41, to slide outward of the arc-shaped thin-walled part feeding cavity 41. This causes the arc-shaped thin-walled part on the upper hoop of the arc-shaped thin-walled part feeding cavity 41 to slide down and be stuck to the top of the discharge plate 44. The parts are pushed in a cycle, which facilitates rapid feeding and distribution. This helps to prevent the remaining arc-shaped thin-walled parts in the arc-shaped thin-walled part feeding cavity 41 from falling out during the feeding process.

[0033] The top view of the adjusting positioning gear ring 46 is a concentric ring. Both the inner and outer cavity walls are fixedly connected with tooth groove groups, and the number of tooth groove groups is matched. A rack column block is fixedly connected to the middle of the top of the adjusting gear block 413. The rack column block meshes with the adjusting positioning gear ring 46. When the adjusting positioning gear ring 46 rotates, the tooth groove group on the outer cavity wall contacts the adjusting gear block 413, causing the adjusting gear block 413 to rotate clockwise. When the adjusting positioning gear ring 46 rotates, the tooth groove group on the inner cavity wall contacts the adjusting gear block 413, causing the adjusting gear block 413 to rotate counterclockwise, which facilitates the sliding and changing position of the tooth groove push plate 45.

[0034] A connecting plate is fixedly connected between the partition plate 42 and the discharge plate 44. A spiral hole is fixedly connected to one end of the connecting plate, and a first spiral rod 43 is slidably connected to the inner side of the spiral hole. When the partition plate 42 and the discharge plate 44 slide inward and outward, the first spiral rod 43 will be driven to rotate through the spiral hole fixedly connected to one end of the connecting plate.

[0035] During grinding, the second motor 51 drives the bevel gear rod 52, which is fixedly connected to the output end, to rotate. The rotating bevel gear rod 52 drives the double-headed bevel gear rod 56, which is meshed with the bottom end of the double-headed bevel gear rod 56, to rotate. The rotating double-headed bevel gear rod 56 drives the bevel gear block 57, which is meshed with the top end of the double-headed bevel gear rod 56, to rotate. The rotating bevel gear block 57 drives the second folding push plate 58, which is fixedly connected to the outside of the fixed connecting turntable 515, to rotate clockwise. The rotating second folding push plate 58 drives the arc-shaped toothed cavity plate 59, which is fixedly connected to one end, to rotate clockwise. The clockwise rotating arc-shaped toothed cavity plate 59 drives the grinding wheel 510, which is meshed with the top end, to rotate and grind the inner wall of the arc-shaped thin-walled part. During grinding, when the tooth groove on the conical drive block 53, which is fixedly connected to the top of the conical gear rod 52, rotates clockwise and engages with the conical tooth ring at the bottom of the stacked tooth ring plate 54, the stacked tooth ring plate 54 rotates. The rotating stacked tooth ring plate 54 drives the meshing anti-deformation arc plate 55 to rotate by a specified angle, thereby causing the arc-shaped thin-walled part of the inner clamp of the anti-deformation arc plate 55 to move to a certain position with the rotation of the anti-deformation arc plate 55. Grinding continues on the moved position. When the second motor 51 drives the conical gear rod 52, which is fixedly connected to the output end, to rotate in the opposite direction, the reverse-rotating conical gear rod 52 drives the double-headed conical tooth rod 56, which is meshed at one end, to rotate in the opposite direction. The reverse-rotating double-headed conical tooth rod 56 drives the double-headed conical tooth rod 56 to rotate in the opposite direction. The bevel gear block 57, which is meshed at the top of one end of the rack 56, rotates in the opposite direction. This counter-rotating bevel gear block 57 drives the second folding push plate 58, which is fixedly connected to the outside of the fixed-connection turntable 515, to rotate counter-clockwise via the fixed-connection turntable 515. The counter-clockwise rotating second folding push plate 58 drives the arc-shaped toothed cavity plate 59, which is fixedly connected at one end, to rotate counter-clockwise. The counter-clockwise rotating arc-shaped toothed cavity plate 59 drives the grinding wheel 510, which is meshed at the top, to rotate counter-clockwise to grind the inner wall of the arc-shaped thin-walled part. When the tooth groove on the conical drive block 53, which is fixedly connected to the top of the bevel gear rod 52, rotates counter-clockwise, it engages with the conical toothed ring at the bottom of the stacked toothed ring plate 54, thereby causing the stacked toothed ring plate 54 to rotate counter-clockwise. The clockwise rotating superimposed toothed ring plate 54 drives the meshing anti-deformation arc plate 55 to rotate by a specified angle, thereby causing the arc-shaped thin-walled component of the inner clamp of the anti-deformation arc plate 55 to move to a certain position as the anti-deformation arc plate 55 rotates counterclockwise. The moved position is then ground. The powder and slag that fall during grinding are separated by the anti-deformation arc plate 55 and the grinding wheel mounting plate 513, which helps to prevent the slag from splashing out during the grinding process. The slag slides into the dust collection box 512 at one end of the bottom of the grinding wheel mounting plate 513 along the inclined angle of the bottom of the grinding wheel mounting plate 513. This makes it easy to rotate and adjust the position of the arc-shaped thin-walled component during the rapid grinding process, and also helps to prevent the slag from splashing everywhere during the grinding process.

[0036] A conical toothed ring is fixedly connected to the inner bottom of the stacked toothed ring plate 54. The conical toothed ring meshes with the conical drive block 53. Multiple tooth grooves are fixedly connected to one end of the top of the conical drive block 53. The shape formed by the multiple tooth grooves is fan-shaped.

[0037] A mating rotating toothed block is fixedly connected to the middle of the bottom end of the grinding wheel 510. When the arc-shaped toothed cavity plate 59 rotates, it is convenient to drive the grinding wheel 510 fixedly connected to the top of the mating rotating toothed block to rotate through the meshing mating rotating toothed block. This facilitates the rapid and simultaneous rotation of multiple grinding wheels 510, which is beneficial to improving the grinding efficiency of arc-shaped thin-walled parts.

[0038] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
