Description

Technical Field

[0001] This invention belongs to the field of parts clamping technology, specifically a fixture for machining thin-walled parts. Background Technology

[0002] A fixture, composed of positioning elements, clamping devices, connecting elements, and a fixture base, is widely used in industrial parts processing. However, when machining thin-walled parts, such as the pickling of aviation kerosene filter cylinders, custom-made fixtures are required to meet the precision machining needs. Aviation kerosene filter cylinders are high-precision parts, possessing advantages such as high filtration efficiency and long service life. The filter unit of an aviation kerosene filter cylinder is constructed by welding multiple main ribs and metal wires wound around them.

[0003] In existing technologies, metal pickling processes utilize acidic solutions to chemically react with metal surfaces, removing oxides and contaminants. When pickling aviation kerosene filter cylinders, it is necessary to first prepare an acidic solution, a pickling tank, and agitation equipment. Then, multiple aviation kerosene filter cylinders to be pickled are placed in the pickling tank and immersed in the acidic solution. Based on the results of the first pickling, the pickling process can be repeated several times, with the reaction rate accelerated by agitation equipment until the quality requirements are met.

[0004] However, it should be emphasized that during the pickling process, collisions between aviation kerosene filter cylinders may cause surface scratches and dents, which have a direct and adverse impact on the manufacturing quality of the parts. Summary of the Invention

[0056] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0057] like Figures 1 to 8 As shown, the present invention discloses a machining fixture for thin-walled parts, comprising:

[0058] The fixed plate 1 has a top hook 11 at the center of its top surface and a clamping module at the center of its bottom surface.

[0059] The clamping module includes:

[0060] The fixing rod 4 has one end fixedly connected to the center of the bottom surface of the fixing plate 1, and the other end away from the fixing plate 1 has an internal thread.

[0061] A movable ring 2 is fitted onto a fixed rod 4. The movable ring 2 has a cavity 21 inside. The side wall of the movable ring 2 has four perforations 22 evenly spaced.

[0062] The first rotating rod 23 is evenly arranged in the first cavity 21. The first rotating rod 23 is rotatably connected to the first cavity 21. The number of the first rotating rod 23 is four.

[0063] A first fixing ring 24 is sleeved on the first rotating rod 23, located in the middle of the first rotating rod 23, and fixedly connected to the first rotating rod 23. The length of the first fixing ring 24 is less than that of the rotating rod.

[0064] The first torsion spring 25 is respectively sleeved on both ends of the first rotating rod 23, one end is fixedly connected to the inner wall of the first cavity 21, and the other end away from the inner wall of the first cavity 21 is fixedly connected to the first fixing ring 24.

[0065] One end of the first connecting rope 26 is fixed to the first fixing ring 24, and the first connecting rope 26 is wrapped around the first fixing ring 24.

[0066] The bottom of hook 27 is fixedly connected to the end of connecting rope 26 away from fixing ring 24.

[0067] Threaded rod 5, one end of which is threadedly connected to fixed rod 4;

[0068] The movable disk 3 is located at the end of the threaded rod 5 away from the fixed rod 4. The movable disk 3 has a second cavity 31 inside. The side wall of the movable disk 3 is evenly provided with two through holes 32. The number of the two through holes 32 is four.

[0069] The second rotating rod 33 is evenly arranged in the second cavity 31. The second rotating rod 33 is rotatably connected to the second cavity 31. The number of the second rotating rod 33 is four.

[0070] The second fixing ring 34 is sleeved on the second rotating rod 33, located in the middle of the second rotating rod 33, and fixedly connected to the second rotating rod 33. The length of the second fixing ring 34 is less than that of the rotating rod.

[0071] The second torsion spring 35 is respectively sleeved on both ends of the second rotating rod 33. One end is fixedly connected to the inner wall of the second cavity 31, and the other end away from the inner wall of the second cavity 31 is fixedly connected to the second fixing ring 34.

[0072] The second connecting rope 36 is fixed at one end to the second fixing ring 34, and the second connecting rope 36 is wrapped around the second fixing ring 34;

[0073] The bottom of hook 37 is fixedly connected to the end of the second connecting rope 36 away from the first fixing ring 24.

[0074] Specifically, when pickling small, thin-walled parts, such as small aviation kerosene filter cylinders, is required, firstly, the operator tightens the threaded rod 5 according to the length of the small aviation kerosene filter cylinder until the distance between the first fixing ring 24 and the second fixing ring 34 is slightly smaller than the length of the small aviation kerosene filter cylinder to be clamped; secondly, the thin-walled part processing fixture is placed inside the small aviation kerosene filter cylinder, and the first hook 27 is pulled out according to the diameter of the upper end of the small aviation kerosene filter cylinder, passing through the small aviation kerosene filter cylinder to be clamped. The mesh at the top of the oil filter cylinder is fixed to it. At this time, the first hook 27 pulls out the first connecting rope 26 located in the first cavity 21. The part of the first connecting rope 26 wrapped around the first fixing ring 24 is pulled out from the first through hole 22. At the same time, the first connecting rope 26 drives the first rotating rod 23 to rotate. The rotation of the first rotating rod 23 causes the first torsion springs 25 at both ends of the first rotating rod 23 to be stressed at the same time, storing elastic potential energy, and finally ensuring that the first hook 27 is firmly fixed to the mesh at the top of the small aviation kerosene filter cylinder.

[0075] Next, based on the diameter of the lower end of the small aviation kerosene filter cylinder, the operator pulls out the second hook 37, passes it through the mesh of the lower end of the small aviation kerosene filter cylinder that needs to be clamped, and fixes it thereto. At this time, the second hook 37 pulls out the second connecting rope 36 located in the second cavity 31. The part of the second connecting rope 36 wrapped around the second fixing ring 34 is pulled out from the second through hole 32. At the same time, the second connecting rope 36 drives the second rotating rod 33 to rotate. The rotation of the second rotating rod 33 causes the second torsion spring 35 at both ends of the second rotating rod 33 to be stressed, storing elastic potential energy, ensuring that the second hook 37 is firmly fixed on the mesh of the lower end of the small aviation kerosene filter cylinder.

[0076] After completing these steps, the thin-walled parts processing fixture clamps the small aviation kerosene filter cylinder. At this point, the operator connects the top hook 11 to the pickling rack, which is connected to the output end of the telescopic element. The telescopic element can be a telescopic cylinder, a telescopic hydraulic cylinder, or a telescopic rod. Then, the small aviation kerosene filter cylinder to be pickled is placed in the pickling tank, and the pickling of the small aviation kerosene filter cylinder is achieved by the up-and-down movement of the output end of the telescopic element.

[0077] When multiple small aviation kerosene filter cylinders need to be acid-washed, the staff first tightens the threaded rod 5 according to the length of the small aviation kerosene filter cylinders until the distance between the first fixing ring 24 and the second fixing ring 34 is slightly smaller than the length of the small aviation kerosene filter cylinders that need to be clamped.

[0078] Then, the thin-walled parts processing fixture with adjusted length is placed into multiple small aviation kerosene filter cylinders in sequence, and the first hook is pulled out one by one. The first connecting rope passes through the mesh of the small aviation kerosene filter cylinders to connect the horizontally adjacent small aviation kerosene filter cylinders to form a small aviation kerosene filter cylinder aggregate.

[0079] Finally, hook the top hook 11 onto the pickling rack, which is connected to the output end of the telescopic element. At this point, the multiple small aviation kerosene filter cylinders requiring pickling can be placed together into the pickling tank. The pickling of the multiple small aviation kerosene filter cylinders is achieved by the up-and-down movement of the telescopic element.

[0080] Compared with existing technologies, this invention achieves clamping of thin-walled parts through a simple structure, avoiding collisions between thin-walled parts and reducing the probability of surface scratches and dents. Secondly, this invention improves applicability by clamping thin-walled parts of different diameters and heights. Finally, this invention can clamp multiple thin-walled parts, improving operational flexibility and efficiency.

[0081] In a preferred embodiment of the present invention, the movable ring 2 is provided with a first elastic pad 28 evenly on its side, the first elastic pad 28 being located between adjacent first perforations 22, and the number of first elastic pads 28 is four; the movable disk 3 is provided with a second elastic pad 38 evenly on its side, the elastic pad being located between adjacent second perforations 32, and the number of second elastic pads 38 is four.

[0082] Specifically, when it is necessary to clamp thin-walled parts with small diameters, the first elastic pad 28 and the second elastic pad 38 prevent the thin-walled parts from directly contacting the moving ring 2 and the moving disk 3, while providing cushioning and further reducing the probability of deformation of the thin-walled parts.

[0083] In a preferred embodiment of the present invention, a first threaded groove 39 is provided at the center of the top surface of the movable disk 3, and the first threaded groove 39 is threadedly connected to the threaded rod 5.

[0084] Specifically, when the movable disk 3 needs to be repaired or replaced, it is only necessary to rotate the movable disk 3 so that the movable disk 3 can be fixed and disassembled with the threaded rod 5 through the first threaded groove 39. The easy disassembly of the movable disk 3 and the threaded rod 5 improves the working efficiency of the present invention.

[0085] In a preferred embodiment of the present invention, an external threaded ring 41 is fitted on the fixed rod 4, and the external threaded ring 41 is fixedly connected to the fixed rod 4. An internal threaded hole is opened in the center of the movable ring 2, and the movable ring 2 is threadedly connected to the external threaded ring 41.

[0086] Specifically, the operator can rotate the movable ring 2 to move it up and down along the external threaded ring 41 until the distance between the movable ring 2 and the movable disk 3 is slightly less than the height of the thin-walled part, and then clamp the thin-walled part. The movable ring 2, in conjunction with the external threaded ring 41, realizes the up and down movement of the movable ring 2, which improves the adaptability of the invention to thin-walled parts of different heights.

[0087] In a preferred embodiment of the present invention, rubber pads 10 are laid on the inner sides of both the first hook 27 and the second hook 37.

[0088] Specifically, when it is necessary to clamp thin-walled parts, both hook 27 and hook 37 need to be in direct contact with the mesh on the thin-walled parts. The rubber pad 10 makes the contact between the mesh on the thin-walled parts and hooks 27 and 37 more gentle, further reducing the probability of deformation of the thin-walled parts during processing.

[0089] In a preferred embodiment of the present invention, the first connecting rope 26 and the second connecting rope 36 are made of corrosion-resistant material.

[0090] Specifically, the materials constituting the first connecting rope 26 and the second connecting rope 36 can be steel wire rope, ceramic fiber rope, etc. The corrosion resistance of the first connecting rope 26 and the second connecting rope 36 improves the service life of the invention, reduces the replacement frequency of the first connecting rope 26 and the second connecting rope 36, and improves work efficiency.

[0091] In a preferred embodiment of the present invention, the clamping module includes:

[0092] The clamping module includes:

[0093] A fixing post 6 is fixedly connected at one end to the bottom surface of the fixing plate 1, and the diameter of the fixing post 6 is smaller than that of the fixing plate 1.

[0094] The sealing disc 61 is fixedly connected to the end of the fixing column 6 away from the fixing disc 1;

[0095] Sleeve 62 has an internal thread on its inner wall. Sleeve 62 is threadedly connected to sealing disc 61. A threaded opening is provided at the center of the top of sleeve 62. The threaded opening is threadedly connected to fixed post 6.

[0096] Ventilation holes 7 are evenly distributed on the side wall of the sleeve 62, located at the bottom of the sleeve 62, and there are four of them.

[0097] The fixing block 72 is symmetrically arranged on the inner wall of the vent hole 7, located inside the vent hole 7, and fixedly connected to the inner wall of the vent hole 7.

[0098] Spring 71 is fixedly connected at one end to the fixing block 72;

[0099] The disc 73 is located inside the vent 7 and is slidably sealed with the vent 7. The side near the fixing block 72 is fixedly connected to the first spring 71.

[0100] One end of the thin rod 74 is fixedly connected to the center of the side of the disc 73 away from the first spring 71;

[0101] The blocking block 75 is symmetrically arranged on the inner wall of the vent hole 7, located on the outer side of the vent hole 7, and fixedly connected to the inner wall of the vent hole 7.

[0102] The second threaded groove 8 is located on the bottom surface of the sleeve 62, and an internal thread is provided on the inner wall of the second threaded groove 8;

[0103] Two springs 81 are fixedly connected at one end to the bottom surface of the second threaded groove 8;

[0104] The spiral rod 82 is helically driven by the second threaded groove 8. The upper end of the spiral rod 82 is provided with an annular groove 83, and the second spring 81 is slidably connected to the annular groove 83.

[0105] The rotating disk 84 is fixedly connected to the lead screw at its top center, and the diameter of the rotating disk 84 is larger than the diameter of the sleeve 62.

[0106] When it is necessary to pickle large thin-walled parts, such as large aviation kerosene filter cylinders, the thin-walled parts processing fixture is first placed into the large aviation kerosene filter cylinder. Then, by rotating the fixed disk 1, the fixed column 6 and the sealing disk 61 are moved down. At this time, the fixed column 6 rotates down along the threaded opening, which drives the sealing disk 61 to rotate down along the internal thread of the inner wall of the sleeve 62. This increases the pressure in the space under the sealing disk 61. The increased pressure pushes the disc 73 to slide from the inside to the outside in the vent hole 7 until the disc 73 is in contact with the blocking block 75. The sliding of the disc 73 drives the thin rod 74 to move outward, which also causes the first spring 71 to extend. The thin rod 74 extends into the mesh of the large aviation kerosene filter cylinder. All four thin rods 74 pass through the mesh of the large aviation kerosene filter cylinder, thus fixing the large aviation kerosene filter cylinder.

[0107] Then, connect the top hook 11 on the fixed plate 1 to the pickling hanger, and put the large aviation kerosene filter cylinder into the pickling tank. The pickling hanger and the output end of the telescopic element are fixed. As the output end of the telescopic element moves up and down, the large aviation kerosene filter cylinder is pickled.

[0108] When the output end of the telescopic element moves the large aviation kerosene filter cylinder downward through the thin-walled parts processing fixture, the rotating disk 84 contacts the bottom of the pickling tank, so that the rotating disk 84 receives an upward force. The spiral column moves upward along the second thread groove 8, and the spiral column drives the rotating disk 84 to rotate. At the same time, the annular groove 83 keeps the second spring 81 relatively stationary, and the upward spiral column compresses the second spring 81.

[0109] When the output end of the telescopic element moves the large aviation kerosene filter cylinder upward through the thin-walled parts processing fixture, the compressed No. 2 spring 81 begins to stretch, causing the spiral column to be subjected to a downward force. With the cooperation of the No. 2 thread groove 8 and the ring groove 83, the spiral column drives downward through the spiral drive, and the spiral column drives the rotating disk 84 to rotate and move downward.

[0110] After the large aviation kerosene filter cylinder is acid-washed, simply rotate the fixed plate 1 to move the fixed column 6 and the sealing plate 61 upward. The pressure in the space under the sealing plate 61 decreases, causing the disc 73 and the thin rod 74 to move into the vent hole 7. The first spring 71 contracts, causing the thin rod 74 to retract from the mesh of the large aviation kerosene filter cylinder, thus no longer clamping the large aviation kerosene filter cylinder.

[0111] The sealing disc 61, in conjunction with the disc 73 and the thin rod 74, secures the large aviation kerosene filter cylinder, enabling clamping of large aviation kerosene filter cylinders of different diameters and improving the applicability of the invention. The cooperation of the second spring 81, the spiral rod 82, the second threaded groove 8, and the rotating disc 84 enables the oscillation of the pickling solution, improving the pickling effect on the large aviation kerosene filter cylinder during clamping. At the same time, after pickling, it removes the pickling solution remaining on the large aviation kerosene filter cylinder.

[0112] In a preferred embodiment of the present invention, the rotating disk 84 is provided with swing rods 9 evenly, the swing rods 9 are located on the outer side of the top surface of the rotating disk 84, and a rubber ball 91 is fixedly connected to the end of the swing rods 9 away from the rotating disk 84.

[0113] Specifically, when the output end of the telescopic element moves the large aviation kerosene filter cylinder downward through the thin-walled parts processing fixture, the rotating disk 84 causes the rubber ball 91 on the swing rod 9 to touch the inner wall of the large aviation kerosene filter cylinder, shaking off the impurities generated during the pickling process, and at the same time oscillating the pickling solution to increase the pickling effect.

[0114] When the output end of the telescopic element moves the large aviation kerosene filter cylinder upward through the thin-walled parts processing fixture, the compressed No. 2 spring 81 begins to extend, causing the spiral column to be subjected to a downward force. Under the cooperation of the No. 2 threaded groove 8 and the annular groove 83, the spiral column rotates downward, causing the rotating disk 84 to rotate and move downward. The rubber ball 91 contacts the large aviation kerosene filter cylinder, which can also shake off the impurities generated during the pickling process, agitate the pickling solution, and increase the pickling effect. Furthermore, at the moment when the thin-walled parts processing fixture is removed from the pickling solution after pickling, the No. 2 spring 81 extends further due to the disappearance of the buoyancy of the rotating disk 84 and the spiral column, the weight of the rotating disk 84 and the spiral column, and the potential energy stored after its own compression. This increases the contact between the rubber ball 91 and the inner wall of the large aviation kerosene filter cylinder, causing the large aviation kerosene filter cylinder to shake, further removing the pickling solution remaining on the large aviation kerosene filter cylinder.

[0115] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
