Description

Technical Field

[0001] This utility model relates to the field of thin-walled parts processing technology, specifically to a processing fixture for thin-walled parts. Background Technology

[0002] Thin-walled parts refer to structural components with significant thin-walled characteristics. Their core feature is that the wall thickness is much smaller than other major dimensions. Due to the limitations of the overall equipment weight, the application frequency of thin-walled parts is increasing. For example, a thin-walled end cap consists of an inner ring, an end cap body, and an outer ring. The inner end face and outer end face of the inner ring of the thin-walled end cap are both flat, and the inner end face and outer end face of the outer ring are both flat. As the wall thickness of the end cap decreases, thin-walled parts need to be positioned and clamped during processing.

[0003] When machining and positioning thin-walled parts, the clamping force is concentrated on a part due to the thin wall thickness, which can easily cause deformation of the part during clamping. Therefore, it does not meet the existing requirements. To address this, we propose a machining fixture for thin-walled parts. Utility Model Content

[0004] The purpose of this utility model is to provide a machining fixture for thin-walled parts, so as to solve the problem mentioned in the background art that when machining and positioning thin-walled parts, the clamping force is concentrated on a part of the part due to the thin wall thickness, which easily leads to deformation of the part during clamping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a machining fixture for thin-walled parts, including a fixed base, a central block fixed at the center of the upper surface of the fixed base, the central block being a polyhedron, and multiple electric telescopic rods detachably mounted on the outer side of the central block, the electric telescopic rods being arranged in a circular array around the axis of the fixed base, two adjusting rods being installed at the movable ends of the electric telescopic rods, and inner support positioning plates being installed at the ends of the two adjusting rods away from the electric telescopic rods.

[0006] Preferably, the surface of the fixing seat is provided with multiple pressure plate mounting slots, and the cross-section of the pressure plate mounting slots is inverted T-shaped.

[0007] Preferably, the number of pressure plate mounting slots is the same as the number of contact support rollers, and the pressure plate mounting slots are distributed in a circular array around the center of the fixed seat.

[0008] Preferably, the outer surface of the inner support positioning plate is provided with a plurality of mounting grooves, and contact support rollers are rolled on the inner side of the mounting grooves.

[0009] Preferably, the movable end of the electric telescopic rod has two positioning slots, and the inner supporting positioning plate has an adjusting groove on its surface facing the electric telescopic rod.

[0010] Preferably, the two ends of the adjusting rod are located inside the positioning slot and the adjusting slide, respectively, and both ends of the adjusting rod are rotatably inserted with anti-detachment pins. The adjusting rod is rotatably connected to the electric telescopic rod through the anti-detachment pins.

[0011] Preferably, the inner side of the adjusting slide groove is provided with two anti-detachment slide grooves, and the end of the anti-detachment pin located inside the adjusting slide groove is slidably engaged with the inner side of the anti-detachment slide groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention supports the thin-walled part from the inside using an electric telescopic rod, an inner support positioning plate, contact support rollers, and an adjusting connecting rod. The inner support positioning plate increases the force-bearing area of ​​the thin-walled part, thereby evenly distributing the force during clamping and fixing to various parts of the thin-walled part. This reduces the magnitude of the force on each part of the thin-walled part, ensuring that the Bob part will not deform after being clamped and fixed. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4As shown, a machining fixture for thin-walled parts includes a fixed base 1. The surface of the fixed base 1 has multiple pressure plate mounting slots 6. The cross-section of the pressure plate mounting slots 6 is inverted T-shaped. The number of pressure plate mounting slots 6 is the same as the number of contact support rollers 5. The pressure plate mounting slots 6 are arranged in a circular array around the center of the fixed base 1. Pressure plate components can be installed through the pressure plate mounting slots 6 to vertically restrict the thin-walled parts and prevent the thin-walled parts from vibrating vertically.

[0021] A center block 2 is fixed at the center of the upper surface of the fixed base 1. The center block 2 is a polyhedron, and multiple electric telescopic rods 3 are detachably installed on the outer side of the center block 2. The electric telescopic rods 3 are arranged in a circular array around the axis of the fixed base 1. Two adjusting rods 9 are installed at the movable ends of the electric telescopic rods 3. Inner support positioning plates 4 are installed at the ends of the two adjusting rods 9 away from the electric telescopic rods 3. The electric telescopic rods 3 are used to control the movement of the adjusting rods 9 and the inner support positioning plates 4. The arc-shaped inner support positioning plates 4 with adjustable bending angle contact the thin-walled parts from the inside, fixing thin-walled parts of different diameters from the inside and increasing the force-bearing area of ​​the thin-walled parts, thereby reducing the force on each part of the thin-walled parts and preventing deformation of the thin-walled parts during clamping.

[0022] The outer surface of the inner support positioning plate 4 is provided with multiple mounting grooves 7. Contact support rollers 5 are rolled on the inner side of the mounting grooves 7. The presence of contact support rollers 5 ensures that the rotation of the thin-walled part is not affected when it needs to rotate during the processing.

[0023] Two positioning slots 10 are provided at the movable end of the electric telescopic rod 3. An adjustment groove 8 is provided on the surface of the inner support positioning plate 4 facing the electric telescopic rod 3. The two ends of the adjustment connecting rod 9 are located inside the positioning slots 10 and the adjustment groove 8, respectively. Both ends of the adjustment connecting rod 9 are rotatably inserted with anti-detachment pins 12. The adjustment connecting rod 9 is rotatably connected to the electric telescopic rod 3 through the anti-detachment pins 12. After the inner support positioning plate 4 contacts the inside of the thin-walled part, the adjustment connecting rod 9 can rotate around the anti-detachment pins 12 connected to the electric telescopic rod 3, increasing the angle between the two adjustment connecting rods 9, so that the inner support positioning plate 4 is in complete contact with the thin-walled part.

[0024] The inner side of the adjusting slide 8 is provided with two anti-detachment slide grooves 11. The end of the anti-detachment pin 12 located inside the adjusting slide 8 is slidably engaged with the inner side of the anti-detachment slide groove 11. The presence of the anti-detachment slide groove 11 ensures that the anti-detachment pin 12 will not fall out of the inner support positioning plate 4 after being installed into the adjusting slide 8, and the end of the adjusting connecting rod 9 can slide along the length direction of the anti-detachment slide groove 11 inside the adjusting slide 8.

[0025] Working principle: When processing thin-walled parts, the thin-walled part is first placed on the surface of the fixed base 1, with the inner support positioning plate 4 located inside the thin-walled part. Then, the power supply to the device is turned on and the device is started. All electric telescopic rods 3 start simultaneously and drive the adjusting connecting rod 9 and the inner support positioning plate 4 to move towards the thin-walled part until the contact support rollers 5 on the surface of the inner support positioning plate 4 contact the inner wall of the thin-walled part. At this time, due to the limitation of the thin-walled part, as the electric telescopic rods 3 continue to move, the end of the adjusting connecting rod 9 supports the inner side of the adjusting groove 8. The positioning plate 4 slides at its end, and the angle between the two adjusting rods 9 gradually increases until the end of the adjusting rod 9 reaches the end of the adjusting groove 8. At this time, the bending angle of the inner support positioning plate 4 changes and it completely fits the inner wall of the thin-walled part. The arc-shaped inner support positioning plate 4 with an adjustable bending angle contacts the thin-walled part from the inside, fixing thin-walled parts of different diameters from the inside and increasing the force-bearing area of ​​the thin-walled part, thereby reducing the force on each part of the thin-walled part and preventing deformation of the thin-walled part during clamping.
