Description

Technical Field

[0001] The invention relates to the technical field of thin-walled metal cylinder spinning equipment, and in particular to a quick-change gasket for axial misalignment of multiple spinning wheels of a large spinning machine and a use method thereof. Background Art

[0002] Large-scale double-wheel high-power spinning machines are usually used to process large-sized thin-walled cylindrical parts, and the wheel group is one of the key components of the equipment. The axial offset of multiple wheels of large-scale spinning machines is an important method to improve the production efficiency of multiple-wheel spinning machines. The method and device of axial offset of multiple wheels is one of the key technologies for large-scale spinning machines to achieve efficient production.

[0003] The structure of the wheel group of the double-wheel spinning machine is complex and needs to withstand large multi-directional loads. In order to achieve the axial offset of multiple wheels, a complex axial offset adjustment device is often required for the large spinning machine. In order to ensure the reliability of the device, the structure of the spinning equipment, especially the wheel device, will become complicated and bulky; the outer contour of the inner wheel group of the double-wheel spinning machine cannot exceed the inner diameter range of the thin-walled cylindrical part, that is, the inner wheel group of the double-wheel spinning machine and the related frame parts are arranged inside the thin-walled cylindrical part. Due to the limitation of the internal space of the thin-walled cylindrical part, some inner wheel groups of the double-wheel spinning machines have no space to arrange the axial offset adjustment device, which brings great difficulties to the design of the spinning equipment and becomes a factor restricting the technical level of the spinning equipment. If the axial offset adjustment device is rigidly added in a limited space, the strength of the wheel device will be reduced. The complex axial offset adjustment device will increase the manufacturing cost of the spinning equipment, and the reliability of the equipment will be reduced, which will also bring some uncertain factors to the stability of the spinning equipment. Based on the above existing problems, there is an urgent need for a gasket body for the axial offset of multiple wheels of a large spinning machine. Summary of the invention

[0007] Preferably, the circular holes 7 and the U-shaped grooves 8 are alternately distributed on the semicircular gasket.

[0008] Preferably, the opening of the U-shaped groove 8 is arranged toward the center of the rotating wheel 6 and is perpendicular to the gasket slit 9 .

[0009] Preferably, the circular hole 7 is connected to the first screw 4 ; and the U-shaped groove 8 is connected to the second screw 5 .

[0022] The present invention is described in detail below in conjunction with specific embodiments. It should be noted that the following embodiments are only further descriptions of the present invention, but the protection scope of the present invention is not limited to the following embodiments.

[0023] Example

[0024] This embodiment relates to a quick-change gasket for axial misalignment of multiple rotating wheels of a large spinning machine. Figure 2-4 As shown, it is composed of two symmetrical semicircular gasket bodies 3; wherein, a circular hole 7 and a U-shaped groove 8 are arranged on the semicircular gasket body 3; the circular holes 7 and the U-shaped grooves 8 are alternately distributed on the semicircular gasket. The present invention arranges a circular hole 7 on the semicircular gasket body 3 to prevent the gasket body 3 from moving outward during spinning, thereby ensuring the safety and reliability of the gasket body during spinning; the arranged U-shaped groove 8 can quickly take out or put in the gasket body 3 without removing the second screw 5, thereby reducing the disassembly and assembly process, that is, the gasket can be quickly replaced without removing the rotating wheel, and the precise axial misalignment of multiple rotating wheels can be achieved by adjusting the thickness of the gasket group. The size of the circular hole 7 is: Φ=18mm. The width of the U-shaped groove 8 is 18mm. The center of the end arc R9 of the U-shaped groove 8 coincides with the center of the screw hole.

[0025] See Figure 1As shown, the gasket body 3 is processed into a combination of gaskets of different thicknesses (the thickness of the gasket body 3 is 1, 2, 5, 10 or 15 mm), and the thickness value and quantity of each gasket can be selected according to the actual adjustment requirements of spinning, so that the precise axial offset of the multi-wheel required during spinning can be conveniently achieved by adjusting the number of gaskets, that is, adjusting the total thickness of the gaskets. The gasket body 3 can be taken out or put in without removing the second screw 5 in the U-shaped groove 8, that is, the gasket body 3 can be conveniently and quickly replaced without removing the spinning wheel 6, so that the precise axial offset of the multi-wheel during spinning can be achieved by adjusting the number of gasket bodies 3, that is, the thickness, to meet the process requirements of multi-wheel spinning, and the precise distance of the axial offset of the multi-wheel is guaranteed by the precisely processed thickness of the gasket body 3, that is, S1 = t1-t2, S2 = t2-t3.

[0026] See Figure 2 As shown, during installation, the rotating wheel shaft 2 is installed inside the rotating wheel seat 1 through bearings, etc., the rotating wheel shaft 2 extends out of the shaft end for installing the rotating wheel 6, and a gasket body 3 for adjusting the rotating wheel position is installed between the shaft shoulder of the rotating wheel shaft 2 and the rotating wheel 6, and the first screw 4 and the second screw 5 are used to fix the rotating wheel 6 and press the gasket body 3.

[0027] During removal, since the gasket body 3 is composed of two symmetrical semicircular gaskets, the gasket body 3 is divided into two halves along the gasket cut slit 9 and is symmetrically arranged, and its first screw 4 is correspondingly connected to the circular hole 7, and the second screw 5 is correspondingly connected to the U-shaped groove 8; remove the first screw 4, and only loosen the second screw 5 to create a gap for convenient removal of the gasket body 3, and the gasket body 3 can be taken out or put in.

[0028] The quick-change gasket for axial misalignment of multiple rotating wheels of a large-scale spinning machine involved in the present invention has the characteristics of being able to be quickly replaced and achieving reliable and precise misalignment. Compared with the complex equipment structure specially provided with an axial misalignment adjustment device, it has a simple structure and low manufacturing cost. It uses a simple structure and a clever method to achieve precise axial misalignment of multiple rotating wheels and rapid adjustment of the axial misalignment distance, and can effectively improve the work efficiency of axial misalignment adjustment of spinning processing equipment.

[0029] The gasket body 3 of the present invention may also be a split multi-petal structure, and circular holes 7 and U-shaped grooves 8 are also provided on the gasket body 3; the circular holes 7 and U-shaped grooves 8 are alternately distributed on the gasket body 3. The present invention may also be applicable to other similar devices that require adjusting the position of the rotary wheel.

[0030] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
