Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these technical solutions are only used for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. And can be modified as needed by those skilled in the art to suit particular applications.
First embodiment
As shown in fig. 2, the guide shaft support of the present invention includes a base 1, which is preferably circular, a shaft support portion 2, and two fastening arm portions 3. The number of the fastening arm portions 3 is not particularly limited when the function of the fastening arm portions 3 is not affected, and the number of the fastening arm portions 3 is two in the present embodiment. The form of the base 1, the shaft support 2, and the fastening arm 3 is not particularly limited as long as the function of the guide shaft support is not impaired, and may be any of welding, integral molding casting, and screwing, and in the present embodiment, the base 1, the shaft support 2, and the two fastening arms 3 are preferably integrally molded.
The base 1 is mounted and fixed on a receiving member, not shown, for providing a fixed support for the shaft supporting portion 2. The base 1 is provided with the mounting hole 11, and the position of the mounting hole 11 is not particularly limited, but in the present embodiment, the mounting hole 11 is preferably provided at a position symmetrical with respect to the axis of the guide shaft through hole 21 of the shaft support portion 2, which will be described below, so that the force generated by the rotational vibration of the guide shaft 5 during operation can be uniformly transmitted to the portion of the mounting hole 11 without affecting the stability of the base 1 and thus the guide shaft support.
The position of the shaft support portion 2 is not particularly limited as long as the function of the shaft support portion 2 for positioning the guide shaft 5 is not affected, but in the present embodiment, the shaft support portion 2 is preferably formed to protrude from the middle portion of the base 1, the shaft support portion 2 is preferably formed with a guide shaft through hole 21, the guide shaft through hole 21 and the shaft support portion 2 are preferably coaxially provided, and as schematically shown in fig. 2, the guide shaft 5 is inserted through the guide shaft through hole 21 and rotates in the guide shaft through hole 21 during operation.
The edge of the guide shaft through hole 21 is provided with the notch 22, and the notch 22 can effectively buffer the acting force of the guide shaft 5 in the vibration process, reduce the deformation of the shaft supporting part 2 and ensure the stability of the guide shaft support.
The length of the notch 22 is not particularly limited, and it is preferable that the notch 22 is provided to extend from the edge of the guide shaft through hole 21 to the connecting portion of the shaft support portion 2 and the base 1, and the length of the notch 22 is set to be long, as shown in fig. 2, so that the force applied during the vibration of the guide shaft 5 can be more effectively absorbed by the long-distance notch.
If necessary, the length and extending direction of the notch 22 may be adjusted so that the notch 22 is formed only partially at the edge of the guide shaft through hole 21 and does not penetrate therethrough.
Specifically, in the present embodiment, the length of the notch 22 is described by taking as an example that the notch 22 extends in the axial direction of the shaft support 2, and the length of the notch 22 is set in at least the following three ways:
first, the notch 22 is flush with the upper surface of the guide shaft through hole 21 only;
secondly, the notch 22 is only flush with the lower surface of the guide shaft through hole 21;
thirdly, the notch 22 extends from the middle portion of the outer wall of the shaft support portion 2, that is, the notch 22 is not flush with the upper surface of the guide peripheral through hole 21 nor with the lower surface of the guide shaft through hole 21.
The upper and lower surfaces of the shaft support 2 are parallel to each other, and when viewed from above, the hole edge of the guide shaft through hole 21, which is continuous with the upper surface of the shaft support 2, is located on the same surface as the upper surface of the shaft support 2, and the upper surfaces of the shaft support 2 and the guide shaft through hole 21 are flat.
The two fastening arm sections 3 extend from the notches 22 and face each other. Fixing holes 31 through which the screws 4 are inserted are provided at one ends of the two fastening arm portions 3 remote from the notches 22, respectively, and the two fixing holes 31 face each other. The screw 4 may be any screw member capable of fastening the guide shaft 5, and in the present embodiment, a screw and a nut are preferable, and the distance between the two fastening arm portions 3 can be adjusted by engagement between the screw inserted through the fixing hole 31 and the nut fitted around the screw. Specifically, when the distance between the two fastening arm portions 3 is too large, the screw 4 is tightened to reduce the distance between the fastening arm portions 3, and when the distance between the two fastening arm portions 3 is too small, the screw 4 is loosened to increase the distance between the fastening arm portions 3. Here, too large a distance between the fastening arm portions 3 means that the gap between the fastening arm portions 3 is not sufficiently tightened to fasten the guide shaft 5, and too small a distance between the fastening arm portions 3 means that too small a gap between the fastening arm portions 3 hinders the operation of the guide shaft 5. In the present embodiment, the arm part 3 is preferably provided in a lever type configuration, and even if the contact area between the shaft support part 2 and the base 1 is small, the stability of the guide shaft support and the guide shaft 5 penetrating the guide shaft through hole 21 can be ensured by tightening the shaft support part 2 with the arm part 3.
Preferably, as shown in fig. 2, the distance between the two fixing holes 31 is greater than the width of the notch 22, so that the screw member 4, such as a screw and a nut, passing through the fixing holes 31 has a greater adjustment range, and more convenient adjustment is achieved.
The thickness of the guard arm portion 3 is not particularly limited, and preferably, as shown in fig. 2, the thickness of at least one guard arm portion 3 is set to become gradually smaller as it extends outward from the notch 22. Since the tightening arm portion 3 near the notch 22 is subjected to the greatest force and the tightening arm portion 3 far from the notch 22 is subjected to the least force, the thickness of the tightening arm portion 3 is set to gradually decrease as it extends outward from the notch 22, thereby achieving material saving without affecting the force.
Preferably, the slit 12 is provided at a position where the edge of the base 1 faces the fastening arm portion 3, and the length of the slit 12 is not particularly limited, but in the present embodiment, the length of the slit 12 preferably extends from the edge of the base 1 to a connecting portion between the shaft support portion 2 and the base 1, and the slit 12 can absorb stress applied to the base 1 when the fastening arm portion 3 is adjusted by the screw 4, thereby preventing deformation of the base 1.
Second embodiment
The second embodiment differs from the first embodiment in the shape of the base 1, and as shown in fig. 3, in the present embodiment, the base 1 is elliptical. The base 1 may be formed in various shapes in combination with actual conditions, and the description of the same portions as those of the first embodiment will be omitted.
So far, the technical solutions of the present invention have been described with reference to the accompanying drawings, but it is obvious to those skilled in the art that the scope of the present invention is not limited to these specific technical solutions. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
