Detailed Description
The invention discloses a free roller outer diameter detection tool which can be used for rapidly detecting the outer diameter of a free roller.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, the terms "upper", "lower", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention but do not require that the present invention must be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The free roller outer diameter detection tool comprises a detection support leg 1 and a handle 2. The length of the detection foot 1 is greater than half the set dimension of the free roll outer diameter. The number of the detection legs 1 is two, and the dimension between the inner side surfaces of the two detection legs 1 is the minimum allowable dimension of the outer diameter of the free roller. The handle 2 is used for connecting the two detection support legs 1 and is convenient for a person to hold. The upper ends of the two detection support legs 1 are connected to the handle 2.
The "inner side surfaces of the two detection legs 1" mean two opposing surfaces of the two detection legs 1. The "minimum allowable dimension of the outer diameter of the free roller" is calculated from the design dimension of the outer diameter of the free roller and the allowable wear deviation.
The method for detecting by using the free roller outer diameter detection tool comprises the following steps: the handle 2 is held by hand, and the two detection feet 1 are inserted into the two sides of the free roller from the top to the bottom, if the two detection feet 1 can pass through the half position of the free roller, which indicates that the actual outer diameter dimension of the free roller at the position is smaller than the minimum allowable dimension of the outer diameter of the free roller, then the free roller is unqualified, as shown in the attached figure 3.
If the two detection feet 1 cannot pass the position of half of the free roller, it is shown that the actual outer diameter dimension of the free roller at this position is larger than the minimum allowable dimension of the outer diameter of the free roller, and the actual outer diameter dimension of the free roller at this position is qualified, as shown in fig. 4. In the inspection, two or three points are inspected in the axial direction of the free roller, in general. If all the detection points are qualified, the free roller is qualified, and the assembly can be carried out. If one detection point is unqualified, the free roller is not qualified, and the assembly cannot be carried out.
The free roller outer diameter detection tool can be used for rapidly detecting the free roller and checking out unqualified free rollers, so that the arc alignment difficulty in assembly is simplified, and the water leakage frequency is reduced.
It should be noted that the length of the detection leg 1 is greater than half of the design size of the outer diameter of the free roller, so that the detection leg 1 is not hindered from passing the half of the free roller by the interference of the handle 2 with the free roller when the actual size of the outer diameter of the free roller is smaller than the minimum allowable size of the outer diameter of the free roller.
The specific structures of the detection leg 1 and the handle 2 are as follows: two detection legs 1 are respectively arranged at two ends of the handle 2. The two detection legs 1 and the handle 2 form a corner part, or the two detection legs 1 and the handle 2 form an inverted U-shaped structure.
The outside of the corner formed by the detection leg 1 and the handle 2 is provided with an outside chamfer 4, thus avoiding the outside of the corner from scratching the free roller. In addition, an inner chamfer 5 part is arranged on the inner side of the corner part, so that the inner side of the corner part is prevented from scratching the free roller.
Since the detection tool needs to be frequently in frictional contact with the free roller, the surface of the detection tool needs to have high hardness. Therefore, the surface of the detection tool is subjected to quenching treatment.
In order to improve the detection precision of the detection tool, the inner side surface of the detection support leg 1 is limited to be in narrow-surface contact with the free roller. The width of the inner side of the detection foot 1 is between 18-22 mm.
In order to facilitate the hand to grasp the handle 2, the handle 2 is provided with a hand holding hole. The hand-held hole penetrates the handle 2 in the thickness direction of the handle 2. The handle 2 can be gripped by the hand through the hand holding hole.
Further, the hand holding hole is a long hole 3, and the long hole 3 is arranged along the length direction of the handle 2. The elongated hole 3 not only ensures that a human hand can freely pass through the elongated hole 3, but also reduces the weight of the handle 2. The longitudinal direction of the elongated hole 3 is a direction from one detection leg 1 to the other detection leg 1.
In an embodiment of the present invention, the length of the elongated hole 3 is set to about 120 mm. The cross section of the detection support leg 1 is made of square steel with the side length of 22 mm.
Finally, it should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
