Description

Technical Field

[0001] The utility model belongs to the technical field of fixtures and tools, and in particular relates to a fixture and tool for measuring a graduated rotary cylinder. Background Art

[0002] There is a threaded groove on the outer wall of the scale cylinder. Generally, when measuring the parameters on the threaded groove, the scale cylinder is manually held. However, when held manually, the measurement is inaccurate due to slight shaking. Later, through improvements, a clamp is used to clamp the two ends of the scale cylinder, and the scale cylinder is rotated for measurement. When clamping the scale cylinder, this method generally adopts abutment clamping of the two end surfaces of the scale cylinder. During the measurement process, if the operator accidentally applies too much pressure on the scale cylinder, it will cause the scale cylinder to tilt, affecting the measurement accuracy.

[0003] Therefore, it is necessary to design a fixture for measuring a graduated rotary cylinder to solve the technical problem in the prior art that the graduated rotary cylinder is prone to tilt when the two end surfaces thereof are abutted and clamped, thereby affecting the measurement accuracy.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] In this document, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or that a third component may be interposed between the first component and the second component. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe technical content.

[0045] As used herein, when an element or layer is referred to as being "located on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it may be directly located on, engaged, connected, attached to, or coupled to the other element or layer, or there may be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly engaged to," "directly connected to," "directly attached to," or "directly coupled to" another element or layer, there may be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0046] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." when following a list of elements modify the entire list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0047] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an" and "the" may also be intended to include plural forms, unless otherwise clearly indicated herein. The terms "comprise", "include" and "have" are inclusive and therefore specify the presence of features, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components and / or combinations thereof.

Additional or alternative steps may be adopted.

[0048] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects, or designs. Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0049] Research has found that there is a threaded groove on the outer wall of the scale cylinder. Generally, when measuring the parameters on the threaded groove, the scale cylinder is manually held. However, when held manually, slight shaking may lead to inaccurate measurements. Later, through improvements, a clamp was used to clamp the two ends of the scale cylinder, and the scale cylinder was rotated for measurement. When clamping the scale cylinder, this method generally uses abutment clamping on the two end surfaces of the scale cylinder. During the measurement process, if the operator accidentally applies too much pressure on the scale cylinder, it will cause the scale cylinder to tilt, affecting the measurement accuracy.

[0050] Based on the above research, an embodiment of the present disclosure provides a fixture for measuring a scale cylinder. By providing a locking mechanism, one end of the scale cylinder is fixed by using a locking piece corresponding to the gear teeth on the inner wall of the scale cylinder, and then the other end of the scale cylinder is inserted by using an abutment mechanism, so that the scale cylinder remains stationary and during the measurement process, no matter whether the operator increases or decreases the force applied to the scale cylinder, the scale cylinder cannot be tilted, thereby improving the measurement accuracy.

[0051] The defects in the above solutions are the results obtained by the utility model inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article should be the contributions made by the utility model inventor to the present invention during the disclosure process.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0053] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0054] In some embodiments, as Figure 1 and Figure 2 As shown, before measurement, the positioning sleeve 13 is inserted into the first clamping block 10. At this time, the positioning groove 130 is adjusted to keep it in a vertical state. Then the tightening bolt 11 is manually rotated. When the lower end face of the tightening bolt 11 abuts against the outer wall of the positioning sleeve 13, the positioning sleeve 13 can be fixed inside the first clamping block 10. At this time, the end of the scale drum 3 with the gear teeth 30 is sleeved on the outside of the locking block 12 along the F1 direction, so that the locking member 120 is locked in the gear teeth 30, which can realize the limitation of one end of the scale drum 3. In order to make the scale drum 3 smoothly inserted into the locking block 12, the negative tolerance between the outer diameter of the locking block 12 and the inner diameter of the scale drum 3 is 5-10 wires.

[0055] In some embodiments, as Figure 3 and Figure 4 As shown, when one end of the scale drum 3 is limited, the plug rod 22 is manually pulled to make it slide in the connecting sleeve 21. At this time, the reset spring 24 is compressed. After the scale drum 3 is placed horizontally, the plug rod 22 is released, and the reset spring 24 rebounds and resets along the F2 direction, and the connecting bolt 23 is inserted into the inner wall of the other end of the scale drum 3, and the end face of the annular gasket 25 abuts against the end face of the scale drum 3. At this time, the rebound force of the reset spring 24 is used to keep the scale drum 3 horizontal and stationary, and the two ends of the scale drum 3 are respectively inserted by the clamping block 12 and the connecting bolt 23. During the measurement process, even if the scale drum 3 is subjected to excessive external pressure, it can remain horizontal, and due to the clamping of the clamping piece 120 and the gear 30, it can be ensured that the scale drum 3 will not rotate during the measurement process and affect the measurement.

[0056] In the description of the embodiments of the present invention, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0057] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, terms such as "first", "second" and other numerical terms do not imply an order or sequence when used herein unless expressly indicated above. Therefore, without departing from the teachings of the example embodiments, the first element, component, region, layer or section discussed above may be referred to as a second element, component, region, layer or section.

[0058] Spatially relative terms, such as "inside," "outside," "below," "beneath," "down," "above," "on," etc., may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as being "below" or "below" other elements or features will be oriented to be "above" the other elements or features. Thus, the example term "below" may encompass both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0059] In the above discussion, unless otherwise indicated, the terms "about," "approximately," "substantially," etc., when used to describe a numerical value, mean a variation of + / - 10% of the value.

[0060] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
