AI Technical Summary
The prior art lacks reliable methods to detect the clearance of the piston compressor at the maximum stroke, resulting in the inability to ensure that the distance between the piston and the steel surface of the compressor meets the standards, affecting the performance of the compressor.
A piston compressor gap detection tool is designed, including a gap detector installed at the piston cylinder of the compressor housing. The detector consists of a bottom shell, a dial meter and a shell cover, and is equipped with a gap detection probe. The gap between the piston and the steel surface is measured by the displacement of the probe, and the results are displayed on the dial meter.
Through this detection tool, the gap between the piston at the maximum stroke and the steel surface of the compressor can be easily measured, ensuring that the gap meets the standards, thereby improving the performance and reliability of the compressor.

Technical Field
[0001] The utility model relates to the technical field related to compressors, in particular to a clearance detection tool for piston compressors. Background Art
[0002] During compressor movement, the piston must not be too far above the steel surface, otherwise it will hit the valve plate and cause damage. It must also not be too low, otherwise the stroke will be shortened, insufficient work will be produced, and performance will be affected. Therefore, after installing the piston, there is no reliable technical solution to check whether the clearance at the highest point of the piston meets the standard. Utility Model Content
[0003] The purpose of this application is to provide a piston compressor clearance detection tool to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a piston compressor clearance detection tool, comprising a clearance detector installed at the piston cylinder of the compressor housing to detect the clearance of the piston in the piston cylinder, the clearance detector comprising a bottom shell, a dial indicator and a shell cover, the dial indicator being installed on the shell cover, the dial indicator being provided with a clearance detection probe, the clearance detection probe extending to the outside of the shell cover, the shell cover being fixedly installed on the bottom shell, and the bottom shell being a disc-like shape with a fan-shaped notch.
[0005] Preferably, a handle integrally connected to one side of the bottom shell is fixedly mounted thereon.
[0006] Preferably, the bottom shell, shell cover and handle are all made of stainless steel.
[0007] Above, the technical effects and advantages of the utility model are:
[0008] In the utility model, the bottom shell is buckled onto the outside of the piston cylinder, and then the stator of the driving piston is rotated so that the piston reaches the maximum stroke. The clearance detection probe extends out and contacts the upper surface of the piston. In this way, the displacement of the clearance detection probe is the clearance between the piston and the steel plate surface of the compressor. The clearance is displayed on the dial of the dial indicator, which is convenient for measurement. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0014] In the description of the present disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "top," "bottom," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present disclosure and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0015] It should also be noted that the standard parts used in this application document can all be purchased from the market, and can be customized according to the description in the specification and drawings. Unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to the specific circumstances, and, in the absence of clear limitations, machines, parts, and equipment can all adopt conventional models in the prior art.
[0016] In this document, the term "comprising" is intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.
[0017] Example: Reference Figure 1-2 The piston compressor clearance detection tool shown includes a clearance detector 3 installed at the piston cylinder 2 of the compressor housing 1 to detect the clearance of the piston in the piston cylinder 2. The clearance detector 3 includes a bottom shell 4, a dial indicator 5 and a shell cover 7. The dial indicator is installed on the shell cover 7. The dial indicator is provided with a clearance detection probe 6. The clearance detection probe 6 extends to the outside of the shell cover 7. The shell cover 7 is fixedly installed on the bottom shell 4. The bottom shell 4 is a disc-like shape with a fan-shaped notch, so that the position of the piston can be observed through the fan-shaped notch. During installation, the device is first placed on a plane so that the bottom of the clearance detection probe 6 is flush with the lower surface of the bottom shell. At this time, the dial indicator returns to 0, which is a calibration operation. The bottom shell of the device is then buckled onto the outer surface of the piston cylinder. At this time, the clearance detection probe is extended, and then the stator that drives the piston is rotated so that the piston reaches the maximum stroke. The clearance detection probe extends and contacts the upper surface of the piston. In this way, the displacement of the clearance detection probe is the clearance from the piston to the compressor steel plate surface, and the clearance data is displayed on the dial indicator for viewing.
[0018] With the above structure, a handle 8 integrally connected to the bottom shell 4 is fixedly mounted on one side of the bottom shell 4, and the handle is convenient for carrying the device.
[0019] According to the above structure, the bottom shell 4, the shell cover 7 and the handle 8 are all made of stainless steel.
