Description

Technical Field

[0001] This utility model relates to the field of vibration measurement technology, specifically to a vibration measurement vacuum tank protection component. Background Technology

[0002] Vibration measurement is an important tool for equipment condition monitoring and fault diagnosis. When measuring vibration of workpieces with special requirements, such as bearing assemblies, testing must be conducted in a vacuum environment. Vibration can effectively reflect the comprehensive operating characteristics of a bearing unit.

[0003] In existing technologies, such as the Chinese patent with publication number CN215811633U entitled "A Vibration Testing Device for a Bearing Unit," the disclosed technical solution describes that after the workpiece to be tested is installed on the worktable, a vacuum chamber is placed on the outside to form a sealed space. Air is then extracted from the vacuum chamber using a vacuum suction device to create a vacuum with a vacuum degree <10 Pa. To more realistically simulate the working conditions of workpieces, such as bearings, the equipment sometimes needs to be placed flat or upside down. Under good sealing conditions and atmospheric pressure, the vacuum chamber and the worktable are tightly connected, and the vacuum chamber will not fall off when the equipment is upside down or flat. However, as the testing time increases, the vacuum degree inside the vacuum chamber gradually decreases. When the equipment is upside down or flat, the vacuum chamber may fall off and break, reducing its service life. Utility Model Content

[0004] This invention provides a vibration measurement vacuum tank protection component to solve the above-mentioned problems.

[0005] The present invention adopts the following technical solution: a vibration measuring vacuum tank protective component, including a protrusion and a pressure plate;

[0006] Multiple protrusions are provided and symmetrically distributed on both sides of the vacuum tank body; the protrusions are fixed on the outer wall of the vacuum tank body.

[0007] Multiple pressure plates are symmetrically distributed on the outside of the vacuum tank body, positioned between the worktable and the protrusions. The pressure plates are movable on the worktable along the axis of the vacuum tank body via elastic connectors. The pressure plates abut against the protrusions under the elastic force of the connectors. This protects the vacuum tank body on the worktable, preventing it from falling off the worktable when the equipment is inverted or laid flat, as the vacuum level inside the vacuum tank gradually decreases.

[0008] Furthermore, a groove is provided on the end wall of the pressure plate near the protrusion; the groove and the protrusion are interlocked. This reduces the probability of the vacuum tank body shaking due to vibration and improves the protection effect on the vacuum tank body.

[0009] Furthermore, the elastic connector includes a mating hole and a connecting rod; the mating hole is a through hole opened on the pressure plate; the connecting rod is inserted into the mating hole and slides in fit with the mating hole; the connecting rod is fixedly connected to the worktable; a compression spring is connected between the connecting rod and the pressure plate.

[0010] Furthermore, the mating hole is an elongated slot extending radially along the body of the vacuum canister. When it is necessary to install or remove the vacuum canister body, pull the pressure plate away from the vacuum canister body to avoid the protrusion, so as to facilitate the installation or removal of the vacuum canister body.

[0011] Furthermore, a limiting block is provided on the side of the pressure plate away from the vacuum tank body; the limiting block is fixed to the worktable, and a protrusion is fixed on the limiting block; the protrusion and the side wall of the pressure plate away from the vacuum tank body abut against each other. During testing, the limiting block and the protrusion restrict the pressure plate from moving radially along the vacuum tank body. When it is necessary to install or remove the vacuum tank body, first move the pressure plate away from the worktable, past the protrusion, and then pull the pressure plate away from the vacuum tank body to avoid the protrusion, so as to facilitate the installation or removal of the vacuum tank body.

[0012] Furthermore, a washer is slidably mounted on the pressure plate; the washer and the compression spring are fixedly connected.

[0013] The beneficial effects are:

[0014] 1. The pressure plate abuts against the protrusion under the elastic force of the elastic connector. This protects the vacuum tank body on the worktable, preventing it from falling off the worktable as the vacuum level inside the vacuum tank gradually decreases when the equipment is inverted or laid flat.

[0015] 2. Groove and protrusion insertion. This reduces the chance of the vacuum tank body shaking due to vibration and improves the protection of the vacuum tank body. When it is necessary to install or remove the vacuum tank body, first move the pressure plate away from the worktable, past the protrusion, and then pull the pressure plate away from the vacuum tank body to avoid the protrusion, so as to facilitate the installation or removal of the vacuum tank body.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0024] An embodiment of the vibration measuring vacuum tank protection component of this utility model is as follows: Figures 1 to 5 As shown, the device includes protrusions 300 and pressure plates 400. Multiple protrusions 300 are symmetrically distributed on both sides of the vacuum tank body 200. The protrusions 300 are fixed to the outer wall of the vacuum tank body 200. Multiple pressure plates 400 are symmetrically distributed on the outer side of the vacuum tank body 200 and positioned between the worktable 100 and the protrusions 300. The pressure plates 400 are movably mounted on the worktable 100 along the axial direction of the vacuum tank body 200 via elastic connectors. The pressure plates 400 abut against the protrusions 300 under the elastic force of the elastic connectors. This protects the vacuum tank body 200 on the worktable 100, preventing it from falling off the worktable 100 as the vacuum level inside the vacuum tank gradually decreases when the equipment is inverted or laid flat. A groove 410 is provided on the end wall of the pressure plate 400 near the protrusions 300; the groove 410 and the protrusions 300 are inserted into each other. This reduces the likelihood of the vacuum tank body 200 shaking due to vibration, thus improving the protection of the vacuum tank body 200.

[0025] The elastic connector includes a mating hole 420 and a connecting rod 500. The mating hole 420 is a through hole formed on the pressure plate 400. The connecting rod 500 is inserted into the mating hole 420 and slides in contact with it. The connecting rod 500 is fixedly connected to the worktable 100. A compression spring 510 connects the connecting rod 500 and the pressure plate 400. A washer 520 is slidably mounted on the pressure plate 400. The washer 520 is fixedly connected to the compression spring 510. The mating hole 420 is an elongated slot extending radially along the vacuum tank body 200. When it is necessary to install or remove the vacuum tank body 200, the pressure plate 400 is pulled away from the vacuum tank body 200 to avoid the protrusion 300, so as to facilitate the installation or removal of the vacuum tank body 200. A limiting block 600 is provided on the side of the pressure plate 400 away from the vacuum tank body 200; the limiting block 600 is fixed on the worktable 100, and a protrusion 610 is fixed on the limiting block 600; the protrusion 610 and the side wall of the pressure plate 400 away from the vacuum tank body 200 abut against each other. During testing, the limiting block 600 and the protrusion 610 restrict the pressure plate 400 from moving radially along the vacuum tank body 200. When it is necessary to install or remove the vacuum tank body 200, first move the pressure plate 400 away from the worktable 100, past the protrusion 610, and then pull the pressure plate 400 away from the vacuum tank body 200 to avoid the protrusion 300, so as to facilitate the installation or removal of the vacuum tank body 200.

[0026] Based on the above embodiments, the working principle and process of this utility model are as follows: During testing, after the workpiece to be tested is installed on the workbench 100, the pressure plate 400 is pulled away from the vacuum chamber body 200 to avoid the protrusion 300, so that the vacuum chamber body 200 can be covered to form a sealed space around the workpiece. Then, the pressure plate 400 is pushed towards the vacuum chamber body 200, and the protrusion 300 is engaged in the groove 410. After releasing the pressure plate, the pressure plate 400 presses against the protrusion 300 under the action of the compression spring 510. At this time, the protrusion 610 and the side wall of the pressure plate 400 away from the vacuum chamber body 200 abut against each other. Then, the air in the vacuum chamber is extracted by the vacuum suction device to form a vacuum. When the equipment is inverted or laid flat, the pressure plate 400, the protrusion 300, and the protrusion 610 are in a limiting fit to prevent the vacuum level inside the vacuum chamber body from gradually decreasing and falling off the workbench 100.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
