Description

Technical Field

[0001] The utility model relates to the technical field of workpiece runout detection, in particular to a runout detection device. Background Art

[0002] At present, the main testing instruments for workpiece runout detection include runout meters, roundness meters and CMMs. Among them, the roundness meter and CMM have higher detection accuracy, but have the disadvantages of low detection efficiency and are not suitable for batch detection. Although the runout meter has higher detection efficiency, it can only detect the workpiece to be tested with the outer circle as the reference. It cannot conveniently detect the workpiece with the inner circle as the reference and which is difficult to clamp and fix. If forced detection is performed, the error will be too high and affect the detection accuracy.

[0003] Therefore, it is necessary to invent a vibration detection device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a run-out detection device, which is provided with a workpiece carrying mechanism so that when the workpiece is positioned for reference, the workpiece can be directly sleeved on the outside of the reference rod, and then the workpiece will automatically fall on the top of the reference rod under the action of gravity. At this time, the top of the inner wall of the workpiece to be measured continues to fit with the top of the reference rod.

[0029] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "above," "on," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would then be positioned "above" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0030] Figure 1 It is a schematic diagram of the overall structure of a vibration detection device according to an embodiment of the present disclosure.

[0031] like Figure 1-Figure 3 As shown, the vibration detection device disclosed in the present invention may include: a supporting base plate 1, a position adjustment mechanism 2, a workpiece mounting mechanism 3, a height adjustment mechanism 4 and a vibration detection mechanism 5 and other components.

[0032] Figure 2 It is a schematic structural diagram of a position adjustment mechanism 2 and a workpiece carrying mechanism 3 of a runout detection device according to an embodiment of the present disclosure.

[0033] like Figure 2 As shown, in the present disclosure, the position adjustment mechanism 2 includes a slide rail 21, a first limit block 22, a second limit block 23 and a sliding seat 24, wherein the slide rail 21 is fixedly arranged on the left side of the top of the support base plate 1, the first limit block 22 is fixedly arranged on one end of the top of the slide rail 21, the second limit block 23 is fixedly arranged on the other end of the top of the first limit block 22, and the sliding seat 24 is slidably nested in the horizontal direction on the outer side of the top of the slide rail 21.

[0034] Therefore, after the loading of the workpiece to be tested is completed, the T-shaped plate 31 is pushed, and then the T-shaped plate 31 slides on the outside of the slide rail 21 through the sliding seat 24. When the sliding seat 24 contacts the second limit block 23, the T-shaped plate 31 drives the workpiece to be tested to reach the detection station through the reference rod 32. After the subsequent detection is completed, the sliding seat 24 drives the T-shaped plate 31 to move left, and then the tested workpiece can be removed.

[0035] like Figure 2As shown, in a preferred embodiment, the workpiece carrying mechanism 3 includes a T-shaped plate 31 and a reference rod 32 , wherein the T-shaped plate 31 is fixedly disposed on the top of the sliding seat 24 , and the reference rod 32 passes through the T-shaped plate 31 and is fixedly connected to the T-shaped plate 31 .

[0036] Therefore, the workpiece to be measured can be sleeved on the outside of the reference rod 32 . After the workpiece is released, the workpiece falls on the top of the reference rod 32 under the action of gravity. At this time, the top of the inner wall of the workpiece contacts the top of the reference rod 32 .

[0037] Figure 3 It is a schematic structural diagram of a height adjustment mechanism 4 and a beating detection mechanism 5 of a beating detection device according to an embodiment of the present disclosure.

[0038] like Figure 3 As shown, in the present disclosure, the height adjustment mechanism 4 includes a T-shaped fixing frame 41, a locking bolt 42, a cross bar 43, a lifting plate 44, an adjusting bolt 45 and an extension plate 46, wherein the T-shaped fixing frame 41 is fixedly arranged on the top right side of the supporting base plate 1, the locking bolt 42 passes through the T-shaped fixing frame 41 and is threadedly connected to the T-shaped fixing frame 41, the cross bar 43 is rotatably sleeved on the outer end of the locking bolt 42 through a bearing, the lifting plate 44 is slidably nested in the left end of the cross bar 43 along the vertical direction, the adjusting bolt 45 passes through the cross bar 43 and is rotatably connected to the cross bar 43 through a bearing, the adjusting bolt 45 passes through the lifting plate 44 and is threadedly connected to the lifting plate 44, and the extension plate 46 is fixedly arranged on the left end of the lifting plate 44.

[0039] Therefore, when it is necessary to adjust the height of the beating detection mechanism 5, the adjusting bolt 45 is manually rotated. When the adjusting bolt 45 rotates, the lifting plate 44 is driven to rise and fall in the longitudinal slide groove at the left end of the cross bar 43. When the lifting plate 44 is lifted and lowered, the extension plate 46 drives the beating detection mechanism 5 to rise and fall synchronously, thereby completing the height adjustment of the beating detection mechanism 5.

[0040] like Figure 3 As shown, in a preferred embodiment, the jump detection mechanism 5 includes a scale indicator disk 51, a rotating shaft 52, a rotating disk 53, a torsion spring 54, a scale pointer 55 and a detection needle 56, wherein the scale indicator disk 51 is fixedly arranged at the left end of the extension plate 46, the rotating shaft 52 is rotatably nested in the middle of the front side of the scale indicator disk 51 through a bearing, the rotating disk 53 is fixedly sleeved at the outer front end of the rotating shaft 52, the torsion spring 54 is sleeved at the outer side of the rotating shaft 52 and fixedly connected between the scale indicator disk 51 and the rotating disk 53, the scale pointer 55 is fixedly arranged on the right side of the rotating disk 53, and the detection needle 56 is fixedly arranged on the left side of the rotating disk 53.

[0041] Therefore, in order to facilitate the detection needle 56 to enter the inner side of the workpiece to be measured and fit with the bottom of the inner wall of the workpiece to be measured, the workpiece to be measured located on the outside of the reference rod 32 is manually rotated. During the rotation process, the top of the inner wall of the workpiece to be measured continues to fit with the top of the reference rod 32. During the rotation of the workpiece to be measured, if there is a protrusion on the inner wall of the workpiece, the protrusion will push the detection needle 56 upward, and then the detection needle 56 drives the rotating disk 53 to rotate clockwise, and the scale pointer 55 rotates clockwise under the drive of the rotating disk 53 to display the reading. If there is a depression on the inner wall of the workpiece, the torsion spring 54 drives the rotating disk 53 to rotate counterclockwise, and the rotating disk 53 drives the detection needle 56 to enter the inner side of the depression, and at the same time drives the scale pointer 55 to rotate counterclockwise to display the reading.
