Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of snap ring detection, in particular to a precision snap ring detection device. Background Art
[0002] A snap ring is an annular stopper installed on the edge of a shaft or bearing to prevent the shaft or bearing from sliding out axially. A groove is cut on the edge of the shaft or bearing and the snap ring is made of spring steel and is embedded in the groove using elasticity.
[0003] At present, some existing precision snap ring detection devices detect the size of the snap ring by placing the snap ring on the surface of the column to check the inner diameter of the snap ring, and measuring the outer diameter of the snap ring with a measuring tool, so as to check whether the size and error of the snap ring meet the qualification requirements. However, since the size of the column is relatively fixed, different columns need to be replaced when snap rings of different sizes need to be detected, which is relatively inconvenient to use. Therefore, we propose a precision snap ring detection device to solve or improve the above problems. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention provides a precision snap ring detection device, which solves the problems mentioned in the above background.
[0005] The utility model provides the following technical solution: it includes a base, a column fixed on the top of the base, a support column fixed on the surface of the base, a first limit column fixed to the inside of the column, a spring sleeved on the surface of the first limit column, a limit plate sleeved on the surface of the first limit column, a support plate fixed on the surface of the limit plate, a first indicator plate fixed on the top of the limit plate, a snap ring sleeved on the surface of the support plate, and arranged on the top of the support column, so that the outer diameter of the snap ring can be measured.
[0006] Furthermore, the measuring assembly includes a fixed box fixed to the top of the support column, a second limiting column fixed inside the fixed box, a slider sleeved on the surface of the second limiting column, a connecting rod fixed to the surface of the slider, a contact block fixed to the top of the connecting rod, and a second indicator plate fixed to the surface of the slider.
[0007] Furthermore, a plurality of groups of first limiting posts are symmetrically fixed inside the base, and the number of springs is the same as the number of the first limiting posts.
[0008] Furthermore, a placement groove is provided on the surface of the support plate, and the clamping ring is located inside the limiting groove provided on the surface of the support plate.
[0009] Furthermore, one end of the first limiting column passes through the interior of the support plate and is slidably connected to the support plate.
[0010] Compared with the prior art, the present invention has the following beneficial effects: by arranging the support plate and the spring, the support plate can be squeezed when the snap ring is sleeved on the surface of the support plate so that the support plate moves toward the side close to the inside of the column; when the snap ring moves to the placement groove opened on the surface of the support plate, the spring will push the support plate to move so that the support plate contacts the surface of the snap ring, thereby achieving adaptation to snap rings of different sizes, so that there is no need to replace columns of different sizes when testing snap rings of different sizes, and it is relatively convenient to use.

One end of the support plate 4 is located outside the column 2 and the support plate 4 can move inside the column 2. When the support plate 4 moves, it will drive the fixed limit plate 14 to move. The limit plate 14 can adjust the position of the support plate 4. The position is restricted to prevent the support plate 4 from detaching from the inside of the column 2. One end of the first limiting column 12 passes through the inside of the support plate 4 and is slidably connected to the support plate 4. Two groups of first limiting columns 12 are inserted into the interior of a group of support plates 4. The first limiting columns 12 can limit the position of the support plate 4, reduce or prevent the support plate 4 from tilting itself when moving, and improve the stability of the support plate 4 when moving. A placement groove is provided on the surface of the support plate 4. The first indicator plate 6 is fixed to the top of the limiting plate 14. The number of the first indicator plates 6 is the same as the number of the limiting plates 14. The top of the base 1 is provided with a slot for the first indicator plate 6 to move. When the limiting plate 14 moves, it will drive the fixed first indicator plate 6 to move. A scale line is provided on the top of the column 2. The first indicator plate 6 cooperates with the scale line to facilitate personnel to observe the moving distance of the limiting plate 14. The snap ring 3 is sleeved on the surface of the support plate 4. The snap ring 3 is located inside the limiting grooves provided on the surfaces of several groups of support plates 4.

The slider 5 can move inside the fixed box 9 through the second limiting column 15. Both groups of second limiting columns 15 pass through the interior of the slider 5 and are slidably connected to the slider 5. The second limiting column 15 can limit the position of the slider 5 to prevent the slider 5 from tilting when moving, thereby improving the stability of the slider 5 when moving. A handle is fixed on the top of the slider 5, and a handle is provided on the top of the fixed box 9. The movable slot can drive the slider 5 to move by moving the handle. The connecting rod 11 is fixed on the surface of the slider 5. When the slider 5 moves, the fixed connecting rod 11 will move. The contact block 8 is fixed on the top of the connecting rod 11. When the connecting rod 11 moves, the fixed contact block 8 will move. One side of the contact block 8 is in contact with the surface of the retaining ring 3.

[0020] Working principle: when the size of the snap ring 3 needs to be tested, the snap ring 3 is placed on the surface of the support plate 4. At this time, the snap ring 3 will squeeze the support plate 4 to make the support plate 4 move to the side close to the inside of the column 2. When the snap ring 3 moves to the placement groove opened on the surface of the support plate 4, the spring 13 will push the limit plate 14 to move, so that the limit plate 14 drives the support plate 4 to move and makes the support plate 4 contact with the surface of the snap ring 3, thereby fixing the snap ring 3 relatively to the inside of the placement groove opened on the surface of the support plate 4, thereby realizing the adaptation of snap rings 3 of different sizes. When testing snap rings 3 of different sizes, there is no need to replace columns 2 of different sizes, and the same For convenience, the support plate 4 has moved and driven the limit plate 14 to move. The limit plate 14 will drive the first indicator plate 6 to move. The inner diameter of the snap ring 3 can be measured through the first indicator plate 6 and the scale line. When the outer diameter of the snap ring 3 needs to be measured, the slider 5 is pushed to move, so that the slider 5 drives the connecting rod 11 to move. When the connecting rod 11 moves, it drives the contact block 8 to move, so that the contact block 8 moves to one side of the snap ring 3 and contacts the surface of the snap ring 3. At this time, the outer diameter of the snap ring 3 can be measured by observing the second indicator plate 10 and the scale line and coordinating with the first indicator plate 6 and the scale line, thereby completing the detection of the snap ring 3.
