Description

Technical Field

[0001] This utility model relates to the field of rubber ring centroid offset position measurement technology, and in particular to a device that can measure the centroid offset position of a rubber ring. Background Technology

[0002] A rubber ring is an annular cover composed of one or more parts, fixed to one ring or washer of a bearing and contacting or forming a narrow labyrinth gap with another ring or washer to prevent lubricating oil leakage and foreign matter intrusion. During the production process, the center-of-gravity offset of the rubber ring needs to be measured. Existing measurement methods mostly rely on manual labor. In mass production, measuring the center-of-gravity offset of the rubber ring is time-consuming, labor-intensive, and inefficient. Therefore, a device capable of measuring the center-of-gravity offset of the rubber ring is needed. Utility Model Content

[0003] In view of this, the present invention provides a device for measuring the offset position of the center of mass of a rubber ring. The device is simple to operate, takes little time, saves labor costs as much as possible, and improves the measurement efficiency of the offset position of the center of mass of the rubber ring.

[0004] The technical solution is as follows: A device for measuring the centroidal offset position of a rubber ring includes a base plate, a knife-edge holder, a knife-edge ruler, an optical axis, a rubber ring, an optical axis sleeve, an M6 socket head cap screw, an M4 socket head cap set screw, an M10 socket head cap screw, and an M10 nut (grade C). Two knife-edge holders are connected to the base plate by several M6 socket head cap screws. The two knife-edge holders are symmetrically arranged. A knife-edge ruler is secured to each of the two knife-edge holders by an M4 socket head cap set screw. An optical axis is placed between the two knife-edge rulers. A rubber ring is placed on the optical axis, and an optical axis sleeve is placed on the optical axis. Three M10 socket head cap screws are threadedly connected to the lower part of the base plate, and each of the three M10 socket head cap screws is threadedly connected to an M10 nut (grade C).

[0005] Optionally, a knife-edge ruler holder is used to fix the knife-edge ruler.

[0006] Optionally, the blade ruler can be selected according to the size of the part.

[0007] The beneficial effects are: the device can be selected according to the size of the parts, making the device more versatile; at the same time, the device is simple to operate and takes little time, saving labor costs as much as possible and improving the measurement efficiency of the centroid offset position of the rubber ring.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Example 1: A device for measuring the position of the centroid offset of a rubber ring, such as... Figures 1-3 As shown, it includes a base plate, a knife-edge ruler holder, a knife-edge ruler, a light shaft, a rubber ring, a light shaft sleeve, an M6 socket head cap screw, an M4 socket head cap set screw, an M10 socket head cap screw, and an M10 nut (grade C). Two knife-edge ruler holders are connected to the base plate by several M6 socket head cap screws. The two knife-edge ruler holders are symmetrically arranged. A knife-edge ruler is secured to each of the two knife-edge ruler holders by an M4 socket head cap set screw. A light shaft is placed between the two knife-edge rulers. A rubber ring is placed on the light shaft, and a light shaft sleeve is placed on the light shaft. Three M10 socket head cap screws are threadedly connected to the lower part of the base plate, and each of the three M10 socket head cap screws is threadedly connected to an M10 nut (grade C).

[0014] Optionally, a knife-edge ruler holder is used to fix the knife-edge ruler.

[0015] Optionally, the blade ruler can be selected according to the size of the part.

[0016] When the device is in operation, a rubber ring is placed on the optical axis, and then the optical axis is placed on a knife-edge ruler. A gentle pushing force is applied to the rubber ring. After the optical axis comes to rest, the lower part of the rubber ring is the position of the center of mass deviation, and this position is marked.

[0017] The specific implementation steps are as follows:

[0018] Step 1: Place the device on a flat surface and adjust the three M10 socket head cap screws to make the device level.

[0019] Step 2: Put the rubber ring onto the optical axis.

[0020] Step 3: Place the optical axis with the rubber ring on it onto the device and gently apply a pushing force.

[0021] Step 4: After the rubber ball ring comes to rest, make a mark on the position where the rubber ball is facing down.

[0022] The device can be selected according to the size of the parts, making it more versatile. At the same time, the device is simple to operate and takes little time, saving labor costs as much as possible and improving the measurement efficiency of the centroid offset position of the rubber ring.

[0023] The above description is only a preferred embodiment of the present utility model.
