[0003] Smoothness is one of the important guarantees for the normal operation of bearings. When working, bearings need to form a layer of lubricating oil film on the friction surface to reduce friction and wear and reduce energy loss. If the smoothness of the bearing is insufficient, the friction will increase, which may cause the bearing to overheat, wear more, and even cause failure. Smoothness detection can timely detect the condition of the bearing lubricating oil film and avoid bearing wear and damage caused by poor lubrication. Appropriate smoothness helps reduce the friction loss of the bearing and extend the service life of the bearing.

DETAILED DESCRIPTION

[0029] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] like Figure 1 As shown, a bearing smoothness detection device includes: a frame 100, and a clamping mechanism 200 and a detection mechanism 300 respectively arranged on the frame 100.

[0031] like Figure 2 and Figure 3 As shown, a clamping cavity 110 is provided on the frame 100 , the clamping mechanism 200 is located in the clamping cavity 110 , a rotating plate 120 is provided on the clamping cavity 110 , and the rotating plate 120 is rotatably connected to the frame 100 .

[0032] The clamping mechanism 200 is provided with: a clamping power mechanism 210, a telescopic rod 220 fixedly arranged at the upper end of the clamping power mechanism 210, and a plurality of clamping rods 230 hinged to the telescopic rod 220; the clamping power mechanism 210 is vertically arranged and fixedly connected to the frame 100, and each clamping rod 230 is hingedly connected to a clamping block 240, and a slider is fixedly arranged at the bottom of the clamping block 240, and the slider is slidably connected to the rotating plate 120.

[0033] like Figure 4 As shown, the detection mechanism 300 includes: a detector 310 , a probe moving mechanism 320 fixedly disposed on the detector 310 , and a probe 330 fixedly disposed at the lower end of the probe moving mechanism 320 ; the probe 330 is located above the telescopic rod 220 .

[0034] The cooperation between the clamping rod 230, the clamping block 240 and the detection mechanism 300 can move the bearing in three dimensions after clamping it, and complete the detection of the smoothness of the inner and outer surfaces of the bearing under the action of the probe 330. The bearing can be detected from all directions and has the function of detecting both the inner and outer surfaces of the bearing, which solves the defect in the prior art that it is impossible to detect both the inner and outer surfaces of the bearing.

[0035] The clamping power mechanism 210 includes: a motor 211 and a cylinder 212 fixedly mounted on the motor 211; the cylinder 212 drives the telescopic rod 220 to move vertically, and the motor 211 drives the cylinder 212 to rotate horizontally. The bottom of the motor 211 is fixedly connected to the frame 100, and the cylinder 212 is located directly above the motor 211.

[0036] The cylinder 212 drives the telescopic rod 220 to move vertically, and the telescopic rod 220, the clamping rod 230, the clamping block 240 and the slider constitute a connecting rod mechanism. The vertical movement of the telescopic rod 220 can drive the horizontal movement of the clamping block 240. With the joint work of several clamping blocks 240, the bearing can be clamped.

[0037] The motor 211 drives the cylinder 212 to rotate horizontally. With the support of the rotating plate 120, the telescopic rod 220, the clamping rod 230 and the clamping block 240 rotate together, and the bearing clamped by the clamping block 240 also rotates. The position of the probe 330 is adjusted by the probe moving mechanism 320, so that the smoothness of the inner and outer surfaces of the bearing can be detected during the rotation of the bearing.

[0038] The clamping rods 230 are circumferentially distributed along the axis of the telescopic rod 220, and the hinge points of the clamping rods 230 and the telescopic rod 220 are all located in the same horizontal plane. The clamping blocks 240 all move on the same horizontal plane, and the straight lines of the sliding block movement direction all intersect with the axis of the telescopic rod 220. After the clamping rods 230 are circumferentially distributed along the axis of the telescopic rod 220, the distance of contraction and extension is the same, and the forces exerted on the bearing by the clamping blocks 240 are equal everywhere and the resultant force is balanced, so that the bearing can maintain stability during the clamping process.

[0039] The length of the clamping rod 230 is at least greater than the vertical dimension from the hinge point of the telescopic rod 220 and the plurality of clamping rods 230 to the clamping block 240. The length of the clamping rod 230 must be sufficient to ensure that the motion process of the link mechanism can work smoothly.

[0040] The clamping block 240 is arranged vertically, and the cross section of the clamping block 240 is a fan ring, and the center of the fan ring is located on the axis of the telescopic rod 220. The fan ring shape design of the clamping block 240 can ensure that the contours are close when clamping the inner and outer surfaces of the bearing respectively, increase the contact area, increase the friction between the clamping block 240 and the bearing, and improve the friction between the clamping block 240 and the bearing.

[0041] The clamping block 240 is a concentric fan ring, which contracts inward to clamp the outer surface of the bearing and expands outward to clamp the inner surface of the bearing. It can clamp both the inner and outer surfaces of the bearing, has the adaptability to clamp the bearing, and enhances the applicability of the device to the bearing.

[0042] The probe moving mechanism 320 includes: a probe horizontal moving mechanism 321 and a probe vertical moving mechanism 322 fixedly arranged at one end of the probe horizontal moving mechanism 321; the detector 310 is fixedly connected to the frame 100, the probe horizontal moving mechanism 321 is fixedly connected to the detector 310, the probe horizontal moving mechanism 321 drives the probe 330 to move horizontally, and the probe vertical moving mechanism 322 drives the probe 330 to move vertically.

[0043] The straight line where the probe 330 moves horizontally is perpendicular to the telescopic rod 220. The vertical motion range of the probe 330 passes through at least the horizontal planes where the clamping blocks 240 are located. The telescopic rod 220 is located on the plane where the motion range of the probe 330 is located, so that during the clamping and rotating process of the bearing, the probe 330 can be attached to the bearing surface and detect, ensuring the accuracy of the detection value.

[0044] A bracket 130 is fixedly arranged on the frame 100, and the bracket 130 is used for auxiliary clamping of the bearing. Two rollers are arranged at the end of the bracket 130, and the two rollers are respectively located on both sides of the plane where the motion range of the probe 330 is located, and the rollers can move vertically and horizontally. The midpoint of the line connecting the two rollers is located on the axis of the telescopic rod 220, so that the rollers can maintain the stability of the bearing in the rotation detection to the greatest extent, ensuring the smooth implementation of the detection work.

[0045] When the utility model is used, the bracket 130 , the probe 330 and the clamping block 240 are first adjusted to a suitable position, and the bearing to be tested is placed vertically, and the axis of the bearing coincides with the axis of the telescopic rod 220 .

[0046] When the inner surface of the bearing needs to be inspected, the cylinder 212 is started and the clamping block 240 is contracted and clamped to the outer surface of the bearing through the connecting rod mechanism; the probe moving mechanism 320 is adjusted to make the probe 330 close to the inner surface of the upper end of the bearing, and the bracket 130 is adjusted to make it close to the upper surface of the bearing. The motor 211 is started to rotate the bearing, and the probe moving mechanism 320 is started to make the probe 330 vertically descend for inspection.

[0047] When the outer surface of the bearing needs to be inspected, the cylinder 212 is started and the clamping block 240 is extended and clamped to the inner surface of the bearing through the connecting rod mechanism; the probe moving mechanism 320 is adjusted to make the probe 330 close to the outer surface of the upper end of the bearing, and the bracket 130 is adjusted to make it close to the upper surface of the bearing. The motor 211 is started to rotate the bearing, and the probe moving mechanism 320 is started to make the probe 330 vertically descend for inspection.

[0048] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
