Description

TECHNICAL FIELD

[0001] The utility model belongs to sealing ring detection equipment technical field, especially, it is a kind of lip detection device for rotatable shaft seal. BACKGROUND

[0002] The lip of shaft seal is usually formed by cutter cutting, and the surface of the lip after cutting can be seriously affected by tool marks due to tool wear, which affects the sealing effect. The lip surface needs to be detected by a high-power magnifying glass connected with a screen to see if it meets the requirements. Since the magnifying glass is located horizontally above, the lip position is inclined, and the entire circumference of the lip needs to be detected. During detection, the shaft seal needs to be continuously tilted and adjusted by hand to make the lip clearly appear on the screen, which is low in detection efficiency and may not detect the entire circumference. SUMMARY

[0003] The utility model aims at improving the deficiencies of the prior art and providing a lip detection tool for rotatable shaft seal, which tilts the shaft seal itself, and the lip is clearly presented on the screen. The tool is simple and convenient to use without the need to continuously adjust the position and focal length.

[0004] The utility model aims to achieve the following: a lip detection device for rotatable shaft seal, comprising a base, characterized in that the base is provided with an inclined hole, one end of a support rod is installed in the inclined hole with interference, the other end of the support rod is movably installed with a turntable, the top end of the turntable installation end of the support rod is assembled with a clamping spring, the clamping spring is used to prevent the turntable from coming out, the turntable is provided with a step for placing the shaft seal to be detected, the outer diameter of the step is matched with the gap of the shaft seal to be detected, and the outer circle of the turntable has a scale line.

[0005] To further achieve the purpose of the utility model, the angle of the inclined hole can be between 30-50 degrees.

[0006] To further achieve the purpose of the utility model, a bearing can be provided between the support rod and the turntable.

[0007] Compared with the prior art, the utility model has the following remarkable features and positive effects: the turntable is movably installed on the support rod, and the shaft seal to be detected is installed on the turntable. The shaft seal is rotated by the rotatable turntable, which simplifies the operation of workers and facilitates detection. The top end of the support rod is assembled with a clamping spring to prevent the turntable from coming out, which facilitates the disassembly and replacement of other specifications of the turntable. The turntable is provided with a step with an outer diameter matched with the gap of the shaft seal for placing the shaft seal to prevent it from falling. The support rod has a certain inclination angle, which is convenient for detection and solves the detection angle problem of the existing technology, improves the accuracy of detection, and improves the reliability of detection. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 A structural schematic view of the utility model.

[0009] In the drawing: 1, base, 2, support rod, 3, bearing, 4, turntable, 5, shaft seal, 6, step. DETAILED DESCRIPTION

[0010] A rotatable lip detection tool for shaft seal, refer to Figure 1 It is composed of base 1, support rod 2, bearing 3 and turntable 4, base 1 is a disc, and a hole with 30-50 degree inclination angle is arranged at the right position, 40 degree inclination angle is adopted in the embodiment, so that base 1 not only provides an inclined hole but also has the function of stabilizing the gravity center, one end of support rod 2 is assembled in the inclined hole of base 1 through interference, the other end of support rod 2 is assembled with turntable 4 on the stepped shaft, bearing 3 is assembled between the stepped shaft and turntable 4, so that turntable 4 can rotate freely, step 6 is arranged on turntable 4, step 6 is used for assembling the shaft seal 5 to be detected, the outer diameter of step 6 is matched with the shaft seal 5 gap, so as to prevent the shaft seal 5 from falling, and the outer circle of turntable 4 has a scale line.

[0011] When the utility model is used, the whole device is placed below a high-power magnifying glass with an external screen, the shaft seal 5 is sleeved on the step 6 of turntable 4, the scale line of turntable 4 is adjusted to the front after adjusting the focal length, the outer circle of turntable 4 is observed by rotating it gently with hands, and when the scale line of the outer circle of turntable 4 turns back, it is indicated that a circle has been detected.
