Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and more specifically, to an inclined wall thickness measuring device. Background Art

[0002] Before the bearing is officially put into use, accurate thickness detection is a crucial link, which is directly related to the quality control of the bearing and the stability and reliability of the subsequent mechanical equipment operation. However, the bearing thickness detection devices on the market often face some challenges in practical applications, one of which is the stability problem during the detection process. Due to the diversity of the shape, material and surface treatment of the bearing, how to effectively limit the bearing before detection to prevent it from shaking or shifting during the detection process has become the key to improving the detection accuracy. Although most of the existing detection devices are equipped with some form of limit device, these devices are often designed to be simple. The most common method is to fix the bearing with a simple clamp or pressure plate. This method may barely meet the needs in a short period of time, but over time, due to material wear, loose fixtures or design defects, the clamping effect will gradually decrease, causing the bearing to be easily displaced or shaken during the detection process. This will not only directly affect the accuracy of the test results, but may also cause damage to the detection device itself and increase maintenance costs. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an inclined wall thickness measuring device, which has the advantage of high measurement accuracy.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inclined wall thickness measuring device, comprising a workbench, a gear is movably installed at the bottom of the workbench, a motor is fixedly installed at the bottom of the gear, racks are meshed on both sides of the gear, two fixed plates are fixedly installed on the top of the workbench and the two fixed plates are symmetrically placed, round rods are fixedly installed inside the fixed plates and extend to both ends of the fixed plates, a connecting strip is fixedly installed between one end of the round rod and the rack, and a clamping plate is installed at the other end of the round rod.

[0005] As a preferred technical solution of the utility model, an L-shaped plate is fixedly installed on the top of the workbench, a rectangular groove is opened on the inner wall of the L-shaped plate, a threaded rod is movably installed inside the rectangular groove, a connecting shaft is fixedly installed on one end of the threaded rod and the connecting shaft passes through the L-shaped plate, a handle is fixedly installed on the other end of the connecting shaft, a socket block is movably installed on the surface of the threaded rod, and a bearing thickness detector is fixedly installed on the bottom of the socket block.

[0006] As a preferred technical solution of the present utility model, a chute is provided on the inner wall of the rectangular groove, and a slider is movably installed inside the chute and the slider is fixedly connected to the socket block.

[0007] As a preferred technical solution of the present utility model, a motor protection cover is provided at the bottom of the gear and the motor is located inside the motor protection cover, and heat dissipation holes are provided on the surface of the motor protection cover.

[0008] As a preferred technical solution of the present utility model, four sets of legs are fixedly installed at the bottom of the workbench, and leg pads are fixedly installed at the bottoms of the four sets of legs.

[0009] As a preferred technical solution of the present utility model, a rubber layer is provided on the inner wall of the clamping plate, and the workbench is integrally made of stainless steel.

[0010] The measurement process of the bearing bush thickness detector is as follows: First, a laser beam is used to irradiate the surface of the bearing bush, and the thickness of the bearing bush is calculated by measuring the reflection time or angle of the laser beam. Subsequently, the detector processes and analyzes the collected data to obtain the accurate thickness value of the bearing bush. Finally, the detector displays the measurement results in the form of numbers, charts, etc. on the screen for the operator to view.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the power of the motor causes the racks on both sides of the gear to move relatively, so that the two clamping plates move synchronously and limit the bearing shaft on the surface of the workbench. Subsequently, the thickness of the bearing shaft is measured by the bearing bush thickness detector. Compared with the traditional device, this device can ensure that the bearing bush does not move or shake during the measurement process, thereby reducing the measurement error caused by position change, ensuring that the reference point for each measurement is consistent, avoiding the accumulation of errors caused by inaccurate repeated positioning, and at the same time reducing the friction and collision between the measuring device and the bearing bush, thereby prolonging the service life of the measuring device, and reducing the risk of falling off or splashing due to improper operation or external force, which poses a safety hazard to the operator and the measuring equipment.

[0013] 2. By rotating the handle, the socket block on the surface of the threaded rod moves on the surface of the threaded rod, so that the bearing bush thickness detector moves synchronously. Compared with the traditional device, this device can easily adjust the position of the bearing bush thickness detector to adapt to bearing bushes of different sizes, enabling the measuring device to meet diverse measurement requirements, improving the flexibility and applicability of measurement. At the same time, precise positioning of the detector can be achieved, ensuring that the contact surface between the bearing bush thickness detector and the bearing bush always remains parallel or perpendicular, thereby reducing measurement errors caused by position deviation. Moreover, it can ensure that the contact surface between the bearing bush thickness detector and the bearing bush always maintains the correct angle and position, thus avoiding damage to the bearing bush thickness detector or the bearing bush that may occur when they are not parallel or perpendicular.
