Description

Technical Field

[0001] This utility model relates to the field of bearing measurement technology, specifically a flexible measuring machine for railway bearings. Background Technology

[0002] Every parameter of a bearing must be within the acceptable range; otherwise, it will affect the bearing's assembly accuracy during use, thus impacting the operation of the vehicle using the bearing. Therefore, during the bearing production process, it is necessary to measure all dimensions of the bearing to ensure that they are within acceptable limits. For a finished railway bearing, its dimensions must be known. This is done by manually placing the workpiece on a measuring table, manually measuring one dimension, and then placing it on another measuring fixture to measure the remaining dimensions. Currently, measuring the dimensions of finished bearings uses corresponding manual measuring tables. Measuring the same bearing requires switching between several different devices. Given the variety of bearing sizes and types, and the manual operation, the process is complex, cumbersome, inconvenient, and inefficient. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Referring to Figures 1-4, in order to solve the problem that measuring the same bearing requires switching between several different devices, and that bearings vary in size and type, and that manual operation is complex, cumbersome, inconvenient, and inefficient, this invention proposes a flexible measuring machine for railway bearings, comprising a frame 1, a measuring mechanism, a positioning mechanism, and a control computer 4. A platform 2 is fixedly installed on the upper outer surface of the frame 1, and a support seat 3 is fixedly installed on the upper outer surface of the platform 2. The control computer 4 is fixedly installed on the left side of the support seat 3, a first slide rail 5 is fixedly installed on the front outer surface of the support seat 3, a first servo motor 6 is fixedly installed on the upper side of the support seat 3, and a second servo motor 11 is fixedly installed on the lower side of the support seat 3.

[0019] Working principle: When using this railway bearing flexible measuring machine, the workpiece is placed on the rotary table 9 and moved to the position to be measured. After placement, the three servo modules 13 work to center the workpiece at three points. The workpiece can be positioned according to its size. After the workpiece is positioned, the inner diameter measuring mechanism is driven by the first servo motor to lower the inner diameter transfer platform 18 along the first slide rail 5 to the position to be measured. At the same time, the inner diameter measuring head 19 will also be in position. The outer diameter measuring mechanism is driven by the second servo motor 11 to raise the outer diameter transfer platform 20 along the first slide rail 5 to the position to be measured. Then, the transverse motor 14 starts to drive the measuring head transfer platform 16 to move inward along the second slide rail 15 until the outer diameter measurement reaches the predetermined position. Then, the inner diameter measuring head 19 and the outer diameter measuring head 17 move synchronously to the measurement point of the workpiece to be measured. After reaching the measurement position, the third servo motor 12 under the positioning and fixing platform 21 rotates, which drives the connected rotary table 9 to rotate and simultaneously drives the workpiece to rotate for dynamic measurement. After measurement, the data is transmitted to the control computer 4 for recording.

[0020] Compared with related technologies, the flexible measuring machine for railway bearings provided by this utility model has the following advantages: it can measure the corresponding position according to the different sizes of bearings of different models, and can measure bearings of different sizes within the measurement range. The measurement results are displayed in the industrial control computer, which is convenient for judgment and saves time and effort.
