[0002] Thrust cylindrical roller bearings are widely used in various mechanical equipment, and their performance directly affects the stability and safety of the equipment's operation. To ensure bearing quality, surface runout needs to be measured after manufacturing. Existing surface runout testing methods for thrust cylindrical roller bearings mostly require separate measurements of end face runout and radial runout, necessitating multiple measurements, resulting in long testing times and low efficiency. Therefore, we propose a multifunctional surface runout detector for thrust cylindrical roller bearings. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multifunctional surface runout detector for thrust cylindrical roller bearings. It can realize multi-point end face runout detection and radial runout detection of thrust cylindrical roller bearings at the same time, which greatly shortens the detection time and improves the detection efficiency, and can effectively solve the problems in the background art.

[0009] As a preferred embodiment of this utility model, two mounting brackets are provided, which are symmetrically arranged on both sides of the lifting seat, and the first dial indicators on the two mounting brackets are staggered in the vertical direction.

[0010] As a preferred embodiment of this utility model, a control panel is hinged to the surface of the base away from the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By using several first dial indicators horizontally arranged on the lifting seat to detect the radial runout at various height positions of the thrust cylindrical roller bearing, and by using several second dial indicators vertically arranged on the sliding seat to detect the end face runout at various width positions of the thrust cylindrical roller bearing, it is possible to simultaneously perform multi-point end face runout and radial runout detection on the thrust cylindrical roller bearing, greatly shortening the detection time and improving detection efficiency.

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] Please see Figure 1-4 This utility model provides a technical solution: a multifunctional surface runout detector for thrust cylindrical roller bearings, including a base 1. Guide rods 2 are provided at the four corners of the upper surface of the base 1. A lifting seat 3 is slidably arranged on the outer side of the guide rods 2. The lifting seat 3 is slidably arranged on the guide rods 2, which can detect thrust cylindrical roller bearings of different heights. A horizontal mounting plate 8 is fixedly arranged on the side surface of the lifting seat 3 near the detection end of the first dial indicator 7. A groove 9 is opened in the middle of the upper surface of the mounting plate 8. A sliding seat 10 is slidably arranged in the groove 9. Several second dial indicators 11 are evenly and vertically arranged on the sliding seat 10. The sliding seat 10 can drive the second dial indicators 11 to move along the length direction of the groove 9, which can detect thrust cylindrical roller bearings of different widths. It is applicable to different models of thrust cylindrical roller bearings, improving universality.

[0019] The detection end of the second dial indicator 11 is located below the mounting plate 8. A mounting frame 6 is installed on the side surface of the lifting seat 3. Several first dial indicators 7 are evenly and horizontally arranged on the mounting frame 6 along the height direction. The radial runout of the thrust cylindrical roller bearing at various height positions is detected by the several first dial indicators 7 horizontally arranged on the lifting seat 3, and the end face runout of the thrust cylindrical roller bearing at various width positions is detected by the several second dial indicators 11 vertically arranged on the sliding seat 10. This allows for simultaneous multi-point end face runout and radial runout detection of the thrust cylindrical roller bearing, which is suitable for the inspection of high-precision parts, greatly shortens the inspection time, and improves the inspection efficiency.

[0020] In a preferred embodiment, a fixing plate 4 is fixedly installed at the top of the guide rod 2 to limit the lifting seat 3. A screw 16 is rotatably installed between the base 1 and the fixing plate 4. The screw 16 is threadedly connected to a screw hole on the upper surface of the lifting seat 3, and the top of the screw 16 extends through the upper surface of the fixing plate 4 and is connected to a handwheel 5. Rotating the screw 16 by the handwheel 5 can drive the lifting seat 3 to rise and fall, thus making it suitable for radial runout detection of thrust cylindrical roller bearings at different heights.

[0021] In a preferred embodiment, the sliding seat 10 is slidably disposed on the outer surface of the mounting plate 8, and the upper surface of the sliding seat 10 is provided with anti-slip texture 12, which can increase friction and make it easier to adjust the position of the second dial indicator 11 through the sliding seat 10, thus making it suitable for end face runout detection of thrust cylindrical roller bearings of different widths.

[0022] In a further preferred embodiment, the side surface of the sliding seat 10 is provided with a screw hole, and a fixing bolt 13 is threaded into the screw hole. By tightening the fixing bolt 13, the position of the sliding seat 10 can be fixed, thereby fixing the position of the second dial indicator 11, ensuring the stability of the detection process and the accuracy of the detection results.

[0023] In a preferred embodiment, a control panel 17 is hinged to the surface of the base 1 away from the mounting plate 8. The control panel 17 is electrically connected to an external power supply. A controller is installed inside the control panel 17, preferably a commonly used microcontroller or PLC controller, such as an Arduino series microcontroller or a Siemens S7 series PLC controller. The first dial indicator 7 and the second dial indicator 11 are both commonly used digital dial indicators, such as the Sylvac digital dial indicator 805.7501.10 or the Mitutoyo 543-350-10. Both the first dial indicator 7 and the second dial indicator 11 are electrically connected to the controller. The control panel 17 is also equipped with a touch screen, which is electrically connected to the controller. The touch screen can control the switching of each dial indicator and display its detection value, making it convenient for staff to view.

[0024] The control panel 17 has a hinge setting, which allows the detector to be folded upwards and stored when not in use, reducing space occupation and protecting the touch screen.

[0025] The controller, touch screen, first dial indicator 7 and second dial indicator 11 used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles and circuit connections are all based on metric technology and will not be described in detail here.

[0026] Optionally, two mounting brackets 6 are provided, and the two mounting brackets 6 are symmetrically arranged on both sides of the lifting seat 3. The first micrometers 7 on the two mounting brackets 6 are staggered in the vertical direction. The staggered arrangement of the first micrometers 7 on both sides can expand the range of radial runout detection of the thrust cylindrical roller bearing, which is conducive to simultaneous multi-point detection and higher detection efficiency.

[0027] Optionally, the base 1 has screw holes at the four corners of its lower surface, and an adjusting stud 15 is threaded into the screw holes. A support block 14 is fixedly installed at the bottom of the adjusting stud 15. By rotating the adjusting stud 15 and the support block 14, the levelness of the base 1 can be adjusted, thereby ensuring the accuracy of the thrust cylindrical roller bearing runout detection.
