technical field

The utility model relates to a bearing raceway angle measuring device, in particular to a medium and large thrust tapered roller bearing raceway and an angle measuring device (measurement ruler) for pressing down the bearing raceway.

Background technique

In recent years, my country's bearing industry is in a period of rapid development, and the production and sales are increasing day by day. Considering the long-term development, users have put forward higher requirements for product quality. This requires our bearings to not only have exquisite appearance quality, but also need to have excellence Intrinsic quality, especially the thrust tapered roller bearing raceway, which is difficult to machine, is even more difficult to measure. Therefore, we conducted research on how to measure quickly and safely.

At present, the raceways of medium and large thrust tapered roller bearings are mostly measured by pushing back and forth on the platform to move the workpiece to be measured. The measurement method is simple, but the error is large and the measurement is slow. It affects the speed and accuracy of processing or inspection, and causes a lot of waste of manpower and material resources.

Utility model content

The technical problem to be solved by the utility model is to provide a medium and large thrust tapered roller bearing raceway angle measuring device that can improve the speed and quality of processing or inspection, save material resources, have good safety performance and high production efficiency.

The technical solutions adopted are:

A medium and large thrust tapered roller bearing raceway angle measuring device, including a square main ruler, a first circular dial indicator, a second circular dial indicator, a dial indicator, a measuring rod, an outer diameter fulcrum and an end thread Fulcrum, characterized by:

A watch rod chute and a fulcrum chute are provided on the square main ruler; a fulcrum positioning chute and a table rod locating chute are provided on the side wall of the square main ruler. The first adjustment ring is set on the table rod of the first circular dial indicator, and the first locking clip is set on the first adjustment ring; the second adjustment ring is set on the table rod of the second circular dial indicator, and the second A second locking clip is set on the adjusting ring. The gauge rods of the first circular dial indicator and the second circular gauge respectively pass through the gauge rod chute, and the distance between the two gauge rods is adjusted according to the measurement requirements of the bearing raceway angle; Insert it into the slot and screw it into the screw hole of the first adjustment ring to position the first circular dial indicator; insert the second flat head screw from the positioning slide slot of the dial rod and screw it into the screw hole of the second adjustment ring. Position the second circular dial indicator.

There is a third locking clip set on the measuring rod, the measuring rod passes through the fulcrum chute, the third flat head screw is inserted from the fulcrum positioning chute, and screwed in the screw hole of the third locking clip, so that the measuring rod Positioning, the gauge stem of the dial gauge is fixed horizontally at the lower end of the gauge gauge stem. The threaded fulcrum on the end face passes through the fulcrum slide groove and is positioned by the thread.

The outer diameter fulcrum is fixed on the lower end of the vertical rod, and the vertical rod is horizontally fixed with a pole, and the left end of the pole is fixedly connected with the connecting plate, and the connecting plate is fixedly connected with the right end of the square main ruler. The lower end of the connecting plate is fixedly connected with a horizontal bar fulcrum.

The above-mentioned measuring device is to measure the axial angle of the raceway by the method of comparative measurement. When measuring, the center line of the tip of the two dial gauges must be on the same straight line as the radial measurement fixed point and the measurement point (following A Bay principle), that is, the outer diameter fixed point and each measuring point are on the same diameter. When measuring, when the auxiliary measuring gauge finds the maximum point, it is the diameter. At this time, the readings of the two axial measuring dial gauges are subtracted. is the angular deviation.

The utility model not only saves the measuring equipment of the large platform, but also greatly improves the safety, is simple to manufacture, facilitates the measurement of the raceways of the medium and large thrust tapered roller bearings of various specifications, and has the advantages of improving the quality of the raceways of the medium and large thrust tapered roller bearings, Improve the work efficiency of workers, reduce the labor intensity of workers and other advantages.
