Technical field

The utility model relates to a kind of raceway angle measurement unit, specifically a kind of medium-and-large-sized bearing rollaway nest of thrust cone roller and depress the angle measurement unit (survey chi) of raceway.

Background technology

In recent years, China's bearing industry is in the high-speed developing period, volume of production and marketing improves day by day, consider that from long term growth the user has higher requirement to product quality, this just requires our bearing not only exquisite presentation quality will be arranged, and also needs to have excelsior inherent quality, especially bearing rollaway nest of thrust cone roller, and raceway is difficult to processing, measure just more difficult.Therefore we for how, measurement fast and safely is studied.

Current medium-and-large-sized bearing rollaway nest of thrust cone roller is measured adopt more and is pushed back movingly on platform, and mobile measured workpiece is measured, and measuring method is easy, but error large, measure slow.Impact processing or the speed, the precision that check, caused very large human and material resources waste.

The utility model content

The technical problems to be solved in the utility model, be to provide a kind of speed, quality that can improve processing or check, saves material resources, security performance is good, the medium-and-large-sized bearing rollaway nest of thrust cone roller angle measurement unit that production efficiency is high.

The technical scheme adopted is:

A kind of medium-and-large-sized bearing rollaway nest of thrust cone roller angle measurement unit, comprise square main scale, the first circular clock gauge, the second circular clock gauge, dial gauge, meter bar, external diameter fulcrum and end-face helical fulcrum, it is characterized in that:

Offer table bar chute and fulcrum chute on square main scale; Offer fulcrum positioning runner and table bar positioning runner on square main scale sidewall.On the table bar of the first circular clock gauge, suit the first adjustment ring, be set with the first locking clamp on the first adjustment ring; Be set with the second adjustment ring on the table bar of the second circular clock gauge, be set with the second locking clamp on the second adjustment ring.The table bar of the first circular clock gauge and the second circular clock gauge passes respectively table bar chute, and sets up two table bar distances by raceway measurement of angle requirement; The first flat head screw is inserted from table bar positioning runner, and revolves in the screw of being located at the first adjustment ring and make the first circular clock gauge location; The second flat head screw is inserted from table bar positioning runner, and revolves in the screw of being located at the second adjustment ring, makes the second circular clock gauge location.

Be set with the 3rd locking clamp on the meter bar, the meter bar is through the fulcrum chute, and the 3rd flat head screw is inserted from the fulcrum positioning runner, and revolves in the screw of being located at the 3rd locking clamp, makes meter bar location, and the table bar of dial gauge laterally is fixed on the lower end of meter bar.The end-face helical fulcrum, through the fulcrum chute, is located by screw thread.

The external diameter fulcrum is fixed on the lower end of vertical rod, laterally is fixed with pole in vertical rod, and the left end of pole is fixedly connected with web joint, and web joint is fixedly connected with the right-hand member of square main scale.The lower end of web joint is fixedly connected with the horizontal stripe fulcrum.

Above-mentioned measurement mechanism is that the method by comparing and measuring axially takes measurement of an angle to raceway, the center line of table point that must two clock gauges during measurement and radial measurement point of fixity and measurement point (are followed abbe ' s principle) on the same straight line, namely external diameter point of fixity and each measurement point are all on same diameter, during measurement, the subsidiary table is exactly diameter while finding maximum point, now reading two readings of axially measuring clock gauge and subtract each other, is angular deviation.

The utility model has not only been saved the measuring equipment of large platform, also greatly improved security simultaneously, manufacture simple, being convenient to the medium-and-large-sized bearing rollaway nest of thrust cone roller of all size measures, there is the medium-and-large-sized bearing rollaway nest of thrust cone roller quality of improvement, improve workman's work efficiency, reduce the advantages such as labor strength.
