The online measuring device is divided into two types of double-point measurement and single-point measurement, wherein the accuracy of the double-point measurement is higher, the program is simpler, and therefore the online measuring device is widely applied. The existing online measuring device is usually arranged on the opposite side of the grinding wheel, and the measuring operation is required to be carried out after the device moves forwards during measurement, so that the processing time of a single piece is prolonged, and the production efficiency is reduced.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides an outer circle fine grinding device which is mainly technically characterized in that an online double-point measuring device is arranged on a grinding wheel frame, so that a grinding wheel and the measuring device synchronously move, the execution path of the online measuring device is reduced, and the production time of a single piece is shortened. The technical scheme for achieving the purpose is as follows:
an outer circle fine grinding device comprising: the device comprises a frame, two grinding wheel mechanisms and a measuring tape, wherein the two grinding wheel mechanisms are arranged up and down and are positioned on the frame.
The side of the frame is provided with a guide rail, and the rear side of the grinding wheel mechanism is provided with a lifter which slides in the guide rail, so that the grinding wheel and the measuring tape are brought to the position of the workpiece to be ground. The central lines of the upper grinding wheel mechanism and the lower grinding wheel mechanism are aligned, the grinding wheel mechanism comprises a grinding wheel frame and a grinding wheel, the grinding wheel frame is semi-surrounded on the outer side of the grinding wheel, and a motor is arranged in the grinding wheel frame to drive the grinding wheel to rotate. The measuring rule comprises an upper rule plate and a lower rule plate, and the sections of the upper toothed plate and the lower toothed plate are right-angled triangles. The section of the workpiece to be measured can be tightly propped by the upper ruler plate and the lower ruler plate to be measured at two points. The upper ruler plate is arranged on the front end face of the upper grinding carriage, and the lower ruler plate is arranged on the front end face of the lower grinding carriage; and the rear sides of the upper toothed plate and the lower toothed plate are respectively provided with a slider. The upper ruler plate and the lower ruler plate can slide on the gear rack to adapt to workpieces to be ground with different diameters.
The maximum distance between the edges of the upper grinding wheel and the lower grinding wheel, which are close to each other, is smaller than the diameter of the workpiece to be ground, the connecting line length of the contact points of the upper grinding wheel and the workpiece to be ground is the chord length of the section of the workpiece to be ground, and the chord length is smaller than the diameter of the section of the workpiece to be ground, so that the diameter of the section of the workpiece to be ground is yielded, the upper toothed plate and the lower toothed plate are contacted with the same, and the measuring rule accurately measures the diameter of the workpiece to be ground. The toothed plate material hardness is greater than the material hardness of the workpiece to be ground, so that the measurement accuracy and the service life of the toothed plate are ensured.
The beneficial effects of the invention are as follows:
1. the measuring ruler and the grinding wheel mechanism are arranged into a whole, so that the mechanical volume is reduced, and the operation space is enlarged;
2. the measuring rule and the grinding wheel mechanism move together, so that the measuring precision is increased, the execution route of the measuring rule is shortened, the single-piece production time is shortened, and the production efficiency is improved;
3. the measuring ruler can accurately measure the diameter of a workpiece to be ground, and the machining precision of the grinding machine is improved.
