Description
Technical Field
The invention relates to a height adjusting structure of a grinding wheel detecting device, in particular to a static balance detection height adjusting device.
Background
In the machining process of the large gear, a grinding wheel is required to be used for deburring. The grinding wheel is a porous body prepared by adding a bonding agent into an abrasive, compacting, drying and roasting. Because the grinding wheel has different characteristics due to different grinding materials, bonding agents and manufacturing processes, the grinding wheel has important influence on the processing quality, the production rate and the economy of grinding. The grinding wheel is the one with the largest use amount and the widest use range in the grinding tool, rotates at high speed when in use, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, the inner circle, the plane, various molded surfaces and the like of a metal or nonmetal workpiece.
The grinding wheel has the problem of unbalance in actual working operation, and harm caused by the unbalance is mainly reflected in two aspects, on one hand, when the grinding wheel rotates at high speed, vibration is caused, polygonal oscillation marks are easily generated on the surface of a workpiece, and the grinding quality is influenced; on the other hand, unbalance accelerates the vibration of the spindle and the wear of the bearings, which can cause the breakage of the grinding wheel in severe cases, even accidents. The unbalance of the grinding wheel is caused by the fact that the gravity center of the grinding wheel is not coincident with a rotating shaft due to the reasons of inaccurate manufacturing and installation of the grinding wheel, mainly asymmetric geometric dimension of grinding wheel pieces, non-uniform density of each part of the grinding wheel, eccentric installation and the like. The detection process of the grinding wheel is generally to perform static balance firstly, and then to repeat the static balance after the grinding wheel is shaped and trimmed or when unbalance is found in the work.
In the existing static balance detection method, a grinding wheel is fixed on a detection shaft, and then a detection pump is placed on a parallel guide rail. In the detection process, whether the parallel guide rails are horizontal or not is particularly important. Whether the parallel guide rail is horizontal or not needs to be detected by a horizontal detector before detection, and the height of the adjusting bolts for fixing the four corners of the base of the parallel guide rail is adjusted according to a detection result. The operation of the process is complex and can be completed by repeated testing and adjustment.

Scheme II: for the optimization of the basic scheme, the anchoring body is columnar, and fixing rods are arranged on the circumference of the anchoring body. Has the advantages that: the arrangement of the fixed rod can increase the resistance between the floating body and the ice in all directions.
The third scheme is as follows: in order to optimize the basic scheme, the wind shield further comprises a wind shield outer cover leveling mechanism. Has the advantages that: the presence of the wind shield prevents the air flow from affecting the balance of the floating body.
And the scheme is as follows: preferably, the windshield is made of glass. Has the advantages that: the transparent glass material is convenient for operators to monitor the condition of the floating body in the freezing process.
And a fifth scheme: preferably, a limit rope is connected between the wall of the liquid storage tank and the floating body. Has the advantages that: the floating body needs to be in a relatively stable state when being fixed by ice, and the limiting rope stabilizes the effect of the floating body.
