Description
Technical Field
The invention relates to the field of machine tool checking tools, in particular to a checking tool combination.
Background
The headstock is an important part of the machine tool and is used for arranging the machine tool working spindle and its drive parts and corresponding additional mechanisms. The main spindle box is a complex transmission component and comprises a main spindle assembly, a reversing mechanism, a transmission mechanism, a braking device, an operating mechanism, a lubricating device and the like. The main function of the device is to support the main shaft and make the main shaft rotate, thus realizing the functions of starting, braking, speed changing, reversing and the like of the main shaft.
In the machining of the spindle box, because the space is limited, one surface of the first guide block is used as a fixed-distance surface of the clamp, namely a tool setting zero point surface, and the other surface of the first guide block is used as a guide surface of a workpiece and is combined with the guide surface of the other guide block which is not on the same straight line for use, so that a special measuring tool is required to control the dimensional deviation and the parallelism tolerance of the two guides. Because the front surface and the fixed surface of the clamp are two surfaces with different heights, the distance size and the parallelism tolerance between the two surfaces of the clamp need to be ensured, and the clamp also needs to be controlled by a special measuring tool.
Because the first guide block takes the functions of stroke fixing and guiding into account, after the parallel alignment of two surfaces of 461mm in size and 461mm in size is carried out by utilizing the parallel checking fixture, namely the alignment of the stroke fixing surface is finished, but at the moment, the position of the guide surface of the first guide block on the fixture is not fixed, if the fixture is pinned and fixed, when the guide surface of the fixture is adjusted by the dimension checking fixture, the guide surface of the second guide block is about to follow the linear direction of the guide surface of the first guide block, and the position of the second guide block can deviate from the original design position. Therefore, the situation that the spindle box is placed incorrectly or deviates from the rotation center exists during clamping, and the serious result of the out-of-tolerance of the machined workpiece is caused. Therefore, two sets of independent measuring tools are designed, and the assembling and debugging processes of the clamp need to be completed by combined use.
A measuring and checking tool combination is needed, and the parallelism and the size of two surfaces with different heights, the verticality of two surfaces with different heights and the parallelism and the size of two surfaces with the same heights can be controlled.
