Description
Technical Field
The utility model relates to a ram guide surface and centre bore depth of parallelism detection instrument belongs to the lathe and detects technical field.
Background
The detection of the parallelism between the guide surface of the ram and the central hole is always a technical bottleneck in the related field, if the parallelism between the guide surface of the ram and the central hole can be accurately detected, the precision of a product can be further ensured, and the ram which does not meet the standard is secondarily processed to reach the qualified standard, so that a device is very needed to solve the problems.
SUMMERY OF THE UTILITY MODEL
In order to solve the deficiencies existing in the prior art, the utility model provides a ram guide rail face and centre bore depth of parallelism detection instrument assembles the device to ram centre bore both sides, judges out the depth of parallelism of ram guide rail face and centre bore through the method to major axis dial indicator detection depth of parallelism, simple structure, the precision is high, convenient operation.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a ram guide rail face and centre bore depth of parallelism measuring tool, including axle sleeve A, axle sleeve B and major axis, axle sleeve A and axle sleeve B are the thick top low order trapezoidal axle sleeve of tail end, axle sleeve A's tail end diameter is the same with the left side ram centre bore internal diameter of ram, axle sleeve B's tail end diameter is the same with the right side ram centre bore internal diameter of ram, be equipped with the major axis that can insert in axle sleeve A and axle sleeve B's the shaft hole, its shaft hole diameter is the same with the major axis diameter, axle sleeve A can insert in the left side ram centre bore of ram, and fix with screw through ram side screw in, axle sleeve B can insert in the right side ram centre bore of ram, and fix with screw through ram side screw in.
The ram is placed on a workbench of a planogrinder, the two long shafts are inserted into shaft holes of the shaft sleeve A and the shaft sleeve B, the shaft centers of the left long shaft and the right long shaft are on the same straight line with the shaft centers of the left end and the right end of the center hole of the ram, the parallelism is detected by pulling the surfaces of the two long shafts outside the ram, and the guide surface of the ram is corrected by grinding the guide surface, so that the guide surface of the ram is ensured to be parallel to the center hole.
The utility model has the advantages that: the device is assembled on two sides of the central hole of the ram, and the parallelism between the ram guide rail surface and the central hole is judged by a method for detecting the parallelism by pulling a long shaft meter.
