Description

Compression type double-plate guide blind hole checking fixture Technical Field The utility model relates to the technical field of blind hole detection tools, in particular to a compression type double-plate guide blind hole detection tool. Background The blind hole gauge is a tool or device for detecting whether relevant parameters (such as aperture, hole depth, hole position, roundness, cylindricity and the like) of the blind hole meet design requirements. The blind hole inspection tool generally comprises a workbench, a whole positioning mechanism and an inner side wall detection mechanism. The whole positioning mechanism is used for positioning, supporting and clamping a product to be detected, the inner side wall detection mechanism drives the detection part to extend out through the side pushing mechanism, and the hole site of the blind hole on the inner side wall of the product is detected, so that the detection accuracy is improved. When the blind hole is detected, a product is usually positioned on the platform and then a detection needle is inserted into the blind hole for detection, when the existing positioning platform is positioned, the adhesion degree of the product and the platform is not high, the phenomenon of tilting exists, and when the blind hole is detected, the detected hole position depth is inaccurate, and the requirement of detection accuracy cannot be met. Disclosure of utility model The utility model aims to provide a compaction type double-plate guide blind hole checking fixture for overcoming the defects of the prior art. In order to achieve the above purpose, the technical scheme of the utility model is as follows: The utility model provides a clamp-on double-plate direction blind hole examines utensil, including the locating bench that is used for supporting the work piece, the locating bench below is provided with the locating plate, the locating plate is provided with the detection needle, the locating bench shaping has the first locating hole that supplies the detection needle to pass, the locating bench top is provided with the hold-down mechanism who falls the work piece and compress tightly to the locating bench, hold-down mechanism is including can be in locating bench top vertical wobbling clamp plate and with clamp plate complex compression block, the compression block can drive the clamp plate with longitudinal movement and descend. Further, the pressing mechanism further comprises a first support column for installing a pressing plate, one end of the pressing plate is rotatably connected with the first support column, and the pressing plate can longitudinally swing around the top of the first support column.
