On the premise that whether the depth of the inclined water hole reaches the production requirement standard or not can be detected, the error value of the inclined water hole and the standard length can be detected, the tail end of the measuring core at the same end of the reference step surface extends downwards by taking the tail end of the measuring core as a zero scale value, when the measuring core is higher than the reference step surface, the depth of the inclined water hole is smaller than the standard depth, and the error value can be reflected by the scale value on the tail end of the measuring core.
Optionally, a scale value is arranged on the inner wall of the core measuring matching hole at one end of the reference step surface, the scale value extends downwards with the tail end of the core measuring clamping groove as a zero point, and the scale value is larger than the maximum value of a negative error and is used for measuring the specific value of the inclined water hole depth larger than the standard depth.
In this embodiment, the end of the measuring core at one end of the reference step surface is used as a zero point to extend downwards to form a scale value, when the measuring core is lower than the reference step surface, the depth of the inclined water hole is larger than the standard depth, and an error value can be reflected by the scale value on the inner wall of the measuring core matching hole.
Optionally, the core is detachably arranged in the core matching hole.
After using this utensil is examined to frock to measure oblique water hole for a long time, survey the core and may receive wearing and tearing, can make the testing result error like this, consequently when other parts that wear and tear or this utensil is examined to survey the core appear go wrong, need not examine utensil whole frock and all do nothing in order to cause the waste of resource, survey the core in this embodiment and survey the core mating holes and be connected for dismantling, so not only can save the resource, can also improve the detection range of this utensil is examined to the frock.
Optionally, an angle formed by the reference inclined plane and the core measuring matching hole is matched with an angle of the inclined water hole of the cylinder cover to be detected.
Because the oblique water hole of cylinder head is not the vertically with the top surface of this cylinder head, so in order to can be more convenient to put into this oblique water hole with surveying the core, the oblique angle that the benchmark inclined plane and survey core mating holes are constituteed should be unanimous with the oblique angle that cylinder head top surface and oblique water hole are constituteed, like this when the benchmark inclined plane and this cylinder head laminating, survey the core and just can put into oblique water hole.
Optionally, the tool checking fixture is further provided with a carrying handle;
optionally, the carrying handle is provided with anti-slip plastic.
In order to be convenient for the detection personnel to use or carry the tool, the side face of the tool detection device is provided with the carrying handle, and the handle is provided with anti-skidding plastic, so that the situation that the tool detection device drops due to the fact that the handle is too smooth to hold by the detection personnel can be reduced.
Optionally, the length of the part of the countersunk head fastening screw for rotational fastening is greater than the length of the side threaded hole and less than the sum of the length of the side threaded hole and the width of the core measuring clamping groove.
In this embodiment, in order to facilitate the detachment of the measuring core, the head of the countersunk head fastening screw is provided with a fastening groove or a fastening bolt, and the fastening groove may be in a straight shape, a cross shape, or a hexagon socket shape, which is not limited herein.
