Abstract
The utility model provides a coupling sleeve step surface to stepped hole surface depth measuring gauge. The measuring gauge comprises a dial indicator, a dial indicator stand fixation block, and a standard block. A step hole is arranged on the bottom end surface of the dial indicator stand fixation block, a fixation hole which runs through the top end surface and the step hole is arranged inside the dial indicator stand fixation block, the measuring rod at the bottom of the dial indicator is inserted into the fixation hole, and the top of the dial indicator measuring rod is extended form the fixation hole and comes into contact with the top of the standard block. When the coupling sleeve step surface to stepped hole surface depth measuring gauge described in the utility model is in use, the end surface of the measuring gauge fits with the end surface of the step, and the measuring gauge only needs to be placed on a standard plane and the zero setting operation is performed on the dial indicator in the process of measurement. Meanwhile, the basic size of the standard block is equal to the size from the step hole to the step surface. The accuracy of the dial indicator is 0.001, that is the measurement error will not be larger than 0.001, so that the requirements of small tolerance and high accuracy are satisfied. The measuring method is simple and rapid, plays a significant role in the control of the percent of pass of products, and ensures the quality of the products from examination.
Description
Technical field
The utility model relates to a kind of cubing, and especially a kind of coupling cover step surface is to shoulder hole face depth check tool.
Background technology
At present, automobile and relevant many mechanical component, especially high-precision part.All with step surface and stepped hole.Step surface is little to the depth dimensions tolerance of stepped hole face, and precision is high.For the size of little and dark hole to step surface, thereby the three-dimensional metering pin can't put in and can't measure.And the method that adopts vernier caliper or pit gauge indirectly to measure, measuring accuracy is inadequate and error is excessive.The quality of quality depends on that usually processing technology guarantees like this, so that the machining precision of product is difficult to control, qualification rate is lower.
Summary of the invention
The purpose of this utility model provides a kind of coupling cover step surface to shoulder hole face depth check tool, and step surface and the stepped hole of measurement part that can be accurate and visual guarantee measuring accuracy, improve the qualification rate of product processing.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the coupling cover step surface is to shoulder hole face depth check tool, it is characterized in that: comprise clock gauge, dial framework fixed block, calibrated bolck, the bottom end face of dial framework fixed block is provided with stepped hole, dial framework fixed block inside is provided with the fixed orifice that runs through top end face and stepped hole, the gauge rod of clock gauge bottom is inserted in the fixed orifice, and the top of clock gauge gauge rod is stretched out in the fixed orifice and contacted with the top of calibrated bolck.
To improvement of the technical scheme: the side of described dial framework fixed block is provided with the fixedly screw of clock gauge gauge rod.
Beneficial effect:
Use coupling cover step surface described in the utility model to shoulder hole face depth check tool, this cubing end face and step end face are fitted, and only need during measurement that cubing is placed on standard flat " 0 " is got final product.Calibrated bolck equals stepped hole to the size basic size of step surface simultaneously.The clock gauge precision is 0.001, and namely measured error can not satisfy the high requirement of the little precision of tolerance greater than 0.001..This measuring method simple and fast has very large effect for the control of product percent of pass, from checking the quality of upper assurance product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model coupling cover step surface as shown in Figure 1 is to shoulder hole face depth check tool, comprise clock gauge 1, dial framework fixed block 2, calibrated bolck 3, the bottom end face of dial framework fixed block 2 is provided with stepped hole, dial framework fixed block 2 inside are provided with the fixed orifice that runs through top end face and stepped hole, the gauge rod of clock gauge 1 bottom is inserted in the fixed orifice, the top of clock gauge 1 gauge rod is stretched out in the fixed orifice and is contacted with the top of calibrated bolck 3, and the side of dial framework fixed block 2 is provided with the fixedly screw 4 of clock gauge gauge rod.
As shown in Figure 1, during measurement, clock gauge is screwed on the dial framework fixed block.Calibrated bolck inserts stepped hole, calibrated bolck length equal the to fathom basic size of size.First measurer is placed on the plane to " 0 " clock gauge during measurement, measurer lower surface and workpiece are fitted fully, and the value with institute's depth measurement degree plus-minus clock gauge during reading gets final product.
