Description
Technical field
The utility model belongs to machine components detection device field, especially has with a kind of valve seat depth of chamfering measurement apparatus
Close.
Background technology
Valve seat is a kind of conventional refrigeration air-conditioner accessory, is made up of inside it the hole of multiple insertions, in the endoporus of valve seat, is
Reducing stress concentration needs to carry out the sharp edge of endoporus chamfer machining, the depth of interior chamfering whether exact relationship to valve seat matter
Whether amount is qualified.
At present, for the depth survey of chamfering in valve seat, one kind is to coordinate depth gauge rule to carry out greatly using making standard feeler gauge
Bulk measurement, measurement accuracy is not high, can not meet the requirement of high-precision product.Another way is to split valve seat from center, is made
Measured with projecting apparatus, although this metering system precision is higher, so valve seat can be caused to damage, and can not measured one by one,
Measurement efficiency is relatively low, it is impossible to ensures strict demand of the valve seat to quality.
Utility model content
The purpose of this utility model is intended to overcome problem present in above-mentioned background technology, there is provided a kind of easy to operate, inspection
Survey the valve seat depth of chamfering measurement apparatus of precision and efficiency high.
Therefore, the utility model uses following technical scheme：A kind of valve seat depth of chamfering measurement apparatus, it is characterized in that, institute
Stating measurement apparatus includes measuring table, measurement pedestal, amesdial check and correction reference block, measurement head and amesdial, and measurement pedestal is by upper
Cylinder and lower cylinder composition, the lower cylinder bottom surface for measuring pedestal are posted by measuring table and can be on the measuring table
Move freely, the upper cylinder top end for measuring pedestal is provided with circular arc dovetail through-hole groove, and amesdial check and correction reference block is plugged in
In the circular arc dovetail through-hole groove of cylinder top end, measurement head is Step Shaft, and measurement head center is provided with cylindrical hole, measurement head
Big end periphery is provided with a tapped through hole, and amesdial is plugged in the cylindrical hole of measurement head and by the big end spiral shell of measurement head
Screw in line through hole is fixed.
As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
The amesdial check and correction reference block is crescent, and the center of amesdial check and correction reference block is provided with rectangular recess, rectangle
Reference plane of the groove bottom land as measurement.
The utility model can reach following beneficial effect：1st, by the way that the measurement head for being provided with amesdial is placed on into thousand
Point table check and correction reference block measures the correction of size, valve seat is installed on measurement pedestal during measurement, insertion amesdial check and correction
Reference block, is then put into measurement head in the valve seat endoporus to be measured, you can falling for valve seat endoporus is quickly measured by amesdial
Pull degree, both current metering systems are compared, the present apparatus can not only improve measurement accuracy, and can improve measurement efficiency,
Valve seat will not be caused to damage simultaneously；2nd, the present apparatus is simple in construction, installation cost is low and easy to use, can at the scene quick and precisely
Detect the quality of product.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes measuring table 1, measurement pedestal 2, amesdial check and correction reference block 3, measurement head 4
With amesdial 5, measurement pedestal 2 is made up of upper cylinder and lower cylinder, and the lower cylinder bottom surface of measurement pedestal 2 is posted by measurement
Platform 1 can simultaneously move freely on measuring table 1, and the lower cylinder bottom surface of measurement pedestal 2 is provided with cylinder shape groove, can make measurement
Pedestal 2 can be smoothly posted by measuring table 1, and the upper cylinder top end of measurement pedestal 2 is provided with circular arc dovetail through-hole groove, and thousand
It is crescent to divide table check and correction reference block 3, and amesdial check and correction reference block 3 is plugged in the circular arc dovetail through-hole groove of cylinder top end
Interior, the center of amesdial check and correction reference block 3 is provided with rectangular recess, reference plane of the rectangular recess bottom land as measurement, and measurement head 4 is
Step Shaft, the center of measurement head 4 are provided with cylindrical hole, and the big end periphery of measurement head 4 is provided with a tapped through hole, amesdial
5 screws for being plugged in the cylindrical hole of measurement head 4 and in the big end tapped through hole for passing through measurement head 4 are fixed.
The utility model to amesdial 5 in use, first correct, and during check and correction, the plane of measurement head 4 must be with amesdial school
The reference plane of reference block 3 is bonded；After the completion of check and correction, the pointer of amesdial 5 goes to zero-bit.
