Abstract
The utility model relates to the field of mechanical machining and provides a crankshaft eccentric-circle and stern-notch angle measuring instrument which is used for detecting whether machining of a crankshaft of an air condition compressor is qualified. The instrument includes a V-shaped support. One end of the V-shaped support is provided horizontally with a positioning pin and the other end of the V-shaped support is horizontally provided with two dial indicators symmetrically. The crankshaft eccentric-circle and stern-notch angle measuring instrument is simple in structure, convenient to use and capable of detecting whether the central axis of a stern notch coincides with the symmetrical axis of an eccentric circle on the crankshaft.
Description
Technical field
Whether the utility model relates to field of machining, is specifically related to a kind of crankshaft eccentric circle and stern notch angle measuring instrument, qualified for detection of air-conditioner compressor crankshaft processing.
Background technology
Compressor of air conditioner is in air-conditioning refrigerant loop, to play compressible drive cold-producing medium, is the important component part of air-conditioning equipment.And wherein bent axle is the core of compressor, belong to precision component, so the quality of bent axle directly has influence on serviceable life and the effect of air-conditioning.At present, in air-conditioning production run, to the processing of the parts such as bent axle, in semi-automatic standard, its speed of production has had raising at full speed, but its supporting finished product detection equipment do not have, and has therefore greatly affected the production efficiency of bent axle.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art part, a kind of crankshaft eccentric circle and stern notch angle measuring instrument are provided, it is simple in structure, easy to use, can effectively detect the central shaft of the stern notch on bent axle and whether the axis of symmetry of off-centre operation overlaps.
The purpose of this utility model is achieved by the following technical measures: a kind of crankshaft eccentric circle and stern notch angle measuring instrument, comprise V-type support, and one end of V-type support has been horizontally disposed with register pin, and the other end symmetry of V-type support has been horizontally disposed with two dial gauges.
In technique scheme, described V-type support is fixed on horizontal base plate.
In technique scheme, described register pin frame is fixed on horizontal base plate by support, and dial gauge is fixed on horizontal base plate by support.
The utility model is simple in structure, easy to use, and the dial gauge of justifying both sides by crankshaft eccentric can detect fast and accurately the central shaft of the stern notch on bent axle and whether the axis of symmetry of off-centre operation overlaps, and improves the production efficiency of bent axle.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model crankshaft eccentric oil groove detector.
Fig. 2 is the work schematic diagram of the utility model crankshaft eccentric oil groove detector.
Wherein: 1. V-type support, 2. register pin, 3. left dial gauge, 4. right dial gauge, 5. bent axle.
Embodiment
The bent axle being applied on compressor of air conditioner is processed with stern notch at its tail end face, in its stem, be processed with off-centre operation, the device that the utility model provides is exactly for detecting the central shaft of this stern notch and whether the axis of symmetry of off-centre operation overlaps, if overlapped, is certified products.
Below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, the present embodiment provides a kind of crankshaft eccentric circle and stern notch angle measuring instrument, comprises V-type support 1, and one end of V-type support 1 has been horizontally disposed with register pin 2, and the other end symmetry of V-type support 1 has been horizontally disposed with two dial gauges in left and right.
In the above-described embodiments, described V-type support 1 is fixed on horizontal base plate.Described register pin 2 is fixed on horizontal base plate by support, and dial gauge is fixed on horizontal base plate by support.
As shown in Figure 2, when the present embodiment is used, the bent axle processing 5 afterbodys are positioned on V-type support 1 towards register pin 2, register pin 2 are inserted in the stern notch of bent axle 5.Now, the gauge head of left and right dial gauge should be against on the off-centre operation of bent axle 5, and the off-centre operation of bent axle 5 should be in symmetrical state by design.Read the data of left and right dial gauge, if the numerical value that left dial gauge 3 and right dial gauge 4 differ is in margin tolerance, illustrate that this off-centre operation is symmetrical, it is qualified that this finished product is produced.
