Abstract
The utility model discloses a double-journal detector for step-shaped shafts, which is composed of a base, support nails, a support rod, a dial indicator, a washer and a nut, wherein the base is an angular member, and a bottom side of an internal angle of 90 degrees anticlockwise deflects an angle of 15 degrees to 30 degrees corresponding to the bottom side of the base; the support rod is vertically connected with the upper end of the inner surface of a vertical plate of the base, and a vertical hole is arranged in the middle segment of the support rod for mounting the dial indicator; the center line of the support nails mounted on a bottom plate is on the same plane as the center line of an indicator rod of the dial indicator, and the center line of the support nails mounted on the vertical plate is at the same height as the center of journals to be measured; the height difference of the same row of support nails equals to a half of the nominal size difference of the journals to be measured, and the two support nails on the same shaft segment have the same height. The utility model can simultaneously measure the deviation value of the two journals of a shaft to be measured through positioning and quantitative detection, has easy measurement operation and high efficiency, and is particularly suitable for mass detection on production sites.
Description
Technical field
The utility model relates to a kind of utensil that axle journal detects that is used for, and specifically, the utility model relates to a kind of utensil that is used for detecting simultaneously two sections different nominal size axle journals.
Background technology
The ladder oblique crank Z is the axle of common structure in the plant equipment, and most ladder oblique crank Zs are provided with the important axle journal that matches with bearing more than two sections.After the machine work of ladder oblique crank Z, detecting relevant axle journal shape and scale error has two kinds of methods: the direct method of measurement and relative measurement method.Direct method of measurement outside micrometer areal survey reads detected numerical value one by one, and the measurer that this method is used is conventional measurer, low price, and measuring operation is simple.But this method can only be made Journal Diameter Measuring, can not do shape measure.Relative measurement method uses electronics or air-gauge to measure indirectly, and this method can be carried out axle journal shape and size detection, and measuring accuracy height and Repeatability and Reproducibility error are less.But the amount cubing price that relative measurement method uses is expensive, and sense environmental conditions requires height, the utensil that uncomfortable cooperation production scene quality testing is used.
The utility model content
The utility model proposes a kind of ladder oblique crank Z twin shaft neck cubing that belongs to relative measurement method at the deficiencies in the prior art, and this cubing is simple in structure, cost of manufacture is low, measuring operation is convenient, can measure simultaneously and value is indicated the shape and the dimensional discrepancy of tested axle journal.
The utility model is achieved through the following technical solutions technical goal.
Ladder oblique crank Z twin shaft neck cubing, it is made of pedestal, supporting nail, cradling piece, clock gauge, packing ring and nut.Described pedestal is formed angular member by base plate and riser.Described cradling piece is vertically connected on riser medial surface upper end by packing ring and nut, and the cradling piece stage casing is provided with vertical core clock gauge is installed, the gauge outfit of clock gauge with by the side shaft journal Elastic Contact.The riser of described pedestal and plate inner surface be perpendicular positioning mounting support nail respectively.Its improvements are: the interior angle of described pedestal is 90 ° of right angles, the base of interior angle is with respect to counterclockwise inclined to one side 15 °～30 ° on the base of pedestal, location and installation on base plate supporting nail center line and clock gauge table bar centerline at grade, supporting nail center line and the tested journal centre of location and installation on riser is contour, same row supports half that difference in height between the nail equals tested axle journal nominal size difference, and two supporting staple heights are identical up and down to be in same shaft part.
In the said structure, the supporting on left side nail is higher, the little axle journal of supporting diameter, and the supporting nail on the right is shorter, the big axle journal of supporting diameter.With master bar clock gauge is transferred to zero-bit before detecting, the indicator of clock gauge is measurement error value with respect to the deviate of zero-bit during actual measurement.
The utility model compared with prior art has following benefit:
1, simple in structure, making is easy, cost is low.
2, location, detection by quantitative, measuring operation is easy, the detection efficiency height.
The tested axle journal of the uninterrupted contact of clock gauge gauge outfit when 3, measuring, the shape and size of value indication in real time error.
4, testing environment is had no special requirements, can be used for the production scene and detect.
Description of drawings
Fig. 1 is a diagrammatic cross-section of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Ladder oblique crank Z twin shaft neck cubing shown in the drawings, it is made of pedestal 1, supporting nail 2, cradling piece 3, clock gauge 4, packing ring 5 and nut 6.Described pedestal 1 is the square member in the present embodiment, and the base of its base plate and the lateral surface of riser are perpendicular, and the base of 90 ° of interior angles counterclockwise misplaces 20 ° with respect to the base of base plate, constitutes the variation in thickness of base plate and riser.For example, thin lower end, the upper end of riser is thick.Described cradling piece 3 is by packing ring 5 and riser inside surface vertical be connected of nut 6 with pedestal 1.Cradling piece 3 stage casings are provided with vertical core clock gauge 4, the gauge outfit of clock gauge 4 and tested axle journal 7 Elastic Contact are installed.The table bar centerline that 2 center lines and tested clock gauge 4 are followed closely in the supporting of location and installation on pedestal 1 base plate at grade, 2 center lines are followed closely in the supporting of location and installation on riser and measured axis axle journal 7 centers are contour.In the present embodiment, two bearing journal diameters of measured axis are respectively φ 20mm, φ 25mm.2 high 22.5mm are followed closely in the supporting of the left axle journal of supporting shown in Figure 2, and 2 high 20mm are followed closely in the supporting of support right axle journal.When actual detected, master bar is placed on the supporting nail 2 earlier, gauge outfit and master bar contact position that clock gauge 4 is set are zero-bit, remove master bar, change tested ladder oblique crank Z, the pointer of clock gauge 4 is a deviate with respect to the difference of zero-bit when manually rotating multidiameter.The utility model can accurately be measured two axle journal actual deviation values of measured axis simultaneously by location, detection by quantitative, and whole measuring operation is easy, detection efficiency is high, and measurement environment is not had excessive demand.
