Description
Technical field
The present invention relates to punching press detection field, particularly spoke loses the locating check fixture of circularity.
Background technology
Spoke is the protection wheel rim of wheel of vehicle, the device of spoke; its structure is generally a pair circular cover plate; the diameter of cover plate and the diameter of wheel rim are close; there are the hole being greater than axis of wheel rotation in the central authorities of cover plate; connect antermarginal part at cover plate and have aperture; there is annular wheel plate at the edge of cover plate, and the curved surface of wheel plate can fit tightly with the curved surface of wheel rim.Along with the fast development of automobile industry, increasing people adopt automobile as walking-replacing tool, and the product quality of spoke also receives much concern.Wherein, the mistake circularity of spoke is more crucial detected parameters, after spoke stamping completes, above the wheel hub that can be arranged on automobile, and if spoke to lose convexity ratio comparatively large, automobile there will be strong vibrations, reduces security and the comfort level of Integral automobile.
For this reason, prior art after spoke stamping, can carry out the detection of losing circularity to spoke.First spoke can be placed in the horizontal plane, make it rotate, then dial gauge is fixed on holding frame, aim at the arc edge of spoke with the gauge head of dial gauge, the situation of its circular runout is detected.Wherein dial gauge is the general dimensional measuring instrument of tabular form utilizing accurate rack and pinion mechanism to make, and is usually made up of gauge head, gauge rod, antirattle spring, tooth bar, gear, hairspring, round dial and pointer etc.The operation principle of dial gauge is the small rectilinear movement of measuring staff caused by measured size, amplifies through gear drive, becomes and refers to the rotation of meter on dial, thus read the size of measured size.If the measurement numerical value of dial gauge is greater than 0.4mm, illustrate that circular runout is larger, it is comparatively large that this spoke loses convexity ratio, and spoke is off quality; If the measurement numerical value of dial gauge is less than or equal to 0.4mm, circular runout is smaller, then spoke is up-to-standard.But the bottom of spoke, in rotation process, is not easy to fix a central point and rotates, for bringing difficulty with centimeter check.
Summary of the invention
The object of this invention is to provide the locating check fixture that spoke loses circularity, can carry out axially and radial location spoke, improve the accuracy that spoke loses roundness measurement.
The invention provides a kind of base case: spoke loses the locating check fixture of circularity, comprise pedestal, mount pad and the mandrel for the tight spoke mesopore of locating clip, mount pad is positioned at impact faces and is fixedly connected with pedestal, and mount pad is cylinder, and mandrel is positioned at the geometric center of mount pad; The top of mount pad is provided with the installed surface matched with spoke arc surface.
Operation principle and beneficial effect are: first the mesopore of spoke aims at mandrel, and spoke tips upside down on above the installed surface of mount pad, and the mesopore of spoke is through mandrel, and other parts of spoke and installed surface fit, and are positioned by the mesopore of spoke.Then near spoke, be fixed on the dial gauge on holding frame, the gauge head of dial gauge aims at the external arc edge of spoke, stir spoke and make it rotate around mandrel on installed surface, the gauge head of dial gauge there will be the measurement numerical value of beating, divided by the mistake circularity of observation value to spoke, thus judge that whether spoke is qualified.
The present invention, by arranging pedestal, for ensureing that locating check fixture is in horizontal reference, thus prevents test surfaces from tilting to cause testing result to have deviation.Arrange mount pad, installed surface matches with spoke arc surface, conveniently spoke is carried out installation location, thus ensures to be positioned at same horizontal plane in test rotary course, positions upward spoke shaft.Be provided with mandrel above mount pad, mainly radial location carried out to spoke, spoke is rotated around mandrel, be convenient to dial gauge detect its external arc, thus detect the mistake circularity of spoke, get rid of substandard product, thus ensure that spoke is arranged on above automobile, there will not be jumping phenomena.
Further prioritization scheme one for base case: mandrel is cylindrical projection.The setting of mandrel, mainly in order to the mesopore of fixing spoke, positions spoke.So mandrel can be set to cylindrical projection, the mesopore of spoke is through projection, and structure is simple.
Further prioritization scheme two for base case: mandrel is the annulus of hollow, and the axial direction of mandrel offers expanding trough, is provided with the nose bar for distending mandrel in mandrel.Because the mesopore of spoke rotates through mandrel, in order to make it locate clamping better effects if, can axially offer multiple expanding trough at mandrel, by nose bar, mandrel externally being extruded, mandrel carries out crimp to multiple faces of spoke, thus makes spoke locating effect better.
Further prioritization scheme three for prioritization scheme two: the lower end of nose bar is round platform, and nose bar end is provided with down-pressed pole, and down-pressed pole is provided with movable block, is provided with the groove coordinated with nose bar above movable block, down-pressed pole through movable block and nose bar hinged.In order to by outside for mandrel crimp, nose bar lower surface is set to round platform, meanwhile, the down-pressed pole hinged with nose bar is set on nose bar, can by pressure depression bar, thus nose bar be moved upward.Lower surface due to projection is round platform, and mandrel can outwards extrude by the both sides of projection, thus the mandrel expanded in being formed, the mesopore of spoke is better located and is clamped in above mandrel, thus ensure the accuracy rate of detection.
Further prioritization scheme four for base case: installed surface comprises the stationary plane of intermediate projections and the horizontal plane corresponding with spoke border.Because spoke itself is not regular shape, the Inner arc of spoke raises up, and external arc concaves, so the circular arc arranging installed surface and spoke fits, thus making spoke in rotary course, the arc surface of spoke fits with installed surface always, ensures the location clamping axially.
Further prioritization scheme five for base case or prioritization scheme two: be arranged with baffle ring outside mandrel.Axially expanding trough is offered due to mandrel; after the mistake roundness measurement of spoke; baffle ring is enclosed within outside mandrel; can prevent down-pressed pole from driving nose bar to move upward because of gravity; thus by mandrel to external pressure; cause mandrel to be in outwardly state for a long time, thus produce distortion, arranging baffle ring can play a protective role.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of embodiments of the invention 1;
Fig. 2 is the structural representation of embodiments of the invention 2
