Summary of the invention
The invention provides a kind of inside race flatness measuring instrument, by rotating tested inside race, by inside race in-plane displancement by lever transmission to surveying instrument, thereby record quickly and accurately the flatness of inside race.
In order to achieve the above object, the invention provides following technical scheme:
A kind of inside race flatness measuring instrument, comprise base, also comprise the location-plate being arranged on base, be arranged on the column on location-plate and be arranged on the measurement bay on column, described location-plate can move around along base, described measurement bay comprises a through hole, in described through hole, measurement instrument is installed; Described measurement bay is also connected with lever bracket, and described measurement bay is flexibly connected with lever bracket, also passes through spring straining between measurement bay and lever bracket; On described lever bracket, be also provided with contact block, described contact block is positioned at the below of through hole, and contacts with measurement instrument gauge head; The end of lever bracket is provided with gauge head; One end away from column on base is fixed with support column, and the supporting of end face cushion is installed on support column, and internal diameter supporting is also installed on column, and described internal diameter supporting is positioned at end face cushion supporting top; Described internal diameter supporting outer rim is fixed with the alloying pellet that spring top is pressed, and described alloying pellet makes the inside diameter surface of measured inside race contact with internal diameter supporting outer fringe surface; Internal diameter supporting top is also provided with gland, for pressing and fixed inner diameter supporting.
As preferably, the quantity of described alloying pellet is three.
As preferably, described measurement instrument is clock gauge.
As preferred version, described measurement bay is connected by rotating shaft with lever bracket.
As preferably, the material of described gauge head is wimet.
As preferred version, the length of described end face cushion supporting is at least 50mm.
Inside race flatness measuring instrument provided by the invention is simple in structure, easy to operate, and for ease of maintenaince, measurement result is accurate, because internal diameter supporting can dismounting and change, therefore can be to different size, and the inside race that inside diameter ranges is 8mm ~ 50mm carries out the measurement of planeness.

Embodiment
Below with reference to specific embodiment, technical scheme provided by the invention is elaborated, should understands following embodiment and only be not used in and limit the scope of the invention for the present invention is described.
Embodiment mono-:
As shown in Figure 1, inside race flatness measuring instrument comprises base 1, is arranged on the location-plate 2 on base, and described location-plate 2 can move around along base 1, and location-plate 2 is fixing by bolt and base 1.Column 3 is installed on location-plate, on column 3, is provided with measurement bay 4.Described measurement bay 4 comprises a through hole 5, in described through hole 5, measurement instrument is installed, and in this example, measurement instrument is clock gauge 6.Lever bracket 7 is also installed on measurement bay 4, and lever bracket 7 is connected by rotating shaft 16 with measurement bay 4, and lever bracket also can use other movable connection methods to be connected with measurement bay, and lever bracket 7 can be rotated up and down along active connection place.Lever bracket 7 is strained by spring 8 and measurement bay 4, is also provided with contact block 9 on lever bracket 7, and described contact block 9 is positioned at the below of through hole 5, and contacts with the gauge head of clock gauge 6.The end of lever bracket 7 is provided with gauge head 10, and gauge head 10 is made up of wimet in this example.On base 1, be fixed with support column 11 away from one end of column 3, end face cushion supporting 12 is installed on support column 11, and for the measured inside race of support, end face cushion supporting 12 can be fixed on support column 11, also can be detachable replacing, to adapt to different inside race sizes.Because inside race flatness measuring instrument provided by the invention is used for measuring the inside race that internal diameter is 8mm ~ 50mm, more than therefore the length of end face cushion supporting 12 generally should be 50mm.Dismountable internal diameter supporting 13 is also installed on column, and described internal diameter supporting 13 is positioned at end face cushion and supports 12 tops.As shown in Figure 2, be socketed in internal diameter supporting 13 for inside race can be stablized, described internal diameter supporting outer rim is fixed with the alloying pellet that spring top is pressed, and described alloying pellet makes the inside diameter surface of measured inside race contact with internal diameter supporting outer fringe surface; The quantity of alloying pellet 14 is preferably three, and when inside race was enclosed within internal diameter supporting when upper, the camber of spring on alloying pellet also produces screen resilience inside race is fixed.Support column is also provided with gland 15 topmost, for pressing and fixed inner diameter supporting.In inside race flatness measuring instrument between each parts connected mode be the conventional methods of attachment such as bolt, screw, rotating shaft.
While measuring inside race, first, according to the internal diameter supporting 13 of the measured suitable size of inside race selection of dimension, internal diameter supporting 13 is arranged on support column 11, loads onto gland 15, make gland compress internal diameter supporting 13.Inside race is socketed in internal diameter supporting 13, and three alloying pellets 14 in internal diameter supporting 13 are adjacent to inside race negative camber, and the elastomeric element connecting on alloying pellet is out of shape and produces screen resilience is fixed in internal diameter supporting 13 inside race.Unclamp the bolt of stationary positioned plate 2, the position of running fix plate 2, and adjust up and down the angle of lever bracket 7, the cemented carbide feeler 10 that makes lever bracket front end contacts with the lower surface of measured inside race, now stationary positioned plate.Before measuring, clock gauge 6 is proofreaded, pointer is made zero.When measurement, pin inside race rotation with hand, lever bracket 7 is along with the rotation of inside race fluctuates, along with floating of lever bracket 7, contact block 9 on lever bracket also can produce upper and lower displacement and conduct to clock gauge gauge head, and displacement maximal value and minimum value can be presented on clock gauge.Therefore, after inside race rotates a circle, can record inside race flatness=displacement maximal value-displacement minimum value.
