Embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As depicted in figs. 1 and 2, a kind of for measuring the cubing of tooth pitch, comprise the circumferential detection body 10 that is evenly provided with several teeth groove 11, each teeth groove 11 can with the rim of gear on tooth engagement, detect body 10 and be axially removably connected with turning axle 20, turning axle 20 one end are circumferentially with several perpendicular to the stationary jaw 30 of turning axle 20, and each stationary jaw 30 is threaded with a side of detecting body 10 by bolt 40 respectively.The distance of the both sides of the tooth forming between two adjacent teeth groove 11 in the present invention is set according to desired tooth pitch, does not have the phenomenon of error, thus the accurate tooth pitch of tooth on prototype gear.During tooth pitch on prototype gear, by gear and 10 engagements of detection body, utilize motor to drive turning axle 20 to drive and detect body 10 rotations, if the tooth pitch between each tooth on gear meets processing request, gear can rotate with 10 engagements of detection body, otherwise can not mesh rotation, thereby can detect gear, whether meet processing request.In the time of need to detecting the gear of different tooth pitches, only need to change and detect body 10, because turning axle 20 is to be connected with detection body 10 detachables by stationary jaw 30, only need unclamp bolt 40 shifts out detection body 10 from turning axle 20, on turning axle 20, change again the detection body 10 of corresponding requirements, clamping screw 40, simple to operation, compare manually and measure, measure efficiency and greatly improve.
Preferably, on stationary jaw 30, be provided with the kidney slot 31 along stationary jaw 30 length directions that runs through its two sides, and kidney slot 31 one end are near the junction of stationary jaw 30 and turning axle 20.Kidney slot 31 is set, and the bolt 40 that passes kidney slot 31 can move along the length direction of kidney slot 31, thereby can stationary jaw 30 be locked in a plurality of positions, detects on body 10, flexible.
Further, in one end of turning axle 20, be circumferentially with three stationary jaws 30, and the angle between two adjacent stationary jaws 30 is 120 °, on a side of detecting body 10, be also correspondingly provided with three threaded holes 12, each threaded hole 12 is all on same circumference and this circumference and detection body 10 concentrics, and making the angle between two adjacent screw holes 12 is 120 °.So, three stationary jaws 30 can be corresponding with the position of three threaded holes 12 respectively, and bolt 40 is screwed in threaded hole 12 through kidney slot, stationary jaw 30 can be fixed on and detect on body 10 together with turning axle 20.And utilize three stationary jaws 30 can form more firm support.
For preventing turning axle 20 and detecting eccentric connection of body 10 formations, can on a side of detecting body 10 each stationary jaws 30 of connection, arrange and detect the locating slot 13 for turning axle 20 one end insertions of body 10 concentrics.The center of circle that so can guarantee the axle center of turning axle 20 and detect body 10, on same axial line, can not form eccentric connection and the measurement of impact to tooth pitch on gear.
Preferably, make distance between each threaded hole 12 and locating slot 13 edges all be less than or equal to the length of kidney slot 31, so, when using the detection body 10 of different size, because the diameter of different detection bodies 10 differs, but the diameter of the detent 13 on different detection bodies 10 is consistent with turning axle 20, therefore, the threaded hole 12 of different detection bodies 10 is inconsistent to the distance of locating slot 13, only need guarantee that the distance between each threaded hole 12 and locating slot 13 edges is all less than or equal to the length of kidney slot 31, when connecting, bolt 40 is moved along kidney slot 31, until move to threaded hole 12 places, stationary jaw 30 lockings can detected on body 10.
Because of one end of turning axle 20, insert in locating slot 13, therefore, each stationary jaw 30 is equaled to the degree of depth of locating slot 31 apart from the distance of turning axle 20 ends, so, can make a side of each stationary jaw 30 be close on a side of detecting body 10, convenient fixing.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on instructions, must determine technical scope according to claim scope.
