Description
Technical field
The utility model relates to gear testing equipment technical field, especially relates to a kind of gear positioning device.
Background technology
Transmission gear is one of part of speed changer indispensability, to realize gearshift guiding, powerdriven base components, the size of the parts such as gear chamfering and angle can directly affect assembly precision, exercise performance, gear shift flexibility, gear noise and the service life of transmission assembly, therefore, also most important to size and the angle control of the parts such as transmission gear chamfering.
At present the measurement of the parts such as gear chamfering is adopted to contourgraph more, but the measurement stroke of contourgraph is upper and lower linear running, therefore in the time that the parts such as gear chamfering are measured, for the accuracy that ensures to measure, need to meet two benchmark requirements: the one, the axis of gear will with the dead in line of contourgraph, the measuring route that is contourgraph will be by the center of gear, and the 2nd, the end face of gear is parallel with the measuring staff of contourgraph, and the end face of gear will be horizontal.But while using now contourgraph to measure parts such as gear chamferings, the general bench vice that adopts adds gear to fasten, adjust again center and the horizontal level of gear by artificial visual, make the central axes of central axis and the contourgraph of gear, make the end face of gear and the measuring staff of contourgraph parallel, but there is larger error in artificial visual adjustment, cause certainty of measurement poor, and efficiency is low, after clamping, center and the horizontal level of adjusting gear are very inconvenient again for gear simultaneously, in addition, clamp gear by bench vice, also easily cause scratch and the distortion of gear surface.
Chinese patent application publication No.: CN101825519A, Shen Qing Publication day 2010.09.08, a kind of detection clamp of large gear is disclosed, be arranged in the detection platform of gear inspector, comprise and adjust pedestal and the adjustable isometry block of arranging thereon, adjust pedestal and be divided into base and levels adjusting platform, regulate two middle side parts of platform to be provided with in pairs regulating handle at base and lower floor, its top side that is connected to respectively last layer adjusting platform; Regulate the slider bar that arranges by adjacent surface of platform and locating piece to coordinate the location also can relative slippage; The support platform of described adjustable isometry block with block by highly regulating threaded engagement to be connected.Its weak point is, complex structure, comparatively bothers the adjustment of gear, and this detection fixture is only applicable to gear wheel, is not suitable for the gear of various shapes, size, and versatility is poor.
Utility model content
The utility model is when solving existing employing contourgraph the parts such as gear chamfering to be measured, adopt bench vice to position gear, cause certainty of measurement poor, efficiency is low, and easily causes the problem of scratch and the distortion of gear surface, provide a kind of simple in structure, easy to use, fast and accurate for positioning, versatility is good, can improve precision and efficiency of detecting, and be difficult for the gear positioning device of the scratch and the distortion that cause gear surface.
To achieve these goals, the utility model is by the following technical solutions:
A kind of gear positioning device, comprise base, also comprise and draw positive bar, described base is provided with and is the columned apotting spindle of ladder, the path section of described apotting spindle is positioned at apotting spindle top and matches with the endoporus on gear, on described base, be also provided with riser, described riser is positioned at apotting spindle rear and riser is provided with adjustable for height regulating block, the described positive bar that draws passes regulating block and is slidably matched with regulating block, the described positive bar that draws is provided with spacing head near one end of apotting spindle, and described spacing head is suitable with the teeth groove on gear.It is cylindric that apotting spindle is ladder, apotting spindle appear on the stage terrace for holding gears with steady Support Gear, now gear can not rotate, therefore do not need other clamping device location, can avoid scratch and the distortion of gear, but also can directly make gear in level, without adjusting its horizontal level, parallel to ensure the end face of gear and the measuring staff of contourgraph, the path Duan Ze of apotting spindle is just through the endoporus on gear, make gear at X, in two rectilinear directions of Y, can arbitrarily not move, but can rotate, be convenient to the adjusting of circumferential position, when use, as long as by the dead in line of the central axis of apotting spindle and contourgraph, after gear is placed on apotting spindle, the central axis of gear just with the dead in line of contourgraph, without the center of adjusting gear, adopt apotting spindle to position gear, convenient, accurately, can greatly improve precision and efficiency of detecting, spacing head plays spacing effect, and spacing head is inserted after the teeth groove on gear, and because spacing head is stuck in teeth groove, gear upwards can not rotate in week, sliding shoe height is adjustable, makes the utility model can be used for the part of different-thickness, and versatility is good.
As preferably, on described base, be fixed with adjusting screw(rod), the bigger diameter end of described apotting spindle is threaded with adjusting screw(rod).The bigger diameter end of apotting spindle is threaded with adjusting screw(rod), is convenient to change different apotting spindles to adapt to different gears, thereby improves versatility of the present utility model.
As preferably, described base both sides are provided with for base being fixed on to the open slot on contourgraph pedestal by bolt.When the central axis of axle to be positioned and the dead in line of contourgraph, by the cooperation of bolt and open slot, base can be fixed on contourgraph pedestal, so just, make the center of apotting spindle can not be offset, improve stability, open slot is the link position of capable of regulating bolt also, to improve versatility of the present utility model.
As preferably, described spacing head is made as the cylinder of sphere for end.Spacing head, for end is made as the cylinder of sphere, is difficult for the surface of scuffing gear.
As preferably, described riser is provided with chute, and described regulating block is provided with double-screw bolt near a side of riser, and described double-screw bolt is through chute, and described regulating block is fixedly connected with coordinating with riser of nut by double-screw bolt.Chute plays the effect of leading with spacing, and nut coordinates with double-screw bolt, simple in structure, easy to adjust.
Therefore, the utlity model has following beneficial effect:
(1) fast and accurate for positioning, can improve precision and efficiency of detecting, be difficult for causing scratch and the distortion of gear surface;
(2) stability and versatility are good;
(3) simple in structure, easy to use.
