Description
Technical field
The utility model relates to a kind of cubing that is used for detection of gear bore position degree.
Background technology
Gear as shown in Figure 1; Have four end-face holes on its end face, four end-face holes are manhole, and end-face hole is mainly bolt via hole, pin-and-hole or fabrication hole; The quantity of end-face hole, diameter, the position is set sets as required; Also be provided with keyway at the center of gear in addition, the gear that the gear that has has keyway, have does not have keyway, is not limited to above-mentioned form.Position degree for this type of gear end face and keyway detects; Usually adopt universal tool-measuring microscope; At first to gather the central point A of two teeth; Press the particular location of rectangular coordinate and each end-face hole of polar coordinate measurement and keyway again through image method and axle cutting method, the universal tool-measuring microscope applied range is fit to the detection of any exposed gear end-face hole and keyway.But because the individual tooth of gear all has corner angle, universal tool-measuring microscope can make image data deviation occur owing to the location is inaccurate when gathering reference point A usually, and especially for spiral gear, deviation can be more obvious; Moreover the detection efficiency of universal tool-measuring microscope is low, and cost is high, and the detection of very improper batch process is difficult to realize industrialization.
The utility model content
The purpose of the utility model provide a kind of simple in structure, detection efficiency is high, cost is low, be fit to the cubing of batch detection gear face hole location.
In order to achieve the above object; A kind of gear end face position cubing that the utility model provides; Comprise body (1), support ring (2), axle (3), register pin (4), location key seat (5), latch (6) and the leg (7) that is used for supporting body (1); Said body (1) is fixedly connected through screw (8) with support ring (2); Said axle (3) is passed the dead in line of the axis and the gear (9) of gear (9), support ring (2) and body (1) and axle (3) from the top down successively; Said location key seat (5) is fixedly mounted on a side of said body (1); Said register pin (4) level is passed the top that location key seat (5) reaches said body (1); The spherical head (4a) of said register pin (4) snaps between two teeth of gear (9) gear (9) location, and said register pin (4) is gone up the end-face hole coupling that is provided with gear (9), has on said body (1) and the support ring (2) and the corresponding latch via hole of said gear (9) end-face hole.
During installation; At first body and support ring are fixed together, afterwards both are sleeved on the axle with screw, again with gear set on axle; The lower surface of gear and support ring are fitted; Gear also can not rotated to prevent gear through the register pin location along the axial-movement of axle by self gravitation simultaneously, and gear is accurately positioned in cubing.Latch inserts on gear end face and body, the support ring and gear end face latch via hole accordingly, if latch can waltz through, then the end face hole location of gear is qualified, otherwise is defective; What end-face holes gear has, and corresponding latch via hole just should be set on body, the support ring, and guarantees that all latches can both be through just meeting the demands.
When having keyway on the said gear (9), this cubing also comprises and the measurement block (10) of the keyway of gear (9) coupling, has the measurement block via hole corresponding with the keyway of gear (9) on the said support ring (2).Measurement block is mainly used in the symmetry that detects keyway, when having keyway on the gear, can in the degree of face position, test side, detect the symmetry of keyway in the lump.
As preferably; Said body (1) is a square; The dead in line of the axis of the center line of said body (1), support ring (2) and said axle (3); Totally three and become circumference uniform distribution along the center line of body (1) on said screw (8), the leg (7) that is positioned at said body (1) below becomes rectangular distribution, makes integral layout more reasonable.
The periphery of latch via hole is provided with fixedly drill bushing (11) in the said body (1), between said axle (3) and the body (1) anti-rotation fixture block (12) is housed, and said anti-rotation fixture block (12) stretches between support ring (2) and the axle (3).Fixedly drill bushing is set on the body, because latch via hole on the body and the complete corresponding setting of the end-face hole of gear make body both can be used as the gear face hole position check tool, can also be as the part of gear face hole drill hole anchor clamps; The anti-rotation fixture block has further prevented to relatively rotate between gear and body, the support ring.
The outer end of said register pin (4) is provided with flexible handle (13); Set pin sleeve (14) is housed on the said location key seat (5), the part that said register pin (4) passes location key seat (5) comprise with the section of being threaded of location key seat (5) and with the wringing fit suit section of said set pin sleeve (14).Flexible handle can be adjusted register pin up and down, and the ball joint head of register pin is fixed on different height, to adapt to the gear location of various outer diameter; Register pin combines the set pin sleeve wringing fit when being threaded with location key seat, cause register pin inaccurate to the gear location to prevent thread looseness.
The beneficial effect of this utility model is: the spherical head through register pin is decided tooth; In conjunction with support ring, the gear in the anchor clamps is accurately located, use the position degree of latch detection of gear end-face hole again; With the symmetry that detects piece detection of gear keyway; Have characteristics such as simple in structure, easy to operate, that detection efficiency is high, cost is low, be fit to batch detection gear face hole location, have vast market prospect.
