[embodiment]

For the many wedges V tooth on the higher bearing outer wall of accuracy requirement, conventionally adopt the plunge grinding job operation of high-precision diamond truing device trimming wheel, this process can effectively guarantee the constant gap between each V-type tooth, but due to reasons such as lathe rigidity, abrasion of grinding wheel or benchmark conversions, tend to cause with batch many wedges of different product tooth profile of tooth, occur that profile of tooth angle, tooth cross-sectional width, tooth top circular arc R size change in grinding process, even utmost point individual product can exceed tolerance.Overproof product cannot be realized with elevator traction machine profile of tooth steel band and being identical, and not reach desirable transmission contact area, thereby affect smoothness of operation.The present invention utilizes hummer contact susceptibility and instant buzzing warning characteristic, by prior demarcation contact position, according to the sound that whether rings, judges whether profile accuracy meets the demands.

The present invention is as the pick-up unit of tooth error, and it includes pedestal 1, is provided with two parallel round metal bars guide rails 2 on pedestal 1, and the distance between guide rail 2 is the odd-multiple of many wedges tooth 31 space widths; On the pedestal 1 that is positioned at these two guide rails, 2 centres, be provided with metal gauge head 4; Described metal gauge head 4 regulates contact height by the arrangement for adjusting height 5 being located on pedestal 1, and described metal gauge head 4 tops are a convexity arc surface along gyratory directions; At metal gauge head 4 be wherein provided with the power-on detector 6 being formed by power supply 61 and hummer 62 between a guide rail 2, as shown in Figure 4.Before the many wedges tooth bearing 3 detecting as measured workpiece, need first set the original height of measuring contact point 41 on metal gauge head 4.Many wedges tooth profile of tooth angle of causing for lathe rigidity, abrasion of grinding wheel or benchmark conversion is less than normal, tooth cross-sectional width is partially narrow, tooth top circular arc R situation less than normal, can according to tooth Shape Design size calculate on guide rail 2 square guide rail summit 21 at the most wedge tooth tooth top be on metal gauge head 4, to measure the maximum normal distance δ between contact point 41, and measure contact point 41 original positions according to the size adjustment of δ value.While detecting bearing, bearing is placed on two parallel guide rails 2, as less than normal in many wedges tooth profile of tooth angle, when tooth cross-sectional width is partially narrow or tooth top circular arc R is less than normal, two guide rails 2 move with in V-type groove contact point 32 relative design sizes, tooth top sinks, when making a tooth top on outer wall by metal gauge head 4 top along two slow rolling bearings of guide rail, can with measure contact point 41 and contact, the instant buzzing of conducting detector is reported to the police, and shows that product is overproof.Otherwise hummer is not reported to the police, product is qualified.

The present invention utilizes hummer contact susceptibility, by prior setting contact position, and the instant buzzing of conducting detector is reported to the police and is realized flute profile error-detecting, judgement while setting bad profile of tooth tooth top and metal gauge head contact Contact, testing process is directly perceived, accuracy of judgement, detection efficiency are high, can get rid of the uncertain factor of artificial detection judgement completely.This pick-up unit is to realize flute profile error-detecting, judgement by controlling tested tooth top detection contact point displacement situation simultaneously, can concentrated expression profile of tooth angle, the factor such as tooth cross-sectional width, tooth top circular arc R size or set factor cause bad, detecting step is few, economical and easy to operate.

In the present embodiment, be also provided with power switch 63 in described power-on detector 6, during use, power turn-on switch 63 detects.

For different tooth top shape and precision, can adjust by arrangement for adjusting height 5 height of the measurement contact point 41 of metal gauge head 4.Arrangement for adjusting height 5 can be different structure, such as adopting the lifting structure etc. of vertical lifting fine setting.In the present embodiment, arrangement for adjusting height 5 is a pair of adjustment bolt, and described metal gauge head 4 is hinged on pedestal 1 by excentric shaft 7 and can swings around excentric shaft 7, metal gauge head 4 outside surfaces by be screwed on pedestal 1 and parallel with guide rail 2 two adjust bolts and clamp.This is used for promoting metal gauge head 4 around excentric shaft 7 swings to one that adjusts in bolt, and another is used for fixing and clamps metal gauge head.During adjustment, one enters to move back to coordinate to turn this to adjusting bolt, realizes and on metal gauge head 4, measures contact point 41 lift in height fine settings.In the present embodiment, as shown in Figure 4, metal gauge head 4 is arranged on insulating mounting seat 8, and is connected with pedestal 1 by excentric shaft 7.

As shown in Figure 1, in pedestal 1 both sides, be respectively equipped with the parallel baffle 9 that exceeds pedestal 1 end face, the distance between them equals the width of bearing 3, like this, parallel baffle 9 places except playing the positioning action that bearing detects, more steady in the time of can also making bearing roll on pedestal.

In the present embodiment, as shown in Figure 4, distance between pole guide rail 2 is just 3 times of many wedges of bearing V-type space width, the bearing that is odd number for the number of teeth, at this moment the upper end of metal gauge head 4 faces the tooth top of that middle tooth, bearing element center of gravity is consistent with geometric center of gravity, the detection error that can avoid bearing to tilt to cause.
