Valve guide bushing is sent to the rear portion of positive connecting gear by semicircular transport track, realizes the commutation of valve guide bushing, or changes
Rotate 180 degree in the horizontal plane to connecting gear itself, after realizing the commutation of valve guide bushing, be more forward sent to main transmission
Mechanism.
In prior art, in order to realize the walking direction to valve guide bushing, need to be in production and processing valve guide bushing, in valve
The a certain position of catheter outer surface processes groove, and then by the radial direction probe basis in transmission equipment, the detection of groove is sentenced
Other valve guide bushing direction of transfer just or instead.Although the work that this technological design completes transmission and differentiates direction, lead simultaneously
The valve guide bushing has been caused to remove outside the required functional structure of electromotor work, multi-processing outer surface groove, and it is just this groove shadow
Ring slickness and the integrity of valve guide bushing outer surface, caused valve oil seal and the axiality of conduit to reduce, make valve oil seal
Not just rate of installing increases, and also reduces the width of valve oil seal band simultaneously, affects sealing property.And then affect electromotor
Combination property.Thus, compared to technological design of the prior art, the valve guide bushing transmission equipment that the present invention provides is not affecting
Transmission work and differentiate direction accuracy while, it is to avoid the presence of the redundancy structure of valve guide bushing, thus eliminate setting
The standby interference to electromotor overall performance.
Transmit in the preferred implementation of method for sorting a kind of with regard to valve guide bushing, the valve guide bushing that transmission is come is carried out
Position and compress to determine its test position.Meanwhile, in the end Internal periphery of compacted valve guide bushing and detection means
Probe offset, when the place that offsets end Internal periphery be on-right angle when, probe with this end Internal periphery there are not location conflicts, then
Probe is not in turn resulted in the triggering of signal by promotion, and it is forward direction that this state is judged as valve guide bushing, now by valve guide bushing to
First avris upset, makes valve guide bushing tumble to positive connecting gear, and then forwards；When the end Internal periphery at the place of offseting is
During right angle, there are location conflicts with this end Internal periphery in probe, then pop one's head in and in turn resulted in the triggering of signal by promotion, this state quilt
It is judged as that valve guide bushing is reverse, now valve guide bushing is overturn to the second avris, so that valve guide bushing is tumbled to commutation conveyer
Structure, commutation connecting gear includes two kinds of load modes, and first, commutation connecting gear itself rotates 180 degree in the horizontal plane, then make
Valve guide bushing commutates, and then forwards；Second, commutation connecting gear transmits rearward logical for valve guide bushing, and by semicircle
Track of transporting valve guide bushing is sent to the rear portion of positive connecting gear, realize the commutation of valve guide bushing, this transmit process is proper
Make valve guide bushing achieve the commutation of 180 degree, and then valve guide bushing is transmitted further along.
In the method, crucial step is that probe is carried out to the on-right angle of valve guide bushing end Internal periphery or right-angle structure
Detection, and then carry out transmitting further along forward or after turning to.The right angle of the valve guide bushing that the method is detected or non-straight corner structure
It is that valve guide bushing is met electromotor and processed using functional requirement.In contrast prior art for discriminating direction herein list
Solely the impact to electromotor overall performance that redundancy groove causes is processed to valve guide bushing, this method avoids to valve guide bushing table
Face flatness and the destruction of integrity, thus eliminate the interference to electromotor overall performance.
