Description
Technical field
The utility model relates to a kind of pick-up unit, is specifically related to a kind of device that motorcycle engine shift fork α angle is detected.
Background technology
Shift fork is the ingredient of motorcycle selector gear, it is assembled together shift fork by declutch shift shaft, and the shift shift fork is installed on the shift drum, and the rotation of dependence shift drum realizes the axial move left and right of shift fork, thereby the gear that obtains the different numbers of teeth combines, to realize different rotating speeds.With C100 is example: two shift forks are housed on the shift drum, respectively on main shaft and the countershaft movably gear horizontally slip, a shift fork horizontally slips and can finish two gears, two shift forks can be finished the speed change of four gears.The move left and right of shift fork is to slide in the helicla flute that relies on the shift drum outer round surface to finish.The variation size of shift fork angle (being the α angle) directly influences the normal operation of variable transmission mechanism.If the shift fork angle is incorrect, will causes phenomenons such as shift is ineffective, job-hopping, thereby injure people's safety.In view of the importance at shift fork α angle, just essential to its whether qualified detection.Traditional detection means is that cubing is provided with the centering spindle corresponding with the shift fork mounting hole according to drawing design cubing, and cubing is provided with and the shift fork corresponding groove simultaneously.During detection, directly shift fork to be checked is enclosed within the centering spindle, observes shift fork and whether can fall in the groove on the cubing, if can fall into and show that shift fork is qualified, on the contrary then defective.Adopt this cubing, inefficiency detected needs about 7 minutes, so can only inspect by random samples at present, and cost can increase no concrete data after detecting, the result only for meeting cubing and not meeting cubing, can not reflect the extent of deviation at shift fork α angle, is unfavorable for follow-up improvement.
The utility model content
At existing motorcycle engine shift fork α angle detecting device above shortcomings, a kind of high-level efficiency that the purpose of this utility model provides, can reflect the concrete motorcycle engine shift fork α angle detecting device that detects numerical value.
The technical solution of the utility model is achieved in that engine shift fork pick-up unit, comprise base, on base, be provided with the shift fork positioning core axle, guide rail and pressing head seat, the three at same straight line and guide rail between shift fork positioning core axle and pressing head seat, shift fork positioning core axle and shift fork mounting hole are to being applied to locate shift fork, guide rail is provided with can be along the locating piece of its slip, locating piece is provided with circular arc over against shift fork positioning core axle one end and decides core print, pressing head seat is provided with horizontal movable pressure head, laterally the pressure head and the locating piece other end make circular arc decide core print when being applied to detect shift fork is compressed, at the other sensor that is provided with induction shift fork microcephaly rotation amplitude to be measured of shift fork positioning core axle, sensor is connected with the electric weight instrument.
Further improve being, be provided with by another pressing head seat on the base be used for from above vertical movable pressure head that shift fork to be measured is compressed.Described shift fork positioning core axle is three covers, and is installed on relevant position on the base to select a mode (promptly can be selectively with wherein a cover).
Compared to existing technology, the utlity model has following advantage:
1, detecting one only needed for 7 seconds, and efficient increases substantially, and can satisfy the online detection of flow production line fully, and the sampling observation before becoming is full inspection, can control the quality of shift fork more effectively.
2, testing result accurately and reliably, come into plain view, and can reflect intuitively that shift fork α angle departs from the scope of standard value, help follow-up improvement.
3, the α angle of the cover of three on engine shift fork I, II, III can only be finished on a cover pick-up unit, has saved the checkout equipment manufacturing cost.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model engine shift fork pick-up unit comprises base 1, is provided with shift fork positioning core axle 2, guide rail 3 and horizontal pressing head seat 4 on base 1, the three at same straight line and guide rail 3 at shift fork positioning core axle 2 with laterally between the pressing head seat 4.Shift fork positioning core axle 2 and shift fork mounting hole are to being applied to locate shift fork, guide rail 3 is provided with can be along the locating piece 5 of its slip, locating piece 5 sides are provided with drawing handle 6, by stirring drawing handle 6 locating piece 5 is slided along guide rail 3, locating piece 5 is provided with circular arc over against shift fork positioning core axle 2 one ends and decides core print 7.When shift fork is detected and locating piece contour, described shift fork positioning core axle 2 is located on the base 1 by substrate 8.Laterally pressing head seat 4 is provided with horizontal movable pressure head 9, and laterally pressure head 9 and locating piece 5 other ends make circular arc decide core print when being applied to detect shift fork is compressed.At the shift fork positioning core axle 2 other sensors 10 that are provided with induction shift fork microcephaly rotation amplitude to be measured, sensor 10 is connected with electric weight instrument 11.
For prevent shift fork location back along the shift fork positioning core axle up and down play influence testing result, the utility model passes through another vertical hold down gag 12 on base 1, compress from the top with shift fork to be measured.
Because the shift fork on the engine is generally three, to detect respectively, based on this, shift fork positioning core axle of the present utility model is three covers, corresponding with three shift forks respectively, leave with it corresponding installation site on base, each position is provided with corresponding mounting hole, and selectively wherein a cover be installed on relevant position on the base.According to detecting needs, original shift fork positioning core axle can be taken off and change a cover that will detect, realized sharing of pick-up unit thus, reduction device fabrication cost.
Detection principle of the present utility model: the utility model adopts pressure head with semicircle bore area location with shift fork installation axle hole location, and the shift fork microcephaly rotates around the shift fork positioning core axle in position fixing process, thereby the probe that promotes sensor is flexible, pendulum angle is big more, and is flexible big more, detects thus.
Testing process of the present utility model: at first the school zero, is about to angular standard part 13 and is put in the 2 enterprising column criterion check and correction of shift fork positioning core axle, adjusts electric weight instrument 11 electron beam is shown just in time at zero point.Behind the school zero, take off the angular standard part, change shift fork to be measured, it is compressed by vertical hold down gag 12.Stir the handle 6 on the locating piece, make circular arc decide core print 7 and enter shift fork semicircle endoporus, decide core print 7 by circular arc and make center of arc, by horizontal pressure head 9 circular arc is decided core print 7 again and compress with shift fork.In position fixing process, the shift fork microcephaly rotates around shift fork positioning core axle 2, and 10 of sensors are directly measured rotational angle, this result passes to electric weight instrument 11 again, the electric weight instrument shows the result that with the form of electron beam the testing staff just can judge that directly whether qualified product is according to the demonstration of electron beam.
