Description
Technical field
The utility model is mainly concerned with biscuit appearance field, refers in particular to a kind of stroke sensor that is applicable to fixed biscuit appearance.
Background technology
In fixed biscuit appearance, often need use stroke sensor.The trip sensor is to be fixed on a bucket wheel machine travel section deciliter right position through holder to put, and synchronizing wheel is advanced on the operation guide rail.When bucket wheel machine moves, will drive synchronizing wheel and rotate synchronously, will be rotationally connected to photoelectric encoder through driving shaft, photoelectric encoder is gathered the synchronizing wheel rotation information, draws the bucket wheel machine travel distance through calculating the synchronizing wheel girth.
In above-mentioned traditional stroke sensor; Synchronizing wheel is to reach the purpose that is pressed on the guide rail through the synchronizing wheel dead weight, in case its hinge portion is dumb a bit, just possibly cause synchronizing wheel unsettled on guide rail; Photoelectric encoder is got less than run-length data, causes the biscuit failure.Simultaneously, because of biscuit appearance frequency of utilization is not high, therefore there is no need synchronizing wheel is moved on guide rail, photoelectric encoder is in detected state always.
The utility model content
The technical matters that the utility model will solve is: to the technical matters that prior art exists, the utility model provide a kind of simple and compact for structure, easy to operate, can improve accuracy of detection, prolong the stroke sensor that is used for fixing formula biscuit appearance of whole service life.
In order to solve the problems of the technologies described above, the technical scheme that the utility model proposes is:
A kind of stroke sensor that is used for fixing formula biscuit appearance; Comprise holder and be coaxial shape and be installed on synchronizing wheel and photoelectric encoder on the bracing frame; The connecting rod that is arranged with on the support frame as described above more than two also can slide along connecting rod; The top of said connecting rod is connected on the upgrade block, offers threaded hole on the said upgrade block and promotes screw mandrel and be connected through threaded engagement with one, and said lifting screw mandrel is installed on the holder and in the end of lifting screw mandrel and is provided with the lifting knob.
Further improvement as the utility model:
Said connecting rod is the screw mandrel with screw thread, and said screw mandrel is provided with lock-nut, is provided with tensioning spring between said lock-nut and the bracing frame.
Said upgrade block is provided with the guide rod more than, and said holder is provided with the pilot hole that cooperates in guide rod.
Said holder is provided with and is used for and promotes the thread segment that screw mandrel cooperates, and said lifting screw mandrel is sheathed in the thread segment.
The through hole of offering on the bracing frame is passed in the bottom of said connecting rod, leaves distance between the bottom end face of said connecting rod and the bracing frame.
Compared with prior art, the advantage of the utility model is:
1, the synchronizing wheel in the utility model has enhanced feature, can synchronizing wheel be lifted from guide rail under the situation of feasible not biscuit, reduces the transportation load of synchronizing wheel and photoelectric encoder, prolongs its serviceable life; Simultaneously, promote knob and adopted forward and reverse screw thread, range of lift amplifies at double, just can synchronizing wheel be lifted from guide rail very apace, can effectively save the time that turn promotes knob, and is easy to operate.
2, adopt tensioning spring in the utility model, the elastic force through tensioning spring adds that the deadweight of synchronizing wheel itself can make synchronizing wheel fit on the track all the time, rises and falls even if track is a height, and both cooperations also can remain at optimum condition.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
As shown in Figure 1; The utility model is used for fixing the stroke sensor of formula biscuit appearance; Comprise holder 7 and be coaxial shape and be installed on synchronizing wheel 2 and photoelectric encoder 10 on the bracing frame 3; Synchronizing wheel 2 is slidedly arranged on the guide rail 1, links to each other through driving shaft 9 between synchronizing wheel 2 and the photoelectric encoder 10, and 7 of holders are fixed on the advance correct position of part of bucket wheel machine.In the utility model; The connecting rod 5 that is arranged with on the bracing frame 3 more than two also can slide along connecting rod 5; The top of connecting rod 5 is connected on the upgrade block 6; Offer threaded hole on the upgrade block 6 and promote screw mandrel 11 and is connected, promote screw mandrel 11 and be installed on the holder 7 and and be provided with lifting knob 8 in the end of lifting screw mandrel 11 through threaded engagement with one.When rotary lifting knob 8, can be with upgrade block 6 and bracing frame 3, synchronizing wheel 2 whole moving, realize; Make and under the situation of biscuit not, can synchronizing wheel 2 be lifted from guide rail 1, reduce the transportation load of synchronizing wheel 2 and photoelectric encoder 10, prolong its serviceable life.
In the present embodiment, connecting rod 5 is for having the screw mandrel of screw thread, and screw mandrel is provided with lock-nut 12, is provided with tensioning spring 4 between lock-nut 12 and the bracing frame 3, and the top of connecting rod 5 then is fixed on the upgrade block 6 through set nut.The through hole of offering on the bracing frame 3 is passed in the bottom of connecting rod 5, leaves distance between the bottom end face of connecting rod 5 and the bracing frame 3, promptly is reserved with one section lifting travel.Carry out biscuit when work, the elastic force through tensioning spring 4 adds that the deadweights of synchronizing wheel 2 itself can make synchronizing wheel 2 fit in all the time on the guide rail 1, rises and falls even if guide rail 1 is a height, and both cooperations also can remain at optimum condition.Simultaneously,, can adjust the pretension elastic force of tensioning spring 4 at any time, so just can effectively avoid the unsettled situation of synchronizing wheel 2 through lock-nut 12.
In the present embodiment, upgrade block 6 is provided with the guide rod 13 more than, and holder 7 is provided with the pilot hole 14 that cooperates with guide rod 13, the reliability when guaranteeing to promote with cooperating of pilot hole 14 through guide rod 13.
In the present embodiment, holder 7 is provided with and is used for and promotes the thread segment that screw mandrel 11 cooperates, and promotes screw mandrel 11 and is sheathed in the thread segment.Promote knob 8 and adopt forward and reverse screw thread, this forward and reverse screw thread is meant and comprises the two sections screw thread that one is left-hand thread (LHT); Another is a right-hand thread, because two screw threads are opposite, so the distance of its lifting that rotates a circle is exactly two pitch S=P1+P2; Therefore range of lift amplifies at double; Just can synchronizing wheel 2 be lifted from guide rail 1 very apace, can effectively save the time that turn promotes knob 8, easy to operate.
Below only be the preferred implementation of the utility model, the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be pointed out that for those skilled in the art,, should be regarded as the protection domain of the utility model in the some improvement and the retouching that do not break away under the utility model principle prerequisite.
