Abstract
The utility model relates to a mechanical stroke measuring device, which relates to an engineering machinery part, and solves the problems that the existing technical structure is not reasonable and measurement accuracy is poor. The mechanical stroke measuring device provided by the utility model is characterized by comprising a gear assembly and a rack assembly, wherein the gear assembly comprises a junction plate, a hinge with a spring, an encoder and a shaft gear; the shaft of the shaft gear is vertically arranged; the gear of the shaft gear is horizontally arranged at the lower end of the shaft; the encoder is arranged at the other end of the shaft; the junction plate is connected with the encoder and the shaft gear through the hinge with the spring, and the junction plate is connected with a movable body; and the rack assembly comprises a rack and a rack base, wherein the rack base is arranged on an object which is relatively dormant with the movable object, the rack is fixed on the rack base, and the gear is meshed with the rack. The mechanical stroke measuring device provided by the utility model has the advantages of reasonable structural design and accurate measurement, and is convenient for installation.
Description
Technical field
The utility model belongs to the parts of engineering machinery, relates to the supporting stroke measuring device of a kind of engineering machinery.
Background technology
At present, engineering machinery supporting stroke measuring device adopt wheel to add coder structure, equip the detection method that can be used as device travel behind this measurement mechanism.Normally used stroke measuring device, as shown in Figure 4, its structure is: scrambler 3 is fixed on the rotary body (wheel 7) of motion, calculates the stroke of moving object through the revolution that calculates rotary body.Prior art shortcoming be: 1, because scrambler is contained on the rotor, and there is the possibility skid in rotor, so scrambler can not reflect the real motion state of movable body.2, after wheel was through one section operation, diameter can produce wearing and tearing, the accuracy (cumulative errors) that influence is measured.3, the machining precision of rotary body is high.4, because the scrambler installation site can only cause the wheel width to increase in the axletree end, can produce with other object and interfere.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that prior art exists, and a kind of mechanical trip measurement mechanism is provided, and solves existing stroke measuring device unreasonable structure, measures poor accuracy, the technical matters that manufacturing cost is high.
The utility model is realized through following technical scheme:
A kind of mechanical trip measurement mechanism; It is characterized in that: said stroke measuring device is made up of gear assembly and tooth bar assembly; Said gear assembly is made up of hinge, scrambler and the shaft gear of web joint, band spring, and the axle of said shaft gear vertically is provided with, and the gear of said shaft gear is horizontally set on the lower end of said axle; Said scrambler is installed in the other end of said axle, and the hinge of said band spring links together said web joint and described scrambler and said shaft gear; Said web joint is connected with movable body; Said tooth bar assembly is made up of tooth bar and tooth bar pedestal, said tooth bar pedestal be installed in the static relatively object of moving object on, said tooth bar is fixed on the said tooth bar pedestal; Said gear and the engagement of said tooth bar.
The utility model compared with prior art has the following advantages and beneficial effect:
1, the utility model is independent of kinematic train, does not receive the influence of main transmission rotary body, measures accurately.
2, when movable body does not move along a straight line, because gear is contained on the hinge of band spring, allow movable body relative stationary object when vertically moving that certain transversal displacement is arranged, can not influence the normal engaged of rack-and-pinion, reasonable in design.
3, the installation site can be multi-faceted, the convenient installation.
4, rack-and-pinion does not have foreign matter and has between cog for being horizontally disposed with, and guarantees the normal engaged of rack-and-pinion.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the side view of Fig. 1;
Fig. 4 is the prior art constructions synoptic diagram.
The utility model is elaborated through preferred embodiment below in conjunction with accompanying drawing.
Embodiment
A kind of mechanical trip measurement mechanism; Form by gear assembly and tooth bar assembly; Said gear assembly is made up of hinge 2, scrambler 3 and the shaft gear 4 of web joint 1, band spring, and the axle 4-1 of said shaft gear 4 vertically is provided with, and the gear 4-2 of said shaft gear 4 is horizontally set on the lower end of said axle 4-1; Said scrambler 3 is installed in the other end of said axle 4-1, and the hinge 2 of said band spring links together said web joint 1 and described scrambler 3 with said shaft gear 4; Said web joint 1 is connected with movable body; Said tooth bar assembly is made up of tooth bar 5 and tooth bar pedestal 6, said tooth bar pedestal 6 be installed in the static relatively object of moving object on, said tooth bar 5 is fixed on the said tooth bar pedestal 6; Said gear 4-2 and 5 engagements of said tooth bar.
The installation process of the utility model: earlier scrambler 3 is sleeved on the gear shaft 4, the hinge 2 with the band spring links together web joint 1 and scrambler 3 and shaft gear 4 again; Then tooth bar 5 is fixed on the resting, the gear 4-2 with shaft gear 4 is meshed with tooth bar 5 again, and gear assembly is fixed on the mobile object, arrange in position, i.e. and the installation of finishing device, and then be aided with necessary electrical control.
During operation; The relative stationary object of mobile object is subjected to displacement; Meanwhile the mobile object driven gear is with respect to the tooth bar rotation that is loaded on the stationary object; The distance that gear moves with respect to tooth bar is the displacement of mobile object, and the revolution of gear is realized stroke measurment through the conversion entering electric control system of scrambler.
