Abstract
The utility model belongs to a limiting device. One pair of gear and rack bar are engaged, both ends of the rack bar is provided with springs, a baffle plate is connected with the spring, when the rack bar do a back and forth movement, inertia force can be overcome through the spring, the rigidity collision of the mechanism is avoided, the travel range limiting of the rack bar is accurate, and the reliability of the device is improved. The utility model has the advantages of simple structure and low cost.
Description
The utility model belongs to a kind of limit stoper.
Gear drives the tooth bar linear reciprocating motion by the forward and reverse rotation of motor; when tooth bar collision limit switch; motor quits work; this hour rack walks on owing to inertia; simultaneously; clash into limiting board, general prior art adopts measures such as overload protective device break rigidly, avoids because phenomenon such as that tooth bar Location accuracy error causes greatly is stuck, gear disengaging, advancing means are out of control.This structure is poor reliability not only, complex structure, and also very high to the design and the Unit Installation requirement of tooth bar length, make troubles to the designer.
In order to solve above-mentioned deficiency, the utility model increases buffer unit, need not overload protective device, and Location accuracy is improved, and reduces the designing requirement and the installation requirement of tooth bar length, brings convenience to the designer.
The utility model is achieved in that the spacing damping device of a kind of gear rack, and spring is equipped with at the tooth bar two ends, is connected with baffle plate on the spring.When under action of inertia, during the rack linear motion, baffle plate bump limiting board, at this moment spring begins effect, and spring force increases gradually, and when equating with inertial force, tooth bar is stop motion just.Tooth bar reversing motion in like manner also is like this.
The utility model has the advantages that compared with prior art not only tooth bar length dimension and installation requirement thereof are not high, and good reliability, and be simple in structure, cost is low.
Further specify below in conjunction with embodiment
Fig. 1: the utility model schematic representation
Fig. 2: embodiment's schematic representation.
Referring to Fig. 1 and Fig. 2, described baffle plate (4) can be made tooth bar (5), and when gear (3) when being rotated counterclockwise by motor driving, tooth bar (2) moves right, during to spacing, the motor outage, because the inertia of driving mechanism, main tooth bar (2) still continues motion to the right, auxiliary gear (5) bump limiting board, spring (1) compression, spring force and be used to power and equate main tooth bar (2) stop motion gradually.Equally, main tooth bar (2) back its working principle of moving is identical.
In addition, one restraining groove is arranged, on main tooth bar (2), position limit pin is housed, pay the limit position of tooth bar (5) with restriction in pair tooth bar (a 5) side.
Owing to this device is provided with spring and pays a tooth bar, when main tooth bar moved to end points, its inertial force obtained buffering, thereby did not cause mechanism's ten million rigid damage, also can not make main tooth bar can't do reversing motion because of gear and the disengaging of main tooth bar.
Claims (2)
1, the spacing damping device of a kind of gear rack, the wheel and rack engagement, it is characterized in that: spring (1) is equipped with at the tooth bar two ends, is connected with baffle plate (4) on the spring.
2, by the described damping device of claim 1, it is characterized in that: baffle plate (4) can be made tooth bar (5).
