Notice of authorization day is on October 8th, 2008, application number is 2004800184283 patent, a kind of rack-and-pinion transmission device with brake unit is provided, it is provided with a brake unit on the balladeur train of fixing small gear, this brake unit comprises braking small gear, braking housing and brake rotors, by the small gear of brake unit is engaged with tooth bar, realizes fixing tooth bar and balladeur train.Its brake unit adopts drive motor to drive, and structure is comparatively complicated, and the position between brake unit and tooth bar is relative fixing, and when brake unit is not worked, it still needs to be fixed on balladeur train, occupies working space.
Summary of the invention
For addressing the above problem, the invention provides a kind of mechanical stop limiter simple in structure, easy to use, can be directly used in fixing in tooth bar installation or maintenance process.
Mechanical stop limiter of the present invention, comprises claw main body, locking block, pushing block, spring and be positioned at the cylinder on claw main body top, and claw body interior is provided with holding channel I, locking block holding channel II and the spring holding cavity of limited workpiece; Holding channel II is communicated with spring holding cavity and holding channel I, and locking block is fixedly connected with spring by pushing block, and the other end of spring is fixed on spring holding cavity top; Spring holding cavity top is provided with cylinder connecting rod through hole, and cylinder connecting rod is fixedly connected with pushing block through the spiral hole of through hole and spring.
Cylinder ventilation, cylinder connecting rod is applied on pushing block, and then promotes locking block and need engage by fixing tooth bar, realizes spacing; When installing or having overhauled, cylinder is oppositely ventilated, and locking block is separation with rack guide rail under cylinder acts on spring simultaneously.
As one, improve, described mechanical stop limiter also comprises tooth bar, and tooth bar is fixedly connected with holding channel I, between tooth bar and holding channel II, has space.During use, one end of tooth bar connects needs spacing slide block, at slide block, needs fixed position, starts air cylinder air source and can realize fixing slide block.
Preferably, the locking mechanism of described locking block is sawtooth, can be by the stationary rack more firm with engaging of tooth bar sawtooth.
Described spring is stretched spring.
Compared with prior art, the invention has the beneficial effects as follows: simple in structure, the position that takes up room is little, be convenient to install, overhaul; When not using, this limit stoper can be taken off and deposits, not take tooth bar working space, easy to use; Also tooth bar can be fixed on other parts that need brake, realize the braking to other brake members, and the cost of limit stoper be low, maintenance cost is little.
