Technical matters to be solved by this invention is: overcome the deficiencies in the prior art, a kind of reasonable in design, easy to use, high efficiency is provided and measures torque meter for torsional spring accurately.
Technical scheme of the present invention is: a kind of torque meter for torsional spring, contain base and column, described column lower end is connected with described base upper end, be set with upright post sleeve on described column, be provided with latch mechanism between described upright post sleeve and column, described base is provided with hollow cavity, be placed with weighing apparatus in this hollow cavity, be provided with opening on described base upper chambers wall, this opening part is placed with force-transmitting block, described force-transmitting block lower end contacts with described weighing apparatus, is provided with two limited posts on described force-transmitting block; Described upright post sleeve is connected with rack tube, is set with tooth bar in described rack tube, and the described tooth bar gear interior with being fixed on rack tube is meshed, and wheel shaft one end of described gear is fixed with handle set, on described handle set, handle is installed; Described tooth bar lower end is connected with shaft collar, is provided with compression bar on described shaft collar, and described base upper end is fixed with display and fixed mount, is provided with displacement transducer on described fixed mount, and described displacement transducer is connected with described display by line.
Be provided with lock-screw on described handle set.Described weighing apparatus is the digital electric weighing apparatus.Described gear is circular gear or sector gear.Described upright post sleeve and rack tube are the integral type structure.
The invention has the beneficial effects as follows:
1, the present invention improves with common spring tension and compression testing machine, does a simple frock (force-transmitting block) according to the shape of torsion spring, and torsion spring is fixed on frock, use the handle tension and compression, can read accurately and quickly torque value, easy to use, be applicable to batch production.
2, frock of the present invention can adopt multiple different structure, and the torsion spring that can be suitable for the different structure shape is measured moment of torsion, uses very convenient.
3, the present invention adopts displacement transducer accurately to control the distance of tension and compression torsion spring, and the displacement in the time of can guaranteeing at every turn to measure is identical, thereby guarantees accuracy and the consistance of measurement.
4, the present invention adopts weighing apparatus can show intuitively the torsion that torsion spring produces when reversing certain angle, and then can measure the moment of torsion of this torsion spring.In addition, display can show the numerical value of displacement transducer, can also show the measurement numerical value of weighing apparatus, intuitive and convenient.
5, reasonable in design, easy to use, the high efficiency of the present invention and measuring accurately, it is applied widely, and after promoting, comprehensive benefit is good.
Four, description of drawings:
