Description
Technical field: the utility model relates to a kind of product testing system, and especially a kind of following loading system belongs to the Test And Check Technology field.
Background technology: load test equipment is widely used at industrial circle.Conventional loading form is loaded as the master with orientation, also has with the fixed mode loading of changing direction.When loading direction need to change according to the characteristic of part, the loading direction right and wrong were fixed mode, and the self gravitation that loads like this cylinder can exert an influence to loading system, has reduced loading accuracy.How a kind of backup system being provided, can loading the moment that the cylinder deadweight produces by Real-time Balancing, is the technical barrier that those skilled in the art need to solve.
The utility model content: for above-mentioned the deficiencies in the prior art, the utility model provides a kind of loading cylinder dead-load moment balance device, can load the moment that the cylinder deadweight produces by active balance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of loading cylinder dead-load moment balance device comprises loading cylinder, the rotary encoder of reaction frame, inbuilt displacement sensor and is being connected the oscillating motor of torque sensor.The loading cylinder of inbuilt displacement sensor is arranged on reaction frame by axle, at an end of axle, rotary encoder is installed, and the other end is installed the oscillating motor that is connecting torque sensor.The loading cylinder of inbuilt displacement sensor provides element to connect with the moment of torsion that is being connected torque sensor.
Preferably, the loading cylinder of inbuilt displacement sensor is arranged on reaction frame by joint spider, in the joint spider both direction each to an end rotary encoder is installed, the other end is installed the moment of torsion that is connecting torque sensor element is provided.
Preferably, element is provided is servomotor or oscillating motor to described moment of torsion.
The utility model is simple in structure, and is easy to use, and effectively Real-time Balancing loads the moment that the cylinder deadweight produces.
Description of drawings:
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment:
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clear, intactly description, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Give the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1: a kind of loading cylinder dead-load moment balance device comprises loading cylinder 2, the rotary encoder 4 of reaction frame 1, inbuilt displacement sensor and the oscillating motor 3 that is being connected torque sensor.The loading cylinder 2 of inbuilt displacement sensor is arranged on reaction frame 1 by axle, at an end of axle, rotary encoder 4 is installed, and the other end is installed the oscillating motor 3 that is connecting torque sensor.The loading cylinder 2 of inbuilt displacement sensor connects with the oscillating motor that is being connected torque sensor 3.
The loading cylinder 2 of inbuilt displacement sensor moves to the optional position, space, and the displacement sensor that loads in cylinder loads the length that cylinder stretches out, and rotary encoder 4 is measured the angle that hydraulic cylinder swings simultaneously.By above two parameters, system automatically calculates and loads the moment of torsion that cylinder keeps current location to need, and the oscillating motor 3 that is connecting torque sensor is carried out the moment closed-loop control, thereby makes loading cylinder 2 keep balance in any position in the space.When the angle that loads cylinder 2 and length change, system calculates the change output torque in real time, thereby keeps in real time balance.
Therefore, the loading cylinder dead-load moment balance device that the utility model provides can in plane mechanism, according to the overhang and the corner that load cylinder, load the cylinder dead-load moment by the oscillating motor self-poise that is connecting torque sensor.
As shown in Figure 2: a kind of loading cylinder dead-load moment balance device comprises loading cylinder 2, joint spider 5, the rotary encoder 4 of reaction frame 1, inbuilt displacement sensor and the servomotor 6 that is being connected torque sensor.The loading cylinder 2 of inbuilt displacement sensor is arranged on reaction frame 1 by joint spider 5.In joint spider 5 both directions each to an end rotary encoder 4 is installed, the other end is installed the servomotor 6 that is connecting torque sensor.
The loading cylinder 2 of inbuilt displacement sensor moves to the optional position, space, and the displacement sensor that loads in cylinder loads the length that cylinder stretches out, and two rotary encoders 4 are measured the angle that hydraulic cylinder swings simultaneously.By above three parameters, system automatically calculates and loads the diaxon moment of torsion that cylinder keeps current location to need, and the servomotor 6 that is connecting torque sensor is carried out the moment closed-loop control, thereby makes loading cylinder 1 keep balance in any position in the space.When the angle that loads cylinder 2 and length change, system calculates the change output torque in real time, thereby keeps in real time balance.
Therefore, the loading cylinder dead-load moment balanced system that the utility model provides can in three dimensions, according to the overhang and the corner that load cylinder, load the cylinder dead-load moment by the oscillating motor self-poise that is connecting torque sensor.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from marrow or the scope of utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
