Abstract
The utility model provides a weighing sensor device of a mass center measuring device. The weighing sensor device is characterized in that a weighing sensor is installed on the bottom face of a measuring platform and ascends and descends with the measuring platform, so that relative position of the weighing sensor and the measuring platform is fixed, the problem that the relative position of the weighing sensor and an object to be measured is not fixed due to the fact that the weighing sensor is fixedly installed on a basic platform in the traditional installation mode is resolved, and an effect of fall point position deviation on measuring results is removed. In addition, the weighing sensor well ensures that the weighing sensor is stressed along the center axis and avoids moment deviation signal effects caused by the fact that the weighing sensor is stressed in the direction deviating from the center axis.
Description
Technical field:
The utility model belongs to industrial barycenter field of measuring technique, is specifically related to a kind of weighing and sensing apparatus of barycenter measuring equipment.
Technical background:
Present known its principle of work of barycenter testing apparatus, mostly be to adopt to decide span (distances between two sensors of vertical axis) LOAD CELLS carrying measured object, calculate object mass center device coordinate position with sensing data according to the equalising torque measuring method, try to achieve the object mass center coordinate by the coordinate system conversion again.The LOAD CELLS of this kind equipment is installed on the fixed basic platform, and its mounting means has two kinds, respectively such as Fig. 1 and 2.Fig. 1 mode, manometric head 2 are installed on the LOAD CELLS 1, and measuring table 5 is the plane with manometric head 2 as use.Testee 6 descends under the effect of elevating mechanism 3 with measuring table 5 during work, by manometric head 2 normal pressure is acted on the LOAD CELLS 1 along center sensor.The calculating of barycenter is directly related with half span parameter D (the measured object center is to the distance at manometric head center), in this LOAD CELLS mounting means, because the manometric head trail force load position based was not fixed (reality is the disc of certain radius) after measuring table descended, cause actual half span parameter to become D+ Δ D by D, such as Fig. 3, thereby the barycenter measurement result is brought error.For Fig. 2 mode, manometric head 2 is installed on the measuring table 5, the pressure that LOAD CELLS 1 is transmitted by planes carry manometric head 2 during work.This mode, although half span parameter D is definite value, such as Fig. 4, but same reason, because the manometric head trail force load position based is unfixing, cause the normal pressure of 5 pairs of LOAD CELLS 1 of measuring table to depart from center sensor (operating distance becomes L+ Δ L by L), this will introduce an inclined to one side square signal M for LOAD CELLS, thereby also the barycenter measurement result is brought error.D refers to that the measured object center is to the distance at manometric head center.L refers to that the measured object center is to the distance of center sensor.
The purpose of technological invention:
In the barycenter measuring equipment, the error effect that brings because of existing LOAD CELLS mounting means, the utility model provides a kind of weighing and sensing apparatus, and it can effectively eliminate LOAD CELLS drop point site deviation and the partially impact that brings of square signal, thereby improves measuring accuracy.
Technical scheme:
The mode that the invention for solving the technical problem is taked is: LOAD CELLS is shifted being installed on the measuring table 5 by basic platform 4, simultaneously manometric head 2 is installed on the LOAD CELLS 1.Like this, just be fixed up with respect to measuring table to the distance between the pressure-acting point in measuring table measured object center, remains constant in measuring table lifting measuring process, thereby eliminated the impact that the drop point site deviation causes measurement result.In addition, manometric head 2 is installed on the LOAD CELLS 1, has guaranteed that normal pressure all the time by the center of LOAD CELLS 1, avoided the appearance of inclined to one side square signal, thereby also eliminated the impact that inclined to one side square signal causes measurement result.
The beneficial effects of the utility model are: eliminated existing barycenter measuring equipment LOAD CELLS, the drop point site deviation of bringing and inclined to one side square signal have improved measuring accuracy to the impact that measurement result causes.The technical program is particularly useful for the barycenter equipment of high-acruracy survey.

Embodiment:
Shown in Fig. 5,6, LOAD CELLS 1 is installed on the bottom surface of measuring table 5, and manometric head 2 is installed on the LOAD CELLS 1.Its process and method are: the first step, on the bottom surface of measuring table 5, accurately process pilot hole by design attitude, and by the pin-and-hole part that is connected LOAD CELLS 1 is installed on the measuring table 5; Second step is processed into cone point or small arc-shaped cone point to manometric head 2 front ends (with basic platform 4 contact jaws), guarantees that its cone point (or cone dot center) crosses its axial line; The 3rd step, manometric head 2 is installed on the LOAD CELLS 1, like this, measuring table measured object center just is defined as fixed value to distance between the pressure-acting point, in this case, even the position of pressure-acting point on the basic platform action plane changes to some extent, but the result of calculation of barycenter is had no effect.On the other hand, because normal pressure all the time by the axle center of LOAD CELLS, the phenomenon of inclined to one side square signal can not occur again.So the utility model weighing and sensing apparatus has fundamentally been eliminated the impact that drop point site deviation and inclined to one side square signal phenomenon cause measurement result.
