Abstract
The utility model is a piezoelectric sensor loading mechanism; a piezoelectric sensor is sleeved on a screw rod; one end of the screw rod is fixedly connected with a measuring mechanism; the other end of the screw rod is connected with a compression block through thread; the compression block is used for the precession pressure applying. The piezoelectric sensor loading mechanism is structurally characterized in that the compression block is a cylinder whose size is almost the same as the compression end surface of the piezoelectric sensor; the compression block is threaded through the through hole on an installation base; a locking ring is clamped on the upper part of the compression block; locking screws are arranged around the locking ring which is connected with the installation base. Compared with the prior art, the piezoelectric sensor loading mechanism has the advantages of simple structure, easy manufacturing and good loading effect so that the loss of the force transmitted to the sensor is reduced by about 25 percent and the authenticity of the measurement data of the device is greatly improved.
Description
Technical field
The utility model is a kind of piezoelectric sensor load maintainer, belongs to the technical field of structures of product.
Background technology
In at present domestic and international dynamic balancer dynamic balancing measurement, all used piezoelectric sensor, wherein the prestrain mode of sensor adopts the stud nut fixed form.This method is that piezoelectric sensor is placed between measuring mechanism and the fixed mount, connects with the screw bolt and nut mode.Axially load by rotatablely moving of nut.The problem that this load mode occurs easily is when measuring after the loading, the part power of out-of-balance force is not directly delivered on the fixed mount by bolt and nut by piezoelectric sensor, the power of the highest meeting loss about 30% causes measurement data distortion even invalid.
Summary of the invention
The problem that exists at existing apparatus just with the purpose of this utility model and design a kind of piezoelectric sensor load maintainer is provided, it can reduce the loss of suffered power on the sensor in the transmittance process of power, thereby improves the authenticity that detects data.The power of the highest loss 5% of this mechanism.
The objective of the invention is to realize by following measure:
This kind piezoelectric sensor load maintainer, piezoelectric sensor is sleeved on the screw rod, one end of screw rod screw rod is fixedly connected on the measuring mechanism, the pressurizing block that the other end is exerted pressure by screw thread and precession is connected, its structural design features is: pressurizing block is one and the sizable right cylinder of piezoelectric sensors end face, pass through hole on the mount pad, its top clamps a retaining ring, is provided with lock-screw around the retaining ring and is connected with mount pad.
In the said mechanism, the through hole between pressurizing block and the mount pad has certain clearance, and its end face compresses piezoelectric sensor and pins with screw.Pressurizing block can be pressurizeed with outer six sides or interior hexagonal spanner.This mechanism and measuring mechanism with after piezoelectric sensor and subsidiary bolt thereof are connected, just can have been added preload to sensor.

Embodiment
Below with reference to drawings and Examples the utility model is further described:
Shown in accompanying drawing 1～4, this kind piezoelectric sensor load maintainer, piezoelectric sensor 4 is sleeved on the screw rod 6, one end of screw rod screw rod 6 is fixedly connected on the measuring mechanism 5, the pressurizing block 2 that the other end is exerted pressure by screw thread and precession is connected, pressurizing block 2 is one and the sizable right cylinder of piezoelectric sensor 4 pressurized end faces, cylindrical end face is pressed on the piezoelectric sensor 4, right cylinder passes through hole 7 on the mount pad 1, its top clamps a retaining ring 8, is provided with lock-screw 3 around the retaining ring 8 and is connected with mount pad 1.
This mechanism loading method is a rotation pressurizing block 2, eliminate the gap between measuring mechanism 5, piezoelectric sensor 4 and the mount pad 1, continue rotation, increase preloads, load the monitoring voltage of size by conversion, when voltage reaches predetermined value, stop to load, pin pressurizing block 2 by retaining ring 8, keep the load of piezoelectric sensor constant with screw 3.
The utility model mechanism compares with existing apparatus and has the following advantages: simple in structure, easy system Make, load effectively, the loss by sensor force is reduced about 25%, improved greatly and established The authenticity of standby measurement data.
