Description
Technical field
This utility model relates to the dynamometry technical field of power, is specifically related to a kind of device for measuring force that can change force size continuously.
Background technology
Spring is a kind of Mechanics of Machinery component common in daily life.Being characterized within the scope of elastic deformation, the elastic force of spring is directly proportional to the deformation quantity of spring (this is Hooke's law), so the elastic force of the deformation quantity control spring of control spring can be passed through.
Bolt is also frame for movement conventional in life.It is characterized in that its move distance vertically and the angle pivoted are directly proportional.Therefore, bolt displacement on axis can be controlled by the rotation of control bolt.
Therefore, the combination of spring and bolt, it is possible to the advantage playing the two, makes it possible to continuous print and changes the elastic force (pulling force or thrust) on spring, be particularly well-suited to the measurement situation of unknown characteristics power.Such as: when confficient of static friction is measured, maximal friction is unknown, it is necessary to steady and continuous increases pulling force until just motion is thus recording maximum static friction force.Adopt this utility model device can realize stably increasing pulling force continuously until pulling, it is possible to overcome the measurement error owing to the side's of force acceleration brings.
Summary of the invention:
The purpose of this utility model is in that to provide a kind of device for measuring force that can change force size continuously, by improving force mechanism, make force size stablize controlled, can continuous and even variation, simultaneously can measure force size in real time.
In order to achieve the above object, this utility model adopts the following technical scheme that
A kind of device for measuring force that can change force size continuously, including base 1, it is fixed on the column 3 on base 1, bolt 2 through column 3 screwed hole, with bolt 2 connect clasp 4, by the ergometer 6 that universal buckle 5 is connected with clasp 4, by the spring 7 that universal buckle 5 is connected with ergometer 6, during dynamometry, spring 7 is connected with object under test.
Described ergometer 6 is digital display ergometer or weight beam.
Described bolt 2 is bolt or the leading screw of general definition, and its top is porose, garter spring, suspension ring or handle, is connected with ergometer 6 with universal buckle 5 by clasp 4；Force mechanism adopts manually or automatically.
This utility model device rationale here is that by bolt select into/screw out and change spring deformation with realizing steady and continuous, thus steady and continuous ground changes force size.The advantage of this force device for measuring force is as follows:
1. spring and bolt (bolt of general definition or leading screw) with the use of, it is achieved that steady and continuous, controllable-rate ground changes force.The degree of accuracy of force control (manually or automatically) can be designed by the pitch of the stiffness factor of spring and screw thread to be determined, adds high-precision ergometer, is greatly improved the accuracy that testing force is measured；
2. ergometer (digital display ergometer or weight beam) is measured end and is connected with force application spring, and the registration of ergometer is the force size of force application spring, it is to avoid the impact on measuring of ergometer and seating friction；
3. the effect of universal buckle is in that to avoid each parts knotting of force process, keeps force direction along the rectilinear direction at screw rod place；
4. equipment structure used by is simple, economical.
This utility model method, in the measurement of maximum static friction force and the tensile strength of bonding plane, suffers from reasonable effect.Being particularly well-suited to when unknown characteristics power is measured needs progressively to change continuously the situation that force size realizes measuring.
Accompanying drawing explanation
The force device for measuring force structural representation of this utility model of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details.
As shown in Figure 1, a kind of device for measuring force that can change force size continuously of this utility model, including base 1, it is fixed on the column 3 on base 1, through the bolt 2 of column 3 screwed hole, and the clasp 4 that bolt 2 connects, by the ergometer 6 that universal buckle 5 is connected with clasp 4, by the spring 7 that universal buckle 5 is connected with ergometer 6, during dynamometry, spring 7 is connected with object under test.
As preferred implementation of the present utility model, described ergometer 6 is digital display ergometer or weight beam.
As preferred implementation of the present utility model, described bolt 2 is bolt or the leading screw of general definition, and its top is porose, garter spring, suspension ring or handle, is connected with ergometer 6 with universal buckle 5 by clasp 4；Force mechanism adopts manually or automatically.
The force measuring method of the device for measuring force that can change force size continuously described in the utility model, comprises the steps:
Step 1: placed by object under test, spring 7 keeps relaxed state and connects object under test, it is ensured that spring 7, universal buckle 5, ergometer 6 and bolt 2 are on same straight line；
Step 2: slowly precession or back-out bolt 2, thus causing the slowly varying of spring 7 deformation quantity, namely spring tension or thrust are slowly varying；
Step 3: the measurement end of ergometer 6 is connected with spring 7 by universal buckle 5, so the registration of ergometer 6 is spring 7 and exerts a force size, Real Time Observation and record the registration of ergometer 6；
Step 4: until reaching kinestate set in advance, the registration then recording ergometer 6 now is measured value.
Such as: measure maximum static friction force time, when object just when pulled, the registration of ergometer is maximum static friction force.
