Abstract
The utility model provides a back-arch type pressure gauge, which is composed of a strain gage, supporting blocks, a force receiving block and a back arch, wherein the back arch 1 is an piece of arch-shaped spring steel, the back arch 1 can only deform slightly, when a force applying test piece is applying a pressure to the force receiving block 3 from the outer side of the back arch 1, the force applying test piece cannot touch the strain gage 2, a force receiving test piece cannot touch the strain gage 2, the slight deformation generated by pressing the back arch 1 is converted into a strain of the strain gage 2 completely, and the pressure applied on the force receiving test piece by the force applying test piece can be accurately measured by measuring the strain of the strain gage 2. The back-arch type pressure gauge has the advantages that the strain gage 2 is not in contact with the force receiving test piece or with the force applying test piece, and the installation is convenient.
Description
(1) technical field
The present invention relates to a kind of device for measuring force, belong to a kind of contactless device for measuring force.
(2) technical background
Measuring mutual pressure between some machinery, can not paste sensor at stressed test specimen, can not paste sensor at application of force test specimen, otherwise not be that sensor is damaged, is exactly the measurement result distortion.
(3) summary of the invention
The purpose of this utility model provides a kind of contactless pressure device for measuring force.
The purpose of this utility model is to realize like this, it contains foil gauge, back-up block, force block, it is characterized in that: also contain back of the body bow, back of the body bow 1 is the spring steel of a tortuous bow shape, the two ends of back of the body bow 1 are back-up blocks 4, the centre in back of the body bow 1 outside is force block 3, and foil gauge 2 closely sticks on the inboard of back of the body bow 1.
When application of force test specimen was exerted pressure to force block 3 from back of the body bow 1 outside, application of force test specimen can not touch foil gauge 2, and back of the body bow 1 can only have small distortion, and stressed test specimen can not touch foil gauge 2, thereby the utility model is contactless pressure device for measuring force.
(4) description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
(5) embodiment
With reference to Fig. 1, in the present embodiment, back of the body bow 1 is the spring steel of a tortuous bow shape, have the high resistance deformation intensity, the two ends of back of the body bow 1 are back-up blocks 4, are used for being placed on stressed test specimen upper support back of the body bow formula pressure gauge, the centre in back of the body bow 1 outside is force block 3, bend 1 outside for application of force test specimen from the back of the body force block 3 is exerted pressure, foil gauge 2 closely sticks on the inboard of back of the body bow 1, carries on the back the dependent variable of bow 1 because being stressed and producing for measuring.
Principle of work: as shown in Figure 1, back of the body bow 1 two end supports piece 4 is placed on the stressed test specimen, back of the body bow 1 is the spring steel of a tortuous bow shape, has high-intensity non-deformability, when being exerted pressure from the middle force block 3 in back of the body bow 1 lateral by measuring pressure, back of the body bow 1 is under pressure and does the time spent and only can produce small distortion, guarantee that stressed test specimen can not touch the foil gauge 2 that sticks on back of the body bow 1 inboard, application of force test specimen can not touch foil gauge 2 yet simultaneously, guaranteed the accuracy that foil gauge 2 is measured, back of the body bow 1 is because the microdeformation amount that pressurized produces changes the dependent variable of foil gauge 2 fully into, and the dependent variable of monitor strain sheet 2 can Measurement accuracy application of force test specimen acts on the pressure on the stressed test specimen.
Claims (2)
1. back of the body bow formula pressure gauge, it contains foil gauge, back-up block, force block, it is characterized in that: also contain back of the body bow, back of the body bow (1) is the spring steel of a tortuous bow shape, the two ends of back of the body bow (1) are back-up block (4), the centre in back of the body bow (1) outside is force block (3), and foil gauge (2) closely sticks on the inboard of back of the body bow (1).
2. the back of the body according to claim 1 bends the formula pressure gauge, it is characterized in that: described back of the body bow (1) profile is the tortuous bow shape.
