Abstract
The utility model discloses portable survey hardness hand hammers, including handle, one end of the handle is equipped with tup, the head of the tup is machined with installation cavity, the installation inside cavity, which is inlayed, is equipped with hammering head, the afterbody of the hammering head is provided with hammering sensor, and the hammering sensor is connected by transmission line with detection circuit.This hand hammer is easy to carry, and can detect variously-shaped testee not of uniform size.
Description
Technical field
The utility model belongs to hardness measurements field, more particularly to a kind of portable survey hardness hand hammer.
Background technology
Traditional measurement hardness equipment is mostly mesa structure hardometer, is to cause testee using the identical pressure of size
It deforming upon, the hardness of object is then judged according to deformation size, the big pattern heaviness of volume is inconvenient to carry, and for big
The object of type can not be detected；Rockwell apparatus is convenient for carrying, but is measured in fact using fashion of extrusion, the tested object back of the body
Face needs /V thus can only detect thin miniature workpiece；In formula hardometer using collision theory, acceleration is equipped in impact hammer
Sensor, according to the acceleration detection object hardness that rebounds is hit, impact hammer does the movement of falling object when working, can only detect water
Flat object, it is impossible to detect the abnormal object of shape.
Utility model content
The utility model provides portable survey hardness hand hammer, this hand hammer is easy to carry, and can detect variously-shaped
Testee not of uniform size.
In order to solve the above-mentioned technical problem, the utility model proposes following technical schemes：Portable survey hardness hand hammer, including
Handle, one end of the handle are equipped with tup, and the head of the tup is machined with installation cavity, the installation inside cavity edge
Embedding to be equipped with hammering head, the afterbody of the hammering head is provided with hammering sensor, the hammering sensor by transmission line with
Detection circuit is connected.
The detection circuit includes data storage, display, velocity sensor, signal processor and power module structure
Into.
The front end of the hammering sensor and the afterbody abutting contact of impact head.
The hammering head is made of diamond, and front end is tapering point, and tail end is cylindrical structure.
The utility model has the advantages that：
1st, by above-mentioned hardness hand hammer, in use, when hand hammer impacts testee, when striking speed is identical
When, its dynamics that rebounds of different hardness testee is different, by the various of hand hammer speed, shock rebound dynamics and detection object hardness
Analogue data is stored in the data storage in detection circuit；During detection when brandishing hand hammer impact measured object, the speed on tup
Degree sensor can collect the speed of hammer body, and impact head can generate rebound power when hitting testee is knocked sensor acquisition
To signal and pass through transmission line and be delivered to detection circuit, detection circuit can be analyzed by speed and rebound force value
The hardness level of testee.
2nd, the hardness hand hammer of the utility model is convenient for manufacture, and when detection only brandishes hand hammer impact testee, both
Can be easy to carry, and variously-shaped and not of uniform size volume testee can be detected.
3rd, it ensure that its service life by using hammering head made of diamond.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the overall structure diagram of the utility model.
In figure：Tup 1, handle 2；
Detection circuit 1.1, transmission line 1.2 hammer sensor 1.3, hammer first 1.4, installation cavity 1.5.
Specific embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, portable survey hardness hand hammer, including handle 2, one end of the handle 2 is equipped with tup 1, described
The head of tup 1 is machined with installation cavity 1.5, is inlayed inside the installation cavity 1.5 and is equipped with hammering first 1.4, the hammering
First 1.4 afterbody is provided with hammering sensor 1.3, and the hammering sensor 1.3 passes through transmission line 1.2 and detection circuit 1.1
It is connected.
Further, the detection circuit 1.1 include data storage, display, velocity sensor, signal processor and
Power module is formed.
Further, the front end of the hammering sensor 1.3 and the afterbody abutting contact of impact head 1.4.
Further, the hammering first 1.4 is made of diamond, and front end is tapering point, and tail end is cylinder
Structure.
The course of work operation principle of the utility model：
During detection object hardness, handle of holding with a firm grip makes impact head one end to testee, brandishing hand hammer impact testee,
Velocity sensor during it in detection circuit collects hand hammer striking speed, and impact microphone, which collects, hits bounce simultaneously
Detection circuit is transported to by transmission line, shows corresponding hardness number in display using signal processor sunykatuib analysis
Go out.
By above-mentioned description, those skilled in the art completely can be without departing from this item utility model technological thought
In the range of, various changes and amendments are carried out all within the scope of protection of the utility model.The utility model is not use up
Matters belong to the common knowledge of those skilled in the art.
