Abstract
The utility model discloses a kind of shock machine digitized measurement system, including balance weight impact testing machine, incremental rotary encoder, programmable controller and the text display being sequentially connected, the angular displacement that Charpy impact is swung can be converted into digital pulse signal by the incremental rotary encoder, the programmable controller can transmit the digital pulse signal come to the incremental rotary encoder and count and handle, and calculate energy value and be transferred to the text display and shown.The utility model avoids the error that dial needle formula reading is brought to measurement result, it is achieved thereby that the high-acruracy survey of shock machine impact energy.
Description
Technical field
A kind of shock machine technical field is the utility model is related to, more specifically a kind of shock machine digitlization
Measuring system.
Background technology
Impact tester for simple supported beam suitable for various nonmetallic materials impact flexibility test, be scientific research institution, universities and colleges,
Related factories and miness carry out the common equipment of quality inspection.
Impact tester for simple supported beam be mainly used in rigid plastics (including sheet material, tubing, plastics opposite sex material), enhancing nylon,
The measure of the impact flexibility of the nonmetallic materials such as fiberglass, ceramics, cast stone, electrically insulating material.Its conventional energy instruction device is normal
Shown using mechanical pointer dial.Dial shows three inconvenience：First, reading is inconvenient, apparent value error is big；Second, machine
Tool pointer structure easily loosens, and to be checked frequently after experiment and adjust pointer tension force；Third, experiment will be manually recorded every time, test
Also manually test data input computer is analyzed and processed afterwards, reduce operating efficiency.
Utility model content
The purpose of this utility model is to avoid deficiency of the prior art and provide a kind of convenient reading, high accuracy, height
The shock machine digitized measurement system of efficiency, the utility model are achieved through the following technical solutions：
A kind of shock machine digitized measurement system, including the balance weight impact testing machine, the increment type that are sequentially connected rotate
Encoder, programmable controller and text display, the angular displacement that the incremental rotary encoder can swing Charpy impact
Digital pulse signal is converted into, the programmable controller can transmit the digit pulse come to the incremental rotary encoder to be believed
Number count and handled, calculate energy value and be transferred to the text display and shown.
Wherein, text display is TD200 text displays.
The utility model applies incremental rotary encoder and programmable controller (PLC), turns what encoder provided
Input signal of the axle pulse as PLC high-speed counters, take full advantage of time, angle high-resolution characteristic and the height of encoder
Fast counter it is ageing, avoid the error that dial needle formula reading is brought to measurement result, it is achieved thereby that impact examination
Test the high-acruracy survey of machine impact energy.
Brief description of the drawings
Using accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not formed to of the present utility model
Any restrictions, on the premise of not paying creative work, can also be according to following attached for one of ordinary skill in the art
Figure obtains other accompanying drawings.
Fig. 1：System block diagram of the present utility model.
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and have
The utility model is described in further detail body embodiment, it is necessary to explanation is, in the case where not conflicting, the application's
Feature in embodiment and embodiment can be mutually combined.
As shown in figure 1, a kind of shock machine digitized measurement system described in the utility model, including be sequentially connected
Balance weight impact testing machine, incremental rotary encoder, programmable controller and text display.Incremental rotary encoder is one
Kind is converted to angular displacement the rotating detector of series of digital pulses signal, when pendulum rotating shaft drives encoder code disc rotating shaft
When rotating coaxially, receiver experiences code-disc and rotates caused change, light change then is converted into corresponding Electrical change, and lead to
Cross electronic circuit processing after in the form of high and low level is alternate outputting standard square shape pulsed signal.To improve the steady of measuring system
Qualitative, output signal transmission uses differential mode, effectively eliminates interference, can accurately record the angle of pendulum.PLC technology
Device (PLC) has the functions such as high-speed counting, the standard square pulse letter that PLC high-speed counters export to incremental rotary encoder
Number count, energy value is calculated by relative program, and text display is transferred to by RS232 serial communications, shown simultaneously
On text display.The present embodiment carries out numerical monitor using TD200 text displays.
Many details are elaborated in above description in order to fully understand the utility model, still, this practicality is new
Type can also be different from other modes described here to implement using other, it is thus impossible to be interpreted as protecting the utility model
Protect the limitation of scope.
In a word, although the utility model lists above-mentioned preferred embodiment, although it should be noted that the skill of this area
Art personnel can carry out various change and remodeling, unless such change and remodeling deviate from the scope of the utility model, otherwise
It should be construed as being included in the scope of protection of the utility model.
