The objective of the invention is to be achieved through the following technical solutions:
A kind of sawing machine with automatic gauging control function, comprise saw bench, the sawing machine sway brace, photoelectric encoder, the sawing machine cradle, guiding ruler and control circuit, measured workpiece is installed on the roller of sawing machine cradle, its front end passes the sawing machine sway brace and is placed on the worktable, front end at measured workpiece is installed guiding ruler, it is characterized in that: the workpiece of worktable radially side be fixed with a scrambler support, front end cantilever at this scrambler support is fixed with a photoelectric encoder and a roller, photoelectric encoder places the outer rim top of measured workpiece with the coaxial installation of roller, roller.
And, described control circuit is made of photoelectric encoder, grating table, reset button and 36 volts of control power supplys, AC power, the terminal of grating table (1), (2) connect AC power, the terminal of grating table (6), (7) connect 36 volts of control power supplys, on the loop of 36 volts of control power supplys, a contactor is installed, the terminal of grating table (11), (12) connect reset switch, the terminal of grating table (9), (10) are as the input terminal of scrambler, and the terminal of grating table (13), (15) connect photoelectric encoder as the lead-out terminal of scrambler.
And the model that described photoelectric encoder is selected for use is ZF6A-15W-1200BZ-C05CL, and the model that the grating table is selected for use is HB96, and the model that reset switch T selects for use is ZB2-BE101C.
Advantage of the present invention and beneficial effect are:
1, this sawing machine adopts the photoelectric encoder detection to be controlled by counter, and guiding ruler is assisted, and can improve the sizing accuracy of sawing machine thus greatly, enhances productivity the rate of reducing the number of rejects and seconds.
2, this sawing machine adopts roller that workpiece is carried out the radially outer edge contact, and roller drives the photoelectric encoder rotation, and one-piece construction is simple, and design science is reasonable.Through measuring and calculating, do not transform last name operative employee and operate three bench saw beds, owing to adopt automatic gauging, a present behaviour does manual work and can operate four bench saw beds, and production efficiency improves 25%, and existing rejection rate has only 1.5%.

Embodiment
The invention will be further described below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
A kind of sawing machine with automatic gauging control function, constitute by saw bench 5, sawing machine sway brace 2, photoelectric encoder 3, sawing machine cradle 7, guiding ruler 1 and control circuit, measured workpiece 6 is installed on the roller 8 of sawing machine cradle, its front end passes the sawing machine sway brace and is placed on the worktable, at the front end of measured workpiece guiding ruler is installed.
Innovative point of the present invention is:
1, the workpiece of worktable radially side be fixed with a scrambler support 4, front end cantilever at this scrambler support is fixed with a photoelectric encoder and a roller 9, photoelectric encoder and the coaxial installation of roller, be installed on the cantilever of scrambler support, roller places the outer rim top of measured workpiece, i.e. the cylinder of measured workpiece upper end.
The present invention adopts the simplest photoelectric encoder to detect and is controlled by counter.Because the accuracy requirement of processing work is not high, can not adopt high-precision control system or PLC to control like this, can realize in the processing technology claimed range yet.Among the present invention, components and parts are selected the photoelectric encoder model ZF6A-15W-1200BZ-C05L of the smart machine of Wuxi Ke Ruite company limited for use, the counter model is six intelligent digital display counters of HB96G, additional two pushbutton switches just are connected with former panel box can realize accurate positioning function, mechanical part has increased photoelectric encoder metal support and a roller, roller contacts with workpiece, and guiding ruler is done auxiliary, realizes the automatic gauging function.
2, control circuit of the present invention is made of photoelectric encoder, grating table, reset button T and 36 volts of control power supplys, AC power, the terminal 1,2 of grating table connects AC power, the terminal 6,6 of grating table connects 36 volts of control power supplys, on the loop of 36 volts of control power supplys, a contactor KM is installed, the terminal 11,12 of grating table connects reset switch T, terminal 9,10 input terminals as scrambler of grating table, the terminal 13,15 of grating table connects photoelectric encoder as lead-out terminal SLGA, the SLGB of scrambler.
