Background technology
Tachometer is in the steel pipe's production process, determines an important device of steel pipe length.Mostly the tachometer of Shi Yonging was single roller tachometer in the past, steel pipe in the transmitting moving process with the roller friction of testing the speed, can measure the length of steel pipe.But, in the steel pipe's production process, be subjected to influence of various factors such as machine operation, steel pipe glacing flatness, steel pipe appearance fineness, the steel pipe of high-speed transfer has jumping phenomena unavoidably, because the roller that tests the speed is single roller, steel pipe is not restricted up and down, jumping phenomena can make steel pipe moment and the roller that tests the speed disengage, and forming small leakage changes, thereby influences certainty of measurement, cause the fished pipe error in length bigger, in the actual use of steel pipe, cause the wasting of resources.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of two roller tachometers of avoiding leak changeing, effectively improving certainty of measurement, the minimizing wasting of resources are provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of pair of roller tachometer, it is characterized in that: by frame, upper slide, lower skateboard, roller tests the speed, the auxiliary roller that tests the speed, cylinder, encoder, spring mechanism is formed, upper slide, the lower skateboard branch slides up and down and is installed on central rack, the spring mechanism lower end is installed in frame lower, the spring mechanism upper end installs mutually with the lower skateboard bottom surface, test the speed roller and encoder is coaxially installed on the place ahead, lower skateboard bottom surface and rear respectively, the auxiliary roller that tests the speed is installed on upper slide the place ahead and is positioned at the roller top of testing the speed, roller tests the speed, auxiliary testing the speed forms steel tube pathway between the roller, cylinder bottom is installed in the upper slide end face, and cylinder head installs mutually with the lower skateboard end face.
And described frame is made up of last gusset piece, second line of a couplet fishplate bar, sliding thick stick column, and last gusset piece, second line of a couplet fishplate bar are installed in sliding thick stick column top and bottom respectively.
And described sliding thick stick column is two.
And, the described gusset piece of going up, its central authorities are shaped on cylinder mounting holes.
And described spring mechanism is two groups, and correspondence is installed on the two sliding thick stick columns respectively, two groups of spring mechanisms become by spring base, compression spring set, spring base is installed in sliding thick stick column bottom, and compression spring bottom is installed on the spring base, and the top installs mutually with the lower skateboard bottom surface.
Advantage of the present utility model and good effect are:
1. this pair roller tachometer is provided with the auxiliary roller that tests the speed, and phenomenon is changeed in the leakage that can effectively avoid single roller tachometer to exist, the rate accuracy height, and error reduces by 50%.
2. this pair roller tachometer scientific structure design is reasonable, and have the rate accuracy height, can avoid advantages such as the wasting of resources, be a kind of two roller tachometers that have than high innovation character.
Description of drawings
Fig. 1 is the utility model structural representation (not containing encoder).
Description of reference numerals:
The auxiliary roller that tests the speed of the last gusset piece of 1-, 2-cylinder, 3-cylinder mounting holes, 4-, 5-test the speed roller, the sliding thick stick column of 6-, 7-upper slide, 8-lower skateboard, 9-compression spring, 10-spring base, 11-second line of a couplet fishplate bar.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of pair of roller tachometer is made up of frame, upper slide 7, lower skateboard 8, the roller 5 that tests the speed, the auxiliary roller 4 that tests the speed, cylinder 2, encoder, spring mechanism.Frame is made up of last gusset piece 1, second line of a couplet fishplate bar 11, sliding thick stick column 6, and cunning thick stick column is two, and the two ends of last gusset piece, second line of a couplet fishplate bar are installed in two sliding thick stick column top and bottom respectively, and last gusset piece central authorities are shaped on cylinder mounting holes 3.Upper slide, lower skateboard two ends branch slide up and down the middle part that is installed on two sliding thick stick columns of frame; Spring mechanism is two groups, forms by spring base 10, compression spring 9, and two groups of spring mechanisms are the bottom that the spring base correspondence is installed in the sliding thick stick column of frame, and compression spring bottom is installed on the spring base, and compression spring top installs mutually with the lower skateboard bottom surface; Test the speed roller and encoder is coaxially installed on the place ahead, lower skateboard bottom surface and rear respectively, and the auxiliary roller that tests the speed is installed on upper slide the place ahead and is positioned at the roller top of testing the speed, and the roller that tests the speed, auxiliary testing the speed form steel tube pathway between the roller; Cylinder is positioned at the cylinder mounting holes of gusset piece and is inverted installation, and cylinder bottom is installed in the upper slide end face, and cylinder head installs mutually with the lower skateboard end face.
The operation principle of this pair of roller tachometer is:
On pipe production line, the two roller tachometers of the utility model are installed on fly to saw relevant position, the place ahead on the steel pipe transmitting device, when producing steel pipe, steel pipe is carried operation by the steel pipe transmitting device, steel pipe is by this pair roller tachometer test the speed roller and the auxiliary pore of crossing that tests the speed between the roller, steel pipe table body and with test the speed roller and assist the roller that tests the speed to contact closely, like this, delivered length and the control that can measure steel pipe by the roller that tests the speed, encoder fly the sawing steel pipe, make fished pipe reach the length of demand; When in the steel pipe's production process, be subjected to influence of various factors such as machine operation, steel pipe glacing flatness, steel pipe appearance fineness, when the steel pipe of high-speed transfer produces jumping phenomena, because this pair roller tachometer is provided with test the speed roller and the auxiliary roller that tests the speed, the steel pipe bob is restricted, and beats steel pipe and the roller that tests the speed are disengaged, change thereby avoid forming leaking, guarantee certainty of measurement, the steel pipe trueness error by original ± 4 bring up to ± 2, also avoided in the actual use of steel pipe, causing the wasting of resources; Beat after the elimination, under the effect of cylinder, test the speed roller and the auxiliary roller that tests the speed will return to original state.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
