Description
Technical field
This utility model belongs to locating cylinder workpiece areas.
Background technology
Power transmission shaft is one of most important part during power is transmitted.As technique is limited, as the length of power transmission shaft increases,
Then it is more difficult to ensure its axiality, therefore, cannot generally process especially long power transmission shaft.And in real work, Jing will often make
Long bearing is used, is then interconnected by short axle is held, replace long power transmission shaft.
The patent of Patent No. CN201520831186.5, discloses a kind of automatic centering structure, the automatic centering knot
Structure includes centering transaxle, positioned at the left centering rod and right centering rod of centering transaxle both sides, the right-hand member of the left centering rod is solid
Surely left tooth bar is provided with, the left end of right centering rod is fixed with right tooth bar, and centering transaxle is located between left tooth bar and right tooth bar, bag
Shell, rotating shaft, bearing and gear are included, its simple structure, by the cooperation of wheel and rack, when the centering rod of side is moved,
The centering rod of opposite side also can do contrary motion therewith.
Relative to artificial centering, the accuracy of alignment of the centering body improves, but which is mainly by machinery
Measuring, precision is high not enough, it is impossible to meet the requirement of some high accuracy installs for the mode of formula.
Utility model content
The purpose of this utility model is to provide a kind of centralising device of high precision.
In order to achieve the above object, base case of the present utility model provides a kind of power transmission shaft and installs centralising device, including
Positioning wedged block, RF transmitter, infrared receiver and Magnet, the positioning wedged block are U-shaped, and the Magnet is fixed on positioning
Two free ends of fixture block, are provided with cavity in the positioning wedged block, be provided with ink, be provided with printing opacity in the cavity in the cavity
Hole, is provided with transmissive mirror in the loophole, during the positioning wedged block horizontal positioned, ink is located just at the bottom of transmissive mirror, institute
RF transmitter is stated installed in the side of positioning wedged block, infrared receiver is arranged on the opposite side of positioning wedged block, described red
Outside line emitter and infrared receiver are correspondingly arranged with transmissive mirror.
The principle of this base case is：By on power transmission shaft positioning wedged block installed therein, and Magnet is inhaled exist
Fixation on power transmission shaft.Then, RF transmitter is arranged on the side of positioning wedged block, infrared receiver is arranged on
On another power transmission shaft.Start RF transmitter, if the infrared ray of RF transmitter transmitting can enter project from transmissive mirror,
Then illustrate that two transmission shaft assignments are accurate.As long as there is one of infrared ray to be stopped by ink, then explanation is driven shaft assignment not
Accurately, also need to be adjusted.
The beneficial effect of this base case is：Compared with traditional power transmission shaft centralising device, this programme by Magnet come
Stationary positioned fixture block, is fixed conveniently.In addition, judging whether that by infrared ray centering accurately, greatly improves the essence of centering
Exactness.
Scheme two：Based on this, scheme is preferred, and the Magnet is permanent magnet.Relative to common Magnet, permanent magnet is difficult
Demagnetization, long service life.
Scheme three：Based on this, scheme is preferred, and the positioning wedged block is aluminium alloy positioning wedged block.It is fixed made by aluminium alloy
Position fixture block is lightweight, therefore, it is difficult to come off from power transmission shaft.Simultaneously as ink is provided with positioning wedged block, aluminium alloy is difficult life
Rust, long service life.
Scheme four：This is preferred for scheme two, is provided with rubber blanket on the inside of the Magnet.Rubber blanket has good buffering
Performance, effectively avoids damaging power transmission shaft.
Scheme five：Based on this, scheme is preferred, and the ink is black ink.It is relative to the ink of other colors, black
The occlusion effect of chromatic ink is more preferable, it is ensured that measurement result is accurate.
Description of the drawings
Fig. 1 is the sectional view that this utility model embodiment power transmission shaft installs convenience-for-people area in centralising device.
Specific embodiment
This utility model is described in further detail below by specific embodiment：
Reference in Figure of description includes：Positioning wedged block 10, ink 20, transmissive mirror 30, Magnet 40, rubber blanket
50。
Embodiment power transmission shaft installs centralising device substantially as shown in Figure 1：
A kind of power transmission shaft installs centralising device, including positioning wedged block 10, RF transmitter, infrared receiver and Magnet
40.Positioning wedged block 10 is U-shaped, and positioning wedged block 10 is aluminium alloy positioning wedged block 10.Made by aluminium alloy, positioning wedged block 10 is lightweight,
Therefore, it is difficult to come off from power transmission shaft.Simultaneously as being provided with ink 20 in positioning wedged block 10, aluminium alloy is difficult to get rusty, using the longevity
Life length.The quantity of Magnet 40 is two, is separately mounted to two free ends of positioning wedged block 10.
Cavity is provided with positioning wedged block 10, the ink 20 of black in cavity, is provided with.Loophole is provided with cavity, in loophole
Transmissive mirror 30 is provided with, during 10 horizontal positioned of positioning wedged block, ink 20 is located just at the bottom of transmissive mirror 30.RF transmitter is pacified
