Detailed Description
The invention is further described with reference to the following figures and examples.
Referring to fig. 1, a level provided with an indicator tube heating mechanism comprises a base 5, an indicator tube heating structure 6, a temperature sensor 51 and a control unit (not shown).
An indicator tube 53 is provided in the base 5. The indicator tube 53 is a light-transmitting tube such as glass, acrylic, or the like. An observation window 54 is provided on the upper surface of the base 5 at a position directly above the indicator pipe 53. The indicator tube 53 is provided with a bubble 55 and filled with liquid. The temperature sensor 51 is located within the indicator tube 53.
The indicator tube heating structure 6 includes a heat conductive iron case 61, a metal scraping fork 62, and a driving mechanism 63. The outer surface of the iron shell 61 is a cylindrical surface. The iron shell 61 is wrapped outside the indicator tube 53 in a sleeved manner. The iron case 61 is bonded to the indicator tube 53 by a thermally conductive adhesive. The iron case 61 is provided with an escape groove 611 for observing the position of the air bubbles. The metal scraping fork 62 is sleeved outside the iron shell 61. The metal scraping fork 62 abuts against the iron shell 61. The metal blade fork 62 includes a root 621 and two arc-shaped blades 622. The root 621 and the inner peripheral surfaces of the two arc-shaped blades 622 are located on the same cylindrical surface. The root 621 and the two arc-shaped blades 622 are integrally formed together. The arc blade 622 is elastically connected to the root 621. The arc-shaped blade 622 is provided with a blade pressing structure 64. The blade pressing structure 64 includes a tip wire 641, a driving block 642, and a slide bar 643. The jack screw 641 is screwed to the base 5. One end of the tip 641 is exposed to the outside of the base 5. The other end of the tip 641 abuts against one end of the driving block 642. A drive block 642 is slidably connected within the base. The other end of the driving block 642 is sleeved on the sliding rod 643. The slide bar 643 extends in the extending direction of the indicator tube. A sliding rod 643 is disposed through the arcuate blade 622. The ends of the sliding rod 643 are fixed with the base.
The driving mechanism 63 includes a screw 631 screwed to the metal scraping fork and a motor 9 (not shown) for driving the screw to rotate. The lead screw 631 is parallel to the slide bar 643. The screw rod 631 is connected with a thread sleeve 633 through screw threads. A threaded sleeve 633 extends through root 621. The thread sleeve 633 is fixedly connected with the root 621.
The method of warming a level of the present invention, in a first step, supports a base on an object being measured. The temperature of the indicator tube 53 is detected by the temperature sensor 51 during the measurement; secondly, if the temperature sensor detects that the temperature of the indicating pipe is lower than a set value, the control unit drives the driving mechanism 63 to drive the metal scraping fork 62 to do reciprocating linear motion along the length direction of the indicating pipe; and thirdly, when the metal scraping fork performs resetting linear motion on the iron shell, the metal scraping fork generates scraping together with the iron shell to generate heat, and the heat generated by friction is transferred to the indicating tube to heat the indicating tube so as to reduce errors caused by diameter changes of the indicating tube due to low temperature.
The driving process of the driving mechanism 63 is that the motor drives the screw rod to rotate forward and backward, and the screw rod drives the metal scraping fork 62 to do reciprocating linear motion through the thread sleeve 633.
If the contact force of the arc-shaped blade 622 and the iron shell is too small or a gap is generated, and heat cannot be effectively scraped, the top wire 641 is rotated, the top wire 641 drives the driving block 642 to press the sliding rod 643 to close towards the indicating tube, and the sliding rod 643 drives the arc-shaped blade 622 to push against the indicating tube.
