Abstract: A spirit level is a measuring tool, mainly used to measure whether it is level or not. It is used for comparison in detecting and adjusting the position and inclination angle of machine tools, instrument guide rails, instrument bases and other mechanical equipment, as well as during construction site decoration. many. There are many different types of levels. According to the principle, they can be divided into mechanical levels and electronic levels. According to the structure, they can be divided into adjustable levels and non-adjustable levels. You can choose according to your needs. Let’s introduce to you how to make a spirit level. Let’s learn about it together. 1. What is the function of a spirit level?

A spirit level, as the name suggests, is a ruler for measuring horizontal position. It is a measuring tool that uses a level bubble to indicate the value and directly displays the angular displacement through the level bubble of the liquid in the level ruler. , thereby measuring the relative horizontal position, vertical position, tilt position deviation and other information of the measured surface. The main practical applications of spirit levels are:

1. Detecting and adjusting the horizontal position of machine tools, instrument guide rails, instrument bases and other mechanical equipment.

2. Measure the inclination angle relative to the horizontal plane, such as the straightness and flatness of machine tools, instrument guide rails, rulers, flat plates, etc.

3. Measure the verticality and parallelism of the two planes relative to each other to help with building installation.

2. What are the types of spirit levels?

There are many types of spirit levels, which can be divided into different types according to different classification standards:

1. Principle points

(1) Mechanical level: including strip level (a rectangular level measuring instrument with a base measurement surface and a level bubble fixed or adjustable relative to the base measurement surface) ), frame level (a frame level measuring instrument with a base measuring surface and two vertical measuring surfaces, and the level bubble is fixed or can be adjusted relative to the base measuring surface) and magnetic level (a base measuring instrument The measuring surface and one side of the pedestal are magnetized and can be used for adsorption measurement of the Z-axis of machine tools. There is a magnetic switch)

(2) Electronic level: An electronic level with a display light instead of a water bubble. Observe the color of the indicator light to intuitively see whether it is level; there are also more intuitive digital spirit levels that can directly display numbers, but these are not very durable and are therefore relatively rare.

2. According to structure, it is mainly divided into two types: adjustable level and non-adjustable level.

3. How to make a spirit level

1. Place the cut birch wood on the machine to dig out several holes. Level bubbles containing bubbles and bubbles will be placed in the holes. As a handle.

2. Make burrs on the edges of the wooden strips, and make slots on the edges to fit the copper edging. Flatten the rolled and bent copper strips, fold them into shape, and let the copper edging fit into the horizontal ruler. Insert it into the groove of the wooden strip so that the edge of the wooden strip is protected.

3. Melt the plastic on the other side and injection mold it into an arc-shaped vial (level bubble). The injection-molded vial only needs to be sealed at one end and left open at the other end.

4. The vials are sent to the mechanical claw through the vibrating plate feeder. The mechanical claw holds each vial and rotates it with the opening upward, and injects the yellow mixed liquid (composition: ethylene glycol) into the vial. alcohol + alcohol + water + glycerin), the same amount of liquid is poured into each vial, leaving only the space needed to form bubbles.

5. The mechanical claw puts a plastic cap on the vial, and the plastic cap is welded to the vial through an ultrasonic welding machine to seal the liquid inside the vial.

6. The horizontal bubble with bubbles will be photographed by the camera, and the computer will automatically detect the size and position of the bubble to determine whether it is qualified.

7. Roll the vial on the machine and heat transfer the two indicator lines on the vial. At this time, the vials need to be inspected again, because the deviation of the bubble position will directly affect the accuracy of the level. The vials that pass the inspection will enter the solid welding system, and the molten plastic will be injected into the gap to form the base of the horizontal bubble.

8. Install the horizontal bubbles with a base into the openings of the wooden strips and fix them with glue. Each horizontal bubble must be placed completely horizontally. During the installation process, you need to use a magnified image to ensure accuracy.

9. An acrylic frame should be installed on the outside of the level bubble to protect the level bubble. Rubber caps should be installed with screws on both ends, and trademarks should be printed on the wooden strips. The entire level ruler is ready. alright.

10. Various inspections, such as flatness, accuracy, zero error, etc.
