Technical Field

The invention relates to liquid level monitoring and detection, in particular to liquid level monitoring and detection of a water tank for a machine tool and alarm of liquid level limit.

Background

In production and life, various liquid level control devices are various, and different fields have liquid level control devices with different structures and forms. The machine tool water tank liquid level control in the machining usually uses a mechanical liquid level alarm switch, and has the advantages that on one hand, a signal can be sent according to the liquid level, and then the machine tool is automatically controlled; on the other hand producer and equipment maintenance personnel can be directly perceived convenient according to the height condition of liquid level alarm device's pointer frame judgement water tank liquid level, and then judge whether to carry out the moisturizing to the water tank, and early warning in advance can effectively reduce the loss of stopping production that equipment scram caused.

In the actual production process, the conventional liquid level alarm switch has the disadvantages of complex structure, more material consumption, large occupied area, complex manufacturing process and high cost. The main structure of the alarm switch is a metal plate or a pipe, so that a plurality of procedures such as bending, welding and the like are required, on one hand, the procedures can cause dimension errors and deformation, and in practical application, the alarm switch can not be smoothly locked and fails; on the other hand, the floating ball has no protective measures, and the floating ball can be jacked by foam under the condition of more liquid foam, so that the condition of false alarm is caused.

Disclosure of Invention

In order to solve the technical problems, the invention provides a liquid level monitoring device and an assembly method thereof. The built-in multiple guide mechanism can ensure that the guide rod smoothly moves up and down, avoid the occurrence of clamping stagnation and deviation, and greatly improve the use reliability.

The technical scheme adopted by the invention for solving the technical problems is as follows: a liquid level monitoring device comprises a main body, an indicating piece, a cylindrical guide rod and a floater, wherein the main body comprises a section bar upright post, a bottom plate and a guide piece; the bottom plate is fixed on the bottom surface of the profile upright post; the guide piece is fixed on the bottom plate close to the section bar upright post and is fixed on the same surface with the section bar upright post; the cylindrical guide rod penetrates through the bottom plate and the guide piece and is arranged in parallel with the section bar upright post; the pointer frame is fixed at one end, close to the section bar stand column, of the cylindrical guide rod, and the floater is fixed at the other end of the cylindrical guide rod.

Furthermore, the indicating part still includes indicating part, scale bar, the scale bar sets up section bar stand length direction just is close to one side of pointer frame.

Through the pointer frame in the position of scale strip, the liquid level condition in the liquid tank just can be observed clearly to operating personnel, convenient and fast.

Furthermore, the section bar upright post is made of square aluminum alloy section bars.

By adopting the aluminum alloy section, on one hand, the peripheral structure can be used as a mounting base, and the processes of punching, bending, welding and the like are not needed, so that the manufacturing is simple and the cost is lower. On the other hand, the appearance is attractive, the length is cut according to the size, and the size and the precision are easy to guarantee.

Further, the device also comprises a detection assembly, wherein the detection assembly comprises at least one detection switch and at least one detection bracket; each detection bracket is arranged on the section bar upright post; the detection switch is installed on the detection support, and the detection surface is matched with the operation direction of the pointer frame.

Through the position that detects the pointer frame of detection switch intelligence, also can directly know the condition of present liquid level, do not need the manual observation.

Further, still include the alarm, the alarm sets up on the section bar stand. Through the installation alarm, can send out alarm sound when detection switch detects the pointer frame, the suggestion operating personnel present liquid tank liquid level appears unusually, needs handle.

Furthermore, a guide post is arranged on the pointer frame; one side of the section bar upright column in the length direction is provided with a guide groove matched with the guide column; the guide post moves up and down along the guide groove.

Therefore, the cylindrical guide rod has guide of the guide piece and guide of the guide groove during operation, and double guide is realized, so that the operation is smoother.

Further, the float is a hollow sphere or cylinder.

The floater can be spherical or cylindrical according to actual needs and is in threaded connection with the guide rod. The material can also be made of plastic or stainless steel.

Still include the guard shield, the guard shield is installed the bottom plate is kept away from the one side of stand.

Through set up the guard shield on liquid level detection device, the guard shield protects the floater all around, avoids the foam to get into the condition emergence that jack-up floater caused the wrong report to police.

According to the technical scheme, the liquid level monitoring device has the beneficial effects that at least, the aluminum alloy section is used as the upright post of the liquid level monitoring device, the corresponding length can be directly cut, and then the detection support and other components are installed according to the self structure, so that the liquid level monitoring device is convenient and quick to use and low in cost. And secondly, the automation of the liquid level monitoring device can be improved and the labor force is liberated through the position of the pointer frame on the scale bar and the application of the detection switch and the alarm. And the double guide structure of the cylindrical guide rod ensures that the problem of clamping stagnation or deviation can not occur during operation.
