Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, and more specifically relates to an anti-blocking water tank for numerical control machine tools. Background Art

[0002] The cooling water tank is one of the important components of CNC machine tools. It can realize the recycling of coolant and cool the parts, tools and corresponding components being processed to ensure the stability of CNC processing. Specifically, the coolant after spraying flows naturally and is recovered into the interior of the cooling water tank. The coolant added or recovered inside the cooling water tank will be pumped again for spraying cooling.

[0003] When the existing cooling water tank is in use, its internal filter component has no indicator structure. The filter component will gradually become clogged as the use time increases. Since there is no indicator mechanism, the degree of clogging of the filter component can only be judged by manual experience. Replacing the filter component too early will lead to waste of components, and replacing the cooling component too late will lead to reduced coolant recovery efficiency and poor filtering effect, which is not practical.

[0024] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples.

[0025] As attached Figure 1 To the attached Figure 5 As shown:

[0026] Example 1: The utility model provides a CNC machine tool anti-blocking water tank, including a water tank 1 and a pipe assembly 2. The pipe assembly 2 includes an installation pipe 201, a connecting pipe 202, a filter plate 203, and an indicator rod 204. The installation pipe 201 is detachably fixed to the side of the connecting pipe 202, the filter plate 203 is inserted into the interior of the connecting pipe 202, and a filter element is provided inside the filter plate 203. The indicator rod 204 is radially inserted into the top of the installation pipe 201.

[0027] There are two groups of pipe assemblies 2, one of which is arranged at the top of the side of the water tank 1, and the connecting pipes 202 of this group of pipe assemblies 2 are fixedly connected to the water tank 1, and the other group of pipe assemblies 2 is arranged at the bottom of the other side of the water tank 1, and the installation and removal pipes 201 of this group of pipe assemblies 2 are fixedly connected to the water tank 1.

[0028] In the embodiment of the present disclosure, the installation and removal pipe 201 of the pipe assembly 2 arranged at the top is connected to the circulating water inlet pipe, and the connecting pipe 202 of the pipe assembly 2 arranged at the bottom is connected to the circulating water outlet pipe. During use, the filter plates 203 of the two sets of pipe assemblies 2 are both arranged in the direction facing the flow of liquid, so that the liquid can be stably filtered by the filter element inside the filter plate 203 when flowing through the filter plate 203, avoiding impurities and iron filings from flowing into the water tank 1 during the circulation of the coolant, causing damage to the pump body, and stable use.

[0029] In the embodiment of the present disclosure, a force-applying spring 2031 is provided on the side of the filter disc 203, and the two ends of the force-applying spring 2031 respectively press against the side of the filter disc 203 and the inside of the connecting pipe 202. During use, the pipe assembly 2 has the function of indicating the degree of blockage of the filter disc 203. Due to the presence of the filter element, there is a certain resistance when the liquid is pumped through the filter disc 203. When the resistance is less than the force applied by the force-applying spring 2031 on the filter disc 203, the force-applying spring 2031 will not be deformed and the filter disc 203 can stably maintain the current use position. A selection magnet 2033 is provided on the top of the filter disc 203, and an indication magnet 2041 is provided at the bottom of the indicator rod 204. There are multiple indication magnets 2041 arranged in a straight line along the axial direction inside the connecting pipe 202, and the indication magnets 2041 are located on the moving path of the selection magnets 2033. The selection magnets 2033 and the indication magnets 2041 are relative to each other at the same level. When the filter disc 203 is in use, the filter disc 203 is in a state of being filled with liquid and the filter element 203 is in a state of being exhausted.

[0030] In the embodiment of the present disclosure, a track block 2032 is provided on the side of the filter disc 203, and a track groove 2021 is provided inside the connecting pipe 202. The track block 2032 is inserted into the inside of the track groove 2021. The track groove 2021 can limit the moving trajectory of the filter disc 203 when the blockage degree changes through the track block 2032, and is stable to use.

[0031] The specific usage and function of this embodiment are as follows:

[0032] In the present invention, the recovered coolant can flow into the interior of the water tank 1 through the top pipe assembly 2, and the coolant inside the water tank 1 can flow out through the bottom pipe assembly 2 and be pumped for use again. The filter discs 203 of the two sets of pipe assemblies 2 are both arranged to face the direction of liquid flow, so that the liquid can be stably filtered by the filter element inside it when flowing through the filter disc 203, avoiding impurities and iron filings from flowing into the interior of the water tank 1 and causing damage to the pump body during the coolant circulation. The pipe assembly 2 has the function of indicating the degree of blockage of the filter disc 203. Due to the presence of the filter element, there is a certain resistance when the liquid is pumped through the filter disc 203. When the resistance is less than the force applied by the force-applying top spring 2031 on the filter disc 203, the force-applying top spring 2031 will not be deformed and the filter disc 203 can stably maintain the current use position, and at this time, the magnetic block 2033 is selected and it is directly above it. Under the same-level repulsion between the indicating magnetic blocks 2041, the indicating magnetic block 2041 directly above the selecting magnetic block 2033 is lifted up, thereby indicating the current use position of the filter disc 203 through the indicating rod 204. As the use time of the filter disc 203 increases, the resistance of the liquid when being pumped through the filter disc 203 will also increase. Therefore, when the resistance is greater than the action of the force-applying top spring 2031, the filter disc 203 will move to one side and compress the force-applying top spring 2031, thereby changing the use position of the selecting magnetic block 2033. After the use position of the selecting magnetic block 2033 is changed, the indicating magnetic block 2041 at its corresponding position will be lifted up, thereby changing the indicating position of the indicating rod 204. By indicating the use position of the filter disc 203, the degree of blockage of the filter element inside the filter disc 203 is indicated, which makes it convenient for the staff to judge whether the filter element inside the filter disc 203 needs to be replaced.

[0033] Example 2: Based on Example 1, a reset spring is provided on the outside of the indicator rod 204, and the two ends of the reset spring are respectively against the inside of the connecting pipe 202 and the bottom of the indicator rod 204. This design allows the indicator rod 204 to be hidden inside the connecting pipe 202 under the action of the reset spring when the selection magnet 2033 at the bottom of the indicator rod 204 is not directly above the selection magnet 2033, and will not hinder or disrupt the indication status of the other indicator rods 204, making it convenient to observe.

[0034] In another embodiment, a recovery pump is installed between the connecting pipe 202 of the top pipe assembly 2 and the water tank 1, thereby improving the recovery efficiency of the coolant.
