[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1-3 As shown, the utility model provides a liquid level gauge for a liquid collecting tank of a CNC machine tool, which is installed on one side of a liquid collecting tank 5 and includes a mounting seat 1, a liquid level gauge cover plate 2 connected to the mounting seat 1, and a liquid level tube 3;

[0033] The liquid level tube 3 is vertically arranged and installed in the liquid level gauge cover plate 2. The lower end of the liquid level tube 3 is connected to the lower part of the liquid collecting tank 5, and the upper end of the liquid level tube 3 is an open structure to communicate with the atmosphere. The liquid level tube 3 is set to a transparent material;

[0034] The liquid level gauge cover 2 is detachably connected to the mounting base 1 and forms a accommodating cavity for the liquid level tube 3. A groove extending in the length direction is provided on the liquid level gauge cover 2 and is arranged opposite to the liquid level tube 3. The groove forms an observation window corresponding to the liquid level tube 3, which is convenient for the operator to observe the liquid level of the chip liquid in the liquid level tube 3.

[0035] On the basis of the above-mentioned embodiment, the mounting seat 1 is welded and fixed to the liquid collecting tank 5, and the mounting seat 1 is configured as a U-shaped sheet metal bending part;

[0036] The liquid level gauge cover plate 2 is configured as a sheet metal part, which is fastened to the mounting base 1 by bolts. The mounting base 1 and the liquid level gauge cover plate 2 are both made of stainless steel to avoid bumps.

[0037] Based on the above embodiments, Figure 4-5 As shown, the level gauge cover plate 2 includes a panel 21 and a bottom plate 22, a plurality of first waist-shaped holes are provided on the bottom plate 22, threaded holes matching the first waist-shaped holes are provided on the mounting seat 1, and a through hole for bolts to pass through is provided on the panel 21 and is coaxial with the first waist-shaped holes;

[0038] During the installation process, the operator uses a screwdriver to pass the bolt through the panel 21 and locks it on the mounting base 1 through the first waist-shaped hole of the base plate 22. A through hole for the bolt to pass through is opened on the panel 21, which can shorten the thread length of the bolt. Ordinary bolts can meet the use requirements without customization. The first waist-shaped hole opened on the base plate 22 matches the threaded hole of the mounting base, reducing the processing difficulty and improving the installation accuracy.

[0039] Based on the above embodiments, Figure 6 As shown, the lower end of the liquid level tube 3 is connected to the lower part of the liquid collecting tank 5 through a pipe joint 4. The pipe joint 4 adopts a PL external thread right-angle quick-connect joint. The pipe joint 4 is threadedly connected to the liquid collecting tank 5. The liquid level tube 3 is plugged into the pipe joint 4, making the disassembly and installation between the two more convenient and quick. The liquid level tube 3 is made of PU material.

[0040] When in use, first connect the liquid level tube 3 with the liquid collecting tank 5 through the pipe joint 4. The upper end of the liquid level tube 3 is an open structure, which is connected to the atmosphere, so that the liquid in the liquid collecting tank 5 can enter the liquid level tube 3 through the pipe joint 4. Since the liquid level tube 3 is connected from top to bottom, the height of the liquid level in the liquid level tube 3 is equal to the height of the liquid level in the liquid collecting tank 5. The height of the liquid level in the liquid level tube 3 can be observed through the groove opened on the liquid level gauge cover plate 2, and the height of the liquid level in the liquid collecting tank 5 can be obtained.

[0041] On the basis of the above embodiment, the upper end of the liquid level tube 3 protrudes from the liquid level gauge cover plate 2, and the liquid level gauge cover plate 2 also includes an upper end plate 23 and a lower end plate 24. A second waist-shaped hole for the liquid level tube 3 to pass through is opened on the upper end plate 23 and the lower end plate 24 to assist in the vertical positioning of the liquid level tube 3.

[0042] Based on the above embodiments, Figure 7 As shown, the groove is opened on the panel 21, facing the operator, and is easy to observe; a liquid level indicator 6 is also provided on the panel 21, and the liquid level indicator 6 is carved on the panel 21 and arranged along the length direction of one side of the groove, so as to measure the liquid level.

[0043] On the basis of the above embodiment, the liquid level indicator 6 is configured as a strip plate, which is arranged on the groove to indicate the highest dangerous liquid level of the liquid level tube 3, reminding the operator to pay attention, which is intuitive and clear.
