Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a water tank for CNC machine tools. Background Technology

[0002] As the core equipment of modern manufacturing, CNC machine tools are directly related to product quality in terms of their machining accuracy and stability. During the machining process, cutting fluid plays a key role in cooling the cutting tool, removing chips, and lubricating the machined surface. The water tank, as the storage, circulation, and filtration unit of cutting fluid, is an indispensable and important component of the CNC machine tool cooling system.

[0003] In practical use, traditional CNC machine tool water tanks are usually equipped with casters for easy movement. However, during machine operation, the vibration generated by the equipment is transmitted to the water tank through the ground, causing slight shaking of the tank body and the liquid surface. In addition, the contact area between the casters and the ground is small. When the machine tool vibrates at high speed, the water tank is prone to displacement, which can lead to the leakage of cutting fluid, affecting the stability of the water tank and indirectly reducing machining accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a water tank for CNC machine tools, which aims to solve the problem in the prior art that "water tanks equipped with casters are prone to displacement due to water tank vibration during operation, resulting in cutting fluid overflow and reducing the stability of the water tank".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water tank for a CNC machine tool, comprising a tank body, a filter frame installed on the top of the tank body, two sets of symmetrically arranged movable feet fixedly connected to the right side of the tank body, a support assembly disposed between the two sets of movable feet, a cleaning assembly disposed inside the filter frame, and the support assembly comprising a fixing block fixedly connected between the two sets of movable feet, a rotating rod rotatably connected to the middle of the fixing block, a positioning plate fixedly connected to the bottom of the rotating rod, and the positioning plate rotatably connected to the inner part of the fixing block. The outer wall of the positioning disk is elastically connected to the fixed block by a torsion spring. The torsion spring is located below the positioning disk on the inner wall of the fixed block. Limiting blocks are fixedly connected to both the front and rear sides of the rotating rod. A sliding groove for the sliding space of the limiting block is opened at the top of the fixed block. Two sets of positioning rods are slidably connected through the bottom of the fixed block. The two sets of positioning rods are respectively located on the front and rear sides of the rotating rod. Two sets of slots are opened on the opposite surfaces of the two sets of positioning rods. The limiting block is engaged with the inner wall of the slot. A support plate is fixedly connected to the bottom of the two sets of positioning rods.

[0006] As a further description of the above technical solution: The card slot is designed to be arc-shaped.

[0007] As a further description of the above technical solution: The groove is designed to be arc-shaped.

[0008] As a further description of the above technical solution: A rotating ring is fixedly connected to the top of the rotating rod.

[0009] As a further description of the above technical solution: A guide block is fixedly connected to the right side of the support plate.

[0010] As a further description of the above technical solution: A rubber pad is fixedly connected to the bottom end of the support plate.

[0011] As a further description of the above technical solution: The cleaning assembly includes a scraper that is slidably connected to the bottom of the filter frame. A support block is fixedly connected to the top of the scraper. A fixing rod is fixedly connected to the inside of the filter frame. The support block passes through and is slidably connected to the outer wall of the fixing rod.

[0012] As a further description of the above technical solution: The top of the support block is hinged with a handle.

[0013] This utility model has the following beneficial effects: 1. In this utility model, rotating the rotating ring drives the rotating rod to rotate, causing the limiting block to move out of the slot. Then, pressing the guide block drives the positioning rod to slide down until the rubber pad at the bottom of the support plate contacts the ground. At this time, the limiting block, together with the torsion spring, limits the positioning rod, so that the support plate and the rubber pad can stably support the water tank, increasing the friction between the water tank and the ground, effectively preventing the water tank from shaking and displacing during operation, ensuring the stability of the cutting fluid circulation, and thus improving the machining accuracy and quality.

[0014] 2. In this utility model, by flipping the handle upwards, the support block slides along the fixed rod, and simultaneously the scraper slides inside the bottom of the filter frame, which can scrape and clean the filter holes at the bottom of the filter frame. It does not require frequent disassembly of the filter frame, and the operation is simple and quick. It can remove iron filings from the holes in time, ensure the smooth filtration of the filter frame, and enable the cutting fluid to be continuously and effectively circulated. It reduces equipment downtime caused by filter blockage, improves production efficiency, and also reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a water tank for a CNC machine tool, comprising a tank body 1, which is the main body of the water tank. A filter frame 4 for filtering iron filings is installed on the top of the tank body 1. Two sets of symmetrically arranged movable feet 41 are fixedly connected to the right side of the tank body 1. Movable feet 41 and support components 2 are provided on both the left and right sides of the tank body 1. The movable feet 41 facilitate the movement of the tank body 1. A support component 2 for increasing the stability of the tank body 1 is provided between the two sets of movable feet 41. A cleaning component 3 for cleaning the filter holes at the bottom of the filter frame 4 is provided inside the filter frame 4. The support component 2 includes a fixing block 210 for providing support. The fixing block 210 is fixedly connected between the two sets of movable feet 41. The middle part of the fixing block 210... A rotating rod 21 is rotatably connected to drive two sets of limiting blocks 23 to rotate. A positioning disk 211 supporting the rotating rod 21 is fixedly connected to the bottom of the rotating rod 21. The positioning disk 211 is rotatably connected inside the fixed block 210. The outer wall of the positioning disk 211 is elastically connected to the fixed block 210 through a torsion spring 29. When the rotating rod 21 rotates, it will drive the two sets of limiting blocks 23 to rotate and move out of the slot 212, thereby releasing the limiting position of the positioning rod 27. At the same time, the rotating rod 21 will compress the torsion spring 29. The elastic force of the torsion spring 29 can make the limiting blocks 23 quickly reset. The torsion spring 29 is located below the positioning disk 211 on the inner wall of the fixed block 210. The fixed block 210 below the positioning disk 211 has a space inside to provide movement for the torsion spring 29.

[0019] Reference Figure 2 - Figure 4 Both the front and rear sides of the rotating rod 21 are fixedly connected to limiting blocks 23 that fit into the inner wall of the slots 212 to limit the positioning rod 27. The top of the fixed block 210 is provided with a sliding groove 25 for the sliding space of the limiting block 23. The bottom end of the fixed block 210 is slidably connected to two sets of positioning rods 27 that provide support and drive the support plate 24 to move. The two sets of positioning rods 27 are respectively set on the front and rear sides of the rotating rod 21. The opposite surfaces of the two sets of positioning rods 27 are respectively provided with two sets of slots 212. The two sets of slots 212 are respectively set to support the box 1 with the support plate 24 and to retract it after the support is released. The limiting block 23 is engaged in the slot 212. The inner wall of the slot 212 is arc-shaped, and the arc shape provides a corresponding limit block 23 to provide a locking space for arc rotation. The slide 25 is arc-shaped, and the arc shape provides a corresponding limit block 23 to move. The top of the rotating rod 21 is fixedly connected to a rotating ring 22 that drives the rotating rod 21 to rotate. The bottom ends of the two sets of positioning rods 27 are fixedly connected to a support plate 24 that supports the rubber pad 28 after it contacts the ground to increase stability. The right side of the support plate 24 is fixedly connected to a guide block 26 that can be operated by foot. The bottom end of the support plate 24 is fixedly connected to a rubber pad 28 that increases the friction with the ground to further increase stability.

[0020] Reference Figure 1 , Figure 2 The cleaning component 3 includes a scraper 32 for scraping the filter holes inside the filter frame 4. The scraper 32 is slidably connected to the bottom of the inside of the filter frame 4. A support block 33 is fixedly connected to the top of the scraper 32 to drive the scraper 32 to move and provide support for it. A fixed rod 31 is fixedly connected inside the filter frame 4 to support the movement of the support block 33. The support block 33 passes through and is slidably connected to the outer wall of the fixed rod 31. A handle 34 is hinged to the top of the support block 33 to facilitate the movement of the support block 33.

[0021] Working principle: When it is necessary to move the box 1, it can be easily moved by the moving feet 41 on the left and right sides of the box 1. After moving to the target position, first rotate the rotating ring 22, so that the rotating rod 21 drives the limiting blocks 23 on the front and rear sides to rotate along the arc-shaped sliding groove 25 at the top of the fixed block 210 and slide out of the slot 212. At the same time, the rotating rod 21 compresses the torsion spring 29 below the positioning plate 211. Then, step down on the guide block 26 on the right side of the support plate 24, which drives the two sets of positioning rods 27 to slide down along the fixed block 210 until the rubber pad 28 at the bottom of the support plate 24 contacts the ground. At this time, the limiting block 23 and the lower set of arc-shaped slots 212 opposite to the positioning rods 27 are aligned. Then, by... The torsion spring 29 elastically resets the positioning plate 211, rotating rod 21, and limiting block 23, causing the limiting block 23 to engage with the inner wall of the lower set of slots 212, thus limiting the positioning rod 27. This, in turn, increases the friction between the box 1 and the ground through the support plate 24 and the rubber pad 28, achieving stable support. When the support is released and the support plate 24 is retracted, the rotating ring 22 is rotated again to move the limiting block 23 out of the lower slot 212. The guide block 26 is pushed upward to move the positioning rod 27 upward and release the rotating ring 22. When the limiting block 23 and the upper set of slots 212 opposite to the positioning rod 27 are aligned, the limiting block 23 is reset by the torsion spring 29 and engages with the upper slot 212 to complete the positioning. The operation is convenient and the stability is good.

[0022] By flipping up the handle 34 hinged to the top of the support block 33, the handle 34 is pulled to drive the support block 33 to slide along the fixed rod 31 inside the filter frame 4. Simultaneously, the support block 33 drives the scraper 32 at its bottom to slide inside the filter frame 4, scraping and cleaning the filter holes at the bottom of the filter frame 4, removing the iron filings accumulated in the holes, and ensuring the smooth filtration of the filter frame 4.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
