Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a coolant circulation system for a numerical control machine tool. Background Art

[0002] A numerical control machine tool is a machine tool that controls the movement of the machine tool through a computer control system. It can logically process a program with control codes or other symbolic instructions, automatically process parts, and spray coolant on the workpiece and tool during processing. The coolant cools them down and finally flows into the water tank. However, the current machine tool cannot process the debris in the coolant. After long-term use, the debris will block the pipeline and be sprayed out together with the coolant, thus causing certain wear to the workpiece and tool. For this reason, a coolant circulation system for a numerical control machine tool is proposed. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the defect that the debris of the coolant cannot be cleaned in the prior art, and a coolant circulation system for a numerical control machine tool is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A coolant circulation system for a numerical control machine tool includes a housing and a processing table. The processing table is fixedly installed on the top of the housing. A workpiece is placed on a placement plate on the top of the housing. A flow guide plate and a second filter box are respectively fixedly installed inside the housing. A first filter box is fixedly installed on the top of the second filter box. A cleaning component is arranged in both the first filter box and the second filter box. A cooling box is fixedly installed on the inner bottom surface of the housing. The liquid inlet of the cooling box is fixedly connected with the second filter box through a connecting pipe. The liquid outlet of the cooling box is fixedly connected with a liquid supply component.

[0006] In a possible design, the cleaning component includes a lead screw rotatably installed in the first filter box and the second filter box. Sliders are threadedly connected to the circumference of the lead screw. Scrapers are fixedly installed on one side of each slider. Synchronous wheels are fixedly installed at one end of each lead screw, and the two synchronous wheels are sleeved with the same synchronous belt. An L-shaped plate is fixedly installed on one side of the second filter box. A motor is fixedly installed on one side of the L-shaped plate. The output shaft of the motor is fixedly connected with one of the synchronous wheels.

[0007] In a possible design, the liquid supply component includes a water tank and a water pump fixedly installed on the inner bottom surface of the housing. The liquid inlet of the water pump is fixedly connected with the water tank. The liquid outlet of the water pump is fixedly connected with a delivery pipe. The other end of the delivery pipe is fixedly connected with a liquid distribution box. A spray water pipe is fixedly connected to one side of the liquid distribution box.

[0008] In a possible design, baffles are rotatably installed on one side of the first filter box and the second filter box. A set of positioning blocks are fixedly installed on one side of each baffle. A set of springs are fixedly connected to one side of each positioning block, and the other ends of the springs are fixedly connected to the first filter box and the second filter box respectively. Fixed plates are fixedly installed on one side of the first filter box and the second filter box, and the fixed plates are in contact with the collection box.

[0009] In a possible design, a mounting door is hinged to one side of the housing.

[0010] In a possible design, a guide rod is fixedly installed inside the first filter box. A connecting block is slidably connected to the circumference of the guide rod, and one side of the connecting block is fixedly connected to the scraping plate.

[0011] In this application, after the workpiece is placed in a designated place, it is clamped, and the machine tool is started. The tool processes the workpiece. The connecting pipe on one side of the liquid distribution box is connected to the coolant storage tank. The water spraying pipe sprays the coolant onto the tool and the workpiece, cooling them while flushing the chips away. The chips fall into the first filter box through the diversion plate. Larger chips remain on the orifice plate at the bottom, and smaller chips and the coolant together fall into the second filter box for secondary filtration. After filtration, the coolant falls into the cooling box through the connecting pipe for cooling, and then flows into the water tank. By starting the water pump, the coolant in the water tank can be recycled, but the connecting pipe on one side of the liquid distribution box needs to be disconnected before starting the water pump. When there is too much debris inside the first filter box and the second filter box, the motor is started. The motor drives one of the synchronous pulleys to rotate, and then drives the other synchronous pulley to rotate through the synchronous belt, so that the two lead screws rotate. The sliders on the circumference of the lead screws drive the scraping plate to clean the inner walls of the first filter box and the second filter box, and all the scraped debris is pushed into the collection box, solving the problem that too much debris can cause pipeline blockage.

[0012] Beneficial effects:

[0013] In the present utility model, in the coolant circulation system of the numerical control machine tool, the motor drives the synchronous pulleys to rotate, so that the two lead screws rotate. The sliders on the circumference of the lead screws drive the scraping plate to clean the debris inside the first filter box and the second filter box, preventing the debris from blocking the pipeline.

[0014] In the present utility model, in the coolant circulation system of the numerical control machine tool, positioning blocks are installed on one side of the baffles of the first filter box and the second filter box, and springs are installed on one side of the positioning blocks. When the baffle rotates, it can be reset by the spring. Description of the drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Embodiment 1

[0022] Referring to Figures 1 - 4 , the coolant circulation system includes: a housing 1 and a processing table 26. The processing table 26 is fixedly installed on the top of the housing 1. A workpiece 25 is placed on the placement plate at the top of the housing 1. A guide plate 6 and a second filter box 8 are fixedly installed inside the housing 1 respectively. A first filter box 7 is fixedly installed on the top of the second filter box 8. Cleaning components are provided in both the first filter box 7 and the second filter box 8. A cooling box 9 is fixedly installed on the inner bottom surface of the housing 1. The liquid inlet of the cooling box 9 is fixedly connected to the second filter box 8 through a connecting pipe, and the liquid outlet of the cooling box 9 is fixedly connected to a liquid supply component.

[0023] In this embodiment, the structures inside the first filter box 7 and the second filter box 8 are the same, except that the diameter of the orifice plate inside them is different, which is used for secondary filtering of debris in the coolant. A spiral pipe is provided in the cooling box 9, which can make the coolant cool better.

[0024] Referring to Figure 3, the cleaning component includes a lead screw 15 rotatably installed in a first filter box 7 and a second filter box 8. Sliders 16 are threadedly connected to the circumference of the lead screw 15. Scrapers 17 are fixedly installed on one side of each slider 16. Synchronous pulleys 19 are fixedly installed at one end of each lead screw 15, and the two synchronous pulleys 19 are sleeved with the same synchronous belt. An L-shaped plate 21 is fixedly installed on one side of the second filter box 8, and a motor 20 is fixedly installed on one side of the L-shaped plate 21. The output shaft of the motor 20 is fixedly connected to one of the synchronous pulleys 19.

[0025] In this embodiment, the motor 20 drives one of the synchronous pulleys 19 to rotate. Through the synchronous belt, the two synchronous pulleys 19 rotate, thereby driving the corresponding lead screw 15 to rotate, and the sliders 16 on its circumference drive the scrapers 17 to move, so as to clean the debris inside the first filter box 7 and the second filter box 8.

[0026] Refer to Figure 2 , the liquid supply component includes a water tank 13 and a water pump 14 fixedly installed on the inner bottom surface of the housing 1.

[0027] In this embodiment, the liquid distribution box 4 has two liquid inlets, one of which is connected to the delivery pipe 3, and the other is connected to the coolant storage tank through a connecting pipe. First, the coolant in the coolant storage tank is used. When the coolant collected in the water tank 13 is sufficient for recycling, the connection with the coolant storage tank is disconnected, and the filtered coolant is used by starting the water pump 14.

[0028] Refer to Figures 3 - 4 , baffles 10 are rotatably installed on one side of the first filter box 7 and the second filter box 8. A set of positioning blocks 22 are fixedly installed on one side of each baffle 10.

Fixing plates 11 are fixedly installed on one side of the first filter box 7 and the second filter box 8, and the fixing plates 11 are in contact with the collection box 12.

[0029] In this embodiment, when the scraper 17 moves to a specified distance, it will push open the baffle 10, thereby pushing the debris into the fixing plate 11. Since the fixing plate 11 is inclined, the debris on its surface will slide into the collection box 12.

[0030] Refer to Figure 1 , a mounting door 2 is hinged to one side of the housing 1.

[0031] In this embodiment, when the debris in the collection box 12 accumulates to a certain extent, the collection box 12 can be taken out by opening the mounting door 2, and the debris therein can be processed.
