Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a protective device used for CNC machine processing. Background Art

[0002] CNC machining machine tools are a widely used high-precision machining method. Their main working method is to use a cutting head to rotate at high speed to cut the desired shape on the surface of the workpiece. In this process, it is usually necessary to spray cutting fluid on the cutting area for lubrication and heat dissipation to ensure that the cutter head and the workpiece will not be excessively worn and deformed, thereby improving the workpiece processing effect and the service life of the cutter head. However, the high-speed rotating cutter head often splashes the cutting fluid all around, thereby polluting the environment around the equipment. At the same time, some cutting fluid formulas contain toxic and harmful ingredients to the human body, increasing the safety risks of workers using the equipment. At the same time, there is a lack of means to recycle and reuse the used cutting fluid, resulting in a large amount of loss in CNC machining. Utility Model Content

[0005] The protective cover is provided with limit slide rails on one side corresponding to the machine tool, and a protective door is slidably arranged inside the limit slide rail to facilitate the operation of the internal machine tool.

[0006] The protection cover is located outside one side of the protection door and a control console is installed to facilitate the control of electrical components in the equipment.

[0007] The base is provided with a drainage hole connecting the liquid collecting tank and the recovery filter tank, a filter and a drainage pipe are provided at the bottom of the recovery filter tank, the drainage pipe is connected to the recovery pump, the recovery pump is connected with a cutting fluid recovery pipe connected to the cutting fluid storage tank, and a recovery liquid one-way valve is provided on the cutting fluid recovery pipe to facilitate filtering and recovering the cutting fluid.

The infusion pump is connected to a cutting fluid delivery pipe connected to the machine tool, and a delivery check valve is arranged on the cutting fluid delivery pipe to facilitate the replenishment and recycling of the cutting fluid.

[0009] After adopting the above structure, the protective device for CNC machining of the utility model has the following advantages: the protective cover of the utility model can block the splashing of cutting fluid to avoid polluting the surrounding environment, thereby achieving the protection of the staff, and at the same time the inclined surface on the base can guide the splashed cutting fluid into the liquid collection tank and filter and recycle it for reuse.

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0014] Combined with Figure 1-2 A protective device for CNC machining, comprising a base 1, a protective cover 2 is installed around the base 1, a machine tool 5 is installed on the base 1 inside the protective cover 2, a liquid collecting tank 7 is provided in the base 1 below the machine tool 5, and inclined surfaces 8 inclined toward the liquid collecting tank 7 are arranged around the base 1. A cutting fluid storage tank 19 and a recovery filter tank 11 connected to the liquid collecting tank 7 are arranged on the back of the base 1, a recovery pump 13 is arranged between the recovery filter tank 11 and the cutting fluid storage tank 19 to transport liquid, and an infusion pump 16 for transporting liquid is arranged between the cutting fluid storage tank 19 and the machine tool 5.

[0015] The protective cover 2 is provided with limiting slide rails 6 on the upper and lower sides corresponding to the machine tool 5, and a protective door 3 is slidably arranged inside the limiting slide rail 6. A control console 4 is installed outside the protective cover 2 on one side of the protective door 3. The protective door 3 that can be pushed and pulled can be used to provide thorough protection when the machine tool 5 is in operation, thereby greatly reducing the harm of cutting fluid to workers.

[0016] The base 1 is provided with a drainage hole 9 connecting the liquid collecting tank 7 and the recovery filter tank 11. The bottom of the recovery filter tank 11 is provided with a filter 10 and a drainage pipe 12. The drainage pipe 12 is connected to a recovery pump 13. The recovery pump 13 is connected with a cutting fluid recovery pipe 14 connected to a cutting fluid storage tank 19. A recovery liquid one-way valve 15 is provided on the cutting fluid recovery pipe 14. The filter 10 is a common cutting fluid filter on the market, so it is not elaborated in detail. After the cutting fluid entering the recovery filter tank 11 is filtered by the filter 10, the filtered cutting fluid can be recovered into the cutting fluid storage tank 19 by the recovery pump 13. The recovery liquid one-way valve 15 can prevent liquid reflux.

[0017] A refill opening 20 is provided at the top of the cutting fluid storage tank 19, and the bottom of the cutting fluid storage tank 19 is connected to the inlet of the infusion pump 16. The infusion pump 16 is connected to a cutting fluid delivery pipe 17 connected to the machine tool 5. A delivery check valve 18 is provided on the cutting fluid delivery pipe 17.
