Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to an anti-splash waste chip coolant recovery device for numerical control machine tools. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. It controls the machine tool movement by setting digital codes or other symbols to specify the program to run the corresponding commands and after calculation processing, it automatically processes the parts according to the shape and size of the drawing. When the workpiece to be processed is placed on the workbench, it mainly relies on a cutting tool that can move in three dimensions for cutting. During the cutting process, coolant needs to be sprayed on the surface of the workpiece to prevent damage to the tool or material caused by high temperature. Therefore, during the rotation of the cutting edge, the speed will affect the coolant splashing, affecting the processing environment.

[0003] According to the Chinese patent publication number CN116423286B "Anti-splash waste coolant recovery device for CNC machine tools", it mainly describes that the filter cloth is cleaned circumferentially and reciprocatingly up and down by the cleaning ring cleaning room and the convex block, so that the filter cloth is always in the best working state, and the separation efficiency of metal powder particles in the coolant is enhanced. Through the cooperation of the shielding shell, the coolant nozzle and the airflow nozzle, the pipe fittings are cooled while being processed, and the coolant is prevented from splashing circumferentially due to the drill of the drilling device, so that the coolant and waste chips are gathered and collected during the pipe fitting processing. Recovery, the state of the coolant in the temporary storage shell is controlled by the second rotating plate evenly distributed circumferentially, so that larger waste chips can also flow with the coolant, thereby increasing the recovery efficiency of the waste chips. The gravity of the floating plate is adjusted by the accumulation of waste chips on the floating plate, and the floating plate is controlled to move up and down continuously, and the waste chips attached to the first filter plate are scraped and backwashed, so that the first filter plate can achieve a self-cleaning effect when it is close to the inlet and outlet, thereby extending the service life of the first filter plate. In this process, the coolant splashed by the cutting knife will stick to the shielding shell, and the movement effect is slow, which is not convenient for the recovery of the coolant.

[0004] Therefore, an anti-splash waste coolant recovery device for CNC machine tools is proposed to solve the problem that the splashing coolant generated by the cutting tool in the process will stick to the shielding shell, resulting in slow movement, troublesome cleaning, and inconvenient coolant recovery. Utility Model Content

[0005] The technical problem to be solved by the utility model is that part of the coolant will adhere to the shielding shell, which is troublesome to clean. Therefore, an anti-splash waste coolant recovery device for CNC machine tools is proposed.

[0007] As a preferred technical solution of the utility model, one side of the filter frame contacts a limiting plate, and the limiting plate is fixedly connected in the splash shield. The position of the filter frame can be limited by setting the limiting plate.

[0008] As a preferred technical solution of the utility model, the bottom side of the filter frame is in contact with a support roller, and the support roller is rotatably connected in the splash shield. By arranging the support roller, the filter frame can be supported.

[0009] As a preferred technical solution of the utility model, a guide cover is fixedly connected to one side of the splash shield and the bidirectional screw is located in the guide cover. The guide cover can reduce the contact of coolant and debris with the bidirectional screw, causing the bidirectional screw to rotate poorly.

[0010] As a preferred technical solution of the utility model, a connecting sleeve is fixedly connected inside the splash shield, and the connecting sleeve is sleeved with the limiting rod. The connecting sleeve can prevent the coolant from contacting the limiting rod and reduce sticking.

[0011] The utility model has the following advantages: by arranging a bidirectional screw in the machine tool body to control the mutual approach and separation of the splash shields, a shield can be formed during the processing, and at the same time, a guide cover and a connecting sleeve are used to provide a barrier, thereby reducing the contact between the coolant and powder debris and the bidirectional screw, and at the same time, the metal powder in the coolant is filtered by a detachable filter frame, so that the coolant can be recycled.

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3 The shown device is a splash-proof waste chip coolant recovery device for a CNC machine tool, comprising a table 1, a machine tool body 2, a protective door 3, a moving mechanism 4 and a cutting tool 5. The moving mechanism 4 comprises lateral movement and vertical movement, and can drive the support seat to move, and then a slider is installed on the bottom side of the support seat to perform height movement. The slider has a built-in driving motor and drives the cutting tool 5 to rotate. A slider is arranged in the moving mechanism 4, and a bracket 8 is fixedly connected to the bottom side of the slider. A liquid collecting ring 9 is fixedly connected to the bottom end of the bracket 8, and nozzles 10 are fixedly connected to the four sides of the bottom end of the liquid collecting ring 9. Water is pumped from the liquid collecting tank through a water pump, enters the liquid collecting ring 9 through a pipe, and is sprayed out through the nozzle 10. A liquid collecting tank is provided at the center of the upper end of the table 1, and grooves are provided on both sides of the table 1 and a rotating connection is provided in the groove. Two bidirectional screw rods 6 are connected, and the bidirectional screw rods 6 are rotatably connected to the storage table 7. By rotating the bidirectional screw rods 6, the two splash shields 11 are driven to move relative to each other and contact each other to form a closed space to prevent the coolant from splashing due to force. A limit rod 12 is arranged on the side of the storage table 7, and the limit rod 12 is used to provide limitation. The splash shield 11 is sleeved on the limit rod 12, and the splash shield 11 is threadedly connected to the bidirectional screw rod 6. A through hole is opened on the bottom side of the splash shield 11 and a filter frame 13 is inserted in the through hole. The filter frame 13 is located on the bottom side of the splash shield 11 to provide filtering for metal debris and powder in the coolant. By setting a multi-layer structure, the filtering effect is better. A water pump is fixedly connected to one side of the bottom end of the liquid receiving tank and a pipe fitting is fixedly connected to the output end of the water pump. The pipe fitting is fixedly connected to the liquid collecting ring 9 and is internally communicated.

[0018] The splash shield 11 is fixedly connected with a limiting plate 14, which contacts the filter frame 13. By arranging the limiting plate 14 in the splash shield 11, the filter frame 13 can be limited, which is convenient for collecting debris.

[0019] The splash shield 11 is rotatably connected to a support roller 15 , which contacts the filter frame 13 . The support roller 15 is arranged to rotate when the filter frame 13 is moved, thereby providing support for the filter frame 13 .

[0020] A bidirectional screw 6 is arranged in the air deflector 16, and the air deflector 16 is fixedly connected to one side of the splash shield 11. By arranging the air deflector 16, it is possible to prevent chips and coolant from contacting the bidirectional screw 6 when processing chips.

[0021] The limiting rod 12 is sleeved with the connecting sleeve 17 , and the connecting sleeve 17 is fixedly connected in the splash shield 11 . The connecting sleeve 17 is provided to provide a barrier to reduce direct contact between the coolant and the limiting rod 12 .

[0022] Working principle: Start the moving mechanism 4 in the machine tool body 2 to drive the cutting tool 5 to move and contact the mold base, and before the processing process starts, rotate the bidirectional screw 6 to drive the splash guard 11 to move relatively and contact. At this time, the deflector 16 is in contact with the storage table 7, and the filter frame 13 is at the bottom side of the splash guard 11 and provides double-layer filtration. Then, the limit rod 12 is blocked by the connecting sleeve 17 to contact the back-splashed coolant. The filtered coolant is pumped out by a water pump through the pipe fittings into the liquid collecting ring 9, and is evenly sprayed out through the nozzle 10 to cool the mold base. The metal powder in the coolant is filtered through the detachable filter frame 13, so that the coolant can be recycled.
