Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a waste discharge device for a numerically controlled milling machine. Background Art

[0002] During the machining process of a CNC milling machine, waste including metal chips and coolant used in the cutting process is generated; the waste collection device of the existing CNC milling machine has the following shortcomings:

[0003] Firstly, conventional waste collection devices often only have a simple collection function. When collecting waste, coolant and solid waste are collected together, which not only increases the difficulty of subsequent processing, but also makes it inconvenient to recycle and reuse the coolant.

[0004] Secondly, existing CNC milling machines must be equipped with waste collection devices when working to ensure that the waste generated during the processing will not pollute the environment or affect the normal operation of the equipment. Therefore, the waste can usually only be cleaned and recycled when the CNC milling machine is not working. This not only interrupts the original continuous production process and increases downtime, but also indirectly affects the overall production efficiency and capacity output.

[0005] Therefore, it is necessary to design a waste discharge device for CNC milling machine to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Reference Figure 1 The utility model provides a waste discharge device for a CNC milling machine, which mainly includes a frame 1 and a transfer trough 2. A fixed trough 3 is obliquely installed on the top of the frame 1. A folding trough 4 is hinged at the lower end of the fixed trough 3. The folding trough 4 can rotate relative to the fixed trough 3. A liquid storage tank 5 is arranged below the fixed trough 3. A support arm 301 is arranged on the side of the fixed trough 3. A folding arm 401 is arranged on the side of the folding trough 4. The upper end of the support arm 301 is fixedly connected to the fixed trough 3, and the lower end is rotatably connected to the liquid storage tank 5; the two ends of the folding arm 401 are rotatably connected to the folding trough 4 and the liquid storage tank 5 respectively. When the folding trough 4 rotates, it can drive the liquid storage tank 5 to rotate with the support arm 301 as the axis through the folding arm 401.

[0020] When working, the transfer trough 2 is set in the frame 1, the fixed trough 3 is opposite to the slag discharge hole of the CNC milling machine, and the folding trough 4 is rotated to be in line with the fixed trough 3. The waste discharged by the CNC milling machine during operation flows into the transfer trough 2 along the fixed trough 3 and the folding trough 4. When the transfer trough 2 is pulled out of the frame 1, the folding trough 4 flips upward, and the liquid storage tank 5 is turned to a horizontal state. The solid waste discharged by the CNC milling machine during operation is temporarily stored in the V-shaped groove formed by the fixed trough 3 and the folding trough 4, and the coolant flows into the liquid storage tank 5 through the hinged gap between the two for temporary storage.

[0021] A support 101 is provided on the frame 1, and a pressure arm 102 is rotatably connected to the support 101. The other end of the pressure arm 102 is rotatably connected to a push arm 103. The upper end of the push arm 103 is rotatably connected to the side of the folding groove 4, so that the push arm 103 can push the folding groove 4 to rotate. A return spring 105 is provided between the pressure arm 102 and the frame 1, and a sliding column 204 cooperating with the pressure arm 102 is provided on the side of the transfer groove 2. When the transfer groove 2 moves along the frame 1, the sliding column 204 will press the pressure arm 102 and then push the folding groove 4 to rotate through the push arm 103. At the same time, in order to limit the transfer groove 2 in the frame 1, a limit rod 104 is also provided inside the frame 1, which is arranged above the sliding column 204 and tangent to the sliding column 204.

[0022] A filter screen 201 is provided inside the transfer tank 2 to separate the solid waste and the coolant. A drain valve 6 is provided at the bottom of the transfer tank 2 to control the discharge of the coolant. In order to facilitate transfer and cleaning, a universal wheel 203 is provided at the bottom of the transfer tank 2 and a handrail 205 is provided on the side. A handle 202 is provided on the filter screen 201 to facilitate the operator to remove and clean the filter screen 201.

[0023] Reference Figure 2 The drain valve 6 includes a drain pipe 601 connected to the transfer tank 2. A sealing ring 605 and a sealing disk 602 are arranged in the drain pipe 601. A plug 603 matched with the sealing ring 605 is arranged on the sealing disk 602 to control the on and off of the drain pipe 601. A plurality of drain holes 604 are also arranged on the sealing disk 602. The plurality of drain holes 604 are arranged in a circle array with the plug 603 as the center. When the plug 603 is separated from the sealing ring 605, the coolant can be discharged through the drain holes 604. A compression spring 606 is arranged between the sealing disk 602 and the bottom of the drain pipe 601. The compression spring 606 presses the sealing disk 602 and the sealing ring 605 to keep the drain pipe 601 in a closed state. When the coolant needs to be discharged, the plug 603 only needs to be pushed out and separated from the sealing ring 605.
