Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for CNC machine tools, and in particular to a diversion device and a CNC machine tool. Background Technology

[0002] CNC machine tools continuously generate large amounts of waste material consisting of mixed metal shavings and coolant during cutting, grinding, and other machining processes. Current mainstream treatment methods typically employ a two-stage separation process: first, the mixed waste material is collected in a collection tank, and then transferred to a separation unit for liquid-solid separation via a separate conveying device. This method has significant drawbacks: separation lag: the waste material remains immersed in coolant during transport, increasing the amount of liquid carried by the shavings, reducing the efficiency of subsequent centrifugal separation or filtration, and resulting in a moisture content exceeding 15% in the separated waste material; system redundancy: the separation module, conveying module, and collection tank are separately arranged, occupying 30%-40% of the space around the machine tool, and the complex piping connections lead to high maintenance costs.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0022] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a drainage device according to an embodiment of this application; Figure 2 This is a schematic diagram of a drainage device in an embodiment of this application, omitting the drive component. As shown, the device includes: at least one receiving trough 100, fixed to the waste discharge end of a CNC machine tool, the receiving trough 100 having a first inclined surface 110; a diversion trough 200, connected to the receiving trough 100, the first inclined surface 110 facing the diversion trough 200; a drainage channel 300, connected to the outer wall of the diversion trough 200, the connection between the drainage channel 300 and the diversion trough 200 having a filter hole 210; water in the diversion trough 200 enters the drainage channel 300 through the filter hole 210 and is discharged; and a drive component 400, disposed in the diversion trough 200; the drive component 400 is used to drive the waste in the diversion trough 200 to move towards the connection side of the drainage channel 300. After the waste enters the diversion tank 200, the drive component 400 immediately pushes it towards the drainage channel 300. During this process, the coolant, under the pressure of the waste and gravity, continuously seeps into the drainage channel 300 through the filter holes 210, achieving dry and wet separation within the tank. Compared with traditional solutions, the waste retention time is shortened, the moisture content of the separated debris decreases, and the coolant recovery rate is improved. At the same time, the independent separation module and conveying module are eliminated, effectively reducing the equipment size and improving space utilization.

[0023] See Figure 1 Furthermore, in this embodiment, the drive assembly 400 includes: a worm gear 410 disposed within the diversion channel 200; and a drive motor 420 disposed at one end of the diversion channel 200 away from the drainage channel 300, with the power output end of the drive motor 420 connected to the worm gear 410. By rotating the worm gear 410 to generate axial thrust, it provides strong conveying force for wet waste; the blades of the worm gear 410 compress debris and discharge residual coolant, reducing the moisture content of the separated waste; by embedding the worm gear 410 within the diversion channel 200, an independent conveying mechanism is eliminated, reducing the equipment's footprint; and the external design of the drive motor 420 prevents coolant from entering the motor compartment.

[0024] See Figure 2Furthermore, in this embodiment, two receiving troughs 100 are provided, and the two receiving troughs 100 are respectively perpendicularly connected to the diversion trough 200. The first inclined surface 110 of the receiving trough 100 faces the diversion trough 200 perpendicularly. The double troughs cover multiple discharge ports of the machine tool, improving the waste collection rate; double-sided feeding avoids jamming of the worm gear 410 caused by single-sided accumulation; the vertical inclined surface allows waste to slide into the diversion trough 200 along the shortest path, reducing splashing.

[0025] See Figure 2 Furthermore, in this embodiment, the receiving trough 100 is sealed to the diversion trough 200. The sealing structure prevents coolant and debris from overflowing, keeping the working environment clean; the sealing structure also maintains a stable fluid pressure field within the diversion trough 200, enhancing drainage efficiency.

[0026] Preferably, during processing, the edges of the receiving trough 100 and the diversion trough 200 are directly connected into one piece by continuous welding to avoid the overflow of coolant and debris.

[0027] See Figure 3 , Figure 3 This is a side view of a drainage device according to an embodiment of this application.

[0028] Furthermore, in this embodiment, the drainage channel 300 is fixed below any one of the receiving troughs 100. One end of the drainage channel 300 surrounds the bottom and sides of the diversion trough 200 to form a filter hole 210 area, and the other end of the drainage channel 300 is provided with a drain outlet. The surrounding design expands the filter hole 210 area, accelerating liquid seepage; by setting the drainage channel 300 below the receiving trough 100, space utilization can be improved and the device volume can be reduced.

[0029] See Figure 2 Furthermore, in this embodiment, a second inclined surface 310 is provided within the drainage channel 300, and the inclination direction of the second inclined surface 310 is opposite to the inclination direction of the first inclined surface 110. The second inclined surface 310 and the first inclined surface 110 form a guiding angle, driving the liquid to flow directionally through the filter screen to the drain outlet.

[0030] See Figure 4 , Figure 4 This is a bottom view of a drainage device according to an embodiment of this application.

[0031] Furthermore, in this embodiment, the cross-section of the drainage channel 300 gradually decreases from the side near the diversion trough 200 to the side of the drain outlet. The tapering structure generates a Venturi effect, increasing the drainage flow rate; the narrowing section of the channel compresses suspended particles to pass through, preventing secondary clogging of the filter pores.

[0032] See Figure 2Preferably, the diversion channel 200 is tubular. The tubular structure improves the uniformity of liquid permeation in the filter hole 210 area.

[0033] Preferably, the gap between the inner wall of the circular tube of the diversion channel 200 and the blade of the worm gear 410 is ≤2mm, so that there is no waste material jamming during the conveying process.

[0034] See Figure 2 Preferably, the drainage channel 300 is connected to the outer wall of the end of the diversion trough 200. The end connection ensures that the filtration zone is away from the main propulsion section of the worm gear 410, preventing waste from squeezing and clogging the filter holes; the water content of the waste in the trough is lowest when it moves to the end, and drainage at this time can reduce liquid residue.

[0035] Furthermore, this embodiment provides a drainage method using a drainage device, comprising the following steps:

[0036] Waste material is discharged from the CNC machine tool into the receiving trough 100;

[0037] The waste material slides into the diversion channel 200 along the first inclined surface 110 of the receiving trough 100;

[0038] The drive motor 420 starts, and the worm gear 410 pushes the waste material toward the drainage channel 300 side;

[0039] Coolant seeps into drainage channel 300 through filter hole 210 and is discharged from drain outlet along second inclined surface 310;

[0040] The dewatered waste is pushed to the end of the diversion tank 200 for manual collection, thus completing the diversion.

[0041] In a second aspect, this utility model provides a CNC machine tool, wherein the CNC machine tool is equipped with the aforementioned diversion device. By adopting the diversion device, the overall energy consumption of the machine is reduced, the number of additional power units is reduced, and the overall energy consumption of the machine tool decreases; the failure rate of the waste disposal system decreases, and the annual maintenance hours are reduced.

[0042] As can be seen from the above, in the diversion device of this utility model, after the waste enters the diversion tank, the drive component immediately pushes it towards the drainage channel. During this process, the coolant is squeezed by the waste and subjected to gravity, continuously seeping into the drainage channel through the filter holes, thus achieving dry and wet separation within the tank. Compared with traditional solutions, the waste retention time is shortened, the moisture content of the separated debris decreases, and the coolant recovery rate is improved. At the same time, the independent separation module and conveying module are eliminated, effectively reducing the equipment volume and improving space utilization.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
