[0002] When machining mechanical parts on a machining center, it is usually necessary to use coolant to cool the mechanical grinding area. This method consumes coolant very quickly. Therefore, it can be recycled to realize the reuse of coolant without much change in the properties of the solution components. In the coolant recycling and filtering work, structures such as sponges can be used to first filter large cutting wastes, and then cooperate with other structures to finally realize the reuse of coolant.

[0003] However, in the cutting working environment, cutting wastes are easily accumulated in front of the filtering pipeline and are likely to block the liquid inlet position of the filtering pipeline, making it difficult to clean, and ultimately resulting in difficulties in recycling coolant waste liquid.

[0030] A high-efficiency coolant return mechanism for a machining center provided by an embodiment of the present utility model is used to remove blockages in the pipeline during the coolant return process of the machining center, which can conveniently simplify the pipeline cleaning work to reduce the difficulty of waste liquid recovery. In addition, the machine can be cleaned without stopping the machine, without affecting the normal use of the equipment. In order to achieve the function of facilitating the cleaning of blockages, the mechanism is provided as follows:

[0031] A return pipe 1 for returning excess coolant to the liquid supply tank, which can provide power for the liquid through the pumping of a water pump to supply it back to the water source.

[0032] A support frame 2, as Figure 1 shown, the support frame 2 includes a support body 201 and sealing plates 202 provided on both sides of the support body 201. Specifically, first communication ports 203 are provided on both of the two sealing plates 202, and the pipe body parts of the return pipe 1 are respectively connected and arranged on the corresponding first communication ports 203.

[0033] A rotating cylinder 3 is rotatably arranged on one side of the support frame 2, and both sides of the rotating cylinder 3 are respectively abutted against the corresponding sealing plates 202. A plurality of communication holes are arranged in a circumferential array along the axis of the rotating cylinder 3 on the rotating cylinder 3, and a filter element 4 is arranged in each communication hole. The rotating cylinder 3 can be driven by a driving device 5 to rotate, so that the through hole where the filter element 4 is located can be connected to the return pipe 1. Through the above design, during normal operation, the filter element 4 is in a state of connecting the pipeline of the return pipe 1. According to Figure 2As shown, that is, the liquid in the return pipe 1 flows from the right side to the left side. After passing through the filter element 4, the waste is filtered and removed. When it is necessary to clean the pipeline of the return pipe 1, there are two working modes. One is to offset the pipeline where the filter element 4 is located, and then process the waste accumulated inside the rotating cylinder 3. At this time, a chamber for storing waste needs to be reserved inside the rotating cylinder 3. The specific method can be referred to the description later. Another working mode is that after the rotating cylinder 3 drives the filter element 4 to offset, the state of the return pipe 1 is disconnected, and the waste accumulated in the return pipe 1 can be discharged at the break position of the return pipe 1. In this case, it is required that the rotating cylinder 3 does not have a chamber for storing waste by itself, and by rotating the rotating cylinder 3, the pipeline of the return pipe 1 can be formed into a disconnected exposed state. This can be achieved by specially designing the shape of the rotating cylinder 3 or the layout of the sealing plate 202. Through the above methods, the processing work of the waste in front of the filter element 4 can be simplified, and the accumulation of waste can be prevented, which is beneficial to the recycling of the coolant.

[0034] For a high-efficiency coolant return mechanism of a machining center provided by an embodiment of the present invention, in order to form a chamber for storing waste inside the rotating cylinder 3, the length of the filter element 4 can be set to be less than the length of the communication hole, and the filter element 4 can be set to be abutted and fixed on one side of the communication hole. The space formed by the other side and the wall surface of the rotating cylinder 3 is the space for storing waste. After rotating the passage where the filter element 4 is located out of the working position, the through hole where the filter element 4 is located is exposed, and the filter element 4 is pushed out in the reverse direction, then the waste can be directly discharged from the corresponding communication port. In order to improve the stability of the position of the filter element 4 or form a stable waste storage space, a butt joint pipe 6 can be installed in the communication hole. The butt joint pipe 6 is in the shape of a hollow cylinder, and the butt joint pipe 6 abuts on one side of the filter element 4. As a preferred implementation manner, the total length of the filter element 4 and the butt joint pipe 6 is the length of the inner cavity of the rotating cylinder 3. In order to ensure the sealing fit, a sealing ring 9 can be provided on the part of the two side surfaces of the rotating cylinder 3 surrounding the through hole or on the part surrounding the first communication port 203 to prevent or reduce the degree of liquid leakage.

[0035] For a high-efficiency coolant return mechanism of a machining center provided by an embodiment of the present invention, in order to facilitate the automatic cleaning of the accumulated waste from the pipeline, the waste can be discharged from the corresponding channel by using a reverse acting force. Specifically, it can be referred to Figure 1As shown, the setting mechanism further includes a cleaning pipe 7. Specifically, second communication ports 204 are also provided on both of the two sealing plates 202. The pipe body part of the cleaning pipe 7 is respectively connected and arranged on the corresponding second communication ports 204. During the rotation of the rotary drum 3, the through hole where the filter element 4 is located can be connected to the cleaning pipe 7. An electromagnetic valve is provided on the cleaning pipe 7 and it is connected to a cleaning water source. It should be noted that the water flow direction of the cleaning pipe 7 is opposite to that of the return pipe 1. The waste in the waste storage space can be discharged by the water pressure through the pumping action of the water pump, so that the blockage at the front end of the filter element 4 can be cleaned without manual intervention, further simplifying the cumbersome steps of manual intervention.

[0036] For a high-efficiency coolant return mechanism of a machining center provided by an embodiment of the present invention, in order to facilitate the centralized storage and treatment of the discharged waste, the setting mechanism further includes a waste box 8. Specifically, the liquid outlet pipe section of the cleaning pipe 7 connected to the second communication port 204 can be set to be bent downward in an L shape, as Figure 1 shown. A plurality of filter mesh openings are provided on the waste box 8, and the opening of the waste box 8 is set to correspond to the position of the liquid outlet of the L-shaped pipe section. At this time, when the waste is flushed out by the reverse water flow, it can directly fall into the waste box 8. The filter mesh openings on the waste box 8 drain the water, leaving behind machining debris and some other impurities, thus simplifying the manual operation and making the operation more convenient.

[0037] For a high-efficiency coolant return mechanism of a machining center provided by an embodiment of the present invention, in order to reduce the pressure required for flushing out impurities by water pressure, the rotating shaft of the rotary drum 3 can be set parallel to the horizontal plane. At this time, both the filtering action and the flushing action can reduce the influence of the gravity of the debris, which is more conducive to the exclusion.

[0038] For a high-efficiency coolant return mechanism of a machining center provided by an embodiment of the present invention, since the symmetric design of the support frame 2 may not be convenient for installing the rotary drum 3. Specifically, the support frame 2 is set to be composed of a first frame body and a second frame body, and arc fitting surfaces are respectively provided on the first frame body and the second frame body. The arc fitting surfaces are used to clamp the outer surface of the rotary drum 3. A through port for exposing the rotating shaft part of the rotary drum 3 is formed after the first frame body and the second frame body are assembled, and a bearing matching with the rotating shaft of the rotary drum 3 is rotatably arranged on the through port to enable it to support the rotary drum 3 and roll accurately.

[0039] An efficient coolant return mechanism for a machining center provided by an embodiment of the present utility model. In order not to affect the continuous recovery of coolant during the impurity removal process, at least two filters 4 installed on the rotating cylinder 3 can be provided, and at least one of them can perform impurity removal while the other is performing filtration work. In order to improve the accuracy of the connection between the passage where the filter 4 is located and the corresponding pipeline, a detection device for detecting the rotation position of the rotating cylinder 3 can be provided on the support frame 2. As a preferred embodiment, the detection device can be a photoelectric sensor, and in this case, a shielding member for shielding the light source can be provided at the corresponding position of the rotating cylinder 3 (not shown in the figure).

[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
