Description

TECHNICAL FIELD

[0002] Deep hole drilling machine tool refers to the machine tool equipment specially used in the deep hole drilling process. Deep hole drilling machine tool has wide application range, high rigidity, high precision, high speed, high efficiency, high reliability, large torque and other characteristics. Using deep hole drilling machine tool can save process equipment, shorten production process cycle, ensure product processing quality and improve production efficiency.

[0003] In the machining process of deep hole drilling machine tool, there are usually difficulties in heat dissipation and chip removal. Cutting fluid is usually used to solve the problem of heat dissipation and chip removal. As an auxiliary material, cutting fluid plays a lubricating role in the cutting process, which can reduce the friction between the tool and the workpiece, reduce tool wear, and also reduce the surface temperature of the tool and workpiece friction part, improve the surface quality of the workpiece. Thus, the drill can be cooled and the waste can be taken out through the cutting fluid. The cutting fluid cannot be used again because it contains a large amount of waste. The waste in the cutting fluid cannot be collected, which will cause a lot of waste of cutting fluid and increase the cost of processing.

[0038] And the application on the basis of the comparative document 1, by increasing the following structure.

[0039] Preferably, the oil cooling machine 6 is further installed on the upper end of the box body 1 and acts on the cutting fluid in the second liquid accumulation groove 3;

[0040] The oil cooling machine 6 is preferably an immersed oil cooling machine, which is in contact with the cutting fluid in the second liquid accumulation tank 3 through a partition or a pipe in the heat exchanger. The cooling oil in the oil cooling machine 6 is circulated by the pump, absorbs the heat of the cutting fluid when flowing through the heat exchanger, and then enters the cooling part of the oil cooling machine, such as a wind-cooled fin or a water-cooled condenser, to release the absorbed heat to the surrounding environment or through other media, thereby achieving the cooling and filtering of the cutting fluid at the same time, without the need for external cooling devices, so that the cutting fluid can be directly used.

[0041] The bottom end of the box body 1 is provided with a magnetic plate 7, which can adsorb the metal waste in the cutting fluid through magnetic adsorption.

[0042] When the cutting fluid with waste discharged from the machining tool enters the box body 1, the waste in the cutting fluid discharged earlier will be adsorbed by the magnetic plate 7 at the bottom end of the box body 1, so as to avoid the waste from being stirred up again due to the fluctuation caused by the inflow of the cutting fluid, thereby improving the operation efficiency and stability of the whole oil return and sedimentation system, and ensuring the sedimentation and filtering effect of the cutting fluid waste.

[0043] Secondly, most of the waste can be adsorbed in advance by the magnetic plate 7, thereby reducing the burden of the filter screen 22, prolonging the service life of the filter screen 22, and reducing the replacement frequency.

[0044] The lower end of the box body 1 is provided with a support frame 8, and the support frame 8 and the magnetic plate 7 are provided with a separation mechanism 9. The separation mechanism 9 comprises a horizontal plate 10 arranged on the support frame 8, a screw rod 11 screwed on the horizontal plate 10, a fixed plate 12 rotatably connected to one end of the screw rod 11 and extending toward the magnetic plate 7, and a guide structure 13 arranged between the two ends of the fixed plate 12 and the horizontal plate 10.

[0045] Furthermore, when the waste deposited at the bottom of the box body 1 needs to be cleaned, the screw rod 11 can be rotated (e.g., clockwise), so that the screw rod 11 can drive the fixed plate 12 and the magnetic plate 7 to move, so that the magnetic plate 7 is separated from the bottom of the box body 1, and thus the adsorption force of the magnetic plate 7 on the waste in the box body 1 is eliminated, thereby facilitating the cleaning of the waste in the box body 1 by the staff.

[0046] After cleaning, the screw rod 11 can be rotated in the opposite direction (e.g., counterclockwise), so that the screw rod 11 can drive the fixed plate 12 and the magnetic plate 7 to move toward the box body 1 and tightly adhere to the bottom of the box body 1, so as to generate an adsorption force on the waste in the box body 1 again.

[0047] When the magnetic plate 7 is displaced by rotating the screw rod 11, the guiding structure 13 between the two sides of the fixed plate 12 and the horizontal plate 10 can provide guiding for the fixed plate 12 and the magnetic plate 7, so as to ensure that the rotation of the screw rod 11 can be converted into axial movement of the fixed plate 12 and the magnetic plate 7.

[0048] In the embodiment, the lower end surface of the box body 1 is further provided with three discharge ports 17, and the three discharge ports 17 correspond to the first liquid accumulation groove 2, the second liquid accumulation groove 3 and the third liquid accumulation groove 4 respectively.

[0049] The magnetic plate 7 is provided with three through holes 18, and the three through holes 18 correspond to the three discharge ports 17 respectively.

[0050] When the discharge is needed, the magnetic plate 7 is separated from the box body 1 through the separation mechanism 9, that is, the magnetic plate 7 no longer generates the adsorption force to the internal scrap, and the scrap at the bottom of the first liquid accumulation groove 2, the second liquid accumulation groove 3 and the third liquid accumulation groove 4 can be discharged through the three discharge ports 17 at the lower part of the box body 1, and the three through holes 18 corresponding to the discharge ports on the magnetic plate 7 can ensure the normal discharge of the discharge ports.

[0051] In the embodiment, the guiding structure 13 further includes guiding rods 14 arranged at the two ends of the fixed plate 12, and the horizontal plate 10 is provided with two linear bearing sleeves 15, and the two guiding rods 14 penetrate through the two linear bearing sleeves 15 and are connected in a guiding manner.

[0052] The guiding structure 13 includes the guiding rods 14 at the two sides of the fixed plate 12 and the linear bearing sleeves 15 corresponding to the guiding rods 14 arranged on the horizontal plate 10, and when the fixed plate 12 and the magnetic plate 7 are moved by rotating the screw rod 11, the cooperation of the guiding rods 14 and the linear bearing sleeves 15 can provide the guiding movement limitation for the fixed plate 12, so as to ensure that the fixed plate 12 and the magnetic plate 7 move in the reverse direction according to the plan.

[0053] In the embodiment, the screw rod 11 penetrates through the horizontal plate 10 at the end away from the fixed plate 12 and is connected with a rotating handle 16, and the rotating handle 16 added on the screw rod 11 can facilitate the staff to control and rotate the screw rod 11.

[0054] In the embodiment, the first liquid accumulation groove 2, the second liquid accumulation groove 3 and the third liquid accumulation groove 4 are all provided with cover plates 19, and the cover plates 19 can prevent the external dust from falling into the box body 1 and mixing with the cutting fluid, so as to prevent the increase of the impurities in the cutting fluid.

[0055] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
