Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to an environmentally friendly cooling and chip removal drilling machine. Background Technology

[0002] In the field of machining, drilling machines are commonly used equipment, generating a large amount of metal chips during processing. Currently, in traditional cooling and chip-removing drilling machines, the coolant mixes directly with the metal chips during operation. This mixed state makes it difficult to completely separate the coolant during the recovery process, resulting in a large amount of coolant being discarded along with the metal chips, causing serious waste of resources.

[0003] Furthermore, even if some coolant is recovered, it usually lacks the necessary cooling steps before entering the cooling system for reuse. If the recovered coolant is at a high temperature and is directly reused for cooling, its cooling effect will be greatly reduced, failing to meet the strict cooling requirements of drilling machine processing, thus affecting processing quality and efficiency.

[0004] Therefore, proposing an environmentally friendly cooling chip removal drilling machine that can overcome the above-mentioned defects is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an environmentally friendly cooling chip removal drilling machine to solve the problems mentioned in the background art.

[0006] To achieve the above technical objectives, the present invention provides an environmentally friendly cooling and chip removal drilling machine, comprising: a two-axis drilling machine and a translational workpiece table. The translational workpiece table is located below the two-axis drilling machine and has guide channels on both sides. The guide channels are inclined and have a circulating cooling device at their lower end. The circulating cooling device includes a housing, and a coolant chamber and a chip chamber are provided inside the housing. A circulating pump and a solid-liquid separation device are provided on the housing. The inlet of the circulating pump is located in the coolant chamber, and the outlet is connected to the spray system of the two-axis drilling machine. The solid-liquid separation device is driven by the motor of the circulating pump. Its upper end is directly opposite the slag discharge hole at the bottom of the guide channel, and its lower end is located in the coolant chamber. A transfer drawer is provided in the chip chamber.

[0007] Furthermore, the solid-liquid separation device includes a support cylinder with its upper and lower ends open and fixed to the housing. A support plate is installed inside the support cylinder, and an inverted frustum screen cylinder is installed on the support plate. The lower end of the frustum screen cylinder is closed, and its upper end is rotatably connected to the support plate. A baffle ring coaxial with the frustum screen cylinder is installed on the support plate. An opening adjacent to the waste chip chamber is provided on the ring surface of the baffle ring. A scraper is installed inside the opening of the baffle ring. The scraper is inclined and tangent to the inner surface of the frustum screen cylinder. A slag discharge trough is provided on the support cylinder, and the slag discharge trough is directly opposite the transfer drawer.

[0008] Furthermore, a positioning ring is provided on the support plate, and a thrust ball bearing is provided inside the positioning ring. The seat ring of the thrust ball bearing is fixedly connected to the support plate. The upper end of the frustum screen cylinder is folded and connected to the shaft ring of the thrust ball bearing. A pulley is provided on the folded edge of the frustum screen cylinder. Two symmetrical guide wheels are provided on the support plate. The transmission belt between the motor output shaft of the circulating pump and the pulley passes between the two guide wheels.

[0009] Furthermore, the outer wall of the section of the support cylinder inside the coolant cavity is provided with heat dissipation fins, and a fan is provided on the housing directly opposite the heat dissipation fins.

[0010] Furthermore, a splash guard is provided above the baffle ring, and a guide cylinder is provided on the splash guard. The lower end of the guide cylinder is eccentrically positioned with respect to the frustum screen cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model include:

[0012] 1. This utility model utilizes a solid-liquid separation device. A circulating pump motor drives a frustum-shaped screen cylinder to rotate. Under centrifugal force, the coolant passes through the screen holes and separates from the metal shavings. The metal shavings are scraped into a transfer tray by a scraper, achieving efficient recycling. Simultaneously, a filter device is installed at the inlet of the circulating pump to further remove powdery residue from the coolant, improving its purity. Furthermore, heat dissipation fins are installed on the outer wall of the support cylinder, which, together with a fan, accelerates airflow, enhancing the coolant's heat dissipation efficiency. This ensures the coolant is effectively cooled before entering the spray system, guaranteeing cooling performance and improving processing quality and efficiency.

[0013] 2. This utility model uses a frustum screen cylinder combined with a scraper and a baffle ring to quickly and thoroughly separate metal shavings from the coolant, avoiding the discarding of metal shavings with the coolant, reducing resource waste and environmental pollution; moreover, the recovered coolant can be reused in the cooling system after being cooled by the heat dissipation fins and the fan, without the need to add a large amount of new coolant, thus reducing operating costs.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Reference Figure 1 This utility model provides an environmentally friendly cooling and chip removal drilling machine, including a two-axis drilling machine 1 and a translation workpiece table 2. The translation workpiece table 2 is located below the two-axis drilling machine 1, and inclined guide grooves 3 are provided on both sides of it. A circulating cooling device 4 is provided at the lower end of the guide grooves 3.

[0019] Reference Figure 2 The circulating cooling device 4 consists of a housing 401, a circulating pump 406, a solid-liquid separation device 5, and a transfer tray 404. The housing 401 is divided into a coolant chamber 402 and a waste chip chamber 403. The inlet of the circulating pump 406 is located in the coolant chamber 402 and is equipped with a filter to remove powdery slag mixed in the coolant. The outlet is connected to the spray system of the two-axis drilling machine 1. The transfer tray 404 is detachably installed in the waste chip chamber 403. When the drilling machine is working, the circulating pump 406 starts, drawing out the coolant from the coolant chamber 402 and transporting it to the spray system of the two-axis drilling machine 1 to cool the drill bit and the workpiece. After the coolant mixes with the metal chips generated during processing, it flows into the solid-liquid separation device 5 along the guide channel 3.

[0020] Reference Figure 3 The solid-liquid separation device 5 includes a support cylinder 501, which is open at both ends and fixed to the housing 401. A support plate 502 is provided inside the support cylinder 501. An inverted frustum screen cylinder 504 and a positioning ring 503 are installed on the support plate 502. A thrust ball bearing 507 is installed inside the positioning ring 503. The seat ring of the thrust ball bearing 507 is fixedly connected to the support plate 502. The upper end of the frustum screen cylinder 504 is folded and connected to the shaft ring of the thrust ball bearing 507, while the lower end is closed. A pulley 508 is provided on the folded edge of the frustum screen cylinder 504. Two symmetrical guide wheels 509 are provided on the support plate 502. The transmission belt between the motor output shaft of the circulating pump 406 and the pulley 508 passes between the two guide wheels 509, thereby providing power for the rotation of the frustum screen cylinder 504. The guide wheels 509 also serve as guides and tensioners.

[0021] The support plate 502 is also provided with a baffle ring 505 coaxial with the frustum screen cylinder 504. The baffle ring 505 has an opening on its ring surface adjacent to the waste chip chamber 403. An inclined scraper 506 is provided inside the opening and is tangent to the inner surface of the frustum screen cylinder 504. When the mixed liquid is discharged from the bottom of the guide channel 3 into the solid-liquid separation device 5, it falls into the frustum screen cylinder 504. The motor of the circulating pump 406 drives the frustum screen cylinder 504 to rotate. Under the action of centrifugal force, the coolant passes through the screen holes of the frustum screen cylinder 504 and splashes onto the inner wall of the support cylinder 501. The coolant conducts heat to the support cylinder 501 as it travels along the inner wall of the support cylinder 501. In order to improve the cooling effect, heat dissipation fins 510 are provided on the outer wall of the section of the support cylinder 501 inside the coolant chamber 402. A fan 405 is provided on the housing 401 opposite to the heat dissipation fins 510.

[0022] Under the action of centrifugal force, metal shavings overcome gravity and rise along the inner wall of the frustum screen cylinder 504 to the opening of the baffle ring 505. They are then scraped out of the frustum screen cylinder 504 by the scraper 506 and fall into the transfer tray 404 along the slag discharge trough 513 provided on the support cylinder 501. A splash guard 511 is provided above the baffle ring 505, and a guide cylinder 512 is provided on the splash guard 511. The splash guard 511 can prevent the coolant from splashing out during the solid-liquid separation process. The lower end of the guide cylinder 512 is eccentrically set with the frustum screen cylinder 504, which helps the waste liquid to move outward under the action of centrifugal force after falling into the frustum screen cylinder 504, thereby improving the solid-liquid separation effect.

[0023] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
