Description

Technical Field

[0001] This utility model relates to the field of lubrication and cooling technology, specifically to a micro-lubrication and cooling device for parts processing. Background Technology

[0002] In machining, efficient and precise lubrication and cooling are key factors in improving machining quality and reducing tool wear. With the rapid development of high-speed cutting and precision machining technologies, traditional lubrication and cooling methods can no longer meet the dual requirements of energy conservation, environmental protection and machining efficiency in modern machining. Micro-lubrication technology has become a research hotspot due to its characteristics of low oil consumption and good cooling effect. However, existing devices generally have problems such as inaccurate lubricant coverage and insufficient adjustment flexibility.

[0003] Traditional lubrication and cooling devices often employ fixed nozzles or simple manually adjustable structures. Their spray angle and direction cannot be dynamically adjusted according to machining conditions, resulting in uneven lubricant coverage and low utilization, especially in complex curved surfaces or multi-axis machining where lubrication blind spots are prone to occur. Furthermore, excessive lubricant not only causes waste but also pollutes the working environment. While existing micro-lubrication technologies can reduce lubricant usage, they still suffer from insufficient spray precision and poor adaptability. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a micro-lubrication and cooling device for parts processing, which solves the problems mentioned in the background.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a micro-lubrication and cooling device for parts processing, comprising a fixed frame and a nozzle, wherein a mounting frame is rotatably mounted on the fixed frame, a mounting rod is slidably mounted on the mounting frame, a mounting seat is provided below the mounting rod, and the nozzle is located below the mounting seat; a position adjustment mechanism for adjusting the position of the mounting seat is provided inside the mounting rod, and an angle adjustment mechanism for adjusting the angle of the nozzle is provided inside the mounting seat.

[0008] The angle adjustment mechanism includes a rotating column rotatably mounted in a mounting base, a first worm gear sleeved on the rotating column, a first worm rotatably mounted in the mounting base and meshing with the first worm gear, a rotating rod rotatably mounted in the rotating column, a second worm gear sleeved on the rotating rod, a second worm rotatably mounted in the rotating column and meshing with the second worm gear, and a nozzle rotatably connected to the rotating column via a mounting shaft, with the mounting shaft and rotating rod being perpendicular to each other.

[0009] Preferably, a toothed ring is fitted onto the mounting bracket, and a drive wheel is rotatably mounted inside the fixing bracket, with the drive wheel meshing with the toothed ring.

[0010] Preferably, angle sensors are fixedly mounted on both the mounting base and the rotating column, and the first worm and the second worm are respectively fixedly connected to the output shaft of the corresponding angle sensor.

[0011] Preferably, a first bevel gear is sleeved on the rotating rod, and a second bevel gear is sleeved on the mounting shaft, with the second bevel gear meshing with the first bevel gear.

[0012] Preferably, the position adjustment mechanism includes a lead screw rotatably mounted in the mounting bracket, the lead screw passing through a mounting rod slidably mounted on the mounting bracket and threadedly connected to the mounting rod.

[0013] Preferably, a first adjusting rod is slidably installed inside the mounting rod, and a second adjusting rod is slidably installed inside the first adjusting rod. The end of the second adjusting rod away from the mounting rod is fixedly connected to the mounting base. A threaded rod is rotatably installed inside the mounting rod, and the lower end of the threaded rod passes through the first adjusting rod and is threadedly connected to the first adjusting rod.

The key blocks and keyways are correspondingly arranged, and the threaded tube is slidably connected to the threaded rod through the key blocks and keyways.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a micro-lubrication and cooling device for parts processing, which has the following beneficial effects:

[0017] The multi-directional adjustable nozzle structure significantly improves the precision and adaptability of micro-lubrication and cooling. The angle adjustment mechanism, employing a combination of dual worm gear transmission and bevel gears, along with an angle sensor, achieves precise positioning of the nozzle in three-dimensional space. This allows the lubricant to dynamically track the tool's cutting point, ensuring full lubrication and cooling coverage during complex surface machining. The position adjustment mechanism, through a combined transmission of a lead screw, a first adjusting rod, and a second adjusting rod, forms a three-axis linkage adjustment (X, Y, Z). Combined with the rotation function of the mounting bracket, the nozzle can be positioned arbitrarily within a certain radius of the working area, effectively improving lubrication efficiency compared to traditional fixed structures. The modularly designed rotating column and mounting shaft are orthogonally distributed, and combined with the self-locking characteristics of the two-stage worm gear, this ensures the stability of multi-angle spraying while avoiding misalignment caused by machining vibration, thus increasing lubricant utilization and reducing splash contamination.

The nozzle 5 is rotatably connected to the rotating column 701 through the mounting shaft 707. The mounting shaft 707 and the rotating rod 704 are perpendicularly distributed.

[0026] In this embodiment, reference Figure 4 As shown, a gear ring 8 is fitted onto the mounting bracket 2, and a drive wheel 9 is rotatably mounted inside the fixed bracket 1. The drive wheel 9 meshes with the gear ring 8. Angle sensors 710 are fixedly mounted on both the mounting base 4 and the rotating column 701. The first worm 703 and the second worm 706 are respectively fixedly connected to the output shaft of the corresponding angle sensor 710. A first bevel gear 708 is fitted onto the rotating rod 704, and a second bevel gear 709 is fitted onto the mounting shaft 707. The second bevel gear 709 meshes with the first bevel gear 708.

At the same time, the second worm gear 706 drives the second worm wheel 705 to rotate the rotating rod 704. Through the meshing first bevel gear 708 and second bevel gear 709, the torque of the rotating rod 704 is transmitted to the mounting shaft 707 fixed to the nozzle 5, thereby adjusting the pitch angle of the nozzle 5.

Combined with the feedback from the angle sensor 710, a closed-loop control is formed, enabling the nozzle 5 to accurately point to the processing area in three-dimensional space.

[0027] In this embodiment, reference Figure 2 and Figure 3As shown, the position adjustment mechanism 6 includes a lead screw 601 rotatably mounted within the mounting bracket 2.

[0028] In this embodiment, the first worm gear 703 drives the first worm wheel 702 to rotate the rotating column 701 horizontally, thereby adjusting the azimuth angle of the nozzle 5 around the vertical axis. Simultaneously, the second worm gear 706 drives the second worm wheel 705 to rotate the rotating rod 704. Through the meshing first bevel gear 708 and second bevel gear 709, the torque of the rotating rod 704 is transmitted to the mounting shaft 707, which is fixedly connected to the nozzle 5, thus adjusting the pitch angle of the nozzle 5. The self-locking characteristics of the two worm gear mechanisms ensure stability after positioning at any angle. Combined with feedback from the angle sensor 710, a closed-loop control is formed, allowing the nozzle to... The nozzle 5 can accurately point to the machining area in three-dimensional space. The rotation of the mounting bracket 2 is achieved by the drive wheel 9 engaging with the toothed ring 8 to achieve circumferential positioning in the horizontal plane. The rotation of the lead screw 601 drives the mounting rod 3 to move longitudinally along the mounting bracket 2, forming radial adjustment. The threaded rod 604 drives the extension and retraction of the first adjusting rod 602 and the second adjusting rod 603 through the linkage of the keyway 605 and the threaded tube 606, respectively, to achieve precise vertical height adjustment of the mounting base 4 and the nozzle 5.
