Description

Technical Field

[0001] This utility model relates to the technical field of milling machine processing devices, specifically to a device for assisting chip removal in deep hole milling. Background Technology

[0002] Milling deep holes is a process that uses the spindle rotation and feed motion of a milling machine to machine holes with a large length-to-diameter ratio. Currently, when milling deep holes in sheet metal, due to the large length-to-diameter ratio of the deep holes, the chips need to be discharged in reverse from the narrow hole, resulting in high path resistance. Especially when the hole depth exceeds 100mm, the chips are prone to accumulate and jam inside the hole, leading to tool wear or breakage.

[0003] The commonly used chip removal methods currently available mostly involve removing the sheet metal from the milling machine's processing platform and then removing the chips from the holes. This method greatly increases the labor intensity of workers, and at the same time, it requires frequent repetition, resulting in low processing efficiency and failing to meet processing requirements. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides an auxiliary chip removal device for deep hole machining on milling machines. It has a simple structure, is easy to operate, and has a high degree of automation. It can effectively reduce the labor intensity of workers, improve machining efficiency, and meet machining needs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for assisting chip removal in deep hole machining on a milling machine includes a mounting base. A lifting mechanism is provided on one side of the mounting base. The lifting mechanism includes a lead screw, a vertical displacement guide rail, and a feeding seat. The feeding seat is mounted on the vertical displacement guide rail via a vertical displacement slide and can be driven to move along the vertical displacement guide rail by the lead screw. A scale is provided on one side of the vertical displacement guide rail.

[0007] Preferably, the feeding seat is provided with a feeding trough, and elastic support blocks are provided on both sides of the feeding trough.

[0008] Preferably, the elastic support block includes a spring and a fixing block. The material feeding groove is provided with a mounting hole, which is inclined from bottom to top. One end of the spring is installed in the mounting hole, and the other end of the spring is connected to the fixing block.

[0009] Preferably, the fixing block has a funnel-shaped opening at its front end, and a plurality of fixing teeth are provided inside the opening.

[0010] Preferably, the bottom center of the feeding seat is provided with a chip discharge port, the width of which is smaller than the width of the feeding seat.

[0011] Preferably, the bottom of the chip discharge port is provided with a V-shaped guide slope.

[0012] Preferably, the lead screw is connected to a crank or motor for driving its rotation.

[0013] The beneficial effects of this utility model are as follows: A lifting mechanism is provided on one side of the mounting base. The lifting mechanism includes a lead screw, a vertical displacement guide rail, and a feeding seat. The feeding seat is mounted on the vertical displacement guide rail via a vertical displacement slide and can move along the vertical displacement guide rail via the lead screw. A scale is provided on one side of the vertical displacement guide rail. In use, the mounting base is installed on the worktable of the milling machine, the feeding seat is aligned with the milling machine's cutting tool, and a tool retraction distance is reserved. The vertical displacement slide drives the feeding seat to set the missing machining distance for machining deep holes, and the distance is precisely controlled by referring to the scale.

The structure is simple, operation is convenient, and the degree of automation is high. It can effectively reduce the labor intensity of workers, improve processing efficiency, and meet processing needs. Attached Figure Description

[0018] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments:

[0019] This embodiment: as follows Figure 1-3 As shown, a milling machine deep hole machining device for assisting chip removal includes a mounting base 10. A lifting mechanism is provided on one side of the mounting base 10. The lifting mechanism includes a lead screw 11, a vertical displacement guide rail 12, and a feeding seat 13. The lead screw 11 is connected to a crank for driving its rotation. The feeding seat 13 is mounted on the vertical displacement guide rail 12 via a vertical displacement slide 14 and is connected to the lead screw 11. It can be driven to move along the vertical displacement guide rail 12 by the lead screw 11. A scale is provided on one side of the vertical displacement guide rail 12. The lead screw 11 is manually rotated by the crank to convert the rotational motion into linear motion, which drives the feeding seat 13 to move up and down. It is precise, stable, and low in cost.

[0020] The feeding seat 13 is provided with a feeding groove 15. Elastic support blocks are provided on both sides of the feeding groove 15. Each elastic support block includes a spring and a fixing block. The feeding groove 15 has mounting holes 16, which are inclined upwards. One end of the spring is installed in the mounting hole 16, and the other end is connected to the fixing block. Through the extension and contraction of the spring, it can adapt to workpieces of different sizes within a certain range, eliminating the need for frequent fixture changes and improving versatility. Simultaneously, during processing, machine tool vibration or cutting force may cause workpiece displacement; the elastic force of the spring can dynamically offset some of the vibration energy, reducing the risk of workpiece loosening. The fixing block has a trumpet-shaped opening at its front end, and the opening contains several... The fixed teeth, with their flared openings, guide the workpiece to quickly align with the feed groove 15, reducing the difficulty of alignment during manual placement. Simultaneously, the fixed teeth abut against the workpiece surface, increasing friction to prevent slippage under cutting force. The feed seat 13 has a chip discharge port 17 at its bottom center. The width of the chip discharge port 17 is smaller than the width of the feed seat 13, and the bottom of the chip discharge port 17 has a V-shaped guide slope. Located at the bottom center, the chip discharge port 17 utilizes gravity and the flushing effect of the cutting fluid to allow chips to flow along the inclined groove bottom towards the chip discharge port 17. This prevents chips from falling into the feed seat 13 during tool retraction, thus avoiding chip accumulation, entanglement of the workpiece, or blockage of the fixture, making chip removal more convenient and faster.

[0021] In use, the mounting base 10 is installed on the worktable of the milling machine, the feeding seat 13 is aligned with the milling machine's cutting tool, and a retraction distance is reserved. The feeding seat 13 is driven by the up-and-down displacement slide 14 to set the missing machining distance for machining deep holes, and the distance is precisely controlled by referring to the scale. When removing chips, there is no need to frequently remove the plate. The feeding seat 13 is moved downward by the up-and-down displacement slide 14 to achieve rapid tool retraction and chip removal. The structure is simple, the operation is convenient, and the degree of automation is high. It can effectively reduce the labor intensity of workers, improve processing efficiency, and meet processing needs.

[0022] It should be noted that in this embodiment, the lead screw 11 can also be driven to rotate by a motor, and the user can choose according to processing requirements, production costs and processing efficiency.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
