Description

Technical Field

[0001] This invention relates to the field of deep hole machining equipment technology, specifically a deep hole milling machine. Background Technology

[0002] Deep hole machining is one of the key processes in the field of mechanical manufacturing. Holes with a depth-to-diameter ratio (the ratio of hole depth to hole diameter) greater than 10 are generally defined as deep holes. These holes are widely used in many fields such as hydraulic cylinders, coal mining machinery, and aerospace components. Traditional deep hole machining mostly relies on milling processes, using milling cutters to complete the machining of deep holes.

[0003] In the process of deep hole milling, existing deep hole milling equipment suffers from the problem that the narrow internal space of the deep hole causes the chips generated during milling to accumulate inside the hole. This not only affects the smoothness of milling but may also scratch the machined hole wall, reducing machining accuracy. At the same time, during deep hole machining, the tool is in a narrow hole space with poor heat dissipation. Overheating of the tool can lead to accelerated wear, shorten tool life, and thus increase machining costs.

[0004] Therefore, it is necessary to provide a new deep hole milling device to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the deep hole milling equipment provided by the present invention has the following beneficial effects: 1.

The coolant cools the cutting edge of the milling cutter and the inside of the deep hole through the internal cooling channel and seepage hole. At the same time, the universal bamboo joint spray pipe sprays the outside of the milling area. Combined with the cooling box and the cooling plate for circulating cooling, it effectively solves the problem of poor heat dissipation in deep hole machining, reduces milling cutter wear, and extends its service life. 2. The waste material and waste liquid absorption component in this invention uses the first expansion joint (60° angle) to draw milling waste material and waste liquid in real time, and the second expansion joint to clean residual waste material in deep holes. Combined with the filtration and separation of the solid-liquid separation box, it avoids chip accumulation that scratches the hole wall and hinders milling, ensuring continuous and smooth processing and improving processing quality. Third, this invention achieves stable workpiece clamping through the cooperation of a concave positioning seat, a positioning screw, and a clamping seat. Combined with a moving adjustment module driven by longitudinal and transverse screws, the machining points of the workpiece and the milling cutter can be precisely adjusted, improving the accuracy of deep hole machining. Furthermore, the recovered coolant, after solid-liquid separation, filtration, and cooling, is circulated back to an external coolant return tank for reuse, reducing processing costs. The separation drawer and the first filter cloth can be quickly disassembled and assembled, facilitating waste removal and component maintenance, thus improving the ease of use of the equipment.

A conveying square tube 1704 is fixedly installed at the bottom of the cooling box 17. Multiple cooling plates 1705 are fixedly installed at the bottom of the conveying square tube 1704. Multiple cooling fans 1706 are fixedly installed at the top of the base 1. The multiple cooling fans 1706 are respectively located below the multiple cooling plates 1705. An installation port is opened on the second support leg 16. The conveying square tube 1704 passes through the installation port and does not contact the inner wall of the installation port.An isolation plate is fixedly installed inside the receiving hopper 2. The first support leg 4 passes through the isolation plate and is fixedly connected to it. Two second filter cloths are fixedly installed on the isolation plate by bolts. A transfer pump 18 is fixedly installed on the base 1. The inlet port of the transfer pump 18 is fixedly connected to the receiving hopper 2. One end of the discharge pipe 19 is fixedly installed at the outlet port of the transfer pump 18. The other end of the discharge pipe 19 extends to the top of the cooling box 17, and the discharge pipe 19 is fixedly connected to the solid-liquid separation box 13 by reinforcing ribs. By performing double cooling on the recovered coolant, it can be recycled.

[0026] In this embodiment, the external pipe on the coolant pump 11 is connected to the external coolant tank, and the delivery square pipe 1704 is connected to the external coolant return tank.

[0027] When this deep hole milling machine is working, the workpiece to be processed is first placed in the concave positioning seat 5, and the positioning screw 501 is turned to push the clamping seat 502 to slide along the first limiting rod in the concave positioning seat 5, so as to finally achieve the positioning, clamping and fixing of the workpiece; then the moving adjustment module is operated. When the longitudinal screw 301 rotates, it drives the longitudinal moving plate 302, the L-shaped support arm 303 and the transverse slide 304 to make longitudinal displacement. Rotating the transverse screw 308 can drive the connecting seat 305 to move the processing table 306 laterally, thereby accurately adjusting the processing point between the workpiece and the milling cutter 906.

[0028] After the position adjustment is completed, the control shaft 10 drives the active bevel gear to mesh with the driven bevel gear, driving the internal thread sleeve 7 to rotate. With the limiting and guiding effect of the second limit rod, the lifting screw 8 drives the connecting frame 9, the mounting plate 901 and the milling cutter 906 to descend to the deep hole machining station. At the same time, the rotary motor 903 in the connecting frame 9 drives the coolant cone 902 to rotate at high speed through the meshing transmission of two sets of spur gears. The coolant cone 902 drives the milling cutter 906 to rotate synchronously through the bolt locking structure of the main mounting flange 904 and the auxiliary mounting flange 905, performing deep hole milling on the workpiece. The sealing ring ensures the sealing performance between the coolant cone 902 and the auxiliary mounting flange 905.

[0029] During the milling operation, the cooling system is activated. First, the first electric push rod 1201 drives the first liquid guide pipe 1104 to adjust its height, bringing the universal bamboo nozzle 1106 down to the milling area. Then, the coolant pump 11 draws external coolant, which is delivered through the drain pipe 1101 to the inverted U-shaped branch pipe 1102 and then splits into two first corrugated pipes 1103. One stream of coolant flows through the second liquid guide pipe 1105 into the coolant cone 902, and then into the internal cooling channel 907 of the milling cutter 906. It seeps out through multiple seepage holes 909 on the inner wall of the spiral chip removal groove 908, providing internal cooling to the cutting edge and deep hole of the milling cutter 906. The other stream of coolant is delivered through the first liquid guide pipe 1104 to the universal bamboo nozzle 1106, so that the coolant is precisely sprayed onto the milling area through the nozzle for external spray cooling, reducing the high temperature generated by the milling operation from all directions.

[0030] Simultaneously, the waste material and waste liquid absorption assembly operates synchronously. First, the second electric push rod 1501 is activated, and its output shaft lowers the first suction pipe 1502 and the second suction pipe 1503 to the height of the milling area. At this time, the valve on the first suction pipe 1502 opens and the valve on the second suction pipe 1503 closes. Then, the negative pressure pump 1303 is activated, generating negative pressure on the feed side of the first reamer 1504. The first reamer 1504 faces the end face of the machining table 306 at a 60° angle, thus continuously sucking up the debris and waste liquid generated during milling. After the deep hole machining is completed, the horizontal... The screw 308 moves the deep hole below the second expansion joint 1505, and the valve on the second suction pipe 1503 is opened to suck up the residual waste material and waste liquid inside the deep hole. The sucked waste material and waste liquid are sent into the solid-liquid separation tank 13 through the second corrugated pipe 14. The separation drawer 1301 in the solid-liquid separation tank 13 adopts a porous structure to achieve solid-liquid filtration and separation. Solid debris is retained in the separation drawer 1301, and waste liquid drips downward. The sealing plate 1302 and the mouth-shaped sealing ring achieve a seal. The separation drawer 1301 can be quickly disassembled and assembled by the engagement of the elastic clip and the wedge-shaped clip, which is convenient for cleaning waste residue.

[0031] After solid-liquid separation, the waste liquid is continuously drawn in by the negative pressure pump 1303 and introduced into the cooling box 17 through the diversion pipe. The first filter cloth 1701 in the cooling box 17 filters the waste liquid again to remove impurities. The inclined flow plates 1702 arranged on both sides extend the flow path of the waste liquid. The fan assembly 1703 works with the airflow to accelerate the initial heat dissipation of the waste liquid. When the waste liquid flows through the conveying square pipe 1704, multiple sets of cooling plates 1705 at the bottom cool the waste liquid. The cooling fan 1706 simultaneously dissipates heat for the cooling plates 1705 to ensure the cooling effect. At the same time, the waste liquid scattered in the receiving hopper 2 is filtered by the second filter cloth and then conveyed by the conveying pump 18 through the discharge pipe 19 to the top of the cooling box 17, and enters the cooling cycle process to realize the recycling and cooling of the coolant and waste liquid. The cooled coolant is returned to the coolant return tank for subsequent use. Thus, the whole set of equipment completes the entire process of deep hole milling, real-time cooling, chip removal and absorption, and solid-liquid separation and cooling of waste liquid.

[0032] Compared with related technologies, the deep hole milling equipment provided by the present invention has the following beneficial effects: 1. The cooling component in this invention adopts a combination of internal cooling and external spraying. The coolant cools the cutting edge of the milling cutter 906 and the inside of the deep hole through the internal cooling channel 907 and the seepage hole 909. At the same time, the universal bamboo joint spray pipe 1106 sprays the outside of the milling area. Combined with the circulating cooling of the cooling box 17 and the cooling plate 1705, it effectively solves the problem of poor heat dissipation in deep hole machining, reduces the wear of the milling cutter 906, and extends its service life. 2. The waste material and waste liquid absorption component in this invention uses the first expansion joint 1504 (60° angle) to draw milling waste material and waste liquid in real time, and the second expansion joint 1505 to clean the residual waste material in the deep hole. Combined with the filtration and separation of the solid-liquid separation box 13, it avoids the accumulation of chips that scratch the hole wall and hinder milling, ensures continuous and smooth processing, and improves processing quality. Third, this invention achieves stable workpiece clamping through the cooperation of concave positioning seat 5, positioning screw 501 and clamping seat 502. With the help of the moving adjustment module driven by longitudinal screw 301 and transverse screw 308, the machining points of the workpiece and milling cutter 906 can be precisely adjusted to improve the machining accuracy of deep holes. In addition, the recovered coolant is recycled back to the external coolant return tank after solid-liquid separation, filtration and cooling, so as to achieve reuse and reduce processing costs. The separation drawer 1301 and the first filter cloth 1701 can be quickly disassembled and assembled, which facilitates waste cleaning and component maintenance and improves the ease of use of the equipment.
