Description

Technical Field

[0001] This invention relates to the field of boring equipment technology, specifically to a new type of precision boring equipment and method for superhard material axles. Background Technology

[0002] With the rapid development of the automotive industry, vehicle weight and load are gradually increasing, making it difficult for traditional axle materials to meet the requirements of high strength and high durability. The development of superhard material axles can provide stronger load-bearing capacity, extend axle service life, reduce maintenance costs, and improve vehicle safety and reliability. In the field of advanced automotive manufacturing, the development of superhard material axles is driving the advancement of precision machining technology. With advancements in technology, truck axles, as key load-bearing and transmission components of the vehicle chassis system, require high-precision and high-efficiency machining techniques to create mounting holes at both ends of the axle. The dimensional accuracy, geometric accuracy, and surface quality of these holes directly affect the bearing fit, operational stability, and service life, thereby impacting the vehicle's load-bearing capacity, transmission efficiency, and driving safety.

[0003] Currently, boring machines or machining centers equipped with boring heads are commonly used to bore axle blanks or semi-finished products. These are fixed to the machine tool using a special fixture, ensuring the machine's axis is aligned with the machine spindle or boring bar axis. The machine spindle drives the boring bar head to rotate and feed, performing the final boring of the pre-machined holes at the axle end. For example, patent application CN120961977A discloses a boring device for producing lightweight axle housings, and patent authorization announcement CN20... Utility model patent 4799995U discloses a three-hole boring machine for electric vehicle axle hubs. When the above-mentioned equipment performs axle boring, it lacks efficient and timely cleaning methods for the large amount of metal chips generated during the cutting process. This results in the chips accumulating and tangling severely inside the boring hole and in the tool head area. The hard and sharp-edged chip fragments are very likely to cause scratches, scoring or even engravings on the surface of the precision hole wall after machining, reducing the machining quality and negatively affecting the geometric accuracy of the hole. Summary of the Invention

[0004] The purpose of this invention is to provide a new type of precision boring machine for superhard material axles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A novel precision boring machine for superhard material axles includes a base, a fixture mechanism, and two sets of boring mechanisms. The two sets of boring mechanisms are symmetrically arranged on the upper sides of both ends of the base, and the fixture mechanism is arranged on the upper side of the base and located between the two sets of boring mechanisms.

The power unit drives the rotary unit to rotate, which in turn drives the cutter head to rotate, and performs boring operations on the inner hole of the axle.

[0014] S4: Metal shavings adsorption. The electromagnet device adsorbs metal shavings during the boring process.

[0015] S401: Cleaning. After metal shavings accumulate on the surface of the electromagnet device, the cleaning component operates to push the accumulated metal shavings upward, ensuring that the surface of the electromagnet device is clean and enabling efficient adsorption.

[0016] Compared with the prior art, the present invention provides a novel precision boring machine and method for superhard material axles, which has the following beneficial effects: (1) During the boring process, the cutting chips are guided to the outside of the electromagnet device and are eventually attracted by the suction device, so that the cutting chips are cleaned up in time; (2) During the impact cleaning of metal cutting chips, since the direction of chip transport is from the outer end of the axle to the middle area, it completely avoids the area where the boring has been completed, thus effectively avoiding scratches, ensuring the smoothness of the inner wall of the boring, and thus ensuring the accuracy of the boring operation. (3) During the boring process, the pump body operates to inject cutting fluid into the guide groove and mix it with the airflow discharged by the suction device to form a gas-liquid mixture, which is discharged through the overflow hole to ensure that the metal chips are subjected to a powerful impact, thereby ensuring the high efficiency of cleaning.

[0030] The sliding assembly includes a power slide device 39 and a guide rail 40. The guide rail 40 is horizontally fixedly installed on the upper side of the base 1. The bottom side of the chassis 2 is horizontally slidably embedded in the guide rail 40. The power slide device 39 is horizontally slidably embedded on the upper side of the guide rail 40, and both sides are fixedly connected to the inner wall of the chassis 2 through the connecting frame 41.

[0031] The axle being machined is made of an ultra-hard material, which can withstand greater loads and impacts. While ensuring high hardness, the material also has good overall toughness, which facilitates lightweight axle design. Furthermore, stress concentration areas are eliminated during the axle production process, allowing stress to be evenly distributed throughout the structure. The ultra-hard material used in the axle can be magnetically attracted, thereby enabling cleaning operations in conjunction with the magnetic attraction of the electromagnet device 8. At the same time, the material of the selected cutting head 32 can meet the requirements for boring operations on ultra-hard material axles.

[0032] When using this equipment to bore a superhard material axle, the axle to be machined is transported to the top of the equipment using a hoisting device, so that the differential mounting hole is vertically aligned with the three-jaw chuck 10, and the two ends of the axle are respectively located on the upper side of the support 11 on both sides. The three jaws of the three-jaw chuck 10 are adjusted so that the jaws contact the inner wall of the differential mounting hole in the middle of the axle, so that the axle is centered. Then, the first telescopic cylinder 13 is shortened, so that the moving jaw 14 at its output end moves closer to the fixed jaw 12, thereby fixing the axle.

[0033] Once the axle is fixed in place, the boring mechanisms on both sides can then perform machining operations on the axle, which is in a fixed state.

[0034] During boring, the electromagnet device 8 is energized and the motor 24 runs, driving the spindle 21 to rotate via the pulley 25 and the transmission belt 26. The spindle 21 drives the sleeve 20 to rotate, the sleeve 20 drives the turntable 27 to rotate, and the turntable 27 drives the cutter head 32 to rotate. At the same time, the two second telescopic cylinders 23 extend, cooperating with the movement of the power slide device 39, which drives the machine housing 2 to move, causing the sleeve 20 to move, which in turn drives the cutter head 32 to move. While moving and rotating, it contacts the axle and performs the boring operation on the axle.

[0035] During the boring operation, the suction device 3 and the pump body 37 are in operation. When the suction device 3 is in operation, the exhaust end exhausts through the drain pipe 33 and is discharged through the first hose 34. It then passes through the guide groove 221, the guide cavity 201, the guide tube 35, the cavity 271, and the connecting pipe 36 in sequence into the drainage cavity 321, and finally is discharged from multiple inclined overflow holes 322. This impacts the boring area and guides the metal chips cut off during boring towards the center of the axle. The cutting chips move along the inside of the axle towards the center and are finally attracted by the electromagnet device 8, thus collecting the cutting chips.

[0036] After the cutting chips are attracted by the electromagnet device 8, the first motor 19 starts and drives the rotating shaft 17 connected to it to rotate, which in turn causes the wheel 15 to drive the conveyor belt 16 to rotate. Multiple scrapers 18 rotate upward with the conveyor belt 16, pushing the cutting chips attracted by the surface of the electromagnet device 8 upward. Finally, the cutting chips are sent from the top to the bottom of the frame 5, and then enter the suction device 3 through the suction pipe 4, where they are attracted by the suction device 3, completing the cleaning.

[0037] During the boring process, the cutting chips are guided to the outside of the electromagnet device 8 and are eventually attracted by the suction device 3, so that the cutting chips are cleaned up in time.

[0038] During the impact cleaning process of metal cutting chips, since the chip conveying direction is from the outer end of the axle to the middle area, it completely avoids the area that has been bored, thus effectively avoiding scratches, ensuring the smoothness of the inner wall of the bored hole, and thus ensuring the accuracy of the boring operation.

[0039] During the boring process, the pump body 37 operates, injecting cutting fluid into the guide groove 221 through the second hose 38. The fluid is then mixed with the airflow discharged from the suction device 3 to form a gas-liquid mixture, which is discharged through the overflow hole 322. This ensures that the metal chips are subjected to a powerful impact, thereby ensuring the high efficiency of the cleaning process.

[0040] A hopper 42 is fixedly installed on the upper side of the base 9. The hopper 42 is tilted and used to receive cutting fluid. A notch is opened on the rear side of the hopper 42 for discharging the collected cutting waste fluid.

[0041] A method for precision boring of a superhard material axle includes the following steps: S1: Fixing, the axle is transferred to the upper side of the fixture mechanism by external hoisting equipment and fixed by clamping; S2: Align the tool, activate the tool holder assembly, so that the tool head 32 contacts the inner hole at the end of the axle; S3: Boring cutting. The power unit drives the rotary unit to rotate, which in turn drives the cutter head 32 to rotate, and performs boring operations on the inner hole of the axle.

[0042] S4: Metal shavings adsorption. Electromagnetic device 8 adsorbs metal shavings during the boring process.

[0043] S401: Cleaning. After metal shavings accumulate on the surface of the electromagnet device 8, the cleaning component operates to push the accumulated metal shavings upward, ensuring that the surface of the electromagnet device 8 is clean and performing efficient adsorption. S5: Flushing. The cutting fluid and airflow form a gas-liquid mixture, which is discharged towards the boring working area to flush away metal chips and ensure efficient cleaning. Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
