Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of lathes for machining axles, and more specifically, to a lathe for machining axles. Background Technology

[0002] As a core component of a vehicle's transmission system, the machining accuracy and quality of axles directly affect the vehicle's safety and reliability. With the rapid development of industries such as automobiles and rail transportation, the requirements for the efficiency and precision of axle machining are becoming increasingly stringent.

[0003] However, traditional lathes used for machining axles have many limitations. On the one hand, axle parts are slender and have poor rigidity, making it difficult for traditional lathes to accurately position and stably support them during clamping and machining. This can easily lead to vibration and deformation, compromising machining accuracy and making the clamping process cumbersome, significantly impacting machining efficiency. On the other hand, axle machining generates a large amount of waste. Traditional lathes have poorly designed chip removal structures, causing waste to accumulate in the machining area. This not only hinders the normal flow of cutting fluid, affecting cooling and lubrication, but can also scratch machined surfaces, reducing product quality. Furthermore, cleaning up accumulated waste is extremely difficult, requiring significant manpower and time. Therefore, there is an urgent need to develop a new type of lathe for machining axles to solve the problems of existing lathes in axle part machining and waste removal, thereby improving the overall quality and efficiency of axle machining. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a lathe for machining axles, which solves the technical problem that traditional lathes in the prior art have difficulty in accurately positioning and stably supporting shaft parts during clamping and machining, and are prone to vibration, deformation and other problems, which make it difficult to guarantee machining accuracy.

[0005] According to one aspect, at least one embodiment of this disclosure provides a lathe for machining axles, comprising:

[0006] A lathe carriage and a pair of movable seats, the movable seats being connected to the lathe carriage via a linear drive;

[0007] A cleaning assembly, wherein the cleaning assembly is disposed in the lathe frame;

[0008] The lathe includes a stand and a top mount, wherein the stand is connected to the lathe frame via a transverse linear drive, and the top mount is connected to the stand via a vertical linear drive.

[0010] The support and flipping assembly includes a support shaft rotatably connected within the movable seat. One end of the support shaft is provided with a driven gear, and a drive gear is provided on one side surface of the movable seat. The drive gear is electrically driven to rotate and meshes with the driven gear.

[0011] As a further technical solution, a circular groove is provided inside the support shaft, and through openings are provided on both sides of the circular groove. A stud is rotatably connected inside the circular groove, and a movable rod is movably fitted inside the circular groove and through openings.

[0012] As a further technical solution, the movable rod and the stud are connected by a threaded connection, a reinforcing plate is provided on the support shaft, a stabilizing sleeve is provided on the movable rod, both ends of the stabilizing sleeve are movably fitted inside the reinforcing plate, and one end of the stabilizing sleeve is fitted outside the support shaft.

[0013] As a further technical solution, the cleaning component includes a bottom cavity, which is opened inside the lathe frame. A cleaning port is opened on one side of the bottom cavity, and a collection groove is opened at the bottom of the cleaning port. A push auger is installed in the collection groove, and one end of the push auger extends to the outside of the lathe frame.

[0014] As a further technical solution, a partition is provided inside the bottom cavity, and the partition covers the linear drive part of the moving seat.

[0015] As a further technical solution, the bottom surface of the cavity is an inclined structural surface, and the bottom of the cavity is inclined towards the cleaning port side.

[0017] As a further technical solution, the top of the top seat is provided with several spindle mounting slots, which are distributed at the four opposite corners.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, the support and tilting assembly achieves stable rotation of the support shaft through the meshing of the drive gear and the driven gear, providing precise rotational power for axle machining and solving the problem of accurate positioning of shaft parts on traditional lathes. The threaded engagement between the studs inside the support shaft and the moving rod allows the stabilizing sleeve to flexibly adjust and clamp both ends of the axle, forming a stable support structure that effectively reduces vibration and deformation during machining, ensuring machining accuracy. The cooperation between the reinforcing plate and the stabilizing sleeve guides the linear movement of the moving rod, ensuring uniform distribution of clamping force, improving the reliability of axle clamping, and avoiding machining errors caused by unstable clamping.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-4 As shown, it illustrates a lathe for machining axles according to an embodiment of the present disclosure, comprising:

[0033] A lathe frame 1 and a pair of movable seats 2, the movable seats 2 being connected to the lathe frame 1 via a linear drive;

[0034] Cleaning component 6, which is disposed in the lathe frame 1;

[0035] The stand 3 and the top seat 4 are provided. The stand 3 is connected to the lathe frame 1 by a transverse linear drive, and the top seat 4 is connected to the stand 3 by a vertical linear drive.

[0036] A support flipping assembly 5 is provided on the movable base 2;

[0037] The support and tilting assembly 5 includes a support shaft 5-1, which is rotatably connected to the movable base 2. One end of the support shaft 5-1 is provided with a driven gear 5-2, and one side surface of the movable base 2 is provided with a drive gear 5-3. The drive gear 5-3 is electrically driven to rotate and meshes with the driven gear 5-2. A circular groove 5-4 is formed inside the support shaft 5-1, and openings 5- are formed on both sides of the circular groove 5-4. 5. A stud 5-6 is rotatably connected inside the circular groove 5-4. A movable rod 5-7 is movably fitted inside the circular groove 5-4 and the through 5-5. The movable rod 5-7 and the stud 5-6 are connected by a threaded connection. A reinforcing plate 5-8 is provided on the support shaft 5-1. A stabilizing sleeve 5-9 is provided on the movable rod 5-7. Both ends of the stabilizing sleeve 5-9 are movably fitted inside the reinforcing plate 5-8, and one end of the stabilizing sleeve 5-9 is fitted outside the support shaft 5-1.

[0038] In some examples, a support and tilting assembly 5 is designed to achieve precise support, clamping, and rotation of the axle. This assembly includes a support shaft 5-1 rotatably connected within a movable seat 2. The support shaft 5-1 can rest on both ends of the axle. A drive gear 5-3 on one side is driven by a motor to rotate, which in turn drives the support shaft 5-1 to rotate synchronously through meshing with a driven gear 5-2, providing rotational power for axle machining. The circular groove 5-4 inside the support shaft 5-1 has openings 5-5 on both sides to provide a moving channel for the moving rod 5-7. The stud 5-6 inside the circular groove 5-4 is manually driven to rotate, engaging with the internal thread of the moving rod 5-7 to convert the rotational motion into the axial linear motion of the moving rod 5-7.

[0039] When the stud 5-6 rotates clockwise, the moving rod 5-7 extends outward along the opening 5-5, driving the end retaining sleeve 5-9 to move. The two ends of the retaining sleeve 5-9 are movably fitted inside the reinforcing plate 5-8, which is fixed to the surface of the support shaft 5-1, forming a guide structure to ensure that the retaining sleeve 5-9 does not skew during movement. When the sleeve is fitted outside the support shaft 5-1 and contacts both ends of the axle, it presses the axle firmly between the support shafts 5-1. For example, before machining, by adjusting the stud 5-6 to make the retaining sleeve 5-9 press against both ends of the axle, the drive gear 5-3 drives the support shaft 5-1 to rotate, causing the axle to rotate synchronously, thus cooperating with the lathe tool to complete external turning or thread machining.

[0040] like Figures 1-4 As shown, this embodiment proposes that the cleaning component 6 includes a bottom cavity 6-1, which is opened inside the lathe frame 1. A cleaning port 6-2 is opened on one side of the bottom cavity 6-1. A collection groove 6-3 is opened at the bottom of the cleaning port 6-2. A push auger 6-4 is installed in the collection groove 6-3. One end of the push auger 6-4 extends to the outside of the lathe frame 1.

[0041] In some examples, a cleaning component 6 is designed to achieve efficient collection and removal of turning chips. This component includes a bottom cavity 6-1 located inside the lathe frame 1. The inclined bottom surface guides the chips to gather towards the cleaning port 6-2. The collection groove 6-3 at the bottom of the cleaning port 6-2 provides installation space for the push auger 6-4 and can collect the chips. The diameter of the spiral blades of the push auger 6-4 matches the width of the collection groove 6-3. It is driven to rotate by a motor. When the chips fall into the collection groove 6-3, the axial thrust of the spiral blades pushes the chips along the groove to the outside of the lathe frame 1, where a container can be placed for collection.

[0042] During turning, iron or aluminum chips fall into the bottom cavity 6-1 due to gravity, slide along the inclined bottom surface towards the cleaning port 6-2, and then enter the collection tank 6-3, where they are continuously discharged by the pusher auger 6-4. This design prevents chips from accumulating in the lathe's working area, avoiding machining errors caused by chips entangled in the tool or affecting the axle positioning. Automated chip removal also reduces the frequency of manual cleaning, improving the lathe's continuous machining efficiency. The detachable structure of the pusher auger 6-4 facilitates periodic cleaning of entangled long chips, ensuring the long-term stable operation of the chip removal system.

[0043] For example, such as Figure 3 As shown, a partition 7 is provided inside the bottom cavity 6-1, and the partition 7 covers the linear drive part of the movable seat 2.

[0044] In some examples, a partition 7 installed inside the cavity 6-1 covers the linear drive portion of the moving seat 2, forming a protective barrier. The partition 7 is made of metal plate or engineering plastic and has a semi-enclosed structure. Its edges are fixed to the inner wall of the cavity 6-1 by bolts, precisely avoiding the movement trajectory of the drive components. When machining chips fall into the cavity 6-1, the partition 7 can prevent the chips from splashing onto the precision components such as the linear drive guide rail and lead screw, avoiding jamming or wear caused by chip accumulation.

[0045] For example, such as Figure 3 As shown, the bottom surface of the cavity 6-1 is an inclined structural surface, and the bottom of the cavity 6-1 is inclined towards the cleaning port 6-2.

[0046] In some examples, the bottom surface of the cavity 6-1 is designed with an inclined structure, tilting towards the cleaning port 6-2 to optimize chip removal efficiency using gravity. The angle between the inclined surface and the horizontal plane is typically 10° to 20°, gradually decreasing from the edge of the lathe carriage 1 towards the cleaning port 6-2, forming a natural gravity slope. Chips generated during turning slide down into the cavity 6-1 with the cutting fluid or their own weight, quickly converging along the inclined surface to the cleaning port 6-2, preventing accumulation in the corners of the cavity 6-1.

[0047] For example, such as Figure 3 As shown, the bottom surface of the collection groove 6-3 is a semi-circular structure, and the inner diameter of the collection groove 6-3 matches the diameter of the push auger 6-4.

[0048] In some examples, the bottom surface of the collection trough 6-3 has a semi-circular structure with a diameter that matches the diameter of the pushing auger 6-4, achieving efficient conveying of waste and residue-free discharge. The curvature of the bottom of the semi-circular trough 5-4 precisely matches the outer contour of the auger blades. When the auger rotates, the blades can closely follow the bottom of the trough to push the waste, preventing debris from getting stuck between the bottom of the trough and the blades.

[0049] For example, such as Figure 1 As shown, the top of the top seat 4 has several spindle mounting slots 8, which are distributed at the four opposite corners.

[0050] In some examples, the spindle mounting slots 8 on the top of the top seat 4 are distributed at the four opposite corners, forming a symmetrical rigid support structure. The four mounting slots are rectangularly distributed, and locating keys and bolt holes are provided in the slots. The spindle is fixed in the mounting slots by bolts, and the locating keys ensure that the spindle axis is perpendicular to the lathe machining reference.

[0051] In practical use: Fix the lathe frame 1 to the machining site. Adjust the position of a pair of movable seats 2 on the lathe frame 1 using the linear drive device, so that the support shaft 5-1 of the support tilting assembly 5 is aligned with both ends of the axle. Place the axle between the support shafts 5-1, rotate the stud 5-6 inside the support shaft 5-1. The stud 5-6 is threaded into the movable rod 5-7, causing the movable rod 5-7 to extend along the through-hole 5-5, so that the stabilizing sleeve 5-9 is fitted onto the outside of the support shaft 5-1 and presses against both ends of the axle. Start the drive gear 5-3 on the side surface of the movable seat 2. The electric drive rotates it and meshes with the driven gear 5-2, causing the support shaft 5-1 and the axle to rotate synchronously. Adjust the position of the stand 3 using the transverse linear drive and adjust the height of the top seat 4 using the vertical linear drive. Install the machining tool in the spindle mounting groove 8 of the top seat 4 to machine the rotating axle. Waste generated during processing falls into the bottom cavity 6-1 of the lathe frame 1, slides along the inclined bottom surface to the cleaning port 6-2, enters the collection groove 6-3 and is pushed out of the lathe frame 1 by the auger 6-4. After processing is completed, the stud 5-6 is rotated in the opposite direction to loosen the stabilizing sleeve 5-9 and the axle is taken out.
