Description

Technical Field

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

[0002] In the automotive manufacturing industry, axles, as key components that transmit power and support the vehicle body, directly determine the vehicle's driving stability and safety through their machining accuracy. Lathes used for machining automotive axles require precise cutting of multiple features such as the axle's outer diameter, steps, and threads, making them the core equipment in axle manufacturing. With the increasing demand for high-strength and multi-specification automotive axles, the shortcomings of traditional general-purpose lathes have become increasingly apparent: existing general-purpose lathes generally suffer from operational inconvenience in axle machining, requiring the design of special tooling for different axle specifications. This not only extends the machining preparation cycle but also significantly increases production costs, making it difficult to meet the demands of efficient and economical axle production.

[0003] Traditional general-purpose lathes are designed for machining common parts, such as fixtures and tool holders. However, automotive axles are mostly long shafts, and their length, diameter, and step spacing vary between different car models. During machining, the standard three-jaw chuck of a general-purpose lathe is unable to stably hold long shafts, and the cutting forces can easily cause the axle to wobble, affecting machining accuracy. Furthermore, there is a lack of dedicated tool layouts adapted to the multi-feature machining of axles, requiring frequent tool changes and tool angle adjustments, making operation cumbersome. To solve these problems, companies need to design dedicated clamping fixtures and tool positioning fixtures for each axle specification. Fixture design and manufacturing consume significant time and money, and subsequent maintenance and storage also incur additional costs.

[0004] Therefore, the development of specialized lathes that do not require additional tooling design and can be adapted to the machining of axles of various specifications has become an urgent need to reduce axle manufacturing costs and improve production efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a lathe for machining automobile axles, which solves the technical problem that existing general-purpose lathes are generally inconvenient to operate when machining axles.

[0006] According to one aspect, at least one embodiment of this disclosure provides a lathe for machining automobile axles, comprising: The lathe body, top seat, and tool holder are provided. The top seat is connected to the top of the lathe body via a vertical linear drive, and the tool holder is connected to the surface of the top seat via a horizontal linear drive. A pair of uprights and a workpiece driving assembly are provided. The uprights are fixed at both ends of the upper surface of the lathe body. The uprights are T-shaped in shape. The workpiece driving assembly is mounted on the uprights. A clamping and cleaning assembly is disposed between the uprights; The workpiece driving assembly includes a driving disk, which is rotatably connected to one side of the stand by a horizontal electric drive. A telescopic cylinder is horizontally mounted on the other side of the stand, and the output end of the telescopic cylinder is rotatably connected to a driven disk. The driving disk and the driven disk are located on the same axis.

[0007] As a further technical solution, a transmission cavity is provided on the side surface of the upright frame, and a pair of uprights are vertically arranged in the transmission cavity. A lifting seat is vertically slidably connected to the uprights. A second cylinder is vertically installed at the bottom of the upright frame, and the output end of the second cylinder is connected to the lifting seat. A horizontal support roller is horizontally rotatably connected between the lifting seats.

[0008] According to another aspect, in at least one embodiment of the present invention, the clamping and cleaning assembly includes a pair of transverse cavities, each of which is opened at both ends of the side surface of the upright frame. Each transverse cavity is connected to a movable seat via a horizontal linear drive, and a collection cylinder is horizontally rotatably connected to the side surface of a pair of movable seats on one side of the upright frame.

[0009] As a further technical solution, the surface of the collecting cylinder is provided with several collecting ports around its circumference. One end of the collecting cylinder is an open structure, and a pair of movable seats on the side surface of the upright frame on the other side are provided with supporting inner frames. One end of the supporting inner frame is rotatably fitted into the open part of the collecting cylinder.

[0010] As a further technical solution, a slag discharge avoidance port is provided at the bottom of the inner support frame, and a pusher auger is provided in each of the collection cylinders. The pusher auger is electrically driven to rotate and is connected between a pair of movable seats.

[0011] As a further technical solution, a leak-proof cover is fixedly connected between a pair of opposing movable seats. The leak-proof cover is slidably fitted outside the collection cylinder. One side of the leak-proof cover has an open structure. A side clamping roller is rotatably connected to one side of the leak-proof cover, and an upwardly inclined shovel plate is fixedly connected to it.

[0012] As a further technical solution, both the shovel plate and the side clamping roller are located at the lower end of the opening of the leak-proof wrapping sleeve.

[0013] As a further technical solution, the contact surfaces of the drive disc and the driven disc with the axle are both anti-slip structural surfaces.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the workpiece drive assembly solves the problems of easy wobbling and cumbersome operation when machining long shafts on traditional lathes through multi-directional support and precise drive design. The drive plate and driven plate clamp the axle from both ends, and the anti-slip contact surface ensures stable power transmission; the cross support roller is lifted from the bottom by the second cylinder, forming a three-point support, which greatly improves the rotational stability of long shafts and avoids sagging deformation in the middle section. The guide structure of the column and lifting seat ensures precise adjustment of the cross support roller height to adapt to shafts of different diameters. This structure can stably clamp shafts of multiple specifications without additional special tooling, reducing tooling change time, while ensuring the coaxiality of shaft rotation, improving machining accuracy, and meeting the dual requirements of automotive shafts for machining stability and adaptability.

[0023] like Figures 1-4 As shown, it illustrates a lathe for machining automobile axles according to an embodiment of the present disclosure, comprising: The lathe body 1, the top seat 2, and the tool holder 3 are provided. The top seat 2 is connected to the top of the lathe body 1 by a vertical linear drive, and the tool holder 3 is connected to the surface of the top seat 2 by a horizontal linear drive. A pair of uprights 4 and a workpiece driving assembly 5 are provided. The uprights 4 are fixed at both ends of the upper surface of the lathe body 1. The uprights 4 are T-shaped in general. The workpiece driving assembly 5 is mounted on the uprights 4. A clamping and cleaning assembly 6 is disposed between the uprights 4; The workpiece driving assembly 5 includes a driving disk 5-1, which is rotatably connected to one side surface of the stand 4 via horizontal electric drive. A telescopic cylinder 5-2 is horizontally mounted on the other side surface of the stand 4. The output end of the telescopic cylinder 5-2 is rotatably connected to a driven disk 5-3. The driving disk 5-1 and the driven disk 5-3 are located on the same axis. A transmission cavity is opened on the side surface of the stand 4. A pair of columns 5-4 are vertically arranged in the transmission cavity. A lifting seat 5-5 is vertically slidably mounted on the columns 5-4. A second cylinder 5-6 is vertically mounted upward at the bottom of the stand 4. The output end of the second cylinder 5-6 is connected to the lifting seat 5-5. A horizontal support roller 5-7 is rotatably connected between the lifting seats 5-5.

[0024] In some examples, to achieve stable rotation and precise positioning of the automobile axle during the turning process and to avoid wobbling during rotation due to the axle's long length or center of gravity shift, a workpiece drive assembly 5 is designed. This assembly includes a drive disk 5-1 on the side surface of one of the support frames 4, which is driven by horizontal electricity to rotate and provide rotational power to the axle. The output end of the telescopic cylinder 5-2 on the side surface of the other support frame 4 is rotatably connected to the driven disk 5-3. When the telescopic cylinder 5-2 extends, it can push the driven disk 5-3 towards the drive disk 5-1, cooperating with the drive disk 5-1 to press the axle from both ends, thereby achieving axial positioning of the axle. The coaxial design of the drive disk 5-1 and the driven disk 5-3 ensures that the axle's axis is aligned during rotation, avoiding machining errors caused by eccentric rotation.

[0025] A pair of columns 5-4 within the transmission cavity on the side surface of the upright frame 4 provide vertical sliding guides for the lifting seat 5-5. The output end of the second cylinder 5-6 at the bottom of the upright frame 4 is connected to the lifting seat 5-5, forming a lifting drive structure. The extension or retraction of the second cylinder 5-6 can drive the lifting seat 5-5 to move vertically along the columns 5-4, thereby adjusting the height of the horizontally rotating cross support rollers 5-7 connected between the lifting seats 5-5. This allows the cross support rollers 5-7 to lift the axle from the bottom, forming a three-point support with the drive discs 5-1 and driven discs 5-3 at both ends. This significantly improves the stability of the axle during rotation, especially suitable for the processing requirements of long axles, preventing bending deformation of the middle section of the axle due to gravity. The horizontal rotation design of the cross support rollers 5-7 ensures that they rotate synchronously with the axle, avoiding sliding friction between them and causing wear on the axle surface.

[0026] During operation, the axle is placed on the cross support roller 5-7. The telescopic cylinder 5-2 pushes the driven plate 5-3 to press against one end of the axle, so that the other end of the axle is in contact with the drive plate 5-1. The second cylinder 5-6 adjusts the height of the cross support roller 5-7 until it is in contact with the bottom of the axle. The drive plate 5-1 rotates, causing the axle, driven plate 5-3, and cross support roller 5-7 to rotate synchronously. Three-point support ensures stable rotation, and axis alignment ensures accurate machining. The coordinated operation of all components achieves stable rotation drive of the axle, meeting the requirements of turning operations.

[0027] like Figures 1-4 As shown in the figure, the clamping and cleaning assembly 6 in this embodiment includes a pair of horizontal cavities 6-1, each of which is opened at both ends of the side surface of the upright frame 4. Each horizontal cavity 6-1 is connected to a movable seat 6-2 via a horizontal linear drive. A collection cylinder 6-3 is horizontally rotatably connected to the side surface of the pair of movable seats 6-2 on one side of the upright frame 4. The collection cylinder 6-3 has several collection ports 6-4 around its circumference, and one end of the collection cylinder 6-3 is open. A supporting inner frame 6-5 is provided on the side surface of the pair of movable seats 6-2 on the other side of the upright frame 4. One end of the supporting inner frame 6-5 is rotatably fitted. Inside the opening of the collection cylinder 6-3, the bottom of the inner support frame 6-5 is provided with a slag discharge clearance port 6-6. Each collection cylinder 6-3 is provided with a pusher auger 6-7. The pusher auger 6-7 is electrically driven and rotatably connected between a pair of moving seats 6-2. A leak-proof cover 6-8 is fixedly connected between a pair of opposing moving seats 6-2. The leak-proof cover 6-8 is slidably fitted on the outside of the collection cylinder 6-3. One side of the leak-proof cover 6-8 has an open structure. A side clamping roller 6-9 is rotatably connected to one side of the leak-proof cover 6-8, and an upwardly inclined shovel plate 6-10 is fixedly connected to it.

[0028] In some examples, in order to achieve lateral stability support and efficient collection of waste chips during axle turning, and to avoid waste chip splashing during turning that pollutes the environment or affects machining accuracy, a clamping and cleaning assembly 6 is designed. This assembly includes movable seats 6-2 in the transverse cavities 6-1 at both ends of the side surface of the stand 4, which can be adjusted laterally by horizontal linear drive. A pair of opposing movable seats 6-2 move closer or further away from the sides of the axle to adapt to axles of different diameters.

[0029] The collection cylinder 6-3, which is horizontally rotatably connected to the side surface of one of the movable seats 6-2, cooperates with the inner support frame 6-5 of the other movable seat 6-2. One end of the inner support frame 6-5 is rotatably fitted into the opening of the collection cylinder 6-3, which provides rotational support for the collection cylinder 6-3 without affecting the synchronous movement of the collection cylinder 6-3 with the movable seat 6-2.

[0030] The collection port 6-4 around the surface of the collection cylinder 6-3 can be aligned with the area where waste chips are generated during turning. The waste chips generated during turning enter the collection cylinder 6-3 under the action of centrifugal force or gravity. The pusher auger 6-7 inside the collection cylinder 6-3 is driven by electricity to rotate, which can push the collected waste chips to one end of the collection cylinder 6-3. Finally, the waste chips are discharged through the slag discharge avoidance port 6-6 at the bottom of the inner support frame 6-5, realizing continuous collection and centralized treatment of waste chips. The leak-proof wrapping sleeve 6-8 fixed between a pair of relatively movable seats 6-2 is slidably fitted on the outside of the collection cylinder 6-3. The opening structure on one side is adapted to the axle position, which can prevent waste chips from splashing from the connection gap between the collection cylinder 6-3 and the movable seat 6-2, thereby improving the waste chip collection efficiency.

[0031] The side clamping roller 6-9, rotatably connected to one side of the leak-proof cover 6-8, can conform to the axle surface from the side, forming multi-directional support with the bottom cross support roller 5-7, further enhancing the stability of the axle during rotation; the upward-inclined shovel 6-10 can guide the waste chips scattered on the axle surface to the collection port 6-4 of the collection cylinder 6-3, preventing waste chips from accumulating in the processing area. The horizontal linear drive ensures precise adjustment of the moving seat 6-2, and the continuous operation of the pushing auger 6-7 ensures smooth waste chip conveying.

[0032] During operation, the movable seat 6-2 moves the collecting cylinder 6-3 and the side clamping roller 6-9 closer to the axle. The side clamping roller 6-9 clamps the axle, and the turning chips are guided by the scraper plate 6-10 and enter the collecting cylinder 6-3 through the collecting port 6-4, and then discharged by the push auger 6-7. Lateral clamping ensures stability, and synchronous collection maintains cleanliness. All components work together to provide stable support for the axle and handle the chips, meeting the requirements of turning operations.

[0033] For example, such as Figure 3 As shown, the shovel plate 6-10 and the side clamping roller 6-9 are both located at the lower end of the opening of the leak-proof wrapping sleeve 6-8.

[0034] In some examples, the design of the scraper plate 6-10 and the side clamping roller 6-9 located at the lower end of the opening of the leak-proof sleeve 6-8 maximizes the function of both while avoiding mutual interference. Due to gravity, turning chips tend to fall downwards. The scraper plate 6-10 at the lower end can accurately catch these chips and guide them to the collection port 6-4 of the collection cylinder 6-3, reducing the amount of chips falling to the ground or accumulating in the machining area.

[0035] For example, such as Figure 1 As shown, the contact surfaces of the drive disk 5-1 and the driven disk 5-3 with the axle are both anti-slip structural surfaces.

[0036] In some examples, the anti-slip structure of the contact surfaces between the drive disc 5-1, the driven disc 5-3, and the axle significantly increases the friction between them and the axle. The axle rotates relying on the power transmission of the drive disc 5-1, while the driven disc 5-3 must stably press against the axle. The anti-slip structure prevents slippage caused by a smooth axle surface or oil contamination during processing, ensuring that the rotational power of the drive disc 5-1 is accurately transmitted to the axle.

[0037] In practical use: Place the car axle between the uprights 4, activate the second cylinder 5-6 of the workpiece drive assembly 5 to raise the lifting seat 5-5 along the column 5-4, causing the cross support roller 5-7 to lift the axle from the bottom. Control the extension cylinder 5-2 of the other upright 4 to extend, pushing the driven plate 5-3 towards the drive plate 5-1, cooperating with the drive plate 5-1 to clamp the axle from both ends, with anti-slip contact surfaces preventing the axle from slipping. Activate the horizontal linear drive of the clamping and cleaning assembly 6, driving the moving seat 6-2 to approach the axle along the transverse cavity 6-1, with the side clamping roller 6-9 conforming to the axle from the side, the leak-proof wrapping sleeve 6-8 wrapping the collection cylinder 6-3, and the scraper 6-10 aligning with the axle processing area. Activate the electric drive of the drive plate 5-1, causing the axle, driven plate 5-3, and cross support roller 5-7 to rotate synchronously. The tool holder 3 adjusts the tool position through horizontal and vertical linear drives to cut the axle. The waste chips generated during cutting are guided by the scraper plate 6-10 and enter the collection cylinder 6-3 through the collection port 6-4. The auger 6-7 is then pushed to rotate and discharge the waste chips through the slag discharge port 6-6. After processing is completed, the drive disc 5-1 is stopped, the telescopic cylinder 5-2 retracts to release the axle, and the finished product can be taken out. The entire process achieves stable axle clamping, precise cutting, and automatic waste chip removal.
