Description

Technical Field

[0001] This invention relates to the field of automotive wheel and axle turning technology, specifically to a wheel and axle turning machine tool and a method for turning automotive wheels and axles. Background Technology

[0002] A wheel and axle refers to a machine consisting of a wheel and an axle forming a cross-shaped transmission structure that can rotate around a common axis. During wheel and axle machining, the wheel and axle blank needs to undergo chamfering, threading, and boring processes on a machine tool. Existing wheel and axle machining methods present the following problems:

[0003] Operators must manually move the axle between the machine tool spindle and tailstock, and perform axial positioning and coaxial calibration. Frequent handling and calibration lead to low production efficiency and high labor intensity. Furthermore, the accuracy of manual positioning is easily affected by operator experience. When processing axles in the same batch, the loading process must be repeated after each piece is completed. There is a lack of a continuous supply mechanism for batch workpieces, making it difficult to achieve efficient continuous processing. Existing automated loading solutions (such as robotic arm gripping) can reduce manual intervention, but they require complex sensing systems and high-precision motion mechanisms, which significantly increases equipment costs. Moreover, due to the rounded edge characteristics of the axle, it is difficult to pick up the axle by a robotic arm when storing it. The method of letting the axle roll due to its characteristics is also prone to losing control due to its own weight in the inclined channel, causing multiple workpieces to slip or collide and get stuck at the same time, making it difficult to pick up and release individual axles. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a wheel and axle turning machine tool and a method for turning automotive wheel and axles. It offers advantages such as eliminating the need for manual placement and calibration of wheel and axle between the machine frame and tailstock during machining, enabling automatic feeding of wheel and axle of the same model, and requiring only calibration of the moving table position for the first wheel and axle of the same model in a batch, thus eliminating the need for multiple calibrations during automated turning. This solves the problems of operators manually moving wheel and axles between the machine tool spindle and tailstock for axial positioning and coaxial calibration, resulting in low production efficiency, high labor intensity, and susceptibility to operator experience affecting manual positioning accuracy. Furthermore, it addresses the issue of repeated feeding processes after each wheel and axle in a batch, lacking a continuous supply mechanism for batch workpieces and hindering efficient continuous machining.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a wheel and axle turning machine tool and a method for turning automobile wheel and axles, which has the following beneficial effects:

[0019] 1. This wheel and axle turning machine tool and automotive wheel and axle turning method involves controlling the loading slide to align the moving table with the storage channel in the storage mechanism. The moving table moves towards the storage channel and pushes the control linkage end at the bottom of the limit block, causing the control linkage end to move the limit block and release the wheel and axle restricted by the limit block. The wheel and axle roll along the storage channel and rolls to the top of the moving table. Then, the moving table is controlled to move on the loading slide so that the wheel and axle on the moving table are coaxial with the tailstock. Then, the loading slide and tailstock are controlled to move synchronously along the parallel guide rail towards the machine frame. Then, the tool post assembly is controlled normally to perform turning processing on the wheel and axle. It eliminates the need for manual placement and calibration of the wheel and axle between the machine frame and tailstock during wheel and axle turning. It achieves automatic loading of wheel and axle of the same model. Only the position of the moving table needs to be calibrated for the first wheel and axle of the same model in the batch. It achieves automated turning processing without multiple calibrations.

[0020] 2. This wheel and axle turning machine tool and automotive wheel and axle turning method uses a cross-shaped storage channel to place the wheel and axle, allowing the wheel and axle to move stably within the storage channel. Combined with a limiting movement groove at the bottom of the storage channel, and controlled by a limiting block and a control linkage end, the movement of the wheel and axle within the storage channel is controlled. This enables automated feeding in conjunction with a feeding mechanism. The Y-shaped limiting block, when storing the wheel and axle, has its positioning end extending into the storage channel to position the last wheel and axle at the outlet of the storage channel, facilitating feeding. Entering the feeding mechanism; when feeding the axles, the moving table in the feeding mechanism moves towards the storage mechanism and pushes the control linkage end at the bottom of the limit block, that is, pushes the bottom of the Y-shaped structure. At this time, the positioning end swings downward until it moves out of the storage channel. At the same time, the limit end moves upward into the storage channel. During this process, the limit end moves between the penultimate axle and the penultimate axle. The penultimate axle loses the obstruction of the positioning end and rolls down into the feeding mechanism along the storage channel, while the limit end abuts against the penultimate axle to prevent other axles in the storage channel from rolling down together.

[0021] 3. The wheel and axle turning machine tool and the automotive wheel and axle turning method use a control plate located on one side of the limit block to move within a control moving slot. This control plate, in conjunction with the control gear above it, controls the wheel and axle to be turned. When the last wheel and axle in the storage channel is being loaded, the control gear extends upwards into the storage channel to control the third-to-last wheel and axles above it. After the last wheel and axle is loaded, the control linkage end resets. At this time, the second-to-last wheel and axle enters between the limit end and the positioning end. As the control linkage end continues to reset, the control gear releases control over the third-to-last wheel and axles above it and moves downwards along the storage channel to the limit end. This prevents excessive impact on the limit block and the wheel and axles within it when the control linkage end resets after the last wheel and axle is loaded, thus avoiding excessive impact on the next wheel and axle to be loaded, which would cause it to be directly ejected from the storage channel.

[0022] 4. The wheel and axle turning machine tool and the automotive wheel and axle turning method, through the control push rod set on one side of the control linkage end, when the control linkage end is pushed by the moving table, the control linkage end drives the control push rod to push the control plate, so that the control plate drives the control teeth to move upward, and controls other wheel and axles in the storage channel. Among them, the push plate set on one side of the moving table, when loading, the moving table moves towards the storage mechanism, so that the push plate extends into the limit moving groove, and pushes the control linkage end in the limit moving groove to move, thereby causing the limit block away from the control linkage end to swing and contact the control of the last wheel and axle. At the same time, the control linkage end drives the control plate to move upward along the direction of the guide rod through the control push rod, so that the control teeth on the control plate control other wheel and axles.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-9A wheel and axle turning machine tool includes a frame 1, with a parallel guide rail 11 mounted on top of the frame 1. A tool post assembly 2, a storage mechanism 3, a loading mechanism 4, and a tailstock 5 are mounted on the parallel guide rail 11. The storage mechanism 3 is located on the opposite side of the tool post assembly 2, and the loading mechanism 4 is positioned opposite to the storage mechanism 3. The storage mechanism 3 includes a limiting block 31, a storage channel 32, and a control linkage end 33. The limiting block 31 is slidably disposed at the bottom of the inner cavity of the storage channel 32, and the control linkage end 33 is located at the bottom of the limiting block 31. The loading mechanism 4 includes a loading slide 41, a moving table 42, and a carrier. The loading platform 41 is slidably mounted on the parallel guide rail 11, and the moving platform 42 is slidably mounted on the loading platform 41. The loading platform 43 is located above the moving platform 42 in the middle, and one side of the moving platform 42 is positioned opposite the control linkage terminal 33. The moving platform 42 moves towards the storage mechanism 3, and pushes the control linkage terminal 33. The control linkage terminal 33 drives the limiting block 31 to move at the bottom of the storage channel 32, and the wheel axle located at the bottom of the storage channel 32 separates from the limiting block 31. The tail seat 5 is located at the tail of the parallel guide rail 11.

[0035] In practical use, a CNC module is required to control the operation of the machine tool, and the CNC module is implemented using existing automated programming.

[0036] In use, first place the axle to be processed in the storage channel 32 of the storage mechanism 3. Take one axle and place it in the lifting platform 431 on the moving platform 42, and align the axle with the tailstock 5. Then, control the loading slide 41 to move the moving platform 42 to align with the storage channel 32 in the storage mechanism 3. The moving platform 42 moves towards the storage channel 32 and pushes the control linkage end 33 at the bottom of the limiting block 31, so that the control linkage end 33 moves the limiting block 31 and releases the axle restricted by the limiting block 31. The axle rolls along the storage channel 32 and rolls to the moving platform. Above 42, control the moving table 42 to move on the loading slide 41 so that the wheel axle on the moving table 42 is coaxial with the tailstock 5. Then control the loading slide 41 and the tailstock 5 to move synchronously along the parallel guide rail 11 towards the machine frame 1. Then control the tool post assembly 2 to perform turning processing on the wheel axle normally. There is no need to manually place the wheel axle between the machine frame 1 and the tailstock 5 and perform calibration during wheel axle turning. Automatic feeding of wheel axles of the same model can be achieved. Only the position of the moving table 42 needs to be calibrated for the first wheel axle of the same model in the batch. Automated turning processing without multiple calibrations is achieved.

[0037] Furthermore, the storage channel 32 has a cross-shaped structure, with the wheel portion of the axle placed vertically within the storage channel 32 and the axle portion placed horizontally within the storage channel 32. The storage channel 32 is tilted to the side of the frame 1. A limiting movement groove 321 is provided at the bottom of the storage channel 32 where the axle is placed. The limiting block 31 and the control linkage end 33 are both located within the limiting movement groove 321. By placing the axle in the storage channel 32 with its cross-shaped structure, the axle can move stably within the storage channel 32. Combined with the limiting movement groove 321 at the bottom of the storage channel 32, the movement of the axle within the storage channel 32 can be controlled under the control of the limiting block 31 and the control linkage end 33, thereby enabling automated feeding in conjunction with the feeding mechanism 4.

[0038] Furthermore, the limiting block 31 has a Y-shaped structure. The limiting block 31 includes a positioning end 311 and a limiting end 312. The positioning end 311 is located near the feeding mechanism 4 and extends upward into the storage channel 32. The control linkage end 33 is located at the bottom of the positioning end 311 and the limiting end 312, and the positioning end 311, the limiting end 312, and the control linkage end 33 form a Y-shaped structure. Through the Y-shaped limiting block 31, when storing the axle, the positioning end 311 of the limiting block 31 extends into the storage channel 32 to position the axle at the very end, placing it at the exit of the storage channel 32. This allows the material to enter the feeding mechanism 4 during loading. When loading the axle, the moving table 42 in the feeding mechanism 4 moves towards the storage mechanism 3 and pushes the control linkage end 33 at the bottom of the limiting block 31, i.e., pushes the bottom of the Y-shaped structure. At this time, the positioning end 311 swings downward until it moves out of the storage channel 32. At the same time, the limiting end 312 moves upward into the storage channel 32. During this process, the limiting end 312 moves between the penultimate axle and the penultimate axle. The penultimate axle loses the obstruction of the positioning end 311 and rolls down into the feeding mechanism 4 along the storage channel 32, while the limiting end 312 abuts against the penultimate axle to prevent other axles in the storage channel 32 from rolling down together.

[0039] Furthermore, a control plate 34 is provided on one side of the limiting block 31, and a control movement groove 322 is provided at the bottom of the storage channel 32 where the axle is placed. The control plate 34 is located in the control movement groove 322, and control teeth 341 are provided above the control plate 34. Every two control teeth 341 correspond to the wheel part of one axle. The control plate 34 on one side of the limiting block 31 moves in the control movement groove 322, and controls the axle to be turned in conjunction with the control teeth 341 above it. When the last axle in the storage channel 32 is being loaded, the control teeth 341 extend upward into the storage channel 32 to control the third to last axle and the others above it. The wheel axle is controlled. After the last wheel axle completes its loading, the control linkage end 33 resets. At this time, the second to last wheel axle enters between the limit end 312 and the positioning end 311. As the control linkage end 33 continues to reset, the control gear 341 releases control over the third to last wheel axle and other wheel axles above it, and moves downward along the storage channel 32 to the limit end 312. This avoids excessive impact on the limit block 31 and the wheel axles inside the limit block 31 when the control linkage end 33 resets after the last wheel axle has finished loading, causing the other wheel axles to move downward along the storage channel 32 together. This would prevent the next wheel axle to be loaded from being subjected to too much impact and being directly discharged from the storage channel 32.

[0040] Furthermore, a control push rod 331 is provided on one side of the control linkage end 33. The control push rod 331 extends to the bottom of the control plate 34. The middle part of the control linkage end 33 is rotatably connected to the limiting moving groove 321. When the moving platform 42 pushes the control linkage end 33 to move, the positioning end 311 moves towards the bottom of the storage channel 32. The limiting end 312 and the control plate 34 move upward synchronously, and the control tooth 341 moves upward into the storage channel 32 before the limiting end 312. Through the control push rod 331 provided on one side of the control linkage end 33, when the control linkage end 33 is pushed by the moving platform 42, the control linkage end 33 drives the control push rod 331 to push the control plate 34, so that the control plate 34 drives the control tooth 341 to move upward, thereby controlling other wheel axles in the storage channel 32.

[0041] Furthermore, a push plate 421 is provided on the side of the moving platform 42 near the storage mechanism 3, and the other end of the control linkage end 33 is correspondingly provided with one end of the push plate 421. A guide groove is provided on the side of the control plate 34, and a guide rod 323 is provided on the side of the control movement groove 322. The control plate 34 moves along the guide rod 323. When feeding, the moving platform 42 moves towards the storage mechanism 3 via the push plate 421 on one side of the moving platform 42, so that the push plate 421 extends into the limiting movement groove 321 and pushes the control linkage end 33 in the limiting movement groove 321 to move. This causes the limiting block 31 away from the control linkage end 33 to swing and contact the control of the last wheel axle. At the same time, the control linkage end 33 drives the control plate 34 to move upward along the direction of the guide rod 323 through the control push rod 331, so that the control teeth 341 on the control plate 34 control the other wheel axles.

[0042] Furthermore, the feeding slide 41 is provided with a feeding screw 411, the moving platform 42 is slidably connected to the feeding slide 41, the feeding screw 411 is threadedly connected to the moving platform 42, the carrier 43 includes a lifting platform 431, the lifting platform 431 is disposed above the moving platform 42, the lifting platform 431 is provided with an arc-shaped groove 432 above the lifting platform 431, the arc-shaped groove 432 is used to place the wheel part of the axle, and the axle part rests on both sides above the arc-shaped groove 432, and a feed port 433 is provided on one side of the lifting platform 431. 433 corresponds to the arc groove 432; the feeding screw 411 on the feeding slide 41 is threadedly connected to the moving table 42, controlling the movement of the moving table 42 relative to the storage mechanism 3. When feeding, the feeding screw 411 drives the moving table 42 to approach the storage mechanism 3, and then the wheel axle in the storage mechanism 3 rolls into the lifting platform 431 on the carrier seat 43. The wheel axle enters through the feed port 433 on one side of the lifting platform 431 until it contacts the arc groove 432 and stays in the arc groove 432. Then it is transferred to the space between the frame 1 and the tailstock 5 by the feeding slide 41.

[0043] Furthermore, the tool post assembly 2 includes a tool post slide 21, a four-position tool post turret 22, and a tool holder nut 23; the bottom of the tool post slide 21 is slidably disposed on the parallel guide rail 11, the four-position tool post turret 22 is slidably mounted on the tool post slide 21, and the tool holder nut 23 is located on the four-position tool post turret 22; the tool post slide 21 in the tool post assembly 2 drives the four-position tool post turret 22 to move and position, and after the turning tool is mounted on the four-position tool post turret 22 through the tool holder nut 23, the turning tool is controlled to perform turning processing on the wheel shaft.

[0044] Furthermore, a spindle box 6 is provided on the frame 1, and a three-jaw chuck 61 is provided on the end face of the spindle box 6. An installation sleeve 51 is provided on the tailstock 5. The three-jaw chuck 61 and the installation sleeve 51 are coaxially arranged. The spindle box 6 on the frame 1 and the three-jaw chuck 61 on the end face of the spindle box 6 cooperate with the installation sleeve 51 on the tailstock 5 to fix the wheel axle. Then, the spindle box 6 drives the three-jaw chuck 61 and the wheel axle to rotate relative to the turning tool to realize the turning process. The storage mechanism 3 is arranged on the opposite side of the tool post assembly 2. After the wheel axle is installed with the installation sleeve 51 and the three-jaw chuck 61, the loading slide 41 moves with the moving stage 42 to the space at the bottom of the three-jaw chuck 61. At the same time, the load seat 43 moves to the other side away from the storage mechanism 3, which will not affect the movement of the tool post slide 21.
