Description

Technical Field

[0001] The present invention relates to the technical field of turning equipment for machining axle housings of vehicles, and in particular to a turning device for machining axle housings of vehicles and a method for using the same. Background Art

[0002] The axle housing is a crucial component of an automotive drive axle. It serves as the assembly base for the final drive, differential, axle shafts, and wheels. Its primary function is to support and protect these components. Drive axle housings can be structurally categorized into three types: integral, separable, and modular. Separable and modular axle housings are difficult to assemble, adjust, and maintain, and their rigidity and strength are limited by their structure, making them unsuitable for use in large vehicles. Therefore, integral axle housings are preferred for these applications. The production process for integral axle housings requires prefabrication of molds, pouring molten steel into the mold, and then demolding the mold after cooling. The demolded semi-finished product undergoes refined processing to produce the final, integral axle housing. Because the axle shaft sleeves in the semi-finished axle housing are solid-cast, they require lathe turning for subsequent processing.

[0003] In order to ensure the accuracy of the bridge housing and prevent deviation when turning the half-axle sleeve, the bridge housing needs to be fixed. However, in the process of turning the bridge housing, the turning device in the existing technology will generate a large centrifugal force during the rotation of the bridge housing due to the irregular shape of the bridge housing. Therefore, the bridge housing is prone to shaking during the rotation. Based on the existing technology, the turning device can be appropriately improved. Summary of the Invention

[0009] Furthermore, the locking mechanism also includes several telescopic springs fixedly connected to the side of the one-way rack 1 away from the movable base, the end of the telescopic spring away from the one-way rack 1 is fixedly connected to the inner wall of the fastening movable block, and the side wall of the movable base is fixedly connected with several one-way racks 2, and the one-way rack 1 is meshed with the one-way rack 2.

[0010] Furthermore, a rotation fixing mechanism is provided at one end of the rotating shaft away from the spindle box, and the rotation fixing mechanism includes a fixed head fixedly connected to the one end of the rotating shaft away from the spindle box, and a plurality of clamping blocks are slidably connected to the one end of the fixed head away from the rotating shaft.

[0011] Furthermore, the rotating fixing mechanism also includes a sliding plate slidably connected to the inside of the fixed head, the sliding plate is fixedly connected to a return spring on the side away from the clamping block, the edge of the sliding plate is rotatably connected to several linkage rods, and the end of the linkage rod away from the sliding plate is rotatably connected to the clamping block.

[0012] Furthermore, a yielding mechanism is provided inside the support frame, which includes a rotating rod rotatably connected to the support frame, a plurality of threaded grooves 1 being provided on the rotating rod, a plurality of yielding sliding blocks being slidably connected inside the slide rail groove, the yielding sliding block being rotatably connected to the threaded groove 1 on the rotating rod, a plurality of linkage rods 2 being rotatably connected to one side of the yielding sliding block, an end of the linkage rod 2 being rotatably connected to the supporting arc plate at a distance from the yielding sliding block, a threaded groove 2 being provided at an end of the rotating rod close to the fastening moving block, and the fastening moving block being rotatably connected to the threaded groove 2.

[0013] Furthermore, a cleaning mechanism is provided inside the supporting arc plate, and a plurality of sliding grooves are provided on the supporting arc plate. A plurality of cleaning pieces are slidably connected inside the sliding grooves. A groove is provided on the top of the cleaning piece. Both ends of the cleaning piece are rotatably connected to a linkage rod three, and the end of the linkage rod three away from the cleaning piece is rotatably connected to the support frame.

[0014] A method for using a turning device for machining a vehicle axle housing includes the following steps:

[0015] S1: Initial fixation: Push the handle on the movable base and push the movable base along the fastening movable block toward one end of the axle housing. The ejector pin inside the movable base moves toward one end of the axle housing and squeezes against it. At this time, the other end of the axle housing moves toward the inside of the fixed head. The provision of the supporting arc plate facilitates the initial positioning of the axle housing and facilitates the rapid fixing of both ends of the axle housing to the device.

[0016] S2: Auxiliary locking. When the movable base is pushed, the one-way rack 2 on the movable base is squeezed against the one-way rack 1 inside the fastening movable block. The squeezed one-way rack 1 will squeeze the telescopic spring along the sliding rod. At this time, the movable base on the one-way rack 2 can move unidirectionally toward the end close to the axle housing. When the one-way rack 2 slides toward the end away from the axle housing, the one-way rack 1 will lock the one-way rack 2.

[0017] S3: Rotationally fixed, the other end of the axle housing is pressed against the sliding piece inside the fixed head. The sliding piece moves inside the fixed head and presses the return spring. At this time, the sliding piece drives the clamping block at one end of the linkage rod to move toward the outer wall of one end of the axle housing. Several clamping blocks are pressed against the outer wall of one end of the axle housing.

[0018] S4: Machining clearance. After initially fixing both ends of the axle housing, rotate the rotary handle on one side of the support leg. At this time, the rotation of the rotary rod drives the clearance sliding block to slide along the thread groove 1. The sliding of the thread groove 1 drives the support arc plate at one end of the linkage rod 2 to move downward. At this time, the support arc plate is separated from the axle housing. This setting is conducive to expanding the processing range of the turning tool;

[0019] S5: Clean the iron chips. When the linkage rod 2 drives the supporting arc plate to descend, the linkage rod 3 drives the cleaning piece at one end to move along the sliding groove to the middle of the supporting arc plate. When the processing is completed, the linkage rod 2 drives the supporting arc plate to move upward, and the linkage rod 3 drives the cleaning piece to move along the sliding groove to the two ends of the supporting arc plate. This arrangement is conducive to the cleaning piece to discharge the iron chips inside the supporting arc plate.

[0020] The present invention has the following beneficial effects:

[0021] (1) According to the present invention, when the turning device is used, it needs to be used in conjunction with a turning tool. The turning tool is slidably installed above the support frame, and the bridge shell to be turned is placed on the support arc plate. The handle on the movable base is pushed to push the movable base along the fastening movable block toward one end of the bridge shell. The ejector pin inside the movable base moves toward one end of the bridge shell and is squeezed against one end of the bridge shell. At this time, the other end of the bridge shell moves toward the inside of the fixed head. The provision of the support arc plate is beneficial for the initial positioning of the bridge shell and is beneficial for quickly fixing the two ends of the bridge shell on the device. By providing a rotating fixing mechanism, when the handle on the movable base is pushed to push the movable base along the fastening movable block toward one end of the bridge shell, the other end of the bridge shell is squeezed against the sliding plate inside the fixed head. The sliding plate moves inside the fixed head and squeezes the reset spring. At this time, the sliding plate drives the clamping block at one end of the linkage rod to move toward the outer wall near one end of the bridge shell. Several clamping blocks are squeezed against the outer wall of one end of the bridge shell. Such a provision is beneficial for fixing one end of the bridge shell and enables the bridge shell inside the fixed head to rotate with the rotating shaft.

[0022] (2) The present invention sets a locking mechanism. When the movable base is pushed, the one-way rack 2 on the movable base is squeezed against the one-way rack 1 inside the fastening movable block. The one-way rack 1 is squeezed and the telescopic spring is squeezed along the sliding rod. At this time, the movable base on the one-way rack 2 can move unidirectionally toward the end close to the bridge housing. When the one-way rack 2 slides toward the end away from the bridge housing, the one-way rack 1 locks the one-way rack 2. This setting is helpful to prevent the movable base on the one-way rack 2 from sliding outward during the processing of the bridge housing, thereby affecting the fixing effect of the two ends of the bridge housing.

[0023] (3) The present invention sets a yielding mechanism. After the two ends of the bridge housing are initially fixed, the rotating handle on one side of the support leg is rotated. At this time, the rotating rod rotates to drive the yielding sliding block to slide along the thread groove 1. The sliding of the thread groove 1 drives the supporting arc plate at one end of the linkage rod 2 to move downward, and the supporting arc plate is separated from the bridge housing. This arrangement is conducive to expanding the processing range of the turning tool. At the same time, the rotating rod rotates to drive the fastening moving block to slide along the slide groove toward one end of the bridge housing. At this time, the one-way rack 1 on the fastening moving block drives the moving base on the one-way rack 2 to move further toward one end of the bridge housing. At this time, the ejector pin is squeezed and squeezes the extrusion spring along the inside of the moving base. At this time, the elastic force of the extrusion spring increases, thereby increasing the reaction force applied to the ejector pin. This arrangement is conducive to further fixing the bridge housing at one end of the ejector pin and preventing the bridge housing from shaking during rotation.

[0024] (4) The present invention sets a cleaning mechanism. When the turning tool turns the bridge shell directly above the supporting arc plate, the iron chips that fall down will fall on the supporting arc plate. Therefore, when the linkage rod 2 drives the supporting arc plate to descend, the linkage rod 3 drives the cleaning piece at one end to move along the sliding groove toward the middle of the supporting arc plate. When the processing is completed, the linkage rod 2 drives the supporting arc plate to move upward, and the linkage rod 3 drives the cleaning piece to move along the sliding groove toward the two ends of the supporting arc plate. This arrangement is conducive to the cleaning piece to discharge the iron chips inside the supporting arc plate. In addition, a groove is opened directly above the linkage rod 3, and the two ends of the bridge shell can just fit into the groove. This arrangement further positions the bridge shell on a straight line, thereby facilitating the processing of the bridge shell.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1, please refer to Figures 1-8 As shown, the present invention is a turning device for machining a vehicle axle housing and a method for using the same, comprising a support frame 11 fixedly connected to the side wall of a spindle box 1, a rotating shaft 12 rotatably connected to the side wall of the spindle box 1, a support leg 13 fixedly connected to one end of the support frame 11 away from the spindle box 1, a support arc plate 14 provided directly above the support frame 11, and an axle housing 15 provided directly above the support arc plate 14, and further comprising:

[0040] The preliminary fixing mechanism 2 includes a preliminary fixing mechanism 2 arranged at one end of the support frame 11 away from the spindle box 1. A plurality of slide rail grooves 201 are provided inside the support frame 11. A fastening moving block 202 is slidably connected to the end of the slide rail groove 201 away from the spindle box 1.

An extrusion spring 205 is provided inside the moving base 203. The function of this component is to cooperate with the turning tool when using the turning device. The turning tool is slidably installed just above the support frame 11, and then the bridge housing 15 to be turned is placed on the supporting arc plate 14, and the handle on the movable base 203 is pushed to push the movable base 203 along the fastening movable block 202 toward one end close to the bridge housing 15. The ejector pin 204 inside the movable base 203 moves toward one end of the bridge housing 15 and is squeezed with one end of the bridge housing 15. At this time, the other end of the bridge housing 15 moves toward the inside of the fixed head 401. By setting the supporting arc plate 14, it is beneficial to the initial positioning of the bridge housing 15 and to quickly fix the two ends of the bridge housing 15 on the device.

[0041] A locking mechanism 3 is provided inside the fastening moving block 202. The locking mechanism 3 includes a plurality of sliding rods 301 slidably connected to the inside of the fastening moving block 202. One end of the sliding rod 301 close to the moving base 203 is fixedly connected to a one-way rack 302.

[0042] The locking mechanism 3 also includes a plurality of telescopic springs 303 fixedly connected to the side of the one-way rack 1 302 away from the movable base 203. One end of the telescopic spring 303 away from the one-way rack 1 302 is fixedly connected to the inner wall of the fastening movable block 202. The side wall of the movable base 203 is fixedly connected to a plurality of one-way racks 2 304. The one-way rack 1 302 is meshed with the one-way rack 2 304. The function of this component is to set the locking mechanism 3. When the movable base 203 is pushed, the one-way rack 2 304 on the movable base 203 is engaged with the fastening movable block 20 2, the one-way rack 1 302 inside is squeezed, and the one-way rack 1 302 is squeezed along the sliding rod 301 to press the telescopic spring 303. At this time, the movable base 203 on the one-way rack 2 304 can move unidirectionally toward the end close to the axle housing 15. When the one-way rack 2 304 slides toward the end away from the axle housing 15, the one-way rack 1 302 locks the one-way rack 2 304. This arrangement is beneficial to prevent the movable base 203 on the one-way rack 2 304 from sliding outward during the processing of the axle housing 15, thereby affecting the fixing effect of the two ends of the axle housing 15.

[0043] A rotating fixing mechanism 4 is provided at the end of the rotating shaft 12 away from the spindle box 1. The rotating fixing mechanism 4 includes a fixing head 401 fixedly connected to the end of the rotating shaft 12 away from the spindle box 1. The end of the fixing head 401 away from the rotating shaft 12 is slidably connected to a plurality of clamping blocks 402.

[0044] The rotating fixing mechanism 4 also includes a sliding piece 403 slidably connected to the inside of the fixed head 401. The side of the sliding piece 403 away from the clamping block 402 is fixedly connected to a return spring 404. The edge of the sliding piece 403 is rotatably connected to a plurality of linkage rods 405. The end of the linkage rod 405 away from the sliding piece 403 is rotatably connected to the clamping block 402. The function of this component is to set the rotating fixing mechanism 4. When the handle on the mobile base 203 is pushed, the mobile base 203 is moved along the fastening mobile block 202 to approach the bridge housing 1. 5, the other end of the axle housing 15 is pressed against the sliding piece 403 inside the fixed head 401. The sliding piece 403 moves inside the fixed head 401 and presses the return spring 404. At this time, the sliding piece 403 drives the clamping block 402 at one end of the linkage rod 405 to move toward the outer wall near one end of the axle housing 15. Several clamping blocks 402 are pressed against the outer wall of one end of the axle housing 15. This arrangement is conducive to fixing one end of the axle housing 15 and at the same time enables the axle housing 15 inside the fixed head 401 to rotate along with the rotating shaft 12.

[0045] Example 2 is distinguished from Example 1 in that: Figures 1-9As shown, the support frame 11 is internally provided with a yielding mechanism 5, which includes a rotating rod 501 rotatably connected to the support frame 11, and a plurality of threaded grooves 502 are provided on the rotating rod 501, and a plurality of yielding sliding blocks 503 are slidably connected inside the slide rail groove 201, and the yielding sliding block 503 is rotatably connected to the threaded groove 502 on the rotating rod 501, and one side of the yielding sliding block 503 is rotatably connected to a plurality of linkage rods 2 504, and the end of the linkage rod 2 504 away from the yielding sliding block 503 is rotatably connected to the support arc plate 14, and a threaded groove 2 505 is provided on the end of the rotating rod 501 close to the fastening moving block 202, and the fastening moving block 202 is rotatably connected to the threaded groove 2 505. The function of this component is to provide the yielding mechanism 5, and after preliminarily fixing the two ends of the bridge housing 15, the rotating handle on one side of the support leg 13 is rotated, and at this time, the rotating rod 501 rotates to drive the yielding sliding block 503 to rotate. The sliding block 503 slides along the thread groove 1 502, and the thread groove 1 502 slides to drive the supporting arc plate 14 at one end of the linkage rod 2 504 to move downward. At this time, the supporting arc plate 14 is separated from the bridge housing 15. This arrangement is conducive to expanding the processing range of the turning tool. At the same time, the rotating rod 501 rotates to drive the fastening moving block 202 to slide along the slide groove 201 toward one end close to the bridge housing 15. At this time, the one-way rack 1 302 on the fastening moving block 202 drives the moving base 203 on the one-way rack 2 304 to move further toward one end close to the bridge housing 15. At this time, the ejector pin 204 is squeezed and will squeeze the extrusion spring 205 along the inside of the moving base 203. At this time, the elastic force of the extrusion spring 205 increases, thereby increasing the reaction force given to the ejector pin 204. This arrangement is conducive to further fixing the bridge housing 15 at one end of the ejector pin 204 to prevent the bridge housing 15 from shaking during the rotation process.

[0046] The interior of the support arc plate 14 is provided with a cleaning mechanism 6, and a plurality of sliding grooves 601 are provided on the support arc plate 14. The interior of the sliding groove 601 is slidably connected with a plurality of cleaning pieces 602. A groove is provided on the top of the cleaning piece 602.

The function of this component is to set the cleaning mechanism 6. When the turning tool turns the bridge housing 15 directly above the support arc plate 14, the iron chips that fall down will fall on the support arc plate 14. Therefore, when the linkage rod 2 504 drives the support When the arc plate 14 descends, the linkage rod three 603 drives the cleaning piece 602 at one end to move along the sliding groove 601 toward the middle of the supporting arc plate 14. When the processing is completed, the linkage rod two 504 drives the supporting arc plate 14 to move upward, and the linkage rod three 603 drives the cleaning piece 602 to move along the sliding groove 601 toward the two ends of the supporting arc plate 14. This arrangement is conducive to the cleaning piece 602 to discharge the iron filings inside the supporting arc plate 14. In addition, a groove is provided directly above the linkage rod three 603, and the two ends of the bridge housing 15 can just fit into the groove. This arrangement further positions the bridge housing 15 on a straight line, thereby facilitating the processing of the bridge housing 15.

[0047] A method for using a turning device for machining a vehicle axle housing includes the following steps:

[0048] S1: Initial fixation: Push the handle on the movable base 203 and push the movable base 203 along the fastening movable block 202 toward one end of the axle housing 15. The ejector pin 204 inside the movable base 203 moves toward one end of the axle housing 15 and presses against one end of the axle housing 15.

The provision of the supporting arc plate 14 facilitates the initial positioning of the axle housing 15 and facilitates the rapid fixation of both ends of the axle housing 15 to the device.

[0049] S2: Auxiliary locking. When the movable base 203 is pushed, the one-way rack 2 304 on the movable base 203 is squeezed against the one-way rack 1 302 inside the fastening movable block 202. The one-way rack 1 302 is squeezed and presses the telescopic spring 303 along the sliding rod 301. At this time, the movable base 203 on the one-way rack 2 304 can move unidirectionally toward the end close to the axle housing 15. When the one-way rack 2 304 slides toward the end away from the axle housing 15, the one-way rack 1 302 locks the one-way rack 2 304.

[0050] S3: Rotationally fixed, the other end of the axle housing 15 is pressed against the sliding piece 403 inside the fixed head 401. The sliding piece 403 moves inside the fixed head 401 and presses the return spring 404. At this time, the sliding piece 403 drives the clamping block 402 at one end of the linkage rod 405 to move toward the outer wall of one end of the axle housing 15. Several clamping blocks 402 are pressed against the outer wall of one end of the axle housing 15.

[0051] S4: Machining and making way. After initially fixing both ends of the axle housing 15, rotate the rotary handle on one side of the support leg 13. At this time, the rotating rod 501 rotates and drives the making way sliding block 503 to slide along the thread groove 1 502. The sliding of the thread groove 1 502 drives the supporting arc plate 14 at one end of the linkage rod 2 504 to move downward. At this time, the supporting arc plate 14 is separated from the axle housing 15. This arrangement is conducive to expanding the processing range of the turning tool.

[0052] S5: Cleaning iron filings. When the linkage rod 2 504 drives the supporting arc plate 14 to descend, the linkage rod 3 603 drives the cleaning piece 602 at one end to move along the sliding groove 601 toward the middle of the supporting arc plate 14. When the processing is completed, the linkage rod 2 504 drives the supporting arc plate 14 to move upward, and the linkage rod 3 603 drives the cleaning piece 602 to move along the sliding groove 601 toward the two ends of the supporting arc plate 14. This arrangement is conducive to the cleaning piece 602 to discharge the iron filings inside the supporting arc plate 14.

[0053] A specific application of this embodiment is:

[0054] When using the turning device, it is necessary to use it in conjunction with the turning tool. The turning tool is slidably installed just above the support frame 11, and then the bridge housing 15 to be turned is placed on the supporting arc plate 14. The handle on the movable base 203 is pushed, and the movable base 203 is pushed along the fastening movable block 202 toward one end of the bridge housing 15. The ejector pin 204 inside the movable base 203 moves toward one end of the bridge housing 15 and is squeezed against one end of the bridge housing 15. At this time, the other end of the bridge housing 15 moves toward the inside of the fixed head 401. , by setting the supporting arc plate 14, it is convenient for the bridge housing 15 to be initially positioned, and it is convenient for the two ends of the bridge housing 15 to be quickly fixed on the device; by setting the locking mechanism 3, when the movable base 203 is pushed, the one-way rack 2 304 on the movable base 203 is squeezed with the one-way rack 1 302 inside the fastening movable block 202, and the one-way rack 1 302 is squeezed and squeezes the telescopic spring 303 along the sliding rod 301. At this time, the movable base 203 on the one-way rack 2 304 can be moved closer to the bridge housing 15 One end of the bridge housing 15 moves unidirectionally, and when the one-way rack 2 304 slides toward the end away from the bridge housing 15, the one-way rack 1 302 locks the one-way rack 2 304. This arrangement is beneficial to preventing the movable base 203 on the one-way rack 2 304 from sliding outward during the processing of the bridge housing 15, thereby affecting the fixing effect of the two ends of the bridge housing 15; by setting a rotating fixing mechanism 4, when the handle on the movable base 203 is pushed, the movable base 203 is pushed along the fastening moving block 202 toward the end close to the bridge housing 15 The other end of the axle housing 15 is pressed against the sliding piece 403 inside the fixed head 401. The sliding piece 403 moves inside the fixed head 401 and presses the return spring 404. At this time, the sliding piece 403 drives the clamping block 402 at one end of the linkage rod 405 to move toward the outer wall near one end of the axle housing 15. Several clamping blocks 402 are pressed against the outer wall of one end of the axle housing 15. This arrangement is conducive to fixing one end of the axle housing 15, while allowing the axle housing 15 inside the fixed head 401 to rotate along with the rotating shaft 12.

[0055] By setting the yield mechanism 5, after the two ends of the bridge housing 15 are initially fixed, the rotating handle on one side of the support leg 13 is rotated. At this time, the rotating rod 501 rotates to drive the yield sliding block 503 to slide along the thread groove 1 502, and the thread groove 1 502 slides to drive the supporting arc plate 14 at one end of the linkage rod 2 504 to move downward. At this time, the supporting arc plate 14 is separated from the bridge housing 15. This arrangement is conducive to expanding the processing range of the turning tool. At the same time, the rotating rod 501 rotates to drive the fastening moving block 202 to slide along the slide groove 201 toward one end close to the bridge housing 15. At this time, the one-way rack 1 302 on the fastening moving block 202 drives the moving base 203 on the one-way rack 2 304 to move further toward the end of the bridge housing 15. At this time, the ejector pin 204 is squeezed and will squeeze the extrusion spring 205 along the inside of the moving base 203. At this time, the elastic force of the extrusion spring 205 increases, thereby increasing the reaction force given to the ejector pin 204. This arrangement is conducive to further fixing The bridge housing 15 at one end of the fixed ejector pin 204 prevents the bridge housing 15 from shaking during the rotation process; by setting the cleaning mechanism 6, when the turning tool turns the bridge housing 15 directly above the support arc plate 14, the fallen iron chips will fall on the support arc plate 14. Therefore, when the linkage rod 2 504 drives the support arc plate 14 to descend, the linkage rod 3 603 drives the cleaning piece 602 at one end to move along the sliding groove 601 toward the middle of the support arc plate 14. When the processing is completed, the linkage rod 2 504 drives the support arc plate 14 to move upward, and the linkage rod 3 603 drives the cleaning piece 602 to move along the sliding groove 601 toward the two ends of the support arc plate 14. This arrangement is conducive to the cleaning piece 602 to discharge the iron chips inside the support arc plate 14. In addition, a groove is provided directly above the linkage rod 3 603, and the two ends of the bridge housing 15 can just fit into the groove. This arrangement further positions the bridge housing 15 on a straight line, thereby facilitating the processing of the bridge housing 15.
