Description

Technical Field

[0001] The 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 use method thereof. Background Art

[0002] The axle housing is one of the important components of the automobile drive axle. It is the assembly base for installing the main reducer, differential, half-axle and wheel. Its main function is to support and protect the main reducer, differential and half-axle. The drive axle housing can be divided into three types from the structure: integral axle housing, separable axle housing and combined axle housing. Among them, the separable axle housing and combined axle housing cannot be used in large vehicles because of the inconvenience of assembly, adjustment and maintenance. The rigidity and strength of the axle housing are limited by the structure. Therefore, an integral axle housing is required in large vehicles. The production process of the integral axle housing requires prefabrication of the mold first, and then pouring the smelted molten steel into the prefabricated mold. After the molten steel is cooled, it is demoulded, and then the semi-finished product after demoulding is finely processed to finally obtain the integral axle housing finished product. Since the half-axle sleeve in the semi-finished axle housing is solid casting, it needs to be turned by lathe in 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, during the process of turning the bridge housing, the turning device in the prior art 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 prior art, the turning device can be appropriately improved. Summary of the invention

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

[0015] S1: Initial fixation, push the handle on the mobile base, push the mobile base along the fastening moving block to one end close to the bridge housing, the ejector inside the mobile base moves toward one end of the bridge housing and squeezes against one end of the bridge housing, at this time the other end of the bridge housing moves toward the inside of the fixed head, the support arc plate is provided to facilitate the initial positioning of the bridge housing, and to facilitate the rapid fixing of the two ends of the bridge housing on the device;

[0016] S2: Auxiliary locking. When the moving base is pushed, the one-way rack 2 on the moving base is squeezed by the one-way rack 1 inside the fastening moving block. The one-way rack 1 is squeezed and the telescopic spring is squeezed along the sliding rod. At this time, the moving 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.

[0017] S3: Rotate and fix, the other end of the bridge housing is pressed against the sliding piece inside the fixed head, the sliding piece moves inside the fixed head and presses the reset spring, at this time the sliding piece drives the clamping block at one end of the linkage rod to move toward the outer wall close to one end of the bridge housing, and several clamping blocks are pressed against the outer wall of one end of the bridge housing;

[0018] S4: Machining clearance. 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 clearance 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. At this time, the supporting arc plate is separated from the bridge housing. This setting is conducive to expanding the processing range of the turning tool;

[0019] S5: Cleaning iron filings. When linkage rod 2 drives the supporting arc plate to descend, 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, linkage rod 2 drives the supporting arc plate to move upward, and linkage rod 3 drives the cleaning piece to move along the sliding groove toward both ends of the supporting arc plate. This arrangement is conducive to the cleaning piece to discharge the iron filings 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 just above the support frame, and then the bridge shell to be turned is placed on the supporting arc plate. The handle on the movable base is pushed to push the movable base along the fastening movable block toward one end close to the bridge shell. The ejector pin inside the movable base moves toward one end of the bridge shell and is pressed 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 supporting arc plate is beneficial to the initial positioning of the bridge shell and is beneficial to 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 close to the bridge shell, the other end of the bridge shell is pressed against the sliding plate inside the fixed head. The sliding plate moves inside the fixed head and presses 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 close to one end of the bridge shell. Several clamping blocks are pressed against the outer wall of one end of the bridge shell. Such a provision is beneficial to 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 with 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 beneficial 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 provides a yielding mechanism. After the two ends of the bridge shell are initially fixed, the rotating handle on one side of the supporting 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 shell. This arrangement is beneficial 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 rail groove toward one end close to the bridge shell. 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 close to the bridge shell. At this time, the ejector pin is squeezed and the extrusion spring is squeezed 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 beneficial to further fix the bridge shell at one end of the ejector pin and prevent the bridge shell 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 filings 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 sheet 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 sheet to move along the sliding groove toward the two ends of the supporting arc plate. This arrangement is conducive to the cleaning sheet to discharge the iron filings 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

The sliding block 503 slides along the thread groove 1 502, and 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 bridge housing 15. This arrangement is beneficial 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 rail 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.

When the turning tool performs turning processing on the bridge housing 15 directly above the support arc plate 14, the iron filings 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 sheet 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 sheet 602 to move along the sliding groove 601 toward the two ends of the supporting arc plate 14.

[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 sheet 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 sheet 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 sheet 602 to discharge the iron filings inside the supporting arc plate 14.

This arrangement is beneficial to prevent the movable base 203 on the one-way rack 204 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 bridge housing 15 is pressed against the sliding sheet 403 inside the fixed head 401, and the sliding sheet 403 moves inside the fixed head 401 and presses the return spring 404. At this time, the sliding sheet 403 drives the clamping block 402 at one end of the linkage rod 405 to move toward the outer wall close to one end of the bridge housing 15, and a plurality of clamping blocks 402 are pressed against the outer wall of one end of the bridge housing 15. This arrangement is conducive to fixing one end of the bridge housing 15, and at the same time enables the bridge housing 15 inside the fixed head 401 to rotate with the rotating shaft 12;

[0055] By setting the yielding mechanism 5, after the two ends of the bridge housing 15 are initially fixed, the rotating handle on one side of the supporting leg 13 is rotated. At this time, the rotating rod 501 rotates to drive the yielding sliding block 503 to slide along the thread groove 1 502, and 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 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 rail 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 squeezing spring 205 along the inside of the moving base 203. At this time, the elastic force of the squeezing 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 supporting arc plate 14, the fallen iron filings will fall on the supporting arc plate 14. Therefore, 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. 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.
