Description

Technical Field

[0001] The present invention relates to the technical field of ball cage processing, and in particular to a ball cage end face and inner hole processing device. Background Art

[0002] The ball joint is a key component in the vehicle's transmission system. It is typically used in front-wheel drive or four-wheel drive vehicles, allowing the wheels to turn while still transmitting power and maintaining a constant speed.

[0003] Depending on the required mechanical properties, the ball cage blank is usually manufactured by forging or casting. Since the ball cage is a high-precision equipment, it needs to be processed by a CNC lathe. Milling of the end face and inner hole of the ball cage blank is a necessary step in the processing of the ball cage blank.

[0004] When the existing CNC machine tool processes the end face and inner hole of the ball cage blank in large quantities, the unprocessed ball cage blank is first placed in the special fixture of the center frame and fixed by the hydraulic cylinder. The left and right sides of the CNC machine tool are respectively equipped with special servo system power heads. The top of the left power head is equipped with a special milling cutter for the inner diameter of the ball cage, and the top of the right power head is equipped with a special milling cutter for the end face. The two servo system power heads are started at the same time. The two servo system power heads respectively drive the special milling cutter for the inner diameter and the special milling cutter for the end face to process the inner hole and end face of the ball cage blank. After the processing is completed, the machine tool is unloaded. The machined ball cage blank is clamped and a new unmachined ball cage blank is re-clamped to repeat the cycle. However, each time the ball cage blank is processed, the fixture needs to release the clamping limit of the processed ball cage blank, and the operator removes it from the fixture, and then installs the unmachined ball cage blank into the fixture for clamping. The removal and installation of the ball cage blank are carried out in sequence, resulting in the cumbersome and time-consuming steps of replacing the ball cage blank, which not only reduces the efficiency of replacing the ball cage blank, but also increases the time required to complete the processing of a large number of ball cage blanks.

DETAILED DESCRIPTION

[0037] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] See Figure 1 and Figure 2 A ball cage end face and inner hole processing device includes a processing machine tool 1, in which a processing module 10, a processing module 2 11 and a lifting module 12 are provided.

[0039] During specific operation, the processing module 10 is the existing ball cage inner hole milling processing structure, the processing module 2 11 is the existing ball cage end face milling processing structure, and the lifting module 12 is the existing lifting structure.

[0040] See Figure 2-Figure 4 The ball cage end face and inner hole processing device also includes a positioning mechanism 2, which is connected to the lifting module 12 by welding. The clamping mechanism 3 includes a cylindrical shell 20 fixedly connected to the lifting module 12 through a connecting seat. A material replacement opening 21 is provided at one end of the cylindrical shell 20 away from the connecting seat. Processing through holes 26 are provided on both side walls of the cylindrical shell 20 near the connecting seat. A rotating shaft 22 is passed through the middle of the cylindrical shell 20 and is rotatably connected to it through a bearing.

[0041] See Figure 2 、 Figure 5 and Figure 7The ball cage end face and inner hole processing device also includes a clamping mechanism 3, which is connected to the cylindrical shell 20. The clamping mechanism 3 includes a material changing disk 30 mounted on the rotating shaft 22. The material changing disk 30 is provided with a plurality of circumferentially evenly distributed discharge holes 31 for placing the ball cage blank. The discharge holes 31 are in the shape of a stepped cylinder with a larger aperture on the left and a smaller aperture on the right.

[0042] During the specific operation, the stepped cylindrical shape of the discharge hole 31 is consistent with the ball cage blank to be processed (such as Figure 9 The shape of the ball cage blank is consistent with that shown in the figure. In the initial state, there is a discharge hole 31 located at the material change opening 21, and two processing holes 26 are coaxial with the discharge hole 31 at the processing position. The two processing holes 26 are used for feeding the processing module 1 10 and the processing module 2 11 when processing the ball cage blank. When processing multiple ball cage blanks, the ball cage blanks can be manually placed in the discharge hole 31 at the material change opening 21. The rotatable material change disk 30 can drive multiple unprocessed ball cage blanks to the processing position in turn through the multiple discharge holes 31, and at the same time drive the processed ball cage blanks to the material change position.

[0043] See Figure 2 The ball cage end face and inner hole processing device also includes a pushing mechanism 4, which is connected to the processing machine tool 1 and is used for installing and removing the ball cage blank at the material replacement position.

[0044] See Figure 2 、 Figure 3 、 Figure 6 and Figure 7 The pushing mechanism 4 includes a limiting tube 40 installed in the processing machine tool 1, and the right end of the limiting tube 40 is slidably connected to a moving rod 41, the moving rod 41 is a horizontal T-shaped cylindrical structure and the vertical section of the moving rod 41 is located in the limiting tube 40, and a guide plate 42 is installed at the right end of the moving rod 41, and a placing head 43 is installed at the right end of the guide plate 42, and a pushing part 44 is connected to the guide plate 42; the pushing mechanism 4 also includes a moving plate 45 slidably sleeved on the limiting tube 40 and connected to the pushing part 44, and a driving member 2 46 is installed at the left end of the moving plate 45, and the driving member 2 46 is fixedly connected to the processing machine tool 1.

[0045] During specific operation, the pushing mechanism 4 can be detachably mounted on the mounting frame inside the processing machine tool 1. The second driving member 46 is an existing displacement driving member, such as a hydraulic push rod, an electric push rod, etc. The placing head 43 is coaxially distributed with the discharge hole 31 at the material changing opening 21. During initial operation, the placing head 43 is away from the discharge hole 31, and space is required for placing the ball cage blank. The ball cage blank to be processed is placed on the placing head 43, and then the second driving member 46 is started. The second driving member 46 drives the pushing part 44 to move through the moving plate 45, and the pushing part 44 drives the guide plate 42 to move. The guide plate 42 drives the ball cage blank on the placing head 43 to move toward the discharge hole 31, and drives the moving rod 41 to move in the limiting tube 40 until the vertical section of the moving rod 41 is in contact with the inner end of the right wall of the limiting tube 40. At this time, the right end of the placing head 43 is located at the left end of the discharge hole 31 and moves part of the ball cage blank into the discharge hole 31.

[0046] See Figure 3 、 Figure 6 and Figure 7 The pushing part 44 includes a plurality of pushing rods 440 that are evenly distributed circumferentially and installed at the right end of the movable plate 45. The right ends of the plurality of pushing rods 440 slide through the guide plate 42 and are jointly installed with a pushing ring 441. The outer circumference of the pushing rod 440 is provided with a return spring 442 whose two ends are respectively fixedly connected to the guide plate 42 and the movable plate 45.

[0047] During specific operation, the driving member 2 46 continues to move and continues to push the multiple push rods 440 through the moving plate 45. Since the vertical section of the moving rod 41 is in contact with the inner end of the right wall of the limiting tube 40, the guide plate 42 is limited. At this time, the multiple push rods 440 and the guide plate 42 are relatively displaced and the ball cage blank on the placement head 43 is pushed into the discharge hole 31 through the pushing ring 441, realizing the function of loading the ball cage blank. After that, the driving member 2 46 drives the moving plate 45 to reset, that is, the ball cage blank is transported to the corresponding discharge hole 31 and the ball cage blank is separated from the placement head 43 only through the driving member 2 46.

[0048] See Figure 6 and Figure 7 The right end of the movable plate 45 is equipped with a linkage rod 47, the right end of the linkage rod 47 is equipped with a mounting plate 48, and the left end of the mounting plate 48 is equipped with a discharge column 49.

[0049] During specific operation, when there are ball cage blanks in multiple discharge holes 31, when loading the ball cage blank again, the movable plate 45 is first driven by the driving part 2 46 to move away from the discharge hole 31, and the movable plate 45 drives the unloading column 49 to move toward the discharge hole 31 through the linkage rod 47 and the mounting plate 48, and unloads the ball cage blank processed in the discharge hole 31, and then repeats the steps of loading the unprocessed ball cage blank.

[0050] See Figure 5 and Figure 7 The left and right sides of the discharge hole 31 are respectively connected with a plurality of circumferentially distributed clamping parts 1 32 and a plurality of circumferentially distributed clamping parts 2 33, and the clamping parts 1 32 and the clamping parts 2 33 jointly clamp the ball cage blank; the structure of the clamping part 2 33 is the same as that of the clamping part 1 32, only the size is different.

[0051] See Figure 4 The positioning mechanism 2 also includes a driving member 23 installed at the outer end of the right side wall of the cylindrical shell 20 and with the output shaft fixedly connected to the rotating shaft 22. Two positioning through holes 24 are symmetrically opened up and down on the left and right side walls of the cylindrical shell 20 near the lifting module 12. Guide slopes 25 are provided on the left and right side walls of the cylindrical shell 20 at the upper end of the material changing opening 21.

[0052] See Figure 5 、 Figure 7 and Figure 8 When the cam 324 is in the unlock position, the latch 326 is in the unlock position, and the latch 326 is in the unlock position, which can effectively stop the cam 324 from sliding into the unlock position, thereby effectively stopping the cam 324 in the unlock position.

[0053] During specific operation, the driving member 23 is an existing servo motor, which can accurately control the rotation angle. After the ball cage blank is placed in the discharge hole 31, the driving member 23 is started intermittently. The driving member 23 drives the material changing plate 30 to rotate through the rotating shaft 22. The rotation angle of the material changing plate 30 matches the number of the discharge holes 31, that is, each rotation replaces the discharge holes 31 at the processing position and the material changing position. When the rotating material changing plate 30 drives the ball cage blank in the discharge hole 31 at the material changing position to rotate toward the processing position, the material changing plate 30 drives the extrusion rods 322 in the clamping part 1 32 and the extrusion rods 322 in the clamping part 2 33 to move, and the extrusion rods 32 2 and the balls thereon cooperate with the guide inclined surface 25 and are forced to move into the sliding groove 320. The slope of the moving extrusion rod 322 pushes the slope of the clamping rod 323 and at the same time the telescopic spring 326. The clamping rod 323 is forced to drive the clamping arc plate 324 to move toward the ball cage blank. When the extrusion rod 322 enters the cylindrical shell 20, the clamping arc plate 324 is in close contact with the surface of the ball cage blank. The multiple clamping arc plates 324 in the same discharge hole 31 jointly clamp the ball cage blank. The inner arc surface of the clamping arc plate 324 can be provided with anti-slip teeth or paved with anti-slip pads. The ball cage blank entering the cylindrical shell 20 is always in a clamped state, that is, it is still in a clamped state when it is rotated to the processing position.

[0054] See Figure 2 and Figure 3 The upper end of the processing module 10 is connected to a measuring module 14.

[0055] During specific operation, after the unprocessed ball cage blank is moved to the processing position, the lifting module 12 is started first. The lifting module 12 drives the ball cage blank at the processing position in the material changing tray 30 to move upward through the cylindrical shell 20 to a position where the axis and the measuring module 14 are at the same height. The measuring module 14 is an existing depth measuring instrument. Then the processing module 10 drives the measuring module 14 to feed into the inner hole of the ball cage blank and measure its depth. Then the processing module 10 drives the measuring module 14 to reset, and the lifting module 12 drives the ball cage blank at the processing position in the material changing tray 30 to reset through the cylindrical shell 20.

[0056] See Figure 5 The clamping mechanism 3 also includes a plurality of limiting holes 34 opened on the material changing tray 30 and respectively located between two adjacent material discharge holes 31. The limiting holes 34 are coaxially distributed with the left and right positioning holes 24 at the corresponding positions.

[0057] See Figure 3-Figure 5 The processing module 2 11 is provided with two limit posts 13 symmetrically mounted on the upper and lower sides, and the limit posts 13 are coaxially distributed with the positioning through holes 24 at corresponding positions.

[0058] During the specific work, after the inner hole inspection of the ball cage blank to be processed is completed, the processing module 10 and the processing module 2 11 are started at the same time, and the processing module 2 11 drives the two limit columns 13 to pass through the corresponding positioning through holes 24 and plug and match with the upper and lower limit through holes 34 to realize the function of limiting the material exchange plate 30, so as to avoid the phenomenon that the ball cage blank is subjected to excessive force during processing and drives the material exchange plate 30 to rotate. The position of the ball cage blank can also be corrected to ensure that the ball cage blank is accurately in the processing position. After that, the processing module 1 1 0 moves toward the inner hole of the ball cage blank and mills the inner hole. At the same time, the processing module 2 11 mills the end of the ball cage blank. The processing module 2 11 retreats a short distance after completing the work to ensure that the limit column 13 is always plugged into the limit through hole 34 during the processing process, and provides conditions for the processing module 10 to drive the feeding of the measuring module 14. The fed measuring module 14 enters the corresponding limit through hole 34 to avoid collision between the measuring module 14 and the cylindrical shell 20. It should be noted that the measuring module There is a certain gap between the maximum feeding distance of block 14 and the retracted limiting column 13, and the processing module 10 continues to feed and mill the depth of the inner hole of the ball cage blank. When the inner hole milling of the ball cage blank is completed, the processing module 10 and the processing module 2 11 retreat, and the limiting column 13 is separated from the limiting through hole 34. Then the driving member 1 23 drives the material changing disk 30 to rotate intermittently, thereby moving the unprocessed ball cage blank to the processing position, and moving the processed ball cage blank to the material changing position, repeating the steps of ball cage blank processing, and pushing the material at the same time. Mechanism 4 unloads the processed ball cage blank and replaces the unprocessed ball cage blank in the discharge hole 31. The loading and unloading of the ball cage blank and the processing of the ball cage blank can be carried out simultaneously, and the unprocessed ball cage blank can be moved to the processing position and the processed ball cage blank can be moved to the material replacement position through only one rotation process, which effectively reduces the steps of installing and disassembling the ball cage blank at the processing position, and effectively shortens the time for replacing two ball cage blanks at the processing position, greatly improving the efficiency of processing multiple ball cage blanks.
