[0040] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0041] Embodiment 1

[0042] like Figure 1 As shown, a lightweight spliced ​​ball cage processing equipment for a bidirectional sliding constant velocity universal joint comprises:

[0043] A friction welding machine 1, comprising a machine tool, a spindle 11 for fixing a workpiece and driving the end workpiece to rotate, a hydraulic slide 12 for driving the rod workpiece to move horizontally, and a roller group 13 arranged on the machine tool for rotating the rod workpiece;

[0044] A pre-processing mechanism 2, wherein the pre-processing mechanism 2 is horizontally slidably connected to the machine tool perpendicular to the upsetting direction of the workpiece and is used for calibrating and pre-processing the workpiece;

[0045] A fastening mechanism 3, which is arranged on the hydraulic slide 12 and is used to fix the workpiece;

[0046] A processing mechanism 4, which is arranged on the other side of the workpiece and is used to grind the flash of the workpiece after welding;

[0047] The tracking mechanism 5 is arranged between the pre-processing mechanism 2 and the processing mechanism 4 and is used to make the pre-processing mechanism 2 and the processing mechanism 4 work according to a predetermined path.

[0048] In this embodiment, by providing the pre-processing mechanism 2, the fastening mechanism 3 and the processing mechanism 4, alignment and calibration of the workpiece before processing are achieved, and the workpiece is processed so that the workpiece can be better welded.

[0049] In detail, the two workpieces are fixed on the main shaft 11 and the slide by the fastening mechanism 3, the two ends of the workpieces are calibrated by the pre-processing mechanism 2, and the workpieces are kept fixed in cooperation with the fastening mechanism 3, and then the end faces of the workpieces are processed. After the processing is completed, the workpieces are welded, and while welding, the processing mechanism 4 assists in the welding and performs grinding after welding is completed.

[0050] It should be noted that the principle of friction welding is to butt two circular workpieces together so that one workpiece rotates at high speed with the center line as the axis, and then the other workpiece applies axial pressure to the optional workpiece. When the given friction time or the specified friction deformation amount is reached, the workpiece stops rotating and the forging pressure is applied. The joint produces a certain plastic deformation under the forging pressure, and the chuck is released after a period of time to complete the welding process. By processing the ends of the two workpieces to increase the friction coefficient of the ends, the efficiency of frictional heat generation can be improved, thereby improving the efficiency of welding;

[0051] It is worth mentioning that by providing the fastening mechanism 3, the end workpiece and the rod workpiece can be aligned with each other, thereby improving product quality, reducing the time required for manual alignment, and improving efficiency.

[0052] Further, if Figure 2 , Figure 3 As shown, the pre-processing mechanism 2 includes a calibration component 21 for aligning the end workpiece with the stem workpiece and a processing component 22 for performing pre-processing on the end workpiece and the stem workpiece.

[0053] In this embodiment, by providing the calibration component 21 and the processing component 22, the workpiece can be calibrated and aligned first, and then the surface can be processed.

[0054] It should be noted that since the end workpiece is fixed on the rotating shaft and cannot move, it is necessary to use the calibration component 21 of the pre-processing mechanism 2 to determine the position of the end workpiece and move and adjust the position of the rod workpiece to achieve alignment and calibration of the two workpieces.

[0055] It is worth mentioning that after the calibration of the workpiece is completed, the workpiece is kept fixed, and then the workpiece is processed by the processing component 22 to ensure the processing effect of the workpiece pre-processing.

[0056] Further, if Figure 2 As shown, the calibration component 21 includes a fixed frame 211 arranged on one side of the workpiece, a calibration frame 212 arranged on the fixed frame 211, four groups of sliding rods 213 arranged around the calibration frame 212 and springs arranged between the sliding rods 213 and the calibration frame 212, a stabilizing block 214 arranged in the middle of the sliding rods 213 and slidably connected to the ends of the sliding rods 213 around them, and electric clamps 215 arranged on both sides of the stabilizing block 214.

[0057] In this embodiment, the calibration frame 212, the stabilizing block 214 and the electric clamp 215 are provided to clamp the ends of the two workpieces, and the position of the rod workpiece is adjusted during the clamping process to achieve alignment of the two workpieces.

[0058] In detail, the calibration component 21 moves to the middle of the two workpieces, and the electric clamp 215 is started to clamp the ends of the two workpieces. During the clamping process, the end workpieces remain stationary, and the electric clamp 215 drives the stabilizing block 214 to move to adapt to the position of the end workpieces. The stabilizing block 214 simultaneously causes the rod workpiece to follow the movement. When the electric clamp 215 completely clamps the ends of the two workpieces, the rod workpiece is aligned with the end workpiece.

[0059] It should be noted that the end of the electric clamp 215 needs to be set to a shape that fits the surface of the workpiece to avoid the situation where the clamp is not clamped in place, resulting in misalignment.

[0060] It is worth mentioning that, through the multiple slide bars 213 provided on the calibration frame 212 , the stabilizing block 214 can move freely in the calibration frame 212 , so as to determine and adjust the position of the workpiece.

[0061] Further, if Figure 3 , Figure 4 As shown, the processing component 22 includes a processing table 221 arranged on a fixed frame 211 and fixedly connected to a stabilizing block 214, a reciprocating block 222 horizontally slidably connected to the processing table 221, a first motor driving the reciprocating block 222 to reciprocate by a gear rack transmission, two groups of turntables 223 rotatably connected to both ends of the reciprocating block 222 and driven by a gear rack transmission, and two drill bits 224 respectively fixed on the two groups of turntables 223.

[0062] In this embodiment, a turntable 223 and a drill bit 224 are provided to process the surface of the workpiece end. The drill bit 224 is used to drill a large number of small grooves on the surface of the workpiece, thereby increasing the roughness of the surface of the workpiece end and achieving rapid heat generation during welding.

[0063] In detail, after the electric clamp 215 fixes the workpiece, the first motor drives the reciprocating block 222 to move back and forth, so that the drill bits 224 at both ends contact the workpieces at both ends respectively and successively, and the drill bits 224 are used to drill small grooves on the workpieces on both sides.

[0064] It should be noted that a pair of reciprocating racks 225 are disposed on the reciprocating block 222, and an incomplete gear 226 driven by a first motor is disposed between the racks. The incomplete gear 226 is rotated to drive the rack 53 and the reciprocating block 222 to reciprocate.

[0065] In addition, a first bevel gear 227 is fixedly connected to the turntable 223, the first bevel gear 227 is meshed with the second bevel gear 228, and a ratchet gear 229 is fixedly connected to the lower end of the second bevel gear 228, the ratchet gear 229 is meshed with a steering rack 230 fixed on the processing table 221, and the turntable 223 is driven to rotate by the movement of the reciprocating block 222.

[0066] It is worth mentioning that, with the movement of the reciprocating block 222, the turntable 223 will rotate a certain angle after each drilling, so that the grooves on a single workpiece are arranged in a circular pattern.

[0067] Further, if Figure 5 , Figure 6 As shown, the fastening mechanism 3 includes a stabilizing component 31 for adjusting the position of the rod workpiece and a fixing component 32 disposed on the stabilizing component 31 and for fixing the rod workpiece.

[0068] In this embodiment, by providing a stabilizing assembly 31 and a fixing assembly 32 , stable clamping of the rod workpiece is achieved.

[0069] In detail, the rod workpiece is fixed on the stabilizing component 31 by the fixing component 32 to prevent the rod workpiece from slipping and fixing failure during processing. After the fixing is completed, the stabilizing component 31 cooperates with the calibration component 21 to adjust the position of the rod workpiece, and completes the fixing after the adjustment.

[0070] It should be noted that after the worker places the rod workpiece on the stabilizing assembly, the fixing assembly 32 automatically fixes the rod workpiece on the stabilizing assembly 31 and completes the position adjustment and fixation through the calibration assembly 21, without the need for manual fixing operations.

[0071] Further, if Figure 5 As shown, the stabilizing assembly 31 includes two groups of fixed slots 311 arranged above the slide, two groups of cross bars 312 slidably connected to the lower ends of the fixed slots 311 and fixedly connected to each other at both ends, vertical bars 313 vertically slidably connected to both ends of the cross bars 312, a fixed rod 314 for connecting the two fixed slots 311, and two groups of electromagnets 315 arranged on both sides of the fixed rod 314, and springs are arranged at both ends of the cross bars 312 and the vertical bars 313.

[0072] In this embodiment, by providing the fixing groove 311 and cooperating with the horizontal rod 312 and the vertical rod 313 , the fixing groove 311 can move freely in the plane, so that the workpiece can be adjusted and accurately aligned under the operation of the calibration component 21 .

[0073] In detail, the calibration component 21 drives the workpiece to move, and the corresponding fixed slot 311 moves synchronously, and the position adjustment is achieved based on the horizontal bar 312 and the vertical bar 313. After the position adjustment is completed, that is, the electric clamp 215 is fully clamped, the electromagnet 315 is energized, and the two electromagnets 315 attract each other to fix the fixed rod 314, so that the fixed slot 311 remains stable.

[0074] It should be noted that, in order for the electric clamp 215 to control the electromagnet 315 , a switch may be provided on the electric clamp 215 .

[0075] Further, if Figure 6 As shown, the fixing assembly 32 includes pressure blocks 321 respectively arranged on two groups of fixing grooves 311 and respectively located on both sides, a movable rod 322 hinged to the outer side of the pressure block 321 and hinged to the fixing groove 311 in the middle, a lifting rod 323 fixedly connected to the two groups of movable rods 322, a lifting rod 324 arranged below the lifting rod 323, a first threaded rod 325 rotatably connected to the machine tool and threadedly connected to the lifting rod 324, a first gear 326 fixedly connected to the lower end of the first threaded rod 325, and a first rack 327 fixedly connected to both sides of the slide and meshing with the first gear 326.

[0076] In this embodiment, the pressing block 321 and the lifting rod 324 are provided to fix the rod workpiece, and the pressing block 321 is used to fix the workpiece in the fixing groove 311 .

[0077] In detail, after the workpiece is placed in the fixing groove 311, the slide moves forward, and the first rack 327 drives the first gear 326 and the first threaded rod 325 to rotate, so that the lifting rod 324 moves upward, and the lifting rod 323 is lifted accordingly. The outer end of the movable rod 322 is lifted by the lifting rod 323, and then the movable rod 322 is rotated to press the pressure block 321 on the workpiece to fix the workpiece.

[0078] It should be noted that the separation and fixation of the pressing block 321 can be controlled by lifting the lifting rod 323 through the lifting rod 324, which can be coordinated with the movement of the fixing frame 211 to avoid affecting the fixation of the workpiece due to the movement of the fixing frame 211.

[0079] It is worth mentioning that the inner side of the pressing block 321 can be made of materials such as rubber, which can reduce the possibility of the workpiece slipping on the one hand and prevent the pressing block 321 from scratching the workpiece on the other hand.

[0080] Further, if Figure 7 As shown, the processing mechanism 4 includes an auxiliary component 41 for cooperating with the friction welding of the workpiece and a grinding component 42 for grinding after the welding is completed. The grinding component 42 includes a fixed bracket 421 arranged on one side of the workpiece, and a grinding tool 422 arranged on the fixed bracket 421 and moved by an electric cylinder.

[0081] In this embodiment, by providing the auxiliary component 41 and the grinding component 42, the welding of the workpiece is promoted on the one hand, and the welded workpiece is post-processed on the other hand.

[0082] In detail, after the workpiece pre-processing is completed, the pre-processing mechanism 2 is disengaged, and the slide drives the workpiece forward. At this time, the processing mechanism 4 approaches the workpiece, the workpiece is welded, and the auxiliary mechanism is started. After welding is completed, the grinding tool 422 is moved to the workpiece for grinding.

[0083] It should be noted that two groups of electric cylinders are provided on the fixed bracket 421 for controlling the movement of the grinding tool 422 to grind the workpiece.

[0084] Further, if Figure 7 As shown, the auxiliary component 41 includes a collecting tank 411 arranged below the drill bit 224, a transfer pipe 412 connected to the collecting tank 411, a hinged tube 413 hinged to the other end of the transfer pipe 412 and provided with an air pump for conveying metal powder, a nozzle 414 arranged on the hinged tube 413, a second gear 415 arranged on the outside of the rotating shaft of the hinged tube 413, and a second rack 416 fixedly connected to the machine tool and meshing with the second gear 415.

[0085] In this embodiment, by providing a collection tank 411 and a nozzle 414, the debris generated during the operation of the processing mechanism can be recycled and reused, and by adding metal debris to the contact surface in the middle of the workpieces, rapid heat generation between the workpieces can be further achieved.

[0086] In detail, when the processing component 22 is working, metal debris falls into the collection tank 411, reaches the articulated tube 413 through the transfer tube 412, and is transported into the nozzle 414 through the articulated tube 413. When the two workpieces are calibrated and approach each other, the processing mechanism 4 approaches the workpiece, and the second rack 416 drives the second gear 415 and the articulated tube 413 to rotate. The articulated tube 413 rotates downward and approaches the contact surface of the workpiece, and the nozzle 414 is used to spray the metal debris into the contact surface of the workpiece.

[0087] It should be noted that the lower end of the articulated tube 413 is hinged on the fixed bracket 421 and is hinged to the transfer tube 412. At the same time, the articulated tube 413 is connected to the transfer tube 412. An air pump is set at the lower end of the articulated tube 413 to blow metal debris into the nozzle 414 for storage.

[0088] It is worth mentioning that by adding debris to the friction surface of the workpiece, on the one hand, the friction coefficient of the metal is further increased to generate heat, and on the other hand, the metal debris is used to fill the grooves to reduce the occurrence of cold welds.

[0089] Further, if Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown, the tracking mechanism 5 includes a moving table 51 arranged on the machine tool and used to install the pre-processing mechanism 2 and the processing mechanism 4, a screw 52 for driving the moving table 51 to move, and multiple sets of driving racks 53 arranged on both sides of the slide. The driving racks 53 drive the screw 52 to rotate by connecting the gear racks and the transmission belt.

[0090] In this embodiment, by providing a moving table 51 and a driving rack 53, the slide table controls the moving table 51, so that various operations of the pre-processing mechanism 2 and the processing mechanism 4 are performed according to the movement of the slide table.

[0091] In detail, when the workpiece is prevented from being clamped on the fastening mechanism 3, the slide moves forward. At this time, the driving rack 53 drives the screw 52 to rotate through the gear and the transmission belt, so that the pre-processing mechanism 2 approaches the workpiece and stays in the middle of the workpiece for calibration and pre-processing. Then the slide continues to move forward, and the workpiece continues to approach until it fits. At this time, the pre-processing mechanism 2 disengages, and the processing mechanism 4 approaches the workpiece for processing and subsequent processing.

[0092] It should be noted that the pre-processing mechanism 2 and the processing mechanism 4 are respectively located on two sides of the moving platform 51, that is, two mechanisms, one close and one far away.

[0093] It is worth mentioning that by associating the work of each workpiece with the movement of the slide, the various work steps are guaranteed to be in a strict order with each other, reducing errors and mistakes, and improving product quality and production efficiency.
