Description

Technical Field

[0001] The invention relates to the technical field of metal quenching processing, in particular to an automatic quenching device for manufacturing automobile ball cage parts. Background Art

[0002] The automobile ball joint, also known as the constant velocity universal joint, is an important component in the vehicle transmission system. Its function is to transfer the engine power from the transmission to the drive wheel to drive the vehicle at high speed. In order to ensure the strength, hardness and toughness of the automobile ball joint, the inner groove of the ball joint and the transmission joint surface such as the ball joint spline need to be surface quenched.

[0003] Due to the structural limitations of the automotive ball joint, the size and structure of the two ends are quite different, so they need to be processed separately during quenching. The most traditional processing method mainly relies on manual labor, which has poor precision and unsatisfactory quenching effect. Therefore, manual quenching has been basically eliminated in the production field of automotive ball joints.

[0004] The existing automated ball cage quenching equipment has made certain improvements to the traditional processing methods, greatly improving the degree of automation. For example, the Chinese patent authorization announcement number CN10582118B, the patent name is an automatic quenching machine tool, which discloses "grabbing the workpiece that has been quenched in the first station, and rotating the workpiece through the rotating arm, waiting for the quenching of the workpiece in the second station", which can be undoubtedly identified as the function of rotating the workpiece and moving it from the first quenching position to the second quenching position through the rotating arm. However, there are some obvious defects in its structure, and no solution is proposed in the content. In actual processing, the workpiece needs to be fixed in a certain position to keep it stable during quenching, that is, a specific tooling for fixing the workpiece is required in both the first quenching station and the second quenching station. Since the rotating arm in the invention directly grabs the workpiece on the first quenching station and directly rotates and puts it into the second quenching station, there will be contact and collision between the workpiece and the tooling in practice, resulting in scratches or even damage to the workpiece, affecting the quality of the finished product.

[0048] The feeding mechanism 7 includes a translation slide assembly 12 arranged on the transverse bracket 3, a lifting platform assembly 13 arranged on the translation slide assembly 12, and a feeding and placing device 14 fixed on the lifting platform assembly 13;

[0053] Preferably, the forward quenching member 15 and the reverse quenching member 18 are both made of thyristors.

[0054] In this embodiment, the translation slide assembly 12 includes a transverse support plate 22 disposed near the transverse bracket 3, a translation guide rail 23 disposed on the transverse bracket 3, a translation guide rail slider 24 disposed on the transverse support plate 22 and slidingly matched with the translation guide rail 23, a transverse translation motor 25 disposed on the transverse support plate 22, a transverse rack 26 disposed on the transverse bracket 3, and a transverse transmission gear 27 disposed on the output shaft of the transverse translation motor 25 and meshing with the transverse rack 26. In this embodiment, a specific structure of the translation slide assembly 12 is provided. When in use, the transverse translation motor 25 provides power for the transverse movement of the entire translation slide assembly 12. The stability and position accuracy during transverse translation are ensured by the cooperation of the transverse rack 26 and the transverse transmission gear 27, and the cooperation of the sliding of the translation guide rail 23 and the translation guide rail 23.

[0055] In this embodiment, the lifting platform assembly 13 includes a longitudinal support plate 28, a lifting guide rail 29 fixed on the longitudinal support plate 28, a lifting guide rail slider 30 fixed on the transverse support plate 22 and slidingly matched with the lifting guide rail 29, a longitudinal rack 32 fixed on the longitudinal support plate 28, a longitudinal lifting motor 31 fixed on the transverse support plate 22, and a longitudinal transmission gear 33 arranged on the longitudinal motor output shaft and meshing with the longitudinal rack 32. In this embodiment, a specific structure of the lifting platform assembly 13 is provided, the longitudinal lifting motor 31 provides the entire lifting platform assembly 13 with longitudinal lifting power, the longitudinal rack 32 cooperates with the longitudinal transmission gear 33, and the longitudinal guide rail slides and cooperates with the lifting guide rail 29, so as to ensure stability and position accuracy during the lifting process; and the lifting platform assembly 13 is fixedly arranged on the transverse support plate 22, so that when the translation slide assembly 12 moves, the transverse translation function can be realized at the same time.

[0056] Since the feeding mechanism 7, the turning mechanism 9, and the unloading mechanism 11 all adopt the translation slide assembly 12 and the lifting platform assembly 13, their mechanical structures and operating principles are the same, and their shapes and sizes can be adjusted according to actual needs, and there may be deviations.

[0057] In this embodiment, the feeding and placing device 14 includes a feeding power motor 34 fixed on the longitudinal support plate 28 in the feeding mechanism 7, and a feeding mechanical arm 35 driven by the feeding power motor 34.

The shifting and placing device 20 includes a material moving power motor 38 fixed on the longitudinal support plate 28 in the unloading mechanism 11, and a material moving mechanical arm 39 driven by the material moving power motor 38. In this embodiment, the specific structures of the feeding and placing device 14, the flipping and placing device 17 and the shifting and placing device 20 are respectively provided, all of which adopt the method of mechanical arms to realize the functions of loading, shifting, flipping and unloading. In particular, through the setting of the flipping robot arm 37, in the step of realizing the flipping of the workpiece 62, the workpiece 62 is first clamped from the previous tooling and placed in mid-air, then flipped at the same time, and then placed in the next tooling, thereby eliminating the risk of friction and collision between the workpiece 62 and the tooling, and ensuring that the workpiece 62 is intact during the movement and flipping process.

[0058] In the prior art, the unloading of the material after the quenching treatment of the ball cage needs to be realized by a mechanical arm. After the unloading is completed, the mechanical arm moves back to perform another material transfer operation. However, the two actions of unloading and transferring cannot be performed at the same time, resulting in a decrease in production efficiency. In order to solve the above problems, in this embodiment, a new unloading and placing device 21 dedicated to unloading is provided. The unloading and placing device 21 includes a push-out cylinder 40 arranged on the machine tool body 2, a rotating motor 41 connected to the push-out cylinder 40, a transmission rod 42 connected to the rotating motor 41, a cylinder seat 43 fixed on the transmission rod 42, a double cylinder 44 with a two-way rod arranged on the cylinder seat 43, and a unloading and placing clamp 45 driven by the double cylinder 44. The push-out cylinder 40 and the rotating motor 41 in this embodiment can realize the movement and flipping functions of the unloading and placing clamp 45, so that space can be freed up when the quenching function is performed, and the unloading and placing clamp 45 can be effectively protected. When unloading, the double cylinder 44 is moved to the specified position by pushing out the cylinder 40, and then the double cylinder 44 is started to tighten and clamp the unloading and picking-up clamp 45, and then the rotating motor 41 is started to drive the workpiece 62 to rotate and leave the reverse workpiece quenching fixture 6. At the same time, the reverse workpiece quenching fixture 6 can be reset. Finally, the push-out cylinder 40 is started again to drive the entire device to move to the unloading platform. Due to the previous flipping action, the big head end of the workpiece 62 can be at the bottom, so that after loosening the unloading and picking-up clamp 45, the workpiece 62 can be stably supported on the unloading platform, which greatly reduces the possibility of the workpiece 62 falling and being damaged.

[0059] If each component can have a higher linkage and transposition coordination when working, the production efficiency can be improved to a higher degree. In this embodiment, the machine tool body 2 is also provided with a drag chain moving component 46 and a mounting frame 47, and the forward induction heating quenching device 16 and the reverse induction heating quenching device 19 are fixed on the mounting frame 47, and the mounting frame 47 is fixed to the transverse bracket 3, and the transverse bracket 3 is translated left and right through the drag chain moving mechanism. Through the setting of the drag chain moving component 46, the overall translation of the mounting frame 47 can be driven, thereby also realizing the movement function of the forward induction heating quenching device 16 and the reverse induction heating quenching device 19 fixed on the mounting frame 47, and then cooperate with other components to simultaneously transpose to form a linkage effect.

[0060] In this embodiment, a material storage tray 48 and a material unloading platform 49 are also included. The material storage tray 48 is placed outside the machine tool body 2, and the material unloading platform 49 is located inside the machine tool body 2. A material taking window corresponding to the position of the material unloading platform 49 is provided on the machine tool body 2. When this embodiment is used, the staff places the workpiece 62 to be quenched on the material storage tray 48, and the feeding robot 35 in the feeding and placing device 14 can automatically clamp the workpiece 62 on the material storage tray 48 and put it into the machine tool body 2 for processing; the workpiece 62 after quenching is moved to the material unloading platform 49 by the action of the material unloading and placing device 21, and the staff can take the finished workpiece 62 out of the machine tool body 2 from the material taking window.

[0061] In this embodiment, the forward workpiece quenching tool 4 includes a first base plate 50 and a first tooling table 51, and the first tooling table 51 is connected to the first base plate 50 through a first adjusting screw 52; the transfer tool 5 includes a second base plate 54 and a second tooling table 55, and the second tooling table 55 is connected to the second base plate 54 through a second adjusting screw 56, and the second adjusting screw 56 is also sleeved with a buffer spring 57, and the second tooling table 55 is provided with a first reverse hole 58 that is reversely matched with the workpiece 62; the reverse workpiece quenching tool 6 includes a third tooling table 59, and the third tooling table 59 is provided with a second reverse hole 60 that is reversely matched with the workpiece 62, and a side of the second reverse hole 60 is provided with an air avoidance groove 61. In this embodiment, specific structures of the forward workpiece quenching tool 4, the transfer tool 5 and the reverse workpiece quenching tool 6 are respectively provided, and the characteristics are: first, a buffer spring 57 is provided in the transfer tool 5, so that the workpiece 62 that has just been turned over can be placed therein more smoothly; second, an air avoidance groove 61 is opened on one side of the third tooling table 59 to make room for turning and moving the workpiece 62 when used in conjunction with the unloading and placing device 21.
