[0039] The present application provides a deep groove ball cage station transfer device for the station switching of the cage, including a first transfer arm rod 71 and a second transfer arm rod 72 arranged in parallel. A first clamping jaw 731 is provided on the first transfer arm rod 71, and a second clamping jaw 732 is provided on the second transfer arm rod 72; the first clamping jaw 731 includes a first ball pocket jaw 7311 for clamping the first ball pocket of the cage and a connecting plate limiting block 7312 for limiting and supporting the ball pocket connecting plate 12 between two adjacent first ball pockets 11; the second clamping jaw 732 includes a second ball pocket jaw 7321 for clamping the second ball pocket 13 of the cage and a ball pocket limiting block 7322 for limiting the top of the second ball pocket 13. The first clamping jaw 731 and the second clamping jaw 732 arranged oppositely drive the cage 1 to be clamped by approaching and separating through the first transfer arm rod 71 and the second transfer arm rod 72. The first clamping jaw 731 uses the first ball pocket 11 and the ball pocket connecting plate 12 of the cage 1 to position one end of the cage 1 at the position of the ball pocket connecting plate 12, and the second clamping jaw 732 supports the second ball pocket 13. The clamping and fitting of the cage is realized through the two clamping jaws, so as to achieve the positioning and clamping of the cage and realize the position consistency of the switching between different stations.

[0040] In a specific embodiment of this case, the first clamping jaw 731 includes a first limiting end face 7314 for supporting the first end of the cage 1 in the radial direction. The first ball pocket jaw 7311 includes an upper limiting claw 7315 for clamping and limiting the upper end face of the first ball pocket 11 and a lower limiting claw 7311 for clamping and limiting the lower end face of the first ball pocket 11;

[0041] The connecting plate limiting block 7312 is arranged in the middle of the first limiting end face 7314;

[0042] The upper limiting claw 7315 and the lower limiting claw 7311 include two groups distributed on both sides of the connecting plate limiting block 7312.

[0043] Further, the first limiting end face 7314 is an arc-shaped limiting end face; the diameter of the arc-shaped limiting end face 7314 is greater than the diameter of the cage 1.

[0044] The upper limiting claw 7315 is a limiting pressing plate 7315 laid flat on the upper end face of the first clamping jaw 731; the extending end of the limiting pressing plate 7315 has an upper guiding inclined surface inclined towards the lower limiting claw side;

[0045] The extending end of the lower limit claw 7311 has a lower guiding inclined surface arranged obliquely toward the limit pressing plate side.

[0046] An adjustment gap 7313 for swinging adjustment of the cage 1 is reserved between the connecting block limit plate 7312 and the ball pocket connecting plate 12.

[0047] During the preparation of the empty batch cage and the rivet-pierced cage, the cage is formed by stamping through different dies. The basic structure of the cage is formed from the annular base material, and rivet holes are punched. The annular base material is first formed once by a forming die, which includes a forming upper die and a forming lower die. Forming upper die teeth are arranged on the forming upper die, and forming lower die teeth are arranged on the forming lower die. The two are pressed and matched to preliminarily process the annular base material into a bending structure corresponding to different ball pocket positions.

[0048] The shaping die forms corresponding rolling elements, such as spherical ball pockets for spherical rolling elements or arc surface ball pockets of a basic cylindrical shape, on the bending structure. The shaping die includes a shaping upper die and a shaping lower die. A shaping core is arranged on the shaping lower die, and a shaping ball is placed on the shaping core. When the two are closed, the shaping ball re-forms the bending structure into a spherical or arc surface structure for the second time.

[0049] The punching die includes a punching upper die and a punching lower die. A punch pin is arranged on the punching upper die, and a punching hole is arranged on the punching lower die. The two are closed and matched to punch rivet holes on the ball pocket connecting part of the cage after the second forming, thus completing the preparation of the empty batch cage.

[0050] The empty batch cage is continuously conveyed to the nail-pressing die, which includes a nail-pressing upper die and a nail-pressing lower die. The empty batch cage is placed on the nail-pressing lower die, and rivets are placed into each rivet hole. A punch pin is arranged on the nail-pressing upper die. After closing the die, the punch pin on the nail-pressing upper die presses the rivets into the rivet holes.

[0051] During the process of piercing the empty batch cage and the rivet-pierced cage, both are subjected to the closing and pressing of different dies, and it is necessary to accurately position the ball pocket position and the rivet hole position to avoid damaging the cage structure during the transmission process.

[0052] By arranging the relatively disposed first clamping claw 731 and the second clamping claw 732, while switching the clamping position of the cage 1, the position positioning of each position switch is ensured.

[0053] The positioning function is realized by the first clamping jaw 731. The first clamping jaw 731 has a first limiting end face 7314 with an arc surface structure. The first limiting end face 7314 is opposite to one end of the cage 1 in the radial direction. When the first clamping jaw 731 clamps the cage 1 radially, it abuts and cooperates with the cage 1. The diameter of the first limiting end face 7314 is set to be larger than the diameter of the cage 1. The first limiting end face 7314 can realize two-point support with two adjacent first ball pockets 11, improving the support stability.

[0054] In the height direction of the ball pocket, that is, in the thickness direction of the cage 1, the first clamping jaw 731 is further provided with two first ball pocket clamping jaws 7311, which are adapted to the position of the first ball pocket 11 and are supported by two adjacent first ball pockets 11 and the ball pocket connecting plate 12 between the two first ball pockets 11. The distance between the two first ball pocket clamping jaws 7311 is set to correspond to the distance between the two first ball pockets 11, so that the clamping position falls on the first ball pocket 11.

[0055] The first clamping jaw 7311 includes an upper limiting claw 7315 for limiting the upper end face of the first ball pocket 11, and two lower limiting claws 7311 corresponding to the lower end faces of the two first ball pockets 11 respectively. Two groups of upper limiting claws 7315 and lower limiting claws 7311 respectively correspond to two adjacent first ball pockets 11. In this embodiment, preferably, the upper limiting claw 7315 of the first clamping jaw 731 is a limiting pressing plate with a plate surface structure and cooperates with the two lower limiting claws 7311 respectively.

[0056] It can be understood that the upper limiting claw 7315 and the lower limiting claws 7311 are clamped and cooperated with two adjacent first ball pockets 11. A adjustment gap 7313 is reserved between the connecting plate limiting block 7312 and the ball pocket connecting plate 12 in the middle of the two first ball pockets 11. Only by the two-point support method of the two first ball pockets 11, when the position of the cage 1 is offset, it is easy to cause the ball pocket connecting plate 12 not to correctly enter below the connecting plate limiting block 7312. By setting the limiting pressing plate with a plate surface structure, the highest points of the two first ball pockets 11 are always below the limiting pressing plate, avoiding the cage 1 from tilting. The connecting plate limiting block 7312 laterally limits the ball pocket connecting plate 12 to a predetermined position below it, realizing the end positioning of the cage 1.

[0057] At the same time, in order to facilitate the cage 1 to be inserted between the limiting pressing plate and the lower limiting claws 7311, an upper guiding inclined surface and a lower guiding inclined surface are respectively provided at the opposite protruding ends of the two, increasing the opening width, which will further improve the insertion accuracy of the cage.

[0058] In a specific embodiment of this case, the second clamping jaw 7321 includes a second limiting end face 7325 for supporting the second end of the cage in the radial direction;

[0059] The second clamping jaw 7321 includes a left jaw, a right jaw, and a middle limiting block 7322 that respectively support three adjacent second ball pockets 13.

[0060] Both the left jaw and the right jaw include limiting jaw heads 7324 that clamp and limit the upper and lower end faces of the second ball pocket. The end of the limiting jaw head 7324 is provided with a jaw head guiding inclined surface for guiding the insertion of the second ball pocket.

[0061] The middle limiting block 7322 is arranged on the upper top surface of the second clamping jaw 732, and a runout gap 7323 is reserved between the middle limiting block 7322 and the middle ball pocket among the three adjacent second ball pockets 13.

[0062] After the first clamping jaw 731 is positioned and supported by the ball pocket connecting plate 12, the second end in the radial direction of the cage 1 has a position structure where the ball pocket and the ball pocket connecting plate are located at both radial ends. By using the three adjacent second ball pockets 13 at the position of the second ball pocket 13, the second clamping jaw 732 and the second ball pocket 13 are pressed and matched to mainly achieve the purpose of balanced support.

[0063] The second clamping jaw 732 uses a left jaw, a right jaw, and a middle limiting block 7322 to clamp the end of the cage 1. When the second clamping jaw 732 cooperates with the first clamping jaw 731, it uses a method of clamping three adjacent second ball pockets 13. The left jaw and the right jaw are respectively clamped and matched with both ends of the three second ball pockets 13. Since the position of the cage 1 has been positioned on one side of the first clamping jaw 731, there will be no flipping situation.

[0064] After clamping the second ball pockets 13 at both ends, the middle second ball pocket is limited and supported by the middle limiting block 7322 at the top of the second ball pocket 13, which can ensure the clamping balance of the cage 1.

[0065] By using a limiting pressure plate and two groups of lower limiting jaws in the first clamping jaw 731, the top surface of the ball pocket connecting plate 12 is limited by the connecting plate limiting block 7312, and the position is adjusted by the adjustment gap 7313, so as to prevent the cage 1 from flipping along the direction of the station transfer.

[0066] The upper end surface of the ball pocket connecting plate 12 is limited by the connecting plate limiting block 7312. To prevent the problem of warping of the second ball pocket 13 in the width direction, after the front and rear limits are set by the left jaw and the right jaw, the upper top surface of the second ball pocket 13 is limited from warping by the middle limiting block 7322, effectively avoiding the flipping problem of the cage and realizing stable clamping and transfer.

[0067] In a specific embodiment of this case, the first transfer arm rod 71 and the second transfer arm rod 72 are respectively arranged on both sides of the mold production line of the cage 1.

[0068] The first clamping jaw 731 and the second clamping jaw 732 include multiple groups that are arranged at intervals along the lengths of the first transfer arm rod 71 and the second transfer arm rod 72, correspond to different workstations, and are used for clamping and releasing the cage.

[0069] Furthermore, first sliding frames 74 and second sliding frames 75 are respectively arranged at both ends of the first transfer arm rod 71 and the second transfer arm rod 72 in the length direction. Both the first sliding frames 74 and the second sliding frames 75 are provided with a lateral guiding device for guiding the relative approach and separation of the first transfer arm rod 71 and the second transfer arm rod 72, and a longitudinal guiding device for guiding the first transfer arm rod and the second transfer arm rod along their extending directions.

[0070] The die production line of the cage 1 has multiple processes such as a forming die, a sizing die, a punching die, and a nail pressing die that are arranged in sequence. To achieve the sequential transfer of the cage between different workstations and transfer the cage on the front-end die to the rear-end die simultaneously during each die closing process, the first transfer arm rod 71 and the second transfer arm rod 72 that are arranged in parallel are provided. The two are distributed on both sides of the die production line. When the die is opened, simultaneously, the first transfer arm rod 71 and the second transfer arm rod 72 synchronously extend the first clamping jaw and the second clamping jaw into each workstation to clamp and transfer the cage material on it.

[0071] To facilitate the clamping jaws to travel the same distance between different workstations, the same spacing is set between different die workstations. Then, when the first transfer arm rod 71 and the second transfer arm rod 72 reciprocate along the length direction by one workstation, the transfer of the cage material can be achieved once. Multiple groups of the first clamping jaw and the second clamping jaw are provided at different workstations, and each group of the first clamping jaw and the second clamping jaw is clamped and matched with the cage on the workstation. For the cage and the first clamping jaw and the second clamping jaw to adopt the same positioning structure between different workstations, the cage can be at the same stamping position when switching between different workstations, ensuring the consistency of the rivet holes and the positions for passing the nails.

[0072] Combined with the opening and closing actions of the die and the need for sequential transfer of the cage material in the direction of the workstation layout, the first transfer arm rod 71 and the second transfer arm rod 72 need to simultaneously perform the position switching actions of reciprocating back and forth, as well as the clamping and releasing actions of the cage for clamping the material in the width direction of the die. By setting the first sliding frames 74 and the second sliding frames 75, the reciprocating sliding of the two parallel first transfer arm rods 71 and the second transfer arm rods 72 in the width direction and the length direction can be synchronously performed.

[0073] The structures of the first sliding frame 74 and the second sliding frame 75 are the same. Taking one side of the first sliding frame 74 as an example, a lateral guiding device 741 and a longitudinal guiding device 743 are provided. The lateral guiding device 741 is composed of two laterally arranged guide rails that can be fixedly installed on the die rack. The longitudinal guiding device 743 is composed of two guide rails fixedly installed on the first transfer arm rod 71 and the second transfer arm rod 72 respectively. A guide rail connecting plate 742 is arranged between the lateral guiding device 741 and the longitudinal guiding device 743. Through a driving device, preferably a driving motor, the first transfer arm rod 71 and the second transfer arm rod 72 can perform synchronous lateral and longitudinal opening and closing actions, meeting the function of the cage station switching.

[0074] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather should be accorded the widest scope consistent with the principles and novel features disclosed herein.
