Technical Field

[0001] This invention relates to the field of bearing processing and fixing equipment technology, specifically to hydraulic tooling for vertical machining of bearing seats. Background Technology

The inclined-face cylinder is fixed on the base plate and located on the tilting side of the rotating bridge plate. A second fixed clamp is driven on the inclined-face cylinder.

[0009] When the rotating bridge plate is in a horizontal state, the first fixing clamp limits the position of the rotating bridge plate relative to the bottom plate;

[0011] Preferably, a cover plate is bolted to the rotating bridge plate, a limiting sleeve for restricting the position of the bearing seat is fixed to the cover plate, and a lateral stop for squeezing the position of the limiting sleeve is provided on the cover plate.

[0013] Preferably, the lateral blocking component includes an abutment pad and a lateral push cylinder. The lateral push cylinder is fixed on the rotating bridge plate or the cover plate. The abutment pad is fixed at the end of the output shaft of the lateral push cylinder. When the lateral push cylinder controls the abutment pad to abut against the limiting sleeve, the auxiliary limiting bearing seat is located in the position of the limiting sleeve.

[0014] Preferably, the bottom of the cover plate is provided with a fixed shaft that passes through the cover plate, and the fixed shaft passes through the center of the bearing seat to restrict the position of the bearing seat.

Detailed Implementation

[0034] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0035] like Figure 1 As shown, the bearing housing vertical hydraulic tooling of the present invention includes a base plate 10, a rotating bridge plate 20, a limiting sleeve 40, a rotating drive component 60, and a clamping limiting component 70. The base plate 10 is provided with a rotating drive component 60, and the output end of the rotating drive component 60 is rotatably connected to the rotating bridge plate 20. The rotating bridge plate 20 is detachably provided with a limiting sleeve 40 to limit the position of the bearing housing.

[0036] The base plate 10 is provided with a clamping and limiting component 70 that limits the position of the rotating bridge plate 20;

[0037] like Figure 2 As shown, the clamping and limiting member 70 includes an inclined cylinder 71, a first fixing clamp 72, a straight cylinder 73, and a second fixing clamp 74.

[0038] The straight-face cylinder 73 is fixed on the base plate 10 and located on both sides of the rotating bridge plate 20. The straight-face cylinder 73 is driven by the first fixing clamp 72. The inclined-face cylinder 71 is fixed on the base plate 10 and located on the rotating tilt side of the rotating bridge plate 20. The inclined-face cylinder 71 is driven by the second fixing clamp 74.

[0039] The straight-face cylinder 73 and the inclined-face cylinder 71 are integrated, which makes their positions on the rotating bridge plate 20 more stable. When the rotating bridge plate 20 is in a horizontal state, the position of the rotating bridge plate 20 is limited by the clamping and restriction between the first fixed clamp 72 and the second fixed clamp 74 on the straight-face cylinder 73, in conjunction with the action of the rotating drive component 60. When the rotating bridge plate 20 is in an inclined state, the position of the rotating bridge plate 20 is limited by the clamping and restriction between the second fixed clamp 74 and the inclined-face cylinder 71 from the upper and lower sides. By limiting the position in both ways, the position of the rotating bridge plate 20 can be stabilized in both states, which facilitates the processing operation of the bearing seat.

[0040] When the rotating bridge plate 20 is in a horizontal state, the first fixing clamp 72 limits the position of the rotating bridge plate 20 relative to the base plate 10.

[0041] When the rotating bridge plate 20 is in an inclined state, the second fixing clamp 74 limits the position of the rotating bridge plate 20 relative to the base plate 10. Through the two states of the rotating bridge plate 20, different position processing operations can be performed on the bearing seat.

[0042] Specifically, the bearing housing to be processed is clamped and restricted onto the rotating bridge plate 20. The bearing housing is fixed in a horizontal position on the rotating bridge plate 20. The position between the base plate 10 and the rotating bridge plate 20 is restricted by the first fixing clamp 72, so that the bearing housing can be processed. When other parts of the bearing housing need to be processed, the rotating bridge plate 20 is controlled to rotate by the rotation drive 60, so that the rotating bridge plate 20 rotates to an inclined state, and the rotating bridge plate 20 is fixed in position by the second fixing clamp 74.

[0043] like Figure 1 As shown, a cover plate 30 is bolted to the rotating bridge plate 20, a limiting sleeve 40 for limiting the position of the bearing seat is fixed on the cover plate 30, and a lateral stop 50 for squeezing the position of the limiting sleeve 40 is provided on the cover plate 30.

[0044] like Figure 1 and Figure 5 As shown, the lateral blocking component 50 includes an abutment pad 51 and a lateral push cylinder 52. The lateral push cylinder 52 is fixed on the rotating bridge plate 20 or the cover plate 30. The abutment pad 51 is fixed at the end of the output shaft of the lateral push cylinder 52. When the lateral push cylinder 52 controls the abutment pad 51 to abut against the limiting sleeve 40, the auxiliary limiting bearing seat is located in the limiting sleeve 40.

[0045] A detachable cover plate 30 is provided on the rotating bridge plate 20. When the cover plate 30 is set as a flat plate structure, the lateral baffle 50 is located on the cover plate 30, and the compression limiting sleeve 40 is also located on the cover plate 30. With this structure, different types and sizes of compression limiting sleeves 40 can be set on different cover plates 30 according to actual needs. With this structure, the limiting device of the bearing seat can be easily replaced as a whole, making its application range wider.

[0046] A detachable cover plate 30 is provided on the rotating bridge plate 20. When the cover plate 30 is configured with a concave-convex structure, the lateral baffle 50 is located on the cover plate 30, and the compression limiting sleeve 40 is also located on the cover plate 30. With this structure, the position of the lateral baffle 50 relative to the compression limiting sleeve 40 can be selected according to actual needs, so that the lateral baffle 50 can restrict the position of the compression limiting sleeve 40. The limiting effect of the lateral baffle 50 on the compression limiting sleeve 40 is better.

[0047] When the side-push cylinder 52 is working, the abutment pad 51 at the end of the output shaft of the side-push cylinder 52 will abut against the compression limiting sleeve 40, thereby limiting the position of the compression limiting sleeve 40 and thus limiting the position of the bearing seat.

[0048] like Figure 1As shown, the rotating bridge plate 20 has a groove for storing the cover plate 30. The overall thickness of the rotating bridge plate 20 and the cover plate 30 is equal to the thickness of the edge end of the rotating bridge plate 20. This structural arrangement allows the overall thickness of the cover plate 30 after it is placed to be adjusted.

[0049] This structural design ensures that the addition of the cover plate 30 does not affect the overall thickness of the rotating bridge plate 20, allowing the use of the cover plate 30 to be done without adjusting the overall height of the rotating bridge plate 20. This makes it more versatile and convenient for processing bearing seats of different types and sizes.

[0050] like Figure 4 As shown, the bottom of the cover plate 30 is provided with a fixed shaft 80 that passes through the cover plate 30. The fixed shaft 80 passes through the center of the bearing seat to restrict the position of the bearing seat. By using the fixed shaft 80, the position of the bearing seat can be further restricted, so that the bearing seat will not shake during the processing, the processing accuracy is higher, and the processing effect of the workpiece is better.

[0051] like Figure 2-3 As shown, the cover plate 30 and the rotating bridge plate 20 are provided with multiple through threaded holes for connecting bolts, and the threaded holes on the cover plate 30 and the rotating bridge plate 20 are all one-to-one. With this structural design, when the cover plate 30 is in use, it is convenient to install the extrusion limiting sleeve 40 and the side stop 50. The bolts used for installing the extrusion limiting sleeve 40 and the side stop 50 can also limit the relative position between the cover plate 30 and the rotating bridge plate 20, making installation and disassembly operations convenient in actual use.

[0052] like Figure 3 As shown, the rotary drive component 60 includes a rotation limit seat 61, a rotating shaft 62, a gear 63, a rack 64, a direct-push cylinder 65, and a connecting seat 66. The rotating bridge plate 20 is fixed on the connecting seat 66. One end of the connecting seat 66 is fixedly connected to the rotating shaft 62. The rotating shaft 62 rotatably passes through and connects to the rotating limit seat 61. The rotating limit seat 61 is fixed on the base plate 10. The end of the rotating shaft 62 is fixedly connected to the gear 63. The gear 63 meshes with the rack 64. The direct-push cylinder 65, which drives the rack 64 to move, is fixed on the base plate 10.

[0053] Specifically, the direct-drive cylinder 65 operates, driving the rack 64 to move, thereby driving the gear 63 to rotate, causing the rotating shaft 62 connected to the gear 63 to rotate accordingly, which in turn drives the rotating bridge plate 20 to rotate, adjusting the rotating bridge plate 20 to a horizontal or inclined state.

[0054] The rotation limit seat 61 is equipped with a bearing that connects to the rotating shaft 62. The bearing is located in the rotation limit seat 61, which limits the distance between the bearing and the base plate 10, thereby facilitating the rotation of the rotating shaft 62.

[0055] The connector 66 is configured as a U-shaped structure or a right-angle structure;

[0056] When the connecting seat 66 is set as a U-shaped structure, the rotating bridge plate 20 is set in the slot of the connecting seat 66 and the rotating bridge plate 20 and the connecting seat 66 are fixed with bolts. By clamping, the position of the connected rotating bridge plate 20 can be more stable and there will be no shaking during use.

[0057] When the connecting seat 66 is set as a right-angle structure, the rotating bridge plate 20 is set in the stepped platform of the connecting seat 66. The rotating bridge plate 20 and the connecting seat 66 are fixed with bolts, which facilitates the installation and disassembly of the rotating bridge plate 20. The rotating bridge plate 20 can be taken and placed directly from above the connecting seat 66, which is simple and convenient to operate and has higher replacement efficiency.

[0058] like Figure 1-2 As shown, both the first fixed clamp 72 and the second fixed clamp 74 include a rotating connecting plate 721, a clamp 722 and a rotating shaft 723. The end of the clamp 722 is rotatably connected to the cylinder housing through the rotating shaft 723. The rotating connecting plate 721 is rotatably arranged at the middle position of the clamp 722. The bottom of the rotating connecting plate 721 is rotatably connected to the cylinder output shaft.

[0059] When the inclined cylinder 71 is working, the output shaft of the inclined cylinder 71 drives one end of the chuck 722 to move, so that the chuck 722 rotates around the rotating shaft 723 on the rotating connecting plate 721, thereby pressing and limiting the edge of the rotating bridge plate 20.

[0060] When the straight-face cylinder 73 is working, the output shaft of the straight-face cylinder 73 drives one end of the chuck 722 to move, so that the chuck 722 rotates around the rotating shaft 723 on the rotating connecting plate 721, thereby pressing and limiting the edge of the rotating bridge plate 20.

[0061] The contact area between the chuck 722 and the rotating bridge plate 20 is provided with a concave-convex layer, which makes the chuck 722 press and restrict the position of the rotating bridge plate 20 more stable and prevents wobbling.

[0062] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
