[0023] like Figure 2 As shown, the internal straightening mechanism 5 also includes a lifting push cylinder 52, which is installed vertically upward. The diameter straightening kit 51 is connected to the piston rod end of the lifting push cylinder 52. When the piston rod of the lifting push cylinder 52 is extended or retracted, it can drive the diameter straightening kit 51 to perform vertical lifting movement. During the vertical lifting movement of the diameter straightening kit 51, the switching between the diameter straightening operation and the discharging operation can be completed.

[0024] like Figure 2As shown, the diameter adjustment kit 51 includes a diameter adjustment column 511, a fixed plate 512 and a movable plate 513. The bottom end of the diameter adjustment column 511 is fixedly connected to the piston rod end of the lifting push cylinder 52. The diameter adjustment column 511 can be pushed by the piston rod of the lifting push cylinder 52. The outer diameter size of the diameter adjustment column 511 is the standard size of the inner ring of the bearing ring. During the diameter adjustment operation, the bearing ring workpiece is pressed downward by the extrusion sleeve 23, so that the bearing ring workpiece can be inserted into the diameter adjustment column 511 and move a stroke along the length direction of the diameter adjustment column 511, thereby completing the diameter adjustment operation on the inner ring of the bearing ring workpiece (the bearing ring The workpiece has just come off the hot forging production line and is in a high-temperature state as a whole. The hot extrusion can deform the non-standard inner ring so that the size of the inner ring matches the outer diameter of the sizing column 511 to achieve the sizing effect). In the utility model, the extrusion sleeve 23 is provided with an inner hole, and the size of the inner hole is larger than the outer diameter of the sizing column 511. When the extrusion sleeve 23 descends, it only forms a downward extrusion effect on the bearing ring workpiece. The fixed plate 512 is fixedly connected to the outer wall of the sizing column 511, and the movable plate 513 is movably sleeved on the outer side of the sizing column 511. The movable plate 513 is arranged parallel to the fixed plate 512. The movable plate 513 is parallel to the fixed plate 512. A plurality of elastic supports 514 are installed between the disks 512, and the plurality of elastic supports 514 are evenly arranged. The elastic supports 514 play a lifting effect on the movable disk 513. The elastic supports 514 include a guide column 5141 and a spring 5142. The top of the guide column 5141 is fixedly connected to the movable disk 513, and the bottom of the guide column 5141 penetrates the fixed disk 512 for installation. The bottom of the guide column 5141 is fixedly connected to the limited seat 5143, and the spring 5142 is sleeved on the outside of the guide column 5141. The upper end of the spring 5142 is connected to the movable disk 513, and the lower end of the spring 5142 is fixedly connected to the limited seat 5143. The end is connected to the fixed plate 512, the guide column 5141 plays a role in guiding the movement of the movable plate 513, the movable plate 513 plays a role in elastic support for the movable plate 513, the diameter of the limit seat 5143 is larger than the diameter of the guide column 5141, the limit seat 5143 plays a role in limiting the upper limit of the movement of the movable plate 513, when the movable plate 513 only has the elastic force of the spring 5142, the movable plate 513 can be lifted to the upper limit position by the elastic force, at this time, the limit seat 5143 is in contact with the lower end surface of the fixed plate 512, and the upper end surface of the movable plate 513 is flush with the top of the full-diameter column 511.

[0025] like Figure 2As shown, the sizing area 11 is provided with a first through hole 111, the outer diameter of the movable disk 513 matches the first through hole 111, and the first through hole 111 is arranged on the upward movement trajectory of the movable disk 513. The lifting cylinder 52 can drive the sizing kit 51 to move upward as a whole. At this time, the movable disk 513 is only subjected to the elastic force of the spring 5142. Therefore, the movable disk 513 is at the upper limit of movement. After the sizing kit 51 rises to the upper limit position, the movable disk 513 just fills the first through hole 111, and the upper end surface of the movable disk 513 is flush with the table surface of the sizing area 11. The bearing ring workpiece that slides down from the feed slide 3 just falls into the sizing area 11. In the utility model, the diameter of the movable disk 513 is larger than the diameter of the bearing ring workpiece, thereby ensuring that the bearing ring workpiece can be lifted by the movable disk 513.

[0026] like Figure 4 As shown, the positioning mechanism 4 includes three positioning push cylinders 41, and the three positioning push cylinders 41 are evenly installed around the first through hole 111. The piston rod end of the positioning push cylinder 41 is connected with a positioning push plate 42, and the positioning push plate 42 is arranged toward the center direction of the first through hole 111. After the bearing ring workpiece falls into the diameter adjustment area 11, the three positioning push cylinders 41 of the positioning mechanism 4 start to extend and retract synchronously, and form three-point positioning through the positioning push plate 42, so that the bearing ring workpiece accurately falls on the movable disk 513, and the inner ring of the bearing ring workpiece is kept concentric with the diameter adjustment column 511, and then the extrusion sleeve 23 is opened and descended. Since the movable disk 513 is elastically supported, the extrusion sleeve 23 can push the bearing ring workpiece and the movable disk 513 to descend together. At this time, the spring 5142 is compressed, and the bearing ring workpiece can move along the length direction of the diameter adjustment column 511 to form a diameter adjustment effect, as shown in FIG. Figure 3 As shown, a tapered guide head 5111 is provided at the top of the diameter adjustment column 511. The guide head 5111 can ensure that the bearing ring workpiece is smoothly inserted into the diameter adjustment column 511 to ensure that the diameter adjustment operation can be completed smoothly. After the diameter adjustment is completed, the extrusion sleeve 23 rises, and the movable disk 513 loses the downward pressure. Under the elastic force of the spring 5142, the movable disk 513 can move upward to drive the bearing ring workpiece to separate from the outer wall of the diameter adjustment column 511. Sometimes the bearing ring workpiece and the outer wall of the diameter adjustment column 511 are tightly engaged, and the elastic force of the spring 5142 is not enough to push the movable disk 513 upward. Therefore, the utility model also installs a plurality of disengagement push cylinders 515 at the position of the fixed disk 512 to assist in completing the disengagement operation. Figure 2 As shown, the disengagement push cylinder 515 is installed vertically upward, and the movable plate 513 can be driven to move upward by extending the piston rod of the disengagement push cylinder 515. A plurality of disengagement push cylinders 515 are evenly distributed, and the number of installed disengagement push cylinders 515 is not less than two, to ensure that the upward thrust is uniform and sufficient. When performing the calibrating operation, the piston rod of the disengagement push cylinder 515 must remain fully retracted so as not to interfere with the calibrating operation. The piston rod of the disengagement push cylinder 515 is extended only when the bearing ring workpiece needs to be disengaged.

[0027] like Figure 2 As shown, the discharging mechanism 6 includes a discharging platform 61 and a discharging slide 63. A second through hole 611 is opened on the discharging platform 61. The size of the second through hole 611 matches the outer diameter size of the movable disk 513. The second through hole 611 is arranged on the downward movement trajectory of the movable disk 513. The sizing kit 51 can perform sizing when it moves to the upper limit position. After sizing, the sizing kit 51 descends as a whole. During the descent, the disengagement push cylinder 515 is started, and the movable disk 513 rises to the upper limit position. The bearing ring workpiece is disengaged from the sizing column 511, and the bearing ring workpiece is lifted on the movable disk 513. After the kit 51 drops to the lower limit position, the movable disk 513 can fill the second through hole 611, and the upper end surface of the movable disk 513 can be flush with the surface of the discharge platform 61 to achieve docking. A discharge push cylinder 62 is installed on the discharge platform 61, and the piston rod end of the discharge push cylinder 62 is connected to a discharge push plate 621. The discharge slide 63 is installed at an angle, and the high point of the discharge slide 63 is connected to the discharge platform 61. The discharge push plate 621 is set toward the direction of the discharge slide 63. When the piston rod of the discharge push cylinder 62 is extended, the bearing ring workpiece on the movable disk 513 can be pushed into the discharge slide 63, so as to realize the natural sliding output of the bearing ring workpiece.
