Description

Technical Field

[0001] The utility model relates to the technical field of spherical bearing manufacturing, in particular to a quick material taking device for press-fitting spherical bearings. Background Art

[0002] Spherical plain bearings are a type of sliding bearing with a special structure, consisting primarily of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. These bearings are characterized by their ability to withstand heavy loads, including radial, axial, or combined radial and axial loads. Because the sliding surface of a spherical plain bearing is spherical, it can tilt within a certain range (i.e., self-aligning motion), making it suitable for low-speed swinging motion and low-speed rotation. Spherical plain bearings can function properly even when there is significant misalignment between the bearing shaft and the shaft housing bore.

[0003] Spherical plain bearings have many advantages, including a simpler structure than rolling bearings, greater load capacity, impact resistance, corrosion resistance, wear resistance, self-alignment, and good lubricity. These characteristics make spherical plain bearings widely used in industries such as engineering hydraulic cylinders, forging machines, construction machinery, automation equipment, automotive shock absorbers, and hydraulic machinery.

[0004] The existing joint bearing press-fitting process requires manual loading and unloading, which not only increases the risk of human injury, but is also time-consuming and labor-intensive, low-efficiency, and is not conducive to the efficient production and processing of equipment.

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0025] like Figures 1-6 As shown, the present embodiment provides a quick material removal device for press-fitting of joint bearings, comprising a base 1, with fixed plates 6 symmetrically arranged on both sides of the top of the base 1, a rotating rod 16 rotating inside the fixed plate 6, a straight support rod 8 fixed to one side of the top of the rotating rod 16, a loading ring 10 and a unloading lever 12 are arranged at one end of the outside of the straight support rod 8, a rubber sleeve 11 is glued to the inner wall of the loading ring 10; a transmission gear 13 is nested at the bottom of the rotating rod 16, a driving residual gear 14 is meshed between the transmission gears 13, a transmission assembly 15 is mounted on the bottom of the driving residual gear 14, and a motor 5 is mounted on the bottom of the transmission assembly 15.

[0026] In the above embodiment, there are two groups of left and right driving gears 14, and the teeth of the two groups of driving gears 14 are located on the same side. The two groups of driving gears 14 rotate synchronously. When the left driving gear 14 rotates the driving transmission gear 13, the right driving gear 14 is in idle rotation. At this time, the left rotating rod 16 drives the loading ring 10 and the workpiece it carries for assembly to enter the top of the mold base 3 and stop. The stop position is controlled by the motor 5. The motor 5 is set to the stop sequence by the program in the external control device. After stopping, the press presses down the unassembled workpiece. At this time, the diagonal support rod 9 and the rotating ring 7 play the role of supporting the loading ring 10. The unassembled workpiece can be pushed lightly and fall into the mold base 3. The press is reset, the motor 5 continues to rotate, the left driving gear 14 loses engagement, the spiral spring 17 in the left rotating rod 16 recovers its deformation, resets the unloaded loading ring 10, the motor 5 stops, and the press presses down to merge the outer and inner rings of the workpiece.

[0027] After the merging is completed, the press is reset, the motor 5 continues to rotate, the driving residual gear 14 on the right engages the transmission gear 13 on the right to drive the rotating rod 16 to rotate, and the rotation drives the unloading lever 12 to push out the merged workpiece.

[0028] A volute spring 17 is also clamped in the inner wall of the fixed disk 6. One end of the volute spring 17 is fixedly connected to the rotating rod 16, and the other end of the volute spring 17 is welded and fixed to the inner wall of the fixed disk 6. The volute spring 17 has a rotational thrust for automatic retraction and reset.

[0029] A rotating ring 7 is rotatably provided on the outer wall of the fixed disk 6, and an oblique support rod 9 is fixed between the outer wall of the rotating ring 7 and the straight support rod 8. The loading ring 10 and the unloading lever 12 are both detachably installed on the straight support rod 8. The oblique support rod 9 cooperates with the rotating ring 7 to provide stable rotation for the straight support rod 8.

[0030] The rotating rod 16 and the inner wall of the base 1 are limited by bearings. There are two groups of transmission gears 13 and driving residual gears 14. The two groups of driving residual gears 14 rotate in the same direction.

[0031] A processing table 2 is fixed at the top center of the base 1, and a mold base 3 is fixed on the processing table 2. A workpiece body 4 is movably placed in the mold base 3. The workpiece body 4 is the spherical bearing body, which consists of an outer ring and an inner ring. The mold base 3 is the lower mold in the processing mold, and a spring is installed in the inner cavity. After the outer ring and the inner ring are combined, the spring will lift the workpiece to the top of the mold base 3, and it can be taken out from the slot on one side of the top of the mold base 3.

[0032] The motor 5 is fixed on the ground.

[0033] Working principle of the device: When in use, the device is installed and used in conjunction with a press, and the motor 5 is connected to the control system of the press and works synchronously.

[0034] The staff aligns the outer ring and inner ring of the spherical bearing and puts them into the loading ring 10. The bottom of the outer ring is supported by the rubber sleeve 11 and will not fall out of the loading ring 10. The driving motor 5 drives the driving gears 14 on both sides to rotate through the transmission assembly 15. When the driving gear 14 on the left engages with the transmission gear 13 and rotates, the rotating rod 16 drives the straight support rod 8 to move the loading ring 10 carrying the workpiece to the top of the mold base 3. The machine is stopped and the press pushes the workpiece out of the loading ring 10 with appropriate pressure and drops it into the processing groove of the mold base 3. The press is reset and the left side The driving residual gear 14 loses its meshing force, the spiral spring 17 compressed by the rotating rod 16 in the fixed plate 6 recovers its deformation, the loading ring 10 returns to its initial position, the press presses down to close the mold, presses the inner ring into the outer ring, and the press resets. The spring in the mold base 3 pushes the combined workpiece to the top of the mold base 3. At this time, the driving residual gear 14 on the right engages the transmission gear 13 to rotate, the rotating rod 16 on the right rotates, and drives the straight support rod 8 to rotate, driving the unloading lever 12 to rotate, pushing the ejected workpiece out of the open slot of the mold base 3 to complete the unloading.

[0035] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
