TECHNICAL FIELD

[0002] As a vital component in mechanical transmission system, taper roller bearing is widely used in various mechanical equipment, such as automobile, engineering machinery, aerospace equipment, etc. It can bear large radial and axial combined load, and plays an irreplaceable role in ensuring the normal operation of equipment, power transmission and load bearing. Its performance directly affects the operation efficiency, stability and service life of the whole mechanical equipment. For example, in the field of automobiles, taper roller bearings are used to support and rotate the wheels. If the quality is not good, it may cause the wheels to run unevenly, produce abnormal vibration and noise, and even affect the safety of driving; in engineering machinery, taper roller bearings are used in transmission components, and their precision and reliability determine the working accuracy and efficiency of the equipment.

[0003] Traditional taper roller bearing grinding equipment has obvious deficiencies in clamping. Its clamping device is often simple in design and difficult to meet the stable clamping needs of the outer circle and the inner circle. During the grinding process, due to unstable clamping, the bearing is prone to shaking or shifting, resulting in a significant decrease in grinding accuracy. For example, when processing high-precision taper roller bearings, even a small shake can cause the size deviation of the ground bearing to exceed the allowable range, which cannot meet the requirements of high-end mechanical manufacturing. At the same time, different specifications of taper roller bearings have great differences in size, and the adjustment range of traditional clamping devices is limited, making it difficult to adapt to the clamping of bearings of various sizes. When processing bearings of different sizes, it is necessary to frequently replace the clamping device or make complex adjustments, which not only increases the production preparation time and reduces the production efficiency, but also may affect the product quality due to improper adjustment.

[0029] Embodiment two:

[0030] Please refer to Figures 1-4 On the basis of the embodiment one, it is further obtained that the inner circular clamping part 82 comprises: the guide sliding strip 821 which is fixedly arranged on the inner wall bottom of the mounting groove 811 and comprises two groups which are symmetrically arranged; the inner side wall of the guide sliding strip 821 is fixedly provided with a limiting plate 822; the outer wall of the guide sliding strip 821 is slidably connected with the L-shaped moving seat one 823; the top of the L-shaped moving seat one 823 is fixedly provided with the inner circular arc clamping plate 824 which comprises two groups which are symmetrically arranged.

[0031] One side of the L-shaped moving seat one 823 is provided with the L-shaped moving seat two 825 which is symmetrically arranged with the L-shaped moving seat one 823. The outer wall of the L-shaped moving seat two 825 is provided with a circular perforation 826.

[0032] The inner side wall of the L-shaped moving seat one 823 is fixedly installed with a through rod 827 which is matched with the circular through hole 826, and the inner side wall of the L-shaped moving seat one 823 is fixedly installed with a spring one 828 which is sleeved on the outer wall of the through rod 827.

[0034] Further, the embodiment realizes the quick adjustment of the position of the outer circular clamping plate 8110 by arranging the adjusting air cylinder 819, and the small air cylinder 8210 is used to complete the quick positioning of the inner circular arc clamping plate 824, so that the preparation time of the bearing clamping is shortened, and when different specifications of tapered roller bearings are machined, a large amount of time is not needed to spend on complex clamping device adjustment, so that it can be flexibly adapted to different sizes of tapered roller bearings.

[0035] In use, first, the operator places the tapered roller bearing to be machined on the placement ring pad 815 on the top of the ring plate placement seat 814, and the flexible material of the placement ring pad 815 can avoid scratching the outer surface of the bearing. At this time, the bearing inner hole is coaxial with the inner circular hole 813 on the support table plate 812, and the preliminary positioning is completed.

[0036] Then, the control box 2 sends an instruction to start the adjusting air cylinder 819. The piston rod of the adjusting air cylinder 819 extends to push the moving block 818 to slide in the moving sliding groove 816. Because the sliding block on the outer side of the moving block 818 is in sliding cooperation with the limiting sliding groove 817, the stable movement of the moving block 818 along the straight line is ensured. The two groups of adjusting air cylinders 819 which are symmetrically arranged are synchronously actuated to drive the outer circular clamping plate 8110 to approach the bearing outer circle, until the outer circular clamping plate 8110 is tightly attached to the surface of the bearing outer circle, so that the radial clamping of the bearing outer circle is realized.

The through rod 827 slides in the circular hole 826 to provide guidance for the movement. When the inner arc-shaped clamping plate 824 contacts the inner hole surface of the bearing, the spring one 828 and the spring two 829 are compressed to provide a buffer force, avoiding rigid contact damage to the bearing inner hole. The two groups of symmetrical inner arc-shaped clamping plates 824 support the bearing from the inside, and the outer circular clamping plate 8110 forms an inside-out cooperative clamping force, ensuring that the bearing has no displacement during grinding.

[0038] Further, the lifting hydraulic cylinder 4 is started, the mounting disc 5 is driven to move vertically through the connecting rod, the grinding mechanism 7 is adjusted to the appropriate grinding height, then the driving mechanism 6 servo motor + reducer drives the grinding mechanism 7 to grind the bearing inner and outer ring raceway parts. The grinding mechanism 7 can replace the grinding wheel with different particle sizes according to the processing requirements. The action of each cylinder and hydraulic cylinder is accurately controlled through the control box 2 to realize the radial feed and axial feed in the grinding process, and ensure that the processing size meets the design requirements.

[0039] Finally, loosen the workpiece: after grinding, the adjusting cylinder 819 and the small cylinder 8210 piston rod are retracted, the outer circular clamping plate 8110 and the inner arc-shaped clamping plate 824 are separated from the bearing surface respectively, and the operator takes out the processed bearing from the placing ring pad 815, completing a working cycle.

[0040] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features.
