Description

Technical Field

[0001] The embodiments of the present application relate to the field of bearing processing technology, and in particular to a gripper for inner and outer rings of large and larger bearings. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotational accuracy. The role of a bearing is to provide support, which literally means to support the shaft, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood as being used to fix the shaft. This is included in the automatic selection of bearings. It is to fix the shaft so that it can only rotate, while controlling its axial and radial movement. In the production and manufacturing of some large bearings, it is often necessary to grasp the bearings. Therefore, a gripper for the inner and outer rings of large and above-sized bearings has been proposed.

[0003] However, existing large bearing grippers are not suitable for clamping bearings of different sizes. They have great limitations, unreliable gripping, and a low degree of automation, which delays the progress of bearing processing and affects the accuracy of the product. Summary of the Invention

[0004] In view of the above problems, an embodiment of the present application provides a gripper for the inner and outer rings of large and above-sized bearings to solve the problem that the existing large bearing gripper is not suitable for clamping bearings of different sizes, has great limitations, is not reliable in gripping, and has a low degree of automation, which delays the progress of bearing processing.

[0005] The present invention provides a gripper for inner and outer rings of large and larger bearings. The gripper comprises a mounting frame, a noise reduction cover fixedly mounted inside the mounting frame, a drive motor fixedly mounted inside the noise reduction cover, a gripping mechanism fixedly mounted on the lower surface of the mounting frame, the gripping mechanism comprising a driving component fixedly mounted on the bottom of the mounting frame, an adjusting component movably mounted on the surface of the driving component, and a clamping component movably mounted on the surface of the adjusting component.

[0006] In some embodiments, the driving component includes a limit seat fixedly mounted on the bottom of the mounting frame, an output end of the noise reduction cover and an active bevel gear located at the bottom of the mounting frame, and the outer surface of the active bevel gear is meshed with four sets of transmission components.

[0007] In some embodiments, the four transmission components are bevel gear one, bevel gear two, bevel gear three and bevel gear four, respectively. The inner walls of bevel gear one, bevel gear two, bevel gear three and bevel gear four are fixedly connected with threaded rods, and the ends of the threaded rods are rotatably connected to the inside of the limit seat.

[0008] In some embodiments, the adjusting component includes a slide seat movably mounted on the surface of the threaded rod, a limit plate is fixedly mounted on the upper surface of the slide seat, and a side surface of the limit plate is fixedly connected to the polished rod.

[0009] In some embodiments, a buffer spring is sleeved on the end of the polished rod, and a sleeve is movably mounted on the surface of the polished rod, and a mounting block is fixedly connected to the surface of the sleeve.

[0010] In some embodiments, the clamping component includes a vertical plate fixedly connected to the upper surface of the slide, a hydraulic rod is fixedly mounted on one side surface of the vertical plate, and an L-shaped connecting block is fixedly mounted on one end of the hydraulic rod.

[0011] In some embodiments, a fixing plate is fixedly connected to one end surface of the L-shaped connecting block, the bottom of the fixing plate is fixedly connected to the upper surface of the mounting block, and an internal and external dual-purpose clamp is fixedly installed on one side surface of the fixing plate.

[0012] Through the above scheme, the driving motor installed inside the noise reduction cover drives the active bevel gear to rotate, and the noise reduction cover can effectively reduce the noise of the driving motor. The active bevel gear is meshed with bevel gear one, bevel gear two, bevel gear three and bevel gear four, so it also drives the threaded rod installed inside it to rotate, and the threaded rod drives the slide to slide on its surface. By setting a light rod, the sleeve is matched to the mounting block so that the clamping component can slide, and through the buffer spring, the impact caused by inertia is buffered when retreating, which is beneficial to improve the service life; the L-shaped connecting block is pushed by the hydraulic rod installed on one side surface of the vertical plate, and the fixed plate is driven by the L-shaped connecting block to slide on the surface of the light rod, so that the internal and external dual-purpose clamps can clamp bearings of different sizes, thereby improving the utilization efficiency of the gripper.

[0025] In the technical solution of the embodiment of the present application, the driving motor 3 installed inside the noise reduction cover 2 drives the active bevel gear 42 to rotate. The noise reduction cover 2 can effectively reduce noise for the driving motor 3. The active bevel gear 42 is engaged with the bevel gear 1 43, the bevel gear 2 44, the bevel gear 3 45 and the bevel gear 4 46, so it also drives the threaded rod 47 installed inside it to rotate for adjustment.

[0026] According to other embodiments of the present application, Figure 3 As shown, the adjusting component includes a slide 5 movably mounted on the surface of the threaded rod 47, a limit plate 51 is fixedly mounted on the upper surface of the slide 5, a light rod 52 is fixedly connected to one side surface of the limit plate 51, a buffer spring 53 is sleeved on the end of the light rod 52, and a sleeve 54 is movably mounted on the surface of the light rod 52, and a mounting block 55 is fixedly connected to the surface of the sleeve 54.
