Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a bearing outer ring clamp for processing needle roller bearings. Background Art

[0002] With the rapid development of science and technology, various mechanical equipment has been widely used in industrial production. In the design and manufacture of various mechanical equipment, bearings are an indispensable component, among which needle roller bearings are widely used. Needle roller bearings are roller bearings with cylindrical rollers. Relative to their diameter, the rollers are both thin and long.

[0003] The existing bearing outer ring clamps generally clamp and fix the bearing from the outside of the bearing by means of claw-type clamps, while the outer ring of the needle roller bearing is thin, and the contact area between the claws and the outer ring of the bearing is small, which can easily cause the outer ring of the bearing to deform during the processing of the needle roller bearing, affecting the quality of the needle roller bearing. Therefore, further improvements can be made. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides the following technical solutions: a bearing outer ring clamp for processing needle roller bearings, comprising a base and a bearing body, the bearing body being located at the top center of the base, baffles being fixedly installed on both sides of the base, threaded barrels being fixedly installed on the opposite sides of the baffles, an external positioning component being provided on the baffles at the threaded barrel, a slide groove being provided on the top of the base, and three groups of slide groove arrays being provided, and an internal positioning component being provided in the middle of the base.

[0005] As an optimization, the external positioning component includes a threaded rod threadedly connected in a threaded barrel, a turning handle is fixedly installed on one end of the threaded rod away from the threaded barrel, a connecting block is rotatably connected to the other end of the threaded rod, a splint is fixedly installed on one end of the connecting block away from the threaded rod, and a pad is fixedly installed on the inner side of the splint.

[0006] As an optimization, the threaded rod passes through the middle of the baffle, and the connecting block is slidably connected to the top side of the base. By turning the handle, the threaded rod can be driven to rotate inside the threaded barrel, thereby driving the connecting block to slide along the top side of the base.

[0007] As an optimization, the clamp is arc-shaped, and the material of the pad is rubber. The sliding of the connecting block will drive the clamp close to the bearing body, so that the arc-shaped clamp will be clamped on the outside of the bearing body to clamp and position it. At the same time, the pad can increase friction and avoid hard scratches on the outer surface of the bearing body.

[0008] As an optimization, the internal positioning component includes a threaded column fixedly installed in the middle of the base, a threaded sleeve is provided on the outer threaded sleeve at the top of the threaded column, a hexagonal head is fixedly installed on the top of the threaded sleeve, a ring is rotatably connected to the bottom of the threaded sleeve, and the ring is sleeved on the outer side of the threaded column, and the threaded sleeve is driven to rotate on the outer side of the threaded column by twisting the hexagonal head, which in turn drives the ring to slide along the outer side of the threaded column.

[0009] As an optimization, the outer side of the collar is rotatably connected to a push-pull rod, the bottom end of the push-pull rod is rotatably connected to a slider, and an arc support plate is fixedly installed on the top side of the slider.

[0010] As an optimization, the slider is slidably connected to the inside of the slide groove, and a rubber gasket is fixedly installed on the outside of the arc support plate, and the rubber gasket abuts against the inner wall of the bearing body. The downward sliding of the ring will push the push-pull rod to deviate downward, and then drive the slider to slide outward along the inner wall of the slide groove, thereby driving the arc support plate to tightly abut against the inner wall of the bearing body, so that the bearing can be positioned from the inside.

[0011] The beneficial effects of the utility model are:

[0012] 1. The outer ring clamp for needle roller bearing processing drives the threaded rod to rotate inside the threaded barrel by turning the handle, so it pushes the connecting block to slide along the top side of the base, so that the clamping plates on both sides are close to each other, so the bearing body located in the middle is clamped and positioned, and the pad can prevent the bearing housing from being squeezed by overpressure, thereby preventing the outer ring of the bearing from being deformed by overpressure.

[0013] 2. The outer ring fixture for processing needle roller bearings drives the threaded sleeve to rotate by turning the hexagonal head, which in turn drives the ring to slide downward, so the slider is pushed downward by the push-pull rod, causing the slider to slide outward along the inner wall of the slide groove, which in turn drives the arc support plate to press against the inner wall of the bearing body. The three sets of arc support plates press against the bearing body from three directions, so that the bearing can be positioned from the inside. BRIEF DESCRIPTION OF THE DRAWINGS
