Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a positioning fixture for bearing processing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings need to be clamped during processing, so a positioning fixture for bearing processing is needed.

[0003] Some conventional positioning fixtures for bearing processing use a screw to drive two clamping plates closer together, thereby clamping the bearing;

[0004] There are some problems, such as the clamping mechanism is large in size, the structure is complex, it occupies a large area, and it is difficult to cooperate with other processing equipment. For this reason, we propose a positioning fixture for bearing processing. Utility Model Content

[0009] Adjustment mechanism: It is arranged at the upper end of the sliding column, has a simple structure, can clamp the bearing by the deformation of the inner support plate, and occupies a small area, which is convenient for coordination with other equipment.

[0010] Furthermore, the internal support mechanism also includes an internal support plate, which is placed between the upper end of the internal support frame and the lower end of the sliding pressure frame. The upper inner wall of the internal support plate contacts the lower outer surface of the sliding pressure frame, and the lower inner wall of the internal support plate contacts the upper outer surface of the internal support frame, so that the bearing can be clamped by force deformation.

[0011] Furthermore, the inner support mechanism also includes a spring, and the spring is fixedly connected between the upper surface of the inner support frame and the lower surface of the sliding pressure frame. The inside of the spring is sleeved with the outer surface of the sliding column, which can be quickly reset.

[0013] Furthermore, the adjustment mechanism also includes a pressure plate and support columns. The lower surface of the adjustment knob is fixedly connected with evenly distributed support columns, and a pressure plate is fixedly connected between the lower ends of the support columns. The lower surface of the pressure plate contacts the upper surface of the sliding pressure frame and can be pressed.

[0014] Furthermore, evenly distributed support plates are fixedly connected between the upper surface of the installation base plate and the outer surface of the support frame, and evenly distributed bolt connection grooves are opened on the upper surface of the installation base plate to facilitate quick installation.

[0015] Furthermore, a locking plate is fixedly connected to the upper end of the stud for locking.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the positioning fixture for bearing processing has the following advantages:

[0017] The staff turns the adjusting knob, and the rotation of the adjusting knob drives the support column to rotate. The support column is driven downward by the adjusting knob while rotating. The support column drives the pressure plate downward, and the pressure plate drives the sliding pressure frame downward on the sliding column. The sliding pressure frame applies pressure downward to the inner support plate. The upper end of the inner wall of the inner support plate is subjected to the pressure of the sliding pressure frame, and the inner support frame provides supporting force to the lower end of the inner wall of the inner support plate. The upper and lower ends of the inner support plate are deformed and stretched outward at the same time. The inner support plate is stretched outward to clamp the bearing to be processed, thereby quickly clamping the bearing. At the same time, the height can be adjusted to increase the force on the inner support plate. The increased force on the inner support plate increases the degree of deformation, thereby clamping bearings of various diameters to adapt to more complex working environments and facilitate bearing processing. It also occupies a small area and is convenient for coordination with other processing equipment. BRIEF DESCRIPTION OF THE DRAWINGS
