An assembly device that facilitates the assembly of plastic bearings

Abstract

The invention discloses assembly equipment convenient to assemble a plastic bearing. A conveying belt is arranged on a frame; fixed clamping plates are arranged on two sides of the conveying belt; guide racks are arranged at the bottoms of the fixed clamping plates; support frames are arranged on the sides, far from the guide racks, of the two sets of fixed clamping plates; guide vertical rods areslidingly connected to the sides, near the support frames, of one set of fixed clamping plates; the ends, far from the fixed clamping plates, of the vertical guide rods are slidingly connected with connecting sleeves; the sides, far from the support frames, of the connecting sleeves are connected with push rods through welding; and the ends, far from the connecting sleeves, of the push rods are connected with inner ring positioning movable devices. In the assembly process, an outer ring of the bearing is clamped by using positioning grooves on the fixed clamping plates, and an inner ring of the bearing is shifted away and pushed back to an initial position through positioning rotary heads by using movement of the guide vertical rods; and the axis collinear relation of the positioning rotary heads and the positioning grooves is used for guaranteeing coaxiality of the inner and outer rings of the bearing after ball filling, so that the assembly precision and quality of the plastic bearing are guaranteed.

Description

technical field [0001] The invention relates to the field of plastic bearings, in particular to an assembly device for facilitating the assembly of plastic bearings. Background technique [0002] The plastic bearings currently used can generally be divided into plastic rolling bearings and plastic sliding bearings; the working principles of plastic rolling bearings and plastic sliding bearings can be distinguished by their names. The friction that occurs when plastic rolling bearings work is rolling friction, while plastic sliding bearings work What happens is sliding friction; the magnitude of rolling friction mainly depends on the manufacturing accuracy; and the magnitude of the friction of plastic sliding bearings mainly depends on the material of the bearing sliding surface. [0003] The existing bearing assembly technology is to install the inner ring into the outer ring first, and then stick the inner ring of the bearing on the raceway of the outer ring along the radia...

AI Technical Summary

Problems solved by technology

[0003] The existing bearing assembly technology is to install the inner ring into the outer ring first, and then stick the inner ring of the bearing on the raceway of the outer ring along the radial direction of the bearing to create a space on the other side, and then place the rolling elements along the The space generated on one side is filled into the raceway of the inner and outer rings. After the filling, the inner ring needs to be pushed back to the concentric position with the outer ring. The existing assembly device cannot guarantee the concentricity of the inner and outer rings after filling, and the quality of the bearing is very poor. Difficult to guarantee, for this reason we have designed an assembly equipment that facilitates the assembly of plastic bearings to solve the above problems
