A mold for guide wheel assembly

Abstract

The invention relates to a die for assembling a guide wheel. The device comprises an upper abutting ring and a lower abutting ring which are coaxially arranged. The inner circumferential side of the upper abutting ring is attached to the outer circumferential side of the pressing ring. An upper edge ring abutting against the side, away from the supporting ring, of the pressing ring extends in theupper abutting ring. The inner circumferential side of the lower abutting ring is attached to the outer circumferential side of the supporting ring. A lower edge ring abutting against the side, away from the pressing ring, of the supporting ring extends in the lower abutting ring. Fixing plates are detachably arranged between the upper abutting ring and the lower abutting ring in the circumferential direction at equal intervals. The fixing plates and the guide pieces are aligned in a one-to-one mode, a positioning block is embedded between the fixing plates, one end of the positioning block extends to be embedded between the guide pieces, and the positioning block is provided with a positioning cambered surface attached to the side, with the small bending radius, of the adjacent guide piece. By means of the positioning die and the fixing frame, the effects of positioning the guide piece and fixing the guide wheel during machining are achieved.

Description

technical field [0001] The invention relates to the technical field of guide wheel assembly equipment, in particular to a guide wheel assembly process and a mold used in the process. Background technique [0002] The guide pulley is a component of the torque converter. A hydraulic torque converter is a hydraulic component composed of a pump wheel, a turbine, and a guide wheel. Installed between the engine and the transmission, with hydraulic oil (ATF) as the working medium, it plays the role of torque transmission, torque conversion, speed change and clutch. [0003] Such as figure 1 As shown, the existing guide wheel includes a pressure ring A1 and a support ring A3 arranged coaxially, and a guide piece A2 is arranged at equal intervals in the circumferential direction between the pressure ring A1 and the support ring A3, and the opposite ends of the guide piece A2 extend respectively. There are clamping blocks, and socket holes are equally spaced in the circumferential ...

AI Technical Summary

Problems solved by technology

[0004] When the oil is input into the guide wheel, the guide wheel is in a rotating state, and the flow direction of the oil needs to be consistent with the rotation direction of the guide wheel. After being installed between the pressure ring and the support ring, it cannot be rotated and adjusted. This requires extremely high precision for the guide piece, the block and the insertion hole. Otherwise, it is very easy to have a deviation in the angle of the guide piece after it is fixed, resulting in the rotation of the guide wheel. There is a difference in the direction of oil flow, and the oil is in disorder, which causes the kinetic energy of the guide wheel to be lost due to the impact of the oil.
