A highly flexible tc positioning spreader tool

Abstract

The invention provides a highly flexible TC positioning hanger tooling, which includes a slide rail, a slide rail seat, an upper connecting plate, a lower connecting plate, a TC nut positioning block, and a bolt rod, and the slide rail seat and the bolt rod are installed on the upper connecting plate The TC nut positioning block is installed at the bottom of the upper connecting plate and corresponds to the bolt rod. The bolt rod, TC nut positioning block and the upper connecting plate constitute the upper connecting plate assembly. The slide rail passes through the slide rail seat on the upper connecting plate and connects with the lower The plates are connected, and the slide rail seat supports the upper connecting plate assembly to slide up and down along the slide rail above the lower connecting plate. The beneficial effects of the present invention are: 1. The highly flexible TC positioning hanger tooling of the present invention adds a positioning guide mechanism, so that the TC hoisting can accurately align the input shaft oil seal of the transmission front case; 2. A highly flexible TC positioning of the present invention The spreader tooling increases the flexibility of the TC lifting tool tooling. A set of tool tooling is compatible with multiple models of hoisting. At the same time, it will be compatible with multiple models of TC hoisting in the future, reducing the loss of model change.

Description

technical field [0001] The invention relates to the technical field of CVT assembly, in particular to a highly flexible TC positioning hanger tooling. Background technique [0002] The hydraulic torque converter 5 (hereinafter referred to as TC) is spline-engaged with the input shaft of the gearbox to realize the power transmission from the engine to the gearbox. After the TC is hoisted by the hoisting tool during the assembly process, it passes through the input shaft from top to bottom and is assembled to the front case 4 of the gearbox. [0003] Due to the sealing requirements of the TC and the front housing, the input shaft shaft head is designed with an input shaft O-ring 3, and the joint between the TC journal and the front housing is designed with an input shaft oil seal 2. During the TC assembly process, the input shaft O-ring 3 and the input shaft oil seal 2 need to be passed through successively. The existing TC hoisting tool does not have accurate shaft alignmen...

AI Technical Summary

Problems solved by technology

The existing TC hoisting tool does not have accurate shaft alignment function. During the TC assembly process, the TC notch is easy to cut the input shaft O-ring 3 and the input shaft oil seal 2, resulting in seal failure, TC oil leakage, and power transmission failure.

[0004] The lack of accurate positioning and guidance in the original TC hoisting process is the key path leading to the trimming of the TC notch input shaft O-ring 3 and input shaft oil seal 2, so adding positioning and guidance to the design is the main direction of improvement

[0005] The TC jaw 1 is not completely aligned with the input shaft oil seal hole. During the hoisting and assembly process, it is easy to cause the TC jaw 1 to collide with the input shaft oil seal 2, resulting in oil seal damage, seal failure, oil leakage, and torque transmission failure.
