Abstract

PURPOSE:To improve workability and quality by a method wherein, during relative coupling of a control shaft with a manual valve, it is detected by a detecting means whether the press force is ordinary and a spring is functioned normally. CONSTITUTION:By means of an assembly unit, a valve body unit 4 is placed on a torque converter case 2, and a manual valve 5 is inserted leftwardly deep. A press sleeve 60 is moved rightward by means of an air cylinder 55 of a press means 54, and the manual valve 5 is pressed by a press lever 61 through the force of a spring 64. When a roller spring 8 and a roller 9 are omitted or a spring force is weak, a proximity switch 65 is left turned OFF, and the valve is decided to be poor. Meanwhile, when it is nondefective, the valve 5 is moved rightward by means of the press lever 61 and a base end is collided with a coupling lever 51. Through operation of a coupling air cylinder 50, the coupling lever 51 is brought into abut contact with a control shaft 10 to couple the control shaft 10 with the manual velve 5. This constitution enables improvement of productivity without needing a special inspection process.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides for attaching a valve body unit and a control shaft of an automatic transmission to a torque converter case, and improving operability of a manual valve pre-assembled in the valve body unit. The present invention relates to an assembly device for an automatic transmission that connects a manual valve and a control shaft to each other while detecting.

6 The manual valve built into the valve body unit of an automatic transmission shifts between neutral and 1 depending on the operation of the shift lever.
In order to be able to step-by-step switch to each operation position such as speed to 4th speed and reverse, we form a recess in the manual valve corresponding to the operation position of the manual valve and adjust the manual valve spring. A locking member such as a bottle is elastically engaged with this recess by a spring force.

When operating the shift lever to switch the manual valve to a desired operating position, it is important for quality control that the operating reaction force be within a predetermined range.

In addition, the operability of a manual valve can be checked when assembling the manual valve into the valve body unit. If this occurs, the manual valve spring may not be able to function normally, so it is necessary to check the operability of the manual valve again when installing the valve body unit to the torque converter case.

However, in the past, the work of attaching the valve body unit and control shaft to the torque converter case was carried out manually, and the work of joining the control shaft to the manual valve required the worker to stand on the manual valve and operate it. Because the work was done while checking the accuracy of the work, the judgment of operability was subjective, depending on the worker's posture, physical condition, fatigue, etc., and there were also individual differences between workers, resulting in variations in quality. There was a problem.

The present invention relates to an improvement of an assembly device for an automatic transmission that overcomes such difficulties, and relates to an assembly for attaching a valve body unit and a control shaft of an automatic transmission to a torque converter case. In the apparatus, a body unit gripping means for gripping the valve body unit, a shaft gripping means for rotatably gripping the control shaft, and a manual valve that comes into contact with an end of a manual valve pre-assembled in the valve body unit. a pressing means for pressing the control shaft toward the control shaft; a detecting means for detecting the pressing force of the pressing means; and a detecting means for detecting the pressing force of the pressing means; The invention is characterized by comprising a coupling means for coupling.

Since the present invention is configured as described above, the valve body unit is gripped by the body unit gripping means, and the control shaft is rotatably gripped by the shaft gripping means. The unit and control shaft can be transported and installed onto the torque converter case.

With the valve body unit and control shaft installed in the torque converter case, the pressing means is brought into contact with the end of the manual valve that has been pre-assembled in the valve body unit, and the manual valve is moved toward the control shaft side. The coupling means can be pressed to engage the control shaft in cooperation with the coupling means to couple the control shaft to the manual valve.

During the mutual coupling operation between the control shaft and the manual valve, the detection means detects the pressing force of the pressing means and determines whether the manual valve spring engaged with the manual valve is functioning normally. can be detected.
