Separation finger jumping correction and detection device for automobile diaphragm spring clutch

Abstract

The invention discloses a separation finger jumping correction and detection device for an automobile diaphragm spring clutch, which is characterized in that the separation finger jumping correction and detection device is provided with a working platform, a limit mechanism, a correction mechanism and a detection mechanism; and when the separation finger jumping correction and detection device is in use, firstly, the connection height of a separation finger of the diaphragm spring clutch is controlled in the range of (L-1)+ / -1 by the product and tolerance design and then correction and detection are carried out, wherein in the correcting and detecting process, a jack screw is driven by a servo motor, the separation finger of the diaphragm spring clutch is jacked upward to be deformed, the connection height of the separation finger reaches the specified size range by the deformation, the separation finger is ensured to jump in the specified tolerance range and L represents a separation finger connection height standard value. According to the invention, the requirement on the jumping of the separation finger of the diaphragm spring clutch can be met and reliable data of each separation finger connection height is provided.

Description

technical field [0001] The invention relates to a device for correcting and detecting the beating of the release finger of an automobile diaphragm spring clutch. Background technique [0002] The diaphragm spring clutch is a clutch made of a diaphragm spring instead of a general coil spring and a release lever mechanism. The diaphragm spring clutch has many advantages: First, because the diaphragm spring has nonlinear characteristics, it can be designed as a friction plate After wear and tear, the spring pressure can remain almost unchanged, and the pedal force when disengaging the clutch can be reduced, making the operation easy; secondly, the diaphragm spring itself also acts as a compression spring and a disengaging lever, which greatly simplifies the structure of the clutch. The number of parts is reduced, the mass is reduced and its axial dimension is significantly shortened; in addition, because the diaphragm spring and the pressure plate are in contact with the entire...

Problems solved by technology

Now the joint height of the separation finger of the product can be guaranteed to be L±1, but it is difficult to guarantee the runout of 0.6, which can only be solved by calibration. The existing method is that the operator detects the data according to the dial indicator, and then takes a reference finger size, which will exceed the tolerance The separation of the range refers to correction, the excessively high size is corrected downward, and the too low size is corrected upward, so that the joint height and runout are within the specified range

This existing method has low efficiency and poor product consistency
