Pull type clutch cover assembly assembling device and assembling method

Abstract

The invention discloses a pull type clutch cover assembly assembling device and an assembling method. The device is structured as follows: an air cylinder mechanism is vertically arranged below a work platform; the air cylinder mechanism is connected with a stigma flange which is arranged on a transmission plate and used for pushing; an ejector pin with guide function is arranged on the transmission plate; the ejector pin is matched with a guide sleeve which is assembled on the work platform and a corresponding guide hole of an assembling template, so that the stigma flange and the ejector pin on the transmission plate carry out ejection actions together under the driving of the air cylinder mechanism; and a pressing plate which is matched with the mechanism is arranged above the work platform. During the assembly, a cover assembly component is assembled on the assembling template according to assembling requirements and the air cylinder mechanism pushes the stigma flange and the ejector pin to overcome the elastic force of a cover assembly diaphragm spring so that the connection surfaces of a cover assembly transmission blade component and the pressing plate in assembly are clingy planes and then a fastening bolt can be completely screwed. The assembling device and assembling method provided by the invention are capable of effectively solving the problem of assembling quality in assembly of the cover assembly component in the prior art.

Description

technical field [0001] The invention relates to an assembly tool for an automobile clutch, in particular to an assembly device for an automobile pull-type clutch cover assembly. The invention also relates to an assembly method of the automobile pull clutch cover assembly assembly device. Background technique [0002] In the past, when the automobile pull clutch cover assembly was assembled, the usual practice was to assemble the cover assembly with all the parts to be assembled, such as the pressure plate, diaphragm spring, support ring, cover drive plate assembly, spacer and spring washer, etc. Assemble on an assembly platform in turn according to the assembly sequence and requirements, and then manually tighten their fastening bolts to complete the assembly work, but a technical problem in this assembly process is that when the bolts are tightened, the cover assembly It will rotate together with the torque of tightening the bolts. At this time, the diaphragm spring in the...

Problems solved by technology

[0002] In the past, when the automobile pull clutch cover assembly was assembled, the usual practice was to assemble the cover assembly with all the parts to be assembled, such as the pressure plate, diaphragm spring, support ring, cover drive plate assembly, spacer and spring washer, etc. Assemble on an assembly platform in turn according to the assembly sequence and requirements, and then manually tighten their fastening bolts to complete the assembly work, but a technical problem in this assembly process is that when the bolts are tightened, the cover assembly It will rotate together with the torque of tightening the bolts. At this time, the diaphragm spring in the assembly is in a free state. Other components are in an inclined state. This inclination will also raise the support ring and the cover drive plate assembly, resulting in a large gap between the bolt connection surface between the cover, drive plate assembly and the pressure plate. If there is no external pressure To overcome the elastic force of the diaphragm spring, make the connecting surface between the cover drive plate assembly and the pressure plate a plane close to each other, and carry out the bolt tightening operation when the diaphragm spring is still in an inclined state and the gap between the connecting surfaces is large. Not only the number of effective turns of the bolts actually screwed into the pressure plate is insufficient, but also the bolts cannot be fully tightened, resulting in the problem of incomplete fastening of the fastening surfaces between the components of the cover assembly. This situation does not meet the requirements of the assembly process , it will have a great influence on the assembly quality of the cover assembly

In order to solve the above problems, the assemblers of some enterprises adopt the method of pressing the cover with heavy objects or pressing by hand, but the above problems have not been solved due to the difficulty in controlling the strength or insufficient pressure, and these methods are still labor-intensive and relatively inefficient. Low, the problem that the assembly quality is difficult to guarantee

[0003] If the clutch cover assembly assembled above is used to assemble a vehicle, the diaphragm spring of the car will be unevenly stressed due to vibration and the action of the clutch pedal when the car is running. This unreliable bolt connection may cause some screws to fall off, causing the cover assembly If it fails, it will not only affect the service life of the clutch cover assembly, but also cause hidden dangers in driving safety. Therefore, it is a technical problem to be solved in the assembly of the clutch cover assembly
