Problems solved by technology

However, this positioning method can easily cause the position of the tooth fan to shift during the welding process, which will cause the uneven meshing gap between the tooth fan and the motor transmission teeth during the operation of the lifter, resulting in abnormal noise, and also cause the active arm The impact of the buffer block at the outer end and the slide rail produces abnormal noise, which affects the service life of the lifter

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] The gear fan welding tool provided by the present invention comprises a plate body 10, two first positioning pins 11 symmetrical to each other are arranged on the plate surface of the plate body 10, and a self The positioning pin 11 extends to the groove 12 at one side edge of the plate body 10, and the groove 12 is respectively provided with a second positioning pin 13 and a third positioning pin 14 along the groove length direction. The two first positioning pins 11 are used to position the tooth sector 20. Specifically, the two positioning pins 11 are inserted into the two positioning holes 21 on the tooth sector 20, so as to realize the positioning of the tooth sector 20. position. Because there is a certain bending between the front end of the active arm 30 , that is, the part welded with the gear sector 20 and the rear end of the active arm 30 , the front...

Abstract

The invention relates to a sector welding tool which can enable the welding positions between a sector and a master arm to be accurate, avoid the abnormal sound which is generated during the operation process of a lifter, and prolong the service life of the lifter. The sector welding tool comprises a plate body, wherein first location pins which are symmetrical to each other are arranged on the surface of the plate body, a groove which extends from the outer parts of the location pins to the edge of one side of the plate body is arranged on a central axis between the two first location pins, and a second location pin and a third location pin are respectively arranged in the groove along the length direction of the groove. Through the technical scheme, the tool adopts a double-point positioning mode, so the six freedom degrees of the sector can be effectively restrained, the sector is accurately positioned, the welding positions between the sector and the master arm are enabled to be accurate during the welding process, the abnormal sound which is generated during the operation process of the lifter is avoided, and meanwhile, the service life of the lifter is prolonged.

Description

technical field [0001] The invention relates to the field of automobile door yoke-type glass lifters, in particular to a gear fan welding tool. Background technique [0002] At present, the car door glass generally adopts the fork-arm lifter. The key parts of this lifter include the gear fan and the active arm. On the device, the main arm is welded to the fan surface of the gear fan. In the prior art, an external tooth circle matching the radian of the outer sector surface of the tooth sector is generally arranged on the tooling device, and two eccentric wheels are arranged at both ends of the inner tooth surface of the tooth sector to realize the positioning of the tooth sector. However, this positioning method can easily cause the position of the tooth fan to shift during the welding process, which will cause the uneven meshing gap between the tooth fan and the motor transmission teeth during the operation of the lifter, resulting in abnormal noise, and also cause the act...
