Problems solved by technology

In this way, the pressing force is not easy to control during the pressing process, the circlip is easy to tilt, and the two ends of the opening of the circlip are easy to press against each other during the pressing process, so that the outer diameter of the circlip is larger than the center hole of the pulley during the pressing process. As a result, the circlip cannot be smoothly pressed into the center hole of the pulley, and the opening position of the circlip cannot be guaranteed, which seriously affects the assembly quality

Embodiment Construction

[0031] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0032] see Figure 1 to Figure 12 , this embodiment discloses an assembly device for special-shaped circlips with inner holes. There is a circle of horizontal circlip groove 4 for installing the circlip 1, the middle section of the circlip 1 is provided with a special-shaped section 5, and the special-shaped section 5 of the circlip 1 protrudes along the direction parallel to the axis of the circlip 1 Correspondingly, a vertical groove 6 is formed on the inner side wall of the central hole 3 of the pulley 2, and the groove 6 corresponds to the special-shaped section 5 of the circlip 1.

[0033] The device include...

Abstract

The invention discloses an inner hole special-shaped snap spring assembling device. The inner hole special-shaped snap spring assembling device comprises an expansion sleeve and a guide sleeve. The bottom of the outer side of the expansion sleeve is provided with an installation groove. The installation groove is divided into a left installation groove and a right installation groove. The left segment of a snap spring is right embedded into the left installation groove. The top end of the right installation groove is higher than the top end of the left installation groove. The bottom of the right installation groove downwards penetrates through the whole expansion sleeve. The right segment of the snap spring is sleeved with the right installation groove. The lower segment of the expansionsleeve is further provided with a vertical groove. After the snap spring and the expansion sleeve are installed, the special-shaped segment of the snap spring is embedded into the vertical groove of the expansion sleeve to prevent the snap spring from rotating relative to the expansion sleeve. The bottom of the guide sleeve is detachably installed on a belt wheel, an inverted tapered press-fittinghole is formed in the center of the guide sleeve, the snap spring is pressed into the center hole of a belt wheel in a fitting manner and embedded into the snap spring groove by downwards pressing the expansion sleeve with the snap spring, and automatic assembling of the snap spring and the belt wheel is achieved. The inner hole special-shaped snap spring assembling device has the advantage thatthe snap spring is rapidly and accurately installed into the belt wheel.

Description

technical field [0001] The invention relates to a mechanical device, in particular to an assembly device for a special-shaped clip spring with an inner hole. Background technique [0002] The pulley circlip is an important component of the CVT gearbox, so assembling the circlip into the center hole of the pulley is one of the most important processes in the assembly process of the CVT gearbox. The quality of its assembly directly affects the CVT transmission overall performance of the box. Since the installation of the circlip and the pulley requires the two ends of the circlip opening to be staggered and overlapped up and down to be loaded into the circlip groove in the center hole of the pulley, and the circlip cannot be rotated during the installation process, it is time-consuming and laborious and impossible to prevent mistakes. Due to the small diameter of the inner wall of the pulley and the deep groove of the circlip, it is easy to scratch the inner wall of the cente...
