Embodiment Construction

[0013] The triangular bracket spin riveting method, the triangular bracket 1 has a bearing sleeve 2, the bearing sleeve 2 has a bearing hole, and the bearing hole is used to install the bearing 3, including the following steps:

[0014] First, press the bearing 3 into the bearing hole, and make the upper end surface of the bearing 3 sink 2-5mm from the upper edge of the bearing hole; step), the tapered sleeve continuously squeezes the upper edge of the bearing sleeve 2 when it is pressed down, so that the upper edge of the bearing sleeve 2 is inclined inward; finally, a rotating central shaft 4 is provided, and the lower end of the central shaft 4 has a crossing pin shaft. There are rollers 5 at both ends of the shaft. Place the triangular bracket 1 directly under the center shaft 4. The rollers 5 are located on the edges of both sides of the bearing sleeve 2. The center shaft 4 moves down slowly so that the roller 5 continuously spins the top of the bearing sleeve 2. edge unt...

Abstract

The invention discloses a method for rotatably riveting an A-frame. A bearing sleeve is arranged in the A-frame, a bearing hole is formed in the bearing sleeve and is used for installing the bearing, and the method includes the steps as follows: firstly, the bearing is pressed into the bearing hole, and the upper end face of the bearing is caused to subside 2 to 5 millimeters from the upper edge of the bearing hole; secondly, the bearing sleeve is covered by the conical sleeve, and the conical sleeve is downwards pressed so that the upper edge of the bearing sleeve can incline inwardly; and finally, a rotary centre shaft is arranged, a pin shaft which penetrates transversely is arranged on the lower end of the centre shaft, roller wheels are arranged on both ends of the pin shaft, the A-frame is arranged right under the centre shaft, the roller wheels are positioned on the edges of both sides of the bearing sleeve, and the centre shaft is downwards moved slowly so as to lead the roller wheels to continuously rotatably press the upper edge of the bearing sleeve until rotary riveting is accomplished. The method has the advantages of simple operation, low cost, high efficiency of rotary riveting and high percent of pass of processed products.

Description

Technical field: [0001] The invention mainly relates to a spin riveting method, in particular to a triangular bracket spin riveting method. Background technique: [0002] A triangular bracket is mainly used to connect the top of the shock absorber at the front end of the car to the car body, which plays the role of shock absorption, noise reduction and buffering, and can improve the driving comfort of the car. The technical requirements of this product are: the thickness of the metal skeleton after back riveting of the bearing is less than or equal to 1.7mm, and the flatness is within 0.3mm. At present, domestic rotary riveting equipment cannot meet the technical requirements of this product, while the price of foreign rotary riveting equipment is more than 500,000 yuan. Therefore, a new type of technology is urgently needed. Invention content: [0003] The purpose of the present invention is to make up for the defects of the prior art, and to provide a method for screw r...
