Problems solved by technology

This assembly method is likely to cause high labor intensity in the assembly of leaf spring pins, difficulty in ensuring assembly quality, and extremely low efficiency. The copper hammer used for assembly is easily worn out, frequently replaced, and the assembly cost is high; when using the copper hammer, goggles must be worn to prevent Anti-copper shavings splash, hot and uncomfortable to wear in summer, affecting assembly

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] As shown in the figure: a heavy-duty automobile leaf spring pin press-fitting process, including the following steps:

[0031] (1) Positioning of the leaf spring bracket to be subassembled: take the leaf spring bracket 7 and place it on the subpackage table 10, and use two support blocks 4 and a positioning clamping device 3 on the subpackage table 10 for positioning to ensure that the Precise positioning of product parts;

[0032] (2) Placement of leaf spring lifting lug and adjustment of gasket: place the leaf spring lifting lug in the corresponding installation groove of the leaf spring bracket 7, install a washer on both sides of the lifting lug to eliminate the gap, and use the leaf spring overshoot to adjust the leaf spring pin Through the hole, make the washer, lug hole and bracket hole coaxial;

[0033] (3) Apply butter to the leaf spri...

Abstract

The invention discloses a press-mounting technology and equipment for a heavy duty automobile plate spring pin. The press-mounting technology comprises the steps that (1) a plate spring bracket to be sub-mounted is positioned; (2) plate spring lugs are placed, and gaskets are adjusted; (3) the plate spring pin is coated with consistent grease; (4) the plate spring pin is mounted in a pressed mode; (5) the plate spring pin is locked through a locking bolt; (6) a sub-mounting assembly is taken down. The press-mounting equipment comprises a sub-mounting table, hydraulic cylinders, a dust cover, a plate spring pin guide and a press-mounting device. According to the press-mounting technology and equipment, the plate spring pin can be mounted quickly and accurately, mounting efficiency is enhanced, workpiece quality after mounting is also improved, and the cost is further reduced.

Description

technical field [0001] The invention relates to a press-fitting process of a leaf spring pin of a heavy-duty automobile. Background technique [0002] The heavy-duty vehicle leaf spring is connected to the bracket by a leaf spring pin. At present, the assembly method of the leaf spring pin adopts manual adjustment assembly. The operator uses overshoot to manually adjust when assembling the leaf spring pin, and uses the leaf spring overshoot to adjust the leaf spring pin through hole so that the washer, the lug hole and the bracket hole are coaxial. Then use a copper hammer to install the spring pin into the inside of the lifting lug, so that the lifting lug and the bracket are connected together. This assembly method is likely to cause high labor intensity in the assembly of leaf spring pins, difficulty in ensuring assembly quality, and extremely low efficiency. The copper hammer used for assembly is easily worn out, frequently replaced, and the assembly cost is high; goggl...
