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 with reference to the drawings and embodiments.

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

[0031] (1) Positioning of the plate spring bracket to be sub-assembled: take the plate spring bracket 7 and place it on the sub-assembly table 10, and use the two support blocks 4 and a positioning clamping device 3 on the sub-assembly table 10 for positioning to ensure that the press assembly Accurate product positioning;

[0032] (2) Placement of leaf spring lugs and washer adjustment: Place the leaf spring lugs in the corresponding installation grooves of the leaf spring bracket 7, install a washer on both sides of the lugs to eliminate the gap, and adjust the leaf spring pin by using the leaf spring overshoot Through hole, make the washer, ear hole and bracket hole coaxial;

[0033] (3) Grease the leaf spring pin: apply lithium-based lubricant even...

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 heavy-duty automobile leaf spring pin pressing process and its pressing equipment. Background technique [0002] The plate spring of the heavy-duty vehicle is connected with the bracket through a plate spring pin. At present, the assembly method of the leaf spring pin adopts manual adjustment and assembly. The operator uses the overshoot to manually adjust when assembling the leaf spring pin, and uses the leaf spring overshoot to adjust the through hole of the leaf spring pin, 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 lifting lugs to connect the lifting lugs with the bracket. This assembly method is likely to cause high labor intensity in the assembly of the leaf spring pin, the assembly quality is difficult to guarantee, the efficiency is extremely low, and the copper hammer used for assembly is very easy to wear, frequently replaced, and the as...
