Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of vehicle suspension spring code spraying, and particularly relates to a vehicle suspension spring code spraying system. BACKGROUND

[0002] Suspension springs are used on automobiles, are relatively heavy, and after length cutting, shot blasting and paint spraying operations, are conveyed to a code spraying position to spray product codes, and then can be shipped. The code spraying of suspension springs generally uses a plate type conveying chain, which is used in combination with a tray to place the suspension springs on the tray for code spraying. The conventional tray has a single function, cannot prevent adhesion or position fixing, cannot be adjusted, and cannot well adapt to the operation of suspension springs of various lengths.

[0003] The position between the conventional plate type conveying chain and the tray is fixed and cannot be adjusted, has a single function, and is limited in use. For example, a manual code spraying device for suspension springs disclosed in Chinese Patent Publication No. CN217455385U includes a rack, a limiting and pushing device, a code spraying head, and an adjusting and fixing frame. The limiting and pushing device is fixedly installed on the rack. The adjusting and fixing frame is fixedly installed on the rack. The code spraying head is fixedly installed on the adjusting and fixing frame. The limiting and pushing device includes an encoder, a manual pushing table, and a spring fixing mechanism. The manual pushing table is fixedly installed on the rack. The encoder is fixedly installed on the manual pushing table. The spring fixing mechanism is provided with a plurality of spring fixing mechanisms and is symmetrically arranged on the manual pushing table. The spring fixing mechanism is fixedly connected with the manual pushing table. The present application can effectively improve the speed and quality of manual code spraying. The position of the tray in this scheme is fixed and cannot be moved, which limits the length of the suspension spring and cannot well adapt to the code spraying of suspension springs of various sizes.

[0004] Therefore, it is necessary to invent a vehicle suspension spring code spraying system to solve the above problems. UTILITY MODEL CONTENTS

[0021] The working principle of the utility model is as follows:

[0022] Referring to the drawings in the specification Figures 1-3 , first, the suspension spring after cutting is subjected to the shot blasting operation, and then the elasticity index and the like are detected, the suspension spring that meets the standard is subjected to paint spraying (to prevent rust and be smooth and beautiful), and only the suspension spring after paint spraying is subjected to code spraying (to spray the product number, usually quick-drying powder spraying); the suspension spring after paint spraying is evenly placed in the code spraying tray 8 on the plurality of plate type conveying chains 7, due to the forward inclination of the code spraying tray 8, the excess paint or the waste on the suspension spring falls forward;
