Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive chassis spring technology, specifically to an automotive chassis spring surface treatment device. Background Technology
[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. After the spring is manufactured, the factory will use a spraying device to spray the surface of the spring in order to improve the service life of the spring.
[0003] In the existing technology, when spraying the entire spring, it is often necessary to adjust the angle of the spring clamp multiple times, which not only results in insufficient uniformity of spring spraying, but also leads to low efficiency of spring spraying. Therefore, we have introduced a surface treatment device for automotive chassis springs. Utility Model Content
[0004] The purpose of this invention is to provide a surface treatment device for automotive chassis springs, which can perform reciprocating and uniform spraying on the entire spring, thereby improving the efficiency and uniformity of spraying and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A surface treatment device for automotive chassis springs includes a base, a fixed cover fixedly mounted on the upper end of the base, an opening on the front side of the fixed cover, electric push rods fixedly mounted on both inner walls of the fixed cover, a limiting block fixedly mounted on the output end of the electric push rod, a hollow ring between the two limiting blocks, a plurality of spray nozzles evenly mounted on the inner side of the hollow ring, a spray pipe mounted on one side of the hollow ring, a reciprocating moving mechanism mounted on the upper end of the hollow ring, and a sliding mechanism mounted on the lower end of the hollow ring.
[0007] As a further embodiment of this utility model, the reciprocating moving mechanism includes a motor, which is fixedly installed inside the fixed cover. A turntable is fixedly installed at the output end of the motor. A vertical strip frame is provided on the front side of the turntable. A guide post is slidably installed inside the strip frame. One end of the guide post is fixedly connected to the edge of the turntable.
[0008] As a further embodiment of this utility model, the sliding mechanism includes a slide rod, the top of the base is provided with a strip groove, the slide rod is fixedly disposed inside the strip groove, a slider is slidably disposed on the wall of the slide rod, and the upper end of the slider is fixedly connected to a hollow ring.
[0009] As a further embodiment of this utility model, a circular block is fixedly provided at the end of the guide post away from the turntable.
[0010] As a further embodiment of this invention, the diameter of the circular block is larger than the diameter of the guide post.
[0011] As a further embodiment of this invention, the limiting block is configured as a conical block.
[0012] As a further embodiment of this invention, the nozzle is configured as an atomizing nozzle.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This automotive chassis spring surface treatment device comprises a base, hollow ring, turntable, limiting block, fixing cover, spray pipe, electric push rod, circular block, guide post, strip frame, motor, slide rod, slider, and nozzles. When the external spraying device is activated, the spraying device drives the spray liquid through the spray pipe and multiple nozzles to uniformly spray the spring. The spring is placed horizontally within the hollow ring. Activating the electric push rod causes its output end to push the limiting block, which in turn presses and limits the spring's ends. Activating the motor causes its output end to rotate, driving the turntable to rotate. The turntable then rotates the guide post, which slides up and down within the strip frame, simultaneously causing the strip frame to move left and right. The strip frame, through the hollow ring, drives the slider to slide on the slide rod. Multiple nozzles can reciprocate and uniformly spray the entire spring, improving both spraying efficiency and uniformity. Attached Figure Description
