[0001] The utility model relates to the technical field of suspension spring outer surface treatment, in particular to an outer surface treatment device for suspension spring production. Background Art

[0002] Automobile suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel). The main function of the suspension is to transfer the vertical reaction force (support force), longitudinal reaction force (driving force and braking force) and lateral reaction force of the road surface on the wheel and the torque formed by these reaction forces to the frame (or load-bearing body) to ensure the normal driving of the car. The automobile suspension spring is an elastic element in the automobile suspension, which makes the axle and the frame or body elastically connected, bears and transmits vertical loads, and alleviates and suppresses the impact caused by uneven roads.

[0003] When processing the suspension spring, the existing outer surface treatment device for suspension spring production usually clamps the suspension spring and uses a spray treatment device to spray the outer surface of the suspension spring. However, the clamping part usually misses the spray treatment, resulting in uneven treatment of the outer surface of the suspension spring, which reduces the practicality of the device. Therefore, there is an urgent need for an outer surface treatment device for suspension spring production to solve the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The outer surface treatment device for suspension spring production is provided with a treatment structure. When the outer surface of the suspension spring is sprayed, the pull rod is pulled to drive the moving rod to move in a direction away from the middle position of the clamping part, thereby driving the clamping plate to move synchronously, and then one end of the suspension spring is inserted into the inside of the clamping part so that it is clamped by two sets of clamping plates. Then, the outer surface spray treatment device is used to treat the suspension spring exposed outside the clamping part. When the outer surface treatment of the suspension spring exposed outside is completed, the hydraulic cylinder on the left is started to send the processed part of the right end of the suspension spring to the inside of the clamping part set on the right.

At the same time, the second servo motor is started to drive the threaded rod to rotate. Under the action of the thread, the screw sleeve is driven to move, and then the nozzle is driven to reciprocate to treat the outer surface of the suspension spring. Through this design, the outer surface treatment device for suspension spring production can perform reciprocating outer surface treatment on the suspension spring, with higher treatment efficiency, which improves the practicability and convenience of the device.
