Technical Field

[0001] The utility model belongs to the technical field of finished product processing of engine connecting rods, and particularly relates to an anti-rust oil coating device for engine connecting rod finished products. Background Art

[0002] The engine connecting rod is a key component in an internal combustion engine, and its function is to convert the reciprocating motion of the piston into the rotary motion of the crankshaft. The connecting rod connects the piston and the crankshaft and is an important link in the engine power transmission process. The design and manufacture of the connecting rod need to be very precise to ensure the smooth operation and long life of the engine. The weight, strength, stiffness, and balance of the connecting rod are all important factors to be considered in the design.

[0003] When the engine connecting rod leaves the factory, it needs to be coated with anti-rust oil to prevent rusting during storage and transportation. The existing anti-rust oil coating facilities are prone to causing anti-rust oil splashing during coating, polluting the surrounding facilities, and at the same time, this part of the anti-rust oil is difficult to recover and is prone to waste; at the same time, the excess anti-rust oil on the engine connecting rod after spraying is prone to dripping, affecting subsequent processing.

[0010] Furthermore, the pulley is hingedly connected to the lifting plate, and the lifting plate is slidably connected to the support plate.

[0011] Furthermore, the fixing plate is welded to the support plate, and the towing rope passes through the fixing plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The liquid pump extracts the antirust oil in the storage tank and sends it into the nozzles on the processing cylinder through the corrugated pipe. Finally, the nozzles distributed in a circumferential manner spray the antirust oil on the engine connecting rod, completing the antirust oil coating process. The processing cylinder blocks the splashing antirust oil, preventing it from polluting the facilities around the device. At the same time, the antirust oil on the inner wall of the processing cylinder flows down and finally falls into the collection tank. Through the design of the two-piece processing cylinder wrapping the engine connecting rod and cooperating with the bottom collection tank, the splashing of the sprayed antirust oil is prevented, making the processing site cleaner. At the same time, the redundant antirust oil is fully recovered, avoiding waste of raw materials and improving the processing economy.

[0014] 2. After the spraying is completed, the support plate supports the second motor to drive the cam to rotate. The cam intermittently pushes the pulley and the lifting plate to move downward. At the same time, the fixing plate supports the spring to repeatedly push the lifting plate upward through elastic force. During this process, the lifting plate vibrates up and down. Through the towing rope and the hook, the engine connecting rod is driven to vibrate up and down, so that the antirust oil beads about to drip on the engine connecting rod drip during the vibration. While achieving a film covering on the surface of the engine connecting rod, the local antirust oil does not accumulate excessively, making the antirust oil amount on the surface of the engine connecting rod in a moderate state. At the same time, the redundant falling antirust oil also falls into the collection tank, further improving the standardization and reliability of the device processing. Description of the Drawings

A spring 306 is fixedly arranged at the bottom of the lifting plate 305. A fixed plate 307 is fixedly arranged at the bottom end of the spring 306. A towing rope 308 is arranged in the middle of the lifting plate 305. A hook 309 is arranged at the bottom end of the towing rope 308. The pulley 304 is hinge-connected to the lifting plate 305.

The liquid pump 202 extracts the antirust oil in the storage tank 201 and sends it into the nozzles 205 on the processing cylinder 204 through the corrugated pipe 203. Finally, the circumferentially distributed nozzles 205 spray the antirust oil on the engine connecting rod to complete the antirust oil coating process. The processing cylinder 204 blocks the splashing antirust oil to prevent it from contaminating the facilities around the device. At the same time, the antirust oil on the inner wall of the processing cylinder 204 flows down and finally falls into the collection tank 206. Through the design of using the two-piece processing cylinder 204 to wrap the engine connecting rod, combined with the bottom collection tank 206, it prevents the sprayed antirust oil from splashing, makes the processing site cleaner, and at the same time fully recovers the excess antirust oil, avoids waste of raw materials, and improves the processing economy. After the spraying is completed, the support plate 301 supports the second motor 303 to drive the cam 302 to rotate. The cam 302 intermittently pushes the pulley 304 and the lifting plate 305 to move downward. At the same time, the fixed plate 307 supports the spring 306 to repeatedly push the lifting plate 305 upward by elastic force. During this process, the lifting plate 305 vibrates up and down, driving the engine connecting rod to vibrate up and down through the traction rope 308 and the hook 309, so that the antirust oil beads about to drip on the engine connecting rod drip during the vibration, realizing that while the surface of the engine connecting rod is covered with an oil film, the local antirust oil does not accumulate excessively, making the amount of antirust oil on the surface of the engine connecting rod in a moderate state. At the same time, the falling excess antirust oil also falls into the collection tank 206, further improving the standardization and reliability of the device processing.
