Description

Technical Field

[0001] This invention belongs to the field of engine oil pump cover manufacturing technology, specifically relating to a suspended conveying system and method for surface treatment of engine oil pump covers. Background Technology

[0002] The function of an automotive engine oil pump is to deliver engine oil to all friction points of the engine, allowing the oil to circulate in the lubrication circuit to ensure proper engine lubrication. Oil pumps are mostly gear pumps, consisting of a pump cover, pump housing, drive pump shaft, driven pump shaft, and gears mounted on the outside of the two pump shafts. The pump housing has an oil inlet and an outlet on each side. The oil pump cover is one of the important components of the automotive engine oil pump; its main function is to seal the pump body, providing isolation.

[0003] The primary function of surface anti-corrosion treatment on the engine oil pump cover is to significantly improve its durability and reliability, ensuring long-term stable engine operation. Since the oil pump cover is constantly exposed to the high-temperature, high-pressure environment of engine oil containing corrosive substances, anti-corrosion treatment effectively isolates the metal substrate from moisture, acidic substances, and oxidizing media, preventing rust and chemical corrosion. This treatment not only extends the service life of the oil pump cover itself but also avoids the risk of corrosion products contaminating the engine oil or damaging the sealing performance. Simultaneously, the anti-corrosion layer reduces material loss on the metal surface due to oxidation or electrochemical reactions, maintaining the dimensional stability and mechanical strength of the component, thereby ensuring the oil pump's sealing performance and operating efficiency. Furthermore, good anti-corrosion performance reduces the failure rate caused by corrosion, decreasing maintenance frequency and costs, and improving the overall economy and environmental friendliness of the engine. Through surface anti-corrosion treatment, the oil pump cover's resistance to aging under harsh operating conditions is enhanced, further optimizing the engine's long-term performance.

[0004] Existing engine oil pump covers suffer from poor sealing and are prone to significant wear on the drive and driven pump shafts. To address this, our company has designed an improved engine oil pump cover with a sealing convex edge, a drive pump shaft protector, and a driven pump shaft protector.

[0005] In the aforementioned improved anti-corrosion treatment of the engine oil pump cover surface, a suspended conveyor system is required for batch transfer. Existing suspended conveyor systems for engine oil pump cover surface treatment have several shortcomings: firstly, the clamping reliability during suspension is not ideal; the impact force of the spray gun can easily cause the hanger to sway and deflect, affecting the spraying effect; secondly, it cannot pre-install active and driven pump shaft guards on the pump cover component before spraying; and thirdly, it cannot pre-shape the sealing protrusions before spraying. Therefore, it is necessary to optimize and improve the existing suspended conveyor system for engine oil pump cover surface treatment. Summary of the Invention

The anti-corrosion liquid spraying assembly 8 is located near the spraying station and is used to perform anti-corrosion spraying treatment on the inner surface of the oil pump cover 9.

[0024] like Figures 2-3 As shown, this embodiment provides an improved oil pump cover 9, which is mainly composed of a pump cover component 91, a driving pump shaft protection component 92, and a driven pump shaft protection component 93.

[0025] like Figure 4 As shown, the pump cover component 91 includes a cover plate 911. The inner side of the cover plate 911 is provided with a sealing protrusion 912. The cover plate 911 is provided with a plurality of fastening holes 913 at equal intervals in the outer area of ​​the sealing protrusion 912.

A positioning slot 934 is provided in both the second protection end plate 931 and the second threaded post 932 to facilitate positioning and support of the driven pump shaft.

[0028] like Figure 8 As shown, the hanging clamping assembly 2 includes a horizontal beam plate 21, a horizontal rotation drive mechanism 22, a vertical frame 23, positioning cams 24, and a pump cover locking mechanism 25. One end of the horizontal beam plate 21 is fixedly connected to the corresponding slider on the annular guide rail pair 3. The other end of the horizontal beam plate drives the vertical frame 23 to rotate horizontally through the horizontal rotation drive mechanism 22. Each side frame of the vertical frame 23 is equipped with two positioning cams 24. Several pump cover locking mechanisms 25 are installed side by side between the two positioning cams 24 on the vertical frame 23.

[0029] like Figure 9 As shown, the horizontal rotation drive mechanism 22 includes a horizontal rotation drive motor 221, a bevel steering gear set, a suspension vertical shaft 223, and a gear box 222. The horizontal rotation drive motor 221 and the gear box 222 are installed on the upper side of the horizontal beam plate 21. The output shaft of the horizontal rotation drive motor 221 is connected to the upper end of the suspension vertical shaft 223 through the bevel steering gear set located in the gear box 222. The lower end of the suspension vertical shaft 223 is fixed with a vertical frame 23.

[0030] In this embodiment, the positioning cam 24 is located in the fastening holes 913 of the two outermost pump cover components 91, which cooperate with each other.

[0031] like Figure 10As shown, the pump cover locking mechanism 25 includes an inner support bracket 251, a first axial push rod 252, a first rotary joint 253, a first push shaft 254, a locking plate 255, a locking rod 256, a first tilting motor 257, a first anti-slip belt transmission component 258, and a support block 259. The inner support bracket 251 is installed inside the vertical frame 23. The first axial push rod 252 is symmetrically installed on the upper side of the inner support bracket 251. The movable end of the first axial push rod 252 is connected to one end of the first push shaft 254 via the first rotary joint 253.

The driven gear has a protruding key on the inner wall of the through hole.

[0032] The working principle of the hanging clamping assembly 2 is as follows: A robotic arm holds the pump cover component 91 against the outside of the vertical frame 23. The first flipping motor 257 in the pump cover locking mechanism 25 drives the locking plate 255 to flip from a horizontal to a vertical position. Then, the first axial push rod 252 drives the locking plate 255 and the locking rod 256 to move axially. The locking rod 256, together with the positioning cam 24, locks the pump cover components 91 on the same side. Then, the horizontal rotation drive mechanism 22 drives the vertical frame 23 to rotate horizontally by 180 degrees. The above steps are repeated to lock the pump cover components 91 on the other side. The hanging clamping assembly 2 provides stable clamping for the pump cover component 91.

[0033] like Figure 11 As shown, the first feeding component 4 and the second feeding component 5 have the same structure and are symmetrically arranged; as Figure 12 As shown, the first feeding component 4 includes a vertical storage box 41. The interior of the vertical storage box 41 is provided with a storage area 42 for storing the active pump shaft protector 92 or the driven pump shaft protector 93 side by side.

A first suction head 48 capable of adsorbing the active pump shaft protector 92 or the driven pump shaft protector 93 is installed on the movable end of the transverse feeding push rod 47.

[0034] The working principle of the first feeding assembly 4 is as follows: the transverse feeding pusher 47 pushes the first suction head 48 to move laterally, causing it to adsorb the bottommost active pump shaft protector 92. The longitudinal feeding pusher 45 pushes the active pump shaft protector 92 to the front of the protector mounting assembly 6 and feeds it with material. Then, the first suction head 48 and the transverse feeding pusher 47 are reset sequentially. After each feeding, the active pump shaft protector 92 is automatically replenished under gravity. Similarly, the second feeding assembly 5 is used to feed the driven pump shaft protector 93 into the protector mounting assembly 6.

[0036] like Figure 14 As shown, the first lead screw drive mechanism 62 includes a channel plate 621, a lead screw motor 622, a lead screw 623, and a guide rod 624. The lead screw motor 622 is mounted on the outer side of the channel plate 621, and the output end of the lead screw motor 622 is connected to the lead screw 623. The lead screw 623 is movably supported by the two side plates of the channel plate 621, and the guide rod 624 is fixed between the two side plates of the channel plate 621. The first carrier block 63 has a lead screw hole that mates with the lead screw 623 and a guide hole that mates with the guide rod 624.

[0037] like Figure 15 As shown, the first tilting and propulsion mechanism 64 includes a mounting frame 641, a second axial push rod 642, a second rotary joint 643, a second push shaft 644, a second tilting motor 645, and a second anti-slip belt drive component 646. The mounting frame 641 is fixed to the outside of the first carrier block 63. The second axial push rod 642 is installed inside the mounting frame 641. The movable end of the second axial push rod 642 is connected to one end of the second push shaft 644. A second suction head 65 is installed at the other end of the second push shaft 644. The second tilting motor 645 is fixed to the outside of the mounting frame 641. The output shaft of the second tilting motor 645 drives the second push shaft 644 to rotate circumferentially via the second anti-slip belt drive component 646. The structures of the second push shaft 644 and the second anti-slip belt drive component 646 are designed with reference to the structures of the first push shaft 254 and the first anti-slip belt drive component 258.

[0038] like Figure 16 As shown, the outer side of the second adsorption head 65 is provided with a slot for the active pump shaft guard 92 and the driven pump shaft guard 93 to be inserted.

[0039] The working principle of the protective component installation assembly 6 is as follows: The second suction head 65 receives the delivered active pump shaft protective component 92 or driven pump shaft protective component 93. The first vertical linear guide pair 61 drives the second suction head 65 to move vertically. The first lead screw drive mechanism 62 drives the second suction head 65 to move laterally. The first flipping and pushing mechanism 64 drives the second suction head 65 to flip circumferentially and move axially, thus meeting the installation requirements of the active pump shaft protective component 92 or driven pump shaft protective component 93.
