Description

Technical Field

[0001] The utility model belongs to the technical field of oil pump processing, and in particular relates to an oil pump assembly mechanism which is convenient to use. Background Art

[0002] The oil pump pressurizes the oil in the oil pan and sends it to the oil filter and various lubricating oil channels to lubricate the main moving parts of the engine and filter the oil. When the oil pump is produced and processed, the various components need to be assembled together.

[0003] Prior art CN220575784U discloses an oil pump assembly mechanism, comprising a base, two groups of side plates are symmetrically mounted on the upper end of the base, a clamping plate is arranged on the inner side of the side plate, a pushing piece for pushing the clamping plate to move is also arranged on the side plate, an elastic pushing plate is arranged between the two groups of side plates on the base, the pushing piece comprises a fixing frame mounted on the side plate, a screw rod is rotatably arranged on the fixing frame, and a sleeve threadedly connected to the screw rod is arranged on the side of the clamping plate;

[0004] The clamp of the assembly mechanism can achieve better results when clamping square workpieces, but the outer shell of the oil pump is usually irregular in shape. When the clamp is clamping the oil pump, there are fewer contact points and the clamping is unstable. For example, some oil pump outer shells are arc-shaped, and the contact point between the clamp and the oil pump housing is the tangent point between the clamp wall and the arc surface of the oil pump housing. Fewer contact points lead to poor clamping effect. Summary of the invention

[0018] 1. The utility model provides a clamping assembly. During the assembly of the oil pump, the oil pump housing is first placed on the base, and the rotating motor is started to move the two clamping plates toward each other, thereby making the push rod contact the oil pump housing. As the clamping plates continue to move, the guide column slides into the push rod, and at the same time compresses the spring 1, so that the ends of the push rods on both sides are tightly in contact with the oil pump housing. Due to the elastic force of the spring 1, different push rods can be extended to different lengths according to different shapes of the oil pump housing, thereby increasing the number of contact points between the push rod and the oil pump housing, and having a better clamping effect for the oil pump with an irregular housing, making the clamping more stable, thereby facilitating the assembly and processing of the oil pump, and being convenient and quick to use.

In the process of assembling the oil pump, the oil pump housing is first placed on the base 1, and the rotating motor 2 is started to make the two clamping plates 5 move toward each other, so that the push rod 601 contacts the oil pump housing, and as the splint 5 continues to move, the guide column 602 slides into the push rod 601 and compresses the spring 1 at the same time, so that the ends of the push rod 601 on both sides are tightly in contact with the oil pump housing, and due to the elastic force of the spring 1, different push rods 601 can be extended to different lengths according to the different shapes of the oil pump housing, thereby increasing the number of contact points between the push rod 601 and the oil pump housing, and having a better clamping effect for the oil pump with an irregular housing, making the clamping more stable.
