Embodiment 1

[0050] First of all, it should be noted that the equipment disclosed in this embodiment is applied to the assembly and production of the oil delivery pump 3-5, and the implementation object of this embodiment is the oil delivery pump 3-5 in the assembly process, which specifically includes the pump head 3 -5-1 and the pump body, this embodiment will realize the connection between the pump head 3-5-1 and the pump body.

[0051] Please refer to Figure 6 ~ Figure 8 , this embodiment discloses an indexing mechanism for oil pump assembly, including an indexing plate 3-1, a first plate sleeve 3-2, a clamping seat 3-7, a second plate sleeve, and a second plate sleeve sliding sleeve Connected in the first plate cover 3-2, the first plate cover 3-2 can reciprocate along the extension direction of the second plate cover, and the second plate cover can fix the pump head 3-5-1 of the oil delivery pump 3-5 ;

[0052] Among them, please refer to Image 6 , the indexing plate 3-1 is a ci...

Embodiment 2

[0064] Please refer to Figure 1 to Figure 9 , this embodiment discloses an oil delivery pump tightening machine, comprising a workbench 5, a first tightening assembly 1, a second tightening assembly 4 and an indexing mechanism 3 for assembling an oil delivery pump as disclosed in Embodiment 1, and the workbench 5 is installed There is an indexing mechanism 3, the first tightening assembly 1 and the second tightening assembly 4 are installed on the workbench 5, and the movement direction of the actuator of the first tightening assembly 1 and the actuator of the second tightening assembly 4 are perpendicular to each other; the first tightening assembly The executive sub-mechanism of component 1 can be socketed in the horizontal direction of the oil pump 3-5 to be tightened, and the executive sub-mechanism of the second tightening assembly 4 can be socketed in the vertical direction of the oil pump 3-5 to be tightened. the bolt;

[0065] When the indexing mechanism 3 rotates, t...

Embodiment 3

[0081] Embodiment 3 discloses a fuel pump assembly method based on Embodiment 2, comprising the following steps:

[0082] First install the second plate sleeve and the first plate sleeve 3-2 on the pump head 3-5-1 respectively, and then complete the positioning of the first plate sleeve 3-2 and the second plate sleeve through the cylindrical positioning pin 3-4 , and then install the pump head 3-5-1 in the workpiece matching seat, and fix it with straight pins. After completing the tooling assembly of the oil pump 3-5, install it on the indexing plate 3-1;

[0083] Start the tightening mechanism. First, the cylinder in the second tightening assembly 4 controls the tightening shaft to descend, and the bolt on the upper end of the oil delivery pump 3-5 (that is, the vertical bolt of the oil delivery pump 3-5) is passed through the third outer hexagonal sleeve 4-4. Cooperate to realize the fixation of the oil delivery pump 3-5, the first cylinder 1-5 drives the first tightening a...

Abstract

The invention discloses an indexing mechanism for assembling a fuel delivery pump, a fuel delivery pump tightening machine and a fuel delivery pump assembling method. The fuel delivery pump tighteningmachine comprises a worktable, a first tightening assembly, a second tightening assembly and the indexing mechanism for assembling the fuel delivery pump, in any of claims 1 to 5 in the embodiment, wherein the worktable is provided with the indexing mechanism; the first tightening assembly and the second tightening assembly are both arranged on the worktable; the moving direction of an executingmechanism of the first tightening assembly is perpendicular to that of an executing mechanism of the second tightening assembly; an execution sub-mechanism of the first tightening assembly can be sheathed on a bolt in the horizontal direction of the fuel delivery pump of a to-be-tightened bolt; an execution sub-mechanism of the second tightening assembly can be sheathed on a bolt in the vertical direction of the fuel delivery pump of the to-be-tightened bolt; and when the indexing mechanism rotates, the first tightening assembly can be sheathed with each first plate bush of the indexing mechanism. According to the fuel delivery pump tightening machine, on the premise of ensuring the tightening precision, labor intensity of assembling work of the fuel delivery pump is reduced and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of assembly of oil delivery pumps, in particular to an indexing mechanism for assembling an oil delivery pump, a tightening machine for an oil delivery pump and an assembly method for an oil delivery pump. Background technique [0002] The role of the fuel delivery pump is to deliver the diesel in the fuel tank to the fuel injection pump. By ensuring the fuel volume and maintaining a certain fuel supply pressure to overcome the resistance of the pipeline and fuel filter, the diesel circulates in the low-pressure pipeline. With the development of diesel engine technology in our country, the demand for fuel pump as one of the important components of diesel engine is increasing, and the quality requirements for thread assembly are also getting higher and higher. Especially when the oil delivery pump body and the oil delivery pump head are assembled, because the front end structure of the oil delivery pump head is a cylin...
