Problems solved by technology

1. Due to the general weight of the crankshaft, it is relatively labor-intensive for the workers to move the crankshaft back and forth during work; 2. Due to manual percussion, the positioning is not accurate enough, and there is a risk that the steel ball will be knocked out and hurt people; Knocking, the force of each knocking will have a large deviation, so the depth of steel ball pressing is inconsistent, resulting in inconsistent micro-deformation of the crankshaft, and the process consistency will be poor

Embodiment

[0037] This embodiment provides a steel ball pressing device 100, refer to figure 1 As shown, it includes a ram assembly 110 , a power unit 120 , a conversion mechanism 130 and a frame 140 .

[0038] Among them, such as figure 2 As shown in and 3 , the press head assembly 110 includes a press rod 111 , a riveting rod 112 and a base 113 . The base 113 is provided with a press-fit rod barrel 1131 for accommodating the press-fit rod 111 , the press-fit rod barrel 1131 is fixedly connected with the base 113 and penetrates through the base 113 . The press-fit rod 1131 is formed with a first accommodating cavity 1131a that runs through both ends of the press-fit rod 1131, and the press-fit rod 111 is movably embedded in the first accommodating cavity 1131a, and can move along the axial direction of the press-fit rod 1131. slide. In this embodiment, the press rod 111 has a first force-receiving end 1111 for contacting the power device 120 , and a first force-applying end 1112 for c...

Abstract

The invention provides a steel ball pressing device and crankshaft production equipment and relates to the field of engines. The steel ball pressing device comprises a pressing head assembly and a power device, wherein the pressing head assembly comprises a pressing rod used for pressing a steel ball into a crankshaft oil hole and a riveting rod used for pressing a rivet into the crankshaft oil hole, wherein the pressing rod and the riveting rod are arranged side by side; and the power device comprises a piston rod used for pushing the pressing rod or the riveting rod, and the piston rod can be driven by a switching mechanism to selectively act on the pressing rod or the riveting rod so as to realize the accurate and rapid switching of a steel ball pressing procedure and an oil hole blocking procedure. Besides, the steel ball pressing device well avoids the problems of low processing precision, poor technical reproducibility and the like, occurring in the manual processing process by using the power device to provide pressing power. The crankshaft production equipment comprising the steel ball pressing device can well keep technical consistency and can produce high-quality crankshafts in a high-reproductive manner.

Description

technical field [0001] The invention relates to the field of engines, in particular to a steel ball pressing device and crankshaft production equipment. Background technique [0002] In today's society, as people's economic conditions are getting better and better, cars have become standard equipment for middle-class families, and the sales of the auto industry are also increasing year by year. There are thousands of parts that make up a car. The engine is the core component of a car, and the crankshaft is It is an indispensable part of the engine composition. [0003] As the production of cars increases, the demand for crankshafts will increase accordingly. Because existing automobile manufacturer and crankshaft professional supplier all adopt the method for manual percussion to finish crankshaft lubricating oil hole plugging at present. There are several disadvantages of manual tapping method. 1. Due to the general weight of the crankshaft, it is relatively labor-intens...
