Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing.
[0015] like figure 1 , figure 2 As shown, a lock pin positioning suspension type front axle lock pin press machine includes a bow beam 1; an L-shaped positioning block 2 is fixedly connected to the upper part of the left extension arm of the bow beam 1 through a threaded connection, and the L-shaped positioning block 2 is fixed during installation. The horizontal end of the block 2 is fixedly connected to the arched beam through a threaded connection, and then tightened with a nut, and a V-shaped groove corresponding to the section of the wedge-shaped locking pin 10 is provided on the vertical end face of the L-shaped positioning block 2; The lower part of the left extension arm of the arched beam 1 is fixed with a first externally threaded single-acting hydraulic cylinder 3 (an externally threaded single-acting cylinder can also be used) through a threaded connection. T...

The invention provides a lock pin positioning suspension type front axle lock pin press-mount machine comprising an arched beam; an L-shape positioning block is arranged on the upper portion of an arched beam left extension arm; the lower portion of the arched beam left extension arm is provided with a first single acting cylinder or a first single acting hydraulic cylinder; the lower portion of an arched beam right extension arm is provided with a corresponding second single acting cylinder; the rear end of the cylinder body of the first single acting cylinder or the first single acting hydraulic cylinder is provided with a pedestal; the front end of the piston rod of the first single acting cylinder or the first single acting hydraulic cylinder is provided with a fast-change pressure head; the front end of the piston rod of the second single acting cylinder is provided with an initial pressure lining; the initial pressure lining and the fast-change pressure head are arranged on a same axis; the top of the arched beam is provided with a suspension ring; the lock pin positioning suspension type front axle lock pin press-mount machine can replace an original lock pin manual knocking mode, can reduce lock pin damages caused by artificial factors, thus reducing production cost, ensuring the lock pin to be pressed in proper depth, and improving assemble quality; the suspension type arrangement can reduce assemble wire occupation space, and operation is convenient and flexible, thus reducing laboring intensity, and improving work efficiency.
Description
technical field [0001] The invention relates to a press-fitting device for an automobile lock pin, in particular to a press-fitting machine used in the installation process of a wedge-shaped lock pin of an automobile front axle assembly. Background technique [0002] During the assembly process of the automobile front axle assembly, the wedge lock pin needs to be installed. At present, the assembly of the front axle assembly has realized the assembly line flow operation. There are several sets of flow circulation fixtures and several stations on each assembly line. When the assembly line is started, the fixtures start to circulate, and each station is completed under the fixed rhythm of the line body design. respective assembly actions. [0003] However, the existing lock pins of the front axle assembly are generally still installed by manual knocking, that is, the front axle assembly is fixed on the trolley on the loop line, and the lock pin is pressed as the trolley moves...
