Machining method of front connecting seat of five-degree-of-freedom steering mechanism and front connecting seat

Abstract

The invention discloses a machining method of a front connecting seat of a five-degree-of-freedom steering mechanism and the front connecting seat. The machining method comprises the two steps of S1, lineation positioning; and S2, machining and forming, wherein a positioning clamp is used for clamping and positioning. The front connecting seat comprises a connecting seat body, a first cantilever, an extending cantilever, a second cantilever, a third cantilever, a cover seat and a cover. The positioning clamp is used for one-time clamping, the situation that the cantilever state happens the front connecting seat in the machining process is avoided, the problem that due to the cantilevers, the strength is insufficient, vibration is generated, and deformation is caused or precision cannot be guaranteed is solved, the requirements for form and location tolerance and dimensional accuracy of machined parts are guaranteed, due to contact type limiting, no stress is released when a locking clamp is dismounted, and parts cannot deform.

Description

technical field [0001] The invention relates to a processing method of a front connecting seat of a five-degree-of-freedom steering mechanism and the front connecting seat, and belongs to the technical field of the connecting seat and the processing method of the connecting seat. Background technique [0002] In an all-terrain vehicle that can be used in complex environments such as water and land, the steering mechanism between two parts or two assemblies of the all-terrain vehicle needs to use the front connecting seat. For the front connecting seat, the front connecting seat structure Such as figure 1 As shown, there are the following difficulties in its processing: 1. The part is casted from a blank. In its structural form, there are many cantilever parts, and the parallelism and coaxiality of the cantilever in the same direction require high precision. During processing, vibration occurs due to insufficient strength and deformation Or the accuracy cannot be guaranteed;...

[0002] In an all-terrain vehicle that can be used in complex environments such as water and land, the steering mechanism between two parts or two assemblies of the all-terrain vehicle needs to use the front connecting seat. For the front connecting seat, the front connecting seat structure like figure 1 As shown, there are the following difficulties in its processing: 1. The part is casted from a blank. In its structural form, there are many cantilever parts, and the parallelism and coaxiality of the cantilever in the same direction require high precision. During processing, vibration occurs due to insufficient strength and deformation Or the accuracy cannot be guaranteed; 2. Secondary processing is required in all directions of X, Y, and Z after the blank is cast. Tight fixture stress releases, resulting in deformation
