Embodiment Construction

[0026] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 3-4 As shown, the structure of this embodiment includes a base 1, a self-centering positioning mechanism, a first pressing mechanism and a second pressing mechanism. The self-centering positioning mechanism is arranged on the base 1 and includes two sets of oppositely arranged V Shaped positioning arms 6 are symmetrically distributed on the upper surface of the base 1, and each group of V-shaped positioning arms 6 can move toward or away from another group of V-shaped positioning arms 6, and the flange fork 4 is placed on two groups of V-shaped positioning arms 6. Between the V-shaped positioning arms 6, radial positioning is carried out by two groups of V-shaped positioning arms 6;

[0028] The first pressing mechanism 5 is arranged above the flange fork 4, and its lower surface is a V-shaped surface, which is used to cooperate...

Abstract

The invention provides a universal fixture for processing flange fork bolt holes, which can complete the multi-point automatic clamping and positioning of the flange fork at one time, effectively improving the efficiency of clamping and positioning. The technical solution of the invention includes a base, self-centering positioning mechanism, the first pressing mechanism and the second pressing mechanism, the self-centering positioning mechanism is arranged on the base, including two sets of V-shaped positioning arms arranged oppositely, distributed symmetrically on the upper surface of the base, and each set of V-shaped positioning arms The arms can all move towards or away from another set of V-shaped positioning arms, and the flange fork is placed between the two sets of V-shaped positioning arms, and is radially positioned by the two sets of V-shaped positioning arms; The clamping mechanism is arranged above the flange fork, and the second clamping mechanism has two groups, including an oil cylinder, a pressing rod, a connecting rod and an oil cylinder support.

Description

technical field [0001] The invention relates to the technical field of flange fork processing and clamping, in particular to a universal clamp for processing flange fork bolt holes. Background technique [0002] At present, the four holes of the flange fork drill are positioned by the end face teeth. The bolt holes are machined by a drill bit with face teeth on the drill sleeve. In the prior art, the clamping and positioning method of the flange fork is generally carried out by manual positioning, which cannot ensure that the center of the flange fork coincides with the center of the workbench, the accuracy of clamping and positioning is low, and multiple adjustments are required, resulting in the efficiency of clamping and positioning. Low. Contents of the invention [0003] The invention provides a universal fixture for processing flange fork bolt holes, which can complete multi-point automatic clamping and positioning of flange forks at one time, and effectively impro...
