Abstract
Flange boring grab, base center department is equipped with the dabber perpendicularly, lies in the dabber outside installation anchor clamps body on the base, and anchor clamps body upper portion is equipped with the anchor clamps body tang with flange shaft diameter complex, and the packing ring on flange upper portion passes through packing ring fix with screw in the dabber. According to the flange drilling clamp, the drill clamp is centered by the internal spline, is changed into shaft diameter centering and is positioned by the large end face of the flange, so that the shaft diameter centering of the flange drill clamp is realized, the problems that a broach is quickly worn, the size of an inner hole is quickly changed, and the inner hole centering clamp cannot be designed are solved, the drilling position degree is ensured, and the process requirements are met.
Description
Technical Field
The utility model relates to the technical field of clamps, in particular to a clamp for flange machining.
Background
Along with the rapid development of economy in China, the demand of engineering machinery products required by infrastructure construction is gradually increased, a power takeoff serves as a matched product of the engineering machinery, a flange is an important component of a power takeoff assembly, and the flange drilling fixture is structurally characterized in that an inner hole is an internal spline.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems of the traditional flange drilling clamp, the utility model provides a flange drilling clamp adopting outer diameter centering.
The technical scheme adopted by the utility model for realizing the purpose is as follows: flange boring grab, 1 center department of base is equipped with dabber 6 perpendicularly, lies in the dabber 6 outside installation on the base 1 and presss from both sides the body 8, presss from both sides 8 upper portions and is equipped with the body tang 12 of clamp with flange 9 shaft diameter complex, and the packing ring 4 on flange 9 upper portion is fixed in on the dabber 6 through packing ring screw 5.
The base 1 is located the anchor clamps body 8 outside and passes through sizing block screw 3 symmetry installation sizing block 2, and the big terminal surface of 2 upper end positions of sizing block corresponding flange 9.
The middle part of the base 1 is provided with a base spigot 11, the excircle of the clamp body 8 is matched and installed with the spigot of the base 1, and the clamp body 1 is fixed on the base 1 through a fixing screw 7.
The fixture body 1 is arranged on the flange 9 in a clearance fit mode in the axial diameter.
According to the flange drilling clamp, the drill clamp is centered by the internal spline, is changed into shaft diameter centering and is positioned by the large end face of the flange, so that the shaft diameter centering of the flange drill clamp is realized, the problems that a broach is quickly worn, the size of an inner hole is quickly changed, and the inner hole centering clamp cannot be designed are solved, the drilling position degree is ensured, and the process requirements are met.
Drawings
FIG. 1 is a front sectional view of the flange boring jig of the present invention.
In the figure: 1. the base, 2, parallels, 3, parallels screws, 4, washers, 5, washer screws, 6, mandrels, 7, fixing screws, 8, the fixture body, 9, the flange, 10, the base seam allowance, 11, the fixture body seam allowance.
Detailed Description
The flange drilling clamp structure is shown in figure 1, a mandrel 6 is vertically arranged at the center of a base 1, a clamp body 8 is arranged on the base 1 and positioned outside the mandrel 6, a base spigot 11 is arranged in the middle of the base 1, the outer circle of the clamp body 8 is matched with the spigot of the base 1, and the clamp body 1 is fixed on the base 1 through a fixing screw 7. The upper portion of the clamp body 8 is provided with a clamp body spigot 12 matched with the shaft diameter of the flange 9, the clamp body 1 is installed in a clearance fit mode in the shaft diameter of the flange 9, a gasket 4 on the upper portion of the flange 9 is fixed on the mandrel 6 through a gasket screw 5, a sizing block 2 is symmetrically installed on the base 1 on the outer side of the clamp body 8 through a sizing block screw 3, and the upper end position of the sizing block 2 corresponds to the large end face of the flange 9.
Base 1 connects on the workstation of drilling machine, and 8 excircles of the anchor clamps body cooperate with the tang of base 1, screws up with set screw 7, and 2 parallels are screwed up with parallels screw 3, and put into the anchor clamps body tang 12 of the anchor clamps body 8 with 9 footpaths of flange during the installation, support the flange terminal surface with parallels 2, then with packing ring 4 through 5 hold-down flange big terminal surfaces of packing ring screw, realize flange drill clamp footpath centering.
