Pipe fitting radial indexing drilling clamp tooling

Abstract

The invention relates to a pipe fitting radial indexing drilling clamp tooling, which relates to a clamp tooling of a pipe fitting excircle drilling work procedure and solves the problems that each connecting hole on the existing pipe fitting excircle is processed by boring and milling equipment and precise numerical control equipment, and the mass production requirements cannot be met. A drill bush is arranged in each drill bush hole arranged in an indexing disc, each screw rod hole arranged in the indexing disc is matched with one pressing screw rod, in addition, one end of the pressing screw rod is connected with the screw rod hole through screw threads, the other end of the pressing screw rod passes through a press plate to be connected with a pressing screw nut through screw threads, a positioning pin is arranged in a first positioning pin hole, a copper bush is arranged in a copper bush installing hole, a middle shaft is arranged in a middle shaft installing hole and an inner hole of the copper bush, a middle shaft at one end of the copper bush is connected with a screw nut through screw threads, a middle shaft of one end of a first flange is connected with a fastening handle through screw threads, a positioning screw and a positioning threaded hole are connected through screw threads, an indexing pin is embedded in a second positioning pin, and a position limiting pin is arranged in a first position limiting pin hole and a second position limiting pin hole. The clamp tooling is used for processing each hole on the excircle surface of pipe fittings.

Description

technical field

[0001] The invention relates to a fixture tooling for the outer circle drilling process of pipe fittings. Background technique

[0002] The connecting holes on the outer circle of the pipe fittings (with a wall thickness of 20 mm) require high precision distribution. The existing methods for processing the connecting holes on the outer circle of the pipe fittings are mostly processed by boring and milling equipment and precision numerical control equipment. Although boring and milling equipment can basically meet the positional accuracy requirements of each hole, additional steps such as clamping, alignment, and measurement in the process increase accordingly, which is time-consuming and laborious, and is not conducive to the normal progress of the entire production assembly. The use of precision numerical control equipment can better meet the position accuracy requirements of each hole, but its manufacturing cost is relatively high, which does not conform to...
