Methods of using the fabrication system are also described.

A method and apparatus for processing workpieces to form parts. Tools associated with a multi-spindle machine may be positioned with respect to a plurality of workpieces on a fixture comprising a plurality of platforms and an adjustment system. Each platform may be individually moveable with respect to others in the plurality of platforms about a number of axes. The plurality of platforms may be configured to hold the plurality of workpieces in which each platform may be configured to hold a workpiece in the plurality of workpieces during operations performed by the multi-spindle machine. The adjustment system may be configured to move each of the plurality of platforms about the number of axes independently from the others in the plurality of platforms. The operations may be performed on the plurality of workpieces using the multi-spindle machine and the fixture to form a plurality of parts.

A high-precision two-part flat chuck device includes: a base, a cylinder, a sliding plate, a first clamping plate and a second clamping pate. A piston rod of the cylinder is connected with the sliding plate. Precision sliding rails are arranged at two sides of the base, and two sides of the sliding plate are respectively matched with the precision sliding rails in a sliding manner. An accommodating groove is arranged in a middle part of the sliding plate. The first and second clamping plates are symmetrically distributed in the accommodating groove along a center of the sliding plate, and a spring is arranged between the first and second clamping plates. Side surfaces of the first and second clamping plates are inclined planes, and chucks matched with each other are arranged at end parts of the first and seconding clamp plates.

The present disclosure belongs to the technical field of tools for bridge reinforcement, and particularly relates to a precisely-positioned drilling apparatus for steel tubular joints. According to the present disclosure, a lifting frame unit, an electric drill, a lever unit, a positioning tube unit, and a diagonal tensioning member unit are arranged on a base unit such that 1. during drilling, a drill rod is not prone to deviation, and a drilling action is relatively precise, resulting in an approximately circular shape of a final drilled hole; and 2. the above lever unit is essentially a labor-saving lever that ensures relatively easy and convenient drilling operations. Additionally, the present disclosure further discloses an application method of the apparatus, which ensures that the apparatus may stably fit with and be safely available for electric drills with various sizes and specifications.

An automated apparatus for use in selectively installing temporary fasteners in an assembly is provided. The apparatus includes an end effector, a cutting mechanism coupled to the end effector and that forms an opening in the assembly when a potential opening location is substantially aligned with a cutting mechanism center point. The apparatus also includes at least one of a first sub-assembly and a second sub-assembly coupled to the end effector. The first sub-assembly includes a temporary fastener insertion mechanism that inserts a temporary fastener through the opening in the assembly when the opening is substantially aligned with an insertion mechanism center point different from the cutting mechanism center point. The second sub-assembly includes a temporary fastener removal mechanism that removes installed temporary fasteners from the assembly when the installed temporary fastener is substantially aligned with a removal mechanism center point different from the cutting mechanism center point.
