Mounting clamp for high lock bolt and nut assembly

Abstract

The invention discloses a mounting clamp for a high lock bolt and nut assembly. The mounting clamp comprises an outer shaft (1), an inner shaft (2) and a reducing sleeve (3). The mounting clamp is characterized in that the outer shaft (1) separately sleeves the inner shaft (2), the reducing sleeve (3) sleeves a hexagonal prism at the front end of the inner shaft (2) through an inner hexagonal holein the tail end, a thread is arranged at the tail end of the inner shaft (2), a compression spring (4) is mounted between the reducing sleeve (3) and the inner shaft (2) and is placed in the reducingsleeve (3), a hexagonal wrench (5) is connected in a square hole in the front end of the reducing sleeve (3), the inner shaft (2) is mounted in the outer shaft (1) through a bearing (6) and a retainer ring (7), the bearing (6) and the retainer ring (7) are placed on the end portion of the outer shaft (1), and the hexagonal wrench (5) is welded into the square hole in the front end of the reducingsleeve (3). The mounting clamp disclosed by the invention is simple in structure, convenient to operate, stable and reliable and efficient and high in quality, and is suitable for being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of clamping devices, and in particular relates to a fixture for installing a high-lock bolt and nut assembly. Background technique [0002] Bolt and nut assemblies are very common in the daily production process, and in the aviation field, high-lock bolt and nut assemblies are indispensable. Ordinary bolts have hexagonal, twelve-angular or cross-recessed driving parts on the head. When installing ordinary bolts and nuts, the driving parts are on both sides of the interlayer, so the operation is more convenient. Some high-lock bolts have no wrenching device at the head, but an inner hexagonal hole at the tail. When the high-lock bolt and nut assembly are installed, the wrenching parts of the two are located on the same side of the interlayer, so equipment such as torsion testing machines cannot be used. , you must use a special gun tool to install. However, the existing special tools have disadvantages such...
