Embodiment 1

[0032] Embodiment of the present invention as a basic embodiment, the present invention includes a special tool for disassembly clamp narrow space, the sleeve 3 comprises a ratchet and the ratchet 4. One end of the ratchet sleeve 3 and 4 in contact with the ratchet wheel is cylindrical, inner side facing the square hole, one end close to the clamp 2 contracts inwardly to form a conical tapering section 7. The longitudinal contraction of the working section 7 lowest height than the minimum height of 5 theoretical high 0.5mm, the height of the minimum theoretical interference flanges body structure 1 at a position in height relative to the theoretical surface of the upper surface 2 clamps. 4 the ratchet sleeve 3 for screwing the actuating ratchet, the ratchet 4 is L-shaped, one end in contact with the ratchet 3 is the positive square prism sleeve. 4 plus four ratchet ratchet prism 4 in contact with the square holes in the sleeve and the sleeve is connected through.

Embodiment 2

[0034] As a preferred embodiment of the present invention, the present invention includes a dedicated tool in a narrow space for detachably clamp, comprising a ratchet sleeve 3 and the ratchet 4. One end of the ratchet sleeve 3 and 4 in contact with the ratchet wheel is cylindrical, inner side facing the square hole, one end close to the clamp 2 contracts inwardly to form a conical tapering section 7. The longitudinal shrinkage minimum operating section 7 is higher than the lowest height of 5 theoretical height 1.5mm, the height of the minimum theoretical interference flanges body structure at a position on a surface with respect to the theoretical level of the upper surface of the clip 2. 4 the ratchet sleeve 3 for screwing the actuating ratchet, the ratchet 4 is L-shaped, one end in contact with the ratchet 3 is the positive square prism sleeve. 4 plus four ratchet ratchet prism 4 in contact with the square holes in the sleeve and the sleeve is connected through.

Embodiment 3

[0042] As another preferred embodiment of the present invention, referring to the instruction manual figure 1The present invention includes a special tool for disassembling the clipper in a narrow space, including a ratchet sleeve 3 and a ratchet 4. One end of the ratchet sleeve 3 and the ratchet 4 is a cylindrical shape, and the end faces the inner four-square well, and is contracted inwardly near one end of the clamp 2 to form a tapered shrinkage section 7. The longitudinal minimum operating height 5 of the shrinkage segment 7 is 1 mm higher than the theoretical minimum height, the theoretical minimum height is the theoretical height of the upper surface of the upper surface of the body structural edge 1 relative to the clip 2 at the upper surface of the interference position. The ratchet 4 is used to twist the ratchet sleeve 3, the ratchet 4 being L-shaped, one end of the ratchet sleeve 3 is a positive quadrature column. The ratchet 4 is in contact with the inner four-square we...

Abstract

The invention relates to the technical field of mechanical processing, in particular to a special tool for disassembling and assembling clamps in a narrow space and a processing method thereof, including a ratchet sleeve and a ratchet, one end of the ratchet sleeve is connected with the ratchet, and the other end shrinks inward , forming a tapered contraction section; the longitudinal minimum working height of the contraction section is 0.5-1.5mm higher than the theoretical minimum height; by using the modeling method, the ratchet sleeve is measured in the model when it interferes with the body structure in a narrow space According to the size of the pressure, the structure of the contact surface between the ratchet sleeve and the structural interference extrusion is redesigned, and then the newly designed special tool is verified for the disassembly and assembly of the clamp on the machine, and the size and the structural shape of the working surface are fine-tuned. The special tool and the processing method thereof can effectively solve the problems of body structure damage, ratchet sleeve wear and time-consuming and labor-intensive problems caused by disassembling and assembling nuts in a narrow space.

Description

Technical field [0001] The present invention relates to the field of machining technology, and particularly relates to a method for processing a special tool for disassembly clamp in a small space. Background technique [0002] Use Ratchet attachment brackets are fixed military industry a common way, Ratchet has been widely used in various mechanical manufacturing and maintenance areas. Aircraft grid system and piping systems found throughout the whole machine, as a support clamp and a wire harness segment of the catheter is an important component of the machine is fixed. Common removably detachable by using ratchet socket cap screws, to tighten or remove the clamp to the clamp body tab. [0003] The above program can cause the following problems: [0004] When part of the body due to the narrow space and the error factor ear clip manufacture, assembly, resulting in the clamp screw hole from the center of the body structure often appear ratchet sleeve an outer diameter less than ...
