Abstract
The utility model relates to a fastening tool for non-standard bolts and nuts, which belongs to a tool fastening tool. The fastening tool for non-standard bolts and nuts is characterized in that a sleeve is arranged on a seamless steel pipe section; when a non-standard countersunk head bolt is fastened, the outer diameter of the sleeve is smaller than the diameter of a counter bore; a torque plate is welded at the bottom end of an inner cavity of the sleeve; a through hole corresponding to and consistent with the appearance of a non-standard bolt head or nut is formed at the center of the torque plate; a hole is formed on the upper end section of the sleeve in a sagittal symmetry or bilateral symmetry manner, and a torsion bar penetrates the hole; and when the fastening tool is used, the through hole on the torque plate is sleeved on a non-standard screw head or a non-standard nut, and the torsion bar is twisted with force, so that the sleeve drives the non-standard bolt or the non-standard nut to be rotatably fastened. The fastening tool has simple structure, can be reused, is convenient to use, easy for controlling the tightening torque and is low in manufacturing cost.
Description
Technical field
The utility model belongs to the bolted instrument, especially relates to a kind of non-standard bolt, nut fastened tools.
Background technology
At present, run into some non-standard screw bolt and nut through regular meeting in metallurgy construction, the spanner that does not often have correspondence at the scene can carry out fastening, or run into some dormant bolts with conventional spanner can't be fastening situation.Tend to make these non-standard bolts, nut not to reach fastening force, serious meeting influences the firmness of connected piece, causes certain unsafe factor for the use of later connector.
Summary of the invention
The purpose of this utility model provides a kind of non-standard bolt, nut fastened tools, improves the fastening quality and the dependability of non-standard bolt, nut effectively, further accomplishes safety in production.
The purpose of this utility model is achieved like this, a kind of non-standard bolt, the nut fastened tools, it is characterized in that: with the seamless steel pipe section is sleeve, when fastened when being off-gauge dormant bolt, the external diameter of this sleeve should be less than the diameter of counterbore, torsion plate is welded in the bottom of barrel bore, offer profile (as five sides) through hole corresponding to the same with non-standard bolt head or nut in the centre of this torsion plate, before and after on the upper end section wall of sleeve or left and right symmetrically perforate and in this hole, install torque arm, during use, through hole on the torsion plate (as five square holes) is entangled non-standard screw head or nonstandard nut, the push-jump torque arm of exerting oneself, make sleeve drive the rotation of nonstandard bolt or nut and fastening, the control of rotation external force, can on the screw bolt and nut of relative spinning, draw start line, calculate the anglec of rotation of bolted according to the diameter of bolt, by checking, the anglec of rotation of measuring nut is controlled the fastening force of this bolt.
The non-standard bolt that the utility model proposes, nut fastened tools, simple in structure, easy to use, Tightening moment is easy to control, and cost of manufacture is low, and is reusable.
Now in conjunction with the accompanying drawings and embodiments non-standard bolt, the nut fastened tools that the utility model proposed is further described.
Description of drawings
Fig. 1 is the non-standard bolt that proposes of the utility model, the main cross-sectional schematic of nut fastened tools.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Among Fig. 1, Fig. 2: 1, sleeve 2, torsion plate 3, torque arm
The specific embodiment
From Fig. 1, among Fig. 2 as can be seen: a kind of non-standard bolt, the nut fastened tools, it is characterized in that: with the seamless steel pipe section is sleeve 1, when fastened when being off-gauge dormant bolt, the external diameter of this sleeve 1 should be less than the diameter of this counterbore, torsion plate 2 is welded in the bottom of sleeve 1 inner chamber, offer profile (as five sides) through hole corresponding to the same with non-standard bolt head or nut in the centre of this torsion plate 2, before and after on the upper end section wall of sleeve 1 or left and right symmetrically perforate and in this hole, install torque arm 3, during use, through hole on the torsion plate 2 (as five square holes) is entangled non-standard screw head or nonstandard nut, the push-jump torque arm 3 of exerting oneself, make sleeve 1 drive nonstandard bolt or nut rotation and fastening, the control of rotation external force, can on the screw bolt and nut of relative spinning, draw start line, calculate the anglec of rotation of bolted according to the diameter of bolt, by checking, the anglec of rotation of measuring nut is controlled the fastening force of this bolt.
