The center part of the upper surface of the tool shell is provided with a waist-shaped hole, the length direction of the waist-shaped hole is parallel to the length direction of the tool shell, and the waist-shaped hole is used for an inner hexagonal wrench to pass through.
Optionally, the toothed plate is connected with the inner side surface of the trapezoidal clamping groove in a bonding or welding manner.
Optionally, the tooth angle of the serrations is less than 90 °.
Optionally, the width of the narrow side of the trapezoidal clamping groove is 5 mm, the width of the wide side of the trapezoidal clamping groove is 20 mm, and the depth of the trapezoidal clamping groove is 20 mm.
Optionally, the circular diameter of the kidney-shaped hole is 6 mm.
Optionally, the tooth plate has a width of 10 mm.
The application provides a high lock bolt extracting tool can improve the efficiency of workman on the high lock bolt is dismantled, goes to accomplish the dismantlement work with the shortest time, the most laborsaving method, the most effective means, the most economic instrument.
Drawings
FIG. 1 is a schematic structural view of a high lock bolt removal tool provided herein;
FIG. 2 is a schematic view of a tooth angle of a saw tooth provided herein;
FIG. 3 is a top view of a trapezoidal card slot provided herein;
fig. 4 is a cross-sectional view of a trapezoidal card slot provided in the present application.
Detailed Description
The application provides a high lock bolt extracting tool, as shown in fig. 1, includes: the tool housing 1 is provided with a tool housing,
the tool shell 1 is internally provided with a trapezoidal clamping groove, the trapezoidal clamping groove is used for adapting to bolt heads or nuts with different diameters, the inner side face of the trapezoidal clamping groove is provided with a toothed plate 2, a plurality of vertical sawteeth are arranged on the toothed plate 2, and the sawteeth are used for clamping the bolt heads or the nuts.
The central part of the upper surface of the tool shell is provided with a waist-shaped hole 3, the length direction of the waist-shaped hole 3 is parallel to the length direction of the tool shell 1, and the waist-shaped hole 3 is used for an internal hexagonal wrench to pass through.
Optionally, the pinion rack is independent part, and the pinion rack is connected with the medial surface of trapezoidal draw-in groove through bonding or welding form.
Alternatively, as shown in FIG. 2, the tooth angle of the serrations is less than 90.
The trapezoidal clamping groove can accommodate corresponding bolt heads of M4-M10 high-locking bolts or installed nuts. For example, as shown in fig. 3, the width a of the narrow side of the trapezoidal card slot may be 5 mm, and the width b of the wide side may be 20 mm.
Illustratively, as shown in FIG. 4, the depth e of the trapezoidal card slot is 20 millimeters.
The waist-shaped hole can be used by an internal hexagonal wrench suitable for installing M4-M10 high-locking bolts.
Illustratively, as shown in fig. 3, the circular radius c of the kidney-shaped hole is 3 mm.
The tooth plate width need only accommodate the bolt head or nut height.
Illustratively, as shown in fig. 4, the width d of the tooth plate is 10 millimeters.
The application provides a high lock bolt extracting tool, uses with interior hexagonal spanner is supporting during the use. When the tool is used, the tool is firstly sleeved at one end of a nut of a high-locking bolt, after the toothed plate is pushed to tightly press the nut, an inner hexagonal wrench is inserted into an inner hexagonal hole in the tail part of the bolt through a waist-shaped hole in a tool shell, the bolt body is fixed, and the nut is unscrewed until the nut is dismounted by rotating the tool.
Before improving, the workman when carrying out high-lock bolt dismantlement operation, the fixed bolt body of hexagonal spanner in using on the other hand, uses the pliers to press from both sides tightly and swivel nut decomposes on the other hand, because the clamp force of pliers needs the workman to apply by hand, the easy fatigue of operation, dismantles 1 high-lock bolt and uses time three minutes or even longer time about, wastes time and energy. After the tool is improved, the operation of workers is convenient and rapid, the time is up to one minute, and the working efficiency is greatly improved. In summary, the tool achieves the following results:
1. the radial clamping force forming mode required when the nut is rotated is changed, and workers can operate the nut more easily and labor-saving.
2. The time for disassembling the high-locking bolt is shortened from the first 3 minutes to less than 1 minute after improvement, and the production efficiency is greatly improved.
3. The clamping groove part of the shell is designed to be trapezoidal, so that the self-adaptive function is increased, the use universality of the tool is improved, the tool can be used for disassembling high-locking bolts, and the tools can be adopted for disassembling fasteners under other similar conditions.
4. Simple structure and low cost.
