Abstract
The core-embedded steel wedge comprises an outer wedge and a core wedge, wherein the outer wedge is folded into a shape smaller than the outer wedge by using a steel plate with good toughness, the upper inclined plane of the outer wedge is made into a step, the upper inclined plane of the outer wedge rises in a step manner, a U-shaped groove is formed in the central line of the upper surface and the lower surface of the outer wedge, the U-shaped groove is as long as one half of the uppermost step, the width of the U-shaped notch is selected according to the diameter of a bolt, and anti-slip particles are arranged on the step plane of the outer wedge; the core wedge is made of a steel block, the upper plane and the lower plane of the core wedge are rough, the plane of the core wedge is provided with a U-shaped groove, the length and the width of the U-shaped groove of the core wedge are the same as those of the U-shaped groove of the outer wedge, the defect that the steel wedge is directly rubbed with a machine part when being knocked tightly is avoided, and therefore the purposes that the machine part is not damaged and a bolt is fastened when the steel wedge is knocked tightly are achieved.
Description
Technical Field
The utility model relates to a machine tool, specifically speaking are embedded steel wedge.
Background
In the daily mechanical emergency repair work, the bolt sometimes collides with the dead angle of a machine or the corner of a pipeline, due to corrosion or other reasons, a nut on the bolt cannot be screwed down temporarily, and the bolt cannot be dismounted and screwed down because the convolution margin is too small to cut, and the screw cannot be screwed down, so that great troubles are brought to the emergency repair work. Although the existing steel wedge (patent number: 200820179441.2) can prevent sliding, the step of the steel wedge is pressed against another part of the machine when the steel wedge is wedged, so that the steel wedge not only does not play a role in fastening, but also can hurt the other part.
Disclosure of Invention
In order to solve the problem that the steel wedge can damage other parts when being wedged (patent No. 200820179441.2), the utility model provides a steel wedge with embedded core, which can fasten the bolt which can not be folded down and can not damage other parts.
The technical measure adopted by the utility model for solving the technical problem is that the core-embedded steel wedge comprises an outer wedge and a core wedge, the outer wedge is folded into a shape smaller than the steel plate with good toughness, the upper inclined plane of the outer wedge is made into a step shape, the upper inclined plane of the outer wedge is made into a step ascending, a U-shaped groove is arranged on the central line below the outer wedge, the U-shaped groove is long to the half part of the uppermost step, the width of the U-shaped notch is selected according to the diameter of the bolt, and anti-slip particles are arranged on the stepped plane of the outer wedge; the core wedge is made of a steel block, the upper plane and the lower plane of the core wedge are rough, a U-shaped groove is formed in the plane of the core wedge, and the length and the width of the U-shaped groove are the same as those of the U-shaped groove of the outer wedge. When the steel wedge is used, the outer wedge is inserted between the loosened nut and the machine part, the lower plane of the nut is placed on the step plane with proper height, the screw rod is embedded into the notch of the outer wedge, the core wedge is inserted into the opening of the outer wedge and can be tightly knocked by force, so that the outer wedge expands to fasten the machine part, and when the steel wedge is knocked tightly, friction occurs between the core wedge and the outer wedge, thereby avoiding the defect that the machine part is directly rubbed when the steel wedge is knocked tightly, and achieving the purposes that the machine part is not damaged and the bolt is fastened when the steel wedge is knocked tightly.
The beneficial effects of the utility model are that, the steel wedge is the friction that takes place between the interior outer wedge when striking tight, consequently, the steel wedge can not scotch machine parts when striking tight, and is more practical, simple structure.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a steel wedge with embedded core.
In the figure, 1, outer wedge, 2, step, 3, "U" shaped groove, 4, particle, 5, core wedge, 6, plane, 7, "U" shaped groove.
Detailed Description
In fig. 1, an outer wedge 1 is folded into a shape of < "> by a tough steel plate, the upper inclined plane of the outer wedge is made into a step 2, the upper inclined plane of the outer wedge is ascended in a step manner, a 'U' -shaped groove 3 is formed on a central line below the outer wedge, the length of the 'U' -shaped groove is half of the length of the uppermost step, the width of the 'U' -shaped groove opening is selected according to the diameter of a bolt, and anti-slip particles 4 are arranged on the step plane of the outer wedge; the core wedge 5 is made of a steel block, the upper plane 6 and the lower plane 6 of the core wedge are rough, the plane of the core wedge is provided with a U-shaped groove 7, and the length and the width of the U-shaped groove are the same as those of the U-shaped groove of the outer wedge.
