Abstract
The invention discloses a drilling tool for detecting residual stress through a blind hole method. The drilling tool comprises a support, a drill rod and a drill bit, the drill bit is arranged on the lower portion of the drill rod, the drill rod is arranged in the support, the periphery of the drill rod is sleeved with a sleeve, the sleeve and the support are in clearance fit, transverse adjusting nuts connected with the sleeve are arranged on the two sides of the support, supporting legs are arranged on the lower portion of the support, height adjusting nuts are arranged at the connecting positions of the supporting legs and the support, and an universal joint is arranged at the top of the drill rod. The drilling tool is simple in structure, convenient to carry and capable of being easily fixed to a component, meanwhile, alignment is convenient, the depth of a drilled hole is easy to control, the drilling tool can adapt to working on various curved surfaces, the drilling tool can meet the requirements well, the drilled hole is kept to be perpendicular to the surface of a workpiece through positions adjustable in the direction X and the direction Y, an upper position and a lower position, and the universal joint and a speed-adjustable electric hand drill are connected for hole drilling.
Description
Technical field
The present invention relates to a kind of drilling tool, particularly a kind of Blind Hole Method surveys residual stress boring drilling tool.
Background technology
The more residual stress measuring method applied on weldment and foundry goods is at present Blind Hole Method, Blind Hole Method bores a small through hole or blind hole exactly on workpiece, the stress of measured point is discharged, and recorded the dependent variable of release by the strain gauge being attached to Kong Zhouwei in advance, then calculate residual stress according to principle of elasticity.The diameter of boring and the degree of depth are all little, can not affect the normal use of tested component.And this method has higher precision, therefore it has become Application comparison method widely.
Therefore using specific rig to just needing when workpiece is holed, it is simple that this equipment should possess structure, and the feature such as be easy to carry, and facilitates the requirement of Drilling operation.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of Blind Hole Method that can solve the problem and surveying residual stress boring drilling tool.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of Blind Hole Method surveys residual stress boring drilling tool, it is characterized in that: comprise support, drilling rod and drill bit, described drill bit is installed on below drilling rod, described drilling rod is located in support, and the sheathed a set of cylinder in the periphery of drilling rod, described sleeve coordinates with standoff gap, the both sides of support are provided with the lateral adjustments nut with sleeve connection, the below of described support is provided with leg, the junction of described leg and support is provided with height adjusting nut, and the top of described drilling rod is provided with a universal joint.
As a further improvement on the present invention, a magnifying glass is also installed in the top of described drilling rod.
As a further improvement on the present invention, the bottom of described leg is provided with adhesive pad.
The invention has the beneficial effects as follows: borehole drilling lamps structure of the present invention is simple, be easy to carry, be easy to be fixed on component, centering is convenient simultaneously, and drilling depth is easy to control, and can adapt in various bent general work, this drilling tool can realize above-mentioned requirements preferably, by position and the upper and lower position of 4 adjustable X, Y-direction, to keep boring perpendicular to surface of the work, be connected to implement with adjustable speed electric hand drill with universal joint and hole.
