Abstract
An electric fixture capable of automatically limiting the depth of screws consists of a first clamping base above and a second clamping base below. The two or one of the clamping bases is driven by power, and the two clamping bases can move relatively to clamp workpieces. Meanwhile, the electric fixture capable of automatically limiting the depth of the screws is linked with an electric screw driver. The electric fixture is characterized in that a conducting layer is arranged on the second clamping base and forms a current loop together with the tool bit of the electric screw driver and a screw screwed in through wires; and the current loop is electrically connected with a control mechanism of the electric screw driver. Combined with the electric screw driver for use, the electric fixture can automatically accomplish the work of limiting the depth of the screwing part of the screw, and can ensure that the screwed screw reaches the specified depth while automatically screwing the screw in.
Description
Technical field
The present invention relates to a kind of anchor clamps of machining, be specifically related to a kind of electric fixture that can the volitional check screw degree of depth.
Background technology
At the modern mechanical manufacture field, more and more stricter to the requirement of the various parameters of workpiece, for example, for holding screw, requiring has strict torque value.So the modern mechanical manufacture field generally adopts electric screw driver (being also referred to as electric screwdriver), described electric screw driver is a kind of electric tool that screw is used that is used to tighten and unscrew; The mechanism of adjusting and torque limiting numerical value generally is housed, and when the screw moment of torsion reached the numerical value of regulation, the sensor of adjusting and torque limiting mechanism sent signal, and electric screw driver stops operating automatically, the moment of torsion that the screw of tightening with assurance has regulation.
But, when some mechanical parts adopts screw fastening, be not that the moment of torsion to screw claims, but the strict regulations screw screws in the degree of depth of parts.This class work at present can only rely on operator's experience to judge, not only is difficult to ensure the uniformity of screw screw-in depth, the quantizating index when also lacking check.This qualification screw screws in the work of the parts degree of depth, and prior art does not still have machinery or instrument automatically to finish.
Summary of the invention
The purpose of this utility model provides a kind of electric fixture of the volitional check screw degree of depth, the electric fixture of this volitional check screw degree of depth and electric screw driver (electric screwdriver) are united use, can automatically finish the work that screw screws in the parts degree of depth that limits, when screwing in screw automatically, can guarantee that the screw that is screwed in reaches prescribed depth.
The scheme of finishing the foregoing invention task is, a kind of electric fixture of the volitional check screw degree of depth, this electric fixture is made up of first holder of top and second holder of below, these two holders (or one of them) by power drive, can relatively move, with clamping work pieces, simultaneously, the electric fixture of this volitional check screw degree of depth and electric screw driver connect, it is characterized in that, be provided with conductive layer above described second holder, this conductive layer above second holder is through the cutter head of lead and electric screw driver, the screw that is screwed in constitutes a current loop, and this current loop is electrically connected with the controlling organization of electric screw driver.
Electric fixture provided by the utility model, see through this power source and drive the operation that this second holder is finished the clamping article with this first holder or loosened article, cooperate the action of electric screw driver simultaneously, during conductive layer above the screw-tipped that is screwed in touches second holder, the electricity loop is connected, the controlling organization of electric screw driver receives the signal of telecommunication, promptly quits work, and reaches the purpose that the control screw reaches prescribed depth.
In the prioritization scheme, be provided with inversion controller in the controlling organization of electric screw driver, during conductive layer above the screw-tipped that is screwed in touches second holder, the electricity loop is connected, the controlling organization of electric screw driver receives the signal of telecommunication, promptly stop precession, and begin the half cycle that reverses, and then quit work.Described inversion controller can be frame for movement (for example, the counter-rotating relay), also can realize by programming or software.
The electric fixture of the volitional check screw degree of depth of the present utility model is united use with electric screw driver, can automatically finish the work that screw screws in the parts degree of depth that limits, and when screwing in screw automatically, can guarantee that the screw that is screwed in reaches prescribed depth.
