Description

The measurement and the dust aspiration device that are used for toolroom machine
Technical field
A kind of measurement and dust aspiration device that is used for toolroom machine, especially rig of the present invention is used to measure working depth and is used for the dust sucking-off.
Background technology
In DE 103 46 207 A1, described a kind of rig, this rig is provided with dust collection container in order to be received in the drilling dust that produces in the workpiece processing, and this dust collection container can be connected with the housing of rig.For this purpose, this dust collection container is provided with a container and takes over, and this container is taken over and can be overlapped on the vent connection that matches that installs on the housing.When the electric drive motor operation of rig, produce a suction streams through draught fan impeller, this suction streams imports to formed dust in the dust collection container via the dust guidance system.
Summary of the invention
Task of the present invention is, creates a kind of measurement and dust aspiration device with simple structural measure, can add the measurement that realizes effective dust sucking-off man-hour and realize working depth simultaneously at workpiece through it.
This task solves according to the invention through the features of claim 1.Dependent claims has provided suitable expanded configuration.
Measurement and dust aspiration device are embodied as the construction unit that constitutes dividually with toolroom machine, but this construction unit can be connected with toolroom machine.Measure with the dust aspiration device and obtain dual-use function, promptly measure the working depth by the tool processes workpiece of toolroom machine the time on the one hand, add the dust of formation in man-hour or the dust sucking-off of smear metal at workpiece on the other hand.Owing to, measure and under the situation of the afunction that does not have toolroom machine, to separate and to be connected again with toolroom machine with the dust aspiration device as the embodiment of independent structures unit.
Measurement and dust aspiration device have a support housing, and an other housing parts keeps with respect to this support housing adjustably, and wherein, support housing is connected with the housing of toolroom machine regularly in rigging position.In support housing and adjustable housing parts, exist one to be used for the dust guidance channel systems that dust is derived.In addition, one be used for measuring working depth measuring system be received in support housing or adjustable housing parts or, wherein, can measure the current degree of depth that reaches through measuring system, the instrument of toolroom machine extend in the workpiece to be processed with this degree of depth.
The adjustment campaign of adjustable housing parts is relevant with working depth, makes only must obtain the adjustment campaign of the housing parts that relates to through the measuring system of measurement and dust aspiration device, so that can therefrom infer working depth.Advantageously, measure and the dust aspiration device constitutes in this wise, make between the adjustment campaign of adjustable housing parts and working depth, to have linear correlation.But also can be nonlinear correlation in principle, as long as between the diverse location of adjustable housing parts and working depth, obtain the corresponding relation of univocality.
Advantageously, in measurement and dust aspiration device, stipulate that a passage of dust guidance channel systems passes adjustable housing parts.This allows dust is formed on the position at it, promptly on the working position between instrument and the workpiece, goes out by the air conductance that passes adjustable housing parts.Passage in the adjustable housing parts advantageously with fixing housing parts, be the other channel connection in the support housing, wherein, this passage can be connected in the zone of its port on the air guidance system in the toolroom machine.For this purpose, the port of passage preferably extends in the fringe region of fixing housing parts.
Can the power of the CD-ROM drive motor of toolroom machine, especially electric drive motor be brought through this mode and to be used to produce air stream; Preferably through the draught fan impeller in the driven tool machine; Wherein, circulation of air is crossed joint and is communicated with dust guidance channel systems in measurement and the dust aspiration device.Not only can produce one in order in the dust guidance channel systems, producing the suction air flow of negative pressure, and can produce one be used for producing overvoltage in the dust guidance channel systems blowing gas stream.Embodiment regulation according to favourable produces a suction air flow, and this suction air flow is suitable for the dust that forms from the machining area sucking-off.And under the blowing gas stream situation with overvoltage in the dust guidance channel systems, air stream points to machining area, and this air stream blows away the dust that forms.
Especially with can be combined by the suction air flow that toolroom machine produces the time, in measurement and dust aspiration device, a dust collection container is set, this dust collection container is arranged in the dust guidance channel systems and catches and deposit the dust particle that is sucked into wherein.Dust collection container not only can be arranged in adjustable housing parts but also can be arranged in fixing housing parts.According to a kind of favourable embodiment regulation; Dust collection container is arranged to free end and the adjacent thus instrument and the workpiece Working position back to fixing support housing of contiguous adjustable housing parts; This has advantage, and promptly the grinding dust only must transport the distance through a weak point till arriving dust collection container when sucking-off.
The design suitable according to another kind, movably housing parts can be bearing on the fixing housing parts with moving axially.The adjustment motion is an axial translational motion thus, can instead release working depth through this translational motion.But adjustable housing parts also is possible with respect to the rotation or the oscillating motion of fixing housing parts in principle.
Adjustable housing parts advantageously is loaded in the position of its elongation by power.For this reason, in measurement and dust aspiration device, be provided with a spring element, this spring element is loaded into adjustable housing parts in the position of squinting out.Add man-hour at workpiece, the power that overcomes spring element along with this adjustable housing parts of increase of working depth is adjusted on the direction of fixing housing parts, and this can pass through the measuring system record.Advantageously, be provided with the display unit of the adjustment campaign that is used to show adjustable housing parts, wherein, the preferred working depth that shows in display unit.Display unit is positioned on the fixing housing parts aptly.
Consider that in principle various dissimilar measuring systems measure the relative motion between fixing and the adjustable housing parts.According to a kind of favourable embodiment, measuring system magnetically constitutes and has measured value transmitter and sensor that matches of a magnetic.This measured value transmitter is advantageously located on the adjustable housing parts, and sensor is positioned on the fixing housing parts.For example use the measuring method of a reluctance type, the linear measure longimetry of the magnetic of this measuring method is because the version in robustness, accuracy, saving space and low energy requirement and because low manufacture costs and be fit to particularly well be applied in portable measurement and the dust aspiration device.The measuring system of this reluctance type comprises a magnetic sensor and a magnet band; Wherein, The magnetic sensor that preferably is arranged on the fixing housing parts is made up of a resistance meausring bridge basically, is formed for the count pulse that depends on distance that signal is prepared electronic installation by this resistance meausring bridge.The magnet band is arranged on the adjustable housing parts on the adjustment direction, makes adjusting generation magnet pulse between moving period, and these magnet pulses are recorded in the sensor.
