Abstract
The invention discloses a device for detecting the coaxiality of a circular hole. The device comprises a measuring head. The measuring head is provided with a first air outlet hole and a second air outlet hole. The first air outlet hole is connected with a pneumatic device through a first air pipe, and the second air outlet hole is connected with the pneumatic device through a second air pipe. The pneumatic device is connected with an air source connecting device. By the adoption of the device, a workpiece can be measured immediately after being machined without wasting time; moreover, data of all parts of the circular hole can be output rather than only one datum, so unqualified parts can be shown more visually, and errors caused by fewer sampling points are eliminated.
Description
Technical field
The present invention relates to a kind of device and method of test hole right alignment.
Background technology
At present, right alignment is a kind of form and position tolerance project common during engineering goods detect.For regular axial workpiece, generally can adopt V type support, steel ball adds the appliance special for detecting such as lever indicator or deflection instrument and combine accessory to detect right alignment; For casing hole type parts, mandrel generally can be adopted to add lever indicator or utilize roundness measuring equipment to detect right alignment.But for the irregular endoporus of some large parts (as machine tool chief axis etc.) or irregular axial workpiece and box parts, adopt conventional method to measure right alignment and be then difficult to realize or bother very much.
Now, the method used in test hole right alignment is three-dimensional coordinates measurement substantially, namely right alignment measured by employing three coordinate measuring machine (CMM), compared with special axiality measuring apparatus, it is need not turning of work piece that CMM measures the maximum feature of right alignment, need not special mandrel or special stand, need not mechanical line-up, only with measuring probe to workpiece Sample point collection, need can export measurement result fast.But when measuring right alignment with CMM, due to the difference understood datum axis, or it is different to element to be measured shaft centerline measurement method, or it is different to right alignment evaluation method, and CMM adopts the reasons such as the impact of point tolerance, occur the phenomenon that measuring result error is comparatively large, repeatability is poor sometimes, namely measurement result truly can not reflect the real coaxiality error of part.
Summary of the invention
The object of the invention is to overcome above deficiency, a kind of device and method of test hole right alignment is provided, can disposablely by the coaxality measurement of all directions of a circular hole out can immediately measure, as long as can learn to use without the need to some simple trainings of professional.
Object of the present invention is achieved through the following technical solutions: a kind of cleaning and dewatering device of automobile engine oil pan die-cast product, comprise and measure side head, measure side head and be provided with the first venthole and the second venthole, first venthole is all connected with a qigong device by the second tracheae by the first tracheae, the second venthole, and qigong device is connected with source of the gas coupling arrangement.
Further improvement of the present invention: the multiplying power regulating valve on pneumatic means and zero-bit regulating valve.
A method for test hole right alignment, concrete steps are as follows:
A, first start the control inerface of pneumatic means, setting source of the gas enters from the second tracheae, determine that rear measurement side head puts into check gauge, regulate the multiplying power regulating valve on pneumatic means and zero-bit regulating valve, the numerical value of multiplying power regulating valve and zero-bit regulating valve is all set as 0; Close the second tracheae as gas, open the first tracheae, gas is entered from the first tracheae, carry out adjustment multiplying power regulating valve and zero-bit regulating valve again, the numerical value of multiplying power regulating valve and zero-bit regulating valve is adjusted to 0, repeat above action like this, until when exchanging tracheae and carrying out air inlet, the numeral on pneumatic means no longer changes.
B, measurement side head to be taken out from calibration block, put into round-meshed workpiece, close the first tracheae, open the second tracheae, rotation measuring side head makes the numeral on pneumatic means be 0, then changes, close the second tracheae, open the first tracheae air inlet, the numerical value on record pneumatic means, this value is the right alignment numerical value in this hole.
The present invention compared with prior art has the following advantages: the present invention immediately can measure after workpiece carries out processing, there is no unnecessary time waste, and can data be had to export each position of circular hole, data can not be confined to, can be more vivid be shown at underproof position.And overcome and adopt a little less error brought.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-measures side head, 2-second venthole, 3-first venthole, 4-first tracheae, 5-second tracheae, 6-qigong device, 7-source of the gas coupling arrangement.
embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 shows a kind of device of test hole right alignment of the present invention and the embodiment of detection method, comprise and measure side 1, measure side 1 and be provided with the first venthole 3 and the second venthole 2, carry out the circle at two positions up and down of a measurement circular hole respectively, the air that this two place connects is the pressurized air carrying out regulating rear output by pneumatic means, first venthole 3 is by the first tracheae 4, second venthole 2 is all connected with a qigong device 6 by the second tracheae 5, qigong device 6 is connected with source of the gas coupling arrangement 7, multiplying power regulating valve on pneumatic means 6 and zero-bit regulating valve.
A method for test hole right alignment, concrete steps are as follows:
The control inerface of A, first startup pneumatic means 6, setting source of the gas enters from the second tracheae 5, determine that check gauge is put in rear measurement side 1, regulate the multiplying power regulating valve on pneumatic means 6 and zero-bit regulating valve, the numerical value of multiplying power regulating valve and zero-bit regulating valve is all set as 0; Close the second tracheae 5 as gas, open the first tracheae 4, gas is entered from the first tracheae 4, carry out adjustment multiplying power regulating valve and zero-bit regulating valve again, the numerical value of multiplying power regulating valve and zero-bit regulating valve is adjusted to 0, repeat above action like this, until when exchanging tracheae and carrying out air inlet, the numeral on pneumatic means no longer changes;
B, measurement side 1 to be taken out from calibration block, put into round-meshed workpiece, close the first tracheae 4, open the second tracheae 5, rotation measuring side 1 makes the numeral on pneumatic means 6 be 0, then changes, close the second tracheae 5, open the first tracheae 4 air inlet, the numerical value on record pneumatic means 6, this value is the right alignment numerical value in this hole.
The present invention can disposablely by the coaxality measurement of all directions of a circular hole out can measure immediately, as long as can learn to use without the need to some simple trainings of professional.The present invention immediately can measure after workpiece carries out processing, there is no unnecessary time waste, and can data be had to export each position of circular hole, data can not be confined to, can be more vivid underproof position be shown, and overcome and adopt a little less error brought.
