The method is characterized by comprising the following steps of: clamping a workpiece to be processed on the machine tool; circulating air flow in a processing area between the workpiece and a reference surface of a clamp; detecting air flow values by using an air pressure detection device, simultaneously detecting the accuracy of workpiece clamping by a detection module, if the accuracy meets the requirement, normally processing; and if the accuracy does not meet the requirement, loosening the clamp on the machine tool. The workpiece clamping detection device comprises the machine tool clamp; the bottom of the machine tool clamp is provided with a bearing base plate; auxiliary clamps are arranged at the position, corresponding to the processing part of the workpiece, of the bearing base plate; air pressure detection ports are formed in the bearing base plate and the air pressure detection module; and an output end of the air pressure detection module is connected with the air pressure detection device. An output end of the air pressure detection device is connected with a machine tool control device. Therefore, air flow circulates all parts to be detected so as to detect workpiece clamping; and yield is improved.
Description
Technical field
The present invention relates to its device of a kind of detection method relates in particular to a kind of workpiece that is used for lathe and clamps detection method and device thereof.
Background technology
With regard to present machine tooling field, the means that its detection clamps often adopt non-contact laser to detect.But, adopt this method and relevant equipment all can't detect the situation of workpiece and the whole datum level of anchor clamps.And, because the environment of machine tooling is more abominable, be full of a large amount of cooling cutting fluids and various iron filings disability, can influence the light path conduction of laser like this, measure inaccuracy.Simultaneously, workpiece and the space between the anchor clamps to be processed are especially little, can't guarantee that the detection of laser puts in place.
Moreover the existing machine tool method detects workpiece automatically and clamps situation, and workmanship can only reach 20% qualification rate, and the loss that causes because of quality can't be born at all by enterprise.
Summary of the invention
The object of the invention is exactly the problems referred to above that exist in the prior art in order to solve, and provides a kind of workpiece that is used for lathe to clamp detection method and device thereof.
The object of the invention is realized through following technical scheme:
The workpiece that is used for lathe clamps detection method, and it may further comprise the steps:
1. step installs to workpiece clamp to be processed on the lathe;
Step 2., circulation has an air-flow in the machining area between workpiece and fixture datum;
3. step adopts pressure test device to detect air-flow numerical value, if the air pressure of air-flow descends, then lathe stops processing; If the air pressure of air-flow is constant, then lathe continues next step;
4. step detects the precision that workpiece clamps through detection module, if meet the requirements, then carries out normal process; If undesirable, then anchor clamps unclamp on the lathe, withdraw from workpiece.
The above-mentioned workpiece that is used for lathe clamps detection method, and wherein: step is the air pressure >=0.6Mpa of said circulation airflow 2..
Further, the above-mentioned workpiece that is used for lathe clamps detection method, and wherein: the step 2. machining area of said workpiece comprises the top of workpiece, the side of workpiece.
Further, the above-mentioned workpiece that is used for lathe clamps detection method, and wherein: step 3. air-flow air pressure descends, and then representes to have on the lathe cutting residue or the distortion of workpiece benchmark.
The workpiece that is used for lathe clamps checkout gear; Include jig; Described jig bottom is provided with bearing substrate, and wherein: processing place of corresponding workpiece is provided with auxiliary clamp on the described bearing substrate, is provided with the air pressure detection port in described bearing substrate and the air pressure detection module; Be connected with pressure test device on the output of described air pressure detection module; The output of said pressure test device connects machine control unit.
The advantage of technical scheme of the present invention is mainly reflected in: the situation that can't detect workpiece and the whole datum level of anchor clamps when having removed non-contacting laser detection from; The circulation of air-flow can spread all over everywhere; Guarantee the many places detection; Can effectively control the tolerance≤0.03mm of arbitrfary point, workpiece processing back, improve qualification rate.
Description of drawings
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical scheme of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of requirement protection of the present invention.In the middle of these accompanying drawings,
Fig. 1 is the organigram that the workpiece that is used for lathe clamps checkout gear.
The implication of each Reference numeral is following among the figure:
1 jig, 2 bearing substrates
3 auxiliary clamps, 4 air pressure detection port
5 pressure test devices, 6 machine control units
7 workpiece
The specific embodiment
The workpiece that is used for lathe clamps detection method, and its special feature is may further comprise the steps: at first, workpiece clamp to be processed is installed on the lathe, carry out the preparation of processing and detection.
Then, circulation has air-flow in the machining area between workpiece and fixture datum.In conjunction with the present invention's one preferred implementation, the air pressure >=0.6Mpa of circulation airflow that the present invention adopts.Like this, can guarantee the follow-up preferable feedback that has, be convenient to the detection of pressure test device.And, consider that air-flow can have comparatively perfect free air space, so that workpiece is carried out perfect detection, the machining area that the present invention adopted comprises the top of workpiece, the side of workpiece.Can let air-flow can flow through around the workpiece like this.
Then, adopt pressure test device to detect air-flow numerical value, if the air pressure of air-flow descends, then lathe stops processing; If the air pressure of air-flow is constant, then lathe continues next step.Specifically, from detection method that the present invention adopts,, then represent to have on the lathe cutting residue or the distortion of workpiece benchmark if air-flow air pressure descends.Therefore, these defectives can cause workpiece processing back bigger error to occur, need let lathe stop processing.
And then, can come further to detect the precision that workpiece clamps,, then carry out normal process if meet the requirements through detection module; If undesirable, then anchor clamps unclamp on the lathe, withdraw from workpiece, the adjustment that lets the staff be correlated with.
Again further; Consider that the detection method that the present invention adopts can better obtain implementing; As shown in Figure 1, provide a kind of workpiece that is used for lathe to clamp checkout gear at present, include jig 1; Described jig 1 bottom is provided with bearing substrate 2, and its unusual part is: corresponding workpiece 7 processing place are provided with auxiliary clamp 3 on the described bearing substrate 2.Simultaneously, in bearing substrate 2 and air pressure detection module, be provided with air pressure detection port 4.And, be connected with pressure test device 5 on the output of air pressure detection module; The output of this pressure test device 5 connects machine control unit 6.
Through above-mentioned character express and combine accompanying drawing to find out; After adopting the present invention; Can't detect the situation of workpiece and the whole datum level of anchor clamps when having removed non-contacting laser detection from, the circulation of air-flow can spread all over everywhere, guarantees that many places detect; Can effectively control the tolerance≤0.03mm of arbitrfary point, workpiece processing back, improve qualification rate.
