Abstract
The utility model relates to a detection device for workpiece clamping of a machine tool, which is characterized in that: firstly, a workpiece to be processed is loaded and clamped on the machine tool, then air flow circulates in the processing zone between the workpiece and the reference plane of a fixture, and further, the air flow rate is measured through an air pressure detection device and simultaneously the precision of workpiece clamping is detected through a detection module; if the detected precision meets the requirement, the processing is normal; and if the detected precision doesn't meet the requirements, the fixture on the machine tool releases. The detection device comprises a machine tool fixture; and a load-bearing base plate is arranged at the bottom end of the machine tool fixture. The detection device is characterized in that an assistant fixture is arranged on the load-bearing base plate in the position corresponding to the processing area of the workpiece, air pressure detection ports are arranged inside the load-bearing base plate and an air pressure detection module, an air pressure detection device is connected on the output terminal of the air pressure detection module, and the output end of the air pressure detection device is connected with a machine tool control device. Accordingly, the air flow goes through the parts to be detected to detect the workpiece clamping, thereby improving the qualification rate.
Description
Technical field
The utility model relates to a kind of checkout gear and relates in particular to the checkout gear that a kind of workpiece that is used for lathe clamps.
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.
The utility model content
The purpose of this utility model is exactly in order to solve the above-mentioned problems in the prior art, the checkout gear that provides a kind of workpiece that is used for lathe to clamp.
The purpose of this utility model is achieved through the following technical solutions:
Be used for the checkout gear that the workpiece of lathe clamps, 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 described pressure test device connects machine control unit.
The advantage of technical solutions of the utility model 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 purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solutions of the utility model, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the claimed scope of the utility model.In the middle of these accompanying drawings,
Fig. 1 is the organigram that is used for the checkout gear that the workpiece of lathe clamps.
The implication of each Reference numeral is as follows 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 checkout gear that the workpiece that is used for lathe as shown in Figure 1 clamps includes jig 1, and 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.
Be used for seeing in conjunction with actual making of the present utility model: 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 utility model one preferred implementation, the air pressure 〉=0.6Mpa of circulation airflow that the utility model 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 utility model adopted comprises the top of workpiece, the side of workpiece.Can allow 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 utility model 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 allow lathe stop processing.
And then, can further detect the precision that workpiece clamps,, then carry out normal process if meet the requirements by detection module; If undesirable, then anchor clamps unclamp on the lathe, withdraw from workpiece, the adjustment that allows the staff be correlated with.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, after adopting the utility model, 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, guarantee the many places detection, can effectively control the tolerance≤0.03mm of arbitrfary point, workpiece processing back, improve qualification rate.
