Description
Technical field
The utility model relates to a kind of turning attachment surface iron filings checkout gear.
Background technology
Lathe use fixture clamp workpiece.After using lathe to process workpiece, fixture locating surface has more iron filings and remains.Therefore, when use lathe is processed another workpiece, after being compressed by trade union college pressing plate, the end face that can there is this workpiece touches the situation of mao gouge.
At present, domestic lathe does not have iron filings automatic detection function after trade union college, generally before trade union college, can only manually clear up chucking surface iron filings by operator.Existing surface of the work is as easy as rolling off a log touches a mao gouge, and its fraction defective is up to 10% ~ 20%.
Utility model content
The technical problems to be solved in the utility model is the defect that the surface of the work existed to overcome prior art easily touches mao gouge, provides a kind of turning attachment surface iron filings checkout gear.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of turning attachment surface iron filings checkout gear, it comprises a lathe, described lathe is provided with one for the fixture of holding workpiece, its feature is, described fixture is a lathe chuck, described lathe chuck comprises the locating surface of one and absorption surface, described locating surface is provided with one first pore and one second pore, the diameter of described first pore and the diameter of described second pore are 1mm, described lathe is provided with first gas passage be communicated with described first pore, one the second gas passage be communicated with described second pore, one the 3rd gas passage, described first gas passage and described second gas passage are all communicated in described 3rd gas passage, the pressure sensor of a detection gas pressure is provided with in described 3rd gas passage, described 3rd gas passage is communicated with a gas generator part.
Preferably, described lathe chuck also comprises a pressing plate, and described pressing plate is positioned at the top of described locating surface.By pressing plate, realize the stable holding to workpiece.
Preferably, described gas generator part is air pump.Air pump can provide stable source of the gas.
Preferably, described lathe is also provided with a voice guard, described voice guard is electrically connected with described pressure sensor.Voice guard can sound the alarm.
Positive progressive effect of the present utility model is: adopt device of the present utility model, can detect residual scrap iron before work pieces process, and thoroughly can prevent touching mao gouge and occur, it has safe and reliable, simple and practical, cheap advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is that A in Fig. 1 is to schematic diagram.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As depicted in figs. 1 and 2, a kind of turning attachment surface iron filings checkout gear, it comprises lathe 1, lathe 1 is provided with the fixture for holding workpiece 2, this fixture is lathe chuck 3, lathe chuck 3 comprises the locating surface 31 contacted with workpiece 2, locating surface 31 is provided with the first pore 4 and the second pore 5, the diameter of the first pore 4 and the diameter of the second pore 5 are 1mm, lathe 1 is provided with the first gas passage 41 be communicated with the first pore 4, the second gas passage 51 be communicated with the second pore 5, also be provided with the 3rd gas passage 6, first gas passage 41 and the second gas passage 51 are all communicated in the 3rd gas passage 6, the pressure sensor 7 detecting gas pressure is provided with in 3rd gas passage 6, 3rd gas passage 6 is communicated with air pump 8.Lathe 1 is also provided with voice guard (not shown on figure), voice guard is electrically connected with pressure sensor 7.Lathe chuck 3 also comprises pressing plate 32, and pressing plate 32 is positioned at the top of locating surface 31, and workpiece 2 can be held between pressing plate 32 and locating surface 31.
This device mainly utilizes gas bridge circuit theory.Because the first gas passage, the second gas passage are connected with the 3rd gas passage, therefore, the air pressure in these three gas passages is identical.
When workpiece is not installed, air pump produces gas, have no occluder on the first pore and the second pore, first gas passage and the second gas passage are communicated in air, pressure sensor detects the pressure in the 3rd gas passage, sends alarm signal, forbid lathe process to lathe.
When trade union college is between pressing plate and locating surface, if there are iron filings in locating surface, and the magnitude range of iron filings is 0.1mm-0.4mm usually, therefore, now there is the gap of 0.1mm-0.4mm between workpiece and locating surface, like this, make the air pressure between the first pore on locating surface and the second pore little, now, gas pressure in first gas passage, the second gas passage, the 3rd gas passage is consistent with the air pressure above locating surface, pressure sensor detects the pressure in the 3rd gas passage, sends alarm signal, forbid lathe process to lathe.
When there is no iron filings between workpiece and locating surface, namely when the gap between workpiece and locating surface is less than 0.05mm, because the gap of workpiece and locating surface is less, make the air pressure between the first pore on locating surface and the second pore larger, now, gas pressure in first gas passage, the second gas passage, the 3rd gas passage is consistent with the air pressure above locating surface, pressure sensor detects the pressure in the 3rd gas passage, sending to lathe can normal working signal, and lathe can normal process.
Visible, when the gap between workpiece and locating surface is determined value, the air pressure in gas passage also has corresponding numerical value.This device is according to this principle, and setting pressure sensor gives the alarm when certain air pressure, does not have iron filings to ensure to process between front workpiece and locating surface.
Adopt the device of the present embodiment, can detect residual scrap iron before work pieces process, thoroughly can prevent touching mao gouge and occur, it has safe and reliable, simple and practical, cheap advantage.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
