Description
Technical Field
The utility model belongs to the technical field of workpiece machining and specifically relates to a workpiece surface unevenness detection device based on gas tightness is placed in planarization detection device field.
Background
When a workpiece is machined, the workpiece is usually required to be placed on a workbench for machining, the plane where the workbench is located is usually used as a reference plane for workpiece machining, and due to the fact that the workpiece is a blank, unevenness may exist on the surfaces of different blanks or foreign matters exist on the surface of the workbench, the workpiece is not parallel to the plane of the workbench. If the workpiece is not parallel to the workbench, the machining reference deviates, so that the workpiece cannot be machined according to the preset dimensional precision, and the workpiece needs to be scrapped.
Disclosure of Invention
To the situation of the prior art, the utility model aims to provide a can judge whether the work piece places the smooth workpiece surface irregularity detection device based on the gas tightness when work is placed. In order to realize the technical purpose, the utility model adopts the technical scheme that:
Workpiece surface irregularity detection device based on gas tightness for the flatness that the work piece was placed or the flatness of work piece surface detects, and it includes:
The upper end surface of the workbench is used for placing a workpiece, a plurality of channels are arranged in the workbench, and one ends of the channels extend to the upper end surface area of the workbench, which is used for being attached to the workpiece;
One end of the gas pipeline is connected with the other ends of the channels of the workbench through connecting pieces;
The gas source is used for providing high-pressure gas and is fixedly connected with the other end of the gas pipeline;
And the pressure sensor is connected in the gas pipeline and used for detecting the pressure in the gas pipeline.
As a possible implementation manner, further, a branch extends from the side of the gas pipeline, and the pressure sensor is connected to the branch.
As a possible implementation manner, further, the pressure sensor is a digital display pressure sensor or an analog pressure sensor.
As a possible implementation, further, the air source is an air pump.
Adopt foretell technical scheme, compared with the prior art, the utility model, its beneficial effect who has is: this scheme ingenious utilization air supply output gas, then let in it in the passageway of workstation, and the work piece of arranging on the workstation in can be owing to push down the passageway, consequently can produce certain atmospheric pressure, carry out pressure detection by pressure sensor to conveying gas's gas pipeline again, when laminating existence unevenness between work piece and the workstation, then pressure sensor's pressure value can be less than the gas pressure of air supply output, when the air supply exports gas with 1 Mpa pressure promptly, if the work piece has the unevenness, then can have the condition of decompression, pressure sensor's detection pressure can be less than 1 Mpa more promptly, consequently, can simply judge whether the work piece is levelly and smoothly placed, so that operating personnel can know as early as possible whether the work piece is placed in place.
Drawings
The scheme of the invention is further explained by combining the attached drawings and the detailed embodiment:
FIG. 1 is a schematic diagram of one of the schematic embodiments of the present invention;
FIG. 2 is a schematic diagram of a second embodiment of the present invention;
Fig. 3 is a schematic diagram of a third embodiment of the present invention.
Detailed Description
As shown in fig. 1 to 3, the utility model discloses workpiece surface unevenness detection device based on gas tightness for the planarization that the work piece was placed or workpiece surface's planarization detects, and it includes:
The device comprises a workbench 1, a plurality of channels 11 and a plurality of clamping pieces, wherein the upper end surface of the workbench 1 is used for placing a workpiece 5, one end of each channel 11 extends to the upper end surface area of the workbench 1, which is used for being attached to the workpiece 5;
One end of the gas pipeline 2 is connected with the other ends of the channels 11 of the workbench 1 through connecting pieces 21 (such as connecting sleeves);
The gas source 3 is used for providing high-pressure gas and is fixedly connected with the other end of the gas pipeline 2;
A pressure sensor 4 connected in the gas pipe 2 and detecting the pressure inside the gas pipe 2.
As a possible embodiment, further, a branch 22 extends from the side of the gas pipeline 2, and the pressure sensor 4 is connected to the branch 22; and as a possible option, the pressure sensor 4 may be a digital display pressure sensor or an analog pressure sensor.
In addition, as a possible implementation manner, further, the gas source 3 may be an air pump, and the output of the gas with a constant pressure is performed by the air pump.
This scheme ingenious utilization air supply 3 output gas, then let in it in the passageway 11 of workstation 1, and the work piece of arranging on workstation 1 can be owing to withstand pressure passageway 11, consequently can produce certain atmospheric pressure, carry out pressure detection by pressure sensor 4 to gas transmission's gas pipeline 2 again, when the laminating has the unevenness between work piece 5 and the workstation 1, then pressure sensor 4's pressure value can be less than the gas pressure of air supply output, when air supply 3 carries out output gas with 1 Mpa pressure, if work piece 5 has the unevenness, then the condition that can have the decompression, the detection pressure of pressure sensor 4 can be less than 1 Mpa more promptly, consequently, can simply judge whether work piece 5 is levelly and smoothly placed, whether make operating personnel can know work piece 5 and place as early as possible.
Referring to fig. 1, when the workpiece 5 is tightly attached to the worktable 1, the pressure of the gas pipeline 2 detected by the pressure sensor 4 is approximately consistent with the pressure at the output end of the gas source 3.
Referring again to fig. 2, when there is a gap 6 between the workpiece 5 and the table 1, i.e. some impurities or other elevated components are still present, the pressure in the gas pipe 2 detected by the pressure sensor 4 will be less than, or even substantially less than, the pressure at the output of the gas source 3.
Referring to fig. 3, when there are gaps 6 on the joint surface between the workpiece 5 and the worktable 1, that is, there are some rugged regions on the joint end surface of the workpiece 5, the pressure of the gas pipeline 2 detected by the pressure sensor 4 will be smaller than, even much smaller than, the pressure at the output end of the gas source 3.
The above is the embodiment of the present invention, and to the ordinary skilled in the art, according to the teaching of the present invention, the equal changes, modifications, replacements and variations of the claims should all belong to the scope of the present invention without departing from the principle and spirit of the present invention.
