The utility model provides a straightness inspection device of screw adjusts luminance, include: the device comprises a workbench 1, a fixed positioning device 2 and a mobile inspection mechanism;
the workbench 1 is provided with a fixed positioning device 2 and a mounting seat 5;
the fixed positioning device 2 is provided with a through hole for accommodating a dimming screw;
the mobile inspection mechanism includes: a cylinder 3 and a check block 4; the cylinder body of the cylinder 3 is fixed on the mounting seat 5, and the end part of the piston rod of the cylinder 3 is connected with the inspection block 4;
the inspection block 4 faces the fixed positioning device 2, and a hole for accommodating a dimming screw is formed in one side, facing the fixed positioning device 2, of the inspection block 4; the check block 4 can slide under the drive of the cylinder 3.
Preferably, an infrared position sensor is provided on the side of the cylinder 3 where it protrudes most.
Preferably, the diameter of the through hole of the fixed positioning device 2 is larger than the diameter of the rod part of the dimming screw and smaller than the diameter of the cap part of the dimming screw.

Detailed Description
In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
As shown in fig. 2, the embodiment of the present invention provides a straightness inspection device for a dimming screw, including: a table 1, a fixed positioning device 2 and a mobile inspection mechanism.
The workbench 1 is provided with a fixed positioning device 2 and a mounting seat 5.
The fixed positioning device 2 is provided with a through hole for accommodating a dimming screw A; the diameter of the through hole of the fixed positioning device 2 is larger than the diameter of the rod part of the dimming screw A and smaller than the diameter of the cap part of the dimming screw A. The rod part of the dimming screw can penetrate through the fixed positioning device 2, and the cap part is clamped.
The mobile inspection mechanism includes: a cylinder 3 and a check block 4; the cylinder body of the cylinder 3 is fixed on the mounting seat 5, and the end part of the piston rod of the cylinder 3 is connected with the inspection block 4.
The inspection block 4 faces the fixed positioning device 2, and a hole for accommodating the dimming screw A is formed in one side, facing the fixed positioning device 2, of the inspection block 4; the checking block 4 can slide between the fixed positioning device 2 and the mounting seat 5 under the driving of the cylinder 3. The diameter of the hole of the inspection block 4 is larger than the diameter of the end of the rod part of the dimming screw, so that qualified products with qualified straightness can be inserted, but unqualified products with deviation in straightness cannot be inserted, and the straightness inspection of the dimming screw A can be realized.
An infrared position sensor is arranged on one side of the cylinder 3 extending out of the maximum position, the infrared position sensor is used for detecting the check block 4, and whether the product is bent or not is judged by detecting the position of the check block 4. As shown in fig. 2, if the end of the rod of the dimming screw can be inserted into the inspection block 4, the cylinder 3 moves to the maximum position, the infrared position sensor can detect the inspection block 4, and the signal is transmitted to the upper computer to judge that the product is qualified; as shown in figure 3, if the end of the rod part of the dimming screw cannot be inserted into the inspection block 4, the movement of the air cylinder 3 is blocked, the infrared position sensor cannot detect the inspection block 4, signals cannot be acquired, and the upper computer judges that the product is unqualified.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: it is to be understood that modifications may be made to the technical solutions described in the foregoing embodiments, or some or all of the technical features may be equivalently replaced, without substantially departing from the scope of the technical solutions of the embodiments of the present invention.
