Abstract
A reverse-side nut detector relates to the technical field of automobile manufacturing and automobile accessories. A connecting plate (2) is arranged at the upper end of a cylinder (1) and provided with a fixed support (3); a protective cover (5) is arranged at one end of the fixed support (3); a proximity sensor (4) is arranged at one end of the protective cover (5) which is internally provided with a spring (6); a stop dog (7) is arranged at the upper end of the spring (6); an oilless lining fixed block assembly (8) is arranged at the upper end of the stop dog (7); and one end of a detection pin (9) is arranged in the oilless lining fixed block assembly (8), and the other end of the detection pin (9) is arranged in a workpiece (10). The reverse-side nut detector can replace imported products, is simple in structure and convenient to operate, effectively shortens the construction period of a project, lowers the production cost and is long in service life.
Description
Technical field
The utility model relates to automobile making and auto parts machinery technical field, relates in particular to a kind of reverse side nut pick-up unit.
Background technology
At present, known reverse side nut detection is to use the nut inductor of import to detect, and the Buying Cycle of the nut inductor of import is long, and cost is than higher, and product quality is stable inadequately, the use that can not be complementary with domestic product, and serviceable life is short.
Summary of the invention
The purpose of the utility model provides reverse side nut pick-up unit, and the product of its ability import substitution is simple in structure, easy to operate, the project duration that shortens effectively, has reduced production cost, long service life.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it by cylinder 1, web joint 2, fixed support 3, closely connect inductor 4, protecting cover 5, spring 6, block 7, no oily lining fixed block assembly 8, test pin 9, workpiece 10 is formed; The upper end of cylinder 1 is provided with web joint 2, and web joint 2 is provided with fixed support 3, and an end of fixed support 3 is provided with protecting cover 5; One end of protecting cover 5 is provided with and closely connects inductor 4; Be provided with spring 6 in the protecting cover 5, the upper end of spring 6 is provided with block 7, and the upper end of block 7 is provided with and has or not oily lining fixed block assembly 8; One end of test pin 9 is arranged in the no oily lining fixed block assembly 8, and the other end of test pin 9 is arranged in the workpiece 10.
The utility model provides power for cylinder 1 by pressurized air, makes cylinder 1 realize stretching out, withdrawing action, through computer PLC or monitor are programmed, monitor or PLC with closely connect inductor 4 and be connected, to reach the purpose of detection.
The utility model is having under the situation of nut; After cylinder 1 stretches out, because test pin 9 diameters are bigger than nut, so can not pass through nut bore; Drive block 7 compression spring 6 that shrinks back; After cylinder 1 stretched out completion, block 7 fell back in the induction range that closely connects inductor 4, and monitor or PLC then have been judged as nut.
The utility model is under the situation of no nut; After cylinder 1 stretches out; Because the diameter of test pin 9 is littler than the bottom outlet of workpiece 10, thus the workpiece bottom outlet can directly be passed, after cylinder 1 stretches out completion; Block 7 is not in the induction range that closely connects inductor 4, and monitor or PLC then are judged as does not have nut.
The product of the utility model ability import substitution, simple in structure, easy to operate, the project duration that shortens effectively, reduced production cost, long service life.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Structural representation when Fig. 2 is the utility model detection nut.
Embodiment:
With reference to Fig. 1, Fig. 2, this embodiment adopts following technical scheme: it by cylinder 1, web joint 2, fixed support 3, closely connect inductor 4, protecting cover 5, spring 6, block 7, no oily lining fixed block assembly 8, test pin 9, workpiece 10 is formed; The upper end of cylinder 1 is provided with web joint 2, and web joint 2 is provided with fixed support 3, and an end of fixed support 3 is provided with protecting cover 5; One end of protecting cover 5 is provided with and closely connects inductor 4; Be provided with spring 6 in the protecting cover 5, the upper end of spring 6 is provided with block 7, and the upper end of block 7 is provided with and has or not oily lining fixed block assembly 8; One end of test pin 9 is arranged in the no oily lining fixed block assembly 8, and the other end of test pin 9 is arranged in the workpiece 10.
This embodiment provides power for cylinder 1 by pressurized air, makes cylinder 1 realize stretching out, withdrawing action, through computer PLC or monitor are programmed, monitor or PLC with closely connect inductor 4 and be connected, to reach the purpose of detection.
This embodiment is having under the situation of nut; After cylinder 1 stretches out, because test pin 9 diameters are bigger than nut, so can not pass through nut bore; Drive block 7 compression spring 6 that shrinks back; After cylinder 1 stretched out completion, block 7 fell back in the induction range that closely connects inductor 4, and monitor or PLC then have been judged as nut.
This embodiment is under the situation of no nut; After cylinder 1 stretches out; Because the diameter of test pin 9 is littler than the bottom outlet of workpiece 10, thus the workpiece bottom outlet can directly be passed, after cylinder 1 stretches out completion; Block 7 is not in the induction range that closely connects inductor 4, and monitor or PLC then are judged as does not have nut.
The product of this embodiment ability import substitution, simple in structure, easy to operate, the project duration that shortens effectively, reduced production cost, long service life.
