Abstract
The utility model discloses a film tensioning clamp of a piezoelectric film sensor. The film tensioning clamp comprises a base. The center of the base is provided with a through hole, the middle of an inner wall of the through hole of the base is provided with a step, and an inner ring of the base is provided with a plurality of puller bolts. The lower ends of the puller bolts extend out of the base, a lower clamp ring is installed above the step, and the upper ends of the puller bolts abut against the lower surface of the lower clamp ring. An upper clamp ring is arranged above the lower clamp ring, a film is clamped between the upper clamp ring and the lower clamp ring, the base serves as a cylinder made of steel, and the center of the base is provided with the through hole. By means of a structure that the base is matched with the upper clamp ring and the lower clamp ring, the film can be clamped and tensioned only by adjusting the puller bolts, and the film tensioning clamp is simple and convenient to operate, greatly improves the work efficiency and reduces the product rejection rate.
Description
Technical field:
The utility model relates to thin film sensor production equipment field, relates in particular to a kind of piezoelectric film sensor diaphragm stretching anchor clamps.
Background technology:
Piezoelectric transducer is a kind of sensor made from the piezo-electric effect of Cucumber, when the stressed effect of material surface produces distortion, realizes Non-Electricity Measurement thereby its surface has charge generation.
Piezoelectric membrane (PVDF) is a kind of macromolecule sensing material of uniqueness, can be with respect to the variation output voltage signal of pressure or tensile force, it is difficult for broken, has water proofing property, a large amount of continuous drawing, make larger area or longer yardstick, low price, the frequency respective range is wider, therefore be a kind of desirable dynamic strain sheet, can be processed into high efficient and reliable, cheaply vibrating sensor, accelerometer or dynamic switch, also can be used as high audio (〉 1kHz) to the high-fidelity sensor of ultrasonic wave (can up to 100MHz).
Piezoelectric membrane to be processed into sensor, at first need diaphragm stretching, be installed in the shell again and go, do not have tension device dedicated in the past,, not only wasted time and energy one by one with the film stretching tensioning by workman's tool using, the diaphragm uniformity is also bad, defect ware often occurs easily.Therefore imagination provides a kind of equipment to solve this problem.
The utility model content:
The purpose of this utility model just provides a kind of piezoelectric film sensor diaphragm stretching anchor clamps, solution will be processed into sensor with piezoelectric membrane, at first need diaphragm stretching, be installed in the shell again and go, do not have tension device dedicated in the past,, not only wasted time and energy one by one with the film stretching tensioning by workman's tool using, the diaphragm uniformity is also bad, the problem of defect ware often occurs easily.
The technical solution adopted in the utility model is:
A kind of piezoelectric film sensor diaphragm stretching anchor clamps, comprise base, the base center has through hole, base plate through holes inwall middle part is provided with step, and the base inner ring is provided with some puller bolts, and the puller bolt lower end extends outside the base, the step top is equipped with lower snap ring, the puller bolt upper end leans at lower snap ring lower surface, and lower snap ring top is provided with snap ring, and diaphragm is installed between the upper and lower snap ring.
Described base is steel cylinder, and its center has through hole.
Compared with prior art, the beneficial effects of the utility model are:
The utility model cooperates the structure of upper and lower snap ring by base, and puller bolt just can effectively be clamped diaphragm and tensioning as long as regulate, and is easy and simple to handle, greatly improved operating efficiency, reduced the defective products rate.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation top view;
Accompanying drawing 2 is the utility model structural representation cutaway view.
The specific embodiment:
Below in conjunction with accompanying drawing, by embodiment the utility model is described in further detail:
A kind of piezoelectric film sensor diaphragm stretching anchor clamps, comprise base 1, base 1 center has through hole 2, and base plate through holes 2 inwalls middle part is provided with step 3, base 1 inner ring is provided with some puller bolts 4, outside the puller bolt 4 lower end protuberate basic units 1, step 3 tops are equipped with lower snap ring 5, and puller bolt 4 upper ends lean at lower snap ring 5 lower surfaces, lower snap ring 5 tops are provided with snap ring 6, diaphragm is installed between the upper and lower snap ring, and base 1 is steel cylinder, and its center has through hole 2.
Above-described embodiment only is better embodiment of the present utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any apparent improvement and modification all should fall within the protection domain of the present utility model.
