Description

TECHNICAL FIELD

[0001] The utility model relates to piezoelectric ceramic processing and manufacturing technical field, especially a simple ceramic ring assembly tool. BACKGROUND

[0002] Piezoelectric ceramics are widely used as basic elements of ultrasonic sensors, and the size and shape of the ceramics are different due to different application scenarios and technical requirements. In production, a sensor needs to cut a ceramic ring into four parts along a cross line, and brush electrodes on the cutting surface, and then reassemble the four piezoelectric ceramics into a complete ring.

[0003] Therefore, a tool is needed to conveniently assemble the ceramic ring and ensure the concentricity and flatness of the assembled ring. SUMMARY

[0004] To solve the above technical problems, the utility model provides a simple ceramic ring assembly tool, which assembles four 1 / 4 ceramic ring pieces into a ring, and the concentricity and flatness of the assembled ring meet the design process requirements. The ring assembly tool is made of polytetrafluoroethylene, and includes an upper half-circle feature body and a lower half-circle feature body. The cross section of the upper half-circle feature body and the lower half-circle feature body is a "J" shape, and both ends are provided with positioning holes. The two feature bodies are assembled by screws.

[0005] In one embodiment of the utility model, before assembling the 1 / 4 ceramic ring pieces, epoxy glue is applied to the cutting surfaces at both ends, and then the pieces are placed in the inner circle of the ring assembly tool according to the polarity requirement. By tightening the screws, the 1 / 4 ceramic ring pieces are clamped and the cutting surfaces are completely matched.

[0006] In one embodiment of the utility model, after the ring assembly tool is clamped and assembled by screws, two polytetrafluoroethylene plates are used to press the upper and lower planes in the height direction.

[0007] In one embodiment of the utility model, the height of the ring assembly tool is equal to the thickness of the 1 / 4 ceramic ring piece.

[0008] The ring assembly tool of the utility model has the following advantages compared with the prior art: the ring assembly tool provides a convenient operation scheme for assembling the ring, and the overall tool is simple and easy to operate, ensuring the concentricity and flatness of the assembled ring. BRIEF DESCRIPTION OF DRAWINGS

[0009] In order to make the content of the utility model more easily understood, the utility model will be further described in detail below according to the specific embodiments of the utility model and in conjunction with the drawings.

[0010] Figure 1 is a schematic diagram of the simple ceramic ring splicing tool.

[0011] As shown, 1, ring splicing tool, 2, 1 / 4 ceramic ring piece, 3, screw. DETAILED DESCRIPTION

[0012] As Figure 1 shown, the embodiment provides a kind of simple ceramic ring splicing tool, the ring splicing tool 1 needs to be spliced into a circular ring with four 1 / 4 ceramic ring piece 2, and the concentricity and flatness of the circular ring spliced well reach the process requirement of design, wherein the ring splicing tool 1 is processed using polytetrafluoroethylene, the ring splicing tool 1 includes upper half circle feature body, lower half circle feature body, and the section of upper half circle feature body, lower half circle feature body is "J" type, and both ends are provided with positioning hole, and two groups of feature bodies are combined and assembled by screw 3 when splicing is used;

[0013] Meanwhile, screw 3 is not tightened, epoxy glue is coated on the section of 1 / 4 ceramic ring piece 2, is placed in tool according to polarity requirement to form a circular ring, and two fixed screws 3 are tightened, so that the circular ring formed by ceramic ring piece is clamped and the section is completely attached.Jamming of the clamped ring splicing tool 1 is pressed by two polytetrafluoroethylene flat plates, then flat-nose pliers can be used to press, to ensure that the surface of the obtained circular ring product is flat.The inner circle radius of ring splicing tool 1 is equal to the outer diameter of the original ceramic circular ring piece, so that the ceramic piece can be tightly wrapped to form a whole, and the height of the tool is equal to the thickness of the ceramic circular ring.

[0014] The ring splicing tool 1 described in the embodiment is relatively convenient to complete the operation of ring splicing, the inner circle radius of ring splicing tool 1 is equal to the outer diameter of the circular ring, the height of the tool is equal to the thickness of the ceramic circular ring, and the four 1 / 4 ceramic ring pieces 2 can be tightly spliced into a circular ring by tightening screw 3, and the outer circle of the ceramic circular ring is tightly attached to the inner circle of the tool, to ensure the concentricity of the finished product circular ring.The pressing of flat plate and flat-nose pliers fixes the tool and ceramic surface on a plane, and the flatness of the cured product is good, and is closer to the outer shape size of the original ceramic circular ring piece.

[0015] Obviously, the above embodiment is only an example for clear illustration, and is not limited to the implementation. For ordinary skilled person in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary or possible to exhaust all implementation. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
