Description

Technical Field

[0001] This utility model belongs to the field of tooling technology for ceramic splicing rings, and specifically relates to a high-efficiency ceramic splicing ring processing tooling. Background Technology

[0002] Piezoelectric ceramics, as the basic components of ultrasonic sensors, have a wide range of applications. Due to different application scenarios and technical requirements, the size and shape of the ceramics also vary. In the production of one type of sensor, a ceramic ring sheet needs to be cut into two parts along the central axis, and electrodes are brushed on the cut surface. Then, the two parts of the piezoelectric ceramic are reassembled into a complete ring.

[0003] Therefore, it is necessary to propose a high-efficiency ceramic ring processing fixture that can simultaneously fix multiple ceramic rings. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency ceramic ring splicing tooling. This utility model tooling is simple and easy to operate, and the spliced ​​rings have good concentricity and flatness.

[0005] To solve the above-mentioned technical problems, this utility model provides a high-efficiency ceramic splicing ring processing tooling, including:

[0006] The clamping component includes an arc-shaped clamping plate and a locking element; the two arc-shaped clamping plates are symmetrically distributed and are locked together by the locking element to form a clamping cavity;

[0007] Locking component two is axially inserted into the axial hole of the gasket one and the piezoelectric wafer located in the clamping cavity;

[0008] Gasket 1, with a piezoelectric chip abutting between each two adjacent gaskets 1, and the gasket 1 and the piezoelectric chip are pressed together by the locking member 2.

[0009] Preferably, the two ends of the arc-shaped clamping plate also include integrally formed and connected fixing ear plates, and the two arc-shaped clamping plates are clamped and locked together by the fixing ear plates and the locking member.

[0010] Preferably, the number of locking elements is four.

[0011] Preferably, the first locking component and the second locking component are locking screws and locking nuts.

[0012] Preferably, the first gasket is a polytetrafluoroethylene (PTFE) ring gasket.

[0013] Preferably, the piezoelectric wafer is assembled from two ceramic semi-rings.

[0014] Preferably, the cut surfaces of the two ceramic semi-rings also include a coated epoxy adhesive layer.

[0015] Preferably, it also includes two gaskets, which are sleeved on the locking member two and distributed at the top of the uppermost gasket and the bottom of the lowermost gasket.

[0016] Preferably, the diameter of the clamping cavity of the tooling is adapted to the outer diameter of the piezoelectric wafer.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The tooling designed in this invention allows for convenient assembly of the ceramic rings. The inner diameter of the tooling is equal to the outer diameter of the ring, and the height of the tooling is equal to the thickness of the ceramic ring. Tightening the screws tightly assembles five ceramic rings into one ring, with the outer ring of the ceramic ring pressed against the inner ring of the tooling, ensuring the concentricity of the finished ring. Combined with the pressing action of a flat plate and flat-jaw pliers, the tooling and the ceramic surface are fixed on a single plane. The resulting cured product has good flatness and more closely approximates the original dimensions of the ceramic ring. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] like Figures 1-2 As shown in the figure, this utility model embodiment specifically provides a high-efficiency ceramic splicing ring processing tooling, including:

[0024] The clamping component 1 includes an arc-shaped clamping plate 11 and a locking component 12; the two arc-shaped clamping plates 11 are symmetrically distributed and are locked together by the locking component 12 to form a clamping cavity;

[0025] Locking component 2 is axially inserted into the shaft hole of gasket 3 and piezoelectric wafer 4 located in the clamping cavity;

[0026] Gasket 3, with a piezoelectric chip 4 between each two adjacent gaskets 3, and the gaskets 3 and piezoelectric chips 4 are pressed together by locking member 2.

[0027] Preferably, both ends of the arc-shaped clamping plate 11 also include integrally formed and connected fixing ear plates, which are used to clamp and lock the two arc-shaped clamping plates 11 together.

[0028] Preferably, the number of locking elements 12 is four.

[0029] Preferably, locking component 12 and locking component 2 are locking screws and locking nuts.

[0030] Preferably, gasket 3 is a polytetrafluoroethylene (PTFE) ring gasket.

[0031] Preferably, the piezoelectric chip 4 is assembled from two ceramic semi-rings.

[0032] Preferably, the cut surfaces of the two ceramic semi-rings also include a coated epoxy adhesive layer.

[0033] Preferably, it also includes two gaskets, which are sleeved on the locking member 2 and distributed at the top of the uppermost gasket 3 and the bottom of the lowermost gasket 3.

[0034] Preferably, the diameter of the clamping cavity of the tooling is adapted to the outer diameter of the piezoelectric wafer 4.

[0035] It also includes the following working principles:

[0036] In use, assemble the two clamping parts 1 together with locking parts 12. Locking parts 12 do not need to be tightened. Apply epoxy adhesive to the cut surface of the ceramic sheet and place it into the inner circumference of the fixture (i.e., the clamping cavity) according to the polarity requirements to form a ring. Five ceramic rings can be spliced ​​together, separated by PTFE ring gaskets. Slightly tighten the two locking parts 12 to clamp the ceramic rings and ensure the cut surfaces are aligned. Then, fix the upper and lower end faces of the fixture with locking parts 2, placing PTFE gaskets and metal gaskets on top. Tighten locking parts 22 to press the upper and lower end faces of the ceramic ring together, ensuring the ceramic ring is level and does not misalign. Finally, tighten the two locking parts 12 on the clamping parts 1 to fix the ceramic ring in the radial direction, ensuring no radial misalignment occurs at the joint. The inner diameter of the fixture is equal to the outer diameter of the original ceramic ring, allowing it to tightly enclose the ceramic sheet to form a whole. The height of the fixture is equal to the thickness of the ceramic ring.
