Description

Technical Field

[0001] The utility model relates to the field of ceramic sintering jigs, in particular to a sintering jig for a copper-clad ceramic substrate. Background Art

[0002] The sintering jig for copper-clad ceramic substrates is a professional tool used in the manufacturing process of electronic ceramics. It is mainly used to fix and support the copper-clad ceramic substrate to maintain its shape and position during the high-temperature sintering process. Sintering is to mix ceramic powder with a binder to form a green body, and then solidify it at high temperature to form a hard ceramic body. In this process, due to the extremely high temperature, the substrate may be deformed or damaged if there is no suitable jig.

[0003] The sintering jig of the traditional copper-clad ceramic substrate is not easy to adjust the length during use, which makes it impossible to use it when substrates of other sizes need to be sintered. Other specifications of jigs need to be used, which has low applicability and high cost of use.

[0004] Therefore, those skilled in the art provide a sintering jig for a copper-clad ceramic substrate to solve the problems raised in the above background technology. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art and proposes a sintering jig for a copper-clad ceramic substrate. Side plates are arranged at the front and rear ends of the jig. The two side plates can ensure that the two ends are heated evenly. The side plates can be rotated by support rods so that the support blocks on both sides support them on both sides to achieve fixation. The side plates can be moved and adjusted by loosening them, thereby improving the adjustability of the jig. When the size of the jig needs to be changed, it is convenient to adjust and has higher applicability.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sintering jig for a copper-clad ceramic substrate comprises a jig body, side plates are arranged at both the front and rear ends of the top of the jig body, a pair of extension plates are fixedly arranged on opposite sides of the two side plates, support rods are sleeved in the middle of the two pairs of extension plates, threaded rods are fixedly arranged at both the front and rear ends of the two support rods, support blocks are arranged on the four threaded rods, threaded holes are opened inside the four support blocks, and the four threaded holes are respectively threadedly connected to the four threaded rods.

[0008] Through the above technical solution, the support rod on one side of the side plate can be rotated to drive the threaded rod to rotate, and the threaded rod drives the support blocks on both sides to move to both sides, so as to support the fixture body and fix the side plate, thereby facilitating the adjustment of the position of the side plate to adjust the size of the fixture.

[0009] Furthermore, a top plate is provided on the top of the fixture body, and mounting grooves are provided at four corners of the top of the fixture body. Mounting blocks are fixedly provided at four corners of the bottom ends of the four top plates, and the four mounting blocks are respectively engaged with four mounting grooves.

[0010] Through the above technical solution, the top plate and the fixture body are installed by clamping the mounting block and the mounting groove, which not only improves the coupling between the top plate and the fixture, but also avoids the top cover from shifting.

[0011] Furthermore, the top four corners of the top plate are provided with limiting holes;

[0012] Furthermore, bases are fixedly provided at the four corners of the bottom end of the fixture body;

[0013] Through the above technical solution, the base can be inserted into the limiting hole, making it easy to stack and fire the fixture.

[0014] Furthermore, a hexagonal control column is fixedly arranged in the middle of the support rod;

[0015] Through the above technical solution, the hexagonal control column can be controlled and fixed using a wrench.

[0016] Furthermore, each of the support blocks is provided with anti-slip grooves on the outside;

[0017] Through the above technical solution, the anti-slip pattern can increase the friction force, avoid the deviation of the support block, and make its fixation more stable.

[0018] The utility model has the following beneficial effects:

[0019] 1. The utility model proposes a sintering jig for a copper-clad ceramic substrate. Side plates are arranged at the front and rear ends of the jig. The two side plates can ensure that the two ends are heated evenly.
