[0025] In this embodiment, the whole device is placed in a vacuum heating furnace. Two ceramic workpieces that have been connected by welding material are placed on the base 1. The adjusting mechanism 3 drives the two clamping blocks 2 (the clamping blocks 2 can be replaced according to the shape of the ceramic workpiece) to move relatively, so as to fix the two sides below the ceramic workpiece. At the same time, the top of the ceramic workpiece is fixed by operating the fixing mechanism. Then, according to the height of the ceramic workpiece, the use height of the positioning blocks 6 (the positioning blocks 6 can be replaced according to the shape of the ceramic workpiece) is adjusted by the lifting mechanism. Then, the horizontal position of the positioning blocks 6 is adjusted by the moving mechanism, so that the positioning blocks 6 clamp and fix the connection position of the outer wall of the ceramic workpiece. At this time, the two positioning blocks 6 on the placement frame 5 are located above and below the connection of the two ceramic workpieces. Through the overall operation, the upper, lower and middle positions of the ceramic workpiece can be stably fixed, improving the stability during the brazing process of the ceramic workpiece.

[0026] In a further preferred embodiment of the present invention, the adjusting mechanism 3 includes: a bidirectional screw 301 rotatably installed on the base 1 through a damping rotating shaft; two mounting blocks 302 threadedly sleeved on the bidirectional screw 301, and the two mounting blocks 302 are respectively fixedly connected to the two clamping blocks 2.

A limiting rod is fixedly installed on the base 1, and the limiting rod is slidably connected to the two mounting blocks 302. The limiting rod limits the mounting blocks 302, so that the bidirectional screw 301 drives the two mounting blocks 302 to move relatively, thereby driving the two clamping blocks 2 to move relatively to fix the two sides below the ceramic workpiece.

[0028] In a further preferred embodiment of the present utility model, the fixing mechanism includes: a first lead screw 7 threadedly installed on the mounting bracket 101; a positioning bracket 8 fixedly installed at the bottom of the first lead screw 7, and the positioning bracket 8 is used to fix the top of the ceramic workpiece.

The mounting shell 803 is fixedly installed on the connecting plate 801. The spring 804 is fixedly installed inside the mounting shell 803. The guide bracket 805 is slidably installed inside the mounting shell 803, and the guide bracket 805 is fixedly connected to the positioning plate 802.

[0031] In this embodiment, when the positioning bracket 8 fixes the top of the ceramic workpiece, under the interaction of the spring 804 and the guide bracket 805, the positioning plate 802 can have a certain buffering property, so as to avoid excessive extrusion of the ceramic workpiece and play a certain protective role for the ceramic workpiece.

[0032] In a further preferred embodiment of the present utility model, the moving mechanism includes: a second lead screw 9 rotatably installed on the mounting bracket 101 through a damping rotating shaft; a mounting plate 10 threadedly sleeved on the second lead screw 9, and the mounting plate 10 is fixedly connected to the connecting frame 4.

[0033] In this embodiment, when it is necessary to clamp and fix the outer wall of the ceramic workpiece with the positioning block 6, rotate the second lead screw 9. The mounting bracket 101 is fixedly installed with a limiting rod, and the limiting rod is slidably connected to the mounting plate 10. The limiting rod limits the mounting plate 10, so that the second lead screw 9 drives the mounting plate 10 to move, and then drives the positioning block 6 to move to clamp and fix the outer wall of the ceramic workpiece, and improve the stability during the brazing process of the ceramic workpiece.

[0034] In a further preferred embodiment of the present utility model, the lifting mechanism includes: a third lead screw 11 fixedly installed on the connecting frame 4; a sliding plate 12 slidably sleeved on the third lead screw 11, and the sliding plate 12 is fixedly connected to the placing rack 5; two nuts 13 threadedly installed on the third lead screw 11, and the two nuts 13 respectively abut against the two side walls of the sliding plate 12.

[0035] In this embodiment, when it is necessary to adjust the use height of the positioning block 6, loosen the two nuts 13, adjust the use height of the sliding plate 12 on the third lead screw 11. After adjusting the position, rotate the two nuts 13 again to abut against the two side walls of the sliding plate 12, so as to fix the sliding plate 12 after adjusting the position, thereby adjusting the use height of the positioning block 6, so that the positioning block 6 can better clamp and fix the outer wall of the ceramic workpiece.

[0036] In a further preferred embodiment of the present utility model, protective pads are provided on both the clamping block 2 and the positioning block 6.

[0037] In this embodiment, the outer wall of the ceramic workpiece can be protected by the protective pad, preventing the workpiece from being worn.
