[0022] Embodiment 1, by Figure 1-Figure 4 The utility model includes a pillar 1, the upper end of the pillar 1 is connected to a shaking table assembly 2, the upper end of the shaking table assembly 2 is provided with a metal cup 3, the metal cup 3 is provided with superhard material powder inside, the upper end of the superhard material powder is provided with an alloy sheet, and a vibrator 4 is installed on one side of the lower end of the shaking table assembly 2, and the shaking table assembly 2 is vibrated by the vibrator 4 so that the superhard material powder in the metal cup 3 is evenly spread on the lower end of the alloy sheet;

[0023] Specifically, the shaking table assembly 2 includes a tray 201, a cover plate 202 is connected to the upper end of the tray 201, a shell 203 is connected to one side end of the tray 201, a worm 204 is rotatably connected inside the shell 203, and the upper end of the worm 204 extends to the upper side of the shell 203 and is connected to a handle 205;

[0024] One end of the housing 203 is rotatably connected to a bidirectional screw rod 206, one end of the bidirectional screw rod 206 extends to one side of the housing 203 and is rotatably connected to the inner wall of the tray 201, one end of the bidirectional screw rod 206 extends to the inside of the housing 203 and is connected to a worm wheel 207, and the worm wheel 207 is meshed with the worm 204;

[0025] Both sides of the surface of the bidirectional screw rod 206 are symmetrically threaded with movable blocks 208, both sides of the movable blocks 208 are rotatably connected with connecting rods 209, one end of the connecting rods 209 on both sides are rotatably connected with cross plates 210, the upper ends of the cross plates 210 on both sides are connected with clamping pieces 211, and both sides of the lower ends of the cross plates 210 are connected with positioning blocks 212, and the positioning blocks 212 are penetrated by a light rod 213, and the light rod 213 is connected to the inner wall of the tray 201;

[0026] The clamping member 211 includes a support rod 2111 connected to the horizontal plate 210, an adjusting groove 2112 is symmetrically opened on one side of the upper part of the support rod 2111, a clamping block 2113 is provided on one side of the adjusting groove 2112, and the clamping block 2113 is threadedly locked by a bolt 2114 passing through the adjusting groove 2112;

[0027] The upper end of the cover plate 202 is provided with movable grooves 214 corresponding to the penetration positions of the support rods 2111 .

[0028] Working principle: When in use, place the sintering cup 3 between the clamping pieces 211 on the shaking table assembly 2, lay a layer of superhard material powder inside the metal cup 3, and then put in the alloy sheet. Preferably, the cross section of the alloy sheet is the same as or slightly larger than the cross section of the metal cup 3, and then fix the metal cup 3 with the clamping piece 211;

[0029] When clamping, the worm 204 is driven to rotate by rotating the handle 205, and the worm 204 is meshed with the worm wheel 207, so that the worm wheel 207 drives the bidirectional screw 206 to rotate.

After a period of vibration, the superhard material powder at the bottom of the metal cup 3 can be evenly spread under the alloy sheet under the action of the vibration force. The metal cup 3 is then removed and sintered to combine the superhard material powder with the alloy sheet. The superhard material powder is evenly spread through such vibration, thereby improving product quality.
