Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 to 3, a polishing apparatus for processing a communication terminal includes:

the bottom plate 1, the said bottom plate 1 plays a role of supporting;

the bracket 2 is fixedly arranged on the bottom plate 1;

a connecting rod 8 is fixedly connected to the bottom of the middle of the support 2, a rotary table 6 is arranged at the bottom end of the connecting rod 8, a first bearing 7 is fixedly embedded in the center of the top of the rotary table 6, and the bottom end of the connecting rod 8 is fixedly inserted into the first bearing 7;

four polishing disks 10 are distributed at equal angles on the periphery below the rotating disk 6, and the four polishing disks 10 are different in size.

As shown in fig. 3, the polishing disc 10 is connected to the bottom end of the rotating pipe 9, the inner wall of the rotating pipe 9 is provided with threads, and the rotating pipe 9 movably penetrates through the rotating disc 6.

By adopting the scheme, the rotating pipe 9 movably penetrates through the rotating disc 6, so that the rotating pipe 9 can be rotated on the rotating disc 6, the rotating pipe 9 is tightly rotated on the rotating rod 5, and the connection work between the polishing disc 10 and the rotating rod 5 is realized.

As shown in fig. 1, a fixed disk 3 is installed on the top end of the support 2, a motor 4 is arranged on the top end of the fixed disk 3, a rotating rod 5 is fixedly connected to an output shaft of the motor 4, the rotating rod 5 penetrates through the fixed disk 3 and the support 2, threads are arranged on the bottom end of the rotating rod 5, and the bottom end of the rotating rod 5 rotates into a rotating pipe 9.

By adopting the scheme, the rotating rod 5 can be driven to rotate under the action of the motor 4.

As shown in fig. 3, a cavity 11 is formed in the fixed disk 3, the rotating pipe 9 movably penetrates through the cavity 11, a second bearing 12 is fixedly sleeved on a portion of the rotating pipe 9 penetrating through the cavity 11, and the second bearing 12 is clamped and sleeved in the cavity 11.

Through adopting above-mentioned scheme, the height of cavity 11 is greater than the height of second bearing 12, when rotating the rotating tube 9 on carousel 6, can be with rotating tube 6 upwards tighten to bull stick 5 on, the card cover of the second bearing 12 activity that fixed cover was established on the rotating tube 9 simultaneously is in cavity 11, prevents that rotating tube 9 and polishing dish 10 from taking place the condition that drops.

As shown in figure 1, the tightening direction of the internal thread of the rotating pipe 9 is the same as the rotating direction of the rotating rod 5 connected with the output shaft of the motor 4.

Through adopting above-mentioned scheme, when motor 4 drives bull stick 5 and rotates, because the tight direction of commentaries on classics of bull stick 9 internal thread is the same with bull stick 5 rotation direction, just can not take place the not hard up problem of commentaries on classics pipe 9 when bull stick 5 rotates like this.
