Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to the drawings, a bonding pad attachment comprising: the adhesive disc comprises an adhesive disc body 1, a supporting block 2, a connecting block 3, a spring 4 and a top ball 5. The bonding disc body 1, the supporting block 2 and the connecting block 3 are coaxially arranged, so that parts do not shift in the machining process, and machining errors are avoided.
The adhesive disc body 1 can be made of aluminum material, so that the weight is reduced. The bonding disc body 1 is set to be a cylindrical rotary body, the lower surface of the bonding disc body 1 is bonded with a part to be polished, and four M10 thread grooves 11 are drilled on the upper surface of the bonding disc body 1 so as to be additionally provided with the connecting block 3. The thread groove 11 is matched with the screw 6, and the bonding disc body 1 is in threaded connection with the screw 6.
The supporting block 2 can be made of stainless steel materials, and the supporting block 2 is set to be a cylindrical revolving body. Supporting shoe 2 sets up on bonding dish body 1, and supporting shoe 2 passes through screw 6 with bonding dish body 1 to be connected, and screw 6 uses the center pin of bonding dish to be the axis and be annular array symmetry setting.
In order to adjust the relative position of the supporting block 2 and the bonding disc in the horizontal direction, four cross through holes 21 of 10mmX30mm are provided on the supporting block 2, the screws 6 are inserted into the bonding disc body 1 through the cross through holes 21, and the position of the supporting block 2 mounted on the bonding disc is adjusted through the cross through holes 21.
