Detailed Description

The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.

As shown in figures 1-5, the utility model relates to a positioning and processing clamp for a semiconductor connecting rod tool, which comprises a base 1, wherein a counter bore for fixedly connecting with a machine tool workbench is arranged on the base 1, a positioning backer 2 with a square structure is arranged on the base 1, two groups of support components which are arranged oppositely are arranged at the left side and the right side of the positioning backer 2, each group of support components comprises a fixed support seat 3 and a limit component 4, the limit components 4 are distributed diagonally, the limit device 42 comprises a limit rod 41 and limit devices 42 arranged at the upper end and the lower end of the limit rod 41, the limit device 42 is provided with a limit groove along the distribution direction of the support components, the top end of the limit rod 41 is provided with a cylinder 43 for driving the limit rod 41 to move along the limit groove, a plurality of clamping components 5 for clamping and processing workpieces are fixed on the fixed support seat 3 through bolts in sequence, the clamping assembly 5 comprises a left supporting block 51, two parallel central supporting blocks 52 and a right supporting block 53 which are arranged in the same plane, and the flatness is required to be within 0.03 mm; two rows of threaded holes for being used for being connected with the fixed supporting seat 3 are arranged on the left supporting block 51 and the right supporting block 53 at positions which avoid the placement of a workpiece to be processed, and the threaded holes are horizontally distributed and used for clamping the workpiece and limiting the freedom degree of the vertical movement of the workpiece; after the workpiece is clamped and compressed, the upper surface of the workpiece can be parallel to a main shaft of the machine tool;

the left supporting block 51 and the right supporting block 53 are provided with bosses for placing workpieces to be processed and the central supporting block 52, after the workpieces to be processed are placed on the left supporting block 51 and the right supporting block 53, the two central supporting blocks 52 are kept away from the parts of the workpieces to be processed, and then the parts are fixed on the fixed supporting base 3 through the threaded holes of the central supporting block 52, so that the freedom degree of axial movement of the workpieces is limited, and the stability of clamping is ensured.

After a workpiece to be processed is fixed on the clamping assembly 5, a positioning rod is pushed forwards under the action of the air cylinder 43; after the workpiece is placed, the other positioning rod pushes forwards from the other side through the air cylinder 43, so that the clamping assembly 5 is completely attached to the front positioning rod, and the freedom degree of the left and right movement of the clamping assembly 5 is limited. Then, the two positioning rods are retracted inwards through the pulling back of the air cylinder 43, so that no tool interference is caused when the workpiece is machined, and the two side surfaces of the workpiece can be conveniently machined.
