Description

A thin plate drilling jig

technical field

The utility model relates to the field of mechanical manufacturing, in particular to a thin plate drilling jig.

Background technique

Fixtures are used in the process of mechanical manufacturing to fix the processing object so that it occupies the correct position to accept construction or

detection device. For the drilling of thin-plate workpieces, the thin-plate workpieces are often placed on the machine tool for drilling, but the clamping of the workpiece will not be firm, and it will also cause processing deformation and other effects on the workpiece. To sum up, improving the existing fixtures for thin-plate workpieces to increase their versatility is the key to improving the technology in this field.

Utility model content

A thin plate drilling jig mainly includes a base, a clamping device, a pressing device, a positioning block, a U-shaped groove, a T-shaped block, a column, a drilling template and a drill sleeve; the clamping device includes a support plate, a guide rod , a manual screw and a baffle; the pressing device includes a cylinder, a telescoping rod, a pressing rod and a side plate.

A positioning block is arranged at the left position in the middle of the clamp base, and the U-shaped groove is fixed on the positioning block. When drilling, the workpiece is positioned on the U-shaped groove, and the chips enter the U-shaped groove to complete the drilling of the workpiece.

The left and right support plates of the clamping device are welded on the fixture base, the right side baffle is fixed on the right side support plate, and the left side baffle is fixed on the manual screw; when the workpiece is positioned, make the workpiece close to the right side baffle After the positioning is completed, turn the manual screw to make the left baffle cooperate with the right baffle along the guide rod to clamp the workpiece.

The side plate of the clamping device is welded on the fixture base, and after the clamping device clamps the workpiece, the cylinder pushes the expansion rod to drive the compression rod to compress the workpiece.

The drilling template and the column, and the column and the T-shaped block are connected by bolts.

The T-shaped block slides in cooperation with the T-shaped groove on the fixture base, and when the drilling template reaches the designated drilling position, the T-shaped block is positioned by the positioning pin, so that different positions of the workpiece can be drilled.

detailed description

A thin plate drilling jig mainly includes a base 1, a clamping device, a pressing device, a positioning block 15, a U-shaped groove 14, a T-shaped block 12, a column 10, a drilling template 7 and a drill sleeve 6; the clamping The device comprises a left side support plate 16, a guide rod 17, a manual screw rod 18, a left side baffle plate 19, a right side support plate 9, and a right side baffle plate 8; 4 and side panels 5.

The center of the clamp base 1 is provided with a positioning block 15 on the left, and the U-shaped groove 14 is fixed on the positioning block 15. When drilling, the workpiece is positioned on the U-shaped groove 14, and the chips enter the U-shaped groove 14 to complete the process. Drilling of workpieces.

The left side support plate 16 and the right side support plate 9 of the clamping device are welded on the fixture base 1, the right side baffle plate 8 is fixed on the right side support plate 9, and the left side baffle plate 19 is fixed on the manual screw rod 18; When the workpiece is positioned, make the workpiece close to the right side baffle plate 8, after the positioning is completed, rotate the manual screw rod 18 to make the left side baffle plate 19 cooperate with the right side baffle plate 8 to clamp the workpiece along the guide rod 17.

The side plate 5 of the clamping device is welded on the clamp base 1, and after the clamping device clamps the workpiece, the cylinder 2 pushes the telescopic rod 3 to drive the compression rod 4 to compress the workpiece.

The drilling formwork 7 and the column 10, and the column 10 and the T-shaped block 12 are connected by bolts.

The T-shaped block 12 slides with the T-shaped groove on the fixture base 1.
