Car drum type brake gasket drilling device

Abstract

The invention discloses a car drum type brake gasket drilling device. A worktable is fixedly mounted on the top of a base, a rack is mounted on one side of the top of the worktable, an air cylinder isarranged on the bottom of the inner side of the top end of the rack, the bottom of the air cylinder is connected with a telescopic rod, the bottom of the telescopic rod is provided with a tool fixingsleeve, fixed bases are symmetrically mounted on the middle of the top end of the worktable, abutting blocks are connected to one ends of the tops of the fixed bases, fixed blocks are connected to the positions, corresponding to the abutting blocks, of the tops of the fixed bases, the surfaces of the fixed blocks are movably connected with clamping blocks, clamping grooves are formed in the clamping blocks, sliding grooves are symmetrically formed in the two ends of each clamping block, and screw rods are sleeved with the fixed blocks in a penetrating manner. Through screw rod feeding, the clamping blocks are extruded and clamp machining parts, the adjusting of the clamp position is improved, a placing hole is used for facilitating fixing of an arc gasket, stability during machining is ensured, and punching failures can be avoided.

Description

technical field [0001] The invention relates to the technical field of drum brake lining processing, in particular to an automobile drum brake lining drilling equipment. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. Usually, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes, blind holes, and replace special tools. , can be expanded, countersinked, reamed or tapped, etc. During the processing, the workpiece does not move, the tool moves, the center of the tool is aligned with the center of the hole, and the tool is rotated. For this reason, the Chinese patent discloses a drum type The drilling device for the brake lining, the application number is 201721231851.2, the patent is provided with a limit plate on the body, a...

Problems solved by technology

[0004] The invention provides an automobile drum brake lining drilling equipment, which can effectively solve the problem of using a spring and a push piece to fix the lining in the above-mentioned background technology, which cannot keep the arc-shaped lining stable during processing, resulting in drilling failure. Drilling failure will cause damage to the drill bit, and broken drill bits will cause damage to equipment and operators
