Special drilling machine for processing porous gear

Abstract

The invention relates to a special drilling machine for processing a porous gear. A lifting frame can lift; a liquid storing tank is formed in the middle of a cooling bedplate; a through hole is formed at the bottom of the liquid storing tank; a drill bit is aligned with the through hole; the cooling bedplate is sleeved on a slide rod; one end of a spring is pressed on a gearbox sleeve plate; the other end of the spring is pressed on the cooling bedplate; the upper part of the slide rod is fixed on the gearbox sleeve plate; a gear clamp is fixed on an operation platform; the gear clamp is composed of a central positioning pin, a positioning screw rod and a screw rod fixing block; the central positioning pin is located right under a rotating shaft of a drilling motor; the positioning screw rod is screwed on the screw rod fixing block; a plurality of drill bit matched through holes are formed on the periphery of the central positioning pin; the drill bit matched through holes are aligned with the drill bits; and a cooling liquid outlet pipe is aligned with the liquid storing tank. The special drilling machine can be used for drilling a plurality of small holes on a gear at one time; the production efficiency is increased; a gear fixing mode during a processing process and a structure are simple; the use is convenient; the reuse amount of the cooling liquid is reduced; and the production cost is lowered.

Description

Technical field: [0001] The invention relates to the technical field of gear production, in particular to a special drilling machine for porous gear processing. Background technique: [0002] In the production process of gears, it is necessary to drill holes for gears. Generally, gear manufacturers use ordinary drilling machines to drill holes for gears. Its weak point is: 1, ordinary drilling machine can only drill one hole on the gear at one time, then have to adjust the gear or move the drill bit position and drill the second hole again, the production efficiency is low, the number of operations is frequent, and it is not convenient enough to use. 2. Ordinary drilling machines need to continuously add coolant to the drill bit and gear during the drilling process, and the coolant is relatively large when used. 3. Ordinary drilling machines do not have special jigs for fixing gears, and the gear positioning is not convenient enough when the gears are drilled. Invention c...

Problems solved by technology

Its disadvantages are: 1. Ordinary drilling machines can only drill one hole on the gear at one time, and then have to adjust the gear or move the position of the drill bit to drill the second hole. The production efficiency is low, the number of operations is frequent, and it is not convenient to use.

2. Ordinary drilling machines need to continuously add coolant to the drill bit and gear during the drilling process, and the coolant is relatively large when used.

3. Ordinary drilling machines do not have special fixtures for fixing gears, and the positioning of gears is not convenient enough when drilling gears
