Abstract
The invention discloses an eccentric disc drill clamp and relates to the technical field of mechanical machining. The eccentric disc drill clamp comprises an eccentric shaft which is installed on a bearing seat in a penetration mode; one end of the eccentric shaft is provided with an eccentric positioning shaft portion and a screw rod portion; the eccentric positioning shaft and the screw rod portion are in ladder connection; a first pressing plate and a locking nut sequentially sleeve the screw rod portion; the other end of the eccentric shaft is provided with a limit boss; the limit boss is provided with three projections extend out along the radial direction; an included angle between every two adjacent central lines of the projections is 120 degrees; the bearing seat is provided with grooves which are corresponding to the projections; the external end of the limit boss is provided with a second pressing plate. Compared with the prior art, according to the eccentric disc drill clamp, the operation is simple and convenient, the production efficiency is high, and the labor intensity is low.
Description
Technical field
The present invention relates to Machining Technology field, especially a kind of drill jig of radial hole processing on eccentric disc.
Background technology
The radial hole processing of eccentric disc is normally carried out on drilling machine, and eccentric disc 9 as shown in Figure 1 has an eccentric orfice and has been disposed radially three radial hole 9-1, and the angle of adjacent two radial hole 9-1 center lines is 120 degree.Owing to there is no special eccentric disc drill jig, with clamping plate eccentric disc clamping is fixed on drilling machine and processes, after processing a radial hole, take clamping plate apart eccentric disc rotation 120 degree again clamping is fixed, reprocess another radial hole, production efficiency is low, and labour intensity is large.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of eccentric disc drill jig, to solve the inefficient problem of eccentric disc processing.
In order to solve the problem, the technical solution used in the present invention is: this eccentric disc drill jig, include the eccentric shaft be installed on supporting base, one end of described eccentric shaft has eccentric locating shaft portion and is the threaded shank that ladder links with described eccentric locating shaft portion, described threaded shank is set with the first pressing plate and locking nut successively, the other end of described eccentric shaft is provided with positive stop lug boss, described positive stop lug boss is provided with three projections extended radially, and the angle of adjacent two described protrusion center line is 120 degree; Described supporting base is provided with the groove corresponding with the described projection of described positive stop lug boss, and the second pressing plate is equipped with in the outer end of described positive stop lug boss.
In above-mentioned eccentric disc drill jig technical scheme, technical scheme can also be more specifically: the outer end of the described positive stop lug boss of described eccentric shaft is provided with cavity, by jointed shaft, handle is housed in described cavity.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is when processing eccentric disc, eccentric disc drill jig is arranged on the workbench of drilling machine, eccentric disc is sleeved on eccentric locating shaft portion, eccentric disc is tightened up with the first pressing plate and locking nut, a radial hole can be processed, after processing this radial hole, unclamp bolt, take off the second pressing plate, eccentric shaft is pulled vertically, the projection of positive stop lug boss is separated with the groove of supporting base, eccentric shaft turns 120 degree, the projection of positive stop lug boss snaps in the groove of supporting base again, load onto the second pressing plate, reprocess another radial hole, simple to operation, production efficiency is high, labour intensity is low.
2, the outer end of the positive stop lug boss of eccentric shaft is provided with cavity, and by jointed shaft, handle is housed in cavity, facilitate eccentric rotation axis, structure is simple.
