Background technology
Find no similar device on automatic and semi-automatic tapping machine in the market, when dislocation, complete mainly by manual work；Hydraulic motor and tapping-head are mainly directly fixed on support by device at present, during dislocation, need to manually firmly grasp parts and be adjusted, when artificial dislocation, easily come off, even cause personal injury.
Utility model content
The purpose of this utility model is to provide a kind of tapping machine tapping-head anti-drop device, with the deficiency overcoming prior art to exist, this utility model is prevented from tapping-head when tapping-head operates conversion in the horizontal direction and comes off, apparatus structure is ingenious, design compact conformation, operation is changed conveniently, and safety is high.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of tapping machine tapping-head anti-drop device, is provided with the bearing of spline including one end, and bearing spline lower end is provided with cannelure；Carrier exterior is provided with sleeve, is provided with anti-spline pad in the cannelure of bearing, and anti-spline pad is provided with positive spline pad, is sequentially provided with spring, gripping pad and the locking nut for fastening above positive spline pad.
Further, described bearing tail end is provided with the threaded rod of the fastening coordinated with locking nut.
Further, the key shoulder for limiting anti-spline pad it is provided with in described sleeve.
Further, described sleeve lower end is provided with side plate, and sleeve side is additionally provided with the clamping fanning strip for fastening and clamping lever.
Further, being provided with projection in described anti-spline pad, positive spline pad is provided with the boss locked with anti-spline pad and bearing spline fitted.
Compared with prior art, this utility model has a following useful technique effect:
This utility model is by utilizing cooperating of anti-spline pad and positive spline pad, prevent bearing coming off at vertical direction, when can easily realize preventing tapping-head from operating conversion in the horizontal direction, tapping-head comes off, spring is prevented from the yielding of positive spline pad, and make gripping pad realize appliance for releasing single when unclamping locking nut to play action, apparatus structure is ingenious, design compact conformation, operation is changed conveniently, and safety is high.
