Description
Technical field
The utility model relates to a kind of machining equipment, is specifically related to a kind of press machine draw bar fastener, is suitable for the fastening installation of bottom locking nuts such as various large-scale pull bars, pillar type column, belongs to the Machining Technology field.
Background technology
At present, when hydraulic press pull bar or pillar type column bottom locking nut are installed, be that the assembler is placed on a fixed pan with locking nut mostly; By suspending bars or the pillar type column of having driven a vehicle; Behind the artificial centering screw thread, rely on workman's the revolving force and the connection power of supporting force and screw thread, locking nut is screwed.So, during beginning sword screw thread, be prone to produce deflection, strengthened workman's installation difficulty; And thread connection causes thread stripping easily and pulls when initial, influenced the production cycle, and production cost improves.
Summary of the invention
The purpose of the utility model is for overcoming the weak point of above-mentioned prior art; A kind of press machine draw bar fastener is provided; This device comprises and carries the facing head be mounted the workpiece locking nut, in thrust ball bearing is housed, and cooperate supporting by slip blade and back nut; Be connected with support through spring, the upper end is fixing and spacing through locknut.This apparatus structure is simple, is easy to installation and maintenance, is applicable to that the installation of most of hydraulic press bottom locking nut is fastening.
The utility model is realized with following technical scheme: a kind of press machine draw bar fastener; This device includes turntable; Pull bar is arranged on the turntable, and pull bar is fixed on the turntable through locking nut, it is characterized in that: in the described turntable thrust ball bearing is housed; Slip blade and holding nut are arranged below the thrust ball bearing), support is connected with slip blade through spring; The upper end of described support is connected with slip blade through locknut.
Described slip blade is connected with support through spring, all is welded with the spring positioning sleeve on slip blade and the support.
Be welded with square lead in the middle of the described support, its upper end is fixed through locknut, and spacing to slip blade.
The utility model has the advantages that: this apparatus structure is simple, compact, and easily manufactured, easy operating.Fully satisfying under the precondition of using, not only reducing requirement largely, and reduced, improving production efficiency because of assembling the improper percent defective that causes to installer's technology.And be suitable for the application that bottom locking nuts such as various large-scale pull bars, pillar type column are installed.
