Abstract
The utility model relates to a positioning frock for installing steel ball, which comprises a guide rod, and one end of the guide rod is provided with a through hole which can be passed by the steel ball. A guide incline surface with the width same as the diameter of the through hole, which is connected with the through hole and along the axial direction of the guide rod. The guide rod and the workpiece diameter or section size needing to install the steel ball is the same or corresponding. The guide incline surface can make the steel ball gradually pressed to the steel ball hole with spring, and the workpiece enters steel ball position allowing installing steel ball positioning until the ring shaped groove on the workpiece to make the steel ball entered. The utility model has the advantages that: the guide incline surface can make the steel ball gradually pressed to the steel ball hole with the spring, which avoids the troubles that: the steel ball needs to be pressed by manpower, then the operation component is knocked on, then the steel ball gradually falls to the ring shaped groove, which makes the installation convenient and reliable, and the utility model with simple structure is easy in manufacture, thereby bringing great convenience for producing and assembling or maintenance.
Description
Technical field
The utility model relates to machine-building.
Background technology
For executive component mechanically, often adopt steel ball to locate as operating axis, operating grip and so on, with restriction or affirmation different operating position, just between aforesaid operations element and its matrix that relatively moves or pedestal, a steel ball is set, establish several pits on the executive component, establish the hole that can hold steel ball and eject steel ball and spring on the pedestal, the position of the executive component that different pit correspondences requires in advance; Above-mentioned pit generally makes cannelure on axle; This method is simple and reliable, the location is accurate, easy to manufacture, be exactly that installation is a bit not too convenient, when assembling, when keeping in repair etc. such as production, because the effect steel ball of spring can not enter in the hole automatically, after needing manually steel ball to be depressed, knock executive component then, make steel ball fall into pit or cannelure, both time-consuming, also unreliable, give to produce and assemble or keep in repair and cause very big difficulty.
The utility model content
In order to solve the problem that above prior art exists, the purpose of this utility model is: a kind of installation steel ball positioning tool that is used for a class is provided, makes easy to assembly.
In order to achieve the above object, installation steel ball positioning tool of the present utility model comprises guide rod, and an end of its guide rod has can be by the through hole of steel ball, joins with this through hole and width is arranged with the identical lead-in chamfered of this through-hole diameter along the axis direction of guide rod.Guide rod is identical or suitable with the diameter of work or the sectional dimension that need the installation steel ball, and lead-in chamfered can be pressed into steel ball in the steel ball hole of spring gradually, and workpiece enters the steel ball position with the steel ball positioning tool is installed, and the cannelure on workpiece enters steel ball.
Above-mentioned installation steel ball positioning tool can also have chamfering on guide rod, the other end of guide rod can have handle.
Lead-in chamfered the utility model has the advantages that: owing to can be pressed into steel ball in the steel ball hole of spring gradually, after having avoided needing manually steel ball to be depressed, knock executive component then, just make steel ball fall into the trouble of cannelure, make easy to assembly, reliable, its simple in structure being convenient to is made, and gives to produce and assembles or keep in repair and bring great convenience.
