Abstract
The utility model discloses a device for drilling central holes, and belongs to the technical field of technical machining tools. A support plate is mounted and fixed on the plane of the upper end of a self-centering three-jaw chuck through two or more positioning pins. A guide sleeve is mounted and fixed at the common central portion of the support plate and the three-jaw chuck. The device has the advantages of low investment cost, convenience in movement and adaptability to shaft parts in need of on-site maintenance.
Description
Technical field
The present invention relates to a kind of mechanical processing technique frock, be specifically related to a kind of centering device, belong to mechanical processing technique frock technical field.
Background technology
In the mechanical processing process of shaft-like workpiece, generally will be in advance at the two ends of axle drill centers the benchmark as processing, existing drill centers generally need to adopt special drill centres machine tool, have advantages of that precision is higher although adopt special drill centres machine tool to drill centre bore,, this kind equipment generally has the higher defect of investment, simultaneously, because this kind equipment is generally fixed installation, so, be not suitable for being applied to the axial workpiece that some need field maintenance.
Summary of the invention
The object of the invention is to: for existing above-mentioned defect in drill centers process in the mechanical processing process of existing shaft-like workpiece, the invention provides a kind of simple and reliable, cost of investment is lower, the convenient mobile and on-the-spot a kind of centering device using.
A kind of centering device of the present invention, it is made up of commercially available standard three-jaw self-centering chuck, alignment pin, gripper shoe, fairlead, it is characterized in that: the upper port plane at three-jaw self-centering chuck is installed and fixed a gripper shoe with more than two or two alignment pins, install and fix a fairlead at the common center position of gripper shoe and scroll chuck, the pilot hole axle center of described fairlead overlaps with centering scroll chuck axial line.The present invention in use, utilizes centering scroll chuck three jaws to be clamped in the position, one end of axle, and the drill bit of electric hand drill bores to workpiece from fairlead endoporus, and the hole bored is just in the center, end of axle.
Beneficial effect: the process by structure principle chart of the present invention and use can find out, the present invention have cost of investment lower, conveniently moving, be suitablely applied to the axial workpiece advantage that some need field maintenance.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present invention;
Shown in figure: 1, three-jaw self-centering chuck; 2, alignment pin; 3, gripper shoe; 4, fairlead.
The specific embodiment
The commercially available standard three-jaw self-centering chuck (1) of employing standard, install and fix a gripper shoe (3) at more than two or two alignment pin for upper port plane (2) of three-jaw self-centering chuck (1), install and fix a fairlead (4) with the common center position of three-jaw self-centering chuck (1) in gripper shoe (3), the pilot hole axle center of fairlead (4) is overlapped with three-jaw self-centering chuck (1) axial line.In use, (10 3 jaws are clamped in the position, one end of axle, and the drill bit of electric hand drill bores to workpiece from fairlead (4) endoporus, and the hole bored is just in the center, end of axle to utilize centering scroll chuck.
