Description
Technical field
The utility model belongs to mechanical manufacturing field, a kind of specific pin.
Background technology
Usually need to use Standard pallet in the manufacturing process of accurate miniaturized component, Standard pallet is square or rectangular
Shape.Existing Standard pallet is to process multiple holes by milling machine or grinding machine in a block of metal plate to form, in above-mentioned processing technology
In, core element is：How the appearance and size of monolithic steel plate and the precision of position of positioning hole that process is ensured.
The lathes such as milling machine, grinding machine often process hole class workpiece, and mostly with round orifices orientation, workpiece is with round orifices orientation mostly using fixed
The heart positions, i.e., positioning datum is the axis in hole.Alignment pin positions hole type parts frequently as the parts of the lathes such as milling machine, grinding machine
Auxiliary completes hole type parts processing.At present, the alignment pin usually inserted workpiece on lathe, is matched somebody with somebody by shop bolt and workpiece
Close to realize centering positioning.But positioning hole aperture on workpiece is excessive, the mismachining tolerance of alignment pin itself and alignment pin work
Abrasion during work can make the axis of positioning datum offset bore, impact position precision, so as to influence the machining accuracy of workpiece.
In addition, for being welded using multilayer disk body and to form the equipment of Standard pallet, it can also have the problem of extra：
Multi-layered product needs are positioned using shared pin hole simultaneously when, the size of multi-layered product positioning hole and position may be because that every layer adds
Work or design reasons and difference, i.e., 0.03cm error is had between each hole；For it is such the problem of in the prior art can only
Using the standard cylindrical pin of matching minimum-value aperture, its caused bigger error.
Utility model content
The purpose of this utility model is to provide the pin that a kind of positioning precision is high, easy to use and fast locating speed.
In order to achieve the above object, scheme is used by the utility model：
A kind of pin, it includes handle, locating dowel and guide portion, described locating dowel one end with handle is concentric is fixedly connected,
The other end is connected to the guide portion with inclined side；The locating dowel is by post core and some positioning being arranged on post outer core
Bar is formed, and positioning strip is made and detachably connected with post core of elastic material；The positioning strip is on post outer core along post
Core axial direction straight line sets or spirally set along post outer core, between each positioning strip or between same positioning strip different piece
With gap, positioning strip is provided with longitudinal seam, and the longitudinal seam is set along positioning strip bearing of trend.
The pin of the program by reforming the structure of locating dowel, if traditional cylindrical column is changed be with
The Heavenly Stems and Earthly Branches support the structure of positioning strip, and then reduce contact area, convenient installation, and have certain gap between positioning strip and can permit
Deformation certain Xu Qiyou is to match the positioning hole of reduced size.It is slightly smaller that maximum sized positioning hole in multi-layered product is pressed during use
0.01cm specification configures above-mentioned positioning strip external diameter, for larger positioning hole its it is of course possible to directly position fixation, it is and right
In slightly smaller positioning hole, it can also realize preferable fixation and locating effect after hole extruding is positioned, so as to greatly
Improve positioning precision.
Preferably, the positioning strip trapezoidal shape on section.
Preferably, the pin is also warned device including deviation, and deviation device of warning includes power supply, control module, distance
Sensor and module of warning, range sensor are located at the gap location of positioning strip, and module of warning is arranged in guide portion or it is added
Work is guide portion.Deviation warn device can with perceptual positioning post to the distance between every layer of product, when positioning strip serious wear or
Positioning strip installation site will cause positioning hole and pin decentraction when problematic, and early warning can be sent by now deviateing device of warning
Signal and avoiding continues scale error caused by processing in the case of unwitting.
Further, the module of warning is warning lamp and/or loudspeaker.
Further, each pin only sets range sensor and module of warning when the pin multiple support the use,
Power supply and control module share a set of.Structure can be simplified by, which so setting, reduces cost.
Pin of the present utility model is changed traditional cylindrical column for tool by reforming the structure of locating dowel
There is the structure of some support positioning strips, and then reduce contact area, convenient installation, and be greatly enhanced positioning precision；Coordinate
Deviate device of warning can then to warn the very first time of mistaking is located, avoid causing mismachining tolerance because of position error.

Wherein, 1, handle, 2, locating dowel, 3, guide portion, 21, post core, 22, positioning strip, 23, longitudinal seam.
Embodiment
The technical solution of the utility model is further elaborated with reference to embodiment：
A kind of pin, it is made up of handle 1, locating dowel 2 and guide portion 3, and described one end of locating dowel 2 and handle 1 are with one heart
It is fixedly connected, guide portion 3 is arranged at the other end of locating dowel 2 and with inclined side for conveniently connection during installation；It is described
Locating dowel 2 is made up of post core 21 and some positioning strips 22 being arranged on post outer core, and the positioning strip 22 is on section in ladder
Shape, it is slightly larger to contact side with post core 21；Positioning strip 22 is made and detachably connected with post core 21 using elastic material, with side
Just changed in 22 serious wear of positioning strip, positioning strip 22 is provided with longitudinal seam 23, and the longitudinal seam 23 prolongs along positioning strip
Direction setting is stretched, to improve the necessary deformation quantity in engagement process of positioning strip 22；The positioning strip 22 edge on post outer core
The axis direction of post core 21 point-blank sets or spirally set along the outer wall of post core 21, and between each positioning strip or same positioning strip is different
There is certain gap, deformation of the gap on the one hand for positioning strip 22 in use provides space, another between part
Aspect can also provide space for the setting of range sensor.
