Abstract
The utility model relates to a flywheel housing locating taper pin, which comprises a pin body. The utility model is characterized in that a locating plug pin matched with a locating plug hole on a workbench is arranged at the lower part of the pin body and the locating plug pin is cylindrical; a locating pin is arranged at the central part of the pin body, matched with the locating hole of the workpiece and used to accurately locate the workpiece. The side wall of the locating pin is a reverse tapered face. The utility model has the advantages that the workpiece can be accurately located, the location is firm, the disassembling and the assembling are convenient and no tapered hole is required to be machined on the workbench.
Description
Technical field
The utility model relates to a kind of alignment pin, specifically, relates to a kind of bell housing location taper pin.
Background technology
When workpiece such as bell housing carry out machining on workbench, need alignment pin that it is positioned usually, to guarantee that processing operation can finish smoothly.Traditional alignment pin is the metal cartridge of a cylindrical shape, and this alignment pin can not precisely be located workpiece, also is not easy to dismounting.At the defective of traditional alignment pin, people have worked out a kind of taper pin, and promptly sidewall is the alignment pin of the conical surface.This taper pin can be controlled the degree of tightness of assembling, can precisely locate workpiece, and be convenient to dismounting.But, use this taper pin location, need on workbench, add the taper hole that cooperates with it down, very trouble.And this taper pin comes off in the process of using easily.
Summary of the invention
The purpose of this utility model provide a kind of can to workpiece precisely location, firm position, be convenient to dismounting, need not on workbench the bell housing location taper pin of processing taper hole.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of bell housing location taper pin comprises shank, it is characterized in that: but the bottom of shank is the fastening screw of positioning jack on the cooperating platform, cylindrical shape; The middle part of shank is the alignment pin that cooperates with the locating hole of workpiece, workpiece precisely can be located, and its sidewall is an inverted cone surface.
Be provided with the transition cylinder between described fastening screw and the alignment pin, cylindrical shape, the diameter of its cross section are less than the diameter of alignment pin bottom surface, greater than the diameter of fastening screw cross section.
The top of described alignment pin is provided with handle, cylindrical shape.
The outer surface of described handle is provided with anti-skidding decorative pattern.
Described handle, alignment pin, transition cylinder and fastening screw can be made from top to bottom and become one, and perhaps are fixedly connected sequentially from top to bottom together, and their axle center is on same straight line.
Owing to adopted above-mentioned technical scheme, the utility model has the advantages that:
1, fastening screw is a cylindrical shape, need not to process on workbench taper hole, and the location is more firm;
2, the sidewall of alignment pin is an inverted cone surface, can control the degree of tightness of assembling, can precisely locate workpiece, and be convenient to dismounting;
3, be provided with the transition cylinder, can play the effect of reinforcement;
4, be provided with the handle that outer surface has anti-skid design, easy disassembly.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Accompanying drawing is the structural representation of shank among the utility model embodiment.
The specific embodiment
A kind of bell housing location taper pin comprises shank.As shown in drawings, but the bottom of shank is the fastening screw 4 of positioning jack on the cooperating platform, cylindrical shape.The middle part of shank is the alignment pin 2 that cooperates with the locating hole of workpiece, workpiece precisely can be located, and its sidewall is an inverted cone surface.Be provided with transition cylinder 3 between fastening screw 4 and the alignment pin 2, cylindrical shape, the diameter of its cross section are less than the diameter of alignment pin 2 bottom surfaces, greater than the diameter of fastening screw 4 cross sections.The top of alignment pin 2 is provided with handle 1, cylindrical shape.The outer surface of handle 1 is provided with anti-skidding decorative pattern.
When making, handle 1, alignment pin 2, transition cylinder 3 and fastening screw 4 can be made from top to bottom and become one, also they can be fixedly connected sequentially together from top to bottom, but the axle center that will guarantee them is on same straight line.
