Description
Technical field
This utility model belongs to powder metallurgical technology, particularly relates to the plug anti-rotation device of a kind of powder metallurgy.
Background technology
In the design process of powder metallurgy, in general the material price of plug is higher, in order to make the making work of plug
Skill is simpler and material cost to be saved, and conventional method is plug to be split as rod head and takes over the baton, with screw by core
On club head is fixed on and takes over the baton, and when this design needs to dismantle rod head in process of production, it is necessary to whole screws and with
The bottom punch of cooperation disassemble, waste time and energy, otherwise when dismantling rod head screw, take over the baton can along with rotating together,
It is difficult to screw to do to ease up.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and provides a kind of anti-rotational dress of powder metallurgy plug
Put, thus realize preventing plug from rotating, convenient disassembly.In order to achieve the above object, technical solutions of the utility model are as follows:
A kind of powder metallurgy plug anti-rotation device, including pedestal and the plug being located on described pedestal；Described plug bag
Include take over the baton, be fixedly connected on described in take over the baton the rod head at top, described in the bottom taken over the baton be provided with the first convex of annular step scalariform
Platform and the second boss, described second convex edge of table is provided with the first pin hole of half hole wall, described pedestal is fixedly connected with ring
The gland of shape, described in take over the baton and be socketed in described gland, the inner ring of described gland is provided with and the described second corresponding cooperation of boss
The protuberance abutted, is provided with the second pin hole in described gland, the top of described second pin hole is that described protuberance is located at by complete opening wall
In, the bottom of described second pin hole is that half hole wall is located at described inner ring edge, described gland and described taking over the baton and is worn by contact pin
Cross described first pin hole and the fixing connection of described second pin hole.
Concrete, described rod head is the body of hollow, described tubular body be screwed be connected to described in connect
Rod.
Concrete, described gland offers some installing holes, described gland is fixed through described installing hole by screw
It is connected to described pedestal.
Concrete, described second pin hole runs through described gland.
Compared with prior art, the having the advantages that of this utility model powder metallurgy plug anti-rotation device:
It is provided with the first pin hole of half bore bottom taking over the baton, gland makes the second pin hole of same diameter, contact pin is put into holes
In so that need in process of production spanner can be used very easily plug screw dismounting when changing rod head, and connect
Rod due to contact pin screens, will not concomitant rotation, the undershoot eliminating original dismounting gland and cooperating just can pull down core
The work of club head, time-consuming, simple and efficient to handle.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the structural representation that the present embodiment is taken over the baton；
Fig. 3 is one of structural representation of the present embodiment gland；
Fig. 4 is the two of the structural representation of the present embodiment gland；
In figure, numeral represents:
1 pedestal, 2 take over the baton, 21 rod head, 22 first installing holes, 23 first boss, 24 second boss, 25
One pin hole, 26 second installing holes, 3 glands, 31 second pin holes, 32 inner rings, 33 protuberances, 34 the 3rd installing holes.
Detailed description of the invention
Technical scheme in this utility model embodiment will be carried out clear, complete description below in conjunction with the accompanying drawings, it is clear that
Described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
Embodiment:
With reference to shown in Fig. 1-4, the present embodiment is a kind of powder metallurgy plug anti-rotation device, including pedestal 1 be located at base
Plug on seat 1；Plug includes taking over the baton 2, is fixedly connected on the rod head 21 at 2 tops of taking over the baton, take over the baton 2 bottom be provided with annular
Stair-stepping first boss 23 and the second boss 24, the edge of the second boss 24 is provided with the first pin hole 25 of half hole wall, pedestal 1
On be fixedly connected with the gland 3 of annular, taking over the baton 2 is socketed in gland 3, and the inner ring 32 of gland 3 is provided with relative with the second boss 24
Should coordinate the protuberance 33 of abutting, be provided with the second pin hole 31 in gland 3, the top of the second pin hole 31 is that protuberance is located at by complete opening wall
In 33, the bottom of the second pin hole 31 is that half hole wall is located at inner ring 32 edge, and gland 3 and taking over the baton 2 (is not shown in figure by contact pin
Go out) through the first pin hole 25 and the second fixing connection of pin hole 31.Second pin hole 31 vertically runs through gland 3.
Rod head 21 is the body of hollow, and rod head 21 is provided with the first installing hole 22, and taking over the baton 2 is provided with the second installation
Hole 26, rod head 21 is fixedly attached to the second installing hole 26 by screw through the first installing hole 22.
Offering four the 3rd installing holes 34 on gland 3, gland 3 is fixedly attached to through the 3rd installing hole 34 by screw
Pedestal 1.
During application the present embodiment, due to the first pin hole 25 being provided with half bore bottom 2 of taking over the baton, gland 3 make identical
Second pin hole 31 of diameter, puts into holes contact pin so that need to change during rod head 21 permissible in process of production
Use spanner plug screw dismounting very easily, and take over the baton 2 due to contact pin screens, will not concomitant rotation, eliminate and originally tore open
The undershoot of venting closure 3 and cooperating just can pull down the work of rod head 21, time-consuming, simple and efficient to handle.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into this practicality
Novel protection domain.
