According to the reference ball tool, one end of the reference ball rod is connected into the tool body according to the heat expansion and cold contractionprinciple, errors caused by threaded connection are avoided, and the precision is high; and the reference ball rod and the tool body are detached simply, and the reference ball rod and the reference ball rod are convenient to replace.
Description
[technical field]
The present invention relates to field of machining, particularly relate to point middle ball work being used during a kind of machining
Tool.
[background technology]
In point, ball is again reference sphere, is the spherical tool of a kind of positioning, centering, applies in electro-discharge machining.
A current point middle ball instrument is typically from the purchase of EROWA company, expensive.In point, ball instrument is producing
Only deliver to EROWA company when abnormal change or directly scrap, therefore relatively costly.
Thus, in order to reduce cost, in electro-discharge machining, the ball instrument in simple point that can make uses.So
And, ball instrument in simple point, be use the mode of thread connect point tool body of middle ball instrument and point in
Club, ratio of precision is relatively low, and when using board C axle, ball center exists the excessive problem of deviation.
In view of this, it is necessary ball instrument in a kind of point of exploitation in fact, to solve ball instrument ratio of precision in above-mentioned point
Relatively low, the excessive problem of ball center's deviation.
[content of the invention]
Therefore, it is an object of the invention to provide ball instrument in a kind of point, in this point, the precision of ball instrument is high, ball
Centre deviation is little.
In order to achieve the above object, the present invention point in ball instrument, its for positioning on electro-discharge machining board,
Centering, in described point, ball instrument includes:
Fixture, its one end is fixed on electro-discharge machining board；
Tool body, which is column, and described tool body is one-body molded with described fixture, and described instrument is originally
One end of body is provided with receiving hole；
Club in point, which is cylinder, and in described point, one end of club is located in described receiving hole, described work
The diameter of club during the diameter of described receiving hole is slightly larger than described point after tool body heating；
Ball in point, it is located at the other end of club in described point.
It is preferred that the outer fixture without leave of described tool body tapers into a point direction for middle club.
It is preferred that described receiving hole is arranged by lapping mode.
It is preferred that the degree of depth of described receiving hole is less than or equal to 10 millimeters.
It is preferred that the material of club is wolfram steel in described point.
Compared to prior art, point middle ball instrument of the present invention, in dividing, one end of club is by using heat expansion
The principle of shrinkage is connected in described tool body, it is to avoid use the error that thread connects, and precision is high, spheroid
Precision reaches ± 0.001mm, when using board C axle, C axle ball center deviation in 0.002mm, and point in
Club is simple with tool body dismounting, is convenient for changing point middle club and point middle ball.
[brief description]
Fig. 1 illustrates the schematic perspective view of point middle ball instrument of the present invention.
Fig. 2 illustrates the decomposing schematic representation of point middle ball instrument of the present invention.
[detailed description of the invention]
Referring to shown in Fig. 1 and Fig. 2, it depicts the schematic perspective view of point middle ball instrument of the present invention respectively
And the decomposing schematic representation of point middle ball instrument of the present invention.
Point middle ball instrument of the present invention, it is for positioning, centering on electro-discharge machining board, in the present embodiment,
In described point, ball instrument includes:
Fixture 100, its one end is fixed on electro-discharge machining board, and described fixture 100 can be EROWA assembly；
Tool body 200, which is column, and described tool body 200 is one-body molded with described fixture 100,
One end of described tool body 200 is provided with receiving hole 210, and in the present embodiment, described receiving hole 210 is passed through
Lapping mode is arranged, and the degree of depth of described receiving hole 210 is less than or equal to 10 millimeters, described receiving hole 210
A diameter of 3.995 millimeters；
Club 300 in point, which is cylinder, and in described point, described receiving hole 210 is located in one end of club 300
In, club 300 during the diameter of described receiving hole 210 is slightly larger than described point after heating described tool body 200
Diameter, in the present embodiment, in described point, the material of club 300 is wolfram steel, club 300 in described point
A diameter of 4.0 millimeters；
Ball 400 in point, it is located at the other end of club 300 in described point.
Wherein, in order to increase the ability to bear of tool body 200, the intensity of described tool body 200 is strengthened,
The outer fixture without leave 100 of described tool body 200 tapers into a point direction for middle club 300.
In the present embodiment, point middle ball instrument of the present invention, by arranging the receiving hole 210 of tool body 200
A diameter of 3.995 millimeters, a diameter of 4.0 millimeters of club 300 in arranging point；Use heating gun to work
Tool body 200 is heated to 300 DEG C, and due to the principle expanded with heat and contract with cold, the diameter of described receiving hole 210 becomes
4.02 millimeters, the diameter of described receiving hole 210 is slightly larger than the external diameter of club 300 in described point；Will point middle ball
One end of bar 300 is located in described receiving hole 210, then cools down, also due to the principle of rising-heat contracting-cold,
