Abstract
The invention discloses a no-parking centering fixture. The no-parking centering fixture comprises a three-jaw centering chuck, a spring, a conical surface centering sleeve, a tooth shaft, a workpiece and a live center; the three-jaw centering chuck is connected with the tooth shaft, the tooth shaft is sleeved with the spring and the conical surface centering sleeve, the workpiece is sleeved out the conical surface centering sleeve and clamped by the live center; the workpiece comprises a cylinder hole and taper hole, the conical surface centering sleeve, is located at the opening of the cylinder hole, the tooth conical surface of the tooth shaft locates the taper hole surface. The no-parking centering fixture is simple in structure, exact in location, convenient in operation while guaranteeing the turning processing precision.
Description
Technical field
The present invention relates to the work piece holder technical field of machining, particularly relate to one and not stop centralizer.
Background technology
Excircle of workpiece part is applied in various plant equipment product.Outer circular Curve as shown in Figure 1, when turnery processing, needs bigger diameter end and miner diameter end to have higher axiality, therefore needs to use fixture.During turnery processing, the method usually adopted first processes its bigger diameter end, then with turnery processing upper end, bigger diameter end location.But clamp structure is in the past complicated, position error is large, so precision is lower, and clamping trouble, reduce production efficiency while adding operator's labour intensity, be not suitable for batch production.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides one and not to stop centralizer, can solve the problems of the technologies described above completely.
The technical scheme solved the problems of the technologies described above is as follows:
One is not stopped centralizer, comprise three-jaw centering chuck, spring, conical surface centring sleeve, tartar axle, workpiece and rolling center, described three-jaw self-centering chuck is connected with tartar axle, described tartar axle puts spring and conical surface centring sleeve, and in the outer cover of the conical surface centring sleeve workpiece, hold out against with rolling center, described workpiece comprises cylindrical hole and taper hole, described conical surface centring sleeve positioning cylinder aperture, the taper hole face, tartar conical surface location of described tartar axle.
The steel wire diameter of described spring is 1.5mm ~ 3mm, has enough thrust to make conical surface centring sleeve.
Conical surface centring sleeve is H7/f6 with coordinating of tartar axle, because the cylindrical hole on workpiece and taper hole are that same loam core casts out, axiality is better, so workpiece is when feeling relieved, with conical surface centring sleeve positioning cylinder aperture, with the taper hole face, tartar conical surface location of tartar axle, tartar part is also because rubbing action drives workpiece to rotate.
For improving the top contact to casting workpiece end face, by the top sphere wearing into SR2.5mm.
Structure of the present invention is simple, accurate positioning, ensures turnery processing precision, easy to operate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is by size Workpiece structure schematic diagram;
Fig. 2 is structural representation of the present invention;
In figure: 1 is three-jaw self-centering chuck, 2 is spring, and 3 is conical surface centring sleeve, and 4 is tartar axle, and 5 is workpiece, and 6 is rolling center.
Detailed description of the invention
One as shown in Figure 2 is not stopped centralizer, comprise three-jaw centering chuck 1, spring 2, conical surface centring sleeve 3, tartar axle 4, workpiece 5 and rolling center 6, described three-jaw self-centering chuck 1 is connected with tartar axle 4, described tartar axle 4 puts spring 2 and conical surface centring sleeve 3, and in the outer cover of conical surface centring sleeve 3 workpiece 5, hold out against with rolling center 6, described workpiece 4 comprises cylindrical hole and taper hole, described conical surface centring sleeve 3 positioning cylinder aperture, the taper hole face, tartar conical surface location of described tartar axle 4.The steel wire diameter of described spring is 1.5mm ~ 3mm.
Operation principle of the present invention is: before turning, tartar axle clamp in scroll chuck, uses amesdial centering, makes its jerk value be no more than 0.05mm.Then put spring and conical surface centring sleeve, load onto workpiece and just can car cylindrical as shown in Figure 1 with top holding out against.After car is complete, top retrogressing, conical surface centring sleeve and workpiece are released by spring, just can carry out the clamping turning of next workpiece after taking down workpiece.
Claims (2)
1. the centralizer that do not stop, comprise three-jaw centering chuck, spring, conical surface centring sleeve, tartar axle, workpiece and rolling center, it is characterized in that, described three-jaw self-centering chuck is connected with tartar axle, described tartar axle puts spring and conical surface centring sleeve, and in the outer cover of the conical surface centring sleeve workpiece, hold out against with rolling center, described workpiece comprises cylindrical hole and taper hole, described conical surface centring sleeve positioning cylinder aperture, the taper hole face, tartar conical surface location of described tartar axle.
2. one according to claim 1 is not stopped centralizer, and it is characterized in that, the steel wire diameter of described spring is 1.5mm ~ 3mm.
