Abstract
An eccentric sphere machining tool comprises a disc-shaped tool main body, wherein one end of a transverse shaft is integrally connected to the end face of the tool main body, a key groove is formed in the side wall of the transverse shaft, the central line of the transverse shaft deviates from the central line of the end face of the tool main body in parallel, a spherical workpiece to be machined can be sleeved and fixed on the transverse shaft, and the central line of the end face is the spherical central line of the spherical workpiece; the other end of the cross shaft is detachably connected with a gland through a fastener, the shape and specification of the gland are the same as those of the tool main body, and the relative connection position of the cross shaft and the end face of the gland is also symmetrical to that of the tool main body at the other end. The utility model discloses a rational in infrastructure, treat that the spheroid work piece position of processing easily adjusts, fixed reliable, adaptability is wide, satisfies the requirement of various processing technology such as car, grinding, boring. The center is easy to align when the secondary repeated machining is carried out, the eccentric machining precision of the ball is high, and the machining efficiency is greatly improved.
Description
The technical field is as follows: the utility model relates to a processing construction installation equipment of valve eccentric sphere.
Background art: the eccentric ball is a common ball valve component, and a tool clamp is generally used in the machining process due to the deviation of the working rotation center line of the eccentric ball and the center line of the ball. The existing eccentric sphere machining tool is not ideal in design, is generally difficult to match various procedures such as turning, grinding and boring, is difficult to align when in secondary repeated machining, and is low in machining efficiency.
The invention content is as follows: the utility model provides a to prior art not enough, the utility model provides an eccentric spheroid processing frock rational in infrastructure.
The utility model comprises a disc-shaped tool main body, one end of a cross shaft is integrally connected with the end surface of the tool main body, the side wall of the cross shaft is provided with a key slot, and the center line of the cross shaft deviates from the center line of the end surface of the tool main body in parallel, a spherical workpiece to be processed can be sleeved and fixed on the cross shaft, and the center line of the end surface is the spherical center line of the spherical workpiece; the other end of the cross shaft is detachably connected with a gland through a fastener, the shape and specification of the gland are the same as those of the tool main body, and the relative connection position of the cross shaft and the end face of the gland is also symmetrical to that of the tool main body at the other end.
The utility model discloses a rational in infrastructure, treat that the spheroid work piece position of processing easily adjusts, fixed reliable, adaptability is wide, satisfies the requirement of various processing technology such as car, grinding, boring. The center is easy to align when the secondary repeated machining is carried out, the eccentric machining precision of the ball is high, and the machining efficiency is greatly improved.
The invention is further described with reference to the following figures and examples.
Description of the drawings: fig. 1 is a schematic diagram of the main structure of the embodiment.
Fig. 2 is a right side view of the tool body of fig. 1 along with a transverse axis.
Figure 3 is a left side view of the gland of figure 1.
FIG. 4 is a schematic view of the working clamping state of the embodiment.
The specific implementation mode is as follows: as shown in fig. 1 to 4, the tool body 1 is disc-shaped, one end of a transverse shaft 2 is integrally connected to an end face of the tool body 1, a key groove 3 is provided on a side wall of the transverse shaft 2, and a transverse shaft center line 4 is offset in parallel from an end face center line 5 of the tool body 1. The spherical workpiece 9 to be processed can be sleeved and fixed on the transverse shaft 2, and the end surface central line 5 is the spherical central line of the spherical workpiece 9. The other end of the cross shaft 2 is detachably connected with a gland 7 through a fastener 6, the shape and the specification of the gland 7 are the same as those of the tool body 1, and the relative connecting position of the end faces of the cross shaft 2 and the gland 7 is also symmetrical to that of the tool body 1 at the other end.
In the embodiment, the end of the cross shaft 2 connected with the gland 7 is in a track shape, and the end face of the gland 7 is correspondingly provided with a track-shaped counter bore 8 to form a connecting and positioning structure. The connection between the end of the transverse shaft 2 and the gland 7 is thus positioned more quickly and the relative position is accurate. The fastener 6 can generally adopt an inner hexagon bolt, the center of the end part of the transverse shaft 2 can be provided with a screw hole 10, a through hole 11 is arranged at the counter bore 8 of the gland 7, the inner hexagon bolt can be screwed into the screw hole 10 by crossing the through hole 11, the assembly and the disassembly are convenient, and the connection is stable. The key groove 3 of the embodiment is crescent, and a crescent key can be adopted when the key groove is fixedly matched with the spherical workpiece 9, so that the stability is good, and the adjustment is convenient.
In actual clamping, as shown in fig. 4, the spherical workpiece 9 to be machined is sleeved and fixed on the horizontal shaft 2, and a plurality of adjusting pads 12 are further sleeved on the horizontal shaft 2 for more conveniently adjusting and fixing the horizontal position of the spherical workpiece 9. In a clamping state, the end surface central line 5 of the tool main body 1 is the spherical surface central line of the spherical workpiece 9, and the transverse axis central line 4 is superposed with the working rotation central line of the spherical workpiece 9, namely the valve rod connecting central line of the sphere is superposed after completion.
