Utility model content
The technical problem to be solved by the present invention is to provide a kind of grindings conveniently, reduce hand labor, work efficiency is high
Transmission shaft ball-and-socket grinding tool.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of transmission shaft ball-and-socket grinding tool, wound
New point is: including
One swingle, the swingle is stepped, including the first rotation section, the second the rotation section, third being sequentially distributed
Section and the 4th rotation section are rotated, wherein the first rotation section, the second rotation section and the 4th rotation section are cylindrical, and the second rotation
Section, the first rotation section, the 4th rotation section bore be gradually reduced, it is in a circular table shape that third rotates section, big one end of bore and the
Two rotation sections are connected, and all have an external screw thread knot far from the side of third rotation section in the first rotation section and the 4th rotation section
Structure；
One grinding bulb, the grinding bulb includes a bulb main body, and the bulb main body is in a circular table shape, and its side wall is in arc
Shape holds the through-hole that the 4th rotation section protrudes into one in bulb main body, also has spiral shell in one on the inner wall of bulb main body
Line structure, and fixation is connected through a screw thread between the 4th rotation section.
Further, also there is a retaining mechanism, the retaining mechanism between the bulb main body and the 4th rotation section are as follows:
It is connected between bulb main body and the 4th rotation section by a clamping screw, while in bulb main body there is an appearance clamping screw to wear
The through-hole crossed, the tapped blind hole for protruding into and being threadedly engaged with an appearance clamping screw in the 4th rotation section.
Utility model has the advantages that in the present invention, using the grinding tool, passing through swingle and mill ball
The combination of head, it is very convenient so as to cooperate driving mechanism to realize to the automatic grinding of transmission shaft ball-and-socket, it decreases
Hand labor also improves working efficiency accordingly, and uses side wall for the round table-like design of arc grinding bulb,
It is to be able to more preferably match with the ball-and-socket of transmission shaft, is more convenient grinding.
For retaining mechanism is arranged between bulb main body and the 4th rotation section, thus in bulb main body and the 4th rotation section spiral shell
It is fixed again using clamping screw after line connection, the two is avoided to occur relatively rotating and influencing whole processing.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the side view of transmission shaft in the utility model.
Fig. 2 is the cross-sectional view of transmission shaft in the utility model.
Fig. 3 is the schematic diagram of the transmission shaft ball-and-socket grinding tool of the utility model.
Specific embodiment
The following examples can make professional and technical personnel that the utility model be more fully understood, but therefore will not
