The T-type sliding block of cooperation, adjusting screw rod in the T-type sliding slot and across the T-type sliding block and with T-type sliding block screw-thread fit and
Form leadscrew-nut mechanism；The T-type sliding block includes positioned at the rectangular block part of T-type sliding slot slot bottom and perpendicular to rectangular block part
And the column part of T-type sliding slot is stretched out, the connecting shaft that the column part is clamped by the scroll chuck of lathe；In the T-type
The opening both sides of sliding slot are respectively equipped with one of strip-shaped hole, and the strip-shaped hole is mutually parallel with T-type sliding slot；It is all provided in each strip-shaped hole
There are studs, one end of the studs to be screwed into the rectangular block part, the other end of studs after strip-shaped hole
It is screwed with nut；
The wherein one side edge of the connecting plate is equipped with the graduation mark that a row indicate length, and the graduation mark hangs down with strip-shaped hole
Directly, the axis of the extended line and the chuck of the zero graduation line in graduation mark intersects vertically；Also connect on the side wall of the connecting shaft
It is connected to the arrow of face graduation mark, the arrow is perpendicular to the symmetry axis of strip-shaped hole and arrow and the connection
The axis of axis intersects vertically.
Further, the arrow is arranged in a framework, and the framework is by one sector in steel bar besieged city, the frame
Body is fixed in the connecting shaft, and the plane where framework is vertical with connecting shaft, and arrow is located on the axis of symmetry of framework
And it is fixed on the external arc edge of framework.
Further, the chuck is scroll chuck.
Further, the connecting plate is split structure, is made of cover board and pedestal, the strip-shaped hole and T-type sliding slot
Opening portion setting on the cover board, the trench bottom of the T-type sliding slot point is set on the base, by twisting between cover board and pedestal
Enter the bolt on four corners of cover board to connect to form the complete strip-shaped hole and T-type sliding slot.
Beneficial effects of the present invention：Using two turning fixture for crankshaft provided by the invention come clamping bent axle, in use, first
The end of bent axle is clamped with the chuck of this fixture, screw rod is then turned and adjusts the movement of T-type sliding block, when the finger of T-type sliding block connection
When showing that the numerical value of the graduation mark indicated by arrow is equal to the distance value of the axis runout bent axle integral center-axis line of upper inclined connecting rod neck,
The axis coaxle of connecting shaft and the connecting rod neck for needing to process, at this point, the nut on studs is tightened fixed connection shaft (T-type
Sliding block) position after, by connecting shaft clamping on the scroll chuck of lathe itself, so that lathe spindle and connecting shaft, waiting for
The connecting rod neck three of processing is coaxial, to carry out turnery processing to connecting rod neck to be processed.Similarly, adjustable screw makes connecting shaft
With the connecting rod neck of below-center offset or the whole axis coaxle of bent axle, with realize to other biasing connecting rod necks turnery processing；By
This is as it can be seen that the present invention can adjust the position of connecting shaft by leadscrew-nut mechanism, to realize to different biasing sizes
The processing of connecting rod neck, to adapt to the processing of the bent axle of plurality of specifications size, adaptability is extremely strong, be particularly suitable for the rough turn of bent axle or
Person roughly grinds.
