Description
Technical Field
The utility model relates to a lathe processing field, a processingequipment of bent axle crank pin axle journal specifically says so.
Background
The surface processing of the crank pin journal of the crankshaft requires that the crankshaft is clamped on a clamp of a machine tool and is firstly processed by turning. Then other processing modes are carried out for processing. Each crank pin journal of the crankshaft has an angle therebetween, which is a phase angle of the crank pin journal. The phase angle of the crank pin needs to be ensured during crankshaft machining. The crank pin journal turning is to clamp the crankshaft on a lathe, and after one crank pin journal is machined, the crankshaft is rotated on the lathe by a certain angle (the phase angle of the crank pin) to machine the next crank pin journal. In the past, when machining crank pin journals on a lathe, a crankshaft needs to be checked on a platform, actual angles of the crank pin journals are detected, and differences between the actual angles and theoretical indexing are calculated. And then, the crankshaft is rotationally adjusted according to the calculated numerical value when the shaft diameter of each crank pin is processed so as to ensure the phase angle of the journal of the crank pin. Although this ensures indexing of the crankpin journal, it is problematic. The first is that the adjustment is inconvenient and the labor intensity of the operator is high. Secondly, the requirement on the adjusting skill of the crankshaft phase angle of the operator is high. Thirdly, the adjustment time is long, the efficiency is low, and the error is large and inaccurate.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a quick phase place angle positioning device of bent axle crank pin axle journal.
The specific technical scheme is as follows:
the utility model provides a quick phase place angle positioning device of bent axle crank pin axle journal, includes the lathe, and the lathe passes through threaded connection's mode and is connected with the screw hole of bolt seat, and the one end of square head bolt is pegged graft in the bolt seat, and the other end and positioning seat spiro union, the upper end of positioning seat still is equipped with the locating piece, the locating piece passes through the mode of screw and is in the same place with positioning seat fixed connection, the working plane and the crank pin footpath butt of locating piece, the size of locating piece matches the setting mutually with the crank pin footpath size of difference.
The positioning seat is perpendicular to the plug seat.
The square-head bolt is in clearance fit with the inside of the bolt seat.
The utility model has the advantages that: the locating direction of bent axle crank pin axle journal is mutually perpendicular with the activity direction of square head bolt, does not influence bent axle crank pin axle journal's positioning accuracy under the mode of inserting is pulled out for the activity to square head bolt and bolt seat, can realize quick location to the size of the different bent axle crank pin axle journals of adaptation.

Detailed Description
The following description specifically explains the utility model discloses, as shown in fig. 1, fig. 2, fig. 3, fig. 4, a quick phase place angle positioning device of crankshaft crank pin axle journal, the lathe passes through threaded connection's mode and is connected with the screw hole of bolt seat 1, and the one end of square head bolt 2 is pegged graft in bolt seat 1, the other end and 3 spiro unions of positioning seat, the upper end of positioning seat 3 still is equipped with locating piece 4, locating piece 4 is in the same place through the mode of screw and 3 fixed connection of positioning seat, the working plane 401 and the 5 butts in crank pin axle footpath of locating piece 4, the size of locating piece 4 and 5 sizes in the crank pin axle footpath of difference match the setting mutually.
The positioning seat 3 is perpendicular to the bolt seat 1.
The square-head bolt is in clearance fit with the inside of the bolt seat.
The utility model discloses a theory of operation is: the bolt seat 1 is connected to a clamp of a machine tool in a threaded connection mode. The square head bolt 2 is in threaded connection with the positioning seat 3, and the positioning block 4 is connected to the positioning seat 3 in a threaded connection mode and then connected. Put the bent axle on the anchor clamps of lathe, insert square head bolt 2 in bolt seat 1, then rotate the bent axle, use the crank pin axle journal that corresponds with 3 sizes of positioning seat to lean on tight locating piece 4, confirm to lean on tightly the back, press from both sides the anchor clamps at bent axle both ends tightly, fix the bent axle. Then the positioning device in the bolt seat 1 is pulled out, and the corresponding crank pin shaft diameter is processed. After the processing is finished, the positioning devices with different sizes of the positioning seats 3 are inserted into the bolt seats 1, the crankshafts rotate, the corresponding crank pin shaft diameters are close to the positioning blocks 4, then the positioning devices are pulled out, and the corresponding crank pin shaft diameters are processed.
Claims (3)
