In an embodiment of the present invention, as shown in fig. 1 and 2, the compressor crankshaft positioning device further includes: a fourth chute 29, a center seat 30, a fourth slider and a third lead screw 31; the fourth chute 29 is provided on the bottom plate 10; the tip seat 30 is placed on the bottom plate 10, and the tip seat 30 is located on the fourth sliding groove 29; a fourth threaded hole is formed in the fourth sliding block, the fourth sliding block is embedded into the fourth sliding groove 29, and the fourth sliding block is connected with the bottom of the center seat 30; the third lead screw 31 is embedded in the fourth sliding chute 29, the third lead screw 31 passes through the fourth sliding block, one end of the third lead screw 31 passes through the bottom plate 10, and the other end of the third lead screw 31 is rotatably connected with the bottom plate 10.
The fourth sliding chute 29 is arranged on the bottom plate 10, the fourth sliding block is embedded into the fourth sliding chute 29, and the fourth sliding block is connected with the bottom of the center seat 30, so that the center seat 30 moves in the fourth sliding chute 29 through the fourth sliding block; through in imbedding third lead screw 31 fourth spout 29, pass the fourth slider with third lead screw 31, wear out bottom plate 10 with the one end of third lead screw 31 to make the other end of third lead screw 31 rotate with bottom plate 10 and be connected, in order to realize that bottom plate 10 supports third lead screw 31, can also realize simultaneously, rotate third lead screw 31, make third lead screw 31 drive fourth slider and the removal of apical grafting seat 30. Adopt above-mentioned structure, rotate third lead screw 31, make third lead screw 31 drive fourth slider and apical seat 30 remove to the bent axle direction to the realization makes apical seat 30 laminate mutually with the tip of bent axle, and then realizes carrying out the top tightly through apical seat 30 to the one end that deviates from drilling when the tip to the bent axle is drilled man-hour, takes place the displacement in order to avoid the bent axle, with the machining precision who promotes the bent axle.
In an embodiment of the present invention, as shown in fig. 1 and fig. 2, the compressor crankshaft positioning device further includes: a third hand wheel 32; the third hand wheel 32 is sleeved on the outer side of one end of the third lead screw 31, and the third hand wheel 32 is located on the outer side of the bottom plate 10.
The third hand wheel 32 is sleeved on the outer side of one end of the third lead screw 31, and the third hand wheel 32 is located on the outer side of the bottom plate 10, so that the third lead screw 31 is driven to rotate through the third hand wheel 32, the difficulty in rotating the third lead screw 31 is reduced, and the use experience of products is improved.
