The utility model discloses a flat-bottom spindle oil level measurer which comprises a connecting plate, a measuring column is fixedly connected to the bottom of the connecting plate, two arc-shaped clamping blocks are connected to the bottom of the connecting plate in a sliding mode, a clamping assembly is arranged at the bottom of the connecting plate, and the clamping assembly is used for driving the two arc-shaped clamping blocks to move. The oil level in the oil groove of the flat-bottom spindle is measured for the first time through the measuring column, the locking structure is released after measurement is completed, fixation of the limiting block is removed, then the floater is driven to move through buoyancy of lubricating oil in the oil groove, and therefore the measuring scale is pushed to slide between the measuring channel and the inner wall of the through groove; the top end of the measuring scale extends to the top of the connecting plate, oil level information can be read by observing the scale marks on the scale, secondary measurement is completed, finally, the measuring column is pulled out, the oil stain position on the measuring column is observed, oil level information of primary measurement is obtained, and then two-time measurement data are compared, so that the measurement accuracy is improved. Therefore, the accuracy and the reliability of oil level measurement are effectively improved.

The utility model relates to a clamp for a piston without draft angle on the side wall of an inner cavity in the field of manufacturing of aluminum pistons of internal combustion engines, according to the characteristic that the side wall of the inner cavity of the piston has no draft angle, the circular arc in the circumferential direction of a positioning surface of the clamp is the same as the corresponding position of the piston, and the inner side wall of the piston 20 is tensioned by utilizing the radial expansion of an expansion claw of the clamp; the circumferential shape and size of the clamp positioning point are the same as those of the side wall of the piston inner cavity, so that the positioning precision of the piston inner cavity is high; the expansion claws are high in expansion and contraction motion precision and are in symmetrical motion, under the condition that the actual size change of the side wall of the inner cavity of the piston blank is large, the positioning precision of the clamp is guaranteed, and the wall thickness difference of the inner cavity of the piston is accurately controlled; the clamp is provided with three pairs of expansion claws, expansion of the first pair of expansion claws at the front end of the clamp is driven by a machine tool spindle oil cylinder, the other two pairs of expansion claws are driven by springs in the clamp to generate expansion actions, and retraction actions are driven by the oil cylinder. The three pairs of tensioning claws synchronously act to tension the inner side wall of the piston 20, and the stroke of the tensioning claws is adjustable.
