Description

This invention relates to a measurement technique. Known automatic measuring machines, containing a power drive, a periodic conveyor, measuring and locking positions and sorting device. These machines require a significant number of locking positions, in particular, to protect measuring positions from control objects with an excessive allowance, from incorrectly oriented objects, and the like. and therefore complex in construction and have increased dimensions. Also known is an automatic measuring machine containing a power actuator, a batch conveyor, a locking and measuring positions, including axially movable base tables with the last movement limiters, coaxial gauges and a plug, a gauge for entering calibers, a gauge for the bottom of the object being monitored, as well as a sorting device. This machine allows to combine blocking positions of the value of the allowance and incorrect orientation, but does not allow partial alignment with the measuring positions, which also complicates the design and increases the dimensions of the machines. The purpose of the invention is to simplify the design and reduce the size. The goal is achieved by the fact that the blocking position is aligned with the measuring position of the bottom thickness, the gauge entry meter is made in the form of a bottom bottom gauge, and the base table is made with a diameter smaller than the diameter of the plug gauge and is provided with an annular protrusion. FIG. 1 given the proposed machine, a section along the axis of the camshaft of the machine in FIG. 2 - the same, the position of the blockage and measurement of the bottom surface at the normal position of the cardan ring, section; in fig. 3 - the same, when turned upside down. The control and measurement machine contains a frame 1, a power drive 2, a camshaft 3 with cyclic cam 4, a conveyor 5 of periodic operation and measuring positions 6 (one blocking position and measuring of the bottom bottom are shown). Kszcca position is equipped with a lift

7, carrying a spring-loaded base table moving in the axial direction of singing

8, connected to the elevator with conical mating 9. The position of the blocking and measuring the bottom thickness also contains coaxially arranged gauges - the ring 10 and the stopper 11, the bottom thickness gauge 12, made, for example, in the form of a pneumatic heater, as well as a spring-loaded clamp 13 of the tested ring to base table. The base table is provided with axial movement limiters 14 and an annular protrusion 15, the outer diameter of which is smaller than the diameter of the plug gauge, the inner one exceeds the minimum diameter of the piston gage, and the height of the annular part is the depth of the fillets.

The machine also contains a sorting mechanism 16 controlled by signals from measuring position meters.

Testing machine for rings of cardan bearings works as follows.

The controlled rings from the magazine enter the periodic conveyor 5 and from there to the measuring positions. Lift 7 captures the ring with a spring-loaded base table 8 and lifts the stops 14 to the end of the measuring position up to the stop (see Fig. 2). At the same time, the object being monitored passes inside the caliber ring 10 and is put on the caliber plug 11. The object being monitored is pressed against the base table. a spring-loaded clamp 13. The meter 12 controls the thickness h of the bottom of the ring of the cardan bearing and, via a pneumatic electro-contact converter (not shown), controls the operation of the mechanism 16 for sorting, rejecting the ring with an increased and lowered bottom thickness.

When a ring with an oversized outer diameter or a lower inner diameter is hit, the monitored ring does not fit into the caliber ring (does not fit over the caliber plug), the base table does not reach the spring 14 and the limiter 14 is spring-loaded — the ring is rejected as having a reduced bottom thickness. In this case, the gauge of the thickness of the bottom of the ring serves as a gauge for the occurrence of bumps.

When an inverted ring hits (see Fig. 3), the annular protrusion 15 of the base table enters the fillet at the bottom of the ring of the cardan bearing, which leads to measuring the thickness h of the bottom of the bearing along the fillet and discarding the latter in thickness of the bottom,

as h. h.
