Detailed Description
The following detailed description of the preferred embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in fig. 1 and 2, the cross needle bearing outer groove distance measuring instrument comprises a base plate 1, 4 nylon universal adjusting feet 21 are installed below the base plate 1, a workbench 3 is arranged on the base plate 1, a left positioning plate 2 is arranged on the left side of the workbench 3 on the base plate 1 and used for positioning the left end of the cross needle bearing, a right loading plate 13 is arranged on the right side of the workbench 3 on the base plate 1 and connected with a cylinder 14 and used for loading 800N force on the cross bearing, and a pressure regulating filter 8 connected with the cylinder 14 and used for regulating the air inlet pressure of the cylinder is installed on the base plate 1. A precise guide rail 6 is arranged behind a workbench 3 on a bottom plate 1, a connecting plate 7 is arranged on the precise guide rail 6, a shifting lever 5 is connected to the left side of the precise guide rail 6, and the shifting lever 5 drives the precise guide rail 6 to slide back and forth. The front side and the rear side of the shifting lever 5 on the bottom plate 1 are provided with limit blocks 4, and the limit blocks 4 on the two sides of the shifting lever 5 limit the front-rear sliding stroke of the precision guide rail 6, namely the position of the cross needle bearing during measurement and withdrawal. The measuring mechanism of the cross bearing is arranged on the connecting plate 7 and comprises a fixing plate 9 connected with the connecting plate 7, spring strips 11 are connected to the left side and the right side of the fixing plate 9 respectively, the other ends of the two spring strips 11 are connected with a left floating block 18 and a right floating block 16 respectively, the left floating block 18 is connected with a dial indicator 20 through a gauge stand 19, the right floating block 16 is connected with an adjusting screw 12 and a measuring rod 15, a tension spring 17 is connected between the front ends of the left floating block 18 and the right floating block 16, a measuring point 22 special for a groove is arranged at the lower end of the left floating block 18 and the lower end of the right floating block 16 respectively, and bearing positioning blocks 10 are arranged on the left side and the right side of the connecting plate 7 on the workbench 3 and used for measuring after the cross needle bearing is positioned.
When the device is used, a standard part is firstly placed on a workbench 3 and leans against a cross bearing positioning plate 10 and a left positioning plate 2, then an air source is connected, a pressure regulating filter 8 is adjusted to enable an air cylinder 14 to reach corresponding air pressure of required loading force, the air cylinder 14 pushes a right loading plate 13 to press the standard part tightly, then a precision guide rail 6 is pushed to slide towards the workbench 3, two measuring points 22 at the lower ends of a left floating block 18 and a right floating block 16 are placed on the outer groove wall of the cross bearing and are consistent in height (a proper gap is reserved at the groove bottom), the position of a limiting plate 4 is adjusted, finally the spring force of a spring piece 11 and a tension spring 17 is adjusted according to the variation of a dial indicator 20 to enable the two measuring points 22 to abut against the inner side of the groove (the size is determined according to the size of the bearing groove), the dial indicator 20 is adjusted to be at zero position after stabilization, and the calibration is completed.
