Further, the thickness of the distance block is smaller than that of the ear of the rear thrust bearing.

Further, a pin for preventing the upper clamping plate from falling off is arranged at the top of the pin shaft.

Further, the pin shaft is sleeved with a spring, and two ends of the spring are abutted against the lower clamping plate and the upper clamping plate.

Further, a protection ring is arranged on the upper surface of the upper clamping plate at the position of the through hole, and the inner diameter of the protection ring is equal to the diameter of the through hole.

The beneficial effects of the utility model are as follows: the utility model provides a drilling positioning fixture of back thrust bearing, its is including being fixed in the bottom plate of drilling machine workstation, the bottom plate is provided with the lower plate through two risers, the centre of lower plate is fixed with the distance piece, the top of distance piece is provided with the punch holder, just the punch holder with be fixed in the round pin axle sliding connection at lower plate both ends, the distance piece is fixed with the screw rod, just the screw rod passes the punch holder, screw rod threaded connection has the handle the nut of punch holder down, the lower plate the both ends of punch holder all are provided with the through-hole that runs through both, one side of lower plate just corresponds the position fixing of through-hole has the mounting panel, mounting panel threaded connection has adjusting screw. The utility model has convenient operation, does not need workers to reposition drilling positions after clamping the workpiece, and can directly drill holes from the through holes, thereby being efficient and labor-saving.

Detailed Description

The utility model will now be described in further detail with reference to the drawings and the specific embodiments, without limiting the scope of the utility model.

As shown in fig. 2, a drilling positioning fixture for a rear thrust bearing of the present embodiment includes a bottom plate 1 fixed on a drilling machine workbench, the bottom plate 1 is provided with a lower clamping plate 3 through two vertical plates 2, a distance block 4 is fixed in the middle of the lower clamping plate 3, an upper clamping plate 5 is provided above the distance block 4, the upper clamping plate 5 is slidably connected with a pin shaft 6 fixed on two ends of the lower clamping plate 3, a screw rod 7 is fixed on the distance block 4, the screw rod 7 penetrates through the upper clamping plate 5, a nut 8 for pressing the upper clamping plate 5 downwards is in threaded connection with the screw rod 7, through holes 9 penetrating through the lower clamping plate 3 and the upper clamping plate 5 are respectively provided at two ends of the lower clamping plate 3, a mounting plate 10 is fixed at one side of the lower clamping plate 3 and corresponding to the positions of the through holes 9, and the mounting plate 10 is in threaded connection with an adjusting screw 11.

The utility model is specially used for the drilling clamp of the ear part of the rear thrust bearing, when in operation, the length of the adjusting screw 11 is adjusted firstly, so as to determine the quantity of the ear part of the rear thrust bearing inserted between the lower clamping plate 3 and the upper clamping plate 5, the distance block 4 is clamped between the two ear parts of the rear thrust bearing, so as to position a workpiece, and then the nut 8 is screwed, so that the ear part of the rear thrust bearing is clamped between the lower clamping plate 3 and the upper clamping plate 5. The lower clamp plate 3 both ends of upper clamp plate 5 all are provided with through-hole 9, and set up in lower clamp plate 3 upper clamp plate 5 through-hole 9 aligns, and during drilling, promote radial drill's aircraft nose, make the drill bit pass be located upper clamp plate 5 through-hole 9 to the location drilling position.

In order to prevent the upper clamping plate 5 from falling off, the top of the pin shaft 6 is provided with a pin 12; the pin shaft 6 is sleeved with a spring 13, and two ends of the spring 13 are abutted against the lower clamping plate 3 and the upper clamping plate 5, so that when the nut 8 is loosened, the upper clamping plate 5 is jacked up by the spring 13, and therefore workpieces can be placed conveniently.
