Detailed Description

As shown in fig. 1, the externally splined gear is a radially outwardly projecting portion of the propeller shaft body having a common axial centerline with the propeller shaft body. Three radial holes in the tooth grooves are required to be drilled on the spline gear at equal arc length or equal angle. It is assumed that the alignment (finding the correct three radial hole punched tooth slots in the spline gear) conditions are that the number of teeth in the spline gear is an integer multiple of 3.

The utility model discloses a after having beaten first radial hole 11 in a tooth's socket on the spline gear, can find the second tooth's socket 12 and the third tooth's socket that punches fast.

The invention is further described below with reference to the following examples and figures:

example one

As shown in figure 1, the alignment device of the V-shaped positioning table clamp for radial drilling of the external spline gear comprises two groove plates 31 which are symmetrically arranged and provided with V-shaped grooves 3, a gear groove 32 is formed between the two groove plates, and an observation hole capable of observing a spline gear tooth groove in the gear groove 32 is formed in the front half groove plate of one groove plate 31.

The observation holes are one or more circular holes 4, and each circular hole 4 can only observe one tooth socket on the spline gear in the gear groove 32.

The arrangement is that after the drill bit is used for drilling the first radial hole 11 on the spline gear 1, the drilling tooth grooves of the second drilling tooth groove 12 and the third radial hole are found as soon as possible. The principle is as follows: firstly, a tooth groove right below the drill bit 2 is determined as a punching tooth groove of a first radial hole 11, then the positions of the other two tooth grooves are determined by measuring equal arc length or by counting the number of teeth, the position of the tooth groove positioned in front is used as the position for searching a second punching tooth groove 12, and then a round hole 4 which can only observe the tooth groove is punched on the front half groove plate of one groove plate 31. Thus, when the first radial hole 11 has been drilled with its drilling tooth slot, the spline gear 1 is rotated and viewed through the circular hole 4, and when the tooth slot with the opening of the first radial hole 11 is viewed right, the second drilling tooth slot 12 is already located right below the drill bit 2. According to the method, the punching tooth slot of the third radial hole can be quickly found.

The V-shaped positioning table clamp can be used for processing spline gears with different diameters, the positions of observation holes of the V-shaped positioning table clamp are correspondingly provided with a plurality of positions, and therefore the corresponding number of round holes 4 are required to be arranged.

Example two

As shown in FIG. 2, the aligning device of the V-shaped positioning table clamp for radial drilling of the external spline gear is different from the first embodiment in that: the viewing aperture is an elongated slot 5 which enables at least one tooth groove on the spline gear 1 in the gear groove 32 to be viewed, and one or more indicia 6 are provided on the slot 5, each indicia 6 being specifically directed to only one tooth groove on the spline gear. This is arranged to identify the second perforation slot 12 by marking the slot 6 pointing towards the mouth of the first radial hole 11. The advantage is that the mark which needs to be added to the spline gear 1 with different diameters can be added.

EXAMPLE III

3-5, an alignment device of a V-shaped positioning table clamp for radial drilling of an external spline gear is different from the first embodiment in that: the observation hole is a long and narrow sliding notch 5, a peeping tube 8 capable of sliding along the sliding notch 5 is arranged on the sliding notch 5, and the peeping tube 8 is provided with a tube hole 81 capable of observing only one tooth groove on the spline gear 1 in the gear groove 32.

Further, one end of the sight tube 8, which is located in the gear groove 32, is provided with a flange 82, and the other end is provided with an external thread, and a fastening nut 83 is sleeved on the external thread. This enables fixing at any position on the sliding groove 5.

Further, the sliding notch 5 is located on one side of the gear groove 32 and is widened to form a rib groove 71 for filling the rib 82 to slide, and the depth of the rib groove 71 is greater than the thickness of the rib 82 of the sight tube 8. This is to avoid the rib 82 from being located in the gear groove 32, interfering with the rotation, etc., and the entrance and exit of the spline gear 1.

The advantage of this embodiment is that it can be used for the alignment of the drilling position of spline gear 1 with any diameter.
