A kind of motor rear end covers the radially processing tool of wire hole; It is characterized in that: comprise that base plate, the gripper shoe, the end that vertically are packed on the base plate are supported on the mandrel that is used to install rear end cap on the gripper shoe; Be located at the pressing plate and the clamp nut of the mandrel other end; Be packed in gripper shoe upper end and the bushing plate parallel and be packed in the drill bushing on the bushing plate with base plate; Said drill bushing be located at mandrel directly over, the distance to wire hole center radially is consistent to the bottom of the distance of gripper shoe medial surface and rear end cap at said drill bushing center; Also be provided with on the said gripper shoe with rear end cap on the corresponding through hole in axial location hole, said locating hole is connected through bearing pin with through hole.

The technical scheme that the utility model can also be taked is:

Be fixed with the spacer that is complementary with the rear end cap centre bore on the said mandrel.

Said gripper shoe upper center is shaped on the groove consistent with the bushing plate width, and said bushing plate is inlaid in the groove.

In the said through hole axle sleeve is installed.

Advantage and the good effect that the utlity model has are:

Through adopting above-mentioned frock; Can make things convenient for securely rear end cap is fixed on the Drilling machines bench top, make the radially wire hole position of drill bit workpiece, drill bushing guarantees that drill bit can accurately locate adding man-hour; Play the effect of leading and preventing the drill bit sideslip; And then guarantee dimensional accuracy and the positional precision that wire hole is processed, and improved production efficiency, satisfy the requirement of mass production.

The specific embodiment

For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:

See also Fig. 1-3; A kind of motor rear end covers the radially processing tool of wire hole; Comprise that base plate 1, the gripper shoe 2, the end that vertically are packed on the base plate are supported on the mandrel 3 that is used to install rear end cap on the gripper shoe; Be located at the pressing plate 4 and clamp nut 5 of the other end on the mandrel; Be packed in gripper shoe upper end and the bushing plate 6 parallel and be packed in the drill bushing 7 on the bushing plate with base plate, said drill bushing be located at mandrel directly over, the distance to wire hole center radially is consistent to the bottom of the distance of gripper shoe medial surface and rear end cap at said drill bushing center; Also be provided with on the said gripper shoe with rear end cap on the corresponding through hole in axial location hole, said locating hole is connected through bearing pin 8 with through hole.Concrete; Above-mentioned mandrel comprises the main part 3-1 that is located at the middle part; Be located at the locating shaft part 3-2 of left end and be located at the screw-threaded coupling part 3-3 of right-hand member; Wherein main part cooperates with the centre bore of rear end cap, and locating shaft partly is inserted in the center positioning hole of gripper shoe, and screw-threaded coupling partly is used for connecting pressing plate and clamp nut.Rear end cap is sleeved on the mandrel main part; Through hole on locating hole and the gripper shoe is aligned to lock; Through adjusting clamp nut to the gripper shoe direction; Can rear end cap be pressed on the medial surface 2-1 of gripper shoe, at this moment, be installed in the position of the drill bushing aligning radially wire hole to be processed on the bushing plate.

Above-mentioned rear end cap can directly be sleeved on the mandrel main part, and promptly the diameter of mandrel main part is consistent with the rear end cap center-hole diameter.For being applicable to the processing of different size rear end cap, lower production cost, avoid rear end cap wearing and tearing to the mandrel main part in cargo handling process; Prolong its service life; Can make mandrel main part diameter less than the rear end center-hole diameter, on the mandrel main part, further fixedly mount the spacer 9 that is complementary with the rear end cap centre bore, concrete; At spacer screwed hole 10 is set radially; On the mandrel main part, be provided with and the corresponding annular recess 11 of screwed hole,, spacer be fixed on the mandrel through being installed in the screw 12 in screwed hole and the annular recess.
