[0026] A drill-free device for drilling the end face of a thin-walled sleeve includes a base 1, a worktable 2, a bracket 6, a pressure plate 8, a part positioning mandrel 14, and a handle 13. The pressure plate 8 is connected to the upper end of the bracket 6, and the lower end of the bracket 6 is connected to the worktable 2. A clamping block 11 is installed on the pressure plate 8. The lower end of the part positioning mandrel 14 is connected to the worktable 2, and the upper end is located below the clamping block 11. The lower part of the handle 13 is connected to the worktable 2, and the handle is located below the end of the pressure plate 8 away from the bracket 6.

[0027] The base 1 of this utility model is equivalent to a general equipment base and is used to fix it to the workbench of a vertical bench drill.

[0028] 1. With the arrangement of the worktable 2, support 6, clamping block 11, part positioning mandrel 14, and handle 13, during processing, the thin-walled sleeve is fitted over the part positioning mandrel 14, which positions the sleeve. The part is then clamped by the pressure plate 8 and handle 13. Since the clamping block 11 is in contact with the part, damage to the part during clamping is reduced. For drilling, a vertical bench drill is used. No special drilling template is required, and only personnel with a drilling machine operator's license can operate the machine. Operation is simple, processing time is short, and labor and equipment costs are low.

[0029] In one or more embodiments of this utility model, the bracket 6 is fixed to the workbench 2 by the bracket positioning screw 5.

[0030] In one or more embodiments of this utility model, to facilitate the handling of parts, a U-shaped groove is provided at the upper end of the bracket 6. The thin-walled sleeve end face drilling-free die device also includes a pressure plate positioning pin 7. The right end of the pressure plate 8 is located in the U-shaped groove, and the pressure plate positioning pin 7 passes through the front end of the pressure plate 8. Both ends of the pressure plate positioning pin 7 are connected to the groove wall of the U-shaped groove. Through the arrangement of the pressure plate positioning pin 7 and the U-shaped groove, the pressure plate 8 can move up and down around the pressure plate positioning pin 7. When the pressure plate 8 moves upward, parts can be taken out or put in; when the pressure plate 8 moves downward, parts can be pressed.

[0031] In one or more embodiments of this utility model, for more precise positioning, the thin-walled sleeve end face drilling without a drill mold device further includes a centering screw 9 and a centering screw locking nut 12. One end of the centering screw 9 is fixed to the pressure plate 8, and the other end is used to fix the clamping block 11 to the pressure plate 8 via the centering screw locking nut 12. The centering screw 9 allows for more precise positioning of the parts, preventing misalignment.

[0032] In one or more embodiments of this utility model, for more precise positioning, the thin-walled sleeve end face drilling without a drill jig device further includes a worktable positioning screw 3, a worktable positioning screw locking nut 4, and two reference pins 15. The worktable 2 is connected to the base 1 via the worktable positioning screw 3 and the worktable positioning screw locking nut 4. The two reference pins 15 are symmetrically distributed and installed on the base 1, with the worktable 2 located between the two reference pins 15. The projection of the centering screw 9 onto the worktable 2 and the two reference pins 15 are on the same diameter circle, ensuring that the centering screw 9 is located at the center of the line connecting the two reference pins 15. Before machining the part, the center hole at the top of the centering screw 9 is aligned with the center of the drill bit of the drilling machine. This action is to ensure that the center of the drill bit of the drilling machine and the two reference pins 15 are on the same diameter circle.

[0033] In one or more embodiments of this utility model, in order to facilitate pressing, the rear end of the pressure plate 8 is provided with a mating handle portion that mates with the handle portion of the handle 13, so as to facilitate symmetrical force application.

The pre-machined hole positioning screw 10 is mounted on the pressure plate 8, with its lower end extending out of the lower surface of the pressure plate 8. The pre-machined hole positioning screw 10 is used for angular positioning when the number of drilled holes is greater than 2 holes and when the angle between the center of the two holes and the center of the part is not 180°.

[0035] In this invention, during processing, the tip of the machining tool is aligned with the center hole on the top surface of the centering screw 9, so that the center of the drill bit of the drilling machine and the two reference pins 15 are on the same diameter circle.

[0036] In this utility model, the worktable 2 can rotate around the worktable positioning screw locking nut 4 to realize the processing of symmetrical holes on the left and right sides of the part; the pressure plate 8 can rotate around the pressure plate positioning pin 7 to realize the clamping and loosening of the part.

[0037] In this utility model, after the initial machining hole is completed, the part is rotated and the pre-machined hole positioning screw 10 is placed in the pre-machined hole of the part. At this time, the projection of the centering screw 9 on the worktable 2 and the two reference pins 15 are on the same diameter circle, and the new hole of the part is machined. The pre-machined hole positioning screw 10 is used for angular positioning when the number of drilled holes is greater than 2 holes and when the angle between the center of the two holes and the center of the part is not 180°.

[0038] Reference pins 15 are symmetrically distributed on the left and right sides of the worktable to control the hole spacing.

[0039] In this utility model, the positioning mandrel 14, clamping block 11, reference pin 15, and positioning screw 10 of the pre-machined hole of the part can be replaced according to one's own needs to process thin-walled sleeve parts of different specifications.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
