DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6The utility model provides a technical solution: a slotting positioning mechanism for drill processing, including a slotting positioning mechanism body 1 and a workpiece 9, a slotting positioning plate 8 is also provided on the slotting positioning mechanism body 1, and a through hole with the same shape as the hole slot required by the workpiece 9 is opened on the slotting positioning plate 8, and the slotting positioning plate 8 is placed on the workpiece 9. This structure can perform slotting positioning processing on the workpiece 9 through the slotting positioning plate 8, so that the slotting drill 11 slots the workpiece 9 at the through hole of the slotting positioning plate 8. At the same time, when slotting is performed on the plane of the workpiece 9, the slotting positioning plate 8 provides a support surface for the positioning member 7, a drill bit rotation mounting positioning seat 10 is provided on the slotting positioning mechanism body 1, and a slotting drill bit 11 is installed on the drill bit rotation mounting positioning seat 10, and the drill bit rotation mounting positioning seat 10 is provided with a slotting drill bit 11. A C-shaped positioning piece 2 is symmetrically and movably connected to the seat 10, and a connecting sleeve 3 is fixed to the outside of the C-shaped positioning piece 2 through a threaded structure, and positioning adjustment seats 4 are respectively fixed on two opposite sides of the connecting sleeve 3, and first movable limiting holes 402 are respectively opened on the outer side surfaces of the positioning adjustment seat 4, and limiting rods 404 parallel to each other are also fixed and connected at uniform intervals on the inner side of the positioning adjustment seat 4. This structure enables the positioning adjustment seat 4 to firmly position the limiting rods 404. The positioning adjustment seat 4 is fixed relative to the C-shaped positioning piece 2 through the connecting sleeve 3, so that the positioning adjustment seat 4 is fixed to the two opposite sides of the drill bit rotation installation positioning seat 10. After the C-shaped positioning piece 2 is spliced ​​through two C-shaped structures, it can be fastened to the drill bit rotation installation positioning seat 10 through the connecting sleeve 3, so that the positioning adjustment seat 4 can be fixed to the drill bit rotation installation positioning seat 10. The joint seat 4 can rotate relative to the drill bit rotation installation positioning seat 10 to adjust the position of the positioning adjustment seat 4. The positioning adjustment seat 4 is movably engaged with a movable seat 5 and a slotting depth control plate 403, and the movable seat 5 and the slotting depth control plate 403 are movably penetrated and matched with the limit rod 404. A protruding structure that interacts with the first movable limit hole 402 is provided on the outer side of the slotting depth control plate 403. This structure allows the movable seat 5 and the slotting depth control plate 403 to be moved up and down in the positioning adjustment seat 4 through the limit rod 404. The slotting depth control plate 403 can accurately control the position of the slotting depth control plate 403 through the position of the protruding part relative to the first movable limit hole 402, so that the slotting depth control plate 403 can control the movable seat 5. The rising range is controlled, and then the rising position of the positioning member 7 is controlled to realize the control of the groove depth. A second movable limiting hole 405 is opened at the bottom of the positioning adjustment seat 4, and the positioning adjustment seat 4 is movably penetrated by a connecting plate 6 through the second movable limiting hole 405. The connecting plate 6 is movably limited through the second movable limiting hole 405. The upper end of the connecting plate 6 is engaged in the movable seat 5 by the bottom of the movable seat 5, and a transverse adjustment screw 501 that cooperates with the connecting plate 6 through a threaded structure is rotatably installed in the movable seat 5, and the outer rotating handle of the transverse adjustment screw 501 passes through the first movable limiting hole 402 and is placed outside the positioning adjustment seat 4. This structure can adjust the position of the connecting plate 6 in the movable seat 5 by rotating the transverse adjustment screw 501.Thereby, the spacing of the positioning members 7 is controlled. When the side portion of the workpiece 9 is grooved, the positioning members 7 can be used for clamping and positioning to ensure the accuracy of the grooves. The positioning members 7 are fixed to the opposite sides of the connecting plate 6. The positioning members 7 are of a Z-shaped structure. The opposite sides and the lower sides of the positioning members 7 are installed with sliding balls 701. The sliding balls 701 are used for auxiliary movement of the positioning members 7. The groove depth control plate 403 is located at the upper end of the movable seat 5, and the top of the positioning adjustment seat 4 is penetrated by a longitudinal adjustment screw 401 rotatably connected to the groove depth control plate 403. This structure rotates the longitudinal adjustment screw 401 to make the longitudinal adjustment screw 401 Under the positioning of the positioning adjustment seat 4, the positioning adjustment seat 4 rotates to achieve up and down movement, so that the longitudinal adjustment screw 401 drives the slotting depth control plate 403 to move up and down. When the positioning member 7 is clamped on both sides of the workpiece 9, the positioning member 7 is supported on the workpiece 9 through the bottom surface above the Z-shaped structure, or the bottom surface below the positioning member 7 is directly supported on the workpiece 9 to assist the movement of the slotting. When the slotting drill bit 11 slots the workpiece 9, the slotting drill bit 11 gradually penetrates into the workpiece 9, and the positioning member 7 gradually moves through the cooperation of the movable seat 5 and the limit rod 404 until the movable seat 5 contacts the bottom surface of the slotting depth control plate 403. At this time, the slotting drill bit 11 cannot continue to penetrate, thereby controlling the slotting depth.

[0021] Working principle: When using the slotting positioning mechanism for drill processing, first place the slotting positioning plate 8 at the position where the workpiece 9 needs to be slotted. When the slotting drill 11 is slotting the workpiece 9, the drill is rotated to install the positioning seat 10 and move it to the position to be slotted. At this time, the slotting positioning mechanism body 1 is supported on the workpiece 9 by the bottom surface below the positioning member 7, or the positioning member 7 is adjusted relative to the movable seat 5 by the lateral adjustment screw 501, so that the positioning member 7 is clamped on both sides of the workpiece 9, and the connecting plate 6 plays a role of active connection between the movable seat 5 and the positioning member 7. The second active limiting hole 405 is used for the active limiting processing of the connecting plate 6. The upper bottom surface of the positioning member 7 is supported on the workpiece 9. When the slotting drill 11 is slotting, the sliding ball 701 assists the positioning member 7 to move relative to the workpiece 9, making the slotting smoother. The grooved drill 11 gradually penetrates into the workpiece 9, and the movable seat 5 gradually rises under the limit of the limit rod 404 until the movable seat 5 contacts the grooved depth control plate 403, and the rising of the positioning member 7 is stopped. At this time, the grooved drill 11 cannot go deeper, and the groove depth is controlled. The longitudinal adjustment screw 401 rotates relative to the positioning adjustment seat 4 to control the position of the grooved depth control plate 403. The first movable limiting hole 402 is used for the limiting treatment of the outer protruding structure of the grooved depth control plate 403 and the transverse adjustment screw 501. The threaded connection between the connecting sleeve 3 and the C-shaped positioning member 2 allows the C-shaped positioning member 2 to be tightened relative to the drill bit rotation installation positioning seat 10, so that the positioning adjustment seat 4 can rotate relative to the drill bit rotation installation positioning seat 10 to prevent the positioning member 7 from being blocked, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
