Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a composite drill preparation and grinding equipment. Background Technology

[0002] In the preparation of composite drills, grinding is the core process that determines their quality and value. With increasing market demand, the requirements for the production efficiency and quality of composite drills are constantly rising, and the performance of existing grinding equipment has become a key factor restricting large-scale production. Currently, most mainstream composite drill grinding equipment adopts a single grinding wheel structure, completing the operation by fixing the drill body and adjusting its relative position to the high-speed rotating grinding wheel. This type of equipment has significant limitations: First, the grinding efficiency is extremely low; a single wheel can only process a localized area of ​​the drill body at a time. For multi-faceted or multi-process composite drills, repeated adjustments to the posture or wheel replacements are necessary, resulting in long non-processing waiting times and making it difficult to meet the needs of mass production. Second, the process continuity is poor; multiple processes require manual transfer or wheel replacement, easily introducing positioning errors, and frequent start-stop cycles affect equipment lifespan. Third, it lacks adaptability, making it difficult to match the diverse grinding parameter requirements of different specifications of composite drills, resulting in high debugging costs. Therefore, this utility model provides a composite drill preparation grinding device. Utility Model Content

It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0018] like Figure 1 As shown, a composite drill preparation and grinding device includes: a base 1, a clamping mechanism and a support seat 2 located on one side of the clamping mechanism that can move laterally; two longitudinally movable and independent sliding seats 3 are symmetrically arranged on the support seat 2; a vertically movable lifting seat 4 is arranged on the sliding seat 3; a grinding wheel 17 is connected to the bottom of the lifting seat 4, and the grinding wheel 17 can rotate actively. The two grinding wheels 17 are located on both sides of the clamping mechanism and can grind the drill body located on the clamping mechanism respectively, thereby improving the grinding efficiency. The support seat 2, sliding seats 3 and lifting seat 4 are moved by a moving mechanism, which can adopt mature technical solutions such as lead screw assemblies and cylinders.

[0019] Among them, such as Figures 2 to 4 As shown, the clamping mechanism includes a fixed seat 5 fixedly mounted on the base 1. The fixed seat 5 has a through hole in the center, an installation groove in the bottom, and several sliding grooves evenly distributed along its circumference in the top. The inner end of the sliding groove communicates with the through hole, and the bottom communicates with the installation groove.

[0020] like Figure 5 As shown, a rotatable rotating ring 6 is provided in the mounting groove. The top surface of the rotating ring 6 is provided with a spiral connecting protrusion 7, and the bottom is provided with gear teeth 8. The gear teeth 8 are arranged radially along the rotating ring 6. A rotatable gear 9 is also provided in the mounting groove. The gear 9 meshes with the gear teeth 8 and is connected to the drive device 10 provided in the base 1 to drive the rotating ring 6 to rotate.

[0021] Specifically, the mounting base 5 has a raised ring 14 surrounding the through hole within the mounting groove, and the space between the raised ring 14 and the inner wall of the mounting base 5 forms the mounting space for the rotating ring. Simultaneously, a sealing plate 15 is also provided within the mounting groove. The sealing plate 15 has an opening at its center corresponding to the through hole, and its top has a protrusion 16 surrounding the opening and corresponding to the raised ring 14.

[0023] A clamping block 11 is slidably disposed within the sliding groove. The bottom of the clamping block 11 has several connecting grooves 12 that are adapted to the connecting protrusion 7. The clamping block 11 is connected to the rotating ring 6 by engaging with the connecting protrusion 7 through the connecting grooves 12. When the connecting protrusion 7 rotates, it will drive the clamping block 11 to move along the sliding groove, thereby clamping or releasing.

[0024] A liftable support block 13 is installed inside the through hole. The support block 13 is always located below the clamping block 11, serving to support the drill body.
