Referring to fig. 1-2, there is shown a guide sleeve cup holder 1 for placement in a cutter cup 3 of a swing arm 6 type magazine 5 to accommodate a drill guide sleeve 2, which can be assembled with the cutter cup 3 as well as accommodate the drill guide sleeve 2, thereby achieving the purpose of placing the drill guide sleeve 2 in the magazine 5. The guide sleeve cup seat 1 comprises a cup body matched with the corresponding cutter cup 3, an axially-through hole is formed in the cup body, the tail end 102 of the through hole is matched with the cutter head blind rivet 4 in the corresponding cutter cup 3 to achieve positioning, and the head end 101 of the through hole is matched with the head end of the drill guide sleeve 2 to be accommodated so as to be sleeved conveniently.
After the drill guide sleeve 2 is placed in the guide sleeve cup seat 1, in order to avoid random movement of the drill guide sleeve 2, a corresponding structure is required to be arranged for limiting. If set up the spacing subassembly 107 of activity on the cup body, spacing subassembly 107 can with treat the drill tip guide pin bushing 2 adaptation that holds, and the spacing action cooperation of spacing subassembly 107 is taken out, the operation of putting into triggers by corresponding drill tip guide pin bushing 2, promptly when treating to hold drill tip guide pin bushing 2 and can trigger spacing subassembly 107 putting into guide pin bushing cup 1's in-process, make the cooperation between spacing subassembly 107 and the drill tip guide pin bushing 2 form limiting action, avoid drill tip guide pin bushing 2 random activity or break away from and drop. After the drill guide sleeve 2 to be accommodated is placed in the guide sleeve holder, the drill guide sleeve 2 needs to be taken out in the subsequent guide sleeve replacement operation, the limiting component 107 can be triggered in the taking-out process, and the limiting action between the limiting component 107 and the drill guide sleeve 2 is relieved, so that the drill guide sleeve 2 can be smoothly taken out.
Therefore, the drill tip guide sleeve 2 can be placed on the tool magazine 5 through the guide sleeve cup seat 1, a structural basis is provided for an automatic technical scheme without manual guide sleeve switching, and the problems of space occupation, mechanism action interference and the like caused by the scheme of setting the guide sleeve magazine are effectively avoided.
In view of the matching structure of the existing knife cup 3, the cup body of the guide sleeve cup holder 1 is generally conical, a clearance step 106 is formed between the tail end 102 (smaller periphery) and the head end 101 of the through hole, and the clearance step 106 is arranged to simplify the manufacturing process of the cup body and reduce the cost. The limiting component 107 can be a ball head elastic plunger, the wall surface of the cup body is provided with a transverse hole 103, the ball head elastic plunger is installed in the transverse hole 103 in an adaptive mode, a ball head at the front end of the ball head elastic plunger is used for limiting, and the ball head can be affected by operating force to retract in the process of putting in or taking out the drill guide sleeve 2, so that the interference of the axial in-and-out action of the drill guide sleeve 2 is avoided. When the drill guide sleeve 2 is in a state of being assembled with the guide sleeve cup holder 1, the drill guide sleeve 2 has a corresponding structure, and the ball head is just abducted to cancel the acting force on the ball head, so that the ball head extends out and is matched with the drill guide sleeve 2 to be limited, and the drill guide sleeve 2 is prevented from being separated from the guide sleeve cup holder 1 at will.
Referring to the attached drawings 3-6, a drill guide sleeve 2 correspondingly matched with each guide sleeve cup seat 1 is provided, the outer wall of the head end of the drill guide sleeve 2 is provided with a limit matching part 202, the limit matching part 202 is matched with a corresponding limit component 107 to realize the positioning of the drill guide sleeve 2, and the opening and closing of the limit component 107 and the limit matching part 202 are triggered when the drill guide sleeve 2 enters and exits the guide sleeve cup seat 1; the outer wall of the tail end of the drill guide sleeve 2 is provided with a clamping groove for the swing arm 6 of the tool magazine 5 to operate.
General deep hole drill 11 guide pin bushing head end 200 is cylindricly, and guide pin bushing tail end 201 then sets up the great (being greater than the round head end) flange of radial dimension, and deep hole drill 11 guide pin bushing 2 head end city is cylindricly, and the tail end then sets up the great (being greater than the round head end) flange of radial dimension. By taking the limiting component 107 arranged on the guide sleeve cup seat 1 as a ball head elastic plunger as an example, the outer wall of the head end of the drill guide sleeve 2 is correspondingly provided with an annular groove in a surrounding way, the annular groove has the advantages that the axial direction of the drill guide sleeve 2 corresponds to the guide sleeve cup seat 1, the positioning and guiding are not required to be carried out in the circumferential direction, and the ball head and the annular groove can be matched randomly in the circumferential direction.
