Abstract
The utility model discloses a hand drill, which can not only chamfer but also get rid of burrs. The utility model comprises a lock sleeve (2) and a lock gripping head (3) which are used to hold a drill bit (1). The utility model is characterized in that the lock sleeve (2) is connected with a screw (5) which is positioned in a hand-held sleeve(6) through a pin (4), the hand-held sleeve (6) is fixed with a sliding screw (7) whose head is positioned in a helix sliding slot of the screw (5), and a spring (8) is arranged on the section of the screw (5) between the lock sleeve (2) and the hand-held sleeve (6). The utility model has the advantages of simple structure, small size, convenient operation, high processing efficiency, good quality and so on and may be used in the chamfering and deburring of parts of cavity thin walls as well as to the processing of the chamfering and deburring of the surface holes of different sorts of parts with different sizes.
Description
Technical field:
The utility model relates to a kind of part aperture machining tool, especially a kind of hand drill that is used for part aperture edge chamfer and deburring.
Background technology:
In the process of the interior pit aperture chamfering of cavity thin wall component and deburring, because such part shape is not too regular, intracavity space is narrow limited, in the man-hour that adds of carrying out aperture chamfering and deburring, can not use electric hand drill, more can't on drilling machine, carry out, and it is inboard and can't go to the greatest extent to use file can make the aperture burr of routing up from part thin-walled medial surface plough under the aperture, and uses scraper can't operate by spatial constraints.Normally hand-held at present drill bit, roll over moving deburring, and the gripping mode of drill bit also can only be that thumb, middle finger and the third finger pinch drill bit, pin drill bit afterbody termination by forefinger and apply axial force, stranding tosses about in bed moving deburring, this method not only working (machining) efficiency is low, and crudy is poor, and the operator is easy to generate industrial accident in process.Therefore inwall orifice edge chamfering and the deburring to the cavity thin wall component is a processing difficult problem always.
Summary of the invention:
The purpose of this utility model is: a kind of volume is little, easy to operate and crudy the is good chamfering and the hand drill of deburring are provided, thereby overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises lock sleeve and the locking chuck that is used for clamping drilling bit, lock sleeve is connected on the screw rod by pin, screw rod is contained in the hand-held cover, is fixed with sliding screw hand-held putting, and the head of sliding screw is contained in the spiral chute of screw rod; On that section screw rod between lock sleeve and the hand-held cover, spring is housed.
Be provided with baffle plate in hand-held cover, baffle plate is connected on the screw rod by screw.
Compared with prior art, of the present utility model simple in structure, be easy to realize; And volume is little, is convenient to process the narrow limited cavity thin wall component of intracavity space, and operation easily, the working (machining) efficiency height, the process velocity of the comparable prior art of its process velocity improves 2～4 times, and the aperture chamfering of processing is regular, any surface finish, crudy is higher.
The utility model can also be used for the part outer surface orifice chamfering of various different volumes and the processing of deburring except that being used to process the lumen orifice of cavity thin wall component, in particular for the aperture chamfering of the heavy parts that is difficult for moving and the processing of deburring
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: as shown in Figure 1, it comprises lock sleeve 2 and the locking chuck 3 that is used for clamping drilling bit 1, connect for tapered thread between lock sleeve 2 and the locking chuck 3, lock sleeve 2 is connected on the anterior termination of screw rod 5 by pin 4, the afterbody of screw rod 5 is contained in the hand-held cover 6, on hand-held cover 6, be fixed with sliding screw 7, and the head of sliding screw 7 is contained in the spiral chute of screw rod 5; On that section screw rod 5 between lock sleeve 2 and the hand-held cover 6 spring 8 is housed, spring 8 is used for 5 reset responses of screw rod; Be provided with baffle plate 10 in hand-held cover 6, baffle plate 10 is connected on the screw rod 5 by screw 9, and baffle plate 10 is used for carrying out spacing to screw rod 5.
Add man-hour, unscrew lock sleeve 2 earlier, locking chuck 3 is unclamped, drill bit 1 is inserted in the locking chuck 3, screw lock sleeve 2 then, locking chuck 3 is clamped, this moment, drill bit 1 was fixed in the locking chuck 3 firmly; Hold hand-held cover 6 then, the aperture that the head perpendicular alignmnet of drill bit 1 need be processed, firmly press down, this moment, hand-held cover 6 moved down, and sliding screw 7 moves down with hand-held cover 6, because the head of sliding screw 7 is contained in the spiral chute of screw rod 5, therefore screw rod 5 is by the head driven rotary of sliding screw 7, screw rod 5 drives lock sleeve 2 and locking chuck 3 rotations, and locking chuck 3 drives drill bit 1 rotation again, thus the process operation that carries out chamfering and deburring.After machining, hold hand-held cover 6 and lift, spring 8 will be handed cover 6 and automatically reset, and prepare processing next time.
Claims (2)
1. the hand drill of chamfering and deburring, it comprises lock sleeve (2) and the locking chuck (3) that is used for clamping drilling bit (1), it is characterized in that: lock sleeve (2) is connected on the screw rod (5) by pin (4), screw rod (5) is contained in the hand-held cover (6), be fixed with sliding screw (7) on hand-held cover (6), the head of sliding screw (7) is contained in the spiral chute of screw rod (5); On that section screw rod (5) between lock sleeve (2) and the hand-held cover (6), spring (8) is housed.
