Abstract
The utility model discloses a circular ring perforating device which comprises a drilling machine drill bit, a drill bit clamping sleeve and a workpiece circular ring. A fixing block is fixedly connected under the drill bit clamping sleeve and provided with a central hole, a clamping seat is arranged under the fixing block, the fixing block is fixedly connected with the clamping seat through a first buffering spring and a second buffering spring, the clamping seat is provided with a first convex corner and a second convex corner, the center distance between the first convex corner and the second convex corner is equal to the outer circle diameter of the workpiece circular ring, the clamping seat is provided with a drill sleeve, the drilling machine drill bit penetrates through the central hole in the fixing block and the drill sleeve in sequence and then is fixedly clamped by the drill bit clamping sleeve, a storage groove is formed under the clamping seat, and the workpiece circular ring is placed in the storage groove. By means of the circular ring perforating device, when holes are perforated in a large number of circular rings, clamping and perforating are carried out at the same time, a clamp does not need to be mounted and dismounted repeatedly, and production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of perforating device, particularly a kind of annulus perforating device.
Background technology
The punching of workpiece, particularly annulus, general operation are to use earlier clamp, punch on request with punch device again, picture plane brill, bench drill, electric drill etc. wherein with the clamp workpiece time, normally need to process a workpiece to use lower clamp, lay down after intact,, load onto again again during second workpiece to processing, when the batch workpiece of need processing is big, repeatability load onto, lay down anchor clamps, production efficiency is very low.
The utility model content
For solving the problems of the technologies described above, when the utility model provides a kind of large batch of annulus to punch, need not the annulus perforating device that anchor clamps were loaded onto, laid down to repeatability.
For achieving the above object, the technical solution of the utility model is: a kind of annulus perforating device, comprise the drilling machine drill bit, the drill bit gripping sleeve, the workpiece annulus, drill bit gripping sleeve below is fixedly connected with fixed block, fixed block is provided with centre bore, the fixed block below is provided with clamping seats, fixedlyed connected with second buffer spring by first buffer spring between fixed block and the clamping seats, clamping seats is provided with first salient angle and second salient angle, centre-to-centre spacing between first salient angle and second salient angle equals the outside diameter of workpiece annulus, clamping seats is provided with drill bushing, the drilling machine drill bit passes centre bore and the drill bushing of fixed block successively and clamps cartridge clip by drill bit and fastens, the clamping seats below is provided with storage tank, and the workpiece annulus places in the storage tank.
The beneficial effects of the utility model are: on the workpiece annulus, clamping and punching are carried out simultaneously, need not be when punching, and anchor clamps are loaded onto, laid down to repeatability, and production efficiency greatly improves.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: drilling machine drill bit 1, drill bit gripping sleeve 2, workpiece annulus 3, fixed block 4, clamping seats 5, first salient angle 51, second salient angle 52, first buffer spring 61, second buffer spring 62, drill bushing 7, storage tank 8.
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of annulus perforating device, comprise drilling machine drill bit 1, drill bit gripping sleeve 2, workpiece annulus 3, drill bit gripping sleeve 2 belows are fixedly connected with fixed block 4, fixed block 4 is provided with centre bore, fixed block 4 belows are provided with clamping seats 5, fixedlyed connected with second buffer spring 62 by first buffer spring 61 between fixed block 4 and the clamping seats 5, clamping seats 5 is provided with first salient angle 51 and second salient angle 52, centre-to-centre spacing between first salient angle 51 and second salient angle 52 equals the outside diameter of workpiece annulus 3, clamping seats 5 is provided with drill bushing 7, drilling machine drill bit 1 passes the centre bore of fixed block 4 and drill bushing 7 successively and is fixedly clamped by drill bit gripping sleeve 2, clamping seats 5 belows are provided with storage tank 8, and workpiece annulus 3 places in the storage tank 8.
Operation principle of the present utility model is: when drilling machine drill bit 1 moves downward, drill bit gripping sleeve 2 acts on together down motion of fixed block 4, when first salient angle 51 on clamping seats 5 does not contact with workpiece annulus 3 with second salient angle 52, first buffer spring 61 and second buffer spring 62 are all in the raw, when first salient angle 51 on the clamping seats 5 contacts with workpiece annulus 3 with second salient angle 52, drilling machine drill bit 1 moves downward again, at this moment, first buffer spring 61 and second buffer spring 62 all are in compressed state, thereby make elastic pressure act on clamping seats 5, clamping seats 5 remakes for workpiece annulus 3, so, make clamping work pieces annulus 3 and in its surface punching for carrying out simultaneously, and beaten behind the hole as long as promote drilling machine drill bit 1, when making a call to the hole of second workpiece, make drilling machine drill bit 1 move downward repetitive operation one time again, production efficiency greatly improves.
