Abstract
The utility model relates to a clamp for drilling spiral distribution holes on a bush, comprising a drill bush (13), a rotating shaft (10), a gear sleeve (9) and a circular ring (8) which is fixed at one end of the rotating shaft (10). The drill bush (13) is internally provided with two fixed rings (14), two linear bearings (3) are sheathed on the rotating shaft (10), the front end of the rotating shaft (10) is provided with a convex ring (11), left screw threads are connected with nuts (1), the gear sleeve (9) is provided with helical teeth, a conical head pin (4) is fixed on the drill bush (13); the outer circular surface of the circular ring (8) is provided with a plurality of axial grooves (6) and through holes of the drill bush, pins (5) are arranged in the through holes and connected on the drill bush (13), the front ends of the pins (5) can overcome the elasticity of a shrapnel and extend into the axial grooves (6); and the front end of the drill bush (13) is provided with a drill hole (2). The clamp has high efficiency and high precision to drill spiral line through holes for the bush.
Description
Technical field
The utility model relates to a kind of anchor clamps, especially a kind of anchor clamps that bore threaded hole on lining.
Background technology
Anchor clamps are widely used on the machining.Workpiece is through processing on lathe after the clamp.Often run on the industrial production lining is bored several on the lining hand of helix and several through holes.The processing method that people use always is first setting-out on lining, determines the particular location in good each hole, lining is fixed with anchor clamps again, starts drilling machine and is holed in the setting-out position.Above-mentioned boring trouble, operation is many, greatly reduces production efficiency, and because the human factor influence is very big, drilling accuracy often is difficult to meet the demands, so the qualification rate of product is low.
The utility model content
It is low that the purpose of this utility model solves lining brill threaded hole efficient exactly, and the low problem of product percent of pass, provides a kind of lining auger shell to revolve the hole anchor clamps that are equally spaced.
The technical solution adopted in the utility model is: the lining auger shell is revolved the hole anchor clamps that are equally spaced, it is characterized in that it comprises drill bushing, is sleeved on rotating shaft in the drill bushing, is fixed on the tooth cover at rotating shaft middle part and is fixed on the annulus of rotating shaft one end, be provided with two retainer rings in the described drill bushing, be set with two linear bearings in the rotating shaft, linear bearing is fixed on the retainer ring, rotating shaft can be relatively rotated with straight line with drill bushing move; The front end of rotating shaft is provided with bulge loop, and the left end thread connection has nut, cooperates with bulge loop by nut to clamp lining; Tooth is arranged with helical tooth, and drill bushing has the conehead pin in tooth cover fixed-site, and conehead pin front end stretches between the helical tooth of tooth cover; The annulus periphery is provided with several axial grooves, and drill bushing is provided with through hole at the correspondence position of annulus, is provided with pin in the through hole, and pin is connected on the drill bushing by shell fragment, and the elastic force that the front end of pin can overcome shell fragment stretches in the axial groove; The front end of drill bushing is provided with boring.
Adopt technique scheme, when lining is bored threaded hole, lining is sleeved on the rotating shaft left end, and fixes with nut and bulge loop.This moment, pad stretched in the axial groove of annulus pin, stretched into boring with the drilling machine drill bit, to lining boring, bore what a hole after, withdraw from drill bit, rotating shaft, rotating shaft is just rotated and is moved to the left, when moving to the next axial groove of pin correspondence, the extruding pin, make pin stretch into axial groove, rotating shaft is at this moment no longer rotated, and again the drill bit of drilling machine is stretched into boring, bore next through hole, can bore a plurality of threaded hole with this.
The utility model beneficial effect is: the utility model is by conehead pin and tooth cover and cooperate and pin cooperates with the annulus axial groove, can on lining, bore the through hole of helix, distance between the all-pass hole can be by the distance control between the axial groove, therefore the utility model can be to the convenient helix hole of boring fast of lining, the efficient height, the precision height.

Fig. 1 is the utility model structural representation.
Among the figure, 1, nut, 2, boring, 3, linear bearing, 4, the conehead pin, 5, pin, 6, axial groove, 7, handle, 8, annulus, 9, the tooth cover, 10, rotating shaft, 11, bulge loop, 12, lining, 13, drill bushing, 14, retainer ring.
The specific embodiment
The utility model lining auger shell is revolved distribution hole anchor clamps, as shown in Figure 1, it comprises drill bushing 13, be sleeved on rotating shaft 10 in the drill bushing 13, be fixed on the tooth cover 9 at rotating shaft 10 middle parts and be fixed on the annulus 8 of rotating shaft 10 1 ends, be provided with two retainer rings 14 in the described drill bushing 13, be set with two linear bearings 3 in the rotating shaft 10, linear bearing 3 is fixed on the retainer ring 14, rotating shaft 10 can be relatively rotated with straight line with drill bushing 13 move; The front end of rotating shaft 10 is provided with bulge loop 11, and the left end thread connection has nut 1, cooperates with bulge loop 11 by nut 1 to clamp lining 12; Tooth cover 9 is provided with helical tooth, and drill bushing 13 overlaps 9 fixed-site at tooth conehead pin 4, and conehead pin 4 front ends stretch between the helical tooth of tooth cover 9; Annulus 8 peripheries are provided with several axial grooves, and drill bushing is provided with through hole at the correspondence position of annulus 8, are provided with pin 5 in the through hole, and pin 5 is connected on the drill bushing 13 by shell fragment, and the elastic force that the front end of pin 5 can overcome shell fragment stretches in the axial groove 6; The front end of drill bushing 13 is provided with boring 2.
For making things convenient for the rotation of countershaft 10, be connected with handle 7 at the right-hand member of rotating shaft 10.
