Abstract
The utility model relates to a T-shaped nut and screw hole drilling cramping apparatus, which comprises a base and a movable press plate which are clamped up and down, wherein the movable press plate is connected with the base through a clamping screw [6], the base [1] is provided with a V-shaped groove, the movable press plate [5] is provided with a positioning hole which is in the clearance fit with a drill bit. The utility model can share the function of a drilling jig through drilling the positioning hole on the movable press plate in the cramping apparatus which is clamped up and down, and the positioning hole is larger than the diameter of the drill bit (in the clearance fit), allows the drill bit to pass through, and can determine the position of boreholes. Compared with the prior art, the operation of aligning the positioning hole with the center of a screw hole is much easily rather than the alignment of the drill bit with the center of the screw hole, and the alignment of the drill bit with the positioning hole is also extremely convenient, therefore, the positioning time of the drilling is greatly shortened, and the drilling speed of signal machine is increased to 30 pieces from 12 pieces per hour, thereby improving the working efficiency, simultaneously, the processing precision is relatively improved.
Description
Technical field
The utility model relates to a kind of T type nut tap drill system anchor clamps, especially a kind of T type nut tap drill system anchor clamps of cylindrical shape belong to the metalworking technology field.
Background technology
T type nut is meant that its profile is column, and the screw direction a kind of nut vertical with cylinder, because of its be the T type after bolt cooperates and gain the name, as square column T type nut, cylinder T type nut etc.When the screw of processing column T type nut, prior art is that the screw center is determined in line earlier, with anchor clamps cylindrical nut blank (workpiece) is clipped then, adjusts the center scribing position that makes the drill bit screw again, and anchor clamps and Drilling machines bench plate are fixed, finish boring at last.Wherein anchor clamps comprise fixed pressuring plate (base) and dynamic pressure plate, and dynamic pressure plate is by screw (screw rod) and fixed pressuring plate adjusting mutual edge distance and workpiece is clamped mutually.Because drill bit is suspended in the workpiece top, and is very inconvenient with the screw centrally aligned, so there is the low phenomenon of working (machining) efficiency.
Summary of the invention
At above-mentioned deficiency, the utility model is exactly to propose a kind of T type nut tap drill system anchor clamps that can improve the production work efficiency.
T type nut tap drill system anchor clamps of the present utility model have the base and the dynamic pressure plate that fold up and down, and dynamic pressure plate is connected with base with trip bolt, and said base has a V-shaped groove, and the locating hole with the drill bit matched in clearance is arranged on the said dynamic pressure plate.
The utility model will move clamping plate and stamp locating hole and have the drill jig function concurrently in the anchor clamps that clamp up and down, said locating hole be than bit diameter slightly big (matched in clearance) drill bit is passed and determines the hole of bore position.Compared with the prior art, when operation that locating hole is much easier with drill bit and screw centrally aligned with screw centrally aligned ratio, and drill bit also is very easily with aiming at of locating hole, therefore the utility model is holed and is shortened greatly positioning time, the separate unit penetration rate from per hour 12 bring up to 30, thereby improved work efficiency, simultaneously the also corresponding machining accuracy that improved.
End at V-shaped groove on the said base is equipped with master plate, the structure that props up workpiece end face is arranged on the master plate, master plate is determined the end face of workpiece and the distance at screw center, therefore when operation, can remove from the screw center is decided in the line of workpiece, the operation of during with the clamping of removing workpiece from locating hole being aimed at the screw central point, only need workpiece one end is got final product by sufficient master plate and from the locating hole punching, shortened the clamping workpiece time significantly.
According to practical operation test, utilize bushing plate and master plate after, the scrappage of holing originally drops to 0 from 0.7%.
The structure that props up workpiece end face on the said master plate is to point to the adjusting bolt of workpiece end, can be used to regulate the position of workpiece in V-shaped groove, and to regulate the different eccentric position of workpiece screw, promptly screw is apart from the distance of workpiece end.Though salient point or fixing short column etc. all can be used to prop up workpiece end face and determine the position of workpiece end face on master plate plate face, the master plate, but with the adjusting bolt that can on master plate, use its protrusion height of threaded adjusting, more can be used to determine the different needed positions of workpiece end face, make anchor clamps can be used in the workpiece of more specifications.
T type nut tap drill system anchor clamps of the present utility model, said dynamic pressure plate is supported on the base plane with the cramp bar of the same length in both sides and with bolting, respectively there is screw the locating hole both sides on the dynamic pressure plate, is furnished with the bolt that can withstand workpiece on the screw, the axis of bolt is parallel with the locating hole axis and on same vertical plane, this vertical plane passes through axis of workpiece.Clamping action to workpiece in this structure is by the hold out against enforcement of the bolt on the dynamic pressure plate to workpiece, dynamic pressure plate maintenance level also has certain distance can guarantee locating hole and the requirement of drill bit axiality on the dynamic pressure plate apart from the workpiece cylinder, also can guarantee that drill bit is on the radial line of workpiece and not inclined to one side simultaneously.
The locating hole inboard is lined with sheath on the said dynamic pressure plate, is not subjected to the quick wearing and tearing of drill bit with the protection locating hole.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment, and Fig. 2 is the vertical view of Fig. 1.Among the figure: 1-base, 2-master plate set bolt, 3-master plate, 4-support set, the 5-bushing plate, 6-bushing plate set bolt, 7-cylinder T type nut workpiece, 8-workpiece trip bolt, the 9-drill hole sheath, 10-workpiece eccentric adjusting screw, 11-anchor clamps and platen fixed bolt hole.
The specific embodiment
Be further described below in conjunction with 1,2 pairs of these routine utility models of accompanying drawing.
Respectively fixedly connected bushing plate with the bolt 6 that passes support set by three support sets 4 in one top, the V-shaped groove both sides with base 1 of V-shaped groove with base, 6 support sets of same length make bushing plate maintenance level.On the same vertical plane of axis of workpiece, except that collared hole, also have two screwed holes on the bushing plate respectively in the both sides in hole, two pieces of trip bolts 8 are fixed on cylinder T type nut workpiece 7 in the V-shaped groove by two screwed holes on the bushing plate, the tail end face of the end face of master plate 3 and base V-shaped groove joins, and it is fixing with bolt 2, one screwed hole is arranged on the master plate in addition, screw 10 withstands an end face of workpiece by this screwed hole, can change the position of workpiece screw off-centre by adjustment screw.
During work, the base of these routine device anchor clamps and bushing plate, master plate installed be placed on the Drilling machines bench plate after appropriate, mobile anchor clamps and alignment of shafts location are aimed at afterwards by bolt hole 11 drill bit anchor clamps are fixed on the drilling machine with locating hole on the bushing plate.In V-shaped groove, put into workpiece from no master plate one end, (during the punching of the T type nut of same specification, regulating the master plate screwing when unit one is put into) to determine boring and workpiece end face distance.Fix workpiece with the screw on the bushing plate 8, drill bit is finished tap drill system to cylinder T type nut by interfix hole 9.
