Abstract

The utility model provides a clamp used for a tapered face vertical borehole. The clamp comprises a clamp body provided with a tapered inner hole, wherein a guide hole is formed in the clamp body, a center line of the guide hole is parallel to that of the tapered hole, and one end of the guide hole in the clamp body is communicated with the tapered hole. A drill is driven to move along the vertical direction due to the fact that the guide hole is arranged and the center line of the guide hole is parallel to that of a tapered face of a workpiece, the drill is prevented from sliding on the tapered face of the workpiece, machining of a vertical hole in the tapered face of the workpiece is realized, and normal production is guaranteed.

Description

A kind of anchor clamps for conical surface vertical drilling

Technical field

The utility model belongs to the equipment Technology field, relates to a kind of anchor clamps for boring, is specifically related to a kind of anchor clamps for conical surface vertical drilling, can realize vertical drilling at the less conical surface of tapering, has solved the difficult problem that the conical surface can't vertical drilling.

Background technology

In the manufacturing process of some equipment, can run into a difficult problem of carrying out vertical drilling at the conical surface.When the conical surface carried out vertical drilling, because conical surface band is gradient, drill bit can slip along with the conical surface at the conical surface and can't realize vertical drilling at the conical surface, so that the manufacturing of equipment can't be carried out, also can't realize designer's intention, affects the normal use of equipment.

Summary of the invention

The purpose of this utility model provides a kind of anchor clamps for conical surface vertical drilling, forces drill bit to bore along conical surface vertical direction moving, does not slip with the conical surface, and the assurance device fabrication is normally carried out.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of anchor clamps for conical surface vertical drilling, comprise that endoporus is the clamp body of taper hole, be processed with the pilot hole that center line parallels with the taper hole center line on the clamp body, the end that pilot hole is positioned at clamp body communicates with taper hole.

One end of described pilot hole is positioned on the end face of clamp body at the less end place of locating hole diameter, and the other end of pilot hole stretches in the clamp body, and communicates with locating hole.

The taper hole that the utility model anchor clamps adopt and institute's processing work conical surface is suitable is as locating hole, anchor clamps and the workpiece conical surface are fitted locates, force drill bit to move in the vertical direction by center line with the pilot hole that workpiece conical surface center line parallels, avoided the slippage of drill bit on the workpiece conical surface, realize the processing of upright opening on the workpiece conical surface, guarantee to produce and normally carry out.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

In the actual production process, usually need to carry out vertical drilling at the workpiece that is shaped as cone shown in Figure 11, namely the conical surface at workpiece 1 processes the hole 2 that center line parallels with the cone center line, as shown in Figure 2.Adopt prior art on the conical surface of workpiece 1 during machining hole 2, drill bit 3 front ends are when touching the conical surface of workpiece 1, only have a cutting edge to contact with workpiece 1 in two cutting edges of drill bit 3 front ends, drill bit 3 discontinuity equalizations, cause drill bit 3 to slide along the conical surface of workpiece 1, P direction among drill bit 3 glide directions such as Fig. 3 causes drill bit 3 not get out the hole 2 that center line parallels with the cone center line at workpiece 1 conical surface.

For solving above-mentioned problems of the prior art, the utility model provides a kind of anchor clamps shown in Figure 4 that can assist drill bit 3 to process the vertical hole of center line 2 at workpiece 1 conical surface, the clamp body 4 that comprises annular, the endoporus of clamp body 4 is taper hole, the cone angle of the cone angle of this taper hole and workpiece 1 male cone (strobilus masculinus) is suitable, becomes locating hole 5; Be processed with the pilot hole 6 that center line parallels with locating hole 5 center lines on the end face of clamp body 4, one end of pilot hole 6 is positioned on the end face of clamp body 4 at the less end place of locating hole 5 diameters, the other end of pilot hole 6 stretches in the clamp body 4, and communicates with locating hole 5.Need to be on the conical surface of workpiece 1 machining center line during with hole 2 that conical surface center line parallels, select the suitable anchor clamps of the cone angle of locating hole 5 and workpiece 1 cone angle, and the centre-to-centre spacing between pilot hole 6 and the locating hole 5 meets the requirement of centre-to-centre spacing between hole 2 and workpiece 1 center line on these anchor clamps; These anchor clamps are enclosed within workpiece 1 surface, locating hole 5 is located with the cone match of workpiece 1, form a kind of similar effect in plane boring, as shown in Figure 5, fixation workpiece 1 and anchor clamps, make not produce between the two and relatively move, rotary drilling-head 3 is stretched in the pilot hole 6, the cutting edge of drill bit 3 cuts the conical surface of workpiece 1, because the positive action of pilot hole 6, force drill bit 3 to move along pilot hole 6, and no longer along the conical surface slippage of workpiece 1, realize the hole 2 that the machining center line parallels with the taper hole center line on the conical surface.

The utility model clamp structure is simple, and is convenient and practical, can be on the conical surface the vertical hole of machining center line.

Above-described only is preferred embodiment of the present utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, as the common practise of this area, can also make other equivalent modifications and improvement, also should be considered as protection domain of the present utility model.
