Description

Boring cutter hole inner hole machining clamp

Technical Field

The utility model relates to a robot parts machining field, concretely relates to boring cutter downthehole spot facing work anchor clamps.

Background

The boring cutter is one kind of boring cutter, generally a round handle, and a square cutter rod is also used for a larger workpiece, and the most common occasions are inner hole processing, hole expanding, profiling and the like. Tools with one or two cutting parts, specially adapted for roughing, semi-finishing or finishing existing holes. The boring tool may be used on a boring machine, a lathe or a milling machine. Due to different clamping modes, the part has various forms such as a square handle, a Morse taper handle, a 7:24 taper handle and the like. The double-edge boring cutter has two cutter teeth which are distributed on two sides of the center and cut simultaneously, and because radial forces generated during cutting are balanced, the cutting amount can be increased, and the production efficiency is high. The double-blade boring cutter is divided into a floating boring cutter and a fixed boring cutter according to whether the blade floats on the boring rod or not. The floating boring cutter is suitable for finish machining of holes. It is practically equivalent to a reamer and can bore holes with high dimensional accuracy and smooth surfaces, but cannot correct the linearity deviations of the holes. In order to increase the regrinding times, floating boring cutters are often made with adjustable structures. In the process of machining robot parts, a part needs to be machined by using a boring cutter, and therefore a boring cutter hole inner hole machining clamp matched with the boring cutter needs to be designed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a to current robot part add man-hour drilling diameter not enough need carry out the boring cutter and carry out the reaming operation to the hole and designed a boring cutter downthehole spot facing work anchor clamps.

A boring cutter hole inner hole machining clamp comprises:

the main clamp body is divided into three parts, wherein the first part is a cylinder, a vertical surface is cut from the top surface, the second part is in a round cake shape, and the third part is a cylinder;

the first part of the main clamp body is vertically provided with an inner hole processing hole downwards from the cutting surface;

the cover plate is in a strip shape and is arranged on the cutting surface of the main clamp body, and the top surface of the cover plate is provided with a cover plate drilling hole which is matched with the main clamp body to work through a bolt;

the cover plate is drilled through the cover plate from the top surface of the cover plate.

Preferably, the first part and the second part of the main clamp body are cylinders with the same diameter;

the third part is a hollow cylinder with the diameter smaller than that of the first part and the circle center overlapped with that of the first part;

the first part, the second part and the third part are integrally formed.

Preferably, the center of the top surface of the first part, which is in the shape of a cylinder, is provided with a processing groove, the processing groove is U-shaped, the U-shaped opening is communicated with the cutting surface, and the radius of the circular arc at the bottom of the U-shaped part is the same as the inner diameter of the third part.

Preferably, the bottom of the inner hole machining hole is also provided with an over-drilling hole, and the diameter of the over-drilling hole is larger than that of the cover plate drilling hole and smaller than that of the inner hole machining hole.

The beneficial effects of the utility model reside in that: the main clamp body and the cover plate are matched to process parts quickly and vertically, the processing groove in the side face facilitates the use of the same clamp to process parts for multiple times and accelerate the forming speed of the parts, the times of the clamp on the parts are reduced, and the production convenience is improved.

Drawings

FIG. 1 is a schematic view of a main clamp model of the present invention;

FIG. 2 is a drawing of the side of the utility model during the closing process;

FIG. 3 is a schematic view of the components of the present invention;

in the figure: 1. the machining method comprises the following steps of main clamp body 2, cutting surface 3, inner hole machining hole 4, over-drilling hole 5, machining groove 6, machining groove 7, third part 8, part 9, cover plate 10 and cover plate drilling hole.

Detailed Description

The technical solution of the present invention is further specifically described below by way of specific embodiments and with reference to the accompanying drawings.

Example 1

As shown in fig. 1 and 2, when the boring hole machining fixture of the present invention is manufactured, a cylinder metal is first selected as a main body of the main clamp 1, and one end of the cylinder is shrunk to form a third portion 7 of the main clamp 1; the other end of the uncut cylindrical body is perpendicularly cut from the top surface of the cylindrical body toward the cut end, and the cylindrical body is left with a partial thickness as a processing groove 6 in the perpendicular cutting.

And defining the cut plane as a cutting surface 2, vertically punching from the top surface of the cutting surface 2 to the cylindrical surface to form an inner hole machining hole 3, and machining a through drilling hole 4 at the bottom surface of the inner hole machining hole 3.

The drilling operation is performed from the top surface of the cylinder where the first part is located and extends from the drill hole to the cutting surface 2 to form a U-shaped machining groove 5, wherein the drill hole is drilled at the center of the cylinder.

The third portion 7 is drilled to form a hollow cylinder.

Two screw holes are arranged on the cutting surface 2.

And another area is provided with a strip-shaped metal plate, a hole is drilled at the central position of the metal plate to serve as a cover plate drilling hole 10, the metal plate serves as a cover plate 9, and two screw holes matched with the screw holes of the first part cutting surface 2 of the main clamp body 1 are drilled on the cover plate 9 to ensure that the cover plate 9 is matched with the main clamp body 1.

Use the utility model discloses a boring cutter downthehole spot facing work anchor clamps will be put into hole spot facing work 3 like the part 8 that fig. 3 is shown, because the size at 8 tops of part is less than apron drilling 10, consequently when the cover is established to the cover, embolias apron drilling 10 with part 8 in, when apron 9 carries out the screw and looks for right time, part 8 can together be aligned.

After the cover plate 9 is fixed, the cover plate is placed into a boring cutter, and the main clamp body 1 is clamped by the third part 7 for processing.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
