Description

Body boring servicing unit

The utility model relates to a kind of body boring servicing unit.

People often must hole on the body of the big or small caliber of various differences when construction, because if directly hole with artificial electric hand drill, then body rolls easily, operation is had some setbacks, artificial free-hand direct control also can't be drilled in predetermined center and make the hole that is come outbreak out produce skewness simultaneously, at this shortcoming and demand, industry is promptly developed a kind of drilling machine product that is suitable for holing on body, its with electric drill on a body fixed structure, this body fixed structure extends a serobila can tie up the body of desire boring, and mat can provide the effect of auxiliary bore hole therefrom.But, find through the use of reality, therefore and can't fix body really because its employed serobila only is that the body circle is put on the spot,,, makes vibrations when boring and produce skew because the body caliber has difference in size, cause the boring still can't be accurate; At present; though another kind of saw hole machine structure is arranged on the market; see also shown in Figure 1; it is the motor 12 that has a hole saw 11 and power is provided; and a plurality of spring stacks 13 of reduction up and down; other has a bundle serobila 14 in order to the ring body; its occupation mode is to tie up the body of desire processing with these serobila 14 corrals; and in the tight position of circle ring sentence appended latch 15 insert knot serobilas 14 fixing after; a plurality of spring stacks 13 can push against body according to the position; pass through the fixing of these a plurality of spring stacks 13 and serobila 14 in theory; should make the tight position of body and in adding man-hour in the perforate of correct center; yet; in fact its serobila 14 only is to insert knot with latch 15 after tying up body; therefore; still gapped appearance when the body of tight position and can't tightening fully; on the other hand; the purpose of its design spring stack 13 is to be to comply with the body radian to push against body; compress reaction force that its spring 131 produced when yet in fact it pushes against but on the contrary in adding the cutting power that reduces hole saw 11 man-hour; the efficient of perforate is reduced; be it what is more because of serobila 14 can't tight fully position; and the spring stack 13 even the vibration force that can the time be produced along with cutting and the springing phenomenon is arranged; stability when making perforate is not good; there is the phenomenon of disalignment in regular meeting; puzzlement when causing construction often is one of construction quality poor prognostic cause.

In view of this, this creator spy to be being engaged in manufacturing and designing of hardware machinery, the practical experience of being accumulated, further investigation improves, through long-term effort with study, eventually generation of the present utility model.

At the shortcoming that prior art exists, main purpose of the present utility model is to provide a kind of body boring servicing unit, and directly be used on the body and hole, and automatic location drilling position of center line, and can effectively tighten body.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of body boring servicing unit, has a positioning seat, be provided with a right cylinder in its seat surface one side, be provided with tooth-arranging strip one in cylinder, and install the electric drill that to transfer in the right cylinder oscilaltion, it is characterized in that: each corner location place respectively offers screw in positioning seat, being screwed into behind the stay bolt bottom that respectively is spirally connected in each place, bottom surface, corner is the clamping block of arc-curved shape, the bent place of the bottom surface arc of clamping block is provided with continuous tooth bar, and the two adjacent bent places of clamping block arc constitute a semicircular arc relatively; Be provided with an elongated hole thoroughly in positioning seat seat surface center, and place a universal runners, its latter end is provided with screw thread, and after penetrating above-mentioned elongated hole, screw tight locking up and down with a plurality of nuts, its top end has a ball seat hole and fills out and contains a universal drive shaft pearl, and be equipped with a screw spiral shell in its pearl body and wear a connecting screw rod, its end spiral shell knot one is brought nut together, in the fixing end chain hole of serobila of universal runners string knot one.

By the utility model body boring servicing unit, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, the utility model is easy to use, and location drilling is effectively tightened body automatically.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is a drilling machine structural representation commonly used;

Fig. 2 is a structural upright outside drawing of the present utility model;

Fig. 3 is a main member decomposing schematic representation of the present utility model;

Fig. 4 is application schematic diagram one side view of the present utility model;

Fig. 5 is application schematic diagram one front view of the present utility model.

See also Fig. 2, shown in Figure 3, the utility model mainly has a positioning seat 2, is provided with a right cylinder 21 in its seat surface one side, is provided with tooth-arranging strip 211 one in cylinder, and can install the electric drill 22 that can transfer in right cylinder 21 oscilaltions; 2 each corner location place respectively offer screw 23 in positioning seat, and respectively to be screwed into the bottoms that respectively are spirally connected in each place, bottom surface, corner, stay bolt 24 back be the clamping block 3 of arc-curved shape, the bent place of the bottom surface arc of this clamping block 3 is provided with continuous tooth bar 31, the two adjacent bent places of clamping block 3 arcs and constitutes a semicircular arc relatively; Be provided with an elongated hole 25 in positioning seat 2 seat surface center positions, and place a universal runners 4, its latter end is provided with screw thread 41, and can screw tight locking up and down with a plurality of nuts 42 in penetrating above-mentioned elongated hole 25 backs, its top end has a ball seat hole 43 and can fill out and contains a universal drive shaft pearl 44, and is equipped with a screw 441 in its pearl body, and wears a connecting screw rod 45 for spiral shell, its end can cooperate in addition spiral shell knot one to bring nut 46 together, can go here and there a fixedly end chain hole of serobila 5 of knot one in this universal runners 4 again.

See also Fig. 4 and Fig. 5, the body 6 of desire boring places the utility model below, and can be with each clamping block 3 of its bottom, be connected to pipe shaft, simultaneously, with it fixedly behind the serobila 5 ring bodys 6, the fixing chain hole, open end of serobila 5 is gone here and there behind above-mentioned connecting screw rod 45, and can be screwed into locking to bring nut 46 together, further screw this again and bring nut 46 together, owing to universal drive shaft pearl 44 can freely be reversed along with body 6 caliber radian sizes, therefore, when bringing fixedly serobila 5 together, can make this fixedly serobila 5 can tightly body 6 be tightly wrapped fixing and not stay the gap, so, because the skene arch of clamping block 3 is pulled, make electric drill 22 many again corrections can aim at the center position that institute's desire is holed, moreover, since its fixedly serobila 5 by its with connecting screw rod 45 be connected and utilization is brought nut 46 together and is screwed tight and bring together, therefore, the effect of feasible fixedly body 6 is quite good, the brill that is got out on the body 6 is as the criterion with central point (line) fully, has good processing quality.

In sum, the utility model body boring servicing unit has good practical function, improves the shortcoming of common structure fully, closes the application important document in utility model patent, proposes patent application in accordance with the law.
