Description

Drilling structure that can change the construction angle

technical field

The invention relates to an electric drill auxiliary structure, in particular to a drilling structure capable of changing the construction angle.

Background technique

When carrying out some constructions that require drilling, the hand electric drill is an essential construction tool. However, in some special areas (narrow or high altitude), due to the limitation of the angle, ordinary electric drills cannot complete the drilling construction with angles, resulting in some work cannot be completed, affecting the quality and progress of the project. At present, when drilling at such a special position or angle, a bendable drill bit is used, which can change the angle of the drill bit and output torque, but this drill bit can only rotate 90 degrees, and has a large Due to the limitations of the construction, it cannot fully meet the construction requirements, and its price is very expensive. Therefore need a kind of novel drill structure that can solve the above-mentioned problem now.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art, and propose a drilling structure with simple structure, ingenious design, and the ability to change the torque output angle within a certain range.

The technical solution of the present invention is: a drilling structure that can change the construction angle, including a drill bit 1, which is characterized in that: the drill bit 1 is connected with the inner ring of the one-way thrust bearing 2, and the outer ring of the one-way thrust bearing 2 The ring is connected to the end of the first square tube 3 with a square section, the other end of the first square tube 3 is sleeved with the second square tube 4, and the two contacts between the first square tube 3 and the second square tube 4 Rotating shafts 5 are respectively arranged on the surface, and screw rods 6 are respectively hinged on the opposite sides of the first square tube 3 and the second square tube 4, and the two screw rods 6 are connected by nut columns 7, and on the first square tube 3 And the inner cavity of the second square pipe 4 is provided with a universal hinge 8, one end of the universal hinge 8 passes through the one-way thrust bearing 2 and is connected with the drill bit 1, and the other end of the universal hinge 8 is then connected with the output shaft of the electric drill.

Compared with the prior art, the present invention has the following advantages:

This type of structure can change the construction angle of the drilling structure, its structure is simple, the design is ingenious, it has a certain angle of the traditional electric drill can only output a fixed angle of torque, high cost and other shortcomings, designed a two Mutual hinged square tube structure, and a universal hinge is set in the square tube for torque transmission. At the same time, the combination of nut column and two bolts is used to adjust and fix the processing angle, which can realize the change of processing angle within a certain range. It is suitable for It can be applied to more complex construction conditions for construction operations in some special environments. At the same time, its manufacturing process is simple and its manufacturing cost is low. Therefore, it can be said that it has many advantages and is especially suitable for popularization and application in this field. Its market prospect is very broad.

detailed description

The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. As shown in Figure 1 and Figure 2: a drilling structure that can change the construction angle, including a drill bit 1, the tail end of the drill bit 1 is connected with the inner ring of the one-way thrust bearing 2, and the outer ring of the one-way thrust bearing 2 is Fixedly arranged at the end of the first square pipe 3, the other end of the first square pipe 3 is sleeved with the second square pipe 4, and the two contact surfaces of the first square pipe 3 and the second square pipe 4 are respectively arranged There is a rotating shaft 5. This structure is mainly to prevent the rotating shaft 5 from obstructing the movement of the universal hinge 8; on the opposite side of the first square tube 3 and the second square tube 4, there are respectively hinged screw rods 6, and the two screw rods 6 They are connected by a nut column 7, that is, the two ends of the nut column 7 are threadedly connected with the two screw rods 6 respectively; a universal hinge 8 is also arranged inside the first square tube 3 and the second square tube 4, and this universal One end of the hinge 8 is connected to the drill bit 1 through the one-way thrust bearing 2, and the other end of the universal hinge 8 is connected to the output shaft of the electric drill; in order to allow relative rotation between the first square tube 3 and the second square tube 4 , in the first square pipe 3 or the second square pipe 4 at least one square pipe wall in the opposite direction needs to be removed.

The working process of the drilling structure that can change the construction angle in the embodiment of the present invention is as follows: when drilling in some special areas, the drilling structure of this structure is installed on the hand electric drill, and rotated according to the required angle The nut column 7, with the rotation of the nut column 7, the relative position between the nut column 7 and the two screw rods 6 changes, thereby driving the two hinged first square tubes 3 and the second square tube 4 to rotate relative to each other , after adjusting to the required angle, stop rotating the nut column 7, the first square tube 3 and the second square tube 4 are fixed and fixed due to the existence angle of the nut column 7, start the motor of the hand drill, and let the universal hinge 8 The drill bit 1 is driven to rotate to realize the drilling operation, and the one-way thrust bearing 2 connected with the drill bit 1 can bear part of the load.
