Technical Field

[0001] The utility model belongs to the technical field of building steel structures, and particularly relates to a drilling positioning device for building steel structures. Background Technique

[0002] During the construction of buildings, steel structures are needed. A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to rust, and generally steel structures need to be derusted, galvanized or painted, and need to be maintained regularly.

[0003] After the building steel structure is assembled, in order to carry out connection, it is necessary to drill holes in the steel structure. The existing drilling method is that workers hold a drilling machine to perform drilling operations, and there is no effective drilling positioning device. The hand-held operation is inconvenient, the efficiency is low, and the problem of inaccurate positioning and reduced accuracy is likely to occur. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drilling positioning device for building steel structures, so as to solve the problems in the above-mentioned background technique that the existing drilling method is that workers hold a drilling machine to perform drilling operations, and there is no effective drilling positioning device, the hand-held operation is inconvenient, the efficiency is low, and the problem of inaccurate positioning and reduced accuracy is likely to occur.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A drilling positioning device for building steel structures, including a base plate, on which there are two clamping plates one arranged one above the other. The clamping plate one at the upper position is fixed on the base plate, and the clamping plate one at the lower position is movably arranged on the base plate. A clamping plate two is movably arranged on the clamping plate one. A bolt is threadedly installed on the side surface of the clamping plate one, and the tail end of the bolt is in contact with the side surface of the clamping plate two. The base plate has a cavity inside, and an installation shell is movably arranged in the cavity. A fixed seat is fixedly installed on the side surface of the installation shell, and a locking rod is slidably installed on the fixed seat. One end of the locking rod is fixedly installed with an operation plate. A number of locking grooves for inserting the locking rod are opened on the side surface of the base plate. An installation plate is arranged inside the installation shell. A drilling machine main body is fixedly installed on the side surface of the installation plate facing the opening of the installation shell. A rotating shaft is rotatably installed on the side surface of the installation plate away from the opening of the installation shell. A threaded rod is threadedly installed on the side surface of the installation shell, one end of the threaded rod is fixedly connected with the rotating shaft, and the other end of the threaded rod is fixedly installed with a knob.

[0006] With the above solution, by arranging the first clamping plate and the second clamping plate to cooperate with the substrate and the installation shell, using two first clamping plates, one on top and the other at the bottom, and one of the first clamping plates being movably arranged, the whole can be clamped on the relatively two sides of the upper and lower parts of the steel structure. By using the substrate to cooperate with the movably arranged second clamping plate, the whole can be further clamped on the relatively two sides of the left and right parts of the steel structure, thereby realizing the installation of the installation shell. By using the threaded rod to cooperate with the drilling machine main body, there is no need to hold the operation for drilling, ensuring good precision of the drilling operation and convenient operation. By arranging the locking rod to cooperate with the installation shell, the installation shell can slide up and down and be locked in position by the locking rod, thereby realizing the drilling operation at different positions and improving the universality.

[0007] In the above solution, it should be noted that the drilling machine main body is electrically connected to an external power supply.

[0008] As a preferred implementation manner, a trapezoidal block is fixed to the inner wall of the movably arranged first clamping plate. A trapezoidal groove for the trapezoidal block to slide is formed on the side surface of the substrate, and a first spring is fixedly installed on the inner wall of the trapezoidal groove. The first spring is fixedly connected to the trapezoidal block.

[0009] With the above solution, by using the trapezoidal block to cooperate with the trapezoidal groove, the convenient sliding of the first clamping plate at the lower position is realized, achieving position adjustment. Moreover, the trapezoidal block and the trapezoidal groove cooperate to achieve a limiting effect, preventing the first clamping plate from sliding off the substrate. When the first clamping plate at the lower part moves downward, the first spring deforms. Therefore, the elasticity of the first spring can play a preliminary clamping effect and provide a quick reset effect.

[0010] As a preferred implementation manner, a plurality of guide rods are fixed to the inner wall of the first clamping plate. A second spring is sleeved outside the guide rods. The second clamping plate is slidably installed on the outer surface of the guide rods.

At the same time, when the bolt is screwed in to drive the movement of the second clamping plate, the second spring will deform. Therefore, when the bolt is screwed out, the elasticity of the second spring can be used to drive the second clamping plate to quickly reset, improving the operation convenience.

[0012] As a preferred implementation manner, a guide strip is fixedly installed on the inner wall of the cavity of the substrate. A guide groove for cooperating with the guide strip is formed on the side surface of the installation shell.

[0013] With the above solution, by using the guide strip to cooperate with the guide groove, the installation shell can slide up and down stably, preventing shaking.

[0014] As a preferred embodiment, a limit ring is sleeved outside the lock rod, the limit ring is located inside the fixed seat, and a third spring is fixedly installed between the limit ring and the fixed seat.

[0015] With the above solution, by using the limit ring in cooperation with the spring, the limit ring can prevent the lock rod from slipping out of the fixed seat when sliding, and the third spring deforms when the lock rod disengages from the lock groove. Therefore, the elastic force of the third spring can be used to quickly drive the lock rod to reset and insert into the lock groove, improving the convenience of the locking operation.

[0016] As a preferred embodiment, a plurality of sliding blocks are fixed to the side surface of the mounting plate, a plurality of sliding grooves are formed in the inner wall of the mounting shell, and the sliding blocks are slidably installed in the inner walls of the sliding grooves.

[0017] With the above solution, by using the sliding blocks in cooperation with the sliding grooves, good movement smoothness of the mounting plate can be achieved.
