Description

Technical Field

[0001] The utility model relates to the technical field of drilling and tapping machines, in particular to a drilling and tapping machine for drilling holes in left and right end covers of a turbine box. Background Art

[0002] A drilling and tapping machine is a piece of mechanical equipment used for metal processing. It is mainly used for operations such as drilling, tapping and countersinking on metal workpieces. It is usually composed of a power head, a workbench, a column, a slide, a control system and other parts. The drilling and tapping machine has the characteristics of high precision, high efficiency and easy operation. It is widely used in machinery manufacturing, aerospace, automobile, mold and other industries.

[0003] The end cover of the turbine box is mostly circular, and the end cover needs to be drilled during processing, so that it is convenient to subsequently install the end cover to the reserved hole on the turbine through bolts and other connecting parts. However, during the drilling process of the existing end cover, it is difficult to rotate the fixed rear end cover. In this way, the position of the end cover cannot be adjusted in time during drilling, and workers need to repeatedly adjust the position of the end cover, which increases the workers' operation steps and has low practicality. Utility Model Content

[0004] The purpose of the utility model is to provide a drilling and tapping machine for drilling holes in the left and right end covers of a turbine box, which can solve the problem that it is difficult to rotate the fixed rear end cover.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a drilling and tapping machine for drilling holes in the left and right end covers of a turbine box, comprising a drilling machine body, a drive motor, and a knob block. The drive motor is provided with an end cover body, and the drive motor is used to drive the end cover body to rotate:

[0006] The bottom of the knob block is fixedly mounted with a mounting screw, which is used to fix the end cover body.

[0007] Preferably, an extension plate is fixedly installed on the processing table of the drilling machine body.

[0008] Preferably, two groups of fixed plates are fixedly installed on the top of the extension plate, fixed transverse plates are fixedly installed on the adjacent side walls of the two groups of fixed plates, sliding transverse plates are slidably installed on the outer walls of the fixed transverse plates, a motor support box is fixedly installed on the top of the sliding transverse plates, a rotating column is rotatably installed on the top of the motor support box, a material receiving box is fixedly installed on the top of the rotating column, a driving motor is fixedly installed on the inner top of the motor support box, and the rotating shaft of the driving motor is fixedly installed on one end of the rotating column.

[0009] Preferably, a fixed sleeve is fixedly installed on the inner bottom of the material receiving box, an annular support block is fixedly installed on the top of the fixed sleeve, and the end cover body is placed on the top of the annular support block.

[0010] Preferably, a hole is provided inside the annular support block for the installation screw to move, and the installation screw passes through the end cover body and the annular support block and extends to the interior of the fixed sleeve and is threadedly installed with the fixed sleeve.

[0011] Preferably, an electric push rod is fixedly mounted on the top of the extension plate, and the free end of the electric push rod is fixedly mounted on one side of the sliding horizontal plate. This arrangement facilitates driving the sliding horizontal plate to move.

[0012] Preferably, a threaded groove matching the mounting screw is provided inside the fixing sleeve, so that the mounting screw is easily connected to the fixing sleeve.

[0013] Compared with the prior art, the beneficial effect of the present invention is that the drilling and tapping machine for drilling holes in the left and right end covers of the turbine box can rotate the end cover body when drilling holes in the end cover body through the setting of the driving motor. In this way, when drilling multiple holes on the end cover body, there is no need for workers to adjust the position of the end cover body, which reduces the workers' operating steps and improves the efficiency of drilling holes in the end cover body. Furthermore, through the setting of the electric push rod, the end cover body can be moved out to below the drill bit on the drilling machine body. In this way, when workers load and unload materials, they can stay away from the drill bit on the drilling machine body, which can avoid the drill bit causing harm to the workers, thereby improving the safety of workers during operation.
