Embodiment 1

[0020] see Figure 1-3 , a small drilling machine, comprising a body 1, a workbench 2 is arranged on the upper surface of the body 1, a feed mechanism and a fixture are arranged at intervals on the workbench 2, a workpiece is installed in the fixture, and the feed mechanism includes a fixing seat 7, The fixed seat 7 is fixedly connected to the upper end surface of the workbench 2. The section of the fixed seat 7 is U-shaped. The fixed seat 7 is equipped with a feed screw 9 through a fixed bearing 8. The feed screw 9 is equipped with a feed block 10 , the feed block 10 is connected to the feed screw 9 in transmission, and the upper end side of the feed block 10 is fixedly connected with a tool holder 12, and a cutter 13 is installed in the cutter holder 12, and the cutter 13 is connected with a drilling motor 11 through transmission, and the drilling The motor 11 is located on one side of the tool holder 12 and is fixedly connected with the feed block 10; one end of the feed sc...

Embodiment 2

[0030] In Embodiment 1, the body 1 is placed on the ground and it is inconvenient to move. Therefore, this embodiment is improved on the basis of Embodiment 1. The improvement is: a universal wheel 6 that is easy to move is arranged under the body 1, Save labor when moving the machine tool.

Abstract

The invention discloses a small drilling machine. The small drilling machine comprises a machine body; a workbench is arranged on the upper end face of the machine body; a feeding mechanism and a clamp are arranged on the workbench at intervals; and a workpiece is installed in the clamp. The small drilling machine is simple in operation, is easy to clamp the workpiece and is suitable for being popularized in college engineering training centers. The punching rate of a cutter is controlled through a feeding motor, so that drilling is smoother and more uniform; a sliding mechanism is connected at the lower part of a mounting seat, so that a distance between the workpiece and the cutter can be changed by shaking a handle, and therefore, operation is convenient; a cooling mechanism is arrangedabove the workpiece, so that water can be sprayed out of a spray head to cool the cutter during punching, and therefore, the service life of the cutter can be prolonged; a storage cabinet is arrangedin the machine body, so that operation tools can be stored and are convenient to take; and universal wheels are arranged at the lower part of the machine body, so that an operator can move the machine just by pushing the machine body, and therefore, the labor intensity of the operator is reduced.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a small drilling machine. Background technique [0002] Drilling machine is an indispensable equipment for machinery manufacturing and various repair factories. It uses the rotation of the drill bit as the main movement, and the axial movement of the drill bit is the feed movement to process and punch holes on the workpiece. The drilling machine has a simple structure and relatively low machining accuracy, and can process drilling, reaming, reaming, tapping, countersinking, etc. During the machining process, the drilling machine fixes the workpiece and the tool rotates. At present, domestic colleges and universities majoring in machinery and vehicles often need to carry out engineering training for students to combine textbook knowledge with practice; most of the drilling machines used for practical training in existing colleges and universities are manually operated, whil...
