Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing equipment, in particular to a multi-axis drilling machine. Background Art

[0002] A drill press is a machine tool commonly used in the manufacturing industry, specifically designed to drill circular holes in a variety of hard materials. It uses a high-speed rotating drill bit to penetrate the surface of the material, and a controlled feed mechanism is used to precisely adjust the diameter and depth of the hole. There are many drill press designs to suit different working situations, such as smaller benchtop drill presses for light work, and larger, more stable vertical and radial drill presses for heavy industrial applications.

[0003] In the current actual production process, a large number of companies, led by OEM factories, mainly use semi-automatic drilling machines. Compared with fully automatic drilling machines, their advantages are not only that the price is only a fraction of that of fully automatic drilling machines, but also that they only require simple manual labor to complete the drilling of workpieces such as pipes. Unlike fully automatic drilling machines, there is no need to readjust the program of the single-chip microcomputer according to the conditions of the workpiece to be drilled. Therefore, this is also the reason why semi-automatic drilling machines are still widely used.

[0004] However, it is precisely because it requires manual operation that the operator not only needs to stabilize the workpiece, but also needs to ensure that the drill can hit the workpiece accurately. During this process, if the operator operates improperly and fails to remove his hand from under the drill in time, it is very easy to get injured. For most OEM factories, although assembly line operation can be efficient, it will also reduce the operator's attention and ultimately lead to such incidents.

[0005] Therefore, a multi-axis drilling machine is proposed to solve or alleviate the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] A multi-axis drilling machine, such as Figure 1 As shown, it includes a vertically arranged electric slide rail 2, a connecting seat 3 fixedly connected to the slide seat of the electric slide rail 2, a reduction motor 4 vertically fixedly connected to the connecting seat 3, a drill 5 fixedly connected to the output shaft of the reduction motor 4, and a transverse and longitudinal adjustment component located below the drill 5. Support frames 1 are fixedly connected to both sides of the electric slide rail 2. An electromagnet 13 is arranged in the transverse and longitudinal adjustment component. The transverse and longitudinal adjustment component includes a longitudinal rail 6 located below the connecting seat 3 and a transverse rail 7 slidably connected thereto. The electromagnet 13 is fixedly connected to the transverse rail 7. The electromagnet 13 and the electric slide rail 2 are electrically connected to an electric control circuit. The electric control circuit controls the electromagnet 13 to be energized, and the electric slide rail 2 is controlled to work after the electromagnet 13 is energized.

[0024] like Figure 2 As shown, it also includes a button switch 1 8 and a button switch 2 9. The output ends of the button switch 1 8 and the button switch 2 9 are electrically connected to the input end of the electric control circuit. The electric control circuit controls the electromagnet 13 to be energized after responding to the button switch 1 8, and controls the electric slide rail 2 to work after responding to the button switch 1 8 and the button switch 2 9 at the same time.

[0025] The electric control circuit includes a NOT gate circuit 10, a control circuit 11 which is a 555 time base chip, a switch circuit 12 which is a triode switch, a trigger circuit 14 which is an RS trigger, and a controller 15 which is a single chip microcomputer;

[0026] The NOT gate circuit 10 is connected to the button switch 18 and the control circuit 11. The control circuit 11 sends a control signal in response to the button switch 18, and the switch circuit 12 controls the electromagnet 13 to be energized after receiving the control signal. The input end of the trigger circuit 14 is respectively connected to the input end of the control circuit 11 and the button switch 29, the output end of the trigger circuit 14 is connected to the input end of the controller 15, and the output end of the controller 15 is electrically connected to the electric slide 2. The trigger circuit 14 sends a trigger signal to the controller 15 in response to the control signal and the button switch 29. After receiving the trigger signal, the controller 15 controls the electric slide 2 to complete a reciprocating movement.

[0027] The input end of the NOT gate circuit 10 is electrically connected, and the push button switch 1 8 is connected between the input end of the NOT gate circuit 10 and the power supply. The output end of the NOT gate circuit 10 is connected to the 2 pin of the 555 timing chip. The output end of the 555 timing chip, that is, its 3 pin is connected to the base of the transistor switch. The collector of the transistor switch is electrically connected, and its emitter is connected to the electromagnet 13 and then grounded. Similarly, the 3 pin of the 555 timing chip and the output end of the push button switch 2 9 are connected to the S and R pins of the RS trigger. The output end Q pin of the RS trigger is connected to the input end of the single-chip microcomputer. The single-chip microcomputer controls the electric slide 2. Similarly, the other end of the push button switch 2 9 is electrically connected.

[0028] When the utility model is used, the operator only needs to manually adjust the positions of the transverse rail 7 and the longitudinal rail 6 to complete the adjustment of the transverse and longitudinal adjustment components, so that the workpiece to be processed can be placed on the transverse rail 7 and moved to the bottom of the drill 5. Then the operator must press the button switch 18 as a self-reset switch with one hand, so that the button switch 18 always remains in a closed state, so that the NOT gate circuit 10 can input a high-level signal, and under the action of the NOT gate circuit 10, the signal is converted into a low-level signal and given to the 555 time base chip. After the 555 time base chip is triggered, a control signal is sent to the base of the transistor switch, so that the collector and emitter of the transistor switch can maintain a connection, so that the electromagnet 13 The electric slide 2 is powered to generate magnetic force, so that the workpiece to be processed is adsorbed on the transverse rail 7 to prevent it from deviating and affecting the drilling. The operator's other hand needs to press the button switch 2 9 which is a self-resetting switch at the same time, so that the control signal and the high-level signal emitted by the button switch 2 9 are given to the trigger circuit 14, so that the trigger circuit 14 sends a trigger signal to the single-chip microcomputer, and the single-chip microcomputer can control the electric slide rail 2 to drive the connecting seat 3 to complete a reciprocating action. During the whole process, the reduction motor 4 will drive the drill 5 to rotate, so as to drill the workpiece while following the reciprocating connection seat 3, ensuring that the operator's hands are respectively pressed on the button switch 1 8 and the button switch 2 9 to avoid contact with the drill 5 and avoid injury.
