Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping machine technology, specifically to an automatic tool breakage monitoring mechanism for a four-head disc drilling and tapping machine. Background Technology

[0002] A four-head disc drilling and tapping machine is a widely used piece of equipment in the machining field. It features four independent heads, enabling simultaneous drilling and tapping operations at multiple positions or in multiple processes on a workpiece. This design significantly improves machining efficiency; compared to single-head machines, it can complete more machining tasks in the same amount of time. The four heads are typically arranged in a disc shape around the machine's working area, rotating or moving to designated machining positions around the worktable or workpiece. This layout facilitates omnidirectional machining of complex-shaped workpieces, allowing for flexible adjustment of machining angles and positions. During the operation of a four-head disc drilling and tapping machine, the integrity of the cutting tools is crucial for both machining quality and efficiency.

[0003] Based on the above, the inventors have discovered the following problems: Current four-head disc drilling and tapping machines have shortcomings in tool breakage monitoring. They often rely on manual periodic inspections or only discover tool breakage after obvious abnormalities occur during processing. This not only easily leads to the generation of a large number of scraps, reduces production efficiency, and increases production costs, but also, in some high-precision processing scenarios, may damage the workpiece and machine tool due to the failure to detect tool breakage in time, causing more serious losses.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an automatic tool breakage monitoring mechanism for a four-head disc drilling and tapping machine, in order to achieve a more practical purpose. Utility Model Content

They often rely on manual periodic inspections or only discover tool breakage after obvious abnormalities occur during processing. This not only easily leads to the generation of a large number of scraps, reduces production efficiency, and increases production costs, but also, in some high-precision machining scenarios, may damage the workpiece and machine tool due to the failure to detect tool breakage in time, causing more serious losses.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An automatic tool breakage monitoring mechanism for a four-head disc drilling rig includes a head column, a controller, and an alarm.

[0008] Furthermore, the displacement monitoring mechanism includes a side frame, one end of which is equipped with an infrared transmitter, and both sides of the top of one of the slide rails are equipped with infrared receivers.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by setting up infrared transmitters and infrared receivers, the movement and positioning of the movable plate can be realized, which facilitates the monitoring of the cutting tool by the laser rangefinder.

[0010] Furthermore, a protective cover is provided at the top of the slide rail, and the inner two sides of the protective cover are fixedly connected to the first and third sides of the machine head column, respectively.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the protective cover at the top of the slide rail improves the protection of the monitoring agency.

[0012] Furthermore, the side frame is located between the slide rail and the protective cover.

[0013] Furthermore, the cross-section of the slide rail is in the shape of an "I".

[0014] The beneficial effect of adopting the above-mentioned further solution is that by making the cross-section of the slide rail into an "I" shape, the sliding stability of the slide rail is improved.

[0015] Furthermore, the top of the controller and the bottom of the alarm are fixedly connected, and the controller is electrically connected to the alarm, laser rangefinder, infrared transmitter, infrared receiver and electric telescopic pole through wires respectively.

[0016] The beneficial effects of adopting the above-mentioned further solutions are that the device can be controlled through the controller settings, increasing the ease of use of the product, and the abnormal alarm function can be realized through the alarm settings.

[0017] Furthermore, the controller is equipped with a wireless transmission module.

[0018] The advantage of adopting the above-mentioned further solution is that a remote alarm function can be realized by having a wireless transmission module inside the controller.

[0019] Compared with existing technologies, the beneficial effects of this utility model are as follows: This four-head disc drilling and tapping machine uses an automatic tool breakage monitoring mechanism.

A connecting seat is installed at the output end of the electric telescopic rod, enabling electric movement of the movable plate. The infrared transmitter and receiver facilitate the movable plate's positioning and movement, allowing the laser rangefinder to monitor the tool. A protective cover at the top of the slide rail enhances the protection of the monitoring mechanism. The "I"-shaped cross-section of the slide rail improves its sliding stability. The controller ensures equipment controllability and increases ease of use. An alarm provides an abnormal alarm function. The controller's internal wireless transmission module enables remote alarm functionality. This utility model effectively achieves automatic tool breakage monitoring, improves production efficiency, and has high practical value. Attached Figure Description
