Description

Technical Field

[0001] This utility model relates to the field of lathe tool detection equipment, and in particular to a real-time sensing alarm device for lathe tool wear. Background Technology

[0002] Lathe cutting tools are tools used on lathes for metal cutting. Their main function is to remove material from the workpiece to achieve the required dimensions, shape, and surface finish. Lathe cutting tools will experience wear during use, and severe wear can affect machining quality. Therefore, it is necessary to regularly check the wear level of lathe cutting tools.

[0003] Patent publication number CN216298748U discloses an automatic monitoring and early warning device for tool wear in a CNC lathe tool magazine, belonging to the technical field of tool inspection instruments. It includes a tool magazine body, with a tool holder tube fixedly installed inside. A fixing ring is fixedly installed on the outer wall of the tool holder tube. The initial length of the telescopic rod is equal to that of the spring. An inspection ring is fixedly installed on the left side of the telescopic rod. An acoustic transmitter is fixedly installed on the inner wall of the inspection ring, and a sensor is fixedly installed on the outer wall of the inspection ring. The acoustic transmitter emits one audio signal, and the sensor receives two audio signals. The sensor can calculate the difference between the two audio signals. When the audio difference error is large, the sensor will input a signal to an alarm device through a sensing wire. At this time, the alarm device will sound an alarm. Since the alarm device corresponds one-to-one with the inspection ring, the alarm device can accurately provide early warning of damaged tools.

[0004] However, the acoustic emitter in the aforementioned patent needs to move up and down with the telescopic rod. When the tool is in use, if the acoustic emitter moves to a lower position, it is easy to collide with the workpiece and cause damage. Therefore, it cannot perform real-time detection while the tool is running, and it is not easy to sense and alarm the degree of tool wear in real time during tool use. Utility Model Content

[0023] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model.

[0024] This application designs a real-time sensing and alarm device for lathe tool wear, as shown in the attached document. Figure 1 As shown, it includes a housing 1, a warning light 2, a sound wave transmitter 3, an angle adjustment component 4, and a micro motor 41;

[0025] The housing 1 has a through hole in the center for the knife to pass through. A controller is installed on the side of the housing 1. A warning light 2 is installed on the outside of the controller. A sound wave transmitter 3 is located at the bottom of the housing 1. Both the warning light 2 and the sound wave transmitter 3 are driven by the controller.

[0026] Angle adjustment component 4 is used to adjust the angle of sound wave transmitter 3;

[0027] The micro motor 41 is installed on the outside of the housing 1, and the output shaft of the micro motor 41 passes through the inside of the housing 1 and is fixedly connected to the angle adjustment component 4.

[0028] The housing 1 is installed at the bottom of the lathe tool holder and is fitted over the tool through a through hole. The acoustic transmitter 3 is a PXDAQ24260B high-frequency acoustic transmitter. An acoustic sensor is installed on the outside of the acoustic transmitter 3 to receive the reflected high-frequency acoustic waves and calculate the propagation distance. By gradually changing the angle of the acoustic transmitter 3, the acoustic waves can be sent to the entire position of the tool. When the difference in the propagation distance of the acoustic waves at different times at the same position is large, it means that the tool itself has been worn. At this time, a signal is sent to the warning light 2 to trigger an alarm.

[0029] As attached Figure 2 As shown, the angle adjustment assembly 4 includes a gear 42, a gear disc 43, a threaded sleeve 44, a nut 45, and a connecting rod 46;

[0030] The output shaft of the micro motor 41 extends through the interior of the housing 1, and the gear 42 is fixedly connected to the output shaft of the micro motor 41.

[0031] The gear 43 is fixedly connected to the top of the threaded sleeve 44, and the gear 43 meshes with the gear 42.

[0032] The threaded sleeve 44 is rotatably connected inside the housing 1, and the nut 45 is threadedly connected to the threaded sleeve 44.

[0033] The outer side of the nut 45 is rotatably connected to the second connecting rod 46. A sliding groove is provided at the bottom of the housing 1. The bottom end of the second connecting rod 46 extends through the lower part of the sliding groove, and the second connecting rod 46 is movably connected to the sliding groove.

[0034] As attached Figure 3 As shown, a fixing block 31 is fixedly connected to the bottom of the housing 1. The fixing block 31 is rotatably connected to the sound wave transmitter 3. A connecting rod 32 is fixedly connected to the outer wall of the sound wave transmitter 3. A slider 33 is rotatably connected to the end of the connecting rod 32 away from the sound wave transmitter 3. The slider 33 is rotatably connected to the bottom end of the connecting rod 46. A slide rail 34 is movably connected to the top of the slider 33. The slide rail 34 is fixedly connected to the bottom of the housing 1.

[0035] Working principle: The micro motor 41 drives the gear 42 to rotate, and the gear 42 drives the threaded sleeve 44 to rotate through the gear plate 43. Under the limiting action of the slide groove, the nut 45 moves radially. The nut 45 drives the slider 33 to move through the connecting rod 2 46. The slider 33 drives the connecting rod 1 32 to rotate, and the connecting rod 1 32 drives the sound wave transmitter 3 to rotate, thereby adjusting the angle of the sound wave transmitter 3 so that the sound wave transmitter 3 can be located in place to detect the entire tool. Therefore, real-time detection can be performed when the tool is in use, so that the sound wave can be sent to the entire position of the tool. When the difference in the sound wave propagation distance at the same position at different times is large, that is, the tool itself has been worn at this point, a signal is sent to the warning light 22 to trigger an alarm.

[0036] The above embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.
