All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0023] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0026] See also Figure 1-Figure 2As shown, the automatic short material detection device for a CNC lathe described in this embodiment includes a feeding mechanism 1 and a detection mechanism 2, the feeding mechanism 1 has a discharge end, the detection mechanism 2 is provided with a movable seat 21 and a detection switch 22, the movable seat 21 is used to be installed on the lathe moving slide to move back and forth with the lathe moving slide, the detection switch 22 is installed on the movable seat 21, and is arranged opposite to the feeding end of the feeding mechanism 1 to move with the movable seat 21, and perform short material detection by contacting the material at the discharge end of the feeding mechanism 1.

[0027] This embodiment has a simple structure and a reasonable design. By adding a detection mechanism 2, after the feeding mechanism 1 feeds the material, the movable seat 21 is used to drive the detection switch 22 to move to the set position. By detecting whether the switch 22 contacts the material, flexible short material detection is achieved.

[0028] During specific use, when the CNC lathe program starts processing, the material is first fed through the feeding mechanism 1, and then the detection mechanism 2 moves to the end face of the material. When the detection switch 22 contacts the material, the signal is sent back, indicating that the material is delivered to the position (no short material), so that the detection mechanism 2 moves back to avoid it, and normal processing can be carried out.

[0029] If the detection switch 22 does not touch the material when detecting the material, it means that the material has not been delivered to the right place, that is, there is a shortage of material. At this time, no signal instruction is fed back to the machine, that is, the machine will pause, and the operator will handle the abnormality before resuming production.

[0030] In this embodiment, the movable base 21 is an X / Z-axis slide mounted on the lathe itself to achieve translational movement.

[0031] In some embodiments, the feeding mechanism 1 is provided with a fixed seat 11, a feeding spindle 12 and a feeding chuck 13, the feeding spindle 12 is arranged on the fixed seat 11, the feeding chuck 13 is arranged at the front end of the feeding spindle 12, and the discharge end is located at the end of the feeding chuck 13 away from the feeding spindle 12.

[0032] The present embodiment specifically shows the structural arrangement of the feeding mechanism 1, which is a conventional result. A feeding chuck 13 is provided to achieve clamping and fixing of the material after it is fed into place.

[0033] In some embodiments, a mounting bracket 3 is provided on the movable seat 21 , and the detection switch 22 is installed on the mounting bracket 3 .

[0034] Specifically, the mounting frame 3 includes a base plate 31 , a support plate 32 and a mounting plate 33 . The base plate 31 is detachably mounted on the movable seat 21 , the support plate 32 is mounted on the base plate 31 , and the mounting plate 33 is detachably mounted on the support plate 32 .

[0035] Specifically, the support plate 32 is provided with a vertical adjustment hole 321 , and the mounting plate 33 is provided with a horizontal adjustment hole 331 , so that the support plate 32 and the mounting plate 33 can be installed in an adjustable relative position through the vertical adjustment hole 321 and the horizontal adjustment hole 331 .

[0036] The structural setting of the mounting frame 3 is specifically shown in this embodiment. Such a setting not only facilitates the installation of the detection switch 22, but also can adjust the height and front and rear positions of the detection switch 22 by adjusting the relative positions of the support plate 32 and the mounting plate 33, so as to be suitable for the detection of different feeding lengths. It has a simple structure, is easy to adjust and use, and is highly practical.

[0037] In some embodiments, the detection switch 22 is configured as a compression-type micro switch.

[0038] Specifically, the signal input port of the compression micro switch is connected to the CNC lathe switch through a signal line.

[0039] In this embodiment, a compression-type micro switch is provided, which can realize pressure contact by contacting the material during detection, thereby triggering a signal, thereby achieving flexible and accurate detection.

Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
