DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Examples, such as Figure 1 to Figure 5As shown, a device for identifying the depth of pre-buried holes in a learning table board includes a drilling machine and a hole depth identification module. The drilling machine includes a base 1 that is convenient for drilling holes in a plate. On the one hand, it provides stable support for the establishment of various devices and equipment, and on the other hand, it can also facilitate the stable placement of the plate to be processed to ensure the progress of production and processing. A vertical drilling machine assembly 2 is arranged on the rear side above the base 1, and a horizontal drilling machine assembly 3 is arranged at a side corner of the base 1. The vertical drilling machine assembly 2 is used to complete the hole processing on the plate surface, and the horizontal drilling machine assembly 3 is used to complete the hole processing on the side of the plate, which improves the functionality of the device and equipment and meets different usage requirements. In order to effectively complete the convenient identification and measurement of the depth of the processed hole, the hole depth identification module includes a vertical distance measuring assembly 4 and a horizontal distance measuring assembly 5. The horizontal distance measuring component 5 and the vertical distance measuring component 4 include a first mounting bracket 41, and a laser sensor A42 is arranged below the other end of the first mounting bracket 41. The vertical distance measuring component 4 selects a laser sensor A42 with a measuring speed greater than 450 Hz and a measuring range less than 18 mm, and installs it on the first mounting bracket 41. One end of the first mounting bracket 41 is provided with a first hinge hole 411 for facilitating its connection with the vertical drilling machine component 2. The first hinge hole 411 is hingedly connected to the optical axis A7 of the vertical drilling machine component 2. By rotating the first mounting bracket 41, the sensor fastened on the bracket is rotated to the bottom of the drill bit to detect the hole depth, and the working voltage of the laser sensor A42 is the same as the power supply of the vertical drilling machine component 2, so as to reduce multiple power supply configurations.The horizontal distance measuring component 5 includes a second mounting bracket 51, and a laser sensor B52 is arranged on one side of the geometric center of the second mounting bracket 51. Specifically, the horizontal distance measuring component 5 selects a laser sensor B52 with a measuring speed greater than 250 Hz and a measuring range less than 40 mm. A second hinge hole 511 is arranged at one end of the second mounting bracket 51 for facilitating its connection with the horizontal drilling machine component 3, and a lap hole 512 is arranged at the other end of the second mounting bracket 51, wherein the second hinge hole 511 is hinged to one side optical axis B17 on the horizontal drilling machine component 3, and the lap hole 512 is buckled into the top of the other side optical axis B17. By rotating the second mounting bracket 51, the laser sensor B52 fastened on the second mounting bracket 51 is located in front of the drill bit to detect the hole depth, and can be hinged and rotated. At the same time, the laser The working voltage of sensor B52 is the same as the power supply of horizontal drilling machine component 3 to reduce multiple power supply configurations. To further explain: when identifying the depth of the processed hole, the hole depth identification module is connected to the external control module. First, the processing depth data measured by the distance measuring component is obtained and the average value is recorded as C. Then the drilling machine parameter setting data D is obtained again. The budget formula of C*35%+D*65% is used to determine the hole processing depth. The buried hole depth is determined in this proportion. The main reason is that the distance measuring component accounts for a low proportion, mainly because the measurement error is large, but the speed is fast and simple. The vertical drilling machine component 2A and the horizontal drilling machine component 3B of the drilling machine also have errors according to the parameter setting data, because this parameter setting is mainly the product of the number of turns and the pitch. The drilling machine penetration, motor skipping, less than one turn and other cumulative errors are large;

[0020] In the above process: by setting up the vertical distance measuring component 4 and the horizontal distance measuring component 5, the hole depths at different processing positions of the plate can be measured respectively, thereby improving the functionality of the device, and combining the parameter setting data during the operation of the drilling machine component and the data obtained by the distance measuring component to determine the depth of the embedded hole, thereby solving the problem of uneven perforation or hole depth during existing plate processing, improving the work progress, and meeting the production and processing needs of the factory; the device is reasonably designed, simple in structure, easy to process and can realize accurate drilling of the plate, relatively ensure the consistency of the hole depth, fully guarantee the drilling quality, ensure the plate forming quality, improve the work progress, and effectively meet the use needs.

The drill bit fixture A13 is connected to the nut A12 and is spirally connected to the screw-type drill shaft A11. The specific working principle is: the nut A12 is externally connected to the screw-type drill shaft A11, and the stepper motor A10 rotates through the screw-type drill shaft to drive the nut A12 to rotate, thereby driving the drill bit fixture A13 to descend for drilling; it needs to be further explained that: the screw-type drill shaft A11 and the nut A12 have a matching pitch of less than 0.3mm, that is, one circle of rotation is a descent of 0.3mm, so the hole depth error circle is 0.3mm, and half a circle is 0.15mm.

A stepper motor B22 is arranged on the mounting seat 15, and a screw drill shaft B23 is arranged at the output end of the stepper motor B22, and the other end thereof is connected to the nut B20. Specifically, the specific processing working principle is the same as the working principle of the vertical drilling machine assembly 2, that is, the stepper motor B22 is used to provide driving power, and acts on the screw drill shaft B23 to drive the drill fixture B21 and the drill bit B to move to complete the hole processing. It should be further explained that the matching pitch between the screw drill shaft B23 and the nut B20 is less than 0.8mm, so that the depth of the matching rotation is 0.8mm, so that the hole depth error is 0.8mm for one circle and 0.4mm for half a circle, so as to provide convenient conditions for obtaining relatively accurate processing depth.
