Description

Technical Field

[0001] This utility model relates to the field of milling cutter auxiliary equipment technology, and more specifically to a milling cutter tool setting device. Background Technology

[0002] In the field of machining, the milling cutter alignment operation (i.e., adjusting the coincidence of the milling cutter axis with the machining datum) must be completed before milling, which is a crucial step to ensure machining accuracy. Currently, the commonly used milling cutter alignment methods in the industry have the following problems:

[0003] (1) Workers need to put their head or upper body into the milling machine and observe the relative position of the milling cutter and the reference part with the naked eye. During the debugging process, metal chips may remain inside the machining cavity, and the milling cutter is in a high-speed rotating preparation state, which can easily lead to safety accidents such as flying chips causing scratches and accidental contact of the cutter head with limbs.

[0004] (2) Workers need to repeatedly adjust the alignment by inserting their eyes into the machine, withdrawing from the machine, and then inserting their eyes again. Each alignment operation takes a long time and is affected by visual angle deviation, making it difficult to control the alignment accuracy stably.

[0005] (3) For milling machine machining cavities with narrow spaces (such as small precision milling machines), workers cannot put their heads in and can only observe indirectly by holding a flashlight, which further reduces the accuracy of centering and the convenience of operation.

[0006] In the existing technology, although some CNC machine tools use laser tool setters, the equipment cost is as high as tens of thousands of yuan, and it needs to be deeply adapted to the CNC system of the machine tool, so it cannot be popularized on traditional ordinary milling machines; while simple tool setters (such as tool setters) can only help determine the tool length and cannot solve the problem of centering position adjustment.

[0012] The signal transmission module is located inside the camera body; the camera body integrates a high-definition camera, and the high-definition camera is electrically connected to the signal transmission module.

[0013] The external display terminal and the signal transmission module are connected wirelessly.

[0014] Furthermore, the damping joint includes a first link, a second link, and a damping rotation shaft; the first link is rotatably connected to the second link via the damping rotation shaft; the first link is fixed on a circular strong magnetic base, and the second link is connected to the camera body; an adjustment knob is provided on the damping rotation shaft.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] To make the objectives, solutions, and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0031] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to implement the present invention. In other embodiments, well-known structures, circuits, materials, or methods are not specifically described in order to avoid obscuring the present invention.

[0032] The following is in conjunction with the appendix of this utility model. Figures 1-6 The embodiments of this utility model will be described in detail below.

[0033] Example 1:

[0034] Reference Figure 1 and Figure 2 As shown, this embodiment provides a milling cutter tool setting device, including:

[0035] The system includes a camera assembly, a signal transmission module 5, and an external display terminal 3. The camera assembly comprises a camera body 1 and a circular strong magnet base 2; the camera body 1 is connected to the circular strong magnet base 2 via a damping joint 6.

[0036] Reference Figure 3 As shown, the signal transmission module 5 is located inside the camera body 1; the camera body 1 integrates a high-definition camera 4, which is electrically connected to the signal transmission module 5. The high-definition camera 4 is used to capture images of the milling cutter position and transmits them in real time to the external display terminal 3 via the signal transmission module 5. The bottom of the camera body 1 is connected to one end of the damping joint 6. The connection method can be welding, bolt fixing, etc., depending on the actual situation. This embodiment does not limit the connection method.

[0037] The external display terminal 3 is wirelessly connected to the signal transmission module 5, receives signals from the signal transmission module 5 in real time, and displays the milling cutter position image.

[0038] The external display terminal 3 can be a high-definition touch screen, which makes it easy for workers to clearly observe the deviation between the milling cutter and the reference part and determine the adjustment direction.

[0039] In some embodiments, the circular strong magnetic base 2 is made of neodymium iron boron, and the attractive force of the circular strong magnetic base 2 is ≥50N. Alternatively, a strip of permanent magnet or constant magnet can be placed inside the cylindrical circular strong magnetic base 2 to provide magnetic attraction. The specific configuration can be selected based on the actual processing scenario.

[0040] In this embodiment, refer to Figure 4 As shown, the damping joint 6 includes a first connecting rod 601, a second connecting rod 602, and a damping rotation shaft 603; the first connecting rod 601 is rotatably connected to the second connecting rod 602 via the damping rotation shaft 603; the first connecting rod 601 is fixed on the circular strong magnetic base 2, and the second connecting rod 602 is connected to the camera body 1; an adjustment knob 604 is provided on the damping rotation shaft 603. Specifically, the damping joint 6 of this embodiment is designed and implemented with reference to existing damping joint 6 structures, such as patent documents with publication numbers CN113124041A and CN220101792U, which will not be described in detail here.

[0041] In this embodiment, the first link 601 of the damping joint 6 is fixed to the circular strong magnetic base 2 by bolts, and one end of the second link 602 is connected to the camera body 1. When it is necessary to adjust the pitch angle of the camera body 1, the damping of the damping rotation shaft 603 is reduced by adjusting the knob 604, so that the second link 602 can swing. When the appropriate angle is adjusted, the damping of the damping rotation shaft 603 can be increased by adjusting the knob 604, so that the high-definition camera 4 integrated in the camera body 1 is aligned with the centering area of ​​the milling cutter and the reference part, thereby realizing the angle adjustment of the camera body 1. This method does not require repeated disassembly and adjustment of the position of the camera body 1, thus meeting the multi-directional observation requirements under complex working conditions, adapting to the installation position of different milling machine machining cavities, and improving the tool setting efficiency of the milling cutter.

[0042] The first link 601 and the second link 602 are both hollow structures, and their interiors can be used for wiring. By setting corresponding through holes on the rotating shaft, the power cable connecting the high-definition camera 4 can be electrically connected to components such as the power module 7 from inside the damping joint 6.

[0043] In this embodiment, refer to Figure 5 As shown, the circular strong magnetic base 2 has a hollow internal structure, housing a power module 7. A power supply interface 8 is located on the side of the circular strong magnetic base 2. The power module 7 is electrically connected to the high-definition camera 4, the signal transmission module 5, and the power supply interface 8. The power supply interface 8 is electrically connected to the high-definition camera 4 and the signal transmission module 5.

[0044] In this embodiment, the device employs a dual-mode power supply: it can be powered via the built-in power module 7 or by connecting to an external power source through the power interface 8. The power module 7 can utilize a high-capacity lithium battery. The power interface 8 supports an external DC 12V industrial power supply to meet the requirements of long-term continuous operation, and can also charge the lithium battery.

[0045] In some other embodiments of this utility model, since the circular strong magnetic base 2 generates a magnetic field that may affect the charging and discharging performance of the lithium battery, a magnetic shielding material (such as a shielding mesh) is used to wrap the battery compartment to prevent the magnetic field of the circular strong magnetic base 2 from affecting the charging and discharging process of the lithium battery.

[0046] In this embodiment, the signal transmission module 5 specifically adopts a Bluetooth communication module or a WiFi communication module (transmission distance ≥ 5m, delay ≤ 100ms). The signal transmission module 5 is integrated into the camera body 1 and transmits the acquired milling cutter position image to the external display terminal 3 in real time, which can ensure that the worker can observe the alignment status synchronously outside the milling machine.

[0047] In this embodiment, the operation procedure for centering the milling cutter using the milling cutter setting device provided in this embodiment is as follows:

[0048] The milling cutter centering operation procedure is as follows:

[0049] Device installation: The worker does not need to reach into the milling machine. He only needs to hold the camera assembly and attach it to the inner wall of the milling machine's machining cavity (or the reference part bracket) through the circular strong magnetic base 2. Rotate the camera angle to align the lens with the centering area of ​​the milling cutter and the reference part.

[0050] Image acquisition: The high-definition camera 4 and the external display terminal 3 are turned on. The camera acquires images of the relative position of the milling cutter blade and the reference piece in real time, and sends them to the external display terminal 3 via the signal transmission module 5.

[0051] Centering adjustment: The worker observes the image displayed on the external display terminal 3 outside the milling machine and gradually adjusts the position of the milling cutter by operating the machine tool;

[0052] Device disassembly: After centering, turn off the equipment, and use the handheld camera component to overcome the magnetic attraction to remove it from the inner wall of the milling machine for storage.

[0053] The milling cutter setting device provided in this embodiment has the following technical advantages:

[0054] (1) Safety is greatly improved: It completely avoids workers' heads or limbs from entering the milling machine's machining cavity, eliminating accidents such as flying chips scratching or accidentally touching the cutting head from the root, and complies with the safety specifications for machining.

[0055] (2) Efficiency improvement: The centering time can be shortened to 3-8 minutes to meet processing requirements;

[0056] (3) High versatility: Through magnetic installation, there is no need to modify the milling machine by drilling, welding or other means. It can be adapted to most traditional ordinary milling machines and the installation and disassembly are quick.

[0057] (4) Cost controllable: The material cost of the whole set of equipment is low, far lower than that of laser tool setting instrument (ten thousand yuan level), which makes it easy for small and medium-sized enterprises to popularize and apply.

[0058] Example 2:

[0059] In the above embodiment 1, since the circular strong magnetic base 2 is attached to the milling cutter processing machine tool by magnetic attraction, its own magnetic field may interfere with the image acquisition of the high-definition camera 4 in the camera body 1.

[0060] Therefore, in this embodiment, a layer of brass magnetic shielding sheet is placed on the surface of the circular strong magnetic base 2 to avoid magnetic field interference with the camera's electronic components, so that the high-definition camera 4 can stably and clearly capture the milling cutter position image and improve the accuracy of tool setting.

[0061] Example 3:

[0062] In the above embodiment 1, when the high-definition camera 4 captures the image of the milling cutter, the camera itself may be affected by metal shavings or coolant in the processing environment, which may damage the high-definition camera 4 or contaminate the lens, affecting the tool setting efficiency.

[0063] Therefore, refer to Figure 6 As shown, this embodiment includes a removable dust cover 9 on the camera body 1 to prevent metal shavings and coolant from contaminating the lens. The dust cover is fixed to the camera body 1 using a threaded nesting structure. Specifically, the inner edge of the removable dust cover 9 has an internal thread with an inner diameter matching the outer diameter of the camera body 1, and the outer side of the camera body 1 has an external thread matching the internal thread. The removable dust cover 9 is fixed to the camera body 1 through the engagement of the internal and external threads.

[0064] When installing the removable dust cover 9, screw the removable dust cover 9 axially into the camera housing, and achieve a tight fixation through the friction generated by the thread engagement.

[0065] In this embodiment, considering the complex internal structure of the machine tool in the milling environment, where the light source is easily blocked, creating shadow areas, therefore, referring to... Figure 6 As shown, in this embodiment, an LED fill light 10 is also provided on the camera body 1. Figure 6 The image shows four LED supplementary lights, which are used to supplement the lighting for tool setting, provide uniform and stable illumination, ensure clear imaging, and ensure that operators or inspection equipment can clearly observe the relative positional relationship between the milling cutter, the workpiece, and the reference surface, thereby improving tool setting accuracy and efficiency.

[0066] Among them, the LED fill light 10 can be an LED soft light, which provides a softer illumination. Multiple LED soft lights can be set around the high-definition camera 4 to improve the lighting environment during the tool setting process.

[0067] In addition, adding a distance sensor (such as an infrared ranging module) to the camera assembly can be considered to measure the distance between the milling cutter and the lens in real time, automatically adjust the camera focal length, and further improve image clarity.

[0068] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
