TECHNICAL FIELD

[0001] The utility model relates to the technical field of machine tool processing, specifically a double-spindle machine tool with tool cooling protection. BACKGROUND

[0002] Traditional numerical control lathes usually have only one spindle and one tool rest, and the spindle is generally stationary, which can ensure the accuracy of the lathe, but the tool rest is limited, the processing procedure is limited by the number of tool rests, and it is difficult to expand, another lathe needs to be replaced for processing, the efficiency is low, and each unit cycle only processes one workpiece.

[0003] In related technologies, in order to increase the turning efficiency, some lathes use double spindles and tool rests to realize the processing of two different procedures at the same time, but the existing double-spindle double-tool rest cannot clearly see the tool and the spraying of the cooling liquid during work, and when the cooling liquid flow is unstable, the tool cannot be provided with the best cooling effect, which will affect the service life of the tool and the processing quality, or when the tool is excessively worn, the processing quality and efficiency will be affected.

[0004] Therefore, the prior art needs to be improved. SUMMARY

[0005] In order to make up for the problems of the prior art, the present application provides a double-spindle machine tool with tool cooling protection.

[0006] The utility model solves its technical problem and adopts the following technical scheme:

[0007] A double-spindle machine tool with tool cooling protection, comprising a rack, a tool tower and a cooling liquid spraying module, the tool tower is arranged on the rack, a plurality of groups of tools are arranged on the tool tower, the cooling liquid spraying module is used for spraying the stored cooling liquid to the tools, further comprising an image acquisition module and a control module, the image acquisition module is arranged on the rack, the image acquisition module is used for acquiring the condition of the tools and the state of the cooling liquid spraying module spraying the cooling liquid; the control module is arranged on the rack, the control module is electrically connected with the image acquisition module, and is used for analyzing the image information collected by the image acquisition module.

[0008] Preferably, the control module is electrically connected with the cooling liquid spraying module, and the control module is used for controlling the start and stop of the cooling liquid spraying module.

[0009] Preferably, the rack is provided with an alarm module, and the alarm module is connected with the control module.

[0010] Preferably, the alarm module emits sound and light alarm signals when working.

[0011] Preferably, a demisting module is arranged on the rack, and a blowing pipe is arranged at the air outlet end of the demisting module and arranged for the camera in the image acquisition module, so that the demisting module is used to remove water mist on the camera lens in the image acquisition module.

[0014] In summary, the present application has at least one of the following beneficial technical effects:

[0015] 1. Due to the arrangement of the image acquisition module, when the machine tool works, the cooling liquid spraying module sprays cooling liquid onto the tool, and the image acquisition module acquires the picture of the position of the tool, and the control module analyzes and compares the acquired picture, if the tool is seriously worn or the flow of the sprayed cooling liquid is unstable, the control module sends an electric signal to the alarm module, and the alarm module alarms the staff, so as to find and handle the problems in the work of the machine tool, so as to realize the cooling protection of the tool, and further reduce the use cost of the machine tool.

[0016] 2.

[0022] The technical scheme in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the application.

[0023] The embodiment of the application discloses a double-spindle machine tool with tool cooling protection.

[0024] Reference Figure 1 and Figure 2The double-spindle machine tool with tool cooling protection comprises a rack 1, a tool tower 2 and a cooling liquid spraying module 3. Specifically, two main shafts are arranged on the rack 1 and are arranged in a diagonal manner. Two groups of tool towers 2 are arranged correspondingly, and the two groups of tool towers 2 are arranged on the two main shafts respectively. A three-grasp hydraulic chuck device is arranged at the output end of the main shaft to control the action of the tool tower 2. A plurality of groups of tools 21 are arranged on the tool tower 2 to realize different functions. The cooling liquid spraying module 3 is arranged on the rack 1 and also comprises two groups corresponding to the two main shafts. The cooling liquid spraying module 3 comprises a conveying pipeline, a storage tank, a pump and a spray head. The cooling liquid is sprayed onto the tool 21 through the spray head after being flowed out of the conveying pipeline from the storage tank under the action of the pump. An image acquisition module 4 and a control module (not shown in the figure) are further arranged on the rack 1. The image acquisition module 4 comprises a camera 41. The camera 41 is a high-resolution high-speed industrial camera, so that the camera 41 can work stably in a harsh machining environment. Meanwhile, the position of the camera 41 is arranged at a suitable position of the tool 21 cutting and the water outlet end of the cooling liquid spraying module 3, so as to acquire the picture and video information of the position of the tool 21, and ensure that clear and accurate images are acquired. Meanwhile, in order to ensure that the camera 41 can accurately capture the tool 21 and the cooling liquid spraying, the installation position and angle of the camera 41 are carefully designed and debugged. The camera 41 is fixed on the top of the rack 1 of the machine tool through a mounting bracket. The control module is also arranged on the rack 1 and is electrically connected with the image acquisition module 4. The control module is used for receiving and analyzing the images acquired by the image acquisition module 4. The control module has a high-performance microprocessor and an image processing chip, and has a fast data processing capacity and an image recognition capacity. The function of the control module in analyzing the pictures is the prior art, which will not be described in detail in the embodiment. Meanwhile, the control module can also control the start and stop of the whole machine tool. Therefore, when the machine tool works, the image acquisition module 4 will acquire the images of the tool 21 and the cooling liquid spraying, and transmit the acquired pictures and videos to the control module for comparison and analysis to determine whether the cooling liquid is correctly sprayed onto the tool 21, whether the flow of the cooling liquid is uniform and whether the tool 21 is excessively worn. If the tool 21 is excessively worn, the flow of the cooling liquid is not uniform, or the cooling liquid is not sprayed at the correct position, the control module will issue a signal for warning, so as to find and handle the problems in the working of the machine tool, and make the airport stop working, so that the cooling protection of the tool 21 can be realized, and the use cost of the machine tool can be further reduced.

[0025] Reference Figure 1 and Figure 2In the embodiment, the control module is electrically connected with the cooling liquid spraying module 3, and when the tool 21 is excessively worn, the cooling liquid flows unevenly, and the cooling liquid is not sprayed at the correct position, etc., the control module can directly send a signal to stop the cooling liquid spraying module 3 from working, so as to avoid waste of the cooling liquid, thereby minimizing the cost of the machine tool in use.

[0026] Meanwhile, the alarm module 5 is arranged on the rack 1, and the alarm module 5 is electrically connected with the control module, and the control module can send a signal to the alarm module 5 to warn the workers. Since the working environment of the machine tool is a relatively noisy factory, the workers may not be able to hear the alarm sound in time when the alarm module 5 sends a sound alarm. Therefore, in the embodiment, the alarm module 5 adopts a sound-light combination mode, that is, a high-decibel sound is sent at the same time as a striking color, for example, red, is generated, so as to timely attract the attention of the operator and deal with the problem.

[0027] Referring to Figure 1 and Figure 2 Since the cooling liquid is sprayed on the tool 21 when the machine tool is working, and the tool 21 is in high-speed rotation, the cooling liquid is sprayed everywhere, and the tool 21 generates high temperature when rotating at high speed to atomize the cooling liquid. At this time, part of the sprayed cooling liquid and the mist are on the lens of the camera 41 in the image acquisition module 4, which affects the definition of the pictures collected by the image acquisition module 4. Therefore, the demisting module 6 is further arranged on the rack 1. The air outlet end of the demisting module 6 is provided with a blowing pipe 61, and the pipe opening of the blowing pipe 61 is directed to the camera 41 of the image acquisition module 4. When the demisting module 6 works, the blowing pipe 61 blows air to the mirror surface of the camera 41 under the action of the blowing pipe 61, so as to blow away the water mist on the lens, prevent the cooling liquid mist from condensing on the lens surface, and affect the image acquisition quality.

[0028] In the embodiment, the universal pipe 31 is connected to the water outlet end of the cooling liquid spraying module 3. Since the universal pipe 31 itself can change the posture and always maintain the posture, the universal pipe 31 can be bent and adjusted according to the machining position of different tools 21, so as to adjust the position of the water outlet at will, and make the water outlet of the universal pipe 31 directly face the tool 21.

[0029] Meanwhile, in order to make the image acquisition module 4 applicable to more tools 21 and machining conditions, the mounting bracket is arranged on the top of the rack 1, and the mounting bracket is used for mounting the camera 41. The mounting bracket has an adjusting function, so that the camera 41 slides on the rack 1. The adjusting function of the mounting bracket belongs to the prior art, for example, it is realized by a gear and a rack, a portal frame, etc. In the embodiment, it is not described in detail.

[0030] The implementation principle of the embodiment of the double-spindle machine tool with tool cooling protection is as follows: when the machine tool is machining, the image acquisition module 4 acquires images of the tool 21 through the light and the camera 41, if the tool 21 is excessively worn, deformed or even broken, and the flow of the simultaneous jet is unstable, the control module will make the alarm module 5 simultaneously issue an audible and light alarm signal, so as to improve the staff to solve the problem, thereby realizing the cooling protection of the tool 21, and further reducing the use cost of the machine tool.

[0031] The above are preferred embodiments of the present application, not to limit the protection scope of the present application, therefore: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
