These terms are only for the convenience of describing the simplified description of the present application and cannot be understood as a limitation on the present application.

[0049] The machine tool preheating control method provided by the present application is mainly used for adaptive preheating of the machine tool within a certain time period when the machine tool is started, so that the machine tool is more easily to reach a relatively ideal running state adapted to the current environment of the machine tool, which helps to shorten the time of the machine tool running to the relatively ideal running state and is beneficial to guarantee the precision of the machine tool processing.

[0050] Referring to Figure 1 , the flowchart of the machine tool preheating control method provided by the present application in an embodiment, the flowchart only schematically shows part of the control steps of the machine tool, and thus part of the steps can be added or reduced and / or the order of part of the steps can be adjusted according to different application scenarios and environmental conditions.

[0051] As Figure 1 shown, the machine tool preheating control method of the present embodiment can include the following steps:

[0052] S101: Before the machine tool starts to perform the zero reset action, the environmental humidity value and the environmental temperature value are obtained.

[0053] In the present embodiment, the machine tool startup is mainly for the case that the machine tool is started after being stopped for more than 3 hours, and the preset temperature and humidity sensor can be used to obtain the corresponding environmental humidity value and environmental temperature value. The preset temperature and humidity sensor can be a single device to obtain the corresponding environmental humidity value and environmental temperature value, of course, two independent devices can also be used to obtain the corresponding environmental humidity value and environmental temperature value.

[0054] S102: The target temperature interval of each preset temperature control region is determined by using the environmental temperature value and the environmental humidity value.

[0055] In the embodiment, the machine tool comprises a plurality of preset temperature control regions, which are regions where heat is relatively significantly generated during operation and / or in a certain state of the machine tool. Specifically, the preset temperature control regions can comprise a spindle temperature control region, a rail temperature control region, and / or a rotary table temperature control region. The rail temperature control region can comprise a linear rail or a hard rail region, a linear drive pair, the linear rail or the hard rail region can comprise X, Y, and Z axis rails, and the linear drive pair can comprise a hollow lead screw and a linear motor. The hard rail of the hard rail region is provided with a liquid medium channel, and the hard rail and the hollow lead screw correspond to different target temperature intervals. Here, the spindle temperature control region, the rail temperature control region, and / or the rotary table temperature control region are relatively generalized temperature control regions, each of which further comprises a plurality of components, each of which can correspond to a temperature control region. Therefore, when determining the target temperature interval of the relatively generalized temperature control region, the lowest corresponding target temperature interval of each component contained therein can be used.

[0056] In the embodiment, the determination of the target temperature interval of each preset temperature control region based on the ambient temperature value and the ambient humidity value can specifically comprise:

[0057] The target temperature interval is obtained from the preset temperature and humidity control table corresponding to the preset temperature control region according to the ambient temperature value and the ambient humidity value. That is, each preset temperature control region corresponds to a preset temperature and humidity control table. The preset temperature and humidity control table establishes an association between temperature values, humidity values, and target temperature intervals. The table obtains the target value of preheating based on different humidity under different temperature scenarios. The table can be stored in a preset database for the machine tool system to query, or the corresponding target temperature interval can be manually set by a person according to the table. Hereinafter, the specific value x in the target temperature interval is used for representation, as shown in Table 1:

[0058]

[0059]

[0060] Table 1

[0061] More specifically, in combination with Table 1, first, the ambient temperature value is determined to belong to a temperature interval, and then the humidity range of the corresponding ambient humidity value is determined according to the temperature interval to determine the target temperature interval.

[0062] It can be understood that the target temperature interval is a temperature value that is determined to be better or best in the running state based on the same or different materials of the preset temperature control region under different humidity and temperature environments.

[0063] S103: control the preset temperature control valve group to respectively deliver liquid medium for temperature adjustment to the preset temperature control area in a preset manner, so as to adjust the temperature of each preset temperature control area to the corresponding target temperature interval.

[0064] In the embodiment, the target temperature interval of the corresponding preset temperature control area is determined by acquiring the ambient temperature and humidity information, and the liquid medium for temperature adjustment is delivered to the corresponding preset temperature control area by the corresponding preset temperature control valve group, so that the relative thermal equilibrium state of the machine tool can be reached after preheating, which helps the machine tool to return to zero to build a machine tool coordinate closer to the thermal equilibrium state of each machine tool coordinate position, thereby helping to ensure the machining precision of the machine tool.

[0065] The preset temperature control valve group includes a plurality of control valves, and one or two control valves can be provided for controlling a preset temperature control area, and a flow rate / flow detection device can also be provided on the corresponding pipeline. In addition, the heat source of the present application can include a plurality of heat sources, and one or two heat sources can provide temperature-adjusted liquid medium at a corresponding temperature for a preheating temperature control area.

[0066] In the embodiment, the preset manner control can include controlling the flow rate, flow rate and / or temperature of the temperature-adjusted liquid medium, so that the corresponding preset temperature control area can adaptively increase the temperature and control the relative flexibility. More specifically:

[0067] First, the temperature value of the preset temperature control area corresponding to the target value is obtained; thereafter, if the difference between the target temperature interval and the temperature value of the corresponding preset temperature control area is greater than a first preset value, the flow of the liquid medium for temperature adjustment is controlled according to the difference between the temperature value of the preset temperature control area and the target temperature interval, and the temperature value of the liquid medium for temperature adjustment is a first temperature value.

[0068] If the difference between the target temperature interval and the temperature value of the corresponding preset temperature control area is greater than a second preset value, the liquid medium for temperature adjustment outputting a second temperature value is controlled according to the difference between the temperature value of the preset temperature control area and the target temperature interval, the first preset value is less than the second preset value, and the first temperature value is less than the second temperature value.

[0069] In addition, each of the preset temperature control areas can include a plurality of sub-areas, and at this time, the target temperature interval of the preset temperature control area is the lowest required temperature value in the plurality of sub-areas.

[0070] In the embodiment, corresponding to the foregoing, when the track temperature control region comprises a hollow screw rod, the preset temperature control valve group is controlled in a preset manner to deliver the liquid medium for temperature adjustment to the preset temperature control region. In the embodiment, the preset temperature control valve group is controlled in a manner of controlling the flow rate in the hollow screw rod and the temperature of the liquid medium to deliver the liquid medium for temperature adjustment to each hollow screw rod (in the case of multiple hollow screw rods) so that the temperature of the hollow screw rod is adjusted to the target temperature interval of the hollow screw rod.

[0071] In another specific application, the hard track with a liquid medium channel needs to be preheated. In this case, the same as the hollow track, the description is omitted.

[0072] Referring to Figure 2 The flowchart of the machine tool preheating control method provided by the application in another embodiment is shown. Compared with the foregoing embodiment, the machine tool in the foregoing embodiment is further prompted by outputting information in the embodiment. Similarly, the flowchart only shows part of the control steps of the machine tool, and thus part of the steps can be added or removed and / or the order of part of the steps can be adjusted according to different application scenarios and environmental conditions.

[0073] S201: Before the machine tool starts to perform the zero reset action, the preset temperature and humidity sensor is used to obtain the ambient temperature value and the ambient humidity value.

[0074] S202: The target temperature interval of each preset temperature control region is determined by using the ambient temperature value and the ambient humidity value.

[0075] S203: The preset temperature control valve group is controlled in a preset manner to deliver the liquid medium for temperature adjustment to the preset temperature control region.

[0076] S204: The temperature difference between the liquid inlet end and the liquid outlet end of each preset temperature control region is obtained.

[0077] S205: If the temperature difference is less than a temperature threshold value, it is determined that the temperature value of the corresponding preset temperature control region is adjusted to the corresponding target temperature interval. Here, the temperature threshold value is preferably as small as possible, but can be determined based on the machining parameters such as the structure, shape and machining method of the workpiece, or can be automatically or manually set based on the machining requirements.

[0078] S206: Information is outputted for prompting.

[0079] In the embodiment, based on the foregoing embodiment, the information prompting manner is used to timely inform the worker, so that the worker can timely control the machine tool in a suitable use state to perform the zero reset action and control the machining, and the operation experience of the worker is improved.

[0080] It can be understood that during each time the machine tool preheating control is performed, the corresponding ambient temperature value, ambient humidity value and actual time spent in this preheating control can also be recorded to form a historical record. Thus in an embodiment, the preheating pipeline or the corresponding preset temperature control area can also be checked by the following steps to find potential adverse effects in time, specifically:

[0081] (1) Obtain the actual time for this time for each of the preset temperature control areas to adjust the temperature to the corresponding target temperature interval.

[0082] (2) Compare the corresponding actual time with the reference time for the corresponding preset temperature control area to adjust the temperature to the same target temperature interval under the same ambient temperature value and the same ambient humidity value in the historical record.

[0083] (3) If the difference between the corresponding actual time and the corresponding reference time is greater than the preset reference time, output a check prompt information.

[0084] The output information prompt can output sound and / or light flash prompts, and can also display the corresponding prompts on the corresponding display panel for the worker to know that the current machine tool has adjusted the temperature of each preset temperature control area to a relatively appropriate state.

[0085] In addition, the time length consumed for adjusting the temperature to the corresponding target temperature interval under the same ambient temperature value and the same ambient humidity value in the historical record can also be displayed as an estimated time length on the corresponding display panel for the worker to refer to.
