Detailed implementation manners

[0065] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the technical solutions provided by the present invention. However, it will be apparent to those skilled in the art that the technical solutions provided by the present invention may be practiced without one or more of these details.

[0066] It should be noted that the terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms.

[0067] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art.

[0068] As Figures 1 to 7 shown, according to a first aspect of the present invention, a processing platform unit is proposed, including: a bed 110; a vertical wall 120, the vertical wall 120 being connected to the bed 110, and the ratio of the width of the vertical wall 120 to the width of the bed 110 being 0.8 to 1.2; a workbench 130, the workbench 130 being connected to the bed 110; a saddle 140, a first dragging component 121 arranged in a first direction being provided on the vertical wall 120, and the saddle 140 being connected to the first dragging component 121; a processing component 150, a second dragging component 141 arranged in a second direction being provided on the saddle 140, and the processing component 150 being connected to the second dragging component 141.

[0069] The processing platform unit provided by the present invention includes a bed body 110, a vertical wall 120, a workbench 130, a saddle 140, and a processing component 150. The ratio of the width of the vertical wall 120 to the width of the bed body 110 is 0.8 to 1.2. The vertical wall 120 with an integrated structure is used to replace the column and crossbeam in the traditional technology. Moreover, the vertical wall 120 has a relatively large width, which can improve the load-bearing capacity of the vertical wall 120 and reduce the deformation of the vertical wall 120, especially reduce the middle collapse of the vertical wall 120 caused by the lower end being suspended. Based on this, the saddle 140 and the processing component 150 are arranged on the vertical wall 120 with higher strength. A first dragging component 121 is formed on the vertical wall 120, and a second dragging component 141 is formed on the saddle 140. Based on this, the processing component 150 can be driven to move in two directions through the first dragging component 121 and the second dragging component 141. During the workpiece processing, only by moving the workpiece in one direction on the workbench 130, three-dimensional motion dimensions can be achieved between the workpiece and the processing component 150, which is convenient for processing the workpiece. At the same time, more motion structures are transferred to the vertical wall 120, reducing the motion structures on the bed body 110 and the workbench 130, and reducing the probability of deformation or misalignment of the workbench 130, thus ensuring the processing accuracy.

[0070] It can be understood that the ratio of the width of the vertical wall 120 to the width of the bed body 110 is 0.8 to 1.2. With such a setting, it not only avoids the excessive width of the vertical wall 120, but also ensures that the vertical wall 120 has sufficient strength to carry the first dragging component 121 and the second dragging component 141, thus ensuring the transmission accuracy. If the ratio of the width of the vertical wall 120 to the width of the machine body is less than 0.8, the load-bearing strength of the vertical wall 120 may be reduced. If the ratio of the width of the vertical wall 120 to the width of the machine body is greater than 1.2, it may lead to the excessive width of the vertical wall 120, an increase in the weight of the vertical wall 120, and inconvenience in the assembly and placement of the processing platform unit. More preferably, for the convenience of processing and assembly of the processing platform unit, the width of the vertical wall 120 can be equal to the width of the bed body 110.

[0071] As Figure 1 、 Figure 2 and Figure 6 shown, in a feasible implementation manner, the processing platform unit further includes: an adjusting member 160, which is arranged at the connection between the vertical wall 120 and the bed body 110 and is used to adjust the assembly inclination angle of the vertical wall 120 relative to the bed body 110; the adjusting member 160 includes: a key insert 161, which is arranged between the bed body 110 and the vertical wall 120, and the key insert 161 is in a convex shape; a key bar 162, which is arranged between the key insert 161 and the vertical wall 120; wherein, the processing platform unit further includes: a glue filling layer, which fills the gap between the bed body 110 and the vertical wall 120.

[0072] In this technical solution, since the vertical wall 120 needs to fix the first dragging component 121, the assembly accuracy of the vertical wall 120 will affect the movement accuracy of the processing component 150, and the vertical wall 120 will have a relatively large weight. Therefore, it is necessary to improve the assembly accuracy of the vertical wall 120. By arranging the adjusting member 160, the assembly angle between the vertical wall 120 and the bed body 110 can be adjusted to ensure the assembly accuracy of the vertical wall 120. Specifically, the adjusting member 160 includes a key 161 and a strip 162. The key 161 is in a convex shape, and spaces for placing the strips 162 are formed on both sides of the convex key 161. During the assembly process, the key 161 is first set between the bed body 110 and the vertical wall 120, and then the strips 162 are inserted. By adjusting the strips 162, the installation angle between the vertical wall 120 and the bed body 110 can be adjusted. By arranging two strips 162 on both sides of the convex key 161, the adjustment of the assembly angle of the vertical wall 120 can be made more accurate. After the vertical wall 120 is assembled with high precision, glue can be poured between the bed body 110 and the vertical wall 120. After the glue solidifies, a glue injection layer can be formed to fix the vertical wall 120 and the bed body 110, reducing or eliminating the probability of misalignment of the vertical wall 120 relative to the bed body 110.

[0073] As Figures 1 to 4 shown, in a feasible implementation, the vertical wall 120 includes: a wall body 122, the wall body 122 is connected to the bed body 110; a through hole 123, the through hole 123 is opened at one end of the wall body 122 close to the bed body 110; a weight reduction hole 124, the weight reduction hole 124 is opened on the wall body 122; a wire passing space 125, the wire passing space 125 is formed at one end of the wall body 122 facing away from the bed body 110.

[0074] In this technical solution, the structural composition of the vertical wall 120 is further provided. The vertical wall 120 may include a wall body 122, a through hole 123, and a weight reduction hole 124. The through hole 123 is formed at one end of the wall body 122 close to the bed body 110 to facilitate avoiding components on the bed body 110 or fasteners moving on the workbench 130. By setting the weight reduction hole 124, the self-weight of the wall body 122 can be reduced, facilitating the installation of the wall body 122 and reducing costs at the same time. By forming a wire passing space 125 at one end of the wall body 122 facing away from the bed body 110, the layout of the cables of the machine tool is facilitated, and the overall structure of the machine tool can be made more compact.

[0075] As Figures 1 to 5 shown, in a feasible implementation, the processing platform unit further includes: a third dragging component 170, the third dragging component 170 is arranged on the bed body 110 along the third direction, and the workbench 130 is connected to the third dragging component 170; wherein, the directions of the first direction, the second direction, and the third direction are different.

[0076] In this technical solution, the machining platform unit may further include a third dragging component 170. The workbench 130 can move relative to the machine body 110 in the third direction through the third dragging component 170. Combining with the first dragging component 121 on the vertical wall 120 and the second dragging component 141 on the saddle 140, three-dimensional movement of the workpiece relative to the machining component 150 can be achieved, and the workpiece can be machined. Among the driving components in the three directions, two driving components are arranged at the end of the vertical wall 120, and only one third dragging component 170 is arranged at the end of the machine body 110, replacing the cross slide structure in the traditional technology, simplifying the structure of the machine body 110, reducing the load borne by the vertical wall 120, reducing the deformation of the slide, and ensuring the machining accuracy.

[0077] As Figures 1 to 5 shown, in a feasible implementation, the machining platform unit further includes: a cooling component 180, and the cooling component 180 is used to supply coolant to at least one of the machining component 150, the first dragging component 121, the second dragging component 141, and the third dragging component 170.

[0078] In this technical solution, the machining platform unit may further include a cooling component 180. The cooling component 180 can supply coolant to the machining component 150, the first dragging component 121, the second dragging component 141, and the third dragging component 170, which can reduce the temperatures of the machining component 150, the first dragging component 121, the second dragging component 141, and the third dragging component 170. Especially when the machining platform unit is applied to high-intensity and high-frequency machining processes, it can ensure the machining accuracy and improve the service life of the machining platform unit at the same time.

[0079] As Figures 1 to 5 shown, in a feasible implementation, the cooling component 180 includes: a liquid storage chain row 181, the liquid storage chain row 181 is connected to the machine body 110 and is used for accumulating liquid; a first pump body 182, the first pump body 182 is connected to the liquid storage chain row 181; a liquid distribution part 183, the first pump body 182 communicates with the liquid distribution part 183, and a metal pipe is arranged on the liquid distribution part 183, and the metal pipe leads to the machining component 150 and is used for supplying coolant to the machining component 150; a second pump body 184, the second pump body 184 is used for supplying coolant to the machining component; an oil cooler 185, and the oil cooler 185 is used for supplying coolant to the first dragging component 121, the second dragging component 141, and the third dragging component 170.

[0080] In this technical solution, the structural composition of the cooling component 180 is further provided. The cooling component 180 may include a liquid storage chain row 181, a first pump body 182, and a liquid distribution part 183. The liquid storage chain row 181 is used to store the coolant, and the coolant can be liquid water. The first pump body 182 extracts the liquid through the liquid storage chain row 181 and supplies it to the liquid distribution part 183. The liquid distribution part 183 then supplies the liquid to the processing component 150 through a metal pipe. The setting of the metal pipe can withstand higher pressures and can output liquid with a higher pressure through the metal pipe, which is convenient for cleaning the processing component 150, especially for cleaning the processing spindle of the processing component 150, facilitating the removal of the processing fines generated during the processing, especially the fines adhering to the spindle, and further ensuring the processing accuracy. Through the setting of the second pump body 184, coolant can be supplied to the spindle of the processing component 150, ensuring the supply flow rate. In particular, the spindle of the processing component 150 can be sprayed annularly to remove the processing fines.

[0081] It can be understood that the pressure of the liquid supplied by the first pump body 182 is greater than the pressure of the second pump body 184. Combined with the metal pipe of the liquid distribution part 183, it can better remove the processing fines from the spindle of the processing component, especially the fines adhering to the spindle. Specifically, the liquid supplied by the first pump body 182 is used to supply to the atomizing nozzle.

[0082] In this technical solution, the oil cooler 185 supplies coolant to the first driving component 121, the second driving component 141, and the third driving component 170, which can ensure the transmission accuracy.

[0083] In a feasible implementation manner, the processing component 150 includes: a spindle, and the cooling component 180 further includes: an atomizing nozzle and an annular nozzle, and the atomizing nozzle and the annular nozzle are used to spray coolant on the spindle.

[0084] In this technical solution, the structural composition of the cooling component 180 is further provided. The cooling component 180 may include an atomizing nozzle and an annular nozzle. Through the atomizing nozzle, atomized coolant can be sprayed. The atomized coolant contacts the spindle, and the phase change from liquid to gas can be used to clean the spindle, with higher cleaning efficiency. Through the setting of the annular nozzle, coolant can be sprayed on the periphery of the spindle, facilitating the cleaning of the spindle, facilitating the removal of the processing fines attached to the periphery of the spindle, avoiding the entanglement of long curly chips, and further ensuring the processing accuracy.

[0085] Such as Figure 7As shown, in a feasible implementation, the first dragging component 121, the second dragging component 141, and the third dragging component 170 all include a lead screw assembly 190. The lead screw assembly 190 includes: a lead screw body 191, which is a hollow structure; a driving part 192, which is connected to one end of the lead screw body 191; a bearing seat 193, and the lead screw body 191 is connected to the other end of the bearing seat 193. A liquid inlet 1911 is formed at one end of the lead screw body 191 close to the driving part 192, and a liquid outlet 1912 is formed at one end of the lead screw body 191 close to the bearing seat 193. The second pump body 184 is used to supply coolant to the liquid inlet 1911.

[0086] In this technical solution, a method for cooling the first dragging component 121, the second dragging component 141, and the third dragging component 170 is further provided. The structures of the first dragging component 121, the second dragging component 141, and the third dragging component 170 all include a lead screw body 191, a bearing seat 193, and a driving part 192. The lead screw body 191 is a hollow structure. The cooling component 180 supplies coolant through one end of the lead screw body 191 close to the driving part 192, and outputs the coolant through one end of the lead screw body 191 close to the bearing seat 193. Such a setting can improve the cooling efficiency of the lead screw body 191.

[0087] In some examples, the material for preparing the lead screw body 191 includes a polydivinyl tube. Such a setting makes the lead screw body 191 have strong corrosion resistance and a high service life.

[0088] As Figure 7 and Figure 8 shown, in a feasible implementation, the processing platform unit further includes: a first temperature sensor 200, which is arranged at one end of the lead screw assembly 190 close to the driving part 192; a second temperature sensor 210, which is arranged at one end of the lead screw assembly 190 close to the bearing seat 193; a memory that stores a computer program; a controller that executes the computer program. Among them, when the controller executes the computer program, it realizes:

[0089] Step 101: Obtain the detection result of the first temperature sensor as the inlet temperature information.

[0090] Step 102: Obtain the detection result of the second temperature sensor as the outlet temperature information.

[0091] Step 103: Obtain the initial temperature of the coolant in the liquid storage chain row, the target adjustment temperature of the lead screw, and the processing duration information of the process.

[0092] Step 104: Determine the flow rate of the coolant supplied to the lead screw body based on the inlet temperature information, the outlet temperature information, the initial temperature, the target regulated temperature, and the processing duration information of the process.

[0093] In this technical solution, the processing platform unit may further include a first temperature sensor 200 and a second temperature sensor 210. Based on this, the temperature at the inlet and the outlet of the coolant of the lead screw assembly 190 can be obtained. The inlet temperature information and the outlet temperature information can characterize the cooling state of the lead screw assembly 190, facilitating high-precision control of the processing platform unit.

[0094] Taking some scenarios as examples, if the temperature difference between the inlet temperature information and the outlet temperature information is less than the first threshold, it indicates that when the coolant flows through the lead screw assembly 190, the heat exchange amount between the coolant and the lead screw assembly 190 is small. In this case, if the outlet temperature information is lower than the second threshold, it means that the current temperature of the lead screw assembly 190 is relatively low, and the supply flow rate of the coolant can be appropriately reduced to make the temperature of the lead screw assembly 190 approach equilibrium during the entire processing process, which can further improve the driving accuracy. On the contrary, if the outlet temperature information is greater than or equal to the second threshold, it indicates that the cooling component 180 has failed, and the processing platform unit should be repaired or maintained.

[0095] Taking some other scenarios as examples, if the temperature difference between the inlet temperature information and the outlet temperature information is greater than or equal to the first threshold, then further analysis should be performed on the inlet temperature information and the outlet temperature information to determine whether the cooling effect meets the requirements. If the inlet temperature information and the outlet temperature information are relatively high, the supply flow rate of the coolant should be increased.

[0096] In this technical solution, the processing platform unit further includes a memory and a controller. The controller can determine the supply flow rate of the coolant based on the detection results of the first temperature sensor 200 and the second temperature sensor 210. Specifically, the controller can process the inlet temperature information, the outlet temperature information, the initial temperature, the target regulated temperature, and the processing duration information of the process, and then determine the flow rate of the coolant supplied to the lead screw assembly based on these information, making the control of the coolant flow rate more accurate. On the premise of meeting the refrigeration requirements, the temperature of the lead screw assembly 190 is more balanced, and thus the driving of the processing assembly 150 and the driving of the workbench 130 are more accurate, ensuring the processing accuracy.

[0097] In a feasible implementation manner, the steps of determining the flow rate of the coolant supplied to the lead screw assembly based on the inlet temperature information, the outlet temperature information, the initial temperature, the target regulated temperature, and the processing duration information of the process include:

[0098] Adjust the flow rate of the coolant based on the following formula:

[0099]

[0100] Among them, T1 is the inlet temperature information, T2 is the outlet temperature information, T0 is the initial temperature, and T n is the target regulated temperature, t is the processing duration of the process, and t α is the instantaneous processing moment, and q v is the flow rate of the coolant.

[0101] In this technical solution, a specific method for determining the flow rate of the coolant is further provided. Through the determination of the above formula, it is more convenient for the controller to execute the program and quantitatively control the flow rate of the coolant, which can improve the control accuracy. Through the determination of the above formula, in the normal working state, the higher the inlet temperature information, the outlet temperature information, and the initial temperature, the greater the flow rate of the coolant. At the same time, the flow rate of the coolant is also related to the time node of processing. Specifically, the closer to the middle area of the processing duration, the greater the flow rate of the coolant. At the starting and ending stages of processing, the flow rate of the coolant is smaller. This supply method can make the temperature of the entire lead screw assembly approach equilibrium and can make the processing accuracy higher.
