DETAILED DESCRIPTION

[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the technical solutions provided by the present invention. However, it is obvious to those skilled in the art that the technical solutions provided by the present invention can be implemented without one or more of these details.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of the features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0024] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete, and to fully convey the concept of these exemplary embodiments to those of ordinary skill in the art.

[0025] like Figures 1 to 7As shown, according to the first aspect of the present invention, a processing platform unit is proposed, including: a bed 110; a vertical wall 120, the vertical wall 120 is connected to the bed 110, and the ratio of the width of the vertical wall 120 to the width of the bed 110 is 0.8 to 1.2; a workbench 130, the workbench 130 is connected to the bed 110; a saddle 140, a first drag component 121 arranged along a first direction is provided on the vertical wall 120, and the saddle 140 is connected to the first drag component 121; a processing component 150, a second drag component 141 arranged along a second direction is provided on the saddle 140, and the processing component 150 is connected to the second drag component 141.

[0026] The processing platform unit provided by the present invention includes a bed 110, a vertical wall 120, a workbench 130, a saddle 140 and a processing assembly 150, wherein the ratio of the width of the vertical wall 120 to the width of the bed 110 is 0.8 to 1.2, and the vertical wall 120 with an integrated structure is used to replace the columns and beams in the traditional technology, and the vertical wall 120 has a larger 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 collapse of the middle part of the vertical wall 120 caused by the lower end of the vertical wall 120 being suspended. Based on this, the saddle 140 and the processing assembly 150 are arranged on the vertical wall 120 with higher strength, and a first drag assembly 121 is formed on the vertical wall 120, and a second drag assembly 141 is formed on the saddle 140. Based on this, the first drag assembly 121 and the second drag assembly 141 can drive the processing assembly 150 to move in two directions. During the workpiece processing, the workpiece only needs to move in one direction on the workbench 130 to achieve three-dimensional movement between the workpiece and the processing assembly 150, which is convenient for processing the workpiece. At the same time, more moving structures are transferred to the vertical wall 120, reducing the moving structures on the bed 110 and the workbench 130, reducing the probability of deformation or dislocation of the workbench 130, and ensuring the processing accuracy.

[0027] It is understandable that the ratio of the width of the vertical wall 120 to the width of the bed 110 is 0.8 to 1.2. This configuration can prevent the width of the vertical wall 120 from being too large, while ensuring that the vertical wall 120 has sufficient strength to carry the first drag assembly 121 and the second drag assembly 141, thereby ensuring 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 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, the width of the vertical wall 120 may be too large, the weight of the vertical wall 120 increases, and it is not convenient to assemble and place the processing platform unit. More preferably, in order to facilitate the processing and assembly of the processing platform unit, the width of the vertical wall 120 can be the same as the width of the bed 110.

[0028] like Figure 1 , Figure 2 and Figure 6 As shown, in a feasible embodiment, the processing platform unit also includes: an adjusting member 160, which is arranged at the connection between the vertical wall 120 and the bed 110, and is used to adjust the assembly inclination angle of the vertical wall 120 relative to the bed 110; the adjusting member 160 includes: an inlay key 161, which is arranged between the bed 110 and the vertical wall 120, and the inlay key 161 is in a convex shape; an inlay strip 162, which is arranged between the inlay key 161 and the vertical wall 120; wherein the processing platform unit also includes: a glue potting layer, which fills the gap between the bed 110 and the vertical wall 120.

[0029] In this technical solution, since the vertical wall 120 needs to fix the first drag assembly 121, the assembly accuracy of the vertical wall 120 will affect the movement accuracy of the processing assembly 150, and the vertical wall 120 will have a large weight, so it is necessary to improve the assembly accuracy of the vertical wall 120. By arranging the adjustment member 160, the assembly angle between the vertical wall 120 and the bed 110 can be adjusted to ensure the assembly accuracy of the vertical wall 120. Specifically, the adjustment member 160 includes a key 161 and a strip 162. The key 161 is in a convex shape. 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 110 and the vertical wall 120, and then the strip 162 is inserted. By adjusting the strip 162, the installation angle of the vertical wall 120 and the bed 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 110 and the vertical wall 120. After the glue solidifies, a glue layer can be formed, which can fix the vertical wall 120 and the bed 110, reducing or eliminating the probability of the vertical wall 120 being misaligned relative to the bed 110.

[0030] like Figures 1 to 4 As shown, in a feasible embodiment, the vertical wall 120 includes: a wall 122, which is connected to the bed 110; a through hole 123, which is opened at one end of the wall 122 close to the bed 110; a weight-reducing hole 124, which is opened on the wall 122; and a through-line space 125, which is formed at one end of the wall 122 away from the bed 110.

[0031] In this technical solution, the structural composition of the vertical wall 120 is further provided. The vertical wall 120 may include a wall 122, a through hole 123 and a weight-reducing hole 124. The through hole 123 is formed at one end of the wall 122 close to the bed 110, so as to facilitate the avoidance of the components on the bed 110 or the parts moving on the workbench 130. The weight-reducing hole 124 can reduce the deadweight of the wall 122, facilitate the installation of the wall 122, and reduce the cost. By forming a wire passing space 125 at one end of the wall 122 away from the bed 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.

[0032] like Figures 1 to 5 As shown, in a feasible embodiment, the processing platform unit also includes: a third drag component 170, the third drag component 170 is arranged on the bed 110 along the third direction, and the workbench 130 is connected to the third drag component 170; wherein the directions of the first direction, the second direction and the third direction are different.

[0033] In this technical solution, the processing platform unit can further include a third drag component 170. The workbench 130 can move in a third direction relative to the bed 110 through the third drag component 170. Combined with the first drag component 121 on the vertical wall 120 and the second drag component 141 on the slide saddle 140, the three-dimensional movement of the workpiece relative to the processing component 150 can be realized, and the workpiece can be processed. 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 drag component 170 is arranged at the end of the bed 110, which replaces the cross slide structure in the traditional technology, simplifies the structure of the bed 110, reduces the load-bearing through the vertical wall 120, reduces the deformation of the slide, and ensures the processing accuracy.

[0034] like Figures 1 to 5 As shown, in a feasible embodiment, the processing platform unit further includes: a cooling component 180, and the cooling component 180 is used to supply cooling liquid to at least one of the processing component 150, the first drag component 121, the second drag component 141 and the third drag component 170.

[0035] In this technical solution, the processing platform unit may further include a cooling component 180, which may supply coolant to the processing component 150, the first drag component 121, the second drag component 141 and the third drag component 170, thereby reducing the temperature of the processing component 150, the first drag component 121, the second drag component 141 and the third drag component 170, especially enabling the processing platform unit to be used in high-intensity, high-frequency processing processes, thereby ensuring processing accuracy and improving the service life of the processing platform unit.

[0036] like Figures 1 to 5 As shown, in a feasible embodiment, the cooling component 180 includes: a liquid storage chain row 181, the liquid storage chain row 181 is connected to the bed 110, and is used to store liquid; a first pump body 182, the first pump body 182 is connected to the liquid storage chain row 181; a liquid separation part 183, the first pump body 182 is connected to the liquid separation part 183, and a metal pipe is provided on the liquid separation part 183, and the metal pipe is connected to the processing component 150, and is used to supply cooling liquid to the processing component 150; a second pump body 184, the second pump body 184 is used to supply cooling liquid to the processing component; an oil cooler 185, the oil cooler 185 is used to supply cooling liquid to the first drag component 121, the second drag component 141 and the third drag component 170.

[0037] 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 181, a first pump body 182 and a liquid separation part 183. The liquid storage chain 181 is used to store coolant, which may be liquid water. The first pump body 182 extracts liquid through the liquid storage chain 181 and supplies it to the liquid separation part 183. The liquid separation part 183 then supplies the liquid to the processing component 150 through a metal pipe. The metal pipe can withstand a higher pressure and output a higher pressure liquid through the metal pipe, which is convenient for cleaning the processing component 150, especially for cleaning the processing spindle of the processing component 150, and for removing the processing chips generated during the processing, especially removing the chips adhered to the spindle, further ensuring the processing accuracy. The second pump body 184 can supply coolant to the spindle of the processing component 150, ensuring the supply flow, especially the spindle of the processing component 150 can be sprayed in an annular manner to remove the processing chips.

[0038] It is understandable that the pressure of the liquid supplied by the first pump body 182 is greater than the pressure of the second pump body 184, and combined with the metal pipe of the liquid separation part 183, it is possible to better remove the machining chips from the spindle of the machining component, especially to remove the chips adhering to the spindle. Specifically, the liquid supplied by the first pump body 182 is used to supply the mist nozzle.

[0039] In this technical solution, the oil cooler 185 supplies cooling liquid to the first drag assembly 121 , the second drag assembly 141 and the third drag assembly 170 , which can ensure transmission accuracy.

[0040] In a feasible implementation, the processing assembly 150 includes: a spindle, and the cooling assembly 180 further includes: a mist nozzle and an annular nozzle, and the mist nozzle and the annular nozzle are used to spray cooling liquid on the spindle.

[0041] In this technical solution, the structural composition of a cooling component 180 is further provided. The cooling component 180 may include a mist nozzle and an annular nozzle. A mist of coolant can be sprayed through the mist nozzle. The mist of coolant contacts the spindle and can utilize the phase change from liquid to gas to clean the spindle, thereby achieving higher cleaning efficiency. Through the arrangement of the annular nozzle, coolant can be sprayed on the periphery of the spindle, thereby facilitating the cleaning of the spindle and removing machining chips attached to the periphery of the spindle, thereby avoiding the entanglement of long chips and further ensuring machining accuracy.

[0042] like Figure 7 As shown, in a feasible embodiment, the first drag component 121, the second drag component 141 and the third drag component 170 all include a screw assembly 190, and the screw assembly 190 includes: a screw body 191, the screw body 191 is a hollow structure; a driving part 192, the driving part 192 is connected to one end of the screw body 191; a bearing seat 193, the 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 screw body 191 close to the driving part 192, and a liquid outlet 1912 is formed at one end of the screw body 191 close to the bearing seat 193, and the second pump body 184 is used to supply cooling liquid to the liquid inlet 1911.

[0043] In this technical solution, a method for cooling the first drag component 121, the second drag component 141 and the third drag component 170 is further provided. The structures of the first drag component 121, the second drag component 141 and the third drag component 170 all include a screw body 191, a bearing seat 193 and a driving part 192. The screw body 191 is a hollow structure. The cooling liquid is supplied through the cooling component 180 through one end of the screw body 191 close to the driving part 192, and the cooling liquid is output through one end of the screw body 191 close to the bearing seat 193. Such an arrangement can improve the cooling efficiency of the screw body 191.

[0044] In some examples, the material used to make the screw body 191 includes a polyethylene tube, which makes the screw body 191 highly corrosion-resistant and has a long service life.

[0045] like Figure 7 and Figure 8 As shown, in a feasible implementation manner, the processing platform unit further includes: a first temperature sensor 200, the first temperature sensor 200 is arranged at one end of the screw assembly 190 close to the driving part 192, a second temperature sensor 210, the second temperature sensor 210 is arranged at one end of the screw assembly 190 close to the bearing seat 193; a memory storing a computer program; a controller executing the computer program; wherein, when the controller executes the computer program, the following is realized: Step 101: Acquire the detection result of the first temperature sensor as inlet temperature information; Step 102: Acquire the detection result of the second temperature sensor as outlet temperature information; Step 103: obtaining the initial temperature of the coolant in the liquid storage chain, the target adjustment temperature of the lead screw, and the processing time information of the process; Step 104: Determine the flow rate of the coolant supplied to the screw body based on the inlet temperature information, the outlet temperature information, the initial temperature, the target adjustment temperature and the processing time information of the process.

[0046] In this technical solution, the processing platform unit may also include a first temperature sensor 200 and a second temperature sensor 210, based on which the temperature at the inlet and outlet of the coolant of the screw assembly 190 can be obtained. The inlet temperature information and the outlet temperature information can characterize the cooling state of the screw assembly 190, thereby facilitating high-precision control of the processing platform unit.

[0047] Taking some scenarios as an example, if the temperature difference between the inlet temperature information and the outlet temperature information is less than the first threshold, it means that when the coolant flows through the screw assembly 190, the heat exchange between the coolant and the 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 screw assembly 190 is low, and the supply flow rate of the coolant can be appropriately reduced to achieve a temperature balance of the screw assembly 190 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 means that the cooling assembly 180 has a fault and the processing platform unit should be repaired or maintained.

[0048] Taking some scenarios as an example, if the temperature difference between the inlet temperature information and the outlet temperature information is greater than or equal to the first threshold, then the inlet temperature information and the outlet temperature information should be further analyzed to determine whether the cooling effect meets the requirements. If the inlet temperature information and the outlet temperature information are high, then the supply flow rate of the coolant should be increased.

[0049] In this technical solution, the processing platform unit also 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 determine the inlet temperature information, the outlet temperature information, the initial temperature, the target adjustment temperature and the processing time information of the process, and then determine the flow rate of the coolant supplied to the screw assembly based on this information, so that the flow rate control of the coolant is more precise. On the premise of meeting the refrigeration requirements, the temperature of the screw assembly 190 is more balanced, and then the drive of the processing assembly 150 and the drive of the workbench 130 are more precise, thereby ensuring the processing accuracy.

[0050] In a feasible implementation, based on the inlet temperature information, the outlet temperature information, the initial temperature, the target adjustment temperature and the processing time information of the process, the step of determining the flow rate of the coolant supplied to the screw assembly includes: Adjust the coolant flow rate based on the following formula:

[0051] Among them, T1 is the inlet temperature information, T2 is the outlet temperature information, T0 is the initial temperature, T n is the target temperature, t is the processing time of the process, t α is the processing instant, q v is the flow rate of the coolant.

[0052] 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 easier for the controller to execute the program and perform quantitative control on the flow rate of the coolant, which can improve the control accuracy. Through the determination of the above formula, under normal working conditions, 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 the processing. Specifically, the closer to the middle area of ​​the processing time, the greater the flow rate of the coolant. At the beginning and end of the processing, the flow rate of the coolant is smaller. This supply method can make the overall temperature of the screw assembly approach equilibrium, and can make the processing accuracy higher.

[0053] like Figures 1 to 8 As shown, according to the second aspect of the present invention, a machine tool structure is proposed, including: a machining platform unit as described in any of the above technical solutions.

[0054] The machine tool structure provided by the present invention includes a processing platform unit as described in any of the above technical solutions.
