Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and more specifically, to a worktable assembly and a machine tool having the same. Background Technology

[0002] In the field of CNC machine tool machining, the worktable, as an important component of the machine tool, undertakes key functions such as fixing the workpiece and supporting machining operations. However, during long-term machining, the worktable may deform due to the high temperature of the machining environment, which in turn affects the machining accuracy and quality.

[0003] Furthermore, machine tools are typically equipped with rotary tables, which are devices that allow workpieces or cutting tools to rotate and be positioned in multiple directions. They are mainly used in high-precision machining equipment such as CNC machine tools and machining centers. By precisely controlling the angle and position of the rotary table, multi-faceted and multi-angle machining of the workpiece can be achieved. During the rotation of the rotary table, friction occurs between its bearings, gears, and other moving parts. Lubrication of the rotary table is usually performed to reduce friction between these components, extend their service life, and reduce energy consumption.

[0004] However, existing rotary table hydraulic circuits usually require separate piping around or inside the worktable, which not only increases space occupation but may also lead to complex hydraulic circuit layout and high installation and maintenance costs. Utility Model Content

[0005] This utility model provides a workbench assembly and a machine tool having the same, in order to solve the problems of existing workbenches being difficult to heat up and deform easily, and having complex oil circuit layouts.

[0006] According to one aspect of the present invention, a worktable assembly is provided, comprising: a body having a machining surface capable of fixing a workpiece to be machined; a cooling channel disposed within the body capable of cooling the body; and an oil supply channel disposed within the body, wherein the cooling channel and the oil supply channel are independent of each other, and the oil supply channel is interconnected with the drive oil circuit of the turntable.

[0007] Furthermore, the body includes an upper platform and a lower platform, with the upper end face of the upper platform forming a machining surface, and cooling channels and oil supply channels both located between the upper platform and the lower platform.

[0008] Furthermore, the lower end face of the upper platform is provided with a first flow groove, and the upper end face of the lower platform is provided with a second flow groove. The first and second flow grooves cooperate to form a flow channel. The side wall of the main body has multiple connecting ports, all of which are connected to the flow channel. The worktable assembly also includes a baffle, which is set in the flow channel to divide the flow channel into a cooling channel and an oil supply channel.

[0009] Furthermore, the oil supply channels are located at both ends of the body along its length, while the cooling channel is located in the middle of the body.

[0010] Furthermore, the workbench assembly also includes a seal disposed between the upper and lower platforms, the seal being used to seal the outer periphery of the flow channel.

[0011] Furthermore, the workbench assembly also includes a plug, which can be selectively connected to some of the multiple connecting ports, with the remaining connecting ports forming a cooling inlet, a cooling outlet, an oil inlet, and an oil outlet. The cooling inlet and cooling outlet are respectively connected to the cooling channel, and the oil inlet and oil outlet are respectively connected to the oil supply channel.

[0012] Furthermore, the workbench assembly also includes a temperature sensor and a pressure sensor, the temperature sensor being used to detect the fluid temperature in the cooling channel and the pressure sensor being used to detect the fluid pressure in the oil supply channel.

[0013] According to another aspect of the present invention, a processing machine tool is provided, which includes a worktable assembly, a machine body, and a rotary table. The worktable assembly is the worktable assembly provided above. The worktable assembly is disposed on the machine body, and the rotary table is rotatably disposed on the machine body. The oil supply channel of the worktable assembly is connected to the drive oil circuit of the rotary table.

[0014] Furthermore, a positioning structure is provided between the main body of the machine body and the worktable assembly. The positioning structure includes a positioning pin and a positioning hole. The positioning hole is located on the machine body, and the positioning pin is located at the bottom of the main body. The positioning pin and the positioning hole cooperate to position the machine.

[0015] Furthermore, the machine tool also includes a vibration damping structure, which is located between the main body and the machine frame.

[0016] By integrating the machining surface, cooling channel, and oil supply channel into the worktable assembly, the overall space utilization of the machine body is improved. Furthermore, by placing the cooling channel within the machining surface, the cooling channel can dissipate the heat generated during machining, effectively preventing the problem of heat deformation of the machining surface during long-term machining, as is common in existing technologies. Moreover, by placing the cooling channel inside the main body, the effect of simultaneous machining and cooling is effectively achieved, further preventing deformation, hardening, or performance degradation of the workpiece due to high temperatures, ensuring the dimensional accuracy and mechanical properties of the workpiece. The design of integrating the oil supply channel and cooling channel into the main body, compared to the existing layout where the oil supply channel is externally located on the periphery of the main body, effectively saves space and eliminates the need to consider interference between the oil supply channel and the main body during operation, further reducing the complexity of the oil supply pipeline layout.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0044] like Figures 1 to 3 As shown, this utility model embodiment provides a worktable assembly, which includes a body 11, a cooling channel 12, and an oil supply channel 13. The body 11 has a machining surface that can fix the workpiece to be machined. The cooling channel 12 is disposed inside the body 11 and can cool the body 11. The oil supply channel 13 is disposed inside the body 11. The cooling channel 12 and the oil supply channel 13 are independent of each other, and the oil supply channel 13 can be connected to the drive oil circuit of the turntable.

[0045] By integrating the machining surface, cooling channel 12, and oil supply channel 13 into the worktable assembly 10, the overall space utilization of the machine body is improved. Furthermore, by placing the cooling channel 12 within the machining surface, it effectively removes heat generated during machining, preventing the problem of thermal deformation of the machining surface during long-term machining, as is common in existing technologies. Moreover, by placing the cooling channel 12 inside the main body 11, the simultaneous machining and cooling effect is achieved, further preventing deformation, hardening, or performance degradation of the workpiece due to high temperatures, ensuring the dimensional accuracy and mechanical properties of the workpiece. This also further accelerates the production pace, reduces the waiting time for natural cooling, and improves production efficiency. Additionally, it slows down the aging of equipment operating at high temperatures and reduces the ambient temperature, improving the comfort of the working environment. By integrating the oil supply channel 13 and the cooling channel 12 into the main body 11, compared with the existing layout where the oil supply channel 13 is externally located on the periphery of the main body 11, the design effectively saves the space occupied by the main body and avoids excessive oxidation and deformation of the oil supply channel 13 during long-term use, thereby reducing maintenance and repair costs. Furthermore, it eliminates the need to consider interference between the oil supply channel 13 and the main body during operation, further reducing the complexity of the oil supply channel 13 layout.

[0046] Specifically, the main body 11 can be a one-piece structure, with a cooling channel 12 and an oil supply channel 13 formed inside. This arrangement reduces the splicing area around the pipe and improves the sealing effect. The main body 11 can also be divided into two parts. In this embodiment, the main body 11 includes an upper platform 111 and a lower platform 112. The upper end surface of the upper platform 111 forms a machined surface, and the cooling channel 12 and the oil supply channel 13 are both located between the upper platform 111 and the lower platform 112. By dividing the main body 11 into an upper platform 111 and a lower platform 112, this application facilitates the machining of the cooling channel 12 and the oil supply channel 13, further improving the flexibility of the pipe flow layout.

[0047] like Figure 4 As shown, the lower end face of the upper platform 111 is provided with a first flow groove 1111, and the upper end face of the lower platform 112 is provided with a second flow groove 1121. The first flow groove 1111 and the second flow groove 1121 cooperate to form a flow channel. The side wall of the body 11 has multiple connecting ports, all of which are connected to the flow channel. The workbench assembly also includes a baffle 14, which is disposed within the flow channel. Specifically, in this embodiment, the baffle 14 can be a cylindrical sealing column. By disposing of the baffle 14 within the flow channel, the flow channel can be divided into a cooling channel 12 and an oil supply channel 13. The baffle 14 can be single-headed, double-headed, or multi-headed.

[0048] Specifically, in this application, the first flow channel 1111 and the second flow channel 1121 are both multi-row and multi-column. The first flow channel 1111 is arrayed on the upper platform 111, and the second flow channel 1121 is arrayed on the lower platform 112. The baffle 14 is set between the upper platform 111 and the lower platform 112, and is located at the intersection of part of the first flow channel 1111, so as to design the flow direction of the cooling channel 12 and the oil supply channel 13.

[0049] like Figure 4 As shown, specifically in this application, the cooling channel 12 is arranged in an "S" shape within the worktable, and the intersection of the flow channels can be blocked using the baffle 14. The fluid contained within the cooling channel 12 is coolant, which can be water, oil, or other specialized coolant, selected according to the processing technology and machine tool requirements.

[0050] Through the above structure, the main body 11 is divided into an upper platform 111 and a lower platform 112, with a first flow groove 1111 and a second flow groove 1121 set on their respective end faces, forming a comprehensive flow channel inside the main body 11. This layout not only effectively utilizes vertical space but also achieves the separation and integration of functional areas. Furthermore, by designing multiple connecting ports on the side wall of the main body 11 to connect with the flow channel, a multi-path, high-efficiency fluid transmission system is constructed, ensuring that coolant or lubricating oil can be evenly and quickly distributed to the key parts of the equipment, improving the cooling and lubrication effect, extending the service life of the equipment, and also enhancing the stability and safety of the system. Moreover, the design of the baffle 14 divides the flow channel into a cooling channel 12 and an oil supply channel 13, realizing the classified flow of fluids, avoiding the mixing and interference of coolant and lubricating oil during the transmission process, and ensuring the maximum functional purity and efficiency of each.

[0051] like Figures 6 to 8As shown, optionally, the cooling channel 12 can be located at both ends of the body 11, and the oil supply channel 13 can be located in the middle of the body 11, or the oil supply channel 13 can be located at both ends of the body 11, and the cooling channel 12 can be located in the middle of the body 11. In this embodiment, the oil supply channel 13 is located at both ends of the body 11 along the length direction of the body 11, and the cooling channel 12 is located in the middle of the body 11. Through the arrangement of the oil supply channel 13 and the cooling channel 12 in this embodiment, both thermodynamic and mechanical efficiency are optimized. By placing the oil supply channel 13 at both ends of the body 11, compared with single-end oil supply, it is ensured that the lubricating oil or fuel can be evenly distributed to the key parts of the entire mechanical structure, such as bearings and gears, thereby effectively reducing wear and energy loss caused by insufficient lubrication and improving the smoothness and lifespan of mechanical operation. At the same time, the cooling channel 12 located in the middle can more efficiently remove the heat generated by friction in the core area, maintain the temperature of the core parts of the machine within a stable and suitable range, prevent overheating damage, and further ensure the stable operation of the mechanical system. This arrangement not only improves cooling efficiency, but also avoids direct contact and potential contamination between lubricating oil and coolant due to the separation of oil supply channel 13 and cooling channel 12, maintaining the purity and efficiency of each system, thus achieving a significant effect of improving mechanical performance and extending service life as a whole.

[0052] The workbench assembly also includes a seal 15, such as Figure 5 As shown, a sealing element 15 is disposed between the upper platform 111 and the lower platform 112, and the sealing element 15 is used to seal the outer periphery of the flow channel. By providing a sealing element 15 on the outer periphery of the flow channel, when the upper platform 111 and the lower platform 112 are fastened together, the upper and lower joints of the flow channel can be sealed, preventing fluid leakage from the flow channel. In this embodiment, the upper platform 111 and the lower platform 112 can be connected by welding, gluing, or bolting. In this embodiment, a bolting connection is used, with the bolt penetrating downwards from the upper surface of the upper platform 111 to the lower platform 112, thus fixing the upper platform 111 and the lower platform 112. As for the sealing of the bolted connection, existing sealing methods can be used, such as fitting a sealing rubber ring on the end of the bolt, or circumferentially fitting a sealing rubber ring on the inner wall of the threaded hole of the upper platform 111 and the lower platform 112. This application uses a bolted connection, which ensures that the upper platform 111 and the lower platform 112 can be quickly disassembled and assembled, facilitating the adjustment of the internal layout of the flow channel and regular maintenance.

[0053] Specifically, the connection between the seal 15 and the body 11 can be by bolt connection, adhesive bonding, etc. In this embodiment, a groove is provided on the outer periphery of the flow channel, and the seal 15 is embedded in the groove. This arrangement can restrict the position of the seal 15 within the body 11. The material of the seal 15 can be rubber, silicone, or polytetrafluoroethylene. In this embodiment, the seal 15 is made of rubber.

[0054] Furthermore, the seal 15 can be disposed on the upper platform 111 or the lower platform 112, or both the upper platform 111 and the lower platform 112 can be disposed simultaneously. In this embodiment, both the upper platform 111 and the lower platform 112 are provided with seals 15, so that the seals 15 can provide all-round protection for the flow channel, and seal the flow channel to the greatest extent to prevent fluid from leaking out through the flow channel and affecting the equipment body.

[0055] like Figure 9 and Figure 10 As shown, the workbench assembly also includes a plug 16, which can be selectively connected to some of the multiple connecting ports. The remaining connecting ports form a cooling inlet, a cooling outlet, an oil inlet, and an oil outlet. The cooling inlet and cooling outlet are respectively connected to the cooling channel 12, and the oil inlet and oil outlet are respectively connected to the oil supply channel 13. The plug 16 and the connecting port can have a plug-in, snap-fit, or other connection structure. In this embodiment, the plug 16 and the connecting port are threadedly connected. Specifically, the end of the plug 16 is provided with a first thread, and the position of the connecting port is provided with a second thread. The first thread and the second thread are engaged to achieve a mating connection between the plug 16 and the connecting port. Furthermore, in this embodiment, a sealing ring 161 is sleeved on the outside of the plug 16 to increase the sealing performance between the plug 16 and the connecting port when they are mated.

[0056] By designing selectively connectable plugs 16 to close part of the communication ports of the worktable assembly, the layout of the cooling channel 12 and the oil supply channel 13 can be flexibly adjusted. This flexibility allows the equipment to be quickly configured and changed according to different processing needs or environmental conditions, improving the adaptability and work efficiency of the equipment. Furthermore, by precisely controlling the flow paths of coolant and lubricating oil, unnecessary waste is avoided, while also helping to keep the work area clean, reducing maintenance costs and time.

[0057] In this embodiment, the worktable assembly also includes a temperature sensor and a pressure sensor. The temperature sensor is used to detect the fluid temperature in the cooling channel 12, and the pressure sensor is used to detect the fluid pressure in the oil supply channel 13. By monitoring the worktable temperature and oil circuit pressure in real time through detection elements such as temperature sensors and pressure sensors, the coolant flow rate and oil pump speed are automatically adjusted according to the monitoring data, achieving precise control of the worktable temperature and oil circuit system, ensuring that the machine tool operates in the optimal working condition, and improving processing efficiency and quality.

[0058] like Figure 11 As shown, in another embodiment of this application, a machine tool is provided, specifically including a worktable assembly 10, a machine body 20, and a rotary table 30, wherein the worktable assembly 10 is the same as the worktable assembly in the above embodiment. The worktable assembly 10 is disposed on the machine body 20, and the rotary table 30 is rotatably disposed on the machine body 20. The oil supply channel 13 of the worktable assembly 10 is connected to the drive oil circuit of the rotary table 30.

[0059] Specifically, the oil supply channel 13 is equipped with devices such as an oil pump, filter, and pressure sensor to control the flow rate, pressure, and cleanliness of the oil circuit, ensuring the normal operation of the oil circuit system. The connection between the oil supply channel 13 and the turntable 30 adopts a flexible pipeline or rotary joint to adapt to the rotational movement of the turntable 30 and ensure the unobstructed and reliable operation of the oil supply channel 13.

[0060] like Figure 12 As shown, a positioning structure 40 is provided between the machine body 20 and the main body 11 of the worktable assembly 10. The positioning structure 40 includes a positioning pin 41 and a positioning hole 42. The positioning hole 42 is provided on the machine body 20, and the positioning pin 41 is provided at the bottom of the main body 11. The positioning pin 41 and the positioning hole 42 cooperate to position the machine body 20.

[0061] In other embodiments, the positioning structure 40 can also be a connection between a positioning pin and a positioning hole, or a snap-fit ​​connection between a slider and a slide rail. However, in this embodiment, the positioning pin 41 is connected to the positioning hole 42, which improves the alignment efficiency of the positioning pin 41 and the positioning hole 42, simplifies the assembly process, and reduces the reliance on additional adjustment or calibration methods. Furthermore, the positioning pin 41 has a tapered structure, and the inner hole of the positioning hole 42 also has a tapered structure, which further improves the alignment effect.

[0062] like Figure 13 As shown, the machine tool also includes a vibration damping structure 50, which is disposed between the main body 11 and the machine frame 20. Specifically, in this embodiment, the vibration damping structure 50 includes a vibration damping pad 52 and an elastic element 51. The vibration damping pad 52 is sleeved on the outer periphery of the positioning pin 41, and the elastic element 51 is sleeved on the outer periphery of the vibration damping pad 52. One end of the elastic element 51 is connected to the positioning pin 41, and the other end of the elastic element 51 is connected to the positioning hole 42. Specifically, the elastic element 51 can be a disc spring, and the vibration damping pad 52 can be a metal rubber pad. With the above configuration, when the machine tool vibrates during high-speed operation or processing, the elastic element 51 can respond quickly and absorb part of the kinetic energy through its own elastic deformation, transforming the direct impact between the positioning pin 41 and the positioning hole 42 into a flexible impact, effectively avoiding damage to components caused by direct impact. The above structure improves the operating stability of the machine tool and extends the service life of the components.

[0063] This application, through the above structural design, has the following advantages:

[0064] 1. Improve machining accuracy and quality: By setting a cooling channel 12 in the middle of the worktable, the temperature of the worktable during the machining process can be effectively reduced, deformation caused by thermal expansion can be reduced, thereby ensuring the stability of the machining process, improving machining accuracy and quality, and extending the service life of the machine tool.

[0065] 2. Space saving: The oil supply channels 13 are arranged on both sides of the workbench, making full use of the structural space of the workbench and avoiding the large amount of space occupied by the traditional oil circuit layout around the machine tool. This makes the overall layout of the machine tool more compact, saves workshop space, and improves the installation flexibility and adaptability of the machine tool.

[0066] 3. Simplified installation and maintenance of oil supply channel 13: The optimized layout of oil supply channel 13 makes the installation of the rotary table 30 oil circuit more convenient, reducing the bends and intersections of the oil supply channel 13, and lowering the installation difficulty and cost. At the same time, it facilitates the inspection and maintenance of oil supply channel 13, improves the reliability and maintainability of the machine tool, reduces downtime caused by oil supply channel 13 failure, and improves production efficiency.

[0067] 4. Enhance machine tool stability: The reasonable layout of the cooling channel 12 and oil supply channel 13 reduces the impact of factors such as thermal deformation of the worktable and oil circuit vibration on the stability of the machine tool, making the machine tool run more smoothly during processing, reducing the failure rate, improving the safety and reliability of production, and providing a strong guarantee for high-precision and high-efficiency processing.
