Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] This embodiment provides a constant temperature controlled machine tool workbench, such as Figure 1 As shown, it includes a workbench body 1 and T-slot inserts 2. Multiple groups of the T-slot inserts 2 are embedded in the workbench body 1. The upper surface of the T-slot inserts 2 is flush with the upper surface of the workbench body 1. A cooling channel 5 is provided inside the T-slot insert 2. The cooling channels of the multiple T-slot inserts 2 are connected through a connecting pipe 3. An end face joint 4 for connecting with the cooling channel 5 is provided on the side of the workbench body 1. The pipeline inside the workbench is connected to the outside of the machine tool through a drag chain 13. The drag chain 13 is supported by a drag chain bracket 15. Constant temperature cooling water is passed through the end face joint on one side of the workbench. The flow direction of the pipeline inside the workbench is as shown in FIG. Figure 4 As shown, the other side of the workbench returns to the constant temperature cooling chamber, and the workbench is temperature-controlled by constant temperature cooling water to avoid deformation of the workbench due to temperature changes.

[0025] In a specific embodiment, the workbench body 1 is cast by a mineral resin material. The mineral resin material has high damping characteristics, can absorb the vibration of the spindle and the machine tool itself, and improves the surface processing quality of the workpiece. The thermal conductivity is only 1 / 20 of that of cast iron, and is insensitive to short-term temperature changes. During long-term processing, continuous heat is dissipated through the pipes inside the workbench to ensure the temperature stability of the workbench.

[0026] In a specific embodiment, Figure 2 and Figure 5 As shown, the T-slot insert 2 is further provided with a first channel 6 connecting the cooling channel 5 and the top surface of the T-slot insert 2, and an interface for connecting a nozzle is provided on the top surface of the T-slot insert 2. In this embodiment, Figure 3As shown, only constant temperature cooling water is introduced into the cooling channel 5 inside the T-slot insert 2, and the first channel 6 is connected to the cooling channel 5. One or more high-pressure universal nozzles 14 or anti-sputtering nozzles 9 can be connected to the top surface interface of the T-slot insert 2 at different positions on the workbench body 1 according to cooling needs.

[0027] In a specific embodiment, Figure 6 and Figure 7 As shown, the T-slot insert 2 is provided with a plurality of channels inside, the plurality of channels are independent of each other, and the interfaces of the plurality of channels are all provided on the surface of the T-slot insert 2, the plurality of channels are connected with the connecting pipe 3, and the top surface of the T-slot insert 2 is provided with an interface for connecting the nozzle, and a plurality of independent channels are provided inside the T-slot insert 2, and threads are provided at the interfaces, the interfaces that do not need to be connected are sealed by screw plugs 12, and the interfaces that need to be connected are connected to the connecting pipe 3 through pipe joints 11. In this embodiment, five pipelines are provided inside the T-slot insert 2, and after the internal channels of the T-slot insert 2 are connected through the connecting pipe 3, they are connected with the drag chain 13 through the central block insert 16, and the required constant temperature cooling water, hydraulic oil, coolant, cooling oil and cooling gas, etc. can be introduced into different pipelines as needed to meet different work requirements.

[0028] In a specific embodiment, the nozzle is any one of an air nozzle 7 , an aerosol nozzle 8 , an anti-sputtering nozzle 9 and a high-pressure universal nozzle 14 .

[0029] In a specific embodiment, at least one of the top interfaces of the T-slot insert 2 is connected to the nozzle. It should be noted that the interface on the top of the T-slot insert 2 can be connected to any one or more of the gas nozzle 7, the aerosol nozzle 8, the anti-sputtering nozzle 9 and the high-pressure universal nozzle 14;

[0030] When multiple T-slot inserts 2 are connected to at least one gas nozzle 7, high-pressure gas can not only cool the workpiece surface, but also blow away the part processing debris on the worktable surface;

[0031] When a plurality of T-slot inserts 2 are connected to at least one aerosol nozzle 8, the aerosol nozzle 8 is used to rapidly cool the surface of the workpiece;

[0032] When a plurality of T-slot inserts 2 are connected to at least one anti-splash nozzle 9, the constant temperature cooling water in the cooling pipe 5 will be sprayed out at the anti-splash nozzle 9 through the first pipe 6, and the sprayed aerosol can cool the surface of the workpiece and prevent liquid splashing;

[0033] When a plurality of T-slot inserts 2 are connected to at least one high-pressure universal nozzle 14 , the high-pressure universal nozzle will cool the workbench surface in any direction within the spraying range.

[0034] In a specific embodiment, the cooling channels of the T-slot insert 2 are connected in sequence through the connecting pipe 3 to form an S-shaped channel. By connecting the connecting pipe 3 in an S-shape, the cooling area of ​​the workbench and the workbench body can be increased to achieve a better constant temperature control effect.

[0035] In a specific embodiment, a protrusion 10 is provided on the side of the T-slot insert 2. Since the workbench is formed by pouring and curing a mineral resin material around the T-slot insert, the contact area between the T-slot insert 2 and the workbench body 1 can be increased by providing the protrusion 5, thereby preventing the T-slot insert from falling off in the workbench body due to a large force on the workpiece during the parts processing process.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
