Description

Technical Field

[0001] The utility model relates to the field of machining center equipment, and more specifically, it relates to an inner circulation cooling high-stability base. Background Art

[0002] Machining centers are applied in the mechanical processing industry. As one of the important components of a machining center, the base of a machining center has the function of bearing most of the weight of the vertical machining center components. In addition to this, a firm and stable base can reduce the vibration and deformation of the machine tool during the machining process, thereby ensuring the machining accuracy.

[0003] However, during the machining process of existing machining centers on objects, due to the strong vibration of the machining components operating inside, the base of the machining center will generate a certain amount of shaking, which will affect the accuracy of object machining.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

A cavity is opened in the lower base, and a number of ribs are fixedly arranged in the cavity. The bottom surface of the cavity is set as a fully enclosed structure, and a load-bearing casting is arranged in the cavity.

[0007] The utility model is further arranged as: A cooling pipe penetrating the load-bearing casting is also arranged in the cavity, and the water inlet and outlet of the cooling pipe both extend to the outside of the lower base.

[0008] The utility model is further arranged as: Temperature monitoring modules are arranged at both the water inlet and outlet of the cooling pipe.

[0009] The utility model is further arranged as: A flow monitoring module is also arranged at the water inlet of the cooling pipe.

[0010] The utility model is further arranged as: The middle base is of an integral structure.

One end of the chip removal groove is fixedly provided with a chip removal baffle, and waterproof strips are fixedly arranged around the middle base.

[0012] The utility model is further arranged as: An oil guiding channel is opened in the middle base, and oil passing holes communicating with the oil guiding channel are opened on the upper base.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By increasing the weight of the lower base through the weight-bearing casting, the overall center of gravity of the machining center base is lowered, thereby effectively eliminating the vibrations generated by the axial rapid movement and machining. The weight-bearing casting plays a role in absorbing vibrations, making the machining center base more stable and the machining accuracy better. Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment:

[0023] An inner circulation cooling high-stability base, such asFigures 1 - 5 As shown in the figure, it includes a lower base 1, a middle base 2, and an upper base 3 fixedly connected from bottom to top. The machining center base is formed by fixedly connecting the lower base 1, the middle base 2, and the upper base 3 in sequence. A cavity is provided in the lower base 1, and a number of ribs are fixedly arranged in the cavity to enhance the load-bearing capacity of the lower base 1 through the number of ribs. The bottom surface of the cavity is set as a fully enclosed structure, and a load-bearing casting 4 is arranged in the cavity to increase the weight of the lower base 1 through the load-bearing casting 4, so that the overall center of gravity of the machining center base moves downward, thereby effectively eliminating the vibration generated by the axial rapid movement and machining. The load-bearing casting 4 plays a role in absorbing vibration, making the machining center base more stable and the machining accuracy better.

[0024] As Figure 2 and Figure 5 shown in the figure, a cooling pipe 5 penetrating the load-bearing casting 4 is also arranged in the cavity. The inlet and outlet of the cooling pipe 5 both extend to the outside of the lower base 1. By introducing coolant into the cooling pipe 5, the cooling pipe 5 provides a good cooling effect for the load-bearing casting 4, ensuring effective heat dissipation of the lower base 1 and the overall machining center base, and ensuring that the equipment can operate stably even in a high-temperature environment.

[0025] The load-bearing casting 4 is made of mineral casting. Thus, during the production process, the cooling pipe 5 can be first laid in the mold, and then the flowable slurry used to form the mineral casting is injected into the mold. Then, through heating, pressurization and other methods, its solidification is promoted. After the artificial granite is completely solidified, it is taken out of the mold, and the connection structure of the cooling pipe 5 and the load-bearing casting 4 can be formed.

[0026] As Figures 1 - 5 shown in the figure, temperature monitoring modules 6 are arranged at both the inlet and outlet of the cooling pipe 5. The temperature monitoring module 6 uses temperature sensors. By detecting the temperature difference between the inlet and outlet water temperatures of the cooling pipe 5 through the temperature sensors, the temperature of the load-bearing casting 4 is ensured to be constant, and the current temperature of the load-bearing casting 4 can be fed back, thereby ensuring effective heat dissipation of the overall machining center base.

[0027] And a flow monitoring module 7 is also arranged at the inlet of the cooling pipe 5. The flow monitoring module 7 uses a turbine flow sensor to monitor whether the coolant is flowing normally to ensure the normal use of the cooling pipe 5.

[0028] The middle base 2 is of an integral structure, and the rigidity is greatly improved through the integral structure, effectively maintaining the best dynamic horizontal accuracy.

[0029] As Figure 1As shown in the figure, chip removal grooves 8 are symmetrically arranged on both sides of the upper base 3 along the middle base 2. The chip removal grooves 8 on both sides facilitate the collection and export of waste chips falling from the upper base 3. At the same time, the chip removal grooves 8 are inclined with respect to the horizontal plane, so that the waste chips will be automatically exported under the action of gravity. And a chip removal baffle 9 is fixedly arranged at the end with a higher horizontal height of the chip removal groove 8 to close one end of the chip removal groove 8. At the same time, waterproof strips 10 are fixedly arranged around the middle base 2 to limit the random movement of the cutting fluid through the waterproof strips 10.

[0030] As Figure 4 shown, an oil guiding channel 11 is provided in the middle base 2, and oil passing holes 12 communicating with the oil guiding channel 11 are provided on the upper base 3. Through the cooperation of the oil guiding channel 11 and the oil passing holes 12, the effect of exporting the excess lubricating oil on the track of the upper base 3 is achieved, and the export path is separated independently, avoiding mixing with the cutting fluid, prolonging the service life of the cutting fluid, reducing costs, being environmentally friendly, and not easily generating a foul smell.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
