Description
Technical Field
[0001] The utility model relates to the technical field of cutting machine tool structures, in particular to a machine tool with a foam aluminum filling structure. Background Art
[0002] Nowadays, machining requires frequent use of cutting machine tools. With rapid development, the requirements for cutting speed, feed speed and high machining accuracy are getting higher and higher. When the speed is very high, the machine tool system will have serious vibration, which will affect the machining accuracy and service life. The workbench usually has to perform high-speed reciprocating motion during the machine tool processing process, so high requirements are placed on its lightness, and vibration and noise should be avoided as much as possible. Since severe vibration during the processing will affect the accuracy and service life, another type of filler workbench is selected to reduce vibration. The requirements for the filler are: high dynamic stiffness, lightness, and damping and shock absorption performance.
[0003] For example, in the patent application with publication number CN104175130A in the prior art, since the entire workbench is a pure cast iron workbench structure, this may cause serious vibration and affect the processing accuracy and service life. Therefore, a foam aluminum filled structure machine tool is needed to solve the above technical problems. Utility Model Content
[0004] In view of this, the utility model provides a foam aluminum filled structure machine tool to solve the problem that the prior art may cause serious vibration and affect the processing accuracy and service life.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A machine tool with a foam aluminum filling structure comprises a cast iron layer, a concave cavity is formed inside the cast iron layer, a plurality of strip grooves connected to the concave cavity are arranged at the top of the middle part of the concave cavity, the bottom ends of both ends of the concave cavity are connected to trapezoidal grooves, and the concave cavity, the strip grooves and the trapezoidal grooves are all filled with a foam aluminum core.
[0007] Furthermore, a row of T-shaped grooves is provided at the upper end of the cast iron layer.
[0008] Furthermore, a dovetail groove is provided at the bottom of the cast iron layer.
[0009] The beneficial effects of the utility model are:
[0010] The utility model has low cost and wide application range. By compounding the foam aluminum core and the cast iron layer, it has the physical properties of good rigidity, damping and vibration reduction, noise reduction, energy absorption and heat insulation, and electromagnetic shielding. When it is subjected to the maximum allowable load, its deformation will not exceed the specified value. When the large part itself or other parts move on the large part, the change in static rigidity is also correspondingly small. It has the mechanical properties of high specific strength and specific rigidity. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying creative work.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] Please refer to the attached Figure 1 The utility model provides a foam aluminum filling structure machine tool, including a cast iron layer 1, a concave cavity is formed inside the cast iron layer 1, and a plurality of strip grooves connected to the concave cavity are arranged at the top of the middle part of the concave cavity, and the bottom ends of the two ends of the concave cavity are connected with trapezoidal grooves, and the trapezoidal grooves connected at the bottom ends can also make the entire machine tool more stable, and the concave cavity, the strip grooves and the trapezoidal grooves are all filled with a foam aluminum core 2, and the strip grooves and the trapezoidal grooves of the concave cavity can more firmly support the foam aluminum core 2 in the cast iron layer 1. The filling structure is used to replace the previous pure cast iron structure, which can effectively improve the lightness of the workbench, while improving the moving speed and acceleration sensitivity, and making it easy to control the speed. Since the foam aluminum core 2 has the physical properties of damping and vibration reduction, energy absorption, heat insulation and electromagnetic shielding, and the mechanical properties of high specific strength and specific stiffness, compared with cast iron structural components, while meeting the stiffness requirements, it can also significantly improve the cutting accuracy of the equipment and reduce noise.
[0017] Preferably, a row of T-slots 3 are provided at the upper end of the cast iron layer 1 for installing fixtures to fix the processed parts, replacing manpower, which is safer and more accurate.
[0018] Preferably, a dovetail groove 4 is provided at the bottom of the cast iron layer 1 to improve the bottom of the cutting machine. The dovetail groove 4 is used to ensure a firm connection with the machine guide rail. At the same time, the dovetail groove 4 can increase the load-bearing capacity of the wall, making the device more sturdy and durable.
[0019] The specific operation method of the utility model is:
[0020] First, the dovetail slot 4 under the machine tool is installed along the machine tool guide rail and reinforced at one end with screws. Secondly, a clamping device is installed in the T-slot 3 to clamp the processed part, and then the machine tool is turned on to cut the part.
[0021] Since the utility model replaces the cast iron inside the cavity with a foam aluminum core, it can reduce the impact of vibration on the entire machine while ensuring rigidity, and can also increase cutting sensitivity, improve equipment cutting accuracy, and ensure cutting accuracy while ensuring personnel safety.
