Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment: A machine tool base, as Figures 1 - 3 shown, includes a machine tool main body base 1. An installation groove 103 is opened on the machine tool main body base 1. Both side walls of the inner cavity of the installation groove 103 are fixedly connected with spring dampers 2. The opposite ends of the two spring dampers 2 are fixedly connected with a fixed rod 201. The outer wall of the fixed rod 201 is slidably connected with two sliding blocks 203 fixedly connected to one end of the spring damper 2. An active rod 204 is movably arranged on both sliding blocks 203. A limiting spring 202 is fixedly connected to the end of the sliding block 203 away from the spring damper 2. An installation block 205 is movably arranged at the end of the active rod 204 away from the sliding block 203; the active rod 204 is arranged in an inclined shape. Due to the inclined shape of the active rod 204, when the active rod 204 drives the sliding block 203 to compress the spring damper 2, it can slide left and right along the outer wall of the fixed rod 201. A storage plate 3 is installed on the side wall surface of the installation block 205 away from the sliding block 203. Both the front and rear ends of the top of the machine tool main body base 1 are fixedly installed with sleeves 4. A compression spring 402 is fixedly installed at the bottom of the inner cavity of the sleeve 4. A buffer rod 401 is sleeved in the inner cavity of the sleeve 4. The bottom of the buffer rod 401 is connected to the top of the compression spring 402. The top of the buffer rod 401 is fixedly connected to the bottom of the storage plate 3. Support legs 101 are installed at the four end points of the bottom of the machine tool main body base 1. A heat dissipation grille 102 is opened on the side wall surface of the machine tool main body base 1. Through the cooperation of the heat dissipation grille 102 and the support legs 101, the air circulation at the machine tool main body base 1 can be accelerated.

[0024] This application also proposes a machine tool. This machine tool includes the above-mentioned machine tool base. The specific structure of the above-mentioned machine tool base refers to the above-mentioned embodiment. Since this machine tool adopts all the technical solutions of the above-mentioned all embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be described in detail here.

[0025] The working principle of the present utility model:

[0026] During use, when the machine tool is working, it will vibrate. Due to the action of gravity, the placement plate 3 approaches the main body seat 1 of the machine tool. At this time, the sliding block 203 is driven to compress the spring damper 2 and slide left and right along the outer wall of the fixed rod 201. Under the action of the two spring dampers 2, the impact force received is weakened, and the vibration of the placement plate 3 can be reduced.

[0027] During use, through the cooperation of the heat dissipation grille 102 and the support leg 101, the air circulation at the main body seat 1 of the machine tool can be accelerated, and the heat dissipation effect is good, avoiding excessive heat accumulation inside the CNC machine tool, which may cause some precision components inside the CNC machine tool to expand due to heat and deform.

[0028] For the sake of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will be positioned as "below" or "under" other devices or structures after inversion. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used here will be made.

[0029] It should be noted that the terms used here are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used here, 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, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0030] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that comprises a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0031] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the description is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
