Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically a precision machine tool casting with an integrally formed positioning reference. Background Technology

[0002] In the manufacturing process of precision machine tools, castings, as key basic components, play a decisive role in the overall performance of the machine tool due to their quality and precision. Traditionally, heat dissipation of precision machine tool castings is achieved by welding heat sink fins after the casting is formed. This method has many drawbacks, including poor heat dissipation and affecting the overall structure of the casting. Utility Model Content

[0003] The purpose of this invention is to provide a precision machine tool casting with an integrally formed positioning reference, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is: a precision machine tool casting integrally formed with a positioning reference, including a main frame, the side wall of the main frame is provided with an annular heat dissipation part, the heat dissipation part includes an annular groove opened on the outside of the main frame, the annular groove is provided with an annular spacer integrally formed with the main frame, the spacer has a notch on one side, and the spacer divides the annular groove into a guide groove for winding water-cooled heat exchange tubes.

[0005] The effects achieved by the above components are as follows: the water-cooled heat exchange tubes are wound inside the guide grooves. When the coolant flows inside the tubes, it makes full contact with the main frame through the annular grooves, carrying away the heat generated by the main frame during the operation of the machine tool, thus achieving efficient heat dissipation. This increases the heat dissipation area of ​​the casting, improves heat dissipation efficiency, and avoids affecting the machining accuracy and stability of the machine tool due to excessively high casting temperatures. At the same time, the one-piece molded structure ensures the connection strength between the heat dissipation part and the main frame, avoiding the problem of easy detachment of traditional welded heat dissipation fins.

[0006] Preferably, the bottom of the outer wall of the main frame is provided with a plurality of evenly distributed positioning grooves, the height of which is half of the height of the main frame.

[0007] The effect achieved by the above components is that the positioning groove can precisely cooperate with the positioning structure on other components. Through the limiting effect of the positioning groove, the installation position of the main frame can be quickly and accurately determined, thus achieving the purpose of precise positioning, improving the efficiency and accuracy of machine tool assembly, and ensuring the accuracy of the relative position between the various components of the machine tool.

[0008] Preferably, a connecting block is fixed at the center of the inner side of the bottom end of the main frame, and corner blocks are provided at the inner corners of the bottom end of the main frame. Connecting holes are provided on the bottom side of the connecting block and the corner blocks.

[0009] The aforementioned components achieve the following effects: During the installation and fixing of the machine tool, the connecting holes can be used to insert bolts and other connectors, firmly connecting the main frame to the machine tool base or other supporting components. The connecting blocks and corner blocks are distributed at different positions at the bottom of the main frame, evenly distributing the load borne by the main frame, enhancing the stability of the connection between the main frame and other components, and achieving a secure connection.

[0010] Preferably, the inner sidewall at the bottom of the main frame is provided with evenly distributed corner plates.

[0011] The effects achieved by the above components are as follows: the corner plate can increase the structural strength of the inner wall at the bottom of the main frame. During the operation of the machine tool, when the main frame is subjected to external forces, the corner plate can effectively disperse the stress and prevent the inner wall at the bottom of the main frame from deforming or being damaged.

[0012] Preferably, the top of the main frame is provided with a weight-reducing slot.

[0013] The effect achieved by the above components is that, without affecting the structural strength and performance of the main frame, the weight-reducing slots reduce the amount of material used in the castings and lower the overall weight of the castings.

[0014] This utility model provides a precision machine tool casting with an integrally formed positioning reference, which has the following improvements and advantages compared with the prior art:

[0015] Firstly, this utility model allows the water-cooled heat exchange tube to be wound inside the guide groove. When the coolant flows inside the tube, it makes full contact with the main frame through the annular groove, carrying away the heat generated by the main frame during the operation of the machine tool. This achieves the purpose of efficient heat dissipation, increases the heat dissipation area of ​​the casting, improves the heat dissipation efficiency, and avoids the machining accuracy and stability of the machine tool being affected by the excessive temperature of the casting.

[0016] Secondly, the positioning groove of this utility model can precisely cooperate with the positioning structure on other components. Through the limiting effect of the positioning groove, the installation position of the main frame can be quickly and accurately determined, achieving the purpose of precise positioning, improving the efficiency and accuracy of machine tool assembly, and ensuring the accuracy of the relative position between the various components of the machine tool.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved precision machine tool casting with an integrally formed positioning reference. The technical solution of this utility model is as follows:

[0024] In embodiments of this utility model, such as Figures 1-2As shown, a precision machine tool casting with an integrally formed positioning reference includes a main frame 1. Multiple evenly distributed positioning grooves 3 are provided at the bottom of the outer wall of the main frame 1. The height of each positioning groove 3 is half the height of the main frame 1. The positioning grooves 3 can precisely cooperate with positioning structures on other components. Through the limiting effect of the positioning grooves 3, the installation position of the main frame 1 can be quickly and accurately determined, achieving the purpose of precise positioning. A connecting block 6 is fixed at the center of the inner side of the bottom end of the main frame 1. Corner blocks 8 are provided at the inner corners of the bottom end of the main frame 1. Connecting holes 7 are provided on the sides of the bottom ends of the connecting blocks 6 and corner blocks 8. During the installation and fixing of the machine tool, the connecting holes 7 can be used to pass through bolts and other connecting parts to firmly connect the main frame 1 to the machine tool base or other supporting components. Connecting blocks 6 and corner blocks 8 are distributed at different positions at the bottom of the main frame 1, which can evenly distribute the load borne by the main frame 1. Evenly distributed corner plates 5 are provided on the inner sidewall of the bottom of the main frame 1. The corner plates 5 can increase the structural strength of the inner sidewall of the bottom of the main frame 1. During machine tool operation, when the main frame 1 is subjected to external forces, the corner plates 5 can effectively disperse stress and prevent deformation or damage to the inner sidewall of the bottom of the main frame 1. A weight-reducing slot 2 is provided at the top of the main frame 1. Without affecting the structural strength and performance of the main frame 1, the weight-reducing slot 2 reduces the amount of material used in the casting. This reduces the overall weight of the casting. The main frame 1 has an annular heat dissipation part 4 on its side wall. The heat dissipation part 4 includes an annular groove 41 opened on the outside of the main frame 1. An annular spacer 42 integrally formed with the main frame 1 is provided in the annular groove 41. A notch 43 is opened on one side of the spacer 42. The spacer 42 divides the annular groove 41 into a guide groove for winding water-cooled heat exchange tubes. The water-cooled heat exchange tubes are wound in the guide grooves. When the coolant flows in the tubes, it makes full contact with the main frame 1 through the annular groove 41, carrying away the heat generated by the main frame 1 during the operation of the machine tool, thus achieving the purpose of efficient heat dissipation.

[0025] The working principle of the precision machine tool casting with integrated positioning reference provided by this utility model is as follows: The water-cooled heat exchange tube is wound in the guide groove. When the coolant flows in the tube, it fully contacts the main frame 1 through the annular groove 41, which carries away the heat generated by the main frame 1 during the operation of the machine tool, thereby achieving efficient heat dissipation. This increases the heat dissipation area of ​​the casting and improves the heat dissipation efficiency, avoiding the impact of excessive casting temperature on the machining accuracy and stability of the machine tool. The positioning groove 3 can be precisely matched with the positioning structure on other components. Through the limiting effect of the positioning groove 3, the installation position of the main frame 1 can be quickly and accurately determined, achieving the purpose of precise positioning. During the installation and fixing of the machine tool, the connecting hole 7 can be used to pass through bolts and other connecting parts to firmly connect the main frame 1 to the machine tool base or other supporting components. The connecting block 6 and corner block 8 are distributed at different positions at the bottom of the main frame 1, which can evenly distribute the load borne by the main frame 1.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
