Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and more specifically, it relates to a machine tool column. Background Technology

[0002] The front end of a machine tool column is typically equipped with vertically extending guide rails, which serve as a sliding connection for mounting the power spindle assembly. Due to the large mass of the power spindle assembly, loading it onto the mounting platform causes a slight downward tilt, reducing the installation accuracy of the equipment and resulting in poor overall performance. Therefore, this invention proposes a machine tool column. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a machine tool column with high installation accuracy.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to a machine tool column, comprising a column body. The column body has vertically extending clearance holes on its front and rear sides. A first linear guide rail is provided on the front end face of the column body, and a second linear guide rail is provided on the rear end face of the column body, respectively, on the left and right sides of the clearance holes. A first slider is slidably connected to the first linear guide rail, and a first mounting platform is provided on the first slider. A second slider is slidably connected to the second linear guide rail, and a second mounting platform is provided on the second slider. A compensation hole is provided on the second mounting platform, and a compensation column, one end of which is connected to the first mounting platform, passes through the compensation hole. The diameter of the compensation column is smaller than the diameter of the compensation hole. A fixing plate is provided above or below the compensation column on the second mounting platform. A fine-tuning screw, one end of which abuts against the compensation column, is threaded onto the fixing plate. The other end of the fine-tuning screw has a rotating part.

[0005] The present invention is further configured such that: the compensation column is provided with a groove, the bottom of the groove is flat, and one end of the fine-tuning screw extends into the groove and abuts against the bottom of the groove.

[0006] The present invention is further configured such that: a compression spring is fitted on the fine-tuning screw, with one end abutting against the fixed plate and the other end abutting against the rotating part.

[0007] The present invention is further configured such that a rotating side hole is provided on the rotating part.

[0008] The present invention is further configured such that the fixing plate is located above the compensation column.

[0009] In summary, the present invention has the following beneficial effects: the machine tool column involved in the present invention, by rotating the fine adjustment screw, can pry and compensate for the deformation allowance of the compensation column, so as to restore its original installation accuracy. This ensures that the installation accuracy can still be guaranteed after a heavy-duty power spindle assembly is loaded on the first mounting table. The overall function is perfect and the practicality is strong. Attached Figure Description

[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See Figure 1 and Figure 2 As shown, the machine tool column involved in this embodiment includes a column body 1. The column body 1 has clearance holes 2 extending vertically on its front and rear sides. The clearance holes 2 have a first linear guide rail 3 on the front end face of the column body and a second linear guide rail 4 on the rear end face of the column body on its left and right sides, respectively. A first slider 5 is slidably connected to the first linear guide rail 3. A first mounting platform 6 is provided on the first slider 5. A second slider 7 is slidably connected to the second linear guide rail 4. A second mounting platform 8 is provided on the second slider 7. A compensation hole 9 is provided on the second mounting platform 8. A compensation column 10 connected to the first mounting platform 6 passes through the compensation hole 9. The diameter of the compensation column 10 is smaller than the diameter of the compensation hole 9. A fixing plate 11 is provided on the second mounting platform 8 above the compensation column 10. A fine adjustment screw 12 with one end abutting against the compensation column is threaded onto the fixing plate 11. The other end of the fine adjustment screw 12 is provided with a rotating part 13.

[0016] Furthermore, the rotating part 13 is provided with a lever side hole 15.

[0017] In this embodiment, when the power spindle assembly is loaded on the first mounting platform 6, the first mounting platform 6 will undergo slight deformation due to the increased load on the first mounting platform 6, and the compensation column 10 will also shift. At this time, the compensation column 10, which can move radially within the compensation hole 9, can be lifted by rotating the fine-tuning screw 12 to compensate for the deformation allowance and achieve the effect of adjusting the installation accuracy.

[0018] Example 2

[0019] See Figure 1 and Figure 2 As shown, the machine tool column involved in this embodiment is further configured based on embodiment 1, wherein the compensation column 10 is provided with a groove 14, the bottom of the groove 14 is flat, and one end of the fine adjustment screw 12 extends into the groove and abuts against the bottom of the groove.

[0020] In this embodiment, the flat-bottomed groove 14 is provided to increase the contact surface and make fine-tuning more precise.

[0021] Example 3

[0022] See Figure 1 and Figure 2 As shown, the machine tool column involved in this embodiment is further configured, based on embodiment 1, with a compression spring (not shown) fitted on the fine-tuning screw 12, one end of which abuts against the fixed plate and the other end against the rotating part.

[0023] In this embodiment, the compression spring serves to reinforce the fine-tuning screw 12 and prevent loosening.

[0024] The machine tool column involved in this utility model can be pried and compensated for the deformation allowance of the compensation column by rotating the fine adjustment screw, so as to restore its original installation accuracy. This ensures that the installation accuracy can still be guaranteed after a heavy-duty power spindle assembly is loaded on the first mounting table. The overall function is perfect and the practicality is strong.
