[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] like Figures 1 to 5 As shown, a vertical deep hole drilling machining center is characterized by comprising a base 1, a worktable 2 on the upper side of the base 1, a column 3 fixedly mounted on the upper side of the base 1, a spindle structure 5 connected to the outer side of the column 3 via a vertical moving structure 4, the spindle structure 5 comprising a spindle housing 51, a fixing hole in the spindle housing 51, a spindle 52 fixed at the fixing hole, a slide block 53 mounted on the outer side of the spindle housing 51 via a vertical guide rail slider, a slide block motor 54 for controlling the up and down movement of the slide block 53 on the side of the slide block 53, and a U-shaped bracket 531 on the lower side of the slide block 53, the U-shaped bracket 531 having a through hole 532 corresponding to the spindle.

[0023] The slide 53 is moved up and down by a slide motor 54 on the outside of the spindle housing 51. The slide 53 is equipped with a U-shaped bracket 531. During the machining process, the spindle tool can be guided and supported by the through hole set at the position of the U-shaped bracket 531, thereby avoiding tool vibration during deep hole machining, ensuring the coaxiality of the hole and other requirements during deep hole machining, and improving machining accuracy.

[0024] At this time, the U-shaped bracket 531 needs to be moved up and down by the slide motor 54. Therefore, in this embodiment, the slide 53 includes vertical parts 533 on both sides of the main shaft. The U-shaped bracket 531 is located at the bottom of the vertical part 533. The side of the vertical part 533 is also provided with a connecting part 534 for connecting the upper side of the vertical part 533. The connecting part 534 is provided with a clearance position, and the main shaft is located in the clearance position. The U-shaped bracket 531 needs to be adjusted in position relative to the spindle to meet different processing requirements. Therefore, to facilitate the adjustment of the U-shaped bracket 531, the slide 53 also includes vertical portions 533 on both sides of the spindle. The U-shaped bracket 531 is located at the bottom of the vertical portions 533. Thus, the U-shaped bracket 531 and the two vertical portions 533 form a U-shape. To improve the overall stability of the slide 53, a connecting portion 534 is provided between the two vertical portions 533. The connecting portion 534 is located at different heights of the vertical portions 533, thereby increasing the overall strength of the slide 53. At the same time, since the connecting portion 534 also moves up and down with the slide 53, a clearance position is provided in the connecting portion 534 to prevent it from colliding with the spindle during movement. The spindle is located inside the clearance position. This ensures the normal movement of the slide 53 as a whole during the up and down movement of the connecting portion 534.

[0025] Specifically, the connecting part 534 is an arc-shaped connecting part 534. There are two arc-shaped connecting parts 534, located on both sides of the vertical part 533, and the openings of the arc-shaped connecting parts 534 face different directions. The other two arc-shaped connecting parts 534 are located in the middle and at the top of the vertical part 533, respectively. The fact that the openings of the two arc-shaped connecting parts 534 face different directions is equivalent to surrounding the main shaft on the inner side, making the overall structure more compact, while ensuring the overall strength of the slide 53.

[0026] The arc-shaped connecting portion 534 is mainly used to increase the strength of the vertical portion 533 of the slide block 53. To further enhance the strength of the arc-shaped connecting portion 534, in this embodiment, two reinforcing ribs 5341 are provided on the outer side of the arc-shaped connecting portion 534, located on the upper and lower sides respectively. The reinforcing ribs 5341 are located on the outer side of the arc-shaped connecting portion 534. Adding the reinforcing ribs 5341 increases the strength of the arc-shaped connecting portion 534, thereby increasing the overall strength of the slide block 53.

[0027] At this point, the slide 53 is connected to the spindle housing 51 via a slider at the vertical section 533. To improve the strength of the vertical section 533, it includes two parallel vertical surfaces 5331. A connecting surface 5332 is provided on the side of the two vertical surfaces 5331 near the spindle. The vertical surfaces 5331 and the connecting surface 5332 form a U-shaped structure with an opening. Several transverse reinforcing plates 5333 are provided on the inner side of the vertical surfaces 5331 and the connecting surface 5332. A V-groove is provided on the transverse reinforcing plates 5333 near the opening. Thus, the vertical section 533 of the slide 53, under the action of the vertical surfaces 5331, the connecting surface 5332, and the transverse reinforcing plates 5333, can ensure overall strength while reducing weight. This lowers the power required for the slide 53 to move up and down, thereby reducing equipment costs. Meanwhile, a V-groove is provided near the opening of the transverse reinforcing plate 5333, which can improve the strength between the transverse reinforcing plate 5333 and the vertical surface 5331 and reduce cracking problems.

[0028] The slide motor 54 is used to drive the slide 53 to move outside the spindle housing 51. In this embodiment, the slide motor 54 is fixed to the outside of the arc-shaped connecting part 534 at the top position. The shaft of the slide motor 54 is connected to a lead screw 541, which is connected to the spindle housing 51 through a sliding joint. At this time, the sliding joint is fixed to the spindle housing 51. Thus, when the slide motor 54 controls the lead screw 541 to rotate, since the sliding joint does not move up and down, the lead screw 541 will also move up and down when rotating. Consequently, the slide motor 54 and the slide 53 will move up and down, thereby achieving the control of the up and down movement of the slide 53. At this time, the slide motor 54 is fixed to the outside of the arc-shaped connecting part 534 at the top of the slide 53, that is, on the upper side of the spindle housing 51, which makes the overall structure more compact.

[0029] During the up-and-down movement of the slide 53, the lead screw 541 also moves up and down. Therefore, to ensure smooth movement of the lead screw 541, in this embodiment, the spindle housing 51 is provided with a vertical through hole 511. The vertical through hole 511 is located at the projected position of the lead screw 541. When relative movement occurs between the lead screw 541 and the spindle housing 51, the lead screw 541 moves up and down within the vertical through hole 511. Thus, during the up-and-down movement of the slide 53, the lead screw 541 also moves up and down synchronously. At this time, the inner diameter of the vertical through hole 511 is larger than the outer diameter of the lead screw 541, and the lead screw 541 moves up and down within the vertical through hole 511, ensuring smooth movement of the lead screw 541 during the up-and-down movement and preventing collision with the spindle housing 51.

[0030] At this time, a spindle motor for controlling the rotation of the spindle is also provided on the outside of the spindle housing 51. In this embodiment, the spindle housing 51 also includes a fixing platform 512 on the side of the fixing hole. The fixing platform 512 has a recessed hole 513 in the middle. The spindle motor is fixed at the fixing platform 512. The spindle motor shaft is connected to the spindle through a conveyor belt for driving the spindle to rotate. The conveyor belt is located at the lower hole position. The spindle motor is connected to the spindle through the conveyor belt to control the rotation of the spindle.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
