When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0020] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0022] Unless defined otherwise, 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 application belongs.
[0023] like Figure 1As shown, an embodiment of the utility model provides a high-speed gantry drilling and tapping machine, including a drilling and tapping unit 10, a Z-axis displacement assembly 20, an X-axis displacement assembly 30, a Y-axis displacement assembly 40 and a tool magazine assembly 50. Among them, the drilling and tapping unit 10 is connected to the Z-axis displacement assembly 20, and the Z-axis displacement assembly 20 is provided with the degree of freedom to move along the Z-axis. The Z-axis displacement assembly 20 is connected to the X-axis displacement assembly 30, and the X-axis displacement assembly 30 is provided with the degree of freedom to move along the X-axis. The X-axis displacement assembly 30 is connected to the Y-axis displacement assembly 40, and the Y-axis displacement assembly 40 is provided with the degree of freedom to move along the Y-axis. Therefore, through the arrangement of the Z-axis displacement assembly 20, the X-axis displacement assembly 30 and the Y-axis displacement assembly 40, the drilling and tapping unit 10 can have three-axis displacement degrees of freedom to successfully complete the drilling and tapping operation.
[0024] At the same time Figure 2 As shown, the tool magazine assembly 50 includes a tool magazine base 51, a tool clamp mounting plate 52 and a plurality of tool clamps 53. Among them, a first slider 54 is provided on the upper surface of the tool magazine base 51, and a first guide rail 55 is provided on the lower surface of the tool clamp mounting plate 52. The first slider 54 and the first guide rail 55 are slidably matched so that the tool clamp mounting plate 52 can move along the first guide rail 55. At the same time, a switching cylinder 56 is also provided on the upper surface of the tool magazine base 51. The piston rod end of the switching cylinder 56 is connected to the tool clamp mounting plate 52 so as to control the advance and retreat of the tool clamp mounting plate 52 through the extension and retraction of the switching cylinder 56. A plurality of mounting ports are provided on the tool clamp mounting plate 52, and a tool clamp 53 is installed on each mounting port. The tool clamp 53 is used to place tools of corresponding specifications to facilitate tool change in the drilling and tapping part 10.
[0025] The tool holders 53 can be set to different specifications and are distributed side by side on the tool holder mounting plate 52. Tools of corresponding specifications are placed on different tool holders 53. When the drilling and tapping part 10 needs to replace the tool during operation, it can be directly moved to the top of the tool holder mounting plate 52 for tool replacement, or when the tool of the same specification needs to be replaced with a new tool after being worn, it can be directly replaced, thereby avoiding the large-scale movement of the drilling and tapping part 10 to reduce the working efficiency. It is understandable that some tool holders 53 on the tool holder mounting plate 52 are vacant to facilitate the drilling and tapping part 10 to replace the old tool.
[0026] It should be noted that in this embodiment, the tool holder mounting plate 52 is close to the working area of the drilling and tapping unit 10 when advancing, so as to facilitate tool changing of the drilling and tapping unit 10. When the old tools on each tool holder 53 need to be removed and replaced, the tool holder mounting plate 52 retreats to a distant point to unload the old tools. The tool holder 53 clamps the tools by the elastic force of (metal or other) materials, and the drilling and tapping unit 10 fixes or removes the tools by means of beating the tools, etc.
[0027] At the same time Figure 3As shown, the Z-axis displacement assembly 20 includes a Z-axis displacement platform 21 and a drilling and tapping mounting plate 22. Among them, a second slider 23 is provided on the Z-axis displacement platform 21, and a second guide rail 24 is provided on the drilling and tapping mounting plate 22. The second slider 23 and the second guide rail 24 are slidably matched so that the drilling and tapping mounting plate 22 can move along the Z-axis displacement platform 21, that is, in the Z-axis direction. At the same time, a first screw mechanism 25 is also provided on the Z-axis displacement platform 21, and the drilling and tapping mounting plate 22 is driven by the first screw mechanism 25. Since the first screw mechanism 25 itself is a common form in the prior art, its specific installation method is not repeated.
[0028] In this embodiment, the drilling and tapping part 10 is arranged on the drilling and tapping mounting plate 22, and the drilling and tapping part 10 includes a spindle 11, a spindle seat 12, a spindle drive motor 13, and a tool-beating cylinder 14. Among them, the spindle seat 12 is fixedly connected to the drilling and tapping mounting plate 22, the spindle 11 is arranged on the spindle seat 12, and the spindle drive motor 13 is connected to the spindle 11 through a synchronous belt mechanism 15 to drive the spindle 11 to rotate and drill. The tool-beating cylinder 14 is also arranged on the spindle seat 12, which is used to realize the automatic replacement of the tool.
[0029] In this embodiment, the X-axis displacement assembly 30 includes a gantry and an X-axis displacement beam, the X-axis displacement beam is fixedly connected to the Z-axis displacement platform, the X-axis displacement beam and the gantry are also slidably connected by a guide rail slider, and the X-axis displacement beam is driven to move relative to the gantry along the X-axis direction by a second screw mechanism. The Y-axis displacement assembly 40 includes a Y-axis displacement seat, the gantry and the Y-axis displacement seat are also slidably connected by a guide rail slider, and the gantry is driven to move relative to the Y-axis displacement seat along the Y-axis direction by a third screw mechanism. Relying on the setting of the Y-axis displacement seat and the gantry, the drilling and tapping part 10 can be better supported during operation, further improving stability and reliability.
[0030] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.
[0031] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
