Description

Technical Field

[0001] This utility model relates to the field of spindle support technology, and in particular to a spindle connection architecture. Background Technology

[0002] The spindle connection architecture is a mechanical structure in the field of spindle support technology used to achieve a stable connection between the spindle (such as drilling rigs, cutting tools, etc.) and the drive and transmission system, and to assist in completing precise displacement and operation. It is widely used in machining, drilling equipment and other scenarios, and its performance directly affects the machining accuracy and operational stability of the equipment.

[0003] In practical applications, traditional spindle connection architectures have many shortcomings:

[0004] First, the horizontal and vertical displacement adjustment accuracy is low, and it relies heavily on manual or simple transmission structures, which can easily lead to processing errors.

[0005] Secondly, there is a lack of effective dust protection, and dust and debris can easily enter the transmission components (such as lead screws and guide rails), shortening the equipment's lifespan. In addition, cables and pipelines lack orderly storage and protection, and are easily affected by pulling and wear, which can affect circuit safety. Fourthly, the spindle (such as drill bit) is prone to high temperature during operation, which can affect the processing quality, and the cooling system lacks flexibility. Utility Model Content

[0006] To address the aforementioned problems, this invention proposes a spindle connection architecture to more accurately resolve the issues of low adjustment precision and lack of effective dust protection.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes a spindle connection structure, including a gantry frame. A first servo motor is fixedly connected to one outer wall of the gantry frame by screws, and the output shaft of the first servo motor is fixedly connected to a first lead screw by a coupling. A horizontal mounting plate is screwed onto the outer wall of the first lead screw, and a second servo motor is fixedly connected to the top outer wall of the horizontal mounting plate by screws at equal intervals. The output shaft of the second servo motor is fixedly connected to a second lead screw by a coupling, and a vertical lifting plate is screwed onto the outer wall of the second lead screw. A protective cover plate is fixedly connected to one outer wall of the vertical lifting plate by screws, and a drilling rig is fixedly connected to the bottom inner wall of the protective cover plate by screws. The output shaft of the drilling rig is fixedly connected to a drill bit by a coupling.

[0009] Furthermore, a solenoid valve is installed at the bottom of one side of the outer wall of the protective cover, and a bamboo-joint cooling pipe is installed on the bottom outer wall of the solenoid valve.

[0010] Furthermore, the outer wall of the gantry frame is provided with symmetrically distributed slide rails, and the outer wall of the transverse mounting plate is provided with a slider, which is slidably connected to the outer wall of the slide rails.

[0015] Furthermore, a second cable protection bracket is fixedly connected to one side of the outer wall of the electrical control box.

[0016] The beneficial effects of this utility model are:

[0017] The present invention proposes a spindle connection structure, in which a first servo motor drives a first lead screw to achieve the lateral movement of the horizontal mounting plate, and a second servo motor drives a second lead screw to achieve the vertical movement of the vertical lifting plate.

[0025] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0026] Please refer to Figures 1-4 This utility model proposes a spindle connection structure, including a gantry frame 1. A first servo motor 2 is fixedly connected to one outer wall of the gantry frame 1 by screws, and the output shaft of the first servo motor 2 is fixedly connected to a first lead screw 3 by a coupling. A horizontal mounting plate 4 is screwed onto the outer wall of the first lead screw 3, and a second servo motor 5 is fixedly connected to the top outer wall of the horizontal mounting plate 4 by screws at equal intervals. The output shaft of the second servo motor 5 is fixedly connected to a second lead screw by a coupling, and a vertical lifting plate 7 is screwed onto the outer wall of the second lead screw. A protective cover plate 10 is fixedly connected to one outer wall of the vertical lifting plate 7 by screws, and a drilling rig 8 is fixedly connected to the bottom inner wall of the protective cover plate 10 by screws. The output shaft of the drilling rig 8 is fixedly connected to a drill bit 9 by a coupling.

[0027] In the above scheme, the gantry frame 1 serves as an integral support structure. One outer wall of the gantry frame is secured to the first servo motor 2 with screws. The output shaft of the first servo motor 2 is connected to the first lead screw 3 via a coupling. The transverse mounting plate 4 is screwed onto the outer wall of the first lead screw 3. When the first servo motor 2 starts, the first lead screw 3 rotates, causing the transverse mounting plate 4 to move laterally along the slide rail 13. The slider on one side of the transverse mounting plate 4 slides against the slide rail 13, ensuring smooth movement. This structure, through the high-precision transmission characteristics of the first lead screw 3, achieves precise control of the transverse position, which is more efficient and accurate than traditional manual adjustment.

[0028] The top of the horizontal mounting plate 4 is fixed with second servo motors 5 that are evenly distributed. Their output shafts are connected to the second lead screw via a coupling. The vertical lifting plate 7 is screwed to the outer wall of the second lead screw. When the second servo motor 5 is started, the second lead screw rotates and drives the vertical lifting plate 7 to move up and down, thereby adjusting the vertical height of the drill 8 and the drill bit 9. Multiple sets of second servo motors 5 can realize the synchronous or independent operation of multiple drill bits 9, improving processing efficiency.

[0029] A solenoid valve 11 is installed at the bottom of one side of the outer wall of the protective cover plate 10, and a bamboo-joint cooling pipe 12 is installed on the bottom outer wall of the solenoid valve 11.

[0030] With the above solution, the protective cover plate 10 is fixed to one side of the vertical lifting plate 7 with screws, which not only protects the internal drilling rig 8, but also provides an installation base for the solenoid valve 11 at the bottom. The bamboo-joint cooling pipe 12 installed at the bottom of the solenoid valve 11 can be bent at any angle, which makes it convenient to spray coolant at the drill bit 9. The solenoid valve 11 controls the flow of coolant to achieve precise cooling and avoid waste of resources.

[0031] The outer wall of one side of the gantry frame 1 is provided with symmetrically distributed slide rails 13, and the outer wall of one side of the horizontal mounting plate 4 is provided with a slider. The slider is slidably connected to the outer wall of the slide rail 13. One end of the outer wall of one side of the gantry frame 1 is fixedly connected to a first dustproof folding cover 14 by screws, and one end of the outer wall of the first dustproof folding cover 14 is fixedly connected to one end of the outer wall of the horizontal mounting plate 4. A second dustproof folding cover 15 is fixedly connected between the second servo motor 5 and the vertical lifting plate 7.

[0032] With the above solution, one end of the first dustproof folding cover 14 on one side of the gantry frame 1 is connected to the horizontal mounting plate 4. It extends and retracts as the horizontal mounting plate 4 moves, always blocking the exposed parts of the slide rail 13 and the first lead screw 3, preventing dust and debris from entering the transmission area. Similarly, the second dustproof folding cover 15 between the second servo motor 5 and the vertical lifting plate 7 protects the second lead screw from contamination and ensures the smoothness of the lead screw transmission.

[0033] An extension cover 6 is provided on the top outer wall of the protective cover plate 10, and a first cable protection bracket 16 is provided through the inner wall of the extension cover 6. An electrical control box 17 is fixedly connected to the other outer wall of the transverse mounting plate 4 by screws, and the electrical control box 17 is located on the top of the gantry frame 1. A second cable protection bracket 18 is fixedly connected to one outer wall of the electrical control box 17.

[0034] With the above solution, the extension cover 6 at the top of the protective cover plate 10 provides installation space for the first cable protection bracket 16. The bracket penetrates the inner wall of the extension cover 6 and is used to organize the cables connected to the drilling rig 8. The electrical control box 17 on the other side of the horizontal mounting plate 4 is responsible for the equipment circuit control. The second cable protection bracket 18 on its outer wall stores the cables connected to the electrical control box 17. Both together avoid safety hazards caused by messy cables.

[0035] In this embodiment, the first servo motor 2 drives the first lead screw 3 to achieve the lateral movement of the horizontal mounting plate 4, and the second servo motor 5 drives the second lead screw to achieve the vertical movement of the vertical lifting plate 7. With the guidance of the slide rail 13 and the slider, the displacement accuracy and stability of the drilling rig 8 and the drill bit 9 are greatly improved, effectively solving the problem of low adjustment accuracy of the traditional structure and meeting the requirements of high-precision processing.

[0036] The first dustproof folding cover 14 can prevent dust from entering the connection between the gantry frame 1 and the horizontal mounting plate 4 during lateral movement. The second dustproof folding cover 15 can protect the second lead screw from contamination. The first cable protection bracket 16 and the second cable protection bracket 18 can neatly store the cable to avoid pulling and wear. In addition, the bamboo-joint cooling pipe 12 is controlled by the solenoid valve 11 and can be flexibly aimed at the drill bit 9 for cooling. This solves the defects of poor dust protection, easy cable damage and insufficient cooling in the traditional structure and extends the service life of the equipment.

[0037] Working principle: When the device is working, the electrical control box 17 acts as the control core, coordinating the operation of various components: First, according to the processing requirements, the first servo motor 2 starts, driving the horizontal mounting plate 4 to move laterally along the slide rail 13 through the first lead screw 3. At the same time, the first dustproof folding cover 14 extends and retracts with the horizontal mounting plate 4 to protect the transmission components. When the horizontal position is adjusted to the correct position, the second servo motor 5 starts, driving the vertical lifting plate 7 to move up and down through the second lead screw. The second dustproof folding cover 15 extends and retracts synchronously to protect until the drill bit 9 reaches the set height.

[0038] During operation, the drilling rig 8 drives the drill bit 9 to rotate for processing. At this time, the solenoid valve 11 can be opened by the electrical control box 17, and the bamboo-joint cooling pipe 12 sprays coolant onto the drill bit 9 to cool it down. The cables in the first cable protection bracket 16 and the second cable protection bracket 18 provide power and control signals to each motor, drilling rig 8, solenoid valve 11, etc., to ensure circuit stability.

[0039] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
