Description

Technical Field

[0001] The invention relates to the technical field of drilling and milling equipment, in particular to a double 45-degree tool magazine arrangement structure type of a double-head drilling and milling center. Background Art

[0002] Double-head drilling and milling integrates drilling and milling processes in one machining center, and uses two tools for collaborative processing. The core idea is to achieve multi-station processing of workpieces through double-head design, significantly improving processing efficiency and flexibility.

[0003] During operation, the fixture fixes the workpiece on the worktable, and then the first drive motor controls one cutter head for drilling, while the second drive motor controls the other cutter head for milling. The two heads can move independently at the same time, thus completing two different processes while keeping the workpiece stable. This design reduces the number of workpiece movements, reduces the non-processing time of the machine tool, and improves the overall efficiency of the processing process.

[0004] At present, the base of the existing double-head drilling and milling machining center is integrated. Since there are multiple motors inside, the multiple motors will affect each other during the simultaneous vibration process. The vibrations will interfere with each other, which not only aggravates the noise pollution, but also significantly reduces the machining accuracy and product quality. Summary of the invention

[0005] The present application provides a double 45-degree tool magazine arrangement structure type for a double-head drilling and milling center, which has the benefit of significantly reducing vibration interference and noise levels, and improving processing stability and product quality.

[0008] Preferably, a plurality of reinforcing plates with right-angled triangle structures are provided on the gantry stand, and two right-angled sides of the reinforcing plates are respectively fixedly connected to the gantry stand and the jig bottom plate.

[0009] By adopting the above technical solution, the reinforcement plate adopts a right-angled triangle structure, which can form a high-rigidity connection between the gantry frame and the jig base plate, thereby significantly improving the overall structural stability; this design not only improves the processing accuracy, but also reduces the resonance phenomenon caused by vibration by enhancing the rigidity of the structure, further reducing mechanical noise and vibration interference; this improvement helps to create a quieter processing environment.

[0011] By adopting the above-mentioned technical scheme, the clamp base plate can be accurately moved along the set first limit track by electrically driving and controlling the first drive motor of the first screw rod; the design of the first limit track and the first limit slider ensures that the clamp base plate can slide freely within a specific range; at the same time, the first limit slider and the adjustment frame effectively prevent the clamp base plate from exceeding the set movement range, thereby realizing accurate position control; as production needs change, the design of the adjustment frame and the clamp base plate enables the clamp base plate to quickly and effectively adjust its position in the X-axis direction to adapt to different workpieces, thereby improving the flexibility of the equipment.

[0012] Preferably, the upper surface of the clamp base plate is provided with a plurality of slots and second threaded holes. When the clamp is slid into the slots of the clamp base plate until the first threaded hole in the clamp is aligned with the second threaded hole, the clamp is installed and fixed on the clamp base plate with the help of the threaded rod in the first threaded hole.

[0013] By adopting the above technical solution, slots are arranged at equal intervals on the fixture base plate, allowing the fixture to be flexibly positioned on the fixture base plate; by passing the fixture through these slots, it can be easily adapted to workpieces of different sizes, thereby achieving rapid warehouse loading and replacement.

[0019] By adopting the above technical solution, linear motion is generated by driving the rotation of the third screw rod; this motion controls the machine head to move up and down in the Z-axis direction through the third limit block; the design of the third limit rail and the third limit slider ensures the limited range of the up and down movement of the control head, thereby ensuring stability and precise position control during the movement.

[0020] Preferably, a lower stop frame is provided on the gantry frame, and the lower stop frame is located directly below the upper stop frame, and a longitudinal limited space is formed between the lower stop frame and the upper stop frame.

[0022] Preferably, the lower lift stop frame and the upper lift stop frame are both provided with channels matching the control machine head, and the cross-sectional dimensions of the channels match the cross-sectional dimensions of the control machine head.

[0024] Preferably, a tool magazine is provided on the control head, and the inclination angle between the tool magazine and the control head is 45°.

[0025] By adopting the above technical solution, compared with the traditional 0°, 60° or 90° tool magazine layout, the 45° angle is more compact in space, reducing the lateral space occupied by the tool magazine; this makes the overall design of the equipment more compact, thereby reducing the demand for space; and the inclined design makes it easier to access the tools in the tool magazine, and there is no need to look up or down when changing the tools, which helps to improve the safety and efficiency of operations.

[0027] 2. Compared with the traditional 0°, 60° or 90° tool magazine layout, the 45° angle is more compact in space and reduces the lateral space occupied by the tool magazine; this makes the overall design of the equipment more compact, thereby reducing the demand for space; and the inclined design makes it easier to access the tools in the tool magazine, and there is no need to look up or down when changing the tools, which helps to improve the safety and efficiency of operations.

[0028] 3.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0031] The present invention discloses a double 45-degree tool magazine 23 arrangement structure type of a double-head drilling and milling center, such as Figure 1 and Figure 2 As shown, the base 1 includes a jig bottom plate 101 and a gantry stand 102 vertically arranged on the upper surface of the jig bottom plate 101, an L-shaped processing area is formed between the jig bottom plate 101 and the gantry stand 102, and an isolation groove 103 is arranged on one side of the gantry stand 102 and extends in a direction perpendicular to the jig bottom plate 101. The isolation groove 103 is a long strip structure. The isolation groove 103 does not completely separate the gantry stand 102, but through the physical isolation and structural optimization, it can effectively isolate and weaken the direct transmission path between the vibrations of each motor, thereby significantly reducing the vibration interference and noise level, improving the processing stability and product quality, and solving the problem that multiple motors will affect each other during the simultaneous vibration inside the base 1, and the vibrations will interfere with each other, which not only aggravates the noise pollution, but also significantly reduces the defects of processing accuracy and product quality.

[0032] like Figure 1 and Figure 2 As shown, specifically, a plurality of reinforcement plates 104 are fixedly installed on the left and right sides of the gantry frame 102. The reinforcement plates 104 are of a right-angled triangle structure, and the two right-angled sides of the reinforcement plates 104 are respectively welded and fixed to the gantry frame 102 and the tool base plate 101. The reinforcement plates 104 adopt a right-angled triangle structure, which can effectively form a strong rigidity connection between the gantry frame 102 and the tool base plate 101, thereby improving the overall structural stability; thereby improving the processing accuracy; by enhancing the rigidity of the structure, reducing the resonance phenomenon caused by vibration, further reducing mechanical noise and vibration interference, and helping to improve the quietness of the processing environment.

[0033] like Figure 3 As shown, an adjusting frame 2 and a fixture base plate 3 are provided on the upper surface of the metallurgical tool base plate 101 and inside the processing area, a first driving motor 4 and two first limiting rails 5 are fixedly installed inside the adjusting frame 2, an output end of the first driving motor 4 is connected to a first screw rod 6, the first screw rod 6 passes through a first limiting block 7 arranged on the lower surface of the fixture base plate 3, a first limiting slider 8 is provided on the lower surface of the fixture base plate 3, and the first limiting slider 8 slides on the first limiting rail 5.

[0034] like Figure 3 As shown, the first drive motor 4 electrically drives and controls the first screw rod 6, so that the clamp base plate 3 can be accurately moved along the set first limit rail 5; the design of the first limit rail 5 and the first limit slider 8 ensures that the clamp base plate 3 can slide freely within a specific range. At the same time, the first limit slider 8 and the adjustment frame 2 can prevent the clamp base plate 3 from moving beyond the set range, thereby achieving accurate position control; as production needs change, the design of the adjustment frame 2 and the clamp base plate 3 allows the position of the clamp base plate 3 to be adjusted quickly and effectively in the X-axis direction to adapt to different workpieces, thereby improving the flexibility of the equipment.

[0035] like Figure 3 As shown, specifically, a plurality of slots 9 with equal spacing are provided on the upper surface of the fixture base plate 3. During installation, the fixture passes through the slots 9 until the first threaded hole in the fixture is aligned with the second threaded hole 10 on the fixture base plate 3, and a mechanical connection is formed by tightening the threaded rod, making full use of the fastening effect of the thread to firmly fix the fixture on the fixture base plate 3; the threaded connection provides a larger contact area, so that the fixture is still stable under high load or vibration environment; with the help of tightening the threaded rod, the fixture is installed and fixed on the fixture base plate 3, specifically; the equally spaced slots 9 provided on the fixture base plate 3 allow the fixture to be flexibly positioned on the fixture base plate 3; by passing the fixture through the slots 9, it is convenient to adapt to workpieces of different sizes, thereby facilitating rapid replacement.

[0036] like Figure 3As shown, a second drive motor 11 and two second limit rails 12 are fixedly mounted on the upper surface of the jig base plate 101, and an output end of the second drive motor 11 is connected to a second screw rod 13, which passes through a second limit block arranged on the lower surface of the adjusting frame 2. A second limit slider 14 is provided at the bottom of the adjusting frame 2, and the second limit slider 14 slides on the second limit rail 12.

[0037] like Figure 3 As shown, the second drive motor 11 provides power to drive the second screw rod 13 to rotate, and the linear displacement generated by the rotation enables the adjustment frame 2 to move within a set range; the second limit slider 14 cooperates with the second limit rail 12 to ensure that the adjustment frame 2 moves along a fixed direction and range; the sliding of the second limit slider 14 in the second limit rail 12 effectively adjusts the position of the adjustment frame 2 in the Y-axis direction to ensure stability and accuracy.

[0038] like Figure 4 and Figure 5 As shown, an upper stop frame 15 is fixedly installed on the top of the gantry frame 102, and the upper stop frame 15 is fixed on the top of the gantry frame 102 to provide sufficient supporting force and stability; two upper stop frames 15 are provided, and the two upper stop frames 15 are detachably arranged between the gantry frame 102, and the detachable design of the two upper stop frames 15 allows the user to quickly maintain or replace them when necessary; a third drive motor 16 and two third limit rails 17 are fixedly installed inside the upper stop frame 15, and a control head 18 is provided inside the upper stop frame 15 for sliding upward along the Z axis, and a third screw rod 19 is connected to the output end of the third drive motor 16, and the third screw rod 19 passes through a third limit block arranged on the control head 18, and a third limit slider 20 is provided on one side of the control head 18, and the third limit slider 20 slides on the third limit rail 17.

[0039] like Figure 4 and Figure 5As shown, the third drive motor 16 serves as a power source to drive the rotation of the third screw rod 19; the rotation of the third screw rod 19 generates linear motion, and the control head 18 is displaced up and down along the Z axis through the third limit block; the setting of the third limit rail 17 and the third limit slider 20 provides a limited range for the up and down movement of the control head 18, ensuring the stability and precise position control of the control head 18 during the movement; the third limit slider 20 slides in the third limit rail 17 to control the position of the control head 18 to avoid accidental movement; the sliding of the control head 18 makes it possible to accurately position it on the Z axis, thereby adapting to different processing requirements; the combination of the third screw rod 19 and the third limit block realizes the conversion between power and displacement, and provides effective and reliable motion control; therefore, through the combination of the third drive motor 16 and the third screw rod 19, high-precision control head 18 movement can be achieved, which helps to improve the processing accuracy and repeatability, and ensure the quality of the final product.

[0040] like Figure 4 and Figure 5 As shown, a lower stop frame 21 is fixedly installed on the gantry frame 102, and the lower stop frame 21 is located just below the upper stop frame 15. A longitudinal limiting space is formed between the lower stop frame 21 and the upper stop frame 15, which is used to limit the up and down lifting of the control head 18. It can not only limit the vertical movement range of the control head 18 to ensure that the up and down lifting of the control head 18 during operation does not exceed the preset limit; but also enhance the overall stability of the gantry frame 102 to avoid the situation where the control head 18 deviates from the expected track during use; by limiting the lifting range of the control head 18, the risk of accidents caused by equipment failure or improper operation is reduced.

[0041] like Figure 4 and Figure 5 As shown, the lower stop frame 21 and the upper stop frame 15 are both provided with a channel 22 matching the control head 18, and the cross-sectional size of the channel 22 matches the cross-sectional size of the control head 18. During the lifting and lowering process of the control head 18, the channel 22 of the lower stop frame 21 and the upper stop frame 15 can effectively guide the movement of the control head 18 to ensure that it maintains a stable and smooth trajectory during lifting and lowering; specifically: the cross-sectional size of the channel 22 matches the cross-sectional size of the control head 18, so that the design can ensure that the control head 18 can accurately move in the channel 22 at any position to avoid swinging or shaking caused by excessive gap; the inner walls of the channel 22 of the lower stop frame 21 and the upper stop frame 15 are sprayed with lubricating oil to reduce the friction resistance generated by the control head 18 during the lifting and lowering process, thereby improving the lifting efficiency and reducing energy consumption and mechanical wear.

[0042] like Figure 4 and Figure 5As shown, specifically, a tool magazine 23 is provided on the control head 18. The tool magazine 23 is a system for storing various tools. The tools can be quickly replaced according to processing needs to improve processing efficiency. The inclination angle between the tool magazine 23 and the control head 18 is 45°. As the inclination angle of the tool magazine 23 increases, the area required for the base 1 can be reduced. Traditionally, if the tool magazine 23 is installed horizontally, the base 1 requires a larger area to accommodate the tool magazine 23, thereby increasing the volume and processing cost of the equipment. At the same time, the angle design can also ensure that the center of gravity of the tool magazine 23 remains within a reasonable range, thereby ensuring stability. Compared with the traditional 0°, 60° or 90° tool magazine 23 layout, the 45° angle is more compact in space, reducing the lateral space occupied by the tool magazine 23. This makes the overall design of the equipment more compact, thereby reducing the demand for space. Moreover, the inclined design makes it easier to access the tools in the tool magazine 23, and there is no need to look up or down when replacing the tools, which helps to improve the safety and efficiency of the operation.

[0043] Working principle: When in use, the operator first fixes the workpiece on the fixture, and then uses the first drive motor 4 to electrically drive and control the first screw rod 6 to adjust the workpiece on the fixture in the X-axis direction; uses the second drive motor 11 to electrically drive and control the second screw rod 13 to adjust the workpiece on the fixture in the Y-axis direction; adjust the workpiece to a suitable position in the X-axis and Y-axis directions.

[0044] The third screw rod 19 is driven and controlled by the third driving motor 16 so that the tool magazine 23 on the machine head 18 is controlled to move along the Z-axis direction until the tool magazine 23 contacts the workpiece to complete the drilling and milling action.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
