[0019] The embodiments of the present invention will be described below with reference to the accompanying drawings.
[0020] Embodiment: A composite drilling device for improving the efficiency of deep hole processing of aluminum alloy, such as Figure 1 and Figure 2 As shown, it includes a drilling machine 1, a material rack 2, a gantry 3, a cylinder 4, a fixing plate 5, a control button 6 and a fixing component. Two cylindrical material racks 2 are placed at the right end of the drilling machine 1. The bottom of the gantry 3 is fixed to the front and rear sides of the right end of the drilling machine 1 by bolts. The top of the cylinder 4 is welded to the top of the gantry 3. The fixing plate 5 is welded to the bottom of the telescopic rod of the cylinder 4. A control button 6 is arranged at the front end of the gantry 3, and the control button 6 is connected to the cylinder 4 by wire. A fixing component for assisting in fixing the aluminum rod to be processed is arranged at the bottom of the fixing plate 5.
[0021] like Figure 3As shown, the fixed assembly includes a bracket 7, a swing block 8 and a torsion spring 9. Four brackets 7 are welded to the bottom of the fixed plate 5, two in a group, and are located on the quadrilaterals at the front and rear ends of the fixed plate 5. The swing block 8 is rotatably connected to the bottom of the bracket 7 through a round rod. The torsion spring 9 is sleeved on the left and right ends of the round rod and is fixed to the bracket 7 and the swing block 8 respectively.
[0022] The staff places the aluminum rod to be processed between the two material racks 2. Since a groove is formed between the two material racks 2, the aluminum rod will not move left and right. Then, the cylinder 4 is turned on by the control button 6 to push the fixed plate 5 to move downward. When the swing block 8 contacts the aluminum rod, it continues to move downward. Then, the swing block 8 rotates according to the curvature of the surface of the aluminum rod, twisting the torsion spring 9, and the cylinder 4 can detect the pressure uploaded from the bottom. After reaching the threshold, the cylinder 4 is closed, thereby ensuring the fixing effect of the aluminum rod without causing damage to the surface of the aluminum rod. Through the cooperation of the four rotatable swing blocks 8 and the two material racks 2, the fixed contact area is increased and the fixing effect is optimized, thereby ensuring safety and processing efficiency. Then, the drilling machine 1 is turned on to drill the aluminum rod. After the processing is completed, the drilling machine 1 is turned off, and the cylinder 4 is turned on to move the fixed plate 5 upward. Therefore, under the action of the torsion spring 9, the swing block 8 is reset to maintain the vertical state, the cylinder 4 is turned off, the aluminum rod is removed, and the drilling is completed.
[0023] like Figure 4 As shown, an anti-skid pad 14 is also included, and an anti-skid pad 14 is placed on the upper surface of the material rack 2.
[0024] like Figure 3 As shown, a rubber pad 10 is also included, and the rubber pad 10 is welded to the bottom of the swing block 8.
[0025] By using the anti-slip pad 14 and the rubber pad 10, the contact area between the fixing component and the aluminum rod can be further increased when fixing the aluminum rod, thereby further improving the fixing effect and improving the safety of the processing process while keeping the pressure unchanged.
[0026] like Figure 4 As shown, it also includes a feed support platform 11 and a roller 12 . The feed support platform 11 is connected to the right end of the drilling machine 1 , and a plurality of rollers 12 are arranged on the feed support platform 11 .
[0027] like Figure 4 As shown, a buffer pad 13 is also included, and each of the rollers 12 is sleeved with a buffer pad 13 .
[0028] For aluminum bars with longer lengths, the rear end can be placed on the feed support platform 11. During the loading and unloading process, the movement of the rollers 12 can save effort, thereby optimizing the processing process and reducing processing consumption. A buffer pad 13 is sleeved on the rollers 12 to also protect the outer surface of the aluminum bars.
[0029] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
