Description

Technical Field

[0001] The utility model relates to the technical field of multi-axis drilling for mechanical manufacturing, and more specifically, it relates to a multi-axis drilling machine for mechanical manufacturing. Background Technique

[0002] In the existing field of mechanical manufacturing, a multi-axis drilling machine is a commonly used device for performing drilling operations on workpieces. However, there is a significant problem in the use of this device: when the drilling force is too large, the drill bit will be damaged. This kind of damage not only affects the quality and accuracy of drilling, but also may pose a threat to the safety of operators. First of all, when the drilling force exceeds the bearing range of the drill bit, the drill bit may break, deform or wear, thus affecting the smooth progress of drilling. This will not only lead to a decline in drilling quality, but also may cause damage to the workpiece, increasing production costs and maintenance costs.

[0003] Secondly, the damage of the drill bit may also cause safety accidents. During the drilling process, if the drill bit suddenly breaks or falls off, it may splash out high-speed moving fragments and cause harm to the operator. In addition, the damaged drill bit may also cause the drilling position to shift, affecting the overall quality and performance of the workpiece. Content of the Utility Model

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a multi-axis drilling machine for mechanical manufacturing, which has the following beneficial effects:

[0017] 1. The design of the connecting mechanism enables the multi-axis drilling machine to flexibly install and adjust the position of the drill bit. This design not only improves the safety of drilling but also enhances the convenience of replacing the drill bit of the equipment, enabling it to handle workpieces of different sizes and shapes.

[0018] 2. The clamping mechanism realizes the precise control of the clamping force of the drill bit through the sliding connection of the shrinkage sleeve and the slider, and the action of the compression spring and the pressing plate. When the drill bit is subjected to an excessive torque, the elastic force of the compression spring can cause the clamping between the pressing plate and the insertion rod to be released, thereby avoiding the damage of the drill bit. In addition, through the cooperation of the adjusting sleeve and the push spring, the tightness of the clamping can be conveniently adjusted, ensuring the stability and safety of the drill bit during the drilling process.

[0029] Please refer to Figures 1-5, A multi-axis drilling machine for mechanical manufacturing, including a fixing frame 1, the fixing frame 1 is installed on an external device, a connecting mechanism is arranged on the fixing frame 1, the connecting mechanism includes a moving mechanism, a rotating rod 2, a fixing sleeve 3, a drill bit 4, an inserting rod 5, a clamping mechanism, a compression spring 6, a pressing plate 7 and a counteracting bolt 8. The moving mechanism is connected to the fixing frame 1 and the rotating rod 2 in a matching manner. The fixing sleeve 3 is installed on the rotating rod 2, the drill bit 4 is installed on the inserting rod 5, the clamping mechanism is connected to the fixing sleeve 3 and the compression spring 6 in a matching manner. The pressing plate 7 is installed on the compression spring 6, the pressing plate 7 fits on the side wall of the inserting rod 5, a threaded hole 9 is opened on the pressing plate 7, the counteracting bolt 8 is threadedly connected in the threaded hole 9, a concentric rod 10 is arranged in the fixing sleeve 3, an inserting hole 11 is opened in the inserting rod 5, and the concentric rod 10 is inserted into the inserting hole 11. The clamping mechanism includes a shrinkage sleeve 12 and a slider 13. The shrinkage sleeve 12 is installed in the fixing sleeve 3, the slider 13 is slidably connected in the shrinkage sleeve 12, the compression spring 6 is connected to the slider 13, an adjusting sleeve 14 is threadedly arranged on the fixing sleeve 3, a thrust bearing 15 is slidably arranged in the fixing sleeve 3, the thrust bearing 15 abuts against the adjusting sleeve 14, there are multiple sliders 13, and push springs 16 are respectively arranged on the multiple sliders 13, and the multiple push springs 16 abut against the thrust bearing 15. A hexagonal groove 17 is opened on the adjusting sleeve 14, and a hexagonal sleeve 18 is arranged on the fixing sleeve 3. The moving mechanism includes an adjusting frame 19 and a telescopic universal joint 20. The adjusting frame 19 is connected to the fixing frame 1 in a matching manner, the rotating rod 2 is rotatably connected to the adjusting frame 19, the telescopic universal joint 20 is connected to the rotating rod 2, and a motor 21 is arranged on the fixing frame 1, and the extending end of the motor 21 is connected to the telescopic universal joint 20.

[0030] In this embodiment, when it is necessary to adjust the clamping force of the drill bit 4, first insert the inserting rod 5 into the fixing sleeve 3, then insert the concentric rod 10 into the inserting hole 11. By rotating the adjusting sleeve 14, the thrust bearing 15 can be driven to press on the push spring 16, and then under the action of the push spring 16, multiple sliders 13 will be driven to contract reversely along the shrinkage sleeve 12 towards the concentric rod 10, and then the pressing plate 7 will press on the inserting rod 5. Since both ends of the compression spring 6 are respectively connected to the slider 13 and the pressing plate 7, when the torque of the drill bit 4 exceeds the elastic force of multiple compression springs 6, the connection between the pressing plate 7 and the inserting rod 5 will be disconnected, thus avoiding damage to the drill bit 4 caused by excessive torque.

[0031] More specifically, when it is necessary to limit the adjustment range of the compression spring 6, first select counteracting bolts 8 of different lengths, threadedly and fixedly connect the counteracting bolts 8 in the threaded holes 9 to make the counteracting bolts 8 and the pressing plate 7 in a fixed state. When the compression spring 6 expands and contracts to make the counteracting bolts 8 abut against the sliders 13, the movement of the pressing plate 7 is restricted, thus completing the adjustment of the clamping force, and then the corresponding drilling process is carried out through drilling.

[0032] In summary, when the overall equipment is in use or running: when it is necessary to adjust the clamping force of the drill bit 4, first insert the insertion rod 5 into the fixed sleeve 3, and then insert the concentric rod 10 into the insertion hole 11, and by rotating the adjusting sleeve 14, the thrust bearing 15 can be driven to press on the push spring 16, and then under the action of the push spring 16, multiple sliders 13 will be driven along the shrinking sleeve 12 to shrink in the opposite direction toward the concentric rod 10, and then the pressure plate 7 will be pressed on the insertion rod 5. Since the two ends of the compression spring 6 are respectively connected to the slider 13 and the pressure plate 7, when the torque of the drill bit 4 exceeds the elastic force of the multiple compression springs 6, the clamping between the pressure plate 7 and the insertion rod 5 will be released, thereby avoiding damage to the drill bit 4 caused by excessive torque.

[0033] When it is necessary to limit the adjustment range of the compression spring 6, first select interference bolts 8 of different lengths, and thread the interference bolts 8 into the threaded hole 9 so that the interference bolts 8 and the pressure plate 7 are in a fixed state. When the compression spring 6 is extended or contracted so that the interference bolts 8 press against the slider 13, the movement of the pressure plate 7 is limited, thereby completing the adjustment of the clamping force, and then the corresponding drilling process is performed by drilling.

[0034] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
