Description

Technical Field

[0001] This utility model relates to the field of drilling and boring machine tool technology, specifically a mechanism that can realize drilling, boring, and automatic diameter change without changing tools. Background Technology

[0002] A drilling and boring machine is a machine tool specifically designed for machining the internal holes and external diameters of workpieces. It consists of a spindle, cutting tools, and a feed mechanism. The main cutting tools used are drill bits and boring tools. Drill bits are primarily used for machining small holes of a fixed diameter, while boring tools are mainly used for machining large-diameter or high-precision holes.

[0003] To perform drilling and boring functions on a part, the usual method is to first drill a hole with a twist drill, then switch to a boring tool and bore the hole to the required diameter. In this case, to perform drilling and boring functions simultaneously, different tools must be switched. Therefore, further improvements can be made. Utility Model Content

The tool adjusting mechanism includes an upper connector and a lower connector that are connected to each other, and a mounting plate. A fixing ring is fixedly installed inside the right side of the lower connector, and a locking block is fixedly installed on the fixing ring by bolts. A trapezoidal screw is inserted into the top of the lower connector. A bushing is sleeved on the right end of the trapezoidal screw, and a spring is sleeved on the outer side of the right end of the trapezoidal screw. A mating sleeve is fixedly installed on the left end of the trapezoidal screw, and the mating sleeve transmits torque through a key. An elastic retaining ring is fixedly installed at the end of the trapezoidal screw. A compression spring is fixedly installed between the fixing ring and the mating sleeve, and the compression spring is sleeved on the outer side of the left end of the trapezoidal screw. A servo motor is fixedly installed on the left side of the mounting plate, and a mating male sleeve is fixedly installed at the end of the spindle of the servo motor. The mating male sleeve and the mating female sleeve are connected by a convex-concave fit. A servo electric cylinder is also fixedly installed on the top of the mounting plate.

[0005] As an optimization, the mating sleeve is locked and fixed on the end of the servo motor spindle by a set bolt, and the torque is transmitted by a key.

[0006] As an optimization, the servo motor is fixedly mounted on the left side of the mounting plate by bolts.

[0007] As an optimization, the servo electric cylinder is fixedly mounted on the top of the mounting plate by a pin.

[0018] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 A mechanism for automatic diameter adjustment of drills and boring tools without tool changing is disclosed. The mechanism includes a tool adjusting mechanism comprising an upper connector 1 and a lower connector 2 that are connected to each other, and a mounting plate 13. A fixing ring 3 is fixedly installed inside the right side of the lower connector 2, and a locking block 7 is fixedly installed on the fixing ring 3 by bolts. A trapezoidal screw 4 is inserted into the top of the lower connector 2. A bushing 5 is sleeved on the right end of the trapezoidal screw 4, and a spring 6 is sleeved on the outer side of the right end of the trapezoidal screw 4. A mating sleeve 8 is fixedly installed on the left end of the trapezoidal screw 4, and the mating sleeve 8 transmits torque via a key. An elastic retaining ring is fixedly installed at the end of the trapezoidal screw 4, and a compression spring is fixedly installed between the fixing ring 3 and the mating sleeve 8. Spring 9, and compression spring 9 is sleeved on the outer side of the left end of trapezoidal screw 4. Servo motor 11 is fixedly installed on the left side of mounting plate 13. Servo motor 11 is fixedly installed on the left side of mounting plate 13 by bolts. Male sleeve 10 is fixedly installed on the end of spindle of servo motor 11. Male sleeve 10 is locked and fixed on the end of spindle of servo motor 11 by set bolts and torque is transmitted by key. Male sleeve 10 and female sleeve 8 are connected by a convex-concave fit. Servo cylinder 12 is also fixedly installed on the top of mounting plate 13. Servo cylinder 12 is fixedly installed on the top of mounting plate 13 by pins. Servo cylinder 12 is used to drive servo motor 11 forward or backward.

[0021] Please see Figure 1-3 The bottom of the lower connector 2 has an interface 14, and a tool 15 is installed inside the interface 14. The tool 15 is a flat-shank tool and is installed in the interface 14 at the bottom of the lower connector 2 by screw pressing. The tool 15 is a single-edged indexable rotary head.

[0022] In use, the servo electric cylinder 12 drives the servo motor 11 forward, so that the male sleeve 10 and the female sleeve 8 are coupled together. After the coupling, the servo motor 11 drives the trapezoidal screw 4 to rotate, which causes the lower connector 2 to shift along the axis, thus realizing the automatic diameter change operation.

[0023] When the axis offset distance reaches the requirement, the servo motor 11 is stopped and the servo cylinder 12 is controlled to drive the servo motor 11 to move backward, which will cause the male sleeve 10 and the female sleeve 8 to separate. After the male sleeve 10 and the female sleeve 8 separate, the female sleeve 8 is automatically locked by the locking block 7, which will restrict the rotation of the female sleeve 8, thereby ensuring the accuracy of the offset distance. The locking block 7 remains locked during the boring process.

[0024] When the next diameter change is required, the docking and disengagement process is repeated. During the docking process and when adjusting the axis offset distance, locking block 7 will automatically open, and when docking and disengaging, locking block 7 will automatically lock.

[0025] In summary, this mechanism, which enables drilling and boring without tool changing and automatic diameter changing, can achieve automatic diameter changing by remotely and automatically controlling the tool adjustment mechanism to offset the axis of the tool 15. At this time, boring can begin without manual tool adjustment to change the diameter of the boring tool, and drilling and boring can be performed without changing the tool.
