The boring die mechanism has an initial state in which the boring structure 30 is mounted on the bracket 20 and a use state in which the boring structure 30 is inserted through the boring die holder 40 to bore the workpiece 60 to be processed.

And the flexible characteristic of the machining center is exerted, and the quick production replacement can be realized by replacing the boring structure 30. In addition, the rod penetrating process of the boring structure 30 can be realized through programming, so that the risk of collision caused by manual operation is reduced. Meanwhile, the boring die mechanism has larger expandability, and the machining of other process contents, such as end face milling, side face machining and the like, can be added on the basis of the original boring process by using a machining center instead of a special machine tool, so that the machining consistency is improved by clamping multiple processes at one time.
As shown in fig. 1, 3-5, the boring die mechanism further includes a tray 80 and a control module. The tray 80 is liftably disposed on the base 10 for supporting the workpiece 60 to be processed. The control module is electrically connected to the tray 80. Wherein, in the process that the tray 80 supports the workpiece 60 to be processed, when the bottom surface of the workpiece 60 to be processed contacts with the supporting surface, the workpiece 60 to be processed is supported by the supporting surface, and the control module controls the tray 80 to move to a position avoiding the fixing assembly 50. In this way, before the fixing component 50 fixes the workpiece 60 to be processed, the workpiece 60 to be processed is placed on the tray 80, so that the workpiece 60 to be processed is driven to descend by the tray 80 until the bottom surface of the workpiece 60 to be processed contacts with the supporting surface, and the workpiece 60 to be processed is fixed and pressed by the fixing component 50.

The pressure detection device is arranged at the other end of the air supply pipeline and is electrically connected with the control module. After the gas is conveyed into the gas detection hole through the gas conveying pipeline, if the detection value of the pressure detection device is greater than or equal to a preset value, the control module controls the first driving device to start, and the first driving device drives the pressing structure 52 to move towards the supporting surface so as to press the workpiece 60 to be processed. In this way, the above-mentioned arrangement of the air detection hole and the pressure detection device can obtain the contact condition between the workpiece 60 to be processed and the supporting surface, when the detection value of the pressure detection device is greater than or equal to the preset value, the workpiece 60 to be processed is judged to be in contact with the supporting surface, and at this time, the first driving device can be controlled to be started so as to compress the workpiece 60 to be processed through the fixing component 50.

Optionally, the first driving means is a motor or a driving cylinder.
In this embodiment, the boring die mechanism further includes a second driving device, and the second driving device is in driving connection with the positioning structure 70 to drive the positioning structure 70 to perform lifting movement. The control module is electrically connected with the second driving device and used for controlling the start-stop state of the second driving device; after the gas is conveyed into the gas detection hole through the gas conveying pipeline, if the detection value of the pressure detection device is larger than or equal to a preset value, the second driving device is controlled to be started through the control module, and the second driving device drives the positioning structure 70 to move towards the workpiece 60 to be processed until the positioning structure 70 is matched with the matching part on the workpiece 60 to be processed. In this way, when the workpiece 60 to be machined is detected to be in contact with the supporting surface, the second driving device is started, and the positioning structure 70 is driven to move upwards through the second driving device until the positioning structure is matched with the matching part of the workpiece 60 to be machined, so that the positioning structure 70 positions the workpiece 60 to be machined, and the workpiece 60 to be machined is subjected to boring action subsequently.
Optionally, the second driving means is a motor or a driving cylinder.

In this way, the above arrangement makes the structure selection of the positioning structure 70 and the matching part more flexible on one hand, so as to meet different use requirements and working conditions, and also improves the processing flexibility of the staff; on the other hand, the number of the positioning structures 70 is more flexible to select so as to meet different use requirements and working conditions.
In this embodiment, the positioning structure 70 is a protrusion, and the mating portion is a recess, and the protrusion can extend into the recess to be in limit fit with the recess, so as to position the workpiece 60 to be processed by the positioning structure 70. The number of the positioning structures 70 is three, two of the three positioning structures 70 are arranged at intervals along the length direction of the workpiece 60 to be processed, and two of the three positioning structures 70 are arranged at intervals along the width direction of the workpiece 60 to be processed.

As shown in fig. 2, the boring jig 40 has a mounting hole 41, the mounting hole 41 includes a circular hole 411 and a key groove 412 communicating with each other, and the boring structure 30 includes the boring bar 31, the key structure 33, and the boring cutter 34. The boring bar 31 comprises a first bar section 311 and a second bar section 312 which are connected with each other, the outer diameter of the first bar section 311 is larger than that of the second bar section 312, and a tool handle 32 is arranged on the end part of the first bar section 311 far away from the second bar section 312. A key structure 33 is provided on the outer peripheral surface of the first pole segment 311 for a positive fit with the key slot 412. The boring cutter 34 is disposed on the outer peripheral surface of the second shaft section 312. In this way, the above arrangement of the key structure 33 and the key slot 412 ensures a non-rotational fit between the boring structure 30 and the boring jig frame 40 in the assembled state. Meanwhile, in the process of assembling the boring structure 30 and the mounting hole 41, the boring cutter 34 is prevented from being damaged due to motion interference between the boring cutter 34 and the mounting hole 41 by the arrangement of the second rod section 312, and the matching area between the boring structure 30 and the mounting hole 41 can be increased by the arrangement of the first rod section 311, so that the assembling stability between the boring structure 30 and the boring die holder 40 is improved.

Thus, during the process of extending the second rod segment 312 into the mounting hole 41, the arrangement further avoids structural interference between the boring cutter 34 and the mounting hole 41 to damage the boring cutter 34, and improves the stability of the fit between the boring structure 30 and the boring jig 40 when the boring structure 30 moves to the first rod segment 311 extending into the mounting hole 41.
As shown in fig. 1 and 3, the boring structure 30 includes a first boring structure 35 for machining a spindle hole and a second boring structure 36 for machining a camshaft hole. Wherein, when the boring die mechanism is in an initial state, the first boring structure 35 and the second boring structure 36 are respectively positioned at two sides of the fixing assembly 50. In this way, the above arrangement promotes the versatility of the boring die mechanism so that the boring die mechanism can process the spindle hole and the cam shaft hole of the workpiece 60 to be processed. Meanwhile, the arrangement ensures that the overall structure layout of the boring die mechanism is more reasonable and compact, and the space utilization rate of the boring die mechanism is improved.
Alternatively, two boring die holders 40 are arranged, the two boring die holders 40 are arranged oppositely, and the fixing assembly 50 is positioned between the two boring die holders 40; and/or the boring die mechanism further comprises an accumulator 90, the accumulator 90 being provided on the base 10 for maintaining the pressing force applied by the pressing structure 52 to the workpiece 60 to be machined. In this way, the above arrangement of the boring die holder 40 increases the mating area between the boring die holder 40 and the boring structure 30, thereby improving the stability of the boring structure 30. The above arrangement of the accumulator 90 ensures that the fixing assembly 50 can continuously compress and fix the workpiece 60 to be processed to enhance the boring accuracy of the boring die mechanism.

The control module controls the second driving device to act so that the positioning structure 70 is lifted and matched with the matching part (pin hole) of the workpiece 60 to be processed, and the fixing assembly 50 presses the workpiece 60 to be processed downwards.
2. Preparation process for working
The machining center spindle reaches the position of the first boring structure 35, and the spindle broaching mechanism acts to fix the tool shank 32 to the machining center spindle. The machining center main shaft drives the first boring structure 35 to move to the boring die holder 40, the first boring structure 35 enters the boring die holder 40 in an eccentric posture, and an avoidance space is formed by utilizing the fact that the outer diameter of the second rod section 312 is smaller than that of the first rod section 311, so that interference between the boring cutter 34 and the workpiece 60 to be machined is avoided, and the boring cutter enters the workpiece 60 to be machined.
3. Boring process

The machining center spindle drives the first boring structure 35 to rotate, and the boring cutter 34 starts machining the workpiece 60 to be machined. After the first boring structure 35 is machined, the machining center spindle places the first boring structure 35 on the support 20, grabs the second boring structure 36, and performs boring machining of the camshaft hole, wherein the action flow is the same as that of machining of the spindle hole.
