Description

Technical Field

[0001] The utility model belongs to the technical field of processing tooling, and particularly relates to a tooling with an interchangeable boring head. Background Art

[0002] In the field of machining, deep hole boring, as a key technology, is widely used in multiple industries such as aerospace, automotive manufacturing, and precision instruments. However, for a long time, traditional deep hole boring machines have faced significant limitations.

[0003] Poor compatibility of boring heads: The design of traditional deep hole boring machines often adapts based on specific boring head models, and it is difficult to interchange different models of boring heads. This means that whenever it is necessary to process workpieces of different specifications or materials, enterprises may need to replace the entire machine tool or carry out complex adjustments, greatly limiting the flexibility of processing.

[0004] High equipment investment cost: Since each processing task may require a specific combination of machine tool and boring head, enterprises have to invest a large amount of funds to purchase multiple models of machine tools to meet diverse production needs. This not only increases the initial equipment investment cost but also occupies valuable production space.

[0005] Low equipment utilization rate: In most cases, a single machine tool can only process specific types of workpieces, resulting in the inability to perform other types of processing tasks on this machine tool. This low utilization rate not only wastes equipment resources but also reduces the overall production efficiency. Content of the Utility Model

[0006] The utility model provides a tooling with an interchangeable boring head, aiming to solve the problems that due to the fixed and difficult-to-interchange boring head models of traditional deep hole boring machines, the burden of equipment investment is increased and a large amount of production space is occupied. At the same time, this design also limits the processing range of a single machine tool, resulting in the machine tool being able to process only specific types of workpieces most of the time, causing resource waste and a reduction in overall production efficiency.

[0007] The utility model is realized as follows: A tooling with an interchangeable boring head includes a boring bar. Two opposite ends of the boring bar are respectively provided with a first limiting cavity and a second limiting cavity, and the first limiting cavity and the second limiting cavity are on the same axis. Two boring heads are arranged in the first limiting cavity and the second limiting cavity. A locking mechanism is arranged on one side of the first limiting cavity and the second limiting cavity away from their open ends. Among them, the locking mechanism includes: a locking groove, which is arranged at the internal position corresponding to the first limiting cavity and the second limiting cavity; the locking groove is annularly arranged; several shock-absorbing springs are arranged in the locking groove; dampers are integrated in several of the shock-absorbing springs; and locking protrusions are arranged on one side of several of the shock-absorbing springs away from the corresponding locking grooves.

[0008] Preferably, an outer surface of the boring head is provided with an outer spiral groove, and inner walls of the first limiting cavity and the second limiting cavity are both provided with an inner spiral groove.

[0009] Preferably, the winding ratio of the two external threads is consistent with the winding ratio of the corresponding internal threads.

[0010] Preferably, locking recesses are provided on the end sides of the two boring heads, and the inner diameter of the locking recesses matches the outer diameter of the locking protrusions.

[0011] Preferably, a group of first positioning holes are formed through the side wall of the boring bar, and corresponding second positioning holes are formed on the side wall of the boring head.

[0012] Preferably, detection sensors are provided in both the first limiting cavity and the second limiting cavity, and the detection sensors are electrically connected to the locking mechanism.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] First, the boring bar of this device can be flexibly interchanged to install different types of boring heads, which greatly enhances the flexibility of the processing process. Traditionally, a single boring machine is limited to processing only fixed models of products, but this design breaks this limitation, allowing a boring machine to easily adapt to a variety of processing tasks without the need to purchase new machine tools. This flexibility not only reduces the company's operating costs, but also improves equipment utilization and processing efficiency. Both ends of the tooling are designed to adapt to the connection types of the two boring machines, and through precise hole-shaft matching, thread pre-tightening and high concentricity design, seamless connection with different types of deep hole boring machines is ensured. This universal design enables the tooling to be widely used in a variety of processing environments, reducing the troubles and costs caused by equipment incompatibility.

[0015] Second: The locking mechanism of this device ensures the stability of the boring head during the processing, reduces the processing errors caused by looseness or deviation, ensures that the processed products have excellent straightness, roundness and surface roughness, and meets the needs of high-precision processing; the application of shock-absorbing springs and dampers not only improves the processing accuracy, but also enhances the stability of the tooling, prevents equipment damage or processing failure due to excessive vibration. In addition, the introduction of detection sensors provides real-time safety protection for the processing process. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the description of the present application in the specification are only for the purpose of describing specific embodiments, and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects, not to describe a specific order.

[0022] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] An embodiment of the utility model provides a tooling with interchangeable boring heads, as Figures 1-4 shown, including a boring bar 1; two end heads of the boring bar 1 arranged back to back are respectively provided with a first limiting cavity 2 and a second limiting cavity 3, and the first limiting cavity 2 and the second limiting cavity 3 are on the same axis; two boring heads 4 arranged in the first limiting cavity 2 and the second limiting cavity 3; locking mechanisms are arranged on one side of the first limiting cavity 2 and the second limiting cavity 3 far from their open ends; wherein, the locking mechanism includes: a locking groove 5, and the locking groove 5 is arranged at an internal position corresponding to the first limiting cavity 2 and the second limiting cavity 3; the locking groove 5 is arranged in a ring shape; a plurality of shock-absorbing springs 6 arranged in the locking groove 5; dampers are integrated in a plurality of the shock-absorbing springs 6; a locking convex block 7 is arranged on one side of a plurality of the shock-absorbing springs 6 far from the corresponding locking groove 5.

[0024] It should be noted that, due to the fixed model and difficult interchangeability of the boring head 4 in traditional deep-hole boring machines, the burden of equipment investment is increased, and a large amount of production space is occupied. At the same time, this design also limits the processing range of a single machine tool, resulting in the equipment being able to process only specific types of workpieces for most of the time, causing waste of resources and a reduction in overall production efficiency. In this solution, by flexibly interchanging the boring head 4, the device can handle diverse processing tasks, reduce operating costs, and improve equipment utilization and processing efficiency. At the same time, the precise locking mechanism jointly ensures high precision, high stability, and safety during the processing, reduces processing errors, improves product quality, and effectively prevents production accidents caused by vibration or equipment failures.

[0025] Specifically, in this embodiment, this solution mainly includes a boring bar 1. The boring bar 1 has two oppositely arranged ends, which are respectively internally provided with a first limiting cavity 2 and a second limiting cavity 3. The two share the same axis line and are specially designed for installing and stabilizing the boring head 4. These two limiting cavities can flexibly interchange and install the corresponding boring head 4 according to different processing tasks.

[0026] A locking groove 5 is designed inside each limiting cavity to accommodate the locking element. A number of shock-absorbing springs 6 are integrated in the locking groove 5, and dampers are also embedded inside the shock-absorbing springs 6. The two work together to effectively absorb the vibration and impact generated during processing, significantly improving the overall stability of the tooling and the processing accuracy.

[0027] When the boring head 4 is accurately placed in the corresponding limiting cavity and perfectly aligned with the axis line, the locking mechanism is immediately activated. At this time, the shock-absorbing springs 6 and the dampers are compressed, pushing the locking protrusions 7 to expand outwards until they closely fit with specific parts of the boring head 4, achieving the stable locking of the boring head 4. By finely adjusting the locking mechanism, it can be ensured that the locking protrusions 7 apply just the right locking force to prevent the boring head 4 from loosening or falling off during processing.

[0028] As the processing progresses, the boring bar 1 drives the boring head 4 to perform rotational and feeding actions to accurately process the workpiece. During this process, the shock-absorbing springs 6 and the dampers continue to play a role, effectively suppressing vibration and impact, maintaining the stable state of the tooling, and ensuring the achievement of processing accuracy. At the same time, the locking mechanism ensures that the correct relative position is maintained between the boring head 4 and the workpiece, avoiding the generation of any processing errors.

[0029] If it is necessary to replace the boring head 4 to meet different processing requirements, the operation is also simple and efficient. First, unlock the locking mechanism to release the locking force of the locking lug 7 and retract it to its initial position. Then, easily remove the old boring head 4 and accurately place the new boring head 4 into the limiting cavity. Finally, adjust the locking mechanism again until the locking lug 7 is in close contact with the new boring head 4, completing the quick replacement of the boring head 4. The entire process is reasonably designed and easy to operate, ensuring continuous improvement of processing efficiency.

[0030] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, an external spiral groove 8 is provided on the outer surface of the boring head 4, and internal spiral grooves 9 are provided on the inner walls of both the first limiting cavity 2 and the second limiting cavity 3.

[0031] In this embodiment, when the boring head 4 is placed in the limiting cavity, the external spiral groove 8 and the internal spiral groove 9 engage with each other. By rotating the boring head 4, the boring head 4 can be gradually locked in the limiting cavity. This spiral locking method not only ensures the stability of the boring head 4 during processing but also facilitates the quick replacement of the boring head 4 when needed.

[0032] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the winding ratios of the two external threads are the same as those of the corresponding internal threads.

[0033] In this embodiment, it is ensured that the two can engage smoothly with each other, reducing friction and resistance caused by non - matching. At the same time, it helps to enhance the locking force between the threads, making the boring head 4 more stable during processing and not prone to loosening or falling off.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, locking concave blocks 10 are provided on the end sides of both boring heads 4, and the inner diameter dimension of the locking concave block 10 is in line with the outer diameter dimension of the locking lug 7.

[0035] In this embodiment, through the close cooperation between the locking lug 7 and the locking concave block 10, the boring head 4 can maintain higher stability during processing, reducing loosening or deviation caused by vibration or impact.

[0036] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, a set of first positioning holes 11 are penetrated through the side wall of the boring bar 1, and corresponding second positioning holes are provided on the side wall of the boring head 4.

[0037] In this embodiment, in addition to the spiral locking and locking mechanism, the positioning holes also provide additional fixing points. The design of the first positioning hole 11 and the second positioning hole allows the use of positioning pins, bolts or other fasteners to accurately align and fix the relative position between the boring head 4 and the boring bar 1, which helps to reduce the machining errors caused by improper installation, thereby enhancing the stability of the boring head 4 during the machining process. This helps to prevent the boring head 4 from shifting or loosening during high-speed rotation or under large cutting forces.

[0038] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, detection sensors 12 are provided in both the first limiting cavity 2 and the second limiting cavity 3, and the detection sensors 12 are electrically connected to the locking mechanism.

[0039] In this embodiment, the detection sensor 12 (RX-S) can real-time monitor the position of the boring head 4 in the first limiting cavity 2 and the second limiting cavity 3, ensuring that it maintains the correct position and posture during the machining process, which helps to reduce the machining errors caused by position deviation.

[0040] Working principle: The boring bar 1 of this device has two oppositely arranged ends, which are respectively internally provided with a first limiting cavity 2 and a second limiting cavity 3. These two cavities share the same axis. Such a design enables the boring bar 1 to flexibly and interchangeably install the corresponding boring head 4 according to the requirements of different machining tasks; inside each limiting cavity, a locking groove 5 is specially designed, and a shock-absorbing spring 6 and a damper are integrated in this groove; this pair of combinations work together during the machining process to effectively absorb vibrations and impacts, significantly improving the overall stability and machining accuracy of the tooling;

[0041] After the boring head 4 is placed in the limiting cavity and aligned with the axis, by rotating the boring head 4, its gradual locking in the limiting cavity can be achieved. This spiral locking method not only ensures the stability of the machining, but also facilitates the quick replacement of the boring head 4 when needed; at this time, the shock-absorbing spring 6 and the damper are compressed, pushing the locking protrusions 7 to expand outwards until they closely fit with the locking recesses 10 on the boring head 4 to achieve a firm lock; by finely adjusting the locking mechanism, it can be ensured that the locking force is just right to prevent the boring head 4 from loosening or falling off during the machining process; at the same time, the design of the first positioning hole 11 and the second positioning hole provides additional fixing points between the boring head 4 and the boring bar 1, and the use of fasteners such as positioning pins and bolts can accurately align and fix their relative positions, reducing the machining errors caused by improper installation;

[0042] During the machining process, the boring bar 1 drives the boring head 4 to perform rotational and feeding actions to precisely machine the workpiece. At this time, the shock-absorbing spring 6 and the damper continuously play their roles, effectively suppressing vibrations and impacts, maintaining the stable state of the tooling, and ensuring the achievement of machining accuracy. The double guarantee of the locking mechanism and screw locking ensures that the correct relative position is maintained between the boring head 4 and the workpiece, avoiding the occurrence of any machining errors. To further improve safety, a detection sensor 12 is also provided inside the boring bar 1. The detection sensor 12 can monitor the position of the boring head 4 and the state of the locking mechanism in real time. Once an abnormal position of the boring head 4 or the failure of the locking mechanism is detected, the detection sensor 12 immediately sends a signal to trigger the emergency stop mechanism, quickly stopping the machining process to prevent accidents from occurring.
