Description

Technical Field

[0001] This invention relates to a multifunctional boring machine that can be automatically calibrated, belonging to the technical field of boring machines. Background Technology

[0002] Portable boring machines are mobile devices used for on-site hole machining, widely used in industrial fields, especially in repair and maintenance applications. Unlike traditional stationary boring machines, portable boring machines are lightweight, compact, easy to transport and install, and can machine holes in confined or hard-to-reach spaces.

[0003] Portable boring machines are typically used for repairs, through-hole machining, and routine maintenance of factory equipment in situations where large equipment or structures (such as ships, bridges, or heavy machinery) cannot be disassembled, quickly resolving issues such as wear on equipment holes. However, existing portable boring machines rely on manual positioning during use, and the boring accuracy is affected by vibrations during operation, which can easily lead to misalignment. Therefore, designing a multi-functional boring machine with automatic calibration is crucial. Summary of the Invention

[0004] To address the shortcomings of the prior art, this invention provides a multifunctional boring machine that can be automatically calibrated.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A multi-functional boring machine capable of automatic calibration includes a drive motor. A first component and a second component are sequentially connected to a spindle on one side of the drive motor. A hole measuring module is provided on the spindle. The hole measuring module is connected to the spindle via a detachably connected boring tool. The first component includes a positioning module and several sets of six-bar linkages arranged around the positioning module.

[0006] Furthermore, the positioning module has a universal joint in the middle, and the main shaft passes through the universal joint.

[0007] Furthermore, each of the six-bar linkages includes a guide rod, a rotary encoder, and coils and magnets for two linear motors.

[0008] Furthermore, the coil on one side of the linear motor is rotatably connected to the positioning module, and the magnet on the opposite side is fixed to the outside of the grating displacement sensor by a magnetic bracket.

[0009] Furthermore, one end of the guide rod is rotatably connected to the positioning module via a rotary encoder, and the other end is equipped with a through-connected grating displacement sensor.

[0010] Furthermore, the first component is provided with four sets of six-bar linkage structures.

[0011] Furthermore, the second component has the same structure as the first component and is arranged symmetrically.

[0012] Furthermore, a bridge circuit is provided inside the spindle.

[0013] Furthermore, the spindle is detachably connected to the second component.

[0014] Furthermore, the spindle is provided with several mounting holes that are compatible with the boring tool.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: The six-bar linkage combined with a universal joint controls the entire boring machine in a relatively fixed position. The hole measurement module mounted on the spindle accurately reflects the relative position between the boring machine and the bore, improving the accuracy of boring positioning. Before starting boring, the host computer provides the operator with a comparison before and after boring, allowing the operator to quickly and directly adjust boring parameters via the boring machine. During use, the positioning modules on the first and second components allow for real-time adjustment of the boring tool position, reducing errors caused by vibrations of components and the machine during boring. This avoids the problem of existing portable boring machines relying primarily on manual adjustment for machining accuracy and lacking automatic control during operation, greatly improving boring efficiency and accuracy, resulting in better performance.

[0022] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0023] like Figures 1-5 As shown, the automatically calibrated multi-functional boring machine of this embodiment includes a drive motor 1. A first component 10 and a second component 11 are provided on one side of the drive motor 1 and are connected in sequence through a spindle 4. A hole measuring module 5 is provided on the spindle 4. The hole measuring module 5 is connected to the spindle 4 through a boring tool 6 that can be detachably connected. The first component 10 includes a positioning module 2 and several sets of six-bar linkage structures arranged around the positioning module 2.

[0024] The positioning module 2 has a universal ring 7 in the middle, and the main shaft 4 passes through the universal ring 7.

[0025] Each of the six-bar linkages includes a guide rod 22, a rotary encoder 24, and coils and magnets for two linear motors 21.

[0026] The coil on one side of the linear motor 21 is rotatably connected to the positioning module 2, and the magnet on the opposite side is fixed to the outside of the grating displacement sensor 23 by the magnetic bracket 25.

[0027] One end of the guide rod 22 is rotatably connected to the positioning module 2 via a rotary encoder 24, and the other end is provided with a through-connected grating displacement sensor 23.

[0028] The first component 10 is provided with four sets of six-bar linkages. The coils on one side of adjacent linear motors 21 in adjacent sets of six-bar linkages are rotatably connected to the positioning module 2 through the same connecting shaft.

[0029] The second component 11 has the same structure as the first component 10 and is arranged symmetrically.

[0030] The main spindle 4 is equipped with a bridge circuit. All components on the first assembly 10 and the second assembly 11, the universal joint 7, and the bridge circuit are connected to the host computer.

[0031] The main shaft 4 is detachably connected to the second component 11.

[0032] The spindle 4 is provided with several mounting holes 51 that are adapted to the boring tool 6.

[0033] In use, the second component 11 of the boring machine is first disassembled. After the spindle 4 passes through the hole to be bored, the second component 11 is connected to the spindle 4. The magnetic brackets 25 in each group of six-bar linkages of the first component 10 and the second component 11 are magnetically fixed to the outside of the part being bored. Each group of six-bar linkages on the first component 10 establishes a polar coordinate system through its own grating displacement sensor 23 and rotary encoder 24 to determine the position between the fixed point and the first component 10. The second component 11 works on the same principle. When the position needs to be adjusted, the two linear motors 21 of each group of six-bar linkages act as drive pairs to make the six-bar linkage move up and down, thereby achieving magnetic attraction. The relative position between the bracket 25 and the first component 10 or the second component 11 is adjusted; then the boring tool 6 is inserted into the mounting hole 51, and the position of the boring tool 6 relative to the positioning module 2 on the first component 10 and the second component 11 is positioned by the bridge circuit placed in the spindle 4, and the hole measurement module 5 is turned on to measure the hole to be bored. The hole model before and after boring is established on the host computer. When boring is working, the drive motor 1 drives the boring tool 6 to move. The offset of the boring tool 6 is determined by the hole measurement module 5, and the offset is reduced by the six-bar linkage structure with linear motor 21, thereby controlling the entire boring machine in a relatively fixed position.

[0034] The boring machine spindle 4 has a bridge circuit inside, which is relatively independent from the spindle body itself and is wrapped with an insulating layer. This circuit allows the relative position of the boring tool 6 and the spindle 4 to be determined after the boring tool 6 is inserted into the spindle 4. The bridge circuit inside the boring machine spindle 4 is as follows: Figure 5 As shown, the formula for measuring the resistance at four points on the entire boring machine spindle is: ,in, for The sum of the resistance values ​​in series, The resistance value of the nth mounting hole 51 on spindle 4. The resistance values ​​are different. , and The resistors that make up the bridge circuit are... R4 is a protective resistor. Since the parallel resistance value at each mounting hole 51 is different, this distinguishes each mounting hole 51. Each parallel resistance has a fixed value, therefore, by adjusting... The position of the boring bar 6 can be determined by the resistance at that point.

[0035] The rotary encoder 24 is located at the hinge point between the guide rod 22 and the positioning module 2. The rotary encoder 24 is fixed on the positioning module 2. The rotation axis of the rotary encoder 24 rotates with the rotation axis between the guide rod 22 and the main body of the positioning module 2. A polar coordinate system is established by the grating displacement sensor and the rotary encoder 24 to determine the real-time position information between the fixing point of the magnetic bracket 25 and the first component 10 or the second component 11. The universal ring 7 is located on the boring machine positioning module 2 to ensure that the two ends of the spindle 4 in contact with the positioning module 2 can always reach the required positioning position when the portable boring machine positioning module 2 is in position.

[0036] The boring machine is controlled in a relatively fixed position by a six-bar linkage combined with a universal joint 7. The hole measurement module 5, which is mounted on the spindle 4, can accurately reflect the relative position between the boring machine and the hole being bored, thus improving the accuracy of boring positioning. Before starting boring, the operator can be provided with a comparison before and after boring via a host computer, allowing the operator to adjust the boring parameters directly and quickly. During use, the position of the boring tool 6 can be adjusted in real time by the positioning module 2 on the first component 10 and the second component 11 to reduce the error caused by the vibration of the components and the machine during boring. This avoids the problem that the machining accuracy of existing portable boring machines mainly relies on manual adjustment and lacks automatic control during operation, greatly improving boring efficiency and accuracy, and achieving good results.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
