Description

Technical Field

[0001] The present invention belongs to the field of nut cutting and machining, specifically a side machining device for large nuts. Background Art

[0002] Nut turning is a key machining process in the field of mechanical manufacturing, especially important in the production of large nuts. The side structure of large nuts usually includes complex features such as an outer cylindrical surface, a polygonal surface, and an irregular surface. During the machining process, first, the nut is firmly clamped by a three-jaw or four-jaw chuck and driven to rotate at high speed. Subsequently, through a numerically controlled tool rest with multi-axis linkage function, various turning tools are brought into contact with the side of the high-speed rotating nut according to a preset trajectory to achieve precise turning of the nut side, thereby completing the forming machining of features such as the outer circle, polygon, and irregular surface.

[0003] A patent document with the publication number CN113941717A discloses a large nut end face cutting and machining device, including a fixed base, a driving motor, a hydraulic three-jaw chuck, and an automatic blanking mechanism. At the other end of the upper surface of the fixed base, there is an automatic cutting mechanism, and a rotating and moving mechanism is arranged above the fixed base.

[0004] In traditional nut turning technology, usually a chuck is used to clamp and drive the nut to rotate, and at the same time, a numerically controlled tool system with multi-axis linkage is used to turn the side of the nut. However, when it is necessary to precisely adjust the number of sides of the nut, for example, re-machining an original annular or polygonal nut into a nut with a specific precise number of sides, the flexibility of the traditional process is greatly limited. In this case, complex debugging and program modification need to be carried out manually, and the flexibility of nut side machining is relatively low.

[0005] Therefore, the present invention provides a side machining device for large nuts. Summary of the Invention

[0010] Preferably, a resisting plate is also fixedly installed on the side of the fixed block II. The thickness of the support arm is smaller than the thickness of the fixed block II. The minimum diameter between the resisting plate and the outer side of the hydraulic multi-jaw chuck is greater than the minimum diameter between the support arm and the outer side of the hydraulic multi-jaw chuck.

[0011] Preferably, a rectangular component groove is opened inside the cylindrical block. Two fixed circular blocks are fixedly installed on the side of the cylindrical block. The detection rotating wheel is movably installed between the two fixed circular blocks.

[0012] Preferably, an angle sensor is fixedly installed above the corresponding fixed circular block. The angle sensor is connected to the end shaft of the detection rotating wheel through a shaft passing through the fixed circular block.

[0016] Preferably, the rotary connecting member includes a second spiral lifting member and a rotating column movably installed at the lowermost end of the second spiral lifting member. A radial telescopic extrusion mechanism is movably installed on the outer side of the rotating column.

[0017] The beneficial effects of the present invention are as follows: 1. For the side processing equipment for large nuts of the present invention, by rotating the end of the rotary connecting member to drive the nut to rotate one circle. When the nut rotates, due to the action of friction, the detection runner rotates accordingly. After the nut rotates one circle, an externally set detection structure is used to accurately detect the number of rotations and the final angle of the detection runner, and then based on the perimeter data of the detection runner itself, the perimeter of the side of the nut can be judged, so as to judge the turning position of the nut. The rotary connecting member drives the nut to rotate, so that the angle of rotation of the detection runner at this time corresponds to the required side length, and then the nut can be marked again. Repeating this process, after marking the nut, it can be clamped again by the hydraulic multi-jaw chuck, and then the driving mechanism drives the hydraulic multi-jaw chuck and the nut to rotate, and in cooperation with the multi-axis movement of the tool integrated rack, the marked position of the nut is turned and processed.

[0018] 2. For the side processing equipment for large nuts of the present invention, the detection runner is movably installed on the upper and lower two shafts inside two fixed circular blocks, thereby ensuring the smooth rotation of the detection runner. When the detection runner rotates, the shaft connected to the angle sensor also rotates, and the rotation angle of the shaft can be detected by the angle sensor, that is, the rotation angle of the detection runner will be detected by the angle sensor. When the detection runner rotates one circle, the angle sensor will display that the rotation angle is cleared to zero.

[0019] 3. For the side processing equipment for large nuts according to the present invention, when the detection runner contacts the outer side of the nut, the initial position of the magnet column is closest to the counting sensor. When the detection runner rotates to drive the magnet column to rotate, each time the magnet column passes by one side of the counting sensor, the counting sensor generates a pulse signal. By counting these pulse signals, the number of rotations of the detection runner can be confirmed, and then the perimeter of the outer side of the nut can be detected. By separately detecting the angle and the number of rotations, the data can be accurately detected. This device can detect the perimeter of any polygonal nut by the same technical means. By knowing the perimeter of the nut, the processing accuracy of the nut and the feed path of the cutting tool during turning processing can be optimized. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0024] Example 1: As Figures 1-4 shown, the side processing equipment for large nuts in the embodiment of the present invention includes a multi-axis moving platform 1 and a tool integrated rack 11 fixedly installed above the multi-axis moving platform 1. A driving mechanism 2 is fixedly installed on the side of the multi-axis moving platform 1. A hydraulic multi-jaw chuck 3 is movably installed on one side of the driving mechanism 2. A guide post 12 is installed on one side of the hydraulic multi-jaw chuck 3. The guide post 12 is fixedly connected to the multi-axis moving platform 1. A fixed outer ring 13 is fixedly installed on the outer side of the guide post 12. A second movable connector 6 and a first movable connector 4 are fixedly installed on the side of the fixed outer ring 13 facing the hydraulic multi-jaw chuck 3. A rotating connector 7 is fixedly installed at one end of the second movable connector 6. A detection assembly 5 is fixedly installed at one end of the first movable connector 4; The detection assembly 5 includes a first screw-lifting member 51 fixedly installed at one end of the first movable connector 4. A screw column 52 is movably installed on one side of the first screw-lifting member 51. A spring guide post 53 is installed at one end of the screw column 52. A cylindrical block 54 is installed at one end of the spring guide post 53. The screw column 52 is connected to the cylindrical block 54 through the spring guide post 53. A detection runner 55 is rotatably installed inside the cylindrical block 54. A component for detecting the number of rotation turns and rotation angle of the detection runner 55 is arranged on the outer side of the detection runner 55.

[0025] Specifically, when turning the side of a large nut, especially when turning a nut with an original outer ring into a required polygonal nut, place the nut to be processed on the side of the hydraulic multi-jaw chuck 3. Fix the ring-shaped nut with multiple jaws provided by the hydraulic multi-jaw chuck 3 itself. At this time, the nut is in a horizontal state. Through the angle adjustment of the second movable connector 6 and the function of driving the displacement of the rotating connector 7, the end of the rotating connector 7 is located at the middle part of the nut and the two are tightly connected. The specific method can be to set a telescopic and squeezing structure outside the end of the rotating connector 7 to tightly connect the end of the rotating connector 7 and the nut. At this time, through the adjustment of the first movable connector 4, the first screw-lifting member 51 is aligned with the outside of the nut. Through the drive of the first screw-lifting member 51, the screw column 52 moves inside the first screw-lifting member 51, thereby controlling the horizontal displacement of the detection runner 55 so that it abuts against the outside of the nut. Slightly move the jaws of the hydraulic multi-jaw chuck 3. At this time, the nut is suspended in the air and its outside contacts the detection runner 55. Rotate the end of the rotating connector 7 to drive the nut to rotate one circle. When the nut rotates, due to the action of friction, the detection runner 55 rotates accordingly. During this process, the telescopic function of the spring guide post 53 can enable the detection runner 55 to adapt to the slight diameter difference that may occur on the outside of the nut. After the nut rotates one circle, use an externally set detection structure to accurately detect the number of turns and the final angle of the rotation of the detection runner 55, and then judge the circumference of the nut side according to the circumference data of the detection runner 55 itself. The specific judgment method is to multiply the circumference of the detection runner 55 by the number of turns of the rotation of the detection runner 55, and multiply the angle percentage of the detection runner 55 by the circumference of the detection runner 55. The angle percentage of the detection runner 55 is the final angle value of the detection runner 55 divided by 360 degrees. The sum of the two data is the circumference of the detected nut. According to the circumference, it is easy to confirm the length of each side of the nut. If a quadrilateral nut is required, that is, the circumference of the nut side is divided by four sides. To sum up, no matter how many sides it is, the required length of each side can be known. When processing the nut after detection, first clear the angle data and the number-of-turns data, mark the outside of the nut that is in contact with the detection runner 55 at this time. Drive the nut to rotate through the rotating connector 7 so that the angle of rotation of the detection runner 55 at this time corresponds to the required side length, and then mark the nut again. Repeat this process. After marking the nut, it can be clamped again by the hydraulic multi-jaw chuck 3, and then the drive mechanism 2 is driven to drive the hydraulic multi-jaw chuck 3 and the nut to rotate, and cooperate with the multi-axis movement of the tool integrated rack 11 to turn the marked position of the nut. The above relatively complex numerical conversion is calculated by a program. The technical solution of this device is to easily detect the circumference of the nut to be processed. Nuts with specific numbers of sides required in specific situations can all be processed by this device, with strong flexibility. When the hydraulic multi-jaw chuck 3 rotates,Through the settings of the second movable connector 6 and the first movable connector 4, the rotating connector 7 and the detection component 5 are rotated to the outside of the hydraulic multi-jaw chuck 3 and are at a 90-degree angle to the corresponding second movable connector 6 and the first movable connector 4. When turning a polygonal nut, the tool needs to be moved along a predetermined trajectory to form a polygonal shape. By calculating the perimeter, the feed path of the tool can be planned more accurately, reducing machining errors and improving machining efficiency.

[0026] As Figure 5 shown, the dotted line is the direction of turning, and the intersection of the dotted lines is the marking position. Through the implementation of this device, the outer ring-shaped nut can be processed into a nut with the required number of sides.

[0027] As Figure 6 shown, the first movable connector 4 includes a first fixed block 41 fixedly installed on the side of the fixed outer ring 13. A telescopic rod 42 is fixedly installed inside the first fixed block 41. One end of the telescopic rod 42 is fixedly installed with a second fixed block 43. A support arm 46 is installed on the side of the second fixed block 43. A rotating connector 45 is movably installed between the end of the support arm 46 and the second fixed block 43. The detection component 5 is installed at one end of the support arm 46.

[0028] The second movable connector 6 and the first movable connector 4 are components made of the same structure. The second movable connector 6 is used to adjust the position of the rotating connector 7, and the first movable connector 4 is used to adjust the position of the detection component 5. A digital display screen 8 is fixedly installed on the outside of the support arm 46. The digital display screen 8 is used to display the data detected by the detection runner 55.

[0029] A retaining plate 44 is also fixedly installed on the side of the second fixed block 43. The thickness of the support arm 46 is less than the thickness of the second fixed block 43. The minimum diameter between the retaining plate 44 and the outside of the hydraulic multi-jaw chuck 3 is greater than the minimum diameter between the support arm 46 and the outside of the hydraulic multi-jaw chuck 3.

[0030] Specifically, when it is necessary to make the detection runner 55 contact the side of the nut, the support arm 46 rotates on one side of the second fixed block 43 through the rotating connector 45. Under the obstruction of the retaining plate 44, the support arm 46 and the second fixed block 43 are changed from the original 90-degree state to a vertical state. At this time, both the detection runner 55 and the nut are on the same side of the hydraulic multi-jaw chuck 3. Through the setting of the first screw-lifting component 51, the screw column 52 and the detection runner 55 move towards the side of the nut until the outside of the detection runner 55 contacts the side of the nut, thereby adapting to nuts of different diameters. The digital display screen 8 can display the number of turns and the final angle of rotation of the detection runner 55, as well as the perimeter data calculated from these two data.

[0031] As Figures 7-8As shown, a rectangular component groove 541 is provided inside the cylindrical block 54. Two fixed circular blocks 542 are fixedly installed on the side of the cylindrical block 54. The detection runner 55 is movably installed between the two fixed circular blocks 542.

[0032] Above the corresponding fixed circular block 542, an angle sensor 56 is fixedly installed. The angle sensor 56 is connected to the end shaft of the detection runner 55 through a shaft passing through the fixed circular block 542. The angle sensor 56 is used to detect the rotation angle of the detection runner 55.

[0033] Specifically, the upper and lower shafts of the detection runner 55 are movably installed inside the two fixed circular blocks 542, thereby ensuring the smooth rotation of the detection runner 55. When the detection runner 55 rotates, the shaft connected to the angle sensor 56 also rotates. The rotation angle of the shaft can be detected by the angle sensor 56, that is, the rotation angle of the detection runner 55 will be detected by the angle sensor 56. When the detection runner 55 rotates one circle, the angle sensor 56 will display that the rotation angle is cleared to zero. Therefore, the angle sensor 56 can detect the final rotation angle of the detection runner 55.

[0034] As Figure 10 shown, the rotary connector 7 includes a spiral lifting member two 71 and a rotary column 72 movably installed at the lowermost end of the spiral lifting member two 71. A radial telescopic extrusion mechanism 73 is movably installed on the outer side of the rotary column 72.

[0035] Specifically, the effect produced by the radial telescopic extrusion mechanism 73 is to push multiple arc-shaped blocks or blocks of other shapes at the end of the rotary column 72 away from the rotary column 72 simultaneously through the telescopic structure until the multiple arc-shaped blocks or blocks of other shapes form an extrusion with the inner wall of the nut. By expanding and contracting the telescopic rod 42 provided on the movable connector two 6, the axis of the rotary column 72 and the axis of the nut are on the same vertical line. Subsequently, under the drive of the spiral lifting member two 71, the rotary column 72 and the radial telescopic extrusion mechanism 73 are lowered until the radial telescopic extrusion mechanism 73 is inside the nut.

[0036] Embodiment 2: As Figure 9 and Figure 11 shown, compared with Embodiment 1, another implementation manner of the present invention is: a counting sensor 543 is also fixedly installed inside the rectangular component groove 541. One end of the counting sensor 543 faces the detection runner 55. The counting sensor 543 is used to detect the number of rotations of the detection runner 55.

[0037] The outer side of the detection runner 55 is smoothly provided. A middle ring groove 551 is provided in the middle part of the detection runner 55. A magnet column 552 is fixedly installed inside the middle ring groove 551. The minimum distance between the magnet column 552 and the counting sensor 543 is less than the minimum distance between the detection runner 55 and the counting sensor 543.

[0038] The counting sensor 543 is used to detect the number of turns of the magnet column 552 following the rotation of the detection runner 55 for counting. The counting sensor 543 detects the change in magnetic field intensity and outputs corresponding voltage pulses. When the side of the magnet column 552 closest to the sensor, the counting sensor 543 generates a pulse signal.

[0039] Specifically, when the detection runner 55 contacts the outside of the nut, the initial position of the magnet column 552 is closest to the counting sensor 543. When the detection runner 55 rotates to drive the magnet column 552 to rotate, each time the magnet column 552 passes by one side of the counting sensor 543, the counting sensor 543 generates a pulse signal. By counting these pulse signals, the number of turns of the detection runner 55 is confirmed, and then the perimeter of the outside of the nut is detected. The data is accurately detected by separately detecting the angle and the number of turns. When a polygon nut needs to be turned into another polygon nut, usually the original polygon nut is first turned into an outer ring nut, and then implemented through this device to transform it into another polygon nut with the required number of sides. And this device can detect the perimeter of any polygon nut by the same technical means. Knowing the perimeter of the nut can be used to detect the machining accuracy of the nut and optimize the feed path of the tool during turning.

[0040] Working principle: When turning the side of a large nut, especially when turning an originally outer-ring nut into a required polygonal nut, place the nut to be processed on the side of the hydraulic multi-jaw chuck 3. Fix the ring-shaped nut through multiple jaws provided by the hydraulic multi-jaw chuck 3 itself. At this time, the nut is in a horizontal state. Through the angle adjustment of the movable connecting member II 6 and the function of driving the displacement of the rotating connecting member 7, the end of the rotating connecting member 7 is located at the middle part of the nut and the two are tightly connected. Specifically, a telescopic and squeezing structure can be set outside the end of the rotating connecting member 7 to tightly connect the end of the rotating connecting member 7 and the nut. At this time, through the adjustment of the movable connecting member I 4, the screw lifting member I 51 is aligned with the outside of the nut. Through the drive of the screw lifting member I 51, the screw column 52 moves inside the screw lifting member I 51, thereby controlling the horizontal displacement of the detection runner 55 to make it abut against the outside of the nut. Slightly move the jaws of the hydraulic multi-jaw chuck 3. At this time, the nut is suspended in the air and its outside contacts the detection runner 55. Rotate the end of the rotating connecting member 7 to drive the nut to rotate one circle. When the nut rotates, due to the action of friction, the detection runner 55 rotates accordingly. During this process, the telescopic function of the spring guide post 53 can enable the detection runner 55 to adapt to the slight diameter difference that may occur on the outside of the nut. After the nut rotates one circle, use the externally set detection structure to accurately detect the number of turns and the final angle of the rotation of the detection runner 55, and then judge the perimeter of the nut side according to the perimeter data of the detection runner 55 itself. The specific judgment method is to multiply the perimeter of the detection runner 55 by the number of turns of the rotation of the detection runner 55, and multiply the angle percentage of the detection runner 55 by the perimeter of the detection runner 55. The angle percentage of the detection runner 55 is the final angle value of the detection runner 55 divided by 360 degrees. The sum of the two data is the perimeter of the detected nut. According to the perimeter, it is easy to confirm the length of each side of the nut. If a quadrilateral nut is required, that is, the perimeter of the nut side is divided by four sides. To sum up, no matter how many sides it is, the required length of each side can be known. When processing the nut after detection, first clear the angle data and the number of turns data, mark the outside of the nut that is in contact with the detection runner 55 at this time. Drive the nut to rotate through the rotating connecting member 7 so that the angle of rotation of the detection runner 55 at this time corresponds to the required side length, and then mark the nut again. Repeat this process. After marking the nut, it can be clamped again by the hydraulic multi-jaw chuck 3, and then the drive mechanism 2 is driven to drive the hydraulic multi-jaw chuck 3 and the nut to rotate, and cooperate with the multi-axis movement of the tool integrated rack 11 to turn the marked position of the nut. The above relatively complex numerical conversion is calculated through a program. The technical solution of this device is to easily detect the perimeter of the nut to be processed. Nuts with specific numbers of sides required in specific situations can all be processed by this device, with strong flexibility. When the hydraulic multi-jaw chuck 3 rotates,Through the settings of the second movable connector 6 and the first movable connector 4, the rotating connector 7 and the detection assembly 5 rotate outside the hydraulic multi-jaw chuck 3 and are at a 90-degree angle with the corresponding second movable connector 6 and the first movable connector 4. When turning a polygonal nut, the tool needs to move along a predetermined trajectory to form a polygonal shape. By calculating the perimeter, the feed path of the tool can be planned more accurately, reducing machining errors and improving machining efficiency. When the detection runner 55 contacts the outer side of the nut, the initial position of the magnet column 552 is closest to the counting sensor 543. When the detection runner 55 rotates to drive the magnet column 552 to rotate, each time the magnet column 552 passes by one side of the counting sensor 543, the counting sensor 543 generates a pulse signal. By counting these pulse signals, the number of rotations of the detection runner 55 can be confirmed, and then the perimeter of the outer side of the nut can be detected. The data is accurately detected by the method of separately detecting the angle and the number of rotations. When it is necessary to turn the original polygonal nut into another polygonal nut, usually the original polygonal nut is first turned into an outer ring nut, and then implemented by this device to transform it into another polygonal nut with the required number of sides. And this device can detect the perimeter of any polygonal nut by the same technical means. Knowing the perimeter of the nut can be used to detect the machining accuracy of the nut and optimize the feed path of the tool during turning.
