Description

Technical Field

[0001] The invention belongs to the field of nut cutting and processing, in particular to side processing equipment for large nuts. Background Art

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

[0003] A patent document with publication number CN113941717A discloses a large nut end face cutting processing device, including a fixed base, a drive motor, a hydraulic three-jaw chuck and an automatic unloading mechanism. An automatic cutting mechanism is provided at the other end of the upper surface of the fixed base, and a rotating and moving mechanism is provided above the fixed base.

[0004] Traditional nut turning techniques typically use a chuck to clamp and rotate the nut, while a multi-axis CNC tool system simultaneously turns the nut's sides. However, when the number of sides of a nut needs to be precisely adjusted, such as when reworking a circular or polygonal nut into one with a specific, precise number of sides, the flexibility of traditional processes is significantly limited. In such cases, complex manual debugging and program modifications are required, limiting flexibility in machining the nut's side surfaces.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The side processing equipment for large nuts described in the present invention drives the nut to rotate one circle by rotating the end of the rotating connecting member. When the nut rotates, the detection wheel follows the rotation due to the action of friction. After the nut rotates one circle, the number of circles rotated by the wheel and the final angle are accurately detected by an externally arranged detection structure, and the circumference of the nut side is judged according to the circumference data of the detection wheel itself, so that the circumference of the nut turning position can be judged. The rotating connecting member drives the nut to rotate so that the angle of rotation of the detection wheel at this time corresponds to the required side length, and the nut can be marked again. This process is repeated. After the nut is marked, 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 cooperates with the multi-axis movement of the tool integrated frame to turn the marked position of the nut.

[0020] 2. The side processing equipment for large nuts described in the present invention is movably installed inside two fixed round blocks through the upper and lower shafts of the detection wheel, thereby ensuring the smooth rotation of the detection wheel. When the detection wheel 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 wheel will be detected by the angle sensor. When the detection wheel rotates one circle, the angle sensor will display that the rotation angle is cleared, so the angle sensor can detect the final rotation angle of the detection wheel.

[0021] 3. The side processing equipment for large nuts described in the present invention detects that when the rotating wheel contacts the outside of the nut, the initial position of the magnet column is closest to the counting sensor. When the rotating wheel rotates and drives the magnet column to rotate, each magnet column passes through one side of the counting sensor, and the counting sensor generates a pulse signal. By counting these pulse signals, the number of rotations of the rotating wheel is confirmed, and the circumference of the outside of the nut is detected. The data is accurately detected by separately detecting the angle and the number of rotations. The device can detect the circumference of any polygonal nut through the same technical means. Knowing the circumference of the nut can be used to detect the processing accuracy of the nut and optimize the feed path of the tool during turning. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] Example 1: Figure 1-4 As shown, the side processing equipment for large nuts according to the embodiment of the present invention includes a multi-axis mobile platform 1 and a tool integrated frame 11 fixedly installed above the multi-axis mobile platform 1, a driving mechanism 2 is fixedly installed on the side of the multi-axis mobile platform 1, a hydraulic multi-jaw chuck 3 is movably installed on one side of the driving mechanism 2, a guide column 12 is installed on one side of the hydraulic multi-jaw chuck 3, the guide column 12 is fixedly connected to the multi-axis mobile platform 1, a fixed outer ring 13 is fixedly installed on the outer side of the guide column 12, and a movable connecting member 2 6 and a movable connecting member 1 4 are fixedly installed on the side of the fixed outer ring 13 facing the hydraulic multi-jaw chuck 3, one end of the movable connecting member 2 6 is fixedly installed with a rotating connecting member 7, and one end of the movable connecting member 1 4 is fixedly installed with a detection component 5;

[0037] The detection component 5 includes a spiral lifting member 51 fixedly mounted on one end of a movable connecting member 4, a spiral column 52 is movably mounted on one side of the spiral lifting member 51, a spring guide column 53 is mounted on one end of the spiral column 52, a cylindrical block 54 is mounted on one end of the spring guide column 53, the spiral column 52 is connected to the cylindrical block 54 through the spring guide column 53, a detection wheel 55 is rotatably mounted inside the cylindrical block 54, and a component for detecting the number of rotations and the rotation angle of the detection wheel 55 is provided on the outside of the detection wheel 55.

[0038] Specifically, when it is necessary to turn the side of a large nut, especially to turn the original outer ring nut into the required polygonal nut, the nut to be processed is placed on the side of the hydraulic multi-jaw chuck 3, and the annular nut is fixed by multiple clamping jaws provided by the hydraulic multi-jaw chuck 3 itself. At this time, the nut is in a horizontal state, and the angle adjustment of the movable connecting member 2 6 and the function of driving the displacement of the rotating connecting member 7 are used to make the end of the rotating connecting member 7 in the middle of the nut and the two are tightly connected. The specific means can be to provide a telescopic and extrusion structure on the outer side of the end of the rotating connecting member 7 so that the end of the rotating connecting member 7 and the nut are tightly connected. At this time, the spiral lifting member 51 is adjusted by the adjustment of the movable connecting member 1 4. Align the outside of the nut, and drive the spiral lifting component 51 to make the spiral column 52 move inside the spiral lifting component 51, thereby controlling the horizontal displacement of the detection wheel 55, so that it rests on the outside of the nut, and slightly moving the clamping claws of the hydraulic multi-jaw chuck 3. At this time, the nut is suspended in the air, and its outside is in contact with the detection wheel 55. The end of the rotating connector 7 is rotated to drive the nut to rotate one circle. When the nut rotates, the detection wheel 55 follows the rotation due to the friction force. In this process, the telescopic function of the spring guide column 53 can make the detection wheel 55 adapt to the slight diameter difference that may appear on the outside of the nut. After the nut rotates one circle, the number of circles rotated by the wheel 55 and the final angle are accurately detected by the external detection structure. The circumference of the nut side can be judged according to the circumference data of the detection wheel 55 itself, and the nut turning position can be judged. The specific judgment method is to multiply the circumference of the detection wheel 55 by the number of turns of the detection wheel 55, and multiply the circumference of the detection wheel 55 by the angle percentage of the detection wheel 55. The angle percentage of the detection wheel 55 is that the final angle value of the detection wheel 55 is divided by 360 degrees. The sum of the two data is the circumference of the detected nut. The length of each side of the nut can be easily confirmed according to the circumference. If a quadrilateral nut is required, that is, the circumference of the nut side is divided by the four sides, based on the above, no matter how many sides it is, the required length of each side can be known. When the nut needs to be processed after detection, the angle data and the number of turns data are first cleared to zero, and the angle data and the detection data are compared at this time. The outer side of the nut contacted by the measuring wheel 55 is marked, and the nut is driven to rotate by the rotating connecting piece 7 so that the angle of rotation of the measuring wheel 55 at this time corresponds to the required side length, and the nut can be marked again, and this process is repeated. After the nut is marked, it can be clamped again by the hydraulic multi-jaw chuck 3, and then the driving mechanism 2 drives the hydraulic multi-jaw chuck 3 and the nut to rotate, and cooperates with the multi-axis movement of the tool integrated frame 11 to turn the marked position of the nut. The above-mentioned more complicated numerical conversion is calculated by the program. The technical solution of this device is to easily detect the circumference of the nut to be processed. Nuts with a specific number of sides required in specific circumstances can be processed by this device, which has strong flexibility. When the hydraulic multi-jaw chuck 3 rotates,By configuring movable connector 2 6 and movable connector 1 4, the rotating connector 7 and detection assembly 5 are rotated outside the hydraulic multi-jaw chuck 3 and at a 90-degree angle to the corresponding movable connector 2 6 and movable connector 1 4. When turning polygonal nuts, the tool needs to be moved along a predetermined trajectory to form the polygonal shape. By calculating the perimeter, the tool feed path can be planned more accurately, reducing machining errors and improving machining efficiency.

[0039] like Figure 5 As shown, the dotted line is the direction of turning processing, and the intersection of the dotted lines is the marked position. Through the implementation of this device, the outer ring type nut can be processed into a nut with the required number of sides.

[0040] like Figure 6 As shown, the movable connecting member 4 includes a fixed block 41 fixedly mounted on the side of the fixed outer ring 13, a telescopic rod 42 is fixedly mounted inside the fixed block 41, a fixed block 2 43 is fixedly mounted on one end of the telescopic rod 42, a support arm 46 is mounted on the side of the fixed block 2 43, a rotating connecting member 45 is movably mounted between the support arm 46 and the end of the fixed block 2 43, and the detection component 5 is mounted on one end of the support arm 46.

[0041] The movable connecting member 2 6 and the movable connecting member 1 4 are components made of the same structure. The movable connecting member 2 6 is used to adjust the position of the rotating connecting member 7, and the movable connecting member 1 4 is used to adjust the position of the detection component 5. A digital display screen 8 is fixedly installed on the outer side of the support arm 46, and the digital display screen 8 is used to display the data detected by the detection wheel 55.

[0042] A back plate 44 is also fixedly installed on the side of the fixed block 2 43. The thickness of the support arm 46 is smaller than the thickness of the fixed block 2 43. The minimum diameter between the back plate 44 and the outside of the hydraulic multi-jaw chuck 3 is larger than the minimum diameter between the support arm 46 and the outside of the hydraulic multi-jaw chuck 3.

[0043] Specifically, when the detection wheel 55 needs to contact the side of the nut, the support arm 46 rotates on one side of the fixed block 2 43 through the rotating connection 45. Under the obstruction of the abutment plate 44, the support arm 46 and the fixed block 2 43 are changed from the original 90-degree state to a vertical state. At this time, the detection wheel 55 and the nut are on the same side of the hydraulic multi-jaw chuck 3. Through the setting of the spiral lifting component 1 51, the spiral column 52 and the detection wheel 55 are moved toward the side of the nut until the outer side of the detection wheel 55 contacts the side of the nut, thereby adapting to nuts of different diameters. The digital display screen 8 can display the number of revolutions of the detection wheel 55 and the final angle, as well as the circumference data converted based on these two data.

[0044] like Figure 7-8As shown, a rectangular component groove 541 is opened inside the cylindrical block 54 , two fixed round blocks 542 are fixedly installed on the side of the cylindrical block 54 , and the detection wheel 55 is movably installed between the two fixed round blocks 542 .

[0045] An angle sensor 56 is fixedly installed above the corresponding fixed round block 542 . The angle sensor 56 is connected to the end shaft of the detection wheel 55 via an axis passing through the fixed round block 542 . The angle sensor 56 is used to detect the rotation angle of the detection wheel 55 .

[0046] Specifically, the upper and lower axes of the detection wheel 55 are movably installed inside the two fixed round blocks 542, thereby ensuring the smooth rotation of the detection wheel 55. When the detection wheel 55 rotates, the axis connected to the angle sensor 56 also rotates, and the rotation angle of the axis can be detected by the angle sensor 56, that is, the rotation angle of the detection wheel 55 will be detected by the angle sensor 56. When the detection wheel 55 rotates one circle, the angle sensor 56 will display that the rotation angle is cleared, so the angle sensor 56 can detect the final rotation angle of the detection wheel 55.

[0047] like Figure 10 As shown, the rotary connector 7 includes a second spiral lifting component 71 and a rotary column 72 movably mounted on the lower end of the second spiral lifting component 71 , and a radial telescopic extrusion mechanism 73 is movably mounted on the outer side of the rotary column 72 .

[0048] Specifically, the radial telescopic extrusion mechanism 73 produces an effect of pushing the multiple arc blocks or other shaped blocks at the end of the rotating column 72 away from the rotating column 72 at the same time through the telescopic structure, until the multiple arc blocks or other shaped blocks are squeezed with the inner wall of the nut, and the telescopic rod 42 provided on the movable connecting member 6 is telescoped so that the axis of the rotating column 72 and the axis of the nut are on the same vertical line, and then the rotating column 72 and the radial telescopic extrusion mechanism 73 are driven by the spiral lifting component 71 to descend until the radial telescopic extrusion mechanism 73 is inside the nut.

[0049] Example 2: Figure 9 and Figure 11 As shown, compared with Example 1, another embodiment of the present invention is: a counting sensor 543 is also fixedly installed inside the rectangular component groove 541, and one end of the counting sensor 543 is set toward the detection wheel 55, and the counting sensor 543 is used to detect the number of rotations of the detection wheel 55.

[0050] The outer side of the detection wheel 55 is smoothly designed, and a middle ring groove 551 is opened in the middle of the detection wheel 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 smaller than the minimum distance between the detection wheel 55 and the counting sensor 543.

[0051] The counting sensor 543 is used to detect the number of revolutions of the magnet column 552 following the detection wheel 55 and count the revolutions. The counting sensor 543 detects the change in magnetic field strength and outputs a corresponding voltage pulse. When the magnet column 552 is closest to one side of the sensor, the counting sensor 543 generates a pulse signal.

[0052] Specifically, when the detection wheel 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 wheel 55 rotates to drive the magnet column 552 to rotate, each magnet column 552 passes through one side of the counting sensor 543, and the counting sensor 543 generates a pulse signal. By counting these pulse signals, the number of rotations of the detection wheel 55 is confirmed, and the circumference of the outside of the nut is detected. The data is accurately detected by separately detecting the angle and the number of turns. When the original polygonal nut needs to be turned into another polygonal nut, the original polygonal nut is usually turned into an outer ring nut first, and then implemented through this device to convert it into another polygonal nut with the required number of sides. The device can detect the circumference of any polygonal nut through the same technical means. Knowing the circumference of the nut can be used to detect the processing accuracy of the nut and optimize the feed path of the tool during turning.

[0053] Working principle: When it is necessary to turn the side of a large nut, especially to turn the original outer ring nut into the required polygonal nut, place the nut to be processed on the side of the hydraulic multi-jaw chuck 3, and fix the annular nut by multiple clamping 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 2 6 and the function of driving the displacement of the rotating connecting member 7, the end of the rotating connecting member 7 is placed in the middle of the nut and the two are tightly connected. The specific means can be to set a telescopic and extrusion structure on the outside of the end of the rotating connecting member 7 so that the end of the rotating connecting member 7 and the nut are tightly connected. At this time, through the adjustment of the movable connecting member 1 4, the spiral lifting member 1 5 1 is aligned with the outside of the nut, and the spiral column 52 is driven by the spiral lifting component 51 to move inside the spiral lifting component 51, thereby controlling the horizontal displacement of the detection wheel 55, making it rest against the outside of the nut, and slightly moving the clamping claws of the hydraulic multi-jaw chuck 3. At this time, the nut is suspended in the air, and its outer side is in contact with the detection wheel 55. The end of the rotating connector 7 is rotated to drive the nut to rotate one circle. When the nut rotates, the detection wheel 55 follows the rotation due to the friction force. In this process, the telescopic function of the spring guide column 53 can make the detection wheel 55 adapt to the slight diameter difference that may appear on the outside of the nut. After the nut rotates one circle, the number of circles rotated by the wheel 55 and the final angle are accurately detected by the external detection structure. The circumference of the nut side can be judged according to the circumference data of the detection wheel 55 itself, and the nut turning position can be judged. The specific judgment method is to multiply the circumference of the detection wheel 55 by the number of turns of the detection wheel 55, and multiply the circumference of the detection wheel 55 by the angle percentage of the detection wheel 55. The angle percentage of the detection wheel 55 is that the final angle value of the detection wheel 55 is divided by 360 degrees. The sum of the two data is the circumference of the detected nut. The length of each side of the nut can be easily confirmed according to the circumference. If a quadrilateral nut is required, that is, the circumference of the nut side is divided by the four sides, based on the above, no matter how many sides it is, the required length of each side can be known. When the nut needs to be processed after detection, the angle data and the number of turns data are first cleared to zero, and the angle data and the detection data are compared at this time. The outer side of the nut contacted by the measuring wheel 55 is marked, and the nut is driven to rotate by the rotating connecting piece 7 so that the angle of rotation of the measuring wheel 55 at this time corresponds to the required side length, and the nut can be marked again, and this process is repeated. After the nut is marked, it can be clamped again by the hydraulic multi-jaw chuck 3, and then the driving mechanism 2 drives the hydraulic multi-jaw chuck 3 and the nut to rotate, and cooperates with the multi-axis movement of the tool integrated frame 11 to turn the marked position of the nut. The above-mentioned more complicated numerical conversion is calculated by the program. The technical solution of this device is to easily detect the circumference of the nut to be processed. Nuts with a specific number of sides required in specific circumstances can be processed by this device, which has strong flexibility. When the hydraulic multi-jaw chuck 3 rotates,By setting the movable connecting member 2 6 and the movable connecting member 1 4, the rotating connecting member 7 and the detection component 5 are rotated to the outside of the hydraulic multi-jaw chuck 3 and are 90 degrees with the corresponding movable connecting member 2 6 and the movable connecting member 1 4. When turning a polygonal nut, it is necessary to move the tool along a predetermined trajectory to form a polygonal shape. By calculating the perimeter, the feed path of the tool can be planned more accurately, the processing error can be reduced, and the processing efficiency can be improved. When the detection wheel 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 wheel 55 rotates and drives the magnet column 552 to rotate, each magnet column 552 passes the counting sensor 543. On one side, the counting sensor 543 generates a pulse signal. By counting these pulse signals, the number of rotations of the detection wheel 55 is confirmed, and the circumference of the outer side of the nut is detected. By separately detecting the angle and the number of rotations, the data is accurately detected. When the original polygonal nut needs to be turned into another polygonal nut, the original polygonal nut is usually first turned into an outer ring nut. Then, this device is used to convert it into another polygonal nut with the required number of sides. The device can detect the circumference of any polygonal nut using the same technical means. Knowing the circumference of the nut can be used to detect the processing accuracy of the nut and optimize the feed path of the tool during turning.
