Description
Technical Field
[0001] This invention relates to the field of machining ring-shaped components, and particularly to an intelligent cutting device for machining ring-shaped components equipped with an adaptive algorithm. Background Technology
[0002] Machining of casing-type ring components is a crucial step in the manufacturing of high-end equipment such as aero-engines. These parts are mostly thin-walled, irregularly shaped, hollow rotating bodies with complex structures and extremely high dimensional accuracy requirements. The machining process typically begins with blank preparation, followed by turning, milling, drilling, and other processes to remove excess material and gradually form the basic outline.
[0003] Before machining ring-shaped components, they must be precisely secured. Generally, a suitable fixture is selected based on the ring's size and shape, and then mounted on the machining equipment's worktable. The ring is then placed stably within the fixture, and its positioning elements are used to clamp it from the outer circumference or a specific location. By adjusting the clamping force, the ring is ensured to be stable and evenly stressed, preventing displacement or vibration during machining.
[0004] The above-mentioned fixing process has shortcomings, and manual adjustment of clamping force is difficult to control precisely, easily resulting in excessive clamping force that damages the ring or insufficient clamping force that leads to unstable processing. Furthermore, due to the diverse specifications of casing-type rings, traditional fixing methods are inflexible and increase preparation time and costs. Summary of the Invention
[0005] This invention provides an intelligent cutting device for machining casing-type ring parts equipped with an adaptive algorithm, which can solve the problems in the prior art that the traditional fixing method is difficult to handle flexibly due to the diverse specifications of casing-type ring parts, thus increasing preparation time and cost.
[0006] An intelligent cutting device for machining casing-type ring parts equipped with an adaptive algorithm includes a base and a cutting assembly located above the base. A rotating platform is mounted on the base, and an adaptive clamping mechanism is mounted on the rotating platform. A lifting mechanism is mounted on the side of the base, and a placement plate is mounted at the output end of the lifting mechanism. The placement plate is located directly above the adaptive clamping mechanism, and a transmission assembly is provided between the placement plate and the rotating platform. The placement plate has a clamping opening for cooperating with the clamping parts of the adaptive clamping mechanism. A support frame is mounted on one side of the base, and a rangefinder for detecting the relative distance of the casing-type ring parts is mounted on the support frame. The device is also equipped with an adaptive system. The rotating platform drives the casing-type ring parts to rotate, and the rangefinder collects the relative distance information between the ring parts and the target. The radius is then calculated based on the rotation period and distance information. Finally, the adaptive clamping mechanism confirms the clamping radius based on the detected radius.
[0007] As a further aspect of the present invention: the adaptive clamping mechanism includes four sets of clamping components, which are evenly distributed around each other and are linked together. Each set of clamping components has a corresponding clamping opening on its upper part.
[0008] As a further aspect of the present invention: each set of clamping components includes an outer fixing block fixedly disposed radially outside the rotating platform and an inner fixing block fixedly disposed radially inside the rotating platform. A threaded rod is rotatably disposed between the outer fixing block and the inner fixing block. A fixing clamp is threaded onto the threaded rod, and an L-shaped fixing plate is disposed at the upper end of the fixing clamp. Each set of threaded rods passes through the inner fixing block at one end near the center of the rotating platform. At least two sets of threaded rods are coaxially fixedly connected. A set of bevel gears is coaxially fixed on the two sets of threaded rods. The other two sets of threaded rods have opposite thread directions, and bevel gears are fixedly disposed at their adjacent ends. Adjacent bevel gears mesh with each other.
[0009] As a further aspect of the present invention: each set of external fixing blocks is fixedly provided with a pressure guide plate between it and the corresponding internal fixing block. The pressure guide plate has an inverted V-shaped cross section and slides in cooperation with the fixing clamp.
[0010] As a further aspect of the present invention: a driving mechanism is provided on the support frame, the driving mechanism includes an automatic pushing device fixedly connected to the support frame, a motor assembly that slides with the support frame is fixedly provided at the output end of the automatic pushing device, a docking sleeve is fixedly provided at the output end of the motor assembly, at least one set of threaded rods passes through the outer fixing block, and a docking block that cooperates with the docking sleeve is coaxially fixedly provided.
[0011] As a further embodiment of the present invention: the transmission assembly includes a sleeve fixedly disposed on the upper surface of the rotating platform, and a sleeve that slides with the sleeve and is fixedly connected to the bottom of the placement plate.
[0012] As a further embodiment of the present invention: the lifting mechanism includes an automatic lifting device, the output end of which is fixedly provided with a positioning ring, the placement plate is rotatably fitted into the inner side of the positioning ring, and a bearing is provided between the placement plate and the positioning ring.
[0013] As a further aspect of the present invention: an electric baffle is provided on the support frame in front of the rangefinder.
[0014] As a further aspect of the present invention: a limiting block that cooperates with the clamping opening is fixedly disposed above the outer fixing block.
[0015] As a further aspect of the present invention, an airflow cleaning component is provided on one side of the base.
[0016] Compared with the prior art, this application has at least the following technical effects: The beneficial effects of this invention are: 1. In use, the automatic lifting device raises the placement plate, aligning the bottom of the casing-type ring with the output end of the rangefinder. The rotating platform drives the casing-type ring to rotate, and the rangefinder collects relative distance information to generate a time-distance curve, thereby calculating the radius. Then, the automatic pushing device pushes the motor assembly, causing the docking head to align with the docking block. The motor assembly drives a set of threaded rods to rotate, and multiple sets of threaded rods are linked through bevel gears, causing the fixing plate to move accordingly. The adaptive clamping mechanism moves the fixing plate at a suitable distance based on the detected radius, and the L-shaped fixing plate pushes the casing-type ring along the clamping opening, making it coaxial with the rotating platform and securing it to the bottom edge. The entire process requires no manual intervention, can quickly adapt to casing-type rings of different specifications, reduces preparation time and cost, and improves processing efficiency and flexibility.
[0017] 2. In use, when the fixed clamping plate is engaged with the bottom edge of the casing-like ring component, the automatic lifting device pushes the positioning ring slightly upward, causing the placement plate to move the casing-like ring component upward a certain distance. The fixed clamping plate remains engaged throughout. The compression of the casing-like ring component by the placement plate and the fixed clamping plate effectively prevents it from shaking or shifting during rotation, ensuring processing accuracy and quality, and meeting high-precision processing requirements. The sleeve and bushing in the transmission assembly cooperate to allow the placement plate to move vertically above the rotating platform. While pushing the casing-like ring component to the rangefinder detection area, the rotating platform drives the placement plate to rotate stably. The limiting block on the outer fixed block limits the placement plate through the clamping port, working together with the transmission assembly to drive the placement plate to rotate, further enhancing rotational stability.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0021] like Figures 1 to 4 As shown in the figure, an intelligent cutting device for machining casing-type ring parts equipped with an adaptive algorithm provided by an embodiment of the present invention includes a base 1 and a cutting assembly 10 located above the base 1. A rotating platform 2 is provided on the base 1, and an adaptive clamping mechanism 3 is installed on the rotating platform 2. A lifting mechanism 4 is provided on the side of the base 1, and a placement plate 5 is provided at the output end of the lifting mechanism 4. The placement plate 5 is located directly above the adaptive clamping mechanism 3. A transmission assembly 9 for synchronous rotation is provided between the placement plate 5 and the rotating platform 2, and a clamping port 501 for cooperating with the clamping component of the adaptive clamping mechanism 3 is provided on the placement plate 5. A support frame 6 is provided on one side of the base 1, and a rangefinder 8 for detecting the relative distance of the casing-type ring parts is provided on the support frame 6. The device is also equipped with an adaptive system. During operation, the lifting mechanism 4 drives the placement plate 5 to move upward, thereby driving the casing-type ring parts to move upward away from the adaptive clamping mechanism 3, so that the bottom of the casing-type ring parts is flush with the output end of the rangefinder 8. The rotating platform 2 drives the housing-like ring component to rotate, and the rangefinder 8 collects the relative distance information between itself and the housing-like ring component, generating a time-distance curve. The radius is then calculated using the rotation period and distance information (the calculation formula and reasoning process are appended later and will not be repeated here). Finally, the lifting mechanism 4 moves the placement plate 5 downwards, facilitating the adaptive clamping mechanism 3 to fix the housing-like ring component. The adaptive clamping mechanism 3 confirms the clamping radius based on the detected radius.
[0022] The adaptive clamping mechanism 3 includes four sets of clamping components, which are evenly distributed around each other and interconnected. Each set of clamping components has a corresponding clamping opening 501. Specifically, each set of clamping components includes an outer fixing block 301 fixedly disposed radially outside the rotating platform 2 and an inner fixing block 302 fixedly disposed radially inside the rotating platform 2. A threaded rod 304 is rotatably disposed between the outer fixing block 301 and the inner fixing block 302. A fixing plate 306 is threaded onto the threaded rod 304, and an L-shaped fixing plate is disposed at the upper end of the fixing plate 306. Rotating the threaded rod 304 can drive the fixing plate 306 to move, so that the L-shaped fixing plate above the fixing plate 306 pushes the casing-like ring component coaxially with the rotating platform 2 along the clamping opening 501, and finally fastens it to the bottom edge of the casing-like ring component. Figure 1 As shown. Each set of threaded rods 304 has an inner fixing block 302 passing through one end near the center of the rotating platform 2. At least two sets of threaded rods 304 are coaxially fixedly connected, and a set of bevel gears 305 are coaxially fixed on these two sets of threaded rods 304. The other two sets of threaded rods 304 have opposite thread directions, and bevel gears 305 are fixedly installed at their adjacent ends. Adjacent bevel gears 305 mesh with each other, such as... Figure 4 As shown. When a set of threaded rods 304 rotates, it drives the bevel gear 305 connected to it to rotate. The bevel gear 305 then drives other bevel gears 305 to rotate, realizing the linkage effect of multiple sets of threaded rods 304. This causes multiple sets of fixed clamping plates 306 to converge synchronously along the clamping opening 501, pushing the casing-like ring parts to return to their position and be fixed.
[0023] Furthermore, each set of external fixing blocks 301 is fixedly provided with a pressure guide plate 303 between it and the corresponding internal fixing block 302. The pressure guide plate 303 has an inverted V-shaped cross-section and slides in cooperation with the fixing clamp 306. Figure 3 As shown, the inverted V-shaped pressure plate 303 is used to prevent iron filings from contacting the threaded rod 304, and at the same time, it plays a guiding role for the fixed clamping plate 306. When the fixed clamping plate 306 is subjected to longitudinal external force, the pressure plate 303 can also play a supporting role, reducing the stress on the threaded rod 304.
[0024] A drive mechanism 7 is provided on the support frame 6. The drive mechanism 7 includes an automatic pushing device 701 fixedly connected to the support frame 6, preferably an electric telescopic rod. A motor assembly 702 that slides with the support frame 6 is fixedly provided at the output end of the automatic pushing device 701, and a mating sleeve 703 is fixedly provided at the output end of the motor assembly 702. At least one set of threaded rods 304 passes through the outer fixing block 301, and a mating block 704 that mates with the mating sleeve 703 is coaxially fixedly provided. When it is necessary to move the fixing clamp 306 to fix the bottom of the casing-type ring, or to release the fastening of the bottom of the casing-type ring, the automatic pushing device 701 is activated to push the motor assembly 702 forward, so that the docking sleeve 703 docks with the docking block 704. Then the motor assembly 702 is activated, and through the docking block 704, it drives a set of threaded rods 304 to rotate. In turn, through the bevel gear 305, it drives the four sets of threaded rods 304 to rotate synchronously, thus completing the adaptation and release of the fixing clamp 306 to the bottom edge of the casing-type ring.
[0025] The transmission assembly 9 includes a sleeve 902 fixedly mounted on the upper surface of the rotating platform 2, and a sleeve 901 that slides with the sleeve 902 and is fixedly connected to the bottom of the placement plate 5. The sleeve 902 and the sleeve 901 allow the placement plate 5 to move vertically along the top of the rotating platform 2, facilitating the pushing of the housing-like ring component to the detection area of the rangefinder 8, while also enabling the rotating platform 2 to drive the placement plate 5 to rotate.
[0026] The lifting mechanism 4 includes an automatic lifting device 401, which can be an electric telescopic rod or a hydraulic telescopic rod. A positioning ring 402 is fixedly installed at the output end of the automatic lifting device 401. The placement plate 5 is rotatably fitted inside the positioning ring 402, and a bearing is fitted between the placement plate 5 and the positioning ring 402. Initially, the automatic lifting device 401 drives the placement plate 5 to send the housing-type ring to the detection height. After detection, the automatic lifting device 401 returns the housing-type ring to the fixed clamping plates 306, which then retract and fasten to the bottom of the housing-type ring. Afterward, the automatic lifting device 401 pushes the positioning ring 402, causing the placement plate 5 to move the housing-type ring upward, while the fixed clamping plates 306 fasten to the bottom of the housing-type ring, thereby improving the clamping effect and fixing the housing-type ring.
[0027] An electric baffle 11 is installed on the support frame 6 in front of the rangefinder 8. It opens during testing and closes after testing to prevent debris and coolant from contaminating or damaging the rangefinder 8 during cutting. A limiting block that mates with the clamping port 501 is fixed above the outer fixing block 301. This limiting block is used to limit the placement plate 5 through the clamping port 501 and rotates the placement plate 5 together with the transmission assembly 9. An airflow cleaning assembly can also be installed on one side of the base 1 to intermittently output airflow to the surface of the rotating platform 2 to blow away debris and coolant from the surface of the rotating platform 2.
[0028] In one specific embodiment: This step follows the lifting mechanism 4, which raises the placement plate 5, along with the casing-like ring component, to a height level with the output end of the rangefinder 8. At this point, the rotating platform 2 has started and is driving the ring component to rotate at a constant angular velocity ω. The rangefinder 8 is fixed on the support frame 6, and the horizontal distance L between its measurement reference point and the axis of the rotating platform 2 is a known constant of the device. This constant is obtained by calibration using a laser interferometer after the equipment is assembled and stored in the parameter memory of the adaptive system.
[0029] When the ring rotates at an angular velocity ω, the spatial position of any point P on the outer surface of the ring relative to the measuring reference point of the distance measuring instrument 8 changes periodically with time. The distance measuring instrument 8 continuously collects the straight-line distance data from this point to the distance measuring instrument 8 at a sampling frequency f. This forms the original time-distance sequence.
[0030] Because there is an unknown eccentricity e between the ring axis O' and the axis O of the rotating platform 2, and the outer radius R of the ring is also unknown, the original distance sequence It contains the coupling information between R and e.
[0031] To simultaneously decouple the two independent parameters R and e from the output signal of a single rangefinder 8, a periodic signal decomposition method is adopted: firstly, the acquired distance data... Performing the square operation yields The sequence, under the condition of uniform rotation of the ring, is a periodic signal superimposed with measurement noise, and its period T is equal to the time required for the ring to rotate one revolution. .
[0032] right The sequence is integrally averaged over a complete rotation period to extract its DC component A, which corresponds to... The mean value over a period of time; simultaneously extract The amplitude of the AC component B, which corresponds to The maximum fluctuation amplitude relative to its mean. The extraction of DC component A and AC component B is achieved using the discrete Fourier transform within a single rotating period data window, specifically, for the k-th sampling point... The sequence is subjected to a discrete Fourier transform, and its zero-frequency component is taken as the estimate of the DC component A, and the amplitude of the fundamental frequency component is taken as the estimate of the AC component B.
[0033] Obtaining the DC component A and the AC component B provides two independent observation equations for solving the ring radius R and eccentricity e in the subsequent simultaneous equations.
[0034] Formula ① gives The periodic signal expression form, where the DC component A and AC component B correspond to specific functional combinations of the ring radius R and eccentricity e, respectively. Formula ① is: Where t is a time variable, and its range is... , For one complete rotation cycle; The distance reading output by the rangefinder (8) at time t; ω is the square of the distance reading; ω is the angular velocity of the rotating ring driven by the rotating platform (2); For cosine trigonometric functions; A is The DC component of the sequence within one complete rotation cycle; B is... The amplitude of the AC component of the sequence.
[0035] The physical meaning of formula ① is: the square value of the distance measured by the rangefinder (8). As the ring rotates at a constant speed, its amplitude changes in a cosine periodic manner, with the DC component A and AC component B varying from... Extracted from the sequence. Raw distance data is collected by the rangefinder (8). And recorded as The angular velocity ω is provided by the drive controller of the rotating platform (2) and denoted as ω. Together, they form the input variable in formula ①. With ω. Formula ① The sequence and its DC component A and AC component B are used as inputs for solving the simultaneous equations and are directly used by formula ②.
[0036] Further, this step takes the previously extracted DC component A and AC component B, as well as the known constant L of the device (the horizontal distance from the reference point of the rangefinder 8 to the axis of the rotating platform 2), and establishes a system of simultaneous equations to solve for the ring radius R and eccentricity e. Based on geometric relationships, when the ring axis... When there is an eccentricity e relative to the axis O of the rotating platform, a point P on the outer surface of the ring is rotated at an angle e. The coordinates of the reference point measured by the distance measuring instrument 8 at any given time can be expressed as follows: Where L is the distance from the measuring reference point of the rangefinder 8 to the axis O of the rotating platform 2, e is the eccentricity from the axis O' of the ring to the axis O of the rotating platform, and R is the outer radius of the ring. The square of the distance from this point to the measuring reference point of the rangefinder 8 is... Expandable to Compare with formula ① , can be obtained and Two independent equations. Solve the above two equations simultaneously, letting the intermediate variable... Then the system of equations becomes and Eliminating the intermediate variable C yields information about... The quadratic equation of .
[0037] Formula ② provides the expression for solving the radius R of the ring component, which is determined by the DC component A and AC component B obtained from Formula ①, as well as the device constant L. Formula ② is: Where R is the outer radius of the ring; A is the value defined in formula ①. The DC component of the sequence; B is defined in formula ①. The amplitude of the AC component of the sequence; the physical constraint is A≥B, corresponding to the geometric constraints. (That is, the distance from the measuring reference point of the rangefinder (8) to the axis of the ring is greater than the radius of the ring, ensuring that the rangefinder (8) is always located outside the ring).
[0038] The physical meaning of formula ② is: the radius R of the ring is determined by... The amplitudes of the DC component A and AC component B of the sequence are uniquely determined by the square root operation, and the smaller of the two positive roots of the quadratic equation is selected.
[0039] The DC component A and AC component B obtained by processing the raw distance data collected by the rangefinder (8) through formula ① together form the input variables A and B in formula ②. R in formula ② is used as the input item for confirming the clamping radius and is directly used by formula ④.
[0040] Formula ③ provides the expression for solving the eccentricity e, which is determined by the ring radius R obtained from Formula ②, the AC component B from Formula ①, and the device constant L. Formula ③ is: Where e is the axis of the ring component. The eccentricity relative to the axis O of the rotating platform (2); L is the horizontal distance from the measuring reference point of the rangefinder (8) to the axis of the rotating platform (2); B is the distance defined in formula ①. The amplitude of the AC component of the sequence; R is the outer radius of the ring obtained by formula ②; fraction The physical meaning is an intermediate variable. That is, the distance between the reference point and the axis of the ring is measured by the distance measuring instrument (8).
[0041] The physical meaning of formula ③ is: the eccentricity e is equal to the distance L of the rangefinder (8) minus the ratio of B to 2R, when This indicates that the axis of the ring component is completely aligned with the axis of the rotating platform.
[0042] The constant L obtained from the installation position calibration of the support frame (6), along with R in formula ② and B in formula ①, together form the input variables L, R, and B in formula ③. e in formula ③ serves as the criterion for determining whether the ring component has been aligned and is directly used by formula ⑤.
[0043] Furthermore, this step takes the previously obtained ring radius R and eccentricity e and converts them into drive commands executed by the clamping mechanism. The four sets of clamping components of the adaptive clamping mechanism 3 are evenly distributed around the ring. The threaded rod 304 in each set of clamping components rotates to drive the fixed clamping plate 306 to move radially. The L-shaped fixing plate at the upper end of the fixed clamping plate 306 contacts the outer wall of the ring through the clamping opening 501 on the placement plate 5. The four sets of threaded rods 304 mesh with each other through bevel gears 305, ensuring that the radial displacement of the four sets of fixed clamping plates 306 is strictly consistent. To achieve automatic alignment between the ring and the rotating platform 2, the ring needs to be pushed from its initial eccentric position to a position where the axes coincide, i.e., the eccentricity e is eliminated. The radial movement Δr of the fixed clamping plate 306 is related to the current radius R of the ring and the target clamping radius. The relationship between them is The target clamping radius It should be equal to the radius R of the ring (after clamping, the inner wall of the L-shaped fixing plate fits against the outer wall of the ring), therefore This is the final clamping position. However, in the initial state, the fixing plate 306 is in the maximum open position, and its initial radius... Given the known constants of the device (determined by the geometric layout of the outer fixed block 301 and the inner fixed block 302), the total stroke required for movement is: The lead of the threaded rod 304 is p (unit: mm / r). The relationship between the angle θ that the threaded rod 304 needs to rotate and the displacement Δr of the fixed clamping plate 306 is given by the principle of thread transmission.
[0044] Formula ④ gives the formula for calculating the target rotation angle of the threaded rod 304, which is obtained from the ring radius R and the known initial radius of the device. The value is determined by both the lead p of the threaded rod and the total lead p. Formula ④ is: Where θ is the target angle that the threaded rod (304) needs to rotate; p is the lead of the threaded rod (304); R is the radius of the circle containing the inner wall of the L-shaped fixing plate when the fixing plate (306) is in the maximum open position; R is the outer diameter radius of the ring obtained by formula ②. The total radial displacement required to fix the clamp (306).
[0045] The physical meaning of formula ④ is: for every rotation (360°) of the threaded rod (304), the fixed clamp (306) moves radially by a distance of one lead p, therefore the target angle... equal to the total displacement required Divide by the lead p and then multiply by 360°.
[0046] The lead p is provided by the machining parameters of the threaded rod (304) and denoted as p, and the initial radius is provided by the installation position calibration of the outer fixing block (301) and the inner fixing block (302). And recorded as Together with R in formula ②, they form the input variable p in formula ④. , .
[0047] In formula ④, θ is used as the driving command for the motor assembly (702) and is directly used in formula ⑥.
[0048] Formula ⑤ provides the criteria for determining the alignment state of the ring component, which is jointly determined by the calculated eccentricity e and the preset eccentricity tolerance ε. Formula ⑤ is: Where e is the axis of the ring component. The eccentricity relative to the axis O of the rotating platform (2); ε is the preset eccentricity tolerance threshold; the judgment result of formula ⑤ is a Boolean logic value: when When TRUE is established, it indicates that the ring component has met the alignment requirements, triggering a stop clamping action; when If the condition is not met (FALSE), it means that the ring has not yet met the alignment requirements and the clamping action needs to continue to reduce the eccentricity.
[0049] The physical meaning of Formula ⑤ is: by comparing the current eccentricity e with the preset tolerance ε, it is determined whether the clamping alignment is completed.
[0050] The input variables e and ε in formula ⑤ are formed by e in formula ③ and the preset parameter ε of the adaptive system. The determination result of formula ⑤ serves as the trigger condition for stopping the clamping action, controlling the stopping time of the motor assembly (702).
[0051] Furthermore, this step follows the previously generated target rotation angle θ and centering determination conditions. This is then converted into specific drive parameters for the motor assembly 702. After the motor assembly 702 mates with the mating block 704 via the mating head 703, it drives the threaded rod 304 to rotate. The rotation angle θ is equal to the rotation angle of the output shaft of the motor assembly 702 (the mating head 703 and the mating block 704 have a 1:1 transmission ratio). The rotational speed n (in r / min) of the motor assembly 702 is set by the control parameters of the adaptive system. The drive time required to complete the target angle θ is then determined. The value is determined by the relationship between rotational speed and angle. Simultaneously, the actual displacement of the fixed clamping plate 306 needs to be monitored in real time during the clamping process to ensure that the clamping action is executed accurately.
[0052] To this end, an encoder is integrated into the motor assembly 702 to provide real-time feedback on the actual rotation angle of the motor output shaft. ,when Stop the motor drive when the clamping action is complete. Furthermore, after clamping, it is necessary to verify whether the ring meets the alignment requirements, i.e., verify formula ⑤. Is this valid? Since the position of the ring has changed after the clamping action, the eccentricity e before clamping cannot be directly reused. A secondary detection is needed (rangefinder 8 collects another set of data and executes formulas ①②③) to obtain the eccentricity after clamping. And compare it with ε to confirm successful clamping.
[0053] Formula ⑥ provides the formula for calculating the drive time of motor assembly 702, which is determined by the target rotation angle θ of the threaded rod 304 and the set speed n of motor assembly 702. Formula ⑥ is: in, The driving time required for the motor assembly (702) to complete the rotation of the target angle θ; θ is the target rotation angle of the threaded rod (304) obtained by formula ④; n is the set speed of the motor assembly (702); the coefficient 360 is the number of angles corresponding to each revolution; the dimension of the product 360⋅n is degrees per minute (° / min), which represents the total number of angles rotated by the motor assembly (702) per minute.
[0054] The physical meaning of Formula ⑥ is: when the motor assembly (702) rotates at a speed of n, it rotates 360⋅n degrees per minute. Therefore, the time required to complete a rotation of θ degrees is θ / (360⋅n) minutes. The set speed n, provided by the control parameters of the motor assembly (702), is denoted as n, and together with θ in Formula ④, forms the input variables n and θ in Formula ⑥. As an actual power-on drive duration command for the motor assembly (702), the operating duration of the motor assembly (702) is controlled.
[0055] Technical Effects of this Section: This section establishes a complete closed-loop link from the acquisition of raw distance data by the rangefinder 8 to the generation and execution of drive commands by the motor assembly 702. Through the step-by-step transmission and transformation of formulas ① to ⑥, the physical distance information of the outer surface of the ring component is ultimately converted into synchronous rotation drive signals for each threaded rod 304 of the clamping mechanism. The output of each stage in the entire link is directly used as the input of the next stage, realizing seamless transmission of detection data to execution commands, avoiding manual reading and parameter input, and ensuring the accuracy of the clamping radius setting and the synchronization of the clamping action.
[0056] Working Principle: Initially, the housing-type ring is placed on the placement plate 5. The automatic lifting device 401 moves the placement plate 5 upward, thereby moving the housing-type ring upward away from the adaptive clamping mechanism 3, so that the bottom of the housing-type ring is flush with the output end of the rangefinder 8. The electric baffle 11 on the support frame 6 opens. The rotating platform 2 starts, driving the housing-type ring to rotate. The rangefinder 8 begins to collect relative distance information with the housing-type ring and generates a time-distance curve. By analyzing the rotation period and distance information, the radius of the housing-type ring is calculated. After the detection is completed, the automatic lifting device 401 retracts, moving the placement plate 5 back to its original position, and the fixing clamp 306 extends out from the clamping port 501.
[0057] At this point, the mating block 704 aligns with the mating sleeve 703, and the automatic pushing device 701 pushes the motor assembly 702 forward, causing the mating sleeve 703 at the output end of the motor assembly 702 to align with the mating block 704 on the threaded rod 304. The motor assembly 702 starts, driving a set of threaded rods 304 to rotate via the mating block 704. Since the threaded rods 304 are linked by bevel gears 305, the rotation of this set of threaded rods 304 will drive the other threaded rods 304 to rotate synchronously.
[0058] The adaptive clamping mechanism 3 determines the appropriate clamping radius based on the detected radius. During implementation, the threaded rod 304 rotates, causing the fixed clamping plate 306 on it to move, so that the fixed clamping plate 306 can move according to the detected clamping radius. The L-shaped fixed plate above the fixed clamping plate 306 pushes the casing-like ring along the clamping opening 501 to be coaxial with the rotating platform 2, and finally fastens it to the bottom edge of the casing-like ring, thus achieving the fastening of the casing-like ring.
[0059] Subsequently, the automatic lifting device 401 pushes the positioning ring 402 up slightly, causing the placement plate 5 to move the casing-type ring part upward by a certain distance, while the fixing clamping plate 306 is always fastened to the bottom of the casing-type ring part, further improving the clamping effect and ensuring that the casing-type ring part is stably fixed during the processing.
[0060] After the casing-type ring component is tightened, the cutting assembly 10 above the base 1 begins to machine the casing-type ring component. During the machining process, the rotating platform 2 drives the placement plate 5 and the casing-type ring component to rotate, and the sleeve 902 and sleeve 901 cooperate to keep the placement plate 5 in a stable state. At this time, the electric baffle 11 on the support frame 6 remains closed to prevent the chips and coolant generated during cutting from contaminating or damaging the rangefinder 8.
[0061] After processing, the automatic lifting device 401 moves the placement plate 5 downward, and the automatic pushing device 701 restarts, pushing the motor assembly 702 forward so that the docking sleeve 703 docks with the docking block 704. Then, the motor assembly 702 rotates in the opposite direction, driving a set of threaded rods 304 to rotate in the opposite direction through the docking block 704. Through the linkage of the bevel gear 305, multiple sets of threaded rods 304 rotate synchronously in the opposite direction, driving the fixed clamping plate 306 to move outward. The L-shaped fixed plate moves away from the bottom edge of the casing-like ring, at which point the processed casing-like ring can be removed.
[0062] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
