DETAILED DESCRIPTION

[0087] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application.

[0088] In the prior art, there is a long-standing problem of single function of equipment in the field of carbon fiber product processing. Cylinder-shaped and plate-shaped products need to be cut and edged by using special equipment respectively due to the difference in shape, resulting in large production line area and high equipment purchase cost. When an operator needs to alternately process carbon fiber products of different shapes in a certain automobile parts manufacturing workshop, the equipment must be frequently replaced, which not only reduces the production efficiency, but also easily causes processing precision error due to repeated positioning.

[0089] In order to solve the above problems, the research and development team observed that the processing procedures of the two types of products have process similarity, and tried to realize function integration on a single equipment. Through analysis, it was found that the difference in clamping mechanism is the key factor leading to the incompatibility of the equipment. Based on the modular design concept, a rotatable double-station chassis structure is proposed, which divides the two types of clamping mechanisms into two ends. At the same time, a movable processing unit is designed, which can cover the processing area of different stations. This layout not only maintains the compactness of the equipment structure, but also avoids interference between the clamping mechanisms through physical isolation.

[0090] Please refer to Figures 1-4 As shown in the drawings, the present application is a kind of carbon fiber composite material product cutting and edge grinding device, including main support 1, rotating chassis 3, detachable clamping mechanism and mobile processing unit technical scheme. The upper end of the main support 1 is provided with an upper support 6 with a guide carriage 62, the rotating chassis 3 is driven by a rotating motor 2 to realize station switching, and the two ends are provided with chassis mounting groove 31 for mounting cylindrical clamping mechanism 4 and plate type clamping mechanism 5. The cross-moving driving mechanism 7 drives the cutting mechanism 8 and the polishing mechanism 9 to move along the upper support 6, realizing the processing coverage of different stations.

[0091] The main support 1 refers to the frame structure bearing all components of the equipment, and the connection mode of the support column 61 and the guide carriage 62 ensures the stability of the upper structure. The rotating base 3 refers to a bearing platform that can rotate around the shaft, which is driven by a servo motor to achieve precise angle positioning. The standardized interface design of the base mounting groove 31 facilitates quick replacement of the clamping mechanism. The cylindrical clamping mechanism 4 refers to a positioning device with ring clamping function, which is driven by pneumatic or hydraulic drive to fix different diameter workpieces. The plate clamping mechanism 5 refers to a positioning device with planar adsorption function, which realizes double fixation of thin plate workpieces through the cooperation of vacuum chuck 55 and mechanical clamping jaw. The transverse drive mechanism 7 refers to a transmission device that controls the horizontal movement of the machining unit, which can be driven by gear rack or linear motor to ensure precise adjustment of the cutting and grinding position.

[0092] Specifically, the equipment selects the corresponding clamping mechanism according to the type of the machining object during operation. When machining cylindrical workpieces, the rotating base 3 turns the cylindrical clamping mechanism 4 to the machining area, and the transverse drive mechanism 7 drives the cutting saw 86 to cut circumferentially, and then switches to the grinding wheel 91 to complete the corner processing. When machining plate-shaped workpieces, the base is rotated by 180 degrees to make the plate clamping mechanism 5 enter the machining position. After the vacuum chuck 55 adsorbs and fixes the workpiece, the clamping assembly adjusts the clamping range according to the size, the cutting mechanism 8 completes linear cutting along the preset path, and the grinding mechanism 9 trims the cut. The angle switching of the rotating base 3 and the coordinate movement of the transverse mechanism form a spatial cooperation to ensure that the machining tool can accurately reach the working position of different stations.

[0093] Compared with the prior art, the traditional equipment can only process tubular workpieces, while the present scheme can process cylindrical and plate-shaped workpieces simultaneously through the rotatable double-station design. The fixed machining unit in the prior art cannot adapt to multi-form workpieces, and the present scheme uses a mobile machining unit to expand the machining range. The rigid connection between the traditional clamping mechanism and the equipment body makes it difficult to switch, and the present scheme realizes quick disassembly and assembly through standardized interfaces, significantly improving equipment utilization.

[0094] Through the above technical scheme, the present application effectively solves the compatibility problem of multi-form carbon fiber workpiece machining equipment. The double-station design of the rotating base 3 avoids repeated purchase of equipment, the detachable clamping mechanism shortens the tool switching time, and the mobile machining unit ensures the uniformity of machining precision. This scheme is particularly suitable for small-batch and multi-variety production scenarios, and has significant application value in the fields of aerospace part manufacturing and automobile lightweight part machining.

[0095] Please refer to Figures 5-8As shown, the present application further proposes a cutting and grinding device for carbon fiber composite parts, which horizontal movement driving mechanism 7 includes a guide sleeve 71 slidingly connected to the upper portion of the upper support 6, a cross beam connecting plate 72 fixedly connected between the two groups of guide sleeves 71, and two groups of lifting cylinders 73 fixedly installed on the cross beam connecting plate 72 respectively, and the two groups of lifting cylinders 73 are respectively used to drive the cutting mechanism 8 and the grinding mechanism 9 to move up and down.

[0096] Wherein, the guide sleeve 71 refers to the moving part slidingly matched with the upper support 6, which can be realized by a metal sleeve with a linear bearing, and the inner wall of the sleeve is gap matched with the guide rail of the upper support 6 to provide low-friction sliding support for horizontal movement. Wherein, the cross beam connecting plate 72 refers to a rigid structural member connecting the two groups of guide sleeves 71, which can be realized by a welded steel plate or a cast aluminum alloy member, and the span is matched with the spacing of the upper support 6, which is used to keep the synchronous movement of the two groups of guide sleeves 71. Wherein, the lifting cylinder 73 refers to the actuator for driving the cutting mechanism 8 and the grinding mechanism 9 to move vertically, which can be realized by a double-rod cylinder or a servo cylinder, and the cylinder body is fixed on the cross beam connecting plate 72 by bolts, and the output end is rigidly connected with the processing mechanism.

[0097] Specifically, during processing, when the guide sleeve 71 slides horizontally along the upper support 6, the cross beam connecting plate 72 ensures the displacement synchronization of the two groups of guide sleeves 71 through rigid connection, avoiding the inclination of the mechanism caused by unilateral movement. When the processing depth needs to be adjusted, the two groups of lifting cylinders 73 can independently control the lifting height of the cutting mechanism 8 and the grinding mechanism 9. For example, when the cutting mechanism 8 needs to be pressed down to the set depth for cutting operation, the corresponding lifting cylinder 73 pushes the cutting mechanism 8 to move vertically downward, while the grinding mechanism 9 can remain in place or be adjusted to the preset grinding height synchronously. Since the two groups of lifting cylinders 73 are independently driven, the height adjustment of cutting and grinding actions does not interfere with each other, so that the processing adaptation of parts with different thicknesses is realized.

[0098] Compared with the prior art, the cutting and grinding mechanism 9 in the traditional device is usually driven by single-point lifting, which causes linkage error in the height adjustment of the two processing tools. The present scheme controls the cutting and grinding mechanism 9 by independent lifting cylinders 73, which eliminates the position deviation caused by linkage mechanism, and the rigid connection structure of the cross beam connecting plate 72 and the guide sleeve 71 enhances the stability during horizontal movement, avoiding the decline of processing precision caused by deformation of the mechanism.

[0099] By the technical scheme, the cutting mechanism 8 and the polishing mechanism 9 are independently controlled in the horizontal movement and vertical lifting process, so that the two processing tools can accurately adjust the working position according to the shape of the workpiece. For example, when processing a special-shaped workpiece with sudden thickness change, the cutting mechanism 8 can independently adjust the cutting depth without affecting the height setting of the polishing mechanism 9, thereby effectively solving the problem of uneven processing surface or excessive grinding caused by insufficient synchronous adjustment of the traditional equipment.

[0100] Please refer to Figures 5-8 As shown in the drawings, the application further provides that the horizontal movement driving mechanism 7 further comprises a horizontal movement rack 77, a horizontal movement gear 76, a motor seat plate 74 and a horizontal movement motor 75. The horizontal movement rack 77 is fixedly installed on the upper support 6, the horizontal movement gear 76 is in meshing transmission connection with the horizontal movement rack 77, the motor seat plate 74 is fixedly installed on one of the guide sliding sleeves 71, and the horizontal movement motor 75 is fixedly installed on the motor seat plate 74 and has an output end connected with the horizontal movement gear 76, so as to drive the guide sliding sleeve 71 to move horizontally through the meshing transmission between the horizontal movement gear 76 and the horizontal movement rack 77.

[0101] The horizontal movement rack 77 is a straight-line transmission component with continuous tooth profile, which can be made of high-precision hobbing processed alloy steel material, and the tooth surface is hardened to improve wear resistance. The component serves as a transmission reference surface to provide an accurate meshing track for the gear, so as to ensure the straightness of the movement track. The horizontal movement gear 76 is a cylindrical gear matched with the rack, and the tooth profile is ground to reduce transmission noise. The component converts the rotary motion of the motor into linear driving, and realizes non-slip transmission through tooth meshing. The motor seat plate 74 is a mounting base plate for bearing the driving motor, and the bottom is provided with a reinforcing rib to improve rigidity. The component rigidly connects the driving system and the moving component to eliminate the error accumulation of the intermediate transmission link. The horizontal movement motor 75 is a power source for rotating the horizontal movement gear 76, which can be a servo motor or a stepping motor, and the output shaft is directly connected with the gear through a shaft coupling. The component realizes accurate angle control through closed-loop control, thereby controlling the positioning accuracy of the moving component.

[0102] Specifically, when the transverse positions of the cutting mechanism 8 and the polishing mechanism 9 need to be adjusted, the transverse motor 75 drives the transverse gear 76 to rotate. The transverse gear 76 is in meshing transmission with the transverse rack 77 fixed on the upper support 6, converting the rotary motion into linear movement of the guide sleeve 71. Since the motor base plate 74 is directly fixed on the guide sleeve 71, the power output point of the driving system is rigidly connected with the moving part, avoiding the elastic deformation problem of the traditional belt or chain transmission. During the meshing of the gear and the rack, the rolling contact between the tooth surfaces reduces the friction loss, and the precise matching of the tooth shapes ensures the stability of the transmission process. When the guide sleeve 71 slides along the upper support 6, the linear bearings inside it form double guidance with the support columns 61, effectively suppressing lateral deviation. This transmission mode can still maintain stable meshing state under the high-frequency vibration working condition generated during carbon fiber material processing, avoiding positioning misalignment caused by vibration.

[0103] Compared with the prior art, the traditional cutting and edging equipment usually uses a lead screw transmission to realize transverse movement adjustment. The lead screw transmission has the problems of large axial gap and low transmission efficiency, and is prone to return error when frequently reversing. The gear and rack transmission has the characteristics of gapless meshing, and can maintain position synchronization when transmitting in forward and reverse directions, and is especially suitable for scenes that need to repeatedly adjust the processing position. In addition, the lead screw transmission is prone to bending deformation in long-stroke applications, affecting the movement accuracy, while the rack can be expanded to any length by segmenting and splicing, and is more suitable for the layout requirements of large-span equipment. Compared with the cylinder driving mode used in the prior art, the present scheme realizes stepless speed regulation and precise positioning through motor driving, which can adapt to the processing needs of different sizes of workpieces.

[0104] Through the above technical scheme, the present application effectively solves the problem of insufficient driving stability of the cutting mechanism 8 and the polishing mechanism 9 during transverse movement. The gear and rack meshing transmission eliminates the gap error of the traditional transmission mode, ensuring the repeat positioning accuracy of the processing position adjustment. The cooperation of motor driving and rigid connection structure enables the moving part to still operate stably when subjected to the vibration load generated during carbon fiber processing. This design realizes the precise positioning of the cutting and polishing assembly in the transverse dimension, enabling the equipment to adapt to the processing needs of workpieces of different sizes and shapes, and improving the consistency of processing quality.

[0105] Please refer to Figures 5-8As shown, the present application further proposes a cutting mechanism 8 of the carbon fiber composite part cutting and edge grinding device, which comprises a rodless cylinder 81, a longitudinal moving support 82, a longitudinal moving guide rail 83, a longitudinal moving slide 84, a cutting saw 86 and a driving motor one 85. The rodless cylinder 81 is fixedly installed on the output end of the lifting cylinder 73 and is installed parallel to the upper support 6, the longitudinal moving support 82 is fixedly installed on the output end of the rodless cylinder 81 and is installed perpendicular to the upper support 6, the longitudinal moving guide rail 83 is fixedly installed on the lower end of the longitudinal moving support 82, the longitudinal moving slide 84 is slidingly installed on the longitudinal moving guide rail 83, the cutting saw 86 is rotatably installed on the longitudinal moving slide 84 through a connecting shaft, and the driving motor one 85 is fixedly installed on the longitudinal moving slide 84.

[0106] Wherein, the rodless cylinder 81 refers to an execution element for realizing linear motion by driving a piston through compressed air, which can be realized by adopting a magnetic coupling type or a mechanical type rodless cylinder 81, and realizes compact transverse movement by eliminating the piston rod structure of the traditional cylinder. The longitudinal moving support 82 refers to a support structure for bearing the longitudinal moving assembly, which can be formed by welding aluminum alloy profiles, and forms a three-dimensional guide frame through vertical installation. The longitudinal moving guide rail 83 refers to a linear guide component with high-precision sliding surface, which can adopt a ball linear guide rail or a sliding bearing type guide rail, and ensures the longitudinal moving precision through pre-tightening force adjustment. The longitudinal moving slide 84 refers to a sliding component cooperating with the guide rail, which can be formed by casting cast iron or welding steel plates, and realizes low-friction sliding through the cooperation of V-shaped groove and guide rail. The driving motor one 85 refers to a power device directly driving the rotary cutter, which can adopt a servo motor or a variable frequency speed regulation motor, and eliminates the transmission gap through the direct connection of the shaft coupling and the main shaft of the cutting saw 86.

[0107] Specifically, the lifting cylinder 73 drives the rodless cylinder 81 to adjust the position in the vertical direction, and the rodless cylinder 81 moves transversely along the upper support 6 to adjust the horizontal cutting position of the cutting saw 86. The longitudinal moving support 82 serves as a rigid support for longitudinal adjustment, and realizes the precise positioning of the cutting saw 86 along the length direction of the part through the cooperation of the longitudinal moving guide rail 83 and the longitudinal moving slide 84. The driving motor one 85 directly drives the cutting saw 86 to rotate at high speed, and through the three-dimensional linkage of the transverse movement of the rodless cylinder 81, the longitudinal sliding of the longitudinal moving slide 84 and the vertical adjustment of the lifting cylinder 73, the cutting saw 86 can adjust the position in multiple degrees of freedom according to the shape of the part. When processing special-shaped parts, the longitudinal moving slide 84 slides along the guide rail to change the cutting depth, the rodless cylinder 81 moves transversely to compensate for the cutting path deviation, and the lifting cylinder 73 adjusts the contact pressure of the cutter and the part, forming a composite motion trajectory of the space coordinate system.

[0108] Compared with the prior art, the traditional cutting device only uses a single-axis moving platform to realize linear cutting, and cannot meet the processing needs of complex-shaped workpieces. The scheme realizes composite motion compensation of horizontal and vertical directions through the cooperative control of the rodless cylinder 81 and the longitudinal sliding frame 84, and solves the problem of cutting path deviation caused by the insufficient motion dimension of the traditional device. In the prior art, the cutting depth adjustment depends on manual positioning, and the scheme realizes digital and accurate control of the cutting depth through the cooperation of the guide rail sliding frame and the driving motor.

[0109] Through the above technical scheme, the present application realizes accurate position adjustment of the cutting mechanism 8 in three-dimensional space, can automatically adjust the cutting path according to the workpiece contour, and effectively solves the position deviation problem during the processing of special-shaped workpieces. The digital control of the cutting depth avoids the precision loss caused by manual adjustment, and the multi-dimensional motion compensation mechanism ensures the forming quality of the complex cutting trajectory. The direct connection structure of the driving motor and the cutting saw 86 eliminates the slipping phenomenon existing in the traditional belt drive, and guarantees the stable output of the cutting power.

[0110] Please refer to Figures 5-8 As shown in the figure, the present application further puts forward that the cutting mechanism 8 further comprises a longitudinal moving pulley 88, a transmission belt 89, a longitudinal moving motor 87 and a belt transmission block 841. Among them, the longitudinal moving pulley 88 is provided with two groups and is rotatably installed at the inner sides of the two ends of the longitudinal moving support 82, the transmission belt 89 is drivingly connected between the two groups of longitudinal moving pulleys 88, the longitudinal moving motor 87 is fixedly installed on the longitudinal moving support 82 for driving the longitudinal moving pulley 88 to rotate, and the belt transmission block 841 is fixedly installed on the transmission belt 89 at the upper part and fixedly installed on the longitudinal sliding frame 84 at the lower part. The mechanism of the polishing mechanism 9 is the same as that of the cutting mechanism 8, and a polishing wheel 91 for edge polishing of the workpiece is installed on the connecting shaft at the polishing mechanism 9.

[0111] Among them, the longitudinal moving pulley 88 refers to a rotating part for building a closed-loop transmission system, which can be realized by an aluminum alloy pulley, and the design of being placed at the two ends of the longitudinal moving support 82 can maintain the stability of the tension of the transmission belt 89. The transmission belt 89 refers to a flexible connecting piece for transmitting power, which can be realized by a synchronous belt structure, and the rigid connection with the belt transmission block 841 can avoid motion transmission error. The longitudinal moving motor 87 refers to the power source for driving the transmission system, which can be realized by a stepping motor, and the speed control can realize millimeter-level adjustment of the longitudinal position. The belt transmission block 841 refers to a transition part connecting the transmission belt 89 and the longitudinal sliding frame 84, which can be realized by a split steel sliding block, and the upper and lower split structure can prevent the transmission belt 89 from bearing lateral load. The polishing wheel 91 refers to a grinding tool instead of the cutting saw 86, which can be realized by a diamond-coated grinding wheel, and the common connecting shaft with the cutting mechanism 8 can maintain the consistency of the machining reference.

[0112] Specifically, when the longitudinal movement motor 87 drives the longitudinal movement pulley 88 to rotate, the transmission belt 89 forms a closed-loop motion trajectory between the two sets of longitudinal movement pulleys 88. When the belt transmission block 841 moves linearly with the transmission belt 89, it drives the longitudinal movement carriage 84 to slide accurately along the longitudinal movement guide rail 83. This transmission method eliminates the gear backlash and screw backlash, achieving high-precision positioning of the cutting saw 86 in the longitudinal direction. The grinding mechanism 9 completely replicates the structural layout of the cutting mechanism 8, so that the cutting and edging modules are symmetrically arranged on the transverse movement driving mechanism 7. When switching between processing modes, only the corresponding module needs to be moved to the processing position by the transverse movement driving mechanism 7, and the two tools can maintain the same coordinate reference due to structural consistency.

[0113] Compared with the prior art, the traditional cutting equipment mainly uses a screw or a gear and rack to realize longitudinal adjustment, which has positioning errors caused by transmission gaps. The present scheme eliminates the influence of mechanical transmission gaps on precision through a synchronous belt closed-loop transmission system. In the prior art, the cutting and grinding mechanism 9 often uses independent driving systems, resulting in complex equipment structure and difficulty in unifying the processing reference. The present scheme uses a structural reuse design concept to make the two processing modules share the same motion control system, which simplifies the equipment structure and ensures the consistency of the processing reference.

[0114] Referring to Figures 9-12 As shown in the drawings, the present application further proposes a cylindrical clamping mechanism 4, which includes a cylindrical clamping base 41, a cylindrical sleeve 45, a cylindrical clamping assembly 48, and a bearing support 42. The cylindrical clamping base 41 is fixedly installed in cooperation with the base mounting groove 31 of the rotating base 3, the cylindrical sleeve 45 serves as a clamping main body support, the cylindrical clamping assembly 48 is symmetrically arranged on both sides of the sleeve, and the bearing support 42 is arranged on the upper end of the base to support the sleeve.

[0115] The cylindrical clamping base 41 is an installation base with a standardized interface, which can be implemented by a metal base plate with a positioning pin hole. It is quickly positioned and connected with the pre-installed mounting groove on the rotating base 3, and the clamping mechanism can be disassembled as a whole. The cylindrical sleeve 45 is a cylindrical structure with an axial through hole, which serves as a guide channel for inserting the workpiece. The cylindrical clamping assembly 48 is a clamping unit with radial adjustment function, which can be implemented by a mechanical structure with pneumatic drive and wedge-shaped transmission. The center of the workpiece is positioned by synchronous action on both sides. The bearing support 42 is a support component with a rolling bearing, which can be implemented by a combination structure of double-row angular contact ball bearings and cast iron housings. It can bear the weight of the sleeve while allowing it to rotate freely.

[0116] Specifically, after the cylindrical workpiece is inserted into the sleeve, the two clamping assemblies are moved synchronously to the center, and the workpiece is fixed on the axis of the sleeve by bidirectional force. The bearing support 42 not only bears the static load of the sleeve, but also allows the sleeve to drive the workpiece to rotate and position during processing. When it is necessary to switch the processing object, the entire clamping mechanism can be quickly disassembled through the chassis mounting slot 31, and replaced with a plate-type clamping mechanism 5. The clamping assemblies symmetrically arranged on both sides of the sleeve can independently adjust the clamping distance, and stable clamping can be achieved by adjusting the clamping jaw stroke.

[0117] Compared with the prior art, the traditional clamping device mainly adopts a one-way pressing or three-jaw chuck structure, and there is a problem of eccentric clamping leading to a decrease in processing accuracy. The scheme ensures that the axis of the workpiece coincides with the processing reference by the bidirectional symmetric clamping design, and the modular base structure realizes the quick replacement of different types of clamping mechanisms. Compared with the fixed clamping tool, the rotatable sleeve structure enables the workpiece to adjust the circumferential position during processing, avoiding the efficiency loss caused by repeated clamping.

[0118] Through the above technical scheme, the application effectively solves the problem of unstable clamping of cylindrical workpieces caused by diameter differences. Through the cooperation of the detachable base and the bidirectional clamping assembly, the clamping mechanism can be quickly switched to adapt to the processing needs of workpieces of different specifications. The bidirectional synchronous clamping mechanism can ensure the processing accuracy of cutting and polishing operations. The rotating support structure enables each part of the workpiece to be covered by the processing equipment, avoiding the processing blind area caused by traditional fixed clamping.

[0119] Please refer to Figures 9-12 As shown in the figure, the application further proposes that a sleeve ring plate 46 is fixedly arranged on the outer periphery of the cylindrical sleeve 45, the sleeve ring plate 46 is rotatably installed in the inner ring of the bearing support 42 through a bearing, and a driven gear 47 is fixedly installed on the sleeve ring plate 46; a driving motor two 43 is fixedly installed on the bearing support 42, a driving gear 44 is fixedly installed on the output end of the driving motor two 43, and the driving gear 44 is in meshing transmission connection with the driven gear 47; the driving motor two 43 drives the driving gear 44 to rotate, the driven gear 47 and the cylindrical sleeve 45 are driven to rotate through gear meshing transmission, so as to drive the workpiece to rotate, adjust the relative position of the workpiece and the cutting mechanism 8 and the polishing mechanism 9, and ensure the circumferential comprehensive processing of the cylindrical workpiece.

[0120] The sleeve ring plate 46 refers to an annular plate-shaped structure arranged around the outer wall of the cylindrical sleeve 45, which can be fixed with the cylindrical sleeve 45 by welding or bolt connection, and is used to form a rotatable connection between the cylindrical sleeve 45 and the bearing support 42. The bearing mounted in the inner ring of the bearing support 42 can be a deep groove ball bearing or a tapered roller bearing, which is used to support the sleeve ring plate 46 to realize low-friction rotation. The modulus of the driven gear 47 and the driving gear 44 needs to be matched, and the gear ratio is set according to the speed requirement. The driving motor two 43 can be a servo motor or a stepper motor, which is connected with the driving gear 44 through a reducer to realize precise angle control.

[0121] Specifically, the driving motor two 43 drives the driving gear 44 to rotate after starting, the driving gear 44 meshes with the driven gear 47 to transmit power to the sleeve ring plate 46, the sleeve ring plate 46 rotates in the bearing support 42 through the bearing, and then drives the cylindrical sleeve 45 and the clamped workpiece to rotate synchronously. The rotation angle of the workpiece can be accurately controlled by the number of revolutions of the driving motor two 43. When the cutting mechanism 8 and the polishing mechanism 9 remain in a fixed position, the rotation of the workpiece makes different circumferential regions of the workpiece enter the machining area in turn, realizing 360-degree machining without dead angle. The gear transmission system has self-locking characteristics, can stop at any angle and keep the position stable, avoiding angle deviation caused by vibration during machining.

[0122] Compared with the prior art, the traditional carbon fiber pipe machining equipment usually adopts a fixed clamping method, and the workpiece angle needs to be manually adjusted or the tool position needs to be moved during machining, which has the problems of low machining efficiency and poor precision consistency. The present scheme realizes automatic rotation of the workpiece during machining by integrating a gear-driven rotary clamping mechanism, which can complete full circumferential machining without interrupting the machining process, significantly improving the degree of automation. Gear transmission has higher positioning accuracy than belt or chain transmission, avoiding cumulative error caused by transmission slip.

[0123] Through the above technical scheme, the technical problem of repeatedly disassembling and adjusting the angle of the cylindrical workpiece during cutting and edge grinding is solved, and continuous rotary machining of the workpiece in the clamped state is realized. The circumferential surface of the workpiece can be completely covered by the cutting mechanism 8 and the polishing mechanism 9, eliminating the machining blind area caused by manual intervention and improving the machining quality consistency. The integrated design of rotary drive and clamping function simplifies the equipment structure and reduces the time cost of multi-process conversion.

[0124] Please refer to Figures 9-12As shown, the application further proposes that the cylindrical clamping assembly 48 comprises a pushing cylinder 481, a pushing link plate 482, a wedge-shaped slider 483, a transmission wedge block 484, a clamping arc plate 485, a guide column 486, a spring link plate 488, and a reset spring 487. The pushing cylinder 481 is arranged in multiple groups and fixedly installed on the sleeve ring plate 46 in a ring array, the pushing link plate 482 is fixedly installed on the output end of the pushing cylinder 481, and the side wall of the cylindrical sleeve 45 is provided with a sleeve sliding groove 451 in sliding fit with the pushing link plate 482. The wedge-shaped slider 483 is fixedly connected to the pushing link plate 482 and slides against the inner wall of the cylindrical sleeve 45, the transmission wedge block 484 is in sliding fit with the wedge-shaped slider 483 and fixedly arranged with the clamping arc plate 485 on one side close to the center of the cylindrical sleeve 45. The guide column 486 slides through the side wall of the cylindrical sleeve 45, one end of which is fixedly connected to the clamping arc plate 485, and the other end is fixedly connected to the spring link plate 488. The reset spring 487 is sleeved on the outer periphery of the guide column 486, one end of which is fixedly connected to the outer wall of the cylindrical sleeve 45, and the other end is fixedly connected to the spring link plate 488.

[0125] Among them, the pushing cylinder 481 refers to an execution element driven by compressed gas to output a straight line motion, which can be realized by a double-acting cylinder, and its ring array arrangement can provide uniformly distributed driving force. The sleeve sliding groove 451 refers to a linear guide structure opened in the side wall of the cylindrical sleeve 45, which can be realized by a rectangular cross-section groove, used to limit the sliding direction of the pushing link plate 482. The wedge-shaped slider 483 refers to a sliding part with an inclined contact surface, which can be realized by a 45-degree inclined metal block, which converts axial motion into radial motion through inclined surface contact. The transmission wedge block 484 refers to a driven part cooperating with the wedge-shaped slider 483, which can be realized by a metal block with a complementary inclined surface structure, used to transmit clamping force. The clamping arc plate 485 refers to a clamping part with an arc-shaped contact surface, which can be realized by an aluminum alloy plate coated with polyurethane, used to fit the surface of the cylindrical workpiece. The guide column 486 refers to a cylindrical rod with a linear guide function, which can be realized by a chromium-plated steel rod, used to constrain the radial motion trajectory of the clamping arc plate 485. The reset spring 487 refers to a helical compression spring providing elastic reset force, which can be realized by stainless steel material, used to automatically reset the clamping arc plate 485 when the cylinder retracts.

[0126] Specifically, when the workpiece needs to be clamped, multiple sets of push air cylinders 481 are synchronously extended to push the push connecting plate 482 to slide along the sleeve sliding groove 451 in the axial direction. The push connecting plate 482 drives the wedge-shaped sliding block 483 to move in the axial direction along the inner wall of the cylindrical sleeve 45, and the inclined surface thereof is in contact with the transmission wedge block 484 to generate a radial component force, which pushes the clamping arc plate 485 to move towards the center until the clamping arc plate 485 contacts the surface of the workpiece. When the diameter of the workpiece changes, the stroke of the air cylinder is automatically adjusted to keep each clamping arc plate 485 in uniform contact pressure. The guide column 486 maintains the linear motion of the clamping arc plate 485 during sliding to avoid uneven clamping caused by deflection. After processing is completed, the air cylinder is retracted, and the return spring 487 pulls the guide column 486 back to the original position through the spring connecting plate 488, thereby driving the clamping arc plate 485 to separate from the surface of the workpiece.

[0127] Compared with the prior art, the conventional clamp usually adopts a single clamping point or a manual adjustment mechanism, and has the problems of uneven clamping force distribution and low adjustment efficiency. The scheme realizes multi-point self-adaptive clamping by synchronously driving multiple air cylinders in combination with a wedge-shaped transmission structure, solves the problem of clamping stability of workpieces with different diameters, and has the advantages that, compared with the clamp adopting a threaded adjustment mechanism, the scheme realizes rapid switching of the clamping state by cooperation of a pneumatic driving and an elastic return mechanism.

[0128] Through the above technical scheme, the scheme realizes rapid self-adaptive clamping of a cylindrical workpiece, ensures that workpieces with different diameters can obtain uniformly distributed clamping force during processing. The synchronous radial motion of the clamping arc plate 485 avoids workpiece deformation caused by local stress concentration, and the combined design of the guide column 486 and the return spring 487 ensures accurate resetting of the clamping mechanism. The independent control function of multiple air cylinders can adapt to the clamping requirements of irregular cross-section workpieces, and improves the universality and processing safety of the clamp.

[0129] Referring to FIG. 5, Figures 13-14 As shown in FIG. 5, the plate-shaped clamping mechanism 5 further comprises a plate-shaped base 51 matched with the base mounting groove 31, a motor support 52 fixedly installed at the center of the upper end of the plate-shaped base 51, a driving motor three 53 fixedly installed on the motor support 52, a motor groove 512 arranged at the center of the upper end of the plate-shaped base 51, a turntable bottom plate 54 fixedly installed at the output end of the driving motor three 53, suction cups 55 evenly installed on the turntable bottom plate 54, two sets of plate-shaped clamping assemblies 56 symmetrically arranged around the turntable bottom plate 54 as the center, and base mounting grooves 511 arranged at both ends of the plate-shaped base 51 for installing the plate-shaped clamping assemblies 56. The driving motor three 53 drives the turntable bottom plate 54 to rotate to adjust the processing orientation of the workpiece, the plate-shaped clamping assemblies 56 clamp the unprocessed side, and the suction cups 55 and the clamping assemblies form double fixation.

[0130] The plate-shaped base 51 refers to a mounting base with a positioning pin, which can be formed by machining an aluminum alloy casting into a boss structure matching the installation groove of the rotating base plate 3, and is quickly disassembled and assembled through bolts. This structure makes the clamping mechanism modular, making it easy to switch clamps according to the shape of the workpiece. The motor support 52 refers to a vertical support structure, which can be formed by welding a steel frame into a box structure, with internal cooling channels for fixing the driving motor three 53 and dispersing the rotating torque. The driving motor three 53 refers to a rotating drive device with precise angle control function, which can be a servo motor with encoder, and the output end is connected to the rotating disc bottom plate 54 through a flange to realize multi-angle positioning of the workpiece machining surface. The rotating disc bottom plate 54 refers to a circular bearing platform, which can be an anodized aluminum plate with vacuum holes on the surface, connected to the external vacuum pump through the internal air channel to form negative pressure adsorption. The suction cup 55 refers to a flexible adsorption element, which can be a bowl-shaped vacuum suction cup 55 made of silica gel, evenly distributed on the surface of the rotating disc bottom plate 54 to form an adsorption array, and can realize the pre-positioning of the thin plate workpiece in the early stage of machining. The plate-shaped clamping assembly 56 refers to an adjustable mechanical clamping device, which can be a connecting rod mechanism driven by a bidirectional screw 562, and the screw block 563 moves towards the screw to drive the clamping support plate 569 to move horizontally, adapting to the lateral fixation of workpieces of different sizes.

[0131] Specifically, when the plate-shaped workpiece is placed on the rotating disc bottom plate 54, the vacuum pump is started to generate negative pressure adsorption force on the suction cup 55, preliminarily fixing the workpiece on the bearing surface. At this time, the two groups of plate-shaped clamping assemblies 56 adjust the distance between the clamping support plates 569 according to the size of the workpiece, and mechanically clamp the unprocessed areas on both sides of the workpiece. During cutting or grinding, the driving motor three 53 rotates the rotating disc bottom plate 54 to a specific angle according to the machining program instructions, so that the edge to be machined is aligned with the cutting mechanism 8. When the processing surface needs to be switched, the clamping assembly first releases the current clamping state, and then re-clamps the new unprocessed area after the rotating disc is rotated into position. This combination of static and dynamic fixing methods ensures rigid constraint during machining and avoids interference during rotation. The suction cup 55 continuously provides adsorption force during rotation to prevent displacement of the thin plate workpiece due to centrifugal force.

[0132] Compared with the prior art, the traditional carbon fiber plate workpiece machining equipment mainly uses a single mechanical clamp for fixation, which cannot realize direction adjustment during machining. The present scheme realizes multi-surface machining of the workpiece in a fixed state through the cooperation of the rotating base plate 3 and the rotatable clamping mechanism, avoiding positioning errors caused by repeated disassembly. The existing clamping device lacks a combined fixation mechanism of vacuum adsorption and mechanical clamping, which is prone to vibration and displacement during high-speed machining. The design forms a double fixation through the distributed adsorption of the suction cup 55 array and the rigid constraint of the clamping assembly, effectively suppressing the vibration phenomenon during thin plate machining.

[0133] By the above technical scheme, multi-angle continuous processing of the plate-shaped carbon fiber product is realized, and the problems of the traditional equipment that cannot be compatible with the plate clamping and the insufficient processing stability are solved. The synergistic effect of the suction cup 55 adsorption and the mechanical clamping ensures the positioning accuracy of the product when the processing surface is switched by rotation. The precise angle control of the driving motor cooperates with the adjustable design of the clamping assembly, so that the same device can adapt to the multi-process processing needs of plate pieces of different sizes. The combination of the rotation function and the double fixing mechanism significantly improves the processing efficiency and reduces the waste rate.

[0134] Referring to Figures 13-14 As shown in the drawings, the plate-shaped clamping assembly 56 further comprises a clamping motor 561 rotatably installed on the base mounting groove 511 and having opposite screw threads on both sides, a bidirectional screw rod 562 fixedly installed on the plate-shaped base 51 for driving the clamping motor 561 to rotate, two groups of screw rods 563 symmetrically installed on the clamping motor 561, a moving carriage 565 slidingly arranged on the base mounting groove 511, a plurality of carriage guide rails 566 fixedly arranged at the bottom of the base mounting groove 511, two groups of transmission connecting rods 564 symmetrically rotatably installed on the moving carriage 565, a clamping cylinder 567 fixedly installed on the moving carriage 565, and a lifting connecting plate 568 connected to the output end of the clamping cylinder 567 and a clamping support plate 569.

[0135] The bidirectional screw rod 562 refers to a transmission rod with a positive and negative thread structure, which can be implemented by using a trapezoidal thread screw rod. The transmission connecting rod 564 refers to a hinged rod connecting the slider and the carriage, which can be implemented by using a stainless steel connecting rod cooperating with a joint bearing. The carriage guide rail 566 refers to a guide rail arranged at the bottom of the base mounting groove 511, which can be implemented by using a linear guide rail cooperating with a slider assembly. The clamping support plate 569 refers to a metal pressing plate with a non-slip pattern, which can be implemented by using an aluminum alloy material with a rubber pad inlaid on the surface.

[0136] Specifically, when the clamping motor 561 drives the bidirectional screw rod 562 to rotate, the two groups of screw rod sliders 563 move synchronously and oppositely under the action of the positive and negative threads. The transmission connecting rod 564 converts the linear motion of the slider into the horizontal displacement of the moving carriage 565, and the carriage guide rail 566 restricts the movement of the carriage along the predetermined track. The clamping cylinder 567 drives the lifting connecting plate 568 to drive the clamping support plate 569 to vertically press down, and the product is fixed through multi-point contact. When the processing direction is switched, the clamping motor 561 reverses to drive the screw rod slider 563 to move backward, the transmission connecting rod 564 drives the moving carriage 565 to slide outward, and the clamping support plate 569 is separated from the processing area. The carriage guide rail 566 maintains the movement track of the carriage to avoid positioning errors caused by deviation.

[0137] Compared with the prior art, the conventional plate-shaped clamping mechanism 5 adopts a fixed clamping jaw, which cannot adapt to different sizes of workpieces and is prone to interference with the tool during rotation. The scheme realizes dynamic adjustment of the clamping position through the combination of the bidirectional screw rod 562 and the transmission connecting rod 564, which not only ensures the stable clamping of workpieces of different sizes, but also actively avoids the machining path when the machining direction is switched. Compared with a single pneumatic clamping jaw, the mechanical linkage structure has higher position control accuracy.

[0138] Through the above technical scheme, the present application can adapt to the clamping needs of different sizes of plate-shaped workpieces, automatically adjust the clamping position when the workpiece is rotated to switch the machining direction, avoid interference between the clamping mechanism and the machining tool, and improve the clamping stability through multi-point distributed compression to ensure that the workpiece does not displace during high-precision machining.

[0139] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the scope of the present patent.
