Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent machining of parts, and particularly relates to an adjustable attitude on-line multi-hole machining device and method. Background Art

[0002] In the field of machining, especially in an automated production line that needs to perform multi-hole machining on workpieces, a single-machine single-process operation mode is usually adopted. The workpiece needs to be repeatedly transferred and positioned between multiple independent devices. This discrete machining process not only results in low production efficiency, but also is prone to positioning errors during the transfer process, affecting the machining accuracy.

[0003] Existing production lines usually adopt a separated machining mode. The workpiece needs to be transferred and positioned multiple times between different workstations, resulting in a long machining cycle and low efficiency. This discrete machining method is difficult to meet the requirements of modern continuous production and severely restricts the overall efficiency of the production line. Secondly, for workpieces that need to change the machining attitude, most existing devices lack an automatic attitude adjustment function and usually require manual intervention or additional devices to complete the attitude conversion, which not only increases the labor cost, but also easily introduces positioning errors. The Korean invention patent with the application number KR1020210079068 discloses an automatic machining device, which includes a main body, a receiving part, a working component, a workpiece library, a setting mechanism, a passivation barrel component, and a rotation driving component. The receiving part is adapted to receive a plurality of workpieces. The setting mechanism takes the workpiece from the workpiece library to the receiving part. The working component is adapted to take the workpiece to the passivation barrel component for processing. The passivation barrel component includes a turning table and a plurality of passivation barrels that move when the turning table rotates. The rotation driving component drives one of the passivation barrels to rotate. This device can achieve automatic processing and improve the processing efficiency.

[0004] However, in terms of multi-hole machining, traditional devices usually adopt the method of machining single holes in sequence, with a long machining time and it is difficult to guarantee the consistency of hole positions. Especially when machining workpieces with symmetric hole positions, this serial machining method seriously affects the production efficiency. In addition, the positioning systems of existing machining devices often lack precise adjustment functions and it is difficult to guarantee the consistency of the machining reference after the workpiece attitude is converted, resulting in the hole position accuracy not meeting the design requirements. Therefore, it is necessary to provide a machining device that can automatically perform continuous hole machining and hole positioning to solve the above problems in this field. Summary of the Invention

[0005] The purpose of the present invention is to provide an adjustable attitude on-line multi-hole machining device and method with high machining efficiency and high positioning accuracy.

[0006] The technical solution adopted by the present invention to achieve the above purpose is as follows: An adjustable attitude on-line multi-hole processing device, comprising: a workpiece having a rod body and a plate body integrally connected; a processing mechanism having a bearing table, a positioning plate and a pressing member, the bearing table being used for supporting the plate body, the positioning plate having a V-shaped groove for positioning the rod body, and the pressing member being used for pressing the rod body; a posture adjusting device having an openable and closable jaw and a rotation driving unit for grasping the rod body and rotating it from a horizontal state to a vertical state and then transferring it to the processing mechanism; and a punching mechanism for punching the positioned plate body.

[0007] Preferably, the posture adjusting device is further used for grasping the processed workpiece and flipping it back to the horizontal state.

[0008] Preferably, an adjustable attitude on-line multi-hole processing device further comprises a conveyor belt and a gripper mechanism. The conveyor belt is used for conveying the workpiece placed horizontally. The gripper mechanism is arranged above the conveyor belt and is used for grasping both ends of the rod body to realize the transfer of the workpiece. The workpiece with a rod body structure is conveyed horizontally on the conveyor belt to the gripper mechanism. The gripper mechanism lifts the workpiece by grasping both ends of the rod body. Subsequently, the jaws of the posture adjusting device grasp the rod body of the workpiece and rotate the workpiece in the horizontal posture to the vertical posture through the rotation driving unit and transfer it to the designated position of the processing mechanism. At this time, the jaws of the posture adjusting device release the rod body. The bearing table forms a longitudinal constraint on the plate body in the horizontal state, and at the same time, the V-shaped groove forms a lateral constraint on the rod body in the vertical state, realizing the preliminary positioning of the workpiece in the processing mechanism. Subsequently, the pressing member presses the rod body in the V-shaped groove, and the punching mechanism punches the plate body on the bearing table. After the workpiece punching process is completed, the posture adjusting device clamps the rod body through the jaws. Subsequently, the pressing member leaves and cancels the pressing of the rod body in the V-shaped groove. At this time, after the posture adjusting device clamps the processed workpiece and transfers it to the gripper mechanism, the workpiece in the vertical posture is rotated to the horizontal posture through the rotation driving unit. The gripper mechanism grasps both ends of the rod body in the horizontal state, realizing the transfer of the workpiece from the posture adjusting device to the gripper mechanism. The gripper mechanism places the workpiece in the horizontal posture on the conveyor belt, completing one processing. The conveyor belt conveys the processed workpiece backward and conveys the next workpiece to be processed to the designated position. The gripper mechanism grasps the workpiece and repeats the above process, realizing automatic feeding, positioning, processing, and discharging of the parts. Through the cooperation of the posture adjusting device with the gripper mechanism and the processing mechanism, the above solution realizes automatic feeding, discharging, and processing of the workpiece. At the same time, during feeding, automatic positioning before processing is realized through workpiece posture adjustment. While realizing automated production, the alignment accuracy is improved, and at the same time, the processing efficiency and processing accuracy are improved. It overcomes the problem of low processing efficiency caused by manual feeding and discharging operations in the prior art, and at the same time reduces the problem that the manual alignment deviation affects the processing accuracy. The V-shaped groove guides the rod body close to the processing mechanism, which is beneficial to reducing the displacement deviation during the process of the posture adjustment device clamping the workpiece and approaching the processing mechanism. At the same time, it is also beneficial to form the posture correction of the rod body by contacting the rod body through the groove surface, improve the positioning accuracy of the workpiece on the processing mechanism, and reduce the possibility of hole processing position deviation.

[0009] Preferably, the posture adjustment device further has a displacement driving unit. The displacement driving unit is connected to the rotation driving unit, and the rotation driving unit is connected to the clamping jaw. The displacement driving unit is used to transfer the rotated workpiece to the processing mechanism.

[0010] Preferably, the displacement driving unit is also used to transfer the processed workpiece to the gripper mechanism, and the gripper mechanism transfers it to the conveyor belt. The displacement driving unit realizes the linear displacement of the rotation driving unit and the clamping jaw as a whole, and cooperates with the rotation driving unit and the clamping jaw to realize the feeding, positioning and discharging of the workpiece.

[0011] Preferably, the plate body has end faces symmetrically distributed on both sides of the rod body. The end faces are vertical planes. Positioning members are symmetrically arranged on the bearing platform. Each positioning member is used to contact the adjacent end face to realize the rotational positioning of the workpiece. After the posture adjustment device clamps the workpiece and releases it on the bearing platform, while the pressing member presses the rod body in the V-shaped groove, it makes the plate body approach the positioning member. Each positioning member realizes the rotational constraint of the plate body through the contacted end face, so as to realize the rotational positioning of the whole workpiece. During the process of the posture adjustment device clamping the workpiece to the processing mechanism, the V-shaped groove performs horizontal displacement constraint on the rod body, cooperates with the positioning member to perform axial rotation constraint on the plate body, and the bearing platform forms axial displacement constraint on the plate body, realizing the precise positioning of the workpiece during the transfer process, without the need for external power to adjust the positioning of the workpiece, greatly improving the positioning efficiency and positioning accuracy of the workpiece, and at the same time reducing the energy consumption of workpiece positioning; while the posture adjustment device realizes the feeding and discharging of the workpiece, by flipping the clamped workpiece and cooperating with the processing mechanism, the comprehensive constraint of the workpiece in six degrees of freedom can be realized, and the precise positioning of the workpiece can be realized. On the one hand, the processing process flow is optimized and the processing efficiency is improved. On the other hand, the layout of the power device for adjusting the processing positioning of the workpiece is reduced, the processing cost is reduced, and at the same time the possibility of deviation during the workpiece punching process is reduced, and the accuracy of the hole opening position on the workpiece is improved.

[0012] Preferably, the positioning member includes a column body. One end of the column body is connected to the bearing platform, and the other end of the column body is rotatably provided with a roller. The rotation axis of the roller is vertical, and the roller can contact the end face on the same side. During the process of the V-shaped groove guiding and positioning the rod body, the end face of the plate body makes sliding contact with the positioning member to generate friction. By forming rolling contact between the roller and the end face, the friction coefficient is reduced, thereby reducing the wear of the end face and the positioning member. On the one hand, the quality of the workpiece is improved. On the other hand, it is avoided that the wear of the end of the positioning member caused by long-term use leads to a decrease in positioning accuracy; The axial pressure generated by the drilling process on the workpiece can force instantaneous sliding between the end face of the plate body and the contact surface of the positioning member. The rolling contact between the roller and the end face can buffer the impact of the drilling force, reduce the instantaneous displacement caused by sliding friction, maintain the positioning stability, thereby reducing the risk of hole position deviation and uneven hole diameter caused by end face sliding, being beneficial to improving the machining consistency of the holes and reducing the rejection rate.

[0013] Preferably, a groove is provided at one end of the cylinder close to the roller. A piston is disposed in the groove in a mating manner. The piston can slide in the groove along the direction close to the end face. A spring for sliding reset is provided at one end of the piston in the groove. A bracket is provided at the other end of the piston. The roller is rotatably connected to the bracket. The pressing member can press the end face against the roller to realize the piston squeezing the spring. During the positioning process where the pressing member presses the rod body in the V-shaped groove, the end face of the workpiece contacts the roller. The roller, under the external pressure, drives the piston to squeeze the spring in the groove until the rod body completely contacts and is pressed in the V-shaped groove. At this time, the spring is in a compressed state. The drilling axial force during the drilling process is transmitted to the roller through the plate body. Compressing the spring through the piston can buffer the impact energy, reduce the rigid collision between the roller and the end face, being beneficial to suppressing the hole diameter deviation caused by high-frequency vibration. The spring in the compressed state, through its pre-tightening force, makes the roller always fit the end face, can compensate for the unevenness error of the workpiece end face, reduces the machining accuracy requirement for the end face before the workpiece is drilled. After the drilling is completed, after the gripper of the posture adjustment device grabs the rod body, the pressing member releases the pressing of the rod body in the V-shaped groove. Subsequently, the posture adjustment device transfers the clamped workpiece to the grasping mechanism through the displacement driving unit. The moment the posture adjustment device clamps the workpiece and leaves the machining mechanism, the pre-ejection of the spring enables the workpiece to instantaneously obtain an initial velocity through the piston, being beneficial to reducing the peak current when the displacement driving unit starts, reducing the winding heating, prolonging the service life of the servo motor, and achieving energy saving at the same time.

[0014] Preferably, the drilling mechanism has at least two drill bits for simultaneously machining hole structures that are symmetrically positioned on the plate body.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The posture adjustment device cooperates with the gripper mechanism to realize automatic and continuous loading and unloading of the workpiece, reducing the inefficiency and insufficient accuracy of manual replacement; The process of the posture adjustment device rotating and transferring the workpiece can realize the positioning of the workpiece, with a low complexity of movement, improving the positioning accuracy and also improving the machining efficiency; The V-shaped groove, positioning member and bearing platform of the machining mechanism realize six-degree-of-freedom constraint on the workpiece, achieving precise positioning before the workpiece is machined without external power adjustment, improving the position accuracy and radial dimension accuracy of the holes; The positioning member relies on the roller elastically connected to consume the misalignment and friction caused by drilling jitter, improving the machining accuracy and reducing part wear.

Specific embodiments

[0018] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments and the accompanying drawings: Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Refer to the attached Figure 1 - attached Figure 6 , an adjustable attitude on-line multi-hole processing device, comprising: a workpiece 1 having an integrally connected rod body 11 and a plate body 12; a processing mechanism 2 having a bearing table 21, a positioning plate 22 and a pressing member 23, the bearing table 21 being used to support the plate body 12, the positioning plate 22 having a V-shaped groove 220 for positioning the rod body 11, and the pressing member 23 being used to press the rod body 11; a posture adjustment device 3 having an openable and closable jaw 31 and a rotation drive unit 32 for grasping the rod body 11 and rotating it from a horizontal state to a vertical state and then transferring it to the processing mechanism 2; and a punching mechanism 4 for punching the positioned plate body 12.

[0020] The posture adjustment device 3 is also used to grasp the processed workpiece 1 and flip it back to the horizontal state.

[0021] It further includes a conveyor belt 5 and a gripper mechanism 6. The conveyor belt 5 is used to convey the horizontally placed workpiece 1. The gripper mechanism 6 is arranged above the conveyor belt 5 and is used to grasp both ends of the rod body 11 to realize the transfer of the workpiece 1. The workpiece 1 with the structure of the rod body 11 is conveyed to the gripper mechanism 6 in a horizontal posture on the conveyor belt 5. The gripper mechanism 6 lifts the workpiece 1 by grasping both ends of the rod body 11. Subsequently, after the clamping jaw 31 of the posture adjustment device 3 grasps the rod body 11 of the workpiece 1, the horizontally placed workpiece 1 is rotated to a vertical posture by the rotation driving unit 32 and is transferred to the designated position of the processing mechanism 2. At this time, the clamping jaw 31 of the posture adjustment device 3 releases the rod body 11. The bearing table 21 supports the plate body 12 in a horizontal state to form a longitudinal constraint, and at the same time, the V-shaped groove 220 forms a lateral constraint on the rod body 11 in a vertical state, realizing the preliminary positioning of the workpiece 1 on the processing mechanism 2. Subsequently, the pressing member 23 presses the rod body 11 in the V-shaped groove 220, and the punching mechanism 4 punches the plate body 12 on the bearing table 21. After the workpiece 1 is punched, the posture adjustment device 3 clamps the rod body 11 by the clamping jaw 31. Subsequently, the pressing member 23 leaves and cancels the pressing of the rod body 11 in the V-shaped groove 220. At this time, after the posture adjustment device 3 clamps the processed workpiece 1 and transfers it to the gripper mechanism 6, the vertically placed workpiece 1 is rotated to a horizontal posture by the rotation driving unit 32. The gripper mechanism 6 grasps both ends of the rod body 11 in a horizontal state, realizing the transfer of the workpiece 1 from the posture adjustment device 3 to the gripper mechanism 6. The gripper mechanism 6 places the horizontally placed workpiece 1 on the conveyor belt 5, completing one processing. The conveyor belt 5 conveys the processed workpiece 1 backward and conveys the next workpiece 1 to be processed to the designated position. After the gripper mechanism 6 grasps the workpiece 1, the above-mentioned process is repeated to realize automatic feeding, positioning, processing, and blanking of parts. Through the cooperation of the posture adjustment device 3 with the gripper mechanism 6 and the processing mechanism 2, while realizing the automatic feeding, blanking, and processing of the workpiece 1, during the feeding period, automatic positioning before processing is realized through the posture adjustment of the workpiece 1. While realizing automated production, the alignment accuracy is improved, and at the same time, the processing efficiency and processing accuracy are improved. It overcomes the problem of low processing efficiency caused by manual feeding and blanking operations in the prior art, and at the same time reduces the problem that the manual alignment deviation affects the processing accuracy. The V-shaped groove 220 guides the rod body 11 close to the processing mechanism 2, which is beneficial to reducing the displacement deviation during the process of the posture adjustment device 3 clamping the workpiece 1 close to the processing mechanism 2. At the same time, it is also beneficial to contact the rod body 11 through the groove surface to form the posture correction of the rod body 11, improve the positioning accuracy of the workpiece 1 on the processing mechanism 2, and reduce the possibility of hole processing position deviation.

[0022] The posture adjustment device 3 further has a displacement driving unit 33. The displacement driving unit 33 is connected to the rotation driving unit 32, and the rotation driving unit 32 is connected to the clamping jaw 31. The displacement driving unit 33 is used to transfer the rotated workpiece 1 to the processing mechanism 2.

[0023] The displacement driving unit 33 is also used to transfer the processed workpiece 1 to the gripper mechanism 6, and the gripper mechanism 6 transfers it to the conveyor belt 5. The displacement driving unit 33 realizes the linear displacement of the overall rotation driving unit 32 and the jaw 31, and cooperates with the rotation driving unit 32 and the jaw 31 to realize the loading, positioning and unloading of the workpiece 1.

[0024] The plate body 12 has end faces 120 symmetrically distributed on both sides of the rod body 11. The end faces 120 are vertical planes. Positioning members 7 are symmetrically arranged on the bearing table 21. Each positioning member 7 is used to contact the adjacent end face 120 to realize the rotational positioning of the workpiece 1. After the posture adjusting device 3 clamps the workpiece 1 and releases it on the bearing table 21, while the pressing member 23 presses the rod body 11 in the V-shaped groove 220, the plate body 12 is brought close to the positioning member 7. Each positioning member 7 realizes the rotational constraint of the plate body 12 through the contacted end face 120, so as to realize the rotational positioning of the whole workpiece 1. During the process of the posture adjusting device 3 clamping the workpiece 1 to the processing mechanism 2, the V-shaped groove 220 performs horizontal displacement constraint on the rod body 11, cooperates with the positioning member 7 to perform axial rotation constraint on the plate body 12, and the bearing table 21 forms axial displacement constraint on the plate body 12, realizing the precise positioning of the workpiece 1 during the transfer process. There is no need for external power to adjust the positioning of the workpiece 1, greatly improving the positioning efficiency and positioning accuracy of the workpiece 1, and at the same time reducing the energy consumption of the workpiece 1 positioning; while the posture adjusting device 3 realizes the loading and unloading of the workpiece 1, by flipping the clamped workpiece 1 and cooperating with the processing mechanism 2, the full six-degree-of-freedom constraint of the workpiece 1 can be realized, realizing the precise positioning of the workpiece 1. On the one hand, the processing process flow is optimized and the processing efficiency is improved. On the other hand, the layout of the power device for adjusting the processing positioning of the workpiece 1 is reduced, the processing cost is reduced, and at the same time, the possibility of offset during the drilling of the workpiece 1 is reduced, and the accuracy of the opening position on the workpiece 1 is improved.

[0025] See the appendix Figure 7 , the positioning member 7 includes a cylinder body 71. One end of the cylinder body 71 is connected to the bearing table 21, and a roller 72 is rotatably provided at the other end of the cylinder body 71. The rotation axis of the roller 72 is vertical, and the roller 72 can contact the end face 120 on the same side. During the guiding and positioning process of the V-shaped groove 220 on the rod body 11, the end face 120 of the plate body 12 is in sliding contact with the positioning member 7 to generate friction. By forming rolling contact between the roller 72 and the end face 120, the friction coefficient is reduced, thereby reducing the wear of the end face 120 and the positioning member 7. On the one hand, the quality of the workpiece 1 is improved, and on the other hand, it is avoided that the wear of the end of the positioning member 7 caused by long-term use leads to a decrease in positioning accuracy; The axial pressure generated by the punching process on the workpiece 1 can force instantaneous sliding between the end face 120 of the plate body 12 and the contact surface of the positioning member 7. The rolling contact between the roller 72 and the end face 120 can buffer the impact of the drilling force, reduce the instantaneous displacement caused by sliding friction, maintain the positioning stability, thereby reducing the risk of hole position deviation and uneven hole diameter caused by the sliding of the end face 120, being beneficial to improving the machining consistency of the holes and reducing the scrap rate.

[0026] One end of the column body 71 close to the roller 72 is provided with a groove 73, and a piston 74 is arranged in the groove 73 in a matching manner. The piston 74 can slide in the groove 73 along the direction close to the end face 120. One end of the piston 74 in the groove 73 is provided with a spring 75 for sliding reset. The other end of the piston 74 is provided with a bracket 76, and the roller 72 is rotatably connected to the bracket 76. The pressing member 23 can press the end face 120 against the roller 72 to realize the piston 74 squeezing the spring 75. During the positioning process of pressing the rod body 11 in the V-shaped groove 220 by the pressing member 23, the end face 120 of the workpiece 1 contacts the roller 72. The roller 72 is under an external pressure and drives the piston 74 to squeeze the spring 75 in the groove 73 until the rod body 11 is completely in contact with and pressed in the V-shaped groove 220. At this time, the spring 75 remains in a compressed state. The drilling axial force during the punching process is transmitted to the roller 72 through the plate body 12. Compressing the spring 75 through the piston 74 can buffer the impact energy and reduce the rigid collision between the roller 72 and the end face 120, being beneficial to suppressing the hole diameter deviation caused by high-frequency vibration. The spring 75 in the compressed state makes the roller 72 always fit the end face 120 through its pre-tightening force, which can compensate for the unevenness error of the end face 120 of the workpiece 1 and reduce the machining accuracy requirement for the end face 120 before punching the workpiece 1. After the punching is completed, after the gripper 31 of the posture adjusting device 3 grabs the rod body 11, the pressing member 23 releases the pressing of the rod body 11 in the V-shaped groove 220. Subsequently, the posture adjusting device 3 transfers the clamped workpiece 1 to the grasping mechanism through the displacement driving unit 33. The moment the posture adjusting device 3 clamps the workpiece 1 and leaves the processing mechanism 2, the pre-ejection of the spring 75 enables the workpiece 1 to obtain an initial velocity instantaneously through the piston 74, being beneficial to reducing the peak current when the displacement driving unit 33 starts, reducing the winding heating, prolonging the service life of the servo motor, and realizing energy saving at the same time.

[0027] The punching mechanism 4 has at least two drill bits 41 for simultaneously machining hole structures with symmetrical positions on the plate body 12.

[0028] An adjustable posture on-line multi-hole machining method includes the following steps Step 1: The gripper mechanism 6 grabs the horizontal workpiece 1; Step 2: The posture adjusting device 3 grabs the workpiece 1 on the gripper mechanism 6; Step 3: The posture adjusting device 3 rotates the grabbed workpiece 1 to the vertical; Step 4: The posture adjustment device 3 places the grasped workpiece 1 into the processing mechanism 2, and positions the workpiece 1 by relying on the V-shaped groove 220 and the positioning member 7; Step 5: The pressing member 23 presses the workpiece 1; Step 6: The punching mechanism 4 performs the punching work; Step 7: After the processing is completed, the pressing member 23 releases the workpiece 1, and the posture adjustment device 3 transfers the processed workpiece 1 to the gripper mechanism 6; Step 8: The gripper mechanism 6 horizontally places the processed workpiece 1 on the conveyor belt 5.

[0029] Embodiment 2: See the appendix Figure 8 - appendix Figure 9 , on the basis of Embodiment 1 of the present invention, the jaws adopt an oppositely-opening and closing structure, and a clamping surface matching with the rod body is provided on the inner side of the jaws, and the clamping surface is an arc surface.

[0030] The clamping surface is provided with a buffer pad 8, and the buffer pad 8 has an outer layer 81 and an inner layer 82. The inner layer 82 is arranged inside the outer layer 81, and a spaced channel is formed between the inner layer 82 and the outer layer 81. The spaced channel is closed at the top, and the inner layer 82 and the outer layer 81 are made of flexible materials.

[0031] The buffer pad 8 forms an isolation between the clamping surface and the rod body, reduces the micro-displacement of the rod body 11 caused by vibration during the instant start and rapid movement of the posture adjustment device 3, reduces the possibility of wall surface damage caused by the jaws 31 clamping the rod body 11, and reduces.

[0032] During the hole machining of the workpiece 1, part of the machining debris remains in the hole, and part of the metal debris falls on the bearing table 21. After the machining is completed, the posture adjustment device 3 clamps and grabs the rod body 11 by the opposite approach of the two jaws 31. During the grabbing process, the channel between the inner layer 82 and the outer layer 81 is squeezed under the relative approach movement of the rod body 11 and the jaws 31, and the gas in the spaced channel is pressed to be discharged from the bottom to form an air curtain and flow downward along the rod body 11, removing the debris attached to the rod body 11. That is, the clamping action of the jaws 31 can realize the shock absorption of the clamping action and the cleaning of the workpiece 1 after machining, and energy saving is achieved compared with the traditional blowing cleaning.

[0033] The air curtain flowing downward along the rod body 11 can act on the bearing table 21 to blow away the debris staying on the bearing table 21, which is beneficial to reducing the influence of this part of the debris on the subsequent positioning accuracy of the workpiece 1 on the bearing table 21, and improving the positioning accuracy and the position accuracy of the hole machining.
