Description

Technical Field

[0001] The present invention belongs to the technical field of special devices for processing automotive parts, and particularly relates to a screw fixing block riveting device. Background Art

[0002] Fixing a fixing block to one end of a screw rod in an inseparable manner in the structural systems of automotive parts such as, but not limited to, screw rods in automotive seat adjustment mechanisms, screw rods in automotive steering systems, screw rods in automotive transmission systems, etc. has the following advantages: It can resist vibration and prevent loosening. For example, plastic deformation generated by riveting can better demonstrate excellent long-term vibration resistance compared to thread locking, and is suitable for the high-dynamic load environment of automobiles. It can avoid failures caused by insufficient pre-tightening force in nut fixing; it is lightweight and space-optimized, eliminating additional fasteners, reducing the number and weight of parts, and since the fixing block located at one end of the screw rod occupies relatively little space, it is very suitable for layout in the narrow space of automotive seats; it has the dual advantages of high process efficiency and low cost. For example, high efficiency can be demonstrated by means of a riveting device to meet the requirements of industrialized large-scale production, and the cost is correspondingly reduced; the force transmission is uniform. If riveting is used, the load distribution can be made uniform, stress concentration can be reduced, and the service life can be extended; it improves the appearance, eliminates the risk of abnormal noise and corrosion (such as rust), and is a permanent connection that can be exempt from inspection and maintenance.

[0003] Taking the riveting of a fixing block to the end of a screw rod in the structural system of an automotive seat adjustment mechanism as an example, the current operation method is that an on-line operator manually screws one end of the screw rod into the fixing block at a reasonable position, and then feeds it into the riveting device for riveting. The deficiencies of this operation method are as follows: On the one hand, the operation intensity of the operator is large; on the other hand, it affects the riveting efficiency of the riveting device, has a high idle probability and wastes energy such as electric energy, etc. On the other hand, it is difficult to ensure that the fixing block is always in the same position at one end of the screw rod, because the degree of pre-threading the one end of the screw rod with the fixing block will vary from person to person, and is also related to factors such as the experience, responsibility and even mood of the operator. Therefore, for screw rods of the same batch, there is a problem of consistency in that the fixing blocks cannot be in the same position. Especially when the deviation exceeds the allowable range, the screw rods with riveted fixing blocks will be scrapped. In addition, it is easy for employees to bring some small garbage and impurities on the surface of the screw rod, resulting in abnormal noise and product jamming in the end. Moreover, there is an oil film on the screw rod, and the hygiene of the employees' gloves is not easy to control.

[0004] Since the screw fixing block riveting device belongs to non-standard equipment, there are neither national standards nor industry standards to follow, nor is there universality. Because even for the processing of the same workpiece, different manufacturers often have significant differences in structural design. Based on the foregoing factors, no technical inspiration that can be borrowed can be found in the Chinese and foreign patent and non-patent documents disclosed so far. Summary of the Invention

The front end of the fixed block extraction and release action cylinder lifting arm 22 facing downward is fixed to the upper ends of the pair of lifting arm guide columns 23, and the lower ends of the pair of lifting arm guide columns 23 are slidably engaged with the cylinder body of the aforementioned fixed block extraction and release action cylinder lifting arm driving action cylinder 25. The rear end of the aforementioned fixed block extraction and release action cylinder lifting arm 22 is configured as a horizontal cantilever end. The fixed block extraction and release action cylinder 24 is fixed to the side of the rear end of the fixed block extraction and release action cylinder lifting arm 22 facing downward. The fixed block extraction and release action cylinder 24 has a pair of fixed block extraction and release action cylinder fixed block jaws 241 that close towards each other or repel each other to clamp or release the aforementioned fixed block 10. The fixed block extraction and release action cylinder lifting arm driving action cylinder 25 is fixed to the left side of the fixed block extraction and release action cylinder lifting arm driving action cylinder seat 26. The fixed block extraction and release action cylinder lifting arm driving action cylinder column 251 of the fixed block extraction and release action cylinder lifting arm driving action cylinder 25 faces upward and is fixed to the side of the front end of the aforementioned fixed block extraction and release action cylinder lifting arm 22 facing downward. The aforementioned pair of lifting arm guide columns 23 are respectively located on the front and rear sides of the fixed block extraction and release action cylinder lifting arm driving action cylinder column 251. The longitudinal cross-sectional shape of the aforementioned fixed block extraction and release action cylinder lifting arm driving action cylinder seat 26 is L-shaped, and the lower part is fixed to the aforementioned slider connection fixing plate 21 using cylinder seat connection screws 261; in the use state, the aforementioned fixed block extraction and release action cylinder 24 and the fixed block extraction and release action cylinder lifting arm driving action cylinder 25 are electrically connected to the electrical controller for electrical control.

[0025] As a preferred solution, a lifting arm guide column connection plate 231 is fixed between the upper end faces of the aforementioned pair of lifting arm guide columns 23, so that the front end of the aforementioned fixed block extraction and release action cylinder lifting arm 22 is fixed to the lifting arm guide column connection plate 231, achieving the purpose of enhancing the fixed connection effect. According to professional knowledge, since the fixed block extraction and release action cylinder 24 has a pair of fixed block extraction and release action cylinder fixed block jaws 241, it can be undoubtedly determined that the fixed block extraction and release action cylinder 24 is essentially a jaw action cylinder and is a cylinder, that is, the fixed block extraction and release action cylinder 24 uses a cylinder and is connected by a pipeline to a gas generating device such as an air compressor or a similar device controlled by an electrical controller. The aforementioned fixed block extraction and release action cylinder lifting arm driving action cylinder 25 uses a cylinder and is also connected by a pipeline to the aforementioned gas generating device controlled by an electrical controller.

[0026] Continue to see Figure 1 , the aforementioned fixed block extraction and release actuating cylinder reciprocating displacement driving mechanism 3 includes a slider type rodless actuating cylinder 31 and a slider connection fixing plate reciprocating displacement guiding slide rail 32. The slider type rodless actuating cylinder 31 is electrically connected to the electric controller in the use state and is arranged horizontally on the upward side in front of the aforementioned base 1. The left end and the right end of the slider type rodless actuating cylinder 31 are fixed to the base 1 through slider rodless actuating cylinder fixing seats 312. The slider type rodless actuating cylinder 31 has a rodless actuating cylinder driving slider 311. The slider connection fixing plate reciprocating displacement guiding slide rail 32 is fixed to the base 1 by screws in a state parallel to the length direction of the slider type rodless actuating cylinder 31. And a connection fixing plate slider 321 is arranged on the slider connection fixing plate reciprocating displacement guiding slide rail 32. The connection fixing plate slider 321 and the slider connection fixing plate reciprocating displacement guiding slide rail 32 form a sliding pair. The front end of the aforementioned slider connection fixing plate 21 is fixed to the upward side of the aforementioned rodless actuating cylinder driving slider 311 by screws, and the rear end of the slider connection fixing plate 21 is fixed to the upward side of the aforementioned connection fixing plate slider 321 by screws; the aforementioned fixed block extraction and release actuating cylinder 24, the fixed block extraction and release actuating cylinder lifting arm driving actuating cylinder 25, and the aforementioned slider type rodless actuating cylinder 31 are air cylinders.

[0027] After the above-mentioned vibrating bowl feeds (i.e., "feeds into") the fixing block 10 into the fixing block receiving cavity 172 of the fixing block receiving seat 17 through the vibrating bowl guide groove located at its upper part and reaching the fixing block receiving seat 17, the upper part of the fixing block 10 projects out of the fixing block receiving cavity 172. The lifting arm driving cylinder 25 of the fixing block extraction and release action cylinder works, causing the lifting arm driving cylinder column 251 of the fixing block extraction and release action cylinder to move downward, i.e., displace into the cylinder body, driving a pair of lifting arm guide columns 23 to move downward accordingly. The pair of lifting arm guide columns 23 drive the lifting arm of the fixing block extraction and release action cylinder 22 together with the fixing block extraction and release action cylinder 24 fixed to the lower side of its rear end to move downward through the lifting arm guide column connecting plate 231. At the same time, the fixing block extraction and release action cylinder 24 works to repel its pair of fixing block extraction and release action cylinder fixing block jaws 241 from each other. When the lifting arm of the fixing block extraction and release action cylinder 22 moves downward in place under the drive of the lifting arm driving cylinder column 251 of the fixing block extraction and release action cylinder through a pair of lifting arm guide columns 23, the fixing block extraction and release action cylinder 24 works in the opposite direction to clamp the upper part of the fixing block 10 as the workpiece corresponding to the space between its pair of fixing block extraction and release action cylinder fixing block jaws 241. Then, the above-mentioned lifting arm driving cylinder 25 of the fixing block extraction and release action cylinder works in the opposite direction to make its lifting arm driving cylinder column 251 extend upward, i.e., out of the cylinder body, pushing the lifting arm of the fixing block extraction and release action cylinder 22 together with the fixing block extraction and release action cylinder 24 clamping the fixing block 10 to move upward to the state shown in Figure 1 In this state, the above-mentioned slider type rodless action cylinder 31 (i.e., rodless cylinder) works, driving its rodless action cylinder driving slider 311 to move to the right. At the same time, the above-mentioned connecting fixing plate slider 321 moves to the right along the slider connecting fixing plate reciprocating displacement guide rail 32 in a state of keeping pace with the rodless action cylinder driving slider 311. When moving to the right to a position where the fixing block 10 clamped by the pair of fixing block extraction and release action cylinder fixing block jaws 241 corresponds to the upper part of the above-mentioned fixing block riveting seat 18, the above-mentioned lifting arm driving cylinder 25 of the fixing block extraction and release action cylinder works again, causing the lifting arm of the fixing block extraction and release action cylinder 22 together with the fixing block extraction and release action cylinder 24 to move downward according to the above. When the fixing block extraction and release action cylinder 24 moves downward in place and stops working, the pair of fixing block extraction and release action cylinder fixing block jaws 241 repel each other, thus releasing the clamping of the fixing block 10 and making the fixing block 10 located in the fixing block riveting cavity 181 of the fixing block riveting seat 18. Then, the above-mentioned slider type rodless action cylinder 31 works in the reverse direction until the above-mentioned slider connecting fixing plate 21 and the components arranged with it as the carrier are in Figure 1The position shown. By repeating this process, the fixed block 10 is transferred from the fixed block receiving seat 17 to the fixed block riveting seat 18. The above-mentioned concept that the fixed block extraction and release actuating cylinder 24 descends to the in-place position means that the lower part of the fixed block 10 is seated, that is, supported, within the fixed block riveting cavity 181.

[0028] Continue to see Figure 1 And refer to Figure 3 , the aforementioned fixed block riveting mechanism 4 includes a fixed block riveting actuating cylinder 41, a fixed block riveting actuating cylinder fixed seat 42, a riveting head fixed seat 43, a riveting head 44, a lead screw retaining seat 45, a riveting actuating cylinder fixed seat traction plate 46, a pair of riveting actuating cylinder fixed seat traction plate lifting guide rails 47, and a riveting actuating cylinder fixed seat traction plate lifting actuating cylinder 48. The fixed block riveting actuating cylinder fixed seat 42 is fixed within the wall panel cavity 15 at a position between the opposite sides of the upper parts of the aforementioned front wall panel 12 and the rear wall panel 13. The fixed block riveting actuating cylinder 41 is fixed to the upward-facing side of the fixed block riveting actuating cylinder fixed seat 42 in a longitudinal state at a position corresponding to the left side of the connecting fixing plate 14a on the aforementioned wall panel. The fixed block riveting actuating cylinder column 411 of the fixed block riveting actuating cylinder 41 faces downward and, after passing downward through the fixed block riveting actuating cylinder column relief hole formed in the fixed block riveting actuating cylinder fixed seat 42, is fixed to the riveting head fixed seat 43 through the cylinder column expansion fixing head 4111 formed at the end of the fixed block riveting actuating cylinder column 411. On the front side and the rear side of the upper end of the riveting head 44, there extends a riveting head fixing wing 441 ( Figure 3 marked), and a riveting head fixing wing adjustment bolt hole 4411 penetrating through the thickness of the riveting head fixing wing 441 is formed in the riveting head fixing wing 441. A fixing wing fixing bolt 44111 is provided in the riveting head fixing wing adjustment bolt hole 4411 (see Figure 3),(The fixed wing of the riveting head 441 is fixed to the downward side of the riveting head fixed seat 43 by the fixed wing fixing bolt 44111 of the fixed wing, and the aforementioned riveting head 44 corresponds to the upper side of the aforementioned fixed block riveting seat 18. The screw rod retaining seat 45 is fixed to the downward side of the riveting head fixed seat 43 at a position corresponding to the right side of the riveting head 44 by a set of screw rod retaining seat screws 452 distributed at intervals. A screw rod retaining groove 451 adapted to the aforementioned screw rod 20 is formed at the bottom of the screw rod protection seat 45 and penetrates from the left end to the right end of the screw rod retaining seat 45. The lower edge of the traction plate 46 of the riveting action cylinder fixed seat is fixed to the right side surface of the riveting head fixed seat 43, and the upper part extends upward. A pair of reinforcing bars 461 of the traction plate of the riveting action cylinder fixed seat that are parallel to each other before and after are fixed to the lower left side corresponding to the traction plate 46 of the riveting action cylinder fixed seat. The reinforcing bars 461 of the traction plate of the riveting action cylinder fixed seat are also fixed to the upward side of the aforementioned riveting head fixed seat 43. A pair of lifting guide rails 47 of the traction plate of the riveting action cylinder fixed seat are arranged longitudinally and are parallel to each other before and after. The lower ends of the pair of lifting guide rails 47 of the traction plate of the riveting action cylinder fixed seat are fixed to the left side of the traction plate 46 of the riveting action cylinder fixed seat, and the end faces of the lower ends of the pair of lifting guide rails 47 of the traction plate of the riveting action cylinder fixed seat are in contact with the upward side of the riveting head fixed seat 43. The upper ends of the pair of lifting guide rails 47 of the traction plate of the riveting action cylinder fixed seat respectively form a sliding pair with a pair of lifting guide rail sliders 471 corresponding to each other up and down, and the pair of lifting guide rail sliders 471 are fixed to the right side surface of the connecting fixing plate 14a on the aforementioned wall panel. The lifting action cylinder 48 of the traction plate of the riveting action cylinder fixed seat is longitudinally arranged with its lifting action cylinder column 481 of the traction plate of the riveting action cylinder fixed seat facing downward and is fixed to the right side of the connecting fixing plate 14a on the aforementioned wall panel by a lifting action cylinder fixing strip 482. The end of the aforementioned lifting action cylinder column 481 of the traction plate of the riveting action cylinder fixed seat is fixed to the upper end of a transition connecting piece fixing seat 48111 through a transition connecting piece 4811, and the transition connecting piece fixing seat 48111 is fixed to the front side surface of the aforementioned traction plate 46 of the riveting action cylinder fixed seat by screws; in this embodiment, the aforementioned fixed block riveting action cylinder 41 is an oil cylinder, but an air cylinder can also be used and is electrically controlled and connected to an electrical controller in the use state; in this embodiment, the aforementioned lifting action cylinder 48 of the traction plate of the riveting action cylinder fixed seat is an air cylinder and is also electrically controlled and connected to an electrical controller in the use state.)

[0029] Hypothesis Figure 1When the left end of the lead screw 20 shown in the figure is in place with the fixed block 10 (which will be described in detail later), and when riveting is to be performed, that is, when the fixed block 10 in the riveting cavity 181 of the fixed block and the left end of the lead screw 20 are to be riveted into a non-detachable and integrated state, then first the lifting cylinder 48 of the riveting cylinder fixing seat traction plate works. The piston rod 481 of the lifting cylinder of the riveting cylinder fixing seat traction plate descends, that is, extends out of the cylinder body, and pushes the transition connecting piece fixing seat 48111 downward through the transition connecting piece 4811. Since the transition connecting piece fixing seat 48111 is fixed to the riveting cylinder fixing seat traction plate 46, the riveting cylinder fixing seat traction plate 46 together with the riveting fixing seat 43 is driven to descend by the transition connecting piece fixing seat 48111. The lead screw retaining seat 45 on the downward side of the riveting fixing seat 43 is driven to descend. The lead screw 20 is limited by the lead screw retaining groove 451 at the bottom of the lead screw retaining seat 45, that is, the deviation of the lead screw 20 is avoided. In the above state, the fixed block riveting cylinder 41 works, so that the piston rod 411 of the fixed block riveting cylinder together with the cylinder rod extended fixing head 4111 descends to apply a downward pressure to the above-mentioned riveting head fixing seat 43, so that the fixed block 10 is stressed and undergoes plastic deformation by the riveting head 44, so that the fixed block 10 is fixed to the left end of the lead screw 20 to form a non-detachable or inseparable integrated structure. Before the above riveting, the fixed block positioning mechanism 6 has been in a state of positioning the fixed block 10. After the riveting is completed, the above-mentioned lifting cylinder 48 of the riveting cylinder fixing seat traction plate works in the reverse direction, so that the riveting head fixing seat 43 returns upward to the state shown in the figure. At the same time, the above-mentioned fixed block riveting cylinder 41 also works in the reverse direction to make the piston rod 411 of the fixed block riveting cylinder ascend, in anticipation of the next riveting. The lead screw 20 with the fixed block 10 combined at the left end after the riveting is preferably taken away by the manipulator waiting beside.

[0030] Please refer to Figure 4 And continue to combine Figure 1, the above-mentioned screw rod screwing-in place signal providing mechanism 5 includes a longitudinal column 51, a top column sliding seat 52, a top column 53 and a top column return spring 54. There is a pair of longitudinal columns 51 that are longitudinally parallel to each other on the left and right, and are fixed to the right end of the above-mentioned support plate spacer 1611 at a position corresponding to the position between the above-mentioned screw rod screwing-in fixed block signal collector 16 and the above-mentioned fixed block riveting seat 18. The top column sliding seat 52 is fixed between the tops of a pair of longitudinal columns 51 through a top column sliding seat fixing screw 521. A top column sliding hole 522 that penetrates from the left end to the right end of the top column sliding seat 52 is provided in the length direction of the top column sliding seat 52. The top column 53 is slidably engaged with the top column sliding seat 52 at a position corresponding to the top column sliding hole 522, and a top column rightward movement limit position defining bolt 531 is connected to the left end face 533 of the top column 53. The bolt head 5311 of the top column rightward movement limit position defining bolt 531 corresponds to the left end face of the top column sliding seat 52 and also corresponds to the above-mentioned screw rod screwing-in fixed block signal collector 16. A top column leftward movement limit position defining cap 532 with a diameter larger than the diameter of the above-mentioned top column sliding hole 522 is formed at the right end of the top column 53. The top column leftward movement limit position defining cap 532 corresponds to the right end face of the top column sliding seat 52, and a screw rod top 5321 extends at the central position of the right side face of the top column leftward movement limit position defining cap 532. The top column return spring 54 is sleeved on the above-mentioned top column rightward movement limit position defining bolt 531. The left end of the top column return spring 54 is supported on the left hole wall of the top column sliding hole 522, and the right end is supported on the left end face 533 of the top column 53.

[0031] During the process of the screw rod 20 shown in Figure 1 being displaced to the left under the action of the screw rod fixing block automatic screwing mechanism 9 to be described in detail below, on the one hand, the left end of the screw rod 20 and the screw rod mating threaded hole 101 on the fixing member 10 ( Figure 2On the one hand, there is a spiral fit (as shown), and on the other hand, when the left end of the lead screw 10 completely passes through the threaded hole 101 of the lead screw fit and extends to the left side of the fixed block 10 and pushes the right end face of the lead screw top 5321, the top column 53 and the top column right shift limit bolt 531 are displaced to the left against the reaction force of the top column return spring 54. Since the bolt head 5311 will be displaced to the left, when it is displaced to the extent that it can be detected by the aforementioned lead screw screwed into the fixed block signal collector 16 (photoelectric switch), that is, when it enters the servo wire of the lead screw screwed into the fixed block signal collector 16, the lead screw screwed into the fixed block signal collector 16 will feedback a signal to the electrical controller, and the electrical controller will issue an instruction to stop the operation of the lead screw fixed block automatic screwing mechanism 9. Only in this state will the aforementioned fixed block riveting mechanism 4 rivet the fixed block 10. When the fixed block riveting mechanism 4 returns upward after riveting, the aforementioned lead screw fixed block automatic screwing mechanism 9 works in reverse to release the left end of the lead screw 20. At this time, under the restoring force of the aforementioned top column return spring 54, the top column 53 is displaced to the right, that is, it returns to the initial state.

[0032] The aforementioned fixed block 10 is matched with the aforementioned fixed block support column 1811 through the longitudinal hole 102 of the fixed block on it and shown Figure 2 to ensure that the fixed block 10 is stably located in the fixed block riveting cavity 181.

[0033] Please refer to Figure 2 and in combination with Figure 1 , on the upper rear side of the aforementioned fixed block riveting seat 18, there extends a fixed block riveting seat fixed support plate 183. The aforementioned fixed block positioning mechanism 6 includes a fixed block limiting plate positioning driving cylinder 61 and a fixed block limiting plate 62. The fixed block limiting plate positioning driving cylinder 61 is arranged in a horizontal state on the upward-facing side of the aforementioned fixed block riveting seat fixed support plate 183. The fixed block limiting plate positioning driving cylinder column 611 of the fixed block limiting plate positioning driving cylinder 61 faces forward. The shape of the fixed block limiting plate 62 is an L shape deflected 90° counterclockwise, and one end is fixed to the fixed block limiting plate positioning driving cylinder column 611, and the other end is slidably matched with the upper surface of the fixed block riveting seat 18 at a position corresponding to the aforementioned fixed block limiting card seat sliding groove 182; in this embodiment, the aforementioned fixed block limiting plate positioning driving cylinder 61 is a cylinder and is electrically connected to the aforementioned electrical controller in use.

[0034] When the aforementioned fixed block 10 is located in the fixed block riveting cavity 181 of the aforementioned fixed block riveting seat 18 and is located on or constitutes the fixed block support column 1811 ( Figure 2When in the state of being inside the longitudinal hole 102 of the fixed block and waiting to be riveted by the fixed block riveting mechanism 4, that is, before the fixed block riveting mechanism 4 performs riveting, the positioning driving cylinder 61 of the fixed block limiting plate operates under the positioning driving action of the fixed block limiting plate. The cylinder rod 611 of the positioning driving cylinder 61 of the fixed block limiting plate extends out of the cylinder body and drives the guiding flange 621 (also called "fixed block limiting plate guiding rib") at the lower part of the fixed block limiting plate 62 fixedly connected thereto to move forward along the sliding groove 182 of the fixed block limiting seat (also called "guiding flange guiding groove") to limit the fixed block 10, so as to avoid situations such as the fixed block shaking and deviating during riveting, and ensure the riveting quality of the fixed block riveting mechanism 4 for the fixed block 10 and the left end of the lead screw 20. The aforementioned longitudinal hole 102 of the fixed block is a threaded hole, so that during use, fasteners such as bolts or screws can be screwed into it to fix the lower sliding rail (also called "outer sliding rail") of the vehicle seat slide rail and the vehicle floor together, or the fixed block 10 and the lower sliding rail can be fixed by screwing bolts or screws, and the lower sliding rail is fixed to the vehicle floor by another fastener such as a corresponding bolt. In short, regardless of the fixing method used, the aforementioned longitudinal hole 102 of the fixed block is a hole used to fix the fixed block 10 together with one end of the lead screw 20 to the lower sliding rail of the vehicle seat slide rail.

[0035] Continue to see Figure 1 As mentioned above, the lead screw guiding and supporting mechanism 7 includes a lining plate 71, a lead screw seat fixing frame 72, a lead screw seat fixing frame fixing bottom plate 73, a lead screw horizontal supporting column 74 and a pair of lead screw guiding seats 75.

The shapes of the aforementioned pair of lead screw guiding seats 75 are in an inverted pi shape; the aforementioned pair of lead screw signal collectors 8 are respectively corresponding to the front side and the rear side of the middle part in the length direction of the aforementioned lead screw seat fixing frame 72.

In the use state, the aforementioned pair of lead screw signal collectors 8 are electrically connected to the electrical controller (mentioned above).

[0036] According to professional common sense, the diameter of the lead screw guiding seat cavity on the pair of lead screw guiding seats 75, which is generally U-shaped, that is, the distance between the opposite sides of the cavity walls of the pair of lead screw guiding seat cavities, is adapted to the diameter of the lead screw 20. When the lead screw 20 is placed thereon, signals are collected by a pair of lead screw signal collectors 8 and fed back to the electrical controller, and the electrical controller gives the lead screw fixing block automatic screwing mechanism 9, which will be described below, to work.

The middle part of the clamping cylinder rotation shaft 94 is rotatably supported on the upper part of a pair of transmission shaft bearing seats 9411 through a pair of transmission shaft bearings 941, and the lower part of the pair of transmission shaft bearing seats 9411 is fixed to the aforementioned motor platform 921. The clamping cylinder 95 is fixed to the left end of the clamping cylinder rotation shaft 94. An air inlet 942 for supplying air to the clamping cylinder 95 is provided at the axial center of the clamping cylinder rotation shaft 94, and an air outlet 943 is provided at the left end of the clamping cylinder rotation shaft 94. The aforementioned clamping cylinder 95 corresponds to the right side of the aforementioned screw guiding and supporting mechanism 7. The left side of the clamping cylinder 95 has a set of screw clamping jaws 951 for clamping or releasing the right end of the aforementioned screw 20. The electric cylinder driving motor 96 is fixed to the electric cylinder driving motor transmission box 961, and the electric cylinder driving motor shaft of the electric cylinder driving motor 96 extends into the electric cylinder driving motor transmission box 961 and is in transmission connection with the electric cylinder driving transmission device located in the electric cylinder driving motor transmission box 961. The electric cylinder 97 is arranged in a horizontal lying state, and the right end of the electric cylinder 97 is fixed to the aforementioned electric cylinder driving motor transmission box 961 at a position below the electric cylinder driving motor 96. The left end of the electric cylinder 97 is supported on the aforementioned pallet 91 through an electric cylinder support seat 971. The right end of the electric cylinder column 972 of the electric cylinder 97 extends into the electric cylinder driving motor transmission box 961 and is in transmission connection with the aforementioned electric cylinder driving transmission device. The left end of the electric cylinder column 972 extends out of the cylinder body and is connected to the right end of the cylinder column transition connecting shaft 98 through a cylinder column connecting sleeve 9721.The left end of the cylinder column transition connecting shaft 98 is fixed to the front end of the left and right reciprocating displacement arm 99 of the motor platform.

[0038] In this embodiment, the above-mentioned jaw acting cylinder rotation driving motor 92 and the electric cylinder driving motor 96 are motors with forward and reverse functions; the above-mentioned driving pulley 93a and the driven pulley 93b are synchronous pulleys, and the above-mentioned transmission belt 93c is a synchronous belt; the above-mentioned jaw acting cylinder 95 is a cylinder and is connected to the pneumatic servo controller through pipelines by the above-mentioned air inlet 942 and air outlet 943; the above-mentioned electric cylinder 97 is an electric air cylinder.

[0039] The applicant briefly describes the transmission relationship between the electric cylinder driving motor 96 and the electric cylinder 97 mentioned above. The electric cylinder 97 realizes linear motion through the drive of the electric cylinder driving motor 96. Its core transmission relationship is to convert the rotational motion of the electric cylinder driving motor 96 into linear motion. The electric cylinder driving motor 96 is preferably a servo motor, but the use of a stepping motor or other motors with similar functions is not excluded. Generally, the rotation of the electric cylinder driving motor 96 drives the lead screw to rotate, and the nut on the lead screw moves due to the constraint of the thread shaft, thereby pushing the electric cylinder column 972 of the electric cylinder 97 to move linearly.

[0040] As mentioned above, when the fixed block 10 is located in the fixed block riveting cavity 181 and is positioned by the fixed block positioning mechanism 6, when the manipulator places the screw 20 on the aforementioned screw guide support mechanism 7, a pair of screw signal collectors 8 that form a mutual reflection relationship feed back the signal to the electrical controller, and the electrical controller issues a working instruction to the clamping cylinder rotation drive motor 92 of the structural system of the screw fixed block automatic rotation mechanism 9, and the motor shaft head 922 drives the active transmission wheel 93a, drives the driven transmission wheel 93b through the transmission belt 93c, and the driven transmission wheel 93b drives the clamping cylinder rotation shaft 94 together with the clamping cylinder 95 to rotate. At the same time, since the air inlet 942 and the air outlet 943 are each connected to the electric servo controller controlled by the electrical controller through pipelines, the working air is introduced from the air inlet 942 under the operation of the electric servo controller to cause a group of three screw clamps 951 to be repelled. At this time, the electric cylinder driving motor 96 drives the electric cylinder 97 to work, and the electric cylinder column 972 extends to the cylinder body, that is, to the left, to push the motor platform to reset the arm 99 to the left and right. Since the motor platform to reset the arm 99 to the left and right is fixed to the motor platform 921, the motor platform 921 and the aforementioned clamping cylinder provided on the motor platform 921 are driven to rotate the driving motor 92, and the clamping cylinder 95 also moves leftward with the motor platform 921. Under the operation of the aforementioned clamping cylinder 95, that is, under the action of the aforementioned electric servo controller, the group of screw rod clamping jaws 951 that were previously in the repelling state are closed to clamp the right end of the screw rod 20. As the clamping cylinder rotating shaft 94 drives the clamping cylinder 95 together with the screw rod 20 that is in the clamping state of the group of screw rod clamping jaws 951, the left end of the screw rod 20 is screwed into the screw rod matching threaded hole 101 of the fixed block 10, until the left end of the screw rod 10 extends to the left side of the fixed block 10. When the screw rod is screwed into the fixed block, the signal collector 16 collects the signal, which indicates that the screw rod 20 is screwed into the fixed block 10 to the extent that the process requirement is met, that is, it has been screwed into place. Since the principle or specific process of the screw rod being screwed into the fixed block, the signal collector 16 collecting the signal has been described above, the applicant only makes a supplementary description below. Due to the leftward movement of the motor platform 921, the left end of the screw rod 20 will hit the screw rod top head 5321 of the cap 532 of the leftward limit position of the top column 53, causing the bolt head 5311 to move to the left. The screw rod is screwed into the fixed block signal collector 16 to detect the bolt head 5311 and feed the signal back to the electrical controller. The electrical controller issues a command to stop the clamping cylinder rotation drive motor 92 and the electric cylinder drive motor 96, and a set of screw rod clamps 951 release the clamp on the right end of the screw rod 20. Then, the fixed block riveting mechanism 4 described in detail above implements riveting, causing the fixed block 10 to plastically deform and consolidate with the left end of the screw rod 20.After riveting is completed, the fixed block riveting mechanism 4 moves upward. Specifically, first, the working of the fixed block riveting action cylinder 41 causes the riveting head 44 to move upward, and then the working of the riveting action cylinder fixed seat traction plate lifting cylinder 48 causes the riveting head fixed seat 43 to move upward. Immediately afterwards, the manipulator removes the screw rod 20 with the fixed block 10 riveted thereon. By repeating the description of the action process of each mechanism by the applicant above, the riveting requirements for the required number of blocks 10 and screw rods 20 can be satisfied.

[0041] In summary, the technical solution provided by the present invention makes up for the deficiencies in the prior art, successfully completes the invention task, and truly realizes the technical effects described by the applicant in the technical effects column above.
