[0030] Continue to see Figure 1 The fixed block extraction and release cylinder reciprocating displacement driving mechanism 3 comprises a slider type rodless cylinder 31 and a slider connected fixed plate reciprocating displacement guiding slide rail 32. The slider type rodless cylinder 31 is electrically connected with the electrical controller in use and is horizontally laid on the front upward side of the base 1. The left and right ends of the slider type rodless cylinder 31 are fixed with the base 1 through a slider type rodless cylinder fixed seat 312. The slider type rodless cylinder 31 has a rodless cylinder driving slider 311. The slider connected fixed plate reciprocating displacement guiding slide rail 32 is fixed with the base 1 through screws in parallel with the length direction of the slider type rodless cylinder 31. A connected fixed plate slider 321 is arranged on the slider connected fixed plate reciprocating displacement guiding slide rail 32. The connected fixed plate slider 321 and the slider connected fixed plate reciprocating displacement guiding slide rail 32 form a sliding pair. The front end of the slider connected fixed plate 21 is fixed with the upward side of the rodless cylinder driving slider 311 through screws. The rear end of the slider connected fixed plate 21 is fixed with the upward side of the connected fixed plate slider 321 through screws. The fixed block extraction and release cylinder 24, the fixed block extraction and release cylinder lifting arm driving cylinder 25 and the slider type rodless cylinder 31 are all air cylinders.

[0031] After the fixed block 10 is fed (i.e. "fed into") the fixed block receiving cavity 172 of the fixed block receiving seat 17 by the vibration disc guide groove of the vibration disc, the upper part of the fixed block 10 protrudes out of the fixed block receiving cavity 172. The fixed block extraction and release cylinder lifting arm driving cylinder 25 is operated to make the fixed block extraction and release cylinder lifting arm driving cylinder column 251 move downward, i.e. displace inwardly, to drive the pair of lifting arm guide columns 23 to move downward correspondingly. The pair of lifting arm guide columns 23 drive the fixed block extraction and release cylinder lifting arm 22, which is fixed with the fixed block extraction and release cylinder 24 at the rear downward side, to move downward through the lifting arm guide column connecting plate 231. At the same time, the fixed block extraction and release cylinder 24 is operated to make the pair of fixed block extraction and release cylinder fixed block clamping jaws 241 repel each other. When the fixed block extraction and release cylinder lifting arm 22 is displaced downward to a position through the driving of the pair of lifting arm guide columns 23 by the fixed block extraction and release cylinder lifting arm driving cylinder column 251, the fixed block extraction and release cylinder 24 is reversely operated to make the pair of fixed block extraction and release cylinder fixed block clamping jaws 241 clamp the upper part of the fixed block 10 between them as a workpiece. Then, the fixed block extraction and release cylinder lifting arm driving cylinder 25 is reversely operated to make the fixed block extraction and release cylinder lifting arm driving cylinder column 251 extend outwardly, i.e. upwardly, to push the fixed block extraction and release cylinder 24, which clamps the fixed block 10, and the fixed block extraction and release cylinder lifting arm 22 to displace upwardly to a position shown in Fig. 2.Figure 1 the right, at this time, the aforementioned connecting fixed plate slider 321 is in the same state of displacement as the rodless cylinder driving slider 311, i.e. it is displaced along the slider connecting fixed plate reciprocating displacement guide rail 32 to the right, when it is displaced to the right to the position where the fixed block 10 held by the pair of fixed block extraction and release cylinder fixed block clamping jaws 241 is above the aforementioned fixed block riveting seat 18, the aforementioned fixed block extraction and release cylinder lifting arm driving cylinder 25 works again, and the fixed block extraction and release cylinder lifting arm 22 and the fixed block extraction and release cylinder 24 are lowered according to the aforementioned. When the fixed block extraction and release cylinder 24 is lowered to the position, it stops working, and the pair of fixed block extraction and release cylinder fixed block clamping jaws 241 repel each other, thus releasing the clamping of the fixed block 10 and allowing the fixed block 10 to be in the fixed block riveting cavity 181 of the fixed block riveting seat 18. Then, the aforementioned rodless cylinder 31 works in reverse until the aforementioned slider connecting fixed plate 21 and the components arranged with it as the carrier are in the position shown in the figure. Figure 1 The aforementioned fixed block extraction and release cylinder 24 is lowered to the position, which means that the lower part of the fixed block 10 is supported in the fixed block riveting cavity 181.

[0033] Suppose Figure 1When the left end of the screw rod 20 is to be riveted to the fixed block 10 (to be described in detail later) and the riveting is to be performed, that is, when the fixed block 10 in the fixed block riveting cavity 181 and the left end of the screw rod 20 are to be riveted to be inseparable and to be integrated, first, the riveting cylinder fixing seat traction plate lifting cylinder 48 is operated, the riveting cylinder fixing seat traction plate lifting cylinder column 481 is lowered to extend out of the cylinder body, the transition connecting piece fixing seat 48111 is pushed down through the transition connecting piece 4811, the transition connecting piece fixing seat 48111 is fixed with the riveting cylinder fixing seat traction plate 46, so the riveting cylinder fixing seat traction plate 46 and the riveting fixing seat 43 are driven downward by the transition connecting piece fixing seat 48111, the screw rod holding seat 45 on the lower side of the riveting fixing seat 43 is driven downward by the riveting fixing seat 43, the screw rod 20 is limited by the screw rod holding groove 451 at the bottom of the screw rod holding seat 45, that is, the screw rod 20 is prevented from being deviated. In the above state, the fixed block riveting cylinder 41 is operated, the fixed block riveting cylinder column 411 and the cylinder column expansion fixing head 4111 are lowered to exert downward pressure on the riveting head fixing seat 43, so that the fixed block 10 is forced to be plastically deformed by the riveting head 44, and the fixed block 10 is integrated with the left end of the screw rod 20 to be inseparable or not to be separated. Before the above riveting, the fixed block positioning mechanism 6 has been in the state of positioning the fixed block 10. After the riveting is completed, the above-mentioned riveting cylinder fixing seat traction plate lifting cylinder 48 is reversely operated, the riveting head fixing seat 43 is returned upward to the state shown in the figure, at the same time, the above-mentioned fixed block riveting cylinder 41 is reversely operated to make the fixed block riveting cylinder column 411 go up, expecting the next riveting. The screw rod 20 with the fixed block 10 riveted to the left end is preferably taken away by the mechanical hand waiting on the side.

[0034] Please refer to Figure 4 and continue to combine Figure 1The aforementioned lead screw engagement 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 parallel to each other longitudinally and laterally, and they are fixed to the right end of the aforementioned support plate 1611 at a position corresponding to the position between the aforementioned lead screw engagement fixing block signal collector 16 and the aforementioned fixing block rivet seat 18. The top column sliding seat 52 is fixed between the tops of the pair of longitudinal columns 51 by a top column sliding seat fixing screw 521. A top column sliding hole 522 is formed along the length of the top column sliding seat 52, extending from the left end to the right end.

The bolt head 5311 of the rightward limit position limiting bolt 531 corresponds to the left end face of the top column sliding seat 52 and also corresponds to the aforementioned screw screw into the fixed block signal acquisition device 16. At the right end of the top column 53, there is a top column leftward limit position limiting cap 532 with a diameter larger than the aforementioned top column sliding hole 522. The top column leftward limit position limiting cap 532 corresponds to the right end face of the top column sliding seat 52, and a screw tip 5321 extends from the center of the right side face of the top column leftward limit position limiting cap 532. The top column return spring 54 is sleeved on the aforementioned top column rightward limit position limiting 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 top column left end face 533 of the top column 53.

[0035] In the Figure 1 As the lead screw 20 shown is displaced to the left by the automatic screw fixing block screw-fitting mechanism 9 (which will be described in detail below), the left end of the lead screw 20 engages with the screw threaded hole 101 on the fixing member 10. Figure 2When the left end of the screw rod 10 is fully extended through the screw rod fitting thread hole 101 to the left side of the fixed block 10 and pushes the right end face of the screw rod top head 5321, the top post 53 is displaced to the left against the force of the top post return spring 54, and the bolt head 5311 is displaced to the left. When the displacement reaches a level that can be detected by the screw rod rotation into the fixed block signal collector 16 (optoelectronic switch), i.e., the screw rod rotation into the fixed block signal collector 16 is in the wire, the signal is fed back to the electrical controller by the screw rod rotation into the fixed block signal collector 16, and the electrical controller issues an instruction to stop the operation of the screw rod fixed block automatic rotation fitting mechanism 9. In this state, the fixed block 10 is riveted by the fixed block riveting mechanism 4. When the fixed block riveting mechanism 4 returns upward after riveting, the screw rod fixed block automatic rotation fitting mechanism 9 works in reverse to release the left end of the screw rod 20. At this time, the top post 53 is displaced to the right under the restoring force of the top post return spring 54, i.e., it returns to the initial state.

[0036] The fixed block 10 is fitted with the Figure 2 The fixed block longitudinal hole 102 is matched with the fixed block support column 1811 to ensure that the fixed block 10 is stably positioned in the fixed block riveting cavity 181.

The fixed block positioning mechanism 6 includes a fixed block limiting plate positioning drive cylinder 61 and a fixed block limiting plate 62.

In this embodiment, the fixed block limiting plate positioning drive cylinder 61 is a gas cylinder and is electrically connected with the electrical controller.

The aforementioned fixed block longitudinal hole 102 is a threaded hole, so that in use, a fastener such as a bolt or screw is screwed in to fix the lower slide rail (also referred to as "outer slide rail") of the automobile seat slide rail together with the automobile floor, or the fixed block 10 is fixed with the lower slide rail by screwing in a bolt or screw, and the lower slide rail is fixed with the automobile floor by another fastener such as a corresponding bolt. In summary, regardless of the fixing method used, the aforementioned fixed block longitudinal hole 102 is a hole for fixing the fixed block 10 together with one end of the lead screw 20 and the lower slide rail of the automobile seat slide rail.

When the screw rod 20 is placed thereon, the signals are collected by the pair of screw signal collectors 8 and fed back to the electrical controller, and the electrical controller drives the screw rod fixing block automatic rotation and matching mechanism 9 to be described below to work.

[0042] In the embodiment, the aforementioned clamping jaw action cylinder rotary drive motor 92 and the electric cylinder drive motor 96 are motors with forward and reverse rotation functions; the aforementioned driving transmission wheel 93a and the driven transmission wheel 93b are synchronous pulleys, and the aforementioned transmission belt 93c is a synchronous belt; the aforementioned clamping jaw action cylinder 95 is a gas cylinder and is connected with a pneumatic servo controller through pipelines through the aforementioned gas inlet 942 and the gas outlet 943; the aforementioned electric cylinder 97 is an electric gas cylinder.

[0043] The applicant will briefly describe the transmission relationship between the electric cylinder drive motor 96 and the electric cylinder 97 mentioned above below. The electric cylinder 97 realizes linear motion through the driving of the electric cylinder drive motor 96, and the core transmission relationship is to convert the rotary motion of the electric cylinder drive motor 96 into linear motion. The electric cylinder drive motor 96 preferably adopts a servo motor, but does not exclude the use of a stepper motor or other similar function motor. Generally, the rotation of the electric cylinder drive motor 96 drives the rotation of the lead screw, and the nut on the lead screw moves due to the thread constraint, thereby pushing the electric cylinder column 972 of the electric cylinder 97 to move linearly.

[0044] As aforementioned, in the state that the fixed block 10 is located in the fixed block riveting cavity 181 and positioned by the fixed block positioning mechanism 6, when the lead screw 20 is placed on the aforementioned lead screw guide support mechanism 7 by the mechanical hand, a pair of lead screw signal collectors 8 in a pair of relationship feedback signals to the electrical controller, the electrical controller sends a work command to the clamping jaw cylinder rotation drive motor 92 of the structural system of the lead screw fixed block automatic screwing mechanism 9, the motor shaft head 922 drives the driving transmission wheel 93a, the transmission belt 93c drives the driven transmission wheel 93b, the driven transmission wheel 93b drives the clamping jaw cylinder rotation shaft 94 and the clamping jaw cylinder 95 to rotate. At the same time, since the air inlet 942 and the air outlet 943 are connected by pipelines to the electric servo controller controlled by the electrical controller, a set of three lead screw clamping jaws 951 are repelled by the introduction of working air through the air inlet 942 under the work of the electric servo controller. At this time, the electric cylinder 97 is driven to work by the work of the electric cylinder drive motor 96, the electric cylinder column 972 extends to the left to push the motor platform left-right reciprocating displacement arm 99, since the motor platform left-right reciprocating displacement arm 99 is fixed with the motor platform 921, the motor platform 921 and the aforementioned clamping jaw cylinder rotation drive motor 92 and clamping jaw cylinder 95 arranged on the motor platform 921 are also moved to the left with the motor platform 921, under the work of the aforementioned clamping jaw cylinder 95, that is, under the action of the aforementioned electric servo controller, the previously repelled set of lead screw clamping jaws 951 are closed to clamp the right end of the lead screw 20. With the clamping jaw cylinder rotation shaft 94 driving the clamping jaw cylinder 95 and the lead screw 20 in the clamped state of the set of lead screw clamping jaws 951 rotating, the left end of the lead screw 20 is screwed into the lead screw matching thread hole 101 of the fixed block 10, until the left end of the lead screw 10 extends to the left side of the fixed block 10. When the lead screw into the fixed block signal collector 16 collects the signal, it means that the degree of the lead screw 20 into the fixed block 10 has reached the process requirement, that is, it has been screwed into place. Since the principle or specific process of the lead screw into the fixed block signal collector 16 collecting the signal has been described above, the applicant only makes supplementary description below. Due to the left movement of the motor platform 921, the left end of the lead screw 20 will reach the lead screw top head 5321 of the top column left movement limit position limiting cap 532, the bolt head 5311 will be displaced to the left, the lead screw into the fixed block signal collector 16 will detect the bolt head 5311 and feedback the signal to the electrical controller, the electrical controller will send a command to stop the work of the clamping jaw cylinder rotation drive motor 92 and the electric cylinder drive motor 96, and a set of lead screw clamping jaws 951 will release the clamping of the right end of the lead screw 20, so that the fixed block riveting mechanism 4 described in detail above is implemented to rivet, so that the fixed block 10 is plastically deformed and integrated with the left end of the lead screw 20.After the riveting is completed, the fixed block riveting mechanism 4 is raised, specifically, the riveting head 44 is first raised by the working of the fixed block riveting action cylinder 41, and then the riveting head fixing seat 43 is raised by the working of the riveting action cylinder fixing seat traction plate lifting action cylinder 48. Then, the threaded rod 20 with the riveted fixed block 10 is taken away by the mechanical hand. The action process of each mechanism is repeated as described above to meet the riveting requirements of the required number of blocks 10 and threaded rods 20.

[0045] In summary, the technical scheme provided by the utility model makes up for the shortcomings in the prior art, successfully completes the invention task, and truly realizes the technical effects described in the technical effect column above.
