[0049] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0050] An automatic conveying and tightening assembly machine for a flare support body, such as Figure 1 The figure shows an assembly machine equipped with a rotary conveyor. If the rotary conveyor is not required, the conveyor can be directly Figure 2 The structure shown in the application, the flare support body 10 described in the present invention is the object workpiece for the assembly operation, and the description directly focuses on the flare support body as the workpiece, but the assembly machine of the present invention is not limited to the assembly of the flare support body, and can be applied to the assembly of other workpieces with the same operation requirements. The positional relationship of the structural arrangement of each part of the mechanical device is described in detail below in conjunction with the drawings.

[0051] like Figure 2The automatic conveying and tightening assembly machine for a flare support shown in the figure comprises a machine base 1, a conveying mechanism 2, a clamping and positioning mechanism 3, a tightening mechanism 4 and a measuring device 5. The machine base 1 is configured to have an assembly station for performing assembly work operations, and the conveying mechanism 2, the clamping and positioning mechanism 3, the tightening mechanism 4 and the measuring device 5 are installed on the machine base 1. The conveying mechanism 2 is used to transport the flare support 10 to or away from the assembly station, the clamping and positioning mechanism 3 is used to position and clamp the flare support 10 on the assembly station, the tightening mechanism 4 is used to tighten the flare support 10, and is configured to realize a structural setting for controlling the tightening operation torque, and the measuring device 5 is used to measure the tightening operation depth of the flare support 10, and is configured to follow the structural setting for measuring the depth during the tightening operation, so that the tightening operation process can be monitored in real time in depth.

[0052] The transmission mechanism 2, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a conveying track 21 connected to the machine base 1 corresponding to the assembly station, a pallet trolley 22 running on the conveying track 21, and a trolley driving cylinder 23 arranged on the machine base 1 for driving the pallet trolley 22 to the corresponding assembly station or leaving the assembly station. The pallet trolley 22 is provided with a pallet 24 for placing the flare support 10, which is convenient for the movement of the mechanical automation operation. The pallet 24 is provided with a cylinder positioning seat 241 for positioning and placing the flare support 10 to ensure the stability of the flare support 10 on the pallet 24 during the transmission process. In order to facilitate the smooth overall sliding of the pallet 24 and the flare support 10 during the clamping process, a pallet slide 221 for the pallet 24 to be placed thereon can be fixedly provided on the pallet trolley 22. The side of the pallet 24 is provided with an anti-collision component 242 to provide collision protection when the pallet 24 is moved during the clamping process, play a role in buffering and shock absorption, and avoid shaking or tipping caused by the impact force of rigid collision; the machine base 1 can also be provided with a buffer 25 for the pallet trolley 22 to collide when it is in place, as shown in FIG. Figure 5 As shown, it can also achieve collision protection and play a role in buffering and shock absorption. In this embodiment, since the structural setting of the clamping and positioning mechanism 3 needs to avoid the space required for the transmission mechanism 2 to transmit, the above-mentioned pallet 24 together with the flare support body 10 will slide and move during the clamping process, and the pallet 24 will need to be pushed back to the middle area of ​​the pallet trolley after assembly to ensure stability during the transportation process. Therefore, in this embodiment, the base 1 is provided with a pallet transverse movement mechanism 26 for pushing the pallet 24 to slide to the middle area of ​​the pallet trolley 22, as shown in the figure, including a transverse movement cylinder 261 fixedly installed on the base 1, a push block 262 connected to the piston rod of the transverse movement cylinder 261, and a pallet baffle 263 fixedly set on the base 1 on the opposite side of the push block 262, so as to achieve the above-mentioned push back of the pallet 24.

[0053] Here is a description of how to perform effective clamping and tightening assembly actions to avoid wasting kinetic energy, such as Figure 6 As shown in the figure, the corresponding assembly station on the machine base 1 is provided with a first photoelectric sensor device 61 for detecting the flare holder 10. The device is used to detect whether there is a flare holder 10 on the current pallet trolley. When detected, a signal is sometimes given to control the subsequent clamping action, thereby avoiding invalid actions and reducing action losses.

[0054] The clamping and positioning mechanism 3, such as Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, it includes a fixed clamp block 31 and a movable clamp block 32, which are respectively arranged in two opposite directions of the assembly station, and are arranged on both sides of the conveying track 21 of the corresponding assembly station as shown in the figure. The fixed clamp block 31 is installed on the machine base 1 through a fixed support 311, and a guide positioning structural surface 312 is provided on the side facing the assembly station, which can position the axis of the flare support body 10 when clamping. Here, as mentioned above, the fixed clamp block 31 needs to avoid the space required for the conveying mechanism 2 to convey, so the fixed clamp block 31 is used to position the axis of the flare support body 10 when clamping, which is biased outside the conveying track 21, so as to achieve avoidance. In order to avoid the bottom of the tray 24 being unsupported after moving when clamping due to avoidance, a docking plate 313 that can be docked with the side of the tray trolley 22 is provided below the fixed clamp block 31 shown in this embodiment. As shown in the figure, the movable clamp block 32 is installed on the machine base 1 through a tension sliding seat 321, and the tension sliding seat 321 is slidably connected to the machine base 1 through a tension guide sliding structure 322. The machine base 1 is provided with a clamp block driving cylinder 323 for driving the movable clamp block 32 to move forward and backward relative to the fixed clamp block 31, and the tension movement is driven by the clamp block under the guidance limit of the tension guide sliding structure 322. In order to achieve accurate positioning of the clamping axis and stable clamping, the movable clamp block 32 includes a movable clamp seat 324 and a plurality of movable clamping blocks 325 movably arranged on the movable clamp seat 324, and the plurality of movable clamping blocks 32 5 is a structure that can automatically direct the thrust to the axis of the flare support body 10 during clamping. As shown in the figure, the movable clamping block 325 in this embodiment is a symmetrical two-piece setting, and is respectively hinged on the movable clamp seat 324 through a pin structure 326. Furthermore, the guide positioning structure surface 312 of the fixed clamping block 31 and the side surface combination of the two movable clamping blocks 325 and the guide positioning structure surface 312 are respectively configured as concave semi-cylindrical surfaces, which can be quickly and adaptively adjusted to the state of positioning the axis during the clamping process to clamp. The mechanical structure of this structure is flexible and ingenious, and can accurately locate the axis. In addition, the movable clamping block 325 and the fixed clamping block 31 can be provided with a wear-resistant clamping anti-damage part 327, such as brass or other materials with a lower hardness than the working material, which can reduce the wear on the flare support body 10 during the clamping process. The fixed clamp block 31 of the above structure can accurately position the flare support, while the movable clamp block 32 can make it easier to put the flare support and the tray in place, and can push the flare support to an accurate positioning position, making the operation more flexible.

[0055] The tightening mechanism 4, such as Figure 2 , Fig. 9 and Fig.10As shown, it is installed on the machine base 1 through a tightening support 49 and corresponds to the top of the assembly station, and includes a drive motor 41, a torque sensor 42, a torque limiter 43, a lifting drive cylinder 44, a bearing seat 45, a spline shaft 46, a spline shaft sleeve 47 and a wrench 48; the drive motor 41 (reduction motor) is fixedly installed on the upper end of the tightening support 49, and its output shaft faces downward, the input end of the upper end of the torque sensor 42 is fixedly connected to the output shaft of the drive motor 41, the input end of the upper end of the torque limiter 43 is fixedly connected to the output end of the lower end of the torque sensor 42, the upper end of the spline shaft 46 is fixedly connected to the output end of the lower end of the torque limiter 43, and the bearing seat 45 is fixedly connected to the output end of the spline shaft 46. The seat 45 is fixedly arranged on the tightening support 49, the spline shaft 46 is inserted into the bearing of the bearing seat 45, and the bearing seat 45 fixes the axis of the spline shaft 46 so that it can only rotate along the axis. The spline sleeve 47 is arranged on the tightening support 49 through a linear guide slider 471 and can move up and down. The lower end of the spline shaft 46 is inserted from the upper end of the spline sleeve 47 to form a spline fit that can move up and down. The lifting drive cylinder 44 is fixedly installed on the tightening support 49 through a bracket, and its piston rod is connected to the connecting block set outside the spline sleeve 47. The wrench 48 is fixedly connected to the lower end of the spline sleeve 47 for docking and positioning with the tightening auxiliary parts set on the flare support body 10. The torque sensor 42 can detect the torque value generated during the tightening action, and the torque limiter 43 can limit the maximum torque. When the actual torque value is greater than the set torque value, the torque limiter 43 will be slidably connected so that the torque is no longer transmitted, which is conducive to protecting the safety of the drive motor 41 and over-tightening. When the lifting drive cylinder 44 is working, it will drive the spline sleeve 47 to move up and down under the guidance of the linear guide slider 471. The spline part of the spline shaft 46 cooperates with the spline hole in the spline sleeve 47. When the spline shaft 46 rotates, the wrench 48 can be driven to rotate through the spline sleeve 47. Here, since the spline part of the spline shaft 46 is longer, the spline sleeve 47 can move up and down along the spline part of the spline shaft 46, but it does not hinder the transmission of rotational torque. The tightening auxiliary part provided on the flare support body 10 is used to assist tightening during the tightening process. It is placed first when the flare support body 10 is placed on the tray 24. It has a wrench groove that cooperates with the wrench groove on the flare support body 10 to transmit torque.

[0056] The measuring device 5, such as Figure 2 , Fig.11 and Fig.12As shown, it includes a measuring mounting bracket 501, a measuring lifting drive cylinder 502, an encoder 503, a transmission connecting shaft 504, a synchronous belt mounting plate 505, a synchronous belt 506, a transmission wheel 507, a driven wheel 508, a synchronous belt clamping plate 509, a movable probe rod 510, a movable guide frame 511, an elastic member 512 and a fixed probe rod 513. The measuring mounting bracket 501 is fixedly mounted on the machine base 1, the measuring lifting drive cylinder 502 is mounted on the measuring mounting bracket 501, and its piston rod faces downward. The synchronous belt mounting plate 505 is connected to the measuring lifting drive cylinder 502 or the measuring mounting bracket 501 through a lifting and sliding guide structure, and is connected to the piston rod of the measuring lifting drive cylinder 502. The driving wheel 507 and the driven wheel 508 are correspondingly mounted on the synchronous belt mounting plate 505 from top to bottom. The synchronous belt 506 is wound around the driving wheel 507 and the driven wheel 508. The encoder 503 is installed on the synchronous belt mounting plate 505. The movable guide frame 511 is mounted on the synchronous belt mounting plate 505, and the movable probe rod 510 is vertically movable and can be lifted and lowered through the movable guide frame 511, and the upper end is connected to the synchronous belt clamping plate 509, and the lower end is a probe end 514, which is elastically supported by the elastic member 512 and extends out of the bottom of the movable guide frame 511. As shown in the figure, the elastic member 512 is a spring that is sleeved on the movable probe rod 510 and the upper and lower ends are respectively pressed against the convex rings provided on the movable guide frame 511 and the movable probe rod 510. The bottom of the movable guide frame 511 is fixedly provided with the fixed probe rod 513, which can ensure the maximum retraction of the movable probe rod 510. The fixed probe rod 513 and the probe end 514 are corresponding to the top of the assembly station, so as to contact the flare support body 10 respectively and realize measurement through the movement of the movable probe rod. In the above structure, the driven wheel 508 can be connected to the synchronous belt mounting plate 505 in an adjustable and movable manner through the tension adjustment block 517, so as to facilitate the tension adjustment of the synchronous belt 506. The movable probe rod 510 is fixed to the synchronous belt 506 through the synchronous belt clamp plate 509. When the movable probe rod 510 moves up and down, it will drive the synchronous belt 506 to move, thereby driving the transmission wheel 507 to rotate. When the transmission wheel 507 rotates, it will drive the shaft of the encoder 503 to rotate, so that the value of the encoder 503 changes.

[0057] When used for measurement work, the piston of the measuring lifting drive cylinder 502 extends, driving the synchronous belt mounting plate 505 to descend, and the synchronous belt mounting plate 505 drives the encoder 503, the movable probe rod 510, etc. to descend at the same time. The movable probe rod 510 contacts the upper end surface of the small support body and stops descending. The movable probe rod 510 retracts relative to the movable guide frame 511, and the spring is compressed. The movable probe rod 510 stops descending, which will force the synchronous belt 506 to stop descending, while the measuring lifting drive cylinder 502 continues to extend. At this time, the synchronous belt 506 drives the transmission wheel 507 to rotate, and drives the axis of the encoder 503 to rotate through the transmission connecting shaft 504, thereby bringing about a change in the value of the encoder 503, until the fixed probe rod 513 contacts the upper end surface of the small support body, the movable guide frame 511 stops descending, forcing the synchronous belt mounting plate 505 to stop descending, and the measuring lifting drive cylinder 502 stops extending, and the current value of the encoder 503 is recorded, thereby converting the height position of the small support body of the current flare support body 10, and calculating the torque value required to tighten the flare support body 10, so as to control the work of the above-mentioned tightening mechanism 4. During the tightening process, the tightening drive motor drives the wrench to rotate, and the wrench drives the small support body of the flare support body 10 to be tightened, and the end face of the small support body begins to decline, and the movable probe rod declines under the tension of the spring, driving the synchronous belt to decline, and the value of the encoder also changes accordingly. When the torque value monitored by the torque sensor reaches the predetermined requirement, the tightening drive motor stops working, the wrench stops rotating, the tightening stops, and the movable probe rod also stops declining. The current encoder value is recorded, and the installation depth of the small support body is obtained through conversion. The installation result is judged whether it is qualified by detecting the value. If it is unqualified, the tightening mechanism is activated again, and the measuring device continues to measure. If it is qualified, the measuring device is reset, the wrench of the tightening mechanism rises and resets, and the clamping and positioning device is loosened and reset. The pallet transverse movement mechanism pushes the pallet to slide to the middle area of ​​the pallet trolley, and the conveying mechanism can push the pallet trolley out.

[0058] The rotary conveying device 7, such as Figure 1 and Fig.13As shown, its structure includes a conveyor base 71, a docking track 72, an output conveyor line 73, an input conveyor line 74, a line change toggle mechanism 75, a vehicle loading and unloading mechanism 76 and a vehicle unloading mechanism 77. The docking track 72 is mounted on the conveyor base 71, one end of which is docked with the conveying mechanism 2 for the pallet trolley 22 to reciprocate, and the other end is a loading and unloading station. The output conveyor line 73 is arranged side by side with the input conveyor line 74 and is arranged perpendicular to the docking track 72. The input end of the output conveyor line 73 is connected to the output end of the input conveyor line 74. The output ends are staggered, and the output connection and the input connection are respectively arranged on the two sides adjacent to the loading and unloading stations of the docking track 72.
