[0033] like Figure 1 As shown, the new type of skateboard line rotary table of the utility model mainly consists of a rotary table running track 1, a rotary table centering device 2, a driven running wheel assembly 3, a rotating frame 4, a rotary drive 5, a rotary table positioning device 6, a movable end block 7, a rotary table in-position control device 8, a skateboard friction drive 10, a skateboard positioning mechanism 11, a skateboard running support roller assembly 12, a skateboard guide groove 13, a skateboard in-position control device 14, and a movable end block opening device 15.

[0034] The new skateboard line rotary table of the present invention also includes an electrical and pneumatic drag chain system 9, which is installed on the ground and fixed by chemical bolts, with one end of the drag chain installed on the rotating frame 4 and the other end installed on the drag chain bracket.

[0035] The turntable centering device 2 is installed at the center of the turntable running track 1, and the turntable running track 1 is connected to the turntable centering device 2 through a connecting plate. Specifically, the turntable centering device 2 is installed on the ground, fixed by chemical bolts, and connected to the turntable running track 1 through a connecting plate.

[0036] The driven wheel assembly 3 is mounted on the turntable's rotating frame 4. The rotating frame 4 is supported by the driven wheel assembly 3 and rotates about the turntable's centering device 2. The driven wheel assembly 3 is bolted to the rotating frame 4. The rotating frame 4 is hingedly connected to the turntable's centering device 2 via a bearing seat. A slide support roller assembly 12, a slide guide groove 13, and a slide friction drive 10 are mounted on the upper surface of the rotating frame 4. Specifically, they are bolted to the rotating frame 4. The slide support roller assembly 12 provides support for the slide, while the guide groove 13 provides guidance. The slide friction drive 10, mounted on the rotating frame 4, controls the slide's movement on the turntable. The slide position control device 14 controls the slide's position on the turntable and its start and stop. The slide position control device 14, mounted on the rotating frame 4, controls the slide's position on the turntable based on sensor feedback signals. The rotation drive 5 is mounted outside the turntable's centering device 2. The friction generated by the friction wheels of the rotation drive 5 drives the rotating frame 4, driving the entire turntable. Specifically, the drive unit 5 is mounted on the ground and secured with chemical bolts. It is not connected to the rotating centering device 2. A slide positioning mechanism 11 is mounted on the rotating frame 4 to position the slide. A turntable positioning device 6 is also mounted on the ground to ensure the accuracy of the turntable's stop position. Specifically, the turntable positioning device 6 is secured to the ground with chemical bolts. Movable end stops 7 are mounted on both ends of the rotating frame 4 to prevent the slide from detaching from the turntable due to a malfunction. The movable end stops 7 are bolted to the rotating frame 4.

[0037] In the present invention, the turntable walking track 1 is made of 8 steel plates and is equipped with a connecting plate connected to other components. The positions of other related components can be aligned by laying out the lines once, and no secondary laying out is required, which facilitates on-site installation. Adjustment gaskets are also provided under the track, and the track height and horizontality can be adjusted by increasing or decreasing the number of gaskets.

[0038] The driven walking wheel assembly 3 includes four main and driven wheel assemblies and eight auxiliary support wheel assemblies. The main and driven wheel rotating shafts are fixed to their main and driven wheel wheel boxes through clamping plates, and the auxiliary support wheel rotating shafts are fixed to their auxiliary support wheel wheel boxes through clamping plates, which can facilitate the disassembly and assembly of the wheels. By removing the clamping plates, the wheels and the rotating shafts can be taken out as a whole, which is convenient for wheel maintenance operations.

[0039] The rotating frame 4 consists of a rotating frame, a rotating main frame and a skateboard friction drive mounting frame. The rotating main frame is connected to the rotating frame and the skateboard friction drive mounting frame by bolts, which is convenient for processing and transportation; the rotating main frame, the rotating frame and the skateboard friction drive mounting frame are all equipped with lifting bolts for facilitating the disassembly of the driven wheel assembly, which is convenient for the repair and maintenance of the driven wheel.

[0040] like Figure 2As shown, the rotary drive 5 comprises a clamping wheel 501, a rotating shaft 502, a bracket 503, a support 504, a floating slide 505, a friction wheel 506, a drive motor 507, a motor mounting plate 508, a rotary shaft 509, a friction wheel positive pressure adjustment device 510, a positive pressure adjustment device support 511, a roller follower 512, a roller follower support 513, a linear guide rail 514, and a base plate 515. The friction wheel positive pressure adjustment device 510 comprises a butterfly spring 510a and an adjustment nut 510b. The rotary drive 5 employs a floating structure to overcome manufacturing and assembly errors of the rotating frame 4. A spring adjustment device is also provided to adjust the positive pressure of the drive wheel, thereby varying the friction between the drive wheel and the rotating frame, thereby ensuring smooth operation of the drive device.

[0041] The clamping wheel 501 is fixed to a bracket 503 via its rotating shaft 502. The bracket 503 is connected to a support 504, which is mounted on a floating slide 505. The friction wheel 506 is mounted on the shaft of a drive motor 507 via a locking sleeve. The drive motor 507 is mounted on a motor mounting plate 508, which is embedded with an oil-free bushing and hinged to a rotating shaft 509. The motor mounting plate 508 can rotate around the center of the rotating shaft 509, thereby driving the entire drive motor 507 and the friction wheel. The friction wheel positive pressure adjustment device 510 is floatingly connected to the motor mounting plate 508. By adjusting the butterfly spring 510a via an adjusting nut 510b, positive pressure is generated between the friction wheel and the rotating frame 4, generating friction to drive the entire rotating frame 4. The rotating shaft 509 is mounted on the floating slide 505. The friction wheel positive pressure adjustment device 510 is mounted on a positive pressure adjustment device support 511, which is in turn mounted on a floating slide 505. The roller follower 512 is mounted on a roller follower support 513, which is supported below the motor mounting plate 508 to prevent the drive motor from sinking eccentrically. The roller follower support 513 is mounted on the floating slide 505. The floating slide 505 is connected to the base plate 515 via linear guides 514. The floating slide 505 can float back and forth on the linear guides 514, thus achieving a floating function for the entire rotary drive device, overcoming the effects of manufacturing and installation errors in the rotating frame 4 and ensuring smooth operation of the rotary table.

[0042] like Figure 4 As shown, in order to ensure the accuracy of the turntable rotation and repeat positioning, a turntable positioning device 6 is added. The turntable positioning device 6 is mainly composed of a docking device 61 installed on the rotating frame 4, a positioning slide 62, a positioning plate guide wheel 63, a guide wheel rotating shaft 64, a driving cylinder 65, a switch trigger 66, a base I 67, a positioning plate extended into position sensor 68 and a positioning plate retracted into position sensor 69.

[0043] The positioning slide 62 is hingedly connected to the piston rod of the drive cylinder 65. The positioning plate guide wheel 63 is embedded with an oil-free bushing and connected to the guide wheel rotating shaft 64. The guide wheel rotating shaft 64 is fixed to the base I 67, and the positioning plate guide wheel 63 can rotate around the center of the guide wheel rotating shaft 64. The switch trigger 66 is mounted on the positioning slide 62. The positioning plate extension sensor 68 and the positioning plate retraction sensor 69 are respectively mounted on the base I 67. The drive cylinder 65 is mounted to the base I 67 via its own hinged seat, and the base I 67 is mounted on the ground. The piston rod of the drive cylinder 65 drives the positioning slide 62 to move back and forth, inserting it into the positioning docking device 61 mounted on the turntable rotating frame to achieve turntable positioning. The positioning plate extension sensor 68 and the positioning plate retraction sensor 69 are triggered by the switch trigger 66 to provide feedback on the positioning plate's status. The positioning plate guide wheel 63 limits the left and right movement of the positioning slide 62 and prevents damage to the cylinder piston rod due to radial forces.

[0044] When the turntable rotates to the right position, the cylinder of the ground positioning device extends out to drive the positioning slide to insert into the positioning docking device installed on the turntable rotating frame, so that the turntable position is fixed to ensure the smooth operation of the slide and the accuracy of the rotation and repeated positioning. Figure 5 As shown, the turntable is equipped with a turntable position control device 8 for controlling the turntable to position. The turntable position control device 8 mainly consists of a deceleration switch trigger 81, an in-position switch trigger 82, an over-travel switch trigger 83, a deceleration proximity switch 84, an in-position travel switch 85, an over-travel travel switch 86 and a limiter 87.

[0045] The deceleration switch trigger 81, in-position switch trigger 82, and overtravel switch trigger 83 are all symmetrically mounted on the same side of the rotating frame 4. The deceleration proximity switch 84, in-position limit switch 85, overtravel limit switch 86, and limiter 87 are all mounted on the turntable track 1. The deceleration proximity switch 84 provides feedback to the PLC, which controls the motor to decelerate, thereby slowing the turntable. The in-position limit switch 85's in-position sensor provides feedback to the PLC, which controls the motor to stop, thereby stopping the turntable. The overtravel limit switch 86 is a turntable protection device and a redundant switch that prevents damage to the mechanical structure caused by excessive turntable rotation if the in-position sensor is damaged. When the turntable reaches its in-position, the deceleration switch trigger 81 first contacts the deceleration proximity switch 84, reducing the turntable speed. The in-position switch trigger 82 then contacts the in-position limit switch 85, stopping the turntable. When the turntable reaches its in-position, the deceleration switch trigger 81 and the deceleration proximity switch 84 are not in contact, and the distance between the trigger and the sensor is approximately 20 mm. The normal detection range of the proximity sensor is 40 mm. This means that the sensor will provide feedback when metal is less than 40 mm from the sensor. The overtravel release trigger 83, overtravel travel switch 86 and limiter 87 are protective devices to prevent the turntable from being damaged due to failure of the in-place switch. The overtravel switch is a turntable protection device and a redundant switch to prevent the turntable from over-rotating and causing damage to the mechanical structure after the in-place sensor is damaged. When the turntable in-place switch is damaged, the overtravel switch trigger installed on the turntable will contact the overtravel switch; if the overtravel switch is damaged, the rotating frame will contact the limiter to prevent damage to the turntable mechanical structure and thus protect the turntable mechanical mechanism. Figure 6 As shown, the rotating frame 4 is equipped with a slide positioning mechanism 11 for positioning the slide. This mechanism 11 utilizes a connecting rod mechanism, with the opening and clamping actuation performed by a pneumatic cylinder. The mechanism 11 primarily comprises a clamping arm I 111, a clamping arm II 112, an articulated shaft 113, a connecting rod 114, an articulated shaft mounting base 115, a pneumatic cylinder 116, a cylinder support 117, a base II 118, a clamping position switch 119, and an opening position switch 120.

[0046] The clamping arm I 111 and clamping arm II 112 are connected to the hinge axis mounting base 115 via an articulated shaft 113. Each clamping arm I 111 and clamping arm II 112 can rotate around the center of the articulated shaft 113. Clamping arm I 111 is hinged to the piston rod of a cylinder 116. Clamping arm II 112 is connected to clamping arm I 111 via a connecting rod 114. The articulated shaft mounting base 115 is mounted on a base II 118. The cylinder 116 is connected to a cylinder support 117 via its own articulated base. The clamping position switch 119 and the opening position switch 120 are mounted on base II 118. The cylinder support 117 is mounted on base II 118, which is in turn mounted on the rotating frame 4. The slide positioning mechanism 11 achieves clamping and opening by driving the piston rod of the cylinder 116 to move the clamping arm I 111 and controlling the state of the clamping arm II 112 via the connecting rod 114. The clamping position switch 119 and the opening position switch 120 are triggered by the state of the clamping arm I 111 to provide feedback on the states of the clamping arm I 111 and the clamping arm II 112 .

[0047] The slide plate positioning mechanism 11 drives the connecting rod mechanism through the cylinder to clamp the slide plate, thereby fixing the slide plate.

[0048] Working principle:

[0049] When the slide, driven by the slide friction drive 10, moves along the slide support roller assembly 12 in the direction of the arrow and enters the turntable, the slide is stopped by the slide position control device 14 mounted on the rotating frame 4. The slide positioning mechanism 11 clamps the slide, and the turntable positioning device 6 retracts. The rotary drive 5 begins to operate, directly driving the rotating frame 4 and its mounted components. During the rotation process, the movable end stop 7 remains in the "block" position due to gravity. After rotating 90° to the desired position, the movable end stop 7 is lifted by the movable end stop opening device 15 mounted on the ground, extending the turntable positioning device 6. The slide positioning mechanism 11 opens, and the slide becomes movable. The slide is driven by the slide friction drive 10 to move the turntable. The deceleration and positioning of the entire rotation process are controlled by feedback signals from the turntable positioning control device 8. The deceleration trigger mounted on the rotating frame 4 triggers the deceleration switch to feedback signals to the PLC, which controls the motor deceleration, thereby slowing down the turntable. The in-position sensor trigger mounted on the rotating frame 4 triggers the in-position sensor to feedback signals to the PLC, which controls the motor to stop, thereby stopping the turntable.
