Description

Technical Field

[0001] The utility model relates to the technical field of turntables, in particular to a heavy turntable device. Background Art

[0002] The existing turntables are generally the turntables of worm and gear conveyor lines and the turntables of gear conveyor lines. The turntable of the worm and gear conveyor line is connected to the motor by the worm, the worm drives the worm wheel to rotate, and the worm wheel drives the upper turntable to rotate. This transmission method has a large transmission ratio of the worm and worm wheel, and the turntable generally rotates slowly.

[0003] The existing gear conveyor line turntable is driven by a motor to rotate the gear, which drives the meshing rotating center gear to rotate, and drives the upper turntable to rotate. In this transmission mode, the rotating torque of the turntable depends on the output torque of the motor. When the load capacity is too large, a larger torque is required. The same motor requires a larger reduction ratio of the reducer, which will result in a slow turning speed of the turntable.

[0004] At the same time, the outer shell of the existing conveyor line turntable is mostly fastened with screws. When grease needs to be added to the interior or maintenance is required, the screws need to be loosened to remove the outer shell. After maintenance or maintenance, the screws need to be tightened again, which is very inconvenient;

[0005] In general, the existing conveyor line turntables generally have slow rotation speeds and low load-bearing capacity, which makes it difficult to meet the increasingly accelerated conveying production requirements.

[0090] The heavy-duty turntable device of the utility model is composed of a rotating component 1 and a conveying component 2. The rotating component 1 can complete a 90° rotation and turn the workpiece pallet 90°.

[0091] When rotating, the double-acting cylinder 114 is used as the power source, and there are two air ports for use with a neutral closed three-position five-way solenoid valve. When in the left position, the cylinder extends, and when in the right position, the cylinder retracts. The position of the piston of the double-acting cylinder 114 is detected by two magnetic switches 113, and the piston rod is connected to the rack mounting seat 117 through a joint 116. The side of the rack 107 is mounted on the rack mounting seat 117, and the bottom surface of the rack 107 is connected to the linear guide 106. The guide slider 108 is fixed on the slide mounting seat 115, and the slide mounting seat 115 is fixed on the rotating frame 119. The linear guide 106 drives the rack 107 to slide on the guide slider 108, guides the movement of the rack 107, and enhances the structural stability. 09 is an integrated component of a gear ring and a bearing, wherein the inner ring is a bearing and the outer ring is a gear ring. The bearing is fixed on a flange mounting seat 118, and the gear ring is connected to a rotating flange frame 216 of a conveying assembly. The rack 107 meshes with the outer gear ring of an outer gear 109 to convert the linear motion of the rack 107 into the rotational motion of the outer gear 109. Through two mutually perpendicular spring buffers 111, when the rotation limit is reached, the rotation limit block 201 of the conveying assembly contacts the spring buffer 111 to push the piston rod inward. The spring buffer 111 has a spring inside to buffer the stop. The buffering distance can be adjusted by adjusting the external hexagonal bolt 110. The buffering distance can be lengthened by turning it inward and shortened by turning it outward to achieve the best buffering effect. Two groups of vertical photoelectric switches 105 are installed on the upper surface of the rotating frame 119, which are used for workpiece entry detection and output detection respectively. The inspection door 103 can be opened by the door buckle 120 to facilitate the inspection and maintenance of internal parts. The foot 121 can fix the heavy turntable device on the ground. The upper surface of the turntable device can be adjusted to be flush with the external line body by adjusting the foot cup 101. When the turntable device needs to be moved, it can be moved conveniently by the casters 102;

[0092] During transportation, the workpiece can be transported into and out of the turntable device through the conveying assembly. The conveying assembly is installed on the outer gear ring of the slewing support 109 through the rotating flange frame 216, and operates synchronously with the outer gear ring to achieve a steering effect. When the rotation limit is reached, the rotation limit block 201 contacts the spring buffer 111 of the rotating assembly to stop the conveying assembly. The upper part of the friction line body is installed on the rotating frame 202. The friction line body is a line body conveyed by a chain and a roller. The motor 210 provides power. The bottom of the workpiece moves horizontally and linearly on the roller 207. The guide bar 203 guides the movement of the workpiece to ensure the linear movement of the workpiece. The non-return stopper 204 is a mechanical stopper, which does not require circuit control and has a reset spring inside. When the workpiece passes through the inclined surface of the stopper block of the non-return stopper 204, the block is pressed down by the weight of the workpiece and the workpiece can pass through. On the contrary, the workpiece cannot pass through the vertical surface of the stopper block of the non-return stopper 204, thereby achieving a one-way stop effect. The blocking cylinder 211 is a cylinder that moves up and down. When the stopper is stopped, the cylinder is inflated, the block of the blocking cylinder 211 is higher than the workpiece, and the workpiece is stopped; when the workpiece is released, the cylinder is de-aired, the spring resets and descends, the blocking cylinder 211 is lower than the workpiece, and the workpiece is released. The proximity switch 206 can detect whether the workpiece is in place, thereby controlling the blocking cylinder 211 to stop.

[0093] During operation, the workpiece is transported to the turntable from the straight conveyor line based on the outside. When the workpiece reaches the photoelectric switch 105, the photoelectric switch 105 gives an electrical signal to the controller, and the controller outputs the electrical signal to the motor driver. The motor driver drives the motor 210 to rotate, thereby driving the roller 207 to rotate, and the workpiece is transported to the turntable. When the workpiece reaches the proximity switch 206, the proximity switch 206 outputs an electrical signal to the controller, and the controller energizes the solenoid valve of the blocking cylinder 211. The solenoid valve is energized, and the air intake block of the blocking cylinder 211 is lifted, and the blocking cylinder 211 is higher than the workpiece, and the workpiece is stopped;

[0094] Subsequently, the controller energizes the solenoid valve of the double-acting cylinder 114, the solenoid valve changes direction, the double-acting cylinder 114 takes in air, the piston rod of the double-acting cylinder 114 extends, driving the rack 107 to move, the slewing support 109 to rotate, and the conveying assembly 2 above rotates synchronously. When the magnetic switch 113 detects the piston of the double-acting cylinder 114, the magnetic switch 113 outputs an electrical signal to the controller, the controller stops supplying power to the solenoid valve, the solenoid valve is de-energized, the piston rod of the double-acting cylinder 114 stops extending, the rotation limit block 201 is stopped by the spring buffer 111, and the conveying assembly 2 rotates 90° to be flush with another straight conveying line;

[0095] Finally, the controller stops supplying power to the electromagnetic valve of the blocking cylinder 211, the blocking cylinder 211 is reset by the spring, the block drops below the workpiece, and the workpiece can pass over the blocking cylinder 211. The controller outputs an electrical signal to the motor driver, the motor driver drives the motor 210 to operate, the roller group 207 operates, and the upper workpiece is output from the turntable.
