Description
Technical Field
[0001] The utility model relates to the technical field of centerless grinder manipulators, in particular to a centerless grinder manipulator device. Background Art
[0002] Centerless grinders are commonly used to grind shaft-type parts such as shafts, sleeves, and rings. Their working principle is that the workpiece does not contact the grinding tool during the grinding process, allowing the workpiece to rotate in the fixture while the grinding wheel grinds, thereby achieving high-precision and high-efficiency processing. They are suitable for processing external circles, internal holes, and workpieces of specific shapes.
[0003] In the prior art, such as the Chinese patent number CN201881211U, a centerless grinder manipulator device includes a pallet, a bracket fixed to a main machine frame, a hydraulic cylinder fixed to the lower part of the bracket, a pair of guide posts fixed to the upper part of the bracket, and a lifting seat driven by the piston rod of the hydraulic cylinder to slide along the pair of guide posts. The lifting seat is provided with a pair of mechanical arms for placing the workpiece on the pallet. The thickness of the lower part of the two mechanical arms is less than the diameter of the workpiece. An elastic pressure plate assembly is connected to the lifting seat and between the two mechanical arms. The device has a simple structure. The two ends of the workpiece are supported by a pair of mechanical arms for loading and unloading, and the hydraulic cylinder drives the mechanical arms. Therefore, loading and unloading are smooth and accurate, and the entire shaft can be profiled. The utility model solves the problem that the current centerless grinder cannot process a combined slender shaft composed of multiple concentric but unequal diameter cylinders. Compared with the previous segmented grinding using ordinary cylindrical grinding, the processing accuracy is improved and the scrap rate is reduced.
[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that the traditional centerless grinder robot device cannot better clamp the long shaft to be processed, which easily causes it to slip and needs to be replaced, which is very troublesome and reduces the overall work efficiency of the robot. After clamping, it is not convenient to quickly transport the polished long shaft to the collection pile, which reduces the practicality of the robot. Utility Model Content

A square plate 108 is fixedly connected to the bottom, and sliding grooves 111 are provided on both sides of the bottom of the square plate 108 near the edge. A long rack 112 is movably embedded inside the sliding groove 111, and one side of the long rack 112 is fixedly connected to an arc-shaped clamping plate 109. A motor 110 is fixedly installed inside the fixed block 107, and the output end of the motor 110 is fixedly connected to a circular gear 113. The outer surface of the circular gear 113 is engaged with one side of the outer surface of the two long racks 112. A plurality of threaded holes 101 are provided on the outer surface of the mounting plate 1.
[0033] In this embodiment, the mounting plate 1 is installed at the required position of the centerless grinder through multiple threaded holes 101 and bolts on the surface of the mounting plate 1. Then, after the grinding operation of the centerless grinder is completed, the staff turns on the external power supply of the electric telescopic rod 106 and uses the controller to start the electric telescopic rod 106. The output end of the electric telescopic rod 106 begins to push the square plate 108 to move vertically downward as a whole, and gradually moves to both sides of the long axis that has been ground. At this time, the outer surface of the long axis is located on the inner side of the two arc-shaped clamping plates 109. Then, the controller is used to start the motor 110. The output end of the motor 110 begins to drive the circular gear 113 to rotate continuously forward, and drives the two long racks 112 located in the two slide grooves 111 to move toward both sides of the long axis. As the two long racks 112 continue to move horizontally, the arc-shaped clamping plates 109 at the bottom of the long racks 112 gradually clamp the required long axis for processing firmly, thereby achieving better clamping of the required long axis for processing and preventing it from slipping. There is no need to reposition it, which is very simple and improves the overall working efficiency of the manipulator.

The outer surface of the circular gear 201 is meshed with one side of the long rack 2, and the top of the cylinder 202 is fixedly connected to the bottom center of the rotating column 104.
[0035] In this embodiment, when the long shaft needs to be transported quickly, the staff first uses the controller to make the electric telescopic rod 106 lift the long shaft vertically, then turns on the external power of motor 203, and uses the controller to start motor 203. The output end of motor 203 gradually drives the screw rod 205 to rotate forward, and uses the screw rod 205 to drive the long rack 2 to move horizontally. At this time, the limit column 204 limits the long rack 2 to prevent the long rack 2 from idling. While the long rack 2 moves, it drives the circular gear 201 to turn as a whole. The circular gear 201 drives the cylinder 202 and the rotating column 104 to turn as a whole. Then, when the long shaft rotates to the required position, the staff makes the electric telescopic rod 106 place the long shaft vertically in the pile of polished long shafts, so that after clamping is completed, it is convenient to quickly transport the polished long shaft to the collection pile, thereby improving the practicality of the manipulator.
[0036] Working principle: When in use, first install it in the required position of the centerless grinder through the multiple threaded holes 101 and bolts on the surface of the mounting plate 1. Then, after the grinding operation of the centerless grinder is completed, the staff turns on the external power supply of the electric telescopic rod 106, and uses the controller to start the electric telescopic rod 106. The output end of the electric telescopic rod 106 begins to push the square plate 108 to move vertically downward as a whole, and gradually moves to both sides of the grinded long axis. At this time, the outer surface of the long axis is located on the inner side of the two arc-shaped clamping plates 109. Then, the controller is used to start the motor 110, and the output end of the motor 110 begins to drive the circular gear 113 to rotate continuously forward, and drives the two long racks 112 located in the two slide grooves 111 to move toward both sides of the long axis. As the two long racks 112 continue to move horizontally, the arc-shaped clamping plate 109 at the bottom of the long rack 112 gradually clamps the required long axis for processing firmly, thereby achieving better clamping of the required long axis for processing and preventing it from slipping. , no need to reposition, it is very simple, which improves the overall working efficiency of the manipulator. When the long shaft needs to be transported quickly, the staff first uses the controller to make the electric telescopic rod 106 lift the long shaft vertically, then turn on the external power of motor 203, and use the controller to start motor 203. The output end of motor 203 gradually drives the screw rod 205 to rotate forward, and uses the screw rod 205 to drive the long rack 2 to move horizontally. At this time, the limit column 204 limits the long rack 2 to prevent the long rack 2 from idling. While the long rack 2 moves, it drives the circular gear 201 to turn as a whole. The circular gear 201 drives the cylinder 202 and the rotating column 104 to turn as a whole. Then, when the long shaft rotates to the required position, the staff makes the electric telescopic rod 106 place the long shaft vertically in the pile of long shafts that have been polished, so as to achieve the purpose of quickly transporting the polished long shaft to the collection pile after clamping is completed, thereby improving the practicality of the manipulator.
