Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and in particular to an automatic material handling device for a precision surface grinder. Background Technology

[0002] In the existing technology, in the field of machining, precision surface grinders are important processing equipment and are widely used in the surface grinding of various high-precision workpieces. However, traditional workpiece conveying methods often have many problems, such as the workpiece being easily damaged by bumps or collisions during the conveying process, and the inability to effectively protect the workpiece, which makes the workpiece still easily damaged during the conveying process, affecting the processing quality and the surface finish of the workpiece.

[0003] A search revealed a Chinese patent application with patent number 202121112053.4, which discloses an automated material handling device for a surface grinder. The device includes a fixed frame, a controller fixedly connected to the left side of the fixed frame, a material handling frame located at the top inner side of the fixed frame, a motor fixedly connected to the right rear end of the fixed frame, and the motor's spindle passing through the fixed frame. The motor's spindle is rotatably connected to the fixed frame, and a gear is fixedly connected to the end of the motor's spindle. A rack is meshed with the outer side of the gear, and the rack is fixedly connected to the material handling frame.

[0004] The aforementioned patent has the following shortcomings in an automated material handling device for a surface grinder: during the material handling process, the workpiece is ultimately squeezed out of the support sleeve for feeding. After being squeezed out, the workpiece falls into the workpiece positioning mechanism inside the surface grinder under its own gravity. Due to the lack of protective measures for the workpiece, it is easy for the workpiece to be bumped and damaged after falling. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic material feeding device for a precision surface grinder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic material handling device for a precision surface grinder includes a mounting table and a conveying section on top of it. A vertical plate is fixedly mounted on the mounting table, and an electric telescopic rod is provided on the side of the vertical plate. The output end of the electric telescopic rod is connected to a housing frame, and a roller is rotatably mounted inside the housing frame. A frame plate is provided on the side of the conveying section, and an elastic element is connected to the frame plate through an intermediate plate. An inclined plate that cooperates with the roller is installed at the bottom of the elastic element, and a lifting seat is connected to the bottom of the inclined plate through a connecting plate.

[0028] Example 1

[0029] An automatic material handling device for a precision surface grinder, designed to protect the workpiece, such as... Figures 1 to 5As shown, the system includes a mounting platform 1, a conveying unit mounted on the top of the mounting platform 1, a vertical plate 8 fixed to the outer wall of the top of the mounting platform 1 by bolts, an electric telescopic rod 2 fixed to one side of the outer wall of the vertical plate 8 by bolts, a receiving frame 19 fixed to the output end of the electric telescopic rod 2 by pins, a roller 18 rotatably connected to the inner wall of the receiving frame 19, a frame plate 17 fixed to the side wall of the conveying unit, an intermediate plate 24 welded to one side of the outer wall of the frame plate 17, an elastic element mounted on the top of the intermediate plate 24, an inclined plate 13 fixed on the elastic element for use with the roller 18, and a lifting seat 20 welded to the bottom of the inclined plate 13 through a connecting plate 7.

[0030] The conveyor unit can be used to transport the workpiece. When the workpiece is transported to the position directly opposite the push plate 9, the electric telescopic rod 2 can drive the push plate 9 to move laterally. During the movement, the push plate 9 pushes the workpiece on the conveyor unit. After being pushed, the workpiece moves to the lifting seat 20. The top of the lifting seat 20 is provided with an inclined surface, so that the workpiece slides along the inclined surface until it is in contact with the inner wall of the frame plate 17. As the output end of the electric telescopic rod 2 continues to move, when the roller 18 moves to be in contact with the side of the inclined plate 13, the roller 18 squeezes the side of the inclined plate 13. The side of the inclined plate 13 is also an inclined surface. During the process of the roller 18 squeezing the inclined surface, the inclined surface is used to convert the lateral movement of the roller 18 into the vertical movement of the inclined plate 13. During the downward movement of the inclined plate 13, the elastic element generates elastic deformation. The connecting plate 7 drives the lifting seat 20 to move downward along the inner wall of the frame plate 17, thereby moving the workpiece on the lifting seat 20 downward. When the workpiece and the frame plate 17 are misaligned, the workpiece slides down along the top inclined surface of the lifting seat 20 to achieve the initial unloading.

[0031] By setting the lifting seat 20 to be able to move up and down, the workpiece can be protected during the material transportation process, preventing it from falling directly from the conveyor and causing collisions, and also preventing the workpiece from rolling over.

[0032] The conveying unit includes a first side plate 3 and a second side plate 5. Both the first side plate 3 and the second side plate 5 are fixed to the top outer wall of the mounting platform 1 by bolts. A roller 16 is rotatably connected between the first side plate 3 and the second side plate 5. A conveyor belt 12 is driven between the two rollers 16. A drive motor 4 is fixed to one side outer wall of the first side plate 3 by bolts. The output end of the drive motor 4 is connected to one end of one of the rollers 16 through a coupling.

[0033] The drive motor 4 can drive the roller 16 to rotate, thereby causing the conveyor belt 12 to move under the transmission of the roller 16. When it is necessary to transport the workpiece, the workpiece is placed on the conveyor belt 12 and the conveyor belt 12 is used to transport the workpiece.

[0034] The elastic element includes a housing 21 and a T-shaped rod 23. The housing 21 is fixed to the top outer wall of the intermediate plate 24 by screws, and the T-shaped rod 23 is slidably connected to the inner wall of the through hole at the bottom of the housing 21. A spring 22 is engaged between the top of the T-shaped rod 23 and the top inner wall of the housing 21, and the inclined plate 13 and the bottom of the T-shaped rod 23 are fixedly connected.

[0035] The housing 21 and T-shaped rod 23 can guide the movement path of the inclined plate 13, thereby ensuring that the inclined plate 13 moves in the vertical direction. The elastic force of the spring 22 allows the lifting seat 20 to quickly reset after the roller 18 and the inclined plate 13 disengage.

[0036] A rotary conveying assembly is installed on one side of the outer wall of the mounting platform 1. The rotary conveying assembly includes a rotary motor 14 and an extension plate 15. The extension plate 15 is welded to one side of the outer wall of the mounting platform 1, and the rotary motor 14 is fixed to the bottom outer wall of the extension plate 15 by bolts. The output end of the rotary motor 14 is connected to a rotating plate 10 through a coupling, and both ends of the rotating plate 10 are welded with shift forks 11. The top outer wall of the extension plate 15 is fixed with a placement plate 6 by screws.

[0037] After the workpiece slides off the lifting seat 20, it can be received by the placement plate 6. During the rotation of the rotating plate 10 and the shift fork 11 driven by the rotary motor 14, the shift fork 11 moves the workpiece by rotation. The shift fork 11 has a U-shaped bending structure and an arc transition part at its end. In the actual processing, the precision surface grinder can be placed next to the placement plate 6. The shift fork 11 moves the workpiece, thereby moving the workpiece to a position close to the precision surface grinder for feeding.

[0038] Working principle: The workpiece is first placed on the conveyor belt 12 driven by the drive motor 4. The conveyor belt 12 moves, transporting the workpiece from the input end to the position directly opposite the push plate 9. When the workpiece reaches the designated position, the electric telescopic rod 2 is activated to push the push plate 9 to move laterally. The pushing action of the push plate 9 causes the workpiece to move along the conveyor belt 12 until the workpiece contacts the lifting seat 20. The top of the lifting seat 20 is designed with an inclined surface, allowing the workpiece to slide smoothly along the inclined surface to the position where it fits against the inner wall of the frame plate 17, ensuring accurate positioning of the workpiece in the horizontal direction. As the electric telescopic rod 2 continues to move, the rollers 18 in the receiving frame 19 gradually come into contact with the side of the inclined plate 13. Since the side of the inclined plate 13 is also designed with an inclined surface, the lateral movement of the rollers 18 is converted into the lateral movement of the inclined plate 13. During the vertical movement, as the inclined plate 13 moves downward, elastic deformation occurs through the elastic element, which in turn drives the lifting seat 20 to move downward along the inner wall of the frame plate 17. During this process, the workpiece descends together with the lifting seat 20. When misalignment occurs between the workpiece and the frame plate 17, the workpiece slides down the inclined surface at the top of the lifting seat 20 to achieve initial unloading. After sliding down, the workpiece lands on the placement plate 6. The rotary motor 14 starts, driving the rotating plate 10 and the shift fork 11 to rotate. The shift fork 11 rotates the workpiece, causing it to rotate around the center of the placement plate 6. In actual processing, the precision surface grinder can be placed next to the placement plate 6. The shift fork 11 is used to move the workpiece, thereby moving the workpiece to a position close to the precision surface grinder for feeding.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
