Description

Technical Field

[0001] This utility model relates to the field of removing burrs or polishing the surface of long plates in machining, and to an automatic flipping device for long plates used on deburring machines and polishing machines, and more particularly to an automatic flipping device for grinding long plates. Background Technology

[0002] In the field of machining, after long plate workpieces are processed by stamping, milling and other processes, irregular burrs and metal debris are often left on their edges and surfaces. At this time, the surface needs to be polished. Since most polishing equipment on the market can only deburr or polish one side of the workpiece, it cannot meet the function of automatic flipping for long plate workpieces that need to be polished on both sides. In this case, manual polishing is time-consuming and labor-intensive.

[0003] Long plate workpieces have a significant length-to-width ratio, and there are technical bottlenecks in their grinding process. Commercially available flipping devices (such as CNC flipping machines and robotic arm clamping systems) have significant defects in the application of long plate workpieces. For example, the failure of clamping deformation control leads to poor flatness after grinding, and metal dust that is not removed in time during the flipping process is re-adsorbed onto the workpiece surface due to inertia, resulting in an increased contamination rate of the ground surface.

[0004] Therefore, considering the characteristics of long plate workpieces, we plan to adopt an automatic flipping device for grinding long plate workpieces. Through debugging, it can adapt to long plate workpieces of different lengths and thicknesses, and achieve smooth and fast automatic flipping, thereby maximizing work efficiency. Utility Model Content

[0005] Purpose of the invention: In view of the shortcomings of the existing technology, the applicant has designed an automatic flipping device for grinding long plate parts after multiple practical improvements. This device enables long plate workpieces to be flipped over smoothly and quickly after one side has been ground, so that the other side can be ground smoothly with the other side facing up.

[0006] To address the deficiencies in existing technologies, the technical solution adopted by this utility model to solve the aforementioned technical problems is as follows: including...

[0007] Connecting seats are located on both sides of the conveyor belt to connect the two conveyor belts with a relative height difference and to install a flipping component;

[0008] The gap compensator connects to the connecting seat and fixes the two shaft ends of the pressure roller;

[0009] The pressure roller is connected to the gap compensator and is in contact with the surface of the first conveyor belt;

[0010] A flip-up baffle is slidably connected to a connecting seat and a vacuum tube is installed therein;

[0011] Vacuum tube, equipped with a vacuum generator and a vacuum pump.

[0012] Based on the above technical solution, a further preferred solution of this utility model is: the cylindrical end of the gap compensator is threadedly connected to the connecting seat, a spring is installed on the cylindrical end, and the ring of the gap compensator is fitted into the end of the pressure roller shaft.

[0013] Based on the above technical solution, a further preferred solution of this utility model is: both shaft ends of the pressure roller are fitted into the ring of the gap compensator and fastened with screws, and the surface of the pressure roller is in contact with the surface of the first conveyor belt.

[0014] Based on the above technical solution, a further preferred solution of this utility model is: the flipping baffle is concave in shape, the two bent edges are placed on the connecting seat and a sliding groove is provided, the flipping baffle is slidably connected to the connecting seat, and a vacuum tube is fixed at the bottom of the flipping baffle.

[0015] Based on the above technical solution, a further preferred solution of this utility model is: the vacuum tube is a hexagonal tube, with multiple air intake holes arranged in an array on one side, and the vacuum tube is equipped with a vacuum generator and a vacuum pump.

[0016] Compared with the prior art, the advantages of this invention are: it makes full use of the characteristics of long plate workpieces and uses the center of gravity to achieve the purpose of quick flipping. Compared with most flipping mechanisms that use motors, it has a simple structure, completes the work at low cost, has high work efficiency, and saves a lot of manpower. During the flipping process, the long plate workpiece can shake off some of the metal dust, reducing the contamination rate of the subsequent polishing surface. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, an automatic reverse-side grinding device for long plates includes a connecting seat 1, which is set on both sides of a conveyor belt to connect the two conveyor belts with a relative height difference and to set a flipping assembly; a gap compensator 2, which is connected to the connecting seat 1 and fixes the two shaft ends of a pressure roller 3; a pressure roller 3, which is connected to the gap compensator 2 and is in contact with the surface of the first conveyor belt 6; a flipping baffle 4, which is slidably connected to the connecting seat 1 and to set a vacuum tube 5; and a vacuum tube 5, which is equipped with a vacuum generator and a vacuum pump.

[0025] Furthermore, the cylindrical end 21 of the gap compensator 2 is threadedly connected to the connecting seat 1. A spring 8 is installed on the cylindrical end 21. The spring 8 is always in a compressed state. It can clamp and transport long plates of different thicknesses to the pressing roller 3. The ring 22 of the gap compensator 2 is fitted into the shaft end of the pressing roller 3.

[0026] Furthermore, both ends of the pressure roller 3 are fitted into the ring 22 of the gap compensator 2 and fastened with screws for axial positioning, so that the surface of the pressure roller 3 is in contact with the surface of the first conveyor belt 6.

[0027] Furthermore, the flipping baffle 4 is concave in shape, with the two bent edges 41 placed on the connecting seat 1 and a sliding groove 42 provided. The flipping baffle 4 is slidably connected to the connecting seat 1, so that the flipping baffle 4 can be adjusted back and forth. The purpose is to facilitate debugging. For long plates of different lengths, the offset of the center of gravity of the long plate is controlled by sliding adjustment. A vacuum tube 5 is fixed at the bottom of the flipping baffle 4.

[0028] Furthermore, the vacuum tube 5 is a hexagonal tube with multiple suction holes 51 arranged in an array on one side. The vacuum tube is equipped with a vacuum generator and a vacuum pump. When the long plate leans against the flipping baffle 4, the vacuum tube 5 first sucks the long plate to prevent it from falling down along the edge of the flipping baffle 4 and ultimately causing the flipping to fail.

[0029] The practical process of this utility model is as follows: The long plate is conveyed to the pressing roller 3 by the first conveyor belt 6. The pressing roller 3 and the first conveyor belt 6 clamp the long plate and convey it forward to the top of the flipping baffle 4. Due to the shift of the center of gravity, one end of the long plate falls on the second conveyor belt 7. At this time, the long plate leans against the edge of the flipping baffle 4. The vacuum tube 5 sucks the surface of the long plate. At the same time, the second conveyor belt 7 conveys it forward, and the long plate is automatically flipped.
