Description

Technical Field

[0001] The invention relates to the technical field of flange grinding, in particular to a grinding device for flange processing. Background Art

[0002] The grinding process in flange processing is a crucial link, which is directly related to the quality of the flange finished product. The main purpose of grinding is to remove surface defects such as burrs, oxide scale, rust, etc., and improve surface quality and surface finish.

[0003] Traditional flange grinding methods mainly include manual grinding and mechanical grinding. Manual grinding is suitable for flanges with small batches, complex shapes or high precision requirements. When grinding, workers usually use tools such as sandpaper and grinding wheels. Mechanical grinding is suitable for flanges with large batches and regular shapes. Electric grinders, belt sanders and other equipment are usually used to achieve efficient and uniform grinding through automation or semi-automation.

[0004] At present, magnetic grinders are also used in the market to grind and polish the flange surface. Magnetic grinders are also called magnetic polishers, also known as magnetic grinding machines. The working principle of magnetic grinders is mainly based on the power of magnetic field. An electromagnetic coil is installed inside. When the electromagnetic coil is energized, a strong magnetic field will be generated. After the magnetic field is generated, the magnetic polisher will transfer the magnetic force to the magnetic abrasive through the magnetic field. These magnetic abrasives are usually a mixture of magnetic particles, which can be adsorbed on the surface of the workpiece for polishing. Under the action of magnetic force, the magnetic abrasive will rotate and grind at high speed on the surface of the workpiece. This movement can cover every corner of the workpiece surface, including complex parts such as planes, grooves and inner holes. Strong friction and impact force will be generated between the abrasive and the workpiece surface, thereby accurately removing tiny bumps, knife marks and burrs on the workpiece surface, making the workpiece surface smooth, thereby grinding the workpiece.

[0005] At present, the existing magnetic grinder usually puts the flange directly into the grinding liquid mixed with abrasives, and the abrasives rotate at high speed to generate strong friction and impact force with the flange surface, thereby grinding the flange. However, the flange and the abrasive are directly mixed together, which makes it inconvenient to remove the flange from the grinding liquid, which easily affects the grinding efficiency; therefore, it does not meet the existing needs. In this regard, we propose a grinding equipment for flange processing. Summary of the invention

The two baffles 127 are both rotatably arranged on the inner wall of the grinder body 1, and the two baffles 127 can only be rotated upward. When the flange body is pressed down on the baffle 127, the flange body is exposed from the discharge port 123, and the circular hole opened in the middle of the flange body is completely exposed above the discharge port 123.

Not only that, the conveyor belt 140 is guided by the conveyor rollers 130 at different heights, so that the conveyor belt 140 first drives the hook 160 to insert into the flange body, and lifts the flange body upward from the discharge port 123, so that the flange body is suspended on the hook 160, and then drives the flange body to descend into the grinding pool 100, and immerses it in the grinding liquid, and grinds the flange body through the grinder body 1. Finally, the flange body is lifted out of the grinding pool 100, so as to quickly and effectively remove the flange body from the grinding liquid, thereby improving the grinding efficiency of the flange body, and solving the existing magnetic grinder as much as possible. Usually, the flange is directly placed in the grinding liquid mixed with abrasives, and the abrasives rotate at high speed to generate strong friction and impact force with the flange surface, thereby grinding the flange. However, the flange and the abrasive are directly mixed together, which is not convenient for removing the flange from the grinding liquid, which easily affects the grinding efficiency.

[0036] Embodiment 2: This embodiment is intended to solve the problem that it is inconvenient to timely control the opening and closing of the drain hole 170, and it is difficult to timely discharge and replace the grinding waste liquid used for a long time, which easily affects the grinding effect.

A second tooth 214 is fixedly installed on the side of the circular plate 213. A second gear 215 is rotatably arranged in the side wall of the grinder body 1. The second tooth 214 is intermittently meshed with the second gear 215.

[0037] The blocking plate 190 is slidably arranged in the side wall of the grinder body 1, and a latch 220 is also slidably arranged on the inner side of the grinder body 1. The latch 220 is arranged in an "L" shape. A socket 221 for use with the latch 220 is opened on the side of the blocking plate 190. The end of the latch 220 is inserted in the socket 221. A first spring 222 is sleeved on the outer side of the latch 220. One end of the first spring 222 is fixedly connected to the inner wall of the grinder body 1, and the other end of the first spring 222 is fixedly connected to the outer side of the latch 220. A lever 223 is fixedly installed on the lower side of the second gear 215 near the edge, and the lever 223 intermittently conflicts with the latch 220.

[0038] A through hole 230 is opened on the side of the blocking plate 190, and the through hole 230 is located at the lower side of the drainage hole 170.

[0039] In this embodiment: the first motor 150 drives the conveyor belt 140 to transport the flange body to the grinding pool 100 for grinding. At the same time, the first motor 150 drives the conical block 210 and the first teeth 211 thereon to rotate through the first shaft 151, so that the first teeth 211 rotates one circle to shift the conical gear 212, and the conical gear 212 drives the circular plate 213 and the second teeth 214 thereon to rotate through the second shaft 200. Similarly, the second teeth 214 rotates one circle to shift the second gear 215. Finally, the second gear 215 drives the lever to rotate and pushes the latch 220, so that the latch 220 is pulled out of the socket 221, the limiting effect on the blocking plate 190 is released, and the first spring 222 is compressed; Subsequently, under the action of the rebound force of the second spring 231, the sealing plate 190 is pushed upward, so that the through hole 230 overlaps and is connected with the drainage hole 170, so that the drainage hole 170 is opened to discharge the grinding waste liquid, which is convenient for timely controlling the opening and closing of the drainage hole 170, and timely discharging and replacing the grinding waste liquid that has been used for a long time, thereby improving the grinding effect.

[0040] It should be noted that after the waste liquid is discharged, the connecting rod 232 is pressed down to drive the blocking plate to move down and reset, and under the action of the rebound force of the first spring 222, the pin 220 is driven to be reinserted into the socket 221, thereby closing the drainage hole 170 again.

[0041] Embodiment 3: This embodiment is intended to further promote the solution of the problem that when the flange body is being polished in the polishing pool 100, due to the impact of the steel needle abrasive, the flange body is easily separated from the hook 160 and falls into the polishing liquid, making it inconvenient to remove the flange body from the polishing liquid. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 The hook 160 is set to be "U"-shaped, the length of the left side of the hook 160 is greater than the length of the right side of the hook 160, and the right side of the hook 160 is set to be an arc-shaped rod, the left side of the hook 160 is fixedly connected to the lower side of the conveyor belt 140, a protrusion 240 is slidably inserted in the middle of the hook 160, and an extension rod 241 is slidably inserted in the right side of the hook 160.

[0043] In this embodiment: when the flange body is suspended on the hook 160, the flange body's own gravity presses the protrusion 240 downward, and the protrusion 240 presses the left side of the lever 244 downward, thereby pushing the extension rod 241 on the right side of the lever 244 upward. Moreover, the support rod 243 is located on the left side of the lever 244 close to the protrusion 240, so that the rising distance of the extension rod 241 is greater than the descending distance of the protrusion 240, so that the distance between the upper end of the extension rod 241 and the left side of the hook 160 is smaller than the thickness of the flange body, so that the extension rod 241 surrounds the side of the flange body, making it difficult for the flange body to detach from the hook 160 and fall into the polishing liquid, thereby facilitating the removal of the flange body from the polishing liquid.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
