Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a grinding machine adjusting device. Background Art

[0002] A grinding machine is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive tools such as oilstones, abrasive belts, and free abrasives for processing. Examples include honing machines, superfinishing machines, belt grinders, lapping machines, and polishing machines.

[0003] Chinese patent CN220051122U discloses a surface grinder adjustment device, comprising a grinder body, a flat grinding mechanism, and a grinding seat, wherein the flat grinding mechanism and the grinding seat are fixedly mounted on the grinder body. In the utility model, a clamping block on a first fixing frame is inserted into a slot, so that the first fixing frame is engaged with a baffle, thereby fixing one end of a splash-proof cloth. At the same time, a protrusion is inserted into a socket, and a plug is inserted into the surface of the protrusion, so that the protrusion is engaged with a second fixing frame. During operation, the grinding seat reciprocates to perform grinding. After the position of the second fixing frame and the flat grinding mechanism is fixed, waste chips splashed during the grinding process will be blocked by the splash-proof cloth, preventing sparks generated during the grinding process from injuring workers, thereby protecting the personal safety of workers. By rotating the threaded bolt, the end of the threaded bolt is slidably engaged with the slide groove, making the deployment of the splash-proof cloth smoother during operation.

[0004] However, the above device is not convenient for adjusting the height of the grinder, and it is difficult to adjust the height of the grinder according to the size of different workpieces. In addition, the clamping effect of the above device on the workpiece is poor, which may cause the workpiece to move during processing, thereby affecting the grinding effect of the workpiece, and even the workpiece may be separated from the fixture, which is easy to cause safety hazards and has poor practicality. In addition, the grinding effect of the above device is poor, resulting in a low pass rate of the processed workpieces. Utility Model Content

[0028] In this solution, the lifting block 103 can drive the grinder 104 to move up and down, and the height of the grinder 104 can be adjusted according to the size of different workpieces. It is easy to use and has a wide range of applications. The grinding table 201 can move back and forth left and right on the workbench 1, thereby driving the workpiece to move left and right, repeatedly grinding the workpiece to improve the grinding effect of the workpiece. The four sets of tooth plates 302 can slide inside the mounting ring 301, thereby driving the clamping block 306 to clamp and fix the outside of the workpiece to prevent the workpiece from escaping from the clamping block 306. By clamping multiple surfaces of the workpiece, the workpiece can be fixed above the grinding table 201, which is convenient for the grinding operation of the workpiece.

[0029] Please refer to Figure 2 As shown, the grinding mechanism 2 also includes a grinding motor 203, which is fixedly installed at the lower end of the workbench 1. The output end of the grinding motor 203 extends to the upper end of the workbench 1 and is fixedly connected to a crank 204. The end of the crank 204 away from the grinding motor 203 is fixedly connected to a crank rod 205. The lower end of the grinding table 201 is fixedly connected to a drive ring 206, and the crank rod 205 is slidably connected to the inside of the drive ring 206.

[0030] Two sets of guide rails 101 are fixedly mounted on the upper end of the workbench 1 , and a guide block 202 slidably connected to the guide rails 101 is fixedly connected to the lower end of the grinding table 201 .

[0031] In this solution, the grinding motor 203 is electrically connected to an external power supply. The grinding motor 203 can drive the crank 204 to make the crank rod 205 perform circular motion, so that the crank rod 205 slides inside the drive ring 206 and drives the drive ring 206 to move back and forth left and right, thereby driving the grinding table 201 to move back and forth on the guide rail 101, and then driving the workpiece to move back and forth under the grinder 104, so that the upper surface of the workpiece contacts the grinder 104, thereby performing a grinding operation on it, and repeatedly grinding the upper surface of the workpiece through the reciprocating movement of the workpiece, thereby increasing the grinding effect of the grinder 104 on the workpiece and improving the quality of the workpiece.

[0032] Please refer to Figure 3-4 As shown, the interior of the mounting ring 301 is rotatably connected to a gear 305 meshing with the tooth plate 302 through a bearing, and a clamping motor 308 is fixedly installed at the lower end of the mounting ring 301. The output end of the clamping motor 308 extends to the inner side of the mounting ring 301 and is fixedly connected to one set of gears 305. The inner side of the mounting ring 301 is rotatably connected to a gear ring 307, which meshes with the gear 305.

[0033] At least four groups of guide grooves 303 are provided inside the mounting ring 301 . A guide rod 304 is fixedly connected to the outer side of the tooth plate 302 . The guide rod 304 is slidably connected to the guide groove 303 .

[0034] In this solution, the clamping motor 308 is electrically connected to the external power supply. The clamping motor 308 can drive one of the groups of gears 305 to rotate, and then drive the other three groups of gears 305 to rotate simultaneously through the gear ring 307, and then drive the tooth plate 302 to slide inside the mounting ring 301, so that the clamping block 306 clamps the workpiece, which is convenient for fixing the workpiece. Reversing the clamping motor 308 can release the fixation of the workpiece by the clamping block 306, which is convenient for removing the workpiece. Through the guide rod 304 and the guide groove 303, the tooth plate 302 can slide stably inside the mounting ring 301, thereby improving the clamping effect of the clamping block 306 on the workpiece.

[0035] Please refer to Figure 5 As shown, the interior of the mounting frame 102 is fixedly connected to a limit rod 105, the lifting block 103 is slidably connected to the outside of the limit rod 105, the interior of the mounting frame 102 is rotatably connected to a screw 106 through a bearing, the screw 106 is threadedly connected to the lifting block 103, and the screw 106 extends to the upper end of the mounting frame 102 and is fixedly connected to an adjustment handle 107.

[0036] In this solution, the screw 106 can be driven to rotate by adjusting the handle 107, thereby driving the lifting block 103 to move up and down, so that the height of the grinder 104 can be adjusted according to the size of the workpiece. The lifting block 103 can be stably moved by the limit rod 105 to prevent the lifting block 103 from rotating.

[0037] The working principle and usage process of the present invention are as follows: First, the screw rod 106 is driven by the adjusting handle 107 to move the lifting block 103, and the height of the grinder 104 is adjusted according to the size of the workpiece. At this time, the workpiece is placed in the middle of the mounting ring 301, and the clamping motor 308 is started to drive one set of gears 305 to rotate, and then the other three sets of gears 305 are driven to rotate at the same time through the gear ring 307, so that the four sets of tooth plates 302 slide simultaneously inside the mounting ring 301, thereby driving the clamping block 306 to clamp the workpiece on all sides. Afterwards, the grinding motor 203 is started, and the crank rod 205 is driven by the crank 204 to make the drive ring 206 move back and forth, thereby driving the grinding table 201 to move back and forth, so that the surface of the workpiece is repeatedly ground by the grinder 104, thereby increasing the grinding effect of the workpiece.
