Description

Technical Field

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

[0002] Grinding fixtures are auxiliary tools used to ensure accurate workpiece positioning, stable fixation, and consistent grinding quality during grinding. The selection and use of grinding fixtures are crucial to ensuring grinding quality and improving production efficiency. Correctly selecting and using fixtures can significantly improve the accuracy and consistency of grinding processes.

[0003] According to a publicly disclosed grinding fixture for a support part of a grinder (Announcement No.: CN220445948U), in the above application, since the inner diameter of the workpiece is relatively small, it is necessary to lock the workpiece by tightening the bolts located on the inner side of the workpiece, which is very inconvenient. In actual work, when encountering some workpieces with smaller inner diameters, the bolts on the inner side cannot even be tightened, and the workpiece of the grinder cannot be supported. Utility Model Content

[0004] The purpose of the present utility model is to provide a grinding tool for a grinding machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a grinding tool for a grinding machine, comprising a grinding machine, a base, a cylinder and a grinder, wherein a control unit capable of fixing workpieces of different inner diameters is provided above the grinding machine;

[0006] Among them, the control part includes bracket 1, motor, rotating shaft, rotating ring, rotating rod, toggle rod, bracket 2, rotating column, transmission block, toggle groove, screw, sealing plate, slide plate, hinge block, hinge rod, support rod, connecting block, and tightening block. The bottom surface of the base is fixedly connected to the top surface of the grinder, the surface of the base is fixedly connected to the cylinder, and the output shaft of the cylinder is fixedly connected to the grinder.

[0007] Preferably, the top surface of the grinder is fixedly connected to a bracket 1, the surface of the bracket 1 is fixedly connected to a motor, the inner side of the bracket 1 passes through and is rotatably connected to a rotating shaft, and the output shaft of the motor passes through the rotating shaft and is fixedly connected.

[0008] Preferably, the rotating shaft passes through and is fixedly connected to a rotating ring and a rotating rod, and one end of the rotating rod away from the rotating shaft passes through and is fixedly connected to a shifting rod.

[0009] Preferably, the top surface of the grinder is fixedly connected to a bracket 2, and a rotating column is passed through and rotatably connected to the inner side of the bracket 2. The output shaft of the motor will drive the rotating ring and the rotating rod to rotate together through the rotating shaft, and the rotating rod will drive the shift rod to shift the transmission block a certain distance only after rotating one circle. By continuously rotating the shift rod, the shift rod can achieve the same rotation stroke of the transmission block each time it shifts.

[0010] Preferably, the rotating column passes through and is fixedly connected to a transmission block, a toggle groove is provided on the surface of the transmission block, and the toggle rod is inserted into the toggle groove.

[0011] Preferably, a screw is passed through and threadedly connected to the inner side of the rotating column, a sealing plate is fixedly connected to the surface of the rotating column, and one end of the screw located on the inner side of the rotating column is passed through and rotatably connected to a slide plate, and the sheet workpiece is aligned with the left side of the rotating column and pushed in, so that the rotating column is inserted into the inner diameter of the sheet workpiece, and then the screw is twisted to gradually move away from the rotating column, but because the support rod is limited by the inner wall of the rotating column, the screw will pull the slide plate to slide in the rotating column when it rotates and moves away from the sealing plate, and the slide plate passes through the rotating column and is slidably connected.

[0012] Preferably, the surface of the slide is penetrated by and fixedly connected with a hinge block, and the inner side of the hinge block is penetrated by and hinged with a hinge rod. When the slide gradually slides toward the inside of the rotating column, the hinge block will apply pressure to the support rod through the hinge rod, and when the support rod is resisted by the inner wall of the rotating column, it will force the two ends of the hinge rod to rotate. The end of the hinge rod away from the hinge block is penetrated by and hinged with a support rod, and the end of the support rod away from the hinge rod is fixedly connected with a connecting block, and the end of the connecting block away from the support rod is fixedly connected with a tightening block. As the distance between the slide and the inner wall of the rotating column gradually shortens, the rotation of the hinge rod will gradually push the support rod to open, so that the support rod will open the tightening block through the connecting block, thereby tightening the inner diameter of the sheet-like workpiece.

[0013] Compared with the prior art, the present invention provides a grinding tool for a grinding machine, which has the following beneficial effects:

[0014] 1. The grinding tool used in the grinder has a grinding process in which when the slide plate gradually slides toward the inside of the rotating column, the hinge block applies pressure to the support rod through the hinge rod. When the support rod is resisted by the inner wall of the rotating column, the two ends of the hinge rod are forced to rotate. As the distance between the slide plate and the inner wall of the rotating column gradually shortens, the rotation of the hinge rod will gradually push the support rod to open, so that the support rod opens the tightening block through the connecting block, thereby tightening the inner diameter of the sheet-like workpiece, avoiding the small internal space making it difficult to tighten the bolts. At the same time, the tightening blocks arranged in a circular array can expand proportionally to tighten the inner diameter of the sheet-like workpiece, avoiding the deviation of the workpiece caused by tightening the bolts separately.

[0015] 2. The grinder uses a grinding fixture. When the motor is started, the output shaft of the motor will drive the rotating ring and the rotating rod to rotate together through the rotating shaft. The rotating rod will drive the lever to move the transmission block a certain distance after rotating one circle. By continuously rotating the lever, the lever can achieve the same rotation stroke each time the lever moves the transmission block, thereby achieving the effect of fixed-distance rotation to ensure that the spacing of the workpiece grinding holes is the same, avoiding large errors that affect the position offset of the ground workpiece holes.

[0021] like Figures 1-4 As shown, the utility model provides a technical solution: a grinding tool for a grinding machine, comprising a grinding machine 1, a base 3, a cylinder 4 and a grinder 5. A control unit 2 capable of fixing workpieces of different inner diameters is provided above the grinding machine 1;

[0022] The control unit 2 includes a bracket 1 21, a motor 22, a rotating shaft 23, a rotating ring 24, a rotating rod 25, a shifting lever 26, a bracket 27, a rotating column 28, a transmission block 29, a shifting slot 210, a screw 211, a sealing plate 212, a slide plate 213, a hinge block 214, a hinge rod 215, a support rod 216, a connecting block 217, and a tightening block 218. The bottom surface of the base 3 is fixedly connected to the top surface of the grinder 1. The surface of the base 3 is fixedly connected to the cylinder 4, and the output shaft of the cylinder 4 is fixedly connected to the grinder 5. The top surface of the grinder 1 is fixedly connected to the bracket 1 21, and the surface of the bracket 1 21 is fixedly connected to the motor 22. The rotating shaft 23 extends through the inner side of the bracket 1 21 and is rotatably connected. The output shaft of the motor 22 extends through the rotating shaft 23 and is fixedly connected. The rotating ring 24 and the rotating rod 25 extend through the rotating shaft 23 and are fixedly connected. The end of the rotating rod 25 away from the rotating shaft 23 extends through and is fixedly connected to the shifting lever 26. The top surface of the grinding machine 1 is fixedly connected to a bracket 27. A rotating column 28 extends through the inner side of the bracket 27 and is rotatably connected thereto. When the motor 22 is started, the output shaft of the motor 22 drives the rotating ring 24 and the rotating rod 25 to rotate together via the rotating shaft 23. Only after the rotating rod 25 rotates one circle will it drive the shift lever 26 to shift the transmission block 29 a certain distance. By continuously rotating the shift lever 26, the shift lever 26 rotates the transmission block 29 a certain distance each time, achieving a fixed-distance rotation effect to ensure that the spacing of the holes ground on the workpiece is consistent. The rotating column 28 extends through and is fixedly connected to the transmission block 29. The surface of the transmission block 29 is provided with a shifting groove 210, into which the shift lever 26 is inserted. The inner side of the rotating column 28 is penetrated by a screw rod 211 and is threadedly connected. The surface of the rotating column 28 is fixedly connected to a closing plate 212. One end of the screw rod 211 located on the inner side of the rotating column 28 is penetrated by a slide plate 213 and is rotatably connected. The sheet workpiece is aligned with the left side of the rotating column 28 and pushed in so that the rotating column 28 is inserted into the inner diameter of the sheet workpiece. Then the screw rod 211 is twisted so that the screw rod 211 gradually moves away from the rotating column 28. However, because the support rod 216 is limited by the inner wall of the rotating column 28, the screw 211 will pull the slide plate 213 to slide in the rotating column 28 when it rotates and moves away from the closing plate 212. The slide plate 213 penetrates the rotating column 28 and is slidably connected.The surface of the slide plate 213 is penetrated and fixedly connected with a hinge block 214, and the inner side of the hinge block 214 is penetrated and hinged with a hinge rod 215. When the slide plate 213 gradually slides toward the inside of the rotating column 28, the hinge block 214 will apply pressure to the support rod 216 through the hinge rod 215. When the support rod 216 is resisted by the inner wall of the rotating column 28, it will force the two ends of the hinge rod 215 to rotate. The end of the hinge rod 215 away from the hinge block 214 penetrates and hinges. It is connected to a support rod 216, and the end of the support rod 216 away from the hinged rod 215 is fixedly connected to a connecting block 217, and the end of the connecting block 217 away from the support rod 216 is fixedly connected to a tightening block 218. As the distance between the slide 213 and the inner wall of the rotating column 28 gradually shortens, the rotation of the hinged rod 215 will gradually push the support rod 216 to expand, so that the support rod 216 will expand the tightening block 218 through the connecting block 217, thereby tightening the inner diameter of the sheet-like workpiece.

[0023] Based on the above embodiment, when the grinding tool is grinding the hole of the sheet workpiece, the sheet workpiece can be first aligned with the left side of the rotating column 28 and pushed in, so that the rotating column 28 is inserted into the inner diameter of the sheet workpiece, and then the screw 211 is twisted to gradually move the screw 211 away from the rotating column 28. However, because the support rod 216 is limited by the inner wall of the rotating column 28, the screw 211 will pull the slide plate 213 to slide in the rotating column 28 when it rotates and moves away from the closing plate 212. When the slide plate 213 gradually slides toward the inside of the rotating column 28, the hinge block 214 will push the support rod 216 through the hinge rod 215. When pressure is applied and the support rod 216 is resisted by the inner wall of the rotating column 28, the two ends of the hinged rod 215 are forced to rotate. As the distance between the slide 213 and the inner wall of the rotating column 28 gradually shortens, the rotation of the hinged rod 215 will gradually push the support rod 216 to open, so that the support rod 216 can open the tightening block 218 through the connecting block 217 to tighten the inner diameter of the sheet-like workpiece, avoiding the small internal space causing the bolts to be difficult to tighten. At the same time, the tightening blocks 218 arranged in a circular array can expand proportionally to tighten the inner diameter of the sheet-like workpiece, avoiding the deviation of the workpiece caused by tightening the bolts separately.

[0024] Then the motor 22 is started, and the output shaft of the motor 22 drives the rotating ring 24 and the rotating rod 25 to rotate together through the rotating shaft 23. The rotating rod 25 will drive the shifting rod 26 to shift the transmission block 29 a certain distance only after rotating one circle. By continuously rotating the shifting rod 26, the shifting rod 26 can achieve the same rotation stroke each time it shifts the transmission block 29, thereby achieving the effect of fixed-distance rotation to ensure that the spacing of the workpiece grinding holes is the same, avoiding large errors that affect the position offset of the ground workpiece holes.

[0025] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
