Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a CNC cylindrical grinding machine with a clamping mechanism. Background Technology

[0002] CNC cylindrical grinding machines are pre-programmed according to machining requirements, and the control system issues numerical information commands to perform the machining. They are mainly used for grinding cylindrical and conical outer surfaces. In the current CNC cylindrical grinding process, different types of clamping mechanisms are often required for workpieces of different shapes and sizes. However, traditional clamping mechanisms have certain limitations in terms of versatility, ease of adjustment, and clamping stability.

[0003] A search revealed a patent with application number CN202223160518.0, which discloses a CNC cylindrical grinding machine for automotive parts, belonging to the field of automotive parts processing equipment. The machine includes a base with two symmetrically distributed mounting seats fixedly installed at its top. A cylinder is fixedly mounted on one of the mounting seats away from the other, and the cylinder piston shaft slides through the mounting seats in the same group. A clamping assembly is provided between the end of the cylinder piston shaft passing through the mounting seat and the other mounting seat. However, in practical use, the above patent has the following drawbacks: it is inconvenient to replace the grinding plate; after the grinding plate wears down, it requires considerable time and effort to disassemble and replace, affecting processing efficiency. Therefore, we propose a CNC cylindrical grinding machine with a clamping mechanism. Utility Model Content

[0006] Furthermore, the clamping mechanism includes a mounting plate, a fixed base, a cylinder, a rotary motor, a three-jaw chuck, and a ejector pin. The mounting plate and the fixed base are fixedly connected to the left and right sides of the top of the base, respectively. A cylinder is fixedly connected to the left side of the mounting plate.

[0007] Furthermore, the quick-release assembly includes a limiting sleeve, a plug-in block, a slot, a through port, a sliding groove, a sliding column, a slider, a lifting plate, a plug-in block, a threaded block, a bolt, and a fixing groove. The left and right sides of the grinding plate are fixedly connected to the limiting sleeve. The front and rear sides of the limiting sleeve are open structures. The plug-in block is movably plugged into the limiting sleeve. The rear side of the plug-in block is fixedly connected to the front side of the fixing plate.

[0008] Furthermore, the top of the plug block is provided with a slot, and the top of the limiting sleeve is provided with an opening corresponding to the slot. Two sliding grooves are symmetrically provided on the front side of the fixing plate. The top and bottom of the inner wall of the sliding groove are fixedly connected by a sliding column. A slider is slidably connected below the surface of the sliding column. The slider is movably connected to the sliding groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features a quick-release assembly. When the grinding plate needs replacement due to wear, the bolt is turned counterclockwise to disengage it from the fixing groove. Then, the lifting plate is pulled upwards, causing the lifting plate, slider, and locking block to move upwards. Simultaneously, the spring is compressed, disengaging the locking block from the slot and opening. The grinding plate is then pulled forward, disengaging the insertion block from the limiting sleeve, allowing the grinding plate to be removed. To install a new grinding plate, it is placed in front of the fixing plate, with the insertion block inserted into the corresponding limiting sleeve. The lifting plate is then released, and the spring force causes the lifting plate and locking block to return to their original position, locking the locking block into the slot. Finally, the bolt is turned clockwise to engage the bolt's rear end in the fixing groove, thus securing the threaded block and lifting plate. This completes the quick installation of the grinding plate, offering simple and convenient operation, significantly improving replacement efficiency, and reducing processing time lost due to grinding plate replacement.

[0028] In practical applications: When in use, one end of the workpiece is clamped and fixed by the three-jaw chuck 205. The cylinder 203 drives the rotary motor 204 and the three-jaw chuck 205 to move, so that the other end of the workpiece abuts against the ejector pin for fixation. The electric push rod 7 pushes the fixing plate 8 and the grinding plate 9 to move, so that the grinding plate contacts the workpiece. Then, the rotary motor 204 drives the workpiece to rotate and grind the workpiece. At the same time, the servo motor 4 can drive the lead screw 5 to rotate, so that the thread seat 6 moves left and right in the guide groove 3, enabling the equipment to grind different positions of the product. When the grinding plate 9 is worn and needs to be replaced, turn the bolt 111 counterclockwise to disengage it from the fixing groove. Then, pull the lifting plate 108 upward, which will cause the lifting plate, slider, and locking block to move upward. At the same time, compress the sleeve spring, which will cause the locking block 109 to disengage from the slot 103 and the through hole. Then, pull the grinding plate forward to disengage the insertion block from the limiting sleeve, so that the grinding plate 9 can be removed. When installing a new grinding plate 9, place the grinding plate 9 in front of the fixing plate 8 and insert the insertion block 102 into the corresponding limiting sleeve 101. Then, release the lifting plate, which will cause the lifting plate and locking block to return to their original position under the action of the sleeve spring. This will cause the locking block 109 to engage in the slot 103. Then, turn the bolt 111 clockwise to engage the rear end of the bolt 111 in the fixing groove 112, thereby fixing the threaded block 110 and the lifting plate 108, and completing the quick installation of the grinding plate 9.
