Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a grinding wheel assembly for a grinder which is easy to disassemble and replace. Background Art

[0002] A grinder is a device that grinds and polishes the surface of a workpiece using a tool coated or embedded with abrasives. It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in the workpiece. The grinder mainly grinds the surface of the workpiece through the high-speed movement of components such as the grinding wheel. The grinding wheel, as a consumable component, needs to be replaced and other maintenance operations.

[0003] The existing devices mainly fix the grinding wheel on the rotating seat by multiple sets of bolt components, which makes it difficult for some devices to quickly limit the grinding wheel on the rotating seat, resulting in inconvenience in quickly loading and unloading and replacing the grinding wheel. At the same time, some devices mainly install fastening components on the outside of the grinding wheel, which makes some devices easy to loosen after high-speed rotation, thereby causing part of the grinding wheel to fall off during operation, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a grinding wheel assembly that is easy to disassemble and replace for a grinder is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a grinding wheel assembly for a grinder that is easy to disassemble and replace, so as to solve the problem that the existing devices in the prior art mentioned in the above background technology mainly fix the grinding wheel on the rotating seat by multiple groups of bolt components, making it difficult for some devices to quickly limit the grinding wheel on the rotating seat, thereby causing inconvenience in quickly loading and unloading and replacing the grinding wheel. At the same time, some devices mainly install fastening components on the outside of the grinding wheel, making some devices easy to loosen after high-speed rotation, thereby causing part of the grinding wheel to fall off during operation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grinding wheel assembly for a grinding machine that is easy to disassemble and replace, comprising a rotating seat, a fixed rod is fixedly connected to the middle of the left side of the rotating seat, a connecting sleeve is sleeved on the left side of the outer wall of the fixed rod, a grinding wheel is fixedly connected to the middle of the outer wall of the connecting sleeve, the left side of the fixed rod is fixedly connected to a limited seat, and the outer wall of the limited seat is sleeved with a limiting sleeve;

[0006] A limiting mechanism is provided inside the limiting sleeve, and the limiting mechanism includes a clamping block, and the outer wall of the clamping block is fixedly connected to the two sides of the inner wall of the limiting sleeve. A clamping mechanism is provided on the right side of the outer wall of the fixing rod, and the clamping mechanism includes a movable screw barrel, and the right side of the inner wall of the movable screw barrel is movably connected to the right side of the outer wall of the fixing rod.

[0007] Preferably, through grooves corresponding to the clamping block are provided on the upper and lower sides of the outer wall of the limiting seat, and an annular groove corresponding to the clamping block is provided on the right side of the outer wall of the limiting seat.

[0008] Preferably, the front and rear sides of the outer wall of the limiting seat are provided with card slots corresponding to the card blocks, and the card block can pass through the through slot and the annular slot in sequence and be inserted into the card slots.

[0009] Preferably, a first clamp ring is fixedly connected to the right side of the limiting sleeve, a first latch is fixedly connected to the right side of the first clamp ring, and an outer wall of the first latch is inserted into the limiting hole of the connecting sleeve.

[0010] Preferably, the inner wall of the movable screw barrel is threadedly connected with a sliding screw, the inner wall of the sliding screw is sleeved on the outer wall of the fixed rod, and the left side of the sliding screw is fixedly connected with a second clamping ring.

[0011] Preferably, a clamping strip is fixedly connected to the inner wall of the sliding screw, and a limiting sliding groove corresponding to the clamping strip is formed on the outer wall of the fixing rod.

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

[0013] 1. The utility model uses the structures of the card block, the through groove, the annular groove, the card groove, the first clamping ring and the first latch in the limiting mechanism. The limiting sleeve drives the card block to pass through the through groove and the annular groove in sequence and be inserted into the card groove. At the same time, the limiting sleeve drives the first clamping ring to move synchronously, so that the first clamping ring limits the connecting sleeve and the grinding wheel on the outer wall of the fixed rod, thereby realizing the limiting of the grinding wheel. Part of the device can quickly limit the grinding wheel, which is convenient for rapid loading and unloading and replacement of the grinding wheel, thereby improving the efficiency and practicality of the device.

[0014] 2. The utility model uses the structures of the movable screw barrel, sliding screw, second clamping ring, clamping strip and limiting slide groove in the clamping mechanism. By rotating the movable screw barrel clockwise, the movable screw barrel is restricted by the clamping strip and the limiting slide groove, so that the movable screw barrel drives the sliding screw to slide to the left, and the sliding screw drives the second clamping ring to slide synchronously. The second clamping ring cooperates with the first clamping ring to clamp the connecting sleeve and the grinding wheel, thereby clamping the grinding wheel, making it difficult for some fastening components to loosen during high-speed rotation, effectively preventing some grinding wheels from falling off during work, and improving the stability and practicality of the device.

Through this design, the limit sleeve 16 can be limitedly placed on the outer wall of the limit seat 15. The right side of the limit sleeve 16 is fixedly connected with a first clamp ring 25, and the right side of the first clamp ring 25 is fixedly connected with a first latch 26. The outer wall of the first latch 26 is inserted into the limiting hole of the connecting sleeve 13. Through this design, the limit sleeve 16 drives the first clamp ring 25 to clamp the limiting connecting sleeve 13.

[0024] A clamping mechanism 3 is provided on the right side of the outer wall of the fixed rod 12, and the clamping mechanism 3 includes a movable screw barrel 31. The right side of the inner wall of the movable screw barrel 31 is movably connected to the right side of the outer wall of the fixed rod 12.

[0025] Working principle: when the grinding wheel 14 needs to be limited, first, the block 21 is driven to move to the right through the limit sleeve 16, so that the block 21 passes through the through groove 22 and is placed inside the annular groove 23, and then the block 21 is driven to rotate ninety degrees through the limit sleeve 16, so that the block 21 is limited and rotated inside the annular groove 23 and aligned with the slot 24, and finally, the block 21 is driven to move to the left through the limit sleeve 16, so that the block 21 is inserted into the slot 24, and at the same time, the limit sleeve 16 drives the first clamping ring 25 to move synchronously, so that the first clamping ring 25 limits the connecting sleeve 13 and the grinding wheel 14 on the outer wall of the fixed rod 12, thereby realizing the limiting operation of the grinding wheel 14.

[0026] When the grinding wheel 14 needs to be clamped, first rotate the movable screw barrel 31 clockwise. The movable screw barrel 31 is restricted by the clamping strip 34 and the limiting slide groove 35, so that the movable screw barrel 31 drives the sliding screw 32 to slide to the left, and the sliding screw 32 drives the second clamping ring 33 to slide synchronously. The second clamping ring 33 cooperates with the first clamping ring 25 to clamp the connecting sleeve 13 and the grinding wheel 14, thereby realizing the clamping operation of the grinding wheel 14. The operation ends here.
