Description

Technical Field

[0001] This utility model belongs to the field of grinding machine technology, specifically a grinding machine that facilitates the replacement of grinding wheels. Background Technology

[0002] A grinding machine is a machine tool used to grind the surface of a workpiece, mainly for polishing the surface of the workpiece.

[0003] Grinding machines have a wide range of applications. They can perform preliminary shaping and smoothing of cylindrical and conical surfaces, excel at finishing internal cylinders or bores, and manufacture and grind cutting tools. Grinding machines can eliminate rough protrusions on castings and stampings, and can also clean, polish, and grind surfaces. Although initially designed primarily for finishing technology, modern production-grade grinding machines can often handle both roughing and finishing tasks simultaneously. Grinding machines are primarily used for finishing and are known for their structural rigidity. They use grinding wheels composed of fine, extremely hard particles for precision grinding operations. The grinding process is crucial for achieving the desired shape and surface quality of a product. Typically, grinding follows a roughing operation, which removes most of the residual material from the workpiece, and the subsequent grinding operation removes any remaining excess material to create a fine surface.

[0004] After prolonged use, the surface of the grinding wheel on existing grinding machines will be damaged and needs to be replaced. However, the grinding wheel is often used unevenly on one side while the other side is not used. This means that the entire grinding wheel needs to be replaced, which is quite troublesome. Over time, this not only increases expenses but also reduces work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding machine that facilitates the replacement of grinding wheels, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This grinding machine, which facilitates the replacement of grinding wheels, is assembled by connecting the worktable and the fixed plate. The drive motor on the right side of the fixed plate drives the drive wheel shaft to rotate, and the drive wheel shaft is connected to the grinding wheel body via a pulley for transmission. The left side of the grinding wheel body is inserted into the movable base, and the right side of the grinding wheel body is inserted into the connecting slot of the docking protective shell. The connecting slot above the docking protective shell is inserted into the pin above the drive motor to fix the docking protective shell. The docking protective shell and the pin are fixed in position, and the grinding wheel body and the pulley are supported and tightened to prevent the pulley from being too loose and affecting the transmission efficiency. After the grinding wheel body has been used for a period of time, it is pushed inward into the movable base and pulled out from the connecting slot inside the docking protective shell. The left and right sides are then swapped and fixed for continued use. The grinding wheel body is replaced after both sides have been used. When replacing, simply push the grinding wheel body inward into the movable base, remove it from the connecting slot inside the docking protective shell, and replace it with a new grinding wheel body. The movable base has a spring structure, which reduces the cost of grinding wheel replacement and makes replacement more convenient.

[0016] 2. This grinding machine, which facilitates the replacement of grinding wheels, uses a base plate and a stabilizer on the mounting base to support and stabilize the grinding wheel body above it. The rotating bearings evenly distributed inside the stabilizer contact the outer surface of the grinding wheel body, making the grinding wheel body rotate more smoothly. By placing the workpiece to be processed on the sliding plate and then using the operation of the electric push rod on the connecting plate to push the push rod inward, the workpiece is clamped by the clamping plate. By gripping the handle and moving upward, the grinding wheel body above can be used to grind the surface of the workpiece. During use, the operator's hands can be kept away from the grinding wheel body, improving safety. Attached Figure Description
