Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to the structure of a grinding machine worktable and a grinding machine. Background Technology

[0002] Grinding machines are machine tools that use abrasives to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasives and free abrasives such as oilstones, belt abrasives, honing machines, ultra-precision machining tools, belt grinding machines, grinding machines, and polishing machines.

[0003] Grinding machines can process materials with high hardness, such as hardened steel and cemented carbide; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, as well as high-efficiency grinding, such as heavy-duty grinding.

[0004] With the increasing number of high-precision, high-hardness mechanical parts and the development of precision casting and forging processes, the performance, variety, and output of grinding machines are constantly improving and growing. Based on the motion characteristics and process requirements of grinding machines, the following requirements apply to electric drive and control: 1. The rotational motion of the grinding wheel generally does not require speed regulation; it can be driven by a single three-phase asynchronous motor, and only unidirectional rotation is required. For larger capacities, a delta-type reduced-voltage start can be used. 2. To ensure machining accuracy, smooth operation, and minimal inertia and impact during the reciprocating motion of the worktable, hydraulic transmission is used to realize the reciprocating motion of the worktable and the transverse feed of the grinding wheel head.

[0005] Existing grinding machine table structures have certain limitations in terms of accuracy, stability, and processing efficiency. For example, the transmission system of some tables is prone to crawling and vibration, which affects the processing quality. In addition, traditional grinding machines lack the flexibility and adaptability of the table when processing complex-shaped workpieces, making it difficult to meet the requirements of high-precision processing. Therefore, it is necessary to improve the grinding machine table structure and the grinding machine itself to address these issues. Utility Model Content

A processing panel 208 is fixedly connected to the top of the threaded block 204. By utilizing the transmission mechanism composed of the motor 202, the lead screw 203, and the threaded block 204, as well as the support frame composed of aluminum profiles, the transmission system and support structure of the worktable can be optimized, improving the processing accuracy and stability of the grinding machine, while enhancing its adaptability to complex workpieces. Through the above-mentioned optimized structure, the worktable achieves high-precision and high-stability processing.

[0030] The base frame 101 is made of aluminum alloy. A plastic-coated slide rail 205 is fixedly connected to the top of the base frame 101. A slider 206 is slidably connected to the top of the plastic-coated slide rail 205. The slider 206 is fixedly connected to the processing panel 208. A limit plate 209 is fixedly connected to the top of the base frame 101. A bearing seat 207 is fixedly connected to the top of the mounting bracket 201. The lead screw 203 extends into the interior of the bearing seat 207. The support structure is made of high-strength aluminum alloy, which reduces weight while improving rigidity.

[0031] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the lifting assembly 3 includes a side plate 301, a slide rail 303 fixedly connected to the side of the side plate 301, a sliding block 304 slidably connected to the side of the slide rail 303, a combination block 306 fixedly connected to the side of the sliding block 304, a top plate 302 fixedly connected to the top of the side plate 301, a telescopic rod 305 installed on the side of the top plate 302, and the output end of the telescopic rod 305 fixedly connected to the combination block 306.

This allows for position adjustment of the processing panel 208 and optimization of the processing position. The extension of the telescopic rod 305 controls the combination block 306 to slide along the slide rail 303 via the sliding block 304, thereby causing the rotary motor 308 inside the clamp 307 to move downwards, bringing the grinding wheel 309 closer to the workpiece. The rotary motor 308 is then started to rotate the grinding wheel 309, thus grinding the workpiece. Optimizing the transmission system and support structure of the worktable improves the processing accuracy and stability of the grinding machine.
