Description

Technical Field

[0001] This utility model relates to the field of spindle grinding wheel rod protective cover device, and in particular to a novel spindle grinding wheel rod protective cover structure. Background Technology

[0002] Traditional grinding equipment generally suffers from problems such as complex structure, inconvenient maintenance, and safety hazards. For example, existing protective cover lifting mechanisms mostly rely on hydraulic systems, requiring complex piping and power units. This not only occupies a large space but is also prone to frequent malfunctions due to oil leaks or component wear, resulting in high maintenance costs. In addition, the grinding wheel replacement process is cumbersome. Traditional covers require complete disassembly of the bolted fixing structure, which is time-consuming and labor-intensive, making it unsuitable for scenarios involving frequent grinding wheel replacements.

[0003] In terms of adaptability, traditional equipment, due to its fixed housing size, cannot accommodate grinding wheel rods of different lengths or grinding wheels of different diameters, thus limiting the diversity of processing. Safety is also a concern; some equipment uses manually raised protective covers, which have a slow response speed and cannot quickly cover the grinding wheel when not in operation, increasing the risk of operators accidentally touching the high-speed rotating grinding wheel.

[0004] Therefore, there is an urgent need for a grinding wheel equipment that is compact, easy to maintain, highly adaptable, and safe, in order to solve the above-mentioned technical pain points. Utility Model Content

[0005] This application provides a novel spindle grinding wheel rod protective cover structure, which solves the technical problem that existing grinding equipment cannot be compatible with grinding wheel rods of different lengths or grinding wheels of different diameters due to the fixed size of the cover, thus limiting the diversity of processing. At the same time, there are also safety defects. Some equipment uses a manual lifting protective cover, which has a slow response speed and cannot quickly cover the grinding wheel when not in operation, resulting in a high risk of operators accidentally touching the high-speed rotating grinding wheel.

[0006] The technical solution adopted in the embodiments of this application is as follows:

[0007] A novel spindle grinding wheel rod protective cover structure includes an upper grinding head seat, a lower grinding head seat, an electric spindle, a grinding wheel rod, a grinding wheel, a bent connecting rod, a cover, set screws, a mounting plate, connecting screws, a rotary cylinder flange, a rotary cylinder, and a cylinder mounting plate. The electric spindle is disposed between the upper and lower grinding head seats. One end of the grinding wheel rod is connected to the grinding wheel, and the other end is mounted on the output end of the electric spindle. The cover is connected via a plug-in connection at one end of the bent connecting rod and secured with set screws. The other end of the bent connecting rod is fixed to the mounting plate. The mounting plate is connected to the rotary cylinder flange via connecting screws. The rotary cylinder is fixed to the top of the upper grinding head seat via the cylinder mounting plate and secured with connecting screws. The output end of the rotary cylinder drives the rotary cylinder flange to rotate clockwise or counterclockwise, thereby raising or lowering the cover.

[0008] A further technical solution is that the rotary cylinder adopts a semi-naked structure, which is directly exposed to the outside, making it easy to observe the wear status of the grinding wheel.

[0009] A further technical solution is that the rotation stroke of the rotary cylinder is limited, and the lifting and lowering of the cover can be completed by only a small range of rotation.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] 1. By adopting an upper grinding head holder, lower grinding head holder, electric spindle, grinding wheel rod, grinding wheel, bent connecting rod, cover, set screw, mounting plate, connecting screw, rotary cylinder flange, rotary cylinder, and cylinder mounting plate, the practicality, safety, and economy of the equipment are significantly improved through structural optimization. The plug-in cover and set screw enable quick grinding wheel replacement, saving maintenance time; the cover can be adjusted forward and backward to accommodate different grinding wheel rod lengths and grinding wheel diameters, expanding the processing range. The use of a rotary cylinder instead of a traditional hydraulic mechanism simplifies the structure, reduces manufacturing costs and failure rate; the semi-exposed design allows for direct observation of the grinding wheel wear condition, improving maintenance efficiency. The short stroke design of the rotary cylinder minimizes the space required for cover lifting, avoiding interference with the headstock and making it suitable for compact environments. The automatic lifting mechanism quickly covers the grinding wheel when not in operation, effectively preventing accidental contact and significantly reducing safety risks. This invention combines high efficiency, flexibility, and safety, and has broad industrial application value. Attached Figure Description

At the same time, there are also safety defects. Some equipment uses a manual lifting protective cover, which has a slow response speed and cannot quickly cover the grinding wheel when not in operation, resulting in a high risk of operators accidentally touching the high-speed rotating grinding wheel.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] A novel spindle grinding wheel rod protective cover structure, such as Figure 1 , Figure 2 and Figure 3 As shown, the assembly includes an upper grinding head holder 1, a lower grinding head holder 2, an electric spindle 3, a grinding wheel rod 4, a grinding wheel 5, a bent connecting rod 6, a cover 7, a set screw 8, a mounting plate 9, a connecting screw 10, a rotary cylinder flange 11, a rotary cylinder 12, and a cylinder mounting plate 13. The electric spindle 3 is located between the upper grinding head holder 1 and the lower grinding head holder 2. One end of the grinding wheel rod 4 is connected to the grinding wheel 5, and the other end is installed at the output end of the electric spindle 3. The cover 7 is connected to the bent connecting rod 6 via a plug-in connection and is secured by the set screw 8. The other end of the bent connecting rod 6 is fixed to the mounting plate 9. The mounting plate 9 is connected to the rotary cylinder flange 11 via the connecting screw 10. The rotary cylinder 12 is fixed to the top of the upper grinding head holder 1 via the cylinder mounting plate 13 and secured by the connecting screw 10. The output end of the rotary cylinder 12 drives the rotary cylinder flange 11 to rotate clockwise or counterclockwise, thereby lifting or lowering the cover 7.

[0020] The rotary cylinder 12 adopts a semi-naked structure, which is directly exposed to the outside, making it easy to observe the wear status of the grinding wheel 5.

[0021] The rotary cylinder 12 has a limited rotation stroke, and only a small range of rotation is needed to complete the lifting and lowering of the cover 7.

[0022] This embodiment provides a grinding wheel rod grinding device, including an upper grinding head seat 1, a lower grinding head seat 2, an electric spindle 3, a grinding wheel rod 4, a grinding wheel 5, a bent connecting rod 6, a cover 7, set screws 8, a mounting plate 9, connecting screws 10, a rotary cylinder flange 11, a rotary cylinder 12, and a cylinder mounting plate 13.

During operation, the rotary cylinder 12 drives the rotary cylinder flange 11 to rotate clockwise, which raises the cover 7 to expose the grinding wheel 5 for grinding. When changing the grinding wheel, it is only necessary to loosen the set screw 8 and pull out the cover 7 without disassembling the entire structure. When not in operation, the rotary cylinder 12 rotates counterclockwise, and the cover 7 is lowered to cover the grinding wheel 5 to prevent accidental contact.

[0023] Operating procedures

The pluggable cover 7, in conjunction with the set screw 8, enables quick replacement of the grinding wheel 5, saving maintenance time; the cover 7 can be adjusted forward and backward to accommodate different grinding wheel rod lengths 4 and grinding wheel 5 diameters, expanding the processing range. The use of a rotary cylinder 12 instead of a traditional hydraulic mechanism simplifies the structure and reduces manufacturing costs and failure rates; the semi-exposed design allows for direct observation of the grinding wheel 5's wear condition, improving maintenance efficiency. The short stroke design of the rotary cylinder 12 minimizes the space required for lifting the cover 7, avoiding interference with the headstock and making it suitable for compact environments.
