Description

Technical Field

[0001] This utility model relates to the technical field of steel grinding and processing equipment, and in particular to a grinding wheel stabilization installation mechanism. Background Technology

[0002] In precision grinding of steel plates, traditional grinding spindles typically use narrow-width grinding wheels (90mm) and rely on a single-sided cantilever support structure, which limits processing efficiency. Due to the small wheel coverage area, grinding large steel plates requires multiple passes, significantly extending processing time. Furthermore, the single-sided support structure lacks rigidity, easily causing vibration and runout during high-speed spindle rotation. Therefore, the speed is usually limited to below 1000 RPM, far below the requirements of modern high-speed grinding (above 5000 RPM). Low-speed grinding not only reduces material removal rate but can also lead to unstable surface quality and even workpiece burning. This structure restricts the processing efficiency of steel plate grinding and makes it difficult to meet the demands of high-efficiency production. Utility Model Content

The output shaft of the spindle motor 2 is parallel to the spindle 4. The output shaft of the spindle motor 2 is connected to a first synchronous pulley 21. A second synchronous pulley 6 is fixedly sleeved on the first end of the spindle 4. The first synchronous pulley 21 and the second synchronous pulley 6 are connected by a synchronous belt (not shown). The spindle motor 2 can drive the spindle 4 to rotate through the synchronous belt to realize the rotational grinding function of the grinding wheel 5.

The machine tool 9 is provided with a plate mounting table 91, which is equipped with a clamp. The steel plate is clamped on the plate mounting table 91, and the grinding wheel 5 is located above the plate mounting table 91. The grinding wheel 5 contacts the steel and can perform grinding processing.

[0031] refer to Figure 4A grinding wheel mounting part 41 is provided on the spindle 4. One side of the grinding wheel mounting part 41 is a shoulder 42, and the other side is a positioning sleeve 43. The grinding wheel 5 is connected to the grinding wheel mounting part 41 by a key. The grinding wheel 5 can rotate synchronously with the spindle 4, and the grinding wheel 5 is confined between the shoulder 42 and the positioning sleeve 43. The spindle 4 is provided with two rotating connecting parts, including a first rotating connecting part 44 and a second rotating connecting part 45. The first rotating connecting part 44 is located near the shoulder 42, and the second rotating connecting part 45 is located near the positioning sleeve 43.

[0032] Furthermore, the mounting plate 1 is provided with two positioning seats 3, which support the spindle 4 respectively. The grinding wheel 5 is fixedly sleeved between the two positioning seats 3. The two positioning seats 3 can support the spindle 4 from both ends, forming a double-sided fixed structure, which can improve the support stability of the spindle 4. The spindle 4 with a double-sided fixed structure can stably install a wide grinding wheel 5. The use of a wide grinding wheel 5 can expand the processing coverage area of ​​the grinding wheel, allowing a wider processing surface to be processed in a single grinding operation, effectively improving processing efficiency. In this embodiment, the width of the grinding wheel 5 is 255mm.

[0033] Specifically, the positioning seat 3 includes a fixed part 31 and a movable part 32, with the movable part 32 located above the fixed part 31. The upper part of the fixed part 31 is provided with a semi-circular upper groove, and the lower part of the movable part 32 is provided with a semi-circular lower groove. The upper groove and the lower groove are combined to form a socket hole, which is used to accommodate the passage of the spindle 4.

The spindle 4 can be directly taken out from the lower groove of the fixed part 31, which facilitates the replacement of the grinding wheel 5, shortens the equipment maintenance time, and improves production efficiency.

[0035] In this embodiment, the spindle 4 of the grinding wheel stabilizing mounting mechanism is rotatably supported by two positioning seats 3, forming a double-sided fixed structure, which greatly improves the support stability of the spindle 4. The double-sided fixed structure of the spindle 4 allows for the stable mounting of wide-width grinding wheels. The use of wide-width grinding wheels expands the processing coverage area of ​​the grinding wheel 5, enabling a wider processing surface to be handled in a single grinding operation, effectively improving processing efficiency. Furthermore, the positioning seats of this grinding wheel stabilizing mounting mechanism include a fixed part 31 and a detachable movable part 32. After removing the movable part 32, the spindle 4 can be pulled away from the positioning seat 3, facilitating the replacement of the grinding wheel 5 and shortening equipment maintenance time.

Similarly, pin holes are provided at the top of the upper bearing 72 and the top of the upper groove of the movable part 32, respectively. The two ends of the positioning pin can be inserted into the upper bearing 72 and the upper groove of the movable part 32, respectively, to achieve positioning between the upper bearing 72 and the movable part 32. When the main shaft 4 rotates, the bearing 7 and the positioning seat 3 remain relatively stationary, while the rotating connecting part of the main shaft 4 can rotate relative to the bearing 7.

[0039] Example 3

[0040] Unlike Example 1, the reference Figure 6 An oil cup 8 is fixedly installed on the upper part of the movable part 32.
