Description

Technical Field

[0001] This utility model relates to the field of motor housing blank technology, and in particular to a motor housing blank grinding equipment. Background Technology

[0002] A motor shell blank refers to the preliminary shape and semi-finished product used to create the motor casing during the motor manufacturing process. The motor casing is typically formed by metal casting and pressing, while the shell blank is the first step in this process, usually obtained through casting, stamping, and extrusion. Grinding equipment is a type of machinery used to process the surface of an object through friction. The grinding process typically utilizes the contact between abrasive and the workpiece surface to remove irregularities, burrs, rust, dirt, and other uneven parts, thereby improving the surface quality of the object, making it smooth and flat, and meeting specific dimensional and appearance requirements.

[0003] In the prior art, some grinding equipment usually has a fixed grinding angle. The contact angle between the workpiece and the abrasive is kept consistent by adjusting the working platform and support of the equipment. Its main structure includes a motor, abrasive, adjustment device and support frame, etc. The motor drives the abrasive to rotate, and the abrasive rubs against the surface of the workpiece, thereby removing surface irregularities and achieving smoothing.

[0004] However, in actual use, some equipment usually has a fixed grinding angle, which means that when workers are grinding, they can only grind at a fixed angle. This limits the flexibility and precision of grinding, and greatly increases the difficulty and labor intensity of the workers. In order to address the above problems, a grinding equipment for motor housing blanks is proposed. Utility Model Content

[0038] Working principle: First, the equipment starts the second motor 12, which causes the second rotating connecting shaft 13 to drive the first bevel gear 14 to rotate. Through meshing, the second bevel gear 16 rotates, and the rotational force is transmitted to the drive connecting column 17 through the rotating connecting column 15. This drives the connecting column 17 to move the grinding disc 18 to adjust the grinding angle. Then, the first motor 7 is started, and driven by the first rotating connecting shaft 8, the grinding disc 18 rotates 390 degrees, achieving the multi-angle grinding effect of the equipment.

[0039] At the same time, the equipment starts the third rotating connecting shaft 21 through the third motor 20, which drives the rotating connecting plate 22 to rotate, causing the fixed limiting post 23 to rotate accordingly. Since the fixed limiting post 23 rotates under the restriction of the sliding connecting plate 24, the sliding connecting plate 24 converts the rotational force into the sliding force of the sliding connecting plate 24, causing the cleaning brushes 28 on the left and right sides to slide back and forth on the support operating table 1, thereby cleaning the grinding debris on the support operating table 1.

[0040] In addition, the lifting mechanism of the equipment includes a cylinder 3, and the driving end of the cylinder 3 is fixedly connected to a connecting telescopic column 4. When the cylinder 3 works, it drives the connecting telescopic column 4 to extend or retract, thereby driving the connecting sliding plate 5 and the first fixed connecting plate 6 connected thereto to move up and down, so as to adjust the height of the grinding mechanism to meet the grinding needs of motor shell blanks of different heights.
