Description

Technical Field

[0001] The utility model relates to the technical field of motor parts processing, in particular to a motor plastic parts processing cutter. Background Art

[0002] Plastic is a high molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Plastic parts are made of plastic. Some parts in motors use plastic parts, and plastic parts need to be cut during processing.

[0003] The publication number CN 219685739 U discloses a plastic parts processing cutter, including a support foot, a moving mechanism and a cutting mechanism are arranged above the support foot; the moving mechanism includes a moving part and a clamping part; the clamping part is arranged above the moving part; the cutting mechanism includes a fixed part and a cutting part; the cutting part is arranged above the fixed part, and a rack is arranged on the back of the moving plate. By arranging a rack on the back of the moving plate and meshing a gear on the surface of the rack, the motor can control the gear to drive the moving plate to move toward the cutting part, avoiding manual advancement for cutting; by arranging a support and arranging a support plate on the top surface of the support, the clamping plate can be pushed to clamp the plastic parts by controlling the electric telescopic rod on the top surface of the support plate, and manual hand-held cutting is no longer required; by arranging a linear screw motor to push the cutting knife downward to cut the plastic parts, and manual cutting is no longer required.

[0004] However, the cutter has the following shortcomings: when the device is in use, the electric telescopic rod drives the clamping plate to clamp and fix one side of the plastic part. However, due to the long size of some parts, the cutter will squeeze the parts when cutting them, causing them to be offset and misaligned. Even when the cutter is reset upward, it will drive the parts to bend upward, causing them to deform and break, affecting the yield rate of the parts.

[0005] Therefore, the utility model provides a motor plastic parts processing cutter to solve the above problems. Utility Model Content
