Description

Technical Field

[0001] This utility model relates to the field of motor shaft processing devices, and in particular to a rough milling auxiliary device for processing new energy motor shafts. Background Technology

[0002] In the field of new energy motor manufacturing, the machining accuracy and efficiency of shafts directly affect motor performance. Traditional rough milling often uses single-point fixing or manual clamping of shafts, which has significant technical drawbacks: First, the shaft requires repeated position adjustments during clamping, which is time-consuming and makes it difficult to ensure symmetry, leading to machining deviations; second, rigid clamping devices easily leave indentations on the shaft surface, especially causing severe damage to high-precision coated shafts; third, there is a lack of rapid limiting mechanisms, requiring operators to rely on experience for manual alignment, resulting in poor consistency. While some existing automated fixtures use hydraulic clamping, their complex structure, high maintenance costs, and inability to adapt to shafts of different diameters are significant issues. Furthermore, traditional devices often perform single-axis machining, requiring frequent changes of equipment during mass production, leading to low efficiency. There is an urgent need for an auxiliary device that integrates rapid positioning, flexible clamping, and multi-axis synchronous machining to address the problems of low efficiency, high damage rates, and poor adaptability in existing technologies. Utility Model Content

[0003] This application provides a rough milling auxiliary device for machining the shaft of a new energy motor, which solves the technical problems of existing automated fixtures, which, although using hydraulic clamping, have complex structures, high maintenance costs, and cannot be adapted to shafts of different diameters. At the same time, traditional devices mostly perform single-axis machining, requiring frequent changes of equipment in mass production, resulting in low efficiency.

[0004] The technical solution adopted in the embodiments of this application is as follows:

[0005] A rough milling auxiliary device for machining a new energy motor shaft includes a base plate, a support block for supporting the motor shaft, a limiting block for limiting the position of the motor shaft, and a clamping device for pressing the motor shaft. Two sets of symmetrically arranged clamping devices are arranged on the top of the base plate. Support blocks are arranged on both sides of each set of clamping devices. Two sets of symmetrically arranged limiting blocks are arranged on one side of the top of the base plate. The two sets of limiting blocks are respectively close to their corresponding support blocks. Grooves are formed on the support blocks. The clamping device includes a clamping block and a driving device mounted on the top of the base plate. The clamping block is located on the driving end of the driving device, with both ends of the clamping block positioned directly above the two sets of support blocks symmetrically arranged with the driving device.

[0006] A further technical solution is that the driving device is a cylinder.

[0007] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0008] 1. This device, employing a base plate, support blocks, limit blocks, and clamping mechanism, achieves rapid centering and positioning of the rotating shaft through symmetrically arranged support and limit blocks, eliminating manual adjustment errors and significantly improving positioning accuracy. The drive unit synchronously presses down the clamping blocks, ensuring balanced clamping force across both axes and preventing shaft deformation or surface damage caused by unilateral overpressure. The synergistic design of the rubber pads and limit blocks provides both cushioning protection and ensures axial positioning stability, suitable for flexible clamping of shafts of different diameters. The modular structure supports rapid assembly and is adaptable to mass production of various products, significantly shortening the processing cycle. The overall design, through a combination of rigidity and flexibility and symmetrical drive, overcomes the technical challenges of low efficiency, high damage rate, and poor adaptability of traditional devices, providing a reliable solution for high-precision manufacturing of new energy motors.
