Description

Technical Field

[0001] This utility model mainly relates to the technical field of positioning fixtures, specifically a positioning fixture for a new energy motor housing. Background Technology

[0002] In the processing and assembly of new energy motor housings, positioning fixtures are core tools for ensuring the accuracy of key dimensions such as coaxiality and perpendicularity between the housing and internal components. However, existing motor housing positioning fixtures generally suffer from insufficient compatibility. Traditional fixtures are typically designed for a single model or size of motor housing, with a fixed structure that cannot adapt to housings of different specifications. When the product model changes, the fixture must be redesigned or replaced, leading to increased production costs and reduced production efficiency.

[0003] Furthermore, some tooling fixtures, due to insufficient structural rigidity or uneven clamping force distribution, are prone to causing housing vibration or deformation during processing, further reducing the finished product qualification rate. Therefore, there is an urgent need for a new energy motor housing positioning tooling with high compatibility, high positioning accuracy, and stable structure. Utility Model Content

The three-jaw cylinder 510 can drive the positioning block 520 to retract or extend in a concentric manner to accurately position the inner ring of the motor housing.

[0029] The hand-cranked moving assembly 600 of this embodiment includes a profile beam 610, a wheel mounting plate 620, a shaft fixing seat 630, a transverse plate 640, a linear bearing 650, a guide shaft 660, a handwheel 670, a synchronous belt assembly 680, and a locking bearing seat 690. The wheel mounting plate 620 is installed at both ends of the profile beam 610. The shaft fixing seats 630 are arranged and fixed on the wheel mounting plate in sequence. The two ends of the guide shaft 660 are respectively mounted on the shaft fixing seats 630. The linear bearing 650 passes through the guide shaft 660. The transverse plate 640 is mounted above the linear bearing 650 and can move axially along the guide shaft 660. The synchronous belt assembly 680 is installed on the wheel mounting plate 620. The locking bearing seat 690 is fixed below the wheel mounting plate 620. This design is simple and easy to operate.

[0033] The specific operation method of this utility model is as follows: During use, the operator places the new energy motor housing on the upper mounting plate 100. The three-claw cylinder 510 drives the positioning block 520 to extend outward and align the inner ring of the motor housing. Then, the operator drives the rotating pressing component 400 by turning the handwheel 670. After the rotating pressing component 400 moves to the appropriate position, the rotating pressing cylinder 420 drives the rubber block 430 to press down, firmly fixing the motor housing on the upper mounting plate 100. When switching to motor housings of different sizes, only the positioning block 520 in the claw component 500 needs to be replaced to achieve compatible alignment. By turning the handwheel 670 to change the distance between the two sets of rotating pressing components 400, motor housings of different diameters can be accommodated. The operation is convenient and can greatly improve production efficiency.
