Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile parts assembly and manufacturing, and particularly relates to an automobile part tooling fixture. BACKGROUND

[0002] The flywheel housing is installed between the engine and the gearbox, is connected with the crankcase, the engine and the oil pan, and internally has a flywheel assembly to connect the engine body, provide protection and serve as a carrier. The flywheel housing needs to be clamped by a fixture during manufacturing.

[0003] A flywheel housing foot hole punching fixture is disclosed in Chinese patent CN201821165108.6, which comprises a vertically arranged mounting plate and a support plate arranged at the bottom of the mounting plate. The plate surfaces of the mounting plate and the support plate are perpendicular to each other. The mounting plate is provided with a positioning plate that abuts against the flywheel housing foot. The positioning plate is provided with a positioning hole corresponding to the position of the flywheel housing foot. The bottom of the flywheel housing, the foot and the end face opposite to the side where the foot is located abut against the mounting plate, the positioning plate and the support plate, respectively, to form effective clamping. Then, the positioning hole on the positioning plate is aligned and punched using an electric drill to obtain the foot hole.

[0004] With further research, the applicant found that the flywheel housing manufacturing fixture uses a bolt clamp block for clamping, which needs to be turned back and forth, and is very inconvenient when clamping the flywheel housing, thereby reducing the efficiency of flywheel housing manufacturing and processing.

[0016] Furthermore, a connecting seat is connected to the base, and the guide rod is inserted into the connecting seat.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] This invention utilizes multiple clamping components that cooperate with the support base to quickly clamp the flywheel housing via a pressing mechanism. The guide rod ensures the workpiece is centered on the base during placement, allowing for even clamping by the multiple components. The locating pin engages with a locating through-hole on the bottom of the workpiece, securing it in place and facilitating subsequent drilling and other machining operations. Compared to existing fixtures, this eliminates the need for repeated bolt operations, thus improving the manufacturing efficiency of the flywheel housing. Attached Figure Description
