Description

Technical Field

[0001] The utility model relates to the field of fixtures, in particular to a shock-absorbing fixture for fixed machining of a reduction gearbox housing. Background Technique

Using a metal-structured housing can obtain greater strength and stiffness, and has a compact structure and a relatively light weight. There are various structural forms of reduction gearbox housings. When manufacturing in small batches, it is more reasonable to use a welded reduction gearbox housing;

[0003] Among them, the "a shock-absorbing fixture for crankshaft tooling" disclosed in the application number "CN202222355123.X" is also an increasingly mature technology. "The utility model discloses a shock-absorbing fixture for crankshaft tooling, including a crankshaft fixture and a support frame. The support frame is arranged at the bottom of the crankshaft fixture. The crankshaft fixture includes a base, a motor, a transmission gear, a parallel link, a fixing block, a connecting block, a clamping plate, a fixing plate and a fixing frame. The motor is arranged inside the base, the transmission gear is arranged on the top of the motor, the parallel link is movably connected to the outside of the transmission gear, the fixing blocks are arranged at both ends of the parallel link, the connecting block is movably connected to the top of the parallel link, the clamping plate is movably connected to the top of the connecting block, the fixing plate is arranged on the top of the base, and the fixing frame is arranged on the top of the fixing plate.
