Description

Technical Field

[0001] The invention relates to the technical field of metal punching, in particular to a device for punching a reducer housing. Background Art

[0002] The drilling of reducer housing is an important process in the manufacturing and maintenance of reducer, which is mainly used for installation, ventilation, heat dissipation and lubrication. The housing of the reducer is usually made of cast iron or aluminum alloy, which has good strength and wear resistance. Since the reducer housing is mostly a circular curved surface, it requires a lot of auxiliary tools to drill holes at equal distances on its end face, which is time-consuming and labor-intensive, and requires high technical skills of the operator. On the other hand, some reducer housings are special-shaped, and the two circular curved surfaces may not have the same axis, which brings troubles to the design of the clamping tool.

[0003] The utility model with authorization announcement number CN219787345U discloses a processing device for drilling holes in a reducer housing. The utility model fixes the reducer housing on the top surface of the base through a clamping mechanism. The reducer housing is located below the driving mechanism. The lifting mechanism drives the driving mechanism to move vertically, so that the drill bit and the surface of the reducer housing are in contact to realize the drilling operation on the reducer housing.

[0004] The above-mentioned device can clamp and punch holes on the reducer housing, but the device can only clamp the reducer housing with the same outer diameter. On the one hand, the single-point clamping is not stable and is prone to displacement during punching. On the other hand, when the reducer housing is an eccentric special-shaped housing, the device cannot perform stable clamping. Moreover, the device lacks a device for calibrating the equidistant displacement of the punching mechanism, and cannot perform equidistant punching operations on the reducer housing.
