Drilling equipment for differential case

Abstract

The invention provides efficient and high-precision equipment for drilling a differential housing. The efficient and high-precision equipment for drilling the differential housing comprises a base, asupport table, a workpiece clamping mechanism for clamping the differential housing, a perforating mechanism and a locating mechanism. The support table is vertically arranged on the base. The workpiece clamping mechanism is arranged on the support table, and the differential housing can be driven to rotate in a stepping type manner by the workpiece clamping mechanism. The perforating mechanism comprises two perforating motors, two drill bits connected with the perforating motors respectively, a linkage plate and a moving assembly. According to the efficient and high-precision equipment for drilling the differential housing, two drilled holes are symmetrically formed in two sides of the axis of the differential housing so that two holes can be drilled simultaneously by one-time driving, and perforating efficiency is high; after a first set of holes are drilled, a locating rod is utilized to penetrate through the first set of holes so that the differential housing does not rotate; and besides, because locating holes which the locating rod penetrates through and drilled holes which the drill bits penetrate through are on the circumference which encircles around the center of the differential housing so that each circumferential drilled hole is distributed with equal angles around the center of the differential housing, and the drilling precision is high.

Description

technical field [0001] The invention relates to the technical field of differential case processing, in particular to a differential case drilling device. Background technique [0002] The differential is a machine that produces a speed difference. Its two output shafts can move at different speeds, but the output torque of the two shafts must be strictly kept the same. The differential on the car is important for the traction and stability of the car. , Passability, etc. have a very important impact, therefore, the dimensional accuracy and machining accuracy of the differential case are required to be very high in the process of manufacturing. [0003] There are also some equipment used for differential case drilling in the market, such as the drilling jig of a kind of differential case whose Chinese patent publication number is CN206855033U, including "cylindrical body and cover body, the top inside of the cylindrical body A first annular groove is provided, the top of th...

Problems solved by technology

[0004] But above-mentioned application also has several problems in use: the first, when clamping the differential case, owing to be to clamp the edge of differential case up and down, there is the rotation of differential case in drilling process. Hidden dangers affect drilling accuracy

Second, after the differential case is clamped, manual hand-held drilling equipment is required to drill holes one by one. The drilling efficiency is low, time-consuming and labor-intensive, and the holes are easily deflected by manual operation.
