Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] For the sake of illustration, first combine the Figures 1a-1d The structure of processed gearbox case is introduced. As shown in the figure, a boss 10 is provided on one side of the machined gearbox case, and the side with the boss 10 is used as the installation surface H. A plurality of bearing holes are opened on the gearbox casing, wherein the coaxiality error of the bearing holes 2 and 3 is very small, and the verticality error relative to the mounting surface H is very small. Bearing bores 2 and 3 are arranged coaxially with a common axis Z. The parallelism error of the axes of the bearing holes 4 and 5 relative to the axis Z is very small, and the position dimension X 1 high precision requirements. The verticality error of the axes of bearing holes 6, 7, 8, and 9 relative to the axis Z and the parallelism error of th...

The invention discloses a processing method of a gear box body. The method comprises the following steps of: (1) processing a positioning pin hole on a first side surface, with a boss, of a gear box body to be processed, and processing coaxial bearing holes on the first side surface and a second side surface opposite to the first side surface; (2) aligning a mounting surface of the auxiliary processing device and a datum hole on one side surface and fixing the auxiliary processing device; (3) aligning the gear box body and the auxiliary processing device and fixing the gear box body and the auxiliary processing device together; (4) processing a corresponding hole on the gear box body according to the datum hole on one side surface of the auxiliary processing device; and (5) repeating the operations from the step (2) to the step (4) until processing all the bearing holes on the gear box body. The invention also discloses the auxiliary processing device of the gear box body with corresponding characteristics. The invention can quickly and efficiently guarantee that the holes of the gear box body meet the requirements on the verticality, the parallelism and the position dimensional precision, improves the efficiency and reduces the cost.
Description
technical field [0001] The invention relates to the field of gearbox manufacturing, in particular to a method for processing a gearbox case and a processing auxiliary device thereof. Background technique [0002] The gearbox is a key part of the cable equipment. Its function is characterized by one-axis input and multi-axis output, and the axes of any two output shafts are in a state of being perpendicular or parallel to each other. Affected by the use environment, it is required to be small in size, compact in structure, low in noise, large in bearing capacity and high in precision. In order to meet the long-term uninterrupted continuous operation of cable equipment, the stability of the gearbox is required to be very good. [0003] This kind of gearbox is composed of nearly 100 kinds of more than 200 parts such as various gears, turbines, friction plates, bearings, shafts, positioning pins, screws, etc. As the basic carrier part of the gearbox, the box is required to hav...
