Problems solved by technology

The original drilling process is completed in three times, and three sets of drilling molds are used to ensure that it must be clamped three times, which can be completed on three drilling machines, and the weight of the wheel hub is usually about 50Kg, which is not only inefficient and labor-intensive. High strength, but also affect the increase in production capacity

Embodiment Construction

[0027] see Figure 2-Figure 11 , the heavy-duty axle hub drilling fixture mainly consists of a main body 1, a rotating body 4, a rotating shaft 6, a compression screw 3, a positioning ring 9, a positioning pin 11, a drilling template 15, a b drilling template 12, a hook-shaped pressing plate 18, Locator 19 etc. are formed.

[0028] see figure 2 , The revolving body 4 is a U-shaped frame body, its two sides and the body 1 are connected through the rotating shaft 6 and the adjusting washer, and the gap between the two is adjusted with the adjusting washer 7 to ensure that the revolving body 4 rotates flexibly around the rotating shaft 6. First screw 5 is housed beside rotating shaft 6, is pressed on rotating shaft 6 limits, prevents rotating shaft 6 from deviating from. On one side of the revolving body 4, with the revolving shaft 6 as the center, there are x positioning holes and y positioning holes on the circumferences of the radii R1 and R2, the radius R1 is 180mm, and th...

Abstract

The invention relates to a fixture for drilling inflating and discharging holes in a hub, which comprises a body, a revolution body, a rotating shaft, housing screws, a locating ring, a locating pin, a drilling template, a b-type drilling template, a hook clamp plate and a localizer. The revolution body is a U-shaped frame body, and both sides of the revolution body are connected with the body through the rotating shaft and an adjusting washer. The housing screws are symmetrically arranged on both sides of the body with three screws on each side, wherein two screws in each side are distributed in a horizontal position and the third screw is vertical to the horizontal plane. By adopting a rotation design, three working procedures are merged into one working procedure, and three holes are processed with a set of fixture and a drilling machine, thus reducing fixturing frequency, saving time and labor, and improving labor efficiency.

Description

technical field [0001] The invention relates to a heavy-duty axle hub processing fixture with an inflation and deflation system, which is mainly used for processing the inflation and deflation holes of the hub. Background technique [0002] The heavy-duty axle hub with inflation and deflation system has three inflation and deflation holes a, b, and c. These three holes are located on different planes of the hub, see figure 1 . The original drilling process is completed in three times, and three sets of drilling molds are used to ensure that it must be clamped three times, which can be completed on three drilling machines, and the weight of the wheel hub is usually about 50Kg, which is not only inefficient and labor-intensive. The strength is high, and it also affects the increase in production capacity. Contents of the invention [0003] The purpose of the present invention is to avoid the disadvantages of the above-mentioned prior art, and to provide a clamp for drillin...
