Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0020] like figure 1 , figure 2 As shown, the steering machine switch bracket processing method of the present invention comprises the following steps:

[0021] a. The shearing machine cuts the sheet into strips;

[0022] b. The strip is blanked by an 80-ton punch to form the switch bracket, and two M5 ￠4.1 threaded bottom holes are included during forming;

[0023] c. Use special tooling to clamp the switch bracket, and reverse the corners of the two sides of the ￠4.1 threaded bottom hole through a desktop drilling machine;

[0024] d. Use a 40-ton punch press to level, so that the parallel accuracy of the switch bracket is less than 0.10 mm;

[0025] e. Use a desktop drilling machine to tap two M5 ￠4.1 threaded bottom holes, deburr and clean after tapping;

[0026] f....

Abstract

The invention discloses a machining method of a steering machine switch support. The method comprises the following steps that a plate material is shorn into a strip material through a plate shearing machine; the strip material is blanked into the switch support through an 80-tonnage punch, and two M5 threaded bottom holes with the phi of 4.1 are included during forming; a special tool is used for clamping the switch support, and two faces of the threaded bottom holes with the phi of 4.1 are chamfered through a bench drilling machine; leveling is carried out through a 40-tonnage punch, and the parallel precision of the switch support is smaller than 0.10 mm; tapping of the two M5 threaded bottom holes with the phi of 4.1 is carried out through the bench drilling machine, and after tapping, burr removing and cleaning are carried out; and M5-6H precision go-no go fixed gauges are used for performing 100% detection. By means of the machining method of the steering machine switch support, the steps that blanking forming is carried out through the 80-tonnage punch, the special tool is used for performing clamping for chamfering, and the 40-tonnage punch is used for leveling are matched, and the machining method has the beneficial effects that cost is low and efficiency is high on the premise that the quality requirement is met.

Description

technical field [0001] The invention relates to a processing method for auto parts, in particular to a processing method for a steering switch bracket with low processing cost and high efficiency. Background technique [0002] With the development of the automobile industry, localization is getting faster and faster. The processing of the switch bracket on the steering column tube is an important part. The existing processing method has high cost, low processing efficiency and low processing accuracy. Contents of the invention [0003] In order to overcome the above-mentioned technical defects, the object of the present invention is to provide a method for processing the steering switch bracket with low processing cost and high efficiency. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a method for processing a steering switch bracket, comprising the following steps: [0005] a. The shearing mac...
