Detailed Description

The following describes the embodiments of the present invention in detail. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1, an automatic supporting and fixing device for EPB calipers comprises casters 1, a frame 2, an air source assembly 3, a lower support plate 4, a motor 5, a disc 6, EPB calipers 7, an optical axis 8, an upper support plate 9, a jacking cylinder 10, a bracket 11, a jacking compensation block 12, a guide shaft 13, a linear bearing 14, a positioning plate a 15, a positioning plate B16, a support shaft a17, a support shaft B18 and a support shaft C19; a riser 20; a tightening plate 21; supporting the positioning block 22 tightly; a slide table cylinder 23; a platen 24; a slider 25; a rail clamp 26; a guide fixing plate 27; a connecting plate 28; a lifting plate 29 and a guide rail 30.

After the motor 5 is electrified and rotates for a certain angle and the band-type brake is enabled, the air source assembly 3 is controlled to supply air to the guide rail clamp 26 to loosen the guide rail 30, so that the tightening mechanism is in a free state. The tightening mechanism is a part for tightening the EPB calipers 7 and comprises a vertical plate 20 and a tightening plate 21, and a driving mechanism matched with the part; the free state means that the slider 25 can slide freely on the guide rail 30. Meanwhile, air is supplied to the jacking cylinder 10 by controlling the air source assembly 3, the rod of the jacking cylinder 10 extends out to lift the jacking plate 29 along the direction of the guide shaft 13 through the jacking compensation block 12, so that the positioning tool is lifted to a certain height, and the support shaft A17, the support shaft B18 and the support shaft C19 support three process positioning points of the EPB caliper 7 to be horizontal; in the lifting process of the EPB caliper 7, an outer friction plate of the EPB caliper 7 touches the vertical plate 20 and enters along the chamfer angle; jacking cylinder 10 stretches out the back of targetting in place, give slip table cylinder 23 air feed through control air supply subassembly 3, slip table cylinder 23 cylinder pole stretches out and drives to prop tight locating piece 22 and move to the left side in figure 2, and then drive and prop tight board 21 and move to the inner friction disc department of EPB calliper 7, slip table cylinder 23 push rod continuously stretches out, its thrust lasts to the inner friction disc department of EPB calliper 7, receive the reaction force of its inner friction disc will prop tight mechanism and move to the outer friction disc direction of EPB calliper 7, thereby closely paste EPB calliper 7 outer friction disc department with riser 20, through the removal of propping tight board 21 and riser 20 opposite direction, and then prop tight EPB calliper 7's inner and outer friction disc. At the moment, the air source assembly 3 is controlled to supply air to the guide rail clamp 26, so that the guide rail clamp clamps the guide rail, the slide block 25 is locked, the whole tightening mechanism is fixed, and the EPB caliper 7 is fixed. After EPB calliper 7 is fixed, give slip table cylinder 23 through control air supply subassembly 3, guide rail clamp 26, jacking cylinder 10 air feed, slip table cylinder 23, guide rail clamp 26, jacking cylinder 10 returns to the primary importance, and motor 5 continues to rotate, carries out the automatic tight fixed position that props of next EPB calliper. A plurality of stations are uniformly distributed on the disc, and the embodiment only illustrates that one station supports the EPB calipers. After the mechanisms are reset, the next station of the disc rotates to the position, and the EPB calipers are automatically tightened according to the steps.

It is to be understood that although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
