However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figures 1 to 3 As shown, the present embodiment involves an outer diameter and height detection device for detecting a brake piston cylinder, comprising a detection tool 1, wherein the detection tool 1 is provided with a detection bracket 2, and the detection bracket 2 is provided with an outer diameter detection unit 3 and a height detection unit 4, and further comprising a linear reciprocating motion mechanism 5 for controlling the detection tool 1 to move in a direction close to the detection bracket 2; the linear reciprocating motion mechanism 5 is a rodless cylinder, and the linear reciprocating motion mechanism 5 comprises a mechanism assembly 501 and a slide 502, the detection tool 1 is arranged on the slide 502, and the detection bracket 2 is arranged on the mechanism assembly 501.

[0017] Furthermore, the outer diameter detection unit 3 includes an outer diameter measuring positioning seat 301, and the outer diameter measuring positioning seat 301 is provided with an outer diameter measuring positioning groove 302 with a groove opening facing forward and a groove length extending vertically up and down. The outer diameter measuring positioning seat 301 is provided with an air supply channel 303 with an air outlet opened on the groove wall of the outer diameter measuring positioning groove, and the air inlet of the air supply channel 303 is connected to an air source (not shown) through a pipeline.

[0018] Furthermore, the height detection unit 4 includes a high pressure measuring block 401, which is provided with a push rod cylinder 402 for controlling vertical up and down movement. The push rod cylinder 402 is arranged on the detection bracket 2. The high pressure measuring block 401 is provided with a height measuring rod 403 for follow-up, and the height measuring rod 403 is provided with a position sensor 404 located above the high pressure measuring block.

[0019] In this embodiment, when the workpiece is located on the detection fixture 1, the linear reciprocating motion mechanism 5 can be operated to enable its upper slide 502 to drive the detection fixture 1 and the workpiece to move until the brake piston cylinder to be measured moves into the outer diameter measurement positioning groove 302 and is located directly below the high pressure measuring block 401. The outer diameter detection unit 3 first completes the outer diameter detection of the cylinder body, and then the downward-moving high pressure measuring block 401 is combined with the position sensor 404 to complete the height detection of the cylinder body.

[0020] Among them, the outer diameter detection method is: by clamping the side of the workpiece into the outer diameter measurement positioning groove 302, since the outer wall of the workpiece is close to the air outlet, the feedback air pressure of the detection air source is compared with the feedback air pressure of the standard part. When the error is within the set range, it is qualified; when the error is outside the set range, it is unqualified (only this outer diameter measurement method belongs to the existing technology).

[0021] The utility model relates to an outer diameter and height detection device for detecting a brake piston cylinder, which integrates two detection items into one, does not require the circulation of workpieces, has high detection efficiency, complete overall functions, and strong practicality.
