Detailed Description

For making the purpose, technical solution and advantages of the present invention clearer, it will be right below that the technical solution of the present invention is clearly and completely described, based on the specific embodiments of the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work belong to the scope protected by the present invention.

Fig. 1 is a schematic structural diagram of a conventional cylinder body 1, pin holes 3 are formed in two sides of a top 11 of the cylinder body, a step surface 2 is formed in the front of the cylinder body 1, and a vertical distance between the step surface 2 and a connecting line of the two pin holes 3 is referred to as a height of the step surface 2. The actual height of the step surface 2 of the cylinder body 1 actually produced is often deviated from the designed height of the step surface 2 to a certain extent, and when the actual height of the step surface 2 is between the minimum designed height of the step surface 2 and the maximum designed height of the step surface 2 allowed in the design, the step surface 2 is considered to be qualified.

As shown in fig. 2, the utility model provides a cylinder body oil duct is sealed examines utensil (hereinafter abbreviated as examine utensil), including panel 5, panel 5 has top surface and bottom surface, sets up two locating holes 7 that run through panel top surface and panel bottom surface on the panel 5, and locating hole 7 is arranged the position and is corresponding with the distribution position of the pinhole 3 that awaits measuring cylinder body top 11, can fix examining utensil 4 on the cylinder body 1 that awaits measuring through the locating pin. The border of panel 5 is provided with the detection portion 6, is provided with one on the detection portion 6 and detects step 8, detects step 8 and is used for contrasting with the step face 2 on the cylinder body 1 that awaits measuring to whether quick accurate judgement work piece meets the standard requirement, has saved check-out time, has improved the efficiency of judging. The number and the arrangement position of the detection parts 6 correspond to the number and the distribution position of the step surfaces 2 on the cylinder body 1 to be detected, and three detection parts 6 are correspondingly arranged by taking the cylinder body in fig. 1 as the cylinder body 1 to be detected.

As shown in fig. 3, the detection step 8 is a single-step, and includes a lower step surface 81 and an upper step surface 82. The vertical distance between the lower stepped surface 81 and the connecting line of the two positioning holes 7 is called as the height H1 of the lower stepped surface, and the height H1 of the lower stepped surface is equal to the minimum design height of the stepped surface 2 of the corresponding stepped surface 2; the vertical distance between the upper stepped surface 82 and the connecting line of the two positioning holes 7 is called as the height H2 of the upper stepped surface, and the height H2 of the upper stepped surface is equal to the maximum design height of the stepped surface 2 of the corresponding stepped surface 2; the height H1 of the upper step surface 82 and the lower step surface is different from the height of the step, i.e. the height of the step corresponds to the maximum tolerance allowed by the step surface 2.

In a preferred scheme, the detection part 6 is level with the bottom surface of the panel, so that the detection tool 4 can be attached to the top surface of the cylinder body 1, and the detection step 8 is convenient to compare with the step surface 2 on the cylinder body 1 to be detected. More preferably, panel 5 and detection step 8 integrated into one piece, the top surface of detection portion 6 and panel bottom surface and panel 5 is equal to be flat, reduces and connects the section, makes examine a 4 whole more level and smooth just, changes in the laminating of the top surface with the cylinder body 1 that awaits measuring, and is difficult for the compression fracture.

In a preferred embodiment, the panel 5 has a rectangular plate-like structure, and the corner of the panel 5 on the side close to the detection part 6 is provided with an arc-shaped chamfer 51, so that the dimension error caused by edge burrs is avoided.

In order to operate the checking fixture 4 conveniently, a handle can be further arranged and arranged on the top surface of the panel.

In order to make the checking fixture 4 wear-resistant and not easy to deform, the preferable checking fixture 4 is made of stainless steel materials.

In the present invention, the detecting unit 6 may be designed to protrude from the side edge of the panel 5 (as shown in fig. 2), or may be designed to be substantially flush with the edge of the panel 5 (as shown in fig. 4).

Referring to fig. 5, when the checking fixture 4 in fig. 2 is used for performing sealing detection on the oil duct seal of the cylinder body 1, the checking fixture 4 is placed on the top surface of the cylinder body 1, the positioning hole 7 is aligned with the pin hole 3, the checking fixture 4 is connected with the cylinder body 1 through the positioning pin, three step surfaces 2 on the cylinder body 1 are respectively compared with three corresponding detection steps 8 on the checking fixture 4 through visual observation or manual touch, and when the step surfaces 2 are located between an upper step surface 82 and a lower step surface 81, the step surfaces 2 are judged to be qualified; when all the step surfaces 2 of the cylinder body 1 are judged to be qualified, judging that the oil duct sealing detection of the cylinder body 1 is qualified; and when the cylinder body 1 has a step surface 2, judging that the oil duct sealing detection of the cylinder body 1 is unqualified.

The stage number of the detection step 8 can be set according to the detection requirement, and when only the step surface 2 is qualified or not, a single-stage step can be used for comparison judgment; if the grade of a qualified product needs to be further refined, the detection step 8 can be set as a multi-stage step, and the product grade of the qualified product is judged according to the position of the step surface 2 relative to the multi-stage step.

Finally, it should be noted that: the above embodiments and examples are only used to illustrate the technical solution of the present invention, but not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments and examples, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments or examples may still be modified, or some of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments or examples of the present invention.
