Description
Technical Field
The utility model belongs to a detection means of machine parts processing trade specifically is an utensil is examined to hole bottom chamfer hole degree of depth.
Background
In the current machining industry, a group of holes machined by some products consists of 2 holes with different sizes, an upper large hole and a lower small hole are formed by chamfering formed by tool transition, drawing requirements have strict requirements on the depth of the upper large hole, but the detection is usually inaccurate by using conventional measuring tools such as calipers and the like, the measured part is easy to slide on the inclined plane of the chamfered part, the measured false appearance is caused, the consistency of repeated measurement is poor, and troubles are caused for ensuring the production quality.
Disclosure of Invention
The utility model aims at providing an easy operation, convenient and practical's hole bottom chamfer hole degree of depth examines utensil can the rapid survey wait to detect the degree of depth of the big terminal surface of work piece hole chamfer.
The technical solution of the utility model is that: comprises a cylindrical fixed gauge and a movable gauge; the movable gauge comprises an upper section part positioned in the inner cavity of the fixed gauge and a lower section part extending into the hole of the workpiece to be detected, and the lower section part is positioned outside the inner cavity of the fixed gauge; the side wall of the upper section of the movable gauge is provided with a limiting hole for limiting the movable stroke of the movable gauge, the side wall of the fixed gauge is provided with a set screw corresponding to the limiting hole, and the end part of the set screw extends into the limiting hole; the lower end face of the lower section of the movable gauge is a plane which is the same as the large end face of the chamfer of the workpiece hole to be detected; the upper surface of the fixed gauge is a step surface, the step surface comprises a fixed gauge upper step and a fixed gauge lower step, and the height difference between the fixed gauge upper step and the fixed gauge lower step is equal to the tolerance value of the depth of the large end surface of the hole chamfer of the workpiece to be detected; the moving stroke of the movable gauge is larger than the height difference between the high plane part and the low plane part. The moving stroke of the movable gauge is larger than the height difference between the high plane part and the low plane part, otherwise, the product is unqualified and is judged to be qualified.
And the lower end face of the fixed gauge is a lower plane of the fixed gauge matched with the end face of the hole of the workpiece to be detected.
The fixed gauge is cylindrical, and the movable gauge is cylindrical.
The workpiece hole to be detected comprises an upper section inner hole section, a lower section inner hole section and a hole chamfer positioned between the upper section inner hole section and the lower section inner hole section, wherein the inner diameter of the upper section inner hole section is larger than that of the lower section inner hole section; the outer diameter of the upper section of the movable gauge is equal to the inner diameter of the fixed gauge, and the outer diameter of the lower section of the movable gauge is equal to the inner diameter of the inner hole section of the upper section on the large end face of the hole chamfer of the workpiece to be detected.
Compared with the prior art, the utility model has the characteristics of convenient operation, simple structure, precision are reliable, it is easy to make, with low costs, easily production etc. The utility model discloses the product that can solve spot processing fast detects the degree of difficulty big, guarantees that the product is qualified, satisfies the problem that client required.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure, 1, a set screw, 2, a movable gauge, 3, a fixed gauge, 4, a workpiece to be detected, 5, an upper step of the fixed gauge, 6, an upper plane of the movable gauge, 7, a lower step of the fixed gauge, 8, a limiting hole, 9, a lower plane of the fixed gauge, and 10, a lower plane of the movable gauge.
Detailed Description
In fig. 1, activity rule 2 is through in the fixed rule 3 of holding screw 1, it can guarantee that activity rule 2 has certain upper and lower slip volume in fixed rule 3 to be equipped with spacing hole 8 on the activity rule 2 through 1 wrong income spacing hole 8 of holding screw, fixed rule 3 is by fixed rule upper step 5, fixed rule lower step 7 and fixed rule lower plane 9 are constituteed, the difference in height of fixed rule upper and lower step is according to being detected work piece hole tolerance design, activity rule lower plane 10 does not allow the chamfer to make activity rule 3 just can place on the root of being detected work piece hole chamfer, can not slide to go on the inclined plane of chamfer.
When the movable gauge is used, the movable gauge 2 is placed in a hole of a workpiece to be detected, the lower plane 9 of the fixed gauge is tightly attached to the workpiece to be detected, then the movable gauge 2 is pressed down to ensure that the movable gauge is matched with the root of the chamfer of the hole of the workpiece to be detected, and whether the upper plane 6 of the movable gauge is between the lower step 7 of the fixed gauge and the upper step 5 of the fixed gauge is observed, if the movable gauge is lower than the lower step 7 of the fixed gauge or higher than the upper step 5 of the fixed gauge, the product is unqualified. The method can be observed by eyes or touched by hands.
