Detailed Description
Specific embodiments of the present utility model will be described below with reference to the accompanying drawings.
Examples
Referring to fig. 1 and 2, the present utility model discloses an irregular blind hole deep hole inspection jig, which in a preferred embodiment includes a base, a fixing unit and a measuring unit, and is used for performing nondestructive inspection on the wall thickness of the deepest part of a blind hole of a product oil rail 3. Wherein the fixing unit is used for fixing the product rail 3 on the base, and the measuring unit is positioned at one side of the fixing unit and is also fixed on the base. The distance between the fixing unit and the measuring unit matches the size of the product rail 3. For product rails 3 of different thickness, the distance between the fixing unit and the measuring unit can be adjusted on the base to fit the measuring range of the measuring unit.
In this embodiment, the base is a positioning plate 5. The positioning plates 5 are multiple, and each positioning plate 5 is also provided with a fixing unit interface and a measuring unit interface at different positions. The fixing unit interface is used for connecting the fixing unit, i.e. the fixing seat 4. The measuring unit interface is used for connecting and fixing the measuring unit, namely the supporting rod 2. For different product oil rails 3, the distance between the fixing seat 4 and the supporting rod 2 may be different, so before measurement, a suitable positioning plate 5 may be selected according to the specific size of the product oil rail, and then a fixing unit interface and a measuring unit interface at suitable positions are selected on the selected positioning plate 5, and the fixing seat 4 and the supporting rod 2 are assembled respectively, thereby meeting the measurement requirement.
The fixing unit is composed of a fixing seat 4 and a positioning rod 6. The fixing base 4 is connected to the positioning plate 5 through a fixing unit interface on the positioning plate 5. The positioning rod 6 is inserted into the fixing seat 4 and is vertically connected with the positioning plate 5. Specifically, a circular blind hole is formed in the center of the fixing seat 4, and the diameter of the circular hole is matched with the outer diameter of the positioning rod 6. The positioning rod 6 protrudes into the blind hole and is thereby fixedly connected to the holder 4. The locating rod 6 is used for extending into the product oil rail 3, and vertically fixing the product oil rail 3 on the locating plate 5. Therefore, the positioning rod 6 has various types, the outer diameter of the positioning rod needs to be matched with the inner diameter of the blind hole on the product oil rail 3, and the length of the positioning rod needs to be matched with the depth of the blind hole on the product oil rail 3, so that the product oil rail 3 can rotate around the positioning rod 6 under the condition of holding and positioning the plate 5 after being sleeved on the positioning rod 6. Similarly, because the positioning rods 6 have different diameters, the outer diameter of the circular blind hole formed in the center of the fixing seat 4 is matched with the outer diameter of the positioning rods, so that the selected positioning rods 6 matched with the product oil rail 3 can be inserted into and vertically fixed in the circular blind holes.
The measuring unit comprises a support bar 2 and a measuring instrument. In this example, the measuring instrument is a dial indicator 1. The support bar 2 is connected to the positioning plate 5 by means of a measuring cell interface on the positioning plate 5, which is perpendicular to the positioning plate 5 and parallel to the positioning bar 6 and thus also parallel to the product rail 3 which is fitted over the positioning bar 6. The dial indicator 1 is fixed on the support rod 2. Different product rails 3 are provided with blind holes of different diameters and depths, whereas the utility model is intended to measure the wall thickness at the deepest position within the blind holes. Therefore, the height of the dial indicator 1 mounted on the support rod 2 is matched with the depth of the blind hole, so that the measurement position is the deepest part of the blind hole. Similarly, although different positioning plates 5 can be selected so as to adjust the distance between the support rod 2 and the positioning rod 6, the horizontal position of the dial indicator 1 mounted on the support rod 2 can also be adjusted so as to adapt to product oil rails with different diameters in a certain interval on the premise of not replacing the positioning plates 5.
Next, a preferred embodiment of the tool for inspecting deep holes of irregular blind holes of the present utility model is specifically described, and the method for performing nondestructive wall thickness inspection on the deepest part of the blind holes of the product oil rail comprises the following steps:
step S1, a detector selects a proper positioning plate according to the diameter of a blind hole contained in a product oil rail to be detected, then selects a proper position on the positioning plate, installs a fixing seat and a supporting rod, installs a positioning rod matched with the depth of the blind hole on the fixing seat, and installs a dial indicator at a proper height of the supporting rod.
And S2, sleeving the product oil rail on the positioning rod by a detector, and adjusting the horizontal position of the dial indicator to enable the dial indicator to contact the outer wall of the product oil rail and return to zero.
And S3, the inspector rotates the product oil rail counterclockwise or clockwise for one circle, detects the wall thickness of the product oil rail through the reading of the dial indicator, and records the minimum value, namely the minimum wall thickness, in the process of rotating for one circle.
And S4, comparing a manual of the product oil rail by a detector, comparing the minimum wall thickness with a design value, and judging whether the quality of the product oil rail meets the product process requirement. The qualification part is judged in such a way that the reading of the dial indicator meets the wall thickness requirement of the process instruction. And the unqualified part is judged in such a way that the reading of the dial indicator does not meet the wall thickness requirement of the process instruction.
The method can finish nondestructive measurement, thereby enabling 100% detection of the product to be possible and improving the quality and production efficiency of the product.
The foregoing description is merely illustrative of the preferred embodiments of the present utility model, and is not intended to limit the scope of the present utility model. Equivalent changes and modifications are intended to be within the scope of the present utility model as defined in the appended claims.
