Problems solved by technology

Using the outer eight-hole pneumatic measuring instrument for measurement, the cost of the inspection tool is high, the measurement time is long, the measurement variation is large, the measurement is unstable, the operation is inconvenient, the skill level of the operator is relatively high, and the efficiency is relatively low; When measuring with a micrometer, the measuring force of the micrometer anvil is relatively large, and the wall thickness of the part is thin. During the measurement, the micrometer anvil will squeeze and deform the outer circle of the part, which will affect t

Example Embodiment

[0010] Example: as figure 1 As shown in the figure, a measuring tool for the height difference between the outer circular bosses of thin-walled rotary parts includes a base plate 1, and two upright columns 2 are arranged on the base plate 1, and a cross bar parallel to the base plate 1 is arranged between the upper ends of the two upright columns 2 3. There is a fixed bracket 4 on the cross bar 3, a dial indicator 5 is connected under the fixed bracket 4, and the bottom plate 1 under the dial indicator 5 is provided with two identical parts 8 along the direction of the horizontal bar 3. V-blocks 6, 7. Between the bottom plate 1 and the column 2, between the column 2 and the cross bar 3, between the cross bar 3 and the fixed bracket 4, and between the fixed bracket 4 and the dial indicator 5 are all fixed by bolts. The V-shaped blocks 6 and 7 are provided with wear-resistant hard blocks 9 at the positions in contact with the parts 8, and the wear-resistant hard blocks 9 have h...

Abstract

An inspection device for an excircle boss height difference of a thin-wall rotation-type part comprises a base plate. Two stand columns are arranged on the base plate, a transverse rod parallel to the base plate is arranged between upper ends of the two stand columns, a fixing support is arranged on the transverse rod, a dial indicator is connected with the position below the fixing support, and two same V-shaped blocks for placing parts are arranged on the base plate below the dial indicator along the direction of the transverse rod. The base plate and the stand columns are fixed through a bolt, the stand columns and the transverse rod are fixed through a bolt, the transverse rod and the fixing support are fixed through a bolt, and the fixing support and the dial indicator are fixed through a bolt. Wear-resisting hard blocks are arranged on positions of the V-shaped blocks contacted with the parts. The inspection device is convenient, rapid and efficient in detection process, greatly improves detection efficiency, greatly reduces labor intensity and operation difficulty of workers and simultaneously is high in detection accuracy.

Description

technical field [0001] The invention relates to a measuring tool for the height difference of an outer circular boss of a thin-walled rotary part. Background technique [0002] For the measurement of the height difference of the outer cylindrical boss of thin-walled rotary parts, most of them are measured by the outer eight-hole pneumatic measuring instrument and the outer diameter micrometer. Using the outer eight-hole pneumatic measuring instrument for measurement, the cost of the inspection tool is high, the measurement time is long, the measurement variation is large, the measurement is unstable, the operation is inconvenient, the skill level of the operator is relatively high, and the efficiency is relatively low; When measuring with a micrometer, the measuring force of the micrometer anvil is large, and the wall thickness of the part is thin. During the measurement, the micrometer anvil will squeeze and deform the outer circle of the part, which will affect the measure...
