Example Embodiment

[0017] Example

[0018] The present embodiment discloses a hole position measuring device, which is used for measuring the deviation of the positioning holes on the subframe of the vehicle.

[0019] like figure 1 and figure 2 As shown, the device includes a base for supporting. The base includes a main body 12 and a cantilever 11. The cantilever 11 is slidably arranged on the main body 12. The cantilever 11 can be pulled out a certain distance and then fixed with the main body 12.

[0020] The cantilever 11 is provided with a cylindrical sliding portion 2 that can slide freely in the horizontal direction. A positioning column 3 that can slide up and down is inserted in the central hole of the sliding portion 2. The positioning column 3 can move downward to be inserted into the subframe At this time, since the sliding part 2 can slide arbitrarily in the horizontal direction, the sliding part 2 will have a certain offset relative to its initial position, and this offset is th...

Abstract

The invention discloses a hole site measuring device which comprises a base. The base is provided with a cylindrical sliding part, and a positioning column which can slide up and down is plugged in a center hole of the sliding part. The base is further horizontally provided with two slideable sliding pillars which are perpendicular to each other, and each sliding pillar is provided with a plane end which makes contact with the outer circumferential wall of the sliding part and is tangent to the outer circumferential wall of the sliding part. The base is further provided with springs and dial indicators. The sliding part is provided with a circular upper portion flange, the base is provided with a detachable V-shaped adjusting block, and after the V-shaped adjusting block and the upper portion flange are connected in a clamped mode, the dial indicators are in zero setting. According to the hole site measuring device, the dial indicators can be used for accurately measuring the displacement of the sliding pillars, and thus the deviation of a positioning hole can be accurately measured; an inverted cone is arranged on the lower portion of the positioning column, and the positioning column can be rapidly positioned on the measured positioning hole. The hole site measuring device is suitable for automobile-manufacturing enterprises, and positive numbers are used for measuring the deviation of the positioning hole of an auxiliary frame.

Description

technical field [0001] The invention relates to a testing tool for machined products, in particular to a tool for checking the hole position of a positioning hole of a sub-frame of a vehicle, in particular to a hole position measuring device. Background technique [0002] The location accuracy of the positioning hole on the sub-frame of the vehicle is relatively high, and its accuracy will have an impact on the driving performance of the car. In the process of processing the sub-frame, only one detection pin set on the base is used. To detect it, after positioning the sub-frame, if the detection pin can be inserted into the positioning hole when it slides down, it means that the hole is qualified. For unqualified positioning holes, this detection method cannot know the accurate deviation value of the hole position. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hole position measuring device capable of knowin...
