Problems solved by technology
The four mounting holes connecting the sub-frame and the body are mainly located on the left and right longitudinal beams. The outer wall of the hole is a casting surface, and the inner wall is a machined surface. Due to casting deformation and welding deviation, there are often walls in the mounting holes of the body after machining. Thickness deviation, that is, when looking down from the front of the body mounting hole, the wall thickness is uneven, and there are wide and narrow sides on the upper surface of the body mounting hole. If the caliper is used to measure, not only the efficiency is low, but also only part of the cross-section measurement can be taken, and a circle cannot be realized. continuous measurement

Embodiment Construction
[0011] The details and working conditions of the specific device proposed by the present invention will be given below in conjunction with the description of the accompanying drawings.
[0012] A checking device for detecting the wall thickness of the mounting hole of a sub-frame body, including a handle frame 1, a sleeve 2, a circular guide rail 3, a rotating ring 4, a spring 5, a sliding ring 6, a lower difference detection ring 7, an electric cylinder 8, and an upper difference Detect ring 9, expansion sleeve 10 and expansion core 11. The handle frame 1 is installed on the upper surface of the sleeve 2, which is used for the detection of the hand-held inspection tool. The outer wall of the sleeve 2 is fixedly installed with an annular guide rail 3. The sliding ring 6 is enclosed within the outer wall of the sleeve 2, and the sliding ring 6 can slide up and down along the outer wall of the sleeve 2, and can also freely rotate around the outer wall of the sleeve 2. The diamet...

A detection tool for detecting the wall thickness of an auxiliary frame vehicle body mounting hole is composed of a handle frame, a sleeve, an annular guide rail, a rotating ring, a spring, a slidingring, a lower difference detection ring, an electric cylinder, an upper difference detection ring, an expansion sleeve and an expansion core. The invention has the advantages that: (1) a lightweight design is adopted, so that the detection is convenient, quick, efficient, practical, simple in structure and ingenious in design; (2) the expansion sleeve is adopted for positioning, the positioning precision is high, and the detection precision is high; and (3) whether the thickness of the annular circumferential wall of the auxiliary frame vehicle body mounting hole is out of tolerance or not canbe quickly and continuously measured, and discontinuity and inaccuracy of caliper sampling detection are avoided.
Description
technical field [0001] The invention relates to the technical field of detection after machining of a sub-frame, in particular to a checker for detecting the wall thickness of a mounting hole of a sub-frame body. Background technique [0002] At present, steel subframes are being replaced by aluminum subframes. The more popular subframes are made of aluminum castings and aluminum profiles. This subframe is mainly composed of left longitudinal beams, right longitudinal beams, and front beams. It is composed of the rear beam and the left longitudinal beam and the right longitudinal beam are aluminum castings, and the front beam and the rear beam are aluminum profiles. The four mounting holes connecting the subframe and the body are mainly located on the left and right longitudinal beams. The outer wall of the hole is a casting surface, and the inner wall is a machined surface. Due to casting deformation and welding deviation, there are often wall holes in the mounting holes of...
