Description

Technical Field

[0001] This utility model relates to the field of workpiece inspection tool technology, specifically a flatness inspection tool for the mounting plane of an air chamber support. Background Technology

[0002] air chamber support such as Figure 5 and Figure 6 As shown, the device includes a base plate and two symmetrical side plates. Both the base plate and side plates have mounting holes, which are used for installation and fixation. The three mounting surfaces are located on a plane and an inclined plane, respectively. During manufacturing, the angles of the three mounting surfaces must simultaneously meet standards; otherwise, one or two mounting surfaces will not fit properly. If forced installation is attempted, internal stress will accumulate in the air chamber support, leading to fatigue and reduced service life. Therefore, the flatness of the three mounting surfaces needs to be checked during the production of the air chamber support. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a flatness inspection tool for the mounting plane of an air chamber support, used to detect whether the flatness of the bottom plate and two side plates of the air chamber support meets the standards.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A flatness inspection tool for the mounting plane of an air chamber support includes a horizontal support base for placing the air chamber support. A column is provided on the horizontal support base at the position corresponding to the side plates on both sides of the air chamber support. A flap is movably hinged to the front of the column. A lever gauge is fixedly installed on the column above the front of the flap, and the measuring rod of the lever gauge is located in front of the flap. The two lever gauges and the two flaps are symmetrically arranged on the left and right sides.

[0006] Preferably, the horizontal support includes a central elongated support portion and flange portions disposed at the bottom of both sides of the support portion.

[0007] Preferably, the air chamber support is placed on the support portion via a base plate, and the width of the base plate is greater than the width of the support portion.

[0008] Preferably, the uprights are disposed on the flange portion, and a retainer is fixed between the two uprights.

[0009] Preferably, an extension rod is fixed to the front of the column, a hinge seat is provided on the back of the flap, and the front end of the extension rod is movably hinged to the hinge seat.

[0010] Preferably, the hinge seat is located slightly above the center of the back of the flip plate.

[0011] Preferably, a fixing rod is fixed to the upper end of the column, and the lever is fixed below the front end of the fixing rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention involves placing the air chamber bracket on the support portion of a horizontal support base, ensuring a close fit. The air chamber bracket is then pushed so that its side plates contact and press against the flip plates. The two flip plates are flipped by the pressure from the two side plates, and each flip plate pushes the measuring rod of the upper lever gauge. By checking whether the pointer of the lever gauge indicates a preset angle parameter, the flatness of the bottom plate and the two side plates of the air chamber bracket can be determined. The entire inspection tool is simple to use and convenient to operate, effectively detecting the flatness of the air chamber bracket's mounting surface. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-6As shown, this utility model provides a technical solution: a flatness inspection tool for the mounting plane of an air chamber support, including a horizontal support seat 1 for placing the air chamber support 2. The horizontal support seat 1 includes a long strip-shaped support portion 101 in the middle and flange portions 102 provided at the bottom of both sides of the support portion 101. Fixing holes are provided on the flange portions 102 to facilitate fixing it on the operating table and to facilitate quality inspection operations.

[0023] The air chamber support 2 is placed on the support part 101 via the base plate 201. The width of the base plate 201 is greater than the width of the support part 101 to accommodate the structural design that the bottom position of the side plate 202 is lower than the upper surface position of the support part 101.

[0024] A column 3 is provided on the horizontal support 1 at the position of the side plate 202 on both sides of the air chamber bracket 2. The column 3 is set on the flange part 102. A retainer 6 is fixed between the two columns 3. The entire fixture is a rigid metal structure to ensure structural stability.

[0025] The front of the column 3 is hinged to a flap 4. Specifically, the front of the column 3 is fixed with an extension rod 7, and the back of the flap 4 is provided with a hinge seat 8. The front end of the extension rod 7 is hinged to the hinge seat 8. The hinge seat 8 is located slightly above the center of the back of the flap 4, ensuring that the flap 4 hangs down naturally when not being squeezed, so that the two flaps 4 can be squeezed by the two side plates 202 respectively, and the upper end flips forward by an angle respectively.

[0026] A lever gauge 5 is fixedly installed on the column 3, located above the front of the flip plate 4, and the measuring rod 501 of the lever gauge 5 is located in front of the flip plate 4. Specifically, a fixing rod 9 is fixed at the upper end of the column 3, and the lever gauge 5 is fixed below the front end of the fixing rod 9. When the flip plate 4 flips, it will push the measuring rod 501 of the lever gauge 5, so the flip angle will be detected.

[0027] Two levers 5 and two flip plates 4 are symmetrically set on the left and right. When testing the standard part of the air chamber bracket 2, the flip angle is the standard. This angle does not need to be in degrees. This value is positively correlated with the flip angle and represents the flip range. Then, the air chamber bracket 2 under test is tested. The bottom plate 201 of the air chamber bracket 2 is placed stably on the support part 101 of the horizontal support seat 1 to ensure its levelness. Then, the levelness of the two side plates 202 is tested by the two flip plates 4, that is, whether the flip angle meets the standard.

[0028] In use, place the base plate 201 of the air chamber bracket 2 stably on the horizontal support seat 1, push the air chamber bracket 2 backward so that its two side plates 202 contact the two flip plates 4 respectively, and continue to push the air chamber bracket 2 backward. The flip plates 4 are squeezed by the side plates 202 and flip forward at the top, pushing the measuring rod 501 of the lever gauge 5. Continue to push the air chamber bracket 2 backward until it can no longer be pushed. The lever gauge 5 can then detect its flipping range. By comparing it with the standard, it can be determined whether the flatness meets the installation angle.
