Description

Technical Field

[0001] This utility model relates to the field of workpiece quality inspection technology, and specifically to a device for measuring the surface flatness of titanium strip coils in plate heat exchangers. Background Technology

[0002] In the field of nuclear power plate heat exchangers, titanium metal has been widely used due to its excellent corrosion resistance, radiation resistance, and high thermal conductivity. However, plate heat exchangers have extremely high requirements for the comprehensive mechanical properties and appearance of the titanium substrate, especially regarding the flatness of the titanium plate. Typically, the overall flatness of the substrate is required to be less than 5 mm / m; otherwise, poor plate shape may obstruct fluid flow during use, thus affecting heat exchange efficiency. Therefore, the flatness inspection of coils and plates is extremely important in the preparation and inspection of pure titanium substrates. Flatness inspection of coils can optimize the rolling process and further improve the plate shape, while flatness inspection of finished plates is a standard that determines whether the plate meets the acceptance criteria.

[0003] Currently, a combination of straightedge and feeler gauge is commonly used to inspect unevenness. This requires two types of tools, and the measurement error can be large due to issues with the verticality and tightness of the feeler gauge. Furthermore, since feeler gauges are usually made of steel, their hardness is higher than that of titanium, which may cause damage to the surface of the titanium plate (coil) and have a significant impact on the surface quality of the titanium plate.

[0029] Example:

[0030] See Figure 1 As shown, the present invention provides a plate heat exchanger titanium strip coil surface flatness measuring device, which includes a horizontal ruler 1 and a measuring ruler 2.

[0031] The horizontal ruler 1 includes a ruler body and a horizontal guide rail 101 disposed on one side of the ruler body;

[0032] The measuring ruler 2 is provided at least one, and at least one measuring ruler 2 is movably connected to the horizontal guide rail 101 so that, according to the measurement needs, at least one measuring ruler 2 can be used simultaneously to measure the surface position at different positions on the surface of the titanium strip coil, obtain the data corresponding to the number of measurement points, and thus obtain the unevenness value of the entire surface of the titanium strip coil.

[0033] Preferred, see Figure 2 As shown, the measuring ruler 2 includes a measuring pen 201, a scale panel 202, a measuring mark 203, and a limiting ring 204;

[0034] One end face of the scale panel 202 is provided with a measuring scale line in the vertical direction, and the other end face of the scale panel 202, which is parallel to the measuring scale line, is provided with a connecting part that cooperates with and can be slidably connected to the horizontal guide rail 101.

[0035] The measuring pen 201 is movably disposed on the end face of the scale panel 202 where the measuring scale lines are provided, and the measuring pen 201 is displaced along the distribution direction of the measuring scale lines;

[0036] The measuring mark 203 is fixedly mounted on the measuring pen 201, and in the initial position, the position of the measuring mark 203 is aligned with the 0-degree position of the measuring scale line;

[0037] The limiting ring 204 is disposed on the end face of the scale panel 202 where the measuring scale lines are provided, and is used to limit the range of motion of the measuring pen 201 to prevent the measuring pen 201 from leaving the scale panel 202.

[0038] In a further preferred embodiment, a fine-tuning structure for vertical adjustment is provided between the limiting ring 204 and the scale panel 202. When the tip of the measuring pen 201 wears down, by adjusting the relative position of the limiting ring 204 with respect to the scale panel 202, the tip of the measuring pen 201 is always aligned with the horizontal line below the horizontal ruler when it is zeroed.

[0039] Further preferably, a vertical guide structure is provided between the measuring pen 201 and the scale panel 202, and the vertical guide structure is preferably a guide rail slider structure. Specifically, a slider is mounted on the measuring pen 201, and a guide rail that matches the slider is mounted on the scale panel 202. Even more preferably, a limiting structure is provided on the guide rail slider structure, and the limiting structure is used to prevent the measuring pen from falling downwards due to gravity. Specifically, the specific form of the limiting structure refers to the prior art.

[0040] Further preferably, to avoid damage to the surface of the titanium strip roll caused by the pen tip of the measuring pen 201 during measurement, the pen tip of the measuring pen 201 is designed with a rounded tip structure. Specifically, see... Figure 3 As shown, the pen tip of the measuring pen 201 includes a first arc segment, a second arc segment, and a planar contact segment. The first arc segment and the second arc segment are symmetrically arranged along the vertical central axis of the measuring pen 201, and the first arc segment and the second arc segment intersect and transition with each other and are both connected to the planar contact segment. The end face of the planar contact segment that is used to contact the surface of the titanium strip is set as a planar structure.

[0041] Further preferably, to avoid damage to the surface of the titanium strip roll caused by the pen tip of the measuring pen 201 during measurement, the pen tip of the measuring pen 201 may also be configured as a structural component made of a plastic material or a material with a hardness lower than that of titanium metal (such as aluminum alloy).

[0042] As a further embodiment of this utility model, the specific process of using the above-described measuring device to detect the unevenness of the titanium strip coil surface is as follows:

[0043] S1. Before use, zero the level on a horizontal surface. Move the measuring pen to its highest position so that the limit ring contacts the top of the measuring scale panel, the pen tip is on the same horizontal line as the bottom of the level, and the measuring mark is aligned with the 0 mark on the measuring scale panel. If it is not zeroed, the position of the limit ring or the measuring mark needs to be fine-tuned. By setting the zeroing step, you can ensure that the pen tip is on the same horizontal line as the bottom of the level and that the measuring mark is in the zeroed state.

[0044] S2. When using, place the horizontal ruler above the surface of the titanium strip roll to be tested, move the measuring ruler to the concave part of the surface of the titanium strip roll to be tested, move the measuring pen so that the pen tip contacts the top of the surface of the titanium strip roll to be tested, and read the value on the measuring panel to measure the flatness value of the surface of the titanium strip roll to be tested. The flatness condition of the surface of the titanium strip roll to be tested is determined based on the flatness value obtained from multiple measurements.

[0045] S3. After the measurement is completed, move the measuring pen to the top to complete the zeroing.

[0046] Further, see Figure 4 As shown, if necessary, multiple measuring devices can be installed to measure the unevenness at multiple locations simultaneously.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
