Description

Technical Field

[0001] The present invention relates to the technical field of detection, and particularly relates to a lead wire thickness linear measurement device and method. Background Art

[0002] In the technical field of engine mechanical detection, lead wires are often used as extrusion objects during detection, and the required data is obtained by comparing the thickness of the lead wire before and after extrusion. However, when measuring the thickness of the lead wire, especially when measuring the linear thickness of a single lead wire, there is currently no good measurement tool. Using a traditional vernier caliper can only measure the point thickness. To obtain approximate linear data, several points are taken at equal intervals along the entire lead wire and the thickness values of these points are measured. This not only takes time and effort but also cannot truly obtain linear data, which is not conducive to providing accurate data support for subsequent related research.

[0003] The disclosure of the above background art content is only used to assist in understanding the concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background art should not be used to evaluate the novelty and inventiveness of this application. Summary of the Invention

[0004] The present invention provides a measurement device and method that can accurately and conveniently measure the linear thickness of a lead wire to solve the above technical problems.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A lead wire thickness linear measurement device, characterized in that: it includes a main body bracket, and the cross-sectional side view of the main body bracket is nearly in a rectangular shape with a loop; a slide bar is provided on the upper side inside it, and a detection slider is movably distributed on the slide bar; the detection slider includes a detection rod and an arc-shaped variable resistor; a roller is rotatably coupled to the lower end of the detection rod, and the middle lower part thereof is rotatably connected to the detection slider through a rotating shaft torsion spring assembly; a resistance slide bar is coupled to the upper part of the detection rod; the arc-shaped variable resistor is distributed corresponding to the swing area of the resistance slide bar and is in contact with the resistance slide bar; it further includes a resistance digital display module, and the resistance digital display module is connected to the resistance slide bar and the arc-shaped variable resistor.

[0007] Further, a support platform telescopic groove is formed in the lower side inside the body support; elastic support platforms are distributed in the support platform telescopic groove, and spring struts are respectively arranged at the four corners of the lower plate surface of the elastic support platform, and springs are sleeved on the spring struts; adjusting columns are respectively arranged in the middle of the left and right sides of the support platform telescopic groove, threads are arranged on the upper parts of the adjusting columns, and adjusting scales are arranged on the side surfaces thereof; adjusting column insertion holes are correspondingly formed in the left and right sides of the elastic support platform for the adjusting columns; the adjusting columns penetrate through the adjusting column insertion holes and are distributed, and pressing nuts are further distributed on the upper parts thereof, and the pressing nuts are distributed on the upper plate surface of the elastic support platform.

[0008] Further, wire clamps are arranged on the left and right sides of the elastic support platform; the wire clamps are connected with the elastic support platform through torsion spring rotating shaft assemblies.

[0009] Further, two sliding rods are provided, and return springs are respectively sleeved on the right sides thereof; the return springs are distributed on the right sides of the detection sliders; a telescopic cylinder is further arranged on the upper left side inside the body support; the telescopic rod of the telescopic cylinder is correspondingly distributed on the left side of the detection slider; the telescopic cylinder is provided with a high-pressure gas connection port and an exhaust port; a pressing valve switch is arranged in the exhaust port.

[0010] Further, the pressing nut is in a long tubular shape, and a screw port is formed at the upper end corresponding to the thread of the adjusting column.

[0011] A method for measurement using a wire thickness linear measurement device as described above includes the following steps:

[0012] (1) Place the wire to be measured on the elastic support platform, flatten it on the upper plate surface of the elastic support platform, and clamp both ends through the wire clamps.

[0013] (2) For the type of the wire to be measured, adjust the pressing nut on the adjusting column to the corresponding standard scale value, that is, check through the adjusting scale to make the elastic support platform in a standard high position and elastic support strength. At this time, the roller of the detection rod is in close contact with the wire.

[0014] (3) Then start the wire thickness linear measurement device, the telescopic cylinder intakes air, and pushes the detection slider to move to the right. When repeating the test, only need to stop intake air and open the pressing valve switch to exhaust air. Then, under the action of the return spring, the detection slider moves to the left to realize re-measurement; read out the changed value through the resistance digital display module, record the lowest measurement value, and obtain the required thickness measurement value by proportionally converting the measurement value into a wire thickness value.

[0015] The beneficial effects of the present invention compared with the prior art:

[0016] By adopting the translation detection method with a detection slider, the linear thickness of the entire lead wire is measured; at the same time, by combining with rollers that roll into contact with the lead wire, it effectively prevents measurement errors caused by lead wire wear. By combining with an adjustable elastic support platform, it not only realizes the general measurement of lead wires of various models, but also, during the measurement process, for example, when the middle of the lead wire is less squeezed (i.e., protruding compared to both sides), at this time, the detection slider pushed pneumatically and evenly will be subjected to greater force at this point. If there is no such elastic support platform, it is easy to have the rollers pressing the lead wire too much, resulting in the lead wire being flattened at this point, leading to the lead wire being "stretched" or being squeezed and stacked into the adjacent area, causing the linear length and thickness of the entire lead wire to be out of sync / biased, and it is also easy to cause the lead wires on both sides of the protruding part to be forced to warp and not fit the upper plate surface of the elastic support platform, which will also cause inaccurate detection data in other areas. This is also a prominent problem that occurs when realizing the linear measurement of lead wires. By providing this elastic support platform, under the condition of maintaining the standard roller pressure during the measurement of lead wires of the same model, when encountering a more protruding lead wire segment, it can sink elastically through the elastic support platform, thus solving the above problems. After the elastic support platform elastically sinks for the protruding part of the lead wire, the detected value at this point will be smaller than the actual value. However, what the present invention needs to detect is the minimum value of the entire measurement lead wire in the interference amount detection test. Therefore, this problem will not cause any interference to the detection structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 is a sectional side view of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0018] As Figure 1 shown, the present invention is mainly a lead wire thickness linear measurement device specially developed for the test lead wire of the interference amount of the cylinder head. The detection of the lead wire thickness by this lead wire thickness linear measurement device is mainly applicable to the measurement of the linear thickness of the lead wire. The lead wire thickness linear measurement device includes a body bracket 1, and the sectional side view of the body bracket 1 is nearly in a rectangular shape; there are two slide bars 2 provided on the upper side inside it, and a detection slider 3 is movably distributed on the slide bars 2, that is, it is sleeved on the slide bars 2 and movably distributed by opening two chute 3-1s; a return spring 4 is also provided on the slide bars 2; the return spring 4 is distributed on the right side of the detection slider 3; an expansion cylinder 5 is also provided on the upper left side inside the body bracket 1; the expansion rod of the expansion cylinder 5 is correspondingly distributed on the left side of the detection slider 3; the expansion cylinder 5 is provided with a high-pressure gas connection port and an exhaust port; a pressing valve switch is provided in the exhaust port. During use, the expansion of the expansion rod of the expansion cylinder 5 is realized by high air pressure, and by opening the pressing valve switch, exhaust is realized and the return sliding of the detection slider 3 is realized through the return spring 4.

[0019] The detection slider 3 includes a detection rod 7 and an arc-shaped variable resistor 6; a roller 9 is rotatably coupled to the lower end of the detection rod 7, and the middle-lower part thereof is rotatably connected to the detection slider 3 through a rotating shaft torsion spring assembly 8, that is, the detection rod 7 swings in a lever manner (the upper part is longer than the lower part to improve the detection accuracy); a resistance slider 7-1 is coupled to the upper part of the detection rod 7; the arc-shaped variable resistor 6 is distributed corresponding to the swinging area of the resistance slider 7-1 and contacts the resistance slider; a resistance digital display module is further included, and the resistance digital display module is connected to the resistance slider and the arc-shaped variable resistor, that is, a circuit is formed. When the resistance slider 7-1 swings upward, the resistance value becomes smaller, and when it swings downward, the resistance value becomes larger. Through the screening and adjustment of the resistance, the equal-proportion conversion between the resistance value and the thickness value can be realized, mainly for facilitating subsequent calculations. A support platform telescopic groove 1-1 is provided on the inner lower side of the body bracket 1; elastic support platforms 10 are distributed in the support platform telescopic groove. Spring struts 14 are provided at the four corners of the lower plate surface of the elastic support platform 10, and springs 15 are sleeved on the spring struts 14; adjusting columns 13 are further provided in the middle of the left and right sides of the support platform telescopic groove. Threads 13-1 are provided on the upper part of the adjusting column 13, and adjusting scales are provided on the side surface thereof for precise adjustment; adjusting column insertion holes 10-1 are provided on the left and right sides of the elastic support platform corresponding to the adjusting columns; the adjusting columns pass through the adjusting column insertion holes and are distributed, and pressing nuts 16 are further distributed on the upper part thereof. The pressing nuts 16 are in the shape of long tubular cylinders, and screw openings are provided at the upper ends corresponding to the threads of the adjusting columns to prevent the adjusting column insertion holes 10-1 from contacting the threads 13-1 of the adjusting columns, and the threads will increase the frictional force on the inner cavity of the adjusting column insertion holes 10-1, which is not conducive to improving the up-and-down telescopic performance of the elastic support platform 10. In fact, lubricant needs to be applied at this place during use. The pressing nuts 16 are distributed on the upper plate surface of the elastic support platform. Of course, for the convenience of fixing, wire clamps 11 are provided on the left and right sides of the elastic support platform 10; the wire clamps 11 are connected to the elastic support platform through a torsion spring rotating shaft assembly 12.

[0020] When measuring the linear thickness of the wire using the wire thickness linear measuring device, the operation steps are as follows:

[0021] (1) Place the wire to be measured on the elastic support platform, flatten it on the upper plate surface of the elastic support platform, and clamp both ends through the wire clamps;

[0022] (2) For the type of the wire to be measured, adjust the pressing nut on the adjusting column to the corresponding standard scale value, that is, check through the adjusting scale to make the elastic support platform in a standard high position and elastic support strength. At this time, the roller of the detection rod is in close contact with the wire;

[0023] (3) Then start the lead wire thickness linear measurement device. The telescopic cylinder intakes air and pushes the detection slider to move to the right. When repeating the test, just stop intaking air and open the pressing valve switch to release air. Then, under the action of the return spring, the detection slider moves to the left to achieve re-measurement. Read the changed value through the resistance digital display module and record the lowest measurement value. Obtain the required thickness measurement value by proportionally converting the measurement value into the lead wire thickness value.
