Description

Technical Field

[0001] The utility model relates to a test tooling, in particular to a resistance strip resistance measurement tooling. Background Art

[0002] When testing the resistance strip in an instrument, one end of the resistance strip is connected to a multimeter through a flexible cable. The resistance strip is placed at the test tooling, and it is pressed down at intervals along its shape. By observing the value displayed on the multimeter, it is judged whether the resistance strip is qualified.

[0003] For the resistance strip of a 49-key piano, it has a linear structure. For the resistance strip of a cymbal plate, it has an annular structure. Two different test toolings are needed to test the linear-structured resistance strip and the annular-structured resistance strip.

[0004] In summary, how to use one test tooling to detect the linear-structured resistance strip and the annular-structured resistance strip has become an urgent problem for researchers in the field to solve. Summary of the Invention

[0005] The technical problem to be solved by the utility model is: how to use one test tooling to detect the linear-structured resistance strip and the annular-structured resistance strip.

[0006] To solve the above technical problem, the technical solution adopted by the utility model is:

[0007] The utility model is a resistance strip resistance measurement tooling, including: a base; a vertical seat fixedly connected to the base; a downward pressing test part slidably connected to the vertical seat through a pneumatic linear guide; a detection straight groove opened on the upper surface of the base and adapted to place a linear resistance strip; a circular groove opened on the upper surface of the base, and the center of the circle is located on the center line of the detection straight groove; wherein, the circular groove is directly below the downward pressing end of the downward pressing test part.

[0008] In this solution, the linear-structured resistance strip is placed in the detection straight groove. The pneumatic linear guide is started to make the downward pressing test part move downward, and the downward pressing end presses the linear-structured resistance strip. After the detection is completed, the downward pressing end moves upward to detect the next position of the resistance strip, realizing the resistance detection of the linear-structured resistance strip.

[0009] The reason for setting the circular groove is that the diameter of the downward pressing end is greater than the width of the resistance strip, so that the downward pressing end can cover the width of the resistance strip, and the detection is more comprehensive, and the downward pressing end can avoid interfering with the detection straight groove.

[0010] To achieve the testing of the arc-shaped structural resistance strip, the present utility model adopts a test bench, which is arranged in the detection straight groove, and its upper surface is flush with the upper surface of the base; a test positioning part, the test positioning part is convexly arranged on the inner and outer sides of the test bench, and the test positioning part matches the circular groove; an arc-shaped protrusion, which is convexly arranged on the upper surface of the test bench, and its inner side is adapted to abut against the outer side of the arc-shaped resistance strip;

[0011] When it is necessary to test the arc-shaped structural resistance strip, the test bench is installed in the detection straight groove. The detection straight grooves on both sides of the detection straight groove match the circular groove to prevent the test bench from moving in the detection straight groove. The arc-shaped protrusion is arranged on the upper surface of the test bench and can fit the arc-shaped resistance strip to play a positioning role for the arc-shaped resistance strip. The pressing test part descends, and the pressing end presses on the arc-shaped resistance strip. After the detection is completed, the pressing end ascends, rotates the resistance strip, and detects the next position to realize the resistance detection of the arc-shaped resistance strip.

[0012] To more accurately test the resistance performance of the arc-shaped resistance strip, the present utility model adopts that an avoidance notch is opened on the arc-shaped protrusion; when the pressing end of the pressing test part presses down, a part of the pressing end is located at the avoidance notch;

[0013] By setting the avoidance notch, after the pressing end descends, the pressing end does not interfere with the arc-shaped protrusion, and the pressing end can completely cover the width of the resistance strip, so as to more accurately test the resistance performance of the arc-shaped resistance strip.

[0014] The beneficial effects of the present utility model: The present utility model is a resistance strip resistance testing tooling. The straight detection straight groove in this solution can realize the detection of the straight resistance strip, and by adding a test bench, the detection of the arc-shaped resistance strip can be realized. In summary, the resistance performance detection of the straight-structured resistance strip and the circular-structured resistance strip is realized. Brief Description of the Drawings

Detailed implementation mode

[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] As Figure 1 、 3 shown, the present utility model is a resistance strip resistance measurement tooling, including: a base 1; a vertical base 2, which is fixedly connected to the base 1; a downward pressure testing part 3, which is slidably connected to the vertical base 2 through a pneumatic linear guide 4; a detection straight groove 5, which is opened on the upper surface of the base 1 and is adapted to place a straight resistance strip; a circular groove 6, which is opened on the upper surface of the base 1 and its center is located on the center line of the detection straight groove 5; wherein, the circular groove 6 is directly below the downward pressure end 7 of the downward pressure testing part 3;

[0023] In this solution, the resistance strip with a linear structure is placed in the detection straight groove. The pneumatic linear guide is started to make the downward pressure testing part move downward, and the downward pressure end applies pressure to the resistance strip with a linear structure. After the detection is completed, the downward pressure end moves upward to detect the next position of the resistance strip, realizing the resistance detection of the resistance strip with a linear structure;

[0024] The reason for setting the circular groove is that the diameter of the downward pressure end is larger than the width of the resistance strip, so that the downward pressure end can cover the width of the resistance strip, and the detection is more comprehensive, and in this way, the downward pressure end can avoid interfering with the detection straight groove.

[0025] As Figure 2 、 4 shown, in order to realize the test of the resistance strip with an arc-shaped structure, the present utility model adopts a test bench 8, which is arranged in the detection straight groove 5 and its upper surface is flush with the upper surface of the base 1; a test positioning part 9, the test positioning part 9 is protruded on the inner and outer sides of the test bench 8, and the test positioning part 9 is matched with the circular groove 6; an arc-shaped protrusion 10, which is protruded on the upper surface of the test bench 8, and its inner side surface is adapted to abut against the outer side surface of the arc-shaped resistance strip;

[0026] When testing the arc-shaped structural resistance strip, the test bench is installed in the detection straight groove. The detection straight grooves on both sides of the detection straight groove match the circular grooves to prevent the test bench from moving in the detection straight groove. The arc-shaped protrusion is arranged on the upper surface of the test bench and can fit the arc-shaped resistance strip, playing a role in positioning the arc-shaped resistance strip. The pressing test part descends, and the pressing end presses on the arc-shaped resistance strip. After the detection is completed, the pressing end ascends, rotates the resistance strip, and detects the next position to realize the resistance detection of the arc-shaped resistance strip.

[0027] As Figure 2 , 4 shown, in order to more accurately test the resistance performance of the arc-shaped resistance strip, the present utility model adopts that an avoidance notch 11 is formed on the arc-shaped protrusion 10; when the pressing end 7 of the pressing test part 3 descends, a part of the pressing end 7 is located at the avoidance notch 11;

[0028] By setting the avoidance notch, after the pressing end descends, the pressing end does not interfere with the arc-shaped protrusion, and the pressing end can completely cover the width of the resistance strip, more accurately testing the resistance performance of the arc-shaped resistance strip.

[0029] Taking the ideal embodiment of the present utility model as the inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model.
