Description

Technical Field

[0001] The utility model belongs to the technical field of copper busbar inspection, and particularly relates to a clamping tool for copper busbar inspection. Background Art

[0002] Copper busbar, also known as copper busbar or copper busbar, is a long conductor made of copper. Its cross-section is usually rectangular or chamfered (rounded) rectangular. It is widely used in electrical equipment due to its excellent conductivity. During the processing of copper busbar, it usually needs to be bent several times to facilitate the transmission of current and the connection of electrical equipment. The processed copper busbar also needs to be inspected. During the inspection, the copper busbar is fixed on the clamping tool, and the user uses a measuring tool to measure the size and position of the copper busbar to check whether the size and position of the copper busbar after bending meet the expected requirements.

[0003] During use, the existing clamping tool for copper busbar inspection usually clamps and fixes the copper busbar before measuring the size and position of the copper busbar with tools such as vernier calipers. If the copper busbar is bent many times, more size positions need to be measured, resulting in the user needing to frequently use tools such as vernier calipers on multiple locations on the copper busbar, which is not convenient enough and the inspection efficiency is insufficient.

[0050] like Figure 1 and Figure 2 As shown, the copper busbar 20 includes a plate body 21 placed above the base plate 10, a first end portion 22 integrated with one end of the plate body 21, a bent portion 23 integrated with the other end of the plate body 21, a second end portion 24 integrated with the bent portion 23 and away from one end of the plate body 21, and a raised portion 25 integrated with the lower end of the plate body 21.

[0054] In this embodiment, when it is necessary to check the size and position of the first through hole 221, after the copper busbar 20 is positioned and clamped, the first detection pin 32 is inserted into the first through hole 221 and the first support block 31. If the first detection pin 32 is inserted, it indicates that the size and position of the first through hole 221 are as expected, thereby facilitating the inspection of the size and position of the first through hole 221.

[0055] like Figure 1 and Figure 4 As shown, the second support mechanism 50 includes a second support block 51 fixedly connected to the top of the base plate 10, the second support block 51 is fitted with the bottom of the second end portion 24, the second support block 51 is fitted with the side of the second end portion 24, and a second detection pin 52 is slidably penetrated through the top of the second support block 51, and the second detection pin 52 is slidably fitted with the second through hole 241.

If the second detection pin 52 is inserted, it indicates that the size and position of the second through hole 241 are as expected, thereby facilitating the inspection of the size and position of the second through hole 241.

[0059] It should be noted that the first spring 73 is located above the rotation center of the first pressing block 72 .

[0060] In this embodiment, after the copper busbar 20 is positioned, the first spring 73 pushes the first pressure block 72 to rotate toward the side close to the second supporting mechanism 50 under the action of elasticity, so that the distance between the first pressure block 72 and the second supporting mechanism 50 is reduced, so that the first pressure block 72 and the second supporting mechanism 50 limit the copper busbar 20 along the horizontal plane, thereby avoiding the situation where the copper busbar 20 is offset along the horizontal plane when detecting the copper busbar 20 and affecting the inspection result, thereby facilitating the inspection of the size position of the copper busbar 20.

[0061] like Figure 1 and Figure 6As shown, the limiting mechanism 80 includes a limiting block 81 fixedly connected to the top of the base plate 10, the limiting block 81 is in contact with the outer side of the plate body 21, a third detection pin 82 is slidably penetrated inside the limiting block 81, and the third detection pin 82 is slidably matched with the protrusion 25.

[0062] It should be noted that a detection groove is formed at one end of the third detection pin 82 close to the protrusion 25 , and the size of the detection groove matches the size of the protrusion 25 .

[0063] In this embodiment, when it is necessary to check the size and position of the protrusion 25, after the copper busbar 20 is positioned and clamped, the third detection pin 82 is inserted into the interior of the limit block 81 and moved toward the side close to the protrusion 25. If the protrusion 25 is inserted into the detection groove of the third detection pin 82, it indicates that the size and position of the protrusion 25 are as expected, thereby facilitating the inspection of the size and position of the protrusion 25.

[0065] It should be noted that the second spring 93 is located on the upper side of the rotation center of the second pressing block 92 .

[0066] In this embodiment, after the copper busbar 20 is positioned, the second spring 93 pushes the second pressure block 92 to rotate toward the side close to the limiting mechanism 80 under the action of elasticity, so that the distance between the second pressure block 92 and the limiting mechanism 80 is reduced, so that the second pressure block 92 and the limiting mechanism 80 limit the copper busbar 20 along the horizontal plane, avoiding the situation where the copper busbar 20 is offset along the horizontal plane when detecting the copper busbar 20 and affecting the inspection result, thereby facilitating the inspection of the size position of the copper busbar 20.

[0069] In this embodiment, when it is necessary to inspect the size and position of the bending portion 23, after the copper busbar 20 is positioned and clamped, the fourth detection pin 102 is inserted into the protrusion 101 from the inner side of the bending portion 23, and the fourth detection pin 102 drives the first movable detection block 1021 to move downward, and the fifth detection pin 103 is inserted into the protrusion 101 from the outer side of the bending portion 23, and the fifth detection pin 103 drives the second movable detection block 1031 to move downward.

After the action, the plate body 21 is limited by the limiting mechanism 80, the first supporting mechanism 30 detects the size position of the first through hole 221 after the action, the second supporting mechanism 50 detects the size position of the second through hole 241 after the action, the movable detecting mechanism 100 detects the size position of the bending portion 23 after the action, and the limiting mechanism 80 detects the size position of the protruding portion 25 after the action, thereby facilitating the inspection of the size position of the copper busbar 20, avoiding the situation in which the traditional inspection method requires tools such as vernier calipers to frequently measure on the copper busbar 20, thereby improving convenience and inspection efficiency.
