[0002] During the production and processing of copper rods, their straightness needs to be tested to ensure that the copper rods produced and processed meet the standards.

[0003] At present, most of the practices adopt manual measurement, such as a copper rod straightness detection device with Chinese patent publication number CN212300229U, which includes a base fixing plate, a bottom detection strip is fixedly installed on the upper surface of the base fixing plate, a movable groove is provided on the inner side of the bottom detection strip, a copper rod fixing block is arranged on the upper surface of the bottom detection strip, a copper rod clamp is fixedly installed on the upper surface of the copper rod fixing block, a movable screw is threadedly installed on the inner side of the copper rod clamp, a copper rod top block is fixedly installed on one end of the movable screw, and a rotating handle is fixedly installed on the other end of the movable screw.

[0004] During the measurement, the copper rod is fixed on the fixture, and then the verticality of the copper rod is measured by tools such as micrometers.

[0027] The embodiment of the present invention provides a copper rod multi-angle axial linear detection device, such as Figure 1-5 As shown, it includes a base 1, a clamping mechanism 2, and a detection mechanism 3.

[0028] like Figure 1 As shown, the clamping mechanism 2 is arranged on the base 1 and is used to clamp the copper rod 14. The clamping mechanism 2 includes a slide rail 21, a bottom clamp seat 22, a top plate 25, and a top clamp seat 27. The slide rail 21 is vertically arranged on the base 1, and the bottom clamp seat 22 is rotatably arranged on the base 1. A slide groove is vertically provided on the slide rail 21. The top plate 25 is vertically slidably adapted in the slide groove of the slide rail 21 through a slider. A spring 26 is arranged between the top of the top plate 25 and the top of the slide rail 21. The spring 26 provides tension for the top plate 25 so that the top plate 25 can squeeze the copper rod 14 between the top clamp seat 27 and the bottom clamp seat 22. The top clamp seat 27 is rotatably arranged at the bottom of the top plate 25 and corresponds to the bottom clamp seat 22. A turntable 28 coaxially connected to the top clamp seat 27 is arranged on the top of the top plate 25. When the copper rod 14 is clamped between the top clamping seat 27 and the bottom clamping seat 22 , the copper rod 14 is controlled to rotate by the turntable 28 to achieve measurement on multiple circumferential axes.

[0029] The bottom clamp seat 22 is longitudinally slidably adapted to have two clamping plates 23 for clamping the copper rod 14. A handle 24 for connecting the clamping plates 23 is provided on the outside of the bottom clamp seat 22. A linkage mechanism 5 for linking the two clamping plates 23 is also provided inside the bottom clamp seat 22. The clamping plates 23 are arc-shaped, and their arc shape matches the appearance of the copper rod 14. A spring is provided between the back of the clamping plates 23 and the bottom clamp seat 22, and the clamping plates 23 clamp the copper rod 14 by using the tension of the spring.

[0030] like Figure 5As shown, in order to clamp the copper rod 14 at the center of the bottom clamp seat 22, a linkage mechanism 5 is provided to make the two clamping plates 23 move toward or away from each other in a linkage manner, so that the copper rod 14 can be clamped at the center of the bottom clamp seat 22. The specific linkage mechanism 5 includes a driving gear 51 and a linkage rack 1 52 and a linkage rack 2 53 meshed on both sides of the driving gear 51, and the linkage rack 1 52 and the linkage rack 2 53 are respectively connected to the two clamping plates 23. By providing the driving gear 51 to cooperate with the linkage rack 1 52 and the linkage rack 2 53 on both sides, the two clamping plates 23 can be synchronously moved toward or away from each other.

[0031] like Figure 2 and Figure 4 As shown, the detection mechanism 3 includes a polygonal measuring cylinder 31 and several groups of detection components. In this embodiment, the measuring cylinder 31 is at least a decagon, and ten groups of corresponding detection components are also provided. The ten groups of detection components are arranged circumferentially and equidistantly along the measuring cylinder 31. Each group of detection components includes at least ten groups of measuring rods 32, sliding cavities 34, and springs 35. The sliding cavities 34 are transversely opened on the measuring cylinder 31. The ten groups of sliding cavities 34 are arranged equidistantly along the axial direction of the measuring cylinder 31. The ten measuring rods 32 are slidably adapted in the sliding cavities 34 one by one. The outer ends of the measuring rods 32 extend outside the measuring cylinder 31 and correspond to the copper rod 14. The inner ends are connected to the inner ends of the sliding cavities 34 through springs 35. The measuring rods 32 are provided with measuring scales 36 along their length direction. The length of the extended measuring rods 32 is determined by measuring the scales 36, thereby determining the verticality of the copper rod 14.

[0032] The base 1 is provided with calibration scales 8 along its transverse direction, a slideway 7 is provided transversely on the base 1, a sliding seat 6 is slidably adapted on the slideway 7, a measuring tube 31 is pivotally connected to the sliding seat 6, a pointer 9 corresponding to the calibration scale 8 is provided on the sliding seat 6, a fixing plate extending and bending toward the edge of the base 1 is provided on one side of the sliding seat 6, and a locking bolt 10 corresponding to the base 1 is threadedly connected to the fixing plate of the sliding seat 6. When the sliding seat 6 is adjusted to the corresponding position, the locking bolt 10 is pressed against the base 1 to achieve the locking of the sliding seat 6.

[0033] The measuring cylinder 31 is provided with a locking mechanism 4 which can lock or unlock the lateral displacement of the measuring rod 32 with one click.

[0034] like Figure 4 and Figure 5As shown, there are several locking mechanisms 4, and the number of locking mechanisms 4 is consistent with the number of detection components. Each locking mechanism 4 corresponds to a group of detection components, and the locking mechanism 4 includes a toggle rack 45 and several groups of magnetic blocks 1 41, rotating blocks 43, magnetic blocks 2 44, and rotating gears 46, which are the same as the number of measuring rods 32. A vertical groove 47 for vertical sliding of the toggle rack 45 is vertically arranged on the measuring cylinder 31, and the bottom of the toggle rack 45 is connected to the bottom of the vertical groove 47 through a spring. A gear cavity 42 is arranged above each measuring rod 32 in the measuring cylinder 31, and the gear cavity 42 is connected to the vertical groove 47. The rotating gear 46 is pivoted in the gear cavity 42 and meshed with the toggle rack 45. When the toggle rack 45 is vertically displaced, it can drive the rotating gear 46 meshed with it to rotate. The magnetic block 1 41 is arranged on the top of the measuring rod 32, the rotating block 43 is coaxially connected to the rotating gear 46, and the magnetic block 2 44 is arranged at the bottom of the rotating block 43 and corresponds to the magnetic block 1 41. When the second magnetic block 44 corresponds to the first magnetic block 41 , the magnetic poles of the corresponding surfaces of the two are opposite.

[0035] Under normal conditions, the toggle rack 45 is in a relaxed state under the action of the spring, in which the second magnetic block 44 at the bottom of the rotating block 43 corresponds exactly to the first magnetic block 41, and the second magnetic block 44 adsorbs the first magnetic block 41 to lock the shape of the measuring rod 32. When the toggle rack 45 is displaced downward to the limit distance by an external force, the rotating gear 46 rotates at an angle of at least 90°, so that the bottom surface of the second magnetic block 44 is separated from the first magnetic block 41, and the two lose their adsorption force, and the measuring rod 32 can move freely in the horizontal direction.

[0036] A positioning convex head 29 is provided on the top of the top plate 25, and a plurality of grooves for the positioning convex head 29 to be inserted into are provided in a circumferential direction at the bottom of the turntable 28. There are ten grooves, which are distributed at equal angles around the center of the turntable 28. The top height of the positioning convex head 29 is slightly higher than the bottom height of the turntable 28. The positioning convex head 29 is made of rubber or PVC. When the turntable 28 rotates 36 degrees, the positioning convex head 29 can be inserted into the corresponding groove to achieve positioning every 36 degrees.

[0037] The end of the detection rod 32 corresponding to the copper rod 14 is provided with a hemispherical detection head 33. The hemispherical detection head 33 can reduce the friction between the detection rod 32 and the copper rod 14.

[0038] like Figure 1 As shown, a T-shaped connecting rod 12 is vertically slidably connected to the top plate 25, a pressing block 11 is arranged at the bottom end of the connecting rod 12, a spring 13 is sleeved between the top end of the connecting rod 12 and the top plate 25, and the height of the pressing block 11 is slightly higher than the top surface height of the measuring cylinder 31 under normal conditions, and the pressing block 11 is used to guide the pressing of the toggle rack 45. When the toggle rack 45 is located below the pressing block 11, the length of the pressed toggle rack 45 can drive the rotating gear 46 to rotate at least 90°.

[0039] A multi-angle axial linear detection method for copper rods:

[0040] Step 1: First, clamp the model rod of standard size between the bottom clamp seat 22 and the top clamp seat 27.

[0041] Step 2: Move the measuring cylinder 31 toward the model rod until the end of the measuring rod 32 contacts the model rod, and record the measurement scale at this time as A. Then continue to move 5mm toward the model rod, record the measurement at this time as A-5mm, and record the calibration scale on the measuring cylinder 31 as a.

[0042] Step 3: the measuring tube 31 is moved outwards, and then the model rod is removed.

[0043] Step 4: clamp the copper rod 14 to be tested between the bottom clamping seat 22 and the top clamping seat 27 .

[0044] Step five: move the measuring cylinder 31 horizontally to the position where the calibration scale is a, and lock the sliding seat 6 on the base 1.

[0045] Step six, rotate the measuring tube 31 to make the first group of measuring rods 32 contact the copper rod 14. At this time, the pressing block 11 presses the sliding rack 45 corresponding to the first group of measuring rods 32, so that the contact surface of the magnetic block 1 41 and the magnetic block 2 42 are separated, so that the first group of measuring rods 32 can slide freely horizontally.

[0046] Step seven, lift the pressing block 11 upwards to reset the toggle rack 45 upwards, so that the contact surfaces of the first magnetic block 41 and the second magnetic block 42 correspond to each other, and the shape of the first group of measuring rods 32 is locked.

[0047] Step eight, firstly rotate the measuring tube 31 and the copper rod 14 synchronously by 36 degrees, and then release the pressing block 11 to move the rack 45 downward, so that the second set of measuring rods 32 can slide freely horizontally.

[0048] Step nine, repeating steps seven to eight until the ten groups of measuring rods 32 of the measuring tube 31 have measured ten groups of axes around the copper rod 14.

[0049] Step ten, move the measuring tube 31 horizontally out of the range of the pressing block 11, and then observe the values ​​on each group of measuring rods 32, with the value A-5 as the 0 reference. If the value is A-4, the size of the copper rod 14 at this point is smaller than the standard by 1mm, and if the value is A-6, the size of the copper rod 14 at this point is larger than the standard by 1mm.
