Description

Technical Field

[0001] The invention relates to the technical field of flat copper wire testing, in particular to a flat copper wire tension testing device. Background Art

[0002] Flat copper wire is a copper wire with a flat cross-section and excellent electrical conductivity and mechanical properties. Flat copper wire is usually used to manufacture electronic components such as motors, transformers, relays, etc. It plays an important role in many fields such as electronics and new energy vehicles. In order to reduce the occurrence of flat copper wire being broken during use, there are certain requirements for the tensile strength of flat copper wire. Therefore, in the production process of flat copper wire, in order to ensure the production quality of flat copper wire, tensile testing equipment is usually used to perform tensile tests on flat copper wire.

[0003] When a flat copper wire is subjected to a tensile test by means of a tensile testing device, the two ends of the flat copper wire sample are clamped and fixed by means of the upper and lower clamps of the testing device respectively, and then relevant test parameters are set, a tensile test is performed on the flat copper wire, and measurement and recording are performed by means of a tensile sensor. However, after the flat copper wire is clamped and fixed, the clamping force on the flat copper wire may be too large or too small. An excessive clamping force may cause the flat copper wire to break prematurely during the tensile test, or cause uneven deformation of the flat copper wire during the test, thereby affecting the accuracy and reliability of the test results. An excessively small clamping force may cause the flat copper wire to slip or detach during the test, thereby also affecting the test results.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 11 The present invention provides a technical solution: a flat copper wire tension test device, comprising: a device body 11, a crossbeam 12 is arranged on the device body 11, and a tension sensor 13 is installed on the lower side of the crossbeam 12, The device also includes: a clamping assembly 2, which is arranged on the device body 11 and is used for clamping and fixing the flat copper wire and adjusting the clamping force; The auxiliary component 3 is arranged on one side of the clamping component 2, and is used to assist the clamping component 2 in adjusting the clamping force of the flat copper wire.

[0020] The flat copper wire is subjected to a tension test by means of the tension test device body 11, and the crossbeam 12 is driven up and down by the tension test device body 11 to adjust the height position, so that the clamping assembly 2 can clamp and fix the upper and lower ends of the flat copper wire sample. During the test, the crossbeam 12 is driven up by the tension test device body 11, and the tension sensor 13 is used to detect the tension during the test of the flat copper wire to perform a tension test on the flat copper wire. Furthermore, the clamping force of the flat copper wire can be adjusted according to the width and thickness of the flat copper wire by means of the clamping assembly 2 to prevent the clamping force of the flat copper wire from being too large or too small, which may cause the flat copper wire to be damaged due to excessive clamping force. Premature breakage during the tensile test or uneven deformation of the flat copper wire during the test, and too small clamping force may cause the flat copper wire to slip or detach during the test, thereby affecting the accuracy and reliability of the test results. When clamping the flat copper wire, the clamping component 2 can vertically center the flat copper wire to prevent the flat copper wire from deflecting or twisting after clamping, which affects the uniform force of the flat copper wire in the tensile test and affects the test results. Through the auxiliary component 3, if the flat copper wire slips during the test, the clamping force of the clamping component 2 on the flat copper wire can be further adjusted to improve the accuracy of the test results.

[0021] The clamping assembly 2 includes a lower clamping seat 21 fixedly mounted on the equipment body 11, an upper clamping seat 22 fixedly mounted on the lower side of the tension sensor 13, the upper clamping seat 22 corresponds to the lower clamping seat 21 in upper and lower positions, a cylinder 23 is fixedly arranged on one side of the lower clamping seat 21 and the upper clamping seat 22, the telescopic ends of the two cylinders 23 movably penetrate one side of the lower clamping seat 21 or the upper clamping seat 22, a clamp 24 is fixedly arranged on the telescopic ends of the two cylinders 23, and the air inlet of the cylinder 23 is connected to a compressed air supply device through a pipeline, and the compressed air supply device is used to supply air to the lower clamping seat 21. Compressed gas is introduced into the cylinder 23 to drive the extension and retraction of the telescopic end of the cylinder 23, thereby driving the movement of the clamp 24 to clamp the flat copper wire between the clamp 24 and the lower clamp seat 21 or the upper clamp seat 22; three support members 25 are fixedly arranged at equal intervals on the upper side of the lower clamp seat 21, and a bidirectional screw 26 is rotatably arranged on the support member 25. Moving blocks 29 are threadedly arranged on both sides of the bidirectional screw 26, and a positioning member 210 is fixedly arranged on one side of the two moving blocks 29, and a second detection member 216 is slidably arranged on the upper side of the positioning member 210 on one side.

[0022] A connecting block 211 is symmetrically fixedly arranged on the upper side of the positioning member 210 on one side, and a threaded rod 212 threadedly arranged with the second detection member 216 is rotatably arranged between the two connecting blocks 211. The two ends of the threaded rod 212 respectively penetrate the connecting blocks 211 on both sides and extend to the outside. The threaded rod 212 is located on both sides of the connecting block 211 and is fixedly provided with a ring 213. The ring 213 can limit the rotation of the threaded rod 212. A second knob 214 is fixedly arranged at one end of the threaded rod 212. A limiting block 242 is fixedly arranged on the lower side of the second detection member 216. A sliding groove 241 adapted to the limiting block 242 is opened on the upper side of the positioning member 210 on one side, and the limiting block 242 moves along the sliding groove 24 The sliding arrangement can guide and limit the movement of the second detection member 216. A first detection member 215 is fixedly arranged on the upper side of the positioning member 210 on one side. The threaded rod 212 movably penetrates the first detection member 215. Balls 217 are movably arranged on the sides where the first detection member 215 and the second detection member 216 are close to each other. Limiting grooves matching the ball 217 are arranged on the sides where the first detection member 215 and the second detection member 216 are close to each other. The ball 217 is movably arranged in the limiting groove, and the end surface of the ball 217 on the side of the first detection member 215 close to the second detection member 216 is in the same vertical plane as the inner end surface of the lower clamping seat 21 away from the clamping member 24.

[0023] When in use, the second knob 214 can be rotated to drive the threaded rod 212 to rotate, so that the second detection member 216 can move away from the first detection member 215 along the slide groove 241 through the limit block 242, and the flat copper wire sample to be tested can be placed between the first detection member 215 and the second detection member 216 and located within the clamping range of the clamp 24. The second knob 214 can be rotated in the opposite direction to move the second detection member 216 closer to the first detection member 215, and the flat copper wire can be preliminarily clamped by the second detection member 216 and the first detection member 215. After clamping, the balls 217 on the side where the first detection member 215 and the second detection member 216 are close to each other can respectively contact the two sides of the flat copper wire, and one side of the flat copper wire can contact the inner end face of the lower clamp seat 21 away from the clamp 24.

[0024] The two ends of the bidirectional screw 26 respectively pass through the support members 25 on both sides and extend to the outside. A first knob 28 is fixedly set at one end of the bidirectional screw 26. Limit rings 27 are fixedly set on both sides of the bidirectional screw 26 on the support members 25. The limit rings 27 can limit the rotation of the bidirectional screw 26. A sliding rod 240 is fixedly set between every two support members 25. The moving blocks 29 on both sides are slidably set with the sliding rods 240 on both sides. The sliding rods 240 can guide and limit the movement of the moving blocks 29.

[0025] After the flat copper wire is initially clamped by the second detection member 216 and the first detection member 215, the first knob 28 can be rotated to drive the bidirectional screw 26 to rotate, so that the moving blocks 29 on both sides can be synchronously moved close to each other, and then the positioning members 210 on both sides can be moved close to each other to clamp and resist the other two sides of the flat copper wire, so that the positioning members 210 on both sides can be used to vertically straighten the flat copper wire and make the flat copper wire in a vertically centered state. When the flat copper wire is vertically straightened, the setting of the ball 217 can prevent the flat copper wire from contacting the first detection member 215 or the second detection member 216. Greater wear is generated between them, which affects the tensile test of the flat copper wire, and it is convenient to vertically straighten the flat copper wire to prevent the flat copper wire from being skewed or twisted after being clamped and fixed, which affects the uniform force in the tensile test of the flat copper wire and affects the test result. Subsequently, the cylinder 23 is controlled to work, and compressed gas is introduced into the cylinder 23 through the compressed air supply equipment to drive the telescopic end of the cylinder 23 to extend, so that the clamp 24 moves close to the flat copper wire, so as to clamp and fix the upper and lower ends of the flat copper wire sample through the upper clamp seat 22, the lower clamp seat 21 and the upper and lower clamps 24 respectively.

[0026] A mounting shell 223 is fixedly provided on one side of the lower clamping seat 21, and a first sliding rheostat 224 is fixedly provided in the mounting shell 223. The first sliding rheostat 224 is electrically connected to a compressed air supply device that introduces compressed gas into the cylinder 23, and the coil resistance of the first sliding rheostat 224 close to the side of the lower clamping seat 21 is connected to the circuit. A connecting piece 225 is fixedly provided on the sliding piece of the first sliding rheostat 224. The connecting piece 225 movably penetrates the side end of the mounting shell 223 and slides along the mounting shell 223. A first guide rod 226 that is slidably penetrates the connecting piece 225 is fixedly provided on the inner side of the mounting shell 223. The first guide rod 226 can guide the movement of the connecting piece 225, and a first spring 227 that is fixedly provided on one side of the connecting piece 225 and is fixedly provided with the lower clamping seat 21.

[0027] A first bevel gear 218 is fixedly provided at one end of the threaded rod 212 away from the second knob 214, and the first bevel gear 218 is meshedly connected with the second bevel gear 219. A first gear 220 is fixedly provided on one side of the second bevel gear 219. A support rod 228 fixedly provided with a side moving block 29 is rotatably provided in the middle of the second bevel gear 219 and the first gear 220. A first toothed condition 221 slidably provided with a side positioning member 210 is meshedly connected at the lower side of the first gear 220. A first guide groove 222 is provided on a side of the side positioning member 210 close to the first toothed condition 221. The first toothed condition 221 is slidably provided along the first guide groove 222. The first guide groove 222 is adapted to the first toothed condition 221. The first guide groove 222 can support and guide the first toothed condition 221. A push rod 229 is fixedly provided at one end of the first toothed condition 221, and the push rod 229 is located on one side of the connecting member 225.

[0028] When the second knob 214 is rotated to drive the threaded rod 212 to rotate and the second detection member 216 moves away from the first detection member 215, the first bevel gear 218 can be driven to rotate, so that the second bevel gear 219 can be rotated, and then the first gear 220 can be rotated, so that the first gear 221 moves along the first guide groove 222 close to the second knob 214, so that the push rod 229 pushes the connecting member 225 to move close to the lower clamping seat 21, and the first spring 227 is compressed, so that the connecting member 225 can drive the sliding piece of the first sliding rheostat 224 to move close to the lower clamping seat 21, so that the resistance value of the first sliding rheostat 224 connected to the circuit is reduced. For a thicker flat copper wire, the second detection member 216 moves a longer distance away from the first detection member 215, and the second knob 229 is rotated to rotate the first bevel gear 218, so that the second gear 220 can rotate, so that the first gear 221 moves along the first guide groove 222 close to the second knob 214, and the push rod 229 pushes the connecting member 225 to move close to the lower clamping seat 21, and the first spring 227 is compressed, so that the connecting member 225 can drive the sliding piece of the first sliding rheostat 224 to move close to the lower clamping seat 21, so that the resistance value of the first sliding rheostat 224 connected to the circuit is reduced. For a thicker flat copper wire, the second detection member 216 moves a longer distance away from the first detection member 215, and the second knob 229 is rotated to rotate the first bevel gear 218, so that the second gear 220 can rotate, so that the first gear 221 moves closer to the second knob 229, and the first 214 drives the threaded rod 212 to rotate with a relatively large amplitude or number of circles, so that the first tooth condition 221 can drive the push rod 229 to push the connecting piece 225 to move a larger distance, so that the resistance value of the first sliding rheostat 224 connected to the circuit is reduced more, so that the power of the compressed air supply device that passes compressed gas into the cylinder 23 is increased more, so that for thicker flat copper wires, the compressed air supply device passes more compressed gas into the cylinder 23, so that the air pressure in the cylinder 23 is larger, and the clamping force of the clamp 24 on the flat copper wire is larger, so as to ensure the clamping effect on the thicker flat copper wire; on the contrary, for thinner flat copper wires, the clamping force on the flat copper wire can be increased relatively less to prevent excessive clamping effect on the thinner flat copper wires.

[0029] A second gear 230 is fixedly arranged at one end of the bidirectional screw 26 away from the first knob 28, and a second gear condition 231 slidably arranged with a side support member 25 is meshedly connected at the lower side of the second gear 230, and a second guide groove 232 is provided on a side of the side support member 25 close to the second gear condition 231, and the second gear condition 231 is slidably arranged along the second guide groove 232, and the second guide groove 232 is adapted to the second gear condition 231, and the second guide groove 232 can support and guide the second gear condition 231; A sleeve rod 233 is fixedly provided on one side of the second gear condition 231, and a connecting rod 234 fixedly provided with the connecting member 225 is slidably provided inside the sleeve rod 233, and a beveled tooth block 235 is slidably provided inside the connecting rod 234 near the sleeve rod 233. A beveled tooth groove matching the beveled tooth block 235 is provided on the inner side of the sleeve rod 233, and a fixing rod 236 that movably passes through the connecting rod 234 is fixedly provided on the upper side of the beveled tooth block 235. A through groove 239 matching the fixing rod 236 is provided on the upper side of the sleeve rod 233, and the fixing rod 236 is slidably provided along the through groove 239, and the through groove 239 can also limit the movement of the connecting rod 234. A pulling block 238 is fixedly provided on the upper end of the fixing rod 236, and a second spring 237 fixedly provided with the connecting rod 234 is fixedly provided on the upper side of the beveled tooth block 235; When the push rod 229 pushes the connecting member 225 to move close to the lower clamping seat 21, the connecting member 225 will drive the connecting rod 234 to move synchronously, and the fixing rod 236 will move along the through groove 239. The setting of the bevel gear block 235 does not hinder the movement of the connecting rod 234 close to the lower clamping seat 21, that is, it does not hinder the movement of the connecting rod 234 to the inner side of the sleeve rod 233. The bevel gear block 235 is moved up and down reciprocatingly through the bevel gear groove on the inner side of the sleeve rod 233 that matches the bevel gear block 235. The second spring 237 repeatedly expands and contracts. When the first knob 28 is rotated to drive the bidirectional screw 26 to rotate, the positioning members 234 on both sides are moved. When the two sides of the flat copper wire are clamped and contacted, the rotation of the bidirectional screw 26 can drive the second gear 230 to rotate, so that the second gear condition 231 moves along the second guide groove 232 close to the second knob 214, thereby driving the sleeve rod 233 to move synchronously with the second gear condition 231, and through the beveled tooth block 235 and the beveled tooth groove inside the sleeve rod 233, the beveled tooth block 235 can be driven to move with the sleeve rod 233, and then the connecting rod 234 can be driven to move, so that the connecting member 225 drives the sliding piece of the first sliding rheostat 224 to move close to the lower clamping seat 21, so as to adjust the flat copper wire according to the position of the flat copper wire. The width is adjusted by adjusting the resistance value of the first sliding rheostat 224 connected to the circuit, thereby adjusting the clamping force on the flat copper wire. For a flat copper wire with a smaller width, the positioning member 210 moves a larger distance when clamping and resisting the other two sides of the flat copper wire. The first knob 28 drives the bidirectional screw 26 to rotate by a relatively large amplitude or number of turns, so that the second gear condition 231 moves a larger distance close to the second knob 214, so that the sleeve rod 233 drives the connecting rod 234 to move a larger distance, and then the connecting member 225 drives the sliding piece of the first sliding rheostat 224 to move close to the lower clamping seat 21. The first sliding rheostat 224 is connected to the cylinder 23, and the resistance value of the first sliding rheostat 224 in the circuit is reduced more, so that the power of the compressed air supply device that passes the compressed gas into the cylinder 23 is increased more. For the flat copper wire with a smaller width, the compressed air supply device passes a larger amount of compressed gas into the cylinder 23, so that the air pressure in the cylinder 23 is larger, and the clamping force of the clamp 24 on the flat copper wire is larger, so as to ensure the clamping effect on the flat copper wire with a smaller width, so that the clamping force on the flat copper wire can be adjusted according to the width and thickness of the flat copper wire through the clamping component 2 to prevent the clamping force on the flat copper wire from being too large or too small; After the tension test of the flat copper wire is completed, the first knob 28 can be rotated in the opposite direction to move the two positioning members 210 away from each other, and the telescopic end of the cylinder 23 can be controlled to drive the clamp 24 to move in the opposite direction and reset, so as to take out the flat copper wire, and by pulling the pull block 238 upward, the bevel tooth block 235 can be moved upward to disengage from the bevel tooth groove on the inner side of the sleeve rod 233, and under the elastic force of the first spring 227, the connecting member 225 drives the sliding piece of the first sliding rheostat 224 to move in the opposite direction and reset, and the connecting member 225 can drive the connecting rod 234 to move in the opposite direction and reset.

[0030] In the second embodiment, the auxiliary component 3 includes a pressing block 31 slidably arranged with the upper clamping seat 22, a connecting shell 32 is fixedly arranged on one side of the upper clamping seat 22, a second sliding rheostat 33 is fixedly arranged in the connecting shell 32, the second sliding rheostat 33 and the control switch 310 are electrically connected to the compressed air supply device that introduces compressed gas into the cylinder 23, and the coil resistance on the lower side of the second sliding rheostat 33 is connected to the circuit, the sliding piece of the second sliding rheostat 33 is fixedly arranged with a transmission member 34 fixedly arranged with the pressing block 31, the transmission member 34 movably penetrates the side end of the connecting shell 32 and slides along the connecting shell 32, a mounting block 39 is fixedly arranged on the side of the upper clamping seat 22 close to the connecting shell 32, and a control switch 310 is installed on the lower side of the mounting block 39, and initially, the control switch 310 is in a state of being pressed by the transmission member 34; The upper clamping seat 22 is located on one side of the pressure block 31 and is provided with a through groove 38 adapted to the transmission member 34. The transmission member 34 is slidably arranged along the through groove 38. A second guide rod 35 is fixedly arranged on the inner side of the connecting shell 32 and is slidably arranged through the transmission member 34. The second guide rod 35 can guide the movement of the transmission member 34. A third spring 37 is fixedly arranged on the upper side of the transmission member 34. A fixing block 36 fixedly arranged on the upper side of the third spring 37 and fixedly arranged on the upper side of the upper clamping seat 22.

[0031] When the upper end of the flat copper wire is clamped and fixed by the upper clamp 24 and the upper clamp seat 22, the flat copper wire can be clamped on the outside of the pressure block 31. If the flat copper wire slips during the test, the upper end of the flat copper wire will move downward relative to the upper clamp seat 22. Through the compression between the flat copper wire and the pressure block 31, the pressure block 31 can move downward relative to the upper clamp seat 22, so that the transmission member 34 drives the slider of the second sliding rheostat 33 to move downward, so that the resistance value of the second sliding rheostat 33 connected to the circuit is reduced, so that the power of the compressed air supply device that introduces compressed gas into the cylinder 23 is increased, and the downward movement of the transmission member 34 relative to the upper clamp seat 22 can make the transmission member 34 no longer press the control switch 310, so as to control the compressed air supply device and the cylinder 23 to work for a certain time. During this time, compressed air is introduced into the cylinder 23 through the compressed air supply equipment, so that the upper clamping seat 22, the lower clamping seat 21 and the upper and lower clamps 24 respectively increase the clamping force on the upper and lower ends of the flat copper wire to prevent the flat copper wire from further slipping; and when the flat copper wire slips a relatively large distance, the pressure block 31 will move down a relatively large distance, and then the sliding piece of the second sliding rheostat 33 will move down a relatively large distance, so that the power of the compressed air supply equipment is increased more, so that within the set working time, the compressed air supply equipment introduces a large amount of compressed gas into the cylinder 23, so that the clamping force of the clamp 24 on the flat copper wire is increased more, so as to effectively prevent the flat copper wire from slipping, and prevent the clamping force on the flat copper wire from being too large or too small after adjustment.
