Description

Technical Field

[0001] The invention belongs to the technical field of cable production detection, and in particular relates to a cable production detection device and a detection method. Background Art

[0002] Cables are wire products used to transmit electrical energy, signals and realize electromagnetic energy conversion.

[0003] During the production of cables, they need to be subjected to various tests, one of which is the bending fatigue test of the cable. Specifically, the cable is clamped by the turntable on the bending fatigue testing machine in conjunction with the clamping assembly, and then weights are tied under the cable. The cable is passed through two limit columns and then the turntable is swung back and forth to make the cable swing. When the cable bends, the fatigue of the cable is then determined based on the data displayed on the testing machine.

[0004] However, during the test, when the cable swings, the tension it is subjected to comes not only from the gravity of the weight, but also from the friction between the cable and the limit column. The tension parameter of the cable during the test refers to the gravity of the weight, and this part of the friction is not taken into account. However, the friction between the cable surface and the limit column is actually large. Excessive friction will seriously affect the accuracy of the test results. Summary of the invention

[0008] Furthermore, the extrusion assembly includes: a gap ring, a pressure block, a pair of third springs, inclined surfaces arranged at both ends of the gap ring, and a stopper; An annular groove is provided on the inner side of the notch ring, and the notch ring is sleeved on the outside of the turntable. The pressure block is fixedly connected to the middle part of the top end of the turntable, and the pressure block is slidably arranged in the annular groove. A pair of the third springs are respectively located on both sides of the pressure block and fixedly connect the pressure block to the inner wall of the annular groove. The stopper is fixedly connected to the front side of the machine body and the position of the stopper corresponds to the middle position of the bottom end of the turntable.

[0010] Further, the pulling assembly includes: an iron rod, an electromagnet; The iron rod is fixedly connected to the bottom of the horizontal plate, and the electromagnet is fixedly installed on the bottom wall of the groove.

[0011] Furthermore, the top curvature of the transverse plate is consistent with the curvature of the limiting column, and the side of the transverse plate where the spray hole is opened is located in the middle of the top end of the limiting column.

[0012] Furthermore, the conduit is specifically configured as a hose.

[0013] The present invention also provides a method for testing using the above-mentioned cable production testing device, comprising the following steps: S1. When in use, the turntable swings with the clamping assembly and the cable. When the turntable and the cable swing to the right, the oil injection assembly is used to inject lubricating oil into the cavity in the horizontal plate on the left limit column. The lubricating oil is sprayed onto the surface of the limit column through the spray hole. The lubricating oil slides along the side of the limit column close to the cable, so that the side of the limit column close to the cable, i.e. the inner side, is lubricated; S2.

When the turntable and the cable swing to the left, when the turntable moves to reset, the pulling assembly on the right cancels the pulling on the horizontal plate, and the first spring releases the force to lift and reset the horizontal plate. Then the turntable continues to swing to the left, so that the oil injection assembly injects lubricating oil into the cavity in the horizontal plate on the right limit column. The lubricating oil is sprayed onto the surface of the limit column through the spray hole, so that the limit column on the right is lubricated. At the same time, the pulling assembly drives the left horizontal plate to be retracted into the groove, so as to avoid friction between the left horizontal plate and the subsequent moving cable. Due to the lubrication of the left limit column, when the turntable swings to the left with the cable, the friction between the cable and the left limit column is low; S4. Subsequently, when the turntable and the cable swing to the right, the limit column on the left can continue to be lubricated as above. Similarly, because the limit column on the right is lubricated, the friction between the cable and the limit column on the right is low. Finally, continuous lubrication of the limit columns on both sides is achieved during the swinging of the cable, so that the friction between the cable and the limit columns on both sides is low, thereby avoiding excessive friction affecting the accuracy of the detection results. Through continuous lubrication of the limit columns, the lubricating oil on the surface of the limit columns can be maintained when used under high air flow rates, thereby avoiding the situation where the lubricating oil on the surface of the limit columns is dried up by air, thereby ensuring the lubrication effect.

The present invention realizes continuous lubrication of the limit posts on both sides during the swinging process of the cable, so that the friction between the cable and the limit posts on both sides is low, thereby avoiding excessive friction affecting the accuracy of the detection result.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a cable production detection device, such as Figures 1 to 8 As shown, it includes a body 1, a turntable 2 is provided on the front side of the body 1, a clamping assembly is provided on the front side of the turntable 2, the body 1 is a bending fatigue testing machine, the turntable 2 is a turntable on the bending fatigue testing machine for driving the cable to swing, the clamping assembly is a clamping assembly on the bending fatigue testing machine for fixing the cable, the cable is clamped on the clamping assembly, a weight 4 is provided on the bottom of the cable, and a limiting column 3 is symmetrically provided on the front side of the body 1, and a lubricating assembly for continuously lubricating the limiting column 3 is provided on the outside; The lubrication assembly includes: a transverse plate 5, a first spring 6, a cavity disposed on the transverse plate 5 and a plurality of spray holes 7 connected to the cavity, a pulling assembly for driving the transverse plate 5 to descend, and an oil injection assembly for injecting lubricating oil into the cavity; A groove is formed at the top of the limiting column 3, and a transverse plate 5 is arranged in the groove. The transverse plate 5 is fixedly connected to the bottom wall of the groove through a first spring 6, and the oil injection assembly is communicated with the cavity.

[0018] When in use, the turntable 2 swings with the clamping assembly and the cable. When the turntable 2 and the cable swing to the right, the oil injection assembly is used to inject lubricating oil into the cavity in the horizontal plate 5 on the left limit column 3. The lubricating oil is sprayed onto the surface of the limit column 3 through the spray hole 7. The lubricating oil slides along the side of the limit column 3 close to the cable, so that the side of the limit column 3 close to the cable, i.e. the inner side, is lubricated. At this time, the horizontal plate 5 on the right limit column 3 is pulled by the pulling assembly so that it is retracted into the groove, and at the same time the first spring 6 is compressed to deform it to generate a force. At this time, the right The top of the horizontal plate 5 and the surface of the limiting column 3 form a complete cylindrical surface. By retracting the right horizontal plate 5, when the cable surface swings to the top position of the right limiting column 3, it will not contact the horizontal plate 5, so that the cable will not be affected by the friction force caused by the contact between the horizontal plate 5 and the cable, thereby avoiding this part of the friction force affecting the accuracy of the detection result. When the turntable 2 and the cable swing to the left, when the turntable 2 moves to reset, the pulling component on the right cancels the pulling of the horizontal plate 5, and the first spring 6 releases the force to bring the horizontal plate 5 up and reset, and then the turntable 2 continues to move to the left The swing makes the oil injection assembly inject lubricating oil into the cavity in the transverse plate 5 on the right limiting column 3, and the lubricating oil is sprayed onto the surface of the limiting column 3 through the spray hole 7, so that the limiting column 3 on the right is lubricated. At the same time, the pulling assembly drives the transverse plate 5 on the left to be retracted into the groove, so as to avoid friction between the transverse plate 5 on the left and the subsequent moving cable. Due to the lubrication of the limiting column 3 on the left, when the turntable 2 swings to the left with the cable, the friction between the cable and the limiting column 3 on the left is low. Later, when the turntable 2 and the cable swing to the right, the limiting column 3 on the left can be lubricated in the same way as above. Continue lubrication. At the same time, because the limit column 3 on the right side is lubricated, the friction between the cable and the limit column 3 on the right side is low. Finally, the limit columns 3 on both sides are continuously lubricated during the swinging of the cable, so that the friction between the cable and the limit columns 3 on both sides is low, thereby avoiding excessive friction affecting the accuracy of the detection result. By continuously lubricating the limit column 3, the lubricating oil on the surface of the limit column 3 can be maintained when used under high air flow rate, so as to avoid the situation where the lubricating oil on the surface of the limit column 3 is dried by air, thereby ensuring the lubrication effect.

[0019] like Figures 2 to 3 As shown, the oil injection assembly includes: a cylinder 8, a conduit 9 connecting the cylinder 8 with the cavity, a collecting assembly arranged below the cylinder 8, a suction pipe 10 connecting the cylinder 8 with the collecting assembly, a one-way valve 11 arranged in the spray hole 7 and the suction pipe 10, a piston 12, a push rod 13, a pressure plate 14, a second spring 15, a cross bar 16, an extrusion assembly for extruding the cross bar 16, a filling and collecting assembly, and the lubricating oil in the cylinder 8; The cylinder body 8 is fixed to the outside of the machine body 1 through a connecting rod, the piston 12 is arranged inside the cylinder body 8, the push rod 13 is fixed to the top of the piston 12, the pressure plate 14 is fixedly sleeved on the outside of the push rod 13, the second spring 15 is sleeved outside the push rod 13 and is located between the pressure plate 14 and the cylinder body 8, and the cross bar 16 is fixedly connected to the top of the push rod 13.

[0020] The extrusion assembly squeezes the cross bar 16, causing the push rod 13, the pressure plate 14, and the piston 12 to descend. The pressure plate 14 compresses the second spring 15 to deform it and generate a force. As the piston 12 descends, the lubricating oil in the cylinder 8 is squeezed outward. At this time, the one-way valve 11 in the suction tube 10 is closed, and the lubricating oil enters the cavity through the conduit 9, and then pushes the one-way valve 11 to be ejected through the spray hole 7. The extrusion assembly cancels the squeezing of the cross bar 16. At this time, the compressed second spring 15 releases the force to cause the pressure plate 14, the push rod 13, and the piston 12 to rise, so that the lubricating oil is drawn into the cylinder 8. At this time, the one-way valve 11 in the suction tube 10 is opened, and the one-way valve 11 in the spray hole 7 is closed. At this time, the lubricating oil in the collection assembly is drawn into the cylinder 8 through the suction tube 10 for replenishment.

[0021] like Figures 5 and 6 As shown, the extrusion assembly includes: a notch ring 17, a pressure block 18, a pair of third springs 19, inclined surfaces 20 arranged at both ends of the notch ring 17, and a stopper 21; An annular groove is provided on the inner side of the notch ring 17, and the notch ring 17 is sleeved on the outside of the turntable 2. The pressure block 18 is fixedly connected to the middle of the top end of the turntable 2, and the pressure block 18 is slidably set in the annular groove. A pair of third springs 19 are respectively located on both sides of the pressure block 18 and fix the pressure block 18 to the inner wall of the annular groove. The stopper 21 is fixedly connected to the front side of the body 1 and the position of the stopper 21 corresponds to the middle position of the bottom end of the turntable 2. The elastic coefficient of the third spring 19 is greater than the elastic coefficient of the second spring 15.

[0022] When the turntable 2 swings to the right, the pressure block 18 moves with it, and the pressure block 18 cooperates with the third spring 19 to move with the notched ring 17, and the notched ring 17 cooperates with the inclined surface 20 to squeeze the left cross bar 16 to make it drop. When the cross bar 16 conflicts with the outer side of the notched ring 17, the movement of the notched ring 17 makes the cross bar 16 and the surface of the notched ring 17 slide relative to each other. When the left end of the notched ring 17 is against the stopper 21, with the movement of the turntable 2 and the pressure block 18, the third spring 19 on the left is compressed and the third spring 19 on the right is pulled, so that the turntable 2 can continue to rotate. When the turntable 2 swings to the left, the same principle is used above, so that the notched ring 17 cooperates with the inclined surface 20 to squeeze the right cross bar 16 to make it drop. With the movement of the notched ring 17, the inclined surface 20 at its left end is separated from the cross bar 16 on the left, and the squeezing of the left cross bar 16 is cancelled.

[0023] like Figures 2 to 3As shown, the collection assembly includes: a collection box 22, an opening opened at the top of the collection box 22, and a filter 23 disposed in the opening; The collecting box 22 is fixed to the front side of the machine body 1 , the bottom end of the suction tube 10 extends into the collecting box 22 , the opening is located at the bottom of the limiting column 3 , and an inclined drainage surface is provided at the bottom of the collecting box 22 .

[0024] The excess lubricating oil sliding down the surface of the limit column 3 falls on the surface of the filter screen 23, and enters the collection box 22 for recovery after being filtered. The inclined drainage surface guides the lubricating oil in the collection box 22 to the suction tube 10, making it easier for the suction tube 10 to extract the lubricating oil.

[0025] like Figure 4 As shown, the pulling assembly includes: an iron rod 24, an electromagnet 25; The iron rod 24 is fixedly connected to the bottom of the horizontal plate 5, and the electromagnet 25 is fixedly installed on the bottom wall of the groove.

[0026] The electromagnet 25 is powered on to become magnetic, so that the iron rod 24 is attracted to move it downward with the horizontal plate 5, and the first spring 6 is compressed to deform it to generate a force to move the horizontal plate 5 into the groove. The electromagnet 25 is powered off to lose its magnetism, and the compressed first spring 6 releases its force to move the horizontal plate 5 upward and back to its original position.

[0027] The technology for energizing and deenergizing the electromagnet 25 is based on the automation control technology in the prior art.

[0028] like Figure 4 As shown, the top curvature of the horizontal plate 5 is consistent with the curvature of the limiting column 3 , and the side of the horizontal plate 5 where the spray hole 7 is opened is located in the middle of the top end of the limiting column 3 .

[0029] After the transverse plate 5 is received in the groove, its surface will not protrude from the surface of the limiting column 3, thereby preventing the transverse plate 5 from scratching the cable.

[0030] like Figure 4 As shown, the conduit 9 is specifically configured as a hose.

[0031] When the horizontal plate 5 is lowered, the guide tube 9 can be adaptively extended and retracted.

[0032] The present invention also provides a method for testing using the above-mentioned cable production testing device, comprising the following steps: S1. When in use, the turntable 2 swings with the clamping assembly and the cable. When the turntable 2 and the cable swing to the right, the oil injection assembly is used to inject lubricating oil into the cavity in the horizontal plate 5 on the left limit column 3. The lubricating oil is sprayed onto the surface of the limit column 3 through the spray hole 7. The lubricating oil slides along the side of the limit column 3 close to the cable, so that the side of the limit column 3 close to the cable, i.e. the inner side, is lubricated; S2. At this time, the horizontal plate 5 on the right limit column 3 is pulled by the pulling component so that it is retracted into the groove, and at the same time, the first spring 6 is compressed to deform it to generate a force. At this time, the top of the right horizontal plate 5 and the surface of the limit column 3 form a complete cylindrical surface. By retracting the right horizontal plate 5, when the cable surface swings to the top position of the right limit column 3, it will not contact the horizontal plate 5, so that it will not be affected by the friction force caused by the contact between the horizontal plate 5 and the cable, thereby avoiding this part of the friction force affecting the accuracy of the detection result; S3, when the turntable 2 and the cable swing to the left, when the turntable 2 moves to reset, the pulling assembly on the right cancels the pulling on the cross plate 5, and the first spring 6 releases the force to lift the cross plate 5 to reset, and then the turntable 2 continues to swing to the left, so that the oil injection assembly injects lubricating oil into the cavity in the cross plate 5 located on the right limit column 3, and the lubricating oil is sprayed onto the surface of the limit column 3 through the spray hole 7, so that the limit column 3 on the right is lubricated, and at the same time, the pulling assembly drives the left cross plate 5 to be retracted into the groove, so as to avoid friction between the left cross plate 5 and the subsequent moving cable. Due to the lubrication of the left limit column 3, when the turntable 2 swings to the left with the cable, the friction between the cable and the left limit column 3 is low; S4. Subsequently, when the turntable 2 and the cable swing to the right, the limit column 3 on the left can continue to be lubricated as above. Similarly, because the limit column 3 on the right is lubricated, the friction between the cable and the limit column 3 on the right is low. Finally, the limit columns 3 on both sides are continuously lubricated during the swinging of the cable, so that the friction between the cable and the limit columns 3 on both sides is low, thereby avoiding the influence of excessive friction on the accuracy of the detection result. By continuously lubricating the limit columns 3, the lubricating oil on the surface of the limit columns 3 can be kept continuously when used under high air flow rate, so as to avoid the situation where the lubricating oil on the surface of the limit columns 3 is dried by air, thereby ensuring the lubrication effect.

[0033] Working principle: When in use, the turntable 2 swings with the clamping assembly and the cable. When the turntable 2 and the cable swing to the right, the pressure block 18 moves with it. The pressure block 18 cooperates with the third spring 19 to move with the notch ring 17. The notch ring 17 cooperates with the inclined surface 20 to squeeze the left cross bar 16 to make it descend, so that the push rod 13, the pressure plate 14, and the piston 12 descend. The pressure plate 14 compresses the second spring 15 to deform it and generate a force. As the piston 12 descends, the lubricating oil in the cylinder 8 is squeezed outward. At this time, the one-way valve 11 in the suction tube 10 is closed, and the lubricating oil enters the cavity through the conduit 9. Then, the one-way valve 11 is pushed open through the spray hole 7 and sprayed to the surface of the limit column 3. The lubricating oil slides along the side of the limit column 3 close to the cable. The side of the limit column 3 close to the cable, that is, the inner side, is lubricated. At this time, the electromagnet 25 on the right side is energized to make it magnetic, so that the iron rod 24 is attracted to make it descend with the cross plate 5, and at the same time, the first spring 6 is compressed to deform it to generate a force, so as to realize the collection of the right cross plate 5 into the groove, so that when the cable surface swings to the top position of the right limit column 3, it will not contact the cross plate 5, so that it will not be affected by the friction force caused by the contact between the cross plate 5 and the cable, so as to avoid this part of the friction force affecting the accuracy of the detection result. When the cross bar 16 contacts the outer side of the notched ring 17, at this time, with the movement of the notched ring 17, the cross bar 16 and the surface of the notched ring 17 slide relative to each other. When the left end of the notched ring 17 contacts the stopper 21, at this time, with the rotation The movement of the disk 2 and the pressure block 18 compresses the third spring 19 on the left and pulls the third spring 19 on the right, so that the turntable 2 can continue to rotate. When the turntable 2 and the cable swing to the left, when the turntable 2 moves to reset, the electromagnet 25 on the right is powered off to make it magnetic, and the compressed first spring 6 releases the force to lift the cross plate 5 to reset. Then the turntable 2 and the cable continue to swing to the left, and the electromagnet 25 on the left is energized, so that the cross plate 5 on the left is retracted into the groove, so as to avoid friction between the cross plate 5 on the left and the subsequent moving cable. At the same time, with the movement of the notch ring 17, the inclined surface 20 at its right end squeezes the cross bar 16 on the right, so that the lubrication of the right limit column 3 is achieved in the same way as the above principle. The lubrication of the limit posts 3 on both sides is finally achieved during the swinging process of the cable, so that the friction between the cable and the limit posts 3 on both sides is low, thereby avoiding the influence of excessive friction on the accuracy of the detection result. By continuously lubricating the limit posts 3, the lubricating oil on the surface of the limit posts 3 can be kept continuously when used under the condition of high air flow rate, so as to avoid the situation that the lubricating oil on the surface of the limit posts 3 is dried by air, thereby ensuring the lubrication effect.The excess lubricating oil sliding down the surface of the limit column 3 falls on the surface of the filter screen 23, and enters the collection box 22 after being filtered to complete recycling. The inclined drainage surface guides the lubricating oil in the collection box 22 to the suction pipe 10, making it easy for the suction pipe 10 to extract the lubricating oil. By filtering the lubricating oil before recycling, it is possible to prevent impurities from entering the spray hole 7 along with the lubricating oil and clogging the spray hole 7.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.

7. The cable production and testing equipment according to claim 6, characterized in that: The conduit (9) is specifically configured as a hose.

8. A method for testing using the cable production testing device according to claim 7, characterized in that: The steps include: S1. When in use, the turntable (2) is swung with the clamping assembly and the cable. When the turntable (2) and the cable swing to the right, the oil injection assembly is used to inject lubricating oil into the cavity in the horizontal plate (5) on the left limit column (3). The lubricating oil is sprayed onto the surface of the limit column (3) through the spray hole (7). The lubricating oil slides along the side of the limit column (3) close to the cable, so that the side of the limit column (3) close to the cable, i.e., the inner side, is lubricated. S2. At this time, the horizontal plate (5) on the right limit column (3) is pulled by the pulling component so that it is retracted into the groove, and at the same time, the first spring (6) is compressed to deform it and generate a force. At this time, the top of the right horizontal plate (5) and the surface of the limit column (3) form a complete cylindrical surface. By retracting the right horizontal plate (5), when the cable surface swings to the top position of the right limit column (3), it will not contact the horizontal plate (5), so that the cable will not be affected by the friction force caused by the contact between the horizontal plate (5) and the cable, thereby avoiding this part of the friction force affecting the accuracy of the detection result; S3, when the turntable (2) and the cable swing to the left, when the turntable (2) moves to reset, the pulling component on the right side cancels the pulling on the horizontal plate (5), the first spring (6) releases the force and brings the horizontal plate (5) up to reset, and then the turntable (2) continues to swing to the left, so that the oil injection component injects lubricating oil into the cavity in the horizontal plate (5) located on the right limit column (3), and the lubricating oil is sprayed onto the surface of the limit column (3) through the spray hole (7), so that the limit column (3) on the right is lubricated, and at the same time, the pulling component drives the horizontal plate (5) on the left side to be retracted into the groove, so as to avoid friction between the horizontal plate (5) on the left side and the subsequent moving cable. Due to the lubrication of the limit column (3) on the left side, when the turntable (2) swings to the left with the cable, the friction between the cable and the limit column (3) on the left side is low; S4. Subsequently, when the turntable (2) and the cable swing to the right, the limit column (3) on the left can continue to be lubricated. Similarly, because the limit column (3) on the right is lubricated, the friction between the cable and the limit column (3) on the right is low. Finally, the limit columns (3) on both sides are continuously lubricated during the swinging of the cable, so that the friction between the cable and the limit columns (3) on both sides is low, thereby avoiding the influence of excessive friction on the accuracy of the detection result. By continuously lubricating the limit column (3), when used under the condition of high air flow rate, the lubricating oil on the surface of the limit column (3) can be kept continuously, so as to avoid the situation that the lubricating oil on the surface of the limit column (3) is dried by air, thereby ensuring the lubrication effect.
