Description

Technical Field

[0001] This invention relates to the field of cable testing technology, and in particular to a multifunctional cable sampling machine. Background Technology

[0002] In cable testing, the outer sheath of the cable needs to be inspected. During the inspection, two types of samples of the outer sheath need to be obtained: a side sample and a radial sample. Specifically, the side sample is obtained by cutting along the extension direction of the cable on one side with a blade, while the radial sample is obtained by cutting perpendicular to the extension direction of the cable at the end with a blade. Existing sampling machines often can only obtain one type of sample, either side or radial, which is a single function. Summary of the Invention

[0003] To address the shortcomings of existing sampling machines that can only obtain side or radial samples and have limited functionality, this invention proposes a multifunctional cable sampling machine that can obtain both side and radial samples.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional cable sampling machine includes a base, a first sliding seat, a second sliding seat, a third sliding seat disposed between the first and second sliding seats, a first fixing device for clamping the cable disposed on the upper side of the first sliding seat, a second fixing device for clamping the cable disposed on the upper side of the third sliding seat, a pressing column fixedly connected to the side of the second sliding seat near the third sliding seat, a lifting plate disposed above the base, a first driving device for driving the lifting plate to move up and down, a ring blade fixedly connected to the lower side of the lifting plate, a bracket fixedly connected to the lower side of the lifting plate, and a blade rotatably connected to the bracket. The blade has a through hole, extends horizontally, and has cutting edges at both ends. The cable includes a conductor and an outer sheath wrapped around the conductor. The base is provided with a second driving device for driving the first and second sliding seats to move, and the lifting plate is provided with a third driving device for driving the blade to rotate. The diameter of the through hole is adapted to the outer diameter of the conductor, the outer diameter of the pressing column is adapted to the outer diameter of the conductor, and the third sliding seat is connected to the first sliding seat through an elastic element.

[0005] With the above setup, this application can obtain side and radial samples with high efficiency. Specifically, the cable is placed on the first and third sliding seats, with one end of the cable flush with the end of the third sliding seat closest to the second sliding seat. The first fixing device clamps the cable and fixes it on the first sliding seat, and the second fixing seat clamps the cable and fixes it on the third sliding seat. The third driving device rotates the blade, causing it to extend vertically. At this time, the cutting edge is located at the upper and lower ends of the blade. Under the action of the first driving device, the lifting plate moves downward, and the cutting edge cuts the cable. At this time, the blade is located between the third and first sliding seats, and the position of the through hole and the cable wire on the left corresponds. Then, the second driving device drives the second and first sliding seats to move to the right. The blade obstructs the third sliding seat from moving to the right, causing the elastic element to extend. The second sliding seat drives the extrusion column to move to the right and extrudes the cable wire on the left side of the blade. The wire is extruded to the right and passes through the through hole. The extrusion column inserts into the outer sheath of the cable located on the left side of the blade. Then, the lifting plate moves upward, and the blade leaves the cable. Under the action of the elastic element, the third sliding seat moves to the right, and the left wire and the right cable come into contact. The left outer sheath and the extrusion column separate. Then, the second drive device drives the first and second sliding seats to move along the base, so that the blade is located above the left outer sheath near the end of the extrusion column. Then, the lifting plate moves downward and cuts off the left end of the left outer sheath to obtain a radial sample.

[0006] Then, the second fixing device is loosened, and the cable on the third sliding seat is removed. The blade is then rotated 90 degrees, causing it to extend horizontally. At this point, the cable on the first sliding seat is located on the right side of the blade, and the ring cutter is located on the left side of the blade. The lower edge of the ring cutter is at a higher height than the blade. Under the action of the second driving device, the first and third sliding seats move to the left. When the cable passes the blade, the upper side of the outer sheath is cut by the blade to form a flat cutting surface. When the cable moves to the lower side of the ring cutter, the lifting plate moves downward, and the ring cutter cuts an annular groove on the cutting surface. Then, the lifting plate moves upward, causing the ring cutter and the cable to separate. Then, the second driving device drives the first sliding seat to move to the right, and the upper side of the outer sheath is cut again from right to left. The cutting depth is less than the depth of the annular groove, so that when the blade passes through the annular groove, the blade cuts a sample piece from the lower side of the outer sheath.

[0007] Furthermore, there are two supports, with the blade positioned between them. Rotary shafts are fixedly connected to the opposite sides of the blades, passing through and rotatably connecting to the supports. The blades are rotatably connected to the supports via the rotating shafts.

[0009] Furthermore, a top plate is provided above the base, and the first driving device includes a first lead screw extending vertically and a first motor mounted on the base. The upper end of the first lead screw is rotatably connected to the top plate, the lower end of the first lead screw is connected to the first motor, and the first lead screw passes through the lifting plate and is threadedly connected to the lifting plate.

[0010] Furthermore, a support plate is fixedly connected to one end of the base. The second driving device includes a second lead screw extending horizontally and a second motor mounted on the base. The second motor is connected to the second lead screw and is used to drive the second lead screw to rotate around the axis of the second lead screw.

The second lead screw passes through the first sliding seat, the clearance hole, and the second sliding seat. The second lead screw and the first sliding seat are threadedly connected. The second lead screw and the second sliding seat are threadedly connected.

[0011] Furthermore, a first limiting plate and a second limiting plate are fixedly connected to the side of the first sliding seat near the third sliding seat. The first limiting plate and the third sliding seat abut against each other. The second limiting plate is positioned above the first limiting plate. The second limiting plate and the third sliding seat are in clearance fit. A notch for the blade to pass through is formed between the second limiting plate and the third sliding seat. A receiving groove with an opening facing the third sliding seat is formed between the first limiting plate, the second limiting plate, and the first sliding seat. A guide rod is fixedly connected to the side of the first sliding seat near the third sliding seat. The third sliding seat is provided with a guide groove with an opening facing the first sliding seat. One end of the guide rod is fixedly connected to the first sliding seat. The guide rod is inserted into the guide groove and slidably connected to the guide groove. The elastic element includes a spring sleeved on the guide rod. One end of the spring is connected to the first sliding seat, and the other end of the spring is connected to the third sliding seat.

[0012] Furthermore, the first fixing device includes two first clamping members disposed on the upper side of the first sliding seat. A first fixing seat is disposed on the side of the first clamping member away from the other first clamping member. The first fixing seat and the first sliding seat are fixedly connected.

[0028] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0029] See Figures 1 to 14 A multifunctional cable sampling machine includes a base 11, a first sliding seat 12, a second sliding seat 13, a third sliding seat 14 disposed between the first sliding seat 12 and the second sliding seat 13, a first fixing device 121 for clamping a cable 21 disposed on the upper side of the first sliding seat 12, a second fixing device 141 for clamping the cable 21 disposed on the upper side of the third sliding seat 14, a pressing column 131 fixedly connected to the side of the second sliding seat 13 near the third sliding seat 14, a lifting plate 15 disposed above the base 11, a first driving device 18 for driving the lifting plate 15 to move up and down, a ring cutter 151 fixedly connected to the lower side of the lifting plate 15, and a ring cutter 151 fixedly connected to the lifting plate 15. The lower side of the 5 has a bracket 152, a blade 153 rotatably connected to the bracket 152, and a through hole 1531 provided in the blade 153. The blade 153 extends horizontally and has blades at both ends. The cable 21 includes a conductor 211 and an outer sheath 212 wrapped around the conductor 211. The base 11 is provided with a second driving device 16 for driving the first sliding seat 12 and the second sliding seat 13 to move. The lifting plate 15 is provided with a third driving device for driving the blade 153 to rotate. The diameter of the through hole 1531 is adapted to the outer diameter of the conductor 211. The outer diameter of the extrusion column 131 is adapted to the outer diameter of the conductor 211. The third sliding seat 14 is connected to the first sliding seat 12 through an elastic member 142.

[0030] With the above setup, this application can obtain side sample 31 and radial sample 41, and the work efficiency is high. Specifically, the cable 21 is placed on the first sliding seat 12 and the third sliding seat 14, with one end of the cable 21 flush with the end of the third sliding seat 14 near the second sliding seat 13. The first fixing device 121 clamps the cable 21 and fixes the cable 21 on the first sliding seat 12, and the second fixing seat 1412 clamps the cable 21 and fixes the cable 21 on the third sliding seat 14. See [link to documentation]. Figure 5 The third drive device rotates the blade 153, causing the blade 153 to extend vertically. At this time, the cutting edge is located at the upper and lower ends of the blade 153. (See above) Figure 6Under the action of the first driving device 18, the lifting plate 15 moves downward, and the blade cuts the cable 21. At this time, the blade 153 is located between the third sliding seat 14 and the first sliding seat 12, and the position of the through hole 1531 corresponds to the position of the wire 211 of the cable 21 on the left side. Then, the second driving device 16 drives the second sliding seat 13 and the first sliding seat 12 to move to the right. The blade 153 obstructs the third sliding seat 14 from moving to the right, and the elastic element 142 extends. The second sliding seat 13 drives the extrusion column 131 to move to the right and extrudes the wire 211 of the cable 21 on the left side of the blade 153. The wire 211 is extruded to the right and passes through the through hole 1531. The extrusion column 131 is inserted into the outer sheath 212 of the cable 21 located on the left side of the blade 153. See Figure 7 Then, the lifting plate 15 moves upward, the blade 153 leaves the cable 21, and under the action of the elastic element 142, the third sliding seat 14 moves to the right, the left wire 211 and the right cable 21 abut, and the left outer sheath 212 and the extrusion column 131 disengage. Then, the second driving device 16 drives the first sliding seat 12 and the second sliding seat 13 to move along the base 11, so that the blade 153 is located above the end of the left outer sheath 212 near the extrusion column 131. Then, the lifting plate 15 moves downward and cuts off the left end of the left outer sheath 212 to obtain the radial sample 41. See Figure 8 .

[0031] Then the second fixing device 141 is loosened, and the cable 21 on the third sliding seat 14 is removed. The blade 153 is then rotated ninety degrees, causing it to extend horizontally. (See attached image.) Figure 9 At this time, the cable 21 on the first sliding seat 12 is located to the right of the blade 153, and the ring cutter 151 is located to the left of the blade 153. The lower edge of the ring cutter 151 is at a higher height than the blade 153. Under the action of the second driving device 16, the first sliding seat 12 and the third sliding seat 14 move to the left. When the cable 21 passes the blade 153, the upper side of the outer sheath 212 is cut by the blade 153 to form a flat cutting surface. (See [reference]). Figure 10 When the cable 21 moves to the underside of the ring cutter 151, the lifting plate 15 moves downward, and the ring cutter 151 cuts an annular groove on the cutting surface. (See below) Figure 11 and Figure 12 Then, the lifting plate 15 moves upward, causing the ring cutter 151 and the cable 21 to disengage. Then, the second drive device 16 drives the first sliding seat 12 to move to the right, and the upper side of the outer sheath 212 cuts again from right to left. The cutting depth is less than the depth of the annular groove, so that when the blade 153 passes through the annular groove, the blade 153 cuts the lower sample piece 31 from the outer sheath 212. (See...) Figure 13 and Figure 14 .

[0032] In one implementation, there are two supports 152, and the blades 153 are arranged between the supports 152. The opposite sides of the blades 153 are fixedly connected to the rotating shafts 1532. The rotating shafts 1532 pass through the supports 152 and are rotatably connected to the supports 152. The blades 153 are rotatably connected to the supports 152 through the rotating shafts 1532.

[0033] In one implementation, a first rotating rod 1533 is fixedly connected to a rotating shaft 1532, and a second rotating rod 1534 is rotatably connected to the end of the first rotating rod 1533 away from the rotating shaft 1532. The third driving device includes an electric cylinder 1535 mounted on a lifting plate 15, and the output shaft of the electric cylinder 1535 is rotatably connected to the end of the second rotating rod 1534 away from the first rotating rod 1533.

[0034] Through the above settings, the blade 153 is rotated. Specifically, when the electric cylinder 1535 extends or retracts, the electric cylinder 1535 drives the blade 153 to rotate around the axis of the rotating shaft 1532 through the second rotating rod 1534 and the rotating shaft 1532.

[0035] In one implementation, a top plate 17 is provided above the base 11. The first driving device 18 includes a first lead screw 181 extending vertically and a first motor provided on the base 11. The upper end of the first lead screw 181 is rotatably connected to the top plate 17, and the lower end of the first lead screw 181 is connected to the first motor. The first lead screw 181 passes through the lifting plate 15 and is threadedly connected to the lifting plate 15.

[0036] With the above settings, the lifting plate 15 can move up and down. When the first motor drives the first lead screw 181 to rotate around the first lead screw 181, the first lead screw 181 and the lifting plate 15 rotate relative to each other, and the lifting plate 15 moves up and down along the axis of the first lead screw 181.

[0037] In one implementation, a support plate 111 is fixedly connected to one end of the base 11. The second driving device 16 includes a second lead screw 161 extending horizontally and a second motor 162 mounted on the base 11. The second motor 162 is connected to the second lead screw 161 and is used to drive the second lead screw 161 to rotate around the axis of the second lead screw 161. The second lead screw 161 is rotatably connected to the support plate 111. The third sliding seat 14 is provided with a clearance hole 143. The second lead screw 161 passes through the first sliding seat 12, the clearance hole 143, and the second sliding seat 13. The second lead screw 161 is threadedly connected to the first sliding seat 12, and the second lead screw 161 is threadedly connected to the second sliding seat 13.

[0038] With the above settings, the movement of the first sliding seat 12 and the second sliding seat 13 is realized. When the second motor 162 drives the second lead screw 161 to rotate around the axis of the second lead screw 161, the second lead screw 161 and the first sliding seat 12 rotate relative to each other. The first sliding seat 12 moves on the base 11 along the axis of the second lead screw 161. At the same time, the second lead screw 161 and the second sliding seat 13 rotate relative to each other. The second sliding seat 13 moves on the base 11 along the axis of the second lead screw 161. When the second motor 162 is running, the first sliding seat 12 and the second sliding seat 13 move in the same direction and at the same speed.

[0039] In one implementation, a first limiting plate 122 and a second limiting plate 123 are fixedly connected to the side of the first sliding seat 12 near the third sliding seat 14. The first limiting plate 122 abuts against the third sliding seat 14, and the second limiting plate 123 is positioned above the first limiting plate 122. The second limiting plate 123 and the third sliding seat 14 are in clearance fit, and a notch 124 for the blade 153 to pass through is formed between the second limiting plate 123 and the third sliding seat 14. An opening is formed between the first limiting plate 122, the second limiting plate 123, and the first sliding seat 12. The receiving groove 125 faces the third sliding seat 14. A guide rod 126 is fixedly connected to the side of the first sliding seat 12 near the third sliding seat 14. The third sliding seat 14 is provided with a guide groove 144 with an opening facing the first sliding seat 12. One end of the guide rod 126 is fixedly connected to the first sliding seat 12. The guide rod 126 is inserted into the guide groove 144 and slidably connected with the guide groove 144. The elastic element 142 includes a spring sleeved on the guide rod 126. One end of the spring is connected to the first sliding seat 12, and the other end of the spring is connected to the third sliding seat 14.

[0040] With the above settings, initially, under the action of the spring, the third sliding seat 14 is pressed against the first limiting plate 122, so that when the second motor 162 runs, the third sliding seat 14 and the first sliding seat 12 move synchronously. The clearance hole 143 is used to avoid the second lead screw 161. When the blade 153 cuts the cable 21 downwards, the lower end of the blade 153 inserts into the notch 124, so that the through hole 1531 and the wire 211 on the left side of the blade 153 correspond. When the second driving device 16 drives the first sliding seat 12 and the second sliding seat 13 to move to the right, the spring lengthens, and the extrusion column 131 extrudes the wire 211 to the right and inserts it into the left end of the outer sheath 212 to facilitate the cutting of the radial sample 41. See Figure 7 When the blade 153 moves upward, the spring contracts, the third sliding seat 14 moves to the right, and the conductor 211 of the left cable 21 and the right cable 21 come into contact. (See below) Figure 8 The axis of the guide rod 126 is parallel to the axis of the second lead screw 161, so that when the spring extends or retracts, the third sliding seat 14 moves in the axial direction of the second lead screw 161.

[0041] In one implementation, the first fixing device 121 includes two first clamping members 1211 disposed on the upper side of the first sliding seat 12. A first fixing seat 1212 is disposed on the side of the first clamping member 1211 away from the other first clamping member 1211. The first fixing seat 1212 is fixedly connected to the first sliding seat 12. The extension direction of the first clamping member 1211 is consistent with the extension direction of the second lead screw 161. A first locking bolt 1213 passes through the first fixing seat 1212. The first locking bolt 1213 passes through the first fixing seat 1212 and is threadedly connected to the first fixing seat 1212. The first locking bolt 1213 is rotatably connected to the first clamping member 1211. The end of the first clamping member 1211 near the third sliding seat 14 is flush with the end of the second limiting plate 123 near the third sliding seat 14.

[0042] With the above configuration, it is convenient to fix the cable 21 on the upper side of the first sliding seat 12. Specifically, after the cable 21 is placed between the first clamping members 1211, the first locking bolt 1213 is rotated. The first locking bolt 1213 and the first fixing seat 1212 rotate relative to each other. The first locking bolt 1213 drives the first clamping member 1211 to move toward the cable 21. When the first clamping member 1211 clamps the cable 21, the cable 21 is fixed on the first sliding seat 12.

[0043] In one implementation, the second fixing device 141 includes two second clamping members 1411 disposed on the upper side of the third sliding seat 14. A second fixing seat 1412 is disposed on the side of the second clamping member 1411 away from the other second clamping member 1411. The second fixing seat 1412 is fixedly connected to the second sliding seat 13. The extension direction of the second clamping member 1411 is consistent with the extension direction of the second lead screw 161. A second locking bolt 1413 passes through the second fixing seat 1412. The second locking bolt 1413 passes through the second fixing seat 1412 and is threadedly connected to the second fixing seat 1412. The second locking bolt 1413 is rotatably connected to the second clamping member 1411. The end of the second clamping member 1411 near the first sliding seat 12 is flush with the end of the third sliding seat 14 near the first sliding seat 12.

[0044] With the above configuration, it is convenient to fix the cable 21 on the upper side of the second sliding seat 13. Specifically, after the cable 21 is placed between the second clamping members 1411, the second locking bolt 1413 is rotated. The second locking bolt 1413 and the second fixed seat 1412 rotate relative to each other. The second locking bolt 1413 drives the second clamping member 1411 to move toward the cable 21. When the second clamping member 1411 clamps the cable 21, the cable 21 is fixed on the second sliding seat 13.
