Description

Technical Field

[0001] This invention belongs to the field of handle cable manufacturing technology, and particularly relates to a wire core insertion device for handle cable manufacturing. Background Technology

[0002] Handle cable, also known as pull cable, control cable or push-pull cable, is a flexible mechanical transmission device widely used in automobiles. Its core function is to transmit the driver's operation (such as pulling or pushing) or the action of the actuator to the other end through a curved path, thereby controlling various functions. However, in the current manufacturing of handle cables, only one set of sheaths and wire cores can be inserted and assembled at a time, which is inefficient.

[0003] For example, Chinese patent application number CN202111193309.3 discloses a wire core insertion device for automotive cable manufacturing, which includes a base, a mounting plate, a control plate, an LCD display screen, a first reduction motor, a friction roller, a pressing mechanism, and an alignment mechanism. The mounting plate is provided on one side of the top of the base, and a control box is provided on one side of the mounting plate. The control plate is provided on the side of the top of the mounting plate close to the control box. An LCD display screen is provided on one side of the upper part of the control plate, and a pressing mechanism is provided on the side of the top of the mounting plate away from the mounting plate. However, the disadvantage of this technical solution is that it can only perform the insertion and assembly of one set of wire tubes and wire cores at a time, which is slow and has a low degree of automation. Summary of the Invention

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figures 1-15 As shown, a wire core insertion device for manufacturing a handle cable includes a base 6, a sheath clamping assembly 1 fixed on the base 6, the sheath clamping assembly 1 clamps four sheaths 4 at equal intervals around the circumference, and an insertion auxiliary assembly 2 and a wire core feeding assembly 3 are slidably connected on the base 6. The wire core feeding assembly 3 inserts the four wire cores 5 into the four sheaths 4 respectively through the insertion auxiliary assembly 2.

[0038] The working principle of the above technical solution is as follows: the sheath clamping component 1 can clamp and fix four sheaths 4 at the same time, the insertion auxiliary component 2 slides forward on the base 6 and is sleeved on the ends of the four sheaths 4, the wire core feeding component 3 can move the four wire cores 5 forward at the same time, the front end of the wire core 5 is inserted into the insertion auxiliary component 2, and under the action of the insertion auxiliary component 2, the four wire cores 5 are accurately inserted into the four sheaths 4, realizing the simultaneous manufacturing of four sets of handle cables and improving the manufacturing efficiency of handle cables.

[0039] Example 2

[0040] like Figures 1-15 As shown, the base 6 is fixedly connected to the cylinder 8, the output end of the cylinder 8 is connected to the wire feeding assembly 3, a spring 7 is provided between the insertion auxiliary assembly 2 and the wire feeding assembly 3, and a cutting assembly 9 is provided inside the wire feeding assembly 3.

[0041] The working principle of the above technical solution is as follows: Four sheaths 4 are fixed inside the sheath clamping assembly 1, and four wire cores 5 are inserted into the wire core feeding assembly 3. The wire core feeding assembly 3 moves the four wire cores 5 forward simultaneously. When the front ends of the four wire cores 5 are exposed at the front end of the wire core feeding assembly 3, the cylinder 8 is activated, which drives the insertion auxiliary assembly 2 and the wire core feeding assembly 3 to move forward on the base 6. The insertion auxiliary assembly 2 is sleeved on the ends of the four sheaths 4. The insertion auxiliary assembly 2 can no longer move forward. The wire core feeding assembly 3 moves forward and compresses the spring 7. The front ends of the four wire cores 5 are inserted into the insertion auxiliary assembly 2. Under the action of the insertion auxiliary assembly 2, the four wire cores 5 are accurately inserted into the four sheaths 4, realizing the simultaneous manufacturing of four sets of handle cables and improving the manufacturing efficiency of handle cables.

[0042] Example 3

[0043] like Figures 1-15 As shown, the sheath clamping assembly 1 includes a bracket 105, which is fixed on the base 6. The bracket 105 is sleeved on both ends of the outer shaft 101. The protrusion 108 provided at the end of the outer shaft 101 is engaged in the groove 1 on the bracket 105, and a gap is left between the protrusion 108 and the groove 1.

[0044] The outer shaft 101 is fixedly connected to four stationary clamps 102. An inner shaft 103 is rotatably connected inside the outer shaft 101. The inner shaft 103 is fixedly connected to four movable clamps 104. The sheath 4 is clamped between the stationary clamps 102 and the movable clamps 104. The stationary clamps 102 are fixedly connected to a motor 106. The output end of the motor 106 is connected to the inner shaft 103. Protective pads 107 are provided inside both the stationary clamps 102 and the movable clamps 104.

[0045] The working principle of the above technical solution is as follows: The starting motor 106 drives the inner shaft 103 to rotate, which in turn drives the four moving clamps 104 to rotate. The moving clamps 104 separate from the stationary clamps 102, and the sheath 4 is placed between the moving clamps 104 and the stationary clamps 102. The motor 106 then drives the inner shaft 103 to rotate in the opposite direction, which in turn drives the four moving clamps 104 to rotate in the opposite direction. The moving clamps 104 and the stationary clamps 102 tighten the sheath 4.

[0046] The protective pad 107 prevents the sheath 4 from slipping when it is fitted with the wire core 5;

[0047] Since the protrusion 108 at the end of the outer shaft 101 is engaged in the groove 1 on the bracket 105, and there is a gap between the protrusion 108 and the groove 1, the sheath 4 can swing slightly to the left or right, which makes it convenient for the sheath 4 to be sleeved with the insertion auxiliary component 2.

[0048] Example 4

[0049] like Figures 1-15 As shown, the insertion auxiliary component 2 includes a second bracket 201, which slides on the base 6. The second bracket 201 is fixedly connected to the slide rod 202, and the slide rod 202 is slidably connected to the wire core feeding component 3. A first spring 7 is sleeved on the outside of the slide rod 202 and is located between the second bracket 201 and the wire core feeding component 3. The second bracket 201 is sleeved on both ends of the four-leaf frame 203. A second protrusion 211 provided at the end of the four-leaf frame 203 is engaged in the second groove on the four-leaf frame 203, and a gap is left between the second protrusion 211 and the second groove.

[0050] The four-leaf frame 203 is fixedly connected to four connecting cylinders 204. Both ends of the connecting cylinders 204 are provided with tapered openings. The connecting cylinders 204 are fixedly connected to the elastic sheet 205. The connecting cylinders 204 are provided with an annular chamber 206. The annular chamber 206 is connected to the outside through four sets of discharge holes 207. The annular chamber 206 is connected to the material distribution bin 209 provided in the four-leaf frame 203 through the flow channel 208. The material distribution bin 209 is connected to the feed pipe 210.

[0051] The working principle of the above technical solution is as follows: After the four sheaths 4 are fixed on the sheath clamping assembly 1, the cylinder 8 is activated, which drives the wire core feeding assembly 3 to move forward on the base 6. Through the spring 7, the bracket 201 moves forward on the base 6, which in turn drives the four-leaf frame 203 and the four connecting cylinders 204 to move forward with the bracket 201. The front end of the sheath 4 is inserted into the connecting cylinder 204 through the tapered opening at the end of the connecting cylinder 204. The elastic sheet 205 is inserted into the sheath 4. The core feeding assembly 3 continues to move forward on the base 6. The four cores 5 that are removed from the core feeding assembly 3 are respectively inserted into the four connecting cylinders 204. The grease is fed into the distribution bin 209 through the feed pipe 210, and then into the four annular chambers 206 through the four flow channels 208. It is then coated on the outer surface of the four cores 5 through the four sets of discharge holes 207. The four cores 5 pass through the connecting cylinders 204. The outer surface of the cores 5 is coated with grease, which makes it easy to insert into the sheath 4.

[0052] When the wire core 5 passes through the connecting cylinder 204, the wire core 5 is deformed by squeezing the elastic sheet 205, and the front end of the wire core 5 directly enters the sheath 4. The function of the elastic sheet 205 is to guide the wire core 5 into the sheath 4 and prevent the end of the wire core 5 from getting stuck at the end of the sheath 4.

[0053] After the wire core 5 is inserted into the sheath 4, the cylinder 8 is activated, which moves the wire core feeding assembly 3 backward. The spring force of the spring 7 is released, and the tail of the wire core 5 is disengaged from the wire core feeding assembly 3. The wire core feeding assembly 3 continues to move backward, and the spring 7 pulls the bracket 201 backward, which in turn moves the four-leaf bracket 203 and the four connecting cylinders 204 backward. The tail of the wire core 5 slides with the connecting cylinder 204 until the tail of the wire core 5 separates from the connecting cylinder 204. The motor 106 is activated, which drives the inner shaft 103 to rotate, which in turn drives the four moving clamps 104 to rotate. The moving clamps 104 separate from the stationary clamps 102, and the inserted sheath 4 and wire core 5 are taken out for the next step of processing. The overall wire core 5 insertion process is highly automated.

[0054] Example 5

[0055] like Figures 1-15 As shown, the wire core feeding assembly 3 includes a housing 301, which slides on the base 6. The housing 301 is connected to a cylinder 8, and a slide rod 202 is slidably connected to the housing 301. A spring 7 is disposed between a bracket 201 and the housing 301. The housing 301 is fixedly connected to a motor 302. The output end of the motor 302 is connected to a gear 303. The gear 303 meshes with a gear 304 for transmission. The gear 304 is fixedly connected to a connecting column 305. The connecting column 305 rotates within the housing 301. Wire core feeding units are provided at both ends of the connecting column 305. A cutting assembly 9 is located between the two wire core feeding units and is slidably connected within the housing 301.

[0056] The working principle of the above technical solution is as follows: Four wire cores 5 are inserted into the rear end of the housing 301. The second motor 302 is started, which drives the first gear 303 to rotate, drives the second gear 304 to rotate, drives the connecting column 305 to rotate, and drives the two wire core feeding units to operate simultaneously, moving the four wire cores 5 forward at the same time. When the wire cores 5 have been moved out of the preset distance, the second motor 302 stops working, the cutting component 9 cuts the wire cores 5, the second motor 302 starts, and the wire core feeding unit at the front end moves the wire cores 5 at the front end of the cutting component 9 out of the housing 301, completing the insertion and assembly of the sheath 4 and the wire cores 5. The wire core feeding unit at the rear end continues to move the wire cores 5 at the rear end of the cutting component 9 forward, the wire cores 5 move into the wire core feeding unit at the front end, and move out of the housing 301, and are inserted into the next batch of sheaths 4. This realizes that the insertion and assembly of the sheath 4 and the wire cores 5 and the cutting of the wire cores 5 are carried out without interruption, with a high degree of automation.

[0057] Example 6

[0058] like Figures 1-15 As shown, the wire core feeding unit includes a central bevel gear 306, which meshes with four bevel gears 307 for transmission. The bevel gears 307 are fixedly connected to gears 308. The fixed connection between the bevel gears 307 and gears 308 rotates within the housing 301. Gears 308 mesh with gears 309 for transmission. Gears 309 are fixedly connected to the drive wheel 310. Both the upper and lower ends of the drive wheel 310 rotate within the housing 301. The wire core 5 moves forward between the drive wheel 310 and the driven wheel 311. The driven wheel 311 rotates within the driven wheel bracket 312.

[0059] The driven wheel bracket 312 is slidably connected to the housing 301, the driven wheel bracket 312 is slidably connected to the slide plate 314, a second spring 313 is provided between the driven wheel bracket 312 and the slide plate 314, the front end of the screw 315 passes through the second spring 313 and is rotatably connected to the slide plate 314, and the screw 315 is threadedly connected to the housing 301.

[0060] The working principle of the above technical solution is as follows: Starting motor 2 302 drives gear 1 303 to rotate, drives gear 2 304 to rotate, drives connecting column 305 to rotate, drives central bevel gear 306 to rotate, drives four bevel gears 2 307 to rotate, drives four gears 308 to rotate, drives four gears 4 309 and drive wheel 310 to rotate, thereby driving the four wire cores 5 to move forward in the housing 301. Only one power source is needed to drive the four wire cores 5 to move forward in the housing 301 at the same time, saving energy and making control convenient.

[0061] Under the tension of spring 313, the driven wheel bracket 312 exerts a force towards the wire core 5, causing the driven wheel 311 to press tightly against the side of the wire core 5. This causes the driving wheel 310 and the driven wheel 311 to tighten the wire core 5. When the driving wheel 310 rotates, it drives the wire core 5 to move forward steadily. Rotating the screw 315 causes the slide plate 314 to slide on the housing 301, which in turn drives the elastic force of spring 313, changing the tightening force of the driven wheel 311 on the wire core 5. This allows for the stable transfer of wire cores 5 of different diameters by adjusting the screw 315.

[0062] Example 7

[0063] like Figures 1-15 As shown, the cutting assembly 9 includes a second cylinder 901, which is fixed on the outer wall of the housing 301. The output end of the second cylinder 901 is fixedly connected to the support frame 902. The support frame 902 is fixedly connected to four triangular sliders 903. The four triangular sliders 903 slide on the housing 301. The triangular sliders 903 are slidably connected to the lower end of the cutter 904. The cutter 904 slides inside the housing 301. A third spring 905 is provided between the cutter 904 and the housing 301.

[0064] The working principle of the above technical solution is as follows: Four wire cores 5 are inserted into the rear end of the housing 301. The second motor 302 is started, which drives the first gear 303 to rotate, drives the second gear 304 to rotate, drives the connecting column 305 to rotate, and drives the two wire core feeding units to operate simultaneously, moving the four wire cores 5 forward at the same time. When the wire cores 5 have been moved out of the preset distance, the second motor 302 stops working, and the second cylinder 901 is started, which drives the support frame 902 to move forward, causing the four triangular sliders 903 to slide forward in the housing 301, driving the four cutting... The lower end of the blade 904 slides with four triangular sliders 903 respectively. The upper ends of the four blades 904 cut the four wire cores 5 respectively. The motor 302 is started. The wire core feeding unit at the front end moves the wire core 5 out of the housing 301 and assembles it with the current sheath 4. The wire core feeding unit at the rear end moves the wire core 5 into the next batch of sheaths. When the wire core 5 has been moved out of the preset distance, it is cut again by the blade 904. The assembly of the sheath 4 and the wire core 5 and the cutting of the wire core 5 are carried out continuously, with a high degree of automation.
