Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and particularly relates to a cross-section grinding process for cables. Background Art

[0002] When connecting two sections of cables, first, the ends of the cables are cut off. Secondly, the cables are stripped, and the conductor layer, protective layer, and insulating layer of the cables are exposed in a stepped manner. In order to ensure good electrical conductivity after the conductor layers are connected, it is necessary to polish the surface of the cross-section of the conductor layer. After cutting the protective layer and insulating layer of the cable, some burrs generated by the cutting are not completely removed, and it is necessary to polish the protective layer and insulating layer.

[0003] Existing cable grinding equipment generally uses sandpaper or a grinding machine. By a staff member holding the cable and passing the grinding machine through the cable, during the process of the staff member holding the cable, the burrs on the cable surface are likely to scratch the staff member's hand, thus affecting work efficiency. At the same time, when using a grinding machine, a conventional grinding machine cannot grind the junction of the insulating layer and the protective layer of the cable. After the side wall of the cable is ground by the grinding machine, it is necessary to use sandpaper again to grind the junction of the insulating layer and the protective layer, reducing the overall efficiency of cable grinding.

They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0036] In the present invention, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact.

[0037] As Figure 1 shown, a cross-section grinding process for a cable provided by an embodiment of the present invention is mainly completed in cooperation with a cross-section grinding device for a cable. As Figures 2 to 12 shown, a cross-section grinding device for a cable includes a first grinding unit, a second grinding unit, and a mounting shell 110. The first grinding unit and the second grinding unit are both arranged inside the mounting shell 110. A cross-section grinding process for a cable includes the following steps:

[0038] S100: Place the installation shell 110 on the cable to be polished. The installation shell 110 is provided with a first opening 111 to facilitate placing the installation shell 110 on the cable. Specifically, when placing the installation shell 110 on the cable, the angles of the first polishing unit and the second polishing unit also need to be adjusted. The staff adjusts the angles of the first polishing unit and the second polishing unit to ensure that the first polishing unit and the second polishing unit can completely polish the side wall and cross-section of the cable.

[0039] S200: Control the first polishing unit and the second polishing unit to rotate around the cable in the same direction and at the same speed. According to the adjustment of the angles and speeds of the first polishing unit and the second unit, the first polishing unit and the second polishing unit rotate around the side wall of the cable in the same direction and at the same speed, and the first polishing unit and the second polishing unit can jointly polish the side wall of the cable.

[0040] S300: Push the installation shell 110 to reciprocate along the axial direction of the cable. Specifically, after the cable is cut off, the cable is first stripped, and the cross-sections of the conductor layer, protective layer, and insulating layer of the cable are exposed in a stepped manner. Through the staff's reciprocating push of the installation shell 110, the first polishing unit and the second polishing unit reciprocate on the conductor layer, protective layer, and insulating layer on the side wall of the cable. The first polishing unit and the second polishing unit can fully polish the areas that need to be polished on the side walls of the conductor layer, protective layer, and insulating layer of the cable, and at the same time polish the cross-sections of the conductor layer, protective layer, and insulating layer of the cable, avoiding the staff using sandpaper to polish the cable again.

[0041] The installation shell 110 is in the shape of a circular ring sleeve. The installation shell 110 has an inner diameter and an outer diameter. The axis of the installation shell 110 is horizontally arranged. The interior of the installation shell 110 is hollow. A handle 120 is fixedly arranged above the outer side wall of the installation shell 110, facilitating the staff to hold the installation shell 110. A first opening 111 penetrating the inner and outer side walls is arranged at the lower end of the installation shell 110. The setting of the first opening 111 makes the installation shell 110 in a C-shaped structure with an opening. In the initial state, the first opening 111 of the installation shell 110 faces downward, and the handle 120 is at the upper end of the installation shell 110. The first grinding unit has a first installation ring 130. The first installation ring 130 is in a ring shape. The first installation ring 130 is coaxially arranged with the installation shell 110. The first installation ring 130 is rotatably arranged in the installation shell 110. A first notch 131 is arranged on the first installation ring 130. The setting of the first notch 131 makes the first installation ring 130 in a C-shaped structure with an opening. The size of the first notch 131 is the same as that of the first opening 111. In the initial state, the first notch 131 and the first opening 111 are in the same orientation. The second grinding unit has a second installation ring 140. The second installation ring 140 is in a ring shape. The second installation ring 140 is coaxially arranged with the installation shell 110. The first installation ring 130 and the second installation ring 140 are arranged at a left-right interval. The outer diameter size of the second installation ring 140 is the same as that of the first installation ring 130. The second installation ring 140 is rotatably arranged in the installation shell 110. A second notch 141 is arranged on the second installation ring 140. The setting of the second notch 141 makes the second installation ring 140 in a C-shaped structure with an opening. The size of the second notch 141 is the same as that of the first opening 111. In the initial state, the second notch 141 and the first opening 111 are in the same orientation, facilitating the placement of the installation shell 110 on the cable.

[0042] In another embodiment, a first locking rod 150 is fixedly arranged on the first mounting ring 130. The first locking rod 150 is arranged parallel to the axis of the first mounting ring 130. A guiding groove 151 is arranged on the first locking rod 150, and the guiding groove 151 extends along the axial direction of the first locking rod 150. A locking block 152 is arranged on the first locking rod 150, and the locking block 152 can slide along the guiding groove 151. A second locking rod 160 is fixedly arranged on the second mounting ring 140. The second locking rod 160 is arranged parallel to the axis of the second mounting ring 140. A locking groove is arranged on the second locking rod 160, and the locking block 152 can slide along the locking groove. In the initial state, the second locking rod 160 and the first locking rod 150 are on both sides of the first opening 111 of the mounting shell 110. After the first mounting ring 130 rotates counterclockwise by 90 degrees and the second mounting ring 140 rotates clockwise by 90 degrees, the first locking rod 150 and the second locking rod 160 are on the same straight line. The staff pushes the locking block 152 to slide along the guiding groove 151, gradually making part of the locking block 152 enter the locking groove. When part of the locking block 152 enters the locking groove, when the first mounting ring 130 rotates, the second mounting ring 140 rotates synchronously, reducing the input of power and at the same time reducing the waste of resources.

[0043] In another embodiment, a first driving unit is fixedly arranged in the mounting shell 110. The first driving unit can drive the first mounting ring 130 and the second mounting ring 140 to rotate around their own axes. Specifically, the first driving unit includes a driving shaft 210, a first driving wheel 230 and a second driving wheel 240. The driving shaft 210 is horizontally and rotatably arranged inside the mounting shell 110, and the length of the driving shaft 210 is greater than the distance between the first mounting ring 130 and the second mounting ring 140. A driving motor 220 is fixedly arranged on the mounting shell 110. The power output shaft of the driving motor 220 is fixedly connected to the end of the driving shaft 210. The start of the driving motor 220 can drive the driving shaft 210 to rotate around its own axis. The first driving wheel 230 and the second driving wheel 240 are both rotatably arranged on the driving shaft 210. Teeth are arranged on the side walls of the first driving wheel 230 and the second driving wheel 240. The first driving wheel 230 and the second driving wheel 240 are arranged at intervals left and right.

The first driving wheel 230 can mesh with the first mounting ring 130, and the second driving wheel 240 can mesh with the second mounting ring 140. In the initial state, the first driving wheel 230 is in the state of meshing with the first mounting ring 130, and the second driving wheel 240 is in the state of meshing with the second mounting ring 140.

[0044] A limiter is provided on the drive shaft 210, and the limiter can prevent the first drive wheel 230 and the second drive wheel 240 from rotating on the drive shaft 210. Specifically, the limiter includes a first limiting ring 250 and a second limiting ring 260. A first retaining ring 270 and a second retaining ring 280 are fixedly provided on the drive shaft 210, and the first retaining ring 270 and the second retaining ring 280 are arranged at intervals left and right. The first limiting ring 250 is slidably connected to the drive shaft 210, and a first driving cylinder 310 is connected between the first limiting ring 250 and the first retaining ring 270. When the first driving cylinder 310 is started, it can push the first limiting ring 250 to slide along the drive shaft 210. A first limiting block is fixedly provided on the first limiting ring 250. The first limiting ring 250 is arranged on one side of the first drive wheel 230. A first limiting groove with an opening facing the first limiting ring 250 is provided on the first drive wheel 230. Driven by the first driving cylinder 310, the first limiting block can enter the first limiting groove, and the first limiting block can prevent the first drive wheel 230 from rotating on the drive shaft 210, so that the drive shaft 210 can drive the first drive wheel 230 to rotate synchronously. The second limiting ring 260 is slidably connected to the drive shaft 210, and a second driving cylinder 320 is connected between the second limiting ring 260 and the second retaining ring 280. When the second driving cylinder 320 is started, it can push the second limiting ring 260 to slide along the drive shaft 210. A second limiting block is fixedly provided on the second limiting ring 260. The second limiting ring 260 is arranged on one side of the second drive wheel 240. A second limiting groove with an opening facing the second limiting ring 260 is provided on the second drive wheel 240. Driven by the second driving cylinder 320, the second limiting block can enter the second limiting groove, and the second limiting block can prevent the second drive wheel 240 from rotating on the drive shaft 210, so that the drive shaft 210 can drive the second drive wheel 240 to rotate synchronously. The first driving cylinder 310 and the second driving cylinder 320 can be started or closed simultaneously, so that the rotation states of the first drive wheel 230 and the second drive wheel 240 on the drive shaft 210 are kept consistent.

[0045] In another embodiment, the first mounting ring 130 has an inclined first side wall 410. When the first mounting ring 130 is in the initial state, the thickness of the upper end of the first mounting ring 130 is less than the thickness of the lower end of the first mounting ring 130. A first sliding groove 420 extending radially along the first mounting ring 130 is provided on the first side wall 410. In the initial state, the first sliding groove 420 is in a vertical state, and the first sliding groove 420 and the first opening 111 are on the same diameter line of the first mounting ring 130.

The first grinding belt 430 is sequentially wound around the first driving wheel 440 and the two first supporting wheels 450, so that the first grinding belt 430 forms a triangular structure. In the initial state, under the action of the first spring, the first grinding belt 430 is in a tensioned state. The plane where the first grinding belt 430 is located is always parallel to the first side wall 410. Then, the surface of the first grinding belt 430 has an included angle with the cable axis, and one side of the triangular structure formed by the first grinding belt 430 is below the horizontal reference plane passing through the axis of the first mounting ring 130. When the cable enters the first notch 131, the edge of the first grinding belt 430 first contacts the side wall of the cable. The first driving wheel 440 slides an appropriate distance along the first sliding groove 420, and the first spring deforms, so that the first grinding belt 430 is always in a tensioned state.

[0046] Two first auxiliary rollers 460 are rotatably arranged on the first side wall 410. Each first auxiliary roller 460 is arranged on one side of a first supporting wheel 450, and the first auxiliary roller 460 is between the two first supporting wheels 450.

[0047] In another embodiment, the second mounting ring 140 has an inclined second sidewall. When the second mounting ring 140 is in the initial state, the thickness of the upper end of the second mounting ring 140 is less than the thickness of the lower end of the second mounting ring 140, and the second sidewall approaches the first sidewall 410. A second sliding groove 530 extending radially along the second mounting ring 140 is provided on the second sidewall.

A second elastic member is provided between the second fixing portion and the end of the second sliding groove 530. The second elastic member is a second spring. When the second spring is in the original length state, the second fixing portion is at the end of the second sliding groove 530. Two second mounting holes 540 are provided on the second sidewall. The two second mounting holes 540 are on both sides of the second notch 141. Each second supporting wheel 520 is rotatably mounted in a second mounting hole 540, and the second supporting wheel 520 is always perpendicular to the second sidewall. A second motor is provided in each second mounting hole 540, and each second motor drives a second supporting wheel 520 to rotate. The second grinding belt 480 is sequentially wound around the second driving wheel 510 and the two second supporting wheels 520, so that the second grinding belt 480 forms a triangular structure. In the initial state, under the action of the second spring, the second grinding belt 480 is in a tensioned state. The plane where the second grinding belt 480 is located is always parallel to the second sidewall. Then, the surface of the second grinding belt 480 has an included angle with the cable axis, and one side of the triangular structure formed by the second grinding belt 480 is below the horizontal reference plane passing through the axis of the second mounting ring 140. The length of the second grinding belt 480 is the same as the length of the first grinding belt 430, and the horizontal height of the second supporting wheel 520 is the same as that of the first supporting wheel 450. Then, when the cable enters the second notch 141, the edge of the second grinding belt 480 and the edge of the first grinding belt 430 simultaneously contact the sidewall of the cable. The second driving wheel 510 slides along the second sliding groove 530, and the second spring deforms, so that the second grinding belt 480 is always in a tensioned state.

[0048] Two second auxiliary rollers 550 are rotatably arranged on the second side wall. Each second auxiliary roller 550 is arranged on one side of a second support wheel 520, and the second auxiliary roller 550 is located between two second support wheels 520. The second auxiliary roller 550 is used to prevent the second grinding belt 480 from detaching from the second support wheel 520.

[0049] In another embodiment, push rods 470 are arranged on the side walls of the first mounting ring 130 and the second mounting ring 140 that are away from each other. Workers can drive the push rods 470 to drive and change the angles of the first mounting ring 130 or the second mounting ring 140 on the cable, facilitating the workers to drive the rotation of the first mounting ring 130 and the second mounting ring 140 during the preliminary preparation work.

[0050] Combined with the above embodiments, the working process of a cross-section grinding process for a cable provided by an embodiment of the present invention is as follows:

[0051] During work, the worker holds the handle 120 of the mounting shell 110 and places the mounting shell 110 on the cable to be ground. Since in the initial state, the first opening 111, the first notch 131, and the second notch 141 all face downward, it is convenient for the cable to enter the circular ring sleeve of the mounting shell 110. When the cable enters the circular ring sleeve of the mounting shell 110, the cable jointly presses the first grinding belt 430 and the second grinding belt 480. The first driving wheel 440 slides along the first chute 420, and the second driving wheel 510 slides along the second chute 530. Under the action of the first spring, the first grinding belt 430 is in a tensioned state. Under the action of the second spring, the second grinding belt 480 is in a tensioned state. At the same time, control the first driving cylinder 310 and the second driving cylinder 320 to start. The first driving cylinder 310 and the second driving cylinder 320 shorten simultaneously. The first driving cylinder 310 pulls the first limiting ring 250 to gradually move away from the first driving wheel 230, and the first limiting block on the first limiting ring 250 gradually disengages from the first limiting groove, ensuring that the first driving wheel 230 can freely rotate on the driving shaft 210. The second driving cylinder 320 pulls the second limiting ring 260 to gradually move away from the second driving wheel 240, and the second limiting block on the second limiting ring 260 gradually disengages from the second limiting groove, ensuring that the second driving wheel 240 can freely rotate on the driving shaft 210.

[0052] The worker controls the first mounting ring 130 to rotate counterclockwise by 90 degrees and the second mounting ring 140 to rotate clockwise by 90 degrees by pushing the two push rods 470, ensuring that the first locking rod 150 and the second locking rod 160 are in the same straight line. The worker pushes the locking block 152 to slide along the guiding groove 151, gradually making part of the locking block 152 enter the locking groove. When part of the locking block 152 enters the locking groove, the second mounting ring 140 rotates synchronously when the first mounting ring 130 is rotated.

[0053] Subsequently, the first driving cylinder 310 and the second driving cylinder 320 are controlled to start again. The first driving cylinder 310 and the second driving cylinder 320 extend simultaneously. The first driving cylinder 310 pushes the first limiting ring 250 to gradually approach the first driving wheel 230, and the first limiting block on the first limiting ring 250 gradually enters the first limiting groove, ensuring that the first driving wheel 230 cannot rotate freely on the driving shaft 210. The second driving cylinder 320 pushes the second limiting ring 260 to gradually approach the second driving wheel 240, and the second limiting block on the second limiting ring 260 gradually enters the second limiting groove, ensuring that the second driving wheel 240 cannot rotate freely on the driving shaft 210.

[0054] Start the driving motor 220, two first motors and two second motors. The driving motor 220 drives the driving shaft 210 to rotate, and the driving shaft 210 drives the first limiting ring 250 and the second limiting ring 260 to rotate synchronously. Since the first limiting block on the first limiting ring 250 enters the first limiting groove and the second limiting block on the second limiting ring 260 enters the second limiting groove, the first driving wheel 230 and the second driving wheel 240 rotate synchronously. Since the first driving wheel 230 always meshes with the side wall of the first mounting ring 130 and the second driving wheel 240 always meshes with the side wall of the second mounting ring 140, when the driving shaft 210 rotates, the first mounting ring 130 and the second mounting ring 140 rotate at the same speed and in the same direction. When the two first motors start, the two first supporting wheels 450 rotate synchronously, and then the first grinding belt 430 wound around the first driving wheel 440 and the two first supporting wheels 450 rotates. When the two second motors start, the two second supporting wheels 520 rotate synchronously, and then the second grinding belt 480 wound around the second driving wheel 510 and the two second supporting wheels 520 rotates. The rotating first grinding belt 430 and the rotating second grinding belt 480 jointly polish the side wall of the cable.

[0055] Due to the inclined setting of the first side wall 410 of the first mounting ring 130, while the first driving wheel 440 is always perpendicular to the first side wall 410, and both of the two first supporting wheels 450 are always perpendicular to the first side wall 410, the plane where the first grinding belt 430 is located always remains parallel to the first side wall 410. Then, there is an angle between the surface of the first grinding belt 430 and the cable axis. When the first grinding belt 430 contacts the cable side wall, one side of the first grinding belt 430 first contacts the cable. With the extrusion of the cable on the first grinding belt 430, when the first mounting ring 130 is in the initial position, the position of the cable passing through the horizontal reference plane of the axis is in full contact with the entire surface of the first grinding belt 430. At the same time, according to the inclined setting of the second side wall of the second mounting ring 140, and the second driving wheel 510 is always perpendicular to the second side wall, and both of the two second supporting wheels 520 are always perpendicular to the second side wall, the plane where the second grinding belt 480 is located always remains parallel to the second side wall. Furthermore, there is an angle between the surface of the second grinding belt 480 and the cable axis. When the second grinding belt 480 contacts the cable side wall, one side of the second grinding belt 480 first contacts the cable. With the extrusion of the cable on the second grinding belt 480, when the second mounting ring 140 is in the initial position, the position of the cable passing through the horizontal reference plane of the axis is in full contact with the entire surface of the second grinding belt 480.

[0056] With the start of the driving motor 220, the first mounting ring 130 and the second mounting ring 140 rotate synchronously, and the first grinding belt 430 and the second grinding belt 480 jointly grind the cable. At the same time, the staff reciprocates along the axis of the cable by pushing the handle 120. Since the conductor layer, the protective layer, and the insulating layer are in a stepped shape after the end of the cable is stripped, first, the insulating layer of the cable with a larger diameter is ground. After the grinding of the insulating layer of the cable is completed, the staff pushes the handle 120 to move the first grinding belt 430 to the junction of the insulating layer and the protective layer. Due to the certain angle between the first grinding belt 430 and the cable, the steps at the junction of the insulating layer and the protective layer are ground through the angle between the first grinding belt 430 and the cable. After the grinding of the steps at the junction of the insulating layer and the protective layer is completed, the staff pushes the handle 120 to move the first grinding belt 430 and the second grinding belt 480 to the protective layer of the cable, and the protective layer of the cable is ground by the first grinding belt 430 and the second grinding belt 480. Thus, the insulating layer, the protective layer, and the conductor layer of the cable are ground in sequence, thereby improving the grinding efficiency.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
