Description

Technical Field

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

[0002] When connecting two sections of cable, the ends of the cable are first cut off, and then the cable is stripped to expose the conductor layer, protective layer and insulating layer of the cable in a stepped manner. In order to ensure that the conductor layer has good conductivity after connection, the surface of the cross section of the conductor layer needs to be polished. After cutting the protective layer and insulating layer of the cable, some burrs generated by the cutting are not completely removed, and the protective layer and insulating layer need to be polished.

[0003] Existing cable grinding equipment generally uses sandpaper or a grinder. The worker holds the cable and passes the grinder through the cable. During the worker's holding of the cable, the burrs on the cable surface can easily scratch the worker's hands, thereby affecting work efficiency. At the same time, when using the grinder, conventional grinders cannot grind the junction between the insulation layer and the protective layer of the cable. After the grinder has polished the side wall of the cable, sandpaper must be used again to grind the junction between the insulation layer and the protective layer, which reduces the overall efficiency of cable grinding.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The serial numbers assigned to the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In the present invention, unless otherwise clearly specified and limited, a first feature being “on” or “under” a second feature may mean that the first and second features are in direct contact with each other.

[0022] like Figure 1 As shown, an embodiment of the present invention provides a cable cross-section grinding process, and a cable cross-section grinding process is mainly completed by a cable cross-section grinding device, such as Figures 2 to 12 As shown, a cross-section grinding device for a cable includes a first grinding unit, a second grinding unit and an installation shell 110, wherein the first grinding unit and the second grinding unit are both arranged inside the installation shell 110, and a cross-section grinding process for a cable includes the following steps: S100: Place the installation shell 110 on the cable to be polished. The installation shell 110 is provided with a first opening 111, which is convenient for 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 must 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.

[0023] S200: Control the first grinding unit and the second grinding unit to rotate around the cable in the same direction and at the same speed. According to the adjustment of the angle and speed of the first grinding unit and the second unit, the first grinding unit and the second grinding unit rotate around the side wall of the cable in the same direction and at the same speed, and the first grinding unit and the second grinding unit can grind the side wall of the cable together.

[0024] S300: Push the installation shell 110 to move back and forth along the axial direction of the cable. Specifically, after the cable is cut, the cable is first stripped to expose the cross-sections of the conductor layer, protective layer and insulating layer of the cable in a stepped shape. Through the reciprocating push of the installation shell 110 by the staff, the first polishing unit and the second polishing unit reciprocate on the conductor layer, protective layer and insulating layer of the side wall of the cable. The first polishing unit and the second polishing unit can fully polish the places where the conductor layer, protective layer and insulating layer of the side wall of the cable need to be polished, and polish the cross-sections of the conductor layer, protective layer and insulating layer of the cable at the same time, avoiding the staff from using sandpaper to polish the cable again.

[0025] The installation shell 110 is in the shape of a circular ring, and has an inner diameter and an outer diameter. The axis of the installation shell 110 is arranged horizontally, and the interior of the installation shell 110 is hollow. A handle 120 is fixedly arranged above the outer wall of the installation shell 110, so that the staff can support the installation shell 110. The lower end of the installation shell 110 is provided with a first opening 111 penetrating the inner and outer walls. The arrangement of the first opening 111 makes the installation shell 110 present 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 located at the upper end of the installation shell 110.

A locking block 152 is arranged on the first locking rod 150, and the locking block 152 can be slidably disposed along the guide groove 151. A second locking rod 160 is fixedly disposed on the second mounting ring 140, the second locking rod 160 is arranged parallel to the axis of the second mounting ring 140, and a locking groove is arranged on the second locking rod 160, and the locking block 152 can be slidably disposed 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 90 degrees counterclockwise and the second mounting ring 140 rotates 90 degrees clockwise, the first locking rod 150 and the second locking rod 160 are in the same straight line. The staff pushes the locking block 152 to slide along the guide groove 151, gradually allowing part of the locking block 152 to 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, thereby reducing power input and reducing waste of resources.

[0027] In another embodiment, a first driving unit is fixedly disposed in the mounting shell 110, and the first driving unit can drive the first mounting ring 130 and the second mounting ring 140 to rotate around their own axis.

[0033] In another embodiment, a pushing rod 470 is provided on the side walls of the first mounting ring 130 and the second mounting ring 140 that are away from each other. The staff can drive the pushing rod 470 to change the angle of the first mounting ring 130 or the second mounting ring 140 on the cable, so that the staff can drive the rotation of the first mounting ring 130 and the second mounting ring 140 during the preliminary preparation work.

[0034] In combination with the above embodiments, the working process of a cross-section grinding process of a cable provided by the embodiment of the present invention is as follows: During operation, the staff holds the handle 120 of the mounting shell 110 and places the mounting shell 110 on the cable to be polished. In the initial state, the first opening 111, the first notch 131 and the second notch 141 are all facing downward, which facilitates the cable to enter the annular sleeve of the mounting shell 110. When the cable enters the annular sleeve of the mounting shell 110, the cable squeezes the first grinding belt 430 and the second grinding belt 480 together, the first driving wheel 440 slides along the first slide groove 420, and the second driving wheel 510 slides along the second slide groove 530. Under the action of the first spring, the first grinding belt 430 is in a tensioned state, and under the action of the second spring, the second grinding belt 480 is in a tensioned state. At the same time, the first driving cylinder 310 and the second driving cylinder 320 are controlled to start, and the first driving cylinder 310 and the second driving cylinder 320 are shortened at the same time, and 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 rotate freely 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 rotate freely on the driving shaft 210.

[0035] The staff controls the first mounting ring 130 to rotate 90 degrees counterclockwise and the second mounting ring 140 to rotate 90 degrees clockwise by pushing the two pushing rods 470 to ensure that the first locking rod 150 and the second locking rod 160 are in the same straight line. The staff pushes the locking block 152 to slide along the guide groove 151, gradually allowing part of the locking block 152 to 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.

[0036] Then, the first driving cylinder 310 and the second driving cylinder 320 are controlled to start again, and the first driving cylinder 310 and the second driving cylinder 320 are extended at the same time, and 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.

[0037] Start the drive motor 220, the two first motors and the two second motors, the drive motor 220 drives the drive shaft 210 to rotate, and the drive shaft 210 drives the first limit ring 250 and the second limit ring 260 to rotate synchronously. Since the first limit block on the first limit ring 250 enters the first limit groove, and the second limit block on the second limit ring 260 enters the second limit groove, the first drive wheel 230 and the second drive wheel 240 rotate synchronously. Since the first drive wheel 230 is always engaged with the side wall of the first mounting ring 130, and the second drive wheel 240 is always engaged with the side wall of the second mounting ring 140, when the drive shaft 210 rotates, the first mounting ring 130 and the second mounting ring 140 keep rotating at the same speed and in the same direction. When the two first motors are started, the two first support wheels 450 rotate synchronously, and the first grinding belt 430 connected to the first driving wheel 440 and the two first support wheels 450 rotates. When the two second motors are started, the two second support wheels 520 rotate synchronously, and the second grinding belt 480 connected to the second driving wheel 510 and the two second support wheels 520 rotates. The rotating first grinding belt 430 and the rotating second grinding belt 480 grind the cable side wall together.

[0038] Due to the inclined setting of the first side wall 410 of the first mounting ring 130, the first driving wheel 440 is always perpendicular to the first side wall 410, and 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 is always parallel to the first side wall 410, and the surface of the first grinding belt 430 has an angle with 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. As the cable squeezes the first grinding belt 430, when the first mounting ring 130 is in the initial position, the position of the cable through the axis horizontal reference plane contacts 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, the second driving wheel 510 is always perpendicular to the second side wall, and the two second supporting wheels 520 are always perpendicular to the second side wall, the plane where the second grinding belt 480 is located is always parallel to the second side wall, and thus the surface of the second grinding belt 480 has an angle with the cable axis. When the second grinding belt 480 contacts the side wall of the cable, one side of the second grinding belt 480 contacts the cable first. As the cable squeezes the second grinding belt 480 , when the second mounting ring 140 is in the initial position, the position of the cable through the axis horizontal reference plane contacts the entire surface of the second grinding belt 480 .

[0039] As the drive motor 220 is started, 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 grind the cable together. At the same time, the staff pushes the handle 120 to reciprocate along the axis of the cable. Since the conductor layer, protective layer and insulating layer of the cable are stepped after the end is stripped, the insulating layer of the cable with a large diameter is first grinded. After the insulating layer of the cable is polished, the handle 120 is pushed to move the first grinding belt 430 to the junction of the insulating layer and the protective layer. Since the first grinding belt 430 and the cable have a certain angle, the step at the junction of the insulating layer and the protective layer is polished through the angle between the first grinding belt 430 and the cable. After the step at the junction of the insulating layer and the protective layer is polished, 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 polished through the first grinding belt 430 and the second grinding belt 480. Thus, the cable insulation layer, the protective layer and the conductor layer are polished in sequence, thereby improving the polishing efficiency.
