With heating module 2 phase-match ground, still be equipped with the louvre on the body 100, prevent that the high temperature in the line ball cap installation device from causing equipment damage or personnel to scald. The clamping mechanism 3 is configured to bring the heating module 2 into or out of clamping with the crimping cap 200.
According to the invention, the wire pressing cap 200 is stored by using the guide hole 1, and during installation, the wire 300 to be connected is inserted into the guide hole 1 through the installation opening 11 and then inserted into the clamping opening 201 of the wire pressing cap 200, so that the wire 300 to be connected is abutted to the wire pressing cap 200 in the guide hole 1. The heating module 2 heats the wire pressing cap 200, utilizes the characteristic that plastic materials are heated to be softened, enables the wire pressing cap 200 to deform, and then enables the wire pressing cap 200 to be fixedly connected with the wire 300 to be connected inside the wire pressing cap under the action of the clamping mechanism 3. Compared with the operation mode that workers use the wire pressing pliers to press the wire pressing cap 200 with force in the prior art, the wire pressing cap assembly effectively solves the problems of high labor intensity, high error rate, low efficiency and the like when the wire pressing cap 200 is installed. Meanwhile, the problem that the shell of the wire pressing cap 200 is easy to break when being compressed in a low-temperature environment is solved.
With continued reference to fig. 1, in this embodiment, a first installation hole is disposed between the installation opening 11 of the guide hole 1 and the working position 12, the first installation hole is communicated with the guide hole 1 and extends along the radial direction of the guide hole 1, the filling buckle 13 is partially disposed in the first installation hole, the filling buckle 13 can selectively enable the wire pressing cap 200 to enter or leave the working position 12 from the installation opening 11, and the hole wall of the first installation hole serves as a guide channel of the filling buckle 13, so that the filling buckle 13 can move in a direction perpendicular to the guide hole 1, thereby implementing filling of the wire pressing cap 200; meanwhile, the hole wall space of the guide hole 1 can be fully utilized, and the size of the wire pressing cap installation device is reduced. As a preferable technical solution, two loading buckles 13 are provided in the present embodiment, and the two loading buckles 13 are oppositely disposed along the radial direction of the guiding hole 1, so that the control of the crimping cap 200 is more reliable.
As shown in fig. 2, the charging jaw 13 includes a charging chuck 131, a first resilient member 132, and a first control rod 133. One end of the first elastic member 132 is connected to the charging chuck 131, and the other end of the first elastic member 132 is connected to the first control rod 133. The first resilient member 132 may be compressed when the crimp cap 200 is moved into the work station 12 to facilitate movement of the crimp cap 200 into the work station 12. The first resilient component 132 may be compressed in a wide variety of ways, including a spring, bellows, or other thermoplastic resilient member, and in the present embodiment, is illustratively a spring.
The loading chuck 131 is protruded on the inner wall of the guide hole 1, and in this embodiment, the loading chuck 131 is designed to have a triangular prism structure and a right triangle cross section. In practice, the plane of the hypotenuse of the right triangle in cross section is used as the guide surface 1311, and the guide surface 1311 faces the mounting opening 11. When filling line ball cap 200 in to line ball cap installation device, line ball cap 200 earlier with spigot 1311 butt, spigot pressure transmission to first elastic component 132 is received first elastic component 132, and first elastic component 132 receives the axial shrink that pressure drove and load dop 131 along first elastic component 132, makes and loads dop 131 shrink to first mounting hole in, realizes line ball cap 200 and gets into work position 12 by installing port 11.
Meanwhile, a plane on which one leg of the right triangle of the cross section of the loading chuck 131 is located is defined as an abutment surface 1312. After the wire pressing cap 200 enters the working position 12 through the mounting opening 11, the first elastic component 132 no longer bears axial pressure, and the filling chuck 131 rebounds to the initial position under the elastic action of the first elastic component 132, that is, the filling chuck 131 is convexly arranged on the inner wall of the guide hole 1. At this time, the wire crimping cap 200 at the operating position 12 can abut against the abutment surface 1312, and the abutment force is horizontal, and the vertical axial pressure cannot be applied to the loading chuck 131, so that the first elastic member 132 is prevented from contracting, and the wire crimping cap 200 is restricted from leaving the operating position 12.
When the wire pressing cap 200 is fixedly connected with the wire 300 to be connected, which is fixedly connected with the wire pressing cap 200, needs to be taken out from the guide hole 1. With continued reference to fig. 2, in order to achieve the above function, the loading chuck 131 has a second motion mode, that is, the first control rod 133 can drive the loading chuck 131 and the first elastic component 132 to move together along the radial direction of the guiding hole 1, so that the first elastic component 132 and the loading chuck 131 move together into the first mounting hole, the abutting surface 1312 is disengaged from the wire pressing cap 200, and the function of taking out the to-be-connected wire 300 fixedly connected with the wire pressing cap 200 from the guiding hole 1 is achieved.
Further, for the convenience of operation, we connect the first control lever 133 with the first control switch 10 on the outer surface of the body 100 through the first transmission assembly 5. When the first control switch 10 is triggered, the first control rod 133 can drive the loading chuck 131 and the first elastic component 132 to move together into the first mounting hole along the radial direction of the guide hole 1, so as to take out the to-be-connected wire 300 fixedly connected with the wire pressing cap 200 from the guide hole 1; when the first control switch 10 is reset or the first control switch 10 is triggered again, the first control rod 133 can drive the loading chuck 131 and the first elastic component 132 to reset, so as to load the wire pressing cap 200 or limit the wire pressing cap 200 to leave the working position 12. It should be specifically noted that the first transmission assembly 5 in the present application has many kinds, and is not limited herein, and may be a pure mechanical structure, an electrically-controlled driving mechanical structure, or an electromagnetic control structure.
In the present embodiment, the first transmission assembly 5 is taken as an example of a solenoid valve, which exemplifies the indicated embodiment. The first control rod 133 is provided at its end with a first solenoid valve (not shown), and the first solenoid valve and the first control switch 10 are both connected to a circuit board (not shown) in communication. The first electromagnetic valve comprises a first valve body fixedly connected with the guide hole 1 and a first valve core in sliding connection with the first valve body, and one end, far away from the filling chuck 131, of the first control rod 133 is connected with the movable end of the first valve core. When the first control switch 10 is triggered, the first electromagnetic valve is conducted, the first valve core and the first control rod 133 connected with the first valve core are attracted by magnetic force, so that the first control rod 133 drives the filling chuck 131 and the first elastic component 132 to move into the first mounting hole along the radial direction of the guide hole 1; when the first control switch 10 is reset or the first control switch 10 is triggered again, the first solenoid valve is turned off, and the first control rod 133 drives the charging chuck 131 and the first elastic component 132 to reset.
Further, in order to make a plurality of line ball caps 200 of line ball cap installation device can install in succession, the one end of keeping away from work position 12 in the guiding hole 1 is equipped with storage bit 16, and storage bit 16 can hold a plurality of line ball caps 200 in guiding hole 1, to the fortune dimension workman of high altitude construction and special environment operation, load the operation many times during the work very difficultly, so set up and can avoid because of load the danger and the inconvenience that bring many times.
With continued reference to fig. 1, a second mounting hole is provided between the storage position 16 and the working position 12 of the guide hole 1, and the second mounting hole is communicated with the guide hole 1 and extends along the radial direction of the guide hole 1. The part of the closure buckle 14 is arranged in the second mounting hole, the closure buckle 14 can retract along the guide hole 1 so as to selectively enable the wire pressing cap 200 to enter or leave the storage position 16, the hole wall of the second mounting hole is used as a guide channel of the closure buckle 14, the hole wall space of the guide hole 1 is fully utilized, and the volume of the wire pressing cap mounting device is compressed. As a preferred technical solution, two limit buckles 14 are provided in this embodiment, and the two limit buckles 14 are oppositely disposed along the radial direction of the guide hole 1.
During loading, the shut-off buckle 14 retracts, so that the plurality of crimping caps 200 can smoothly enter the storage position 16. After the filling is finished, the closure buckle 14 resets, and the line pressing cap 200 is limited to freely enter the working position 12 through the closure buckle 14; when the installation of the last crimp cap 200 located at the work station 12 is completed, the shut-off catch 14 is retracted, so that the crimp cap 200 located closest to the shut-off catch 14 in the storage position 16 enters the work station 12. The storage bit 16 and the working position 12 are distinguished through the closure buckle 14, the screening function is realized, the heating module 2 of the line pressing cap installation device can accurately heat and install one line pressing cap 200 on the working position 12 when working at every time, and the installation quality of the line pressing cap 200 is guaranteed.
As shown in fig. 3, the closure buckle 14 includes a limit chuck 141 and a second control rod 142, the second control rod 142 is connected to the limit chuck 141, and the second control rod 142 can drive the limit chuck 141 and can be selectively protruded from the guide hole 1.
Specifically, in the use process, the second control rod 142 can drive the limiting chuck 141 to retract, so that the wire pressing cap 200 enters the working position 12 from the storage position 16 or enters the storage position 16 from the working position 12, and the limiting chuck 141 plays a role in limiting and screening; when the limiting chuck 141 retracts, the limiting chuck can be used for loading the wire pressing cap 200 and the wire pressing cap 200 closest to the working position 12 in the storage position 16 enters the working position 12; when the second control rod 142 drives the limit chuck 141 to protrude from the guide hole 1, the limit chuck is used for limiting, so that the wire pressing cap 200 in the storage bit 16 cannot enter the working position 12.
In the present embodiment, the limit chuck 141 mainly performs limiting and screening functions, and the shape of the limit chuck 141 may not be limited in theory. However, in order to achieve a better screening effect, the stopper chuck 141 is also preferably formed in a triangular prism structure. In the course of the work, line ball cap 200 gets into the work position 12 by storage bit 16, and when spacing dop 141 resets, because spacing dop 141 is the triangular prism structure, and the one end that second control lever 142 was kept away from to spacing dop 141 is most advanced, and spacing dop 141 of being convenient for inserts between the line ball cap 200 that piles up to separate line ball cap 200 and play the screening effect. The end of the limiting chuck 141 away from the second control rod 142 is a pointed end, which can reduce the requirement for the insertion gap compared with a flat end. For example, if the wire crimping cap 200 is not a V-shaped structure as shown in the drawings, but a C-shaped structure, the stacked gap is reduced, and is difficult to be separated by the position-limiting chucks 141, and the position-limiting chucks 141 can be well separated by the triangular prism structure, so that the application range of the wire crimping cap mounting device is increased. Further, the cross section of this triangular prism is right triangle, and the inclined plane sets up towards storage bit 16, at the in-process of screening, spacing dop 141's inclined plane and the line ball cap 200 butt that is spaced apart, when the line ball cap 200 that is close to work position 12 needs to get into work position 12, this inclined plane can play the guide effect, can not die line ball cap 200 card, the cross-section is right triangle then is favorable to reducing the most advanced contained angle that second control lever 142 was kept away from to spacing dop 141, be favorable to inserting between the line ball cap 200 of piling up more.
Further, for the convenience of operation, the second control rod 142 is connected to the second control switch 20 on the outer surface of the body 100 through the second transmission assembly 6. When the second control switch 20 is triggered, the second control rod 142 can drive the limit chuck 141 to move axially along the second mounting hole, and the wire pressing cap 200 enters the working position 12 from the storage position 16 or enters the storage position 16 from the working position 12; when the second control switch 20 is reset or the second control switch 20 is triggered again, the second control rod 142 can drive the limiting chuck 141 to reset, so that the influence of the wire pressing cap 200 in the storage bit 16 on the working position 12 can be avoided, and meanwhile, the wire pressing cap 200 cannot be used for filling. It should be specifically noted that the second transmission assembly 6 in the present application has many kinds, and is not limited herein, and may be a pure mechanical structure, an electrically-controlled driving mechanical structure, or an electromagnetic control structure.
In the embodiment, the second transmission assembly 6 is taken as an electromagnetic valve as an example to exemplarily indicate the implementation mode. A second solenoid valve (not shown) and a circuit board (not shown) are disposed between the end of the second control rod 142 away from the limit chuck 141 and the second control switch 20, and the circuit board is the same as the circuit board connected to the first control rod 133, so that the internal structure is simplified.
The second solenoid valve and the second control switch 20 are both connected to a circuit board (not shown) in communication. The second electromagnetic valve comprises a second valve body fixedly connected with the guide hole 1 and a second valve core in sliding connection with the second valve body, and one end, far away from the limit chuck 141, of the second control rod 142 is connected with the movable end of the second valve core. When the second control switch 20 is triggered, the second electromagnetic valve is conducted, the second valve core and the second control rod 142 connected with the second valve core are attracted by magnetic force, and the second control rod 142 drives the limiting chuck 141 to move into the second mounting hole; when the second control switch 20 is reset or the second control switch 20 is triggered again, the second electromagnetic valve is turned off, and the second control rod 142 drives the limit chuck 141 to reset.
Further, as shown in fig. 1, one end of the storage bit 16, which is far away from the mounting port 11, is provided with a second elastic assembly 15, one end of the second elastic assembly 15 abuts against the guide hole 1, and the other end abuts against the wire pressing cap 200, so as to drive the wire pressing cap 200 to enter the working position 12 from the storage bit 16. In the embodiment, the second elastic element 15 is a spring, one end of the second elastic element 15 abutting against the guide hole 1 is a fixed end, and the other end is a movable end. When the crimp cap 200 is not present in the guide hole 1, the movable end of the second elastic assembly 15 abuts against the shut-off catch 14. When the wire pressing cap 200 is filled, the wire pressing cap 200 is abutted against the movable end, the second elastic assembly 15 is compressed, the movable end moves close to the fixed end, and the wire pressing cap 200 smoothly enters the storage position 16. After the loading is finished, the pressing line cap 200 is abutted with the cut-off buckle 14 under the elastic force of the second elastic assembly 15.
It should be noted that whether the inclined surface of the limit chuck 141 can successfully perform the limiting function depends on the relationship between the component force of the pressure applied to the inclined surface by the line pressing cap 200 in the vertical direction and the supporting force of the second control rod 142 on the limit chuck 141. When the wire pressing cap 200 is abutted against the closure buckle 14 by the elastic force of the second elastic component 15, the component force of the pressure applied to the limiting chuck 141 by the wire pressing cap 200 in the direction perpendicular to the guide hole 1 is always smaller than the supporting force of the second control rod 142 to the limiting chuck 141, and the limiting effect can be realized.
With continued reference to fig. 1, the heating module 2 includes a heating resistor 21, a power supply 22 and a heating circuit (not shown in the figure), the heating circuit is connected to the circuit board in communication, the power supply 22 heats the heating resistor 21 through the heating circuit, the heating resistor 21 is disposed in the working position 12 and connected to the clamping mechanism 3, and the clamping mechanism 3 drives the heating resistor 21 to clamp or separate from the pressing cap 200 of the working position 12. During the use, after turning on heating circuit's control switch, then control clamping mechanism 3 makes heating resistor 21 and the contact of line ball cap 200 and presss from both sides tightly, realizes line ball cap 200 and treats being connected of wiring 300. The clamping is also carried out while heating, so that the installation quality can be better ensured. Compared with other heating modes, the heating process adopting circuit resistance heating is easier to control, the safety and the stability are ensured, meanwhile, the occupied volume of the electric control system is smaller, the volume of the wire pressing cap mounting device can be reduced, and the wire pressing cap mounting device can be carried about.
Preferably, this embodiment is provided with 2 heating resistors 21, and sets up along the radial opposition of guiding hole 1, so set up and can heat line ball cap 200 simultaneously in two symmetrical directions, make line ball cap 200 and the connection of treating wiring 300 more firm, also accelerated the installation rate. Further preferably, the 2 heating resistors 21 are all adjustable resistors. The power source 22 is usually a dc battery, and the heating power of the heating module 2 can be changed by adjusting the resistance value of the heating resistor 21, so that the wire pressing cap mounting device is adapted to wire pressing caps 200 with different materials or thicknesses. In addition, the heating circuit is also provided with an overload protector, and when the current is overloaded, the overload protector can automatically cut off the power supply, so that the accidents of electric leakage or scalding are prevented.
As shown in fig. 4, the clamping mechanism 3 in the present embodiment is realized as follows: the clamping mechanism 3 is a seven-bar linkage mechanism and comprises three fixed rotating shafts. In the figure, all the transmission rods are hinged, the third control switch 30 is fixedly connected with the middle part of the first transmission rod 31, and the third control switch 30 and the first transmission rod 31 can rotate around the first rotating shaft 301. One end of the first transmission rod 31 is connected with a second transmission rod 32, a third transmission rod 33 and a fourth transmission rod 34 in sequence, wherein the middle part of the third transmission rod 33 is rotatably connected with a third rotating shaft 303, and one end of the fourth transmission rod 34 far away from the third transmission rod 33 is connected with the heating resistor 21. The other end of the first transmission rod 31 is connected with a fifth transmission rod 35, a sixth transmission rod 36 and a seventh transmission rod 37 in sequence, wherein the middle part of the sixth transmission rod 36 is rotatably connected with the second rotating shaft 302, and one end of the seventh transmission rod 37 far away from the sixth transmission rod 36 is connected with the heating resistor 21.
When the third control switch 30 is pulled counterclockwise, the third control switch 30 drives the first driving rod 31 to rotate counterclockwise around the first rotating shaft 301, and then both ends of the first driving rod 31 move in opposite directions. The second transmission rod 32 is driven by the first transmission rod 31 to further drive the third transmission rod 33 to rotate clockwise around the third rotating shaft 303, so that the fourth transmission rod 34 pushes the heating module 2 to move close to the wire pressing cap 200; at the same time, the first transmission rod 31 drives the sixth transmission rod 36 via the fifth transmission rod 35 to rotate counterclockwise about the second rotating shaft 302, so that the seventh transmission rod 37 pushes the heating module 2 from the other side to move closer to the wire crimping cap 200. When the third control switch 30 is released, the third control switch 30 drives the first transmission rod 31 to rotate clockwise around the first rotating shaft 301 together under the action of the rear end return spring for returning, and the other transmission rods return under the action of the first transmission rod 31, so that the two heating modules 2 are both far away from the wire pressing cap 200. It should be noted that the clamping mechanism 3 is only one implementation manner, and in other embodiments, a person skilled in the art may set the clamping mechanism according to practical situations as long as the clamping or the separating of the heating resistor 21 with respect to the wire pressing cap 200 can be achieved.
With continued reference to fig. 1, as an alternative solution, the main body 100 is provided with a visible window 4 facing the working position 12. An operator can observe the condition that the wire pressing cap enters the working position 12 from the storage position 16 and the heating process of the wire pressing cap 200 by the heating module 2 through the visual window 4, and the installation quality of the wire pressing cap 200 can be further improved by visualizing the working process. In this embodiment, the visible window 4 is made of high temperature glass, which has the characteristics of high transparency, high temperature resistance, good thermal stability, stable chemical properties, and the like, and can still maintain the original permeability and transparency of the glass in a high temperature environment.
As an optional technical solution, the body 100 further includes a handle 101, and the handle 101 provides an integrated space for the first control switch 10, the second control switch 20, the power source 22 of the heating module 2 and the heating circuit, so that the wire pressing cap installation device can be made into not only a larger fixing device, but also a relatively smaller portable mobile device. The small portable wire pressing cap installation device can realize the handheld operation of a single hand, and the practicability of the wire pressing cap installation device is enhanced.

Example two
As shown in fig. 5, the present embodiment is different from the first embodiment in that the second transmission assembly 6 for connecting the second control rod 142 and the second control switch 20 is a mechanical structure. The second transmission assembly 6 comprises a cam 61 fixedly connected with the second control switch 20, the second control switch 20 and the cam 61 can rotate around a cam shaft 601 together, the second transmission assembly 6 further comprises a link spring 62 and a buckle link 63, wherein the middle of the buckle link 63 is connected with a fixed shaft 602, and the buckle link 63 can rotate around the fixed shaft 602. In the initial position, the catch link 63 compresses the link spring 62, one end of the catch link 63 abuts against the cam 61 by the urging force of the link spring 62, and the other end of the catch link 63 is hinged to the second lever 142.
When an external force acts on the second control switch 20, the second control switch 20 rotates clockwise about the cam shaft 601 together with the cam 61. At this time, the latch link 63 rotates around the fixed shaft 602 under the urging force of the link spring 62, one end of the latch link 63 slides along the cam guide surface 611 of the cam 61, and stops sliding to the termination point 612, the limiting surface 613 and the cam guide surface 611 form a "V" shaped structure, and the lowest point of the "V" shaped structure is the termination point 612. The limiting surface 613 is used to limit the over travel of the catch link 63. While one end of the snap link 63 slides along the cam guide surface 611 of the cam 61, the other end of the snap link 63 pulls the second control rod 142, so that the second control rod 142 drives the limit chuck 141 to move into the hole wall of the guide hole 1 along the radial direction of the guide hole 1. At this point, the crimp cap 200 may be moved into the storage location 16 or out of the storage location 16 by the retaining clip 14.
After the wire pressing cap 200 enters the storage position 16 or leaves the storage position 16, the external force acting on the second control switch 20 is removed, and the second control switch 20 and the cam 61 are reset to the initial position counterclockwise around the cam shaft 601 under the action of the reset spring. At this time, the latch link 63 compresses the link spring 62 to rotate around the fixed shaft 602 by the pushing force of the cam 61 to the initial position, and the second control rod 142 drives the limit chuck 141 to protrude from the guide hole 1. Preferably, a return spring is also arranged between the limit chuck 141 and the guide hole 1, and the return spring of the second control switch 20 act simultaneously, so that the return elastic force is increased, and the return speed is accelerated. It should be noted that the moment formed by the elastic force of the return spring acting on the second control switch 20 and the cam shaft 601 is always larger than the moment formed by the elastic force of the link spring 62 acting on the catch link 63 and the cam shaft 601. So that a normal resetting of the second transmission assembly 6 can be achieved.
It should be noted that the time interval from the external force acting on the second control switch 20 to the cancellation of the external force is very short, and only one pressing cap 200 is moved from the storage area 16 to the working position 12 in the time interval. This is a motion control problem and needs to be specifically calculated in conjunction with the type of crimp cap 200, the second resilient member 15 and the return spring, and will not be described further herein.
