Description

Technical Field

[0001] The utility model relates to the technical field of a pressurizing device for a fusion splicer, in particular to a quick-disassembly device with pressure-limiting, guiding and pressurizing functions for a high-frequency fusion splicer. Background Art

[0002] A high-frequency fusion splicer uses a high-frequency electric field to cause internal molecules of plastics to oscillate and generate heat energy for fusing various products. Under the action of the high-frequency electric field, dielectric materials activate positive charged molecules, causing the positive charged molecules of the dielectric materials to move at high speed and generate heat by friction, thereby fusing plastics.

[0003] During the pressurizing process of the fusion splicer, the stroke of the mold closing process is large and the thrust is small, and its stroke accounts for more than 90% of the total stroke. The pressurizing process has a small stroke and a large thrust. The existing workpiece pressurizing device only uses a mechanical transmission mechanism for mold closing and pressurizing. Due to space and mechanism limitations, it is difficult to achieve the best labor-saving effect, and it is very laborious to use.

[0004] In the patent document with the Chinese patent application number 202223533485.X and the publication date of September 8, 2323, a torsion lever pressurizing device is disclosed, which includes a frame, a lever linkage device and a pressurizing mechanism. One end of the lever linkage device is connected to the pressurizing mechanism, and the other end of the lever linkage device is connected to a pressurizing member. The lever linkage device drives the pressurizing member to close the mold, and the pressurizing mechanism jacks up the lever linkage device to pressurize the pressurizing member; the rotation direction of the eccentric transmission member is the same as the swinging direction of the second swing rod; during the rotation of the eccentric transmission member, the swinging of the lever linkage device is restricted.

[0005] This document drives the pressurizing member through the lever linkage device to achieve mold closing. Although the swinging method of the lever is simple and practical, if the swinging amplitude of the swing rod is too large, it is easy to cause the degree of pressing the workpiece by the pressurizing member to increase and damage the workpiece. The above document restricts the swinging amplitude of the swing rod by setting a limiting device. Although this can limit the swing rod, the limiting device is fixedly installed on the frame. In this way, if it is necessary to adjust the swinging amplitude of the swing rod, it is necessary to remove the frame to take out the limiting device. Therefore, it will cause inconvenience for actual use. Summary of the Invention

[0006] The utility model provides a quick-disassembly device with pressure-limiting, guiding and pressurizing functions for a high-frequency fusion splicer, which can quickly disassemble the limiting device, so as to facilitate the adjustment of the swinging amplitude of the swing rod during use, and has high processing efficiency.

[0007] To achieve the above object, the technical solution of the present utility model is: a pressurizing limit guiding quick-release device for a high-frequency welder, which is arranged on the frame of the welder and is used to limit the lever linkage device of the welder. The lever linkage device is movably arranged on the frame and includes a first swing rod and a second swing rod. The first swing rod and the second swing rod are swingably arranged on the frame through the pressurizing mechanism of the welder, and include a limiting device, which limits the swinging first swing rod and second swing rod; the limiting device includes a limiting sleeve, a limiting rod and a limiting component. The limiting component is detachably arranged on the limiting rod, and the limiting rod is connected to the frame through the limiting component. A limiting sleeve is sleeved outside the limiting rod, and the limiting sleeve contacts the second swing rod and abuts against the second swing rod.

[0008] In the above structure, by arranging a limiting device between the first swing rod and the second swing rod, the limiting device limits the swinging amplitude of the swinging first swing rod and second swing rod, so as to prevent the swinging amplitude of the first swing rod and the second swing rod from being too large. And the limiting rod is connected to the frame through the limiting component. When it is necessary to disassemble the limiting device, by releasing the limiting component, the limiting rod can be disengaged from the frame, thereby repairing or replacing the limiting sleeve. For example, if it is necessary to reduce the swinging angle, it can be achieved by replacing the limiting sleeve with a larger outer wall diameter, so that the limiting device can be replaced according to actual needs, which is convenient to adjust the swinging amplitude of the swing rod during use, resulting in high processing efficiency. In addition, through the limiting sleeve, the swinging of the first swing rod and the second swing rod will not damage the limiting rod, and the replacement can be achieved only by replacing the limiting sleeve, with higher reliability.

[0009] Further, a first bracket and a second bracket are arranged on the frame. The second swing rod is connected between the first bracket and the second bracket through a pressurizing mechanism. Mounting holes are correspondingly arranged on the first bracket and the second bracket. The limiting rod passes through the mounting holes and is arranged on the first bracket and the second bracket. One end of the limiting rod is located outside the first bracket, and the other end of the limiting rod is located outside the second bracket. The middle part of the limiting rod is located between the first bracket and the second bracket. A limiting sleeve is sleeved on the middle part of the limiting rod, and the limiting component is arranged at both ends of the limiting rod and limits the setting of the limiting rod.

[0010] With the above setting, by passing the limiting rod through the first bracket and the second bracket, a limiting sleeve is sleeved on the middle part of the limiting rod, so that the swinging amplitude of the second swing rod is controlled by the limiting sleeve during use.

[0011] Further, the limiting component includes a split pin. Through holes penetrating from one side of the limiting rod to the other side are arranged at both ends of the limiting rod. The split pin is inserted into the through hole and abuts against the outer side walls of the first bracket and the second bracket.

[0012] With the above settings, when the limit device needs to be disassembled through the limit component, by removing the split pin from the through hole, the connection between the limit rod and the first bracket and the second bracket can be released, and then the limit rod can be pulled out, thus realizing the quick disassembly of the limit device, with a simple and reliable structure.

[0013] Furthermore, the limit sleeve is movably sleeved on the middle part of the limit rod.

[0014] With the above settings, the limit sleeve is not fixedly connected to the limit rod, so that it is convenient to pull the limit rod out of the first bracket and the second bracket when disassembling the limit device.

[0015] Furthermore, a gasket is also provided between the split pin and the outer side walls of the first bracket and the second bracket.

[0016] With the above settings, the gasket prevents the split pin from directly contacting the first bracket and the second bracket, thus facilitating the removal of the split pin.

[0017] Furthermore, the lever linkage device further includes a pedal, a connecting rod, a pull rod, a straight rod and a cross rod; one end of the pedal is hinged to the frame, the pedal is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to one end of the first swing rod, and one end of the first swing rod close to the connecting rod is hinged to one end of the second swing rod; the other end of the second swing rod is rotatably connected between the first bracket and the second bracket through a pressurizing mechanism, the other end of the first swing rod is hinged to the pull rod and one end of the straight rod, the other end of the straight rod is hinged to one end of the cross rod, and the cross rod is rotatably arranged on the frame; a pressing member is connected to the other end of the cross rod.

[0018] With the above settings, the connecting rod drives the first swing rod and the second swing rod to swing; the first swing rod and the second swing rod push the straight rod to rise, the straight rod pushes the cross rod to swing, and the cross rod drives the pressing member to press down; the pressing member is brought into contact with the workpiece.

[0024] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] As Figures 1 to 5 shown, a pressure-limiting guiding quick-release device for a high-frequency welding machine is used to be arranged on the welding machine. The welding machine includes a frame 1. The pressure-limiting guiding disassembly device includes a lever linkage device 2. The lever linkage device 2 is movably arranged on the frame 1. The lever linkage device 2 includes a pedal 21, a connecting rod 22, a first swing rod 23, a second swing rod 24, a pull rod 25, a straight rod 26 and a cross rod 27. One end of the pedal 21 is hinged to the frame 1. One end of the pedal 21 is hinged to one end of the connecting rod 22. The other end of the connecting rod 22 is hinged to one end of the first swing rod 23. The end of the first swing rod 23 close to the connecting rod 22 is hinged to one end of the second swing rod 24. The other end of the second swing rod 24 is rotatably connected to the frame through a pressurizing mechanism 11. The other end of the first swing rod 23 is hinged to the pull rod 25 and one end of the straight rod 26. The other end of the straight rod 26 is hinged to one end of the cross rod 27. The cross rod 27 is rotatably arranged on the frame 1. A pressing member (not shown in the figure) is connected to the other end of the cross rod 27. The connecting rod 22 drives the first swing rod 23 and the second swing rod 24 to swing. The first swing rod 23 and the second swing rod 24 push the straight rod 26 to rise. The straight rod 26 pushes the cross rod 27 to swing. The cross rod 27 drives the pressing member to press down. When the pressing member contacts the workpiece, in this embodiment, the pressurizing mechanism is a prior art, and it is specifically disclosed in the patent document with the application number 202223533485.X and the publication date of September 8, 2323, and will not be repeated here.

[0026] A limiting device 3 is arranged on the frame 1. The limiting device 3 limits the swinging first swing rod 23 and second swing rod 24. The limiting device 3 includes a limiting sleeve 31, a limiting rod 32 and a limiting member 33. The limiting rod 32 is restrictedly connected to the frame 1 through the limiting member 33. A limiting sleeve 31 is sleeved outside the limiting rod 33. The limiting sleeve 31 contacts the second swing rod 22 and the limiting sleeve 31 abuts against the second swing rod 24. In this embodiment, two lever linkage devices are provided and are respectively arranged on both sides of the frame. Two limiting devices are provided and respectively correspond to the second swing rods on both sides of the frame.

[0027] As Figure 3As shown in the figure, a first bracket 12 and a second bracket 13 are provided on the frame 1. The second swing rod 24 is connected between the first bracket 12 and the second bracket 13 through a pressurizing mechanism 11. The limiting rod 32 is inserted through the first bracket 12 and the second bracket 13. One end of the limiting rod 32 is located outside the first bracket 12, the other end of the limiting rod 32 is located outside the second bracket 13, and the middle part of the limiting rod 32 is located between the first bracket 12 and the second bracket 13. A limiting sleeve 31 is sleeved on the middle part of the limiting rod 32. The limiting member 33 is arranged at both ends of the limiting rod 32 and restricts the setting of the limiting rod 32. In this embodiment, mounting holes 10 are respectively provided on the first bracket 12 and the second bracket 13. Both ends of the limiting rod 32 respectively pass through the mounting holes 10. By inserting the limiting rod 32 through the first bracket 12 and the second bracket 13, the limiting sleeve 31 is sleeved on the middle part of the limiting rod 32. Thus, when in use, the second swing rod 24 is restricted by the limiting sleeve 31, thereby controlling the swing amplitude of the second swing rod 24.

[0028] As Figure 3 shown, the limiting member 33 includes a split pin. Through holes 321 penetrating from one side of the limiting rod 32 to the other side are provided at both ends of the limiting rod 32. The split pin is inserted into the through holes 321 and the split pin abuts against the outer side walls of the first bracket 12 and the second bracket 13. In this embodiment, when the split pin is fixed, the two feet of the split pin are inserted and passed through the through holes, and one of the feet passing through the through holes is bent. Thus, the other foot of the split pin can be bent and arranged on the limiting rod and is not parallel to the extending direction of the through holes, so as to block the limiting rod from sliding out of the through holes, thereby fixing the limiting rod on the through holes to achieve fixation. When it needs to be removed, only the bent foot of the split pin needs to be straightened again, and thus the split pin can be taken out. The split pin is a common existing technology and will not be elaborated here. Through the limiting member 33, when the limiting device 3 needs to be disassembled, by taking out the split pin from the through holes 321, the connection between the limiting rod 32 and the first bracket 12 and the second bracket 13 can be released, and thus the limiting rod 32 can be pulled out, thereby realizing the rapid disassembly of the limiting device 3, with a simple and reliable structure.

[0029] The limiting sleeve 31 is movably sleeved on the middle part of the limiting rod 32. The above setting enables the limiting sleeve 31 not to be fixedly connected to the limiting rod 32, so that it is convenient to pull out the limiting rod 32 from the first bracket 12 and the second bracket 13 when disassembling the limiting device 3.

[0030] As Figure 3 shown, a gasket 34 is further provided between the split pin and the outer side walls of the first bracket 12 and the second bracket 13. The gasket 34 is used to prevent the split pin from directly contacting the first bracket 12 and the second bracket 13, thus facilitating the removal of the split pin.

[0031] Working principle of the utility model: By arranging a limiting device 3 between the first swing rod 23 and the second swing rod 34, the limiting device 3 limits the swing amplitude of the swinging first swing rod 23 and second swing rod 34, thereby preventing the swing amplitudes of the first swing rod 23 and the second swing rod 34 from being too large. Moreover, the limiting rod 32 is connected to the frame 1 through a limiting component 33. When it is necessary to disassemble the limiting device 3, by releasing the limiting component, the limiting rod 32 can be disengaged from the frame 1, thereby repairing or replacing the limiting sleeve 31. For example, if it is necessary to reduce the swing angle, it can be achieved by replacing the limiting sleeve 31 with a larger outer diameter, so that the limiting device 3 can be replaced according to actual needs, thus facilitating the adjustment of the swing amplitude of the swing rod during use, resulting in high processing efficiency. In addition, the limiting sleeve 31 prevents the swings of the first swing rod 23 and the second swing rod 34 from damaging the limiting rod 32, and the replacement can be achieved only by replacing the limiting sleeve 31, with higher reliability.
