Description

Technical Field

[0001] This invention relates to the technical field of fuse processing, and in particular to a vibratory sand filling device and sand filling machine. Background Technology

[0002] A fuse is an electrical device that breaks the circuit by melting the fusible element when the current exceeds a specified value. It is widely used in high and low voltage power distribution systems, control systems, and electrical equipment. As a short-circuit and overcurrent protector, the fuse is one of the most commonly used protective devices. The fuse consists of an internal fusible element and quartz sand. Quartz sand has good thermal conductivity and insulation properties, which can play a role in explosion prevention and arc extinguishing, preventing sparks from being generated during the process of the fusible element burning out during a load short circuit. The density of the quartz sand inside the fuse is an indicator that directly affects the quality of fuse production.

[0003] In existing technologies, fuses are typically filled with quartz sand using a vibratory sand filling device. However, most existing vibratory sand filling devices simply vibrate without eliminating the vibration stress generated during the vibration process. This vibration stress is transmitted to the inside of the fuse, causing the compacted quartz sand to become loose. As a result, the quartz sand inside the fuse cannot meet the required density, requiring manual intervention to repeatedly start and stop the device for filling to reduce the effect of vibration stress. However, this method has low processing efficiency, and manual intervention is difficult to control, making it impossible to ensure product quality. Furthermore, when multiple devices are independently assembled on the same equipment for sand filling, the vibration stress on the equipment is too high due to the joint vibration of multiple devices, which can easily affect the lifespan of various components within the equipment system. This issue urgently needs to be addressed. Summary of the Invention

[0004] To address the shortcomings of the prior art, this application provides a vibratory sand filling device that offers high processing efficiency, good production quality, and reduced vibration stress.

[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions:

[0006] A vibratory sand filling device includes a base, a support plate that is slidably disposed on the top of the base in a vertical direction, a vibratory motor that is fixedly installed on the bottom of the support plate, a slide seat for placing a fuse that is slidably disposed on the top of the support plate in a horizontal direction, and a sand filling mechanism for adding sand to the fuse that is disposed on the top of the base.

[0007] A horizontal buffer section is connected to the top of the support plate and is used to buffer the slide block;

[0008] A vertical buffer section is connected between the base and the support plate, and the vertical buffer section is used to buffer the support plate;

[0009] A clamping mechanism is connected to the slide block and is used to fix the fuse at an angle.

[0010] By adopting the above technical solution, during processing, the sand-adding mechanism can replenish the quartz sand inside the fuse. Since the vibrating motor is connected to the support plate and the slide block is slidably connected to the support plate, under the vibration of the vibrating motor, the support plate reciprocates vertically, and the slide block reciprocates horizontally on the support plate. At this time, the vertical buffer and the horizontal buffer respectively buffer and absorb energy for the vibrating support plate and the slide block, so as to reduce the vibration stress generated by the device in various directions during the vibration process. Furthermore, since the fuse is inclined under the action of the clamping mechanism, the quartz sand inside the fuse continuously collides with the inner wall of the fuse under the horizontal vibration of the slide block. This causes the quartz sand near the inner wall to be subjected to the downward reaction force of the inner wall of the fuse, thereby causing the quartz sand to continuously deposit downward. It can also reduce the upward vibration stress brought to the quartz sand by the vibration of the device, making it easier for the quartz sand to be distributed downward in the space of the fuse, improving the density of the quartz sand, and thus improving the processing efficiency and production quality of the vibrating sand-filling device.

[0011] In a preferred embodiment, the present application may be further configured such that: the clamping mechanism includes a fixing block and a clamping block, the fixing block is fixedly connected to the top of the slide block, the clamping block is slidably disposed on the top of the slide block, the sliding direction of the clamping block is the same as the sliding direction of the slide block, a first V-shaped groove is obliquely formed on one side of the fixing block near the clamping block, and a second V-shaped groove is formed on one side of the clamping block near the fixing block along the length direction of the first V-shaped groove, both the first V-shaped groove and the second V-shaped groove are used to abut against adjacent side walls of the fuse, and the slide block is provided with a pushing component for driving the clamping block to slide toward the fixing block.

[0012] By adopting the above technical solution, when the fuse is located between the first V-groove and the second V-groove, the clamping block is slid toward the fixing block by pushing the component, so that the side wall of the fuse abuts and cooperates with the first V-groove and the second V-groove to complete the clamping and fixing. Furthermore, since the first V-groove and the second V-groove are both inclined, the inclined fixing of the fuse can be achieved at the same time.

[0013] In a preferred embodiment, this application can be further configured as follows: the pushing assembly includes a push rod, a connector, and a rotating rod; an adjustment seat is provided on the top of the support plate; a handle is provided at one end of the rotating rod; the other end of the rotating rod is hinged to the top of the adjustment seat; one end of the connector is hinged to the side of the rotating rod near the adjustment seat; the other end of the connector is hinged to the push rod; the push rod is slidably disposed on the top of the adjustment seat; the sliding direction of the push rod is the same as the sliding direction of the slide block; and the push rod is fixedly connected to the side of the clamping block away from the fixed block.

[0014] By adopting the above technical solution, the push rod, the connector, and the rotating rod form a linkage mechanism. According to the principle of the linkage mechanism, the operator can control the horizontal sliding of the push rod by rotating it, thereby enabling the clamping block to slide away from or closer to the fixed block. Furthermore, when the three hinge points between the push rod, the connector, and the rotating rod are collinear, the linkage mechanism is in a dead position, preventing the clamping block from being pushed back by external force, thus playing a limiting role.

[0015] In a preferred embodiment, this application may be further configured such that: a plug-in groove is provided on one side of the rotating rod near the adjusting seat, and when the hinge points between the push rod, the connecting member and the rotating rod are collinear, the plug-in groove is plugged into the connecting member.

[0016] By adopting the above technical solution, when the linkage mechanism is in the dead position, the possibility of the rotating rod rotating under the action of external force can be reduced because the connecting part and the insertion slot are engaged, thereby further improving the limiting effect of the linkage mechanism.

[0017] In a preferred embodiment, this application can be further configured as follows: the support plate is provided with a guide rail along the sliding direction of the slide block, the adjusting seat is slidably connected to the guide rail, the guide rail is provided with a strip-shaped limiting hole along its own length direction, the adjusting seat is provided with a plurality of threaded holes corresponding to the position of the strip-shaped limiting hole, the adjusting seat is provided with a bolt, the bolt is threadedly engaged with the threaded hole and passes through the strip-shaped limiting hole, and the bottom end of the bolt is provided with an abutment nut, the abutment nut is threadedly engaged with the bolt and the size of the abutment nut is larger than the strip-shaped limiting hole.

[0018] By adopting the above technical solution, the operator can adjust the position of the adjusting seat on the guide rail according to the actual size of the fuse, thereby further increasing the stroke of the push rod driving the clamping block and improving the adaptability of the clamping mechanism to fuses of different sizes. At the same time, by inserting the bolt into the strip-shaped limiting hole and threading it with different threaded holes, and by threading the abutting nut with the bolt and pressing it against the bottom of the guide rail, the adjusting seat and the guide rail can be connected as one unit, thereby playing a limiting role for the adjusting seat.

[0019] In a preferred embodiment, this application can be further configured as follows: the horizontal buffer portion includes two opposing mounting plates, both of which are fixedly connected to the top of the support base. The slide is located between the two mounting plates. A plurality of first buffer units are provided between each mounting plate and the slide. The slide has a groove corresponding to each of the first buffer units. The first buffer unit includes a slide rod and a first spring. One end of the slide rod is fixedly connected to the mounting plate, and the other end of the slide rod slides in cooperation with the groove. The first spring is sleeved on the slide rod and fixedly connected between the bottom wall of the groove and the mounting plate.

[0020] By adopting the above technical solution, when the slide block is offset relative to the mounting plate, the bottom wall of the slide groove squeezes the first spring, realizing the buffer energy absorption of the horizontal buffer part. In addition, under the action of the sliding rod and the sliding groove, it can play a guiding role for the slide block, so that the first spring can only deform in one direction, ensuring the horizontal one-way buffer energy absorption effect.

[0021] In a preferred embodiment, this application can be further configured such that: the vertical buffer portion includes a plurality of second buffer units, which are evenly distributed between the base and the support plate; each second buffer unit includes a lifting sleeve, a lifting rod, and a second spring; the lifting sleeve is vertically fixedly installed on the base; the bottom end of the lifting rod slides in conjunction with the inside of the lifting sleeve; the top end of the lifting rod is fixedly connected to the support plate; and the second spring is coaxially sleeved on the lifting sleeve and the lifting rod and fixedly connected between the support plate and the base.

[0022] By adopting the above technical solution, when the support plate is offset relative to the base, the support plate compresses the second spring, realizing the buffering and energy absorption of the vertical buffer section. In addition, under the sliding cooperation of the lifting sleeve and the lifting rod, it can guide the support plate so that the second spring can only deform in one direction, ensuring the vertical unidirectional buffering and energy absorption effect. At the same time, the second spring is coaxially set with the lifting sleeve and the lifting rod, which can improve the synchronization rate between the displacement of the support plate and the deformation of the second spring, further improving the vertical buffering and energy absorption effect.

[0023] In a preferred embodiment, the present application may be further configured such that: the sand adding mechanism includes a sand adding bin, a conveying pipe, and a support rod for providing support to the sand adding bin; the bottom end of the support rod is vertically fixed to the top of the base; the sand adding bin is installed on the top of the support rod; the top of the sand adding bin is open and the bottom is provided with a discharge port; the two ends of the conveying pipe are respectively connected to the discharge port and the inlet of the fuse.

[0024] By adopting the above technical solution and setting up a sand filling chamber and a conveying pipe, quartz sand can be continuously filled into the fuse during the vibration of the fuse.

[0025] In a preferred embodiment, this application can be further configured as follows: the sand filling chamber is fixedly connected to a connecting plate, the top end of the support rod is provided with a threaded section, the connecting plate is provided with a through hole for the threaded section to pass through, the threaded section is provided with two support nuts for threaded engagement with the threaded section, and the connecting plate is located between the two support nuts.

[0026] By adopting the above technical solution, rotating the two support nuts allows them to move on the threaded section of the support rod and press against the upper and lower sides of the connecting plate, thereby completing the installation of the sand filling chamber. The structure is simple and practical, and the height of the sand filling chamber can be adjusted by changing the position of the support nuts, which can regulate the vertical flow speed of the quartz sand.

[0027] Another object of this application is to provide a sand filling machine, including a machine base, a sand storage device, and a plurality of vibratory sand filling devices as described in any one of claims 1-9. The sand storage device is located directly above the machine base. A turntable is rotatably mounted on the machine base. A motor is mounted on the bottom of the turntable. The output shaft of the motor is coaxially and fixedly connected to the turntable. The plurality of vibratory sand filling devices are uniformly and fixedly mounted on the turntable along the circumference of the turntable. The sand storage device is used to transport quartz sand into the sand filling bin of the vibratory sand filling device.

[0028] By adopting the above technical solution, a turntable, a motor, several vibratory sand filling devices and a sand storage device are set up to form a sand filling production line. Since each of the above-mentioned vibratory sand filling devices can reduce the vibration stress generated by the device in various directions during the vibration process through the vertical buffer and horizontal buffer, the vibration stress on the machine platform and turntable will also be greatly reduced, thereby reducing the overall wear and tear of the sand filling machine and improving the stability and durability of the equipment.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Since the vibratory motor is connected to the support plate and the slide block is slidably connected to the support plate, under the vibration of the vibratory motor, the support plate reciprocates vertically, and the slide block reciprocates horizontally on the support plate. At this time, the vertical buffer part and the horizontal buffer part respectively buffer and absorb energy for the vibrating support plate and slide block, so as to reduce the vibration stress generated by the device in various directions during the vibration process. In addition, since the fuse is inclined under the action of the clamping mechanism, the quartz sand inside the fuse continuously collides with the inner wall of the fuse under the horizontal vibration of the slide block. This causes the quartz sand near the inner wall to be subjected to the downward reaction force of the inner wall of the fuse, so that the quartz sand continuously deposits downward. This also reduces the upward vibration stress brought to the quartz sand by the device vibration, making it easier for the quartz sand to be distributed downward in the space of the fuse, improving the density of the quartz sand, and thus improving the processing efficiency and production quality of the vibratory sand filling device.

[0031] 2. When the fuse is located between the first V-groove and the second V-groove, the clamping block is slid toward the fixing block by pushing the component, so that the side wall of the fuse abuts and cooperates with the first V-groove and the second V-groove to complete the clamping and fixing. Since the first V-groove and the second V-groove are both inclined, the inclined fixing of the fuse can be achieved at the same time.

[0032] 3. The push rod, connector, and rotating rod form a linkage mechanism. According to the principle of linkage mechanism, the operator can control the horizontal sliding of the push rod by rotating it, so as to make the clamping block slide away from or close to the fixed block. When the three hinge points between the push rod, connector, and rotating rod are collinear, the linkage mechanism is in a dead position, preventing the clamping block from driving the push rod to push back under the action of external force, thus playing a limiting role.

[0041] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0042] A vibratory sand-filling device according to Embodiment 1 of this application is described below with reference to the accompanying drawings.

[0043] like Figure 1As shown, the vibratory sand filling device includes a base 1, which provides support for the various components above. A support plate 2 is slidably mounted on the top of the base 1 in the vertical direction. Both the base 1 and the support plate 2 are cuboids to increase the support area. A vibratory motor 3 is fixedly installed at the bottom of the support plate 2. A slide block 5 for placing a fuse 4 is slidably mounted on the top of the support plate 2 in the horizontal direction. A sand filling mechanism 6 for adding sand to the fuse 4 is provided on the top of the base 1.

[0044] The sand-adding mechanism 6 includes a sand-adding bin 61, a conveying pipe 62, and a support rod 63 for supporting the sand-adding bin 61. The bottom end of the support rod 63 is vertically fixed to the top of the base 1. The sand-adding bin 61 is installed on the top of the support rod 63. The sand-adding bin 61 is cylindrical in shape with an opening at the top and a funnel-shaped bottom end with a discharge port to facilitate the discharge of quartz sand and prevent clogging. The two ends of the conveying pipe 62 are connected to the discharge port and the inlet of the fuse 4, respectively. By setting up the sand-adding bin 61 and the conveying pipe 62, quartz sand can be continuously filled into the fuse 4 during the vibration of the fuse 4.

[0045] Furthermore, the sand filling chamber 61 is fixedly connected to a connecting plate 7, and the top of the support rod 63 is provided with a threaded section 8. The connecting plate 7 has a through hole 9 for the threaded section 8 to pass through. The threaded section 8 is provided with two support nuts 10 for threaded engagement with the threaded section 8. The connecting plate 7 is located between the two support nuts 10. By rotating the two support nuts 10, they can be moved on the threaded section 8 of the support rod 63 and pressed against the upper and lower sides of the connecting plate 7 respectively, thereby completing the installation of the sand filling chamber 61. The structure is simple and practical, and the height of the sand filling chamber 61 can be adjusted by changing the position of the support nuts 10, which can play a role in adjusting the vertical flow speed of the quartz sand.

[0046] Under the vibration of the vibrating motor 3, the support plate 2 will slide back and forth in the vertical direction, and the slide block 5 will slide back and forth on the support plate 2 in the horizontal direction. In order to buffer and absorb energy for the slide block 5 and the support plate 2, a horizontal buffer part 11 for buffering the slide block 5 is provided on the top of the support plate 2, and a vertical buffer part 13 for buffering the support plate 2 is provided between the base 1 and the support plate 2.

[0047] Among them, such as Figure 1 and Figure 2As shown, the horizontal buffer section 11 includes two opposing mounting plates 111, both of which are fixedly connected to the top of the support base. The slide block 5 is located between the two mounting plates 111. A plurality of first buffer units 112 are provided between each mounting plate 111 and the slide block 5. The slide block 5 has a groove 12 corresponding to each first buffer unit 112. The first buffer unit 112 includes a slide rod 1121 and a first spring 1122. One end of the slide rod 1121 is fixedly connected to the mounting plate 111, and the other end of the slide rod 1121 is connected to the groove. 12. Sliding engagement: The first spring 1122 is sleeved on the slide rod 1121 and fixedly connected between the inner bottom wall of the slide groove 12 and the mounting plate 111. Here, when the slide block 5 is offset relative to the mounting plate 111, the inner bottom wall of the slide groove 12 compresses the first spring 1122, realizing the buffering energy absorption of the horizontal buffer part 11. Under the sliding engagement of the slide rod 1121 and the slide groove 12, it can play a guiding role for the slide block 5, so that the first spring 1122 can only deform in one direction, ensuring the horizontal one-way buffering energy absorption effect.

[0048] In addition, such as Figure 1 As shown, the vertical buffer section 13 includes several second buffer units 131, which are evenly distributed between the base 1 and the support plate 2. Each second buffer unit 131 includes a lifting sleeve 1311, a lifting rod 1312, and a second spring 1313. The lifting sleeve 1311 is vertically fixed to the base 1. The bottom end of the lifting rod 1312 slides within the lifting sleeve 1311, and the top end of the lifting rod 1312 is fixedly connected to the support plate 2. The second spring 1313 is coaxially sleeved between the lifting sleeve 1311 and the lifting rod 1312 and is fixedly connected between the support plate 2 and the base 1. When the support plate 2 is offset relative to the base 1, the support plate 2 compresses the second spring 1313, realizing the buffering and energy absorption of the vertical buffer part 13. Under the sliding cooperation of the lifting sleeve 1311 and the lifting rod 1312, it can guide the support plate 2 so that the second spring 1313 can only deform in one direction, ensuring the effect of vertical unidirectional buffering and energy absorption. At the same time, the second spring 1313 is coaxially set with the lifting sleeve 1311 and the lifting rod 1312, which can improve the synchronization rate between the displacement of the support plate 2 and the deformation of the second spring 1313, further improving the effect of vertical buffering and energy absorption.

[0049] It should be noted that in this embodiment, the number of the first buffer unit 112 and the second buffer unit 131 are both four. The four first buffer units 112 are respectively located at the two ends of opposite sides of the slide 5, and the four second buffer units 131 are respectively located at the four corners of the bottom of the support plate 2. While realizing buffering and energy absorption, it improves the stability of the installation of the base 1 and the support. The number of the first buffer unit 112 and the second buffer unit 131 can be set according to the actual vibration stress generated by the slide 5 during vibration.

[0050] Reference Figure 1 and Figure 3 To facilitate the installation of the fuse 4, a clamping mechanism 14 for tilting and fixing the fuse 4 is provided on the top of the slide block 5. Here, the sand-adding mechanism 6 replenishes the quartz sand inside the fuse 4. Since the vibration motor 3 is connected to the support plate 2 and the slide block 5 is slidably connected to the support plate 2, under the vibration of the vibration motor 3, the support plate 2 reciprocates vertically, and the slide block 5 reciprocates horizontally on the support plate 2. At this time, the vertical buffer part 13 and the horizontal buffer part 11 respectively buffer and absorb energy from the vibrating support plate 2 and slide block 5 to reduce energy loss during vibration. The device generates vibration stress in all directions. Because the fuse 4 is tilted under the action of the clamping mechanism 14, the quartz sand inside the fuse 4 continuously collides with the inner wall of the fuse 4 under the horizontal vibration of the slide block 5. This causes the quartz sand near the inner wall to be subjected to the downward reaction force of the inner wall of the fuse 4, thereby causing the quartz sand to continuously deposit downward. It can also reduce the upward vibration stress on the quartz sand caused by the device vibration, so that the quartz sand can be more easily distributed downward in the space of the fuse 4, improving the density of the quartz sand, and thus improving the processing efficiency and production quality of the vibratory sand filling device.

[0051] Among them, such as Figure 1 and Figure 3 As shown, to achieve the tilted fixation of the fuse 4, the clamping mechanism 14 includes a fixing block 141 and a clamping block 142. The fixing block 141 is fixedly connected to the top of the slide block 5, and the clamping block 142 is slidably disposed on the top of the slide block 5. The sliding direction of the clamping block 142 is the same as the sliding direction of the slide block 5. A first V-shaped groove 15 is obliquely formed on the side of the fixing block 141 near the clamping block 142, and a second V-shaped groove 16 is formed on the side of the clamping block 142 near the fixing block 141 along the length direction of the first V-shaped groove 15. The first V-shaped groove 15 and the second V-shaped groove Both 16 are used to abut against the adjacent side walls of the fuse 4. The slide block 5 is provided with a pushing component 17 for driving the clamping block 142 to slide towards the fixing block 141. When the fuse 4 is located between the first V-groove 15 and the second V-groove 16, the pushing component 17 slides the clamping block 142 towards the fixing block 141, so that the side walls of the fuse 4 abut against the first V-groove 15 and the second V-groove 16 to complete the clamping and fixing. Since the first V-groove 15 and the second V-groove 16 are both inclined, the inclined fixing of the fuse 4 can be achieved at the same time.

[0052] It should be noted that in this embodiment, the angle formed by the inner walls on both sides of the first V-groove 15 and the angle formed by the inner walls on both sides of the second V-groove 16 are both 90°, so as to adapt to most cuboid fuses 4 on the market. The angle formed by the inner walls on both sides of the first V-groove 15 and the second V-groove 16 can be set according to the shape of the fuse 4, and is not limited by the size of the fuse 4. The first V-groove 15 and the second V-groove 16 with the same angle can be adapted to fuses 4 of the same shape but different specifications. The structure is simple and highly applicable.

[0053] Furthermore, such as Figure 1 and Figure 4 As shown, to achieve the sliding connection between the clamping block 142 and the slide block 5, the pushing assembly 17 includes a push rod 171, a connector 172, and a rotating rod 173. An adjusting seat 18 is provided on the top of the support plate 2. A handle 19 is provided at one end of the rotating rod 173, and the other end of the rotating rod 173 is hinged to the top of the adjusting seat 18. One end of the connector 172 is hinged to the side of the rotating rod 173 near the adjusting seat 18, and the other end of the connector 172 is hinged to the push rod 171. The push rod 171 is slidably positioned on the top of the adjusting seat 18, and the sliding direction of the push rod 171 is the same as the sliding direction of the slide block 5. Similarly, push rod 171 is fixedly connected to the side of clamping block 142 away from fixed block 141. In order to make the sliding direction of push rod 171 the same as the sliding direction of slide block 5, the adjusting seat 18 is provided with mounting plate 20. The mounting plate 20 is provided with directional limiting hole 21. The axial direction of directional limiting hole 21 is the same as the sliding direction of slide block 5, and the size of directional limiting hole 21 is adapted to the size of push rod 171. Push rod 171 passes through directional limiting hole 21. Under the limiting action of directional limiting hole 21, the sliding direction of push rod 171 can be kept unchanged.

[0054] Here, the push rod 171, the connector 172, and the rotating rod 173 form a linkage mechanism. According to the principle of the linkage mechanism, the operator can control the horizontal sliding of the push rod 171 by rotating it, thereby enabling the clamping block 142 to slide away from or near the fixed block 141. When the three hinge points between the push rod 171, the connector 172, and the rotating rod 173 are collinear, the linkage mechanism is in a dead position, preventing the clamping block 142 from driving the push rod 171 to push back under the action of external force, thus playing a limiting role.

[0055] Furthermore, such as Figure 4As shown, a slot 22 is provided on the side of the rotating rod 173 near the adjusting seat 18. When the hinge points of the push rod 171, the connector 172 and the rotating rod 173 are collinear, the slot 22 and the connector 172 are engaged. When the linkage mechanism is in the dead position, the engagement of the connector 172 and the slot 22 reduces the possibility of the rotating rod 173 rotating under external force, thereby further improving the limiting effect of the linkage mechanism. In this embodiment, the connector 172 is arc-shaped, and the arc of the connector 172 faces the slot 22 to increase the contact area between the connector 172 and the slot 22, thereby enhancing the engagement effect.

[0056] In addition, such as Figure 1 As shown, to further improve the adaptability of the clamping mechanism 14 to fuses 4 of different sizes, the support plate 2 is provided with a guide rail 23 along the sliding direction of the slide block 5. The adjusting seat 18 is slidably connected to the guide rail 23. The guide rail 23 has a strip-shaped limiting hole 24 along its own length. The adjusting seat 18 has multiple threaded holes 25 corresponding to the positions of the strip-shaped limiting holes 24. The adjusting seat 18 is provided with a bolt 26. The bolt 26 is threaded with the threaded hole 25 and passes through the strip-shaped limiting hole 24. The bottom end of the bolt 26 is provided with an abutment nut 27. The abutment nut 27 is threaded with the bolt 26 and the abutment nut 27 is large in size. At the strip-shaped limiting hole 24, the operator can adjust the position of the adjusting seat 18 on the guide rail 23 according to the actual size of the fuse 4, thereby further increasing the stroke of the push rod 171 driving the clamping block 142 and improving the adaptability of the clamping mechanism 14 to fuses 4 of different sizes. At the same time, by inserting the bolt 26 into the strip-shaped limiting hole 24 and threading it with different threaded holes 25, and by threading the abutting nut 27 with the bolt 26 and pressing it against the bottom of the guide rail 23, the adjusting seat 18 and the guide rail 23 can be connected as one unit, thereby limiting the position of the adjusting seat 18.

[0057] The implementation principle of the vibratory sand filling device in Embodiment 1 of this application is as follows: First, the fuse 4 to be filled with sand is placed between the fixing block 141 and the clamping block 142. The rotating rod 173 is rotated so that the push rod 171 drives the clamping block 142 to slide close to the fuse 4, so that the first V-groove 15 and the second V-groove 16 respectively abut against different adjacent side walls of the fuse 4, completing the tilting fixation of the fuse 4. Then, after the sand filling mechanism 6 completes the filling of quartz sand inside the fuse 4, the vibration motor 3 is started. At this time, the vertical buffer part 13 and the horizontal buffer part 11 respectively support the vibrating support plate. 2 and slide 5 buffer and absorb energy to reduce the vibration stress generated in various directions during the vibration process. The quartz sand inside the fuse 4 continuously collides with the inner wall of the fuse 4 under the horizontal vibration of the slide 5. This causes the quartz sand near the inner wall to be subjected to the downward reaction force of the inner wall of the fuse 4, which causes the quartz sand to continuously deposit downward. It can also reduce the upward vibration stress on the quartz sand caused by the vibration of the device, so that the quartz sand can be more easily distributed downward in the space of the fuse 4, improving the density of the quartz sand, and thus improving the processing efficiency and production quality of the vibratory sand filling device.

[0058] Example 2

[0059] like Figure 5 As shown, a sand-filling machine includes a machine base 28, a sand storage device 29, and several of the aforementioned vibratory sand-filling devices. The sand storage device 29 is located directly above the machine base 28. A turntable 30 is rotatably mounted on the machine base 28. A motor 31 is mounted at the bottom of the turntable 30, and the output shaft of the motor 31 is coaxially and fixedly connected to the turntable 30. Several of the aforementioned vibratory sand-filling devices are evenly and fixedly mounted on the top of the turntable 30 along the circumference of the turntable 30. Typically, the vibratory sand-filling devices can be fixedly mounted on the top of the turntable 30 by means of threaded connection. In this embodiment, several rubber shock-absorbing blocks 32 are also provided at the bottom of the base 1 of the vibratory sand-filling device. When the vibratory sand-filling device is mounted on the turntable 30, the rubber shock-absorbing blocks 32 are used to abut against the base 1 and... The turntable 30 is used to improve the buffering and energy absorption effect. The sand storage device 29 is used to transport quartz sand to the sand filling bin 61 of the vibratory sand filling device. The specific structure of the vibratory sand filling device has been described in detail in Embodiment 1, so it will not be repeated here. By setting the turntable 30, motor 31, several vibratory sand filling devices and sand storage device 29, a sand filling production line can be formed. Since each of the above-mentioned vibratory sand filling devices can reduce the vibration stress generated by the device in various directions during vibration through the vertical buffer part 13 and the horizontal buffer part 11, the vibration stress on the machine platform 28 and the turntable 30 will also be greatly reduced, thereby reducing the overall wear of the sand filling machine and improving the stability and durability of the equipment.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
