The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The embodiment of the invention discloses a shell disassembling device, as shown in fig. 1, the disclosed disassembling device comprises a workbench 100, a left upright post 210 slidably arranged at one end of the workbench 100, a right upright post 220 slidably arranged at the other end of the workbench 100, and a group of pull claw assemblies 300 respectively arranged at opposite sides of the left upright post 210 and the right upright post 220. Before operation, two sides of the housing 700 may be pre-processed with a disassembling groove 710; in operation, the housing 700 is placed between the left column 210 and the right column 220, and the finger ends of both sets of pull tab assemblies 300 are placed in the disassembly slots 710. The left column 210 and the right column 220 are driven to slide back, and the pulling claw assembly 300 is driven to pull the outer shell 700 from the disassembling groove 710 to two sides. The finger end of the pull tab assembly 300 is preferably an internal hook structure that mates with the break-out slot 710.
Specifically, a left driving member 410 may be coupled to the bottom of the left column 210 to drive the left column 210 to slide, and a right driving member 420 may be coupled to the bottom of the right column 220 to drive the right column 220 to slide. One side of the left upright column 210, which is away from the right upright column 220, is fixedly provided with a luffing support 500, and the left driving element 410 is arranged on the luffing support 500; a luffing support 500 is also fixedly arranged on the side of the right column 220 facing away from the left column 210, and the right drive 420 is arranged on the luffing support 500.
In the disclosed embodiment, the horn support 500 functions to adjust the amplitude of the drive member. In the assembly stage of the housing 700 and the pull claw assembly 300, in order to improve the assembly efficiency, a large-amplitude drive is adopted, and the left and right driving members respectively drive the left and right upright posts to move in opposite directions; in the initial stage of the disassembling operation, in order to improve the disassembling efficiency, a large-amplitude drive is adopted, and a left driving piece and a right driving piece respectively drive a left upright post and a right upright post to move in a large-amplitude opposite way; in the later stage of the disassembling operation, i.e. the stage that the shell body of the shell 700 is about to be torn, the large-amplitude driving is converted into small-amplitude driving for the parts in the protective shell, and the left driving piece and the right driving piece respectively drive the left upright post and the right upright post to move in a small-amplitude opposite way.
In the disclosed embodiment of the invention, as shown in fig. 4, a cross-shaped through hole can be provided on the luffing support 500 to engage with the perforated spindle 520 for luffing operation of the driving elements (left and right driving elements). Specifically, the luffing support 500 may be provided with a first through-hole 511 with a circular cross section and a second through-hole 512 with an elliptical cross section, wherein the axis of the first through-hole 511 and the central axis of the second through-hole 512 intersect perpendicularly, and the central axis of the second through-hole 512 is parallel to the sliding motion direction of the left column 210/the right column 220. The central axis of the second through hole 512 is located at the intersection of the minor axis and the major axis of the cross section thereof. A rotation shaft 520 in clearance fit with the first through hole 511 may be provided, and a third through hole 521 is provided on the rotation shaft 520. The third through hole 521 is disposed at a position and a size matching those of the second through hole 512, the diameter of the cross section of the third through hole 521 is smaller than the length of the short axis of the cross section of the second through hole 512, and the center point of the cross section of the third through hole 521 is located on the long axis of the cross section of the second through hole 512. That is, the axis of the third through hole 521 intersects the central axis of the second through hole 512 and perpendicularly intersects the axis of the first through hole 511.
Further, the driving member is provided with an external thread, and the third through hole 521 is provided with an internal thread, and the internal thread is matched with the external thread and can perform limit fit. One end of the driving member is a driving end, and the other end passes through the third through hole 521 and is rotatably connected to the bottom of the left/right column 210/220. It should be noted that the driving member passes through the third through hole 521 and also passes through the second through hole 512 and perpendicularly intersects the rotation shaft 520.
As shown in fig. 1, the driving end is driven to rotate, and the driving member moves towards or away from the left column 210/right column 220 connected with the driving member due to the threaded limit fit between the driving member and the third through hole 521, so that the left column 210/right column 220 connected with the driving member is driven to move greatly. As shown in fig. 2, the driving end is driven to swing reciprocally along the long axis direction of the cross section of the second through hole 512, and since the short axis and the long axis of the cross section of the second through hole 512 are both longer than the diameter of the driving element, the driving element can drive the rotating shaft 520 to slightly rotate in the first through hole 511, and at the same time, the connecting portion between the driving element and the left upright post 210/right upright post 220 is driven to slightly swing reversely, so as to further drive the left upright post 210/right upright post 220 to slightly move. The rotation and the swing of the driving end can be manually driven.
Further, a fourth through hole may be disposed at the bottom of the left column 210/the right column 220, the axis of the fourth through hole may coincide with the central axis of the second through hole 512, and one end of the driving member facing away from the driving end passes through the fourth through hole and is fastened by a nut 430 in a limiting manner.
Further, a sliding groove or a sliding rail can be arranged on the top surface of the workbench 100, and a sliding block matched with the sliding groove or the sliding rail is arranged at the bottom ends of the left upright post and the right upright post, wherein the sliding block and the sliding groove/the sliding rail form a sliding pair. Of course, in order to accommodate small amplitude movements of the left and right uprights, the slide rail or chute should be provided with a margin for slight swinging of the connecting portions of the left and right uprights connected to the connecting member.
In the embodiment disclosed in the present invention, the disassembling device further includes a connecting rod 600 to improve the motion stability of the left column 210 and the right column 220, specifically, a forward thread section and a reverse thread section are provided on the connecting rod 600, the forward thread section may be in limited connection with the top thread of the left column 210, the reverse thread section may be in limited connection with the top thread of the right column 220, and the rotating connecting rod 600 may drive the top of the left column and the right column to synchronously move in opposite directions or back. When the driving member drives the bottom of the left column 210 and/or the right column 220 to move substantially, the driving link 600 should drive the top of the left column 210 and/or the right column 220 to move substantially synchronously.
Further, in order to adapt to the amplitude-variable movement of the left and right upright posts, the top ends of the left and right upright posts are respectively and fixedly provided with an amplitude-variable support 500, and the specific structure of the amplitude-variable support 500 is the same as that of the amplitude-variable support 500 fixedly arranged on the workbench 100 and used for supporting the driving element in any embodiment described above, which is not described in detail in this embodiment. In addition, the internal threads in the third through hole 521 of the luffing support 500 at the top of the left column 210 are matched with the forward threaded section of the connecting rod 600 and can be in limit fit, and the internal threads in the third through hole 521 of the luffing support 500 at the top of the right column 220 are matched with the reverse threaded section of the connecting rod 600 and can be in limit fit; both ends of the connecting rod 600 may be screwed into the luffing supports 500 at the top of the left and right uprights, respectively. When the bottoms of the left and right columns move by a small extent, the connecting rod 600 is not rotated, as shown in fig. 2, at this time, the left and right columns rotate in opposite directions or backward by a small extent around the axis of the rotating shaft 520 at the top of the left and right columns, so as to prevent the housing 700 from being scratched and the instantaneous reaction force from being excessively large, and damage the parts in the housing.
In the disclosed embodiment of the invention, as shown in fig. 1 and 3, the disclosed disassembling device further comprises a height adjusting assembly for adjusting the height of the pull claw assembly 300. The height adjusting assembly may include a support plate 810 and an adjusting lever 820 fixed to the left/right columns 210/220, and the pulling jaw assembly 300 may include a pulling jaw seat 310 and two pulling jaws 320 having opposite finger ends. Specifically, a forward thread section and a reverse thread section are arranged on the adjusting rod 820, a first threaded hole in limit fit with the forward thread section is arranged on the support plate 810, a second threaded hole in limit fit with the reverse thread section is arranged on the pull jaw seat 310, and after the adjusting rod 820 is screwed into the first threaded hole and the second threaded hole, the height of the pull jaw seat 310 is adjusted by rotating the adjusting rod 820. Two pull claws 320 are hinged on the pull claw seat 310, and the two pull claws 320 can be in limit connection through a limit rod 330.
Further, the limiting rod 330 may be provided with a forward thread section and a reverse thread section, one of the pull claws 320 is provided with a third threaded hole matched with the forward thread section, the other pull claw 320 is provided with a fourth threaded hole matched with the reverse thread section, the limiting rod 330 passes through the third threaded hole and the fourth threaded hole and is in limiting fit with the two pull claws 320, and the distance between the two pull claws 320 can be adjusted by rotating the limiting rod 330 so as to adapt to the shells 700 with various sizes.
In the embodiment disclosed in the invention, the soft pad 110 can be arranged on the top of the workbench 100, the shell 700 is placed on the soft pad 110 during operation, especially when the shell 700 is torn in the process of operation, the shell 700 is buffered, and the inner parts are protected.
