Description

Technical Field

[0001] This disclosure relates to the field of sleeve installation and aircraft component maintenance technology, and in particular to a sleeve disassembly and assembly tool and a sleeve replacement device. Background Technology

[0002] In the field of aircraft manufacturing and maintenance, sleeves, as key assembly tool accessories, are mainly used for the precise installation, disassembly, and inspection of fasteners to ensure the safety and reliability of aircraft structures.

[0003] Existing sleeves come in different types, such as the slotted sidewall sleeve disclosed in patent number CN208946032U, and the sleeve head in a refrigerant recovery torque air screwdriver tooling device disclosed in patent number CN204658295U. Currently, some companies still manually disassemble and assemble sleeves one by one, which results in a long overall time required for disassembly and assembly, and low overall process efficiency. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a sleeve disassembly and assembly tool and sleeve replacement equipment that can automatically clamp, disassemble and assemble sleeves by adjusting the height, and disassemble and assemble sleeves in groups to improve disassembly and assembly efficiency.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A sleeve disassembly and assembly tool includes multiple sleeve disassembly and assembly mechanisms. Each sleeve disassembly and assembly mechanism includes a clamping device, a rotary lifting drive cylinder, a sleeve mounting assembly, a guide rod, and a mounting plate. The clamping device includes a horizontal slide rail, a clamping cylinder, and two clamping jaws. The clamping cylinder and the horizontal slide rail are both mounted on the mounting plate. The two clamping jaws are slidably mounted on the horizontal slide rail and are also connected to the drive end of the clamping cylinder. The rotary lifting drive cylinder is mounted on the side of the mounting plate opposite to the horizontal slide rail.

[0007] Both clamping jaws have clamping notches, which together abut against the sleeve body. The mounting plate has a first guide hole and a lifting through hole. The sleeve mounting assembly includes a placement seat, a sleeve body, and a positioning post. The placement seat has a second guide hole and an installation channel. The guide rod passes through the first guide hole and the second guide hole in sequence. The installation channel includes a sleeve mounting hole and an axial through hole that are connected in sequence. The axial through hole is connected to the lifting through hole. The sleeve body is located in the sleeve mounting hole. The positioning post passes through the lifting through hole, the axial through hole, and the sleeve mounting hole in sequence so that the positioning post abuts against the sleeve body. The positioning post is connected to the drive shaft of the rotary lifting drive cylinder. The placement seat is fixedly connected to the mounting plate.

[0008] In one embodiment, the sleeve disassembly and assembly tool further includes a buffer pad located inside the lifting through hole. The two ends of the buffer pad abut against the placement seat and the drive shaft of the rotary lifting drive cylinder, respectively. The buffer pad is also slidably sleeved on the positioning post.

[0009] In one embodiment, the cushioning pad is a silicone pad.

[0010] In one embodiment, the sleeve mounting assembly further includes a height sensor group, which includes a first height sensor and a second height sensor, wherein the first height sensor is disposed on the placement base and the second height sensor is disposed on the mounting plate.

[0011] In one embodiment, the sensing end of the first height sensor is positioned opposite to the sensing end of the second height sensor.

[0012] In one embodiment, the two clamping jaws are symmetrically arranged, and the two clamping jaws are respectively connected to the symmetrical drive ends of the clamping cylinder.

[0013] In one embodiment, each of the clamping jaws includes a jaw body, a connecting block, and a sliding seat. The connecting block is connected to the drive end of the clamping cylinder. The jaw body is fixedly connected to the connecting block and the sliding seat respectively. The sliding seat is slidably disposed on the horizontal slide rail. The clamping bodies of the two clamping members are used to jointly clamp the sleeve body.

[0014] In one embodiment, the clamping notch is provided on the gripper body.

[0015] In one embodiment, the diameter of the sleeve mounting hole is larger than the diameter of the axial through hole.

[0016] A sleeve replacement device includes the sleeve disassembly and assembly tool described in any of the above embodiments.

[0017] Compared with the prior art, this disclosure has at least the following advantages:

[0018] The aforementioned sleeve removal and assembly tool eliminates the step of manually removing the sleeve. When it is necessary to remove the sleeve body, the rotary lifting drive cylinder operates, causing the positioning pin to rise under the action of the rotary lifting drive cylinder. Since the positioning pin abuts against the sleeve body, the sleeve body rises accordingly to detach from the sleeve mounting hole. Subsequently, two clamping jaws clamp the sleeve body to complete the sleeve removal. In addition, the sleeve removal and assembly tool of this solution uses multiple sleeve removal and assembly mechanisms, which can save the time of removing the sleeve and thus improve the overall efficiency of sleeve removal and assembly.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] Please see Figures 1 to 3 The present invention relates to a sleeve disassembly and assembly tool 1, which includes multiple sleeve disassembly and assembly mechanisms 10. Each sleeve disassembly and assembly mechanism 10 includes a clamping device 100, a rotary lifting drive cylinder 200, a sleeve mounting assembly 300, a guide rod 400, and a mounting plate 500. The clamping device 100 includes a horizontal slide rail 110, a clamping cylinder 120, and two clamping claws 130. The clamping cylinder 120 and the horizontal slide rail 110 are both mounted on the mounting plate 500. The two clamping claws 130 are slidably mounted on the horizontal slide rail 110 and are also connected to the drive end of the clamping cylinder 120. Specifically, the clamping cylinder 120 has two drive ends, and these drive ends can extend and retract towards or away from each other. The rotary lifting drive cylinder 200 is mounted on the side of the mounting plate 500 away from the horizontal slide rail 110.

[0030] like Figure 2As shown, both clamping jaws 130 have clamping notches 130a, which are used to jointly abut against the sleeve body 320. The mounting plate 500 has a first guide hole 501 and a lifting through hole 502. The sleeve mounting assembly 300 includes a placement seat 310, a sleeve body 320, and a positioning post 330. The placement seat 310 has a second guide hole 311 and an installation channel. The guide rod 400 passes through the first guide hole 501 and the second guide hole 311 in sequence for installation. The channel includes a sleeve mounting hole 312 and an axial through hole 313 connected in sequence. The axial through hole 313 is connected to the lifting through hole 502. The sleeve body 320 is located in the sleeve mounting hole 312. The positioning pin 330 is sequentially inserted through the lifting through hole 502, the axial through hole 313 and the sleeve mounting hole 312 so that the positioning pin 330 abuts against the sleeve body 320. The positioning pin 330 is connected to the drive shaft of the rotary lifting drive cylinder 200. The placement seat 310 is fixedly connected to the mounting plate 500.

[0031] The aforementioned sleeve removal and assembly tool eliminates the manual removal step of the sleeve. When it is necessary to remove the sleeve body, the rotary lifting drive cylinder operates, causing the positioning pin to rise under the action of the rotary lifting drive cylinder. As the positioning pin abuts against the sleeve body, the sleeve body rises accordingly to detach from the sleeve mounting hole. Subsequently, two clamping jaws clamp the sleeve body to complete the sleeve removal. In addition, this sleeve removal and assembly tool adopts multiple sleeve removal and assembly mechanisms, which can save the time of removing the sleeve and thus improve the overall efficiency of sleeve removal and assembly. When the rotary lifting drive cylinder 200 operates, it drives the sleeve body 320 to rise by rotation, which can reduce the difficulty of removing the sleeve body 320.

[0032] like Figure 2 As shown, in one embodiment, the sleeve disassembly and assembly tool 1 further includes a buffer pad 600, which is located within the lifting through hole 502. The two ends of the buffer pad 600 abut against the placement seat 310 and the drive shaft of the rotary lifting drive cylinder 200, respectively. The buffer pad 600 is also slidably fitted onto the positioning post 330. Thus, the buffer pad 600 reduces wear between the placement seat 310 and the drive shaft of the rotary lifting drive cylinder 200, ensuring smooth operation of the rotary lifting drive cylinder 200. When the drive shaft of the rotary lifting drive cylinder 200 rises to a certain height, the buffer pad 600 abuts against the placement seat 310. Further, the buffer pad 600 is a silicone pad.

[0033] like Figure 3As shown, in one embodiment, the sleeve mounting assembly 300 further includes a height sensor group 340, which includes a first height sensor 341 and a second height sensor 342. The first height sensor 341 is disposed on the placement seat 310, and the second height sensor 342 is disposed on the mounting plate 500. When the rotary lifting drive cylinder 200 moves the placement seat 310, its first height sensor 341 also moves up and down accordingly. Thus, the distance between the first height sensor 341 and the second height sensor 342 is displayed as a digital signal on the corresponding control panel, i.e., the current height, so that the operator can view it in real time. Further, the sensing end of the first height sensor 341 and the sensing end of the second height sensor 342 are arranged opposite to each other. The first height sensor 341 and the second height sensor 342 are used to jointly measure the distance between the side position of the placement seat 310 and the mounting plate 500.

[0034] In one embodiment, two clamping jaws 130 are symmetrically arranged, and the two clamping jaws 130 are respectively connected to the symmetrical drive ends of the clamping cylinder 120. That is, the clamping cylinder 120 has two symmetrical drive ends, and each clamping jaw 130 is connected to a corresponding drive end.

[0035] In another embodiment, the drive end of the clamping cylinder 120 is a telescopic shaft, that is, it has a telescopic function.

[0036] like Figure 4 As shown, in one embodiment, each clamping jaw 130 includes a jaw body 131, a connecting block 132, and a sliding seat 133. The connecting block 132 is connected to the drive end of the clamping cylinder 120. The jaw body 131 is fixedly connected to the connecting block 132 and the sliding seat 133 respectively. The sliding seat 133 is slidably disposed on the horizontal slide rail 110. The clamping bodies of the two clamping members are used to jointly clamp the sleeve body 320. It can be understood that when the clamping cylinder 120 is working, it will drive the connecting block 132 to move. In turn, the connecting block 132 will drive the jaw body 131 to move. Since the sliding seat 133 is slidably disposed on the horizontal slide rail 110 and is connected to the jaw body 131, the jaw body 131 moves on the horizontal slide rail 110, thereby causing the two jaw bodies 131 to clamp the sleeve body 320 or release the clamping of the sleeve body 320. Furthermore, a clamping notch 130a is provided on the gripper body 131 so that both gripper bodies 131 act on the sleeve body 320.

[0037] like Figure 2 As shown, in one embodiment, the diameter of the sleeve mounting hole 312 is larger than the diameter of the axial through hole 313, so that after the sleeve body 320 is installed, it rests against the bottom of the sleeve mounting hole 312 and will not go any further.

[0038] This disclosure also provides a sleeve replacement device, including the sleeve removal and installation tool 1 of any of the above embodiments.

[0039] Compared with the prior art, this disclosure has at least the following advantages:

[0040] The aforementioned sleeve removal and assembly tool eliminates the step of manually removing the sleeve. When it is necessary to remove the sleeve body, the rotary lifting drive cylinder operates, causing the positioning pin to rise under the action of the rotary lifting drive cylinder. Since the positioning pin abuts against the sleeve body, the sleeve body rises accordingly to detach from the sleeve mounting hole. Subsequently, two clamping jaws clamp the sleeve body to complete the sleeve removal. In addition, the sleeve removal and assembly tool of this solution uses multiple sleeve removal and assembly mechanisms, which can save the time of removing the sleeve and thus improve the overall efficiency of sleeve removal and assembly.

[0041] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
