Description

Technical Field

[0001] This application relates to the field of engine boom assembly technology, and in particular to an automatic engine boom screw tightening machine. Background Technology

[0002] Engine booms are tools specifically designed for the safe and stable lifting of engines. They are widely used in fields such as automotive repair and aircraft manufacturing. The nuts on the engine booms play a crucial role in securing and ensuring safety. Specifically, they provide fastening connections, load transfer and bearing, anti-loosening and vibration resistance, fine-tuning and positioning, and safety protection. The fixing nuts need to be connected to the booms during the boom manufacturing process.

[0003] The engine boom assembly includes a fixing nut, an integrally connected elliptical portion, and a straight threaded portion. In the prior art, during the production process of the engine boom assembly, the fixing nut is usually manually connected to the straight threaded portion. Since the straight threaded portion is relatively long and the fixing nut needs to be turned to the end of the straight threaded portion near the elliptical portion, the manual turning of the fixing nut is time-consuming and labor-intensive, which seriously affects the production efficiency of the engine boom assembly. Summary of the Invention

[0004] In order to improve the production efficiency of engine boom assembly while reducing manual labor intensity and input rate, this application provides an automatic engine boom screw tightening machine.

[0005] The automatic engine boom screw-driving machine provided in this application adopts the following technical solution: An automatic engine boom screw tightening machine, comprising: A workbench, on which a support column is connected; A rod clamping module for fixing the elliptical portion, the rod clamping module is connected to the support column, and the rod clamping module is movable along a first axis; A nut placement rotating disk is rotatably connected to the worktable. The nut placement rotating disk has a through hole, and the rotation axis of the nut placement rotating disk coincides with the first axis. A lifting screw-operated module for raising and lowering the boom clamping module, the lifting screw-operated module being connected to the support column and the boom clamping module; A rotation control module for driving the rotation of the nut placement rotary disk, the rotation control module being connected to the worktable and the nut placement rotary disk.

[0006] By adopting the above technical solution, the fixing nut is first placed in the nut placement rotating disk, and then the lifting rod is fixed by the lifting rod clamping module. At this time, the lifting rod and the fixing nut are in corresponding positions. Then, the lifting screw tightening module drives the lifting rod clamping module to move towards the nut placement rotating disk until the lifting rod abuts against the fixing nut. Then, the rotation control module drives the nut placement rotating disk to rotate. While the nut placement rotating disk rotates, the lifting screw tightening module simultaneously lowers the lifting rod until the fixing nut rotates to the side of the straight thread section near the elliptical section, and the connection of the fixing nut is completed. The designed automatic engine lifting rod screw tightening machine uses the workbench as the mounting base for the support rod and the rotation control module. The lifting rod clamping module can clamp and fix the lifting rod. The nut placement rotating disk and the rotation control module work together to realize the rotation of the fixing nut. The lifting screw tightening module works together to realize the descent of the lifting rod. In turn, the nut placement rotating disk and the rotation control module work together to realize the rapid connection between the fixing nut and the lifting rod, thereby effectively improving the production efficiency of the engine lifting rod assembly while reducing the intensity of manual labor and the input rate.

[0007] In one specific implementation, the boom clamping module includes: The mounting block is slidable relative to the support column along a first axis and is connected to the lifting screw module; An anti-rotation rod is installed, which is connected to the mounting block, and there is an angle between the anti-rotation rod and the first axis. The hanging bracket has an open side and a through hole. When the hanging bracket is inserted into the through anti-rotation rod, the through anti-rotation rod will block the open side.

[0008] By adopting the above technical solution, the hanging bracket is first passed through the elliptical part, and then the hanging bracket is placed on the anti-rotation rod. During the process of the nut placement rotating disk rotating to make the fixing nut threadedly connected to the straight thread part, the hanging bracket and the anti-rotation rod can realize the rotation restriction of the rod itself, thereby realizing the quick connection of the fixing nut under the premise of easy assembly and disassembly.

[0009] In one specific implementation scheme, the through-hole anti-rotation rod is set horizontally or the end of the through-hole anti-rotation rod away from the supporting upright is set inclined upward.

[0010] By adopting the above technical solution, the horizontally installed or inclined upward-facing anti-rotation bar can reduce the possibility of the hanging bracket falling off the anti-rotation bar due to vibration or other reasons.

[0011] In one specific implementation, the mounting block is embedded with a magnet, and the hanging bracket can be magnetically attracted and fixed to the magnet on the mounting block.

[0012] By adopting the above technical solution, the designed mounting block with embedded magnets can further reduce the possibility of the hanging bracket falling off the anti-rotation rod due to vibration or other reasons.

[0013] In one specific implementation, a guide rail protrudes from the support pole, and a protruding block that mates with the guide rail is formed on the mounting block, with the protruding block on the mounting block slidably connected to the guide rail.

[0014] By adopting the above technical solution, the designed support rod with a protruding guide rail can cooperate with the protruding block on the mounting block to realize the sliding guidance of the mounting block, thereby facilitating the smooth connection between the fixing nut and the straight thread part.

[0015] In one specific implementation, the lifting and screwing module includes: The telescopic part is connected to the support column; A sliding part, which slides relative to the support column, and is connected to the movable end of the telescopic part; A fault-tolerant spring, one end of which is connected to the sliding part and the other end of which is connected to the mounting block.

[0016] By adopting the above technical solution, the designed lifting screw-tightening module, through the telescopic part, sliding part, and fault-tolerant spring, can achieve the descent of the boom while avoiding jamming caused by the mismatch between the rotation speed of the rotation control module and the descent speed of the boom.

[0017] In one specific implementation, the rotation control module includes: A drive motor is connected to the worktable, and the axial direction of the output shaft of the drive motor is parallel to the first axis. A transmission component for transmitting power to a nut-positioning rotating disk, the transmission component being connected to the output shaft of the drive motor and the nut-positioning rotating disk.

[0018] By adopting the above technical solution, the designed rotation control module can realize the rotation of the nut placement disc through the drive motor and transmission components.

[0019] In one specific implementation, the transmission component includes: A drive gear, which is coaxially connected to the output shaft of the drive motor; The driven gear ring is connected to the bottom wall of the nut placement rotating disk, and the central axis of the driven gear ring coincides with the first axis. The driven gear ring meshes with the driving gear.

[0020] By adopting the above technical solution, the designed transmission component can transmit the power of the drive motor to the rotating disk where the nut is placed through the cooperation of the drive gear and the driven gear ring, thereby realizing the rotation of the fixed nut.

[0021] In one specific implementation, the nut placement rotary disk includes: The base is rotatably connected to the worktable via a hollow rotating shaft, and the rotation axis of the base coincides with the first axis. The limiting part is connected to the top wall of the base, and a limiting cavity for placing a fixing nut is formed in the limiting part.

[0022] By adopting the above technical solution, the designed nut placement rotating disk can be used as the mounting base for the limiting part and can be connected to the rotation control module. The limiting part can prevent relative rotation between the base and the fixed nut.

[0023] In one specific implementation, the limiting portion includes multiple abutment pieces that slide horizontally relative to the base toward a first axis.

[0024] By adopting the above technical solution, the designed abutment piece that slides horizontally toward the first axis can be adapted to fixing nuts of different specifications and models.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The designed automatic engine boom screw-tightening machine uses a workbench as the mounting base for the support boom and rotation control module. The boom clamping module clamps and fixes the boom, while the rotating nut placement disc, in conjunction with the rotation control module, rotates the fixed nut. The lifting screw-tightening module lowers the boom, and together with the rotating nut placement disc and rotation control module, quickly connects the fixed nut to the boom. This effectively improves the production efficiency of the engine boom assembly while reducing manual labor intensity and input rate.

[0026] The designed automatic engine boom screw tightening machine first passes the mounting bracket through the elliptical part, and then the mounting bracket is placed on the anti-rotation rod. During the process of the nut placement disc rotating to make the fixing nut threaded with the straight thread part, the mounting bracket and the anti-rotation rod can restrict the rotation of the boom itself, thereby achieving quick connection of the fixing nut while facilitating assembly and disassembly.

[0027] The designed automatic engine boom screw tightening machine uses a support column with a protruding guide rail to cooperate with a protruding block on the mounting block to achieve sliding guidance of the mounting block, thereby facilitating the smooth connection between the fixing nut and the straight thread part.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses an automatic engine boom screw tightening machine.

[0036] Reference Figure 1 and Figure 2 An automatic engine boom screw tightening machine includes a worktable 1, a nut placement rotating disk 4, and a rotation control module 6. The nut placement rotating disk 4 is rotatably connected to the worktable 1, and the rotation axis of the nut placement rotating disk 4 is vertically set. A limiting cavity is formed inside the nut placement rotating disk 4 to fix the nut. A through hole is formed on the nut placement rotating disk 4 for the straight threaded part to pass through and extend into. The rotation control module 6 is connected to the worktable 1 and the nut placement rotating disk 4, and is used to realize the lifting and lowering of the boom clamping module 3.

[0037] Reference Figure 1 and Figure 2 Specifically, the rotation control module 6 includes a drive motor 61 and a transmission component 62. The drive motor 61 is bolted to the worktable 1, and the axial direction of the output shaft of the drive motor 61 is parallel to the first axis. The transmission component 62 is connected to the output shaft of the drive motor 61 and to the nut placement rotating disk 4, which is used to transmit the power of the output shaft of the drive motor 61 to the nut placement rotating disk 4.

[0038] Reference Figure 1 and Figure 2 More specifically, the transmission component 62 includes a driving gear 621 and a driven gear ring 622. The driving gear 621 is coaxially connected to the output shaft of the drive motor 61, and the driven gear ring 622 is connected to the nut placement rotating disk 4. The central axis of the driven gear ring 622 coincides with the first axis, and the driven gear ring 622 meshes with the driving gear 621. Through the cooperation of the driving gear 621 and the driven gear ring 622, the power of the drive motor 61 can be transmitted to the nut placement rotating disk 4, thereby realizing the rotation of the fixed nut. In this application, the transmission component 62 can also be a driving wheel and a transmission belt.

[0039] Reference Figure 1 and Figure 2 Furthermore, a support rod 2 is connected to the workbench 1. The support rod 2 is bolted to the workbench 1 and is vertically arranged. A hanging rod clamping module 3 is connected to the support rod 2. The hanging rod clamping module 3 is used to fix the elliptical part and can move along the first axis. The rotation axis of the nut placement rotating disk 4 coincides with the first axis. Furthermore, a lifting screw-tightening module 5 is also included. The lifting screw-tightening module 5 is connected to the support rod 2 and the hanging rod clamping module 3, and is used to realize the lifting and lowering of the hanging rod clamping module 3.

[0040] First, place the fixing nut inside the nut placement rotating disk 4, and then fix the lifting rod through the lifting rod clamping module 3. At this time, the lifting rod and the fixing nut are in corresponding positions. Then, the lifting screw tightening module 5 drives the lifting rod clamping module 3 to move towards the nut placement rotating disk 4 until the lifting rod abuts against the fixing nut. Then, the rotation control module 6 drives the nut placement rotating disk 4 to rotate. At the same time as the nut placement rotating disk 4 rotates, the lifting screw tightening module 5 simultaneously lowers the lifting rod until the fixing nut rotates to the side of the straight thread section close to the elliptical section. The connection of the fixing nut is then completed.

[0041] Reference Figure 3Specifically, the boom clamping module 3 includes a mounting block 31, an anti-rotation rod 32, and a hanging bracket 33. The mounting block 31 can slide relative to the supporting column 2 along the first axis and is connected to the lifting screw module 5. The anti-rotation rod 32 is welded and fixed to the mounting block 31, and there is an angle between the anti-rotation rod 32 and the first axis, that is, the anti-rotation rod 32 is not vertically set. The hanging bracket 33 has an open side and a through hole is formed on the hanging bracket 33. When the hanging bracket 33 passes through the through hole onto the anti-rotation rod 32, the through hole... The anti-rotation rod 32 blocks the open side, and the outer contour dimension of the area with the through hole on the hanging bracket 33 is smaller than the cavity dimension of the elliptical part to facilitate insertion. In this application, the hanging bracket 33 is arranged in a U-shape. First, the hanging bracket 33 is passed through the elliptical part, and then the hanging bracket 33 is inserted onto the through anti-rotation rod 32. During the process of the nut placement rotating disk 4 rotating to make the fixing nut threadedly connected to the straight thread part, the hanging bracket 33 and the through anti-rotation rod 32 can realize the rotation restriction of the hanging rod itself, thereby realizing the quick connection of the fixing nut under the premise of easy assembly and disassembly.

[0042] Reference Figure 3 More specifically, in this application, the anti-rotation rod 32 can be set horizontally, or the end of the anti-rotation rod 32 away from the supporting pole 2 can be set inclined upwards. This embodiment only shows the case where the anti-rotation rod 32 is set horizontally. By setting the anti-rotation rod 32 horizontally or inclined upwards at the end away from the supporting pole 2, the possibility of the hanging bracket 33 falling off the anti-rotation rod 32 due to vibration or other reasons can be reduced.

[0043] Reference Figure 3 Furthermore, the mounting block 31 is embedded with a magnet, and the hanging bracket 33 can be magnetically fixed with the magnet on the mounting block 31. The mounting block 31 with embedded magnets can further reduce the possibility of the hanging bracket 33 falling off the anti-rotation rod 32 due to vibration or other reasons. In addition, the support rod 2 has a protruding guide rail, and the mounting block 31 is integrally connected with a protruding block. The protruding block on the mounting block 31 is slidably connected to the guide rail on the support rod 2. The support rod 2 with the protruding guide rail can cooperate with the protruding block on the mounting block 31 to realize the sliding guidance of the mounting block 31, thereby facilitating the smooth connection between the fixing nut and the straight thread part.

[0044] Reference Figure 4In this application, the nut placement rotary disk 4 can be a closed structure that matches the current model of the fixed nut, that is, the nut placement rotary disk 4 forms a fixed-size limiting cavity, or it can be an adjustable-size limiting cavity to accommodate different specifications of fixed nuts. Specifically, the nut placement rotary disk 4 includes a base 41 and a limiting part 42. The base 41 is rotatably connected to the worktable 1 through a hollow rotating shaft. The straight threaded part can extend into the inner cavity of the hollow rotating shaft through a through hole, and the rotation axis of the base 41 coincides with the first axis. The driven gear ring 622 is coaxially connected to the hollow rotating shaft. The limiting part 42 is connected to the top wall of the base 41, and a limiting cavity for placing the fixed nut is formed in the limiting part 42. The base 41 can serve as the mounting base for the limiting part 42 and realize the connection with the rotation control module 6. The limiting part 42 can prevent relative rotation between the base 41 and the fixed nut.

[0045] Reference Figure 4 The limiting part 42 includes multiple abutment pieces 421. The abutment pieces 421 slide horizontally relative to the base 41 along the first axis. That is, after the multiple abutment pieces 421 slide, they can form limiting cavities of different sizes, thereby realizing the accommodation and position restriction of fixing nuts of different specifications. It should be noted that since the abutment pieces 421 can slide relative to the base 41, the limiting cavity is not a closed cavity. In this application, the movement of the abutment pieces 421 can be realized by rotating the nut, or it can be realized by other structures, such as a control frame with a tapered size gradually connected to the base 41 along the first axis. The movement of the abutment pieces 421 is realized by moving the control frame.

[0046] Reference Figure 5 Specifically, the lifting and screwing module 5 includes a telescopic part 51, a sliding part 52, and a fault-tolerant spring 53. The telescopic part 51 is connected to the support rod 2. In this application, the telescopic part 51 can be a pneumatic telescopic rod, an electric telescopic rod, or a cylinder or hydraulic cylinder, etc. In this embodiment, the telescopic part 51 is set as a pneumatic telescopic rod. The sliding part 52 slides relative to the support rod 2 and is connected to the piston rod of the pneumatic telescopic rod. One end of the fault-tolerant spring 53 is welded to the sliding part 52, and the other end is welded to the mounting block 31. Through the telescopic part 51, the sliding part 52, and the fault-tolerant spring 53, while realizing the descent of the boom, the jamming phenomenon caused by the mismatch between the rotation speed of the rotation control module 6 and the descent speed of the boom can be avoided.

[0047] The implementation principle of an automatic engine boom screw tightening machine according to an embodiment of this application is as follows: First, the fixing nut is placed in the nut placement rotating disk 4, and then the boom is fixed by the boom clamping module 3. Specifically, the hanging bracket 33 is first passed through the elliptical part, and then the hanging bracket 33 is passed through the through anti-rotation rod 32. During the process of the nut placement rotating disk 4 rotating to make the fixing nut threaded with the straight thread part, the hanging bracket 33 and the through anti-rotation rod 32 can realize the rotation restriction of the boom itself, thereby realizing the quick connection of the fixing nut under the premise of easy assembly and disassembly.

[0048] At this point, the boom and the fixing nut are in the corresponding positions. Then, the boom clamping module 3 is moved toward the nut placement rotating disk 4 by the lifting and tightening module 5 until the boom and the fixing nut are in contact. Then, the nut placement rotating disk 4 is driven to rotate by the rotation control module 6. At the same time as the nut placement rotating disk 4 rotates, the lifting and tightening module 5 simultaneously lowers the boom until the fixing nut rotates to the side of the straight thread section near the elliptical section. The connection of the fixing nut is then completed.

[0049] The workbench 1 serves as the mounting base for the support rod 2 and the rotation control module 6. The rod clamping module 3 clamps and fixes the rod. The rotating nut placement disc 4, in conjunction with the rotation control module 6, allows the fixed nut to rotate. The lifting and tightening nut module 5 lowers the rod, which, in turn, works with the nut placement disc 4 and the rotation control module 6 to achieve a quick connection between the fixed nut and the rod. This effectively improves the production efficiency of the engine rod assembly while reducing manual labor intensity and input rate.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
