Description

Technical Field

[0001] This invention relates to the field of engineering machinery manufacturing technology, and in particular to a turntable assembly installation device. Background Technology

[0002] The turntable assemblies of construction machinery such as truck cranes, pump trucks, and excavators are heavy, varied, and irregularly shaped. When installing the turntable onto the chassis, the slewing bearing needs to be bolted to the turntable. During connection, the bolts must be aligned with and tightened one by one with the mounting holes on the slewing bearing and the turntable. However, due to the turntable's own structure, the positions of all mounting holes cannot be displayed; most mounting holes are obscured by the turntable's base plate, with only 2 to 9 holes exposed. The mounting holes can only be exposed by rotating the crane to install the bolts. Currently, this installation requires two people: one operates the crane at an angle to rotate the turntable, while the other uses a pneumatic wrench to pre-tighten the bolts and then a torque wrench to finally tighten them. However, this installation method has at least the following disadvantages:

[0003] 1. The overhead crane is angled, which does not comply with the crane's operating specifications. The turntable assembly is heavy, causing significant wear and tear on the crane and affecting its service life. 2. The crane is not a precise positioning device, and the rotation angle of the turntable driven by the crane is difficult to control. 3. Manual installation requires two people to cooperate, posing a safety risk. 4. The wind wrench is heavy, resulting in high labor intensity for workers. 5. The torque wrench is too short, requiring workers to bend over to operate it, which is not ergonomic. 6. There are approximately 36-76 mounting holes, but only about 2-9 can be exposed at the same time, making the current installation method inefficient. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0057] The terms “first,” “second,” “third,” etc., are used merely to distinguish numerical values ​​or elements with similar properties, rather than to indicate or imply relative importance or a specific order.

[0058] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0059] This invention provides a turntable assembly installation device, please refer to... Figures 1 to 4 One embodiment of the turntable assembly mounting device includes a traveling assembly 11, a rotating assembly 13, a traveling bracket 15, a lifting mechanism 17, a clamping mechanism 19, a mounting bracket 21, and a tightening mechanism 23. The traveling assembly 11 includes components that can travel along a first direction (e.g., Figure 1 (in the X direction) and the second direction (e.g.) Figure 2 The trolley 110 moves in the Y direction (as in the first direction), with the second direction perpendicular to the first direction. The rotating component 13 can rotate around a third direction perpendicular to the first and second directions (e.g., the Y direction). Figure 1 The traveling bracket 15 is rotatably connected to the traveling trolley 110 in the Z direction. The traveling support 15 is movably connected to the rotating assembly 13 in a first direction. A lifting mechanism 17 is connected to the traveling support 15, and a clamping mechanism 19 is connected to the lifting mechanism 17. The lifting mechanism 17 is used to drive the clamping mechanism 19 in a third direction (e.g., in the Z direction). Figure 1 The rotating assembly moves in the Z direction. The mounting bracket 21 is fixedly connected to the rotating component 13, and the tightening mechanism 23 is connected to the mounting bracket 21. The tightening mechanism 23 is used to tighten the bolts and other fasteners of the turntable assembly.

[0060] The turntable assembly installation equipment in this embodiment uses a clamping mechanism to hold the turntable in place, and then a rotating component drives it to rotate, gradually exposing the bolts. During this rotation, a tightening mechanism tightens the exposed bolts to a set torque. Throughout the installation process, there is no need for manual operation of the overhead crane to pull the turntable, no need for manual handling of the pneumatic wrench, and no need for manual bending to operate the torque wrench. This ensures that the vehicle being installed on the turntable is free from the risk of tipping over, eliminating the risk of improper use and wear and tear on the crane. Furthermore, the installation requires no multiple personnel, reducing worker fatigue and improving safety. The turntable's rotation angle is highly controllable, effectively improving installation efficiency. Simultaneously, the lifting mechanism only drives the clamping mechanism in a localized lifting motion, resulting in high stability.

[0061] In this embodiment, the traveling assembly 11 includes a crossbeam 111 extending along a first direction. A frame 112 spanning across the two crossbeams 111 is mounted on the crossbeam 111. The frame 112 is movably mounted on the crossbeam 111 along the first direction, and the traveling trolley 110 is movably mounted on the frame 112 along a second direction. Specifically, the traveling assembly 11 may also include columns 113, with both ends of the crossbeam 111 connected to the two columns 113 respectively. The columns 113 and the crossbeam 111 are fixedly mounted. It is understood that the columns 113 may also be omitted, and a track can be set on the factory wall, serving as the crossbeam 111. The two ends of the frame 112 are movably mounted on the track. Through the traveling assembly 11, the rotating assembly 13 can be driven to adjust its position in the first and second directions, so that the clamping mechanism 19 and the tightening mechanism 23 are roughly aligned with the workpiece (i.e., the turntable), and the needs of different types of workpieces can be met. The traveling trolley 110 includes a rotary mating part 1101. The traveling crane assembly 11 also includes a first driving component for driving the crossbeam 111 and the traveling trolley 110 to move. Specifically, the first driving component may be a motor. Specifically, the slewing mating part 1101 may include a flange connected to the rotating assembly 13, enabling a rigid connection between the traveling crane assembly 11 and the rotating assembly 13, ensuring smooth operation of the rotating assembly 13 and its connected components, and preventing inertial rotation or swaying of the traveling crane assembly 11 during lifting. Specifically, the traveling crane assembly 11 may be a programmable traveling crane, and its wheels may be self-locking to ensure stability during the robot's tightening motion.

[0062] Specifically, a first track clamp (not shown) is provided on the frame 112 for clamping or releasing the crossbeam 111, and a second track clamp (not shown) is provided on the trolley assembly 11 for clamping or releasing the frame 112. When the frame 112 moves into position on the crossbeam 111, the first track clamp locks its position; when the trolley assembly 11 moves into position on the frame 112, the second track clamp locks its position. This prevents the equipment from shifting after stopping due to the movement of components such as the lifting mechanism 17 and the tightening mechanism 23 caused by large inertia, thereby improving the stability of the entire equipment during operation.

[0063] Specifically, the traveling component 11 is equipped with a barcode device to detect the position of the turntable, thereby controlling the traveling trolley 110 to reach the appropriate position and achieve positioning with high accuracy.

[0064] In this embodiment, please refer to Figures 5 to 8 The rotating assembly 13 includes a rotating body 131, a second driving member 133, and a rotating part 135 (see...). Figure 11The second driving member 133 is used to drive the rotating part 135 to rotate relative to the rotating mating part 1101 of the traveling assembly 11. The rotating part 135 is fixedly connected to the rotating body 131, and the rotating part 135 and the rotating mating part 1101 are rotatably mated together.

[0065] Specifically, please refer to Figures 9 to 12 The rotating part 135 includes a transmission part 1351 and a sleeve part 1353 connected to the transmission part 1351. The rotating assembly 13 also includes a brake 138, which is used to brake or release the sleeve part 1353, thereby braking or releasing the rotating assembly 13. When the rotating assembly 13 rotates to its position, the brake 138 brakes the rotating part 135, preventing the rotating assembly 13 from rotating arbitrarily. This prevents equipment shaking due to large component inertia, thus ensuring the control accuracy of the equipment. When the rotating assembly 13 needs to rotate, the brake 138 releases the sleeve part 1353. Specifically, the sleeve part 1353 is rotatably fitted inside the rotating fitting part 1101. This large-area fitting method can improve the stability of the connection between the rotating assembly 13 and the traveling assembly 11. Specifically, the rotating body 131 is also provided with a brake bracket 142, and the brake 138 is mounted on the brake bracket 142. Specifically, the rotating assembly 13 also includes a transmission member 136, which is driveably connected between the second driving member 133 and the transmission part 1351 of the rotating part 135. Specifically, both the transmission member 136 and the transmission part 1351 of the rotating part 135 are gears that mesh with each other. The transmission member 136 is located on the output shaft of the second driving member 133. The second driving member 133 can be a motor. The motor drives the transmission member 136 to rotate, thereby causing the rotating part 135 to rotate relative to the rotating mating part 1101, thus causing the rotating body 131 to rotate together. It is understood that the second driving member 133 and the transmission part 1351 of the rotating part 135 can also be driven by other transmission methods.

[0066] Specifically, the rotating assembly 13 further includes a first protective hook 137, which is fixedly connected to the rotating body 131 and hooked onto the rotary engagement portion 1101 of the traveling assembly 11. This prevents the rotating assembly 13 from falling off when the rotary part 135 disengages from the rotary engagement portion 1101. Specifically, the rotating assembly 13 also includes a slip ring 139, which is fixedly connected to the rotating body 131 and makes electrical contact with a contact element (not shown) on the traveling assembly 11. The contact element may be annular, and the slip ring 139 contacts the peripheral wall of the contact element. During the rotation of the rotating assembly 13, the slip ring 139 remains in electrical contact with the contact element, thereby providing power to the rotating assembly 13 to meet the power requirements of components such as the first drive element and the second drive element 133.

[0067] Specifically, the rotating assembly 13 also includes an angle detection element, which is used to detect the rotation angle of the rotating assembly 13.

[0068] Specifically, the rotating assembly 13 further includes a second protective hook 141. The rotating body 131 is provided with a first slide rail 1311, and the second protective hook 141 is movably disposed on the first slide rail 1311 along a first direction. Specifically, the first slide rail 1311 may be two parallel and spaced apart.

[0069] In this embodiment, please refer to Figures 13 to 16 The traveling support 15 includes a traveling body 151 and a third drive component 153. The third drive component 153 drives the traveling body 151 to move relative to the rotating body 131 along a first direction. Specifically, the third drive component 153 can be a motor. The traveling support 15 can move along the first direction, which can meet the installation requirements of different types of turntables.

[0070] Specifically, the walking bracket 15 also includes a drive rod 155, and a slider 156 is provided on the walking body 151. The drive rod 155 is connected to the output shaft of the third drive member 153, and the drive rod 155 and the slider 156 are connected by a screw and nut mechanism. When the third drive member 153 is working, it drives the drive rod 155 to rotate, thereby causing the slider 156 to move along the length of the drive rod 155, and thus driving the walking body 151 to move linearly. It can be understood that the third drive member 153 and the walking body 151 can also be transmitted through other transmission methods such as gears and racks.

[0071] Specifically, the walking bracket 15 also includes a third protective hook 158, which is fixedly connected to the second protective hook 141. This prevents the walking bracket 15 from falling when the drive rod 155 disengages from the slider 156.

[0072] In this embodiment, please refer to Figures 17 to 20 The lifting mechanism 17 includes a lifting body 171, a slide 173, and a fourth driving member 175. The lifting body 171 has a lifting track 1711 extending in a third direction. The slide 173 is movably mounted along the lifting track 1711. The fourth driving member 175 drives the slide 173 to move relative to the lifting body 171 along the lifting track 1711. The lifting body 171 is fixedly connected to the traveling body 151 of the traveling support 15. The lifting mechanism 17 can lift the turntable according to its height. When the turntable rotates to a certain angle, it may tip over due to instability. The lifting mechanism can hold the turntable up to absorb lateral pressure and prevent tipping.

[0073] Specifically, the lifting mechanism 17 also includes a chain bracket 177, a rotary wheel 178, and a chain 179. The chain 179 is wound around the rotary wheel 178, and a slide block 173 is connected to the chain 179. A fourth driving member 175 drives the rotary wheel 178 to rotate, thereby moving the chain 179 and causing the slide block 173 to rise and fall along the lifting track 1711. It is understood that the fourth driving member 175 and the slide block 173 can also be driven by other transmission methods such as gears and racks. The chain lifting mechanism ensures stability during lifting and thus improves equipment accuracy. Specifically, the chain 179 can be a sleeve roller chain. Specifically, two rotary wheels 178 are wound around the same chain 179. One rotary wheel 178 is mounted on the chain bracket 177 as a drive wheel connected to the fourth driving member 175 to drive the chain 179 to move, and the other rotary wheel 178 is a movable pulley structure. The lifting load of the lifting mechanism 17 can be doubled by the movable pulley structure to meet the needs of large loads and to keep the turntable in place even when the center of gravity is unstable.

[0074] Specifically, the lifting body 171 is equipped with a fixed rack (not shown), and the slide 173 is equipped with a movable locking tooth (not shown). The movable locking tooth is movably configured to engage with or disengage from one of the fixed teeth of the fixed rack. When the lifting mechanism 17 is in position, the movable locking tooth can be controlled to engage with one of the fixed teeth of the fixed rack to prevent the slide 173 from falling abnormally in the event of equipment malfunction (e.g., sudden chain breakage), thus ensuring safety and stability. In other words, the fixed rack and the movable locking tooth together form a safety fall arrestor. Specifically, the movable locking tooth can move under the action of an electromagnet.

[0075] In this embodiment, please refer to Figures 21 to 23 The clamping mechanism 19 includes a clamping body 191, clamping arms 193, and a fifth driving member 195. The clamping body 191 is connected to the slide 173 of the lifting mechanism 17. The two clamping arms 193 are connected to the clamping body 191, and the two clamping arms 193 can move relative to each other to move closer or further apart.

It can be understood that the fifth driving member 195 and the clamping arm 193 can also be connected through other transmission structures such as gears and racks. By setting the belt structure 197, the fifth driving member 195 and the lead screw can be arranged parallel to each other, thereby reducing the width of the equipment.

[0077] Specifically, each of the two clamping arms 193 is equipped with a clamping pin 1931, which are positioned opposite each other. The clamping pins 1931 are used to insert into the arm pin holes of the turntable, thereby clamping the turntable. Of course, the clamping pins 1931 can also be omitted, and the clamping arms 193 can directly clamp the outer side walls of the turntable. Specifically, the clamping pins 1931 can be stepped shafts to accommodate arm pin holes of different sizes.

[0078] Specifically, the clamping mechanism 19 also includes a first vision system (not shown), which is used to obtain the position of the arm pin hole of the turntable, so as to accurately insert the clamping pin 1931 into the arm pin hole and ensure accurate clamping positioning.

[0079] In this embodiment, please refer to Figures 24 to 27 The mounting bracket 21 includes a mounting body 211 and a base frame 213. The mounting body 211 is fixedly connected to the rotating body 131 of the rotating assembly 13, and the base frame 213 is fixedly connected to the bottom of the mounting body 211. Specifically, the mounting bracket 21 also includes a diagonal brace 215. One end of the diagonal brace 215 is connected to the mounting body 211, and the other end is fixedly connected to the rotating body 131 of the rotating assembly 13. The diagonal brace 215 is inclined. By setting the diagonal brace 215, the connection strength between the mounting bracket 21 and the rotating assembly 13 can be enhanced.

[0080] Specifically, the main body 211 is provided with a control box bracket 2111 at one end near the base frame 213. An electrical control cabinet 217 is installed on the control box bracket 2111. The electrical control cabinet 217 is connected to the tightening mechanism 23 to control the action of the tightening mechanism 23.

[0081] Specifically, the mounting bracket 21 also includes a second vision system 218, which is used to acquire the position of the turntable and ensure that the rotation center of the turntable is consistent with the rotation center of the rotating assembly 13. Specifically, the second vision system 218 is located on the rotation center line of the rotating assembly 13.

[0082] In this embodiment, the tightening mechanism 23 includes a robot 231 and a gripper assembly 233. The robot 231 is mounted on the base frame 213 of the mounting bracket 21, and the gripper assembly 233 is mounted on the end of the robot 231 so that the robot 231 can drive the adjustment of the position and tighten the bolts. The tightening mechanism 23 uses the robot 231 to control the movement of the gripper assembly 233. While performing the corresponding actions, the robot 231 can also act as a counterweight to maintain the balance of the components below the rotating assembly 13 without the need for additional counterweights.

[0083] Specifically, robot 231 includes a first arm and a second arm. The first arm is connected to the base frame 213, the second arm is movably connected to the first arm, and a gripper assembly 233 is mounted on the second arm. Robot 231 can move in multiple degrees of freedom.

The tightening gripper 2331 is connected to the robot 231, and the sleeve 2333 is installed on the tightening gripper 2331. The sleeve 2333 is used to fit over a bolt and tighten the bolt by rotation. Specifically, there can be two tightening grippers 2331 and two sleeves 2333. The two sleeves 2333 can tighten two bolts simultaneously, which is a dual-axis torque-controlled method. Compared with single-axis torque-controlled method, dual-axis torque-controlled method can effectively counteract the reaction force brought by the bolt during the tightening process, thus eliminating the need for a reaction arm. It is simple, reliable, and enables rapid installation, improving production efficiency.

[0085] Specifically, the tightening mechanism 23 also includes a marking device 235, which is used to automatically mark the bolt. After the bolt is tightened and marked, if any abnormalities such as loosening occur during subsequent operations, the marking can be used to conveniently and promptly detect them.

[0086] Specifically, the tightening mechanism 23 also includes a third vision system (not shown), which is used to obtain the position of the mounting holes of the turntable assembly in order to tighten the bolts according to the third vision system.

[0087] In this embodiment, the tightening mechanism 23 further includes a sleeve parking station 238, which is used to place sleeves 2333. When the bolts to be tightened are of different types, the sleeves 2333 on the tightening gripper 2331 can be removed, and a suitable sleeve 2333 stored in the sleeve parking station 238 can be installed on the tightening gripper 2331. Specifically, in this embodiment, three sleeve parking stations 238 are provided.

[0088] Specifically, please refer to again Figure 28The sleeve parking station 238 includes a placement bracket 2381 and a clamping part 2382. The placement bracket 2381 is provided with placement positions 2383 for placing sleeves 2333. Each sleeve parking station 238 can be provided with two placement positions 2383 to place sleeves 2333 in pairs, corresponding to two tightening grippers 2331. The clamping part 2382 includes a pressure arm 2385 and a clamping drive member 2386. The pressure arm 2385 is formed with a clamping part, and two spaced-apart pressure plates 2388 form the clamping part. When clamping, the two pressure plates 2388 are respectively located on both sides of the sleeve 2333 to clamp the sleeve 2333. Specifically, each clamping part 2382 is provided with two pressure arms 2385 to correspond to two placement positions 2383. The clamping drive 2386 is connected to the pressure arm 2385 and is used to drive the pressure arm 2385 to clamp or release the sleeve 2333 located in the placement position 2383. The clamping part 2382 can accurately position the sleeve 2333 in a predetermined position so that the tightening gripper 2331 can be accurately aligned with the sleeve 2333 for replacement. Specifically, the clamping drive 2386 can be a cylinder.

[0089] Specifically, please refer to Figure 32 The tightening gripper 2331 includes a connecting portion 2335, and the sleeve 2333 includes a connecting end 2336 and a tightening end 2337. The connecting end 2336 is used to connect or disconnect from the connecting portion 2335 of the tightening gripper 2331, and the tightening end 2337 is used to tighten the bolts that need to be tightened on the turntable. The connecting portion 2335 is provided with a protrusion 2338 that can move in a direction perpendicular to the axis of the sleeve 2333, so that the protrusion 2338 can engage or disengage from the groove of the connecting end 2336, thereby connecting or disengaging the sleeve 2333 to or from the tightening gripper 2331. The connecting portion 2335 also includes a first elastic member 2339 that applies a force toward the axis of the sleeve 2333 to the protrusion 2338, so that the protrusion 2338 automatically engages into the groove when it reaches the position corresponding to the groove. The connecting end 2336 is provided with a tapered surface 2340 to resist the elastic force of the first elastic element 2339 and push the protrusion 2338 away from the axis of the sleeve 2333 during the process of the sleeve 2333 and the tightening gripper 2331 approaching each other. In this embodiment, the tightening gripper 2331 and the sleeve 2333 are mechanically self-locking connected, so that the sleeve 2333 can withstand a large force when tightened without falling off the tightening gripper 2331. The tightening gripper 2331 also includes an adjusting shaft 2342 connected to the protrusion 2338 and a releasing drive connected to the adjusting shaft 2342. The releasing drive drives the adjusting shaft 2342, which in turn drives the protrusion 2328 to move away from the axis of the sleeve 2333, thereby disengaging the sleeve 2333 from the connecting part 2335 of the tightening gripper 2331, so that the sleeve 2333 that needs to be replaced can be removed. Specifically, the releasing drive can be a cylinder.
