Description

Technical Field

[0001] This invention relates to the field of battery tie rod technology for automotive batteries, and more particularly to a battery tie rod assembly device. Background Technology

[0002] Automotive batteries, also known as vehicle assemblies, are installed in the engine compartment at the front of the vehicle to provide power. Chinese utility model patents, such as CN202695581U and CN202669699U, disclose a battery fixing structure and mounting device. The bottom of the battery rests in a tray inside the vehicle compartment, with fixing structures on both sides, such as mounting ears. The top of the battery is held in place by a battery pressure plate, with each end of the pressure plate connected to the mounting ears via a battery pull rod. The lower end of the battery pull rod is hooked to engage with a through hole in the mounting ear, while the upper end of the pull rod passes through a through hole in the pressure plate and is then locked in place by a nut.

[0003] On the automobile production line, before assembling the battery, the battery rods, trays, and battery pressure plates are usually placed separately. However, the corresponding nuts need to be pre-assembled on each battery rod. During subsequent assembly, the nuts only need to be removed and then screwed back on after assembly, so there is no need to store the nuts separately.

[0004] In the existing technology, since the battery rod is an irregularly shaped part, there is no special equipment to complete the assembly of the nut and the battery rod. The nut is tightened on the battery rod manually, which is labor-intensive and has low assembly efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery pull rod assembly device that can achieve automated operation, assembling a nut on one end of the pull rod to form a pull rod nut assembly, which greatly improves assembly efficiency.

[0006] The present invention provides a battery pull rod assembly device, comprising:

[0007] A feeding box for accommodating multiple pull rods, the feeding box having a feeding port at the bottom;

[0008] A rotary operating mechanism includes a turntable with a receiving groove and a turntable drive module for driving the turntable to rotate. The turntable is pivotally mounted below the discharge port, and the receiving groove is used to receive a pull rod falling from the discharge port.

[0009] A movable operating mechanism is assembled around the rotary operating mechanism to drive the pull rod in the receiving groove to move linearly.

[0010] A nut tightening mechanism is assembled at one end of the rotary operating mechanism to assemble a nut onto the end of a pull rod that is linearly conveyed by the movable operating mechanism, thereby forming a pull rod nut assembly.

[0011] A receiving box, mounted below the rotary operating mechanism, is used to receive the pull rod nut assembly falling from the turntable;

[0012] The moving operating mechanism is also used to drive the assembled tie rod nut assembly to reset on the turntable and release the reset tie rod nut assembly.

[0013] The turntable is used to rotate the repositioned tie rod nut assembly so that the tie rod nut assembly falls off the turntable after rotating a preset angle.

[0014] In one alternative technical solution, the battery pull rod assembly equipment further includes a nut conveying mechanism for conveying a nut to the nut tightening mechanism.

[0015] In one of the alternative technical solutions, the rotary operating mechanism includes a pair of spaced-apart turntables, each turntable having a plurality of material receiving grooves evenly distributed along the circumference;

[0016] The moving operation end of the moving operation mechanism is arranged between the two turntables and is used to drive the pull rod that falls into the material receiving groove at the top of the turntable to move linearly.

[0017] In one of the alternative technical solutions, the moving operating mechanism includes two roller assemblies, which are symmetrically arranged on opposite sides of the axis of the turntable;

[0018] The roller assembly includes a mounting frame, a sliding plate slidably connected to the mounting frame, a roller pivotally mounted at the end of the sliding plate and arranged horizontally, a roller drive module for driving the roller to rotate, and a sliding plate drive module for driving the sliding plate to extend and retract.

[0019] When the moving operating mechanism is in the initial state, the sliding plates of both roller assemblies are in the retracted state;

[0020] When the moving operating mechanism is in operation, the sliding plates of both roller assemblies are extended and the rollers are rotating.

[0021] In one of the alternative technical solutions, the nut tightening mechanism includes a fixed frame, a nut tightening sleeve pivotally mounted on the fixed frame, a sleeve moving drive module for driving the nut tightening sleeve to move along the axial direction of the pull rod, and a sleeve rotating drive module for driving the nut tightening sleeve to rotate.

[0022] The fixed frame is provided with a nut receiving channel, and the outlet end of the nut receiving channel is provided with a nut outlet and a sleeve inlet on opposite sides, respectively, with the nut outlet facing the rotating operating mechanism.

[0023] When the nut tightening mechanism is in operation, the nut tightening sleeve can enter the nut receiving channel through the sleeve inlet and can rotate to tighten the nut.

[0024] In one of the alternative technical solutions, a root notch is formed on the side of the nut outlet near the inlet end of the nut receiving channel;

[0025] A baffle is provided on the outside of the root notch, and the baffle has a stop block that can extend into the root notch;

[0026] A baffle driving module is connected between the fixing frame and the baffle. The baffle driving module is used to drive the baffle to move along the axial direction of the nut tightening sleeve, so that the baffle is inserted into or leaves the root notch, so that only one nut enters the nut assembly station at the outlet end at a time.

[0027] In one of the alternative technical solutions, a movable plate is provided on the side of the fixed frame facing the rotating operating mechanism, and a movable plate drive module for driving the movable plate to move is provided between the movable plate and the fixed frame;

[0028] The movable plate has a nut stop arm extending toward the nut outlet, the nut stop arm having a U-shaped opening for the pull rod to pass through.

[0029] In one of the alternative technical solutions, a vibration motor is provided on each side of the discharge port.

[0030] In one of the optional technical solutions, the feeding box includes a fixed feeding box main board, two feeding box side plates connected to both sides of the feeding box main board, a feeding box adjustment plate that is arranged opposite to the feeding box main board and is movable, and an adjustment seat connected to the bottom of the feeding box adjustment plate;

[0031] The material box adjustment plate and the material box main plate are arranged along the length direction of the pull rod;

[0032] The adjusting seat is provided with a translation plate that can move along the length of the pull rod and a locking structure for locking the translation plate. The material box adjusting plate is connected to the translation plate.

[0033] In one of the alternative technical solutions, a guide plate extending toward the receiving box is fixed on one side of the turntable;

[0034] The upper end of the guide plate is located on one side of the axis of the turntable and is used to drive the pull rod that has been rotated into position to disengage from the receiving groove. The guide plate is also used to guide the falling pull rod nut assembly into the receiving box.

[0035] The above technical solution has the following beneficial effects:

[0036] The battery pull rod assembly equipment provided by this invention pre-places the pull rod in the feeding box. When the turntable of the rotating operating mechanism rotates so that the receiving groove is aligned with the feeding port, the pull rod falls from the feeding port and into the receiving groove. Then, the moving operating mechanism drives the threaded end of the pull rod to move toward the nut tightening mechanism. The nut tightening mechanism assembles the nut onto the threaded end of the pull rod to form a pull rod nut assembly. Then, the moving operating mechanism drives the pull rod to move in the opposite direction to reset. After the pull rod resets, the moving operating mechanism pulls the pull rod, and the turntable drives the pull rod nut assembly to rotate. After the turntable rotates a preset angle, the pull rod disengages from the receiving groove, and the pull rod nut assembly falls from the turntable and automatically falls into the receiving box.

[0037] Therefore, the battery pull rod assembly equipment provided by the present invention realizes automated operation, and can automatically assemble the nut on one end of the pull rod to form a pull rod nut assembly, which greatly improves the assembly efficiency. Attached Figure Description

Detailed Implementation

[0066] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0067] like Figure 1-7 , Figure 10-17 and Figure 22-27 As shown, a battery pull rod assembly device provided in one embodiment of the present invention includes:

[0068] The feeding box 1 is used to accommodate multiple pull rods 71, and the bottom of the feeding box 1 has a feeding port 15.

[0069] The rotary operating mechanism 2 includes a turntable 22 with a receiving groove 221 and a turntable drive module 23 for driving the turntable 22 to rotate. The turntable 22 is pivotally mounted below the discharge port 15. The receiving groove 221 is used to receive the pull rod 71 falling from the discharge port 15.

[0070] The movable operating mechanism 3 is assembled around the rotary operating mechanism 2 and is used to drive the pull rod 71 in the receiving groove 221 to move linearly.

[0071] The nut tightening mechanism 4 is assembled at one end of the rotary operating mechanism 2 and is used to assemble the nut 72 to the end of the pull rod 71 that is linearly conveyed by the moving operating mechanism 3 to form the pull rod nut assembly 7.

[0072] The receiving box 5 is mounted below the rotary operating mechanism 2 and is used to receive the pull rod nut assembly 7 falling from the turntable 22.

[0073] The movable operating mechanism 3 is also used to drive the assembled tie rod nut assembly 7 to reset on the turntable 22 and release the reset tie rod nut assembly 7.

[0074] The turntable 22 is used to drive the reset tie rod nut assembly 7 to rotate so that the tie rod nut assembly 7 falls off the turntable 22 after rotating a preset angle.

[0075] The battery pull rod assembly equipment provided by this invention is used for automatically assembling battery pull rods and nuts. In this invention, the battery pull rod is simply referred to as pull rod 71, which, together with nut 72, forms a pull rod and nut assembly 7. One end of the battery pull rod 71 is a hook end 711, used for assembly with the ear plate on the side of the battery tray; the other end of the pull rod 71 is a threaded end 712, used for assembly with nut 72 to achieve assembly with the battery pressure plate.

[0076] The battery pull rod assembly equipment provided by the present invention includes a feeding box 1, a rotating operating mechanism 2, a moving operating mechanism 3, a nut tightening mechanism 4, and a receiving box 5, etc.

[0077] The aforementioned components can be installed on the first worktable 100 or in other designated locations. The first worktable 100 includes a first table surface 101 at the top and a support table surface 102 located below the first table surface 101.

[0078] The battery pull rod assembly equipment provided by the present invention also includes a control device for controlling the automatic operation of each electrical component.

[0079] The feeding box 1 is mounted on the first platform 101 via a support frame. The feeding box 1 is used to accommodate multiple pull rods 71. The bottom of the feeding box 1 has a feeding port 15, which is narrow or elongated, allowing only one pull rod 71 to pass through at a time. In this embodiment, the length direction of the pull rod 71 is defined as the front-to-back direction. The front-to-back length of the feeding box 1 remains unchanged. The bottom of the side plate of the feeding box 1 gradually narrows towards the middle to form a narrow feeding port 15, so that the multiple pull rods 71 ​​piled in the feeding box 1 will automatically move to the feeding port 15, and only one pull rod 71 can automatically fall through the feeding port 15 at a time.

[0080] The rotating operating mechanism 2 is mounted below the feeding box 1 to receive the pull rod 71 falling from the feeding port 15 and to drive the pull rod 71 to rotate, so that the pull rod 71 can be disengaged from the rotating operating mechanism 2.

[0081] Specifically, the rotary operating mechanism 2 includes a bracket 21, a turntable 22, and a turntable drive module 23. The bracket 21 is mounted on the first table 101 and is located below the discharge port 15.

[0082] The turntable 22 is connected to the bracket 21 via a pivot shaft, and the length of the turntable 22 along the axial direction can be set as needed. The circumferential surface of the turntable 22 is provided with at least one receiving groove 221, which extends along the axial direction of the turntable 22 and is used to receive the pull rod 71 falling from the discharge port 15.

[0083] The distance between the pivot of turntable 22 and the discharge port 15 is equal to or slightly greater than the diameter of turntable 22, or the minimum distance between the circumferential surface of turntable 22 and the discharge port 15 is less than the diameter of the rod body of pull rod 71. This arrangement ensures that when turntable 22 rotates, the circumferential surface of turntable 22 can rotate against the discharge port 15, or the gap between them prevents pull rod 71 from entering. When turntable 22 rotates, pull rod 71 cannot fall into the gap between turntable 22 and discharge port 15; only when the receiving groove 221 rotates below the discharge port 15 will pull rod 71 automatically fall into the receiving groove 221.

[0084] The turntable drive module 23 is mounted on the bracket 21 or in another designated location to drive the turntable 22 to rotate. The turntable drive module 23 can be a motor or electric motor and is controlled by a control device.

[0085] During the period from when the pull rod 71 falls into the receiving groove 221 until the nut 72 is installed, the turntable 22 does not rotate, keeping the receiving groove 221 directly above the turntable 22 for operation by the moving operating mechanism 3. The turntable 22 only starts to rotate when it is necessary to lower the assembled pull rod and nut assembly 7, so that the pull rod and nut assembly 7 can disengage from the receiving groove 221 and fall into the receiving box 5.

[0086] The movable operating mechanism 3 is mounted on the first platform 101, surrounding the rotary operating mechanism 2. The movable operating mechanism 3 is used to drive the pull rod 71 in the receiving groove 221 to move linearly. The movable operating mechanism 3 can be a gripper mechanism, a double roller drive mechanism, etc. The drive end or operating end of the movable operating mechanism 3 is used to grasp or release the pull rod 71. This drive end or operating end can move to the area below the discharge port 15, thereby grasping the pull rod 71 that has fallen into the receiving groove 221. When the drive end or operating end drives the pull rod 71 to move linearly, the turntable 22 does not rotate. This drive end or operating end can also retract away from below the discharge port 15, thereby releasing the pull rod 71. Here, "forward or backward" is defined radially along the pull rod 71 in the horizontal direction: when the drive end or operating end moves horizontally toward the pull rod 71, it is called forward movement of the drive end or operating end; when the drive end or operating end moves horizontally away from the pull rod 71, it is called backward movement of the drive end or operating end.

[0087] Specifically, after the pull rod 71 falls into the receiving groove 221, the drive end or operating end moves forward to grasp the pull rod 71 that has fallen into the receiving groove 221, and then drives the pull rod 71 to move towards the nut tightening mechanism 4, so that the threaded end 712 can cooperate with the nut tightening mechanism 4. The nut tightening mechanism 4 then tightens the nut 72 onto the threaded end 712, forming the pull rod and nut assembly 7. This process is called the process of driving the pull rod 71 to move forward and cooperate. Here, "moving forward" means that the pull rod 71 moves towards the side indicated by the threaded end 712.

[0088] Then, the drive end or operating end drives the pull rod 71 to retract and reset, causing the threaded end 712 with the nut 72 to leave the nut tightening mechanism 4. This process is called the pull rod 71 retraction and reset process, where "retraction" means that the pull rod 71 moves toward the side indicated by the hook end 711.

[0089] After the pull rod 71 / pull rod nut assembly 7 is reset on the turntable 22, the drive end or operating end retracts away from below the discharge port 15, releasing the pull rod 71. Then, the turntable 22 can be driven to rotate, causing the pull rod nut assembly 7 to rotate. After rotating a certain angle, the pull rod 71 disengages from the receiving groove 221, and the pull rod nut assembly 7 automatically falls into the receiving box 5.

[0090] The nut tightening mechanism 4 is mounted on the first platform 101, with one end of its rotating operating mechanism 2 facing the threaded end 712 of the pull rod 71 on the rotating operating mechanism 2. The nut tightening mechanism 4 has a nut tightening sleeve 42, which can automatically tighten the nut 72. The nut tightening mechanism 4 is used to assemble the nut 72 onto the threaded end 712 of the pull rod 71, which is linearly conveyed by the moving operating mechanism 3, to form a pull rod nut assembly 7.

[0091] Specifically, when it is necessary to assemble nut 72, the pull rod 71 on the moving turntable 22 of the moving operating mechanism 3 moves toward the nut tightening mechanism 4 until the threaded end 712 can engage with the nut tightening sleeve 42. The nut tightening sleeve 42 rotates to tighten nut 72 onto the threaded end 712. Then, the moving operating mechanism 3 drives the pull rod 71 to move backward and reset, and the threaded end 712 drives nut 72 away from the nut tightening mechanism 4.

[0092] The receiving box 5 is installed below the rotating operating mechanism 2 to receive the pull rod nut assembly 7 falling from the turntable 22. When the turntable 22 rotates, the pull rod nut assembly 7 rotates from directly above the turntable 22. After the turntable 22 rotates a certain angle, generally after the turntable 22 rotates more than 90°, the pull rod 71 tends to leave the receiving groove 221. Before the turntable 22 rotates to 180°, the pull rod 71 will disengage from the receiving groove 221, and the pull rod nut assembly 7 will fall from the turntable 22 and then automatically fall into the receiving box 5 below.

[0093] Specifically, the receiving box 5 can be optionally installed on the support platform 102. The first platform 101 has a platform opening 103 for the falling pull rod nut assembly 7 to pass through and fall into the receiving box 5.

[0094] Preferably, the table opening 103 is located on one side of the turntable 22, the receiving box 5 is installed diagonally below the turntable 22, and the table opening 103 is located above the receiving box 5.

[0095] In summary, the battery pull rod assembly equipment provided by the present invention pre-places the pull rod 71 in the feeding box 1. When the turntable 22 of the rotating operating mechanism 2 rotates so that the receiving groove 221 is aligned with the feeding port 15, the pull rod 71 falls from the feeding port 15 and into the receiving groove 221. Then, the moving operating mechanism 3 drives the threaded end 712 of the pull rod 71 to move toward the nut tightening mechanism 4. The nut tightening mechanism 4 assembles the nut 72 onto the threaded end 712 of the pull rod 71 to form the pull rod nut assembly 7. Then, the moving operating mechanism 3 drives the pull rod 71 to move in the opposite direction to reset. After the pull rod 71 is reset, the moving operating mechanism 3 pulls the pull rod 71, and the turntable 22 drives the pull rod nut assembly 7 to rotate. After the turntable 22 rotates at a preset angle, the pull rod 71 disengages from the receiving groove 221, and the pull rod nut assembly 7 falls from the turntable 22 and automatically falls into the receiving box 5.

[0096] Therefore, the battery pull rod assembly equipment provided by the present invention realizes automated operation, and can automatically assemble the nut 72 onto one end of the pull rod 71 to form the pull rod nut assembly 7, which greatly improves the assembly efficiency.

[0097] In one embodiment, such as Figure 1-3 and Figure 5 As shown, the battery pull rod assembly equipment also includes a nut conveying mechanism 6 for conveying the nut 72 to the nut tightening mechanism 4, thereby realizing the automatic conveying and supply of the nut 72.

[0098] The nut conveying mechanism 6 can be installed on the first table 101. Alternatively, a second workbench 200 can be arranged on one side of the first workbench 100, and the nut tightening mechanism 4 can be installed on the second table 201 of the second workbench 200. The height of the second table 201 can be set lower than that of the first table 101 as needed. The second table 201 can be installed on the support platform 202 of the second workbench 200 by multiple adjusting bolts 203 to adjust the height of the second table 201, so as to facilitate the docking and adaptation of the nut conveying channel 61 of the nut conveying mechanism 6 and the nut receiving channel 45 of the nut tightening mechanism 4.

[0099] The nut conveying mechanism 6 includes a nut vibrating plate 60 and a nut conveying channel 61, which is connected between the nut vibrating plate 60 and the nut receiving channel 45 of the nut tightening mechanism 4.

[0100] Multiple nuts 72 are placed on a nut vibratory plate 60, which is driven by a vibratory motor to vibrate and feed the nuts 72 into the nut conveying channel 61. The nuts 72 in the nut conveying channel 61 enter the receiving nut channel 45 in sequence, and are then tightened by the nut tightening sleeve 42.

[0101] In one embodiment, such as Figure 10-13 and Figure 15-16 As shown, the rotary operating mechanism 2 includes a pair of spaced-apart turntables 22, each turntable 22 having a plurality of material receiving grooves 221 evenly distributed along the circumference.

[0102] The movable operating end of the movable operating mechanism 3 is arranged between the two turntables 22 and is used to drive the pull rod 71, which falls into the material receiving groove 221 at the top of the turntable 22, to move linearly.

[0103] In this embodiment, the rotating operating mechanism 2 uses a pair of turntables 22, which are arranged at intervals along the length of the pull rod 71 to support the front and rear ends of the pull rod 71 respectively.

[0104] Each turntable 22 is provided with multiple receiving grooves 221, preferably three receiving grooves 221. Multiple or three receiving grooves 221 are evenly distributed along the circumference of the turntable 22 to improve the efficiency of receiving the pull rod 71 falling from the discharge port 15. Assuming there are n receiving grooves 221 on the turntable 22, where n = 2 or 3, when a receiving groove 221 is directly below the discharge port 15, the pull rod 71 falls into that groove. Then, when the turntable 22 rotates 360° / n, the pull rod nut assembly 7 in that receiving groove 221 falls down, and the next receiving groove 221 reaches directly below the discharge port 15 to receive the next falling pull rod 71, greatly improving work efficiency.

[0105] In one embodiment, such as Figure 6-7 and Figure 10-16 As shown, the moving operating mechanism 3 includes two roller assemblies 31, which are symmetrically arranged on opposite sides of the axis of the turntable 22.

[0106] The roller assembly 31 includes a mounting bracket 311, a sliding plate 312 slidably connected to the mounting bracket 311, a roller 313 pivotally mounted at the end of the sliding plate 312 and arranged horizontally, a roller drive module 314 for driving the roller 313 to rotate, and a sliding plate drive module 315 for driving the sliding plate 312 to extend and retract.

[0107] When the moving operating mechanism 3 is in the initial state, the sliding plates 312 of both roller assemblies 31 are in the retracted state.

[0108] When the moving operating mechanism 3 is in working state, the sliding plates 312 of both roller assemblies 31 are in the extended state, and the rollers 313 are in the rotating state.

[0109] In this embodiment, the moving operation mechanism 3 adopts a dual roller drive mechanism, which includes a pair of roller assemblies 31. The pair of roller assemblies 31 are arranged symmetrically on the left and right sides of the axis of the turntable 22.

[0110] The roller assembly 31 includes a mounting bracket 311, a sliding plate 312, a roller 313, a roller drive module 314, and a sliding plate drive module 315.

[0111] Mounting bracket 311 is fixedly mounted on the first platform 101. A sliding plate 312 is horizontally arranged and mounted on the mounting bracket 311 via guide rails. One end of the sliding plate 312 faces the turntable 22, and it can reciprocate in a horizontal plane along a direction perpendicular to the axis of the turntable 22, thus moving closer to or away from the turntable 22. A roller 313 is mounted on the end of the sliding plate 312 facing the turntable 22. The axle of the roller 313 is perpendicular to the sliding plate 312, and the roller 313 is horizontally arranged. Preferably, the circumferential surface of the roller 313 has a groove for clamping the pull rod 71. A roller drive module 314 is mounted on top of the sliding plate 312 via a connecting bracket. The roller drive module 314 can be a motor / electric drive mechanism and is connected to the roller 313 via a transmission mechanism to drive the roller 313 to rotate. The roller drive module 314 can drive the roller 313 to rotate in both directions to drive the pull rod 71 to move forward or backward. The sliding plate drive module 315 is connected between the mounting bracket 311 and the sliding plate 312, and is used to drive the sliding plate 312 to extend and retract. The sliding plate drive module 315 can be a pneumatic cylinder or a hydraulic cylinder.

[0112] Both the roller drive module 314 and the sliding plate drive module 315 are controlled by the control device.

[0113] Two rollers 313 are located on opposite sides of the axis of turntable 22. When the two rollers 313 approach each other, they can clamp a part of the pull rod 71, thereby driving the pull rod 71 to move forward or backward.

[0114] When the two rollers 313 are separated, the lever 71 can be released.

[0115] When the moving operating mechanism 3 is in the initial state, the sliding plates 312 of the two roller assemblies 31 are in the retracted state, causing the two rollers 313 to separate from each other.

[0116] When the moving operating mechanism 3 is in working state, the sliding plates 312 of the two roller assemblies 31 are both extended, so that the two rollers 313 approach each other and clamp the pull rod 71. The two rollers 313 are in a rotating state, thereby driving the pull rod 71 to move forward or backward.

[0117] Preferably, the roller 313 is positioned between the two turntables 22, and in the height direction, the bottom surface of the roller 313 is slightly lower than the bottom of the uppermost receiving groove 221 of the turntable 22, and the top surface of the roller 313 is higher than the opening of the uppermost receiving groove 221 of the turntable 22, so as to ensure that the pull rod 71 passing through the receiving groove 221 can be clamped.

[0118] When the roller 313 is driven to rotate in the forward direction, the pull rod 71 is driven to move toward the nut tightening mechanism 4, that is, to move forward; when the roller 313 is driven to rotate in the reverse direction, the pull rod 71 is driven to retract and reset, so that the nut 72 on the threaded end 712 leaves the nut tightening mechanism 4.

[0119] In one embodiment, such as Figure 17-20 As shown, the nut tightening mechanism 4 includes a fixed frame 41, a nut tightening sleeve 42 pivotally mounted on the fixed frame 41, a sleeve moving drive module 43 for driving the nut tightening sleeve 42 to move axially along the pull rod 71, and a sleeve rotating drive module 44 for driving the nut tightening sleeve 42 to rotate.

[0120] The fixed frame 41 is provided with a nut receiving channel 45. On the opposite sides of the outlet end 452 of the nut receiving channel 45, there are nut outlet 453 and sleeve inlet respectively. The nut outlet 453 faces the rotating operating mechanism 2.

[0121] When the nut tightening mechanism 4 is in operation, the nut tightening sleeve 42 can enter the nut receiving channel 45 through the sleeve inlet and can rotate and tighten the nut 72.

[0122] In this embodiment, the nut tightening mechanism 4 includes a fixed frame 41, a nut tightening sleeve 42, a sleeve movement drive module 43, a sleeve rotation drive module 44, and a nut receiving channel 45.

[0123] The mounting bracket 41 is fixedly mounted on the first platform 101. The nut tightening sleeve 42 is arranged along the length of the pull rod 71. The nut tightening sleeve 42 is mounted on the mounting bracket 41 via a pivoting structure (e.g., a bearing). The nut tightening sleeve 42 can rotate relative to the mounting bracket 41. One end of the nut tightening sleeve 42 has an internal hexagonal groove for receiving the nut 72 and for tightening the nut 72.

[0124] The sleeve movement drive module 43 is connected between the fixed frame 41 and the nut tightening sleeve 42. It drives the nut tightening sleeve 42 to move axially, allowing it to enter the nut assembly station at the outlet end 452 of the nut receiving channel 45, thereby inserting a nut 72 into the internal hexagonal recess of the nut tightening sleeve 42. After tightening the nut 72, the sleeve movement drive module 43 drives the nut tightening sleeve 42 away from the nut assembly station to avoid affecting subsequent movements of the nut 72 to the nut assembly station. The sleeve movement drive module 43 can be a hydraulic cylinder or a pneumatic cylinder, controlled by a control device.

[0125] The sleeve rotation drive module 44 can be a motor drive mechanism, which is mounted on the fixed frame 41 and connected to the nut tightening sleeve 42 through a transmission mechanism. It is used to drive the nut tightening sleeve 42 to rotate so as to tighten the nut 72.

[0126] A nut receiving channel 45 is located on the side (rear side) of the fixed frame 41 facing the rotating operating mechanism 2. The inlet end 451 of the nut receiving channel 45 is for the nut 72 to enter and can be connected to the nut conveying channel 61. The outlet end 452 of the nut receiving channel 45 is approximately located in the middle of the fixed frame 41. A nut outlet 453 is provided on the wall facing the pull rod 71 (rear side) of the outlet end 452, and a sleeve inlet (not shown) is provided on the wall facing the nut tightening sleeve 42 (front side). The sleeve inlet is directly opposite the nut outlet 453, and the nut assembly position of the nut 72 is located between the sleeve inlet and the nut outlet 453. The nut outlet 453 is for the threaded end 712 of the pull rod 71 to extend into and move the nut 72 out. The sleeve inlet is for the hexagonal recessed end of the nut tightening sleeve 42 to extend into, so as to receive a nut 72 in the nut assembly position into the hexagonal recess.

[0127] When nut 72 needs to be assembled, a nut 72 reaches the nut assembly station at the outlet end 452 via the nut receiving channel 45. The nut tightening sleeve 42 is driven by the sleeve moving drive module 43 to move towards the outlet end 452. Its hexagonal recessed end enters the nut assembly station at the outlet end 452 through the sleeve inlet and receives a nut 72 at the nut assembly station. A pull rod 71 is driven by the moving operating mechanism 3, and its threaded end 712 extends through the nut outlet 453 into the nut assembly station at the outlet end 452 and abuts against the nut 72 at the nut assembly station. The sleeve rotation drive module 44 drives the nut tightening sleeve 42 to rotate, so that the nut 72 is tightened onto the threaded end 712. At the same time, in order to ensure that the nut 72 is tightened to the root of the external thread of the threaded end 712, the pull rod 71 can be pushed by the moving operating mechanism 3 until the nut 72 is tightened to the root of the external thread. After the nut 72 is tightened to the position, the nut tightening sleeve 42 stops rotating and is driven to reset by the sleeve moving drive module 43. The moving operation mechanism 3 drives the pull rod 71 to reset, and causes the nut 72 on the threaded end 712 to move out of the nut outlet 453 and leave the nut tightening mechanism 4.

[0128] In one embodiment, such as Figure 17-18 and Figure 20-21 As shown, a root notch 454 is formed on the side of the nut outlet 453 near the inlet end 451 of the nut receiving channel 45.

[0129] A baffle 46 is provided on the outside of the root notch 454, and the baffle 46 has a stop 461 that can extend into the root notch 454.

[0130] A baffle drive module 47 is connected between the fixed frame 41 and the baffle 46. The baffle drive module 47 is used to drive the baffle 46 to move axially along the nut tightening sleeve 42 so that the stop block 461 is inserted into or leaves the root notch 454, so that only one nut 72 enters the nut assembly station of the outlet end 452 at a time.

[0131] In this embodiment, in order to ensure that only one nut 72 can reach the nut assembly station at the outlet end 452 at a time, a baffle 46 with a stop block 461 and a baffle drive module 47 for driving the baffle 461 to move back and forth are configured.

[0132] Meanwhile, a root notch 454 is provided on the side of the nut outlet 453 near the inlet end 451 of the nut receiving channel 45, for the stop block 461 to be inserted into the nut receiving channel 45 to block the nut 72. The root notch 454 is located at the connection between the outlet end 452 and the main body of the nut receiving channel 45.

[0133] At the outlet end 452, a detection device 40 is also installed to monitor whether there is a nut 72 at the nut assembly station. The detection device 40 can be a nut positioning detection fiber optic or a limit switch, which is connected to the control device signal.

[0134] The baffle 46 is mounted on the outside of the root notch 454, exposing the nut outlet 453. Under normal conditions, the baffle 461 extends into the root notch 454 to prevent the nut 72 behind the nut assembly station from falling into the nut assembly station. That is, when a nut 72 enters the nut assembly station, the baffle 461 extends into the root notch 454 to prevent subsequent nuts 72 from entering the nut assembly station, ensuring that there is only one nut 72 in the nut assembly station.

[0135] The baffle drive module 47 can be a pneumatic cylinder or a hydraulic cylinder, which is connected between the fixed frame 41 and the baffle 46. It is used to drive the baffle 46 to move axially along the nut tightening sleeve 42, so that the stop block 461 can be inserted into or leave the root notch 454, so that only one nut 72 enters the nut assembly station of the outlet end 452 at a time.

[0136] Specifically, when a nut 72 needs to be supplied, the baffle drive module 47 drives the baffle 46 to move, causing the stop block 461 to move towards the outlet end 452 or the outer side of the nut receiving channel 45 through the root notch 454. Of course, the stop block 461 does not necessarily completely leave the root notch 454, as long as its end does not obstruct the movement of the nut 72 in the nut receiving channel 45 towards the outlet end 452. Then, after a nut 72 falls into the nut assembly station at the outlet end 452, the detection device 40 sends a signal, and the control device controls the baffle drive module 47 to operate. The baffle drive module 47 drives the baffle 46 to reset, and the stop block 461 can be inserted into the nut receiving channel 45 through the root notch 454 to block subsequent nuts 72, ensuring that only one nut 72 enters the nut assembly station at the outlet end 452 at a time.

[0137] In one embodiment, such as Figure 17-18 As shown, a movable plate 48 is provided on the side of the fixed frame 41 facing the rotating operating mechanism 2, and a movable plate drive module 49 for driving the movable plate 48 to move is provided between the movable plate 48 and the fixed frame 41.

[0138] The movable plate 48 has a nut stop arm 481 extending toward the nut outlet 453, and the nut stop arm 481 has a U-shaped opening 482 for the pull rod 71 to pass through.

[0139] In this embodiment, to support the nut 72 and prevent it from falling out of the nut outlet 453, a movable plate 48 is provided on the rear side of the fixing frame 41. This movable plate 48 and the baffle 46 are arranged on opposite sides of the nut outlet 453. The movable plate 48 has a nut stop arm 481, which is located at the bottom of the movable plate 48 and is horizontally arranged, extending horizontally from one side of the nut outlet 453 towards it. The end of the nut stop arm 481 has a U-shaped opening 482. The end of the nut stop arm 481 is used to block the outside of the nut outlet 453 to prevent the nut 72 from falling out. The U-shaped opening 482 allows the pull rod 71 to pass through and engage with the nut 72.

[0140] A movable plate drive module 49 is connected between the movable plate 48 and the fixed frame 41, which is used to drive the movable plate 48 to move radially along the nut tightening sleeve 42 and / or move axially along the nut tightening sleeve 42. The movable plate drive module 49 may be composed of several cylinders or hydraulic cylinders, which are controlled by a control device.

[0141] Before nut 72 reaches the nut assembly station, the movable plate drive module 49 moves the movable plate 48, causing the end of the nut stop arm 481 to block the outside of the nut outlet 453, preventing nut 72 from falling out of the nut outlet 453. The threaded end 712 of the pull rod 71 passes through the U-shaped opening 482 and the nut outlet 453 to reach the nut assembly station to mate with the thread 72. After nut 72 is tightened in place, the movable plate drive module 49 drives the movable plate 48 to reset, and the pull rod 71 moves the nut 72 out of the nut outlet 453.

[0142] In one embodiment, such as Figure 10 As shown, a vibration motor 16 is provided on each side of the discharge port 15. Specifically, a vibration motor 16 is provided on each opposite side of the narrow or elongated discharge port 15, and the vibration is used to promote the pull rod 71 to fall from the discharge port 15. The vibration motor 16 is controlled by a control device.

[0143] In one embodiment, such as Figure 1-3 , Figure 6 and Figure 8-9 As shown, the feeding box 1 includes a fixed feeding box main board 11, two feeding box side plates 12 connected to both sides of the feeding box main board 11, a feeding box adjustment plate 13 that is arranged opposite to the feeding box main board 11 and is movable, and an adjustment seat 14 connected to the bottom of the feeding box adjustment plate 13.

[0144] The material box adjustment plate 13 and the material box main plate 11 are arranged along the length of the pull rod 71.

[0145] The adjusting seat 14 is provided with a translation plate 141 that can move along the length of the pull rod 71 and a locking structure 142 for locking the translation plate 141. The material box adjusting plate 13 is connected to the translation plate 141.

[0146] In this embodiment, the feeding box 1 includes a main feeding box 11, two side feeding box plates 12, and a feeding box adjusting plate 13. The main feeding box 11 and the adjusting plate 13 are arranged at intervals along the length of the pull rod 71, and the two side feeding box plates 12 are connected to the two sides of the main feeding box 11 and extend toward the adjusting plate 13.

[0147] The main board 11 of the material bin and the two side plates 12 of the material bin can be installed on the first table 101 through the support frame.

[0148] To facilitate the lowering of the pull rod 71, the two side plates 12 of the material box adopt the following structure:

[0149] The side plate 12 of the material box includes a main side plate 121, a side plate inclined plate 122, and a lower side plate extension plate 123 connected sequentially from top to bottom. The two main side plate plates 121 are vertically arranged, forming a rectangle with the main side plate 11 and the material box adjusting plate 13. The two side plate inclined plates 122 are inclined downwards and towards the center to guide the pull rod 71 to the lower discharge port 15. The two lower side plate extension plates 123 are vertically arranged, thus forming a narrow or elongated discharge port 15 between the two lower side plate extension plates 123. The aforementioned vibration motor 16 is preferably located on the outside of the lower side plate extension plate 123.

[0150] An adjustment seat 14 is installed on the first platform 101 below the material box adjustment plate 13. The material box adjustment plate 13 is connected to the adjustment seat 14, and the distance between the material box adjustment plate 13 and the material box main plate 11 can be adjusted to accommodate pull rods 71 ​​of different lengths.

[0151] The adjusting seat 14 is provided with a translation plate 141 and a locking structure 142. The translation plate 141 is installed on the adjusting seat 14 via a guide rail 143. The lower end of the material box adjusting plate 13 is fixedly connected to the translation plate 141.

[0152] The locking structure 142 is connected between the translation plate 141 and the adjusting seat 14, and is used to lock the translation plate 141 in place, thereby fixing the material box adjusting plate 13. The locking structure 142 can be a locking pin, a latch, a locking tooth, or other similar structure.

[0153] In one embodiment, such as Figure 9As shown, the locking structure 142 includes a rack 1421, a pin 1422, and a torsion spring 1423. The rack 1421 is mounted on the adjusting seat 14. The pin 1422 is mounted on one end of the translation plate 141 via a pivot. The lower end of the pin 1422 is pointed and can be inserted into the tooth groove of the rack 1421 to achieve locking. The torsion spring 1423 is sleeved on the pivot of the pin 1422 and connected between the adjusting seat 14 and the pin 1422, used to press down the pin 1422. When it is necessary to move the translation plate 141, the pin 1422 is lifted, and the translation plate 141 can be moved. After the translation plate 141 is moved into place, the translation plate 141 is released, and the torsion spring 1423 presses down the pin 1422 to lock the translation plate 141.

[0154] In one embodiment, such as Figure 4 , Figure 7 , Figure 10-12 and Figure 26-27 As shown, a guide plate 24 extending toward the receiving box 5 is fixed on one side of the turntable 22.

[0155] The upper end 241 of the guide plate 24 is located on one side of the axis of the turntable 22 and is used to drive the pull rod 71, which has been rotated into position, to disengage from the receiving groove 221. The guide plate 24 is also used to guide the falling pull rod nut assembly 7 into the receiving box 5.

[0156] In this embodiment, a guide plate 24 is provided on one side of the bracket 21. The upper end 241 of the guide plate 24 is slightly lower than the axis of the turntable 22 and is located on one side of the axis of the turntable 22. The lower end 242 of the guide plate 24 extends into the receiving box 5.

[0157] When the turntable 22 rotates, it drives the uppermost receiving groove 221 to rotate toward the upper end 241 of the guide plate 24. When the pull rod 71 in the receiving groove 221 rotates to the upper end 241 of the guide plate 24, the upper end 241 of the guide plate 24 blocks the pull rod 71, causing it to disengage from the receiving groove 221. The falling pull rod nut assembly 7 falls along the guide plate 24 into the receiving box 5.

[0158] As needed, a table opening 103 is provided on the first table 101, and the guide plate 24 passes through the table opening 103 to guide the movement of the pull rod nut assembly 7.

[0159] To ensure the rod nut assembly 7 falls approximately to the center of the receiving box 5, a downwardly extending guide plate 104 is provided on the bottom surface of the first platform 101. The lower end of the guide plate 104 extends to approximately the center of the receiving box 5. The lower end of the guide plate 24 is a downwardly extending guide ramp towards the guide plate 104, with a slope less than that of the main body of the guide plate 24. The falling rod nut assembly 7 is first guided down by the guide plate 24. When passing the guide ramp of the guide plate 24, the slope of the guide ramp is small, which acts as a deceleration effect. Then, the rod nut assembly 7 falls onto the guide plate 104 and finally falls approximately to the center of the receiving box 5 under the guidance of the guide plate 104.

[0160] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0161] The above are merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
