Description

Technical Field

[0001] This utility model belongs to the field of automotive parts assembly technology, and relates to a feeding mechanism, particularly a feeding mechanism for automotive parts assembly. Background Technology

[0002] In the process of assembling automotive parts, the assembly of the automotive chassis is inseparable from the cooperation of the parts. During the installation of the parts, due to their large weight, corresponding lifting equipment is often used for assistance.

[0003] A search revealed a Chinese patent document disclosing a lifting device for assembling automotive parts [Application No.: 202321908430.4; Publication No.: CN 220578779 U]. This lifting device for assembling automotive parts includes: a horizontal plate, a slider slidably mounted on the horizontal plate, a drive mechanism for horizontally adjusting the slider, a hook fixedly connected to the bottom center of the slider, and a clamping mechanism below the hook for limiting the position of the lifted parts. U-shaped support plates are vertically mounted on both sides of the horizontal plate. The advantages are: the drive mechanism facilitates horizontal adjustment of the lifted parts according to assembly needs, improving the practicality of the lifting operation; the clamping mechanism facilitates clamping the lifted parts, preventing swaying during lifting and ensuring stability.

[0004] Although the patent makes it easier to clamp the lifting accessories by setting up a clamping mechanism to prevent them from shaking during the lifting process and affecting the stability of the lifting, the hook lifting does have its drawbacks. For example, if the hook lacks a hook guard or the hook guard fails, the heavy object, lifting rope or special lifting tool can easily fall out of the hook opening, causing the heavy object to fall. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a feeding mechanism for assembling automotive parts. The technical problem to be solved by this utility model is: how to adjust the tightness of the lifting rope to bind and fix the workpiece, and to clamp and fix one end of the lifting rope to prevent the lifting rope from slipping or breaking free.

[0006] The objective of this utility model can be achieved through the following technical solutions: A feeding mechanism for assembling automotive parts includes a gantry frame and a mounting frame slidably connected to the gantry frame. Two lifting frames are slidably connected to the mounting frame, each lifting frame is equipped with a lifting component, and a pair of universal wheels are rotatably connected to the bottom of both the left and right sides of the gantry frame. Fixing components are provided at the bottom of both the left and right sides of the gantry frame, and drive screws are rotatably connected to both the left and right sides of the gantry frame. Each drive screw is threadedly connected to the mounting frame, and a servo motor is fixed to both the left and right sides of the gantry frame. The output shaft of each servo motor is coaxially fixedly connected to the corresponding drive screw.

[0007] The working principle of this utility model is as follows: the car parts can be hoisted and fixed by the hoisting assembly, and then the entire gantry can be moved by the outward wheels to realize the feeding action, thereby improving the overall assembly feeding efficiency. Then, the drive motor drives the drive screw to rotate, and the drive screw drives the mounting frame to adjust the height, so that the car parts are lifted off the ground and the hoisting work can be carried out normally, improving the loading efficiency and the safety of parts feeding.

[0008] The hoisting assembly includes through holes in each hoisting frame and a pair of adjusting gears rotatably connected in each hoisting frame. Parts of the teeth of each pair of adjusting gears mesh with each other in the corresponding through holes. Each pair of adjusting gears is coaxially fixedly connected with a meshing gear. The meshing gears are tightly meshed with each other. Each hoisting frame is fixedly equipped with a second servo motor. The output shaft of each second servo motor is coaxially fixedly connected to one of the adjusting gears. Each hoisting frame is fixedly equipped with a hoisting rope at its bottom. One end of each hoisting rope is clamped and engaged with the corresponding pair of adjusting gears.

[0009] Using the above structure, one of the adjusting gears can be rotated by the servo motor, which in turn drives the corresponding meshing gear to rotate. The rotation of one meshing gear will drive the other meshing gear to rotate, causing both adjusting gears to rotate. At this time, one end of the lifting rope is inserted into the hole, and the tightening degree of the lifting rope is adjusted by the meshing and rotating motion of the two adjusting gears, thereby binding and fixing the workpiece.

[0010] The fixing assembly includes a fixing frame fixed to the bottom of both sides of the gantry frame, a stabilizing cylinder slidably connected to the bottom of both sides of the gantry frame, a pair of stabilizing rods fixed to the bottom of both sides of the gantry frame, a limit plate fixedly connected to the bottom end of each pair of stabilizing rods, a corresponding limit plate fixedly connected to the bottom end of each stabilizing cylinder, a drive screw rotatably connected to each fixing frame, a threaded connection between the bottom of each drive screw and the corresponding stabilizing cylinder, and a servo motor three fixed inside each fixing frame, with the output shaft of each servo motor three coaxially fixedly connected to the corresponding drive screw.

[0011] With the above structure, the servo motor can drive the screw to rotate, and the drive screw can move the stabilizing cylinder, thereby pressing the push limit plate down to contact the ground, thus limiting the overall movement of this application and achieving the effect of stabilizing and limiting.

[0012] Each of the perforations is slidably connected to a fixing ring, and each fixing ring is fitted with one end of a corresponding hoisting rope. Each hoisting frame is fixed with an electric telescopic rod, and the telescopic end of each electric telescopic rod is fixedly connected to the corresponding fixing ring.

[0013] With the above structure, the fixed ring can be moved by the electric telescopic rod to clamp and fix one end of the hoisting rope, thereby preventing the hoisting rope from slipping or breaking free.

[0014] The mounting frame is rotatably connected to a bidirectional lead screw, and the threaded section of each bidirectional lead screw is threadedly connected to the corresponding lifting frame. A servo motor four is fixed inside the mounting frame, and the output shaft of the servo motor four is coaxially fixedly connected to the bidirectional lead screw.

[0015] With the above structure, a servo motor can drive a two-way lead screw to rotate. After the two-way lead screw rotates, it will drive the two lifting frames to move in opposite directions or in opposite directions, thereby realizing corresponding adjustments according to the size of the lifting workpiece and further improving the lifting stability.

[0016] Compared with existing technologies, this feeding mechanism for assembling automotive parts has the following advantages: 1. The car parts are hoisted and fixed by the hoisting components, and then the entire gantry is moved by the outward wheels to realize the feeding action and improve the overall assembly feeding efficiency.

[0017] 2. The tightening of the hoisting rope is adjusted by the meshing and rotating motion of two adjusting gears, thereby binding and fixing the workpiece.

[0018] 3. It enables corresponding adjustments based on the size of the workpiece being hoisted, further improving the hoisting stability. Attached Figure Description

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-5 As shown, a feeding mechanism for assembling automotive parts includes a gantry frame 1 and a mounting frame 2 slidably connected to the gantry frame 1. Two lifting frames 3 are slidably connected to the mounting frame 2. Each lifting frame 3 is equipped with a lifting component. A pair of universal wheels 4 are rotatably connected to the bottom of the left and right sides of the gantry frame 1. Fixing components are provided at the bottom of the left and right sides of the gantry frame 1. Drive screws 5 are rotatably connected to the left and right sides of the gantry frame 1. Each drive screw 5 is threadedly connected to the mounting frame 2. Servo motors 6 are fixed to the left and right sides of the gantry frame 1. The output shaft of each servo motor 6 is coaxially fixedly connected to the corresponding drive screw 5.

[0027] Automotive parts can be hoisted and fixed using a hoisting assembly. Then, the entire gantry frame 1 is moved by the outward wheels to achieve the feeding action, thereby improving the overall assembly feeding efficiency. The drive motor 1 drives the drive screw 5 to rotate, and the drive screw 5 drives the mounting frame 2 to adjust its height, so that the automotive parts can be lifted off the ground and the hoisting work can be carried out normally, improving the loading efficiency and the safety of parts feeding.

[0028] The hoisting assembly includes through holes 7 in each hoisting frame 3, and a pair of adjusting gears 8 rotatably connected in each hoisting frame 3. Parts of the teeth of each pair of adjusting gears 8 mesh with each other in the corresponding through holes 7. Each pair of adjusting gears 8 is coaxially fixedly connected with a meshing gear 9. The meshing gears are tightly meshed. Each hoisting frame 3 is fixedly equipped with a servo motor 2 10. The output shaft of each servo motor 2 10 is coaxially fixedly connected to one of the adjusting gears 8. Each hoisting frame 3 is fixedly equipped with a hoisting rope 11 at the bottom. One end of each hoisting rope 11 is clamped and engaged with the corresponding pair of adjusting gears 8.

[0029] Using the above structure, one of the adjusting gears 8 can be rotated by the servo motor 10. One of the adjusting gears 8 drives the corresponding meshing gear 9 to rotate. The rotation of one meshing gear 9 will drive the other meshing gear 9 to rotate, so that the two adjusting gears 8 rotate. At this time, one end of the lifting rope 11 is inserted into the through hole 7. The tightening degree of the lifting rope 11 is adjusted by the meshing and rotation of the two adjusting gears 8, thereby binding and fixing the workpiece.

[0030] The fixing components include fixing frames 12 fixed to the bottom of both sides of the gantry frame 1, stabilizing cylinders 13 slidably connected to the bottom of both sides of the gantry frame 1, a pair of stabilizing rods 14 fixed to the bottom of both sides of the gantry frame 1, a limit plate 15 fixedly connected to the bottom end of each pair of stabilizing rods 14, and a corresponding limit plate 15 fixedly connected to the bottom end of each stabilizing cylinder 13. A drive screw 16 is rotatably connected to each fixing frame 12, and the bottom of each drive screw 16 is threadedly connected to the corresponding stabilizing cylinder 13. A servo motor 17 is fixed inside each fixing frame 12, and the output shaft of each servo motor 17 is coaxially fixedly connected to the corresponding drive screw 16.

[0031] With the above structure, the drive screw 16 can be rotated by the servo motor 17, and the drive screw 16 can drive the stabilizing cylinder 13 to move, so that the push limit plate 15 is pressed down to contact the ground, thereby limiting the overall movement ability of this application and achieving the effect of stabilization and limiting.

[0032] Each perforation 7 is slidably connected to a fixing ring 18, and each fixing ring 18 is fitted with one end of a corresponding hoisting rope 11. Each hoisting frame 3 is fixed with an electric telescopic rod 19, and the telescopic end of each electric telescopic rod 19 is fixedly connected to the corresponding fixing ring 18.

[0033] With the above structure, the fixed ring 18 can be moved by the electric telescopic rod 19 to clamp and fix one end of the hoisting rope 11, thereby preventing the hoisting rope 11 from slipping or breaking free.

[0034] The mounting bracket 2 is rotatably connected to a bidirectional lead screw 20. The threaded section of each bidirectional lead screw 20 is threadedly connected to the corresponding lifting bracket 3. The mounting bracket 2 is fixed with a servo motor 4 21. The output shaft of the servo motor 4 21 is coaxially fixedly connected to the bidirectional lead screw 20.

[0035] With the above structure, the servo motor 21 can drive the bidirectional lead screw 20 to rotate. After the bidirectional lead screw 20 rotates, it will drive the two lifting frames 3 to move in opposite directions or in opposite directions, thereby realizing corresponding adjustments according to the size of the lifting workpiece and further improving the lifting stability.

[0036] The working principle of this utility model is as follows: A servo motor 21 drives a bidirectional lead screw 20 to rotate. The rotation of the bidirectional lead screw 20 causes the two lifting frames 3 to move in opposite directions, thus allowing for adjustments based on the size of the workpiece. The lifting rope 11 is then passed through the workpiece, with one end inserted into the through hole 7. A servo motor 10 drives one of the adjusting gears 8 to rotate. This adjusting gear 8 drives the corresponding meshing gear 9 to rotate, and the rotation of one meshing gear 9 drives the other meshing gear 9 to move in the opposite direction. The rotation causes the two adjusting gears 8 to rotate, and the tightening of the lifting rope 11 is adjusted through the meshing rotation of the two adjusting gears 8, thereby binding and fixing the workpiece. The electric telescopic rod 19 drives the fixing ring 18 to move, thereby clamping and fixing one end of the lifting rope 11 to prevent the lifting rope 11 from slipping or breaking free. Then, the drive motor drives the drive screw 5 to rotate, and the drive screw 5 drives the mounting frame 2 to adjust the height, so that the car parts can be lifted off the ground and the lifting work can be carried out normally, improving the loading efficiency and the safety of parts feeding.

[0037] In summary, the car parts are hoisted and fixed by the hoisting assembly, and then the entire gantry 1 is moved by the outward wheels to realize the feeding action, thereby improving the overall assembly feeding efficiency. Then, the drive motor drives the drive screw 5 to rotate, and the drive screw 5 drives the mounting frame 2 to adjust the height, so that the car parts are lifted off the ground and the hoisting work can be carried out normally, improving the loading efficiency and the safety of parts feeding.
