Description

Technical Field

[0001] This invention relates to the field of automotive parts production and conveying technology, specifically to an automated suspension conveying device for automotive brake caliper production. Background Technology

[0002] Automotive brake calipers are key load-bearing components of automotive braking systems. Their production requires multiple processes, and the workpiece needs to be frequently transferred between various workstations. They are irregular in shape, have thick walls in some areas, are heavy, and have high requirements for surface quality.

[0003] Existing production lines mostly use ground roller conveyors or flat chain conveyors for transferring workpieces. However, this method has several shortcomings when applied to brake caliper production: the calipers are irregular in shape, making them unstable when placed flat during transport. They are also prone to bumps and scratches during transport, affecting processing accuracy and surface corrosion resistance. Furthermore, some processes require multi-angle and all-around workpiece handling, which cannot be achieved by flipping the workpieces when placed flat. This often requires manual loading, unloading, and flipping, resulting in high labor intensity, long production cycles, and low efficiency.

[0004] Therefore, it is necessary to design a suspended conveying device that can be transported in three dimensions, stably clamped, automatically positioned by lifting, rotating and flipping, and has the ability to coordinate and control multiple workstations, taking into account the production characteristics of automotive brake calipers. Summary of the Invention

[0005] The purpose of this invention is to provide an automated suspension conveying device for the production of automotive brake calipers, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automated suspended conveying device for automobile brake caliper production, comprising a frame base, wherein a horizontally closed annular suspended conveying track is supported and fixed on the frame base by multiple support columns; a drive reduction motor is installed at one end of the frame base; a conveying chain is arranged in the inner cavity of the suspended conveying track; the drive reduction motor is connected to the conveying chain and drives the conveying chain to circulate along the suspended conveying track; a tensioning device for adjusting the tension of the conveying chain is provided at the other end of the suspended conveying track; the suspended conveying track... A circular bottom rail is provided on one side, and multiple sliding trolleys are arranged at intervals along the circular bottom rail in the direction of operation. Each sliding trolley is equipped with a roller assembly that rolls in conjunction with the suspended conveyor rail. The roller assembly includes a load-bearing wheel to bear the vertical load and a guide wheel to limit lateral swing. A suspension rod is vertically connected to the lower end of each sliding trolley, and a lifting drive electric cylinder is connected to the lower end of the suspension rod. The piston rod of the lifting drive electric cylinder is connected downward to a lifting sleeve. Two lifting guide rods are symmetrically arranged on the left and right sides of the lifting drive electric cylinder, and the lower ends of the lifting guide rods are fixedly connected to the lifting sleeve. A rotating mechanism is connected to the lower part of the lifting sleeve.

[0007] According to the above technical solution, the rotating mechanism includes a rotary reduction motor and a slewing bearing, and the lower end of the slewing bearing is connected to a clamping mechanism housing.

[0008] According to the above technical solution, a clamping cylinder is vertically installed inside the housing of the clamping mechanism. The piston rod of the clamping cylinder is connected downward to the main clamping block. Auxiliary clamping blocks are respectively provided on the left and right sides of the main clamping block. The top of the auxiliary clamping blocks is connected to the telescopic rod structure. The clamping cylinder drives the main clamping block to extend into the gap of the brake caliper. The telescopic rod structure drives the auxiliary clamping blocks to laterally and outward to tighten the inner wall of the brake caliper gap, forming an internal support clamping.

[0009] According to the above technical solution, the sliding trolley can be temporarily connected or disconnected from the conveyor chain via a slide groove on one side of the annular bottom rail. In the connected state, the conveyor chain drives the sliding trolley to automatically transport along the suspended conveyor track in an annular manner. In the disconnected state, the sliding trolley can slide independently along the annular bottom rail, forming a dual working mode.

[0010] According to the above technical solution, the two lifting guide rods move vertically in sync with the lifting sleeve. Under normal working conditions, they maintain vertical extension and contraction in the same direction to constrain radial offset and circumferential deflection. When there is slight assembly gap stress, workpiece clamping position deviation or conveying vibration, the lifting guide rods can perform adaptive extension and contraction compensation to offset the slight structural stress and position deviation in real time, avoiding rigid guide jamming and stiffness.

[0011] According to the above technical solution, the rotary reduction motor is fixedly installed at the lower part of the lifting sleeve, and the pinion on its output shaft meshes with the outer gear ring of the slewing bearing for transmission.

[0012] According to the above technical solution, the clamping mechanism adopts a step-by-step cooperative clamping method: the clamping cylinder first drives the main clamping block to descend vertically and extend into the central gap of the brake caliper to complete the initial positioning and main load-bearing; then the telescopic rod structures on both sides start synchronously, pushing the left and right auxiliary clamping blocks to extend outward in the horizontal direction and tighten the inner walls on both sides of the brake caliper gap; when releasing the workpiece, the auxiliary clamping blocks retract first, and the main clamping block then moves upward and exits.

[0013] According to the above technical solution, the telescopic rod structure drives the auxiliary clamping block to perform lateral opening and closing movements, and the clamping stroke is adjustable, which can adapt to the clamping of brake caliper workpieces of different specifications and different gap widths.

[0014] According to the above technical solution, the frame base is an integral rectangular frame welded from carbon structural steel rectangular tubes and I-beams. The frame is reinforced with ribs welded around its perimeter and has adjustable anchor bolts at the bottom. The supporting columns are made of seamless steel pipes, and there are horizontal connecting rods and diagonal tie rods between the columns to form a spatial truss system.

[0015] According to the above technical solution, the suspended conveyor track is made of ordinary I-beams cold-bent by a CNC pipe bending machine, with the ends fully welded together to form a closed loop, and the annular rotating section is a large-radius arc transition; the conveyor chain is a heavy-duty conveyor curved plate chain.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention, by setting up a suspended conveyor track and adopting an aerial suspended circular continuous conveying method, sets up the workpiece logistics line in the upper space of the workshop, completely freeing up the ground operation area. The logistics channel is three-dimensionally separated from the pedestrian and forklift channels, making the site cleaner and more orderly, and significantly improving safety. It is especially suitable for production workshops with limited space. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-2 The present invention provides a technical solution: an automated suspended conveying device for the production of automotive brake calipers, mainly composed of a frame base 1 and a suspended conveying track 2, etc. The whole device adopts an aerial suspended layout, which erects the workpiece conveying line on the workshop floor, making full use of the upper space of the factory building, freeing up the ground operation area, and realizing the three-dimensional separation of logistics and personnel flow.

[0020] The frame base 1 is an integral rectangular frame structure welded from carbon structural steel rectangular tubes and I-beams. The frame is reinforced with stiffening plates around its perimeter to improve overall rigidity and torsional resistance. Adjustable anchor bolts are provided at the bottom for fine-tuning of the level during installation. The frame base 1 serves as the supporting foundation for the entire device, bearing the weight and dynamic loads of all tracks, chains, trolleys, and workpieces.

[0021] The upper part of the frame base 1 is supported and fixed with a horizontally closed ring suspended conveyor track 2 by multiple vertical support columns 17. The support columns 17 are made of seamless steel pipes, and the upper and lower ends are welded to the web of the track and the base frame, respectively. Horizontal connecting rods and diagonal tie rods are provided between the columns to form a stable spatial truss system. In this embodiment, the suspended conveyor track 2 is made of ordinary I-beams, which are cold-bent by a CNC pipe bending machine. After full welding and butt welding at the joint, it is ground flat. The end to end are connected to form a closed loop track. The straight section of the track ensures smooth conveying, and the circular turning section adopts a large radius arc transition to avoid impact and vibration of the sliding trolley at the turning point.

[0022] A conveyor chain 5 is arranged in the inner cavity of the suspended conveyor track 2. In this embodiment, a heavy-duty conveyor curved plate chain is selected. A drive reduction motor 3 is installed at one end of the frame base 1. The drive reduction motor 3 adopts an integrated structure of gear reduction motor, with large output torque and smooth operation. It is connected to the conveyor chain 5 for transmission, driving the conveyor chain 5 to circulate along the suspended conveyor track 2. A tensioning device is provided at the other end of the suspended conveyor track 2. The tensioning device is used to adjust and maintain the reasonable tension of the conveyor chain 5 to prevent the chain from being too loose and causing it to derail, or too tight and causing it to wear out, so as to ensure long-term stable and reliable operation.

[0023] A circular bottom rail 4 is installed on one side of the suspended conveyor track 2. Multiple sliding trolleys 6 are connected at equal intervals along the running direction of the circular bottom rail 4. The sliding trolleys 6 can be connected to the conveyor chain 5 via a chute on one side of the circular bottom rail 4 for the required time period. This connection is manual. The spacing between adjacent sliding trolleys 6 is determined based on the workstation spacing and production cycle. Each sliding trolley 6 is equipped with a roller assembly that rolls in conjunction with the suspended conveyor track 2, including load-bearing wheels 7 that bear vertical loads and guide wheels 8 that limit the lateral sway of the trolley. The load-bearing wheels 7 are solid steel wheels supported by deep groove ball bearings, pressing against the upper flange of the I-beam rail and bearing the entire weight of the suspended workpiece. The combination of the load-bearing wheels 7 and the guide wheels 8 allows the sliding trolleys 6 to move smoothly under the traction of the conveyor chain 5, whether on a straight section or... The circular rotary section can slide smoothly along the suspended conveyor track 2, effectively reducing the swaying and wobbling of the workpiece during the conveying process. The conveyor chain 5 can not only drive the directly fixed track matching structure to achieve closed-loop circular operation, but also drive the manually temporarily assembled sliding trolley 6 and clamping conveying structure to operate synchronously. At the same time, it can rely on its own power to realize the automated circular conveying of the sliding trolley 6 along the suspended conveyor track 2. After being driven by the chain, the sliding trolley 6 can independently rely on the circular bottom rail 4 to complete the sliding operation, realizing a dual working mode. The working mode can be flexibly switched according to the actual production rhythm and workstation operation requirements. It can meet the needs of automated conveying of large batches and continuous workpieces, and can also be adapted to small batches, sampling, and phased manual assisted conveying operations, making the equipment's working condition adaptability wider.

[0024] Each sliding trolley 6 has a suspension rod 9 vertically fixed to its lower end via a pin. The suspension rod 9 is made of solid round steel or thick-walled steel pipe and runs along the track with the sliding trolley 6 to realize the aerial transport and transfer of workpieces between each workstation. The lower end of the suspension rod 9 is equipped with a flange connecting plate for reliable connection with the lifting mechanism below.

[0025] A lifting drive electric cylinder 10 is fixedly connected to the lower flange of the suspension rod 9. The lifting drive electric cylinder 10 is a servo electric cylinder or a stepper electric cylinder. The upper end of the cylinder body is fixedly connected to the flange of the suspension rod 9. Its piston rod extends downward and is connected to the lifting sleeve 11. A rotating mechanism 12 is set below the lifting sleeve 11. In order to ensure the smoothness and guiding accuracy of the lifting movement and prevent torsion and sway during the lifting process, two cylindrical lifting guide rods 25 are symmetrically arranged on the left and right sides of the lifting drive electric cylinder 10. When the lifting drive electric cylinder 10 is activated, the piston rod drives the lifting sleeve 11 and the rotating mechanism 12 below it to rise or fall as a whole. The two lifting guide rods 25 provide reliable linear motion guidance, effectively preventing swaying and twisting during the lifting process, ensuring that the workpiece always maintains a horizontal posture during the lifting process, so as to adapt to the processing height requirements of different workstations, and complete the precise unloading and lifting reset of the workpiece at the workstation. The lifting stroke can be precisely set and adjusted according to the actual process requirements of each workstation through the displacement sensor built into the electric cylinder. When the device performs workpiece lifting operations, the lifting drive electric cylinder 10 starts and drives the piston rod to extend and retract vertically, driving the lifting sleeve 11 to complete the lifting displacement action. The two symmetrically arranged lifting guide rods 25 move vertically synchronously with the lifting sleeve 11. Under normal lifting conditions, the lifting guide rods 25 rely on the upper linear bearing for precise positioning, maintaining vertical extension and retraction in the same direction, strictly constraining the radial offset and circumferential deflection of the lifting sleeve 11 and the lower workpiece structure, ensuring the coaxiality and stability of the overall lifting movement. When a small amount of assembly gap stress, a small positional deviation of the workpiece clamping, or a slight vibration during the conveying operation occurs during the device operation, the two lifting guide rods 25 can rely on adaptive extension and retraction compensation. This flexible operation state can offset the small structural stress and positional deviation in real time, avoiding the jamming, stiffness, structural wear, and workpiece posture deviation problems that are prone to occur in rigid guide structures. Throughout the entire operating cycle, the lifting guide rods 25 always move vertically as the main movement, supplemented by a small amount of adaptive extension and retraction movement, ensuring the continuity and accuracy of lifting and positioning operations at each station.

[0026] The rotating mechanism 12 includes a rotary gear motor 28 and a slewing bearing 27. The rotary gear motor 28 is a flange-mounted gear reducer motor, which is fixedly installed on the lower part of the lifting sleeve 11. Its output shaft extends downward and is equipped with a pinion. The pinion meshes with the outer gear ring of the slewing bearing 27 for transmission. The slewing bearing 27 is bolted to fix the clamping mechanism housing 31.

[0027] When the rotary gear motor 28 is activated, the pinion on the output shaft drives the outer ring of the slewing bearing 27 to rotate, which in turn drives the clamping mechanism housing 31 and the brake caliper 14 it clamps to rotate continuously around the vertical axis at any angle within the range of 0° to 360°. By controlling the number of pulses of the rotary gear motor 28 through the PLC controller, the workpiece can be rotated at a fixed angle or continuously at a uniform speed. This allows for multi-angle and all-round treatment of the workpiece's outer surface in processes such as spraying, cleaning, and visual inspection, completely eliminating the need for manual flipping and significantly reducing the labor intensity of workers. The slewing bearing 27 itself has a strong load-bearing capacity and high rotational accuracy, and can simultaneously withstand large radial loads, axial loads, and overturning moments, ensuring the stability and coaxiality of the workpiece during high-speed rotation.

[0028] A clamping mechanism is connected below the rotating mechanism 12. The clamping mechanism includes a clamping mechanism housing 31, a clamping cylinder 29, and a telescopic rod structure 30.

[0029] The clamping mechanism housing 31 is a box-shaped housing made of aluminum alloy or cast aluminum. Its upper end is connected to the outer ring of the slewing bearing 27. An internal mounting cavity is provided. The clamping cylinder 29 is vertically installed in the center of the clamping mechanism housing 31. The piston rod of the clamping cylinder 29 extends downwards and is threadedly connected to the main clamping block 35. Secondary clamping blocks 13 are provided on both sides of the main clamping block 35. The tops of the secondary clamping blocks 13 are connected to the telescopic rod structures 30 in their respective directions. Driving the clamping cylinder 29 causes the main clamping block 35 to move, thereby... The main clamping block 35 extends into the gap of the brake caliper 14, driving the telescopic rod structure 30 to move and drive the auxiliary clamping block 13 to move, and then extending the auxiliary clamping block 13 into the gap of the brake caliper 14; the internal support clamping structure of the main clamping block and the auxiliary clamping blocks on both sides is adopted to clamp the brake caliper from the internal gap, avoiding the squeezing and scratching of the outer surface of the caliper by external clamping. It is especially suitable for the transfer of workpieces that have completed processes such as spraying and finishing with high requirements for the quality of the outer surface, effectively protecting the integrity of the workpiece's appearance and the machined surface; When the device reaches the loading station and needs to clamp the brake caliper 14, the piston rod of the clamping cylinder 29 extends downward, driving the main clamping block 35 to descend vertically. This causes the main clamping block 35 to first insert into the central gap of the brake caliper 14, completing initial positioning and main support. Subsequently, the main clamping block 35... The telescopic rod structures 30 on both sides are activated simultaneously, pushing the two auxiliary clamping blocks 13 on the left and right to extend outward in the horizontal direction, so that the outer support surface of the auxiliary clamping blocks 13 abuts against and tightens the inner walls on both sides of the gap of the brake caliper 14. The reliable clamping of the brake caliper 14 is achieved through the internal support tensioning action. When it is necessary to release the workpiece, the telescopic rod structure 30 retracts first, driving the auxiliary clamping blocks 13 on both sides to retract inward and disengage from the inner wall of the caliper gap; then the piston rod of the clamping cylinder 29 retracts upward, driving the main clamping block 35 to move upward as a whole, completely withdrawing from the gap of the brake caliper 14, completing the unloading action. In the entire clamping and releasing process, the main clamping block 35 is responsible for vertical insertion positioning and main load bearing, while the auxiliary clamping blocks 13 on both sides are responsible for horizontal internal support clamping. The two work together to achieve stable support and positioning of the brake caliper 14 from the inside out. The step-by-step collaborative clamping method, in which the main clamping block is inserted for positioning and the secondary clamping block is laterally tightened, provides clear positioning reference and high clamping repeatability. The main clamping block bears the main vertical load and provides radial reference, while the secondary clamping block provides lateral tension and restricts circumferential rotation. The two work together to achieve precise centering and reliable anti-rotation of the workpiece. The telescopic rod structure drives the secondary clamping block to open and close laterally, and the clamping stroke is adjustable. It can adapt to clamping brake caliper workpieces of different specifications and gap widths within a certain range. It has strong versatility and is easy to adjust quickly when changing products on the production line without having to replace the entire clamping jaw. The internal support clamping completely exposes the outer surface of the workpiece without any jaw obstruction, facilitating all-round, dead-angle-free processing of the workpiece's outer surface during processes such as spraying, inspection, and deburring. No additional flipping or avoidance actions are required, simplifying the process and improving processing efficiency and quality consistency.
