Description

Technical Field

[0001] This utility model relates to the technical field of gear feeding devices, specifically a driven gear quantitative feeding device. Background Technology

[0002] After the driven gear is formed, it usually needs to be corrected and shaped by a precision forming process to improve its geometric accuracy and assembly fit accuracy, so as to ensure good concentricity, operation balance and low noise level during meshing transmission, thereby improving the stability of the transmission system.

[0003] In current industry production, after the blanks are formed, the driven gears are usually piled up in a material box and then transported as a whole by a forklift to the side of the forming machine. The manuals then take them out one by one from the material box and place them at the forming station.

[0004] Although this feeding method has a simple structure and low equipment cost, it mainly relies on manual operation and is difficult to meet the requirements of modern production for automation and continuous operation.

[0005] Traditional material feeding methods have the following shortcomings: First, manual material handling is inefficient, and the operating rhythm cannot be synchronized with high-speed shaping equipment, which can easily become a bottleneck in the operation of the entire line.

[0006] Secondly, the high-intensity, repetitive manual handling operations increase the labor burden and the risk of work-related injuries. At the same time, there are problems such as bumps and damages caused by improper handling, which affect the yield of finished gears.

[0007] To address the problems of low efficiency, high labor intensity, and high workpiece damage rate associated with existing manual feeding methods, there is an urgent need to propose a driven gear quantitative feeding device that can automatically achieve gear quantitative positioning and feeding. Summary of the Invention

[0008] This utility model addresses the shortcomings of existing technologies by proposing a driven gear quantitative feeding device, the specific technical solution of which is as follows:

[0009] A driven gear quantitative feeding device, characterized in that:

[0010] Includes a frame, a first drive motor, a transmission disk, a rotating shaft, stacking components, and a lifting mechanism;

[0011] The rotating shaft is rotatably connected to the frame, the transmission disk is connected to the upper end of the rotating shaft, the first drive motor is located inside the frame, and the first drive motor is used to drive the rotating shaft to rotate, thereby driving the transmission disk to rotate;

[0012] The frame is provided with a feeding area, and the lifting mechanism is located in the feeding area;

[0013] The stacked components are evenly arranged circumferentially along the drive disk;

[0014] Each of the stacked components includes a chassis, a guide shaft, and a first lifting plate. The lower end of the guide shaft is fixedly connected to the middle of the chassis, and the first lifting plate is mounted on the guide shaft via a sliding sleeve.

[0015] The chassis is provided with a set of first through holes, and the transmission disk is provided with a set of second through holes corresponding to the first through holes;

[0016] When the stacking assembly rotates to the feeding area with the transmission disk, the lifting part of the lifting mechanism passes through the second through hole and the corresponding first through hole in sequence, and pushes the first lifting plate to move upward along the guide axis.

[0017] To better realize this utility model, it can be further made as follows:

[0018] The lifting mechanism includes a base, a top plate, a lead screw, a second lifting plate, a guide rod, and a top rod;

[0019] The upper end of the lead screw is rotatably connected to the top plate, and the lower end is rotatably connected to the base.

[0020] Three guide rods are provided between the top plate and the base. The second lifting plate is slidably installed on the three guide rods and threadedly connected to the lead screw.

[0021] The three top rods are evenly arranged on the upper surface of the second lifting plate.

[0022] Furthermore: a driven pulley is fixedly fitted at the lower end of the lead screw, a driving pulley is provided at the bottom of the base, a second drive motor is used to drive the driving pulley to rotate, and a transmission belt is provided between the driving pulley and the driven pulley.

[0023] Furthermore: the feeding area is equipped with sensors, and a sensing trigger is provided at the position corresponding to each stacked component on the outer periphery edge of the transmission disk;

[0024] When the sensor detects the trigger, it outputs a control signal to stop the drive motor, thereby stopping the transmission disk from rotating and positioning the corresponding stacked components at a preset position in the feeding area.

[0025] Furthermore, the inductive trigger is a bolt, and the sensor is a proximity switch sensor used to detect the position signal of the bolt.

[0026] Furthermore, the frame is provided with omnidirectional conveying balls spaced circumferentially along the outer periphery of the transmission disk to support the lower surface of the transmission disk.

[0027] The beneficial effects of this utility model are as follows:

[0028] First, compared with the traditional feeding method that relies on manual labor to place driven gears one by one into the processing equipment, this utility model sets up a stacking component arranged in a ring and combines it with an automatic rotation and lifting structure to realize batch pre-stacking and automatic fixed-point feeding of driven gears, which greatly reduces the frequency of manual intervention and labor intensity, and reduces the operational risks of manual misplacement, omission, and incorrect placement.

[0029] Second, by evenly arranging multiple stacked components in the circumference of the transmission disk and setting a guide shaft to limit its up and down movement direction, the driven gear to be dressed can be stacked and positioned in each stacked component in a stable state.

[0030] Third, by setting a set of vertically aligned second and first through holes on the transmission plate and chassis respectively, and setting a lifting mechanism below the feeding area, the lifting rod can smoothly pass through the transmission plate and chassis and directly lift the first lifting plate, thereby accurately pushing the lower driven gear to the preset material picking height.

[0031] The lifting mechanism adopts a lifting component design based on lead screw and guide rod. The synchronous pulley is driven by the drive motor to rotate, so as to realize the steady lifting of the second lifting plate. At the same time, three top rods are provided in equal angle distribution to cooperate with the force points of the first lifting plate, which realizes the even lifting of the driven gear, avoids skew and jamming, and improves the lifting stability and service life.

[0032] Sensors are installed in the feeding area, and corresponding sensing triggers are set on the edge of the transmission disk to achieve automatic stopping and precise positioning of the stacked components after they rotate to the predetermined feeding position, thus avoiding manual intervention and positioning errors.

[0033] The frame has multiple universal conveyor balls around its outer perimeter that support the lower surface of the transmission disc, which significantly reduces frictional resistance during rotation and effectively distributes the load of the transmission disc's weight onto the transmission shaft.

[0041] like Figures 1 to 4 As shown:

[0042] A driven gear quantitative feeding device includes a frame 1, a drive motor, a transmission disk 3, a rotating shaft 4, a stacking assembly 5, and a lifting mechanism 6.

[0043] The rotating shaft 4 is arranged vertically, and its lower end is rotatably connected to the middle of the table surface of the frame 1 through a bearing assembly.

[0044] The transmission disk 3 is fixedly connected to the upper end of the rotating shaft 4. The transmission disk 3 has a circular structure and is provided with uniformly distributed mounting holes along the circumference for fixing the stacked assembly 5.

[0045] The first drive motor 2 is installed inside the frame 1, and the output shaft of the first drive motor 2 is connected to the lower end of the rotating shaft 4 through a coupling.

[0046] A feeding area is provided on one side of the frame 1, and a lifting mechanism 6 is installed inside the frame 1, located directly below the feeding area.

[0047] The stacking components 5 are evenly arranged around the transmission disk 3, and each stacking component 5 includes a chassis 7, a guide shaft 8 and a first lifting plate 9.

[0048] The guide shaft 8 is a vertically arranged positioning rod. The lower end of the guide shaft 8 is fixedly connected to the middle of the chassis 7. Multiple driven gears to be processed are sequentially sleeved on the guide shaft 8 and stacked on the first lifting plate 9.

[0049] The first lifting plate 9 is a ring structure with a through hole in the center that slides with the guide shaft 8. The first lifting plate 9 can slide vertically on the guide shaft 8. The outer diameter of the first lifting plate 9 is larger than the outer diameter of the driven gear, so as to stably support the entire stacked workpiece.

[0050] The chassis 7 is provided with a set of first through holes 10, and the transmission disk 3 is provided with a set of second through holes 11 corresponding to the first through holes 10. The first through holes 10 and the second through holes 11 are aligned vertically during assembly. When the stacking assembly 5 rotates to the feeding area with the transmission disk 3, the lifting part of the lifting mechanism 6 pushes the first lifting plate 9 up from below by passing through the second through holes 11 on the transmission disk 3 and the first through holes 10 on the chassis 7.

[0051] The lifting mechanism 6 includes a base 13, a top plate 14, a lead screw 15, a second lifting plate 16, a guide rod 17, and a top rod 18.

[0052] The base 13 is fixedly installed inside the frame 1, and the top plate 14 is connected above the base 13 by three guide rods 17 and kept horizontal.

[0053] The upper end of the lead screw 15 is rotatably connected to the top plate 14 via a thrust bearing assembly, and the lower end is rotatably connected to the base 13 via a cylindrical bearing.

[0054] The second lifting plate 16 is sleeved on the guide rod 17 through three guide holes and is threadedly connected to the lead screw 15 in the middle.

[0055] The lower end of the lead screw 15 is fixedly fitted with a driven pulley 19, and the bottom of the base 13 is equipped with a driving pulley 20 that cooperates with it. A synchronous transmission belt 21 is provided between the two.

[0056] The second drive motor 22 drives the active pulley 20 to rotate, thereby driving the lead screw 15 to rotate, realizing the lifting and lowering of the second lifting plate 16.

[0057] Three push rods 18 are evenly distributed at a 120° angle on the second lifting plate 16. The push rods 18 are the lifting parts of the lifting mechanism 6. The upper end of the push rods 18 pushes into a set position on the lower surface of the first lifting plate 9 to push the first lifting plate 9 upward along the guide shaft 8.

[0058] The feeding area is equipped with a proximity switch sensor 12, which is fixedly installed on the frame 1.

[0059] Near each stacked assembly 5, a sensing trigger is provided on the outer periphery edge of the transmission disk 3. The sensing trigger is fixed to the outer circumference edge of the transmission disk 3 with M6 bolts 23, and each sensing trigger corresponds to a corresponding stacked assembly 5.

[0060] When the transmission disk 3 rotates to the feeding area, the sensing trigger enters the detection area of ​​the proximity switch sensor 12. The sensor outputs an electrical signal, which is received by the control system, causing the drive motor to stop running and the transmission disk 3 to stop rotating, thereby achieving precise positioning of the stacked assembly 5 in the feeding area.

[0061] To improve the operational stability of the transmission disc 3, the frame 1 is provided with multiple universal conveying balls 24 spaced around the lower outer periphery of the transmission disc 3. The balls of the universal conveying balls 24 are in contact with the bottom outer edge of the transmission disc 3, effectively supporting the weight of the transmission disc 3 and reducing rotational friction resistance.

[0062] The principle of this utility model:

[0063] During operation, multiple stacked components 5 are evenly distributed circumferentially along the transmission disk 3 and rotate synchronously around the central axis with the transmission disk 3. When the transmission disk 3 is driven by the drive motor, each stacked component 5 enters the feeding area in sequence. The feeding area is equipped with a proximity switch sensor 12, which is used to detect the induction trigger fixed on the outer periphery of the transmission disk 3. When an induction trigger enters the sensing range of the sensor as the transmission disk 3 rotates, the sensor outputs a detection signal to the control system. The control system then controls the drive motor to stop running, thereby stopping the transmission disk 3 at the predetermined feeding position, achieving precise positioning of the current stacked component 5.

[0064] After the stacking assembly 5 is positioned, the lifting mechanism 6 is activated. The drive motor inside the lifting mechanism 6 drives the active pulley 20 to rotate, which in turn drives the driven pulley 19 to rotate via the synchronous transmission belt 21, thereby causing the lead screw 15 to rotate vertically. The lead screw 15 is threadedly connected to the second lifting plate 16, and the rotation of the lead screw 15 causes the second lifting plate 16 to rise along the vertical direction defined by the guide rod 17. The three top rods 18 set on the second lifting plate 16 are distributed at equal angles, with their upper ends aligned with the bottom of the chassis 7 of the stacking assembly 5 in the feeding area.

[0065] As the push rod 18 rises synchronously, its upper end passes through the second through hole 11 of the transmission disc 3 and the corresponding first through hole 10 on the chassis 7, and contacts the bottom of the first lifting plate 9. When the push rod 18 continues to rise, the first lifting plate 9 is lifted, which in turn pushes the remaining stacked driven gears above it upwards until the uppermost driven gear reaches the set feeding height position for material handling machinery or manual grabbing.

[0066] After material handling is completed, the control system reverses the lifting mechanism 6, causing the top rod 18 to descend and reset, and the first lifting plate 9 descends to its initial position. Then, the control system starts the first drive motor 2, and the transmission disc 3 continues to rotate. The next set of stacked components 5 enters the feeding area, and the above process is repeated. The omnidirectional conveyor ball 24 is positioned along the outer edge of the bottom of the transmission disc 3 to provide bottom support and reduce friction during rotation, ensuring smooth rotation and transmission efficiency.
