Description

Technical Field

[0001] This invention relates to the field of gear processing technology, and in particular to an automated loading and unloading conveying device for gear processing. Background Technology

[0002] Gears, as a core component of mechanical transmission, are widely used in automobiles, construction machinery, precision equipment, and other fields. In gear manufacturing production lines, the loading and unloading of raw and finished parts directly affects production efficiency, processing accuracy, and automation levels. Currently, the industry commonly uses manual-assisted loading and unloading or simple conveyor lines combined with independent loading mechanisms, which has the following significant drawbacks: The existing loading and unloading mechanism lacks stability in gear stacking and positioning. Gears are prone to deviation and tilting during conveying or pushing, leading to malfunctions such as jamming and inaccurate feeding, which affects the continuous operation of the production line. Moreover, the pushing action and the conveyor belt operation are independent of each other and asynchronous in frequency, making it easy for gears to accumulate randomly and fall onto the conveyor belt in an disorderly manner. It is impossible to achieve orderly pushing of stacked gears and accurate landing on the conveyor belt, which makes it difficult to guarantee the cycle matching and positioning accuracy of subsequent processing stations, thus restricting the automation connection and processing efficiency of the entire production line. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides an automated loading and unloading conveying device for gear processing, which effectively solves the problems of unstable positioning, asynchronous pushing and conveying, and disordered material dropping in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automated loading and unloading conveyor for gear processing includes a frame with a driveable conveyor belt mounted on it. A base plate is fixedly mounted at one end of the frame, and a mounting plate that reciprocates and slides on the base plate. A sliding plate is fixedly mounted at the front end of the mounting plate and is slidably connected to the upper surface of the base plate. A positioning mechanism is also provided on the base plate, comprising mounting frames respectively located at both ends of the base plate and slidable towards each other. Vertical sliding rods for vertically limiting the gears are mounted at both ends of the mounting frames. Sliding groove rods for adapting to the gear diameter are slidably mounted at both ends of the sliding plate. A first pin is fixedly mounted at a corresponding end of the mounting frame and is slidably disposed in a groove opened at the front end of the sliding groove rod.

[0005] The frame is rotatably connected to a first friction wheel and a second friction wheel at both ends, and the conveyor belt is wound around the first friction wheel and the second friction wheel at both ends. A motor is fixedly installed at one end of the frame, and the output end of the motor is drivenly connected to the first friction wheel.

[0006] A transmission rod is fixedly installed on the first friction wheel, and the transmission rod is rotatably connected to the frame; a driving bevel gear is fixedly installed at one end of the transmission rod, and the driving bevel gear meshes with a driven bevel gear, and a turntable is coaxially fixedly connected to the driven bevel gear; a second pin is fixedly installed at the non-center of the turntable, and a traction rod is rotatably connected to the second pin, and one end of the traction rod is rotatably connected to the mounting plate.

[0007] The lower ends of the substrate are respectively fixedly connected to the two sides of the second limiting rod, and the two ends of the mounting plate are respectively slidably sleeved on the second limiting rod.

[0008] The positioning mechanism also includes a lead screw, which is rotatably connected to the base plate; the two ends of the lead screw are provided with reverse threads, which respectively engage with the mounting brackets on both sides; one end of the lead screw is provided with a handle; a first limiting rod is fixedly provided on the base plate, and the inner wall of the mounting bracket slides in cooperation with the first limiting rod.

[0009] A third limiting rod is fixedly installed on the slide plate, and the slide rail is slidably sleeved on the third limiting rod.

[0010] The vertical slide bar is a straight, vertically set rod. Multiple vertical slide bars are arranged in a ring to form a gear stacking station. The gears are coaxially sleeved on the inner side of the ring enclosed by the vertical slide bars to achieve vertical stacking and positioning of the gears.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: The traction rod oscillates back and forth with the circular motion of the second pin, thereby pulling the mounting plate to slide horizontally back and forth along the surface of the substrate. When the mounting plate slides forward, it drives the front slide plate to move forward synchronously. The sliding rods at both ends of the slide plate move forward with the slide plate. At the same time, because a groove is formed between the sliding rods, and the depth of the groove is the same as the thickness of a single gear, the groove at the front end of the slide plate precisely pushes the bottom single gear on the stacked gears on the vertical slide rod, overcoming the stacking friction between the gears and pushing the single gear out of the stacking station. When the mounting plate slides back to reset, the slide plate moves backward synchronously. The remaining stacked gears on the vertical slide rod automatically fall into the groove between the sliding rods under the action of gravity, filling the position at the pushing station and preparing for the next pushing. This achieves the orderly pushing out of the gears one by one. The single gear pushed out by the slide plate falls precisely onto the surface of the synchronously running conveyor belt. Because the pushing action and the operation of the conveyor belt are completely linked and synchronized, the gear dropping position is fixed and the posture is regular, and there will be no messy accumulation or disorderly dropping on the belt. The conveyor belt continues to operate, smoothly and orderly transporting the gears that fall on it to the subsequent gear processing station. Attached Figure Description

[0013] like Figure 1-7 An automated loading and unloading conveyor device for gear processing is shown, comprising a frame 1, on which a driveable conveyor belt 3 is mounted. A base plate 4 is fixedly mounted at one end of the frame 1. A mounting plate 17 is provided on the base plate 4 and slides back and forth with it. A sliding plate 26 is fixedly mounted at the front end of the mounting plate 17 and slides with the upper surface of the base plate 4. The base plate 4 is also provided with a positioning mechanism, which includes mounting frames 14 respectively located at both ends of the base plate 4 and slidable towards each other. Vertical sliding rods 5 for vertically limiting gears 7 are respectively mounted at both ends of the mounting frames 14. Sliding groove rods 20 for adapting to the diameter of gears 7 are slidably provided at both ends of the sliding plate 26. A first pin 19 is fixedly mounted at the corresponding end of the mounting frame 14 and slides within a groove 22 opened at the front end of the sliding groove rod 20.

[0014] Several support seats 2 are provided at the lower end of the frame 1, and the support seats 2 play a role in supporting and fixing the frame 1.

[0015] The two ends of the frame 1 are rotatably connected to a first friction wheel 15 and a second friction wheel 24, respectively. The two ends of the conveyor belt 3 are respectively wound around the first friction wheel 15 and the second friction wheel 24. A motor 6 is fixedly installed at one end of the frame 1, and the output end of the motor 6 is drivenly connected to the first friction wheel 15.

[0016] like Figure 7As shown, the output end of the motor 6 drives the first friction wheel 15 to rotate. The first friction wheel 15 and the second friction wheel 24 drive the conveyor belt 3 to rotate smoothly through friction, thus conveying the gear 7.

[0017] A transmission rod 16 is fixedly installed on the first friction wheel 15, and the transmission rod 16 is rotatably connected to the frame 1; a driving bevel gear 8 is fixedly installed at one end of the transmission rod 16, and the driving bevel gear 8 meshes with a driven bevel gear 9, and the driven bevel gear 9 is coaxially fixedly connected to a turntable 10; a second pin 23 is fixedly installed at the non-center of the turntable 10, and a traction rod 25 is rotatably connected to the second pin 23, and one end of the traction rod 25 is rotatably connected to the mounting plate 17.

[0018] like Figure 2 and 3 As shown in Figure 7, motor 6 drives the first friction wheel 15 to rotate, and the first friction wheel 15 drives the transmission rod 16 to rotate synchronously; the driving bevel gear 8 at the end of the transmission rod 16 rotates accordingly, meshing and driving the driven bevel gear 9 to rotate, and the driven bevel gear 9 drives the coaxial turntable 10 to perform uniform circular motion; the second pin 23 at the eccentric position of the turntable 10 moves in a circular motion with the turntable 10, pulling the traction rod 25 to swing back and forth; the other end of the traction rod 25 pulls the mounting plate 17 to perform horizontal reciprocating linear motion along the base plate 4; the mounting plate 17 drives the slide plate 26 to slide back and forth synchronously, so as to push the bottom gear 7 forward one by one. The pushing action is strictly synchronized with the operation of the conveyor belt 3 to ensure that the gear 7 falls accurately and orderly onto the conveyor belt 3.

[0019] The lower ends of the substrate 4 are respectively fixedly connected to the two sides of the second limiting rod 18, and the two ends of the mounting plate 17 are respectively slidably sleeved on the second limiting rod 18.

[0020] like Figure 3 As shown, the second limiting rod 18 guides the slide plate 26 linearly through the mounting plate 17, so that the slide plate 26 can only slide back and forth in the horizontal direction, preventing left and right deviation or tilting, and ensuring that the pushing direction is accurate and does not deviate.

[0021] The positioning mechanism also includes a lead screw 12, which is rotatably connected to the base plate 4; the two ends of the lead screw 12 are provided with reverse threads, which respectively engage with the mounting brackets 14 on both sides; one end of the lead screw 12 is provided with a handle 11; a first limiting rod 13 is fixedly provided on the base plate 4, and the inner wall of the mounting bracket 14 slides with the first limiting rod 13.

[0022] like Figure 2As shown, the lead screw 12 has reverse threads at both ends, and a handle 11 is provided at one end of the lead screw 12. By rotating the lead screw 12 through the handle 11, the mounting brackets 14 on both sides can move synchronously towards or away from each other, ensuring that the annular center of the vertical slide rod 5 remains unchanged, and realizing the rapid and coaxial centering of gears 7 with different diameters. At the same time, the synchronous back-to-back movement of the mounting brackets 14 drives the second pin 23 to move towards both ends. The second pin 23, in conjunction with the third limit rod 21, drives the slide bar 20 to move, thereby adjusting the width of the groove formed between the slide bars 20, and the groove at the front end of the slide plate 26 is precisely accommodated. The bottommost single gear 7 of the stacked gears 7 on the vertical slide bar 5 is pushed out of the stacking station by the sliding plate 26 at the front end of the groove to overcome the stacking friction between the gears 7. The purpose of the slide groove 22 at the front end of the slide bar 20 is to effectively prevent the second pin 23 from limiting the push of the slide bar 20 and the gear 7. The first limiting rod 13 plays a linear guiding and anti-rotation limiting role for the mounting frame 14, so that the mounting frame 14 can only move radially without rotating or tilting, ensuring that the vertical slide bar 5 is always vertical and circular.

[0023] A third limiting rod 21 is fixedly installed on the slide plate 26, and the slide rail 20 is slidably sleeved on the third limiting rod 21.

[0024] like Figure 4 As shown, the third limiting rod 21 is used to limit the sliding rod 20, ensuring that the sliding rod 20 can only slide along the axial direction of the third limiting rod 21, thereby adjusting the spacing of the grooves formed between the sliding rods 20 to accommodate the pushing of gears 7 of different diameters.

[0025] The vertical slide bar 5 is a vertically set smooth bar. Multiple vertical slide bars 5 are arranged in a ring to form a gear 7 stacking station. The gear 7 is coaxially sleeved on the inner side of the ring enclosed by the vertical slide bars 5 to realize the vertical stacking limit of the gear 7.

[0026] like Figure 2 As shown, multiple vertical sliding rods 5 form a ring around the outer circle of the gear 7, allowing the gear 7 to slide up and down along the sliding rods. This prevents the gear from tilting, tipping over, or jamming during stacking, ensuring that the stacked posture remains vertical and coaxial. The ring also forms a central positioning hole, into which the gear 7 is coaxially inserted, ensuring that the center of each gear 7 is aligned and has good concentricity. This results in uniform force distribution during pushing, preventing deviation or offset, and ensuring precise feeding position.

[0027] The working process of this invention is as follows: The blank of the gear 7 to be processed is coaxially and vertically stacked on the outside of multiple vertical sliding rods 5. The gears 7 are stacked layer by layer, and the vertical sliding rods 5 form a vertical limit on the gears 7, preventing them from tilting or shifting during stacking, forming a regular stack of gears 7. The motor 6 is started, driving the first friction wheel 15 to rotate. The first friction wheel 15 drives the conveyor belt 3 to rotate synchronously around the second friction wheel 24, realizing continuous conveying operation of the conveyor belt 3. Simultaneously, the first friction wheel 15 drives the transmission rod 16 to rotate coaxially, and the driving bevel gear 8 at the end of the transmission rod 16 rotates accordingly. The driving bevel gear 8 meshes and drives the driven bevel gear 9 to rotate, and the driven bevel gear 9 drives the coaxially fixed turntable 10 to rotate synchronously, completing the synchronous transmission of power. This links the operation of the conveyor belt 3 with the pushing action of the slide plate 26, fundamentally avoiding the problem of asynchronous pushing and conveying actions. When the turntable 10 continues to rotate, the second pin 23 fixed at its non-center position... In a circular motion, the traction rod 25 swings back and forth with the circular motion of the second pin 23, thereby pulling the mounting plate 17 to slide horizontally back and forth along the surface of the base plate 4. When the mounting plate 17 slides forward, it drives the front slide plate 26 to move forward synchronously. The sliding rods 20 at both ends of the slide plate 26 move forward with the slide plate 26. At the same time, since a groove is formed between the sliding rods 20, and the depth of the groove is the same as the thickness of a single gear 7, the groove at the front end of the slide plate 26 accurately pushes the bottom single gear 7 of the stacked gears 7 on the vertical slide rod 5, overcoming the stacking friction between the gears 7, and pushing the single gear 7 out of the stacking station. When the mounting plate 17 slides back to reset, the slide plate 26 moves backward synchronously. The remaining stacked gears 7 on the vertical slide rod 5 automatically fall into the groove between the sliding rods 20 under the action of gravity, filling the position at the pushing station, and preparing for the next pushing, so as to realize the orderly pushing out of the gears 7 one by one. The single gear 7 pushed out by the slide plate 26 falls precisely onto the surface of the synchronously operating conveyor belt 3. Because the pushing action is fully synchronized with the operation of the conveyor belt 3, the gear 7 has a fixed drop position and a regular posture, and there will be no messy accumulation or disorderly drop. The conveyor belt 3 continues to operate, smoothly and orderly transporting the gear 7 that has fallen on it to the subsequent gear 7 processing station, completing the automated feeding and conveying process. The above pushing, dropping and conveying actions are repeated in a cycle, continuously transporting the gear 7 stacked at the station to the processing station one by one.
