[0033] The automated pre-heating production process for long shaft gears includes:
[0034] In the first step, the gantry robot 2 picks up the workpiece 7 that has been processed by the lathe 1;
[0035] The second step is for the gantry robot 2 to transport the workpiece 7 to the marking station 3 and complete the marking.
[0036] The third step involves the six-axis robot 4 gripping the workpiece 7 and transferring it to the cleaning mechanism 5 for cleaning.
[0037] The fourth step involves the six-axis robot 4 placing the cleaned workpiece 7 into the inspection station 8 to inspect the inner hole.
[0038] Fifth step: After the inspection is completed, the six-axis robot 4 loads the workpiece 7 onto the broaching machine 9 for processing;
[0039] Step 6: The six-axis robot 4 picks up the processed workpiece 7 and puts it into the unloading bin 6.
[0040] Among them, the gantry robot 2 is existing technology, capable of horizontal movement, and its gripping part is used to grip the workpiece 7. A gripper adapted to the workpiece 7 can be installed on the gripping part. The marking station 3 is existing technology and can be a manual or automated marking device. The inspection station 8 is existing technology and can be manually or automatically inspected. At both the marking station 3 and the inspection station 8, the workpiece 7 is gripped by the six-axis robot 4, and a corresponding gripper can be installed on the six-axis robot 4. The broaching machine 9 is existing technology and is used to broach the workpiece 7. The unloading bin 6 centrally stores the processed workpiece 7. The workpiece 7 is a long-shaft gear, meaning its teeth are set on the circumferential surface of a shaft.
[0041] like Figure 1The automated pre-heating production line for long-shaft gears includes a lathe 1, a gantry robot 2, a marking station 3, a six-axis robot 4, a cleaning mechanism 5, a material unloading bin 6, an inspection station 8, and a broaching machine 9. The six-axis robot 4 is arranged at one end of the gantry robot 2, and multiple lathes 1 are respectively arranged on both sides of the gantry robot 2. The unloading end of the lathe 1 is located within the gripping range of the gantry robot 2. The marking station 3 is located on the movement path of the gantry robot 2. The cleaning mechanism 5, the material unloading bin 6, the inspection station 8, and the broaching machine 9 are distributed in a ring around the six-axis robot 4 and are within the working radius of the six-axis robot 4.
[0042] Specifically, lathes 1 are distributed on both sides of the gantry robot 2. The lathes 1 are existing technologies, such as EMAG twin-spindle inverted lathes. The lathes 1 are distributed on both sides of the gantry robot 2. Two gantry robots 2 can be set up, with one gantry robot 2 corresponding to one row of lathes 1. The main purpose of the lathes 1 is to perform machining on the workpiece 7 before heating.
[0043] The production process and line of this invention achieve full automation from precision forging of long-shaft half-shaft gears to pre-heat finished products. This facilitates product traceability. The process, which previously required at least three people and involved multiple steps, is now automated, eliminating the need for manual operation. This reduces space occupation, turnover frequency, and work-in-process inventory, resulting in a highly efficient, stable, and multi-model modern automated production line.
[0044] like Figure 2 The present invention also relates to a cleaning mechanism for automated pre-heating production of long shaft gears, including a housing 501, a conveyor belt device 504, a fixed base 505, an outer cleaning component 507, an arc-shaped limiting plate 511, and an inner hole cleaning component; the conveyor belt device 504 is located inside the housing 501, and the outer cleaning component 507 is provided on the top of the housing 501.
[0045] The outer cleaning component 507 is located above the conveyor belt device 504 and is used to clean the outer surface of the workpiece 7. Multiple fixing seats 505 are installed on the outer surface of the conveyor belt device 504. The fixing seats 505 are used to insert and place the workpiece 7. The arc-shaped limiting plate 511 is arranged in the conveying direction of the conveyor belt device 504. The inner wall of the arc-shaped limiting plate 511 is located at the rotation radius of the workpiece 7 and is used to limit the workpiece 7 to be held on the fixing seat 505, so that the workpiece 7 moves from the upper surface to the lower surface of the conveyor belt device 504. The inner hole cleaning component is located at the bottom of the arc-shaped limiting plate 511. When the workpiece 7 falls off the arc-shaped limiting plate 511, it falls onto the inner hole cleaning component. The inner hole cleaning component is used to clean the inner hole of the workpiece 7.
[0046] The conveyor belt device 504 is existing technology and can be used for chain conveying, belt conveying, etc. A fixed base 505 is fixedly mounted on the conveying part of the conveyor belt device 504. The conveyor belt device 504 is horizontally positioned. The conveyor belt device 504 operates periodically, and the distance conveyed in each rotation is the distance between two adjacent fixed bases 505. That is, each time the conveyor belt device 504 moves, two adjacent fixed bases 505 move forward one interval. During this process, the six-axis robot 4 sequentially inserts and places the workpiece 7 onto the fixed base 505. During the conveying process of the conveyor belt device 504, the outer cleaning component 507 cleans the outer surface of the workpiece 7. The inner arc portion of the arc-shaped limiting plate 511 is adapted to the rotation radius of the fixed base 505 at the end of the conveyor belt device 504. During the rotation of the fixed base 505, the arc-shaped limiting plate 511 abuts against the workpiece 7, keeping the workpiece 7 on the fixed base 505. When the fixed seat 505 rotates to a position below the conveyor belt device 504, the workpiece 7 slides downwards and falls onto the inner hole cleaning component under its own weight, and the inner hole cleaning component cleans the inner hole of the workpiece 7 shaft portion.
[0047] The cleaning mechanism of the present invention can clean the outer surface of the workpiece 7 during the transportation process of the conveyor belt device 504. When the workpiece 7 moves to the bottom of the conveyor belt device 504, it falls onto the inner hole cleaning component, thereby cleaning the inner hole of the workpiece 7. Thus, the present invention can effectively clean the inner and outer sides of the workpiece 7, and the whole process is automatic, achieving the purpose of automated cleaning.
[0048] like Figure 3 , Figure 4 Furthermore, the outer cleaning component 507 includes a motor 5074, a brush roller 5073, a main shaft 5072, and a nozzle 5075. The motor 5074 is fixedly mounted on the top of the housing 501, and its output end is fixedly connected to the main shaft 5072. The brush roller 5073 is sleeved on the main shaft 5072 and contacts the outer side of the workpiece 7. The nozzle 5075 is positioned above the brush roller 5073 and the workpiece 7. The outer contour of the brush roller 5073 is adapted to the workpiece 7, and can fit the teeth and shaft portion of the workpiece 7. The nozzle 5075 is prior art, and its spray direction is towards the position between the workpiece 7 and the brush roller 5073. The nozzle 5075 is connected to a corresponding pump body and water tank, spraying cleaning fluid, clean water, etc., onto the contact position between the brush roller 5073 and the workpiece 7.
[0049] Furthermore, multiple outer cleaning components 507 can be arranged in the conveying direction of the conveyor belt device 504, and the nozzles 5075 on the multiple outer cleaning components 507 can form a series structure. Multiple outer cleaning components 507 achieve the purpose of multiple cleaning.
[0050] Furthermore, the fixed base 505 includes a fixed block 5051, a driven tooth 5052, and a pin 5053; the fixed block 5051 is fixedly connected to the outer surface of the conveyor belt device 504, the side of the fixed block 5051 away from the conveyor belt device 504 is fixedly connected to the pin 5053, the driven tooth 5052 is fixedly connected to the pin 5053, the pin 5053 is used to insert into the inner hole of the workpiece 7, and the bottom of the workpiece 7 abuts against the driven tooth 5052; the outer cleaning component 507 also includes a driving tooth 5071, the driving tooth 5071 is fixedly connected to the spindle 5072, and the driving tooth 5071 meshes with one of the driven teeth 5052 on the fixed base 505.
[0051] Workpiece 7 is placed onto pin 5053 by a six-axis robot 4, thus fitting onto pin 5053. Driven tooth 5052 supports workpiece 7. During the periodic operation of the conveyor belt device 504, driven tooth 5052 sequentially meshes with driving tooth 5071, meaning driving tooth 5071 is located on the movement path of driven tooth 5052. During the cleaning process of the outer cleaning component 507, motor 5074 drives driving tooth 5071 and driven tooth 5052 to rotate relative to each other, causing workpiece 7 to rotate relative to brush roller 5073. Friction is generated at the contact points, improving the cleaning effect. Different tooth ratios can be set for driving tooth 5071 and driven tooth 5052 to achieve relative rotational friction between workpiece 7 and brush roller 5073.
[0052] Furthermore, the fixed base 505 also includes an elastic sleeve 5054, the top of the pin 5053 is fixedly connected to the elastic sleeve 5054, the top of the housing 501 is fixedly installed with a lifting device 510, the output end of the lifting device 510 is rotatably connected to a connecting pin 5083, the diameter of the connecting pin 5083 is larger than the inner diameter of the elastic sleeve 5054, the connecting pin 5083 is coaxially distributed with one of the elastic sleeves 5054, the lifting device 510 is used to push the connecting pin 5083 into the elastic sleeve 5054, so that the elastic sleeve 5054 presses the inner wall of the workpiece 7, thereby causing the pin 5053 to drive the workpiece 7 to rotate.
[0053] The lifting device 510 is existing technology, such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder. The output end of the lifting device 510 is fixedly connected to a connecting plate 509. Multiple insertion pins 5083 are fixedly connected to the connecting plate 509, their number matching the number of external cleaning components 507 and their corresponding positions. The insertion pins 5083 are vertically arranged and located above the housing 501. During the lifting process of the lifting device 510, the insertion pins 5083 insert into or disengage from the inner hole of the workpiece 7, and insert into and pull out the elastic sleeve 5054. The elastic sleeve 5054 can be a rubber sleeve. The diameter of the insertion pin 5083 is smaller than the inner hole diameter of the workpiece 7 but larger than the inner diameter of the elastic sleeve 5054. When the insert pin 5083 is inserted into the elastic sleeve 5054, the elastic sleeve 5054 is compressed and expanded, thereby generating a compressive force on the inner wall of the workpiece 7, applying a circumferential constraint to the workpiece 7. Under the action of this circumferential constraint, the insert pin 5083, the elastic sleeve 5054, and the pin 5053 rotate together. Thus, the rotation of the pin 5053 drives the workpiece 7 to rotate, achieving the purpose of the workpiece 7 and the brush roller 5073 rotating together. At the same time, the circumferential constraint is achieved through the elastic sleeve 5054, and the pin 5053 and the workpiece 7 can be in clearance fit, which facilitates positioning and allows the workpiece 7 to fall downwards. Furthermore, the pin 5053 does not need to be in spline fit with the inner hole of the workpiece 7, so the purpose of driving the workpiece 7 to rotate can be achieved regardless of whether the inner hole of the workpiece 7 has a spline or other positioning structure.
[0054] Furthermore, the arc-shaped limiting plate 511 limits the tooth end face portion of the workpiece 7.
[0055] The arc-shaped limiting plate 511 can be fixedly connected to the inner walls of both sides of the housing 501. Two arc-shaped limiting plates 511 can be provided, with the two arc-shaped limiting plates 511 spaced apart. The gap between the two plates passes through the shaft portion of the workpiece 7, while the toothed end face portion of the workpiece 7 abuts against the inner side of the arc-shaped limiting plate 511. A rubber pad can be provided on the inner side of the arc-shaped limiting plate 511 to prevent scratching the workpiece 7.
[0056] like Figures 5-7 The internal cleaning component includes a turntable 514, an internal nozzle 512, and a hollow seat 513. Multiple hollow seats 513 are arranged in the circumferential direction of the turntable 514. The interior of each hollow seat 513 is adapted to the workpiece 7. One of the hollow seats 513 is located below the bottom end of the arc-shaped limiting plate 511 and is used to catch the workpiece 7 falling from the arc-shaped limiting plate 511. The internal nozzle 512 is located above one of the hollow seats 513 and is coaxially arranged.
[0057] A turntable 514 is rotatably mounted on a base 515. A motor can be installed inside the base 515, and the motor output is fixedly connected to the turntable 514, thereby realizing the rotation of the turntable 514. The turntable 514 rotates periodically, and at the same frequency as the conveyor belt device 504. After each rotation of the conveyor belt device 504, the fixed seat 505 passes sequentially through one of the hollow seats 513, aligning the workpiece 7 with the hollow seat 513, forming... Figure 6 The workpiece 7 then slides down from the hollow seat 513 and enters the interior of the hollow seat 513, where the hollow seat 513 supports the toothed end face of the workpiece 7. Then the turntable 514 rotates, and the next hollow seat 513 moves to the bottom of the arc-shaped limiting plate 511, ready to receive the workpiece 7 conveyed by the conveyor belt device 504 at the next moment.
[0058] The inner nozzle 512 and the hollow seat 513 that receives the workpiece 7 are preferably located at both ends of the turntable 514. The inner nozzle 512 is aligned with the inner hole of the workpiece 7 and sprays cleaning fluid, water, etc. to clean the inner hole of the workpiece 7. The inner nozzle 512 is connected to the corresponding pump body and water tank.
[0059] Furthermore, the top of the housing 501 is provided with a first opening 506 and the side is provided with a second opening 516 for input and output of the workpiece 7.
[0060] Specifically, the six-axis robot 4 places the workpiece 7 onto the fixed seat 505 through the first opening 506, and removes the workpiece 7 from the hollow seat 513 through the second opening 516. A portion of the turntable 514 extends out of the second opening 516 to facilitate the removal of the workpiece 7.
[0061] Furthermore, the rollers of the conveyor belt device 504 are rotatably connected to the inner side of the housing 1 to fix the conveyor belt device 504. A filter plate 502 is provided at the bottom of the housing 1, and a drainage chamber 503 is provided below the filter plate 502. Wastewater is accumulated in the drainage chamber 503 and discharged. The filter plate 502 is used to filter impurities. A turntable 514 is rotatably mounted on the filter plate 502, and a base 515 is located below the filter plate 502.
