Description

Technical Field

[0001] This utility model relates to the technical field of machining facilities for shaft parts, specifically an automatic loading and unloading integrated system for a gantry grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses abrasives to grind workpieces to obtain the desired shape, size, and precision machined surfaces. When grinding shaft parts, each shaft part to be processed needs to be placed in the processing position, and then the operator places each part into the grinding machine for processing. During the processing, the shaft diameter also needs to be measured and recorded. After the accuracy requirements are met, qualified products need to be marked. In this process, on the one hand, because several shaft parts to be processed are stacked together, it is inconvenient to pick up and drop the parts, which affects the processing efficiency and production efficiency. On the other hand, when the parts are taken out, the cutting fluid adhering to the surface needs to be cleaned, and the diameter of each shaft part needs to be measured and qualified products need to be marked. This not only makes it inconvenient for the operator to operate and increases the labor intensity of the operator, but also poses a risk of scratching the parts, resulting in high labor costs.

[0003] Currently, a large part of industrial automation in grinding processes still relies on manual loading and unloading or semi-automatic processes. The efficiency and quality of loading and unloading, as well as the prevention of misoperation and error-proofing, are insufficient to meet the needs of industrial automated production.

[0004] Therefore, an integrated automatic loading and unloading system for grinding machines is needed to solve the above problems. Utility Model Content

[0009] Furthermore, the movable module is used to adjust the position of the laser diameter measuring instrument. The movable module includes a movable cylinder connected to the top surface of the cabinet, a guide rail installed on the top surface of the cabinet, and a movable block slidably connected to the guide rail and driven by the movable cylinder to move left or right.

The system comprises a feeding conveyor 7, a transfer conveyor 16, a discharging conveyor 8, a laser diameter gauge 14, and a marking machine 15. The marking machine 15 is located above the laser diameter gauge 14. The feeding conveyor 7 is used to transport the material bars of shaft parts to be processed. A moving module 13 is provided between the bottom end of the laser diameter gauge 14 and the top surface of the cabinet 11. The moving module 13 is used to adjust the position of the laser diameter gauge 14. The moving module 13 includes a moving cylinder 1301 connected to the top surface of the cabinet 11 and a guide installed on the top surface of the cabinet 11. The guide rail 1302 and the moving block 1303, which is slidably connected to the guide rail 1302 and driven to move left or right by the moving cylinder 1301, are mounted on the moving block 1303.

It consists of the second upright plate 203 and the horizontal plate 201 placed on the first upright plate 202 and the second upright plate 203. The horizontal plate 201 has a straight module 3 installed on its front along its length. The truss body 2 adopts a gantry truss. Among them, the robot arm 6 refers to an automatic operating device that can imitate certain movement functions of human hands and arms to grasp, transport objects or operate tools according to a fixed program. It mainly consists of three parts: the execution mechanism, the drive mechanism and the control system. The robot arm 6 is a well-known technology in the market, so it will not be described in detail here.

[0019] It should be noted that both the feeding conveyor 7 and the unloading conveyor 8 are arranged along the length of the cabinet 11. The bottom of the material bar output position of the feeding conveyor 7 is equipped with a lifting mechanism 18 for lifting the material bar. The lifting mechanism 18 consists of an upper lifting cylinder 1801 installed inside the cabinet storage cavity 17 and a top plate 1802 installed at the movable end of the upper lifting cylinder 1801. The top surface of the cabinet 11 is equipped with a hopper 9 for storing defective material bars located to the right of the unloading conveyor 8. The feeding conveyor 7, the transfer conveyor 16 and the unloading conveyor 8 all use, but are not limited to, TD75 type belt conveyors.

[0020] In this embodiment, the air knife dehydration device 4 is located below the horizontal plate 201 and mounted on the grinding machine 1. The air knife dehydration device 4 is used to remove cutting fluid from the surface of the bar. The air knife dehydration device 4 consists of a blower 401, a bracket 402 slidably connected to it, and at least one set of air knife assemblies 403 mounted on the bracket 402. The material handling unit 5 is located above the loading and unloading unit and is movably connected to the linear module 3. The material handling unit 5 includes a mounting frame 501, and correspondingly distributed and vertically placed material handling mechanisms 502 and transfer material handling mechanisms 504 on both sides inside the mounting frame 501. The top and bottom of the mounting frame 501 are both open structures. The linear module 3 adopts a ball screw type linear module or a synchronous belt type linear module. The linear module 3 is used to drive the material handling unit 5 to move horizontally to the left or right to the material handling point of the bar. Preferably, the linear module 3 adopts a ball screw type linear module to drive the material handling unit 5 to move horizontally to the left or right, that is, the material handling unit 5 moves towards the grinding machine 1 or towards the loading / unloading unit; the linear module 3 has several names, such as linear module, Cartesian coordinate robot, linear slide, etc. It is an automation upgrade unit following linear guide rails and ball screw linear transmission mechanisms. It can realize the linear motion of the load through the combination of various units. The structure and principle of the linear module 3 are well-known technologies in the market, so they will not be described in detail here; it should be noted that the working principle of the air knife dewatering device 4 is mainly based on the impact of high-speed airflow and the special structural design of the air knife. It forms a high-intensity airflow sheet by compressing air, which effectively removes moisture from the surface of the object or the production line; the fan 401 adopts, but is not limited to, the GY4-68 type fan.

[0021] The material handling mechanism 502 and the transfer material handling mechanism 504 are both composed of a vertical support plate 5021, a telescopic cylinder 5022 vertically placed in the mounting frame 501, and a movable rod 5023 slidably connected to the vertical support plate 5021. The piston rod of the telescopic cylinder 5022 is connected to the movable rod 5023 as one unit, and a cylinder gripper 503 is installed at the bottom end of the movable rod 5023. The operation of the telescopic cylinder 5022 drives the movable rod 5023 to move up and down to grip the material handling bar through the cylinder gripper 503. The working principle of the cylinder gripper 503 is mainly based on the piston movement driven by compressed air. The opening and closing action of the gripper is realized through a mechanical structure. That is, compressed air enters the cylinder through the air source pipe and pushes the piston to make reciprocating linear motion along the cylinder. The extension and retraction of the piston rod directly drives the opening and closing of the gripper or the actuating rod. Preferably, the cylinder gripper 503 adopts, but is not limited to, the SMC brand MHS series or MRHQ series cylinder gripper.

[0022] In this embodiment, a truss moving part 19 is installed at the bottom of both the first upright plate 202 and the second upright plate 203. The truss moving part 19 consists of a horizontally arranged base 1901, a horizontally opened moving slide rail 1902 on the base 1901, and a first slider 1903 slidably connected to the moving slide rail 1902. The first slider 1903 is integrally connected to the bottom of the first upright plate 202 or the second upright plate 203. The base 1901 is placed on the top surface of the grinding machine 1 or the cabinet 11. A truss fine-tuning part 20 is installed on the grinding machine 1 near the air knife dewatering device 4. The truss fine-tuning part 20 cooperates with the truss moving part 19 to determine the usage position of the truss body 2. The truss fine-tuning part 20 consists of a base plate 2001 and a second slider 2002 slidably connected to the base plate 2001. The system consists of a locking screw 2003 for locking the position of the second slider 2002. The second slider 2002 is fixedly connected to the bracket 402. The position of the truss body 2 on the grinding machine 1 can be finely adjusted to the left or right using the truss moving part 19 according to the needs of using different sized bars. After the position of the truss body 2 on the grinding machine 1 is determined after the fine adjustment, the bracket 402 is fixedly connected to the first upright plate 202 or the second upright plate 203, and the second slider 2002 is fixedly connected to the bracket 402. Thus, the second slider 2002 can be fixed to the base plate 2001 using the locking screw 2003. In this way, the air knife dewatering device 4 and the truss body 2 are firmly restricted on the grinding machine 1. At this time, the truss body 2 stands steadily above the grinding machine 1.

[0023] This automatic loading and unloading integrated system for gantry grinding machines is used according to the following procedures; Material placement process: First, place the material bars of the shaft parts to be ground in sequence on the feeding conveyor 7. The feeding conveyor 7 runs and transports the material bars to the lifting mechanism 18. The lifting mechanism 18 lifts the material bars to the picking point, that is, the lifting cylinder 1801 runs and drives the top plate 1802 to lift the material bars upward. Material handling process: After the cylinder gripper 503 of the material handling mechanism 502 drives the movable rod 5023 to descend to the material handling point through the telescopic cylinder 5022, it starts and clamps the material bar through the cylinder gripper 503. Then the telescopic cylinder 5022 rises and retracts, driving the cylinder gripper 503 back to the original position to complete the material handling action. Material bar processing procedure: After the material picking action is completed, the material picking and placing mechanism 502 is moved to the grinding station on the grinding machine 1 by starting the linear module 3. Then, the movable rod 5023 is driven down by the telescopic cylinder 5022 to place the material bar held by the cylinder chuck 503 on the grinding station. The telescopic cylinder 5022 is retracted to drive the cylinder chuck 503 to rise back to its original position. Then, the grinding machine 1 is started again to start grinding the material bar. Transfer feeding and secondary material handling process: After the material bar grinding is completed, the transfer feeding mechanism 504 is moved to the grinding station via the linear module 3. The telescopic cylinder 5022 of the transfer feeding mechanism 504 descends to allow the cylinder gripper 503 to grasp the ground material bar at the grinding station. After grasping, the telescopic cylinder 5022 of the transfer feeding mechanism 504 rises back to its original position, and the transfer feeding mechanism 504 is moved to the transfer feeding point on the transfer conveyor 16 via the linear module 3. Simultaneously, the telescopic cylinders 5022 of the intermediate material handling mechanism 504 and the material handling mechanism 502 descend. After the intermediate material handling mechanism 504 places the processed material bar on the transfer conveyor 16 to complete the intermediate material handling action, the telescopic cylinder 5022 causes the cylinder grippers 503 of the material handling mechanism 502 and the cylinder grippers 503 of the intermediate material handling mechanism 504 to rise back to their original positions. Then, the material handling mechanism 502 performs the material handling step of the material handling process, thereby completing the automatic feeding and unloading of the material bar. Diameter measurement and laser printing process: The conversion conveyor 16 transports the processed material bar to the picking position of the six-axis robot. The robot's manipulator 6 picks up the material bar and places it at the position of the laser diameter gauge 14 and the marking machine 15 for diameter measurement and marking. Before diameter measurement, the laser diameter gauge 14 needs to be adjusted to a suitable position for the current material bar size using the moving module 13 according to the different material bar sizes. The laser diameter gauge 14 is used to measure the diameter of the material bar. The marking machine 15 marks the material bars that pass the diameter measurement. Material bars that fail the diameter measurement are temporarily placed on the hopper 9 by the six-axis robot. Finished product placement process: The six-axis robot marks the qualified material bars, clamps them, and places them on the unloading conveyor 8. The unloading conveyor 8 then transports the qualified material bars to the next process, completing the automatic diameter measurement and marking of the material bars. This process is repeated to produce large quantities of shaft-type parts in stock.

[0024] It should be noted that the telescopic cylinder 5022 adopts, but is not limited to, the ST-02 or HSGL type telescopic cylinder, and the moving cylinder 1301 and the lifting cylinder 1801 adopt, but are not limited to, the SC series cylinder. The cylinder structure and principle of the telescopic cylinder 5022, the moving cylinder 1301, and the lifting cylinder 1801 are well-known technologies in the market, and therefore will not be described in detail here. Among them, the laser diameter measuring instrument 14 adopts, but is not limited to, the BR71-LDM-10AXY or LMD-2 type laser diameter measuring instrument. The laser diameter measuring instrument 14 can adopt, but is not limited to, a CCD dimension measurement type. The laser diameter gauge or laser scanning measurement laser diameter gauge 14 has a structure and principle that are well-known technologies in the market, so they will not be described in detail here. The marking machine 15 mentioned uses a pneumatic, laser, or electromagnetic marking machine. The structure and principle of the marking machine 15 are well-known technologies in the market, so they will not be described in detail here. The six-axis robot mentioned uses, but is not limited to, a G4 six-axis industrial robot. The six-axis robot has six built-in servo motors that directly drive the rotation of the six joint axes through reducers, synchronous pulleys, etc. The six-axis robot generally has six degrees of freedom, including rotation / S-axis, lower arm / L-axis, upper arm / U-axis, wrist rotation / R-axis, wrist swing / B-axis, and wrist rotation / T-axis. The six joints combine to realize the six degrees of freedom of the end effector, which has many advantages such as high flexibility, ultra-large load, and high positioning accuracy.
