Description

Technical Field

[0001] This utility model belongs to the field of mounting technology, and in particular relates to a gear-suspended carburizing and quenching robot fully automatic mounting workstation. Background Technology

[0002] In critical transmission systems across numerous fields such as engineering machinery and automobiles, gearboxes play a vital role in transmitting torque and traction power. Among them, planetary gearboxes in engineering machinery are widely used due to their small size, compact structure, and high load-bearing capacity. During torque transmission, the gear teeth are constantly subjected to contact stress and bending stress. To improve the resistance to contact and bending fatigue of such parts, a strengthening heat treatment process of integral carburizing and quenching is usually adopted to achieve a surface hardness of 58HRC to 62HRC and a core hardness of 35HRC to 40HRC, thereby enhancing their comprehensive fatigue resistance mechanical properties. In existing technologies, gear heat treatment still uses a flat mounting method, resulting in uneven cooling on both sides of the gear during quenching and severe deformation at the gear ends. In addition, the use of multi-layer mounting makes it impossible to achieve automated robotic production, often resulting in high manpower and material costs and low efficiency.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] like Figure 1-6 As shown, the fully automatic clamping workstation of the gear-suspended carburizing and quenching robot of this utility model includes:

[0033] Suspended mounting heat treatment tray 1, used to receive gears mounted into the furnace;

[0034] Conveyor roller bed 2 is set at the bottom of the suspended mounting heat treatment pallet 1 and is used to support and convey the suspended mounting heat treatment pallet 1.

[0035] Two suspended loading robots 3 are symmetrically installed on both sides of the conveyor roller bed 2 to grab gears and load them onto the suspended loading heat treatment tray 1.

[0036] Visual inspection device 4 is installed on one side of the suspended loading robot 3 and is used to identify the suspension position of the suspended loading heat treatment tray 1.

[0037] The connecting bracket 5 is set below the vision inspection device 4 and corresponds to the suspended loading robot 3, and is used to place the gear to be loaded.

[0038] Robot control cabinet 6, the output end of robot control cabinet 6 is connected to the hanging loading robot 3, and is used to control the action of hanging loading robot 3;

[0039] The host computer 7 has its input end connected to the vision inspection device 4 and its output end connected to the robot control cabinet 6. It is used to transmit corresponding motion information to the robot control cabinet 6 based on the information from the vision inspection device 4.

[0040] Furthermore, in the gear-suspended carburizing and quenching robot fully automatic mounting workstation of this utility model, the suspended mounting heat treatment tray 1 includes a tooling base 11, a main suspension plate 12 and a suspension bracket 13. The main suspension plate 12 is fixed to the tooling base 11 by bolts, and the suspension bracket 13 is set on the main suspension plate 12.

[0041] Furthermore, in the fully automatic mounting workstation of the gear suspension carburizing and quenching robot of this utility model, both the tooling base 11 and the main suspension plate 12 adopt a hollow design, so that the stress can be effectively released through the hollow part during the quenching process, and the deformation caused by the stress after heating of the tooling base 11 and the main suspension plate 12 can be minimized. The main suspension plate 12 is provided with threaded mounting tables 121 arranged in both the horizontal and vertical directions. The suspension bracket 13 is threadedly engaged with the threaded mounting tables 121, thereby ensuring that multiple gears can be quenched at the same time.

[0042] Furthermore, in the gear-suspended carburizing and quenching robot fully automatic mounting workstation of this utility model, the suspension bracket 13 is arranged in a cross shape, which effectively improves the load-bearing capacity of the suspension bracket 13 and avoids deformation at high temperatures.

[0043] Furthermore, in the gear-suspended carburizing and quenching robot fully automatic clamping workstation of this utility model, the suspended clamping robot 3 includes a mounting base 31, a turntable 32, a robot arm 33, and a gripper 34. The turntable 32 is rotatably mounted on the mounting base 31, the robot arm 33 is mounted on the turntable 32, and the gripper 34 is mounted on the robot arm 33, thereby ensuring that the robot can perform multi-directional movements.

[0044] Furthermore, in the gear-suspended carburizing and quenching robot fully automatic clamping workstation of this utility model, one end of the arm 33 is connected to the turntable 32, and the other end of the arm 33 is provided with a connecting flange 331. The gripper 34 is connected to the arm through the connecting flange 331, so that the gripper 34 can be replaced with a matching gripper 34 according to the gripping weight or gear shape.

[0045] Furthermore, in the gear-suspended carburizing and quenching robot fully automatic loading workstation of this utility model, the gripper 34 adopts a pneumatic three-point centering gripper 34.

[0046] Specifically, during loading, the appropriate gripper 34 model is first selected according to the gear model, and connected to the robot arm 33 via the connecting flange 331. The torque of the suspended loading robot 3 is adjusted to the specified requirements, the path program is selected, and the suspended loading heat treatment tray 1 is assembled. The suspension bracket 13 is fixed sequentially via the threaded mounting table 121, and the assembled suspended loading heat treatment tray 1 is placed on the conveyor roller bed 2. After the infrared limit recognition on the side of the conveyor roller bed 2, the pneumatic clamping is activated to prevent accidents such as tipping over during loading. At this time, the suspended loading is controlled by the robot control cabinet 6. The card loading robot 3 operates according to the program of the host computer 7. During the loading process, the vision detection device 4 identifies the position of the gear on the connecting bracket 5. The gripper 34 lowers its three fingers to automatically clamp the part and center it. The gear is picked up from the connecting bracket 5 and lifted and rotated 90°. The vision detection device 4 identifies each suspension bracket 13. The rotating gear is inserted into the vertical suspension bracket 13. The loading robot 3 on both sides alternately inserts the parts to avoid uneven load during the suspension process. There is also a sequence requirement for inserting parts on one side. The parts are inserted in a spiral from the outside to the inside and from the bottom to the top. This process is repeated until all parts are loaded.

[0047] In summary, compared with the prior art, the gear-suspended carburizing and quenching robot fully automatic clamping workstation of this utility model has the following advantages and beneficial effects:

[0048] This invention enables automated gear mounting, effectively saving manpower and resources, reducing production costs, and improving safety during the mounting process. By using a suspended mounting heat treatment tray, the uniformity of quenching and cooling on both sides of the gear is effectively improved, preventing deformation.
