Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, specifically to a rigid chain loading and unloading robot. Background Technology

[0002] A CNC lathe is a high-precision, high-efficiency automated lathe that uses digital code to control the movement of the cutting tool, enabling the precision machining of complex parts. Robotic arms can automate the lathe machining process, replacing manual labor in loading and unloading operations, reducing human intervention, shortening lathe downtime, and enabling continuous production.

[0003] In the use of existing rigid chain loading and unloading robots, with the advancement of CNC lathes, especially the widespread use of high-speed cutting technology, in order to prevent the splashing of cutting fluid and metal chips and to facilitate their collection, lathes are often designed as enclosed structures, especially the front, back and top surfaces in the direction of rotation. Enclosed lathes can only load and unload parts by opening and closing the front protective door, and loading and unloading cannot be done synchronously, resulting in long waiting times for the lathe and thus reducing processing efficiency. In addition, due to design reasons, the robot usually has a large fixed volume, which occupies a large amount of internal height space of the lathe when loading and unloading parts. This may cause its movement trajectory to interfere with the lathe spindle, tool post and other components, affecting processing accuracy or causing collision accidents. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 As shown, the rigid chain lifting and lowering robot includes a support frame 1, the bottom of which is fixed to the ground to support the robot structure; a guide rail 2 is fixedly connected to the top of the support frame 1, and a lathe 3 is arranged on the outer side away from the guide rail 2. The guide rail 2 passes laterally through the interior of the lathe 3. The lathe 3 is used to process rotating parts, and the cutting operation is completed by the linear movement of the workpiece and the tool. This is existing technology and will not be described in detail here; an auxiliary component 5 is arranged on the outer side of the lathe 3; two sets of movable seats 4 slide on the outer side of the guide rail 2 to support the various components of the robot; two sets of conveying components 6 are mirrored on the outer side of the guide rail 2 to move the movable seats 4.

[0027] The drive assembly 7 is respectively located on the outside of the two sets of movable seats 4. A chain 8 is provided on the outside of the drive assembly 7. The chain structure is specially designed to withstand push and pull forces and has high rigidity, high precision and durability. The lifting or pushing and pulling action is achieved through linear telescopic movement. A connecting frame 9 is fixedly connected to one end of the chain 8. The guide assembly 10 is mirror-located on the outside of the movable seat 4 and the connecting frame 9, and there are two sets. A stabilizing assembly 11 is provided on the outside of both sets of guide assemblies 10. The power assembly 12 is located on the outside of the connecting frame 9 and consists of a motor and a synchronous conveyor belt. The electric synchronous conveyor belt rotates to transmit power. A clamping assembly 13 for fixing the workpiece is provided on the outside of the motor drive power assembly 12.

[0028] The auxiliary component 5 includes a protective door 51 that rotates on the outside of the lathe 3. Two parting ports 52 are opened on the outside of the lathe 3. The protective door 51 can provide physical isolation during equipment operation or maintenance to prevent personnel from accidentally touching the cutting tools or mechanical parts and avoid operational risks. Two robotic arms can enter and exit the lathe 3 through the parting ports 52, which facilitates the simultaneous loading and unloading of parts by the two sets of robotic arms.

[0029] The conveying assembly 6 includes a first motor 61 located at one end of the guide rail 2. The output end of the first motor 61 is equipped with a synchronous belt 62. Multiple pulleys 63 are rotatably connected to the inner side of the movable seat 4. The outer side of the pulleys 63 is slidably connected to the outer side of the guide rail 2. The first motor 61 transmits power to the movable seat 4 through the synchronous belt 62, so that the robot moves along the guide rail 2 to load and unload parts. The design of the pulleys 63 ensures that the movable seat 4 slides smoothly on the guide rail 2.

[0030] The drive assembly 7 includes a storage box 73 fixed to the bottom of the movable base 4. A second motor 71, which is a servo motor, is provided on the outside of the storage box 73. It can precisely control the speed and torque. A sprocket 72 is provided at the output end of the second motor 71. A chain 8 is meshed on the outside of the sprocket 72. When the second motor 71 drives the sprocket 72 to rotate, the sprocket 72 meshes with the chain links of the chain 8 through its teeth, which causes the chain 8 to extend or retract from the storage box 73. A guide mechanism is provided inside the storage box 73 to guide the movement of the chain 8, while also accommodating the chain 8 and protecting it from the influence of the external environment.

[0031] The guide assembly 10 includes a guide rail 101 fixed to the top of the connecting frame 9. A slide block 102 is slidably connected to the top of the guide rail 101. Another set of mirror-arranged guide rails 101 is fixed to the bottom of the movable seat 4. The slide block 102 can slide along the outside of the guide rail 101 under the drive of external force. The guide rail 101 can limit the movement path of the slide block 102 and improve the stability of the slide block 102.

[0032] The stabilizing component 11 includes a first rotating rod 111 that rotates on the top of the connecting frame 9. A second rotating rod 112 is rotatably connected to the outer side of the slide 102. The outer sides of the first rotating rod 111 and the second rotating rod 112 are rotatably connected. One end of the first rotating rod 111 rotates to the bottom of the movable seat 4, and the other end is rotatably connected to the mirror-image first rotating rod 111. The other end of the mirror-image first rotating rod 111 is rotatably connected to the top of the connecting frame 9. The connection method of the second rotating rod 112 is similar. The two second rotating rods 112 are rotatably connected to their respective slides 102. The stabilizing component 11 is similar to the scissor lift structure and is used to improve the stability of the connecting frame 9 when it is raised or lowered.

[0033] The clamping assembly 13 includes a clamping block 131 disposed on the outside of the power assembly 12. A limit frame 132 is fixedly connected to the outside of the connecting frame 9, and a set of immovable clamping blocks 131 is fixed at one end of the limit frame 9. The workpiece is clamped by the cooperation of the two sets of clamping blocks 131. The inner side of the limit frame 132 is slidably connected to the outer side of the clamping block 131. The clamping block 131 is fixed on the outside of the synchronous conveyor belt disposed on the power assembly 12 for fixing the workpiece and loading and unloading the workpiece. The limit frame 132 is used to limit the movement path of the clamping block 131, so that it moves according to a predetermined route trajectory, thereby improving the stability of the clamping block 131.

[0034] Working principle: In use, after the workpiece is processed, the robot responsible for unloading first grabs the workpiece through the clamping component 13, and then drives it through the conveying component 6 to leave the lathe 3 through the outlet 52, completing the unloading. At the same time, the first motor 61 drives the synchronous belt 62 to rotate, driving the moving seat 4 to move along the guide rail 2. As it moves, it enters the lathe 3 through the outlet 52. After reaching the designated position, the second motor 71 drives the sprocket 72 to rotate, and the sprocket 72 drives the chain 8 to extend from the storage box 73. At this time, the chain 8 is extended in a columnar shape, carrying the connecting frame 9 downward. As the height of the connecting frame 9 changes, one end of the second rotating rod 112 moves along the guide rail 101 through the slide 102. At this time, the first rotating rod 111 and the second rotating rod 112 rotate and unfold, changing the connection angle and improving the stability of the connecting frame 9 during the lifting process. Then, the power component 12 drives the clamping block 131 to move, and after the workpiece is put down, the loading is completed.
