Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A multi-station grinding device with continuous loading and unloading includes a base 1, an electric rotary disk 2, a clamping mechanism 3, a rotating mechanism 4, a reversing mechanism 5, and a grinding mechanism 6.

[0033] An electric rotating disk 2 is fixedly installed on the upper end of the base 1;

[0034] Multiple sets of clamping mechanisms 3 for fixing workpieces are installed on the movable end of the electric rotary disk 2;

[0035] The front side of the base 1 is set as the loading and unloading station; the right side of the base 1 is set as the first grinding station; the left side of the base 1 is set as the second grinding station; and the rear side of the base 1 is set as the reversing station.

[0036] Both the first and second grinding stations are equipped with a grinding mechanism 6 for grinding the gear shaft workpiece body 7 and a rotating mechanism 4 for controlling the rotation of the clamping mechanism 3 to make the gear shaft workpiece body 7 rotate; and the rotating mechanism 4 is installed on the lower side of the base 1; the grinding mechanism 6 is installed on the upper end of the base 1.

[0037] A reversing mechanism 5 is installed at the reversing station to drive the workpiece to flip and change its surface; the reversing mechanism 5 is installed on the upper rear side of the base 1.

[0038] like Figure 1 As shown, the grinding mechanism 6 includes a linear module 61, a rotating assembly, and two sets of grinding assemblies; the linear module 61 is fixedly mounted on the upper end of the base 1 by a bracket; the movable end of the linear module 61 is equipped with a rotating assembly that drives the two sets of grinding assemblies to rotate; the grinding assemblies are mounted on the rotating assembly.

[0039] The upper side of the switching component is designated as the standby position; the lower side of the switching component is designated as the working position.

[0040] The upper and lower sides of the gear shaft workpiece body 7 are provided with clamping parts; the middle part of the gear shaft workpiece body 7 is provided with a grinding part.

[0041] In this utility model, the robot arm inserts the lower clamping part of the gear shaft workpiece body 7 to be ground into the clamping mechanism 3 of the loading and unloading station. Then, the clamping mechanism 3 works to clamp and fix the gear shaft workpiece body 7. Then, the electric rotary disk 2 works to drive the gear shaft workpiece body 7 to rotate to the first grinding station. At this time, the linear module 61 of the first grinding station works to drive the rotating component and the grinding component to move to the left until the grinding component in the working position contacts the outer side of the upper end surface of the grinding part of the gear shaft workpiece body 7. Then, the grinding component works to grind and deburr the upper end surface of the grinding part of the gear shaft workpiece body 7. At the same time, the rotating mechanism 4 of the first grinding station works to drive the clamping mechanism 3 in the first grinding station to rotate, so that the grinding component can grind the upper end surface of the grinding part of the gear shaft workpiece body 7 in all directions.

[0042] After the grinding operation of the upper end of the grinding part of the gear shaft workpiece body 7 is completed, the electric rotary table 2 drives the gear shaft workpiece body 7 to move to the reversing station. First, the reversing mechanism 5 fixes the gear shaft workpiece body 7, and the clamping mechanism 3 releases the fixation of the gear shaft workpiece body 7. Then, the reversing mechanism 5 drives the gear shaft workpiece body 7 to move upward, so that the lower clamping part of the gear shaft workpiece body 7 separates from the clamping mechanism 3. During the movement, the reversing mechanism 5 will also drive the gear shaft workpiece body 7 to rotate, so that the upper clamping part of the gear shaft workpiece body 7 rotates to the bottom. Then, the reversing mechanism 5 drives the gear shaft workpiece body 7 to return to its original position. Then, the clamping mechanism 3 fixes the upper clamping part of the gear shaft workpiece body 7, and at this time, the lower end face of the grinding part of the gear shaft workpiece body 7 faces upward.

[0043] Subsequently, the electric rotary table 2 drives the gear shaft workpiece body 7, which has completed the reversal, to move to the second grinding station. Similarly, the linear module 61, grinding components and rotating mechanism 4 of the second grinding station work to grind and deburr the lower end face of the grinding part of the gear shaft workpiece body 7.

[0044] Subsequently, the electric rotary table 2 drives the gear shaft workpiece body 7, which has completed the grinding operation, back to the loading and unloading station. Finally, the robot arm removes the gear shaft workpiece body 7. By repeating the above operation, continuous double-end grinding operation of the gear shaft workpiece body 7 can be achieved, avoiding the extra workload of manual intervention for flipping operation.

[0045] Furthermore, when the grinding components at the working position become worn, the rotation component drives the two sets of grinding components to rotate, causing the worn grinding components to rotate to the standby position. Then, the operator can replace or repair the worn grinding disc 67 without stopping the machine, further improving the grinding efficiency of the device.

[0047] like Figure 3 As shown, the rotating mechanism 4 includes a dual-axis cylinder 42, a lifting plate 43, a motor 44, a locking block 45, and a vertical limiting rod 46; a clearance groove 41 is provided on the upper side of the base 1; the dual-axis cylinder 42 is fixedly installed on the inner top of the base 1 through a supporting horizontal plate; the output end of the dual-axis cylinder 42 is fixedly connected to the outer side of the lower end of the lifting plate 43; the motor 44 is fixedly installed on the inner side of the lower end of the lifting plate 43; the locking block 45 is fixedly installed on the output end of the motor 44; the vertical limiting rod 46 is fixedly installed on the inner top of the base 1; the lifting plate 43 and the vertical limiting rod 46 are in a limited sliding connection.

[0048] The bottom end of the rotating shaft 34 is provided with a slot that engages with the locking block 45.

[0049] like Figure 3 and Figure 4As shown, the reversing mechanism 5 includes a frame 51, a push cylinder 52, a U-shaped vertical plate 53, a guide rail 54, a sliding block 55, a first rotary cylinder 56, and a pneumatic gripper 57. The frame 51 is fixedly installed on the upper rear side of the base 1; the push cylinder 52 is fixedly installed on the inner top end of the frame 51; the U-shaped vertical plate 53 is fixedly installed on the upper end of the frame 51; the guide rail 54 is symmetrically fixedly installed on the left and right sides of the front end of the U-shaped vertical plate 53; the sliding block 55 is limited and slidably connected to the left and right guide rails 54; the first rotary cylinder 56 is fixedly installed on the front end of the sliding block 55; the pneumatic gripper 57 is fixedly installed on the output end of the first rotary cylinder 56; and the output end of the push cylinder 52 is fixedly connected to the lower end of the sliding block 55.

[0050] like Figure 4 As shown, the switching assembly includes a second rotary cylinder 62, a rotating plate 63, and a fixed bait plate 64; the second rotary cylinder 62 is fixedly installed at the movable end of the linear module 61; the rotating plate 63 is fixedly installed at the output end of the second rotary cylinder 62; the fixed bait plate 64 is symmetrically fixedly installed on the upper and lower front ends of the rotating plate 63; the fixed bait plate 64 is connected to the grinding assembly.

[0051] The grinding assembly includes a drive motor 65, a rotating rod 66, and a grinding disc 67; the drive motor 65 is fixedly installed at one end of the two fixed bait plates 64 that are close to each other; the rotating rod 66 is rotatably installed at one end of the two fixed bait plates 64 that are far apart from each other; the output end of the drive motor 65 is fixedly connected to the rotating rod 66; the grinding disc 67 is detachably connected to the rotating rod 66 by fasteners.

[0052] The fastener may be a bolt;

[0053] In this invention, a robotic arm inserts the lower clamping part of the gear shaft workpiece body 7 to be ground between the movable ends of the pneumatic three-jaw chuck 33 at the loading / unloading station. The pneumatic three-jaw chuck 33 then clamps and fixes the gear shaft workpiece body 7. Subsequently, the electric rotary disk 2 rotates the gear shaft workpiece body 7 to the first grinding station. At this time, the linear module 61 of the first grinding station moves the first rotary cylinder 56 to the left until the lower end of the grinding disc 67 in the working position contacts the outer side of the upper surface of the grinding part of the gear shaft workpiece body 7. Then, the drive motor 65 in the working position drives the rotating rod 66 to rotate, causing the grinding disc 67 to rotate along with the rotating rod 66 to perform grinding and deburring operations on the upper surface of the grinding part of the gear shaft workpiece body 7.

[0054] At the same time, the dual-axis cylinder 42 of the first grinding station works to push the lifting plate 43 upward, so that the lifting plate 43 drives the motor 44 and the clamping block 45 to move upward along the vertical limit rod 46 until the clamping block 45 engages with the groove opened at the lower end of the rotating shaft 34; then the motor 44 works to drive the clamping block 45 to rotate, and the rotation of the clamping block 45 will drive the rotating shaft 34 to rotate, so that the pneumatic three-jaw chuck 33 rotates with the rotating shaft 34, so that the grinding disc 67 can perform all-round grinding on the upper surface of the grinding part of the gear shaft workpiece body 7;

[0055] After the grinding operation of the upper end of the grinding part of the gear shaft workpiece body 7 is completed, the electric rotary disk 2 drives the gear shaft workpiece body 7 to move to the reversing station; then the push cylinder 52 works to pull the sliding block 55 along the guide rail 54 to drive the first rotary cylinder 56 and the pneumatic gripper 57 to move downward until the pneumatic gripper 57 is flush with the grinding part of the gear shaft workpiece body 7. Then the pneumatic gripper 57 works to clamp and fix the outer end of the grinding part of the gear shaft workpiece body 7. Then the pneumatic three-jaw chuck 33 releases the fixation of the gear shaft workpiece body 7.

[0056] Subsequently, the push cylinder 52 operates to drive the gear shaft workpiece body 7 to reset upward, causing the lower clamping part of the gear shaft workpiece body 7 to separate from the pneumatic three-jaw chuck 33. During the movement, the first rotary cylinder 56 will also drive the pneumatic jaw 57 to rotate, causing the upper clamping part of the gear shaft workpiece body 7 to rotate downward. Then, the push cylinder 52 operates to drive the gear shaft workpiece body 7 to move downward. Subsequently, the pneumatic three-jaw chuck 33 operates to fix the upper clamping part of the gear shaft workpiece body 7, and at this time, the lower end face of the grinding part of the gear shaft workpiece body 7 faces upward.

[0057] Subsequently, the electric rotary table 2 drives the gear shaft workpiece body 7, which has completed the reversal, to move to the second grinding station. Similarly, the linear module 61, grinding disc 67 and clamping block 45 of the second grinding station work together to grind and deburr the lower end face of the grinding part of the gear shaft workpiece body 7.

[0058] Subsequently, the electric rotary table 2 drives the gear shaft workpiece body 7, which has completed the grinding operation, back to the loading and unloading station. Finally, the robot arm removes the gear shaft workpiece body 7. By repeating the above operation, continuous double-end grinding operation of the gear shaft workpiece body 7 can be achieved.

[0059] Furthermore, when the grinding disc 67 in the working position becomes worn, the drive motor 65 drives the rotating rod 66 to rotate, causing the worn grinding disc 67 to rotate to the standby position. Then, the operator can replace or repair the worn grinding disc 67 without stopping the machine.
