Description

Technical Field

[0001] This invention relates to the field of disc-shaped workpiece processing technology, and more specifically to a disc-shaped workpiece gripping and pushing device. Background Technology

[0002] In the machining field, when loading disc-shaped workpieces, finger cylinders with pneumatic grippers are usually used to pick up the disc-shaped workpieces from the material rack and place them in the lathe chuck, so that the disc surface of the workpiece is in close contact with the lathe chuck.

[0003] In the prior art, in order to ensure that the end face of the disc-shaped workpiece is tightly attached to the lathe chuck, a pushing mechanism is usually installed on the three-jaw cylinder. During loading, after the disc-shaped workpiece is gripped into the lathe chuck, the cylinder is released, and the pushing mechanism pushes the disc-shaped workpiece until it is tightly attached to the lathe chuck, thereby ensuring that the disc-shaped workpiece is loaded in place.

[0004] For example, Chinese patent CN207327025U discloses an elastic pushing and centering gripper mechanism, including a flange for connecting to a robot, a three-jaw cylinder with grippers connected to the flange, and an elastic pushing assembly disposed on the three-jaw cylinder. The elastic pushing assembly includes an elastic element disposed on the three-jaw cylinder and a positioning block connected to the elastic element. The elastic element includes a guide rod and a spring sleeved on the guide rod. One end of the guide rod is sleeved on the fixing block, and the other end of the guide rod is connected to the positioning block.

[0005] The elastic pushing component (i.e., the pushing mechanism) of the aforementioned pushing and centering gripper mechanism includes guide rods, springs, fixing blocks, and positioning blocks, among other components. It has numerous parts, a highly complex structure, and high manufacturing costs. Furthermore, occasionally, machining debris may become stuck, causing the positioning block to fail to spring back into place, ultimately resulting in the disc-shaped workpiece not being properly aligned. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a disc-shaped workpiece gripping and pushing device, which simplifies the structure, reduces costs, and improves stability while ensuring that the disc-shaped workpiece is pushed into place.

[0007] To achieve the above objectives, the present invention provides a disc-shaped workpiece gripping and pushing device, including a finger cylinder, wherein the finger cylinder is provided with at least three pneumatic grippers for gripping disc-shaped workpieces.

[0008] The pneumatic gripper includes a mounting plate and a clamping plate, wherein the mounting plate is connected to the movable seat of the finger cylinder, and the clamping plate is vertically disposed at the end of the mounting plate away from the finger cylinder;

[0009] A pusher elastic element is fixedly provided on the mounting plate. The free end of the pusher elastic element is used to abut against the disc-shaped workpiece. The pusher elastic element can rebound and release energy to push the disc-shaped workpiece.

[0010] Preferably, the pusher elastic element is a folding spring sheet;

[0011] One end of the folding spring sheet is integrally connected to the mounting plate of the pneumatic gripper, and the other end of the folding spring sheet is used to abut against the corresponding disc surface of the disc-shaped workpiece.

[0012] Preferably, the free end of the folded spring sheet has a pressing surface that mates with the disc surface of the disc-like workpiece.

[0013] Preferably, the pressing surfaces of all the folded spring sheets are flush.

[0014] Preferably, the number of pneumatic grippers provided on the finger cylinder is three.

[0015] The present invention has the following beneficial effects:

[0016] In practical applications, the finger cylinder is connected to the robotic arm, which drives the finger cylinder to move at the target position. During the loading process, firstly, the gripper opens outward, and the robotic arm aligns the gripper with the disc-shaped workpiece; then, it moves the gripper downward so that the pushing elastic element on the gripper contacts the corresponding disc surface of the workpiece; then, the robotic arm continues to move the gripper downward, compressing the pushing elastic element; after the pushing elastic element is compressed to a predetermined position, the gripper closes, thus clamping the disc-shaped workpiece; next, the robotic arm moves the gripper to transport the disc-shaped workpiece to the lathe chuck and releases the gripper, causing the compressed pushing elastic element to rebound and release energy to push the disc-shaped workpiece tightly against the lathe chuck, thereby ensuring that the disc-shaped workpiece is loaded in place. Therefore, the above-mentioned disc-shaped workpiece gripping and pushing device uses a pushing elastic element that replaces the traditional, unreliable, and highly complex pushing mechanism. It has a simple structure, good stability, and is easy to operate, effectively pushing the disc-shaped workpiece tightly against the lathe chuck, ensuring proper loading and improving the processing qualification rate.

[0026] The core of this invention is to provide a device for gripping and pushing disc-shaped workpieces, which simplifies the structure, reduces costs, and improves stability while ensuring that the disc-shaped workpieces are pushed into place.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1 The figure shown is a three-dimensional structural schematic diagram of the disc-shaped workpiece gripping and pushing device provided in an embodiment of the present invention, as follows: Figure 2 The figure shown is a cross-sectional view of the disc-shaped workpiece gripping and pushing device provided in an embodiment of the present invention. Figure 3 The diagram shown is a schematic diagram of the assembly structure of the pneumatic gripper 3 and the pusher elastic element 4 provided in an embodiment of the present invention.

[0029] This invention discloses a device for gripping and pushing disc-shaped workpieces, including a finger cylinder 1. The finger cylinder 1 is equipped with at least three grippers 3 for gripping disc-shaped workpieces 2. Each gripper 3 includes a mounting plate 31 and a clamping plate 32. The mounting plate 31 is connected to the movable seat of the finger cylinder 1, and the clamping plate 32 is vertically disposed at the end of the mounting plate 31 away from the finger cylinder 1. The number of grippers 3 can be three, four, or other numbers. Technicians can adapt the selection based on the weight and dimensions of the disc-shaped workpiece 2. The specific number of grippers 3 is not specifically limited here.

[0030] A pusher elastic element 4 is fixedly installed on the mounting plate 31. The free end of the pusher elastic element 4 is used to abut against the disc-shaped workpiece 2. The pusher elastic element 4 can rebound and release energy to push the disc-shaped workpiece 2.

[0031] In practical applications, the finger cylinder 1 is connected to the robotic arm, which drives the finger cylinder 1 to move at the target position. During the loading process, firstly, the gripper 3 opens outward, and the robotic arm aligns the gripper 3 with the disc-shaped workpiece 2; then, it moves the gripper 3 downward so that the pushing elastic element 4 on the gripper 3 contacts the corresponding disc surface of the disc-shaped workpiece 2; then, the robotic arm continues to move the gripper 3 downward, and the pushing elastic element 4 is compressed; after the pushing elastic element 4 is compressed to the predetermined position, the gripper 3 closes, thus completing the clamping of the disc-shaped workpiece 2; then, the robotic arm drives the gripper 3 to transport the disc-shaped workpiece 2 to the lathe chuck and releases the gripper 3, and the compressed pushing elastic element 4 rebounds and releases energy to push the disc-shaped workpiece 2 tightly against the lathe chuck, thereby ensuring that the disc-shaped workpiece is loaded in place. It can be seen that the above-mentioned disc-shaped workpiece gripping and pushing device replaces the traditional pushing mechanism with poor reliability and very complex structure with its pushing elastic element 4. It has a simple structure, good stability, and is easy to operate. It can push the disc-shaped workpiece 2 to be in close contact with the lathe chuck, ensuring that the workpiece is loaded in place and improving the processing qualification rate.

[0032] In some specific implementation schemes, in order to improve the strength of the pusher elastic element 4 and increase its service life, such as... Figure 3 As shown, the pusher elastic element 4 can be designed as a folding spring sheet. One end of the folding spring sheet is integrally connected to the mounting plate 31 of the pneumatic gripper 3, and the other end of the folding spring sheet is used to abut against the corresponding disc surface of the disc-shaped workpiece 2. The pusher elastic element 4 adopts a folding spring sheet, which has high strength and resilience, and can ensure the stability when pushing the disc-shaped workpiece 2.

[0033] Furthermore, the free end of the folding spring sheet has a pressing surface 41 that mates with the corresponding disc surface of the disc-type workpiece 2 (see...). Figure 3 In this way, the pressing surface 41 of the folded spring sheet 4 matches the corresponding disc surface of the disc-shaped workpiece 2, resulting in a larger contact area between the folded spring sheet and the disc-shaped workpiece 2, more stable pressure, and further improved pressing stability. Advantageously, the pressing surfaces 4 of all folded spring sheets 4 can be designed to be flush, allowing for the application of uniform pressing force to the disc-shaped workpiece 2, further improving pressing stability.
