Description

Technical Field

[0001] This utility model mainly relates to the field of industrial robotic arms, specifically an intelligent clamping robotic arm for machine processing. Background Technology

[0002] In the field of mechanical manufacturing, shaft parts, as basic components, are widely used in industries such as automobiles, aerospace, and medical devices. Their machining process typically involves multiple steps, including turning, grinding, and drilling, requiring frequent transfers between different machining stations. During this process, the stability, flexibility, and degree of automation of the clamping robot directly affect the machining accuracy and production efficiency of the parts.

[0003] In the existing technology, clamping devices used for machining shaft parts generally have the following shortcomings: First, traditional clamping mechanisms mostly adopt rigid connections and rely on cylinders or hydraulic cylinders for driving. They are complex in structure and large in size, making it difficult to adapt to the needs of flexible movement. Second, they have poor compatibility with shaft parts of different specifications. When there are differences in the diameter of the parts, traditional clamping devices cannot adjust the clamping force through structural self-adaptation. They need to frequently change fixtures or recalibrate, which increases the production preparation time. Utility Model Content

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A smart clamping robot for machine processing includes a support frame, a fixed plate hinged to the top of the support frame, and mounting frames symmetrically fixed to the bottom of the support frame. Each mounting frame has a gripper symmetrically hinged to its bottom. Two mounting frames are hinged to each other, and the connecting blocks are driven to the corresponding grippers. The two connecting blocks are fixedly connected to each other by a connecting plate. A fixing rod is fixedly installed on the top of the connecting plate and fixedly connected to the bottom of the fixing plate.

[0006] The support frame is hinged to the four corners of the top, with a first connecting rod at the other end of each first connecting rod and a second connecting rod at the other end. Each second connecting rod is hinged to the fixed plate.

[0007] The mounting bracket has symmetrically hinged transmission blocks inside, with two transmission blocks hinged to the bottom of corresponding connecting blocks. The bottom of each transmission block is hinged to a corresponding gripper. A transmission rod is symmetrically hinged to the side of the mounting bracket near the bottom, and the transmission rod is hinged to a corresponding gripper.

[0008] Compared with the existing technology, the beneficial effects of this utility model are:

[0009] This utility model has a simple structure, is easy to install and use, and adopts a hinged linkage design, eliminating the need for additional drive devices such as cylinders or hydraulic cylinders. The overall structure is simple and compact, lightweight and small in size. The lifting of the robotic arm directly drives the opening and closing of the gripper, eliminating the need for an independent control system. The clamping and releasing actions are completely synchronized with the movement of the robotic arm, avoiding positioning deviations and improving the positioning consistency of multi-station processing. It can adapt to various shaft parts without changing the fixtures, and the pure mechanical transmission helps to reduce energy consumption and maintenance costs. Attached Figure Description

[0015] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0016] Referring to the accompanying drawings, an intelligent clamping robot for machine processing includes a support frame 1. A fixed plate 2 is hinged to the top of the support frame 1. The top of the fixed plate 2 is fixedly connected to an external robotic arm, which moves the device to a suitable position. Mounting frames 3 are symmetrically fixedly arranged at the bottom of the support frame 1. Each mounting frame 3 has a gripper 4 symmetrically hinged to its bottom. Two mounting frames 3 are internally hinged to connecting blocks 5. The connecting blocks 5 are drively connected to the corresponding gripper 4. The two connecting blocks 5 are fixedly connected to each other through a connecting plate 6. A fixing rod 7 is fixedly arranged at the top of the connecting plate 6. The fixing rod 7 is fixedly connected to the bottom of the fixed plate 2.

[0017] The support frame 1 is hinged to the four corners of the top with first connecting rods 8, and the other end of each first connecting rod 8 is hinged to a second connecting rod 9. Each second connecting rod 9 is hinged to the fixed plate 2. When the external robotic arm lifts the fixed plate 2, it drives the fixed rod 7 to move upward.

[0018] The mounting bracket 3 has symmetrically hinged transmission blocks 10 inside, and the two transmission blocks 10 are hinged to the bottom of the corresponding connecting blocks 5. The bottom of the transmission blocks 10 is hinged to the corresponding grippers 4. The side of the mounting bracket 3 is symmetrically hinged to the bottom of the transmission rods 11, and the transmission rods 11 are hinged to the corresponding grippers 4. The two grippers 4 are closed and clamped by the upward movement of the connecting blocks 5.

[0019] When this device is in use, the external robotic arm is fixedly connected to the top of the fixed plate 2. The device is moved to the middle position of the shaft part, and the device is moved downward so that the part is located in the two sets of grippers 4. The external robotic arm lifts the fixed plate 2 upward. When the fixed plate 2 moves upward, the connecting plate 6 is also moved upward through the fixed rod 7, which in turn drives the connecting block 5 to move upward, causing the grippers 4 to close. Finally, the two sets of grippers 4 complete the clamping and fixing of the shaft part.

[0020] After the gripper 4 clamps the workpiece, the external robotic arm can move the entire device to different processing positions according to the processing requirements. The external robotic arm moves the fixed plate 2 downward, and the fixed rod 7 moves downward with the fixed plate 2, which drives the connecting plate 6 and the connecting block 5 to move downward inside the mounting frame 3. When the connecting block 5 moves downward, the upper end of the transmission block 10 is driven downward, which causes the transmission block 10 to push the gripper 4 to rotate outward around the hinge point at the bottom of the mounting frame 3. At the same time, the transmission rod 11 also swings in the opposite direction to assist the gripper 4 in opening and releasing the processed shaft parts.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
