Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, and particularly relates to a manipulator for mechanical manufacturing. Background Art

[0002] Mechanical manufacturing refers to the industrial department engaged in the production of various power machinery, hoisting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment. The production process of products refers to the whole process of turning raw materials into finished products. The production process of mechanical products includes the manufacture of blanks such as casting, the machining of parts such as cutting, heat treatment, surface treatment, etc., the assembly of products such as general assembly, sub-assembly, commissioning inspection and painting. In mechanical manufacturing, the grasping and transferring of workpieces by manipulators effectively facilitate the processing of workpieces, and manipulators play an important role in mechanical manufacturing.

[0003] The prior art has the following deficiencies: In the prior art, the application number is 202321547306.X, which proposes a manipulator for mechanical manufacturing, including a first transmission body. A first motor is installed on the outer wall of one side of the first transmission body. The top of the first transmission body is slidably connected with a second transmission body. A belt transmission box is arranged on the outer wall of one side of the second transmission body. A second motor is installed on the outer wall of the belt transmission box above the second transmission body. One side of the surface of the second transmission body is slidably connected with a third transmission body. A third motor is installed at the top of the third transmission body. The surface of the third transmission body is slidably connected with a bearing frame. A cross plate is arranged at the bottom end of the bearing frame. Side plates are arranged on both sides of the bottom end of the cross plate. A linkage shaft is rotatably connected to the inner wall of one end of the side plate away from the cross plate. The utility model can not only perform clamping operations on obliquely placed objects to ensure the clamping effect of the manipulator on objects during use, but also facilitate the clamping of objects at different positions, and achieves the purpose of quickly clamping objects.

[0004] When the above equipment is in use, two groups of chucks rotate towards each other to clamp and release objects. When clamping an object, only the clamping force of the two groups of chucks is used to clamp the side of the object. During the clamping process, if the clamped object is heavy and its surface is smooth, it is easy for the clamped object to fall due to external forces or the shaking of the robotic arm. At the same time, after the clamping mechanism has been used for a long time, in order to ensure the clamping stability, it is necessary to regularly overhaul and tighten the chucks to ensure the clamping effect. The overhaul process consumes manpower and increases the overhaul task of the manipulator. Summary of the Utility Model

[0036] Specifically, the lifting of the clamping mechanism 7 can be controlled by the electric telescopic rod 8.

[0037] In this embodiment, two connecting members 706 are fixedly mounted on the driving assembly 705. The cylinder 702 is fixedly mounted on the main frame 701 and its output end is fixed between the connecting members 706 through a pin. There are two connecting pieces 704 which are located within the slotted groove 703. The side of the connecting piece 704 is inclined. The connecting piece 704 and the jaw 708 are integrally formed. A driving assembly 705 is disposed between the two connecting pieces 704. Trapezoidal components adapted to the trapezoidal groove 707 are provided on both sides of the driving assembly 705.

[0038] Specifically, the connecting member 706 facilitates the connection between the output end of the air cylinder 702 and the driving assembly 705. Through the connecting member 704 and the trapezoidal groove 707, the clamping jaws 708 can approach or separate when the driving assembly 705 rises or falls.

[0039] In this embodiment, the bolt 7081 extends into the opening 7082 from the outside of the clamping jaw 708 and is rotatably connected to the inner wall of the opening 7082. A set of nuts is sleeved on and threadedly connected to the bolt 7081. A tooth groove adapted to the tooth 7085 is provided at the outer end of the bolt 7081 corresponding to the position of the opening 7082.

[0040] Specifically, the extension and retraction of the extension mechanism 7083 can be controlled by the bolt 7081. The opening 7082 facilitates the installation of the extension mechanism 7083. The tooth 7085 can be adapted to the tooth groove on the bolt 7081 to form a meshing.

[0041] In this embodiment, the extension mechanism 7083 is adapted to the opening 7082. The bolt 7081 passes through the through port 7084 and meshes with the tooth 7085. The bearing member 7086 is fixedly installed at the bottom end of the extension mechanism 7083. The structures of the two clamping jaws 708 are the same.

[0042] The object to be clamped can be carried by the bearing member 7086, further improving the stability of the clamping jaws 708 for clamping the object.

[0043] The working principle and usage process of the present utility model: During actual use, the device is placed in a suitable position and connected to an external power supply. The motor in the base 1 can be driven by the control device 9 to drive the rotation shaft 2 to rotate, thereby driving the swing arm 3 to swing to adjust the position. Then, the motor 5 can drive the threaded rod in the swing arm 3, thereby driving the extension arm 6 to move on the swing arm 3, thereby adjusting the extension position of the clamping mechanism 7 at the end of the extension arm 6.

[0044] When it is necessary to clamp an object, the swing arm 3 and the extension arm 6 can be adjusted in the above manner so that the clamping mechanism 7 corresponds to the object to be clamped. The air cylinder 702 drives the driving assembly 705 to descend and squeeze the two connecting members 704, so that the corresponding two clamping jaws 708 move away from each other to the two sides. The electric telescopic rod 8 can drive the entire clamping mechanism 7 to descend to cover the two clamping jaws 708 corresponding to the object to be clamped. Then, the air cylinder 702 lifts the driving assembly 705 to rise, causing the two connecting members 704 to approach each other, driving the two clamping jaws 708 to clamp the corresponding object.

[0045] Finally, the clamping mechanism 7 is lifted by the electric telescopic rod 8, and the direction is transferred through the swing arm 3 and the extension arm 6 to achieve the effect of transferring the object. Before clamping the object, the carrier 7086 can be extended outward according to the height of the object. The extension mechanism 7083 is controlled to extend out of or retract into the opening 7082 by turning the bolt 7081 to adjust the extension distance of the carrier 7086. After the adjustment is completed, the nut on the bolt 7081 is tightened in the direction of the side of the jaw 708 to keep the extension mechanism 7083 stable. When clamping the object, the carrier 7086 is in contact with the horizontal plane where the object to be clamped is placed. When the jaws 708 approach each other, the carrier 7086 can scoop up the object, and then the object is clamped by the jaws 708, while the carrier 7086 will support the clamped object at the bottom, which can further ensure the stability of the robotic arm when clamping the object and prevent the clamped object from falling;

[0046] At the same time, the jaws 708 are stably installed by the trapezoidal groove 707 and the trapezoidal components on both sides of the drive assembly 705. The jaws 708 avoid the use of redundant screws and pins, prevent loosening caused by long-term use, reduce the frequency of maintenance and repair, and reduce the burden on maintenance personnel.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
