Description

Technical Field

[0001] The present invention belongs to the technical field of machining and automation equipment, and particularly relates to a working device of a new type of cylindrical clamping machine. Background Art

[0002] A cylindrical clamping machine is mainly used in industrial handling, machining, and automated production processes, and can achieve clamping, rotation, and transfer of workpieces, etc. This equipment is widely used in industries such as 3C, automotive, medical, and new energy. In machining, a cylindrical clamping machine is used to hold and fix workpieces to meet the multi-angle machining requirements. In automated production, a cylindrical clamping machine can achieve rapid transfer and rotation of workpieces, improving production efficiency. The structure of the working device of a cylindrical clamping machine directly affects its operating efficiency and service life. During the working process, the working device may have insufficient rigidity, directly affecting its load-bearing capacity, which will greatly reduce the operating efficiency. Therefore, the design of the working device of a cylindrical clamping machine must meet the structural and usage requirements. The working conditions of a cylindrical clamping machine mainly cover horizontal clamping of cylinders, flipping of the clamping device, rotation of the clamping device, lifting of the boom, lateral movement of materials (cylinder transportation), and placement of materials (cylinder unloading), etc. Currently, the widely used cylindrical clamping machines mainly have the drawback of insufficient load-bearing capacity for rotary clamping. In order to adapt to the mining environment and improve the load-bearing capacity of the working device, it is very necessary to research and design a new type of high-performance cylindrical clamping machine. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the present invention provides a new type of cylindrical clamping machine with high load-bearing capacity, wide working vision for operators, and stable and compact structure.

[0004] In order to solve the problems existing in the existing technology, the present invention adopts the following technical solutions: A working device of a new type of cylindrical clamping machine mainly includes a frame, a boom, a lifting hydraulic cylinder, a clamping device, a first rocker arm, a second rocker arm, a tilting hydraulic cylinder, a first connecting rod, and a second connecting rod. The two ends of the boom are respectively hinged to the frame and the clamping device; the two ends of the lifting hydraulic cylinder are respectively hinged to the frame and the boom; the cylinder barrel end of the tilting hydraulic cylinder is hinged to the first rocker arm and the second rocker arm to form a compound hinge. The two ends of the first connecting rod are respectively hinged to the piston rod end of the tilting hydraulic cylinder and the frame; the two ends of the second connecting rod are respectively hinged to the frame and the middle part of the first connecting rod. The rear end of the first rocker arm is hinged to the frame, and the front end of the second rocker arm is hinged to the clamping device.

[0005] The advantages and positive effects brought by the device provided by the present invention:

[0006] 1. The working device of this machine adopts the form of a center-mounted tilting hydraulic cylinder. This structure can make the overall center of gravity of the cylindrical clamping machine more reasonably distributed, reduce the height of the center of gravity, and improve the stability during operation. The center-mounted tilting hydraulic cylinder makes the power transmission more balanced.

[0007] 2. The working device is of a symmetric structure, making the forces on both sides of the cylindrical clamping machine more balanced, improving the stability and safety of the whole machine. The symmetric mechanism design can better disperse the working load, reduce local stress concentration, and thus improve the structural strength and service life of the working device.

[0008] 3. It avoids the direct connection between the boom and the tilting hydraulic cylinder. With a relatively small driving force output by the hydraulic cylinder, a large movement range of the clamping device can be achieved, reducing energy consumption.

[0009] 4. The cylinder barrel end of the tilting hydraulic cylinder is hinged to the first rocker arm and the second rocker arm to form a compound hinge, which can enhance the structural strength of the working device of the cylindrical clamping machine and enable it to withstand a greater working load.

[0010] 5. The first connecting rod, the second connecting rod and the tilting hydraulic cylinder are arranged at a low position, making the overall structure more compact. At the same time, it effectively increases the operating vision of the cylindrical clamping machine, improves the phenomenon that the working device of the existing cylindrical clamping machine blocks the operator's working vision, and is easy to realize the real-time control of the cylindrical clamping machine.

[0011] 6. The working device of this machine has good translatability, and the clamping device can maintain horizontal movement during the lifting process of the boom.

[0012] 7. At the front end of the working device, i.e., the cylinder end of the tilting hydraulic cylinder is hinged to the first rocker arm and the second rocker arm to form a compound hinge. At the rear end of the working device, i.e., the connection of the first connecting rod, the tilting hydraulic cylinder and the second connecting rod does not adopt a compound hinge. The reasons for using a single hinge instead of a compound hinge here and the advantages of the single hinge are as follows: At this part of the cylindrical gripper, using a compound hinge will increase unnecessary structural complexity, and a single hinge can meet the basic rotational function requirements; the motion requirements of the cylindrical gripper at this place are relatively single, mainly realizing rotation within a certain angle range. The single hinge can ensure relatively stable motion transmission, avoiding problems such as motion interference and wear that may occur due to the connection of multiple components in the compound hinge; the single hinge structure is simple. During the force transmission process, compared with the compound hinge, it reduces the friction loss and force dispersion caused by the connection of multiple components and relative motion, enabling the gripper to act on the target object more efficiently when grasping and transporting the cylinder; the friction of the single hinge structure is small, and the heat energy loss caused by friction during the motion process is small. Using a single hinge can reduce the additional energy consumption and improve the energy utilization efficiency; the main requirement for this part of the cylindrical gripper is the rotational freedom in a single direction, and a single hinge can meet it. Adopting a multi-degree-of-freedom multi-hinge structure will greatly increase the complexity of the mechanical mechanism; the single hinge structure is simple and more concise in spatial layout. In the limited space of the gripper, the single hinge can achieve the function with a small space occupation, which helps to make the overall structure layout more compact and make the gripper structure design more reasonable.

Specific embodiments

[0022] In order to better explain the present invention for easy understanding, the technical solutions and effects of the present invention will be described in detail below in conjunction with the drawings through specific embodiments.

[0023] As Figure 1-7 shown, a working device of a new type of cylindrical clamping machine includes a frame 1. The two sides of the frame 1 are symmetrically hinged with booms 8, and the two booms 8 are connected by a bracket; the rear end of the boom 8 is connected to the frame through hinge eleven K, and the front end of the boom 8 is connected to the clamping device 6 through hinge six F. The clamping device 6 is the clamping part of the existing cylindrical clamping machine; a lifting hydraulic cylinder 9 is arranged between the boom 8 and the frame 1. The cylinder sleeve end of the lifting hydraulic cylinder 9 is connected to the frame 1 through hinge nine I, and the piston rod end of the lifting hydraulic cylinder 9 is connected to the boom 8 through hinge eight H. The rear end of the first connecting rod is connected to the frame through hinge one A, and the rear end is connected to the cylinder sleeve end of the tipping hydraulic cylinder 3 through hinge three C. The upper end of the second connecting rod is connected to the first connecting rod through hinge two B, and the lower end is connected to the boom 8 through hinge ten J. The piston rod end of the tipping hydraulic cylinder 3 is respectively connected to the first rocker arm 4 and the second rocker arm 5 through hinge four D. The lower end of the first rocker arm is connected to the boom 8 through hinge seven G, and the front end of the second rocker arm is connected to the clamping device 6 through hinge five E. The tipping hydraulic cylinder 3, the first rocker arm 4 and the second rocker arm 5 form a compound hinge at hinge four D, which increases the bearing capacity of the clamping device, makes the working device more stable during the clamping process, and has better operation effect.

[0024] The following describes a usage process of the present invention with reference to the drawings:

[0025] When the cylindrical clamping is required, the staff installs this working device on a suitable engineering vehicle. The clamping device of the cylindrical clamping machine is placed horizontally to start horizontally clamping the cylinder. When in the clamping working condition, the lifting hydraulic cylinder 8 is locked, and the turning hydraulic cylinder 3 shortens. At this time, the clamping device 6 turns. When the clamping device 6 turns to a certain position, the lifting hydraulic cylinder 8 and the turning hydraulic cylinder 3 are locked, and the clamping device 6 rotates 90° to ensure the stability of the cylinder. When in the boom lifting working condition, the turning hydraulic cylinder 3 is locked, and the lifting hydraulic cylinder 8 extends to push the boom up to a certain position. Subsequently, the whole machine clamps the cylinder for transportation. After transporting to a certain position, the lifting hydraulic cylinder 8 and the turning hydraulic cylinder 3 are locked, and the clamping device 6 rotates 90°. At this time, the lifting hydraulic cylinder 8 is locked, and the turning hydraulic cylinder 3 extends. The clamping device 6 is placed horizontally. When in the cylinder unloading working condition, the lifting hydraulic cylinder 8 shortens, the turning hydraulic cylinder 3 is locked, and the clamping device 6 moves downward to a certain position to place the cylinder at the designated position.

[0026] Since each component is under great stress when the clamping device 6 is fully loaded, the turning hydraulic cylinder 3 is connected to the first rocker arm and the second rocker arm to form a compound hinge, which can prevent uneven stress caused by excessive local stress on the second rocker arm. Therefore, the working device will not have insufficient rigidity during the material clamping process, and the stability of the whole machine is relatively high. The angle difference of the clamping device 6 is relatively large during the lifting process of the boom 8 of the traditional cylindrical clamping machine. It is known through simulation experiments that the rotation of the clamping device 6 is small and the translation performance is good during the lifting process of the boom 8 of the working device provided by the present invention. This device has high load-bearing capacity, high stability, a compact structure, and high working efficiency.

[0027] The solutions in the embodiments are not intended to limit the patent protection scope of the present invention. Any equivalent implementation or change that does not depart from the present invention is included in the patent scope of this case.
