Description

Technical Field

[0001] The utility model belongs to the technical field of forging clamps, and in particular relates to a clamping device used in an automated precision forging automobile wheel hub bearing production line. Background Art

[0002] Forging is one of the most basic parts in various industrial productions and is widely used in industries such as automobiles, aerospace and ships. Precision forging means that after the parts are formed, they can be used as mechanical parts with little or no processing, that is, they are close to the shape of the parts. And the blanks are made according to the size requirements.

[0003] Precision forging technology is a new technology that is gradually improved and developed based on conventional forging technology. Advanced manufacturing technology integrates new materials, new energy, information technology, computer technology and other multidisciplinary high-tech technologies, and has the characteristics of high efficiency, energy saving, material saving, high precision, light weight and low cost. With the development of big data analysis technology, the development of machine technology, and the widespread application of learning and robots, the forging industry is also developing in the direction of automation, networking and intelligence. However, because its intelligence level is not high enough, it is not able to handle the faults that occur on the production line, and corresponding adjustments are made to this, especially for the clamping of precision forged parts. When the production line is running normally, the forging is ejected by the lower die ejection mechanism under normal operation of the production line. Both manual clamping and robot clamping require the forging to be completely demolded, that is, the ejection mechanism is required to eject the forging to a sufficient height. At this time, the robot will clamp the flash part of the hub bearing. The automobile hub bearing gripping device with the authorization announcement number CN210418367U adopts a pneumatic gripping component to grip the gripping part. However, the robot clamps are prone to instability when clamping, and the forgings may even flip or fall. The above recurring problems prevent the forgings from being accurately sent to the next process by the robot after being roughened, interrupting the rhythm of the entire production line. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a clamping device for use in an automated precision forged automobile wheel hub bearing production line. Combined with the size of the forging to be clamped and the characteristics of the clamp itself, the clamp can effectively solve the problem that the existing clamps need to constantly replace the jaws during clamping, which is too cumbersome to operate.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A clamping device used in an automated precision forged automobile wheel hub bearing production line comprises a jaw assembly, a floating assembly and a supporting assembly; the supporting assembly comprises a robot arm frame and a wedge block, a driving member is mounted on the robot arm frame, and the driving member is connected to the wedge block; the jaw assembly comprises two sets of oppositely arranged jaw seats and fixed jaws mounted on the jaw seats; the floating assembly is hinged with the jaw seats to drive the two oppositely arranged fixed jaws to move toward or away from each other to realize the clamping process.

[0007] Preferably, the floating assembly comprises a connecting rod and a pulling rod respectively hinged to the jaw seat, the connecting rod is connected to the inclined groove of the wedge block through a lever, and the pulling rod is hinged to the robot arm frame.

[0008] Preferably, the driving member is a telescopic cylinder, the piston rod of which is coaxially arranged with the wedge block to drive the telescopic movement of the wedge block.

[0009] Preferably, the jaw seat is L-shaped, and the fixed jaw is mounted on the vertical rod end of the L-shaped jaw seat by bolts.

[0013] The clamping device of the utility model is used for the robot forging automatic line. It is combined with the size of the forging to be clamped and the characteristics of the clamp itself, and can effectively solve the problem that the existing clamp needs to constantly change the jaws during clamping, and the operation is too cumbersome. At the same time, during the clamping process, it can ensure the parallel movement of the two jaw seats through the cooperation of the connecting rod, the pull rod and the wedge block. It has the advantages of large clamping range change, stable clamping force, reliable clamping, etc. It is especially suitable for on-site work where the roundness of the circular forgings clamped by the robot is slightly poor and the clamping range changes greatly; at the same time, it prevents the forgings from turning over and falling after turning over, and also avoids the situation where the robot arm cannot clamp the workpiece due to the tilt of the workpiece.
