Mechanical arm jaw structure

This creation belongs to the field of automation equipment, especially for a jaw structure of a robot arm that satisfies the gripping and moving of various workpieces and improves the efficiency of automation work.

With the advancement of industrial technology, automation has become an important issue that most operators cannot ignore. By coordinating and controlling multiple devices, the production process can be automatically realized according to the needs of the operators. In addition to greatly increasing production capacity, it can also be reduced. Problems caused by human manipulation and intervention.

In most automated devices, robotic arms are a fairly common known device. The robotic arm is an automated device that mimics the function of the human arm for various tasks. One of the tasks is to grip the workpiece, then rotate or move it, and move the workpiece to the proper position for the smooth operation of the automation.

Therefore, how to effectively grip the workpiece to adapt to different work requirements is an important design of the robot arm. A common gripping technique is to have a jaw on the front end of the robot arm, and the gripper is used to grip the workpiece, and then the position of the mechanical arm is changed, and finally the jaw is relaxed. The workpiece reaches the specified position.

The above-mentioned jaw design as a moving workpiece has only a basic function of opening and clamping because of simple operation, and there is no special point. However, with the complexity of the production line or the limitations of the production space, the movement of the workpiece may become more complicated. For example, there is a difference in height between the inlet end and the outlet end of the workpiece, an angle change, or a different moving position according to the state of the workpiece. In this way, the basic jaw design is not enough, but it needs to be combined with more complicated robotic arm design, and even more sets of robot arms and jaws can be mixed to achieve complex automation applications.

However, whether it is a more complicated design or a plurality of robotic arms, the cost is bound to increase. Moreover, if there is space limitation in the production line, how to effectively arrange a plurality of mechanical arms is also a headache. Furthermore, complex line configurations mean maintenance difficulties and may reduce the efficiency of automated operations.

It can be seen that there are still problems in the design of the habit that need to be solved, rather than a good design. According to the above-mentioned shortcomings, the creators of this case started to improve and actively research and innovate. Through long-term research and development and implementation, the jaw structure of the mechanical arm can be completed.

The main purpose of this creation is to provide a gripper structure for a robot arm, which is suitable for gripping and moving various workpieces to meet the needs of the operator, and can improve the efficiency of the automation work.

Another object of the present invention is to provide a jaw structure of a robot arm, which can be applied to different workpiece clamping operations by a single jaw, simplifying the configuration and production of the production line. Process to reduce equipment construction costs.

The purpose of this creation is to provide a jaw structure of a mechanical arm, which can be applied to most mechanical arms without changing the original mechanical arm structure, so that the operator can select according to his own needs and has great flexibility in use.

A further object of the present invention is to provide a jaw structure of a mechanical arm, which has a simple structure, is not easily damaged, and is easy to maintain, so that the production line can maintain normal automatic operation and reduce the loss of operation due to maintenance or replacement.

In order to solve the above technical problem, the present invention provides a jaw structure of a mechanical arm, which comprises a pair of jaws, a positioning group and a rotating cylinder.

The jaw group has a clamping jaw connected to a jaw cylinder, the jaw cylinder driving the jaw to move the workpiece, and the positioning group is used to assemble the jaw group. And positioning the positioning group to the robot arm; the rotating cylinder is disposed between the positioning group and one of the clamping jaw groups to drive the clamping jaw group to perform a rotating operation.

With the foregoing design, the same arm has two jaw sets, and at least one of the jaw sets can be rotated by the rotary cylinder. Therefore, it is more flexible in operation, and different jaw sets can be selected according to the requirements of the workpiece to meet the needs of automated work.

Further, the power output end of the jaw cylinder locks the intrinsic jaw fixing block, and the jaw is locked on the jaw fixing block; and the positioning group has a fixing plate for locking the jaw And a rotating cylinder, the fixing plate is provided with a fixing block at one end thereof, and the clamping block is used to lock the two clamping jaw groups to the robot arm.

The aforementioned locking method is performed by screws to obtain stable fixing and capacity Disassemble and replace.

In addition, the rotating cylinder is used to control one of the clamping jaws to obtain a flexible operation, but two rotating cylinders may be disposed at the same time, and are respectively disposed between the positioning group and the two clamping jaw groups. The two jaw sets can be freely rotated to obtain greater operational flexibility and meet the operational requirements.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments; FIG. 1 is a view showing an embodiment of a jaw structure of the robot arm; FIG. 2 is a schematic structural view of a jaw structure of the robot arm; FIG. 4 is a detailed view of the structure of the jaw group of the jaw structure of the arm; FIG. 4 is a detailed structural view of the jaw structure of the jaw structure of the robot arm; .

As shown in Figures 1 to 4, this creation is a jaw structure of a mechanical arm, which is mainly applied to the needs of work automation operations, reducing the complexity of the production line and improving work efficiency.

The jaw structure 100 includes two jaw sets 110, and both of the jaw sets 110 have jaws 111. The jaws 111 are in the form of a clamp, and the workpieces 200 are gripped by opening and folding. The jaw 111 is connected to the jaw cylinder 112. The jaw cylinder 112 is driven by air pressure, and the jaw 111 is driven to grip the workpiece 200. The size of the workpiece 200 is controlled by the pressure of the jaw 111. To accommodate different workpieces 200.
