Description

Technical Field

[0001] This utility model relates to the field of chucks, and in particular to a chuck for a workstation tool. Background Technology

[0002] Robotic arms are the most widely used automated mechanical devices in the field of robotics, found in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although they vary in form, they all share a common characteristic: they can receive commands and precisely position themselves at a point in three-dimensional (or two-dimensional) space to perform operations. Robotic arms require grippers to grasp materials during use.

[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: some existing tool chucks at workstations need to be switched to different types of chucks when producing different batches of products. When switching, the original chucks need to be disassembled and new chucks need to be installed, which is quite troublesome. Therefore, a tool chuck at workstations is proposed. Utility Model Content

[0004] To address the problem that existing tool chucks at certain workstations require switching to different types of chucks when producing different batches of products, and that switching requires disassembling the original chucks and installing the new ones, which is cumbersome, this invention provides a tool chuck for workstations.

[0005] This utility model provides a tool chuck for a workstation, employing the following technical solution:

[0006] A tool chuck for a workstation includes a base and a robotic arm mounted on the base. A mounting frame is provided on one side of the robotic arm, and a motor is mounted on the mounting frame. A connecting rod is fixedly mounted on the output end of the motor, passing through the mounting frame. A connecting plate is fixedly mounted on the end of the connecting rod away from the motor. Three clamping walls are evenly spaced on the outer surface of the connecting plate. A mounting plate is fixedly mounted on one end of each of the three clamping walls. A first electric push rod is fixedly mounted inside the mounting plate. A mounting block is fixedly mounted on the output end of the first electric push rod. A chuck is hinged to the mounting block. There are three types of chucks, and these three different types of chucks are sequentially mounted on the three clamping walls. A support rod is hinged to the outer surface of the mounting plate, and one end of the support rod is hinged to the chuck.

[0007] A locking block is fixedly installed on one side of the mounting plate. A locking groove adapted to the locking block is opened inside the clamping wall. A spring is fixedly installed inside the clamping wall. A moving plate is fixedly installed on one end of the spring. A limiting block is fixedly installed on one side of the moving plate. A limiting groove adapted to the limiting block is opened inside the locking block. A pull rod is fixedly installed on the side of the moving plate away from the limiting block.

[0008] By adopting the above technical solution, when facing different types of products, the motor can drive the connecting rod and connecting plate to rotate, the connecting plate can drive the three clamping walls to rotate, and the three clamping walls can drive three different types of jaws to rotate, so that the type of jaws can be quickly switched. After switching, the operator only needs to control the extension and retraction of the first electric push rod. The first electric push rod can drive the jaws to rotate with the cooperation of the mounting block and the support rod, thereby completing the clamping of the product.

[0009] Optionally, a rubber shock-absorbing plate is fixedly installed on the bottom of the base.

[0010] By adopting the above technical solutions, rubber damping plates can reduce vibration and noise, and protect equipment and the surrounding environment.

[0011] Optionally, the end of the pull rod away from the moving plate extends through to the outside of the clamping wall and is fixedly connected to a handle.

[0012] By adopting the above technical solution, the handle makes it convenient for staff to pull the lever to move.

[0013] Optionally, a second electric push rod is fixedly installed on the outer surface of the mounting frame. A hollow annular plate is fixedly installed on the telescopic end of the second electric push rod through the mounting frame. An annular canvas is fixedly installed on the upper surface of the hollow annular plate. The side of the annular canvas away from the hollow annular plate is fixedly connected to the mounting frame.

[0014] By adopting the above technical solution, after use, the staff can activate the second electric push rod, which can drive the hollow annular plate to move downwards. The hollow annular plate can drive the annular canvas to move downwards, thereby protecting the claws under the mounting frame and reducing the impact of external objects on the claws.

[0015] Optionally, a slider is fixedly installed on the outer surface of the movable plate, and a groove adapted to the slider is provided inside the clamping wall.

[0016] By adopting the above technical solution, the slider and the groove can limit the movement range of the moving plate, and at the same time make the moving plate move more smoothly.

[0017] Optionally, a rubber anti-slip pad is fixedly installed on the inner side of the claw.

[0018] By adopting the above technical solution, the rubber anti-slip pad can increase the anti-slip performance of the gripper and increase the friction between the gripper and the product, making the gripper more stable when picking up the product.

[0019] Optionally, the end of the limiting block away from the moving plate is provided with a guide angle that is inclined toward the locking block.

[0020] By adopting the above technical solution, when installing the mounting plate, the locking block on the mounting plate can push the moving plate to squeeze the spring through the guide angle, thereby enabling the mounting plate to be installed quickly.

[0021] Optionally, a protective shell is fixedly installed on the mounting bracket, the motor is located inside the protective shell, a heat dissipation groove is provided on the top of the protective shell, and a heat dissipation mesh is fixedly installed on the inner wall of the heat dissipation groove inside the protective shell.

[0022] By adopting the above technical solution, the protective shell can protect the motor and reduce the contact between the motor and external objects. During use, the heat generated by the motor can be transferred to the outside through the heat dissipation groove and heat dissipation mesh. The heat dissipation mesh can reduce the entry of external impurities and dust into the protective shell.

[0023] In summary, this utility model has the following beneficial effects:

[0024] 1. When facing different types of products, the motor can drive the connecting rod and the connecting plate to rotate, the connecting plate can drive the three clamping walls to rotate, and the three clamping walls can drive the three different types of claws to rotate, so that the type of claw can be quickly switched. After switching, the operator only needs to control the extension and retraction of the first electric push rod. The first electric push rod can drive the claws to rotate with the cooperation of the mounting block and the support rod, thereby completing the clamping of the product.

[0025] 2. When the claw needs to be disassembled, repaired, or cleaned, the operator only needs to pull the handle. The handle can control the movement of the limit block, and the limit block can be separated from the limit groove on the claw block. This allows the operator to quickly remove the mounting plate and repair or clean the claw on the mounting plate.

[0026] 3. After the utility model is used, the staff can start the second electric push rod, which can drive the hollow annular plate to move downward. The hollow annular plate can drive the annular canvas to move downward, thereby protecting the claws under the mounting frame and reducing the impact of external objects on the claws.
