Description

Technical Field

[0001] This utility model relates to the field of aluminum wheel casting technology, specifically a pin-type gripper. Background Technology

[0002] In the manufacturing process of aluminum alloy automotive parts, robotic arms are needed to remove castings from the die-casting machine. These castings are then subjected to processes such as slag removal by hammering, water cooling, and placement into a trimming machine. The robotic arm clamps the casting stalk with grippers, the contact area of ​​which is machined with teeth to prevent slippage. These teeth are prone to wear, requiring replacement of the grippers and resulting in high maintenance costs. Utility Model Content

[0003] In view of this, the present invention aims to propose a pin-type gripper, in which the pin is fixed to the gripper by a thread, and only the worn pin needs to be replaced during maintenance, thereby reducing costs.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A pin-type gripper includes a pin made of a set screw, one side of which is machined into a pointed shape; a gripper body, which is bolted to the gripper cylinder of a robot, and the top of the gripper body has multiple threaded through holes machined in the contact area with the workpiece for mounting the pin; and an internal hexagonal flat-end set screw, which is screwed into the gripper body to fasten the pin in the threaded hole and prevent the pin from loosening.

[0006] In some embodiments, a positioning ring mounting hole is machined on the bottom of the gripper body.

[0007] In some embodiments, the ejector pin is made of high-strength steel and undergoes quenching and tempering treatment after manufacturing.

[0008] Compared with the prior art, the pin-type gripper of this utility model has the following advantages:

[0009] The clamping jaws disclosed in this utility model hold the material shank using multiple set screws. The set screws are threaded onto the top of the clamping jaws, so only the worn set screws need to be replaced during maintenance, reducing maintenance costs. Furthermore, the extension distance of each set screw can be adjusted individually, allowing for better adaptation to the shape of the material shank and ensuring that each set screw can grip the shank, thus increasing the clamping force.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The following is for reference. Figures 1 to 7 The pin-type gripper of the present invention is described in conjunction with the embodiments.

[0023] A pin-type gripper includes a pin 1, a hexagonal set screw 2, a gripper body 3, and a bolt 4. The gripper body 3 is mounted on the gripper cylinder of a robot via the bolt 4. The top of the gripper body 3, where it contacts the workpiece, has multiple threaded holes for mounting the pin 1. The pin 1 is made of a set screw, with one side of the set screw's conical surface machined into a pointed shape. The pin is screwed into the threaded hole at the top of the gripper body 3. After determining the position according to the material shank, the hexagonal set screw 2 is screwed in and tightened to prevent the pin from loosening.

[0024] The bottom of the gripper body is machined with a positioning ring mounting hole to ensure that the gripper body 3 and the gripper cylinder are securely installed and accurately positioned.

[0025] Ejector pin 1 can be made of high-strength steel and heat-treated after manufacturing to increase hardness and delay wear.

[0026] Compared with the prior art, the pin-type gripper of this utility model has the following advantages:

[0027] The clamping jaws disclosed in this utility model hold the material shank using multiple set screws. The set screws are threaded onto the top of the clamping jaws, so only the worn set screws need to be replaced during maintenance, reducing maintenance costs. Furthermore, the extension distance of each set screw can be adjusted individually, allowing for better adaptation to the shape of the material shank and ensuring that each set screw can grip the shank, thus increasing the clamping force.
