Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a gripper for a multi-station turret. Background Technology

[0002] A multi-station turret refers to a turret designed with multiple independent tool mounting positions. Each tool mounting position can be pre-installed with different functional tools (such as turning tools, drills, milling cutters, etc.), and the tool switching is automatically controlled by a CNC system. This design allows the machine tool to complete multiple operations continuously in a single setup without manual intervention for tool changing.

[0003] The existing method of clamping multi-station tool turrets involves the operator manually moving the turret. However, the raw material of the multi-station tool turret is a casting, which is heavy and difficult to move, making the installation of the multi-station tool turret inconvenient. At the same time, there is a risk of the multi-station tool turret falling during the operation, which could injure the operator. This poses certain safety hazards to the operator during the installation process. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a gripper for a multi-station turret, thereby solving the technical problem of how to make the installation of a multi-station turret convenient and improve its safety.

[0005] The objective of this utility model can be achieved through the following technical solution: a gripper for a multi-station turret, comprising finger cylinders, wherein the finger cylinders comprise two base fingers that can move relative to each other, characterized in that a square-shaped finger pad is fixedly connected to the inner side of the outer end of each base finger, each finger pad has several inclined positioning surfaces for fitting with the turret on its inner side, and each finger pad has several protruding positioning posts for positioning the turret on its inner side, all of the positioning posts forming a circle.

[0006] The gripper is located at the end of the robotic arm. The robotic arm drives the gripper to move. During operation, the translation of the base finger causes part of the sidewall of the turret's outer peripheral wall to fit against the positioning surface. At this time, the positioning post just surrounds the protruding part of the turret's outer peripheral wall, thus achieving the positioning of the irregularly shaped turret and preventing the turret from sliding. This ensures good stability of the turret after the gripper grasps it. Thus, the robotic arm and gripper can drive the movement of multi-station turrets, achieving automated mechanical movement. This makes the installation of multi-station turrets convenient, and the turret will not fall and injure the operator, improving safety.

[0007] In the aforementioned gripper for a multi-station turret, each finger pad has eight positioning surfaces. These eight positioning surfaces are arranged in pairs, with the two surfaces in each pair connected at an obtuse angle. The four pairs of positioning surfaces are arranged in a circular array. This structure eliminates the need to select an orientation during finger pad installation, ensuring that the positioning surfaces conform to the outer perimeter of the turret after installation, thus facilitating finger pad installation.

[0008] In the aforementioned gripper for a multi-station turret, each finger pad has eight positioning posts, located on eight positioning surfaces. The eight positioning posts are arranged in pairs, with the four pairs forming a circular array. This structure eliminates the need to select a direction during finger pad installation. After installation, the positioning posts surround the protruding portion of the turret's outer wall, improving the stability of the turret installation.

[0009] In the aforementioned gripper for a multi-station tool turret, several positioning grooves are spaced apart along their axial direction on the outer wall of the positioning post. Several positioning pins are detachably mounted in the finger pad, each positioning pin corresponding to a positioning post. The inner end of each positioning pin can be inserted into a positioning groove to position the positioning post and the finger pad. This structure allows for adjustment of the extended length of the positioning post, enabling the gripper to be adjusted for different tool turrets, ensuring the stability of the gripper's grip on the tool turret, thereby improving safety and versatility.

[0010] In the aforementioned gripper of a multi-station turret, the finger cylinder further includes a rectangular cylinder body. The base finger is disposed on the front end face of the cylinder body, and a connecting plate for connection with a robotic arm is attached and fixed to the rear end face of the cylinder body. The connecting plate allows for better connection between the gripper and the robotic arm, facilitating the connection between them.

[0011] In the aforementioned gripper of a multi-station turret, both sides of the rear end face of the cylinder have protruding edges, and several fixing holes are spaced apart on the protruding edges. The two sides of the connecting plate respectively abut against two of the protruding edges. Fasteners pass through the fixing holes and are inserted into the connecting plate to securely connect the cylinder to the connecting plate. This structure improves the fit between the cylinder and the connecting plate and facilitates the secure connection between them.

[0012] Compared with the prior art, the gripper for a multi-station turret provided by this utility model has the following advantages:

[0013] 1. This gripper is used to grip the tool turret. The robotic arm and gripper drive the multi-station tool turret to move, realizing the mechanical automation of the tool turret movement and making the installation of multi-station tool turrets convenient.

[0014] 2. This gripper uses positioning surfaces and positioning posts to position the turret, enabling the gripper to grasp irregularly shaped turrets. After the gripper grasps the turret, the turret has good stability and will not fall, thus preventing it from hitting the operator and improving safety. Attached Figure Description

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 , Figure 2 As shown, the gripper of this multi-station turret 6 includes a finger cylinder 1, a finger pad 2, a positioning post 3, a positioning pin 4, and a connecting plate 5.

[0022] The finger cylinder 1 includes two relatively translatable base fingers 11 and a cuboid cylinder 12. The base fingers 11 are disposed on the front end face of the cylinder 12, and a connecting plate 5 for connecting with a robotic arm is attached and fixed to the rear end face of the cylinder 12. Specifically, both sides of the rear end face of the cylinder 12 have protruding flanges 121. In this embodiment, four fixing holes 122 are provided at intervals in the flanges 121. The two sides of the connecting plate 5 are respectively attached to two flanges 121. Fasteners such as bolts pass through the fixing holes 122 and are inserted into the connecting plate 5 to fix the cylinder 12 to the connecting plate 5. In actual production, the number of fixing holes 122 can be three or six.

[0023] Each base finger 11 has a square-shaped finger pad 2 fixed to the inner side of its outer end, such as... Figure 3As shown, each finger pad 2 has eight inclined positioning surfaces 21 on its inner side for fitting with the turret 6. The eight positioning surfaces 21 are arranged in pairs, with the two positioning surfaces 21 in the same group connected and arranged at an obtuse angle. The four groups of positioning surfaces 21 are arranged in a ring array. Each finger pad 2 also has eight protruding positioning posts 3 on its inner side for positioning the turret 6. All the positioning posts 3 form a circle, with the eight positioning posts 3 located in the eight positioning surfaces 21 respectively. The eight positioning posts 3 are arranged in pairs, with the four groups of positioning posts 3 arranged in a ring array.
