Description

Technical Field

[0001] This utility model relates to a cylindrical part gripping technology, and more particularly to a cylindrical part gripping mechanical claw. Background Technology

[0002] Cylindrical parts are among the most common components in the machinery industry, typically machined on lathes or combination machine tools for both internal and external diameters. With increasing automation in the machining industry, using robotic grippers to pick up and load / unload cylindrical parts onto lathes or combination machine tools has become a standard practice. Current methods for gripping cylindrical parts mostly use compressed air as the power source for the robotic grippers. Because the grippers need to frequently move between the placement area of ​​the cylindrical part and the chuck of the lathe or combination machine tool, the overall structure of the grippers is relatively complex to prevent gas leakage and facilitate gripping, resulting in high manufacturing and maintenance costs. Furthermore, to continuously supply compressed air, dedicated gas compression, storage, and transmission pipelines are required, further increasing the machining and maintenance costs of cylindrical parts. Summary of the Invention

[0003] To address the above problems, this utility model proposes a cylindrical part gripper.

The shell is a cylinder with one end semi-closed, and three T-shaped slides are evenly distributed around its circumference at the semi-closed end. The three claws are three elongated claws with a T-shaped cross-section, which are slidably installed in the T-shaped slides of the shell. Each elongated claw has a claw post on its front and a threaded groove on its back. The claw post is positioned flush with the shell. On the circumference of the drive disc, the threaded groove is a three-segment planar thread evenly distributed and cut; the front end of the drive disc is provided with a planar thread that matches the threaded groove of the three-jaw jack and meshes with the threaded groove of the three-jaw jack; the rear end of the drive disc is provided with a circumferential internal tooth; the bearing is installed between the outer circle of the drive disc and the inner circle of the outer shell; the shaft of the motor is eccentrically fixed to the inner side of the rear cover; the gear is fixed on the motor shaft, and when the rear cover is fixed to the rear end of the outer shell, the gear meshes with the circumferential internal tooth of the rear end of the drive disc.

[0005] Furthermore, the upper half of the claw post is fitted with a rubber or plastic sleeve.

[0006] Furthermore, a pushing mechanism is provided on the front side of the semi-closed end of the outer shell, including: sliding columns, sliding plates, and springs: there are three sliding columns, which are evenly distributed and fixed on the front side of the semi-closed end of the outer shell; the sliding plate is Y-shaped, with three legs slidably mounted on the three sliding columns; there are three springs, which are respectively fitted between the bottom side of the sliding plate of the three sliding columns and the front side of the semi-closed end of the outer shell.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Detailed Implementation

[0015] See appendix Figure 2 , 3As shown in the figure, the cylindrical part gripping mechanical claw of this utility model uses electricity as a power source and includes: a shell 1, three claws 2, a drive disk 3, a bearing 4, a motor 5, a gear 6, and a rear cover 7; the shell is a cylinder with one end semi-closed, and three T-shaped slides are evenly distributed around the circumference at the semi-closed end of the shell; the three claws are three strip claws with a T-shaped cross-section, which are slidably installed in the T-shaped slides of the shell; each strip claw has a claw post on its front and a threaded groove on its back; wherein, the claw post is located at... On a circumference concentric with the outer shell, the threaded groove is three segments evenly distributed along a single planar thread. The front end of the drive disc has a planar thread matching the threaded groove of the three-jaw jack and meshes with it. A circumferential internal tooth is provided at the rear end of the drive disc. The bearing is installed between the outer circumference of the drive disc and the inner circumference of the outer shell. The motor's shaft is eccentrically fixed to the inner side of the rear cover. The gear is fixed to the motor shaft, and when the rear cover is fixed to the rear end of the outer shell, the gear meshes with the circumferential internal tooth at the rear end of the drive disc. This utility model, a cylindrical part-grabbing mechanical claw, uses electricity as a power source, greatly reducing structural complexity. Using electricity as a power source eliminates the need for compressed air pipelines and static or dynamic seals between pipelines and components, effectively reducing manufacturing and maintenance costs. This utility model relates to a cylindrical part gripping mechanical claw. The forward and reverse rotation of the motor drives the forward and reverse rotation of the drive disk, thereby causing the three strip claws to move along their respective T-shaped slides toward or away from the center. In turn, the claw posts on the strip claws clamp or release the cylindrical part located at the center.

[0016] As one of the preferred technical solutions, the upper half of the claw post is fitted with a rubber or plastic sleeve 8. Fitting the upper half of the claw post with a rubber or plastic sleeve can, on the one hand, increase the friction between the claw post and the outer circle of the cylindrical part, making the gripping more stable; on the other hand, it can prevent the claw post from damaging the outer surface of the cylindrical part.

[0017] See appendix Figure 4 , 5 As shown in the figure, as one of the preferred technical solutions, a pushing mechanism 9 is also provided on the front side of the semi-closed end of the shell, including: sliding columns 9-1, sliding plates 9-2, and springs 9-3. There are three sliding columns, evenly distributed and fixed to the front side of the semi-closed end of the shell. The sliding plate is Y-shaped, with three legs slidably mounted on the three sliding columns. There are three springs, each fitted between the bottom side of the sliding plate of the three sliding columns and the front side of the semi-closed end of the shell. This pushing structure allows the sliding plate, pushed by the springs, to axially move the cylindrical part into the chuck of a lathe or combination machine tool when the mechanical gripper releases the cylindrical part (see Appendix). Figure 5This allows the cylindrical part to be clamped by the chuck of a lathe or machine tool. Especially when the chuck of the lathe or machine tool is horizontal, the cylindrical part will not move into the chuck on its own without external force. Of course, with the addition of a pushing mechanism, the optimal gripping method for the mechanical jaws is to place the cylindrical part vertically on the flat plate. After the mechanical jaws move above the cylindrical part, they move vertically downwards, overcoming the spring tension to press the slide plate towards the outer shell, and then the motor is activated to clamp the cylindrical part between the three jaw posts. At this point, due to the clamping of the jaw posts, the spring tension cannot push the cylindrical part out of the jaw posts.

[0018] Obviously, the beneficial technical effect of this utility model of a cylindrical part gripper is that it uses electricity as a power source, which effectively simplifies the structure and effectively reduces manufacturing and maintenance costs.
