Description

Technical Field

[0001] This utility model relates to the field of fixed gripper technology, specifically an extended fixed gripper. Background Technology

[0002] The chuck is a key clamping component on a lathe chuck, and its core function is to stabilize and fix the workpiece to facilitate cutting. The extended fixed chuck is a special clamping component of the lathe chuck. Its core value lies in breaking through the functional boundaries of conventional chucks and providing stable clamping support for special machining scenarios. The extended feature gives it the ability to extend the clamping range, which can adapt to the clamping requirements of long shaft workpieces and other needs, allowing the chuck to reach more special clamping positions.

[0003] Traditional extended grippers often use rigid connection methods such as welding or one-piece casting for the gripper head and gripper arm. Once this structure is formed, it cannot be adjusted. When dealing with round workpieces, a curved gripper head is needed; when holding square objects, a flat gripper head is needed; and when handling fragile items, a gripper head made of flexible material is required, the fixed connection design makes it impossible to replace the gripper with an appropriate part as needed. This results in extremely poor versatility of the gripper, which can often only work on a single size and shape of object. Moreover, replacing the gripper head to replace the gripper is time-consuming and costly. Utility Model Content

[0004] The purpose of this invention is to provide an extended fixed gripper to solve the problem that the gripper head and gripper arm of traditional grippers are fixed in a fixed way, and it is impossible to change the gripper head to a suitable one according to the shape and size of different objects being gripped.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An extended fixed gripper includes a gripper base. Multiple gripper arms arranged in a circular array are movably connected to the surface of the gripper base. A gripper head is detachably connected to the surface of each gripper arm. An upper sliding frame is fixedly connected to the outer surface of each gripper arm, and a lower sliding frame is fixedly connected to the outer surface of each gripper arm. A linkage slider is slidably connected between the upper and lower sliding frames. A reinforcing rib is fixedly connected to the surface of the linkage slider. A mating plate is fixedly connected to the surface of the gripper head, and a through hole is provided on the surface of the mating plate for the reinforcing rib to pass through.

[0007] Preferably, a limiting bolt is installed between the upper sliding frame and the lower sliding frame. The limiting bolt forms an abutment with the right side surface of the linkage slider to restrict the linkage slider from moving to the right.

[0008] Preferably, the limiting bolt movably penetrates the surface of the upper sliding frame, and the bottom end of the limiting bolt is provided with a threaded head. The limiting bolt is threadedly connected to the lower sliding frame through the threaded head.

[0009] Preferably, a T-shaped block is fixedly connected to the right side surface of the gripper head, and a T-shaped groove for the T-shaped block to be inserted is provided on the left side surface of the gripper arm, with the opening of the T-shaped groove facing the reinforcing rib.

[0010] Preferably, two symmetrically arranged inlay plates are fixedly connected to the right side surface of the gripper head, and the surface of the gripper arm is provided with an inlay groove for the inlay plates to be inlaid.

[0011] Preferably, the surface of the inlay plate is provided with a threaded hole, and a screw is threadedly connected to the inlay plate through the threaded hole. The surface of the gripper arm is provided with a through hole for the screw to pass through.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The gripper head is detachably connected to the gripper arm via a T-block, which facilitates installation and disassembly. This design allows the gripper to be quickly replaced with a suitable gripper head according to the shape and size requirements of different gripped objects, greatly improving the versatility and flexibility of the gripper and reducing replacement costs and time costs.

[0014] 2. By arranging reinforcing ribs along the length of the gripper arm and passing through the mating plate of the gripper head, a through-type reinforced structure is formed. This design can effectively disperse the bending force on the gripper during the gripping process, significantly improve the overall bending strength and rigidity of the gripper, and is especially suitable for scenarios where extended grippers are prone to deformation under stress, thus extending the service life of the gripper.

[0015] 3. The T-slot opening faces the reinforcing rib. When the reinforcing rib passes through the mating plate, it will form a lateral limit on the gripper head. Together with the longitudinal limit of the T-block and T-slot, the double restriction prevents the gripper head from separating from the gripper arm when under force. The inlay plate and inlay groove increase the contact area between the gripper head and the gripper arm, further improving the tightness of the connection between the two.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution.

[0025] An extended fixed gripper includes a gripper base 1. Multiple gripper arms 2 arranged in a circular array are movably connected to the surface of the gripper base 1. Each gripper arm 2 has a gripper head 5 detachably connected to its surface, facilitating easy replacement of the gripper head 5. An upper sliding frame 8 and a lower sliding frame 9 are fixedly connected to the outer surface of each gripper arm 2. The upper and lower sliding frames 8 and 9 are symmetrically arranged. A linkage slider 11 is slidably connected between the upper and lower sliding frames 8 and 9. A reinforcing rib 12 is fixedly connected to the surface of the linkage slider 11, and the reinforcing rib 12 is arranged along the length of the gripper arm 2. The surface of the gripper head 5 is fixedly connected to... A docking plate 13 is attached, and a through hole for the reinforcing rib 12 to pass through is provided on the surface of the docking plate 13. A limiting bolt 10 is installed between the upper sliding frame 8 and the lower sliding frame 9. The limiting bolt 10 forms an abutment fit with the right side surface of the linkage slider 11 to restrict the linkage slider 11 from moving to the right. When the gripper head 5 is assembled onto the gripper arm 2, the reinforcing rib 12 is driven to pass through the docking plate 13 by sliding the linkage slider 11. Then, the limiting bolt 10 is used to limit the linkage slider 11 to prevent the linkage slider 11 from moving and causing the reinforcing rib 12 to separate from the docking plate 13. By setting the reinforcing rib 12, it is beneficial to increase the bending strength and rigidity of the gripper.

[0026] The limiting bolt 10 moves through the surface of the upper sliding frame 8. The bottom end of the limiting bolt 10 is provided with a threaded head. The limiting bolt 10 is threadedly connected to the lower sliding frame 9 through the threaded head. When the linkage slider 11 moves to the leftmost end of the upper sliding frame 8 and the lower sliding frame 9, the limiting bolt 10 passes through the upper sliding frame 8 and is threadedly connected to the lower sliding frame 9. At this time, the limiting bolt 10 is just in contact with the right side surface of the linkage slider 11, thereby restricting the movement of the linkage slider 11.

[0027] A T-shaped block 6 is fixedly connected to the right side surface of the gripper head 5, and a T-shaped groove 7 for the T-shaped block 6 to be inserted is provided on the left side surface of the gripper arm 2. The opening direction of the T-shaped groove 7 is towards the reinforcing rib 12. With the above arrangement, the gripper head 5 is detachably connected to the gripper arm 2 by inserting the T-shaped block 6 into the T-shaped groove 7. Since the opening direction of the T-shaped groove 7 is towards the reinforcing rib 12, the gripper head 5 and the gripper arm 2 can be prevented from disconnecting when the reinforcing rib 12 passes through the docking plate 13.

[0028] Two symmetrically arranged inlay plates 4 are fixedly connected to the right side surface of the gripper head 5. The surface of the gripper arm 2 is provided with an inlay groove 3 for the inlay plates 4 to be inlaid. By setting the inlay plates 4, it is beneficial to increase the contact area between the gripper arm 2 and the gripper head 5.

[0029] The surface of the inlay plate 4 is provided with a threaded hole 14, and a screw 16 is threadedly connected to the inlay plate 4 through the threaded hole 14. The surface of the gripper arm 2 is provided with a through hole 15 for the screw 16 to pass through. By setting the screw 16 to pass through the inlay plate 4 and the gripper arm 2 in sequence, it is beneficial to increase the stability of the connection between the gripper arm 2 and the gripper head 5.

[0030] Specifically, the solution is as follows: align the T-shaped block 6 on the right side surface of the gripper head 5 with the T-shaped groove 7 on the left side surface of the gripper arm 2, and simultaneously align the two inlay plates 4 on the right side of the gripper head 5 with the inlay groove 3 on the surface of the gripper arm 2, so that the T-shaped block 6 is embedded in the T-shaped groove 7 and the inlay plates 4 are inlaid into the inlay groove 3, thus completing the initial detachable connection between the gripper head 5 and the gripper arm 2.

[0031] Slide the linkage slider 11, causing the reinforcing rib 12 to move to the left along the length of the gripper arm 2, so that the reinforcing rib 12 passes through the through hole on the mating plate 13 on the surface of the gripper head 5, and moves the linkage slider 11 to the leftmost end of the upper sliding frame 8 and the lower sliding frame 9. Move the limiting bolt 10 through the surface of the upper sliding frame 8, so that the threaded head at its bottom end is threadedly connected to the lower sliding frame 9 and tightened. At this time, the limiting bolt 10 is in contact with the right side surface of the linkage slider 11, restricting the linkage slider 11 from moving to the right and preventing the reinforcing rib 12 from separating from the mating plate 13.

[0032] Screw 16 into the threaded hole 14 on the surface of the insert plate 4, and then through the through hole 15 on the surface of the gripper arm 2, to further increase the stability of the connection between the gripper arm 2 and the gripper head 5.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
