Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a four-jaw curved precision component clamping and placement tool. Background Technology

[0002] Precision parts cannot be produced and processed without the assistance of clamping devices. Due to the special nature of precision parts, the requirements for clamping devices are extremely strict. They must be easy to clamp and use, but must not cause any damage to the precision parts, so as not to affect the performance of the precision parts.

[0003] Existing four-jaw grippers (such as jewelry grippers) are generally straight grippers, which have the following problems in actual use:

[0004] 1. When clamping precision parts, the grippers can only grip the object vertically, which does not provide a good operating angle and makes operation inconvenient;

[0005] 2. The straight gripper is operated by pressing the claws out, which results in poor operating comfort.

[0006] 3. When gripping small, irregularly shaped objects, it is difficult to observe them, leading to gripping errors and poor operational precision;

[0007] 4. For some complex clamping positions and long-term clamping operations, straight grippers are not suitable for use in these scenarios. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a four-jaw curved precision parts clamping and placement tool to solve the problems existing in the background art.

[0009] This utility model provides the following technical solution: a four-claw curved precision parts clamping and placement tool, including a claw tube, with a clamping claw elastically installed inside the claw tube, a tube head threaded to one end of the claw tube, and a pressing head for installing the clamping claw movably inserted inside the tube head, and a curved claw outlet threaded to the other end of the claw tube so that the extended clamping claw forms an angle.

[0010] Preferably, a gripping piece is provided at one end of the claw tube near the tube head, and an assembly part for assembling the gripper is provided inside the claw tube.

[0011] Preferably, one end of the gripper is provided with a spring and a connecting part, wherein the spring is placed on one side of the assembly part and abuts against the assembly part, and the connecting part is threadedly connected to the pressing head.

[0012] Preferably, the gripper includes a gripper bar and four resilient gripper hooks.

[0013] Preferably, the gripper bar passes through the assembly part and is slidably assembled with the assembly part.

[0014] Preferably, the curved claw opening has an arc-shaped structure with an angle of 120°-150°.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features a curved claw opening. The curved claw opening structure allows the extended part of the gripper to form a certain angle, enabling the user to see the gripping position more clearly when gripping objects, thus avoiding misoperation. The curved design also makes operation more flexible, easily reaching corners and edges that are difficult to reach with straight grippers. It offers excellent ease of operation, precision, and comfort for gripping and placing complex positions and small irregularly shaped parts.

[0017] 2. This utility model has a gripping plate on the claw tube. When using it, the index and middle fingers support the gripping plate, and the thumb presses the pressing head to squeeze the claw out of the claw tube for clamping. This operation method conforms to the ergonomic design and will not cause hand fatigue even after long-term use, greatly improving the comfort of operation. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0025] This utility model provides a four-jaw clamping and placing tool for curved precision parts, such as... Figure 1-5 As shown, it includes a claw tube 1, a tube head 2, a pressing head 3, a curved claw outlet 4, and a gripper 5. Specifically, the gripper 5 is elastically installed inside the claw tube 1. One end of the claw tube 1 is threaded to the tube head 2, and the pressing head 3 is movably inserted into the tube head 2. The other end of the claw tube 1 is threaded to a curved claw outlet 4, which has an arc-shaped structure with an angle of 120°. Depending on the application scenario, angles such as 130°, 140°, 120°, and 150° can be selected to make the extended gripper 5 form an angle.

[0026] During operation, press the pressing head 3 firmly to make it contact the gripper 5 until the gripper 5 is pushed out of the curved claw opening 4. The curved claw opening 4 creates an angle for the extended portion of the gripper 5, allowing the user to clearly see the gripping position when picking up objects, thus avoiding misoperation. The curved design also makes operation more flexible, easily reaching corners and edges that are difficult to reach with straight grippers. It offers excellent ease of operation, precision, and comfort for gripping and placing complex locations and small, irregularly shaped parts (e.g., gripping and placing dental crowns; its unique curved design allows the operator to more easily observe and handle details).

[0027] A gripping plate 11 is also provided at one end of the claw tube 1 near the tube head 2. When in use, the gripping plate 11 is held with the index and middle fingers, and the pressing head 3 is pressed with the thumb, so that the gripper 5 is squeezed out of the claw tube 1 for clamping. This operation method conforms to the ergonomic design and will not cause hand fatigue even after long-term use, greatly improving the comfort of operation.

[0028] Furthermore, the inside of the claw tube 1 is also provided with an assembly part 12 for assembling the gripper 5. Specifically, the gripper 5 includes a claw bar 51 and four elastic claw hooks 52. The claw bar 51 of the gripper 5 passes through the assembly part 12 and is slidably assembled with the assembly part 12 to support the gripper 5 and guide the entire gripper 5.

[0029] It can be explained here that the four claw hooks 52 are initially constrained by the claw tube 1, causing the four claw hooks 52 to close together. When the four claw hooks 52 are squeezed out of the curved claw opening 4, they lose the constraint of the claw tube 1 and the four claw hooks 52 expand outwards respectively, so as to wrap the object to be clamped. When the clamping claw 5 retracts, the four claw hooks 52 are once again constrained by the claw tube 1 and come together to complete the clamping of the object.

[0030] Furthermore, one end of the gripper 5 is provided with a spring 6 and a connecting part 7. The gripper 5 is elastically installed inside the gripper tube 1 through the spring 6 and the connecting part 7. Specifically, the spring 6 is placed on one side of the assembly part 12 and abuts against the assembly part 12, and the connecting part 7 is threadedly connected to the pressing head 3.

[0031] The working principle of this utility model is as follows: Hold the gripper 11 with your index and middle fingers, and press the pressing head 3 with your thumb. Under pressure, the spring 6 is compressed, which causes the claw bar 51 to move at a constant speed along the assembly part 12 toward the curved claw outlet 4. This causes the claw hooks 52 to extend evenly from the curved claw outlet 4 and to spread outward. After the four claw hooks 52 are aligned with the object to be clamped, release the pressing head 3, the spring 6 rebounds, and the gripper 5 retracts, clamping the object at the same time.

[0032] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0033] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
