Description

Technical Field

[0001] The utility model relates to the technical field of clamp tooling, in particular to an elastic clamp. Background Art

[0002] A connector is a device used to connect two or more electronic components, electrical devices or cables together. Connectors come in a variety of types and sizes, and different connectors are available for different application scenarios.

[0003] The shape of the connector is different, and the process used to assemble the connector will also vary. For rectangular connectors, a clamp is usually used to grasp them. The clamp can easily grasp them by applying pressure on both sides. However, when this clamp grasps a cylindrical connector, the contact surface between the clamp and the connector is too narrow, resulting in inaccurate grasping, which is easy to drop and damage the connector.

[0004] Therefore, the grabbing tool in the prior art has the technical defects of being unstable in grabbing the circular connector and being easy to fall off. Utility Model Content

[0009] Baffles, the number of which is set to be several, the several baffles are arranged on the free ends of the clamping plate in a one-to-one correspondence, and the angle between the baffles and the clamping plate is an obtuse angle;

[0010] Wherein, in a state without external force, the angle between the clamping plate and the mounting rod is A, and in a grasping state, the angle between the clamping plate and the mounting rod is B, and A is smaller than B.

[0011] Through the above structure, the clamping plate and the mounting rod are elastically connected so that the clamping plate and the mounting plate form a claw-like structure. In a natural state, the clamping plate rebounds in the direction away from the end face of the mounting plate, thereby increasing the distance between different clamping plates, so that a grasping space is formed between the free ends of different clamping plates; when the staff needs to grasp the grasped structure, they only need to align the grasping space with the grasped structure and move the relative position of the mounting rod and the sleeve so that the mounting rod moves in the direction away from the clamping plate, thereby The contact between the clamping plate and the inner wall of the sleeve causes the grasping space to gradually shrink, so that the clamping plate is in close contact with the object to be grasped, and the grasping space is contracted by moving the position of the mounting rod in the sleeve, thereby realizing the function of grasping the object to be grasped; when the grasping is completed and the object to be grasped needs to be placed, the mounting rod can be displaced in the reverse direction to increase the grasping space and place the object to be grasped, and the baffle is fixedly set on the clamping plate, so that the multi-layer cylindrical structure objects can be stably clamped.

[0015] In some examples of the present invention, a counterweight block is provided at one end of several side plates facing away from the mounting plate, and the side plates, the counterweight block and the mounting plate form a sealed cavity.

[0016] In some examples of the present invention, the mounting plate further includes a conduit, the conduit is adapted to the mounting hole, the conduit is fixedly disposed on the mounting plate, and the conduit is located on a side where the mounting plate is connected to the sleeve.

[0017] In some examples of the present invention, a guide rod is further included. The guide rod is located inside the sleeve, and both ends of the guide rod are fixedly connected to the mounting rod and the driving end of the driving structure respectively.

[0020] Additional aspects and advantages of the present invention will be partially given in the following description and partially become apparent from the following description, or will be understood through the practice of the present invention that the present invention can stably grasp cylindrical structural members. Specifically, the elastic connection between the clamping plate and the mounting rod allows the clamping plate and the mounting plate to form a claw-like structure. In a natural state, the clamping plate rebounds toward the end face direction away from the mounting plate, thereby increasing the distance between different clamping plates, thereby forming a grasping space between the free ends of different clamping plates; when the staff needs to grasp the structure to be grasped, they only need to align the grasping space with the structure to be grasped, and move the relative position of the mounting rod and the sleeve to make the mounting rod move in the direction away from the clamping plate, so that the inner walls of the clamping plate and the sleeve contact each other, causing the grasping space to gradually shrink, so that the clamping plate and the object to be grasped are in close contact, and the contraction of the grasping space is achieved by moving the position of the mounting rod in the sleeve, thereby realizing the function of grasping the object to be grasped; when the grasping is completed and the object to be grasped needs to be placed, the function of increasing the grasping space and placing the object to be grasped can be achieved by reversely displacing the mounting rod, and by fixing a baffle on the clamping plate, the objects of the multi-layer cylindrical structure can be stably clamped.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] In the prior art, the most common way to assemble cylindrical connectors is to put a rubber sleeve on the connector and use flat-nose pliers to grab it to complete the assembly. However, this technology is extremely dependent on the proficiency of the workers, and has low labor efficiency, unstable grabbing, and easy to drop. The clamps in the prior art are only suitable for grabbing rectangular connectors. Grabbing cylindrical connectors will cause technical problems such as unstable grabbing and easy damage. Specifically, rectangular connectors are usually grabbed by applying pressure on both sides to complete easy grabbing. Then, when this chuck grabs the cylindrical connector, the contact surface between the chuck and the connector is too narrow, resulting in inaccurate grabbing and easy falling to damage the connector.

[0041] Therefore, the grabbing tool in the prior art has the technical defects of being unstable in grabbing the circular connector and being easy to fall off.

[0042] The utility model provides an elastic chuck which can stably grasp a circular structural part, wherein: Figure 1 A schematic diagram of the main structure of an elastic chuck provided by the utility model; Figure 2 A schematic cross-sectional view of an elastic chuck provided by the utility model; Figure 3 This is a schematic diagram of the installation structure of the installation rod 20 provided by the utility model.

[0043] Reference below Figure 1-Figure 3 An elastic chuck according to an embodiment of the present utility model is described, comprising: a sleeve 10;

[0044] A mounting rod 20, one end of which is sleeved inside the sleeve 10, and the other end of which extends out of the sleeve 10, so that the mounting rod 20 can move back and forth in the axial direction inside the sleeve 10;

[0045] The clamping plate 30 is elastically connected to one end of the mounting rod 20 extending out of the sleeve 10, so that the clamping plate 30 rebounds away from the end surface direction of the mounting rod 20. The elastic connection method can adopt a spring sheet. The above function is achieved by setting the spring sheet. The clamping plates 30 are provided with a plurality of clamping plates 30, and the plurality of clamping plates 30 are distributed in a circumferential array. The number of the clamping plates 30 can be set to six, eight or other numbers. In the present embodiment, the number of the clamping plates 30 is set to eight. When the number of the clamping plates 30 is set to eight, the contact area between the clamping plates 30 and the grasped structure is gradually increased, thereby making the grasping more stable.

[0046] Baffles 40, the number of baffles 40 is set to be several, and the baffles 40 are arranged one by one at the free end of the clamping plate 30, and the angle between the baffles 40 and the clamping plate 30 is an obtuse angle. In this embodiment, the number of baffles 40 is eight, and the angle between the baffles 40 and the clamping plate 30 is 150°;

[0047] In the state without external force, the angle between the clamp plate 30 and the mounting rod 20 is A, and in the grasping state, the angle between the clamp plate 30 and the mounting rod 20 is B, A is less than B, wherein A and B are the angles between the clamp plate 30 and the axial side of the mounting rod 20.

[0048] The cross-sectional shapes of the sleeve 10 and the mounting rod 20 are generally circular, so as to facilitate the installation of the clamping plate 30 into a circular array structure.

[0049] Through the above structure, the clamping plate 30 and the mounting rod 20 are elastically connected, so that the clamping plate 30 and the mounting plate 60 form a claw-like structure. In a natural state, the clamping plate 30 rebounds in the direction away from the end face of the mounting plate 60, thereby increasing the distance between different clamping plates 30, so that a grasping space is formed between the free ends of different clamping plates 30; when the staff needs to grasp the grasped structure, they only need to align the grasping space with the grasped structure and move the relative position of the mounting rod 20 and the sleeve 10, so that the mounting rod 20 moves in the direction away from the clamping plate 30. As a result, the clamping plate 30 and the inner wall of the sleeve 10 come into contact with each other, causing the grasping space to gradually shrink, so that the clamping plate 30 is in close contact with the object to be grasped, and the grasping space is contracted by moving the position of the mounting rod 20 in the sleeve 10, thereby realizing the function of grasping the object to be grasped; when the grasping is completed and the object to be grasped needs to be placed, the mounting rod 20 can be displaced in the reverse direction to increase the grasping space and place the object to be grasped, and the baffle 40 is fixedly set on the clamping plate 30, so that the multi-layer cylindrical structure objects can be stably clamped.

The driving structure 50 is usually a cylinder, and the cylinder can drive the mounting rod 20 to move along the side wall of the sleeve 10. At the same time, the driving structure 50 can have a variety of options, such as an electric telescopic rod, a hydraulic cylinder, etc. In this embodiment, a cylinder is selected to ensure the sensitivity of the elastic chuck. During use, the opening and closing of the splint 30 during the grasping process can be quickly realized. At the same time, the pressure pushed by the cylinder will eventually be transmitted to the supporting force applied by the splint 30 and the baffle 40 to the grasped structure. The greater the supporting force, the greater the friction force applied by the splint 30 and the baffle 40 to the grasped structure, and the clamping is more stable. Selecting a cylinder as a driving device can also ensure the stability during the clamping process.

At the same time, the counterweight block 70 can further enhance the stability of the elastic chuck during the displacement process, facilitating coordinated work with other devices.
