[0009] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0010] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0011] Please see Figures 1 to 5As shown, the coupler tail seat clamp provided in this embodiment of the present invention includes a clamp body 110 and a clamping assembly 120 for clamping the coupler tail seat; there are two sets of clamping assemblies 120, which are symmetrically arranged facing each other at both ends of the clamp body 110, and a robotic arm connector 130 is provided on one side of the clamp body 110; the clamping assembly 120 includes a pressure plate 121 and a driving device 122, the pressure plate 121 is hinged to the clamp body 110, the driving device 122 is fixedly connected to the clamp body 110, and the driving end of the driving device 122 is hinged to the pressure plate 121.
[0012] In practice: The hook tail seat fixture is a specialized fixture used for precisely gripping the hook tail seat of a close-fitting car coupler. It can work with a robot to complete the handling of the hook tail seat. The fixture consists of a fixture body 110, a pressure plate 121, a drive device 122, a connecting rod 123, and a positioning pin 140. The special fixture is equipped with a robotic arm connector 130 for quick assembly with the robot. The overall design of the fixture adopts a symmetrical structure to ensure the stability and balance of operation.
[0013] After the hook tail seat is disassembled or assembled, the robot moves the gripper to the designated gripping position on the hook tail seat. Once the positioning pin 140 is aligned with the hook tail seat, the gripper moves into position along the direction of the positioning pin 140. Then, the drive device 122 operates, causing the pressure plate 121 to move towards the hook tail seat, clamping it tightly and ensuring the hook tail seat is fully constrained by the gripper, forming a stable whole. The robot, through the gripper, can precisely complete the gripping action of the hook tail seat; the entire process is stable and accurate.
[0014] The entire fixture is made of high-strength metal material. The pressure plate 121 undergoes special treatment (e.g., processing anti-slip textures or setting anti-slip rubber pads; the same special treatment is applied to the contact area between the fixture body 110 and the hook tail seat) to ensure sufficient friction between the pressure plate 121 and the hook tail seat during clamping, while avoiding damage to the surface of the hook tail seat. The drive device 122 can be driven by various methods such as electric, hydraulic, and pneumatic.
[0015] Furthermore, the fixture body 110 includes a fixture part and a mounting part. The fixture part is a part with a storage groove 150. Both ends of the fixture part are mounting parts for mounting clamping components. The two mounting parts are in the same plane. When the fixture clamps the hook tail seat, the mounting part abuts against the edge of the hook tail seat and cooperates with the pressure plate 121 to fix the hook tail seat.
[0016] The pressure plate of the aforementioned coupler tail seat fixture is hinged to the fixture body. In conjunction with the drive device that is fixedly connected to the fixture body, the opening and closing of the pressure plate is controlled. When the pressure plate is open, the hook tail seat can enter the clamping space of the fixture body. The drive device controls the pressure plate to close, and the pressure plate, together with the fixture body, clamps the edge of the hook tail seat. The robotic arm connector on the fixture can be combined with a robot to realize the automatic assembly of the hook tail seat by the robot.
[0017] As one possible implementation, the fixture also includes connecting rods 123; both ends of the connecting rods 123 are hinged to the fixture body 110 and the pressure plate 121, respectively. Further, the connecting rods 123 are divided into two groups, each group corresponding to one pressure plate 121. Each group contains at least two connecting rods 123, and the two connecting rods 123 are symmetrically arranged on both sides of the end of the fixture body 110 in a hinged manner. The pressure plate 121 is also connected to the connecting rods 123 in a hinged manner.
[0018] When the driving device 122 drives the pressure plate 121 to clamp the hook tail seat, the connecting rod 123 can form a parallel clamping space between the pressure plate 121 and the fixture body 110, ensuring the clamping effect on the edge of the hook tail seat, and also facilitating the driving effect of the driving device 122 on the pressure plate 121.
[0019] As one possible implementation, the fixture also includes positioning pins 140; the positioning pins 140 are symmetrically arranged on the side of the fixture body 110 away from the robotic arm connector 130. Furthermore, each set of positioning pins 140 consists of two pins, symmetrically arranged on both sides of the storage groove on the fixture body 110.
[0020] The positioning pin 140 can cooperate with the guide hole (mounting hole) on the hook tail seat to achieve the positioning of the hook tail seat, and together with the pressure plate 121, it can better achieve the clamping effect of the hook tail seat.
[0021] As one possible implementation, the clamp also includes a storage groove 150 for storing the end of the hook tail seat; the storage groove 150 is disposed on the other side of the clamp body 110.
[0022] The storage slot 150 is based on the structure of the hook tail seat, which ensures that the edge of the hook tail seat can make better contact with the clamp body 110, thus ensuring the clamping effect of the clamp on the hook tail seat.
[0023] As one possible implementation, the two ends of the receiving groove are provided with notches 155 for receiving the protruding part of the end of the hook tail seat. Furthermore, the two positioning pins 140 in each group are symmetrically arranged on both sides of the notch.
[0024] The notch 155 facilitates the protruding part of the hook tail seat end to pass through, allowing the storage slot to completely store the end of the hook tail seat, ensuring the clamping effect of the hook tail seat.
[0025] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0026] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
