Detailed Implementation

[0020] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 1 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a servo clamping and positioning device, including a support component 1, a horizontal drive mechanism 2 and a clamping component 3;

[0022] The support assembly 1 includes a support 11 and a mounting plate 12, with the mounting plate 12 fixed to the upper end of the support 11;

[0023] The horizontal drive mechanism 2 includes a servo cylinder 21. The fixed end of the servo cylinder 21 is fixed to the upper end of the mounting plate 12. The telescopic rod of the servo cylinder 21 is connected to the clamping assembly 3 and is used to drive the clamping assembly 3 to move horizontally and accurately position different vehicle models.

[0024] The clamping assembly 3 is located on the upper end of the mounting plate 12 and on one side of the horizontal drive mechanism 2. It includes a base plate 301, a vertical plate 303, a cylinder 304, a gripper 305, a swing arm 306, a connecting rod 307, a cylinder 308, and a clamping block 309. One end of the base plate 301 is connected to the telescopic rod of the servo electric cylinder 21. The vertical plate 303 is vertically connected to the upper end of the base plate. The cylinder 304 is symmetrically arranged on one side of the vertical plate 303. One end of the cylinder 304 is rotatably connected to the gripper 305. The swing arm 306 is integrally connected to one side of the gripper 305. A rotating shaft passes through the center of the gripper 305 and the swing arm 306. The rotating shaft rotates within the cylinder 304. The gripper 305 and the integrally connected swing arm 306 are both sleeved on the outer side of the rotating shaft. A connecting rod 307 is provided between the two swing arms 306. The two ends of the connecting rod 307 are respectively hinged to the two swing arms 306. A clamping block 309 is fixed to the tail end of the gripper 305. A cylinder 308 is provided on the upper surface of the base plate 301. The telescopic end of the cylinder 308 is hinged to the lower end of one of the grippers 305. Through the telescopic movement of the cylinder 308, one of the grippers 305 and the swing arm 306 are driven to rotate. Then, under the action of the connecting rod 307, the other swing arm 306 and the gripper 305 swing synchronously to achieve clamping and positioning of the frame.

[0025] Furthermore, in order to prevent damage caused by uneven force on the servo cylinder 21 during operation, a first hinge seat 302 is provided on one side of the base plate 301 during operation, and a spherical sleeve 22 is provided at the end of the telescopic rod of the servo cylinder 21. The spherical sleeve 22 is located inside the first hinge seat 302 and the two are connected by a hinge.

[0026] Furthermore, the telescopic end of the cylinder 308 is connected to a second hinge seat 311, and the gripper 305 is located inside the second hinge seat 311 and the two are connected by a hinge.

[0027] Furthermore, to prevent the two grippers 306 from over-positioning during the swinging process, a limit rod 312 is provided diagonally above one of the cylinders 304.

[0028] To ensure the linearity of the horizontal movement of the clamping assembly 3 driven by the servo electric cylinder 21, protrusions 310 are evenly distributed on one side of the base plate 301, and a linear guide rail 4 is provided on the upper surface of the mounting plate 12. The protrusions 310 are slidably connected in the side guide groove of the linear guide rail 4.

[0029] To prevent damage to the wiring of cylinder 308 during horizontal movement, a cable chain assembly 5 is provided above servo cylinder 21. The cable chain assembly 5 includes a cable chain 51, a connecting plate 52, and a cable chain fixing box 53. The cable chain fixing box 53 is installed on the upper end of the mounting plate 12, and servo cylinder 21 passes through the cable chain fixing box 53. One end of the cable chain 51 is located inside the cable chain fixing box 53, and the other end of the cable chain 51 is connected to the connecting plate 52. The connecting plate 52 is fixedly connected to the base plate 301. By concentrating the wiring of cylinder 308 inside the cable chain 51, tangling and knotting of the wiring are prevented.

[0030] In use: When the frame arrives at the handover station, according to the length of the vehicle model, the servo cylinder 21 is activated to push the clamping assembly 3 to move horizontally to the appropriate clamping position. Then, the cylinder 308 is activated and retracts, thereby driving one of the clamping jaws 305 to rotate outward. Under the hinge action of the connecting rod 307, the other clamping jaw 305 is driven to rotate outward synchronously, so that the two clamping jaws 305 are in an open state. When the frame is suspended between the two clamping jaws 305, the cylinder 308 extends, causing the two clamping jaws 305 to swing inward to clamp and fix the frame.

[0031] This invention solves the problem of not being able to arrange multiple locators due to space constraints, while enabling the co-production of multiple vehicle models on the same line. It accurately clamps and positions the frame according to different vehicle models, greatly improving ease of use.
