[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. 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.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This invention provides a fixture and cutting equipment to solve the technical problem that existing workpiece fixtures cannot simultaneously accommodate cylindrical and square workpieces.

[0023] refer to Figures 1 to 6 The breast volume ultrasound device disclosed in this embodiment includes: a support base, a clamping assembly mounted on the support base, and a driving device; the clamping assembly includes a clamping frame 15, an adjusting plate 18, and a locking device. The clamping frame 15 is U-shaped and has two members, which are slidably mounted on the support base with their openings facing each other. Each clamping frame 15 has two adjusting plates 18. The adjusting plates 18 are rectangular, and the two adjusting plates 18 are symmetrically mounted inside the opening of the clamping frame 15. The sides of the two adjusting plates 18 that are close to each other are free sides, and the sides that are far from each other are hinged to the upper and lower ends of the opening, respectively. The locking device is mounted on the clamping frame 15 and is used to adjust the swing angle of the adjusting plate 18 and lock the angle of the adjusted plate 18 after adjustment. The driving device is used to drive the two clamping frames 15 to move back and forth or towards each other on the support base so that the opening side of the clamping frame 15 clamps or releases the workpiece.

[0024] In this embodiment, the clamping assembly is provided with two clamping frames 15 in pairs, and each clamping frame 15 is provided with two adjusting plates 18. The two adjusting plates 18 are symmetrically installed inside the opening of the clamping frame 15. At the same time, after the locking device is locked in place, the adjusting plates 18 provided on each clamping frame 15 can only deflect towards the opposite clamping frame 15.

[0025] When a square workpiece needs to be processed, the locking device is released, and the sway angle of the adjusting plate 18 is adjusted so that the two adjusting plates 18 of each clamping frame 15 are in a vertical position, that is, the two adjusting plates 18 are at 180°. Then the locking device is opened to lock the position of the adjusting plate 18 of each clamping frame 15. After the preparation is completed, the square workpiece to be processed is suspended between the two clamping frames 15 by the robotic arm. The drive device is started to drive the two clamping frames 15 to move towards each other on the support until the adjusting plate 18 acts on the side wall of the square workpiece, thereby achieving the clamping of the workpiece.

[0026] When machining a cylindrical workpiece, after releasing the locking device, the free edge of the adjusting plate 18 needs to be tilted at a certain angle away from the other clamping frame 15, so that the two adjusting plates 18 in each clamping frame 15 form a V shape. The angle between the two adjusting plates 18 can be adjusted according to the diameter of the cylindrical workpiece. Then, the locking device is opened to lock the position of the adjusting plate 18 in each clamping frame 15. After the preparation is completed, the cylindrical workpiece to be machined is suspended between the two clamping frames 15 using a robotic arm. The drive device is started to move the two clamping frames 15 towards each other on the support until the adjusting plate 18 acts on the surface of the cylindrical workpiece, forming a double V-shaped clamping limit, thereby achieving the clamping and fixing of the workpiece.

[0027] refer to Figures 3 to 4In this embodiment, the clamping frame 15 has inwardly bent flanges 26 at both ends, with mounting holes on the flanges 26. The locking device includes a rotating rod 19 and a ratchet mechanism. The rotating rod 19 is rotatably mounted on two opposite mounting holes. The adjusting plate 18 is fixedly mounted on the rotating rod 19 located between the two flanges 26. The ratchet 20 of the ratchet mechanism is mounted on the end of the rotating rod 19 exposed on the flange 26. The anti-return pawl 21 of the ratchet mechanism is rotatably mounted on the flange 26 on the same side as the ratchet 20 via a rotating shaft 22. An elastic element is also provided between 22 and the folded edge 26 to press the anti-return pawl 21 onto the ratchet 20; the size of the folded edge 26 only needs to meet the requirements of the mounting hole opening, and there is no need to extend it excessively into the clamping frame 15 to avoid the folded edge 26 interfering with the clamping workpiece; a bearing is also installed between the rotating rod 19 and the mounting hole, the rotating rod 19 is fixedly installed in the inner ring of the bearing, and the outer ring of the bearing is fixedly installed in the mounting hole to improve the adjustment flexibility of the rotating rod 19 and prevent the rotating rod 19 from falling off. It should be noted that the forward movement of the ratchet 20 structure limits the free side of the adjustment plate 18 to only deflect towards the opposite clamping frame 15. When locked, the adjustment plate 18 cannot deflect in the opposite direction. The elastic element is a torsion spring, which is specifically installed by sleeve on the rotating shaft 22. One end of the torsion spring is engaged with the folded edge 26, and the other end of the torsion spring is engaged with the anti-return pawl 21. Through the elasticity of the torsion spring, the anti-return pawl 21 is pressed against the ratchet 20. Furthermore, in order to facilitate the rotation of the adjustment plate 18, a lever 23 is also fixedly installed on the anti-return pawl 21 for manual operation by the operator.

[0028] In this embodiment, the support base has a through groove 17 parallel to the moving direction of the clamping frame 15. A threaded sleeve located in the through groove 17 is installed at the bottom of the clamping frame 15, and the axial direction of the threaded sleeve is the same as the axial direction of the through groove 17. The threads inside the threaded sleeves installed on the two clamping frames 15 have opposite directions. The driving device includes a drive motor 14 and a threaded rod 16 installed at the output end of the drive motor 14. The threaded rod 16 cooperates with the threaded sleeve. By rotating the drive motor 14, the relative distance between the two clamping frames 15 is adjusted. The drive motor 14 is installed on one side of the support base, and the output end of the drive motor 14 faces the through groove 17 to facilitate the installation of the threaded rod 16. It should be noted that, for those skilled in the art, the driving device can also be a cylinder or a hydraulic cylinder. If a cylinder is used, two cylinders can be installed symmetrically on the support base, and the output ends of the cylinders can be connected to the clamping frames 15. After the cylinder is started, the two clamping frames 15 can be moved in opposite directions or towards each other. No specific limitation is made here.

[0029] In this embodiment, the support base is provided with a groove 25 parallel to the moving direction of the clamping frame 15. A slider is installed at the bottom of the clamping frame 15 corresponding to the position of the groove 25. The slider of the clamping frame 15 is embedded in the groove 25 and slides with the support base. There are two parallel grooves 25, and two sliders are installed at the bottom of each clamping frame 15. The movement stability of the clamping frame 15 is improved by the cooperation of the slider and the groove 25.
