Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, specifically to an adjustable rotary clamp. Background Technology
[0002] In modern industrial manufacturing, fixtures, as key devices for clamping and positioning workpieces, are widely used in many production processes such as machining, welding, assembly, and inspection. They play a vital role in ensuring the stability and accuracy of workpieces during processing, and in improving production efficiency and product quality.
[0003] Currently, most fixtures on the market adopt a fixed-angle design. The positioning angle and clamping direction of these fixtures are fixed and can only meet the machining or assembly needs of a specific workpiece from a single angle. When dealing with complex workpieces with multi-faceted and multi-directional machining requirements, multiple sets of fixtures must be relied upon, which greatly increases the complexity of production. Therefore, there is an urgent need for a fixture that can meet the machining needs of multiple angles and directions. Utility Model Content
[0004] To address the issue of existing clamps having only one angle, this application provides an adjustable rotary clamp, employing the following technical solution: An adjustable rotary clamp, comprising: beam; A fixed side support rod is fixedly connected to one end of the crossbeam; The movable side support rod is horizontally slidably connected to the other end of the crossbeam; The clamp has two grippers, one rotatably connected to the fixed side support rod and the other rotatably connected to the movable side support rod; A rotating assembly for driving the gripper on the fixed side support rod to rotate; A clamping and adjusting assembly is used to drive the sliding side support rod to slide.
[0005] By adopting the above technical solution, when the rotary fixture starts working, the workpiece is positioned between the grippers on both sides. Based on the workpiece width, the clamping adjustment component activates to adjust the distance between the two sides, driving the two grippers closer together until they are tightly fitted to both sides of the workpiece and clamped securely. When it is necessary to adjust the workpiece machining angle, the rotary component activates, and the workpiece rotates synchronously with the grippers to the preset angle, facilitating subsequent machining. The rotary component, through the grippers, can drive the workpiece to achieve 360° continuous rotation or precise positioning to a specific angle, breaking through the limitations of traditional fixed-angle fixtures. Multi-directional machining can be completed in a single clamping, improving the adaptability to complex workpieces.
[0006] Optionally, the rotating component includes: A rotating shaft is rotatably connected to the fixed side support rod and the movable side support rod respectively, and the clamp is fixedly connected to the corresponding rotating shaft; A rotary motor, mounted on the fixed side support rod, is used to drive the rotation of the corresponding rotating shaft.
[0007] By adopting the above technical solution, the rotating component can achieve flexible adjustment of the workpiece at multiple angles, meet the diverse requirements of different processing steps for the workpiece angle, and greatly improve processing efficiency.
[0008] Optionally, the rotating component further includes: The counterweight is fixedly connected to the rotating shaft of the movable side support rod.
[0009] By adopting the above technical solution, after processing, the counterweight assists the gripper to overcome its own weight and inertia, and smoothly return to the initial position.
[0010] Optionally, the clamping adjustment assembly includes: A linear guide rail is mounted on the crossbeam; The slider is fixedly connected to the movable side support rod and slidably connected to the linear guide rail; A clamping cylinder is mounted on the crossbeam, and the piston rod is fixedly connected to the slider.
[0011] By adopting the above technical solution, after the clamping cylinder is started, the piston rod extends and drives the slider to slide back and forth, thereby driving the movement of the moving side support rod. When the appropriate distance is adjusted, the clamping cylinder clamps the fixed side support rod and the moving side support rod at the same time, thus completing the clamping and fixing.
[0012] Optionally, the adjustable rotary clamp further includes: Lifting lugs are installed at both ends of the crossbeam for connection to an external crane.
[0013] By adopting the above technical solutions, the rotary fixture can be quickly transferred to different processing areas, realizing convenient hoisting and flexible transfer of the rotary fixture as a whole.
[0014] Optionally, a polyurethane pad is installed on the contact surface between the gripper and the workpiece.
[0015] By adopting the above technical solution, we can enhance the clamping stability, avoid scratches on the workpiece surface, and ensure the appearance quality of the workpiece after processing.
[0016] Optionally, the adjustable rotary clamp further includes: The controller is electrically connected to both the clamping cylinder and the rotary motor.
[0017] By adopting the above technical solutions, automated control can be achieved, thereby improving operational efficiency.
[0018] In summary, this application has at least the following beneficial effects: 1. The rotary motor can drive the workpiece to rotate continuously 360° or be precisely positioned to a specific angle through the gripper, breaking through the limitations of traditional fixed angle fixtures. Multi-directional processing can be completed in one clamping, improving the adaptability to complex workpieces.
[0019] 2. The contact surface between the clamp and the workpiece is made of polyurethane padding, which can enhance the clamping stability, prevent scratches on the workpiece surface, and ensure the appearance quality of the workpiece after processing. Attached Figure Description

[0022] This application discloses an adjustable rotary clamp. (Refer to...) Figure 1 The rotating clamp includes a crossbeam 1, a lifting lug 2, a fixed side support rod 3, a movable side support rod 4, a gripper 5, a rotating assembly 6, and a clamping adjustment assembly 7.
[0023] The lifting lugs 2 are fixedly installed at both ends of the crossbeam 1 for connection to an external crane, allowing the rotating clamp to be quickly transferred to different processing areas. The fixed side support rod 3 is fixedly connected to one end of the crossbeam 1; the movable side support rod 4 is horizontally slidably connected to the other end of the crossbeam 1; two grippers 5 are provided, one rotatably connected to the fixed side support rod 3 and the other rotatably connected to the movable side support rod 4. Furthermore, a polyurethane pad (not shown in the figure) is installed on the contact surface between the gripper 5 and the workpiece to enhance clamping stability and prevent scratches on the workpiece surface. The rotating assembly 6 is installed on the fixed side support rod 3 to drive the gripper 5 on the fixed side support rod 3 to rotate; the clamping adjustment assembly 7 is installed below the crossbeam 1 to drive the movable side support rod 4 to slide.
[0024] The rotating assembly 6 includes a rotating shaft 61, a rotating motor 62, and a counterweight 63.
[0025] Rotating shafts 61 are rotatably connected to the fixed-side support rod 3 and the movable-side support rod 4, respectively, and the gripper 5 is fixedly connected to the corresponding rotating shaft 61. A rotary motor 62 is fixedly mounted on the fixed-side support rod 3, and its output shaft drives the corresponding rotating shaft 61 of the fixed-side support rod 3 to rotate via a reducer. A counterweight 63 is fixedly connected to the rotating shaft 61 of the movable-side support rod 4, and is used to assist the gripper 5 on the movable-side support rod 4 in overcoming its own weight and inertia and smoothly returning to its initial position after the workpiece is processed.
[0026] The clamping adjustment assembly 7 includes a linear guide rail 71, a slider 72, and a clamping cylinder 73.
[0027] Linear guide rail 71 is fixedly mounted on crossbeam 1; slider 72 is fixedly connected to movable side support rod 4 and slidably connected to linear guide rail 71. The cylinder body of clamping cylinder 73 is horizontally fixedly mounted on crossbeam 1, and the piston rod is fixedly connected to slider 72.
[0028] Reference Figure 2 The rotary fixture also includes a controller 8, which is electrically connected to the rotary motor 62 and the clamping cylinder 73.
[0029] The implementation principle of an adjustable rotary clamp according to an embodiment of this application is as follows: When the rotary fixture starts working, the workpiece is positioned between the two grippers 5. Based on the workpiece width, the controller 8 activates the clamping cylinder 73, driving the moving side support rod 4 to slide along the linear guide rail 71 to adjust the distance between the two sides until the two grippers 5 are tightly fitted to both sides of the workpiece and clamped securely. When it is necessary to adjust the workpiece machining angle, the controller 8 activates the rotary motor 62, and the workpiece rotates synchronously with the grippers 5 to the preset angle, facilitating subsequent machining. The rotary motor 62, through the grippers 5, can drive the workpiece to achieve 360° continuous rotation or precise positioning to a specific angle, breaking through the limitations of traditional fixed-angle fixtures. Multi-directional machining can be completed with a single clamping, improving the adaptability to complex workpieces.
