Description

Technical Field

[0001] This utility model relates to the field of processing technology, specifically a flexible stacked valve processing fixture. Background Technology

[0002] The flexible stacked valve employs a layered design, consisting of multiple valve plates with different functions stacked together. Each valve plate has a specific function, such as pressure control, flow regulation, and direction switching. By rationally selecting and arranging these valve plates, various hydraulic or pneumatic functions can be integrated.

[0003] Currently, some existing fixtures do not adequately consider the complex shape of flexible stacked valves in their design. Flexible stacked valves may have irregular shapes or special structural features, and the clamping components of traditional fixtures cannot fit tightly against the valve surface, resulting in unstable clamping. In view of this, we propose a machining fixture for flexible stacked valves. Utility Model Content

[0004] The main objective of this invention is to provide a flexible stacked valve processing fixture that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a flexible stacked valve processing fixture, including a support, a worktable fixedly connected to the support, the worktable fixedly connected to a placement table, and an elastic clamping device and a rotating clamping device provided on the worktable. The elastic clamping device includes:

[0006] A fixed plate is fixedly connected to the surface of the worktable. A motor is installed on the fixed plate, and the output shaft of the motor passes through the fixed plate and is fixedly connected to the moving rod.

[0007] A fixed platform is fixedly connected to the outer wall of the worktable. A connecting plate is fixedly connected to the fixed platform. A moving rod passes through the connecting plate. A fixed ring is fixedly connected to the moving rod. The fixed ring is elastically connected to the connecting plate by a spring.

[0008] The surface of the movable rod has a groove, and a sliding rod is engaged in the groove. The sliding rod is slidably connected in the limiting seat and in the through plate. A convex ring is fixedly connected to the sliding rod, and the convex ring is elastically connected to the through plate by a spring.

[0009] Preferably, the rotating clamping device includes a linear drive device, and the lower surface of the worktable is fixedly connected to the linear drive device.

[0010] Preferably, the output end of the linear drive device is fixedly connected to a hinge rod, and the end of the hinge rod away from the linear drive device is connected to a hinged rotating plate. Through the operation of the linear drive device, the output end is driven to pass through the worktable and lift the hinge rod upward.

[0011] Preferably, the rotating plate is rotatably connected to a rotating wheel, and the hinge rod drives the rotating plate forward to approach the flexible stacked valve. The rotating wheel can reduce friction between the rotating plate and the valve while ensuring that a stable pressure is applied to the valve.

[0012] Preferably, a hinge plate is rotatably connected to the rotating plate, and the hinge plate is rotatably connected to the hinge seat. The rotating plate can maintain a stable posture during movement, and through the cooperation of the hinge plate and the hinge seat, it can better withstand the reaction force from the flexible stacked valve, ensuring the reliability of the clamping action.

[0013] Preferably, the upper surface of the workbench is fixedly connected to a hinge seat, and the rotating clamping device is provided in multiple sets.

[0014] This utility model provides a flexible stacked valve machining fixture. It has the following beneficial effects:

[0015] (1) The flexible stacked valve processing fixture, through the set elastic clamping device, the synergistic action of spring one and spring two, enables the elastic clamping device to provide adaptive clamping force according to the actual shape, size and material characteristics of the flexible stacked valve. For flexible stacked valves of different specifications and materials, the device can automatically adjust the clamping force to avoid deformation or damage to the valve due to excessive clamping force, while ensuring sufficient clamping force to prevent displacement of the valve during processing.

[0016] (2) The flexible stacked valve processing fixture is equipped with a rotating clamping device. The linear drive device drives the output end to pass through the worktable and lift the hinge rod upward. The hinge rod drives the rotating plate to move forward and the rotating wheel contacts the flexible stacked valve. The rotating wheel can reduce the friction between the rotating plate and the valve and ensure that a stable pressure is applied to the valve. During the movement, the rotating plate can better withstand the reaction force from the flexible stacked valve through the cooperation of the hinge plate and the hinge seat, ensuring the reliability of the clamping action, avoiding the scratches or wear on the valve surface that may be caused by rigid contact, which is beneficial to protecting the surface quality of the flexible stacked valve, further enhancing the stability of the clamping, and ensuring the positional accuracy of the valve during the processing.

[0025] 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.

[0026] Please see Figures 1-4 This utility model proposes a flexible stacked valve processing fixture, including a support 1, a worktable 2 fixedly connected to the support 1, the worktable 2 being fixedly connected to a placement table 3, and an elastic clamping device 4 and a rotating clamping device 5 provided on the worktable 2. The elastic clamping device 4 includes a fixing plate 41.

[0027] In this embodiment of the utility model, to ensure processing accuracy and quality, specifically, a fixed plate 41 is fixedly connected to the surface of the workbench 2. A motor 42 is mounted on the fixed plate 41, and the output shaft of the motor 42 passes through the fixed plate 41 and is fixedly connected to the moving rod 43. When the motor 42 is turned on, its output shaft drives the moving rod 43 to move. A fixed platform 44 is fixedly connected to the outer wall of the workbench 2, and a connecting plate 45 is fixedly connected to the fixed platform 44. The moving rod 43 passes through the connecting plate 45 and is fixedly connected to a fixed ring 46. The fixed ring 46 is elastically connected to the connecting plate 45 via a spring 47. During the forward movement of the moving rod 43, the fixed ring 46 stretches the spring 47, causing the spring 47 to elastically deform and store spring energy. The movable rod 43 has a groove 48 on its surface, and a sliding rod 410 is engaged in the groove 48. The sliding rod 410 is slidably connected in the limiting seat 49 and in the through plate 411. A convex ring 413 is fixedly connected to the sliding rod 410. The convex ring 413 is elastically connected to the through plate 411 through a second spring 412. When the movable rod 43 slides, it presses the sliding rod 410 downward. The sliding rod 410 drives the convex ring 413 to press the second spring 412. The sliding rod 410 moves into the limiting seat 49. After the movable rod 43 is clamped and positioned, the second spring 412 springs up and causes the sliding rod 410 to engage in the groove 48. The elastic clamping device 4 ensures that the flexible stacked valve will not loosen or move during the processing, thus ensuring processing accuracy and quality.

[0028] Furthermore, to protect the surface quality of the flexible stacked valve and enhance clamping stability, the rotating clamping device 5 specifically includes a linear drive device 51. The linear drive device 51 is fixedly connected to the lower surface of the worktable 2. A hinge rod 52 is fixedly connected to the output end of the linear drive device 51. The end of the hinge rod 52 away from the linear drive device 51 is connected to a hinged rotating plate 53. Through the operation of the linear drive device 51, the output end is driven to pass through the worktable 2, lifting the hinge rod 52 upwards. A rotating wheel 56 is rotatably connected to the rotating plate 53. The hinge rod 52 drives the rotating plate 53 forward, bringing the rotating wheel 56 into contact with the flexible stacked valve. The rotating wheel 56 can reduce the friction between the rotating wheel and the valve components. Friction is avoided while ensuring stable pressure is applied to the valve. A hinge plate 54 is rotatably connected to the rotating plate 53, and the hinge plate 54 is rotatably connected to the hinge seat 55. The rotating plate 53 can maintain a stable posture during movement, and through the cooperation of the hinge plate 54 and the hinge seat 55, it can better withstand the reaction force from the flexible stacked valve, ensuring the reliability of the clamping action. The upper surface of the worktable 2 is fixedly connected to the hinge seat 55. Multiple sets of rotating clamping devices 5 are provided. The rotating clamping devices 5 avoid scratches or wear on the valve surface that may be caused by rigid contact, which helps to protect the surface quality of the flexible stacked valve, further enhances the stability of clamping, and ensures the positional accuracy of the valve during the processing.

[0029] In this invention, when the flexible stacked valve is placed on the placement platform 3, the motor 42 is turned on. The output shaft of the motor 42 drives the moving rod 43 to move. During the forward movement of the moving rod 43, the fixing ring 46 stretches the first spring 47, causing the first spring 47 to undergo elastic deformation and store elastic potential energy. Simultaneously, the moving rod 43 slides and presses down on the sliding rod 410. The sliding rod 410 drives the convex ring 413 to press the second spring 412, causing the sliding rod 410 to move into the limiting seat 49. After the moving rod 43 clamps and positions the valve, the second spring 412 springs up, causing the sliding rod 410 to engage in the groove 48, completing the clamping operation of the flexible stacked valve. The elastic clamping device 4 ensures that the flexible stacked valve will not loosen or move during processing, maintaining its position. To ensure machining accuracy and quality, while motor 42 is working, linear drive device 51 drives the output end through the worktable 2, raising the hinge rod 52 upward. The hinge rod 52 drives rotating plate 53 forward, and rotating wheel 56 contacts the flexible stacked valve. Rotating wheel 56 can reduce friction between the rotating plate and the valve, while ensuring stable pressure on the valve. During the movement, rotating plate 53, through the cooperation of hinge plate 54 and hinge seat 55, can better withstand the reaction force from the flexible stacked valve, ensuring the reliability of the clamping action, avoiding scratches or wear on the valve surface that may be caused by rigid contact, which helps protect the surface quality of the flexible stacked valve, further enhances the stability of clamping, and ensures the positional accuracy of the valve during the machining process.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
