Description

Technical Field

[0001] This utility model belongs to the technical field of ship component processing equipment, and in particular relates to a clamping device for ship rod-shaped support components. Background Technology

[0002] In shipbuilding, rod-shaped support components are crucial structural parts, and their machining accuracy and quality directly affect the overall performance and safety of the ship. During machining, the stable clamping of these rod-shaped support components is a key step in ensuring smooth processing.

[0003] Existing clamping devices are mainly divided into two categories: manual clamping and pneumatic clamping. Manual clamping relies on tightening bolts to fix components, which not only has low operating efficiency but also makes it difficult to control the clamping force evenly, easily leading to component deformation or positioning misalignment. It is especially unsuitable for batch processing of long rod-shaped components. Although pneumatic clamping solves the efficiency problem, most devices can only clamp rod-shaped components of a specific diameter. When changing to components of different specifications, the clamping blocks need to be disassembled and replaced, which is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a clamping device for ship rod-shaped support components, which aims to solve the problems of low operating efficiency and poor adaptability of existing clamping devices.

[0005] The present invention adopts the following technical solution:

[0006] The clamping device includes a machine base with a movable carrier. The carrier has a fixed seat and a rotating assembly. A rotating shaft is rotatably mounted inside the fixed seat. The rotating assembly drives the rotating shaft to rotate. The front end of the rotating shaft has a connector with a notch. A top post is located in the center of the notch facing forward. Hands are rotatably mounted on both sides of the top post inside the notch. The front end of each hand has a clamping block secured by a locking screw. The inner sides of the two clamping blocks share a circular groove. Fixed posts are located on both sides of the rotating shaft and on the left and right hand clamps. Tension springs are installed between the fixed posts on the same side. The rotating shaft has a clamping assembly for driving the hand clamps to rotate synchronously.

[0007] Furthermore, the clamping assembly includes a sleeve, the tail of which is formed with a push groove, a push frame is rotatably mounted on the fixed base, a pair of left and right push wheels are rotatably mounted on the push frame, and the push wheels are located in the push groove, and a push cylinder is also rotatably mounted on the fixed base, the drive shaft of the push cylinder being rotatably connected to the top of the push frame.

[0008] Furthermore, the sleeve has a limiting groove, and the rotating shaft is provided with a limiting guide post, which is located in the limiting groove.

[0009] Furthermore, the tail end of the rotating shaft is provided with a driven wheel, the carrier is provided with a rotary motor, the drive shaft of the rotary motor is provided with a driving wheel, and the driving wheel and the driven wheel are provided with belts.

[0010] Furthermore, the side wall of the sleeve has an oblong groove corresponding to the tension spring.

[0011] The beneficial effects of this utility model are:

[0012] 1. This device drives the clamping hand to rotate synchronously through the clamping assembly, thereby clamping the rod-shaped support components of the ship. The clamping hand is subjected to uniform force during rotation, which can ensure that the components are stably clamped, effectively avoiding the components from shifting or shaking during processing, and improving processing accuracy.

[0013] 2. The clamping block is connected to the gripper by locking screws. The appropriate clamping block can be replaced according to different specifications of rod-shaped components, eliminating the need for frequent replacement of clamping parts, which greatly improves processing efficiency and reduces operating costs.

[0018] To make the objectives, technical solutions, and advantages of this utility model patent 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 scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-4As shown, the clamping device includes a machine base 1, on which a carrier 2 that can move back and forth is provided. The carrier 2 is provided with a fixed seat 3 and a rotating assembly. A rotating shaft 4 is rotatably provided inside the fixed seat 3. The rotating assembly drives the rotating shaft to rotate. A connector 5 is provided at the front end of the rotating shaft 4. A notch 6 is opened at the front end of the connector 5. A top post 7 is provided in the middle of the notch 6 facing forward. Handles 8 are rotatably provided on both sides of the top post inside the notch 6. A clamping block 10 is provided at the front end of the handles 8 through a locking screw 9. A circular groove 11 is opened on the inner side of the two clamping blocks 10. Fixed posts 12 are provided on both sides of the rotating shaft 4 and on the left and right handles. A tension spring 13 is provided between the fixed posts 12 on the same side. A clamping assembly for driving the handles to rotate synchronously is provided on the rotating shaft 4.

[0022] Figure 1 In the machine, the machine base 1 is provided with a pair of slide rails 14, the carrier 2 is slidably mounted on the slide rails 14, the machine base 1 is provided with a lead screw 15 rotatably located between the slide rails, the lead screw 15 is fitted with a thread sleeve (covered in the figure) and the thread sleeve is connected to the carrier 2, the machine base 1 is provided with a moving motor 17, and the drive shaft of the moving motor 17 is connected to the lead screw 15.

[0023] When using this device, the carrier is positioned at the loading position with the left and right grippers open. First, the ship-shaped support component to be processed is moved horizontally towards the top column, so that one end of the component rests against the top column. Then, the clamping assembly drives the left and right grippers to rotate inward synchronously, causing the two clamping blocks to gradually approach and clamp the component through the circular groove. Subsequently, the moving motor starts working, driving the lead screw to rotate. The lead screw drives the lead sleeve to move along the length of the lead screw, thereby causing the carrier to move back and forth on the slide rail, adjusting the component to the appropriate processing position.

[0024] In practice, by replacing different clamping blocks, and with the inner grooves of the two clamping blocks adapting to different diameters of ship rod-shaped support components, frequent replacement of clamping parts is eliminated, greatly improving processing efficiency and reducing operating costs.

[0025] As a preferred structure, such as Figure 2-3 The clamping assembly includes a sleeve 18, the tail of which is formed with a push groove 19. A push frame 20 is rotatably mounted on the fixed base 3. A pair of push wheels 21 are rotatably mounted on the push frame 20, and the push wheels 21 are located in the push groove 20. A push cylinder 23 is also rotatably mounted on the fixed base 3. The drive shaft of the push cylinder 23 is rotatably connected to the top of the push frame 20.

[0026] In this structure, the pusher frame is U-shaped with its opening facing downwards. When the clamping assembly drives the left and right grippers to clamp the component, the drive shaft of the pusher cylinder first pushes the pusher frame to rotate forward, the pusher wheel moves within the pusher groove, and pushes the sleeve forward on the rotating shaft. The front end of the sleeve has an inner conical surface, which pushes the grippers to rotate inwards, causing the two clamping blocks to gradually approach and clamp the component. During this process, the tension spring deforms.

[0027] After machining is completed, the jacking cylinder drives the jacking frame to rotate backward. Driven by the jacking wheel, the sleeve moves backward and away from the gripper. At the same time, under the action of the tension spring, the gripper rotates in the opposite direction, causing the two clamping blocks to gradually loosen and the machined component to be removed.

[0028] In this structure, such as Figure 4 The sleeve 18 has a limiting groove 24, and the rotating shaft 4 is provided with a limiting guide post 25, which is located within the limiting groove. Due to the cooperative arrangement of the limiting groove and the limiting guide post, the movement of the sleeve on the rotating shaft is guided and limited, ensuring that the sleeve always moves along the axial direction of the rotating shaft and preventing deviation during movement. This ensures the stability and reliability of the clamping assembly's drive to the gripper, further improving the clamping accuracy of the clamping device.

[0029] Combination Figure 3 The tail of the rotating shaft 4 is provided with a driven wheel 26, the carrier 2 is provided with a rotary motor 27, the drive shaft of the rotary motor is provided with a driving wheel 28, and the driving wheel 28 and the driven wheel 26 are provided with belts 29.

[0030] When processing the components, a rotary motor can drive the drive wheel to rotate, which in turn drives the driven wheel to rotate via a belt, thereby driving the rotating shaft to rotate and achieving rotational drive of the clamped ship rod-shaped support components.

[0031] in addition, Figure 4 In this design, the side wall of the sleeve 18 has an oblong groove 30 corresponding to the tension spring. The oblong groove provides ample room for the tension spring to move, preventing interference between the tension spring and the side wall of the sleeve during sleeve movement, ensuring that the tension spring can function properly and guaranteeing the stable reset of the gripper.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
