Description
Technical Field
[0001] This utility model relates to the field of diesel engine technology, and in particular to a diesel engine oil suction pipe support tooling. Background Technology
[0002] A diesel engine fuel suction pipe support fixture is a tool or device specifically designed to support and secure the diesel engine fuel suction pipe. It is typically made of materials such as metal or plastic and is designed to ensure that the fuel suction pipe maintains the correct position and angle during diesel engine operation, preventing damage or leakage caused by vibration, displacement, or other external forces.
[0003] Traditional suction pipe supports often lack uniform clamping force, resulting in uneven stress on the suction pipe during clamping, which may lead to deformation or damage. In addition, traditional suction pipe supports are usually only suitable for suction pipes of specific sizes. When faced with suction pipes of different sizes, their flexibility and adaptability are poor and their versatility is insufficient. Therefore, it is necessary to frequently change or adjust the tooling to adapt to suction pipes of different specifications.
[0004] Therefore, those skilled in the art have provided a diesel engine oil suction pipe support tooling to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a diesel engine oil suction pipe support fixture. By rotating a double-threaded rod, the sliding block and clamping components are adjusted to accommodate oil suction pipes of different sizes. The design of multiple sleeves and connecting rods ensures that the fixing block provides a more uniform and powerful clamping force when holding the oil suction pipe. The multi-point support structure effectively enhances clamping stability, preventing the oil suction pipe from shaking or shifting during processing or installation. The return spring ensures that the fixing block continuously provides a stable clamping force during clamping, and even under external forces, it provides buffering and compensation, ensuring that the clamping force does not weaken, thus guaranteeing the stable position of the oil suction pipe. Furthermore, the return spring ensures that the fixing block automatically returns to its initial position after the clamp is released, further enhancing the fixture's versatility and adaptability. The overall design allows the same fixture to be used for various specifications of oil suction pipes, improving the fixture's efficiency and flexibility.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A diesel engine fuel suction pipe bracket tooling includes a base plate, a bidirectional threaded rod, and multiple fixing blocks. Fixing frames are fixedly connected to the middle of both sides of the upper surface of the base plate. The bidirectional threaded rod is located at the middle of the upper end of the fixing frame. One side of the outer wall of the bidirectional threaded rod is rotatably connected to the outer wall of the fixing frame on the other side. A rotating handle is fixedly connected to the middle of the outer wall of the other side of the bidirectional threaded rod. The other side of the rotating handle passes through the fixing frame to the other side of the fixing frame. Sliding blocks are threadedly connected to both sides of the outer wall of the bidirectional threaded rod. Clamping elements are fixedly connected to the upper ends of the sliding blocks. Connecting plates are fixedly connected to the front and rear ends of the middle of the upper surface of the base plate. Limiting grooves are formed on the outer walls of adjacent ends of the upper part of the connecting plates. Limiting blocks are fixedly connected to the front and rear ends of the lower outer walls of the sliding blocks.
[0008] Through the above technical solution, by rotating the bidirectional threaded rod, the sliding block drives the clamping component to adjust its position, thereby adapting to oil suction pipes of different sizes. In addition, the limiting groove and the limiting block cooperate to achieve limiting protection for the sliding block. This design prevents the sliding block from exceeding the preset range during movement, avoiding possible damage or errors.
[0009] Furthermore, the outer wall of the clamping member is fixedly connected with multiple sleeves. The side of each sleeve near the center of the base plate passes through the clamping member to the side of the clamping member near the center of the base plate. The middle of the front and rear ends of the inner wall of each sleeve is provided with sliding grooves. A connecting rod is provided inside each sleeve. The middle of the front and rear ends of the outer wall of each connecting rod is fixedly connected with sliding plates. A fixing block is fixedly connected to the outer wall of the connecting rod near the center of the base plate. A return spring is fixedly connected to the outer wall of the connecting rod away from the center of the base plate. The return springs are all located inside the sleeves. The side of the return spring away from the center of the base plate is slidably connected to the inner wall of the sleeve away from the center of the base plate.
[0010] Through the above technical solution, the design of multiple sleeves and connecting rods enables the fixing block to provide a more uniform and powerful clamping force when clamping the oil suction pipe. This multi-point support structure effectively enhances the stability of clamping and prevents the oil suction pipe from shaking or shifting during processing or installation. The elasticity of the return spring ensures that the fixing block can continuously provide a stable clamping force during clamping. Even under the action of external force, the spring can play a buffering and compensating role to ensure that the clamping force does not weaken, thereby ensuring the stable position of the oil suction pipe. Furthermore, the setting of the return spring ensures that the fixing block can automatically return to the initial position after the clamping is released. This design allows the fixing block to adapt to oil suction pipes of different diameters, enhancing the versatility and adaptability of the tooling, so that the same tooling can be used for oil suction pipes of various specifications.
[0011] Furthermore, both sides of the lower outer wall of the base plate are fixedly connected to fixing plates, and multiple fixing holes are opened on the upper surface of the fixing plates on the side away from the center of the base plate.
[0012] The above technical solution increases the stability and rigidity of the entire tooling through the design of the fixing plate. This design effectively prevents the tooling from tilting or shaking during operation and ensures the stable support of the oil suction pipe bracket. The fixing holes use bolts or other fasteners to enhance the fixing force between the tooling and the base or other structures, which ensures that the tooling will not shift when subjected to external forces or vibrations.
[0013] Furthermore, the outer wall of the other side of the bidirectional threaded rod is rotatably connected to the outer wall of one side of the fixed frame, and the outer wall of the other side of the rotating rod is rotatably fitted to the inner wall of the middle part of the fixed frame;
[0014] The above technical solution, through the design of the rotary connection, ensures the stability and accuracy of the bidirectional threaded rod and the rotary handle during the adjustment process. This fitting design reduces shaking and offset during rotation and enhances the stability of the entire tooling.
[0015] Furthermore, the outer walls of the limiting blocks are all slidably fitted against the inner walls of the limiting grooves;
[0016] The above technical solution ensures that the limiting block can move and be positioned accurately within the limiting groove through the sliding fit design. This precise limiting function can effectively prevent the oil suction pipe bracket from shifting during processing or installation, thus ensuring the accuracy of the bracket's position.
[0017] Furthermore, the outer wall of the sliding plate is slidably fitted with the inner wall of the sliding groove, and the outer wall of the sleeve on the side away from the center of the bottom plate is slidably fitted with the inner wall of the sleeve.
[0018] The above technical solution reduces errors during the adjustment of the connecting rod and improves the positioning accuracy of the fixing block, thereby ensuring the installation accuracy and stability of the oil suction pipe bracket.
