Description

Technical Field

[0001] This utility model relates to the field of VTG ring processing technology, specifically a multi-station hydraulic clamp for VTG rings. Background Technology

[0002] VTG usually refers to Variable Geometry Turbocharging technology, which is an important innovation in the field of automotive engines. Its core is to dynamically adjust the turbine blade angle to change the cross-sectional area of ​​the exhaust gas flow. At low speeds, the flow channel is reduced to increase the airflow speed, reduce turbo lag, and enable the engine to output peak torque. VTG is now widely used in diesel and high-end gasoline engines. During the VTG processing, hydraulic clamps are required to hold the VTG components.

[0003] The hydraulic clamp for VTG components cannot clamp multiple VTG components at once, making it difficult to meet the needs of mass production. Each processing operation requires positioning and clamping one by one, which not only prolongs the production cycle but also increases labor intensity due to frequent manual operation. Furthermore, positioning deviations are prone to occur during clamping, affecting the processing accuracy of VTG components.

[0004] Therefore, we propose a multi-station hydraulic clamp for VTG rings. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-station hydraulic clamp for VTG rings, thereby solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station hydraulic clamp for a VTG ring, comprising a main fixing plate, a side VTG clamping assembly, and a middle VTG clamping assembly, as well as a snap-fit ​​post that is inserted and installed into the main fixing plate. A positioning pin is inserted and installed at the top of the snap-fit ​​post, and a positioning head is fixedly installed at the end of the positioning pin away from the main fixing plate. A VTG ring body is sleeved on the outer side of the positioning pin. Lifting rings are fixedly installed on both sides of the top of the main fixing plate. A side cylinder insertion hole adapted to the side VTG clamping assembly is opened at the top of the main fixing plate, and a middle cylinder insertion hole adapted to the middle VTG clamping assembly is opened at the top of the main fixing plate. The number of positioning pins is twice that of the middle VTG clamping assembly, the number of the side VTG clamping assembly is twice that of the positioning pins, and the number of the snap-fit ​​posts, positioning pins, positioning heads, and VTG ring bodies are the same.

[0007] Preferably, the side VTG clamping assembly includes a side hydraulic cylinder, which is inserted into a side cylinder insertion hole. A cylinder fixing plate is provided on the outside of the side hydraulic cylinder, and the cylinder fixing plate is fixedly connected to the main fixing plate by bolts. A support block is fixedly installed on the outside of the side hydraulic cylinder. A first rotating rod and a second rotating rod are provided at both ends of the support block. A connecting piece is connected to the outside of the support block through the first rotating rod and the second rotating rod. A third rotating rod is rotatably installed on the movable end of the side hydraulic cylinder. A clamping rod is provided between the second rotating rod and the third rotating rod. A side rubber clamp is provided at the end of the clamping rod away from the third rotating rod.

[0008] Preferably, there are two identical connecting pieces, which are symmetrically distributed on both sides of the support block, and the axis of the second rotating rod and the central axis of the clamping rod are on the same straight line.

[0009] Through the above technical solution, the side hydraulic cylinder pushes one end of the clamping rod upward through the third rotating rod, and the clamping rod will rotate around the second rotating rod. The side rubber clamp at the end of the clamping rod away from the third rotating rod can press the VTG ring body, thereby realizing the lateral pressing of the VTG ring body.

[0010] Preferably, the intermediate VTG clamping assembly includes an intermediate hydraulic cylinder, which is plugged into the intermediate cylinder insertion hole and fastened to the main fixing plate by bolts. A movable rod is fixedly installed on the movable end of the intermediate hydraulic cylinder, and a pressure sleeve is sleeved on the end of the movable rod away from the intermediate hydraulic cylinder. A locking pin is provided at the connection between the pressure sleeve and the movable rod, and an intermediate rubber chuck is fixedly installed on the side of the pressure sleeve near the positioning pin.

[0011] Preferably, the number of the intermediate rubber clamps is twice that of the pressure sleeve, and the pressure sleeve and the intermediate rubber clamps together form an "↑" shaped structure.

[0012] Through the above technical solution, the hydraulic cylinder drives the rubber clamp to move downward through the moving rod and the pressure sleeve, and the two identical rubber clamps press against the adjacent VTG ring bodies.

[0013] Preferably, the four central VTG clamping components are evenly distributed on the horizontal axis of the main fixing plate, and one central VTG clamping component and the four side VTG clamping components together form an "X" shaped structure.

[0014] The above technical solution, through the design of a set of four side VTG clamping components and one middle VTG clamping component, can press the VTG ring body located on both sides of the middle VTG clamping component to ensure that it will not loosen, thus facilitating subsequent processing operations.

[0015] Compared with the prior art, this utility model provides a multi-station hydraulic clamp for VTG rings, which has the following advantages: This multi-station hydraulic clamp for VTG rings can simultaneously clamp and fix multiple VTG ring bodies through its multi-station design, significantly reducing the clamping time for a single processing operation and greatly improving batch processing efficiency. It adopts the synergistic effect of the side VTG clamping components and the middle VTG clamping components. The side rubber chucks achieve lateral clamping, while the middle rubber chucks clamp adjacent workpieces longitudinally, forming clamping forces in multiple directions and angles. The "X"-shaped combination structure ensures that each VTG ring body is stably fixed, effectively preventing loosening or displacement during processing and ensuring processing accuracy.

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.

[0019] Example 1: like Figure 1-7 As shown, the present invention provides a multi-station hydraulic clamp for VTG rings, including a main fixing plate 1, a side VTG clamping assembly 5 and a middle VTG clamping assembly 6, and a snap-fit ​​post 2 that is inserted and installed with the main fixing plate 1. A positioning pin 3 is inserted and installed at the top of the snap-fit ​​post 2. A positioning head 4 is fixedly installed at the end of the positioning pin 3 away from the main fixing plate 1. A VTG ring body 8 is sleeved on the outside of the positioning pin 3. Lifting rings 7 are fixedly installed on both sides of the top of the main fixing plate 1. A side cylinder insertion hole 10 adapted to the side VTG clamping assembly 5 is opened at the top of the main fixing plate 1. A middle cylinder insertion hole 11 adapted to the middle VTG clamping assembly 6 is opened at the top of the main fixing plate 1. The number of positioning pins 3 is twice that of the middle VTG clamping assembly 6, the number of side VTG clamping assemblies 5 is twice that of the positioning pins 3, and the number of snap-fit ​​posts 2, positioning pins 3, positioning heads 4 and VTG ring bodies 8 are the same.

[0020] Example 2: like Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0021] Specifically, the side VTG clamping assembly 5 includes a side hydraulic cylinder 501, which is inserted into the side cylinder insertion hole 10. A cylinder fixing plate 502 is provided on the outside of the side hydraulic cylinder 501. The cylinder fixing plate 502 is fixedly connected to the main fixing plate 1 by bolts. A support block 503 is fixedly installed on the outside of the side hydraulic cylinder 501. A first rotating rod 504 and a second rotating rod 506 are provided at both ends of the support block 503. A connecting piece 505 is connected to the outside of the support block 503 through the first rotating rod 504 and the second rotating rod 506. A third rotating rod 507 is rotatably installed on the movable end of the side hydraulic cylinder 501. A clamping rod 508 is provided between the second rotating rod 506 and the third rotating rod 507. A side rubber clamp 509 is provided at the end of the clamping rod 508 away from the third rotating rod 507.

[0022] Specifically, there are two identical connecting pieces 505, which are symmetrically distributed on both sides of the support block 503. The axis of the second rotating rod 506 is on the same straight line as the central axis of the clamping rod 508.

[0023] The advantage is that the side hydraulic cylinder 501 pushes one end of the clamping rod 508 upward through the third rotating rod 507, and the clamping rod 508 will rotate around the second rotating rod 506. The side rubber clamp 509 of the clamping rod 508 away from the third rotating rod 507 can press the VTG ring body 8, thereby realizing the lateral pressing of the VTG ring body 8.

[0024] Example 3: like Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0025] Specifically, the VTG clamping assembly 6 includes a hydraulic cylinder 601, which is plugged into the cylinder insertion hole 11 and fastened to the main fixing plate 1 by bolts. A movable rod 602 is fixedly installed on the movable end of the hydraulic cylinder 601. A pressure sleeve 603 is sleeved on the end of the movable rod 602 away from the hydraulic cylinder 601. A locking pin 605 is provided at the connection between the pressure sleeve 603 and the movable rod 602. A rubber chuck 604 is fixedly installed on the side of the pressure sleeve 603 near the positioning pin 3.

[0026] Specifically, the number of intermediate rubber clamps 604 is twice that of the pressure sleeve 603, and the pressure sleeve 603 and intermediate rubber clamps 604 together form an "↑" shaped structure. The advantage is that the intermediate hydraulic cylinder 601 drives the intermediate rubber clamps 604 to move downward through the movable rod 602 and the pressure sleeve 603, and the two identical intermediate rubber clamps 604 press against the adjacent VTG ring bodies 8.

[0027] Specifically, four central VTG clamping components 6 are evenly distributed along the horizontal axis of the main fixing plate 1. The central VTG clamping component 6 and the four side VTG clamping components 5 together form an "X"-shaped structure. The advantage is that the design of a set of four side VTG clamping components 5 and one central VTG clamping component 6 can effectively clamp the VTG ring bodies 8 located on both sides of the central VTG clamping component 6, ensuring they do not loosen and facilitating subsequent processing operations. Working principle: During use, the operator places multiple VTG ring bodies 8 on top of multiple positioning pins 3 and positioning heads 4 in sequence. Using the lifting rings 7 on both sides of the top of the main fixing plate 1, the main fixing plate 1 is hoisted to the required position. Then, the hydraulic clamp is connected through the cylinder distribution valve and the hydraulic clamp is started. At this time, the side hydraulic cylinder 501 pushes one end of the clamping rod 508 upward through the third rotating rod 507. The clamping rod 508 will rotate around the second rotating rod 506. The side rubber clamp 509 at the end of the clamping rod 508 away from the third rotating rod 507 can press the VTG ring body 8, thereby achieving lateral pressing of the VTG ring body 8. The middle hydraulic cylinder 601 drives the middle rubber clamp 604 downward through the movable rod 602 and the pressure sleeve 603. Two identical middle rubber clamps 604 press the adjacent VTG ring bodies 8. The overall design is reasonable, and multiple VTG ring bodies 8 can be clamped at one time, which greatly improves the processing efficiency.
