Description

Technical Field

[0001] This application relates to the field of diesel engine manufacturing and repair, and in particular to a clamping device for diesel engine crosshead pins. Background Technology

[0002] In the manufacturing and repair of diesel engines, the machining accuracy and efficiency of crosshead pins are crucial to the overall performance of the engine. Traditional clamping tools often suffer from problems such as insecure clamping, inconvenient adjustment, and inability to achieve circumferential rotation or dual-station machining, resulting in low machining efficiency and unstable product quality. Therefore, a new type of clamping tool is needed to solve these problems. Utility Model Content

[0003] To address the problems of traditional clamping devices, such as insecure clamping, inconvenient adjustment, inability to achieve circumferential rotation or dual-station machining, which lead to low processing efficiency and unstable product quality, this application provides a clamping device for diesel engine crosshead pins.

[0004] The clamping device for diesel engine crosshead pins provided in this application adopts the following technical solution:

[0005] A clamping device for a diesel engine crosshead pin includes a circular plate. The top surface of the circular plate is provided with a housing. A motor is provided inside the housing. The output end of the motor passes through the housing and extends upward to connect to a rectangular plate. The top surface of the rectangular plate is provided with an inverted concave shell. Both ends of the top surface of the inverted concave shell are provided with sliding openings. Both ends of the sliding openings are provided with sliders. The top surface of the sliders is provided with clamping plates.

[0006] Preferably, both ends of the inner top wall of the inverted concave shell are provided with slide rails, and the slider is slidably connected to the slide rails.

[0007] Preferably, the top surface of the inverted concave shell is provided with an outer shell, and a hydraulic cylinder is provided inside the outer shell. The output end of the hydraulic cylinder passes through the inverted concave shell and extends downward to connect to a crossbar. Both ends of the crossbar are provided with square plates. Each square plate is connected to two connecting rods through two shafts. The two connecting rods are symmetrical about the left and right axes, and the free ends of the two connecting rods are connected to the corresponding sliders through shafts.

[0008] Preferably, the top surface of the circular plate is provided with an annular groove, and both ends of the bottom surface of the rectangular plate are provided with guide rods, the bottom ends of the guide rods being slidably connected to the annular groove.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] 1. The output end of the hydraulic cylinder drives the crossbar and the square plates at both ends to move vertically downward. The downward movement of the square plates is transmitted through two connecting rods and sliders on them to move relative to each other in the horizontal direction of the slide rail. The relative movement of the two sliders drives the relative movement of the clamping plates on their top surface, thereby achieving the clamping and fixing of crosshead pins of different specifications and sizes. The dual-station clamping function improves processing efficiency and product quality.

[0011] 2. The rectangular plate is driven to rotate by the output end of the motor. The rotation of the rectangular plate drives the inverted concave shell to rotate, thereby realizing the circumferential rotation of the crosshead pin. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a clamping device for a diesel engine crosshead pin, referring to... Figure 1 and Figure 3 The device includes a circular plate 1, a housing 2 fixedly mounted on the top surface of the circular plate 1, a motor 16 inside the housing 2, the output end of the motor 16 passing through the housing 2 and extending upward to be fixedly connected to a rectangular plate 4, an annular groove 15 opening on the top surface of the circular plate 1, and guide rods 3 fixedly mounted at both ends of the bottom surface of the rectangular plate 4, the bottom ends of the guide rods 3 being slidably connected to the annular groove 15, the rectangular plate 4 being rotated by the output end of the motor 16, the rotation of the rectangular plate 4 causing the inverted concave shell 5 to rotate, thereby realizing the circumferential rotation of the crosshead pin.

[0018] Reference Figures 1-2A concave shell 5 is fixedly mounted on the top surface of a rectangular plate 4. Slide openings 6 are provided at both ends of the top surface of the concave shell 5. Slider blocks 7 are slidably mounted at both ends inside the slide openings 6. A clamping plate 8 is fixedly mounted on the top surface of the slider 7. Slide rails 10 are fixedly mounted at both ends of the inner top wall of the concave shell 5. The slider 7 is slidably connected to the slide rails 10. An outer shell 9 is located at the center of the top surface of the concave shell 5. A hydraulic cylinder 11 is located inside the outer shell 9. The output end of the hydraulic cylinder 11 passes through the concave shell 5 and extends downwards, fixedly connected to a crossbar 14. Square plates 13 are fixedly mounted at both ends of the crossbar 14. Each square plate 13 is movable via two shafts. The system is connected by two connecting rods 12, which are symmetrical about the left and right axes. The free ends of the two connecting rods 12 are movably connected to the corresponding sliders 7 via shafts. The output end of the hydraulic cylinder 11 drives the crossbar 14 and the square plates 13 at both ends to move vertically downward. The downward movement of the square plates 13 causes the two connecting rods 12 and the sliders 7 on them to move relative to each other in the horizontal direction along the slide rail 10. The relative movement of the two sliders 7 causes the clamping plates 8 on their top surfaces to move relative to each other, thereby clamping and fixing crosshead pins of different specifications and sizes. The dual-station clamping function improves processing efficiency and product quality.

[0019] The implementation principle of a clamping device for diesel engine crosshead pins in this application embodiment is as follows: In use, the output end of the hydraulic cylinder 11 drives the crossbar 14 and the square plates 13 at both ends to move vertically downward. The downward movement of the square plates 13 is transmitted through the two connecting rods 12 and the sliders 7 on them to move relative to each other in the horizontal direction of the slide rail 10. The relative movement of the two sliders 7 drives the clamping plates 8 on their top surfaces to move relative to each other, thereby achieving the clamping and fixing of crosshead pins of different specifications and sizes. The dual-station clamping function improves processing efficiency and product quality. The output end of the motor 16 drives the rectangular plate 4 to rotate. The rotation of the rectangular plate 4 drives the inverted concave shell 5 to rotate, which is used to achieve the circumferential rotation of the crosshead pin.
