[0033] Support platform 5,
[0034] The first clamping member 601 and the second clamping member 602 are both movably arranged on the support platform 5. The first clamping member 601 and the second clamping member 602 are respectively arranged at two ends of one side of the support platform 5. After the first clamping member 601 and the second clamping member 602 move, they abut against or cancel the abutment with one side of the big end 1 of the connecting rod.
[0035] The third clamping member 603 and the fourth clamping member 604 are both movably arranged on the support platform 5 and are located on the other side of the support platform 5. After the first clamping member 601 and the second clamping member 602 move, they abut against or cancel the abutment with the other side of the big end 1 of the connecting rod.
[0036] The first expansion sleeve 17 and the second expansion sleeve 18 are both movably arranged on the support platform 5. After the first expansion sleeve 17 and the second expansion sleeve 18 move, they move closer to or farther away from each other. The first expansion sleeve 17 and the second expansion sleeve 18 are located in the connecting rod mounting hole.
[0037] In this embodiment, a support platform 5 is designed. The device is based on the support platform 5. The first, second, third and fourth groups of clamping parts are arranged on both sides of the support platform 5 to form symmetry, ensuring the stable clamping of the connecting rod head end 1, which can be movably connected or released to meet different operation requirements. The movable design of the clamping part provides convenience for cleaning or installing the connecting rod, flexibly adjusts the space, and improves the working efficiency. It also ensures that connecting rods of different specifications can be fixed. The four groups of mounting parts are all driven by the oil cylinder. The first expansion sleeve 17 and the second expansion sleeve 18 are innovatively installed on the support platform 5. By moving closer or farther away from the action, the expansion and tightening of the connecting rod hole and the expansion and breaking are directly controlled. This is the exquisiteness of the device, which ensures the absolute stability of the connecting rod when cleaning the expansion section, avoids unnecessary movement, and is easy to install and disassemble. In summary, the fixing device for cleaning the expansion section of the connecting rod, through the exquisite layout of the support platform 5, the clamping parts and the expansion sleeve, not only ensures the stable fixation of the connecting rod, but also provides dynamic adjustment convenience, improves the cleaning efficiency, and is a major technical innovation for the expansion section cleaning operation.
[0038] Furthermore, the first clamping member 601 and the second clamping member 602 both have an arc-shaped clamping portion 605. After the first clamping member 601 and the second clamping member 602 move, the arc-shaped clamping portion 605 abuts against or cancels the abutment with the head end 1.
[0039] In this embodiment, the arc-shaped clamping portion 605 is incorporated into the design of the first clamping member 601 and the second clamping member 602. This innovative structure not only fits the curved contour of the connecting rod, but also enhances the stability of the fastening by expanding the contact area. During the cleaning process, even when the negative pressure suction head 17 applies force to the connecting rod, the position can be kept stable and the displacement can be reduced. After the first clamping member 601 and the second clamping member 602 move, the arc-shaped clamping portion 605 can flexibly contact or cancel the abutment with the head end 1 of the connecting rod. This design allows for rapid adaptation to the loading and unloading of the connecting rod, and the operation is simple before and after cleaning, without complex adjustments, and improves the overall operating efficiency. The arc-shaped clamping portion 605 is designed to fit the connecting rod while reducing direct hard friction, reducing the risk of possible damage to the connecting rod, protecting the connecting rod surface, extending the service life, and improving the scope of application of the device. It is better compatible with various connecting rod materials. In summary, through the design of the arc-shaped clamping portion 605 of the first clamping member 601 and the second clamping member 602, the expansion section cleaning device is optimized in terms of the fixation, operational convenience and protection of the connecting rod, which is another important improvement in technology and adapts to a wider range of cleaning needs.
[0040] Further, the third clamping member 603 and the fourth clamping member 604 both have
[0041] After the plane pressing part 606, the third clamping member 603 and the fourth clamping member 604 move, the plane pressing part 606 abuts against or cancels the abutment with the plane of the connecting rod end 2.
[0042] The arc-shaped evacuation portion 607 is located on one side of the plane tightening portion 606 and is connected to the plane tightening portion 606.
[0043] The side tightening portion 608 is located at one side of the arc-shaped giving way portion 607 . After the third clamping member 603 and the fourth clamping member 604 move, the side tightening portion 608 abuts against the side surface of the connecting rod end 2 close to the head end 1 .
[0044] In this embodiment, the third clamping member 603 and the fourth clamping member 604 are equipped with a plane tightening portion 606, which, after moving, precisely abuts or cancels the corresponding plane of the connecting rod end 2. This design ensures the stable fixation of the connecting rod, and keeps the correct position even during the cleaning operation to prevent sliding. The added arc-shaped yielding portion 607 is connected to the plane tightening portion 606 and is located on one side. This design provides additional adaptability space for the connecting rod, allowing the shape of the connecting rod to change, so that the device can more widely match different types of connecting rods, and improves versatility. The side tightening portion 608 located on one side of the arc-shaped yielding portion 607, when the third clamping member 603 and the fourth clamping member 604 move, the top of this side will contact the side of the connecting rod head end 1. This design not only stabilizes the connecting rod, but also takes into account the side fixation of the head end 1, ensuring the stability of the entire connecting rod. In summary, through the planar tightening portion 606, the arc-shaped yielding portion 607 and the side top design of the third clamping member 603 and the fourth clamping member 604, the expanded section cleaning device not only optimizes the stable fixation of the connecting rod, but also enhances the comprehensive adaptability to the connecting rod, and is a technical upgrade for the cleaning needs of different connecting rod types.
[0045] Furthermore, the second expansion sleeve 18 has a guiding inclined surface 1801 , and a guiding groove 1802 is formed between the first expansion sleeve 17 and the guiding inclined surface 1801 .
[0046] In this embodiment, the second expansion sleeve 18 is provided with an inclined surface. This design not only increases the tightness of the expansion sleeve and the connecting rod hole, but also provides guidance during installation to ensure correct alignment. The guide groove 1802 formed by the inclined surface between the first expansion sleeve 17 and the second expansion sleeve 18 provides a smooth path for the tightening of the connecting rod. The guidance of the groove reduces obstacles during installation and ensures the accuracy of tightening. In summary, the guide surface and groove design of the second expansion sleeve 18 optimize the tightening process, improve the accuracy and convenience of connecting rod installation, and ensure accurate positioning during tightening. It is another ingenious idea in the design of the device and improves the overall operating efficiency and practicality.
[0047] Furthermore, it also includes
[0048] The bursting member 26 is slidably arranged in the guide groove 1802. The bursting member 26 has a wedge-shaped portion 2601, and the wedge-shaped portion 2601 abuts against the guide slope 1801. After the bursting member 26 slides, it pushes the first expansion sleeve 17 and the second expansion sleeve 18 away from each other. When the bursting member 26 moves, the third clamping member 603 and the fourth clamping member 604 are pushed.
[0049] In this embodiment, the bursting member 26 is located in the guide groove 1802 and can slide. This design allows the bursting member 26 to be dynamically adjusted as needed to provide power for tightening or releasing. The wedge-shaped portion 2601 of the bursting member 26 abuts against the guide slope 1801, utilizing the principle of mechanics. When the bursting member 26 slides, pressure is applied through the wedge-shaped portion 2601 to push the expansion sleeve away, thereby achieving tightening or releasing, and causing the connecting rod to break. When the bursting member 26 moves, it not only pushes the first expansion sleeve 17 and the second expansion sleeve 18 away, but also links the third clamping member 603 and the fourth clamping member 604. This linkage mechanism simplifies the operation. Through the single action of the bursting member 26, the coordinated action of multiple components is achieved, thereby improving efficiency and control flexibility. In summary, the introduction of the bursting member 26 and its linkage mechanism in the connecting rod expansion section cleaning device realizes the control of automatic tightening and releasing, triggers the linkage of multiple components through a single operation, improves the overall response speed and operation convenience, and is another technical upgrade of the device.
[0050] Furthermore, it also includes
[0051] The linear driving member 27 is arranged on the lower side of the support platform 5 to drive the movement of the bursting member 26 .
[0052] In this embodiment, the linear drive 27 is arranged on the lower side of the support platform 5, and a power unit is added to the device, which directly controls the movement of the bursting member 26. This design improves the level of automation. The linear drive 27 indirectly controls the linkage action of the expansion sleeve and the clamping member by driving the movement of the bursting member 26, realizing the automatic operation of the entire device without manual adjustment, improving work efficiency and reducing the difficulty of operation. In summary, the integration of the linear drive 27 not only optimizes the automatic control of the bursting member 26, but also links the action of the entire device, simplifies the operation steps, and improves the intelligence level of the device, which is another improvement in the automatic control of the device.
[0053] Furthermore, a tooth portion 2602 is provided on one side of the bottom of the bursting member 26 , and the output end of the linear driving member 27 is a gear 2701 , and the tooth portion 2602 is meshed with the gear 2701 .
[0054] In this embodiment, a tooth portion 2602 is added to the bottom of the bursting member 26, which is designed to directly connect with the drive system to ensure the accuracy of power transmission, and the meshing of the gear 2701 improves the stability of control. The output end of the linear drive 27 is designed as a gear 2701, which precisely meshes with the tooth portion 2602 of the bursting member 26. This design ensures the direct transmission of power, improves the response speed and efficiency of the device, and reduces power loss. In summary, the introduction of the meshing of the tooth portion 2602 and the gear 2701, and the precise linkage between the linear drive 27 and the bursting member 26, improve the transmission efficiency and control accuracy of the device, the reaction speed, and reduce the operating error. It is an ingenious design of the device in power control and optimizes the performance of the cleaning fixture.
