[0038] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, proposes

[0039] A device for cleaning residues on the broken surfaces, wherein a connecting rod is broken into a head end 1 and a connecting rod end 2, wherein the head end 1 and the connecting rod end 2 each have two broken surfaces, and two broken intervals 3 are formed between the two broken surfaces of the head end 1 and the two broken surfaces of the connecting rod end 2. The cleaning device is used for cleaning residues on the broken surfaces, and comprises a base 4, a support platform 5 disposed on the base 4, a clamping assembly 6, the clamping assembly 6 being disposed on the support platform 5 and being used for clamping the connecting rod, a moving part 7 being movably disposed on the support platform 5 and moving close to or away from the broken interval 3 after movement, and a negative pressure suction head 20 being disposed on the moving part 7, and passing through the broken interval 3 after following the movement of the moving part 7, and sucking away the residues on the broken surfaces.

[0040] In this embodiment, a base 4 is designed, and the device is based on a stable base 4 to provide basic support, and a support table 5 is installed thereon to ensure a stable operating environment for the entire device. The precisely designed clamping assembly 6 is located on the support table 5, and is specifically used to firmly clamp the connecting rod to ensure that the connecting rod is in a stable position and does not shift during the cleaning process. The flexible moving part 7 is designed on the support table 5, and can be close to or away from the expansion and break interval 3, and can be adjusted as needed to increase the flexibility of operation and make the cleaning closer to the expansion section. The core negative pressure suction head 20 is integrated on the moving part 7, and moves with the moving part 7 to penetrate into the expansion and break interval 3. Through the negative pressure effect, the residue on the expansion section is directly sucked and cleaned, so as to achieve accurate and efficient suction of the residue, reduce manual intervention, and improve cleaning efficiency. In summary, the expansion section residue cleaning device forms an integrated and efficient cleaning system through the synergistic effect of the base 4, the support table 5, the clamping assembly 6, the moving part 7, the negative pressure suction head 20, etc., especially for the expansion section residue treatment, which embodies the application of modern cleaning technology of automation, precision and efficiency.

[0041] Compared with the prior art device for cleaning the residue on the expanded section, the clamping assembly 6 breaks the connecting rod into the head end 1 and the connecting rod end 2 during operation, and simultaneously clamps the head end 1 and the connecting rod end 2, thereby avoiding the steps of moving the head end 1 and the connecting rod end 2 after breaking the connecting rod and then re-fixing them, and then cleaning them after fixing, thereby reducing the labor intensity of the operators, and also reducing the use of the connecting rod moving equipment, thus saving production costs. The design of the negative pressure hood 8 is compared with the prior art. The prior art uses a blowing method, which causes the residue on the expanded section to separate from the expanded section and accumulate in the expanded interval 3. When the head end 1 and the connecting rod end 2 are assembled, the residue may re-enter the expanded section. The negative pressure hood 8 uses an adsorption method, which prevents the residue on the expanded section from falling back into the expanded interval 3, thereby improving the cleaning effect of the equipment on the residue on the expanded section.

[0042] Furthermore, it also includes an ultrasonic vibrator 14, which is movably set on the support platform 5 and moves close to the connecting rod. The ultrasonic vibrator 14 has a variable amplitude rod 15 and a nylon knocking piece 16. The end of the nylon knocking piece 16 and the variable amplitude rod 15 are used to abut against the connecting rod.

[0043] In this embodiment, the ultrasonic vibrator 14 is installed on the support platform 5 and is designed to be movable. It can be driven by an electric cylinder or other driving equipment to move, and can be flexibly close to the connecting rod working area, which means that the ultrasonic energy can directly act near the bulging section of the connecting rod, and effectively loosen the slag by using the high-frequency characteristics of ultrasonic vibration. The ultrasonic vibrator 14 is equipped with a horn 15, and its end is in direct contact with the connecting rod through a nylon knocking piece 16. The nylon knocking piece 16 is designed to enhance the vibration transmission efficiency. Through the ultrasonic vibration of the horn 15, the nylon knocking piece 16 accurately transmits energy to the connecting rod, so that the slag is more thoroughly loosened. The combination of the nylon knocking piece 16 and the horn 15, through ultrasonic vibration, forms a targeted knocking on the connecting rod, effectively vibrating the slag, especially for stubborn objects that are difficult to clean. Through high-frequency vibration and knocking loosening, it is easier to be adsorbed or brushed out by negative pressure, thereby improving the cleaning efficiency. The design of the nylon striking piece 16 takes into account the protection of the connecting rod and avoids direct hard knocking damage. The nylon striking piece 16 acts as a buffer, which not only transmits energy but also protects the connecting rod, ensuring that the connecting rod is not damaged. At the same time, the vibration is accurately transmitted, reflecting the balance between cleaning and protection. In summary, the innovative design of the ultrasonic vibrator 14 and the nylon striking piece 16 not only enhances the efficiency of vibration cleaning, but also ensures the protection of the connecting rod, and realizes more precise and powerful cleaning of the expanded section residue, which is a major innovation of the device technology.

[0044] Furthermore, the clamping assembly 6 includes a support platform 5, and the first clamping member 601 and the second clamping member 602 are both movably set on the support platform 5. The first clamping member 601 and the second clamping member 602 are respectively set 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 or cancel the abutment with one side of the connecting rod end 2 of the connecting rod. The third clamping member 603 and the fourth clamping member 604 are movably set 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 or cancel the abutment with the other side of the head end 1 of the connecting rod.

[0045] In this embodiment, the clamping assembly 6 is composed of four parts, namely the first clamping member 601, the second clamping member 602, the third clamping member 603 and the fourth clamping member 604, which can be movably arranged on the support platform 5, arranged on both sides of the support platform 5, forming a double-end clamping layout. The first clamping member 601 and the second clamping member 602 are located on one side of the support platform 5, and are connected to one end of the head end 1 of the connecting rod; while the third clamping member 603 and the fourth clamping member 604 are on the other side of the support platform 5, corresponding to the other side of the head end 1 of the connecting rod. Such a layout allows the connecting rod to be accurately clamped and kept stable at any end. The movement of the clamping member is driven by a hydraulic device. The design of abutment and cancellation of abutment after movement indicates that the clamping member can be flexibly adjusted, and can contact or release with the head end 1 of the connecting rod according to the cleaning requirements, which is convenient for the loading and unloading and cleaning operations of the connecting rod, and improves the flexibility and efficiency of the operation. The support platform 5 becomes a stable platform for the clamping parts, ensuring the stability of the entire device and the accuracy of operation. In summary, the double-end clamping design of the clamping assembly 6 not only strengthens the stability of the connecting rod, but also improves the flexibility of operation, demonstrating the high efficiency and precise control of the device, which is another innovation in the design of the expanded section cleaning device.

[0046] 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.

[0047] 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 20 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 design not only fits the connecting rod, but also reduces direct hard friction, reduces the risk of possible damage to the connecting rod, protects the connecting rod surface, extends the service life, improves the scope of application of the device, and has better compatibility 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.

[0048] Furthermore, the third clamping member 603 and the fourth clamping member 604 both have a planar clamping portion 606. After the third clamping member 603 and the fourth clamping member 604 move, the planar clamping portion 606 abuts against or cancels the abutment with the plane of the connecting rod end 2. The arc-shaped giving way portion 607 is located on one side of the planar clamping portion 606 and is connected to the planar clamping portion 606. The side clamping portion 608 is located on 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 clamping portion 608 abuts against the side surface of the connecting rod end 2 close to the head end 1.

[0049] 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.

[0050] Furthermore, it also includes an expanding head, which is used to expand the mounting hole of the connecting rod. The expanding head includes a first expanding sleeve 17 and a second expanding sleeve 18. The first expanding sleeve 17 and the second expanding sleeve 18 are both movably set on the support platform 5. After the first expanding sleeve 17 and the second expanding sleeve 18 move, they move closer to each other or away from each other.

[0051] In this embodiment, the expanding head is designed to install the expansion hole of the connecting rod, which is the key interface for the connecting rod fixing and the expansion surface cleaning device, ensuring the stable installation of the connecting rod. The expanding head includes a first expanding sleeve 17 and a second expanding sleeve 18, both of which can be movably set on the support platform 5, realizing the dynamic adjustment function of the expanding head, which is the core of the design. After the first expanding sleeve 17 and the second expanding sleeve 18 move, the operation of moving closer or farther away from each other provides adaptive adjustment of the size of the expansion hole of the connecting rod. This not only facilitates the installation of connecting rods of different sizes, but also provides convenience during installation and disassembly, and improves the flexibility of operation. In summary, the expansion sleeve design and double-layer mobility of the expanding head provide a more flexible adjustment scheme for the installation of the connecting rod, optimize the adaptability and ease of operation of the expansion surface cleaning device, and are a major technical improvement in the design of the device, especially suitable for the cleaning needs of connecting rods of different sizes.

[0052] Furthermore, it also includes a sweep frequency vibrator 19 , which is disposed at the bottom of the support platform 5 and acts on the support platform 5 .

[0053] In this embodiment, a sweeping frequency vibrator 19 is added to the device and installed at the bottom of the support platform 5. This design innovatively applies mechanical vibration technology to the support platform 5, thereby improving the dynamic performance of the entire cleaning device. The sweeping frequency vibrator 19 acts on the support platform 5. By adjusting the vibration frequency, it can effectively suppress the small amplitude vibration of the support platform 5 during operation, thereby increasing the overall stability, especially when the negative pressure suction head 20 is working, reducing shaking and ensuring the cleaning accuracy. Through the dynamic adjustment of the sweeping frequency vibrator 19, the support platform 5 can adapt to the vibration feedback under different working conditions, such as the reaction force generated by high-speed suction head cleaning, thereby improving the overall operation efficiency and continuity, and reducing the interruption of the operation or the influence of instability caused by vibration. In summary, the sweeping frequency vibrator 19 acts on the support platform 5. The expanded section cleaning device not only improves the stability of the operation, but also optimizes the efficiency. It is a technical innovation for vibration control and stability improvement in dynamic operation, and enhances the practical performance of the cleaning device.

[0054] Furthermore, the support platform 5 is rotatably arranged on the base 4 , and the axis of rotation is perpendicular to the line connecting the two expansion and breaking intervals 3 , and the two expansion and breaking intervals 3 are respectively located on both sides of the rotation axis of the support platform 5 .

[0055] In this embodiment, the support platform 5 is no longer fixed, but is arranged on the base 4 so that it can rotate. The rotation drive can be driven by a motor or a hydraulic motor or other equipment. This design allows the entire cleaning device to be flexibly adjusted according to the layout of the expanded section, and is more adaptable. When other equipment is damaged, the centrifugal force generated by the high-speed rotation of the support platform 5 can also clean the expanded section, improving the fault tolerance of the equipment. In summary, the innovation of the rotation design of the support platform 5 on the base 4 not only enhances the flexibility of the cleaning device, but also improves the convenience of operation, making the cleaning operation of multiple expanded sections more efficient, which is a major advancement in device design.
