Description

Technical Field

[0001] The utility model relates to the technical field of chain correction machines, in particular to a left pitch adjustment mechanism of a chain correction machine. Background Art

[0002] In the traditional chain correction machine design, the left pitch adjustment often depends on the operator's skills and experience, and is achieved through manual adjustment or simple mechanical adjustment. These traditional methods have many shortcomings, such as low adjustment accuracy, low efficiency, poor stability, etc. The manual adjustment process is not only time-consuming and labor-intensive, but also difficult to ensure the consistency and accuracy of each adjustment. In addition, the simple mechanical adjustment mechanism may not be able to adapt to the needs of fast and frequent adjustments due to insufficient design precision or material performance limitations, resulting in unstable chain correction quality and affecting the reliability and life of the entire system.

[0003] A Chinese patent discloses a pitch-adjustable chain link (publication number: CN 201597999U) comprising a pin, a bushing mounted on the pin, a chain link base mounted on the bushing, and a guide wheel located below the chain link base and mounted on the pin, wherein one end of the chain link base is a hanging ear structure with a U-shaped groove in the middle, and a laterally adjustable pitch adjustment slider is installed in the middle of the other end, and a longitudinal through hole that can be mounted on the pin is opened on the pitch adjustment slider, but this pitch adjustment mechanism has low automation, low adjustment accuracy, low efficiency, poor stability, etc.; and cannot adapt to the needs of fast and frequent adjustment, resulting in unstable chain correction quality, affecting the reliability and life of the entire system, and therefore a chain correction machine left pitch adjustment mechanism is needed. Utility Model Content

A left pitch adjustment mechanism for a chain correction machine is proposed.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the left pitch adjustment mechanism of a chain correction machine described in the utility model includes an outer shell, and is characterized in that: a cover plate is connected to one side of the outer shell, a main shell is arranged inside the outer shell, a linkage gear is arranged at the center of one side of the main shell, a transmission sprocket is connected to one end of the linkage gear, intermediate gears are meshed on both sides of the linkage gear, T-type screw transmission gears are meshed on both sides of the intermediate gear, and positioning screws are arranged at both ends of the other side of the cover plate to achieve stable and accurate pitch adjustment.

[0006] Preferably, the number of the T-screw transmission gears is 2 and they are arranged correspondingly. A transmission T-screw sleeve is provided at the center of the inner circle of the T-screw transmission gear. The T-screw transmission gear and the transmission T-screw sleeve are arranged concentrically, ensuring the concentricity and movement accuracy of the gear, thereby improving the accuracy of the adjustment process.

[0007] Preferably, the transmission T-screw sleeve passes through the main shell and the cover plate in sequence and is connected with a locking nut. The T-screw transmission gear is positioned through the linkage of the transmission T-screw sleeve and the locking nut. This layout allows the T-screw transmission gear to be accurately positioned through the transmission T-screw sleeve and the locking nut, thereby increasing the reliability of operation and the stability after adjustment.

[0008] Preferably, a pressure sensor top block is provided at the center of the other side of the cover plate, and the pressure sensor top block is associated with the linkage gear. Through the association and cooperation between the pressure sensor top block and the linkage gear, the pressure sensor top block is convenient for transmitting pressure to the matching pressure sensor, so that the tension of the chain can be monitored and adjusted in real time, ensuring uniform force on the chain during the correction process, thereby improving the correction quality and efficiency.

[0009] Preferably, the linkage gear, intermediate gear and T-type screw transmission gear are all made of high-strength aluminum alloy, which not only provides good mechanical strength, but also effectively reduces the overall weight, making the mechanism operate more efficiently and consume less energy.

[0010] Preferably, the main shell and the outer shell are both made of carbon fiber reinforced plastic, which provides excellent structural stability and corrosion resistance, while greatly reducing the weight of the mechanism, thus ensuring the durability and reliability of the chain correction machine.

[0011] The utility model is beneficial in that:

[0012] The utility model has a high degree of automation. The left pitch adjustment mechanism is mainly used to adjust the position of the left drag plate to match the length position of chains of different specifications, thereby enhancing the applicability and flexibility of the equipment. The left drag plate can be adjusted slowly left and right by controlling the steering of the motor. The power is controlled by the motor, linkage gear, intermediate gear and T-type screw transmission gear to achieve the purpose of deceleration and force increase, thereby realizing precise control of the chain pitch and ensuring that each adjustment meets high-precision requirements. The correction accuracy is significantly improved, and the use of high-strength and wear-resistant materials ensures stability and reliability in long-term operation, thereby reducing long-term operating costs.
