The disadvantages of the traditional method include: First, in manual threading, it is impossible to completely prevent the inner wall of the nut sleeve from contacting the thread of the bolt, which easily causes friction between the inner wall of the nut sleeve and the thread of the bolt, resulting in wear of the thread of the bolt; Second, manual threading has a high labor intensity and low threading efficiency. Summary of the Invention

[0003] The present invention provides a threading mechanism on a bolt and nut sleeve threading device for exhaust pipe installation to solve the problems existing in the above background art.

[0004] To achieve the above object, the technical solution adopted by the present invention is: A threading mechanism on a bolt and nut sleeve threading device for exhaust pipe installation, including a machine base bottom plate and a threading mechanism. The threading mechanism is fixedly connected to the machine base bottom plate. The threading mechanism includes a support frame one, a support frame two, a vertical plate, a triangular support plate, a top plate, a cylinder one, a lifting plate, a material supporting mechanism, a cantilever plate, and a clamping mechanism. The support frame one is fixedly connected to the machine base bottom plate. The support frame two is fixedly connected to the support frame one. The vertical plate is fixedly connected to the front end of the support frame two. The triangular support plate is respectively fixedly connected to the upper end of the support frame two and the back of the vertical plate. The top plate is fixedly connected to the top of the vertical plate. The cylinder one is fixedly connected to the top plate. The piston rod of the cylinder one passes through the top plate and is connected to the lifting plate through a clamping block. The lifting plate is slidably connected to the vertical plate.

[0009] The beneficial effects of adopting the above technical solutions are as follows:

[0010] 1. For the threading mechanism on the bolt and nut sleeve threading device for exhaust pipe installation, first, the nut sleeve moves to the front end of the threading mechanism. Then, the bolt passes through the bolt hole in the middle of the vertical plate and reaches the lower end of the lifting plate. At this time, the feeding cylinder in the feeding mechanism drives the clamping block one to clamp towards the middle, so that the feeding piece inserts from both sides of the lower end of the lifting plate to hold the lower end of the bolt nut. Then, the clamping cylinder in the clamping mechanism drives the clamping block two to clamp towards the middle, so that the clamping block two clamps both sides of the bolt nut. Then, cylinder one drives the lifting plate to move downward along the limit guide rail through the clamping block, so that the feeding mechanism, the cantilever plate and the clamping mechanism connected to the lifting plate move downward together with the bolt held and clamped until the limit block connected to the back of the lifting plate contacts the lower end of the U-shaped groove. At this time, the bolt is inserted into the nut sleeve.

[0011] Then, the clamping cylinder in the clamping mechanism drives the clamping block two to loosen towards both sides, so that the clamping block two releases the clamping of both sides of the bolt nut. Then, the feeding cylinder in the feeding mechanism drives the clamping block one to loosen towards both sides, so that the feeding piece moves outward from both sides of the lower end of the lifting plate, and the feeding piece releases the holding of the lower end of the bolt nut. At this time, the bolt falls into the nut sleeve under the action of gravity, completing the bolt threading action.

[0012] Then, cylinder one drives the lifting plate to move upward along the limit guide rail through the clamping block, so that the feeding mechanism, the cantilever plate and the clamping mechanism connected to the lifting plate move upward together until the limit block connected to the back of the lifting plate contacts the limit bolt on the top plate. During this process, the feeding cylinder in the feeding mechanism drives the clamping block one to clamp towards the middle, so that the feeding piece inserts from both sides of the lower end of the lifting plate to prepare for holding the lower end of the bolt nut entering through the bolt hole next time.

[0013] For the threading mechanism on the bolt and nut sleeve threading device for exhaust pipe installation of the present invention, the entire process of threading the bolt into the nut sleeve is completed by the threading mechanism. During the entire threading process, the inner wall of the nut sleeve does not contact the thread of the bolt, and the thread of the bolt will not be worn.

[0014] For the threading mechanism on the bolt and nut sleeve threading device for exhaust pipe installation of the present invention, the operation of threading the bolt into the nut sleeve is fully automated, without the need for workers to participate, with low labor intensity and high threading efficiency.

[0015] 2. The vertical plate is symmetrically provided with limiting guide rails, which ensure that the lifting plate moves straight up and down, thus ensuring the vertical threading operation of the bolt; a bolt passing hole is provided in the middle of the vertical plate to facilitate the bolt to enter the lower end of the lifting plate; a U-shaped groove is provided at the upper end of the vertical plate; a limiting bolt is provided on the top plate, and a limiting block is provided on the back of the lifting plate to limit the upper and lower movement limits of the limiting block and prevent the lower end of the bolt from touching the bottom and causing damage to the material supporting mechanism and the clamping mechanism.
