[0014] The beneficial effects of adopting the above technical solution are:

[0015] 1. The exhaust pipe installation bolt and screw sleeve threading device, first, the screw sleeve is inserted into the storage hopper of the material storage and feeding component 1 in the upper screw sleeve mechanism, and then the conveyor belt in the material storage and feeding component 1 conveys the screw sleeve to fall into the vibration plate component 1. Under the vibration action of the vibration plate component 1, the screw sleeve rises to the screw sleeve guide rail component, and is vibrated by the micro-oscillator 1 below it and transported forward to the upper screw sleeve mouth.

[0016] The bolts are loaded into the storage hopper in the storage and feeding component 2 in the upper bolt mechanism, and then the conveyor belt in the storage and feeding component 2 transports the bolts into the vibration disk component 2. Under the vibration action of the vibration disk component 2, the bolts rise to the bolt guide rail component and are vibrated by the micro-oscillator 2 below it and transported forward to the rear end of the threading mechanism.

[0017] When the sensor detects that there is a screw sleeve on the connecting seat at the corresponding position inside the upper screw sleeve opening, the motor in the turntable mechanism drives the turntable through the reducer to step all the connecting seats on it clockwise by an angle, so that the connecting seat containing the screw sleeve rotates clockwise to the front end of the connecting mechanism.

[0018] Then, the bolt passes through the bolt hole in the middle of the vertical plate to reach the lower end of the lifting plate. At this time, the supporting cylinder in the supporting mechanism drives the clamping block 1 to clamp in the middle, so that the supporting parts are inserted from both sides of the lower end of the lifting plate to support the lower end of the nut of the bolt; then the clamping cylinder in the clamping mechanism drives the clamping block 2 to clamp in the middle, so that the clamping block 2 clamps both sides of the nut of the bolt; then cylinder 1 drives the lifting plate to move downward along the limit guide rail through the clamping block, so that the supporting mechanism, cantilever plate and clamping mechanism connected to the lifting plate move downward with the supported and clamped bolt until the limit block connected to the back of the lifting plate contacts the lower end of the U-shaped groove, and the bolt is inserted into the screw sleeve.

[0019] Then, the clamping cylinder in the clamping mechanism drives the clamping block 2 to loosen on both sides, so that the clamping block 2 releases the clamping on both sides of the nut of the bolt; then, the supporting cylinder in the supporting mechanism drives the clamping block 1 to loosen on both sides, so that the supporting parts move outward from both sides of the lower end of the lifting plate, and the supporting parts release the supporting effect on the lower end of the nut of the bolt. At this time, the bolt falls into the screw sleeve under the action of gravity, completing the bolt threading action.

[0020] Then, cylinder 1 drives the lifting plate to move upward along the limit guide rail through the clamping block, so that the supporting mechanism, cantilever plate and 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; in this process, the supporting cylinder in the supporting mechanism drives clamping block 1 to clamp in the middle, so that the supporting parts are inserted from both sides of the lower end of the lifting plate, preparing for the next time to support the lower end of the nut of the bolt entering from the bolt hole.

[0021] When the sensor detects that there is a screw sleeve on the connecting seat at the corresponding position on the inner side of the upper screw sleeve mouth, the motor in the turntable mechanism drives the turntable through the reducer to step an angle clockwise with all the connecting seats on it, so that the connecting seat containing the screw sleeve rotates clockwise to the front end of the connecting mechanism, and the connecting seat containing the screw sleeve and connected with the bolt rotates clockwise to the next workstation.

[0022] When the threading seat rotates clockwise to the position of the screw sleeve removal opening, the second sensor in the screw sleeve removal mechanism first detects whether a bolt is inserted in the screw sleeve. If there is no bolt inserted in the screw sleeve, the piston rod of the second cylinder drives the screw sleeve removal hook and the slider to shrink along the translation guide rail through the block, so that the screw sleeve removal hook hooks the screw sleeve without a bolt in the threading seat out along the screw sleeve removal opening and drops it into the storage box at the lower end; if there is a bolt inserted in the screw sleeve, the motor in the turntable mechanism drives the turntable through the reducer to step an angle clockwise with all the threading seats thereon, so that the threading seat containing the screw sleeve and the bolt inserted rotates clockwise to the discharge port position.

[0023] Then, the piston rod of the discharging cylinder in the discharging mechanism extends out to push out the screw sleeve with the bolt in the connecting seat corresponding to the discharging port position, thereby completing the discharging operation.

[0024] In the exhaust pipe installation bolt and screw sleeve threading device of the present invention, the whole process of the bolt threading into the screw sleeve is completed by the threading mechanism. During the whole threading process, the inner wall of the screw sleeve does not contact the thread of the bolt, and the thread of the bolt will not be worn.

[0025] The exhaust pipe installation bolt and threaded sleeve connecting device of the present invention realizes the whole process from the initial feeding operation of threaded sleeves and bolts, to the connecting operation of bolts into threaded sleeves, to the removing operation of threaded sleeves with bolts missing from the threaded sleeves, and finally to the discharging operation of threaded sleeves with bolts. The device is fully automated and does not require the participation of workers, has low labor intensity and high connecting efficiency.

[0026] 2. The fixed ring includes a large arc ring and a small arc ring. The large arc ring is provided with an upper screw sleeve opening to enable the screw sleeve to enter the connection seat; a sensor 1 is provided above the upper screw sleeve opening to detect whether the screw sleeve is successfully connected to the connection seat; the gap between the right sides of the large arc ring and the small arc ring constitutes a screw sleeve removal opening to enable the screw sleeve removal hook to hook the screw sleeve that is not connected with the bolt in the connection seat along the screw sleeve removal opening and drop it into the storage box at the lower end; the gap between the left sides of the large arc ring and the small arc ring constitutes a discharge opening to enable the screw sleeve connected with the bolt to be pushed out.

[0027] 3. The upper screw sleeve mechanism and the upper bolt mechanism realize the automatic feeding operation of the screw sleeve and the bolt, and the degree of automation is high; the vertical plate is symmetrically provided with limit guide rails to ensure the straight up and down movement of the lifting plate, thereby ensuring the vertical threading operation of the bolt; a bolt hole is provided in the middle of the vertical plate to align with the end of the bolt guide rail assembly; a U-shaped groove is provided at the upper end of the vertical plate; a limit bolt is provided on the top plate, and a limit block is provided on the back of the lifting plate to limit the up and down movement limit of the limit block, so as to avoid the lower end of the bolt touching the bottom and causing damage to the supporting mechanism and the clamping mechanism.

[0058] The specific working method is described below with specific embodiments:

[0059] Embodiment 1:

[0060] The exhaust pipe installation bolt and screw sleeve connection device, first, the screw sleeve is inserted into the storage hopper in the material storage and feeding component 2-1 in the upper screw sleeve mechanism 2, and then the conveyor belt in the material storage and feeding component 2-1 conveys the screw sleeve to fall into the vibration plate component 2-2, and under the vibration of the vibration plate component 2-2, the screw sleeve rises to the screw sleeve guide rail component 2-4, and is vibrated by the micro-oscillator 2-3 below it and transported forward to the upper screw sleeve mouth 12-3.

[0061] The bolts are loaded into the storage hopper in the material storage and feeding component 2 3-1 in the upper bolt mechanism 3, and then the conveyor belt in the material storage and feeding component 2 3-1 transports the bolts into the vibration plate component 2 3-2. Under the vibration action of the vibration plate component 2 3-2, the bolts rise to the bolt guide rail component 3-4, and are vibrated by the micro-oscillator 2 3-3 below it and transported forward to the rear end of the threading mechanism 5.

[0062] When sensor 12-6 detects that there is a screw sleeve on the connecting seat 43 at the corresponding position on the inner side of the upper screw sleeve opening 12-3, the motor 40 in the turntable mechanism 4 drives the turntable 42 through the reducer 41 to step all the connecting seats 43 thereon clockwise by an angle, so that the connecting seat 43 containing the screw sleeve rotates clockwise to the front end of the connecting mechanism 5.

[0063] Then, the bolt passes through the bolt hole 52-2 in the middle of the vertical plate 52 to reach the lower end of the lifting plate 56. At this time, the supporting cylinder 57-1 in the supporting mechanism 57 drives the clamping block 1 57-2 to clamp in the middle, so that the supporting member 57-3 is inserted from both sides of the lower end of the lifting plate 56 to support the lower end of the nut of the bolt; then the clamping cylinder 59-1 in the clamping mechanism 59 drives the clamping block 2 59-2 to clamp in the middle, so that the clamping block 2 59-2 clamps the two sides of the nut of the bolt; then the cylinder 1 55 drives the lifting plate 56 to move downward along the limiting guide rail 52-1 through the clamping block, so that the supporting mechanism 57, the cantilever plate 58 and the clamping mechanism 59 connected to the lifting plate 56 move downward together with the supported and clamped bolt, until the limiting block 56-1 connected to the back of the lifting plate 56 contacts the lower end of the U-shaped groove 52-3, and the bolt is inserted into the screw sleeve.

[0064] Then, the clamping cylinder 59-1 in the clamping mechanism 59 drives the clamping block 59-2 to loosen on both sides, so that the clamping block 59-2 releases the clamping on both sides of the nut of the bolt; then, the supporting cylinder 57-1 in the supporting mechanism 57 drives the clamping block 57-2 to loosen on both sides, so that the supporting member 57-3 moves outward from both sides of the lower end of the lifting plate 56, and the supporting member 57-3 releases the supporting effect on the lower end of the nut of the bolt. At this time, the bolt falls into the screw sleeve under the action of gravity, completing the bolt threading action.

[0065] Then, the cylinder 55 drives the lifting plate 56 to move upward along the limiting guide rail 52-1 through the clamping block, so that the supporting mechanism 57, the cantilever plate 58 and the clamping mechanism 59 connected to the lifting plate 56 move upward together until the limiting block 56-1 connected to the back of the lifting plate 56 contacts the limiting bolt 54-1 on the top plate 54; in this process, the supporting cylinder 57-1 in the supporting mechanism 57 drives the clamping block 57-2 to clamp in the middle, so that the supporting member 57-3 is inserted from both sides of the lower end of the lifting plate 56, preparing for the next time to support the lower end of the nut of the bolt entering from the bolt hole 52-2.

[0066] When the sensor 12-6 detects that there is a screw sleeve on the connecting seat 43 at the corresponding position on the inner side of the upper screw sleeve opening 12-3, the motor 40 in the turntable mechanism 4 drives the turntable 42 through the reducer 41 to step all the connecting seats 43 thereon clockwise by an angle, so that the connecting seat 43 containing the screw sleeve rotates clockwise to the front end of the connecting mechanism 5, and the connecting seat 43 containing the screw sleeve and connected with the bolt rotates clockwise to the next workstation.

[0067] When the threading seat 43 rotates clockwise to the position of the screw sleeve removal opening 12-4, the sensor 2 63-1 in the screw sleeve removal mechanism 6 first detects whether a bolt is threaded in the screw sleeve.
