The top surface of the cover plate 353 and the cover plate 353 are located near the linear vibration feeder 32 (see Figure 6 ) is provided with a connecting groove 3532 connected to the through port 3531, and the connecting groove 3532 is located at the linear vibration feeder 32 (see Figure 6 ) between the discharge end and the through port 3531, the sealing ring passes through the connecting groove 3532 from the linear vibration feeder 32 (see Figure 6 ) is transported to the through opening 3531; and when the sealing ring falls into the through opening 3531, the top surfaces of the plurality of blocks 352 jointly support the sealing ring.

[0070] In this embodiment, there are four card blocks 352, which are evenly distributed inside the base 351. A limiting groove 3511 is opened in the middle of the four sides of the base 351. The card blocks 352 extend into the limiting groove 3511 corresponding to the position. A limiting portion 3521 is integrally formed at one end of each card block 352 away from the through opening 3531; the limiting groove 3511 limits the card block 352 through the limiting portion 3521, so that the card block 352 is elastically connected to the base 351.

The end of the block 352 away from the through-hole 3531 is provided with two symmetrically arranged receiving grooves 3522. An elastic member 3523 is fixedly connected in each receiving groove 3522. The end of the elastic member 3523 away from the receiving groove 3522 is fixedly connected with the block. Therefore, under the connection action of the elastic member 3523, in the initial state, the limiting portion 3521 is engaged with the limiting groove 3511, and the end of the block 352 close to the through-hole 3531 extends into the through-hole 3531, so that when the sealing ring falls into the through-hole 3531, the top surfaces of the four blocks 352 can jointly support the sealing ring; the end of the block 352 close to the through-hole 3531 is set as an arc surface matching the peripheral side of the extension block 3443.

In this embodiment, the lifting member 341 is a cylinder, the clamping member 343 is a finger cylinder, and the elastic member 3523 is a spring.

[0073] The sealing ring is thus transported from the discharge end of the linear vibration feeder 32 to the through port 3531 through the connecting groove 3532, and the top surfaces of the four clamping blocks 352 jointly support the sealing ring; at this time, the telescopic end of the lifting member 341 contracts, and the conversion column 344 is driven to move downward through the clamping member 343. Since the extension block 3443 is in the shape of a truncated cone as a whole, the downwardly moving extension block 3443 passes through the hollow part of the sealing ring, and after the peripheral side of the extension block 3443 abuts against the arc-shaped surfaces of the four clamping blocks 352, the extension block 3443 pushes the clamping block 352 to move in the opposite direction, so that the elastic member 3523 is in a compressed state, thereby putting the sealing ring on the peripheral side of the extension block 3443, and the four clamping blocks 352 jointly clamp the peripheral side of the extension block 3443, and there is a certain distance between the bottom surface of the extension block 3443 and the top surface of the lifting block 361; then, the clamping end of the clamping member 343 is released, waiting for the feeding of the sealing ring feeding component.

At the same time, in order to buffer the lateral movement of the second lateral sliding seat 371, second elastic buffers 3332 are installed at both ends of the supporting seat 333 and below the second lateral pushing member 37. The buffering ends of the two second elastic buffers 3332 are arranged opposite to each other and both face the second lateral sliding seat 371.

[0075] The second vertical sliding component includes a fixed seat 38 vertically mounted on the side of the second transverse sliding seat 371 away from the second transverse sliding block 3711, a second driving member 381 vertically mounted on the top surface of the fixed seat 38, a screw rod 382 fixedly connected to the output end of the second driving member 381, a second vertical sliding seat 383 threadedly connected to the screw rod 382, ​​and a material-removing member arranged on the second vertical sliding seat 383. The cross section of the fixed seat 38 is U-shaped and its opening faces away from the second transverse sliding seat 371; the length direction of the fixed seat 38 is perpendicular to the length direction of the bearing seat 333; the bottom end of the screw rod 382 is rotatably connected to the bottom end of the fixed seat 38. The second vertical slide rails 384 are fixedly connected to both sides of the fixed seat 38 in the length direction, and the screw rod 382 is located between the two second vertical slide rails 384; the second vertical slide rails are fixedly connected to both sides of the second vertical sliding seat 383, and the second vertical slide rails are slidably connected to the second vertical slide rails 384 corresponding to the positions. The cross section of the second vertical sliding seat 383 is L-shaped, and the material picking member is arranged on the horizontal side of the second vertical sliding seat 383 .

[0076] Reference Figure 8 and Fig. 9 The material picking part includes a material picking sleeve 39 vertically installed on the horizontal side bottom surface of the second vertical sliding seat 383, a pushing cylinder 391 vertically installed on the horizontal side top surface of the second vertical sliding seat 383, a fixing plate 392 fixedly connected to the telescopic end of the pushing cylinder 391, a fixing rod 393 fixedly connected to the bottom surface of the fixing plate 392, and a pushing ring 394 fixedly connected to the bottom end of the fixing rod 393; the material picking sleeve 39 is a hollow cylinder with an opening at the bottom, the material picking sleeve 39 is sleeved on the circumferential side of the conversion column 344, and the material picking sleeve 39 is slidably connected to the conversion column 344, and the lower opening of the material picking sleeve 39 abuts against the top surface of the limit ring 3442.

[0077] The telescopic end of the push cylinder 391 is arranged upward, and two fixed rods 393 are arranged. The two fixed rods 393 are respectively fixed vertically on the two ends of the bottom surface of the fixed plate 392, and the telescopic end of the push cylinder 391 is located between the two fixed rods 393; the push ring 394 is sleeved on the peripheral side of the material taking sleeve 39, and the push ring 394 is slidably connected to the material taking sleeve 39. Two symmetrically arranged fixed ears 3941 are fixedly connected to the outer ring side of the push ring 394, and the bottom end of the fixed rod 393 is fixedly connected to the fixed ear 3941 corresponding to the position. In order to enable the fixed rod 393 to slide vertically more smoothly, two symmetrically arranged sliding ears 3831 are fixedly connected to the horizontal side of the second vertical sliding seat 383, and the fixed rod 393 is slidably connected to the sliding ears 3831 corresponding to the position.

[0078] Therefore, when the sealing ring is sleeved on the peripheral side of the extension block 3443, the four clamping blocks 352 jointly clamp the peripheral side of the extension block 3443, and the clamping end of the clamping member 343 releases the conversion column 344, the telescopic end of the second transverse pushing member 37 contracts, driving the material collection sleeve 39 to move away from the turntable 11 until the material collection sleeve 39 is located above the conversion column 344; at this time, the output end of the second driving member 381 drives the screw rod 382 to rotate, so that the second vertical sliding seat 383 drives the material collection sleeve 39 to move downward, The material picking sleeve 39 is sleeved on the circumferential side of the conversion column 344 until the lower opening of the material picking sleeve 39 abuts against the top surface of the limit ring 3442. As the second driving member 381 drives the second vertical sliding seat 383 to continue to move downward, the material picking sleeve 39 drives the extension block 3443 to continue to move downward. In the process of the extension block 3443 moving downward, since the sealing ring is always located on the top surface of the blocking block 352, when the bottom surface of the extension block 3443 abuts against the top surface of the lifting block 361, the sealing ring is sleeved on the circumferential side of the material picking sleeve 39.

[0079] Subsequently, the output end of the second driving member 381 drives the screw rod 382 to rotate in the opposite direction, so that the second vertical sliding seat 383 drives the material picking sleeve 39 to move up and reset. Then, the telescopic end of the second transverse pushing member 37 is extended, and drives the material picking sleeve 39 to move in the direction close to the turntable 11 through the second transverse sliding seat 371 until the material picking sleeve 39 is located above the steering gear valve body on the turntable 11. At this time, the output end of the second driving member 381 drives the material picking sleeve 39 to move downward through the second vertical sliding seat 383 until the material picking sleeve 39 is sleeved on the steering gear valve body at the corresponding position. Then, the pushing cylinder 391 is started, and the telescopic end of the pushing cylinder 391 contracts, driving the pushing ring 394 to move downward through the fixing rod 393, and the pushing ring 394 pushes the sealing ring sleeved on the peripheral side of the material picking sleeve 39 into the mounting groove 01 on the steering gear valve body, completing the automatic assembly of the sealing ring.

[0080] Finally, the telescopic end of the push cylinder 391 is extended to make the push ring 394 move up and reset, and the output end of the second driving member 381 rotates in the opposite direction, so that the second vertical sliding seat 383 drives the material taking sleeve 39 to move up and reset, and the telescopic end of the lifting cylinder 36 drives the lifting block 361 to move up, so that the clamping end of the clamping member 343 corresponds to the position of the clamping groove 3441, and then the clamping end of the clamping member 343 clamps the conversion column 344 through the clamping groove 3441. At the same time, the lifting cylinder 36 drives the lifting block 361 to reset; then, the lifting member 341 The telescopic end of the linear vibrating feeder 32 is extended, driving the clamping piece 343 to move upward, so that the extension block 3443 moves to the top of the through-port 3531, and the clamping block 352 extends into the through-port 3531 under the resetting action of the elastic piece 3523; at this time, the sealing ring located on the discharge end of the linear vibrating feeder 32 can be transported to the through-port 3531 through the connecting groove 3532, and the sealing ring is supported by the top surfaces of the four clamping blocks 352, waiting for the material taking sleeve 39 to continue taking materials, and the cycle is carried out in sequence, completing the feeding of the four sealing rings from bottom to top onto the diverter valve body.

[0081] Reference Fig.12 and Fig.13 In order to enable the turntable 11 to automatically rotate intermittently, the chassis 1 (see Figure 2 ) is mounted on the top surface thereof, and a transmission member is connected to the output end of the third driving member 12.

[0083] The center of the hollow shaft 132 is hollow and has a larger aperture, and this design allows power or transmission media, such as wires, cables, hydraulic pipelines or pneumatic pipelines, to be transmitted through the center of the hollow shaft 132. The large aperture provides more space to accommodate thicker pipelines or multiple pipelines passing through at the same time, increasing the flexibility and practicality of the design.

If the compression amount of the sealing ring is insufficient, extrusion may occur, causing damage or failure of the sealing ring.
