In this embodiment, the chuck 301 has seted up the hole of stepping down corresponding to the distribution axle center of clamping jaw 302, linear drive mechanism is provided with a transmission pole 304 that passes the hole of stepping down and linear electric motor 306 that control transmission pole 304 followed clamping jaw 302 distribution axle center motion, slider 303 is installed and is penetrated the one end in the hole of stepping down in transmission pole 304. Therefore, the structure of the driving slide block 303 penetrating from the inside of the chuck 301 is more compact, and the structure volume can be reduced.

In order to achieve a natural opening of the clamping jaws 302, the clamping chuck 301 and the clamping jaws 302 can be made entirely of wear-resistant rubber, while the sliding blocks 303 act on the outer sides of the clamping jaws 302. Thus, when the slider 303 is moved toward the open end of the jaw 302, it pushes the outer side of the jaw 302 to close it.

Considering that the nozzle 100 needs to be rotated to be screwed into the valve body 110 after being clamped, if the integral rotation linear driving mechanism is easy to affect the transmission stability, further, the transmission rod 304 in this embodiment is provided with a connecting rod 305 at one end near the linear motor 306, one end of the connecting rod 305 is fixedly connected with the output shaft of the linear motor 306, and the other end is rotatably connected with the transmission rod 304 through a bearing, between which the connecting rod 305 is inserted into the transmission rod 304 and fixed through a bearing, or vice versa, so as to be rotatable therebetween.

Therefore, the clamping jaw 302 can be effectively protected by arranging the adjusting sleeve 308, and the service life is prolonged. And the sliding block 303 is extruded and pushed by the adjusting sleeve 308, so that the stability is stronger, the work is more reliable, and compared with a structure that the transmission rod 304 is fixedly connected with the sliding block 303 to directly push the sliding block 303 to extrude the clamping jaw 302, the shearing force applied to the transmission rod 304 can be eliminated, and the service life is prolonged.

As shown in fig. 14, since the nozzle pipe segment 103 has a certain length, in order to increase the clamping force of the clamping device, a first clamping portion adapted to the nozzle pipe segment 103 is provided inside the clamping jaw 302, and a second clamping portion is provided at one end of the slider 303 close to the distribution axis of the clamping jaw 302. The size of the second clamping part is designed to meet the requirement that when the first clamping part clamps the nozzle circular pipe section 103, the second clamping part is attached to clamp the nozzle circular pipe section 103, so that the second clamping part is used for matching with the first clamping part to clamp the nozzle circular pipe section 103. Therefore, the part of the nozzle pipe section 103 close to the hexagonal nut structure 102 is clamped by the first clamping part, and the rear end of the nozzle pipe section is fixed by the second clamping part, so that the clamping effect is better, and the nozzle 100 can be conveniently screwed into the valve body 110 subsequently.

The operation of the nozzle assembly apparatus 3 having the above-described structure is as follows:

in the initial state, the linear motor 306 pulls the sliding block 303 to move away from the opening direction of the clamping jaw 302 through the connecting rod 305 and the transmission rod 304, the clamping jaw 302 gradually opens outwards under the action of the material property of the clamping jaw 302 and pushes the sliding block 303 to slide outwards in the channel on the transmission rod 304, and at the moment, the nozzle 100 can be fed from the outside;

when the nozzle pipe section 103 is inserted into the clamping jaw 302, the linear motor 306 pushes the sliding block 303 to move towards the opening direction of the clamping jaw 302 through the connecting rod 305 and the transmission rod 304, and under the action of the adjusting sleeve 308, the sliding block 303 slides inwards in the channel on the transmission rod 304 at the same time, so that the clamping jaw 302 is pushed to be folded, until the first clamping part and the second clamping part clamp and fix the nozzle pipe section 103.

And further a push cylinder may be provided to adjust the horizontal position of the rotary mount 503. The three-jaw chuck 502 is adapted to the hex nut arrangement 102 of the nozzle 100 or to the threaded connection 101 thereof so as to expose the nozzle barrel 103 when gripping the nozzle 100.

Thus, in operation, the three-jaw chuck 502 is controlled by the rotary mounting block 503 to rotate to the output end of the horizontally aligned nozzle feed vibratory plate 501 to pick up one nozzle 100, and then rotated and transported to a predetermined position to allow the holding device to pick up the nozzle 100.
