[0023] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0024] See Figure 1-8As shown, this embodiment discloses an assembly device for a valve seat of an automobile coolant system, including a machine platform 100, the surface of which is inclined, and a valve core seat clamping assembly 200 and three sets of sliding plug-in assemblies 300 are provided on the machine platform 100, and the three sets of sliding plug-in assemblies 300 are arranged around the valve core seat clamping assembly 200.

[0025] The valve core seat clamping assembly 200 includes a rotating base 210 and a valve core seat pressing assembly 500a. The rotating base 210 is used to place the valve core seat (not shown). It is driven by a rotating base motor 220 to rotate the three holes on the valve core seat to align with the nozzles of the three nylon tubes. The valve core seat pressing assembly 500a is used to press the rotated valve core seat to prevent it from rotating when assembled with the nylon tubes 620.

[0026] Each set of sliding plug-in components 300 includes a nylon tube moving platform 310 that moves toward the valve core seat clamping component 200, and the nylon tube moving platform 310 is provided with a nylon tube clamping component 320 and a valve body moving platform 330 that moves toward the nylon tube clamping component 320, wherein two valve body moving platforms 330 are provided with valve body clamping components 500b, and the upper surface of the valve body moving platform 330 is provided with a placement groove 331 for placing the valve body; the other valve body moving platform 330 is provided with a valve body clamping component 350, and the valve body clamped by the valve body clamping component 350 is trumpet-shaped; the valve body moving platform 330 is provided with a plug cylinder 341, and the end of the telescopic shaft of the plug cylinder 341 is fixed with a plug 340 for blocking the trumpet-shaped valve body, and the plug 340 is provided with an air tightness detection channel 342, and the air tightness detection channel 342 is connected to the air tightness detector.

[0027] Among them, the nylon tube clamping assembly 320 and the valve body clamping assembly 350 each include at least one lower pressure block 301, at least one upper pressure block 302 and a clamping drive cylinder 303. The lower pressure block 301 and the clamping drive cylinder 303 are both fixed on the machine 100. The upper pressure block 302 is located above the lower pressure block 301. The upper pressure block 302 is driven by the clamping drive cylinder 303 to move toward or away from the lower pressure block 301. When clamping the nylon tube 620, two upper pressure blocks 302 and two lower pressure blocks 301 can be provided according to the length and curvature of the nylon tube 620. The two upper pressure blocks 302 can be driven by one clamping drive cylinder 303, or the two upper pressure blocks 302 can be driven down (or dropped synchronously) by one clamping drive cylinder 303 respectively.

[0028] Depending on the installation environment, the clamping drive cylinder 303 can be partially arranged above the machine platform 100 and partially arranged below the machine platform 100 to better utilize the space.

[0029] like Figure 8As shown, the end surfaces of the upper pressing block 302 and the lower pressing block 301 of the nylon tube clamping assembly 320 are provided with a clamping groove 304 in the shape of the nylon tube 610. The end surfaces of the upper pressing block 302 and the lower pressing block 301 of the valve body clamping assembly 350 are provided with a clamping groove 304 in the shape of the valve body.

[0030] A nylon elastomer 306 is disposed in the clamping groove 304 of the nylon tube clamping assembly 320 , which enables the upper pressing block 302 and the lower pressing block 301 to better clamp the nylon tube 610 .

[0031] A vertical slide rail 305 is fixed on the machine platform 100, and the upper pressing block 302 is slidably arranged on the vertical slide rail 305 through a slider. The vertical slide rail 305 is used to provide a guide for the upper pressing block 302 to move up and down.

[0032] In addition, matching limit grooves 307 and protrusions 308 are provided on the corresponding end faces of the upper pressure block 302 and the lower pressure block 301. When the clamping drive cylinder 303 drives the upper pressure block 302 to move toward the lower pressure block 301, the protrusion 308 and the limit groove 307 are inserted into each other to play a guiding role.

[0033] A pair of horizontal supports 110 are fixed to the machine 100. The nylon tube moving platform 310 is slidably mounted on the horizontal supports 110 via matching sliders and rails. A nylon tube platform driving cylinder 120 is provided on the machine 100 to drive the nylon tube moving platform 310 toward the rotating base 210. Therefore, the nylon tube moving platform 310 moves horizontally to the valve core seat clamping assembly 200. An oblique insert pad 311 is fixed to the nylon tube moving platform 310. The valve body moving platform 330 is slidably mounted on the oblique insert pad 311 via matching rails and sliders. A valve body platform driving cylinder 312 is provided on the nylon tube moving platform 310 to drive the valve body moving platform 330 to move obliquely toward the nylon tube.

[0034] Therefore, the nylon tube moving platform 310 in this embodiment moves horizontally toward the valve core seat clamping assembly 200, while the valve body moving platform 330 moves along the inclined surface of the oblique insert pad 311 toward the nylon tube clamping assembly 320. The installation trajectories of the two are different, so that the installation of the nylon tube 610 and the valve core seat, and the installation of the valve seat 620 and the nylon tube 610 do not affect each other.

[0035] A matching limit assembly 400 is provided between the nylon tube moving platform 310 and the machine platform 100, and a matching limit assembly 400 is provided between the valve body moving platform 330 and the nylon tube moving platform 310. The limit assembly 400 between the nylon tube moving platform 310 and the machine platform 100 and the limit assembly 400 between the valve body moving platform 330 and the nylon tube moving platform 310 have the same structure, both including a limit block 410, a limit screw 420, and a hydraulic buffer 430. The limit block 410 can move back and forth between the limit screw 420 and the hydraulic buffer 430.

[0036] In the limiting assembly 400 between the nylon tube moving platform 310 and the machine 100 , the limiting block 410 is fixed on one side of the sliding nylon tube moving platform 310 , and the limiting screw 420 and the oil pressure buffer 430 are fixed on one side of the machine 100 .

[0037] In the limiting assembly 400 between the valve body moving platform 330 and the nylon tube moving platform 310, the limiting block 410 is fixed to one side of the sliding valve body moving platform 330, and the limiting screw 420 and the oil pressure buffer 430 are fixed to one side of the nylon tube moving platform 310.

[0038] In some embodiments, the limit screws 420 include a front limit screw and a rear limit screw fixed at the front and rear ends of the same side of the machine 100, distributed at the front and rear ends of the limit block 410, and one of the front limit screws and the rear limit screws 420 is arranged in parallel with the oil pressure buffer 430, which can better provide limitation.

[0039] The valve body pressing assembly 500b and the valve core seat pressing assembly 500a both include a pressing cylinder 510, a cylindrical connecting rod 520, a valve pressing rod 530, a connecting rod 540, a pressing shaft 550, and a pressing head 560. One end of the cylindrical connecting rod 520 is fixed to the telescopic shaft of the pressing cylinder 510, and the other end of the cylindrical connecting rod 520 is rotatably connected to one end of the valve pressing rod 530. One end of the connecting rod 540 is rotatably connected to the middle part of the valve pressing rod 530, and the other end is rotatably connected to the cylinder body of the pressing cylinder 510. The other end of the valve pressing rod 530 is vertically fixed to the pressing shaft 550, and the pressing head 560 is arranged at the end of the pressing shaft 550. The pressing head 560 of the valve body pressing assembly 500b is consistent in shape with the valve body 620, and the pressing head 560 of the valve core seat pressing assembly 500a is consistent in shape with the valve core seat.

[0040] Step 1: Clamp and fix three nylon tubes 610, two closed valve bodies 620 and one trumpet-shaped valve body 620:

[0041] The valve core seat is placed on the rotating base 210 and is driven to rotate by the rotating base motor 220 until the three mounting holes on the valve core seat correspond to the pipe openings of the three nylon tubes 610; the three nylon tubes 610 are placed on the lower pressing block 301 of the nylon tube clamping assembly 320, and the upper pressing block 302 of the nylon tube clamping assembly 320 is driven by the clamping drive cylinder 303 to move toward the direction close to the lower pressing block 301 (i.e. downward) to clamp the nylon tubes 610; the two closed valve bodies 620 are placed in the placement groove 331 on the valve body moving platform 330 and are pressed by the upper valve body clamping assembly 500b; the trumpet-shaped valve body 620 is placed on the lower pressing block 301 of the valve body clamping assembly 350, and then driven by the clamping drive cylinder 303 to move toward the direction close to the lower pressing block 301 (i.e. downward) to clamp the trumpet-shaped valve body 620.

[0042] Step 2: Move the clamped valve body 620 toward one end of the nylon tube 610 to achieve assembly engagement; move the other end of the nylon tube 610 toward the valve core seat to achieve assembly engagement:

[0043] The valve body moving platform 330 on the nylon tube moving platform 310 is driven by the valve body platform driving cylinder 312, and moves obliquely along the inclined upper surface of the oblique insertion pad 311 toward one end of the clamped nylon tube 610 until the assembly is engaged. The valve body platform driving cylinder 312 then drives the valve body moving platform 330 to reset; the nylon tube platform driving cylinder 120 drives the nylon tube moving platform 310 to move horizontally toward the valve core seat clamped on the rotating base 210 until the insertion and assembly are completed.

[0044] Step 3: Perform air tightness test on the assembled valve seat:

[0045] The valve body clamping assembly 350 that clamps the trumpet-shaped valve body 620 continues to clamp the trumpet-shaped valve body 620, and the valve body moving platform 330 corresponding to the trumpet-shaped valve body 620 does not reset. The plug cylinder 341 drives the plug 340 to move toward the trumpet-shaped valve body 620 until the valve body 620 is blocked. The air tightness test gas is introduced into the air tightness test channel 342 by the air tightness test instrument, and its air pressure is tested to detect the air tightness of the assembled valve seat.

[0046] Step 4: Cutting:

[0047] The nylon tube clamping assembly 320 and the valve body clamping assembly 350 loosen the nylon tube 610 and the valve body 620 respectively, and each cylinder is reset, and the robot can unload the material.
