[0020] Each inner clamping rod 61 is composed of three rectangular rods, and two of the rectangular rods are respectively fixedly connected to both sides of the other rectangular rod and are arranged in a staggered manner front and back. The inner wall of the grooved pipe fittings is clamped through the rotary cylinders 62 installed on the two relatively far rectangular rods. The outer walls of the two relatively close rectangular rods are movably sleeved with limit sleeves 68; A chute is opened at the top of the processing table 1, and the bottom of the movable support plate 5 is slidably connected in the chute.

[0023] Working principle: When grinding groove pipe fittings, one side of the joint of the groove pipe fitting needs to be placed on the U-shaped support frame 16, and then the three electric push rods one 11 on the left side are started to move towards the center of the circle, so as to push the roller 12 close to the outer wall of the groove pipe fitting to achieve preliminary fixation; Then, according to the diameter of the groove pipe fitting, by starting the electric push rod three 15, after adjusting the groove pipe fitting to be horizontal, at this time, the annular groove at the top of the groove pipe fitting will abut against the grinding block 89, and through the reset spring 86, an adaptive contact is generated, so that the grinding block 89 can always fit against the annular groove of the groove pipe fitting; Then, by starting the electric push rod two 13, at this time, the movable support plate 5 is pulled, and when the outer wall of the rectangular push plate 65 contacts the groove pipe fitting, it has the effect of axially fixing the groove pipe fitting, and through continuous extrusion, the distance between the rectangular push plate 65 and the movable support plate 5 will be shortened at this time, so as to compress the spring two 67, and through the L-shaped push rod 66, the limiting sleeve 68 is pushed to move until the limiting sleeve 68 disengages from the contact with the two inner clamping rods 61, and under the push of the spring one 64, the two inner clamping rods 61 are pushed to move away from each other, so as to synchronously drive the two rotating cylinders 62 to move away, and the two rotating cylinders 62 are directly clamped to the inner wall of the groove pipe fitting to realize the clamping of the inner wall of the groove pipe fitting, so that when grinding the annular groove of the groove pipe fitting, it can be more stable to improve the grinding effect; When the grinding is completed, by rotating the bidirectional screw 694, under the limitation of the limiting rod 693, the two movable plates 692 are made to approach each other, and the two inner clamping rods 61 are pushed to approach each other, so as to achieve the purpose of resetting.

[0025] The outer clamping mechanism 7 further includes: The second expansion rods 76 are connected to the other side of the outer clamping rods 71; Two first racks 77 are respectively movably connected within the movable support plate 5, and the first racks 77 are connected to the other side of the second telescopic rod 76; The first elastic telescopic rods 78 are fixedly connected inside the movable support plate 5 and push the two first elastic telescopic rods 78 away from each other; Two second racks 791 are respectively fixedly connected to the bottoms of the two inner clamping rods 61; Two gears 79 are respectively rotatably connected inside the movable support plate 5 and are respectively meshed with the first rack 77 and the second rack 791.

[0026] Working principle: First, under the action of the first telescopic rod 75, the outer clamping rod 71 is pulled to move, thereby driving the connecting rod 72 and the arc-shaped clamping plate 73 to approach the grooved pipe fitting, and directly positioning into the annular groove of the grooved pipe fitting through the ball 74 to achieve external fixation. When the movable support plate 5 moves, the second telescopic rod 76 contracts to keep the ball 74 always moving within the annular groove. And when the two inner clamping rods 61 move away from each other, the two second racks 791 will be driven to move outwards. Through the transmission of the gear 79, the two first racks 77 will be driven to move inwards, thereby pulling the second telescopic rod 76 to contract, and further contracting through the outer clamping rod 71, cooperating with the connecting rod 72 and the arc-shaped clamping plate 73 to improve the external clamping effect on the grooved pipe fitting.

[0027] Please refer to Figures 1-8 , on the basis of the above-mentioned embodiment, in another embodiment of the present invention, the cleaning mechanism 8 includes: The second elastic telescopic rods 81 are installed in the installation grooves formed at the top of the rectangular push plate 65; The movable blocks 82 are fixedly connected to the tops of the second elastic telescopic rods 81; The adjusting plates 83 are arranged on one side of the movable blocks 82, and the bottoms of the adjusting plates 83 are provided with brush hairs 84.

[0028] The cleaning mechanism 8 further includes: The bottom of the movable block 82 is provided with a groove. A rotating shaft 88 is rotatably connected to the left side of the movable block 82.

[0029] Working principle: When the grooved pipe fittings come into contact with the grinding head 89, the elastic telescopic rod two 81 at the bottom of the movable block 82 generates vertical movement, so as to adapt to the grinding of grooved pipe fittings with different diameters. First, by starting the first motor 4, the rotating plate 9 is driven to rotate, which in turn drives the overall rotation of the grooved pipe fittings. A grinding belt is provided on the left side of the rectangular push plate 65, so that the side of the grooved pipe fittings can be ground. Then, by starting the second motor 87, when the second motor 87 rotates, the rotating shaft 88 is driven to rotate, which in turn drives the grinding head 89 to rotate, so that the annular groove on the outer wall of the grooved pipe fittings can be ground. At the same time, by the rotation of the rotating shaft 88, the oval turntable 891 is driven to rotate. Furthermore, the contact plate 85 is pushed upward by the side of the oval turntable 891 far from the center of the circle. When the side of the oval turntable 891 close to the center of the circle contacts the contact plate 85, under the action of the return spring 86, the contact plate 85 is pushed downward. By the continuous up and down movement of the contact plate 85, the bristles 84 on the adjusting plate 83 are continuously pushed up and down through the U-shaped frame 892 to continuously contact the grinding block 89, so that the grinding block 89 can be cleaned to maintain the grinding accuracy of the grinding block 89 at the groove and improve the grinding effect.
