[0021] Combined with Figures 1 to 5 As shown, this embodiment discloses an automatic grabbing and pressing device for electrode caps of electric fusion pipe fittings, an automatic grabbing and pressing device for electrode caps of electric fusion pipe fittings, comprising a right-angle three-coordinate manipulator 1, a slide cylinder 5 and a grabbing and pressing mechanism, wherein the right-angle three-coordinate manipulator 1 is connected and fixed to a manipulator fixing frame 4 by 8 hexagon socket screws. A slide cylinder 5 is provided on the right-angle three-coordinate manipulator 1, and the slide cylinder 5 is connected to the grabbing and pressing mechanism. The right-angle three-coordinate manipulator 1 can move up and down, front and back, and left and right, thereby improving the flexibility of grabbing and pressing the electrode cap 11.

[0022] The slide cylinder 5 is fixed on the sliding block of the rectangular three-coordinate manipulator 1 through the slide cylinder fixing plate 2. The slide cylinder fixing plate 2 and the sliding block of the rectangular three-coordinate manipulator 1 are connected and fixed by four hexagon socket screws. The slide cylinder 5 and the slide cylinder fixing plate 2 are connected and fixed by four hexagon socket screws.

[0023] The grabbing and pressing mechanism includes a pair of finger cylinders 7, a finger cylinder fixing frame 6, a grabbing and pressing head mounting frame 8 and four grabbing and pressing heads 9. The slide cylinder 5 is connected to the finger cylinder fixing frame 6. A pair of finger cylinders 7 are arranged below the finger cylinder fixing frame 6. A pair of grabbing and pressing heads 9 are arranged below the finger cylinder 7. A grabbing and pressing head mounting frame 8 is arranged below the finger cylinder 7. The grabbing and pressing head 9 is fixed on the grabbing and pressing head mounting frame 8. The finger cylinder fixing frame 6 is connected and fixed to the slide of the slide cylinder 5 by 4 hexagon socket screws, and the grabbing and pressing head mounting frame 8 is connected and fixed to the fingers of the finger cylinder 7 by 2 hexagon socket screws.

[0024] The grabbing and pressing head 9 is connected and fixed to the grabbing and pressing head mounting frame 8 by two hexagon socket screws. Two waist-shaped holes 10 are formed on the grabbing and pressing head 9. The hexagon socket screws pass through the waist-shaped holes 10 and are connected to the grabbing and pressing head mounting frame 8. The electrode cap grabbing and pressing head 9 can adjust the front and rear position on the grabbing and pressing head mounting frame 8 through the waist-shaped holes 10 on the upper side to control the force of grabbing the electrode cap 11, so as to avoid deformation of the electrode cap due to excessive grabbing force or failure to firmly grasp the electrode cap 11 due to insufficient grabbing force, thereby improving the stability of grabbing and pressing the electrode cap.

[0025] The specific implementation process of the device of the utility model in the production process is as follows: first, the entire device is fixed on the electric fusion pipe assembly and packaging line through the manipulator fixing frame 4, and then the waist-shaped hole 10 on the upper side of the electrode cap grabbing and pressing head is used to adjust its front and rear position on the grabbing and pressing head mounting frame 8 to control the force of grabbing the electrode cap 11, so that the electrode cap 11 is grabbed without deformation but will not fall off. After that, the device is started. After the front-end vibration disk conveying mechanism conveys the electrode cap into place, the right-angle three-coordinate manipulator 1 moves and drives the slide cylinder fixing plate 2 and the upper grabbing and pressing mechanism to move to just above the position where the electrode cap is in place. Then the slide cylinder 5 moves downward to drive the grabbing and pressing cylinder fixing frame 5 and the mechanism connected on the upper side to move downward. After moving down to place, the two finger cylinders 7 simultaneously perform a clamping action to drive the grabbing and pressing head 9 to grab the electrode cap 11. Then the slide cylinder 6 moves up and returns to its original position. The right-angle three-coordinate manipulator 1 drives the slide cylinder fixing plate 2 and the upper mechanism to move to just above the electric fusion pipe fitting. Then the slide cylinder 6 moves downward to drive the grabbing and pressing cylinder fixing frame 5 and the upper mechanism to move downward. After moving down to place, the left and right electrode caps 11 are respectively inserted into the electrode columns 12 on the left and right sides of the electric fusion pipe fitting 3. Then the finger cylinder 13 performs a loosening action to drive the grabbing and pressing head 9 to release the electrode cap 11, thereby completing the installation of the electrode cap 11. After that, the device waits for the next electric fusion pipe and the next set of electrode caps to arrive in preparation for the next grabbing and pressing.

[0026] The utility model can automatically grab and press the electrode cap onto the electrode column of the electric fusion pipe fitting, thereby improving the efficiency of pressing the electrode cap and reducing the labor intensity of workers. The force of pressing the electrode cap is uniform, eliminating the situation where the electrode cap is not pressed into place, and is beneficial to improving the quality of the finished product.

[0027] The above description is only a preferred implementation mode of the utility model, and does not impose any form of limitation on the utility model. Any simple modification, equivalent change or modification made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
