DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] A feeding mechanism for a special-shaped water pipe comprises: a first driving member 6; a second driving member 7, which is connected to the output end of the first driving member 6; a fixing member 8, which has an expanded state and a closed state, the expanded state is used to receive the special-shaped water pipe 24, or to take the special-shaped water pipe 24 out of the fixing member 8, and the closed state is used to fix the special-shaped water pipe 24, and the fixing member 8 and the output end of the second driving member 7 are movably abutted; a guide block 9, which is connected to the second driving member 7 and is sleeved on the outside of the fixing member 8, the guide block 9 is used to limit the relative rotation between the fixing member 8 and the guide block 9, and allow the fixing member 8 to move between a maximum movement position away from the second driving member 7 and a pressing position abutting against the output end of the second driving member 7; the fixing member 8 can be in an expanded state due to being in the maximum movement position, and can move from the maximum movement position to the pressing position due to being in the closed state.

[0035] Based on the above embodiments, an exemplary structure of this solution is as follows: Figures 1 to 7 As shown, the feeding mechanism 3 of the present scheme is a part of a press-fitting device for special-shaped water pipes, and the press-fitting device also includes a support frame 1; a workbench 2, which is arranged on the support frame 1, and the feeding mechanism 3 is arranged on the workbench 2; a fixing component 4, which is arranged on the workbench 2 and is located on the side of the feeding mechanism 3, and the fixing component 4 is used to fix the workpiece 25 to be press-fitted with the special-shaped water pipe 24; a detection component 5, which has a visual sensor 19 arranged on the support frame 1, and the visual sensor 19 is electrically connected to the first driving member 6, and is used to sense whether there is a special-shaped water pipe 24 on the fixing member 8.

[0036] In the initial state, the workpiece 25 is fixed by the fixing assembly 4, and the first driving member 6 drives the second driving member 7 to move along the upper edge of the workbench 2. Figure 2 As shown, the fixing member 8 moves from the right to the left, thereby providing space for the fixing member 8 to move from the abutting position on the guide block 9 to the maximum movement position. During operation, the second driving member 7 or manual operation can move the fixing member 8 from the abutting position to the maximum movement position. At this time, the fixing member 8 is no longer constrained by the guide block 9 and can be unfolded. After the fixing member 8 is unfolded, the special-shaped water pipe 24 to be assembled is placed therein, and the fixing member 8 is switched from the unfolded state to the closed state, and then the fixing member 8 is pushed into the guide block 9 together with the special-shaped water pipe 24. Then, the first driving member 6 resets by driving the second driving member 7, and finally the second driving member 7 pushes the fixing member 8 to move the special-shaped water pipe 24 toward the workpiece 25, thereby completing the assembly of the special-shaped water pipe 24 and the workpiece 25.

[0037] In this solution, a fixing member 8 having two states, open and closed, is provided to fix the special-shaped water pipe 24 to be assembled. At the same time, the rotation of the fixing member 8 is limited by the guide block 9, and it is only allowed to move linearly between the abutting position and the maximum movement position, ensuring the installation position and angle of the special-shaped water pipe 24 are accurate. The first driving member 6 drives the second driving member 7 to move, providing necessary space for the fixing member 8 to move between the two positions, and finally realizing the precise press-fitting of the special-shaped water pipe 24 on the workpiece 25.

[0038] In this solution, the first driving member 6 and the second driving member 7 can be cylinders or motors. The visual sensor 19 is electrically connected to the first driving member 6 to prevent the first driving member 6 from starting in the event of an accidental touch when there is no special-shaped water pipe 24 on the fixing member 8.

[0039] Furthermore, a rectangular groove 10 is provided on the guide block 9, and the cross section of the fixing member 8 matches the rectangular groove 10. Such a design realizes the anti-rotation function of the guide block 9 on the fixing member 8, and allows the fixing member 8 to move linearly between the pressing position and the maximum movement position.

[0040] The fixing member 8 includes: a first fixing plate 11, one end of which is provided with a rotating shaft 13; a second fixing plate 12, one end of which is rotatably sleeved on the rotating shaft 13 and movably abuts against the first fixing plate 11, and a fixing groove 14 is provided on the opposite side of the first fixing plate 11 and the second fixing plate 12. When the first fixing plate 11 and the second fixing plate 12 are in contact, the two fixing grooves 14 enclose and form a fixed space that is adapted to the shape of the special-shaped water pipe 24.

[0041] During operation, the first fixing plate 11 and / or the second fixing plate 12 rotates along the axis direction of the rotating shaft 13, so that the first fixing plate 11 and the second fixing plate 12 are brought close to or separated from each other, so as to realize the switching of the fixing member 8 between the expanded state and the closed state.

[0042] A limiting column 15 is provided on the first fixed plate 11, and a limiting portion 16 with a diameter larger than that of the limiting column 15 is provided on the limiting column 15; a through slot 17 for the limiting column 15 and the limiting portion 16 to pass through is provided on the second fixed plate 12, and a limiting baffle 18 is movably inserted on the limiting column 15, and the limiting baffle 18 is used to limit the limiting column 15 and the limiting portion 16 from passing through the through slot 17.

[0043] like Figure 3 As shown, at this time, the stopper 18 is inserted into the stopper column 15 and is located between the stopper portion 16 and the second fixing plate 12. The stopper 18 prevents the stopper column 15 from moving away from the second fixing plate 12, so that the fixing member 8 remains in the closed state. When the stopper 18 is pulled out from the stopper column 15, the restriction of the stopper column 15 is released, and under the action of external force, the first fixing plate 11 and the second fixing plate 12 are separated, so that the fixing member 8 can be converted to the unfolded state.

[0044] Furthermore, the detection component 5 includes: a third driving member 20, which is vertically arranged on the support frame 1, and the output end of the third driving member 20 is arranged toward the workbench 2; a connecting frame 21, which is connected to the output end of the third driving member 20, and the visual sensor 19 is connected to the connecting frame 21.

[0045] The third driving member 20 may be a cylinder or a motor. The connecting frame 21 is used to connect the third driving member 20 and the connecting frame 21. The third driving member 20 drives the connecting frame 21 to move, thereby realizing the movement of the visual sensor 19 in the vertical direction.

[0046] The fixing assembly 4 includes a fourth driving member 22, a fixing block, and a clamping block 23 arranged on the workbench 2. The fixing block is connected to the fourth driving member 22. The middle position of the clamping block 23 is rotatably connected to the fixing block. One end of the clamping block 23 is connected to the output end of the fourth driving member 22 and movably abuts against the end face of the workpiece 25 for fixing the workpiece 25.

[0047] The fourth driving member 22 can be a cylinder, a motor or an oil cylinder. When working, the fourth driving member 22 drives one end of the clamping block 23 to rise or fall in the vertical direction, and drives the other end of the clamping block 23 to move closer to or away from the workpiece 25, thereby achieving compression or relaxation of the workpiece 25.

[0048] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
