Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
Referring to the attached drawings 1 to 4 of the specification, the present invention relates to a follow-up pressing mechanism, which comprises a support frame 1 and a guide rail fixing plate 4. The support frame 1 is provided with a fixing ring 2 for height adjustment; and the fixing ring 2 is provided with an angle adjusting plate 3 for adjusting the angle. The angle adjusting plate 3 is provided with a waist-shaped adjusting through hole 5; the bottom surface of the guide rail fixing plate 4 is provided with a first screw 6 and a second screw 7, the first screw 6 is fixedly connected with the angle adjusting plate 3, and the second screw 7 penetrates through the waist-shaped adjusting through hole 5 and is clamped with the waist-shaped adjusting through hole. The top surface of the guide rail fixing plate 4 is provided with a guide rail 8, and a sliding block 9 is arranged on the guide rail 8 in a rolling manner; the top surface of the guide rail fixing plate 4 is also provided with an air cylinder bracket 17, and the sliding block 9 penetrates through the air cylinder bracket 17 and is in sliding connection with the air cylinder bracket 17. One end of the sliding block 9 is fixedly provided with a limiting block 13 for limiting the moving distance of the sliding block 9; the other end of the sliding block 9 is fixedly provided with a guide block 14; the top surface of the guide block 14 is slidably provided with a wedge-shaped driving block 15 and a wedge-shaped follow-up block 16, and the wedge-shaped driving block 15 is obliquely matched with the wedge-shaped follow-up block 16; the air cylinder support 17 is provided with an air cylinder 10, the air cylinder 10 is provided with a piston rod 19 matched with the air cylinder 10, and the piston rod 19 penetrates through the air cylinder support 17 and is in sliding connection with the air cylinder support; the wedge-shaped driving block 15 is connected with the piston rod 19; the top end of the wedge type follow-up block 16 is provided with a cam follower 11.
Preferably, but not limited to, the bottom of the supporting frame 1 is provided with a supporting base 12, and the supporting base 12 is provided with a mounting hole, so that the mechanism can be stably mounted at a desired position.
Preferably, but not limited to, a spring 18 is provided between the wedge follower block 16 and the guide block 14 to increase the force action.
Preferably, but not limited to, the width of the limiting block 13 is not less than the width of the cylinder bracket 17, so that the cylinder bracket 17 can clamp the limiting block 13, and the movement of the sliding block 9 is limited.
The utility model discloses a use method does:
mounting the support base 12 in position adjacent the weld station 20; the vertical height of the angle adjusting plate 3 is adjusted to a proper position by using the fixing ring 2; and when the second screw 7 is loosened, the guide rail fixing plate 4 rotates around the first screw 6, the angle of the guide rail fixing plate 4 can be adjusted, the cam follower 11 is matched with the welding table 20, and the angle can be fixed by locking the second screw 7 after the required angle is adjusted.
