All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 , Figure 2 and Figure 4The utility model provides a technical solution: a polyurethane cushion processing drilling positioning mechanism, comprising: a bottom plate 1 and a bracket 7, the bracket 7 is fixedly installed on the upper surface of the bottom plate 1, the bracket 7 is set to an inverted U shape, a driving mechanism 8 is arranged above the bracket 7, and the driving mechanism 8 is used to provide power for drilling, a first fixed plate 6 is fixedly installed in the middle of the bracket 7, two slide grooves 12 are provided on the lower surface of the first fixed plate 6, a slide rod 13 is fixedly installed in each slide groove 12, the slide groove 12 and the slide rod 13 are symmetrically arranged, a clamping mechanism 5 is arranged below the first fixed plate 6, the clamping mechanism 5 includes a clamping claw 20, a slide plate 22, a rotating block 23 and a third electric push rod 11, the two slide plates 22 are respectively extended into the two slide grooves 12 and are slidably connected thereto, the two slide rods 13 respectively penetrate the two slide plates 22 and are slidably connected thereto, the clamping claw 20 is fixedly installed on the lower surface of the slide plate 22, the clamping claw 20 is symmetrically arranged, and the symmetrical surfaces of the two clamping claws 20 are both set The concave inclined surface 21 is to ensure that the cylindrical buffer pad is clamped in the middle part of the clamping jaw 20 when the cylindrical buffer pad is clamped. The rotating block 23 is rotatably connected to the lower surface of the first fixed plate 6 through a cylindrical rotating shaft. The rotating block 23 is rotatably connected to the slide plates 22 on both sides through two connecting rods 24. One end of the connecting rod 24 extends into the rotating block 23 and is rotatably connected thereto. The other end of the connecting rod 24 is rotatably connected to one side of the slide plate 22. The middle part of the connecting rod 24 is bent. The third electric push rod 11 is fixedly mounted on the lower surface of the first fixed plate 6. The output end of the third electric push rod 11 is rotatably connected to a push-pull rod 25 through a connecting block. The end of the push-pull rod 25 away from the third electric push rod 11 extends into the rotating block 23 and is rotatably connected to the rotating block 23. The upper surface of the clamping jaw 20 is set as an inclined surface 21. The setting of the inclined surface 21 is to prevent waste after drilling from falling on the upper surface of the clamping jaw 20, thereby affecting the operation of the clamping jaw 20.

[0022] When in use, first place the object between the clamping jaws 20, and then start the third electric push rod 11. The third electric push rod 11 can indirectly drive the rotating block 23 to rotate, and the rotating block 23 will drive the connecting rods 24 on both sides to move together. The movement of the connecting rods 24 will drive the clamping jaws 20 to clamp. During the clamping process of the clamping jaws 20, a cylindrical buffer pad will move slightly between the clamping jaws 20 until it is clamped. After clamping, the clamped cylindrical buffer pad will be at the intersection of the inclined surface 21 between the two clamping jaws 20. At this time, start the driving mechanism 8 and drill a hole at its center point.

[0023] Embodiment 2

[0024] On the basis of the first embodiment, the driving mechanism 8 includes a second electric push rod 9 and a motor 14. The second electric push rod 9 is fixedly mounted on the upper surface of the bracket 7. The output end of the second electric push rod 9 passes through the top wall of the bracket 7 and is rotatably connected thereto. The output end of the second electric push rod 9 is fixedly connected to the lifting box 10. The motor 14 is fixedly mounted on the bottom of the lifting box 10. The output end of the motor 14 is fixedly connected to a rotating shaft. The output end of the motor 14 passes through the bottom wall of the lifting box 10 and the first fixed plate 6 through the rotating shaft. A drill bit is installed at the bottom of the rotating shaft. A through hole 27 is provided in the middle part of the rotating block 23. The output end of the motor 14 passes through the through hole 27 through the rotating shaft and is rotatably connected thereto. The output of the motor 14 passes through the middle part of the rotating block 23 to ensure that the drill bit is always in the middle part of the two clamps 20. In this way, no matter whether the size of the cylindrical buffer pad changes, as long as it is clamped by the clamp 20, its center position will correspond to the drill bit.

[0025] When the driving mechanism 8 is started, the motor 14 is started first, and the motor 14 will drive the drill bit to rotate. Since the output end of the motor 14 is in the middle position of the rotating block 23, the drill bit will be aligned with the middle position of the clamped cylinder. At this time, the second electric push rod 9 is started, and the second electric push rod 9 will drive the lifting box 10 to rise and fall, and the lifting box 10 will drive the motor 14 to rise and fall, thereby indirectly driving the drill bit to rise and fall, thereby completing the drilling action.

[0026] Embodiment 3

[0027] On the basis of the second embodiment, a positioning component 4 is arranged on the upper surface of the base plate 1. The positioning component 4 is to prevent the placed buffer pad from deviating too much from the center position, thereby causing jamming during the clamping process. The positioning component 4 includes a first electric push rod 2, a positioning plate 15 and a second fixed plate 16. The first electric push rod 2 and the two second fixed plates 16 are fixedly mounted on the upper surface of the base plate 1. The first electric push rod 2 makes it more convenient to discharge the material without placing the cylindrical buffer pad under the bracket 7. The output of the first electric push rod 2 is fixedly mounted with a push block 3. The push block 3 not only pushes the buffer pad to the clamping position, but After the drilling is completed, it is pushed away from the equipment. Two telescopic rods 17 are slidably connected to the second fixed plate 16. Springs 18 are slidably sleeved on the two telescopic rods 17. One end of the spring 18 is fixedly connected to the second fixed plate 16, and the other end of the spring 18 is fixedly connected to the alignment plate 15. The alignment plate 15 is used to adjust the position of the columnar buffer pad. When the position of the columnar buffer pad deviates too much, problems such as skewness may occur during the clamping process. One side of the push block 3 is set to an arcuate surface 19. The arcuate surface 19 is to prevent the buffer pad from being placed in an inaccurate position, and a certain correction can be obtained through the arcuate surface 19.

[0028] In actual use, the buffer pad is first placed above the bottom plate 1 and is in contact with the arc surface 19 for the best, or it can be fitted with the arc surface 19 during the pushing process of the first electric push rod 2. The first electric push rod 2 pushes the object between the clamping jaws 20, and then the third electric push rod 11 is started. The third electric push rod 11 can indirectly drive the rotating block 23 to rotate, and the rotating block 23 will drive the connecting rods 24 on both sides to move together. The movement of the connecting rods 24 will drive the clamping jaws 20 to clamp. During the clamping process of the clamping jaws 20, a cylindrical buffer pad will move slightly between the clamping jaws 20 until it is clamped. After clamping, the cylindrical buffer pad will be located on the inclined surface 21 between the two clamping jaws 20. At the intersection, the driving mechanism 8 is started at this time, and drilling can be performed at its center point. First, the motor 14 is started, and the motor 14 will drive the drill bit to rotate. Since the output end of the motor 14 is in the middle position of the rotating block 23, the drill bit will align with the middle position of the clamped cylinder. At this time, the second electric push rod 9 is started, and the second electric push rod 9 will drive the lifting box 10 to rise and fall, and the lifting box 10 will drive the motor 14 to rise and fall, thereby indirectly driving the drill bit to rise and fall, thereby completing the drilling action, turning off the motor 14, and causing the second electric push rod 9 to retract, starting the third electric push rod 11 to relax the clamping jaws 20, and finally starting the first electric push rod 2 to fully extend it and push the object away from the device.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
