[0025] In the embodiment, the triangular clamping device 7 is clamped or loosened the part 9 arranged between the triangular clamping device 7 by the extension of the drive cylinder 8, so as to clamp the part 9 to be processed for processing.
[0026] Preferably, the clamping column 6 and the supporting column 5 of the embodiment are provided with connecting pieces 10 at the bottom, and are bolted with the rotary block 4 through the connecting pieces 10.
[0027] The rest is the same as in example 1.
[0028] In the embodiment, the triangular clamping device 7 is clamped or loosened the part 9 arranged between the triangular clamping device 7 by the extension of the drive cylinder 8, so as to clamp the part 9 to be processed for processing.
[0029] In the embodiment, the triangular clamping device 7 is clamped or loosened the part 9 arranged between the triangular clamping device 7 by the extension of the drive cylinder 8, so as to clamp the part 9 to be processed for processing. Figures 2-4 As shown in FIG. 3, the sleeve column 71 is fixedly arranged at the center of the clamping column 6, the sleeve ring 72 is rotatably sleeved on the sleeve column 71, and the three clamping units are uniformly arranged on the side surface of the sleeve ring 72 along the circumference.
[0030] Each clamping unit comprises a sliding fixing piece 73, a sliding moving piece 74, a rotating piece 75 and a rotating rod 76.
[0031] The triangular clamping device 7 in the embodiment is mainly used for clamping the cylindrical part 9. Figure 2As shown, the driving cylinder drives the corresponding sliding moving part 74 to slide towards the part 9. The movement of the sliding moving part 74 drives the end of the screwing rod 76 connected to the sliding moving part 74 to move towards the part 9. The force on the end of the screwing rod 76 connected to the screwing part 75 drives the screwing part 75 on the collar 72 to move clockwise, which drives the collar 72 to rotate clockwise. The rotation of the collar 72 drives the other two screwing parts 75 to rotate clockwise, which in turn drives the sliding moving parts 74 connected to the screwing parts 75 to move towards the part 9. The three sliding moving parts 74 move towards the part 9, and the continuous extension of the driving cylinder 8 drives the three sliding moving parts 74 to continuously press and fix the part 9.
[0032] When the part 9 needs to be released, the driving cylinder 8 is retracted away from the part 9, which drives the sliding moving part 74 to move away from the part 9. The end of the screwing rod 76 connected to the sliding moving part 74 moves away from the part 9, which in turn drives the other end of the screwing rod 76 to rotate counterclockwise, driving the collar 72 to rotate counterclockwise. The counterclockwise rotation of the collar 72 drives the end of the screwing rod 76 connected to the screwing part 75 to rotate counterclockwise, which in turn drives the end of the screwing rod 76 connected to the other two sliding moving parts 74 to move away from the part 9. The other two sliding moving parts 74 are forced to slide away from the part 9, and the three sliding moving parts 74 no longer press the part 9.
[0033] Preferably, the height of the sleeve column 71 is higher than the height of the collar 72. The top of the sleeve column 71 is provided with a limiting disc 11, the outer diameter of the limiting disc 11 is larger than the outer diameter of the sleeve column 71, and the limiting disc 11 extends to the upper surface of the collar 72. The limiting disc 11 can limit the collar 72, ensuring that the collar 72 can always rotate on the sleeve column 71 without sliding out of the sleeve column 71, and can also be more convenient for placing the part 9.
[0034] The rest is the same as in Example 2.
[0035] In this embodiment, the sliding moving part 74 includes a sliding part 741 and a clamping part 742. The sliding part 741 is connected to the sliding fixing part 73, and the clamping part 742 is higher than the collar 72 and the sleeve column 71 and is integrally formed with the sliding part 741, i.e. the clamping part 742 is also higher than the limiting disc 11. The end of the sliding part of one of the sliding moving parts 74 is connected to the driving cylinder 9.
[0036] The rest is the same as in Example 3.
[0037] In this embodiment, the part of the sliding moving part 74 where the screwing rod 76 is connected is the part of the sliding part 741 close to the collar 72. The part of the sliding part 741 close to the collar 72 is provided with a screwing groove 77, and a connecting rod 78 is vertically arranged in the screwing groove 77. The end of the screwing rod 76 is rotatably sleeved on the connecting rod 78.
[0038] The rest is the same as example 4.
[0039] The structure of the sliding part 741 and the clamping part 742 is set to better set the screw groove 77 and the connecting rod 78, and facilitate the screw connection of the sliding moving part 74 and the screw part 76.
[0040] In the embodiment 6, the sliding part 741 and the sliding fixing part 73 are connected in the sliding mode as shown in the figure. Figure 5 As shown in the figure, the two sides of the sliding fixing part 73 are inwardly provided with a sliding groove 12, the width of the sliding part 741 is wider than the width of the sliding fixing part 73, and the two sides of the sliding part 741 are downwardly provided with a sliding part 13 with an L-shaped cross section, and the horizontal part of the sliding part 13 is slidably clamped in the sliding groove 12.
[0041] The rest is the same as example 5.
[0042] The sliding part 741 and the sliding fixing part 73 of the embodiment are connected in the sliding mode, which ensures the sliding and also makes the connection more stable.
[0043] The above-described embodiments are only preferred embodiments of the utility model for description, and do not limit the design concept and scope of the utility model, and various modifications and improvements of the technical scheme of the utility model made by ordinary engineering technicians in the art without departing from the design concept of the utility model shall fall within the protection scope of the utility model, and the technical content of the utility model claimed for protection has been recorded in the technical requirements.
