Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1:
as shown in fig. 1 to 3, a pneumatic expander for three-finger cot assembly comprises a worktable 1 and a supporting plate 2 vertically arranged on the upper surface of the worktable 1, the supporting plate 2 is provided with a circular mounting table 3, six T-shaped sliding grooves 4 are uniformly arranged on the mounting table 3 along the circumferential direction, the small-size ends of the sliding grooves 4 are positioned on the surface of the mounting table 3 far away from the supporting plate 2, six sliding grooves 4 are connected with sliding blocks 5 matched with the sliding grooves in a sliding manner, one end of the sliding block 5, which is close to the circle center of the mounting table 3, is of a quadrangular frustum pyramid structure, a dovetail groove 6 is formed in one surface of the sliding block 5, which is close to the circle center of the mounting table 3, along the length direction of the sliding block 5, a connecting block 7 matched with the dovetail groove 6 is arranged in the dovetail groove 6, and an expansion rod 8 is fixedly connected to one surface of the connecting block 7, which is far away from the supporting plate 2;
the one end that the centre of a circle of mount table 3 was kept away from to slider 5 is connected with the piston rod of cylinder 9, cylinder 9 passes through mounting panel 10 to be fixed on the backup pad 2.
Because the whole expander does not have displacement along the direction vertical to the supporting plate 2 in the whole working process, the connecting block 7 cannot slide out of the dovetail groove 6.
The working principle is as follows: the support tubes required for the three finger cuffs of different sizes (the shapes of which correspond to those of the three finger cuffs) are first replaced by replacing the connecting blocks 7 so as to replace the corresponding expansion rods 8. The expansion rods 8 are in an initial state, and the six expansion rods 8 are folded close to the center of the mounting table 3 in the initial state; then, the six expansion rods 8 are fitted with cold shrinkable cable accessories (the cold shrinkable cable accessories referred to herein are elastomeric materials (commonly used silicone rubber and ethylene propylene rubber) injection-vulcanized in a factory). Starting the air cylinders 9 and controlling the six air cylinders 9 to act synchronously (the air cylinders 9 can be controlled by parallel air pipes with the same length and then controlled by an electromagnetic valve, which is the prior art and is not described herein any more), the air cylinders 9 drive the sliding blocks 5 to move along the sliding grooves 4 in the direction away from the center of the mounting table 3 until the cold-shrinkable cable accessory is expanded to a proper size. At the moment, one finger of the supporting tube extends into the expanded cold-shrinkable cable accessory, then the cylinder 9 is started, the cylinder 9 drives the sliding block 5 to gather along the sliding groove 4 towards the direction close to the center of the mounting table 3, and when the expansion rod 8 is contacted with the supporting tube, the cold-shrinkable cable accessory and the supporting tube are manually taken down at the same time, so that the cold-shrinkable cable accessory is supported on the supporting tube. And then repeating the operation to wrap the cold-shrinkable cable accessory on the support tube to finish the assembly.
The T-shaped sliding groove 4 can prevent the sliding block 5 from falling out, and can guide the sliding block 5, so that the use is convenient.
The expanding machine of the utility model can replace the expanding rods 8 with different sizes, thereby meeting different use requirements; the T-shaped sliding groove 4 can prevent the sliding block 5 from falling out, and can guide the sliding block 5, so that the use is convenient.
Further, the mounting panel 10 be "L" font, the mounting panel 10 with the perpendicular fixed connection of backup pad 2, set up the first through-hole that is used for the cylinder 9 piston rod to pass on the mounting panel 10, the cylinder 9 with pass through bolted connection between the mounting panel 10. The L-shaped mounting plate 10 is convenient for fixing the air cylinder 9 on the supporting plate 2, and simultaneously, the piston rod of the air cylinder 9 is ensured to be parallel to the supporting plate 2.
Further, the mounting panel 10 on be equipped with the second through-hole, sliding connection has guide bar 11 in the second through-hole, guide bar 11 keeps away from the one end of mounting panel 10 through the deflector that is "L" font with slider 5 fixed connection, guide bar 11 with the piston rod parallel arrangement of cylinder 9. The guide rod 11 can avoid the deviation of the track when the sliding block 5 moves, and the expansion effect is ensured.
Example 2:
as shown in fig. 4 and 5, in this embodiment, on the basis of embodiment 1, a positioning rod 12 is disposed on the supporting plate 2, the positioning rod 12 is disposed coaxially with the mounting table 3, a first positioning ring 13 and a second positioning ring are sequentially slidably disposed at one end of the positioning rod 12 away from the supporting plate 2, the first positioning ring 13 and the second positioning ring both include an inner ring 14 and an outer ring 15 connected to the inner ring 14, and the inner ring 14 is matched with the positioning rod 12.
For convenience of description, three tubes with smaller diameter of the supporting tube are fingers, and a straight tube with larger diameter of the supporting tube is an arm. The outer diameter of the first retaining ring 13 matches the inner diameter of the "finger" of the support tube, and the outer ring 15 of the second retaining ring matches the inner diameter of the "arm" of the support tube. When assembling the 'finger', firstly sleeving the 'finger' into the first positioning ring 13, then sleeving the 'finger' into the outside of the first positioning ring 13, then sliding the supporting tube into the cold-shrinkable cable accessory, and synchronously sliding the first positioning ring 13; similarly, when assembling the "arm", the second positioning ring is first inserted, and then the process is the same as described above. Through setting up locating lever 12 and holding ring, guaranteed that the stay tube assembly is coaxial with mount table 3 all the time, guaranteed that the even shrink of cold contraction type cable accessories ability has guaranteed the assembly effect on the stay tube.
Furthermore, a limiting block 16 is arranged at the end part of the positioning rod 12 far away from the supporting plate 2, and a limiting hole 17 matched with the limiting block 16 is formed in the inner ring 14. When the first positioning ring 13 is sleeved, the limiting block 16 is aligned with the limiting block 16 to be sleeved into the positioning rod 12, and after the positioning rod 12 is sleeved, the first positioning ring 13 is rotated by a certain angle to make the limiting hole 17 and the limiting block 16 dislocate. This ensures that the first positioning ring 13 cannot be disengaged from the stop 16 when the support tube is removed. The second positioning ring is sleeved in the first positioning ring. When the second supporting pipe is assembled, the second positioning ring can be continuously used only by being taken down.
The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
