Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the embodiments of the present invention are not limited thereto.
Among the prior art, rise the production that the axle satisfied different specification products through the preparation new dimension, have certain drawback, consequently, the utility model provides an axle that rises is with increasing footpath piece device for the cooperation is installed on axle 1 that rises, realizes matcing the production needs of different tube core specifications, is convenient for produce the tubular product of various different specifications.
As shown in fig. 1, the diameter increasing block device 2 and the expansion shaft 1 are two independent structures, the diameter increasing block device 2 is detachably mounted on the outer wall of the expansion shaft 1, the diameter increasing block device 2 is provided with an acting surface 3 coaxially arranged with the expansion shaft 1, and the distance between the acting surface 3 and the outer wall of the expansion shaft 1 is adjustable. Because the acting surface 3 is in contact with the tube core instead of the outer wall of the expanding shaft 1, the length of the diameter increasing block device 2 is less than or equal to the length of the expanding shaft 1 along the axial direction.
After the diameter increasing block device 2 is installed on the expanding shaft 1, the expanding shaft 1 is contacted with a tube core through the acting surface 3, different diameters are given to the expanding shaft 1 by adjusting the distance between the acting surface 3 and the outer wall of the expanding shaft 1, so that the size of the shaft diameter of the whole expanding shaft 1 device is adjusted, and one shaft diameter corresponds to the tube core.
Combine fig. 1 and fig. 2, for realizing adjusting the distance between action face 3 and the outer wall that rises axle 1, increase a footpath piece device 2 and include that the polylith increases a footpath nylon piece 4, polylith increases a footpath nylon piece 4 and evenly winds the establishment with the center pin that rises axle 1. Meanwhile, the diameter-increasing nylon block 4 is provided with various sizes and specifications, a first arc surface 41 and a second arc surface 42 which are arranged in parallel are formed on two opposite sides of the diameter-increasing nylon block 4 respectively, the first arc surface 41 is attached to the expanding shaft 1, and an acting surface 3 is formed between the second arc surfaces 42. When the diameter-increasing nylon blocks 4 of different specifications are adopted, the distance between the action surface 3 and the outer wall of the expansion shaft 1 is naturally adjusted, and the shaft diameter of the whole expansion shaft 1 is also naturally adjusted.
Increase a footpath nylon piece 4 for the staff uses different specifications, increase a footpath nylon piece 4 and rise and be equipped with mounting structure in order to realize dismantling the connection between the axle 1. Therefore, only the diameter increasing block devices 2 with different specifications need to be replaced on the same expanding shaft 1, and the trouble that the time spent on replacing the expanding shaft 1 devices with different specifications is long and frequent is reduced, so that the production efficiency is improved.
In detail, mounting structure includes a plurality of fastening screws 5, and two are no less than to quantity, increases and sets up a plurality of guiding holes 6 of wearing to establish first arc surface 41, second arc surface 42 simultaneously on the nylon block 4, and the size of guiding hole 6 sets to just making fastening screws 5 pass through, and the quantity of guiding hole 6 corresponds with fastening screws 5. A plurality of locking screw holes 7 have been seted up on the axle 1 that rises, and the quantity of locking screw hole 7 equals with the sum of all fastening screw 5, when fastening screw 5 and locking screw hole 7 threaded connection, increases the nylon block 4 and fixes on the axle 1 that rises under the same cooperation that increases all fastening screw 5 in the nylon block 4 of footpath.
Increase the in-process of footpath nylon piece 4 with the change in the installation, only need through work piece such as automatic screw locking instrument alright screw up or loosen fastening screw 5 to the realization will increase footpath nylon piece 4 and fix on rising axle 1, perhaps pull down and increase footpath nylon piece 4, reasonable in design, it is very convenient.
In order to ensure the structural strength of the diameter-increasing nylon blocks 4, a gap is formed between every two adjacent diameter-increasing nylon blocks 4, the size of the gap cannot be set too small, the gap is arranged, the diameter-increasing nylon blocks 4 cannot be mutually extruded to apply acting force when stressed, and the possibility of deformation caused by stress concentration is reduced; in addition, the gap is formed, so that direct contact between the diameter increasing nylon blocks 4 is avoided, material cost is saved, the contact area between the tube core card and the diameter increasing nylon blocks 4 is reduced when the diameter increasing block device 2 is matched with the tube core, friction is reduced, the tube core is conveniently sleeved on the diameter increasing block device 2, and the tube core is also convenient to take down.
As shown in fig. 2, after the diameter-increasing nylon block 4 is fixed, the elastic buffer block 8 is arranged in the gap, a sponge can be adopted, when the diameter-increasing nylon block 4 is stressed, the elastic buffer block 8 can absorb partial acting force from the two diameter-increasing nylon blocks 4 which are in contact with the elastic buffer block, and the tube core cannot be abraded by the sponge.
Because the setting in clearance, increase the edge of footpath nylon block 4 if too sharply, wear and tear two tube core materials that increase between the footpath nylon block 4 easily, consequently, increase the edge of footpath nylon block 4 and be formed with the fillet in order to realize gentle transition.
As shown in fig. 3, because it is more to rise locking screw 7 on the axle 1 outer wall, increase the nylon block 4 accurate positioning on the axle 1 outer wall that rises for convenient, increase and be equipped with location structure 9 between the nylon block 4 and the axle 1 that rises, location structure 9 is used for keeping the alignment state of guiding hole 6 and locking screw 7, and the fastening screw 5 of being convenient for can smoothly be connected with corresponding locking screw 7 behind the guiding hole 6.
When increasing a footpath nylon piece 4 in the installation, the staff will increase a footpath nylon piece 4 laminating and be in locating hole 92 on increasing axle 1 surface until lug 91, alright realize increasing a footpath nylon piece 4 evenly distributed on increasing axle 1's outer wall to make guiding hole 6 keep aliging with locking screw 7, the installation of the locking screw of being convenient for.
Combine actual installation experience, location structure 9 still can adopt the locating lever of independent setting, the length of locating lever is greater than the length sum of guiding hole 6 and locking screw 7, the quantity of locating lever sets up a plurality ofly, the locating lever is movable earlier and is inserted and establish in locking screw 7, later, increase the guiding hole 6 on the nylon block 4 and pass the locating lever, until increasing the laminating of nylon block 4 and expanding on axle 1, take away the locating lever again, immediately with fastening screw 5 install in locking screw 7 can.
When increasing the footpath nylon piece 4 of different specifications need be changed, only need through work piece alright unscrewing fastening screw 5 such as automatic screw locking instrument to pull down and increase footpath nylon piece 4, the same reason, the installation is new increases footpath nylon piece 4, through work piece locking fastening screw 5, thereby will increase footpath nylon piece 4 and fix on rising axle 1, reasonable in design, convenient operation.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the fan belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that modifications and embellishments within the scope of the present disclosure may be made by those skilled in the art without departing from the principles of the present disclosure.
