Description
Technical field
The utility model relates to a kind of extracting tool, particularly a kind of shaft coupling dismounting specific purpose tool.
Background technology
3CC reach the standard grade roller-way be with about 20 tons hot steel billet by fiery clear be delivered to Wide and Thick Slab factory must be through carrying tie.Therefore the quality of the equipment performance of rollgang is and is important.Especially the shaft coupling of rollgang high speed shaft, frequency of utilization is very big.Its structural design more complicated, brake apparatus and shaft coupling are designed to the form of one, and this coupling bolt is driving fit bolt, and bolt cooperates very tight with screwed hole.Shaft coupling connecting bolt dismounting space is very narrow and small, and after the dismounting nut, also needs to tap bolt with copper rod.Because bolt cooperates with screwed hole closely, causes the damage of screw thread in the process of beaing easily, even in dismounting, damage shaft coupling and braking brake dish.So, by the variety of issue of above existence, ad hoc meter roller-way shaft coupling dismounting specific purpose tool.
Because the defective that above-mentioned existing dismounting mode exists, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and practice in addition, in the hope of creating the shaft coupling dismounting specific purpose tool that dismounting is more convenient, reduce the coupling bolt spoilage.Constantly study, test and improve through the inventor, create the present invention.
The utility model content
The technical problems to be solved in the utility model provides a kind of use shaft coupling dismounting more easily specific purpose tool, and is convenient in the small space dismounting, reduced the spoilage of driving fit bolt.
For solving the problems of the technologies described above, the utility model shaft coupling dismounting specific purpose tool, comprise clamp ring of forming by the two halves loop configuration and the fixture of fixing described clamp ring, unthreaded hole and screwed hole are set on clamp ring, one straight-bar is set in described unthreaded hole, the dismounting end of described straight-bar 5 is provided with ut socket, and a screw rod is set in the described screwed hole.
Preferably, the dismounting end of straight-bar is provided with a snap joint, is with ut socket in the snap joint.The purpose of snap joint is set, and is when the coupling bolt of dismounting different size, can put corresponding specifications of nuts sleeve in snap joint.Can strengthen the versatility of this shaft coupling extracting tool like this.
Preferably, the straight-bar other end is provided with a turret head.When rotating straight-bar with instruments such as spanners, a turret head is set, can be more laborsaving, reach the effect of getting half the result with twice the effort.
Preferably, fixture is four contiguous blocks of fixedlying connected with the two halves loop configuration, and contiguous block is connected by bolt.
After adopting such structure, more convenient at small space dismounting coupling bolt, reduced the spoilage of coupling bolt to be removed.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the front view of the utility model shaft coupling dismounting specific purpose tool.
Fig. 2 is the vertical view of the utility model shaft coupling dismounting specific purpose tool.
Fig. 3 is the side view of the utility model shaft coupling dismounting specific purpose tool.
The specific embodiment
The utility model shaft coupling dismounting specific purpose tool comprises the clamp ring of being made up of the semi-circular structure of two symmetries 1, and clamp ring 1 is made according to the dimensional measurement of shaft coupling end diameter.Respectively be welded with a fixture 2 at the two ends of two semi-circular structures, fixture 2 can be four contiguous blocks 21, leaves a M16 screwed hole 4 in the middle of the contiguous block 21.When clamp ring 1 is clipped in the shaft coupling end, connect, play clamping ring 1 with M16 bolt 22.
After the measurement shaft coupling waits to tear open the bolt reference diameter, on clamp ring 1 according to waiting that reference diameter and the distributing position of tearing bolt open make two groups of unthreaded holes 3 and screwed hole 4, unthreaded hole 3 in every group and screwed hole 4 be angle with rational at interval, unthreaded hole 3 and screwed hole 4 angle at interval is identical in two groups, and is symmetrically distributed at two parts of clamp ring 1 respectively.Unthreaded hole 3 sizes are fixed according to the size of straight-bar 5, and screwed hole 4 sizes are fixed according to the size of screw rod 6.
The straight-bar 5 of respectively packing in unthreaded hole 3, these straight-bar 5 one ends are welded with a hexagonal snap joint 51, and ut socket 53 is enclosed within the snap joint 51.The other end of straight-bar 5 is welded with a turret head 52.This device is used to dismantle the shaft coupling nut.With the nut of ut socket 53 aligning coupling bolts, the turret head 52 of rotation straight-bar 5 drives ut socket 53 and rotates, and pulls down the shaft coupling nut.
The screw rod 6 of in screwed hole 4, respectively packing into.This device is used to dismantle coupling bolt.Screw rod 6 is aimed at coupling bolt, and rotary screw 6 can slowly eject shaft coupling with coupling bolt.
Dismounting is during shaft coupling, and the ring type structure of upper and lower two semi-circular compositions is enclosed within the shaft coupling end, and fixture 2 is fixed on the shaft coupling, in the time of fixedly, makes nut to be removed on the ut socket 53 aligning shaft couplings, and jacket casing is on nut.With the rotation turret head 52 of spanner straight-bar 5 other ends, drive ut socket 53 rotations by straight-bar 5, and then unload lower nut.Owing to also be provided with a straight-bar 5 in symmetric position, so this group straight-bar 5 and screw rod 6 have also been aimed at corresponding nut on the shaft coupling, adopt in the same way, unload lower nut.Unclamp the fixture 2 of anchor clamps then, rotate a certain angle, make screw rod 6 aim at the coupling bolt of just having pulled down nut, extracting tool is fixed on the shaft coupling by fixture 2.Rotary screw 6 slowly ejects coupling bolt.Because second group of angle that straight-bar 5 is identical at interval with screw rod 6 is so second group of screw rod 6 also aimed at bolt on the shaft coupling.Rotary screw 6 can slowly eject shaft coupling with coupling bolt equally.
Unclamp fixture 2,, make the ut socket 53 of straight-bar 5 aim at nut next to be removed, adopt, pull down nuts and bolt respectively with aforementioned identical dismounting mode with clamp ring 1 rotating certain angle.The rest may be inferred, bolts all on the shaft coupling can be pulled down.So both improve efficient, reduced the damage of coupling bolt again.
The straight-bar 5 and being provided with of screw rod 6 that are used for demounting bolt can also be adopted other set-up modes, as one group of straight-bar 5 and screw rod 6 only are set, three groups of straight-bars 5 and screw rod 6 are set perhaps, set according to the distributing position of coupling bolt, are not limited to above-mentioned set-up mode.
After adopting such structure, following beneficial effect is arranged:
(1) ut socket 53 is fixed on the clamp ring 1, conveniently dismantles at narrow space.
(2) saved manpower, the work that originally need to be finished by eight people only needs a four-player just can finish after adopting this extracting tool.
(3) reduced bolt failure rate on the shaft coupling.
(4) shorten the take-down time, improved operating efficiency.
