Detailed Description

The technical scheme in the embodiment of the application is for solving the striking instrument that the lock nut who dismantles on the adapter sleeve now adopted and to its atress uneven and difficult problem of dismantling it when beating, and the general thinking is as follows:

example 1:

referring to fig. 1, a T-shaped cylinder dismantling device for use by a user comprises a chip removal chain shaft head bearing tensioning member 10 and an auxiliary striking dismantling member 20. The chip removal chain shaft head bearing tensioning member 10 is a combined structure for assisting the chip removal chain transmission shaft to rotate on a machine tool in the prior art; the auxiliary knock-out member 20 is used to knock the lock nut 110 to assist in the disassembly of the double row ball inner cone bearing 120.

Referring to fig. 1, 3-5, the chip removal chain stub bearing tensioning member 10 includes a lock nut 110. The locking nut 110 is used for positioning and locking the adapter sleeve 130 in the chip removal chain axle head bearing tensioning member 10, and indirectly fixing the double-row ball inner cone bearing 120.

The chip removal chain shaft head bearing tensioning member 10 specifically comprises a double-row ball inner cone bearing 120, a clamping sleeve 130 and a thrust pad 140, wherein the clamping sleeve 130 is supported on an inner ring of the double-row ball inner cone bearing 120 and sleeved on an outer ring of a chip removal chain drive shaft of a machine tool, an inner ring of the thrust pad 140 is sleeved on an outer ring of the clamping sleeve 130, an inner convex block of the thrust pad is clamped at a gap of the clamping sleeve 130, the locking nut 110 is also fixed on the outer ring of the clamping sleeve 130, and an outer convex block of the thrust pad 140 is clamped at a gap of an outer ring of the locking nut 110. When the chip removal chain transmission shaft and the chip removal chain head bearing tensioning member 10 are installed, the retaining sleeve 130 is sleeved on the outer ring of the chip removal chain transmission shaft, the double-row ball inner taper bearing 120 is sleeved on the outer ring of the retaining sleeve 130, the thrust pad 140 is sleeved on the outer ring of the retaining sleeve 130, the inner convex block is clamped at the gap of the retaining sleeve 130, and the locking nut 110 is screwed on the thread of the outer ring of the retaining sleeve 130.

It should be further noted that the adapter sleeve 130 has a step edge and is integrally tapered, the double-row ball inner cone bearing 120 and the lock nut 110 are respectively located at two sides of the step edge of the adapter sleeve 130 and respectively close to the large-caliber end and the small-caliber end thereof, as shown in fig. 3, so that when the lock nut 110 is knocked, the double-row ball inner cone bearing 120 relatively moves to the small-caliber end of the adapter sleeve 130, thereby facilitating the detachment thereof

Referring to fig. 1 and 3, the auxiliary knock-out member 20 includes a cylinder 210 and a steel plate 220 fixed to one end of the cylinder, and the diameter of the open end of the cylinder 210 is the same as that of the lock nut 110, and can assist the impact of a hammer to be knocked on the lock nut 110. The cylinder 210 and the lock nut 110 have the same diameter, so that the cylinder 210 is more suitable for a smaller knocking and detaching space under the condition of ensuring uniform stress during force application.

The hammer to be struck acts directly on the outer end face of the steel plate 220. The steel plate 220 is designed to facilitate a hammer to apply a force to the cylinder 210 so as to uniformly knock the outer end surface of the lock nut 110.

The cylinder 210 is specifically No. 45 steel having a length of 200mm and a diameter phi of 50.

The steel plate 220 is specifically a No. 45 steel plate with a size of 60 × 60. Wherein, the length and width size of steel sheet 220 is greater than the drum 210 diameter, and the effect face that the hammer directly beaten is the outer section of steel sheet 220, and beats the in-process operator hand and can hold drum 210, so reduced the probability that the hammer accidentally injured the operator hand.

The steel plate 220 is fixed to one end of the cylinder 210 by welding. Wherein, its two wholly constitute T shape drum instrument, and the junction adopts welded fastening for this assembly and disassembly tools's structural strength is higher, has indirectly promoted its life.

Rubber pads 230 are bonded to the steel plate 220 and the cylinder 210 at the ends that are spaced apart. The rubber pad 230 is fixed at the end where the steel plate 220 and the cylinder 210 are separated from each other by means of strong glue, and in the process that the lock nut 110 is knocked, the probability that the outer end of the steel plate 220 is directly stressed to deform can be reduced by means of the buffer protection effect of the rubber pad 230, the probability that the contact surface of the lock nut 110 and the cylinder 210 is stressed to deform can also be reduced, the service life of the disassembling tool is indirectly prolonged, and meanwhile, the integrity of the lock nut 110 is effectively protected.

Meanwhile, the anti-slip pad made of rubber is adhered to the hand-held part on the outer wall of the cylinder 210, the friction force of the hand-held part can be increased by means of the design of the anti-slip pad, the holding stability of the tool is improved, meanwhile, the anti-slip pad has a certain elastic damping effect, and the discomfort caused by tool vibration in the knocking process can be reduced.

When in use:

firstly unscrewing a plurality of circles of locking nuts 110, then attaching the opening end of the cylinder 210 to the outer end face of the locking nut 110, directly knocking the steel plate 220 by a hammer to promote the more uniform force application of the cylinder 210 to knock the locking nut 110, and under the condition that the locking nut 110 is knocked by more uniform force, driving the adapter sleeve 130 which is propped at the inner ring of the double-row ball inner cone bearing 120 to uniformly retreat along the chip removal shaft to promote the double-row ball inner cone bearing 120 to be moved to the position of the step edge of the adapter sleeve 130, so that the double-row ball inner cone bearing 120 can be conveniently and directly taken down.

Compared with the traditional method of striking the lock nut 110 by a crowbar and a hammer, as shown in fig. 2, the force is more uniform, the probability of deviation striking is reduced, and the disassembly time is relatively greatly shortened.

Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. And obvious variations or modifications are intended to be within the scope of the present invention.
