Abstract

The invention discloses a detachment tool special for a ratchet looseness resistant fastener and belongs to the field of machinery installation. In the process of assembly of various large-scale mechanical devices, especially some important components which are connected through bolts, looseness resistance is achieved in the mode that ratchet nuts and ratchet spring pads are combined. The specificity of the structure determines that the locking nuts have the feature of irreversibility. If the locking nuts are forcedly detached, the ratchet spring pads can be certainly damaged. If the workload of maintenance and overhauling is heavy, large waste can be certainly caused, and unnecessary economic cost can be increased. The detachment tool special for the ratchet looseness resistant fastener aims to overcome the defects of the prior art. The detachment tool special for the ratchet looseness resistant fastener is composed of a gland and a ratchet wheel socket spanner. The gland is a special gland provided with inner-hole threads. The ratchet wheel socket spanner is a special and dedicated ratchet wheel socket spanner. The detachment tool special for the ratchet looseness resistant fastener solves the problem that the looseness resistant fastener is difficult to detach, and avoids the phenomenon that the ratchet spring pads are damaged.

Description

A kind of ratchet anti-loose fastener removal tool special

Technical field

The invention belongs to mechanical erection field, relate in particular to a kind of ratchet anti-loose fastener removal tool special.

Background technology

In the assembling of various heavy mechanical equipments, locking security measure is absolutely necessary, some important components with bolts particularly, are all in the mode of ratchet nut and the combination of ratchet spring pad, to carry out lockingly, and this class formation is also impeccable to the anti-loosing effect of bolt; But the particularity of this structure has also determined locking nut and has had irreversible this feature, if dismantle by force, ratchet spring pad will inevitably be damaged and can not use again, can only more renew part, brought inconvenience so just to maintenance and the maintenance of equipment, if the workload of safeguarding and overhauling is larger, will inevitably cause great waste, increase unnecessary financial cost.

Ratchet structure has the feature of one-way movement. as got involved without special external force, its direction of motion is irreversible, therefore the top priority of dismounting is exactly to make ratchet spring pad under the prerequisite not being destroyed, lose retaining effect, but because spring pad is many ratchet structures, so adopt common extracting tool to be difficult to find suitable impetus; Separated ratchet must complete with the action of moving back the jack panel that uncages simultaneously, two hands of a people, are used common extracting tool reluctantly that ratchet structure is separated, but can not complete again the action of moving back the jack panel that uncages simultaneously, in addition the limitation of operating space more makes dismounting cannot complete at all.

Summary of the invention

Be directed to prior art deficiency, the invention provides a kind of ratchet anti-loose fastener removal tool special, solve a dismounting difficult problem for the ratchet anti-loose fastener of knowing clearly, stopped again to damage the phenomenon of ratchet spring pad.

In order to achieve the above object, the present invention is by the following technical solutions: a kind of ratchet anti-loose fastener removal tool special, gland and box socket set, consist of, wherein gland is the special gland with inner hole thread, and box socket set is special special-purpose box socket set.

An anti-loose fastener removal tool special, borrows original bolt to match with the special gland with inner hole thread, can reach make the ratchet structure object of separation gradually by turning clockwise; Special-purpose box socket set, an end face of sleeve and special gland are in contact with one another and can form and be slidably matched, and the other end of sleeve acts directly on the ratchet of spring pad.

The invention has the beneficial effects as follows: this specific purpose tool has solved the quick-detachment problem of ratchet anti-loose fastener, box socket set can be for convenience detach, to change the sleeve of different size, upset box socket set can meet the requirement of different rotary direction, because split ratchet spring pad is not impaired, so can be repeatedly used, saved greatly cost, avoided unnecessary waste.

Accompanying drawing explanation

Fig. 1 is the structural representation of gland.

Fig. 2 is the structural representation of box socket set.

Fig. 3 is ratchet anti-loose fastener removal tool special dismounting principle schematic.

In figure: 1, sleeve, 2, split nut, 3, split workpiece, 4, gland, 5, box socket set, 6, ratchet spring pad.

The specific embodiment

An anti-loose fastener removal tool special, is comprised of gland 4 and box socket set 5, and wherein as shown in fig. 1, gland 4 is the special gland with inner hole thread; As shown in Figure 2, box socket set 5 is special special-purpose box socket set.

An anti-loose fastener removal tool special, borrows original bolt to match with the special gland 4 with inner hole thread, can reach make the ratchet structure object of separation gradually by turning clockwise; Special-purpose box socket set 5, an end face of sleeve 1 is in contact with one another also and can forms and be slidably matched with special gland 4, and the other end of sleeve 1 acts directly on the ratchet of spring pad.

Unloading process is with reference to shown in Fig. 3, first select suitable box socket set 5 to be enclosed within on split nut 2, then the gland 4 that turns clockwise makes the sleeve of spanner press to ratchet spring pad 6, when the ratchet structure of spring pad loses retaining, do the used time, can being rotated counterclockwise box socket set 5, to make split locking nut pine retreat to dismounting complete.

Claims

1. a ratchet anti-loose fastener removal tool special, is characterized in that: gland (4) and box socket set (5), consist of, gland (4) is the special gland with inner hole thread; Box socket set (5) is special special-purpose box socket set.

2. a kind of ratchet anti-loose fastener removal tool special according to claim 1, is characterized in that: borrow original bolt to match with the special gland (4) with inner hole thread, can reach make the ratchet structure object of separation gradually by turning clockwise; Special-purpose box socket set (5), an end face of sleeve (1) and special gland (4) are in contact with one another and can form and be slidably matched, and the other end of sleeve (1) acts directly on the ratchet of spring pad.
