Description

Adjustable limiting assembly device for elastic retainer ring

Technical Field

The utility model relates to the technical field of machining, in particular to an adjustable limiting assembly device for an elastic retainer ring.

Background

Currently, in the mechanical product, referring to fig. 1 to 3, in order to prevent the radial mounting part 1-2 mounted on the mounting shaft 1-1 from moving axially, an annular groove 1-4 may be formed at a corresponding position (e.g., beside the mounting position 1-3 of the radial mounting part) on the mounting shaft 1-1, and a circlip 1 as a standard member may be mounted at the position of the annular groove 1-4, and the circlip 1 may function to prevent the axial movement of the on-shaft part (i.e., the radial mounting part 1-2) so as to limit the radial mounting part 1-2 to a predetermined position.

The circlip 1 is used as an annular sheet workpiece, the inner diameter of the circlip 1 is slightly smaller than the outer diameter of the assembly shaft 1-1, in order to install the circlip 1 on the assembly shaft 1-1, two retainer holes 101 on the circlip 1 need to be expanded (i.e. spread open) firstly, so that the two retainer holes 101 are relatively spread, and the opening 102 of the circlip is expanded, and then the circlip 1 is clamped on the pre-processed annular groove 1-4 on the assembly shaft 1-1;

However, in the existing installation method, a worker determines the size of the distance between the two collar holes 101 on the circlip 1 that are expanded (i.e., the size of the expanded space) by visual inspection, so that the requirement on the working experience of the worker is high, and in the process of expanding the two collar holes 101 on the circlip 1, the expanded space is easily oversized, so that the circlip 1 exceeds the elastic limit and the yield limit of the worker, and finally the circlip 1 fails.

If the worker does not find the failure problem of the circlip 1 in time at the time of installation, but continues to use the failed circlip 1, the failed circlip 1 easily falls off from the assembly shaft 1-1 under the vibration of the machine operation when the machine with the assembly shaft installed is operated, thereby causing a safety accident.

Therefore, there is an urgent need to develop a technology capable of solving the above technical problems.

In the utility model, the limit adjusting mechanism 100 comprises a lantern ring 3, a stud 4, a thread bush 5 and a hexagonal nut 6;

The other end of the threaded sleeve 5 is disposed opposite to the second bias handle 2022 toward one side (i.e., the inner side) of the first bias handle 2021.

The first and second jaws 2031 and 2032 are inserted into the two collar holes 101 of the circlip 1 to expand the opening 102 of the circlip 1, thereby clamping the circlip 1 to the pre-machined annular groove 1-4 on the assembly shaft 1-1;

With the present utility model, a worker applies a gripping force to the two force applying handles by hand, and converts a gathering force formed by a relative movement between the two force applying handles into a tension force expanding outwards (i.e. a driving force of a back-to-back movement) between the two jaws of the first jaw 2031 and the second jaw 2032 by means of the jaw shaft 201, wherein during the process of applying the gripping force to the two force applying handles, the spacing between the first force applying handle 2021 and the second force applying handle 2022 (i.e. the spacing distance between the two force applying handles shown in fig. 4) is controlled by the spacing adjustment mechanism 100 due to the existence of the spacing adjustment mechanism 100, so that the excessive expansion dimension between the two force applying handles due to the excessive amplitude of the relative movement of the two force applying handles is avoided, and the excessive expansion dimension of the opening 102 of the circlip 1 is avoided, and the circlip 1 is prevented from exceeding the elastic limit and yielding limit of the circlip 1.

In particular, collar 3 comprises a ring 301 and a fixed end 303, which are connected to each other;

The inside of the ring body 301 is provided with a transversely distributed force application handle accommodating through hole 302;

A force-applying handle accommodation through hole 302 for passing through the first force-applying handle 2021 or the second force-applying handle 2022 (shown in fig. 4 as passing through the first force-applying handle 2021);

The inside of the fixed end 303 is provided with stud installation internal threaded holes 304 which are vertically distributed;

The stud mounting internal threaded hole 304 is directly communicated with the force application handle accommodating through hole 302;

One end of the stud 4 is located in the stud mounting female screw hole 304, and is screwed with the stud mounting female screw hole 304, and the end terminal portion of the stud 4 is in abutting contact (i.e., is abutted) with the first application handle 2021 or the second application handle 2022 penetrating through the application handle accommodating through hole 302.

Further, one end of the stud 4 is screwed with the stud mounting internal threaded hole 304 of the fixed end 303, and then is further screwed with a hexagonal nut 6, and the hexagonal nut 6 is in abutting contact with the side surface of the fixed end 303;

further, the other end of the stud 4 is in threaded connection with an internal threaded hole at one end of the threaded sleeve 5;

The other end of the stud 4 is also in threaded connection with another hexagonal nut 6, and the hexagonal nut 6 is in tight contact with one end side surface of the threaded sleeve 5.

In particular, the central axis of the stud-mounting internal threaded hole 304 is perpendicular to the central axis of the force-applying handle-receiving through hole 302.

Further, the ring 301 and the fixed end 303 are integrally formed.

Further, the stud 4 is a columnar part with a whole thread;

It should be noted that, for the present utility model, one end of the stud 4 is screwed into the threaded sleeve 304 and is locked by one hexagonal nut 6, and the other end is screwed into one end of the threaded sleeve 5 and is locked by the other hexagonal nut 6;

The thread sleeve 5 is a long annular part with full threads inside;

For the present utility model, the size of the external thread of the stud 4 matches the size of the internal thread of the stud mounting internal threaded hole 304 and the size of the internal thread of the threaded sleeve 5;

For the present utility model, the length of collar 3, stud 4 and threaded sleeve 5 is designed according to the dimension L' by which the two jaws need to be spread apart (i.e. the dimension of the spacing between the two collar holes 101 in circlip 1 when they need to be mounted on the mounting shaft in the state in which circlip 1 is not spent, i.e. the preset working range of the device of the present utility model), and the spacing between the two forcing handles, first forcing handle 2021 and second forcing handle 2022. The lengths of the collar 3, the stud 4 and the thread bush 5 are comprehensively designed according to the distance between the first force application handle 2021 and the second force application handle 2022, so that the adjustable range can meet the use requirement.

The dimension L' by which the two jaws need to be opened is a distance dimension (i.e., a linear distance between the two axes) by which the axes of the two retainer holes 101 in the circlip 1 are spread when the circlip 1 is required to be attached to the assembly shaft in a state in which the circlip 1 is not in failure.

In particular, the L' dimension is preferably: the minimum distance between the axes of the two ring holes 101 when the circlip 1 can be mounted on the assembly shaft 1-1 is enough to smoothly mount the circlip 1 on the assembly shaft, so that the circlip 1 can be ensured to have good elasticity.

In particular, when the device of the utility model is used for the first time, the limit distance dimension (which can be measured by a caliper) between two force application handles in the device can be adjusted from large to small, and trial assembly is performed for many times, when the circlip 1 can be just mounted on the assembly shaft, the distance between the axes of the two circlips 101 is equal to the minimum distance L '(which can be measured and confirmed by the caliper) between the axes of the two circlips 101 when the circlip 1 can be mounted on the assembly shaft, the hexagonal nut of the device is locked, the distance of the limit distance dimension between the two force application handles is locked, and meanwhile, the limit distance dimension between the two force application handles is measured and recorded by the caliper to be equal to H (H can be called as a standard limit distance dimension), and then when the device is used again, even if an operator uses a larger force, the distance of the circlip 1 which is opened is a fixed value L', and the circlip 1 is not excessively opened at the moment, and is in a good use state in theory; the circlip 1 that fails when subjected to the impact of radial blow-by force may fall off the assembly shaft 1-1.

In addition, it should be noted that if the circlip fails, the inner side aperture of the failed circlip is larger than that in the initial state, and the inner side aperture of the non-failed circlip can rebound to the initial state after being expanded;

The verification operation adopted by the elastic retainer ring for failure can be specifically verified by measuring the distance between the axes of the two retainer ring holes 101 through a caliper, and after the elastic retainer ring is stretched, if the distance between the axes of the two retainer ring holes 101 is rebound to be equal to the distance between the axes of the two retainer ring holes 101 in the initial state (i.e. the uninstalled state), no failure is indicated, otherwise, if the distance between the axes of the two retainer ring holes 101 of the elastic retainer ring is larger than the distance between the axes of the two retainer ring holes 101 in the initial state (i.e. the uninstalled state), the failure is indicated.

In the present utility model, the circlip 1 is made of metal.

In order to more clearly understand the technical scheme of the present utility model, the working process of the present utility model is described below.

In the first step, a force application handle (taking the first force application handle 2021 as an example, of course, in practical application, any handle may be used, for example, the second force application handle 2022 may also be used) is inserted through the force application handle accommodating through hole 302 on the ring 301 of the collar 3;

Secondly, rotating the stud 4, enabling the stud 4 to pass through the stud mounting internal threaded hole 304 on the lantern ring 3, enabling one end close to the force application handle accommodating through hole 302 to abut against the force application handle (specifically, the first force application handle 2021), screwing the hexagonal nut 6 at the end, and fixing one end of the limit adjustment mechanism 100 on the force application handle (specifically, the first force application handle 2021);

Thirdly, rotating the threaded sleeve 5 at the other end of the adjusting stud 4, so that when the outer end of the threaded sleeve 5 is just propped against the other force application handle, the limit distance between the two force application handles is equal to the standard limit distance dimension H (the distance can be measured by a caliper), and when the distance is equal to L '(namely the dimension L' of the two jaws required to be opened, the hexagonal nut 6 close to the threaded sleeve 5 is screwed at the moment, thereby locking the two force application handles, keeping the limit distance between the two force application handles equal to the standard limit distance dimension H unchanged, so that the limit adjusting mechanism 100 can be positioned and installed conveniently for later use when the elastic retainer ring is opened;

The size of the limiting distance between the two force application handles is as follows: the distance between the two ends of the limit adjusting mechanism 100 in the device of the utility model and the mounting positions of the two force application handles is the distance between the two force application handles and the inner arc tangent line at the connecting positions of the two ends of the limit adjusting mechanism 100.

The standard limiting distance dimension H between the two force application handles is specifically: when the two jaws are opened to a size equal to: when the circlip 1 can be mounted on the assembly shaft, the minimum distance L '(i.e. the dimension L' of the two jaws that need to be opened) between the axes of the two circlips 101 is the distance between the mounting positions of the two ends of the limit adjustment mechanism 100 on the two force application handles (i.e. the distance between the two force application handles and the inner arc tangents at the connecting positions of the two ends of the limit adjustment mechanism 100).

As regards the adjustment operation of the device according to the utility model, it is possible in particular to: the worker holds two force application handles by one hand, rotates the threaded sleeve 5 by the other hand to properly adjust the length of the device, holds the two force application handles again, measures the limit distance between the two force application handles by using a caliper, and repeatedly operates until the limit distance between the two force application handles is adjusted to be equal to the standard limit distance H, so that the actual opening size of the two clamp mouths is adjusted to be equal to L'.

Fourth, for a circlip 1 to be mounted on the mounting shaft, in order to mount the circlip 1, two circlips holes 101 on the circlip 1 need to be spread to expand the opening 102, for this reason, the worker does not hold the two handles with two force-applying handles tightly, but first opens outwards (i.e. moves back to back), so that the two handles with the first and second handles 2031 and 2032 move relatively (i.e. are in a tendency of clamping inwards), the two handles are inserted into the two circlips holes 101 of the circlip 1 in a natural state (i.e. in a non-spread state), then the worker applies a holding force to the two force-applying handles by hand, and converts the force-gathering formed by the relative movement between the two force-applying handles into a tension (i.e. a driving force of back to back) expanding outwards between the two handles with the first and second handles 2031 and 2032, wherein during the process of applying the holding force to the two handles, the sleeve 5 and the adjacent handles with the existence of the limit adjusting mechanism 100 can keep the limit distance L 'to be equal to the maximum dimension L' and the limit distance L 'between the two handles is kept as the limit distance L' is equal to the maximum dimension and the limit distance L is not equal to the limit distance L;

That is, with the present utility model, due to the presence of the limit adjustment mechanism 100, when the installation between the circlip 1 and the fitting shaft is performed, the dimension of the two retainer holes 101 of the circlip 1 that are spread by the two jaws can be subjected to a controllable, quantized adjustment limit, that is, equal to the preset dimension L'.

Therefore, the limit adjusting mechanism is specially designed, so that the problem that the opening size between the two clamp mouths 2031 and 2032 is overlarge due to overlarge amplitude of relative movement of the two force application handles can be effectively avoided, the opening size of the opening 102 of the circlip 1 is prevented from being overlarge, and the circlip 1 is prevented from being invalid due to the fact that the circlip 1 exceeds the elastic limit and the yield limit of the circlip.

Compared with the prior art, the adjustable limiting assembly device for the circlip has the following beneficial effects:

1. According to the utility model, the limiting and adjusting mechanism 100 is arranged between the two force application handles, so that the opening size of the two clamp mouths can be indirectly controlled to be a preset size, and the working difficulty of an operator is reduced;

2. According to the utility model, the limit distance between the two force application handles can be adjusted by adjusting the position of the threaded sleeve 5 on the stud 1, so that the limit distance between the two force application handles is equal to the standard limit distance H, and the maximum dimension of the actual opening of the two clamp nozzles is adjusted to be equal to L '(namely, the opening dimension L' of the two clamp nozzles is required), so that the assembly requirements of circlips with different specifications and sizes are met;

3. For the utility model, because the two force application handles are vertically symmetrically distributed and are formed by intersecting a plurality of cambered surfaces, the relative positions of the limiting and adjusting mechanism 100 and the handles can be adjusted according to the needs to indirectly adjust the opening sizes L' of the two clamp mouths;

4. by applying the utility model, the installation problem of the elastic check rings with different specifications is solved;

5. The utility model has reasonable structure, convenient and quick operation and accurate and reliable assembly precision, greatly improves the working efficiency and ensures the assembly quality of the elastic retainer ring.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
