Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary installation of clip springs, in particular to an auxiliary installation tool for clip springs. Background Art

[0002] 90° circlip pliers are usually used to install circlips for shafts. When limiting the circlip at the top of the rotating shaft, since the top of the circlip pliers is a 90° structure, after the circlip is installed using the circlip pliers, there will be a certain distance between the tip of the circlip pliers and the shaft cover, resulting in the circlip being unable to be directly connected to the circlip groove on the outside of the shaft. This situation may also occur when installing circlips for partial holes. If you do not notice that the circlip is installed in the wrong position, it will affect the normal use of the machine. Utility Model Content

[0003] The technical problem to be solved by the utility model is that when the existing circlip is installed, the circlip pliers are inconvenient to install the circlip in place, especially when there is a blocking structure on one edge of the circlip groove.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is a spring-assisted installation tool, including a grip rod, a plurality of arc-shaped grooves are opened at one end of the grip rod, an arc-shaped ring groove is opened inside the arc-shaped groove, an adjustment cap is provided at one end of the grip rod, a plurality of arc-shaped through holes are opened on one side of the adjustment cap, a pressure rod is provided in the arc-shaped groove, a limiting ring platform is fixed on the outer side of one end of the pressure rod in the arc-shaped ring groove, one end of the pressure rod passes through the arc-shaped through hole, a threaded hole is opened at one end of the grip rod, and a threaded rod is fixed on the inner side of the adjustment cap in the threaded hole.

[0005] As a further solution of the utility model: the rotation direction of the arc-shaped through hole is opposite to the rotation direction of the arc-shaped notch, and the adjusting cap is rotated to drive a plurality of pressure rods to move simultaneously, thereby adjusting the positions between the plurality of pressure rods simultaneously.

[0006] As a further solution of the utility model: the length of the pressure rod is greater than the maximum arc length of the arc-shaped notch, so as to ensure that the pressure rod can be pressed to the position of the retaining spring.

[0007] As a further solution of the utility model: the width of the arc-shaped through hole is equal to the width of the arc-shaped slot, which can prevent the pressure rod from generating unnecessary shaking.

[0008] As a further solution of the utility model: the pressure rod is made of high-strength steel to ensure the strength of the pressure rod and prevent it from being deformed.

[0009] Compared with the prior art, the utility model has the following advantages: the utility model adds a plurality of pressure rod structures, which can facilitate pushing the retaining spring so that it can be snapped into place, and through the cooperation between the arc-shaped grooves and the arc-shaped through holes in different directions, the positions of the plurality of pressure rod structures can be controlled to adapt to retaining springs of different sizes.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides a technical solution to solve the existing problems raised in the background technology.

[0019] In combination with attachments 1-4, it can be known that the device includes a grip rod 1, a plurality of arc-shaped notches 1.1 are provided at one end of the grip rod 1, an arc-shaped annular groove 1.2 is provided inside the arc-shaped notch 1.1, an adjustment cap 2 is provided at one end of the grip rod 1, a plurality of arc-shaped through holes 2.1 are provided on one side of the adjustment cap 2, a pressure rod 3 is provided in the arc-shaped notch 1.1, a limited ring platform 3.1 is fixed on the outer side of one end of the pressure rod 3 in the arc-shaped annular groove 1.2, one end of the pressure rod 3 passes through the arc-shaped through hole 2.1, a threaded hole 1.3 is provided at one end of the grip rod 1, and the rotation direction of the arc-shaped through hole 2.1 is parallel to that of the arc-shaped notch 1. .1 The rotation direction is opposite to that of the adjusting cap 2, so as to drive several pressure rods 3 to move simultaneously by rotating the adjusting cap 2, thereby adjusting the positions of several pressure rods 3 at the same time; the length of the pressure rod 3 is greater than the maximum arc length of the arc-shaped slot 1.1, so as to ensure that the length of the pressure rod 3 can press the position of the retaining spring; a threaded rod 2.2 is fixed in the threaded hole 1.3 on the inner side of the adjusting cap 2; the width of the arc-shaped through hole 2.1 is equal to the width of the arc-shaped slot 1.1, which can prevent the pressure rod 3 from producing unnecessary shaking; the pressure rod 3 is made of high-strength steel to ensure the strength of the pressure rod 3 and prevent it from deformation.

[0020] The working principle of the present application is as follows: when installing the circlip, first use the circlip pliers to stretch or compress the circlip, and then place it in the circlip groove. If the circlip cannot be completely inserted into the circlip groove due to the obstruction of the circlip pliers tip, the tool can be used for auxiliary installation;

[0021] First, rotate the adjusting cap 2 to drive the arcuate through hole 2.1 to rotate, so as to drive the pressure rod 3 to move. Because the limiting ring platform 3.1 at one end of the pressure rod 3 is located in the arcuate ring groove 1.2, and the rotation direction of the arcuate through hole 2.1 is opposite to that of the arcuate notch 1.1, the distances between several pressure rods 3 will change synchronously to adapt to the diameters of different retaining rings. After adjustment, because it is tightened with the threaded hole 1.3 and the threaded rod 2.2, the position can be fixed after loosening the adjusting cap 2, and then the retaining ring is pressed into the retaining ring groove by several pressure rods 3. A click is heard, which is the sound of the retaining ring hitting the inside of the retaining ring groove, and the retaining ring can be installed in this way.

[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
