Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling, in particular to a handheld hole-free retaining ring installation device. Background Art

[0002] In the current new energy electric drive products, the wire retaining ring is one of the key parts for the installation and fixation of the drive half-shaft. Different equipment manufacturers will design relevant assembly equipment according to the product conditions. Since the wire retaining ring lacks auxiliary process holes such as retaining spring holes compared to conventional retaining springs, there is a lack of universal and suitable equipment for its installation.

[0003] Existing auxiliary tooling usually uses the following methods to complete the installation of the retaining ring:

[0004] 1. Use automated equipment with cylinders or servo motors as the power for press-fitting; however, the use of automated equipment with cylinders or servo motors as the power for press-fitting has high equipment costs, long equipment design cycles, low product compatibility, and poor versatility, making it difficult to achieve rapid changeover in the context of flexible production.

[0005] 2. Purchase universal circlip pliers for manual installation. This method not only has low installation efficiency and inconvenient manual operation, but also makes workers easily tired after long hours of work. In particular, the expansion range of the circlip pliers is uncontrollable, which can easily cause the retaining ring to deform and affect the assembly quality. Utility Model Content

[0006] The utility model aims to provide a handheld hole-free retaining ring installation device to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a handheld hole-free retaining ring installation device, comprising a support part and a rotating part sleeved outside the support part;

[0008] The rotating part is slidably matched with the guide groove provided on the supporting part through a connecting pin provided thereon;

[0009] The rotation of the rotating part causes the connecting pin to slide along the guide groove, so that the rotating part causes the retaining ring to expand outward along the flaring provided on the supporting part.

[0010] As a preferred technical solution of the utility model: the guide groove is a double helical groove.

[0011] As a preferred technical solution of the utility model: a slot for facilitating the insertion of a retaining ring is provided between the support portion and the flared opening.

[0012] As a preferred technical solution of the utility model: a hand-holding portion is further provided at one end of the support portion away from the flared opening.

[0013] As a preferred technical solution of the utility model: a push plate is further provided on a side of the rotating part facing the flared opening, and the push plate is linked with the rotating part to promote the retaining ring to expand along the flared opening.

[0014] As a preferred technical solution of the utility model: the number of the push plates is multiple and they are arranged in an equidistant array on the rotating part.

[0015] As a preferred technical solution of the utility model: it also includes a positioning member, which is installed in the radial direction of the connecting pin to prevent the connecting pin from separating from the rotating part.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are: 1. Semi-automatic installation of the retaining ring is achieved through a simple mechanism and a small number of parts, which reduces manual force and improves installation quality, thus reducing the cost of the equipment and achieving the installation requirements of the wire retaining ring. Specifically, compared with automated equipment, the equipment has a small number of structures, low use costs and a short design cycle. In particular, it is easy to produce and manufacture, with a short cycle. Therefore, its structure can be modified according to actual needs, which can solve the problem of poor versatility and difficulty in rapid transformation of automated equipment due to a long design cycle;

[0017] 2. Since the retaining ring expands along the flaring, the change in the diameter of the retaining ring during expansion can be controlled by controlling the outer diameter of the flaring, thereby effectively solving the problem of difficulty in controlling the expansion diameter of the retaining ring when using a caliper.

[0021] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0022] See also Figure 1-2 The utility model provides an embodiment: a handheld hole-free retaining ring installation device, comprising a support part 1 and a rotating part 2 sleeved outside the support part 1; the rotating part 2 is slidably matched with a guide groove 3 provided on the support part 1 through a connecting pin 4 provided thereon; through the rotation of the rotating part 2, the connecting pin 4 is caused to slide along the guide groove 3, so that the rotating part 2 causes the retaining ring to expand outward along the flaring 8 provided on the support part 1.

[0023] In summary, the support part 1 is firstly configured to be cylindrical, and the guide groove 3 is opened on its circumferential surface, and then the rotating part 2 is in the shape of a circular tube and is sleeved on the outside of the support part 1; at this time, the connecting pin 4 is passed through the rotating part 2 and connected to the guide groove 3, so that the assembly of the rotating part 2 and the support part 1 can be completed. In addition, the flaring 8 is preferably configured to be trumpet-shaped, so that the retaining ring can be gradually expanded;

[0024] When in use, the rotating part 2 can also rotate the supporting part 1 synchronously at the same time; when rotating, ensure that the rotation directions of the two are completely opposite. For example, if the supporting part 1 rotates clockwise, the rotating part 2 rotates counterclockwise, and the rotating part 2 can be moved on the supporting part 1.

[0025] Based on this, the semi-automatic installation of the retaining ring is realized through a simple mechanism and a small number of parts, which reduces manual force and improves the installation quality, which not only reduces the cost of the equipment, but also meets the installation requirements of the wire retaining ring. Specifically, compared with the automated equipment, the equipment has a small number of structures, low use costs and a short design cycle. In particular, it is easy to produce and manufacture, and the cycle is short. Therefore, its structure can be modified according to actual needs, which can solve the problem of poor versatility and difficulty in rapid transformation of automated equipment due to long design cycles.

[0026] Furthermore, since the retaining ring expands along the flared opening 8, the change in diameter of the retaining ring during expansion can be controlled by controlling the outer diameter of the flared opening 8, thereby effectively solving the problem of difficulty in controlling the expansion diameter of the retaining ring when using a caliper.

[0027] In order to ensure that the rotating part 2 can slide stably and reliably along the supporting part 1, the guide groove 3 is a double helical groove. Therefore, the rotating part 2 can be extended and retracted on the supporting part 1 by rotating the rotating part 2 along the double helical groove; therefore, when the retaining ring is installed on the electric drive shaft, the rotating part 2 is retracted to expose the smallest end of the flared opening 8, so as to facilitate the installation of the new retaining ring on the supporting part 1.

[0028] At the same time, since a slot 7 for inserting a retaining ring is provided between the support portion 1 and the flared opening 8, the retaining ring and the support portion 1 can be assembled smoothly by aligning the opening of the retaining ring with the slot 7 and then pushing the retaining ring into the slot 7.

[0029] Furthermore, since a gripping portion 6 is provided at one end of the support portion 1 away from the flared opening 8, it is convenient for the user to hold the support portion 1 tightly to ensure that the rotating portion 2 and the support portion 1 can rotate smoothly; wherein the gripping portion 6 and the support portion 1 are an integrally formed structure.

[0030] On the basis of the above scheme, in order to ensure that the retaining ring can be smoothly moved along the flared opening 8, a push plate 9 is further provided on the side of the rotating part 2 facing the flared opening 8, and the push plate 9 is linked with the rotating part 2 to cause the retaining ring to expand along the flared opening 8.

[0031] Furthermore, there are multiple push plates 9 , which are arranged in an equidistant array on the rotating part 2 .

[0032] In summary, with the arrangement of the push plate 9, when the rotating part 2 rotates, the push plate 9 is in sheet form, so in the process of causing the retaining ring to slide along the flared opening 8, the push plate 9 can also automatically open to ensure smooth movement of the retaining ring.

[0033] On the basis of the above scheme, it also includes a positioning member 5, which is installed in the radial direction of the connecting pin 4 to prevent the connecting pin 4 from being separated from the rotating part 2. Specifically, the connecting pin 4 is inserted along the radial direction of the rotating part 2 and contacts the guide groove 3, and then the positioning member 5 is inserted into the rotating part 2 from the end face of the rotating part 2; that is, the positioning member 5 is inserted into the rotating part 2 from the side of the rotating part 2 away from the push plate 9, and then pressed against the connecting pin 4, so that the position of the connecting pin 4 after being combined with the rotating part 2 can be stabilized, and the rotating part 2 can be prevented from falling off the rotating part 2 during the rotation process. In addition, the positioning member 5 is preferably a bolt.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
