Description

Assembly device for circlips

technical field

The utility model relates to the technical field of mechanical assembly devices, in particular to an assembly device for snap springs.

Background technique

Engine assembly is generally mass-produced, requiring high production efficiency. A large number of circlips are used in the engine. The circlip for the shaft is a kind of axial movement installed on the grooved shaft for fixing parts. The inner diameter of this type of retaining ring is slightly smaller than the diameter of the assembly shaft. Usually, the lifting ears at both ends of the circlip are stretched by the pointed mouth of the circlip pliers, and then put on the shaft to complete its installation. The small shaft circlip is rather special, and there is no lifting lug for the circlip pliers on it. The ordinary circlip pliers cannot be used, and the installation is very inconvenient. Moreover, the position of the circlip is prone to shift when the circlip pliers are used for assembly. , poor accuracy, low worker efficiency, high labor intensity, high risk, and cannot meet the requirements of mass production.

Utility model content

The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an assembly device for the clip spring, which can make the clip spring assembled accurately in place, save time and effort, and have high production efficiency.

The technical solution adopted by the utility model to solve the problems of the prior art: an assembly device for the circlip, including an expansion sleeve, a telescopic sleeve and a cylinder body, the left end of the expansion sleeve is provided with a positioning recess for fixing the workpiece to be processed groove, the right end of the expansion sleeve is provided with an opening for accommodating the circlip, the diameter of the left end of the expansion sleeve is larger than the diameter of the right end of the expansion sleeve, the end of the telescopic sleeve abuts against the right end of the expansion sleeve, and the cylinder A piston rod connected with the telescopic sleeve is arranged inside.

Further, the telescopic sleeve is provided with an elastic element connected to the head of the piston rod.

Further, the elastic element is a return spring.

Further, a bracket is provided on the cylinder body, and the bracket is fixed on the workbench by bracket bolts.

Further, the telescopic sleeve is connected to the piston rod through threads.

Adopting the above-mentioned technical scheme, the utility model has the following beneficial effects:

The utility model can make the circlip assembly in place accurately, saves time and effort, and has high production efficiency, and can be widely used in machinery manufacturers and maintenance enterprises.

Detailed ways

In order to make the content of the utility model more clearly understood, the utility model will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

As shown in FIGS. 1 to 4 , an assembly device for a circlip includes an expansion sleeve 1 , a telescopic sleeve 2 and a cylinder body 6 . The expansion sleeve 2 is used to fix the relative position of the workpiece 8 to be processed and the circlip 9 , and provide guidance for the circlip 9 ; the telescopic sleeve 2 is used to push the circlip 9 into the workpiece 8 to be processed.

As shown in Figure 1, Figure 3 and Figure 4, the left end of the expansion sleeve 1 is provided with a positioning groove for fixing the workpiece 8 to be processed, and the right end of the expansion sleeve 1 is provided with an opening for accommodating a circlip 9. The diameter of the left end of the expansion sleeve 1 is greater than the diameter of the right end of the expansion sleeve 2, and the end of the expansion sleeve 2 abuts against the right end of the expansion sleeve 1, and the piston rod 4 connected with the expansion sleeve 2 is arranged in the cylinder body 6 . The telescopic sleeve 2 is provided with an elastic element 3 connected to the head of the piston rod 4 . The telescopic sleeve 2 is threadedly connected with the piston rod 4, and the piston rod 4 is driven by the cylinder in the cylinder body 6 to reciprocate.

As shown in FIG. 1 , a bracket 5 is provided on the cylinder body 6 , and the bracket 5 is fixed on the workbench by bracket bolts 7 .

In this embodiment, the elastic element 3 is a return spring, but the type of the elastic element 3 is not limited.

The working principle of the utility model is as follows:

When assembling the circlip 9, insert the opening size a of the circlip 9 along the opening of the expansion sleeve 1, insert the small shaft end of the workpiece 8 into the positioning groove of the expansion sleeve 1, press the cylinder, Make the piston rod 4 move to the left, the piston rod 4 is connected with the telescopic sleeve 2 and moves to the left along the expansion sleeve 1 (at this time, the expansion sleeve 1 does not move), and the end of the telescopic sleeve 2 pushes against the circlip 9 and moves along the expansion sleeve 1 The cone of 1 moves to the left, and the diameter of the circlip 9 gradually expands until it is introduced into the circlip groove of the workpiece 8, the piston rod 4 returns to its original position, and the workpiece 8 with the circlip 9 installed is removed.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present utility model in detail. It should be understood that the above descriptions are only specific embodiments of the present utility model and are not intended to limit the present invention. For the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
