DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0023] According to Figures 1 to 5 As shown: This embodiment provides a quick press-fitting mold for a circlip, including a mold body 400, a linear driving assembly, and a corresponding tooling platform. Among them, the mold body 400 and the linear driving assembly are wound on the above tooling platform, and a series of actions are completed through system control to place the circlip 300 into the pulley 700. The specific implementation structures of each component are as described below.

[0024] The mold body 400 includes a guiding member 200 and a braking member 100. Both the guiding member 200 and the braking member 100 are made of metal material, wherein:

[0025] An annularly distributed mounting table 203 is further provided on the outer wall of the guiding member 200. The guiding member 200 is vertically distributed and is positioned and installed on the tooling platform through the mounting table 203. A vertically penetrating channel 201 is provided in the middle of the guiding member 200. The lower end of the channel 201 has a guiding section 202 with a diameter gradually shrinking from inside to outside, so that the surface of the guiding section 202 is an inclined plane. During use, the channel 201 is mainly used to accommodate the placement of the snap ring 300 and the movement of the braking member 100. When the snap ring 300 passes through the guiding section 202, the diameter of the placement space of the snap ring 300 in the guiding section 202 gradually decreases, so that the snap ring 300 shrinks to a size that can enter the pulley 700;

[0026] The braking member 100 adopts a tubular structure. The braking member 100 includes a pressing head 101 with an elastically shrinkable diameter. The pressing head 101 is located at the lower part of the braking member 100. Among them, in order to realize the elastic shrinkage change of the pressing head 101, ten groups of radially uniformly distributed gaps 102 are provided on the pressing head 101. The size of the gaps 102 needs to meet the requirement that the pressing head 101 shrinks to the set minimum diameter. The gaps 102 extend towards the middle of the body of the guiding member 200. The longer the length of the gaps 102, the longer the swingable structural part of the pressing head 101, so that the flexible elastic shrinkage change of the pressing head 101 can be satisfied, and thus the pressing head 101 has an ideal use effect;

[0027] The pressing head 101 is located in the channel 201 of the guiding member 200 and presses the snap ring 300 out from the opening at the end of the channel 201 towards the inside of the channel 201. The diameter of the pressing head 101 is equal to the minimum diameter of the channel 201, so that the pressing head 101 can move at any position in the guiding member 200, thus meeting the use effect of pressing the snap ring 300 out of the guiding member 200.

[0028] The tooling platform includes a platform body 600, a sliding table 800, a mold body 400 and three sets of linear driving components. The linear driving components all adopt cylinders. The specific implementation structure is as follows:

[0029] The front part of the platform body 600 has an operation space. The pulley 700 can be placed on the bottom surface of the operation space through a positioning component that matches the shape of its edge. The sliding table 800 is slidably assembled on the side surface at the rear of the operation space through a guide rail component. A functional block is installed on the front side of the sliding table 800. The functional block is formed by processing a metal block. The functional block includes a horizontal channel for the lateral movement of the snap ring 300. A through hole is vertically distributed at the left end of the horizontal channel. The mold body 400 is installed at the lower part of the through hole. The guide member 200 is positioned and assembled with the platform body 600 through its mounting table 203 to form an integral body, while the braking member 100 is vertically movably assembled on the upper part of the guide member 200. A material rod is installed at the right end of the horizontal channel, and several snap rings 300 are sleeved outside the material rod;

[0030] The three sets of linear drive components include:

[0031] The first linear drive component 501 is vertically installed on the sliding table 800. The first linear drive component 501 is located above the braking member 100. The first linear drive component 501 is connected to the braking member 100 and drives the braking member 100 to enter or leave the guide member 200. Through this action, the snap ring 300 can be pushed downward until the snap ring 300 leaves the guide member 200 and enters the pulley 700;

[0032] The second linear drive component 502 is horizontally installed on the sliding table 800. The second linear drive component 502 is located on one side of the functional block and is connected to a push piece located in the horizontal channel. The second linear drive component 502 drives the push piece to move horizontally to push the snap ring 300 at the position of the material rod into the left guide member 200;

[0033] The third linear drive component 503 is vertically installed on the platform body 600. The third linear drive component 503 is located above the sliding table 800 and is connected to the sliding table 800 to drive the sliding table 800 to slide vertically. When the sliding table 800 leaves the working position and moves upward, it can meet the needs of replacing the pulley 700 and the operation space.

[0034] The above is only the preferred implementation mode of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means are within the protection scope of the present invention.
