Description

Technical Field

[0001] The utility model relates to the technical field of retaining ring pressing tooling, in particular to a flattened steel wire retaining ring pressing tooling. Background Art

[0002] Retaining rings: These are closed or open rings fastened to a shaft to secure other components mounted on the shaft in either the axial or circumferential direction. Currently, standard retaining rings typically have two small holes, which facilitate the installation of circlip pliers. However, for some precision products, internal retaining rings made with standard internal holes do not meet the required dimensions, so custom retaining rings without small holes and with a uniform appearance are often used.

[0003] A patent search revealed that the retaining ring pressing tool with publication number CN219521157U has a workpiece inserted into the installation channel, the retaining ring is placed flatly from the slide, and the pressure head is inserted from the slide and pressed down. The retaining ring gradually shrinks during the pressing process until it is pressed into the inner hole to be installed, thereby achieving quick and convenient installation of customized inner hole retaining rings with uniform appearance without small holes, greatly improving the installation efficiency of the retaining ring. When placing the retaining ring in the above-mentioned comparative document, since the diameter of the retaining ring is smaller than the slide, the retaining ring is prone to falling directly and tilting during placement, which makes it impossible to press-fit the retaining ring subsequently.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The top screw part 7 is screwed into the bottom of the screw hole, and a top pressure plate 6 is fixed at the bottom of the top screw part 7. The top pressure plate 6 is placed horizontally below the bottom pressure plate 5, and a pressure head with the same function as the reference document is installed at the bottom of the top pressure plate 6. At the same time, the structure of the pressing sleeve 9 is the same as that of the reference document. The pressure head is placed in the cavity of the pressing sleeve 9, which can push the retaining ring downward so that the workpiece is placed at the bottom of the pressing sleeve 9, and the retaining ring can be pressed onto the workpiece.

[0025] The horizontal plate opening portion 10 is opened at the top port of the pressed-in sleeve 9, and a supporting horizontal plate 11 slides horizontally in the groove of the horizontal plate opening portion 10, and the groove of the horizontal plate opening portion 10 is connected to the displacement slot 12 below, and the displacement slot 12 and the trigger plate 13 are distributed in a ring array and arranged in multiple groups. The trigger plate 13 is obliquely penetrated in the groove of the displacement slot 12, and the two ends of the trigger plate 13 are connected to the groove side wall of the displacement slot 12 through a rotating shaft. The trigger plate 13 can be rotated in the groove of the displacement slot 12 through the rotating shaft. The bottom of the displacement slot 12 is connected to the spring portion 14 through the vertical plate, and the front end of the spring portion 14 is connected to the surface of the trigger plate 13. The bottom part of the trigger plate 13 adopts a plate-like structure. Since the trigger plate 13 is tilted as a whole, the The plate-shaped upper portion is also inclined relative to the downward pressing connecting rod 15. When the downward pressing connecting rod 15 descends, the front end of the downward pressing connecting rod 15 moves downward from the inclined surface of the trigger plate 13, thereby applying pressure to the trigger plate 13. When the trigger plate 13 is pressed, the trigger plate 13 rotates due to the action of the rotating shaft. The upper half of the trigger plate 13 adopts a retractable two-stage structure. The top of the trigger plate 13 is connected to the bottom of the supporting cross plate 11 via the rotating shaft. As the trigger plate 13 rotates, it pushes the supporting cross plate 11, withdrawing the supporting cross plate 11 originally concentrated at the top center of the press sleeve 9, allowing the retaining ring to fall horizontally, facilitating the horizontal descent of the press head and its contact with the retaining ring, improving the stability of the retaining ring-press head connection, and thus improving the processing quality of the entire press tool. The top of the downward pressing connecting rod 15 is fixed to the bottom of the top pressure plate 6. After the top pressure plate 6 is combined with the bottom pressure plate 5, the downward pressing connecting rod 15 is positioned just above the trigger plate 13. A sleeve support 8 is fixed to the bottom of the press-in sleeve 9, so that the sleeve support 8 is L-shaped, and the lower position of the press-in sleeve 9 is staggered. A workpiece support plate 16 is installed at the lower position of the press-in sleeve 9, wherein the top of the workpiece support plate 16 is used to place the workpiece to be pressed into the retaining ring. At the same time, an operating handle plate 17 is fixed to the side wall of the workpiece support plate 16, and a longitudinal slide plate 18 is fixed to the top of the tooling base plate 1, wherein the operating handle plate 17 can slide longitudinally along the longitudinal slide plate 18. Therefore, after the workpiece is placed on the workpiece support plate 16, the workpiece can be placed in the press-in sleeve 9 cavity by lifting the operating handle plate 17, and then the subsequent retaining ring pressing process is carried out.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
