Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and in particular relates to a tooling fixture for press-fitting a ball head gasket. Background Art

[0002] like Figure 5 The figure shows the ball head part of a common ball stud, which is mainly composed of a ball stud rod and a ball head. There is a limiting step on the ball stud rod, which is used to limit the axial position of the ball stud rod when it is installed and fixed with other components. However, in the actual processing and manufacturing process, affected by the manufacturing process and cost constraints, the diameter of the limiting step on the ball stud rod is usually only about 4-5mm larger than the diameter of the external thread on the ball stud rod. This means that when the ball head is installed and fixed with other components, during the process of tightening the locking nut, the initial tightening torque is too small and cannot be tightened to the fixed torque, resulting in poor stability in the installation and fixation of the ball head.

[0003] In order to solve this problem, a gasket is usually pressed on the limit step of the ball head rod. For example, Chinese patent application number (CN201920090279.5) discloses an anti-rotation ball pin assembly, which solves the above problem by pressing a hobbing gasket on the limit step of the ball head rod.

[0004] However, due to the influence of the structure of the ball head, how to fix the ball head when the gasket is pressed into the ball head rod has an important impact on the quality of the gasket press-fitting. However, the current tooling fixtures have low efficiency and precision in clamping the ball head, which needs to be improved. Utility Model Content

[0046] A fastening assembly 5 is mounted on the bracket 1 and is used to fix and release the ball head 10 on the base 2;

[0047] Wherein, the ball head 10 is arranged vertically;

[0048] Among them, the ball head 10 structure applicable to this application is Figure 5 As shown, from top to bottom, the ball head 10 includes a screw portion 100, a limiting step 101, a neck portion 102, and a ball head portion 103, and the neck portion 102 is adapted to the slot 4. In order to adapt to different ball head 10 structures, the slot 4 in the base 2 of the present application can adopt different structures to adapt to the neck portions 102 of different models of ball heads 10.

[0049] It can be seen from this embodiment that by adopting the card slot 4 provided on the base 2, it is convenient to card the ball head 10 into the card slot 4, the operation is simple and quick, and the ball head 10 is pre-fixed by the limiting step 101 on the ball head 10, and then the ball head 10 is fixed by the fastening assembly 5, the structure has good stability and high precision, and it is convenient to press the gasket 11 on the ball head 10 rod of the ball head 10;

[0050] The vertically arranged ball head 10 facilitates the press-fitting of the gasket 11 .

[0051] Embodiment 2:

[0052] This embodiment provides a fixture for pressing a ball head gasket. In addition to the technical solutions of the above embodiments, it also has the following technical features. The fastening assembly 5 includes:

[0053] The fixed module 50 is mounted on the base 2 and has a first cavity 51 adapted to the ball head 10;

[0054] The moving module 52 is slidably connected to the bracket 1 and is provided with a second cavity 53 adapted to the ball head 10;

[0055] A driving member 54 is mounted on the bracket 1 and is used to drive the moving module 52 to slide on the bracket 1;

[0056] The fixed module 50 is installed in the base 2 and is fixed to the base 2 by bolts.

[0057] It can be seen from the present embodiment that by adopting the fixed module 50 and the movable module 52, on the one hand, it is convenient to fix and release the ball head 10, and on the other hand, the first cavity 51 and the second cavity 53 play a role in limiting and adjusting the position of the ball head 10, thereby improving the installation accuracy of the ball head 10 and the press-fitting accuracy of the gasket 11.

[0058] Embodiment 3:

[0059] This embodiment provides a fixture for pressing a ball head gasket. In addition to the technical solutions of the above embodiments, it also has the following technical features. The driving member 54 includes:

[0060] The support plate 540 is slidably connected to the bracket 1 by means of a slider 541 and a slide rail 542, and the moving module 52 is mounted on the support plate 540;

[0061] The screw assembly 543 is mounted on the bracket 1, and the output end is connected to the support plate 540;

[0062] A driving motor 544 is mounted on the bracket 1 and is used to drive the screw assembly 543;

[0063] Among them, the specific structure of the screw assembly 543 and the driving motor 544 is an existing mature technology and will not be repeated here.

[0064] It can be seen from this embodiment that the screw assembly 543 is driven by the driving motor 544, thereby pushing the moving module 52 to move toward the fixed module 50, and cooperates with the fixed module 50 to fix the ball head 10, which has a simple structure and is easy to drive;

[0065] Furthermore, the slide block 541 and the slide rail 542 can improve the stability of the moving module 52 during movement, ensure the matching accuracy with the fixed module 50 , and further ensure the accuracy of the fixed position of the ball head 10 .

[0068] The top ends of the first cavity 51 and the second cavity 53 both extend toward one side of the ball head 10 to form a pressing portion 55;

[0069] When the fixed module 50 and the movable module 52 fix the ball head 10, a gap is left between the two.

[0070] At the same time, the downward pressure part 55 and the fixed module 50 and the movable module 52 all adopt an integrated structure, and the specific structure of the downward pressure part 55 is shown in the drawings. When the movable module 52 and the fixed module 50 are close to each other, the downward pressure part 55 will exert a downward force on the ball head 103 of the ball head 10.

[0071] It can be seen from the present embodiment that by arranging the pressing portion 55 in both the first cavity 51 and the second cavity 53, a gap is left between the fixed module 50 and the movable module 52 when the ball head 10 is fixed. This enables a downward pulling force to be exerted on the ball head 10 when the ball head 10 is fixed by the movable module 52, thereby improving the structural stability and accuracy of the fixation of the ball head 10, and further improving the press-fitting accuracy of the gasket 11.

[0084] A support member 9 for supporting is provided below the bracket 1, and the card slot 4 is provided on the opposite side of the two bases 2;

[0085] At the same time, the indexer 8 is used to drive the bracket 1 to reciprocate by 180 degrees. Its specific structure is an existing mature technology and will not be described here.

[0086] It can be seen from this embodiment that by providing two bases 2 and relatively arranging them on the bracket 1, the two bases 2 are respectively used for the press-fitting station and the loading station, which effectively improves the processing efficiency, and the bracket 1 is reciprocated by 180° by the indexer 8, so as to facilitate the switching and adjustment of the press-fitting station and the loading station, thereby improving convenience;

[0087] The slot 4 is provided on the opposite side of the two bases 2 to prevent the ball head 10 in the slot 4 from sliding out of the slot 4 due to centrifugal force when the bracket 1 is rotated, thereby improving the stability of the pre-fixation of the ball head 10 in the slot 4.

[0088] The support member 9 can improve the support strength of the bracket 1 when the ball head 10 and the gasket 11 are press-fitted, thereby extending the service life of each structure.
