Description

Technical Field

[0001] This utility model relates to the field of ABS gear ring press-fitting technology, and in particular to an ABS gear ring press-fitting tool. Background Technology

[0002] As a key sensing component of the automotive anti-lock braking system (ABS), the press-fit quality of the ABS gear ring directly affects driving safety. During the press-fit process, achieving rapid and accurate positioning of the gear ring is crucial to ensuring that key dimensions such as end face runout and positional accuracy meet process requirements. Currently, the widely used ABS gear ring press-fitting fixtures in the industry primarily employ fixed positioning sleeves or rigid positioning pins for their positioning structure. Specifically, this type of fixture processes a fixed inner hole or outer circle that matches the theoretical dimensions of the target gear ring as a positioning reference. During operation, the gear ring is placed within this fixed reference before press-fitting. Each different model and size of ABS gear ring requires a dedicated press-fitting fixture.

[0003] Because existing ABS gear ring pressing fixtures are only applicable to gear rings of a single size, when repairing vehicles and installing ABS gear rings of different sizes, workers need to change the corresponding pressing fixtures back and forth. This not only increases the management and manufacturing costs of the fixtures, but also reduces the efficiency of ABS gear ring installation. Utility Model Content

[0004] Therefore, it is necessary to provide an ABS gear ring press-fitting tool to address the problem that existing ABS gear ring press-fitting fixtures can only be used for gear rings of a single size, which requires changing the corresponding press-fitting fixtures when installing ABS gear rings of different sizes, increasing the management and manufacturing costs of the fixtures and reducing the installation efficiency of ABS gear rings.

[0005] An ABS gear ring pressing fixture includes: an installation mechanism, the installation mechanism including an upper mounting cover, a lower mounting cover and an operating rod, the upper mounting cover being bolted to the upper surface of the lower mounting cover, and the operating rod being disposed on the upper surface of the upper mounting cover; The clamping mechanism is provided in several groups, and each group of clamping mechanisms includes a magnetic ring, a clamping block, a compression spring, and an adjustment component for adjusting the extension length of the magnetic ring. The magnetic ring is slidably disposed on the lower surface of the upper mounting cover. The magnetic ring is located on the upper surface of the toothed ring. The compression spring is fixedly disposed on the side of the clamping block away from the toothed ring, and the clamping block is engaged with the inner side of the teeth on the outer arc surface of the toothed ring.

[0006] In one embodiment, snap-fit ​​blocks are fixedly provided on both sides of the clamping block, and the snap-fit ​​blocks are configured as convex blocks. The clamping block, compression spring and snap-fit ​​blocks are all disposed inside the lower mounting cover.

[0007] In one embodiment, the lower mounting cover has a clamping groove corresponding to the clamping block and the compression spring inside, and a snap-fit ​​groove corresponding to the snap-fit ​​block inside, and the clamping groove and the corresponding snap-fit ​​groove are connected.

[0008] In one embodiment, the adjustment assembly includes an extension post, a limiting ball, and a connecting post, wherein the connecting post is fixedly disposed on the upper surface of the magnetic ring, and the limiting ball is disposed between the extension post and the connecting post.

[0009] In one embodiment, a spring plunger is fixedly provided on the outer arc surface of the extension column, and an extension groove corresponding to the extension column and the spring plunger is opened inside the upper mounting cover. A number of positioning holes corresponding to the spring plunger are opened on the inner side of the extension groove.

[0010] In one embodiment, a pull ring is fixedly provided at the top of the extension column, and the diameter of the limiting ball is larger than the diameter of the extension column and the connecting column.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-6 This invention describes the ABS gear ring press-fitting fixture.

[0020] In one embodiment, an ABS gear ring press-fitting fixture includes: a mounting mechanism 100, which includes an upper mounting cover 101, a lower mounting cover 102, and an operating rod 103. The upper mounting cover 101 is bolted to the upper surface of the lower mounting cover 102, and the operating rod 103 is disposed on the upper surface of the upper mounting cover 101; and a clamping mechanism 200, which is provided in several groups. Each group of clamping mechanisms 200 includes a magnetic ring 201, a clamping block 203, a compression spring 204, and an adjustment component for adjusting the extension length of the magnetic ring 201. The upper surface of the lower mounting cover 102 is provided with a sliding groove 202 corresponding to the magnetic ring 201, and the magnetic ring 201 does not contact the clamping block 203. In this embodiment, the upper mounting cover 101 and the lower mounting cover 102 are bolted together to form a closed housing that houses the clamping mechanism 200. The operating lever 103 is used to connect to external pressing equipment or is convenient for workers to hold directly, transmitting pressing force through machine or manual hammering. A sliding groove 202 is provided to ensure that the magnetic ring 201 can extend to different lengths. When the magnetic ring 201 extends to fit a toothed ring of a certain size, it will be slightly shorter than the toothed ring, thus ensuring adsorption of the toothed ring while preventing the magnetic ring 201 from rubbing against the mounting shaft after installation. The magnetic ring 201 and the clamping block 203 are spatially independent, respectively responsible for adsorption and fixation on the upper surface of the toothed ring and radial clamping on the outer circumference. They work together but do not interfere with each other.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the magnetic ring 201 is slidably disposed on the lower surface of the upper mounting cover 101. The magnetic ring 201 is located on the upper surface of the gear ring. The compression spring 204 is fixedly disposed on the side of the clamping block 203 away from the gear ring, and the clamping block 203 is engaged with the inner side of the teeth on the outer arc surface of the gear ring. The clamping block 205 is fixedly disposed on both sides of the clamping block 203. The clamping block 205 is configured as a convex block. The clamping block 203, the compression spring 204 and the clamping block 205 are all disposed inside the lower mounting cover 102. The lower mounting cover 102 has a clamping groove 206 corresponding to the clamping block 203 and the compression spring 204, and a clamping groove 207 corresponding to the clamping block 205. The clamping groove 206 and the corresponding clamping groove 207 are connected. In this embodiment, under the preload of the compression spring 204, the front end of the clamping block 203 tends to move centripetally. When the gear ring is placed in the central area of ​​the lower mounting cover 102, the outer circumference of the gear ring will press against the inclined front end of each clamping block 203, forcing the clamping block 203 to move outward against the spring force. As the gear ring continues to fall, the clamping block 203 will smoothly engage with the gap between any two adjacent teeth on the outer arc surface of the gear ring under the action of the spring force. During engagement, the clamping mechanism 200 as a whole can rotate, thereby achieving radial automatic centering and clamping. The convex fit between the engaging block 205 and the engaging groove 207 effectively prevents the clamping block 203 from coming out of the clamping groove 206 under pressure, ensuring the reliability of the clamping process. This allows the same tooling to adapt to gear rings with different pitch circle diameters within a certain size range, achieving versatility.

[0022] like Figure 5 and Figure 6 As shown, the adjustment assembly includes an extension post 208, a limiting ball 210, and a connecting post 211. The connecting post 211 is fixedly mounted on the upper surface of the magnetic ring 201, and the limiting ball 210 is positioned between the extension post 208 and the connecting post 211. A spring plunger 209 is fixedly mounted on the outer arc surface of the extension post 208. An extension groove 214 corresponding to the extension post 208 and the spring plunger 209 is opened inside the upper mounting cover 101. Several sets of positioning holes 215 corresponding to the spring plunger 209 are opened inside the extension groove 214. A pull ring is fixedly mounted on the top of the extension post 208. The diameter of the limiting ball 210 is larger than the diameter of the extension post 208 and the connecting post 211. A connecting groove 212 corresponding to the connecting post 211 is opened inside the upper mounting cover 101. A limiting groove 213 corresponding to the limiting ball 210 is opened inside the upper mounting cover 101. The connecting groove 212 and the corresponding limiting groove 213 are connected. In this embodiment, the adjustment component is used to accommodate gear rings of different diameters. When it is necessary to adjust the extension length of the magnetic ring 201, the operator pulls the pull ring upwards, causing the extension post 208 to slide within the extension groove 214. At this time, the spring plunger 209 is compressed, and the post of the spring plunger 209 moves along the extension groove 214. When it disengages from the current positioning hole 215, the extension post 208 moves. The limiting ball 210 is constrained within the limiting groove 213, and its diameter is larger than that of the connecting post 211, thereby preventing the entire component from falling off due to gravity or vibration. After the magnetic ring 201 is adjusted to the appropriate position, the pull ring is released, and the spring plunger 209, under its own elastic force, engages in the positioning hole 215 corresponding to the gear ring of that specification, achieving position locking. This allows the lower surface of the magnetic ring 201 to stably adhere to the upper surface of the gear ring, providing axial fixing force.

[0023] Working Principle: First, based on the diameter of the ABS gear ring to be pressed, the extension posts 208 are pulled and adjusted to ensure that the extended length of all magnetic rings 201 is adapted to the gear ring of that specification, and this extended length is slightly shorter than the expected position on the upper surface of the gear ring, ensuring that the magnetic rings 201 can effectively attract the gear ring. After adjustment, the spring plunger 209 is locked into the corresponding positioning hole 215. The gear ring is placed in the center area of ​​the lower mounting cover 102. During the descent of the gear ring, its outer circumference will press against the circumferentially distributed clamping blocks 203. Under the action of the compression spring 204, the clamping blocks 203 automatically find and engage with the gap between the teeth of the gear ring, completing the radial automatic centering and initial clamping of the gear ring. After the gear ring is radially positioned, its upper surface contacts the magnetic rings 201 that have been adjusted to the correct height. The magnetic force generated by the magnetic rings 201 firmly attracts the upper surface of the gear ring, providing axial constraint and preventing the gear ring from tilting or falling off during movement or pressing. The external pressing equipment applies downward pressure to the entire fixture via the operating lever 103. The fixture, carrying the gear ring which has been stably clamped and attracted, moves precisely to the target installation position and presses the gear ring into place. After pressing, the fixture moves upward, at which point the gear is locked in place at the installation position, and the fixture can then be completely separated from the gear ring.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
