Description

Technical Field

[0001] This utility model relates to a bearing fixture, and more particularly to a steering knuckle wheel core outer bearing fixture. Background Technology

[0002] When reinstalling a steering knuckle after removing the wheel hub, the outer bearing of the steering knuckle wheel hub needs to be installed first, followed by the shims, and finally the lock nut. However, during the installation of the outer bearing of the steering knuckle wheel hub, the bearing is difficult to fix in position, which makes it easy for the bearing to slip when installing the shims, causing the shims to not be installed properly. This results in uneven gaps between the shims and the bearing, which leads to uneven stress on the bearing during use, causing bearing damage and reducing the service life of the steering knuckle wheel. Utility Model Content

[0003] In view of this, the present invention provides a steering knuckle wheel core outer bearing tooling, including a fastening part for locking the bearing to be installed and a force-applying part for installing a force-applying tool. The shape of the force-applying part matches the shape of commonly used force-applying tools in the workshop. The bearing is placed in the fastening part to constrain the bearing, thereby ensuring accurate installation.

[0004] This utility model also includes a tooling housing, which is integrally formed.

[0005] Furthermore, the fastening part is provided with an internal thread, which increases the friction between the tooling housing and the bearing, preventing the bearing from slipping out. At the same time, the internal thread is relatively easy to process and obtain. The fastening part is provided with a guide angle and a fixing stop. The guide angle facilitates the insertion of the bearing and also prevents the tooling from cutting the operator's fingers when inserting the bearing. The fixing stop can fix the tooling on the operating surface where the bearing needs to be installed.

[0006] Furthermore, the fastening part is equipped with an adjustment mechanism that can accommodate bearings of different sizes. When the largest bearing that the fastening part can accommodate is placed, no additional operation is required; while when a slightly smaller bearing is placed, the bearing is fastened by the adjustment mechanism to assist in the installation.

[0007] Furthermore, the adjustment mechanism includes an adjustment handle that moves along the circumference of the tooling and a clamping block that can be automatically retracted. Moving the adjustment handle causes the clamping block to extend and perform a tightening action.

[0008] Furthermore, an inclined structure is formed between the adjusting handle and the clamping block, which converts the circumferential movement of the adjusting handle into the radial movement of the clamping block; this inclined surface is a force-saving inclined surface, and the force exerted by the operator's sliding will be amplified by the inclined surface, thereby strengthening the fastening effect.

[0009] Furthermore, a spring is provided between the clamping block and the tooling housing. When the clamping block is not under force, the clamping block automatically retracts. Since the adjustment handle and the clamping block are inclined structures that save effort for the operator, this structure is an inclined structure that requires more effort from the spring that applies force in the opposite direction. Therefore, the spring needs a certain spring coefficient to ensure that the spring can restore the adjustment mechanism by its own elasticity.

[0010] Since the reverse force application of this inclined structure is a force-consuming mechanism, when the bearing is tightened by moving the adjustment handle, the reaction force of the bearing is reduced, which reduces the force required for the operator to maintain the tightening and lightens the operator's burden.

[0011] The beneficial effects of this utility model are as follows: the use of a steering knuckle wheel core outer bearing tooling with a force-applying fastening part improves the efficiency and accuracy of bearing installation, avoids improper installation of shims due to inconsistent bearing positions, and extends the service life of the steering knuckle wheel; at the same time, it is also equipped with an adjustment mechanism to adapt to bearings of different sizes, which can improve the versatility of the tooling. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0013] Figure 1 This is a top view of the present invention;

[0014] Figure 2 yes Figure 1 AA section diagram;

[0015] Figure 3 yes Figure 2 BB cross-sectional view. Detailed Implementation

[0016] This utility model provides a steering knuckle wheel core outer bearing tooling, including a fastening part 1 for locking the bearing to be installed and a force-applying part 2 for installing a force-applying tool. The shape of the force-applying part 2 matches the shape of commonly used force-applying tools in the workshop. The bearing is placed into the fastening part 1 to constrain the bearing, thereby ensuring accurate installation.

[0017] This utility model also includes a tooling housing 5, which is integrally formed from cast iron material, and the outer surface of the tooling housing 5 is treated with rust prevention.

[0018] In this embodiment, the fastening part 1 is provided with an internal thread. The internal thread increases the friction between the tooling housing and the bearing, preventing the bearing from slipping out. At the same time, the internal thread is relatively simple to process and easy to obtain. Other patterns that increase friction can also be used, or a friction pad can be covered on the inner ring of the fastening part, as long as it can strengthen the friction between the tooling and the bearing. The fastening part 1 is provided with a guide angle 4 and a fixing stop 3. The guide angle 4 facilitates the insertion of the bearing and also avoids the tooling from cutting the operator's fingers when inserting the bearing. Here, it is set as a C1 chamfer. The fixing stop 3 can fix the tooling on the operating surface where the bearing needs to be installed. At the same time, the guide angle 4 should not be too large. If the guide angle is too large, it will reduce the cross-sectional area of ​​the fixing stop, thus making the tooling unreliable.

[0019] At the same time, the fastening part opens inward, or towards the force-applying part, to connect the fastening part 1 and the force-applying part 2, so as to facilitate observation of the bearing's fixing status and to facilitate removal when the bearing is stuck in the fastening part.

[0020] In this embodiment, the fastening part is provided with an adjustment mechanism 6 that can adapt to bearings of different sizes. When the largest bearing that the fastening part 1 can accommodate is placed, no additional operation is required, and it is fastened by the structural constraints and friction within the fastening part. However, when a slightly smaller bearing is placed, or due to wear inside the fasteners after long-term use, it is necessary to use the adjustment mechanism to fasten the bearing to assist in the installation.

[0021] In this embodiment, the adjustment mechanism 6 includes an adjustment handle 601 that slides circumferentially along the outer surface of the tooling and a clamping block 602 that can be automatically retracted. When the adjustment handle 601 is moved, the clamping block 602 extends to perform a fastening action; and a sliding groove that can accommodate the sliding of the adjustment handle is machined on the outer surface of the tooling.

[0022] When using the tool, apply lubricating oil between the adjusting handle and the tool housing to reduce wear and extend the tool's service life.

[0023] In this embodiment, an inclined structure is formed between the adjusting handle and the clamping block, which converts the circumferential movement of the adjusting handle into the radial movement of the clamping block. This inclined surface is a force-saving inclined surface, and the force exerted by the operator's sliding will be amplified by the inclined surface, thereby strengthening the fastening effect. The mechanical analysis here can be easily analyzed by those skilled in the art based on the inclined cross-sectional schematic diagram in Figure 3, and will not be elaborated here.

[0024] In this embodiment, a spring 6021 is provided between the clamping block and the tooling housing. When the clamping block 602 is not under force, the clamping block automatically retracts. Since the adjustment handle and the clamping block are inclined structures that save effort for the operator, this structure is an inclined structure that requires more effort from the spring that applies force in the opposite direction. Therefore, the spring needs a certain spring coefficient to ensure that the spring can restore the adjustment mechanism by its own elasticity.

[0025] Since the reverse force application of this inclined structure is a force-consuming mechanism, when the bearing is tightened by moving the adjustment handle, the reaction force of the bearing is reduced, which reduces the force required for the operator to maintain the tightening and lightens the operator's burden.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
