Description

Technical Field

[0001] The utility model relates to the field of automobile positioning tooling equipment, in particular to a rear auxiliary frame bushing press-fitting mechanism. Background Art

[0002] The rear subframe of the vehicle is used to connect the body and the suspension. In modern automobile production, bushings are set on the mounting points of the rear subframe and the body (i.e., the sleeves at the four corners) to improve ride comfort. The existing method is to place the bushing on the sleeve and then use a pressure head to squeeze the bushing into the sleeve. However, during the squeezing process, the pressure head is prone to tilting the bushing due to uneven force, resulting in a gap between the upper edge of the bushing and the upper edge of the sleeve, resulting in a loose fit between the bushing and the sleeve, affecting ride comfort. Utility Model Content

[0003] The utility model provides a rear auxiliary frame bushing pressing mechanism which has a simple structure and can always keep the bushing pressed vertically to avoid a gap between the bushing and the sleeve.

[0004] The rear subframe bushing pressing mechanism described in the utility model includes a base connected to a pressing device, a pressing head abutting against the bushing is provided at the bottom of the base, a movable mechanism is also provided between the base and the pressing head, the movable mechanism includes a hemispherical block and a support cover, the support cover is provided with a hemispherical groove that cooperates with the arc surface of the hemispherical block and can slide relatively, the support cover is sleeved on the arc surface of the hemispherical block, a connecting column extending upward and passing through the hemispherical block and the support cover is provided in the middle of the pressing head, and a connecting plate connected to the connecting column is installed above the support cover in the base.

[0005] The rear subframe bushing pressing mechanism comprises a hemispherical block and a support cover installed between the pressing head and the base. The support cover is sleeved on the arc surface of the hemispherical block and can slide relatively. In the process of pressing the bushing into the rear subframe sleeve, the hemispherical block can slide relative to the support cover according to the inclination angle of the bushing to distribute the pressure on the bushing, so that the upper surface of the bushing remains level with the horizontal plane, thereby achieving the bushing being pressed vertically downward into the rear subframe sleeve, avoiding gaps between the bushings and improving production efficiency.

[0011] like Figure 1-5 As shown, a rear subframe bushing press-fitting mechanism includes a base 2 connected to a pressing device 1, a pressing head 4 abutting against a bushing 3 is provided at the bottom of the base, and a movable mechanism is provided between the base and the pressing head, and the movable mechanism includes a hemispherical block 5 and a support cover 6, the support cover is provided with a hemispherical groove 601 that matches the arc surface of the hemispherical block and can slide relatively, the support cover is sleeved on the arc surface of the hemispherical block, a connecting column 401 extending upward through the hemispherical block and the support cover is provided in the middle of the pressing head 4, and a connecting plate 7 connected to the connecting column is installed above the support cover in the base. Figure 1 As shown, the pressing device 1 is movably installed above the rear sub-frame bushing through a frame and a moving mechanism that can move forward, backward, left and right, and can move up and down through the coordinated installation of a guide rod and a motor. The moving mechanism, the guide rod and the motor's coordinated installation mechanism are all conventional structures that can achieve forward, backward, left and right, and up and down movement. The rear sub-frame bushing pressing mechanism described above is through a hemispherical block and a support cover installed between the pressure head and the base. The support cover is relatively slidable on the arc surface of the hemispherical block. In the process of pressing the bushing into the rear sub-frame sleeve, the hemispherical block can slide relative to the support cover according to the inclination angle of the bushing to distribute the pressure on the bushing, so that the upper surface of the bushing is kept level with the horizontal plane, thereby achieving the bushing being kept vertically pressed down into the rear sub-frame sleeve, avoiding the existence of a gap between the bushing and the sleeve, and improving production efficiency.

[0012] A movable gap is left between the connecting column and the hemispherical block and the support cover, which can increase the movable space of the connecting column and better restore the inclination angle of the bushing, which is conducive to keeping the bushing pressed vertically into the rear subframe sleeve.

[0013] The side wall of the base 2 is equipped with a plurality of clamping members 201 for clamping the bottom edge of the support cover. The support cover is clamped by the clamping members and fixed under the base, so that the support cover and the base are relatively fixed, which can prevent the support cover from sliding too much relative to the hemispherical block and falling off.

[0014] A step 202 for placing the connecting plate is provided in the base 2, and a limiting groove 203 is provided on the step 202. A limiting block 701 matching the limiting groove is provided on the edge of the connecting plate 7, which can limit the rotation of the connecting plate relative to the base to avoid sliding interference with the support cover, and can better restore the inclination angle of the adjusting bushing, which is conducive to keeping the bushing vertically pressed down into the rear subframe sleeve.

[0015] The connecting column and the connecting plate are connected by bolts, and the connecting column and the connecting plate are detachably connected by the bolts, which is convenient for assembly or maintenance.
