Description

Technical Field

[0001] The utility model relates to the technical field of brake disc detection fixtures, in particular to a brake disc dynamic balance detection fixture. Background Art

[0002] The brake disc, in simple terms, is a round plate that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car. The brake disc has a good braking effect and is easier to maintain than drum brakes.

[0003] During the processing of brake discs, they are generally tested for dynamic balancing. Dynamic balancing requires a special dynamic balancing machine to detect the imbalance. The dynamic balancing machine generally needs to use a fixture to clamp the workpiece and then test it. For example, the Chinese utility model patent with announcement number CN221123688U specifically discloses a brake disc dynamic balancing test fixture.

[0004] However, during actual use of the brake disc dynamic balance detection fixture, people will find that the brake disc is locked on the fixture body by a large number of bolts. This fixing method is very cumbersome and each detection requires a lot of time to disassemble and assemble the bolts, which is very inconvenient to use. Utility Model Content

The movable block and the spring are both arranged in the movable groove. The movable block is slidably connected in the movable groove. The two ends of the spring are respectively connected to the movable block and the inner wall of the movable groove. When the outer support mechanism pushes the limiting mechanism outward, the movable block will be driven to squeeze the spring. When the outer support mechanism moves upward to release the limiting mechanism, the spring rebounds, which will drive the limiting mechanism to move back.

[0009] The limiting mechanism includes a connecting plate, a shovel plate, a support column, a screw rod, a slider and a pressure block. The connecting plate is connected to the movable block, the shovel plate and the support column are fixed above the connecting plate, a slide groove is provided on the support column, the screw rod is arranged in the slide groove, the end of the screw rod is hinged to the support column, the top of the screw rod passes through the support column, the screw rod is threadedly connected to the slider, and the slider is provided with a pressure block; the limiting mechanism is pushed outward by using the external support mechanism, so that the support column on the limiting mechanism is supported on the brake disc, and then the screw rod is rotated, and the pressure block on the slider is driven downward by the screw rod, and the brake disc is pressed by the pressure block.

[0010] Preferably, a brake disc mounting ring is provided on the outer side of the middle seat, and a plurality of positioning blocks are provided on the brake disc mounting ring. The positioning blocks are mainly used to cooperate with the bolt holes on the brake disc to achieve a positioning effect when placing the brake disc.

[0011] Preferably, the slider is fitted with the inner wall of the slide groove, and a sliding connection is adopted between the slider and the slide groove, and the slide groove is used to limit the slider to prevent the slider from rotating along with the screw rod.

[0012] Preferably, a knob is fixed on the top of the screw rod, and the knob is mainly provided to facilitate the staff to rotate the screw rod.

[0013] Preferably, the connecting plate is fixed to the movable block by bolts to facilitate later dismantling and maintenance.

[0014] Preferably, the support column and the pressure block are both provided with rubber pads for preventing the support column, the pressure block and the brake disc from having hard contact.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model pushes the limiting mechanism outward by moving the conical sleeve on the outer support mechanism downward, and uses the support column on the limiting mechanism to support the brake disc, thereby preliminarily fixing the brake disc, and then rotating the screw rod, using the screw rod to drive the slider to move downward, so that the brake disc is pressed by the pressure block on the slider, thereby clamping and fixing the brake disc. When removing, the conical sleeve on the outer support mechanism is moved upward, and the limiting mechanism is reset by the reset mechanism, and the fixation of the brake disc is cancelled, so that it can be removed. The operation is simple and movable, and the brake disc is very convenient to disassemble and assemble, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
