Description

Technical Field

[0001] This utility model relates to the technical field of brake clamp body processing, and in particular to an automatic alignment fixture for brake clamp body processing. Background Technology

[0002] The brake caliper is the core load-bearing and functional component of a disc brake. It is mainly used to install components such as brake friction pads and brake pistons, and to achieve braking action through hydraulic or pneumatic drive.

[0003] In the current machining process of brake clamp bodies, the positioning and alignment of the fixture are crucial steps to ensure machining accuracy. Traditional fixtures mostly adopt rigid positioning structures, achieving positioning by fixing positioning blocks and pins to fit with the workpiece's reference surface (such as the bottom or side surface) or reference holes, and relying on manual pre-assembly for alignment. When manually positioning and aligning the brake clamp body, tools such as dial gauges and feeler gauges are typically used to adjust the position of the brake clamp body, and the alignment accuracy is greatly affected by the operator's experience.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems: The existing brake caliper clamps rely heavily on the operator's experience for positioning and aligning the brake caliper, which affects work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic alignment fixture for brake caliper body processing, which solves the technical problem that existing brake caliper body fixtures rely heavily on the operator's experience for positioning and alignment, thus affecting work efficiency.

[0006] Utility model solution: This utility model provides an automatic alignment fixture for machining brake clamp bodies, including a worktable, a first fixture seat, a second fixture seat, and a transmission assembly. The worktable has a mounting groove. The first fixture seat and the second fixture seat are symmetrically arranged in the mounting groove. The first fixture seat has a first threaded hole, a first support bracket, a first movable fixture, and a first fixed fixture. The second fixture seat has a second threaded hole, a second support bracket, a second movable fixture, and a second fixed fixture. The transmission assembly includes a motor and a threaded rod. The motor is mounted on the worktable, and the threaded rod has a left-hand thread and a right-hand thread. The left-hand thread is adapted to the first threaded hole, and the right-hand thread is adapted to the second threaded hole.

[0007] Furthermore, a support base is connected below the first support bracket.

[0008] Furthermore, the first movable clamp includes a limiting cylinder, a spring, a limiting member, and a cylinder cover; the spring is disposed inside the limiting cylinder, the limiting member is inserted into the limiting cylinder, and the cylinder cover is threadedly connected to the limiting cylinder.

[0009] Furthermore, the first fixing clamp is bonded with a gasket.

[0010] Furthermore, a limiting post is provided in the mounting groove, and the limiting post passes through the first clamp seat and the second clamp seat.

[0011] Furthermore, a central prompt bar is provided above the workbench.

[0012] Beneficial effects: This invention provides an automatic alignment fixture for machining brake calipers. In use, the brake caliper is placed with its opening facing upwards on the first and second support brackets. The motor is started, driving a threaded rod to rotate. This threaded rod causes the first and second clamping brackets to move simultaneously towards the center. The first and second movable clamping brackets first contact the brake caliper, clamping it once. Then, as the first and second clamping brackets continue to move towards the center, the first and second fixed clamping brackets further clamp the brake caliper. After this clamping, the center plane of the brake caliper coincides with the symmetrical plane between the first and second clamping brackets, facilitating the positioning and alignment of the brake caliper. Therefore, this automatic alignment fixture for machining brake calipers is convenient for positioning and aligning brake calipers, requires less reliance on operator experience, and improves work efficiency.
