DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-5 In the embodiments of the utility model, a honing quick-change clamp device for brake pump cylinder body comprises a turntable 2 and a plurality of clamp mechanisms 3 arranged on the turntable 2. The number of the clamp mechanisms 3 is not limited. In the embodiments, the number of the clamp mechanisms 3 is five. The five clamp mechanisms 3 correspond to the processes of feeding and discharging, rough honing, fine honing, deburring and measuring respectively. The clamp mechanism 3 comprises a first support 31 arranged on the turntable 2 and a seat 32 arranged on the first support 31. The seat 32 is provided with a clamping assembly 33 for fixing a workpiece to be processed. The opening and closing of the clamping assembly 33 are controlled by an opening and closing mechanism 4 connected to the clamping assembly 33. The clamping assembly 33 comprises movable arms 331 arranged symmetrically on the seat 32. The same side end portions of the two movable arms 331 are fixed to the seat 32 by positioning pins. When the movable arms 331 rotate, they rotate around the outer periphery of the positioning pins as the center point. The end portions on the other side of the two movable arms 331 are connected by a return spring 333. The two movable arms 331 are provided with clamping jaws 332 for clamping the outer periphery of the workpiece to be processed. The clamping jaws 332 can adapt to and clamp workpieces to be processed of different sizes by the extensibility of the return spring 333. The elasticity of the return spring 333 enables the clamping jaws 332 to automatically adjust the clamping force and position according to the actual size of the workpiece, so that each workpiece to be processed can be stably clamped. This design not only improves the versatility and flexibility of the clamp, but also ensures the stability and reliability when processing workpieces to be processed of various specifications. When the specifications of the honing workpieces to be processed change, the entire clamp mechanism 3 does not need to be replaced. Only the limiting block 5 matched with the specific workpiece needs to be replaced. This design simplifies the operation process, greatly reduces the time required for replacing the clamp, and improves the work efficiency.

The base 6 is installed on the rack 1, and the power box 7 is installed on the base 6. The end of the power box 7 is connected with the bottom of the rotating disc 2 and drives the rotating disc 2 to rotate. The design of the rack 1 not only provides stable support for the opening and closing mechanism 4, the base 6 and the power box 7, but also ensures that the relative position relationship between the opening and closing mechanism 4 and the rotating disc 2 is accurately limited, thereby ensuring the stability and reliability of the whole system.
