Turning machining clamp for middle disc surface of brake bottom plate

Abstract

The invention relates to the technical field of tool clamps, in particular to a turning machining clamp for a middle disc surface of a brake bottom plate. The turning machining clamp comprises a base,a double-head screw and a bolt, wherein a fixing block is arranged at one end of the base, the double-head screw penetrates through a cam shaft hole of the brake bottom plate to be fixedly connectedwith the fixing block, the other end of the base is provided with a lateral positioning block and two supporting blocks, the side part of the supporting block is provided with an L-shaped pressing plate. The double-head screw and the fixing block are used for fixing one end of the brake bottom plate, the L-shaped pressing plate supporting block is used for fixing the other end of the brake bottomplate, then the center hole of the disc part of the brake bottom plate and the outer side face of the disc part are machined, then the inner side surface of the reverse hook cutter head part is utilized, machining of the two faces and the center hole adopts a positioning reference, the two surfaces of the annular disc surface of the braking bottom plate can be guaranteed to have relatively high parallelism, meanwhile, and the axis of the central hole and the annular disc surface can be ensured to have relatively high perpendicularity. According to the turning machining clamp for the middle disc surface of the brake bottom plate, the design is reasonable, the structure is simple, and the machining precision and quality of the brake bottom plate are improved.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a turning fixture for the disc surface of the middle part of a brake bottom plate. Background technique [0002] The automobile braking system is mainly composed of a brake drum, a brake base plate, a brake shoe, a brake transmission mechanism, etc. The brake base plate is the installation base of various parts in the automobile brake system. The braking principle of the automobile braking system is mainly to press the brake shoe on the inner side of the brake drum through the brake transmission mechanism, and the braking force generated by the friction of the shoe and the brake drum is transmitted to the brake bottom plate, and then Make the wheels slow down according to actual needs, or stop within the shortest distance to ensure driving safety. The brake base plate is the main force-bearing part in the automobile braking system and needs to bear a large load. Therefore, the ...

Problems solved by technology

Using multiple sets of fixtures to process separately is not only complicated, time-consuming and labor-intensive, but also due to the different fixed references of each fixture, it is difficult to ensure the parallelism of the two sides of the annular disk surface. The perpendicularity of the central hole axis and the annular disk surface affects the machining accuracy of the brake bottom plate.
