Abstract
The utility model discloses a drum brake assembly grinding machine tool. The drum brake assembly grinding machine tool comprises grinding heads, wherein the grinding heads and a transmission mechanism assembly are mounted on a vertical column; another grinding head is arranged at the lower end of one grinding head; a digital control sliding table is mounted at the lower part of the machine tool; a rotary working table is mounted on the digital control sliding table; an integral base clamp is mounted on the rotary working table; a brake outer circle to be processed is mounted on the integral base clamp; the grinding heads adopt vertical cylindrical diamond sand strip grinding heads; and the digital control sliding table is mounted on a linear guide rail and connected with a ball screw. The grinding heads adopt vertical cylindrical diamond sand strip grinding heads and can be all in contact with the brake outer circle on an arc generating line, so that the phenomenon of non-uniform local abrasion is avoided, the workpiece stress is uniform and the outer circle run-out of a frictional plate of a brake is effectively guaranteed; and the grinding machine tool is used for processing a drum brake assembly, and the precision requirement of the drum brake assembly is guaranteed.
Description
Technical field
The utility model relates to machining, promptly a kind of drum brake assembly grinding machine.
Background technology
The processing of assembling back is adopted in brake cylindrical processing at present basically; The brake component is fixed on the grinding machine turntable with macropore in the middle of the back-plate and plane positioning; There is the fixedly control slide unit of mill at the turntable rear portion; The adjusting leading screw at control slide unit rear portion is used for regulating slide unit (drive mill) and advances or retreat, and promptly regulates the distance between workpiece and the mill, to guarantee the final size and the form and position tolerance of brake cylindrical.Mill contacts with workpiece is local during grinding, and the brake cylindrical is beated has very big influence, is difficult to the strict demand that guarantees that some product is beated to foreign round for the receive force direction and the wearing and tearing (and wearing and tearing are very inhomogeneous on mill cutter tooth length: low inside and high outside) of mill.
Summary of the invention
For addressing the above problem, the utility model patent has proposed a kind of new design of special vertical numerical control grinding lathe, in order to the processing drum brake assembly, and guarantees its required precision.
This drum brake assembly grinding machine comprises the grinding machine head of lathe, and grinding machine head and transmission mechanism component are installed on the column, and the grinding machine head lower end is a bistrique; Nc sliding table is equipped with in bottom at lathe; Rotary table is housed on the nc sliding table, the unsplit bedplate anchor clamps are housed on the rotary table, brake cylindrical to be processed is housed on the unsplit bedplate anchor clamps; It is characterized in that; Bistrique adopts vertical type cylinder shape diamond emery stick bistrique, and nc sliding table is installed on the line slideway, and links to each other with ball-screw.
Grinding machine head and transmission mechanism component are arranged on the column; Adding the man-hour grinding machine head can move up and down with column; The rotary table of installation brake cylindrical and unsplit bedplate clamps are on nc sliding table; Nc sliding table drives rotary table and moves horizontally, and through the continuous revolution of rotary table, realizes the feed motion in the process again.Add man-hour brake cylindrical and rotate to realize that with rotary table the workpiece feeding accomplishes grinding.
Bistrique adopts vertical type cylinder shape bistrique, adds the man-hour bistrique and can all contact on arc generatrix with the brake cylindrical, has avoided the phenomenon of concentrated wear inequality; And workpiece is stressed evenly to have guaranteed that effectively the cylindrical of brake bush is beated, and bistrique is manufactured and designed by the specialized vendor; Adopt the diamond emery stick, overall structure is in light weight, rigidity is strong, and diamond emery stick and body should be solid and reliable; Running safety, steady, friction.The slide unit that is used to install rotary table and anchor clamps adopts nc sliding table, adopts line slideway and ball-screw transmission, adds workpiece and the accurate location of bistrique in man-hour.
Description of drawings
