Abstract
The invention relates to the technical field of automotive brake pads, in particular to a high-speed high-precision rough grinding wheel of an automotive brake pad. The high-speed high-precision rough grinding wheel comprises a cylindrical grinding wheel basal body and a barrel which is integrated with the cylindrical grinding wheel basal body, wherein a through flat key shaft hole is arranged in the shaft center of the cylindrical grinding wheel basal body; and diamond grinding particles and crossed spiral chip removal grooves are arranged on the outer wall of the barrel. A plurality of weight-reducing through holes which are uniformly arranged around the flat key shaft hole are arranged in the cylindrical grinding wheel basal body. The length of the cylindrical grinding wheel basal body is smaller than that of the barrel, and the transverse center line of the cylindrical grinding wheel basal body is superposed with the transverse center line of the barrel. The high-speed high-precision rough grinding wheel is used for grinding by rotating with the adoption of a double-helix crossed cutting mode, is good in chip removal effect, is high in cutting speed, and can grind the surface of a product at a high speed, so that the product precision is relatively high, groove marks are avoided, and the product flatness can be guaranteed to be within 0.2mm.
Description
(1) technical field
The present invention relates to automobile brake sheet field, particularly a kind of automobile brake sheet high-speed, high precision rough grinding wheel.
(2) background technology
Material is put into the disc brake pad semi-finished product of hot press grinding tool chamber hot pressing, the depth of parallelism on its surface is lower.Semi-finished product generally can not directly be assemblied in automobile brake system, otherwise easily generation brake block Pian Brake affects braking ability.Therefore, the semi-finished product after hot pressing need through grinding action, then through packaging processes such as spraying, riveted joints, are finally dealt in client's hand.
The area of brake block grinding is generally 1800-30000mm, and the degree of depth is the speed 50-150mm/s of 1-3mm, grinding.In order to ensure product depth of parallelism 0.2mm, general needs roughly grinds and fine grinding two procedures.Corase grind mainly grinds away the product subsurface of hot pressing, ensures the drawing requirement processing dimension of product, is convenient to the depth of parallelism correction of follow-up fine grinding.
At present, what use during corase grind is generally disc type rough grinding wheel, and its feature grinding accuracy is high, but under equal grinding area, grinding depth is generally 0.5-1mm; The cartridge type rhombus groove emery wheel general grinding degree of depth is comparatively large, but grinding accuracy is lower, the general 0.3m of the depth of parallelism of abrasive product under equal grinding area; Cartridge type generally there will be deep trench mass defect at product surface without chip area emery wheel.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides that a kind of grinding depth is large, grinding accuracy is high, without the automobile brake sheet high-speed, high precision rough grinding wheel of groove mark.
The present invention is achieved through the following technical solutions:
A kind of automobile brake sheet high-speed, high precision rough grinding wheel, it is characterized in that, the cylindrical shell comprising cylinder emery wheel matrix and be made into integration with it, the axle center of described cylinder emery wheel matrix is provided with the flat key axis hole run through, and described cylinder body outer wall is provided with diamond grinding particle and debris groove arranged in a crossed manner.
Described cylinder emery wheel matrix is provided with some loss of weight through holes be evenly arranged around flat key axis hole.
The length of described cylinder emery wheel matrix is less than the length of described cylindrical shell, and their cross central line overlaps.
The invention has the beneficial effects as follows:
The present invention adopts the mode of double helix cross-cut to rotate and forms, and its chip removal is effective, and cutting speed is fast, and can meet the high-speed grinding product surface of product, Product Precision is higher, without groove mark, within can ensureing product Pingdu 0.2mm.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is main TV structure schematic diagram of the present invention;
Fig. 2 is left TV structure schematic diagram of the present invention;
Fig. 3 is right TV structure schematic diagram of the present invention;
Fig. 4 is vertical profile structural representation of the present invention.
In figure, 1 cylinder emery wheel matrix, 2 cylindrical shells, 3 flat key axis holes, 4 loss of weight through holes, 5 diamond grinding particles, 6 debris grooves, 7 diamond blocks.
(5) detailed description of the invention
Accompanying drawing is specific embodiments of the invention.As shown in Figures 1 to 4, this kind of automobile brake sheet high-speed, high precision rough grinding wheel, comprise cylinder emery wheel matrix 1 and cylindrical shell 2, cylinder emery wheel matrix 1 is positioned at cylindrical shell 2 and is made into integration with cylindrical shell 2, the length of cylinder emery wheel matrix 1 is less than the length of cylindrical shell 2, and their cross central line overlaps, and the axle center of cylinder emery wheel matrix 1 has the flat key axis hole 3 and some loss of weight through holes 4 that run through, and loss of weight through hole 4 is evenly arranged around flat key axis hole 3; Cylindrical shell 2 outer wall is embedded with diamond grinding particle 5, also has debris groove 6 arranged in a crossed manner simultaneously, the outer wall of cylindrical shell 2 is divided into several diamond blocks 7 by these debris grooves 6 arranged in a crossed manner.
Brake block is positioned on workbench, be translated across the present invention of High Rotation Speed, rotate under the drive of the turning cylinder of motor, the linear velocity being embedded in the diamond grinding particle 5 on cylindrical shell 2 can reach 315000-320000mm/s, can grind away by the brake pad material being 1-3mm 1800-30000mm, the degree of depth per second, the depth of parallelism of its plane is less than 0.2mm, reaches high speed, high accuracy corase grind auto parts machinery brake block.
When diamond grinding particle 5 on each diamond block 7 contacts brake pad material, be all first contact brake block by the front summit of diamond block, be then progressively transitioned into the summit, two limits on limit, left and right, finally contact summit backmost.The scrap of such grinding can slide to front, left front and right front along with the limit of diamond block 7, and the scrap stopped when only sliding to front extrudes the ditch trace problem caused.When slipping over summit, limit, left and right, grinding scrap can have relative tendency toward sliding with the limit, left and right of diamond block to right back and left back, due to the very fast grindstone dust of grinding wheel speed or proal, because part relative velocity ensure that not overstocking with decentralized of scrap, prevent because scrap overstocks the grinding ditch trace problem caused.
The present invention carries out a large amount of grinding primarily of diamond grinding particle 5, debris groove 6 carries out a large amount of chip removal in time, ensures high speed, the high-precision grinding of emery wheel, prevents the generation of grinding groove mark.
Except technical characteristic described in description, all the other technical characteristics are those skilled in the art's known technology.
