Abstract
The invention relates to a hold-down gear for processing brake assemblies. The hold-down gear is composed of a sliding block, a piston cylinder and a pressure plate, wherein the piston cylinder is arranged above the base; a sliding block fixing seat is arranged above the piston cylinder; a cover nut is arranged above the sliding block fixing seat; a tension spring is arranged between the sliding block fixing seat and the cover nut; a screw penetrates through a gasket to be fixed on the sliding block fixing seat; and in an inner cavity formed by the assembly parts, the screw rod penetrates through a piston A, a piston B, the sliding block, a dust retainer ring, a dust retainer ring fixing pressure plate, a pressure plate and an opening pressure plate, and is locked by the nut. By cooperating with a special grinder, the hold-down gear of the invention can be used for carrying out external grinding on brakes the diameter phi of which is 300-500 and the width of which is 80-220. The invention ensures the position degree, shape precision and circular runout within 0.10 mm, and also ensures the verticality with the assembly reference surface within 0.10 mm, thereby enhancing the machining efficiency, improving the braking property and meeting the requirements of a customer.
Description
Technical field: the hold down gag that the present invention relates to a kind of machining brake assembly.
Background technology: brake assembly cylindrical machining accuracy is the main cause that influences product quality always at present, and traditional processing method is to use horizontal lathe, and the customization pressing plate axially presses the hoof facing to finish, and its surface roughness is poor, and cylindricity does not reach requirement.Also there is the borer for drum of employing method for processing to finish, optimized labor style, but its performance-relevant quality level do not improve and improves.Also adopt double-pole frame vertical lathe to divide thick finish turning to finish for twice in recent years, the processing of brake brake-shoe cylindrical friction plate cylinder, precision increases, but its circular arc beats more than 0.30～0.80mm, with the perpendicularity of assembling base plane at 0.30～0.50mm.Cylindrical is beated and perpendicularity is difficult to guarantee, can not satisfy customer requirement.And the dust after the processing is difficult to reclaim, and is scattered in airborne dust granules, and health is caused very big injury.Belonging to harmful pollutes.
Summary of the invention: purpose of the present invention is exactly the hold down gag that a kind of machining brake assembly will be provided, and it cooperates with the special grinding wheel machine, can overcome the existing problem of above product well.The object of the present invention is achieved like this, the hold down gag of machining brake assembly, formed by slide block, piston cylinder, pressing plate, it is characterized in that: base is provided with gas outlet A, the base top is provided with piston cylinder, piston cylinder is provided with air inlet B, the top of piston cylinder is provided with the slide block holder, the slide block holder is provided with air inlet A, the top of slide block holder is provided with blind nut, and between is provided with extension spring, and described extension spring one end is fixed on the alignment pin, the other end is by the pad capping, and screw passes spacers on the slide block holder; In the inner chamber that above component parts forms, screw rod passes piston A, piston B, slide block, dust-blocking ring, dust-blocking ring fixation clip, pressing plate, opening pressing plate from bottom to up, by nut check.The present invention cooperates with the special grinding wheel machine, is applicable to machining brake diameter ф 300～ф 500, all brake cylindricalo grindings of width 80-220.Can guarantee position degree, form accuracy, the circle beat in 0.10mm, with the assembling base plane perpendicularity in 0.10mm.Improve working (machining) efficiency, improved braking ability, reached requirement of client.
Description of drawings: Fig. 1 is a structural representation of the present invention;
1. piston A, 2. piston cylinder, 3. piston B, 4. slide block holder, 5. screw, 6. pad, 7. extension spring, 8. blind nut, 9. pressing plate, 10. opening pressing plate, 11. nuts, 12. screw rods, 13. dust-blocking rings, 14. dust-blocking ring fixation clips, 15. workpiece, 16. slide blocks, 17. bases.
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing;
The hold down gag of machining brake assembly, formed by slide block 16, piston cylinder 2, pressing plate 9, it is characterized in that: base 17 is provided with gas outlet A, base 17 tops are provided with piston cylinder 2, piston cylinder 2 is provided with air inlet B, the top of piston cylinder 2 is provided with slide block holder 4, slide block holder 4 is provided with air inlet A, the top of slide block holder 4 is provided with blind nut 8, between is provided with extension spring 7, described extension spring 7 one ends are fixed on the alignment pin, and the other end is by pad 6 cappings, and screw 5 passes pad 6 and is fixed on the slide block holder 4; In the inner chamber that above component parts forms, screw rod 12 passes piston A1, piston B3, slide block 16, dust-blocking ring 13, dust-blocking ring fixation clip 14, pressing plate 9, opening pressing plate 10 from bottom to up, is locked by nut 11.During concrete enforcement, air inlet B inflation moves on the piston B3, and promotion radially 4 slide blocks 16 is expanded to circumferencial direction, until tensioner brake assembly endoporus.Piston A1 moves down simultaneously, compresses brake assembly base plate end face by pressing plate 9, reaches precise positioning and clamping reliably, after the completion of processing, air inlet A inflation moves on the piston A1, unclamp clamping platen 9, piston B3 moves down simultaneously, and radial slider 16 is subjected to extension spring 7 active forces and moves to the center of circle.Brake assembly can conveniently take off, and changes next product.
