Description
Technical field
This utility model relates to brake drum brake lining finishing technology field, a kind of clamping device for brake drum.
Background technology
Brake drum is gray iron casting, a kind of large-caliber thin-shell drum-shaped shape, typically weighs about 30～70 kilograms.
Owing to brake drum belongs to security part, the accuracy of form and position and geometric accuracy to it require the highest, and the particularly requirement of the accuracy of form and position of brake drum brake lining is improving year by year.At present in conventional fabrication process, typically take to position with installing seam with brake drum baseplane, polish brake lining, but due to the precision of lathe during processing, particularly the variation of seam processing, all produces impact to the brake lining accuracy of form and position, causes conforming product rate to reduce.
Utility model content
In view of this, this utility model provides a kind of clamping device for brake drum.
A kind of clamping device for brake drum, it includes a pedestal, multiple contour screw, a disc spring, a cushion block, a hold down gag and a mandrel；
Pedestal is positioned at bottom；Mandrel is located in the center of pedestal, and arbor portions stretches out outside pedestal；Disc spring is positioned at above pedestal, and disc spring is set on mandrel；Cushion block is positioned at above mandrel；Hold down gag is positioned at above cushion block；Contour screw is fixed on pedestal surrounding.
Described in the utility model in the clamping device of brake drum, the most uniform grooving being provided with multiple tracks in described disc spring.
Described in the utility model in the clamping device of brake drum, described grooving is 12 roads.
Described in the utility model in the clamping device of brake drum, described disc spring be set on mandrel and with mandrel sliding connection.
Described in the utility model in the clamping device of brake drum, described hold down gag is clamping nut.
Described in the utility model in the clamping device of brake drum, described contour screw pedestal surrounding is uniformly distributed.
The clamping device for brake drum that this utility model provides compared with prior art, has an advantage in that: pedestal is fastened by bolts device and is fastenedly connected with machine tool chief axis.Fit with contour screw in brake drum bottom surface, brake drum seam and disc spring external diameter sliding contact, and by the mechanical force certain to clamping nut, power is passed through cushion block, is delivered in disc spring, and disc spring under force, occurs elastic deformation, the most outwards distending.Fully fit with brake drum seam inwall, eliminate the impact on Product Precision that is deteriorated of brake drum seam processing dimension.After brake drum machines, to one contrary mechanical force of clamping nut, disc spring, under the effect of elastic force, bounces back, completes the release of workpiece.This utility model device improves the precision of Product processing, improves the qualification rate of product.

Detailed description of the invention
As shown in Figure 1, 2, at a kind of clamping device for brake drum of this utility model embodiment, it includes a pedestal 1, multiple contour screw 2, disc spring 3, cushion block 4, hold down gag and a mandrel 6.
Pedestal 1 is positioned at bottom；Mandrel 6 is located in the center of pedestal 1, and mandrel 6 part is stretched out outside pedestal 1；Disc spring 3 is positioned at above pedestal 1, and disc spring 3 is set on mandrel 6；Cushion block 4 is positioned at above mandrel 6；Hold down gag is positioned at above cushion block 4；Contour screw 2 is fixed on pedestal 1 surrounding.
Alternatively, in the clamping device for brake drum described in this utility model embodiment, described mandrel 6 is mould steel, after Overheating Treatment, the position that mandrel 6 and disc spring 3 are slidably matched processes with special tool on lathe, reduces the precision impact on product of lathe to greatest extent.
Alternatively, in the clamping device for brake drum described in this utility model embodiment, described disc spring 3 is high manganese steel, forged after be machined into, add the durability of this device.
Alternatively, in the clamping device for brake drum described in this utility model embodiment, the most uniform grooving being provided with multiple tracks in described disc spring 3.The scope of work can be increased, decrease labor strength, with the impact on Product Precision that is deteriorated effectively eliminating brake drum seam processing dimension.
Alternatively, in the clamping device for brake drum described in this utility model embodiment, described grooving is 12 roads.The use of grooving adds the area of the transmission of power, makes the stability of equipment improve.
Alternatively, in the clamping device for brake drum described in this utility model embodiment, described disc spring 3 be set on mandrel 6 and with mandrel 6 sliding connection.
Alternatively, in the clamping device for brake drum described in this utility model embodiment, described hold down gag is clamping nut 5.
Alternatively, in the clamping device for brake drum described in this utility model embodiment, described contour screw 2 pedestal 1 surrounding is uniformly distributed.Alternatively, having three contour screws, uniform along horizontal circle circumferential direction, it efficiently reduces the impact on workpiece accuracy of the impurity such as iron filings, dust.
The clamping device for brake drum that this utility model provides compared with prior art, has an advantage in that: pedestal 1 is fastened by bolts device and is fastenedly connected with machine tool chief axis.Fit with contour screw in brake drum 7 bottom surface, brake drum 7 seam and disc spring 3 external diameter sliding contact, and by the mechanical force certain to clamping nut 5, power is passed through cushion block 4, is delivered in disc spring 3, and disc spring 3 under force, occurs elastic deformation, the most outwards distending.Fully fit with brake drum 7 seam inwall, eliminate the impact on Product Precision that is deteriorated of brake drum 7 seam processing dimension.After brake drum 7 machines, to 5 one contrary mechanical forces of clamping nut, disc spring 3, under the effect of elastic force, bounces back, completes the release of workpiece.This utility model device improves the precision of Product processing, improves the qualification rate of product, creates efficiency, covert reduction production cost for enterprise.
It is understood that for the person of ordinary skill of the art, other various corresponding changes and deformation can be made according to technology of the present utility model design, and all these change all should belong to this utility model scope of the claims with deformation.
