Abstract

The utility model discloses a clamp floating centring device for lathing and milling processed castings. The device is used for limiting the motion of a workpiece in the horizontal direction by employing a V-shaped centring block, thereby ensuring that the centre of the appearance of the workpiece is consistent with the processed centre; a spring is arranged between the V-shaped centring block and a clamp chassis, thereby realizing the free motion of the spring in the vertical direction and further realizing the role of centring a V-shaped groove in the case of different overall dimensions of the castings; an angular positioning dowel is used for limiting the horizontal rotation direction of the V-shaped centring block and capable of limiting the workpiece at the horizontal position to any angle position. The floating centring device of the utility model is simple in structure, practical and efficient.

Description

Car, the anchor clamps that mill the processing foundry goods centring means that floats

Technical field

The utility model relates to machining, car when applying to production cast-iron blank class part, the unsteady location of milling the clamp for machining workpiece.

Background technology

Along with the manufacturing development of China, increasing part adopts casting technique, though be cast with lot of advantages, deficiency is arranged also; Such as the mould shift that produces in the casting, the case that rises etc. phenomenon, causes air spots; Workpiece 1 center is difficult to confirm that appearance and size differs, and impacts for the location of back machining; Adopt the adjective-centre structure (structure is as depicted in figs. 1 and 2) of prior art, produce the workpiece centre skew of processing, need constantly adjustment; Influence the utilization of process equipment, effect is not high, also increases the percent defective of workpiece.

Summary of the invention

The utility model order ground is to overcome foundry goods part processing center and the blank shape off-centring is excessive, and a kind of centring means that is applicable to that lathe, milling machine clamp for machining float is provided.

In order to achieve the above object, a kind of car that the utility model provides, the anchor clamps that mill the processing foundry goods centring means that floats, comprising: the anchor clamps chassis is equipped with the V-arrangement center bridge with V-shaped groove structure on the said anchor clamps chassis.

Wherein, said V-arrangement center bridge is fixed on the anchor clamps chassis through guide pillar, and on the spring housing guide pillar, spring one end is packed in the anchor clamps locating hole on the anchor clamps chassis, and the other end is resisted against V-arrangement center bridge bottom.

Wherein, the part that said guide pillar is arranged in the anchor clamps chassis is provided with keyway, and the angle alignment pin penetrates keyway with V-arrangement center bridge horizontal fixed.

Utilize the moving of horizontal direction of V-arrangement center bridge restriction workpiece, be consistent with the profile center that guarantees workpiece and the center of processing.

A spring is housed between V-arrangement center bridge and the anchor clamps chassis, realizes moving freely of its vertical direction, to guarantee that the foundry goods profile under the situation that size differs, realizes the centering effect of V-shaped groove.

The angle alignment pin is used to limit V-arrangement center bridge horizontal rotatio direction, can be with the workspace limits of horizontal level at any angle orientation.

The centring means that the utility model floats, simple in structure, practicality and high efficiency.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

Accompanying drawing sign: 1-workpiece; 2-V shape center bridge; The 3-spring; 4-anchor clamps chassis; 5-angle alignment pin.

Please with reference to Fig. 3 and Fig. 4.The car of present embodiment, the unsteady location of milling clamp for machining, this centring means that floats mainly is made up of V-arrangement center bridge 2, spring 3, angle alignment pin 5, anchor clamps chassis 4.The V-shaped groove of V-arrangement center bridge is used for the horizontal direction location; The location of vertical direction is confirmed in the combination of V-arrangement center bridge and spring; The angle alignment pin is used to prevent horizontally rotating of V-arrangement locating piece, and factors such as the mould shift when this device is greatly avoided cast-iron blank because of casting, the case that rises are to the blank location influence, and accurate positioning, quick; The location does not receive the blank appearance effects, has improved the production work efficiency greatly.

Above content is the further explain that combines optimal technical scheme that the utility model is done, and can not assert that the practical implementation of utility model only limits to these explanations.Under the utility model, the those of ordinary skill of technical field, under the prerequisite of the design that does not break away from the utility model, can also make simple deduction and replacement, all should be regarded as the protection domain of the utility model.
