Abstract
The utility model discloses a fixture floating centering device of a drilling and milling machining casting. In the fixture floating centering device of the drilling and milling machining casting, a positioning ring with tapers is utilized for limiting movement of a workpiece in a horizontal plane to ensure that the appearance center of the workpiece is consistent with the required center. Four springs are arranged between the positioning ring with tapers and a positioning disk to realize free upward and downward movement in the vertical direction so as to ensure that centering action of the positioning ring is realized under the condition that sizes of the appearances of the castings are different. Limit pins are used for controlling the positioning ring to rotate in the horizontal direction and move vertically. An air vent below the positioning disk is used for venting the air. The fixture floating centering device of the drilling and milling machining casting has simple structure and is practical and efficient.
Description
Technical field
The utility model relates to machining, the unsteady location of bore when applying to production cast-iron blank class part, 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, and appearance and size differs; The adjective-centre structure of employing shown in Fig. 1 to 2, workpiece centre are difficult to confirm, impact for the location of back machining, 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 brill, milling machine clamp for machining float that provides is simple in structure, practicality and high efficiency.
In order to achieve the above object, a kind of brill that the utility model provides, the anchor clamps that mill the processing foundry goods centring means that floats comprises: have the positioning disk of cannelure and be arranged at the locating ring that top in the cannelure has tapering.
Wherein, the annulus of said locating ring bottom is provided with spring eye, and an end of spring is resisted against in the spring eye, and the other end is resisted against in the cannelure of positioning disk.
Wherein, the said locating ring outside is provided with keyway, and spacer pin passes the outside on the positioning disk, passes through keyway with the locating ring horizontal fixed.
Wherein, be provided with steam vent below the said positioning disk.
Beneficial effect: the locating ring restriction workpiece that the utility model utilization has tapering moves in horizontal plane, is consistent with profile center and the needed center that guarantees workpiece; Have between locating ring and the positioning disk of tapering four springs are housed, realize that the easy on and off of its vertical direction moves, to guarantee that the foundry goods profile under the situation that size differs, realizes the centering effect of locating ring; Spacer pin is used to control the rotation of locating ring horizontal direction and moves up and down.Steam vent hole, positioning disk below is used for deaeration.The centring means that the utility model floats, simple in structure, practicality and high efficiency.
Description of drawings
The adjective-centre structure front view that Fig. 1 adopts for prior art.
The adjective-centre structure vertical view that Fig. 2 adopts for prior art.
Fig. 3 is the brill of the utility model, the anchor clamps that mill the processing foundry goods centring means cutaway view that floats.
Fig. 4 is the brill of the utility model, the anchor clamps that mill the processing foundry goods centring means vertical view that floats.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Accompanying drawing sign: 1-workpiece; The 2-locating ring; The 3-spring; The 4-spacer pin; The 5-positioning disk.
The brill of present embodiment, mill the clamp for machining centring means (seeing Fig. 3 and Fig. 4) that floats and mainly form by the locating ring that has tapering, spring, angle alignment pin, positioning disk.The locating ring that has tapering is used for the horizontal direction location; The combination that has locating ring and the spring of tapering confirms that the location of vertical direction, spacer pin are used to prevent to have the horizontally rotating and the control of upper-lower position of locating ring of tapering, and the aperture on the positioning disk is used for exhaust; 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 to combine optimal technical scheme to the further explain that the present invention did, and can not assert that the practical implementation of invention only limits to these explanations.Under the present invention, the those of ordinary skill of technical field, under the prerequisite that does not break away from design of the present invention, simple deduction and replacement can also be made, all protection scope of the present invention should be regarded as.
