Abstract
The utility model discloses a chuck structure capable of automatically finishing groove parts of boxes, which comprises a clamp body, a cylindrical pin (8), a cross-shaped spherical drive key, an earring drive shaft, a compression spring, a sleeve barrel, a cylindrical pin (7), a cylindrical pin (9) and a grinding sleeve, wherein the clamp body is arranged on a drill press spindle, the cross-shaped spherical drive key is connected to the clamp body through the cylindrical pin (8), and the cross-shaped spherical drive key and the cylindrical pin (8) can rotate around the clamp body; the earring drive shaft is connected with the cross-shaped spherical drive key through the cylindrical pin (8), and the sleeve barrel is connected with the earring drive shaft through the cylindrical pin (7); and the sleeve barrel is connected with the grinding sleeve through the cylindrical pin (9). The compression spring is fixed between the sleeve barrel and the earring drive shaft, and the compression spring can slide freely on the earring drive shaft. The cylindrical pin (7) on the sleeve barrel can slide freely in the axial direction. The structure can automatically adjust the arbitrary clamping of parts in the process of grinding the bottom of a groove of the end face of a box, thereby ensuring the flatness of a surface, attached to the bottom of the groove, of the grinding sleeve, effectively improving the machining accuracies of grooves of the end faces of workpieces and the bottoms of the grooves, and improving the operating efficiency.
Description
Technical field
The utility model belongs to the machine tool field, relates to a kind of chuck structure of repairing casing, but relates in particular to the chuck structure at a kind of automatic dressing casing groove position.
Background technology
At present; Mechanical Manufacturing Enterprises in China, along with the raising that processing precision of products is required, especially for dimensional accuracy, surface configuration precision and the surface smoothness of cabinet workpiece surface groove, bottom land and stepped hole bottom land require increasingly high; And be that the cutter of its end face, groove processing is more special; It is bigger to add the man-hour difficulty at the end face grooving, and the sharpening of cutter is difficulty relatively also, especially for the bigger surface groove of the degree of depth; Cutter adds easy generation vibration in man-hour even fractures, and makes that workpiece size precision, surface configuration, the surface smoothness of being processed all are difficult for guaranteeing.Therefore, development a kind ofly can effectively improve workpiece end face groove processing precision, the processing unit (plant) that increases substantially operating efficiency is very important.
The utility model content
But the purpose of the utility model be to provide a kind of simple in structure, easy to operate, can effectively improve parts surface groove machining accuracy, the chuck structure at the automatic dressing casing groove position of increasing work efficiency.
The technical scheme of the utility model is: but the chuck structure at automatic dressing casing groove position comprises; Chuck body, straight pin, cross sphere driving key, earrings power transmission shaft, compression spring, cover bucket, straight pin, straight pin, grinding sleeve; Chuck body is contained on the drill press spindle, and cross sphere driving key is connected on the chuck body through straight pin, and cross sphere driving key, straight pin can rotate around chuck body; The earrings power transmission shaft is connected with cross sphere driving key through straight pin, and the cover bucket is connected with the earrings power transmission shaft through straight pin; The cover bucket is connected with grinding sleeve through straight pin.
Between cover bucket and earrings power transmission shaft, be fixed with the compression spring, the compression spring can be free to slide on the earrings power transmission shaft.
Straight pin on the cover bucket axially can be free to slide.
The utility model can reach following good effect after adopting technique scheme: owing to can adjust the random clamping of part when grinding casing surface groove bottom land automatically; Grinding sleeve can be according to external diameter, the width dimensions processing of workpiece groove and stepped hole; Guarantee that grinding sleeve and groove bottom land binding face are smooth, and do not have other Geometrical Tolerance Principle.And grinding sleeve can use for a long time.Effectively improve the machining accuracy of workpiece end face groove and bottom land, improved operating efficiency.
Description of drawings
But Fig. 1 is the structural representation of the chuck structure at the utility model automatic dressing casing groove position.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description.As shown in Figure 1, but the chuck structure at automatic dressing casing groove position comprises: chuck body 1, straight pin 8, cross sphere driving key 2, earrings power transmission shaft 3, compression spring 5, cover bucket 4, straight pin 7, straight pin 9, grinding sleeve 6.Chuck body 1 is contained on the drill press spindle, and cross sphere driving key 2 is connected on the chuck body 1 through straight pin 8, and cross sphere driving key 2, straight pin 8 can rotate around chuck body 1; Earrings power transmission shaft 3 is connected with cross sphere driving key 2 through straight pin 8, and cover bucket 4 is connected with earrings power transmission shaft 3 through straight pin 7; Compression spring 5 is fixed between cover bucket 4 and the earrings power transmission shaft 3.Cover bucket 4 is connected with grinding sleeve 6 through straight pin 9.Cross sphere driving key 2, straight pin 8 should rotate flexibly when assembling with earrings power transmission shaft 3.Straight pin 7 axially should be free to slide at cover bucket 4, and compression spring 5 can be free to slide on earrings power transmission shaft 3.
Be contained on the drill press spindle chuck body 1 and through cross sphere driving key 2 power passed to earrings power transmission shaft 3, earrings power transmission shaft 3 is passed to cover bucket 4 through straight pin 7 with power, and cover bucket 4 is passed to grinding sleeve 6 through straight pin 9 with power.Hole on straight pin 8 and chuck body 1, the earrings power transmission shaft 3 is an interference fit; Hole on straight pin 8 and the cross sphere driving key 2 is a matched in clearance; Rotate flexibly, can guarantee that like this grinding sleeve 6 spatially has certain amount of floating, be adjacent to workpiece end face groove bottom land and stepped hole bottom land automatically.Straight pin 7 is matched in clearance with cover bucket 4; Axially can be free to slide, compression spring 5 can be free to slide on earrings power transmission shaft 3, through the drill press spindle axial feed; Compression spring 5 is compressed; Cover bucket 4 passes through straight pin 9 and slides at earrings power transmission shaft 3, and grinding sleeve 6 is produced certain pressure, can compensate the gap that grinding sleeve 6 wearing and tearing backs and workpiece end face groove bottom land or stepped hole bottom land produce automatically.Can guarantee that like this grinding sleeve 6 is adjacent to workpiece end face groove bottom land or stepped hole bottom land automatically.Hole on the cover bucket 4 is identical with the hole pitch-row on the grinding sleeve 6, and straight pin 9 is an interference fit with the hole of overlapping on the bucket 4.Hole on straight pin 9 and the grinding sleeve 6 is a matched in clearance.Grinding sleeve 6 can not only can grind flat workpiece end face groove bottom land and stepped hole bottom land according to the different size or the shape processing of workpiece groove or stepped hole, and can grinded curved surface workpiece bottom land and chamfering.To the bigger workpiece of last process groove bottom land mismachining tolerance, can change grinding sleeve 6 into cutter hub that blade is housed, as long as guarantee that the hole on the cutter hub is identical with the hole on the grinding sleeve 6.Eliminate error with this cutter hub, and then grind.Can enhance productivity like this, guarantee the machining accuracy of workpiece.
