Abstract
The utility model discloses a general combined expanding mandrel, which comprises a mandrel. The mandrel comprises a small-diameter section, a middle conical section and a large-diameter section. The small-diameter section is provided with a gland via thread, the small-diameter section is further slidably provided with a front supporting plate, the gland contacts with the front supporting plate, the front supporting plate is fixedly connected with one end of a supporting ring, the other end of the supporting ring is fixedly connected with a rear supporting plate, the rear supporting plate is slidably mounted on the large-diameter section, at least three radial slide grooves are arranged on the supporting ring, a slide block is arranged inside each slide groove, and each slide block is provided with a conical surface fittingly contacting with the conical section. As a further improvement, the front end of the gland is further provided with a locking nut, one or more radial adjusting holes are arranged on the gland, and a positioning pin is arranged on each slide block inside the supporting ring. The general combined expanding mandrel can be adaptable to inner holes with different specifications, is accurate in positioning, and has the advantages of fine generality and strong bearing capacity.
Description
Technical field
The utility model relates to a kind of mandrel that is used for machining.
Background technology
At present, in machining, part often will use mandrel clamping processing, and when endoporus needs grinding, before and after promptly when different, or endoporus specification commonly used is not simultaneously, just needs to drop into more mandrel, in order to processing, causes cost to increase.As use common elastic central spindle, and to locate inaccurately again, interior external diameter axiality is poor, and bearing capacity is poor.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, provides a kind of common group box-like bulging mandrel, and it can be applicable to the endoporus of different size, and accurate positioning, has the advantage that versatility is good, bearing capacity is strong.
For achieving the above object, the box-like bulging mandrel of common group of the present utility model, comprise mandrel, it is characterized in that described mandrel comprises the path section, middle conical section and big footpath section, on the path section, gland is housed by screw thread, in the path section front end panel is housed slidably also, gland contacts with front end panel, one end of a front end panel and a support ring connects firmly, the other end and the rear bearing sheet of support ring connect firmly, and rear bearing sheet is loaded on the section of big footpath slidably, and support ring is provided with three roads chute radially at least, be equipped with a slide block in the per pass chute, every slide block is equipped with conical section and cooperates the conical surface that contacts.
During use, by rotating gland, promotion front end panel, support ring, slide block, rear bearing sheet move axially, conical section is radially extrapolated slide block simultaneously, slide block contacts with the endoporus of workpiece, can satisfy the needs of the part of processing different size endoporus, and provide rigid support to part, bearing capacity is strong;
As further improvement of the utility model, also be provided with locking nut at the front end of described gland; When the screw thread that uses is non-self-locking thread, can locate gland by locking nut;
As further improvement of the utility model, on gland, be provided with one or more radiai adjustment hole; In adjustment hole, insert control stick and be convenient to rotate gland;
As further improvement of the utility model, also be provided with alignment pin on the every slide block in support ring; Alignment pin can be to the stroke limit of slide block, and anti-limited slip block shifts out chute;
In sum, the utility model can be applicable to the endoporus of different size, and accurate positioning, has the advantage that versatility is good, bearing capacity is strong.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
By illustrated in figures 1 and 2, the box-like bulging mandrel of this common group, comprise mandrel 1, described mandrel 1 comprises path section 1a, middle conical section 1b and big footpath section 1c, on path section 1a, locking nut 2 and gland 3 are housed by screw thread, front end panel 4 also is housed on path section 1a slidably, locking nut 2, gland 2 contacts successively with front end panel 4, on gland 3, be provided with two adjustment holes 5 radially, one end of a front end panel 4 and a support ring 6 connects firmly by screw, the other end of support ring 6 and rear bearing sheet 7 connect firmly by screw, rear bearing sheet 7 is loaded on the big footpath section 1c slidably, and support ring 6 is provided with six roads chute radially, is equipped with a slide block 8 in the per pass chute, every slide block 8 is equipped with conical section 1b and cooperates the conical surface that contacts, and also is provided with alignment pin 9 on the every slide block 8 in support ring 6.
During use, by rotating gland 3, promotion front end panel 4, support ring 6, slide block 8, rear bearing sheet 7 move axially, again by locking nut 2 stationary gland 3, conical section 1b radially extrapolates slide block 8 simultaneously, and slide block 8 contacts with the endoporus of workpiece, can satisfy the needs of the workpiece of processing different size endoporus, and provide rigid support to workpiece, bearing capacity is strong; In actual use, also replaceable different support ring 6 and slide block 8 are promptly applicable to wider; In adjustment hole 5, insert control stick and be convenient to rotate gland 3; Alignment pin 9 can be to the stroke limit of slide block 8, and anti-limited slip block 8 shifts out chute.
